Table of contents

Organization and Classification

This SAI describes the shares of Optimum Large Cap Growth Fund, Optimum Large Cap Value Fund, Optimum Small-Mid Cap Growth Fund, Optimum Small-Mid Cap Value Fund, Optimum International Fund, and Optimum Fixed Income Fund (each a “Fund” and collectively, the “Funds”), which are series of Optimum Fund Trust (the “Trust”). Each Fund offers two retail classes: Class A shares and Class C shares (each Class individually a “Class” and collectively the “Retail Classes”). Each Fund also offers Institutional Class shares (individually a “Class” and together with the Retail Classes, the “Classes”). All references to “shares” in this SAI refer to all classes of shares of a Fund, except where noted. The Funds’ investment manager is Delaware Management Company (the “Manager” or “DMC”), a series of Macquarie Investment Management Business Trust (a Delaware statutory trust). For purposes of the “Investment Strategies and Risks” section, a reference to the Manager may also include the Funds’ sub-advisors.

Organization

The Trust was organized as a Delaware statutory trust on April 21, 2003.

Classification

The Trust is an open-end registered management investment company.

Each Fund’s portfolio of assets is “diversified” as defined by the Investment Company Act of 1940, as amended (the “1940 Act”). The 1940 Act requires a “diversified” fund, with respect to 75% of the value of its total assets, to invest (1) no more than 5% of the value of the Fund’s total assets in the securities of any one issuer and (2) in no more than 10% of the outstanding voting securities of such issuer. This limitation generally requires a diversified fund to invest in securities issued by a minimum of 16 issuers. This limitation cannot be changed without approval by the holders of a “majority” of a Fund's outstanding shares as described below.

Investment Objectives, Restrictions, and Policies

Investment Objectives

Each Fund’s investment objectives are described in the Prospectuses. Each Fund’s investment objective is nonfundamental, and may be changed without shareholder approval. However, the Trust’s Board of Trustees (“Board”) must approve any changes to nonfundamental investment objectives, and a Fund will notify shareholders at least 60 days prior to a material change in the Fund’s investment objective.

Fundamental Investment Restrictions

Each Fund has adopted the following restrictions that cannot be changed without approval by the holders of a “majority” of the Fund’s outstanding shares, which is a vote by the holders of the lesser of: (i) 67% or more of the voting securities present in person or by proxy at a meeting, if the holders of more than 50% of the outstanding voting securities are present or represented by proxy; or (ii) more than 50% of the outstanding voting securities. The percentage limitations contained in the restrictions and policies set forth herein apply at the time of purchase of securities.

Each Fund may not:

1. Purchase securities of any issuer (other than securities issued or guaranteed by the US government, its agencies or instrumentalities or securities issued by other investment companies) if, as a result, more than 5% of the Fund’s total assets would be invested in securities of that issuer or the Fund would own or hold more than 10% of the outstanding voting securities of that issuer, except that up to 25% of the Fund’s total assets may be invested without regard to this limitation.

2. Make investments that will result in the concentration (as that term may be defined in the 1940 Act, any rule or order thereunder, or U.S. Securities and Exchange Commission (“SEC”) staff interpretation thereof) of its investments in the securities of issuers primarily engaged in the same industry, provided that this restriction does not limit the Fund from investing in obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities, or in tax-exempt securities or certificates of deposit.

3. Borrow money or issue senior securities, except as the 1940 Act, any rule or order thereunder, or SEC staff interpretation thereof, may permit.

4. Underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition, or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933, as amended (the “1933 Act”).

5. Purchase or sell real estate, unless acquired as a result of ownership of securities or other instruments, and provided that this restriction does not prevent the Fund from investing in issuers that invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein.

6. Purchase or sell physical commodities, unless acquired as a result of ownership of securities or other instruments and provided that this restriction does not prevent the Fund from engaging in transactions involving futures contracts and options thereon or investing in securities that are secured by physical commodities.

7. Make personal loans or loans of its assets to persons who control or are under common control with the Fund, except as the 1940 Act, any rule or order thereunder, or SEC staff interpretation thereof, may permit. This restriction does not prevent the Fund from, among other things, purchasing debt obligations, entering into repurchase agreements, loaning its assets to broker-dealers or institutional investors, or investing in loans, including assignments and participation interests.

Nonfundamental Investment Restrictions

In addition to the fundamental policies and investment restrictions described above, and the various general investment policies described in the Prospectus, each Fund will be subject to the following investment restrictions, which are considered nonfundamental and may be changed by the Trust's Board of Trustees (“Board”) without shareholder approval. The percentage limitations contained in the restrictions and policies set forth herein apply at the time a Fund purchases securities.

1. A Fund may not invest more than 15% of its respective net assets in securities that it cannot sell or dispose of in the ordinary course of business within seven days at approximately the value at which the Fund has valued the investment.

2. A Fund may not purchase securities on margin, except for short-term credit necessary for clearance of portfolio transactions and except that the Fund may make margin deposits in connection with its use of financial options and futures, forward and spot currency contracts, swap transactions, and other financial contracts or derivatives instruments.

3. A Fund may not sell securities short or maintain a short position, except that the Fund may (a) sell short “against the box” and (b) maintain short positions in connection with its use of financial options and futures, forward and spot currency contracts, swap transactions and other financial contracts, or derivatives instruments. In addition, Optimum Fixed Income Fund may establish short positions in exchange-traded funds.

4. A Fund may not purchase portfolio securities while borrowings in excess of 5% of its total assets are outstanding.

Except for the Funds’ policy with respect to borrowing, any investment restriction or limitation that involves a maximum percentage of securities or assets shall not be considered to be violated unless an excess over the percentage occurs immediately after an acquisition of securities or a utilization of assets and such excess results therefrom.

Portfolio Turnover

Portfolio trading will be undertaken principally to accomplish each Fund’s respective investment objective. The Funds are free to dispose of portfolio securities at any time, subject to complying with the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and the 1940 Act, when changes in circumstances or conditions make such a move desirable in light of each Fund’s respective investment objective. The Funds will not attempt to achieve or be limited to a predetermined rate of portfolio turnover. Such turnover always will be incidental to transactions undertaken with a view to achieving each Fund’s respective investment objective.

The portfolio turnover rate tells you the amount of trading activity in a Fund’s portfolio. A turnover rate of 100% would occur, for example, if all of a Fund’s investments held at the beginning of a year were replaced by the end of the year, or if a single investment was frequently traded. The turnover rate also may be affected by cash requirements from redemptions and repurchases of a Fund’s shares. A high rate of portfolio turnover in any year may increase brokerage commissions paid and could generate taxes for shareholders on realized investment gains. In investing to achieve its investment objective, a Fund may hold securities for any period of time.

For the fiscal years ended March 31, 2022 and 2021, the Funds’ portfolio turnover rates were as follows:

Investment Strategies and Risks

The Funds’ investment objectives, strategies, and risks are described in the Prospectus. Certain additional information is provided below. The following discussion supplements the description of the Funds’ investment strategies and risks that are included in the Prospectus. The Funds’ investment strategies are nonfundamental and may be changed without shareholder approval.

Asset-Backed Securities (“ABS”)

The Funds may invest a portion of their assets in ABS.

Asset-backed receivables are securitized in either a pass-through or a pay-through structure. Pass-through securities provide investors with an income stream consisting of both principal and interest payments in respect of the receivables in the underlying pool. Pay-through ABS are debt obligations issued usually by a special purpose entity. The securities are collateralized by the various receivables and the payments on the underlying receivables provide the proceeds to pay the debt service on the debt obligations issued.

The rate of principal payment on ABS generally depends on the rate of principal payments received on the underlying assets. Such rate of payments may be affected by economic and various other factors such as changes in interest rates or the concentration of collateral in a particular geographic area. Therefore, the yield may be difficult to predict and actual yield to maturity may be more or less than the anticipated yield to maturity. The credit quality of most ABS depends primarily on the credit quality of the assets underlying such securities, how well the entities issuing the securities are insulated from the credit risk of the originator or affiliated entities, and the amount of credit support provided to the securities. Due to the shorter maturity of the collateral backing such securities, there tends to be less of a risk of substantial prepayment than with mortgage-backed securities (“MBS”) but the risk of such a prepayment does exist. Such ABS do, however, involve certain risks not associated with MBS, including the risk that security interests cannot be adequately, or in many cases ever, established, and other risks that may be peculiar to particular classes of collateral. For example, with respect to credit card receivables, a number of state and federal consumer credit laws give debtors the right to set off certain amounts owed on the credit cards, thereby reducing the outstanding balance. In the case of automobile receivables, there is a risk that the holders may not have either a proper or first security interest in all of the obligations backing such receivables due to the large number of vehicles involved in a typical issuance and technical requirements under state laws; therefore, recoveries on repossessed collateral may not always be available to support payments on the securities.

ABS are often backed by a pool of assets representing the obligations of a number of different parties. To lessen the effect of failures by obligors on underlying assets to make payments, such securities may contain elements of credit support. Such credit support falls into two categories: (i) liquidity protection, and (ii) protection against losses resulting from ultimate default by an obligor on the underlying assets. Liquidity protection refers to the provision of advances, generally by the entity administering the pool of assets, to ensure that the receipt of payments due on the underlying pool is timely. Protection against losses resulting from ultimate default enhances the likelihood of payments of the obligations on at least some of the assets in the pool. Such protection may be provided through guarantees, insurance policies, or letters of credit obtained by the issuer or sponsor from third parties, through various means of structuring the transaction, or through a combination of such approaches. The Funds will not pay any additional fees for such credit support, although the existence of credit support may increase the price of a security.

Examples of credit support arising out of the structure of the transaction include “senior-subordinated securities” (multiple-class securities with one or more classes subordinate to other classes as to the payment of principal thereof and interest thereon, with the result that defaults on the underlying assets are borne first by the holders of the subordinated class), creation of “reserve funds” (where cash or investments, sometimes funded from a portion of the payments on the underlying assets, are held in reserve against future losses), and “over collateralization” (where the scheduled payments on, or the principal amount of, the underlying assets exceed that required to make payments of the securities and pay any servicing or other fees). The degree of credit support provided for each issue is generally based on historical information respecting the level of credit risk associated with the underlying assets. Delinquencies or losses in excess of those anticipated could adversely affect the return on an investment in such issue.

Bank Capital Securities

Optimum Fixed Income Fund may invest in bank capital securities. Bank capital securities are issued by banks to help fulfill their regulatory capital requirements. There are three common types of bank capital: Lower Tier II, Upper Tier II, and Tier I. Bank capital is generally, but not always, of investment grade quality. Upper Tier II securities are commonly thought of as hybrids of debt and preferred stock. Upper Tier II securities are often perpetual (with no maturity date), callable, and have a cumulative interest deferral feature. This means that under certain conditions, the issuer bank can withhold payment of interest until a later date. However, such deferred interest payments generally earn interest. Tier I securities often take the form of trust-preferred securities.

Brady Bonds

The Funds may invest in Brady Bonds.

Brady Bonds are securities created through the exchange of existing commercial bank loans to public and private entities in certain emerging markets for new bonds in connection with debt restructurings under a debt restructuring plan introduced by former US Secretary of the Treasury, Nicholas F. Brady (the “Brady Plan”). Brady Plan debt restructurings have been implemented in a number of countries including Argentina, Brazil, Bulgaria, Costa Rica, Croatia, Dominican Republic, Ecuador, Jordan, Mexico, Morocco, Nigeria, Panama, Peru, the Philippines, Poland, Slovenia, Uruguay, and Venezuela. Brady Bonds may be collateralized or uncollateralized, are issued in various currencies (but primarily the US dollar), and are actively traded in over-the-counter secondary markets. US dollar-denominated, collateralized Brady Bonds, which may be fixed-rate bonds or floating-rate bonds, are generally collateralized in full as to principal by US Treasury zero coupon bonds having the same maturity as the bonds. Brady Bonds are often viewed as having three or four valuation components: the collateralized repayment of principal at final maturity, the collateralized interest payments, the uncollateralized interest payments, and any uncollateralized repayment of principal at maturity (these uncollateralized amounts constituting the “residual risk”). In light of the residual risk of Brady Bonds and the history of defaults of countries issuing Brady Bonds with respect to commercial bank loans by public and private entities, investments in Brady Bonds may be viewed as speculative.

Collateralized Debt Obligations

Optimum Fixed Income Fund may invest in each of collateralized bond obligations (“CBOs”), collateralized loan obligations (“CLOs”), other collateralized debt obligations (“CDOs”) and other similarly structured securities. CBOs, CLOs and other CDOs are types of asset-backed securities. A CBO is a trust that is backed by a diversified pool of high risk, below investment grade fixed income securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. CDOs may charge management fees and administrative expenses.

For both CBOs and CLOs, the cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. The riskiest portion is the “equity” tranche which bears the bulk of defaults from the bonds or loans in the trust and serves to protect the other, more senior tranches from default in all but the most severe circumstances. Since they are partially protected from defaults, senior tranches from a CBO trust or CLO trust typically have higher ratings and lower yields than their underlying securities, and can be rated investment grade. Despite the protection from the equity tranche, CBO or CLO tranches can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults, as well as aversion to CBO or CLO securities as a class.

The risks of an investment in a CDO depend largely on the type of the collateral securities and the class of the CDO in which the Fund invests. Normally, CBOs, CLOs and other CDOs are privately offered and sold, and thus, are not registered under the securities laws. As a result, investments in CDOs may be characterized by the Funds as illiquid investments, however an active dealer market may exist for CDOs allowing a CDO to qualify for Rule 144A transactions. In addition to the normal risks associated with fixed income securities, CDOs carry additional risks including, but not limited to, the possibility that: (i) distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral securities may decline in value or there may be a default in one or more of the collateral securities; (iii) the CDOs in which the Funds may invest will be subordinate to other classes; and (iv) the complex structure of a collateralized security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

Combined Transactions

The Funds may enter into combined transactions.

Combined transactions may include multiple options transactions; multiple futures transactions; multiple currency transactions (including forward foreign currency contracts) and multiple interest rate transactions; and any combination of futures, options, currency, and interest rate transactions (“component” transactions) instead of a single transaction, as part of a single or combined strategy when, in the opinion of the Manager, it is in the best interests of a Fund to do so. A combined transaction will usually contain elements of risk that are present in each of its component transactions. Although combined transactions are normally entered into based on the Manager’s judgment that the combined strategies will reduce risk or otherwise more effectively achieve the desired portfolio management goal, it is possible that the combination will instead increase such risks or hinder achievement of the portfolio management objective.

Convertible Securities

A portion of the Funds’ assets may be invested in convertible and debt securities of issuers in any industry.

A convertible security is generally a debt obligation, preferred stock or other security that may be converted within a specified period of time into a certain amount of common stock of the same or a different issuer. Convertible securities rank ahead of common stock in a corporation’s capital structure and therefore entail less risk than the corporation’s common stock. However, convertible securities typically rank behind non-convertible securities of the same issuer. Convertible and debt securities provide a fixed income stream and the opportunity, through their conversion features, to participate in the capital appreciation resulting from a market price advance in the convertible securities’ underlying common stock. A convertible security’s price depends on both its “investment value” (its value with the conversion privilege), and its “conversion value” (its market value if it were exchanged for the underlying security according to its conversion privilege). When a convertible security’s investment value is greater than its conversion value, its price will primarily reflect its investment value. In this scenario, price will probably be most affected by interest rate changes, increasing when interest rates fall and decreasing when interest rates rise, similar to a fixed income security. Additionally, the credit standing of the issuer and other factors also may have an effect on the convertible security’s value. Conversely, when the conversion value approaches or exceeds the investment value, the price of the convertible security will rise above its investment value. The higher the convertible security’s price relative to its investment value, the more direct the relationship between the changes in its price and changes in the price of the underlying equity security.

A convertible security’s price will typically provide a premium over the conversion value. This represents the additional price investors are willing to pay for a security that offers income, ranks ahead of common stock in a company’s capital structure and also has the possibility of capital appreciation due to the conversion privilege. Because a convertible security has fixed interest or dividend payments, when the underlying stock declines, the convertible security’s price is increasingly determined by its yield. For this reason, the convertible security may not decline as much as the underlying common stock. The extent of the price decline will also depend on the amount of the premium over its conversion value.

Common stock acquired upon conversion of a convertible security will generally be held for as long as the investment manager anticipates such stock will provide a Fund with opportunities that are consistent with its investment objectives and policies.

A Fund may invest in convertible debentures without regard to rating categories. Investing in convertible debentures that are rated below investment grade or unrated but of comparable quality entails certain risks, including the risk of loss of principal, which may be greater than the risks involved in investing in

investment grade convertible debentures. Under rating-agency guidelines, lower rated securities and comparable unrated securities will likely have some quality and protective characteristics that are outweighed by large uncertainties or major risk exposures to adverse conditions.

A Fund may have difficulty disposing of such lower rated convertible debentures because the trading market for such securities may be thinner than the market for higher rated convertible debentures. To the extent a secondary trading market for these securities does exist, it generally is not as liquid as the secondary trading market for higher rated securities. The lack of a liquid secondary market, as well as adverse publicity with respect to these securities, may have an adverse impact on market price and a Fund’s ability to dispose of particular issues in response to a specific economic event such as deterioration in the creditworthiness of the issuer. The lack of a liquid secondary market for certain securities also may make it more difficult for a Fund to obtain accurate market quotations for purposes of pricing the Fund’s portfolio and calculating its net asset value (“NAV”). The market behavior of convertible securities in lower rating categories is often more volatile than that of higher quality securities. Lower quality convertible securities are judged by Moody’s Investors Service, Inc. (“Moody’s”) and Standard & Poor’s Financial Services LLC (“S&P”) to have speculative elements or characteristics; their future cannot be considered as well assured, and their earnings and asset protection may be moderate or poor in comparison to investment grade securities.

In addition, such lower quality securities face major ongoing uncertainties or exposure to adverse business, financial or economic conditions, which could lead to inadequate capacity to meet timely payments. The market values of securities rated below investment grade tend to be more sensitive to company-specific developments and changes in economic conditions than higher rated securities. Issuers of these securities are often highly leveraged so that their ability to service their debt obligations during an economic downturn or during sustained periods of rising interest rates may be impaired. In addition, such issuers may not have more traditional methods of financing available to them, and therefore may be unable to repay debt at maturity by refinancing.

A Fund may invest in convertible preferred stocks that offer enhanced yield features, such as Preferred Equity Redemption Cumulative Stock (“PERCS”), which provide an investor with the opportunity to earn higher dividend income than is available on a company’s common stock. A PERCS is a preferred stock that generally features a mandatory conversion date, as well as a capital appreciation limit, which is usually expressed in terms of a stated price. Upon the conversion date, most PERCS convert to common stock of the issuer (PERCS are generally not convertible to cash at maturity). Under a typical arrangement, if after a predetermined number of years the issuer’s common stock is trading at a price below that set by the capital appreciation limit, each PERCS would convert to one share of common stock. If, however, the issuer’s common stock is trading at a price above that set by the capital appreciation limit, the holder of the PERCS would receive less than one full share of common stock. The amount of that fractional share of common stock received by the PERCS holder is determined by dividing the price set by the capital appreciation limit of the PERCS by the market price of the issuer’s common stock. PERCS can be called at any time prior to maturity, and hence do not provide call protection. However, if called early, the issuer may pay a call premium over the market price to the investor. This call premium declines at a preset rate daily, up to the maturity date of the PERCS.

A Fund also may invest in other enhanced convertible securities. These include but are not limited to ACES (Automatically Convertible Equity Securities), PEPS (Participating Equity Preferred Stock), PRIDES (Preferred Redeemable Increased Dividend Equity Securities), SAILS (Stock Appreciation Income Linked Securities), TECONS (Term Convertible Notes), QICS (Quarterly Income Cumulative Securities) and DECS (Dividend Enhanced Convertible Securities). ACES, PEPS, PRIDES, SAILS, TECONS, QICS and DECS all have the following features: they are company-issued convertible preferred stock; unlike PERCS, they do not have capital appreciation limits; they seek to provide the investor with high current income, with some prospect of future capital appreciation; they are typically issued with 3- to 4-year maturities; they typically have some built-in call protection for the first two to three years; investors have the right to convert them into shares of common stock at a preset conversion ratio or hold them until maturity; and upon maturity, they automatically convert to either cash or a specified number of shares of common stock. An investment in such securities may involve additional risks. Unlike conventional convertible securities, enhanced convertible securities do not usually have a fixed maturity (par) value. Rather, such securities generally provide only for a mandatory conversion to cash or common stock. As a result, a Fund risks loss of principal if the cash received, or the price of the underlying common stock at the time of conversion, is less than the price paid for the enhanced convertible security. Such securities may be more or less liquid than conventional convertible securities or non-convertible debt securities.

A “synthetic” convertible security may be created by combining separate securities that possess the two principal characteristics of a traditional convertible security, i.e., an income-producing security (“income-producing component”) and the right to acquire an equity security (“convertible component”). The income-producing component is achieved by investing in non-convertible, income-producing securities such as bonds, preferred stocks and money market instruments, which may be represented by derivatives instruments. The convertible component is achieved by investing in securities or instruments such as warrants or options to buy common stock at a certain exercise price, or options on a stock index. Unlike a traditional convertible security, which is a single security having a single market value, a synthetic convertible comprises two or more separate securities, each with its own market value. Therefore, the “market value” of a synthetic convertible security is the sum of the values of its income-producing component and its convertible component. For this reason, the values of a synthetic convertible security and a traditional convertible security may respond differently to market fluctuations.

More flexibility is possible in the assembly of a synthetic convertible security than in the purchase of a convertible security. Although synthetic convertible securities may be selected where the two components are issued by a single issuer, thus making the synthetic convertible security similar to the traditional convertible security, the character of a synthetic convertible security allows the combination of components representing distinct issuers, when it is believed that such a combination may better achieve a Fund’s investment objective. A synthetic convertible security also is a more flexible investment in that its two components may be purchased separately. For example, a Fund may purchase a warrant for inclusion in a synthetic convertible security but temporarily hold short-term investments while postponing the purchase of a corresponding bond pending development of more favorable market conditions.

A holder of a synthetic convertible security faces the risk of a decline in the price of the security or the level of the index involved in the convertible component, causing a decline in the value of the security or instrument, such as a call option or warrant, purchased to create the synthetic convertible security. Should the

price of the stock fall below the exercise price and remain there throughout the exercise period, the entire amount paid for the call option or warrant would be lost. Because a synthetic convertible security includes the income-producing component as well, the holder of a synthetic convertible security also faces the risk that interest rates will rise, causing a decline in the value of the income-producing component.

A Fund also may purchase synthetic convertible securities created by other parties, including convertible structured notes. Convertible structured notes are income-producing debentures linked to equity, and are typically issued by investment banks. Convertible structured notes have the attributes of a convertible security; however, the investment bank that issues the convertible note, rather than the issuer of the underlying common stock into which the note is convertible, assumes credit risk associated with the underlying investment, and the Fund in turn assumes credit risk associated with the convertible note.

Risks. An investment in a convertible security may involve risks. A Fund may have difficulty disposing of such securities because there may be a thin trading market for a particular security at any given time. Reduced liquidity may have an adverse impact on market price and a Fund’s ability to dispose of a security when necessary to meet the Fund’s liquidity needs or in response to a specific economic event, such as the deterioration in the creditworthiness of an issuer. Reduced liquidity in the secondary market for certain securities may also make it more difficult for a Fund to obtain market quotations based on actual trades for purposes of valuing the Fund’s portfolio. Although a Fund intends to acquire convertible securities that the Manager considers to be liquid (i.e., those securities that the Manager determines may be sold on an exchange, or an institutional or other substantial market), there can be no assurances that this will be achieved. Certain securities and markets can become illiquid quickly, resulting in liquidity risk for the Fund. A Fund may also encounter difficulty valuing convertible securities due to illiquidity or other circumstances that make it difficult for the Fund to obtain timely market quotations based on actual trades for convertible securities.

Corporate Reorganizations

A Fund may invest in securities for which a tender or exchange offer has been made or announced and in securities of companies for which a merger, consolidation, liquidation or reorganization proposal has been announced if, in the judgment of the investment adviser, it is consistent with the Fund’s investment objective and policies. The primary risk of such investments is that if the contemplated transaction is abandoned, revised, delayed or becomes subject to unanticipated uncertainties, the market price of the securities may decline below the purchase price paid by the Fund.

In general, securities that are the subject of such an offer or proposal sell at a premium to their historic market price immediately prior to the announcement of the offer or proposal. However, the increased market price of such securities may also discount what the stated or appraised value of the security would be if the contemplated transaction were approved or consummated. Such investments may be advantageous when the discount significantly overstates the risk of the contingencies involved; significantly undervalues the securities, assets or cash to be received by shareholders of the prospective company as a result of the contemplated transaction; or fails adequately to recognize the possibility that the offer or proposal may be replaced or superseded by an offer or proposal of greater value. The evaluation of such contingencies requires unusually broad knowledge and experience on the part of the investment adviser, which must appraise not only the value of the issuer and its component businesses, but also the financial resources and business motivation of the offeror as well as the dynamics of the business climate when the offer or proposal is in process.

Custodial Receipts

A Fund may acquire US government securities and their unmatured interest coupons that have been separated (“stripped”) by their holder, typically a custodian bank or investment brokerage firm. Having separated the interest coupons from the underlying principal of the US government securities, the holder will resell the stripped securities in custodial receipt programs with a number of different names, including Treasury Receipts (“TRs”), Treasury Investment Growth Receipts (“TIGRs”), and Certificates of Accrual on Treasury Securities (“CATS”). TIGRs and CATS are interests in private proprietary accounts while TRs and Treasury Separate Trading of Registered Interest and Principal of Securities (“STRIPS”) are interests in accounts sponsored by the US Treasury. The custodian holds the interest and principal payments for the benefit of the registered owners of the certificates or receipts. The custodian arranges for the issuance of the certificates or receipts evidencing ownership and maintains the register. The stripped coupons are sold separately from the underlying principal, which is usually sold at a deep discount because the buyer receives only the right to receive a future fixed payment on the security and does not receive any rights to periodic interest (cash) payments. The underlying US Treasury bonds and notes themselves are generally held in book-entry form at a Federal Reserve Bank. Purchasers of the stripped securities generally are treated as the beneficial holders of the underlying US government securities for federal tax and securities purposes.

Depositary Receipts

A Fund may invest in foreign companies through the purchase and sale of sponsored or unsponsored American, European, and Global Depositary Receipts (“ADRs,” “EDRs,” and “GDRs,” respectively, and collectively, “depositary receipts”).

Many securities of foreign issuers are represented by ADRs, GDRs, and EDRs. Generally, depositary receipts in registered form are designed for use in the US securities market and depositary receipts in bearer form are designed for use in securities markets outside the United States. ADRs evidence ownership of, and represent the right to receive, securities of foreign issuers deposited in a domestic bank or trust company or a foreign correspondent bank. Prices of ADRs are quoted in US dollars, and ADRs are traded in the US on exchanges or over-the-counter. While ADRs do not eliminate all the risks associated with foreign investments, by investing in ADRs rather than directly in the stock of foreign issuers, a Fund will avoid currency and certain foreign market trading risks during the settlement period for either purchases or sales. In general, there is a large, liquid market in the US for ADRs quoted on a national securities

exchange. The information available for ADRs is subject to the accounting, auditing, and financial reporting standards of the US market or exchange on which they are traded, which standards are generally more uniform and more exacting than those to which many foreign issuers may be subject.

EDRs and GDRs are typically issued by foreign banks or trust companies and evidence ownership of underlying securities issued by either a foreign or a US corporation. EDRs and GDRs may not necessarily be denominated in the same currency as the underlying securities into which they may be converted. The underlying shares are held in trust by a custodian bank or similar financial institution in the issuer’s home country. If the issuer’s home country does not have developed financial markets, a Fund could be exposed to the credit risk of the custodian or financial institution and greater market risk.

The depository bank may not have physical custody of the underlying securities at all times and may charge fees for various services, including forwarding dividends and interest and corporate actions. A Fund would be expected to pay a share of the additional fees, which it would not pay if investing directly in the foreign securities. A Fund may experience delays in receiving its dividend and interest payments or exercising rights as a shareholder.

Depositary receipts may reduce some but not eliminate all the risks inherent in investing in the securities of foreign issuers. Depositary receipts are still subject to the political and economic risks of the underlying issuer’s country and are still subject to foreign currency exchange risk. Depositary receipts will be issued under sponsored or unsponsored programs. In sponsored programs, an issuer has made arrangements to have its securities traded in the form of depositary receipts. In unsponsored programs, the issuer may not be directly involved in the creation of the program. Although regulatory requirements with respect to sponsored and unsponsored programs are generally similar, in some cases it may be easier to obtain financial information about an issuer that has participated in the creation of a sponsored program. There may be an increased possibility of untimely responses to certain corporate actions of the issuer, such as stock splits and rights offerings, in an unsponsored program. Accordingly, there may be less information available regarding issuers of securities underlying unsponsored programs and there may not be a correlation between this information and the market value of the depositary receipts. If a Fund’s investment depends on obligations being met by the arranger as well as the issuer of an unsponsored program, the Fund will be exposed to additional credit risk.

Derivatives Instruments

The Funds may invest in some or all of the following types of derivatives instruments: forward foreign currency contracts, futures, options, and swaps, all of which are described in more detail in this section of the SAI.

Generally, derivatives are financial instruments whose values depend on or are derived from the value of one or more underlying assets, reference rates, indices, or other market factors (a “reference instrument”) and may relate to stocks, bonds, interest rates, currencies, commodities, or related indices. Derivative instruments allow a Fund to gain or reduce exposure to the value of a reference instrument without actually owning or selling the instrument.

The Funds may value derivatives instruments at market value, notional value, or full exposure value (i.e., the sum of the notional amount for the contract plus the market value). The manner in which certain securities or other instruments are valued by the Funds may differ from the manner in which those investments are valued by other types of investors.

Exclusion from commodity pool operator definition. The Manager has claimed an exclusion from the definition of “commodity pool operator” (“CPO”) with respect to the Funds under the Commodity Exchange Act (“CEA”) and the rules of the Commodity Futures Trading Commission (“CFTC”) and, therefore, is not subject to CFTC registration or regulation as a CPO. In addition, the Manager, although registered as a commodity trading advisor (“CTA”) with the CFTC, provides commodity interest trading advice to the Funds as if the Manager was exempt from CTA registration in reliance on applicable rules of the CFTC.

The terms of the CPO exclusion require a Fund, among other things, to adhere to certain limits on its investments in “commodity interests.” Commodity interests include commodity futures, commodity options, and certain swaps, which in turn include nondeliverable currency forwards, as further described below. Because the Manager intends to comply with the terms of the CPO exclusion with respect to the Funds, each Fund may, in the future, need to adjust its investment strategies, consistent with its investment goal, to limit its investments in these types of instruments. The Funds are not intended as vehicles for trading in the commodity futures, commodity options, or swaps markets. The CFTC has neither reviewed nor approved the Manager’s reliance on the CPO exclusion, the Manager’s provision of services as an exempt CTA or a Fund, its investment strategies, or this SAI.

Generally, the exclusion from CPO definition and regulation on which the Manager relies requires a Fund to meet one of the following tests for its commodity interest positions, other than positions entered into for bona fide hedging purposes (as defined in the rules of the CFTC): either (1) the aggregate initial margin and premiums required to establish the Funds' positions in commodity interests may not exceed 5% of the liquidation value of the Funds' portfolio (after taking into account unrealized profits and unrealized losses on any such positions); or (2) the aggregate net notional value of the Funds' commodity interest positions, determined at the time the most recent such position was established, may not exceed 100% of the liquidation value of the Funds' portfolio (after taking into account unrealized profits and unrealized losses on any such positions). In addition to meeting one of these trading limitations, a Fund may not be marketed as a commodity pool or otherwise as a vehicle for trading in the commodity futures, commodity options, or swaps markets. If, in the future, a Fund can no longer satisfy these requirements, the Manager would withdraw the notice claiming an exclusion from the definition of a CPO for the Fund, and the Manager would be subject to registration and regulation as a CPO with respect to the Fund, in accordance with CFTC rules that apply to CPOs of registered investment companies. Generally, these rules allow for substituted compliance with CFTC disclosure and shareholder reporting requirements, based on the Manager’s compliance with comparable SEC requirements. However, as a result of CFTC regulation, a Fund may incur additional compliance and other expenses.

Developing government regulation of derivatives. The regulation of cleared and uncleared swaps, as well as other derivatives, is a rapidly changing area of law and is subject to modification by government and judicial action. In addition, the SEC, CFTC, and the exchanges are authorized to take extraordinary actions in the event of a market emergency, including, for example, the implementation or reduction of speculative position limits, the implementation of higher margin requirements, the establishment of daily price limits, and the suspension of trading.

The SEC recently adopted new Rule 18f-4 under the 1940 Act, which imposes limits on the amount of derivatives a fund can enter into and replaces the asset segregation framework previously used by certain funds to comply with Section 18 of the 1940 Act, among other requirements. Effective August 19, 2022, to the extent a Fund uses derivatives, the Fund complies with the applicable requirements and conditions of Rule 18f-4.

It is not possible to predict fully the effects of current or future regulation. However, it is possible that developments in government regulation of various types of derivatives instruments may prevent the Funds from using or limit the Funds' use of these instruments effectively as a part of its investment strategy, and could adversely affect the Funds' ability to achieve its investment goal(s). The Manager will continue to monitor developments in this area. New requirements, even if not directly applicable to a Fund, may increase the cost of the Funds' investments and cost of doing business.

Exchange-Traded Funds

Each Fund may invest in exchange-traded funds.

Exchange-traded funds (“ETFs”) are a type of index fund bought and sold on a securities exchange. An ETF trades like common stock and represents a fixed portfolio of securities designed to track a particular market index. A Fund could purchase an ETF to temporarily gain exposure to a portion of the US market or a foreign market while awaiting purchase of underlying securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities they are designed to track, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs.

Foreign Investments

Each Fund may invest in foreign securities.

Overview. Investors should consider carefully the substantial risks associated with investing in the securities of certain governments and companies located in, or having substantial operations in, foreign countries, which are in addition to the usual risks inherent in domestic investments. As with US securities, the value of foreign securities is affected by general economic conditions and individual issuer and industry earnings prospects. Investments in depositary receipts also involve some or all of the risks described below.

There is the possibility of cessation of trading on foreign exchanges, expropriation, nationalization of assets, confiscatory or punitive taxation, withholding and other foreign taxes on income or other amounts, foreign exchange controls (which may include suspension of the ability to transfer currency from a given country), restrictions on removal of assets, political or social instability, military action or unrest, or diplomatic developments that could affect investments in securities of issuers in foreign nations. There is no assurance that the Manager will be able to anticipate these potential events. In addition, the value of securities denominated in foreign currencies and of dividends and interest paid with respect to such securities will fluctuate based on the relative strength of the US dollar compared to such foreign currencies.

There may be less publicly available information about foreign issuers that is comparable to the reports and ratings published about issuers in the US. Foreign issuers generally are not subject to uniform accounting or financial reporting standards. Auditing practices and requirements may not be comparable to those applicable to US issuers. Certain countries’ legal institutions, financial markets, and services are less developed than those in the US or other major economies. A Fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends and obtaining information regarding corporate actions on a timely basis, pursuing legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect to domestic issuers in US courts. The costs associated with foreign investments, including withholding taxes, brokerage commissions, and custodial costs, are generally higher than with US investments.

Certain countries require governmental approval prior to investments by foreign persons, or limit the amount of investment by foreign persons in a particular company. Some countries limit the investment of foreign persons to only a specific class of securities of an issuer that may have less advantageous terms than securities of the issuer available for purchase by nationals. Although securities subject to such restrictions may be marketable abroad, they may be less liquid than foreign securities of the same class that are not subject to such restrictions. In some countries the repatriation of investment income, capital, and proceeds of sales by foreign investors may require governmental registration and/or approval. A Fund could be adversely affected by delays in or a refusal to grant any required governmental registration or approval for repatriation.

From time to time, trading in a foreign market may be interrupted. Foreign markets also have substantially less volume than the US markets and securities of some foreign issuers are less liquid and more volatile than securities of comparable US issuers. A Fund, therefore, may encounter difficulty in obtaining market quotations for purposes of valuing its portfolio and calculating its net asset value (“NAV”).

In many foreign countries, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in the US, which may result in greater potential for fraud or market manipulation. Foreign over-the-counter markets tend to be less regulated than foreign stock exchange markets and, in certain countries, may be totally unregulated. Brokerage commission rates in foreign countries, which generally are fixed rather than subject to negotiation as in the US, are likely to be higher. Foreign security trading, settlement, and custodial practices (including those involving securities settlement

where assets may be released prior to receipt of payment) are often less developed than those in US markets, may be cumbersome, and may result in increased risk or substantial delays. This could occur in the event of a failed trade or the insolvency of, or breach of duty by, a foreign broker/dealer, securities depository, or foreign subcustodian.

To the extent that a Fund invests a significant portion of its assets in a specific geographic region or country, the Fund will have more exposure to economic risks related to such region or country than a fund whose investments are more geographically diversified. Adverse conditions or changes in policies in a certain region or country can affect securities of other countries whose economies appear to be unrelated but are otherwise connected. In the event of economic or political turmoil, a deterioration of diplomatic relations or a natural or man-made disaster in a region or country where a substantial portion of a Fund’s assets are invested, the Fund may have difficulty meeting a large number of shareholder redemption requests.

The holding of foreign securities may be limited by a Fund to avoid investment in certain Passive Foreign Investment Companies (“PFICs”).

Developing markets or emerging markets. Investments in companies domiciled or with significant operations in developing market or emerging market countries may be subject to potentially higher risks than investments in developed countries. These risks include, among others (i) less social, political, and economic stability; (ii) smaller securities markets with low or nonexistent trading volume, which result in greater illiquidity and greater price volatility; (iii) certain national policies which may restrict a Fund’s investment opportunities, including restrictions on investment in issuers or industries deemed sensitive to national interests; (iv) foreign taxation, including less transparent and established taxation policies; (v) less developed regulatory or legal structures governing private or foreign investment or allowing for judicial redress for injury to private property; (vi) the absence, until recently in many developing market countries, of a capital market structure or market-oriented economy; (vii) more widespread corruption and fraud; (viii) the financial institutions with which a Fund may trade may not possess the same degree of financial sophistication, creditworthiness, or resources as those in developed markets; and (ix) the possibility that recent favorable economic developments in some developing market countries may be slowed or reversed by unanticipated economic, political, or social events in such countries.

In addition, many developing market countries have experienced substantial and, during some periods, extremely high rates of inflation, for many years. Inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and securities markets of certain countries. Moreover, the economies of some developing market countries may differ unfavorably from the US economy in such respects as growth of gross domestic product, rate of inflation, currency depreciation, debt burden, capital reinvestment, resource self-sufficiency, and balance of payments position. The economies of some developing market countries may be based on only a few industries, and may be highly vulnerable to changes in local or global trade conditions.

Settlement systems in developing market countries may be less organized than in developed countries. Supervisory authorities may also be unable to apply standards which are comparable with those in more developed countries. There may be risks that settlement may be delayed and that cash or securities belonging to a Fund may be in jeopardy because of failures of or defects in the settlement systems. Market practice may require that payment be made prior to receipt of the security which is being purchased or that delivery of a security must be made before payment is received. In such cases, default by a broker or bank (the “counterparty”) through whom the relevant transaction is effected might result in a loss being suffered by a Fund. A Fund seeks, where possible, to use counterparties whose financial status reduces this risk. However, there can be no certainty that the Fund will be successful in eliminating or reducing this risk, particularly as counterparties operating in developing market countries frequently lack the substance, capitalization, and/or financial resources of those in developed countries. Uncertainties in the operation of settlement systems in individual markets may increase the risk of competing claims to securities held by or to be transferred to a Fund. Legal compensation schemes may be nonexistent, limited, or inadequate to meet a Fund’s claims in any of these events.

Securities trading in developing markets presents additional credit and financial risks. A Fund may have limited access to, or there may be a limited number of, potential counterparties that trade in the securities of developing market issuers. Governmental regulations may restrict potential counterparties to certain financial institutions located or operating in the particular developing market. Potential counterparties may not possess, adopt, or implement creditworthiness standards, financial reporting standards, or legal and contractual protections similar to those in developed markets. Currency and other hedging techniques may not be available or may be limited.

The local taxation of income and capital gains accruing to nonresidents varies among developing market countries and may be comparatively high. Developing market countries typically have less well-defined tax laws and procedures and such laws may permit retroactive taxation so that a Fund could in the future become subject to local tax liabilities that had not been anticipated in conducting its investment activities or valuing its assets.

Many developing market countries suffer from uncertainty and corruption in their legal frameworks. Legislation may be difficult to interpret and laws may be too new to provide any precedential value. Laws regarding foreign investment and private property may be weak or nonexistent. Investments in developing market countries may involve risks of nationalization, expropriation, and confiscatory taxation. For example, the Communist governments of a number of Eastern European countries expropriated large amounts of private property in the past, in many cases without adequate compensation, and there can be no assurance that similar expropriation will not occur in the future. In the event of expropriation, a Fund could lose all or a substantial portion of any investments it has made in the affected countries. Accounting, auditing, and reporting standards in certain countries in which a Fund may invest may not provide the same degree of investor protection or information to investors as would generally apply in major securities markets. In addition, it is possible that purported securities in which a Fund invested may subsequently be found to be fraudulent and as a consequence the Fund could suffer losses.

Finally, currencies of developing market countries are subject to significantly greater risks than currencies of developed countries. Some developing market currencies may not be internationally traded or may be subject to strict controls by local governments, resulting in undervalued or overvalued currencies and

associated difficulties with the valuation of assets, including a Fund’s securities, denominated in that currency. Some developing market countries have experienced balance of payment deficits and shortages in foreign exchange reserves. Governments have responded by restricting currency conversions. Future restrictive exchange controls could prevent or restrict a company’s ability to make dividend or interest payments in the original currency of the obligation (usually US dollars). In addition, even though the currencies of some developing market countries, such as certain Eastern European countries, may be convertible into US dollars, the conversion rates may be artificial to the actual market values and may be adverse to a Fund’s shareholders.

Foreign governmental and supranational debt securities. Investments in debt securities of foreign governmental or supranational issuers are subject to all the risks associated with investments in US and foreign securities and certain additional risks.

Foreign government debt securities, sometimes known as sovereign debt securities, include debt securities issued, sponsored, or guaranteed by: governments or governmental agencies, instrumentalities, or political subdivisions located in emerging or developed market countries; government owned, controlled, or sponsored entities located in emerging or developed market countries; and entities organized and operated for the purpose of restructuring the investment characteristics of instruments issued by any of the above issuers.

A supranational entity is a bank, commission, or company established or financially supported by the national governments of one or more countries to promote reconstruction, trade, harmonization of standards or laws; economic development; and humanitarian, political, or environmental initiatives. Supranational debt obligations include: Brady Bonds; participations in loans between emerging market governments and financial institutions; and debt securities issued by supranational entities such as the World Bank, Asia Development Bank, European Investment Bank, and the European Economic Community.

Foreign government debt securities are subject to risks in addition to those relating to debt securities generally. Governmental issuers of foreign debt securities may be unwilling or unable to pay interest and repay principal, or otherwise meet obligations, when due and may require that the conditions for payment be renegotiated. As a sovereign entity, the issuing government may be immune from lawsuits in the event of its failure or refusal to pay the obligations when due. The debtor’s willingness or ability to repay in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its non-US reserves, the availability of sufficient non-US exchange on the date a payment is due, the relative size of the debt service burden to the issuing country’s economy as a whole, the sovereign debtor’s policy toward principal international lenders, such as the International Monetary Fund or the World Bank, and the political considerations or constraints to which the sovereign debtor may be subject. Governmental debtors also will be dependent on expected disbursements from foreign governments or multinational agencies and the country’s access to, or balance of, trade. Some governmental debtors have in the past been able to reschedule or restructure their debt payments without the approval of debt holders or declare moratoria on payments, and similar occurrences may happen in the future. There is no bankruptcy proceeding by which a Fund may collect in whole or in part on debt subject to default by a government.

Foreign currency exchange rates. Changes in foreign currency exchange rates will affect the US dollar market value of securities denominated in such foreign currencies and any income received or expenses paid by a Fund in that foreign currency. This may affect a Fund’s share price, income, and distributions to shareholders. Some countries may have fixed or managed currencies that are not free-floating against the US dollar. It will be more difficult for the Manager to value securities denominated in currencies that are fixed or managed. Certain currencies may not be internationally traded, which could cause illiquidity with respect to a Fund’s investments in that currency and any securities denominated in that currency. Currency markets generally are not as regulated as securities markets. A Fund endeavors to buy and sell foreign currencies on as favorable a basis as practicable. Some price spread in currency exchanges (to cover service charges) may be incurred, particularly when a Fund changes investments from one country to another or when proceeds of the sale of securities in US dollars are used for the purchase of securities denominated in foreign currencies. Some countries may adopt policies that would prevent a Fund from transferring cash out of the country or withhold portions of interest and dividends at the source.

Certain currencies have experienced a steady devaluation relative to the US dollar. Any devaluations in the currencies in which a Fund’s portfolio securities are denominated may have a detrimental impact on the Fund. Where the exchange rate for a currency declines materially after a Fund’s income has been accrued and translated into US dollars, the Fund may need to redeem portfolio securities to make required distributions. Similarly, if an exchange rate declines between the time the Fund incurs expenses in US dollars and the time such expenses are paid, a Fund will have to convert a greater amount of the currency into US dollars in order to pay the expenses.

Investing in foreign currencies for purposes of gaining from projected changes in exchange rates further increases a Fund’s exposure to foreign securities losses.

The Funds do not consider currencies or other financial commodities or contracts and financial instruments to be physical commodities (which include, for example, oil, precious metals, and grains). Accordingly, the Funds interpret the fundamental restriction related to commodities to permit it (subject to its investment goals and general investment policies) to invest directly in foreign currencies and other financial commodities and to purchase, sell, or enter into foreign currency futures contracts and options thereon, forward foreign currency contracts, foreign currency options, currency, commodity- and financial instrument-related swap agreements, hybrid instruments, interest rate, securities-related or foreign currency-related futures contracts or other currency-, commodity- or financial instrument-related derivatives, subject to compliance with any applicable provisions of the federal securities or commodities laws. The Funds also interpret their fundamental restriction regarding purchasing and selling physical commodities to permit the Funds to invest in exchange-traded funds (“ETFs”) or other entities that invest in physical and/or financial commodities.

China A-shares and Bond Connect. The Funds may invest in China A-shares of certain Chinese companies listed and traded on the Shanghai Stock Exchange and on the Shenzhen Stock Exchange (together, the “Exchanges”) through the Shanghai-Hong Kong Stock Connect Program and the

Shenzhen-Hong Kong Stock Connect Program, respectively (together, “Stock Connect”). Stock Connect is a securities trading and clearing program developed by the Exchange of Hong Kong, the Exchanges and the China Securities Depository and Clearing Corporation Limited. Stock Connect facilitates foreign investment in the People’s Republic of China (“PRC”) via brokers in Hong Kong. The Funds may also invest in China Interbank bonds traded on the China Interbank Bond Market (“CIBM”) through the China ‑ Hong Kong Bond Connect program (“Bond Connect”). Bond Connect enables foreign investors to access the CIBM ‑ which represents over 85% of Chinese onshore bonds ‑ with greater ease by establishing a trading and settlement link between the mainland and established Hong Kong financial infrastructure institutions.  Investing in Chinese securities presents various risks including relatively volatile local markets, a volatile currency, potentially lower liquidity and greater government intervention. Persons investing through Stock Connect or Bond Connect are subject to PRC regulations and Exchange listing rules, among others. These could include limitations on or suspension of trading. These regulations are relatively new and subject to changes which could adversely impact a Fund’s rights with respect to the securities. As Stock Connect and Bond Connect are relatively new, there are no assurances that the necessary systems to run the program will function properly. Stock Connect is subject to aggregate and daily quota limitations on purchases and a Fund may experience delays in transacting via Stock Connect. Purchases of bonds via Bond Connect will require pre-funding and there is settlement risk due to the limited capability to cancel trades.

Forward Contracts

A forward contract is an agreement between two parties in which one party is obligated to deliver a stated amount of a stated asset at a specified time in the future and the other party is obligated to pay a specified amount for the assets at the time of delivery. A Fund may enter into forward contracts to purchase and sell government securities, equity or income securities, foreign currencies or other financial instruments. Forward contracts generally are traded in an interbank market conducted directly between traders (usually large commercial banks) and their customers. Unlike futures contracts, which are standardized contracts, forward contracts can be specifically drawn to meet the needs of the parties that enter into them. The parties to a forward contract may agree to offset or terminate the contract before its maturity, or may hold the contract to maturity and complete the contemplated exchange.

A Fund will cover outstanding forward contracts by maintaining liquid portfolio securities in an amount not less than the value of that Fund’s total assets committed to the consummation of such contracts. To the extent that a Fund is not able to cover its forward positions with underlying portfolio securities, the Fund’s custodian will segregate cash or other liquid assets having a value equal to the aggregate amount of such Fund’s commitments under forward contracts entered into with respect to position hedges, cross-hedges and anticipatory hedges. If the value of the securities used to cover a position or the value of segregated assets declines, a Fund will find alternative cover or segregate additional cash or liquid assets on a daily basis so that the value of the covered and segregated assets will be equal to the amount of such Fund’s commitments with respect to such contracts.

Forward Foreign Currency Contracts

A Fund may purchase or sell currencies and/or engage in forward foreign currency contracts (i.e., contracts to exchange one currency for another on some future date at a specified exchange rate) in order to expedite settlement of portfolio transactions in connection with its investment in foreign securities and to minimize currency value fluctuations. Forward foreign currency contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A forward foreign currency contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A Fund will account for forward foreign currency contracts by marking to market each day at daily exchange rates.

The Funds value their assets daily in US dollars, but do not intend to convert the value of their foreign holdings into US dollars on a daily basis. The Funds will, however, from time to time, purchase or sell foreign currencies and/or engage in forward foreign currency contracts in order to facilitate or expedite settlement of Fund transactions and to minimize currency value fluctuations. The Funds may conduct their forward foreign currency contracts on a spot (i.e., cash) basis at the spot rate prevailing in the foreign currency exchange market or through entering into contracts to purchase or sell foreign currencies at a future date (i.e., a “forward foreign currency” contract or “forward” contract), and investors should be aware of the costs of currency conversion.

When a Fund enters into a contract for the purchase or sale of a security denominated in a foreign currency, or when it anticipates the receipt in a foreign currency of dividends or interest payments on a security that it holds, the Fund may desire to “lock in” the US dollar price of the security or the US dollar equivalent of such dividend or interest payment as the case may be. By entering into a forward contract for a fixed amount of dollars for the purchase or sale of the amount of foreign currency involved in the underlying transactions, a Fund will be able to protect itself against a possible loss resulting from an adverse change in the relationship between the US dollar and the subject foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

Additionally, when the Manager believes that the currency of a particular foreign country may suffer a substantial decline against the US dollar, a Fund may enter into a forward foreign currency contract for a fixed amount of dollars, to sell the amount of foreign currency approximating the value of some or all of the securities of the Fund denominated in such foreign currency.

The Funds may use forward foreign currency contracts to manage currency risks and to facilitate transactions in foreign securities. The following discussion summarizes the principal currency management strategies involving forward foreign currency contracts that could be used by the Funds.

In connection with purchases and sales of securities denominated in foreign currencies, the Funds may enter into forward foreign currency contracts to fix a definite price for the purchase or sale in advance of the trade’s settlement date. This technique is sometimes referred to as a “settlement hedge” or “transaction hedge.” The Manager expects to enter into settlement hedges in the normal course of managing the Funds’ foreign investments. A Fund could also enter into forward foreign currency contracts to purchase or sell a foreign currency in anticipation of future purchases or sales of securities denominated in a foreign currency, even if the specific investments have not yet been selected by the Manager.

The Funds may also use forward foreign currency contracts to hedge against a decline in the value of existing investments denominated in a foreign currency. For example, if a Fund owned securities denominated in pounds sterling, it could enter into a forward foreign currency contract to sell pounds sterling in return for US dollars to hedge against possible declines in the pound’s value. Such a hedge (sometimes referred to as a “position hedge”) would tend to offset both positive and negative currency fluctuations, but would not offset changes in security values caused by other factors. A Fund could also hedge the position by selling another currency expected to perform similarly to the pound sterling — for example, by entering into a forward foreign currency contract to sell euros in return for US dollars. This type of hedge, sometimes referred to as a “proxy hedge,” could offer advantages in terms of cost, yield, or efficiency, but generally will not hedge currency exposure as effectively as a simple hedge into US dollars. Proxy hedges may result in losses if the currency used to hedge does not perform similarly to the currency in which the hedged securities are denominated.

Under definitions adopted by the CFTC and the SEC, nondeliverable forwards are considered swaps, and therefore are included in the definition of “commodity interests.” A nondeliverable forward is a cash-settled, short-term forward foreign currency contract on a thinly traded or nonconvertible foreign currency, where the profit or loss at the time of the settlement date is calculated by taking the difference between the agreed upon exchange rate and the spot rate at the time of settlement, for an agreed upon notional amount of funds. Although nondeliverable forwards have historically been traded in the over-the-counter (“OTC”) market, as swaps they may in the future be required to be centrally cleared and traded on public facilities. Currency and cross currency forwards that qualify as deliverable forwards are not regulated as swaps for most purposes, and are not included in the definition of “commodity interests.” However these forwards are subject to some requirements applicable to swaps, including reporting to swap data repositories, documentation requirements, and business conduct rules applicable to swap dealers.

Risks of forward foreign currency contracts. The successful use of these transactions will usually depend on the Manager’s ability to accurately forecast currency exchange rate movements. Should exchange rates move in an unexpected manner, a Fund may not achieve the anticipated benefits of the transaction, or it may realize losses. In addition, these techniques could result in a loss if the counterparty to the transaction does not perform as promised, for example, due to bankruptcy or insolvency of the counterparty. While a Fund uses only counterparties that meet its credit quality standards, in unusual or extreme market conditions, a counterparty’s creditworthiness and ability to perform may deteriorate rapidly, and the availability of suitable replacement counterparties may become limited. Moreover, investors should bear in mind that a Fund is not obligated to actively engage in hedging or other currency transactions. For example, a Fund may not attempt to hedge its exposure to a particular foreign currency at a time when doing so might avoid a loss.

Forward foreign currency contracts may limit potential gain from a positive change in the relationship between the US dollar and foreign currencies. Unanticipated changes in currency prices may result in poorer overall performance for a Fund than if it had not engaged in such contracts. Moreover, there may be an imperfect correlation between a Fund’s portfolio holdings of securities denominated in a particular currency and the currencies bought or sold in the forward foreign currency contracts entered into by the Fund. This imperfect correlation may cause a Fund to sustain losses that will prevent the Fund from achieving a complete hedge or expose the Fund to risk of foreign exchange loss.

Futures and Options on Futures

A Fund may enter into futures contracts relating to securities, securities indices, interest rates and currencies. Futures, a type of potentially high-risk derivatives, are often used to manage or hedge risk because they enable the investor to buy or sell an asset in the future at an agreed-upon price. Futures contracts may be bought or sold for any number of reasons, including: to manage a Fund’s exposure to changes in securities prices and foreign currencies; as an efficient means of adjusting a Fund’s overall exposure to certain markets; in an effort to enhance income; to protect the value of portfolio securities; and as a cash management tool. Futures contracts may not always be successful hedges; their prices can be highly volatile; using them could lower a Fund’s total return; and the potential loss from the use of futures can exceed a Fund’s initial investment in such contracts.

Purchases or sales of stock or bond index futures contracts are used for hedging purposes to attempt to protect a Fund’s current or intended investments from broad fluctuations in stock or bond prices. When a Fund is not fully invested in the securities market and anticipates a significant market advance, it may purchase stock or bond index futures contracts in order to gain rapid market exposure that may, in part or entirely, offset increases in the cost of securities that the Fund intends to purchase.

Interest rate futures contracts are purchased or sold for hedging purposes to attempt to protect against the effects of interest rate changes on a Fund’s current or intended investments in fixed income securities. However, since the futures market is more liquid than the cash market, the use of interest rate futures contracts as a hedging technique allows a Fund to hedge its interest rate risk without having to sell its portfolio securities.

A Fund may purchase and sell foreign currency futures contracts for hedging purposes to attempt to protect current or intended investments from fluctuations in currency exchange rates. A Fund also may engage in currency “cross hedging” when, in the opinion of the investment adviser, the historical relationship among foreign currencies suggests that the Fund may achieve protection against fluctuations in currency exchange rates similar to that described above at a reduced cost through the use of a futures contract relating to a currency other than the US dollar or the currency in which the foreign security is denominated. Such “cross hedging” is subject to the same risks as those described above with respect to an unanticipated increase or decline in the value of the subject currency relative to the dollar.

A Fund may purchase and write options on the types of futures contracts in which each Fund may invest. The writing of a call option on a futures contract constitutes a partial hedge against declining prices of the securities in a Fund’s portfolio. The writing of a put option on a futures contract constitutes a partial hedge against increasing prices of the securities or other instruments required to be delivered under the terms of the futures contract. A Fund may purchase options on futures contracts for hedging purposes instead of purchasing or selling the underlying futures contracts.

A Fund also may make investments in Eurodollar instruments. Eurodollar instruments are US dollar-denominated futures contracts or options thereon that are linked to the London Interbank Offered Rate (“LIBOR”), although foreign currency-denominated instruments are available from time to time. Eurodollar futures contracts enable purchasers to obtain a fixed rate for the lending of funds and sellers to obtain a fixed rate for borrowings. A Fund might use Eurodollar futures contracts and options thereon to hedge against changes in LIBOR, to which many interest rate swaps and fixed income instruments are linked. For more information on risks related to LIBOR, please see “LIBOR Transition Risk” in this section.

Futures contracts. Generally, a futures contract is a standard binding agreement to buy or sell a specified quantity of an underlying reference instrument, such as a specific security, currency or commodity, at a specified price at a specified later date. A “sale” of a futures contract means the acquisition of a contractual obligation to deliver the underlying reference instrument called for by the contract at a specified price on a specified date. A “purchase” of a futures contract means the acquisition of a contractual obligation to acquire the underlying reference instrument called for by the contract at a specified price on a specified date. The purchase or sale of a futures contract will allow a Fund to increase or decrease its exposure to the underlying reference instrument without having to buy the actual instrument.

The underlying reference instruments to which futures contracts may relate include non-US currencies, interest rates, stock and bond indices, and debt securities, including US government debt obligations. In most cases the contractual obligation under a futures contract may be offset, or “closed out,” before the settlement date so that the parties do not have to make or take delivery. The closing out of a contractual obligation is usually accomplished by buying or selling, as the case may be, an identical, offsetting futures contract. This transaction, which is effected through a member of an exchange, cancels the obligation to make or take delivery of the underlying instrument or asset. Although some futures contracts by their terms require the actual delivery or acquisition of the underlying instrument or asset, some require cash settlement.

Futures contracts may be bought and sold on US and non-US exchanges. Futures contracts in the US have been designed by exchanges that have been designated “contract markets” by the Commodity Futures Trading Commission (“CFTC”) and must be executed through a futures commission merchant (“FCM”), which is a brokerage firm that is a member of the relevant contract market. Each exchange guarantees performance of the contracts as between the clearing members of the exchange, thereby reducing the risk of counterparty default. Futures contracts may also be entered into on certain exempt markets, including exempt boards of trade and electronic trading facilities, available to certain market participants. Because all transactions in the futures market are made, offset, or fulfilled by an FCM through a clearinghouse associated with the exchange on which the contracts are traded, a Fund will incur brokerage fees when it buys or sells futures contracts.

The Funds generally buy and sell futures contracts only on contract markets (including exchanges or boards of trade) where there appears to be an active market for the futures contracts, but there is no assurance that an active market will exist for any particular contract or at any particular time. An active market makes it more likely that futures contracts will be liquid and bought and sold at competitive market prices. In addition, many of the futures contracts available may be relatively new instruments without a significant trading history. As a result, there can be no assurance that an active market will develop or continue to exist.

When a Fund enters into a futures contract, it must deliver to an account controlled by the FCM (that has been selected by the Fund), an amount referred to as “initial margin” that is typically calculated as an amount equal to the volatility in the market value of a contract over a fixed period. Initial margin requirements are determined by the respective exchanges on which the futures contracts are traded and the FCM. Thereafter, a “variation margin” amount may be required to be paid by a Fund or received by the Fund in accordance with margin controls set for such accounts, depending upon changes in the marked-to-market value of the futures contract. The account is marked-to-market daily and the variation margin is monitored by the Manager and the Funds’ custodian on a daily basis. When the futures contract is closed out, if a Fund has a loss equal to or greater than the margin amount, the margin amount is paid to the FCM along with any loss in excess of the margin amount. If a Fund has a loss of less than the margin amount, the excess margin is returned to the Fund. If a Fund has a gain, the full margin amount and the amount of the gain is paid to the Fund.

Some futures contracts provide for the delivery of securities that are different than those that are specified in the contract. For a futures contract for delivery of debt securities, on the settlement date of the contract, adjustments to the contract can be made to recognize differences in value arising from the delivery of debt securities with a different interest rate from that of the particular debt securities that were specified in the contract. In some cases, securities called for by a futures contract may not have been issued when the contract was written.

Risks of futures contracts. The Funds’ use of futures contracts is subject to the risks associated with derivatives instruments generally. In addition, a purchase or sale of a futures contract may result in losses to a Fund in excess of the amount that the Fund delivered as initial margin. Because of the relatively low margin deposits required, futures trading involves a high degree of leverage; as a result, a relatively small price movement in a futures contract may result in immediate and substantial loss, or gain, to a Fund. In addition, if a Fund has insufficient cash to meet daily variation margin requirements or close out a futures position, it may have to sell securities from its portfolio at a time when it may be disadvantageous to do so. Adverse market movements could cause a Fund to experience substantial losses on an investment in a futures contract.

There is a risk of loss by a Fund of the initial and variation margin deposits in the event of bankruptcy of the FCM with which the Fund has an open position in a futures contract. The assets of a Fund may not be fully protected in the event of the bankruptcy of the FCM or central counterparty because the Fund might be limited to recovering only a pro rata share of all available funds and margin segregated on behalf of an FCM’s customers. If the FCM does not provide accurate reporting, a Fund is also subject to the risk that the FCM could use the Fund’s assets, which are held in an omnibus account with assets belonging to the FCM’s other customers, to satisfy its own financial obligations or the payment obligations of another customer to the central counterparty.

A Fund may not be able to properly hedge or effect its strategy when a liquid market is unavailable for the futures contract the Fund wishes to close, which may at times occur. In addition, when futures contracts are used for hedging, there may be an imperfect correlation between movements in the prices of the underlying reference instrument on which the futures contract is based and movements in the prices of the assets sought to be hedged.

If the Manager’s investment judgment about the general direction of market prices or interest or currency exchange rates is incorrect, a Fund’s overall performance will be poorer than if it had not entered into a futures contract. For example, if a Fund has purchased futures to hedge against the possibility of an increase in interest rates that would adversely affect the price of bonds held in its portfolio and interest rates instead decrease, the Fund will lose part or all of the benefit of the increased value of the bonds which it has hedged. This is because its losses in its futures positions will offset some or all of its gains from the increased value of the bonds.

The difference (called the “spread”) between prices in the cash market for the purchase and sale of the underlying reference instrument and the prices in the futures market is subject to fluctuations and distortions due to differences in the nature of those two markets. First, all participants in the futures market are subject to initial deposit and variation margin requirements. Rather than meeting additional variation margin requirements, investors may close futures contracts through offsetting transactions that could distort the normal pricing spread between the cash and futures markets. Second, the liquidity of the futures markets depends on participants entering into offsetting transactions rather than making or taking delivery of the underlying instrument. To the extent participants decide to make or take delivery, liquidity in the futures market could be reduced, resulting in pricing distortion. Third, from the point of view of speculators, the margin deposit requirements that apply in the futures market are less onerous than similar margin requirements in the securities market. Therefore, increased participation by speculators in the futures market may cause temporary price distortions. When such distortions occur, a correct forecast of general trends in the price of an underlying reference instrument by the Manager may still not necessarily result in a profitable transaction.

Futures contracts that are traded on non-US exchanges may not be as liquid as those purchased on CFTC-designated contract markets. In addition, non-US futures contracts may be subject to varied regulatory oversight. The price of any non-US futures contract and, therefore, the potential profit and loss thereon, may be affected by any change in the non-US exchange rate between the time a particular order is placed and the time it is liquidated, offset or exercised.

The CFTC and the various exchanges have established limits referred to as “speculative position limits” on the maximum net long or net short position that any person, such as a Fund, may hold or control in a particular futures contract. Trading limits are also imposed on the maximum number of contracts that any person may trade on a particular trading day. An exchange may order the liquidation of positions found to be in violation of these limits and it may impose other sanctions or restrictions. The regulation of futures, as well as other derivatives, is a rapidly changing area of law.

Futures exchanges may also limit the amount of fluctuation permitted in certain futures contract prices during a single trading day. This daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price. Once the daily limit has been reached in a futures contract subject to the limit, no more trades may be made on that day at a price beyond that limit. The daily limit governs only price movements during a particular trading day and does not limit potential losses because the limit may prevent the liquidation of unfavorable positions. For example, futures prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of positions and subjecting some holders of futures contracts to substantial losses.

Options on futures contracts. Options on futures contracts trade on the same contract markets as the underlying futures contract. When a fund buys an option, it pays a premium for the right, but does not have the obligation, to purchase (call) or sell (put) a futures contract at a set price (called the exercise price). The purchase of a call or put option on a futures contract, whereby the Fund has the right to purchase or sell, respectively, a particular futures contract, is similar in some respects to the purchase of a call or put option on an individual security or currency. Depending on the premium paid for the option compared to either the price of the futures contract upon which it is based or the price of the underlying reference instrument, the option may be less risky than direct ownership of the futures contract or the underlying reference instrument. For example, a fund could purchase a call option on a long futures contract when seeking to hedge against an increase in the market value of the underlying reference instrument, such as appreciation in the value of a non-US currency against the US dollar.

The seller (writer) of an option becomes contractually obligated to take the opposite futures position if the buyer of the option exercises its rights to the futures position specified in the option. In return for the premium paid by the buyer, the seller assumes the risk of taking a possibly adverse futures position. In addition, the seller will be required to post and maintain initial and variation margin with the FCM. One goal of selling (writing) options on futures may be to receive the premium paid by the option buyer.

For more general information about the mechanics of purchasing and writing options, see “Options” below.

Risks of options on futures contracts. A Fund’s use of options on futures contracts is subject to the risks related to derivatives instruments generally. In addition, the amount of risk a Fund assumes when it purchases an option on a futures contract is the premium paid for the option plus related transaction costs. The purchase of an option also entails the risk that changes in the value of the underlying futures contract will not be fully reflected in the value of the option purchased. The seller (writer) of an option on a futures contract is subject to the risk of having to take a possibly adverse futures position if the purchaser of the option exercises its rights. If the seller were required to take such a position, it could bear substantial losses. An option writer has potentially unlimited economic risk because its potential loss, except to the extent offset by the premium received, is equal to the amount the option is “in-the-money” at the expiration date. A call option is in-the-money if the value of the underlying futures contract exceeds the exercise price of the option. A put option is in-the-money if the exercise price of the option exceeds the value of the underlying futures contract.

High Yield Securities (“Junk bonds”)

High yield, high risk securities are commonly known as “junk bonds.” These securities are rated lower than BBB- by S&P, lower than Baa3 by Moody’s, or similarly rated by another nationally recognized statistical rating organization (“NRSRO”), or, if unrated, determined by the Manager or the Sub-advisor to be of comparable quality. Along with securities of distressed companies, junk bonds are often considered to be speculative and involve significantly higher risk of default on the payment of principal and interest or are more likely to experience significant price fluctuation due to changes in the issuer’s creditworthiness. Market prices of these securities may fluctuate more than higher-rated debt securities and may decline significantly in periods of general economic difficulty, which may follow periods of rising interest rates. Securities of distressed companies include both debt and equity securities. Issuers of lower-rated and distressed company securities may be involved in restructurings or bankruptcy proceedings that may not be successful. Although the market for high yield corporate debt securities and securities of distressed companies has been in existence for many years and has weathered previous economic downturns, the market in recent years has experienced a dramatic increase in the large-scale use of such securities to fund highly leveraged corporate acquisitions and restructurings. Accordingly, past experience may not provide an accurate indication of future performance of the high yield bond market, especially during periods of economic recession. See “Appendix A—Description of Ratings.”

The market for lower-rated securities and debt securities of distressed companies may be less active than that for higher-rated securities, which can adversely affect the prices at which these securities can be sold. If market quotations are not available, these securities will be valued in accordance with procedures established by the Board, including the use of outside pricing services. Judgment plays a greater role in valuing high yield corporate debt securities than is the case for securities for which more external sources for quotations and last-sale information are available. Adverse publicity and changing investor perceptions may affect the ability of outside pricing services used by a Fund to value its portfolio securities and the Fund’s ability to dispose of these lower-rated debt securities.

Since the risk of default is higher for lower-quality securities, the research and credit analysis of the portfolio manager(s) are an integral part of managing any securities of this type. In considering junk bond investments, the portfolio manager(s) will attempt to identify those issuers of high yielding securities whose financial conditions are adequate to meet future obligations, have improved, or are expected to improve in the future. The analysis of the portfolio manager(s) focuses on relative values based on such factors as interest or dividend coverage, asset coverage, earnings prospects, and the experience and managerial strength of the issuer. There can be no assurance that such analysis will prove accurate.

A Fund may choose, at its expense or in conjunction with others, to pursue litigation or otherwise exercise its rights as security holder to seek to protect the interests of security holders if it determines this to be in the best interest of shareholders.

Hybrid Instruments

Hybrid instruments (a type of potentially high-risk derivative) that the Funds may invest in have been developed and combine the elements of futures contracts or options with those of debt, preferred equity, or a depository instrument (hereinafter “hybrid instruments”). Generally, a hybrid instrument will be a debt security, preferred stock, depository share, trust certificate, certificate of deposit, or other evidence of indebtedness on which a portion of or all interest payments, and/or the principal or stated amount payable at maturity, redemption, or retirement is determined by reference to prices, changes in prices, or differences between prices of securities, currencies, intangibles, goods, articles, or commodities (collectively “underlying assets”) or by another objective index, economic factor, or other measure, such as interest rates, currency exchange rates, commodity indices, and securities indices (collectively “benchmarks”). Thus, hybrid instruments may take a variety of forms, including, but not limited to, debt instruments with interest or principal payments or redemption terms determined by reference to the value of a currency or commodity or securities index at a future point in time, preferred stock with dividend rates determined by reference to the value of a currency, or convertible securities with the conversion terms related to a particular commodity.

Hybrid instruments can be efficient means of creating exposure to a particular market, or segment of a market, with the objective of enhancing total return. For example, a Fund may wish to take advantage of expected declines in interest rates in several European countries, but avoid the transaction costs associated with buying and currency-hedging the foreign bond positions. One solution would be to purchase a US dollar-denominated hybrid instrument whose redemption price is linked to the average 3-year interest rate in a designated group of countries. The redemption price formula would provide for payoffs of greater than par if the average interest rate were lower than a specified level, and payoffs of less than par if rates were above the specified level. Furthermore, a Fund could limit the downside risk of the security by establishing a minimum redemption price so that the principal paid at maturity could not be below a predetermined minimum level if interest rates were to rise significantly. The purpose of this arrangement, known as a structured security with an embedded put option, would be to give the Fund the desired European bond exposure while avoiding currency risk, limiting downside market risk, and lowering transaction costs. Of course, there is no guarantee that the strategy will be successful, and a Fund could lose money if, for example, interest rates do not move as anticipated or credit problems develop with the issuer of the hybrid instruments.

The risks of investing in hybrid instruments reflect a combination of the risks of investing in securities, options, futures, and currencies. Thus, an investment in a hybrid instrument may entail significant risks that are not associated with a similar investment in a traditional debt instrument that has a fixed principal amount, is denominated in US dollars, or bears interest either at a fixed rate or a floating rate determined by reference to a common, nationally published benchmark. The risks of a particular hybrid instrument will, of course, depend upon the terms of the instrument, but may include, without limitation, the possibility of significant changes in the benchmarks or the prices of underlying assets to which the instrument is linked. Such risks generally depend upon factors that are unrelated to the operations or credit quality of the issuer of the hybrid instrument and that may not be readily foreseen by the purchaser, such as economic and political events, the supply of and demand for the underlying assets, and interest rate movements. In recent years, various benchmarks

and prices for underlying assets have been highly volatile, and such volatility may be expected in the future. Reference is also made to the discussion of futures, options, and forward contracts herein for a discussion of the risks associated with such investments.

Hybrid instruments are potentially more volatile and carry greater market risks than traditional debt instruments. Depending on the structure of the particular hybrid instrument, changes in a benchmark may be magnified by the terms of the hybrid instrument and have an even more dramatic and substantial effect upon the value of the hybrid instrument. Also, the prices of the hybrid instrument and the benchmark or underlying asset may not move in the same direction or at the same time.

Hybrid instruments may bear interest or pay preferred dividends at below market (or even relatively nominal) rates. Alternatively, hybrid instruments may bear interest at above market rates but bear an increased risk of principal loss (or gain). The latter scenario may result if “leverage” is used to structure the hybrid instrument. Leverage risk occurs when the hybrid instrument is structured so that a given change in a benchmark or underlying asset is multiplied to produce a greater value change in the hybrid instrument, thereby magnifying the risk of loss as well as the potential for gain.

Hybrid instruments may also carry liquidity risk since the instruments are often “customized” to meet the portfolio needs of a particular investor and, therefore, the number of investors that are willing and able to buy such instruments in the secondary market may be smaller than that for more traditional debt securities. In addition, because the purchase and sale of hybrid instruments could take place in an over-the-counter market without the guarantee of a central clearing organization or in a transaction between a Fund and the issuer of the hybrid instrument, the creditworthiness of the counterparty or issuer of the hybrid instrument would be an additional risk factor, which the Fund would have to consider and monitor. Hybrid instruments also may not be subject to regulation by the CFTC, which generally regulates the trading of commodity futures by US persons, the SEC, which regulates the offer and sale of securities by and to US persons, or any other governmental regulatory authority.

The various risks discussed above, particularly the market risk of such instruments, may in turn cause significant fluctuations in the NAV of a Fund.

Illiquid and Restricted Investments

Each Fund is permitted to invest up to 15% of its respective net assets in illiquid investments. For purposes of a Fund’s 15% limitation, illiquid investment means any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment, as determined pursuant to the 1940 Act and applicable rules and regulations thereunder. Illiquid investments, for purposes of this policy, include repurchase agreements maturing in more than seven calendar days.

Illiquid investments, for purposes of this policy, include repurchase agreements maturing in more than seven calendar days. Each Fund may purchase privately placed debt and other securities whose resale is restricted under applicable securities laws. Each Fund may invest in restricted securities, including securities eligible for resale without registration pursuant to Rule 144A (“Rule 144A Securities”) under the 1933 Act. Rule 144A exempts many privately placed and legally restricted securities from the registration requirements of the 1933 Act and permits such securities to be freely traded among certain institutional buyers such as the Funds. Restricted securities generally offer a higher return potential than comparable registered securities but involve some additional risk since they can be resold only in privately negotiated transactions or after registration under applicable securities laws. The registration process may involve delays which would result in a Fund obtaining a less favorable price on a resale.

The Manager is responsible for the day-to-day functions of determining whether or not individual Rule 144A Securities are liquid for purposes of a Fund’s limitation on investments in illiquid investments. The Manager considers the following factors in determining the liquidity of a Rule 144A Security: (i) the frequency of trades and trading volume for the security; (ii) whether at least three dealers are willing to purchase or sell the security and the number of potential purchasers; (iii) whether at least two dealers are making a market in the security; and (iv) the nature of the security and the nature of the marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer).

If the Manager determines that a Rule 144A Security which was previously determined to be liquid is no longer liquid and, as a result, a Fund’s holdings of illiquid investments exceed its limit on investment in such investments, the Manager will determine what action shall be taken to ensure that the Fund continues to adhere to such limitation.

Initial Public Offerings

Under certain market conditions, a Fund may invest in a company at the time of its initial public offering (IPO).

Companies involved in IPOs generally have limited operating histories, and prospects for future profitability are uncertain. Prices of IPOs may also be unstable because of the absence of a prior public market, the small number of shares available for trading, and limited investor information. IPOs may be sold within 12 months of purchase. This may result in increased short-term capital gains, which will be taxable to shareholders as ordinary income.

Inverse Floaters

Inverse floaters are debt instruments whose interest bears an inverse relationship to the interest rate on another security. The prices of inverse floaters can be considerably more volatile than the prices of bonds with comparable maturities.

Investment Companies

Each Fund may invest in other investment companies to the extent permitted by the 1940 Act, SEC rules thereunder and exemptions thereto.

With respect to unaffiliated funds in which a Fund may invest, Section 12(d)(1)(A) of the 1940 Act requires that, as determined immediately after a purchase is made, (i) not more than 5% of the value of the Fund’s total assets will be invested in the securities of any one investment company, (ii) not more than 10% of the value of the Fund’s total assets will be invested in securities of investment companies as a group, and (iii) not more than 3% of the outstanding voting stock of any one investment company will be owned by the Fund. A Fund will limit its investments in unaffiliated funds in accordance with the Section 12(d)(1)(A) limitations set forth above, except to the extent that any rules, regulations or no-action or exemptive relief under the 1940 Act permit the Fund’s investments to exceed such limits in unaffiliated underlying funds. To the extent that a Fund invests in another investment company, because other investment companies pay advisory, administrative and service fees that are borne indirectly by investors, such as the Fund, there may be duplication of investment management and other fees.

Each Fund may invest in securities issued by closed-end funds, subject to any of its investment policies. If a Fund invests in shares issued by leveraged closed-end funds, it will face certain risks associated with leveraged investments. Investments in closed-end funds are subject to additional risks. For example, the price of the closed-end fund’s shares quoted on an exchange may not reflect the NAV of the securities held by the closed-end fund, and the premium or discount the share prices represent versus NAV may change over time based on a variety of factors, including supply of and demand for the closed-end fund’s shares, that are outside the closed-end fund’s control or unrelated to the value of the underlying portfolio securities. If a Fund invests in the closed-end fund to gain exposure to the closed-end fund’s investments, the lack of correlation between the performance of the closed-end fund’s investments and the closed-end fund’s share price may compromise or eliminate any such exposure.

To the extent that a Fund invests in an ETF, the market value of the ETF shares may differ from their NAV because the supply and demand in the market for ETF shares at any point in time is not always identical to the supply and demand in the market for the underlying securities. Also, ETFs that track particular indices typically will be unable to match the performance of the index exactly due to the ETFs’ operating expenses and transaction costs.

Also, ETFs that track particular indices typically will be unable to match the performance of the index exactly due to the ETFs’ operating expenses and transaction costs.

Loans and Other Indebtedness

Each Fund may purchase loans and other indebtedness. 

In purchasing a loan, a Fund acquires some or all of the interest of a bank or other lending institution in a loan to a corporate, governmental or other borrower. Many such loans are secured, although some may be unsecured. Such loans may be in default at the time of purchase. Loans that are fully secured offer a Fund more protection than an unsecured loan in the event of nonpayment of scheduled interest or principal. However, there is no assurance that the liquidation of collateral from a secured loan would satisfy the corporate borrower’s obligation, or that the collateral can be liquidated. These loans are made generally to finance internal growth, mergers, acquisitions, stock repurchases, leveraged buy-outs, and other corporate activities. Such loans are typically made by a syndicate of lending institutions, represented by an agent lending institution that has negotiated and structured the loan and is responsible for collecting interest, principal, and other amounts due on its own behalf and on behalf of the others in the syndicate, and for enforcing its and their other rights against the borrower. Alternatively, such loans may be structured as a novation, pursuant to which a Fund would assume all of the rights of the lending institution in a loan or as an assignment, pursuant to which a Fund would purchase an assignment of a portion of a lender’s interest in a loan either directly from the lender or through an intermediary.

A Fund may also purchase trade or other claims against companies, which generally represent money owed by the company to a supplier of goods or services. These claims may also be purchased at a time when the company is in default.

Certain of the loans and the other indebtedness acquired by a Fund may involve revolving credit facilities or other standby financing commitments which obligate a Fund to pay additional cash on a certain date or on demand. These commitments may require a Fund to increase its investment in a company at a time when the Fund might not otherwise decide to do so (including at a time when the company’s financial condition makes it unlikely that such amounts will be repaid). A Fund’s ability to receive payment of principal, interest, and other amounts due in connection with these investments will depend primarily on the financial condition of the borrower. In selecting the loans and other indebtedness that a Fund will purchase, the Manager will rely upon its own (and not the original lending institution’s) credit analysis of the borrower. As a Fund may be required to rely upon another lending institution to collect and pass onto the Fund amounts payable with respect to the loan and to enforce the Fund’s rights under the loan and other indebtedness, an insolvency, bankruptcy, or reorganization of the lending institution may delay or prevent the Fund from receiving such amounts. In such cases, a Fund will evaluate as well the creditworthiness of the lending institution and will treat both the borrower and the lending institution as an “issuer” of the loan for purposes of compliance with applicable law pertaining to the diversification of the Fund’s portfolio investments. The highly leveraged nature of many such loans and other indebtedness may make such loans and other indebtedness especially vulnerable to adverse changes in economic or market conditions. Investments in such loans and other indebtedness may involve additional risk to a Fund.

Master Limited Partnerships (“MLPs”)

The Funds may invest in MLPs. An MLP is a publicly traded company organized as a limited partnership or limited liability company and treated as a partnership for federal income tax purposes.

MLPs may derive income and gains from the exploration, development, mining or production, processing, refining, transportation (including pipelines transporting gas, oil, or products thereof), or the marketing of any mineral or natural resources. MLPs generally have two classes of owners, the general partner and limited partners. When investing in an MLP, a Fund intends to purchase publicly traded common units issued to limited partners of the MLP. The general partner of an MLP is typically owned by one or more of the following: a major energy company, an investment fund, or the direct management of the MLP. The general partner may be structured as a private or publicly traded corporation or other entity. The general partner typically controls the operations and management of the MLP through an up to 2% equity interest in the MLP plus, in many cases, ownership of common units and subordinated units. Limited partners own the remainder of the partnership, through ownership of common units, and have a limited role in the partnership’s operations and management.

MLPs combine the tax advantages of a partnership with the liquidity of a publicly traded stock. MLP income is generally not subject to entity-level tax. Instead, an MLP’s income, gain, loss, deductions and other tax items pass through to common unitholders.

MLPs are typically structured such that common units and general partner interests have first priority to receive quarterly cash distributions up to an established minimum amount (“minimum quarterly distributions” or “MQD”). Common and general partner interests also accrue arrearages in distributions to the extent the MQD is not paid. Once common and general partner interests have been paid, subordinated units receive distributions of up to the MQD; however, subordinated units do not accrue arrearages. Distributable cash in excess of the MQD paid to both common and subordinated units is distributed to both common and subordinated units generally on a pro rata basis. The general partner is also eligible to receive incentive distributions if the general partner operates the business in a manner that results in distributions paid per common unit surpassing specified target levels. As the general partner increases cash distributions to the limited partners, the general partner receives an increasingly higher percentage of the incremental cash distributions. A common arrangement provides that the general partner can reach a tier where it receives 50% of every incremental dollar paid to common and subordinated unit holders. These incentive distributions encourage the general partner to streamline costs, increase capital expenditures and acquire assets in order to increase the partnership’s cash flow and raise the quarterly cash distribution in order to reach higher tiers. Such results benefit all security holders of the MLP.

MLP common units represent limited partnership interests in the MLP. Common units are listed and traded on US securities exchanges, with their values fluctuating predominantly based on prevailing market conditions and the success of the MLP. To the extent that a Fund invests in MLPs, it intends to purchase common units in market transactions. Unlike owners of common stock of a corporation, owners of common units have limited voting rights and have no ability annually to elect directors. In the event of liquidation, common units have preference over subordinated units, but not debt or preferred units, to the remaining assets of the MLP. A Fund intends to invest in MLPs only to an extent and in a manner consistent with the Fund’s qualification as a regulated investment company.

An investment in MLP units involves some risks that differ from an investment in the common stock of a corporation. Holders of MLP units have limited control and voting rights on matters affecting the partnership. Although common unitholders are generally limited in their liability, similar to a corporation’s shareholders, creditors typically have the right to seek the return of distributions made to such unitholders if the liability in question arose before the distribution was paid. This liability may stay attached to the common unitholder even after the units are sold. Investing in MLPs involves certain risks related to investing in the underlying assets of the MLPs and risks associated with pooled investment vehicles. MLPs holding credit-related investments are subject to interest rate risk and the risk of default on payment obligations by debt issuers. MLPs that concentrate in a particular industry or a particular geographic region are subject to risks associated with such industry or region. Investments held by MLPs may be relatively illiquid, limiting the MLPs’ ability to vary their portfolios promptly in response to changes in economic or other conditions. MLPs may have limited financial resources, their securities may trade infrequently and in limited volume, and they may be subject to more abrupt or erratic price movements than securities of larger or more broadly based companies.

Certain diversification and income requirements imposed by the Internal Revenue Code will limit the Funds’ ability to invest in MLP securities. In addition, a Fund’s ability to meet its investment objective may depend in part on the level of taxable income and distributions and dividends received from the MLP securities in which the Fund invests, a factor over which the Fund has no control. The benefit derived from a Fund’s investment in MLPs is largely dependent on the MLPs being treated as partnerships for federal income tax purposes. If an MLP were classified as a corporation for federal income tax purposes, the amount of cash available for distribution would be reduced and distributions received by a Fund would be taxed entirely as dividend income.

As a limited partner in the MLPs in which a Fund invests, the Fund will receive a pro rata share of income, gains, losses and deductions from those MLPs. Historically, a significant portion of income from such MLPs has been offset by tax deductions. A Fund’s shareholders will incur a current tax liability on that portion of an MLP’s income and gains that is not offset by tax deductions and losses. The percentage of an MLP’s income and gains that is offset by tax deductions and losses will fluctuate over time for various reasons.

Mortgage-Backed Securities (“MBS”)

A Fund may invest in MBS issued or guaranteed by the US government, its agencies or instrumentalities or government-sponsored corporations or those issued by certain private, non-government corporations, such as financial institutions.

Overview. MBS, also referred to as mortgage securities or mortgage-related securities, represent an ownership interest in a pool of mortgage loans, usually originated by mortgage bankers, commercial banks, savings and loan associations, savings banks, and credit unions to finance purchases of homes, commercial buildings, or other real estate. The individual mortgage loans are packaged or “pooled” together for sale to investors. These mortgage loans may have either fixed or adjustable interest rates. A guarantee or other form of credit support may be attached to an MBS to protect against default on obligations.

As the underlying mortgage loans are paid off, investors receive principal and interest payments, which “pass-through” when received from individual borrowers, net of any fees owed to the administrator, guarantor, or other service providers. Some MBS make payments of both principal and interest at a range of specified intervals; others make semiannual interest payments at a predetermined rate and repay principal at maturity (like a typical bond).

MBS are based on different types of mortgages, including those on commercial real estate or residential properties. The primary issuers or guarantors of MBS have historically been Ginnie Mae, Fannie Mae, and Freddie Mac. Other issuers of MBS include commercial banks and other private lenders.

Ginnie Mae is a wholly owned US government corporation within the Department of Housing and Urban Development. Ginnie Mae guarantees the principal and interest on securities issued by institutions approved by Ginnie Mae (such as savings and loan institutions, commercial banks and mortgage bankers). Ginnie Mae also guarantees the principal and interest on securities backed by pools of mortgages insured by the Federal Housing Administration (the “FHA”), or guaranteed by the Department of Veterans Affairs (the “VA”). Ginnie Mae’s guarantees are backed by the full faith and credit of the US government. Guarantees as to the timely payment of principal and interest do not extend to the value or yield of MBS nor do they extend to the value of a Fund’s shares which will fluctuate daily with market conditions.

Fannie Mae is a government-sponsored corporation, but its common stock is owned by private stockholders. Fannie Mae purchases conventional (i.e., not insured or guaranteed by any government agency) residential mortgages from a list of approved seller/servicers which include state and federally chartered savings and loan associations, mutual savings banks, commercial banks and credit unions, and mortgage bankers. Pass-through securities issued by Fannie Mae are guaranteed as to timely payment of principal and interest by Fannie Mae, but are not backed by the full faith and credit of the US government.

Freddie Mac was created by Congress in 1970 for the purpose of increasing the availability of mortgage credit for residential housing. It is a government-sponsored corporation formerly owned by the 12 Federal Home Loan Banks but now its common stock is owned entirely by private stockholders. Freddie Mac issues Participation Certificates (“PCs”), which are pass-through securities, each representing an undivided interest in a pool of residential mortgages. Freddie Mac guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the US government.

Although the MBS of Fannie Mae and Freddie Mac are not backed by the full faith and credit of the US government, the Secretary of the Treasury has the authority to support Fannie Mae and Freddie Mac by purchasing limited amounts of their respective obligations. The yields on these MBS have historically exceeded the yields on other types of US government securities with comparable maturities due largely to their prepayment risk. The US government, in the past, provided financial support to Fannie Mae and Freddie Mac, but no assurance can be given that the US government will continue to do so.

On September 6, 2008, the Federal Housing Finance Agency (“FHFA”) placed Fannie Mae and Freddie Mac into conservatorship. As the conservator, FHFA succeeded to all rights, titles, powers, and privileges of Fannie Mae and Freddie Mac and of any stockholder, officer, or director of Fannie Mae and Freddie Mac. FHFA selected a new chief executive officer and chairman of the board of directors for each of Fannie Mae and Freddie Mac. Also, the US Treasury entered into a Senior Preferred Stock Purchase Agreement imposing various covenants that severely limit each enterprise’s operations.

Fannie Mae and Freddie Mac continue to operate as going concerns while in conservatorship and each remains liable for all of its obligations, including its guaranty obligations associated with its MBS. The FHFA has the power to repudiate any contract entered into by Fannie Mae and Freddie Mac prior to FHFA’s appointment as conservator or receiver, including the guaranty obligations of Fannie Mae and Freddie Mac. Accordingly, securities issued by Fannie Mae and Freddie Mac will involve a risk of nonpayment of principal and interest.

MBS that are issued or guaranteed by the US government, its agencies or instrumentalities, are not subject to a Fund’s industry concentration restrictions, set forth under “Fundamental Investment Policies,” by virtue of the exclusion from that test available to securities issued or guaranteed by the US government or any of its agencies or instrumentalities. In the case of privately issued MBS, a Fund categorizes, where possible, the securities by the issuer’s industry for purposes of the Fund’s industry concentration restrictions.

Private MBS. Issuers of private MBS, such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers, and other secondary market issuers, are not US government agencies and may be both the originators of the underlying mortgage loans as well as the guarantors of the MBS, or they may partner with a government entity by issuing mortgage loans guaranteed or sponsored by the US government or a US government agency or sponsored enterprise. Pools of mortgage loans created by private issuers generally offer a higher rate of interest than government and government-related pools because there are no direct or indirect government or government agency guarantees of payment. The risk of loss due to default on private MBS is historically higher because neither the US government nor an agency or instrumentality has guaranteed them. Timely payment of interest and principal is, however, generally supported by various forms of insurance or guarantees, including individual loan, title, pool, and hazard insurance. Government entities, private insurance companies or the private mortgage poolers issue the insurance and guarantees. The insurance and guarantees and the creditworthiness of their issuers will be considered when determining whether an MBS meets a Fund’s quality standards. The Funds may buy MBS without insurance or guarantees if, through an examination of the loan experience and practices of the poolers, the Manager determines that the securities meet the Funds’ quality standards. Private MBS whose underlying assets are neither US government securities nor US government-insured mortgages, to the extent that real properties securing such assets may be located in the same geographical region, may also be subject to a greater risk of

default than other comparable securities in the event of adverse economic, political, or business developments that may affect such region and, ultimately, the ability of property owners to make payments of principal and interest on the underlying mortgages. Nongovernment MBS are generally subject to greater price volatility than those issued, guaranteed or sponsored by government entities because of the greater risk of default in adverse market conditions. Where a guarantee is provided by a private guarantor, a Fund is subject to the credit risk of such guarantor, especially when the guarantor doubles as the originator.

CMOs and REMICs. Some MBS known as collateralized mortgage obligations (“CMOs”) are divided into multiple classes. Each of the classes is allocated a different share of the principal and/or interest payments received from the pool according to a different payment schedule depending on, among other factors, the seniority of a class relative to their classes. Other MBS such as real estate mortgage investment conduits (REMICs) are also divided into multiple classes with different rights to the interest and/or principal payments received on the pool of mortgages. A CMO or REMIC may designate the most junior of the securities it issues as a “residual” which will be entitled to any amounts remaining after all classes of shareholders (and any fees or expenses) have been paid in full. Some of the different rights may include different maturities, interest rates, payment schedules, and allocations of interest and/or principal payments on the underlying mortgage loans. Multi-class pass-through securities are equity interests in a trust composed of mortgage loans or other MBS. Payments of principal and interest on the underlying collateral provide the resources to pay the debt service on CMOs or REMICs or to make scheduled distributions on the multi-class pass-through securities. Unless the context indicates otherwise, the discussion of CMOs below also applies to REMICs and multi-class pass-through securities.

All the risks applicable to a traditional MBS also apply to the CMO or REMIC taken as a whole, even though certain classes of the CMO or REMIC will be protected against a particular risk by subordinated classes. The risks associated with an investment in a particular CMO or REMIC class vary substantially depending on the combination of rights associated with that class. An investment in the most subordinated classes of a CMO or REMIC bears a disproportionate share of the risks associated with MBS generally, be it credit risk, prepayment or extension risk (the risk of a security’s expected maturity being reduced or lengthened in duration due to a change of the timing of payment), interest rate risk, income risk, market risk, liquidity risk or any other risk associated with a debt or equity instrument with similar features to the relevant class. As a result, an investment in the most subordinated classes of a CMO or REMIC is often riskier than an investment in other types of MBS.

CMOs are generally required to maintain more collateral than REMICs to collateralize the CMOs being issued. Most REMICs are not subject to the same minimum collateralization requirements and may be permitted to issue the full value of their assets as securities, without reserving any amount as collateral. As a result, an investment in the subordinated classes of a REMIC may be riskier than an investment in equivalent classes of a CMO.

CMOs may be issued, guaranteed or sponsored by governmental entities or by private entities. Consequently, they involve risks similar to those of traditional MBS that have been issued, guaranteed, or sponsored by such government and/or private entities. For example, a Fund is generally exposed to a greater risk of loss due to default when investing in CMOs that have not been issued, guaranteed, or sponsored by a government entity.

CMOs are typically issued in multiple classes. Each class, often referred to as a “tranche,” is issued at a specified coupon rate or adjustable rate and has a stated maturity or final distribution date. Principal prepayments on collateral underlying CMOs may cause the CMOs to be retired substantially earlier than their stated maturities or final distribution dates. Interest is paid or accrues on most classes of a CMO on a monthly, quarterly or semiannual basis. The principal and interest on the mortgages underlying CMOs may be allocated among the several classes in many ways. In a common structure, payments of principal on the underlying mortgages, including any principal prepayments, are applied to the classes of a series of a CMO in the order of their respective stated maturities or final distribution dates, so that no payment of principal will be made on any class until all other classes having an earlier stated maturity or final distribution date have been paid in full.

The Funds may invest in parallel-pay and planned amortization class (“PAC”) CMOs and multi-class pass through certificates. Parallel-pay CMOs and multi-class passthrough certificates are structured to provide payments of principal on each payment date to more than one class. These simultaneous payments are taken into account in calculating the stated maturity date or final distribution date of each class, which, as with other CMO and multi-class pass-through structures, must be retired by its stated maturity date or final distribution date but may be retired earlier. PACs generally require payments of a specified amount of principal on each payment date. PACs are parallel-pay CMOs with the required principal amount on such securities having the highest priority after interest has been paid to all classes. Any CMO or multi-class pass through structure that includes PAC securities must also have support tranches — known as support bonds, companion bonds or non-PAC bonds — which lend or absorb principal cash flows to allow the PAC securities to maintain their stated maturities and final distribution dates within a range of actual prepayment experience. These support tranches are subject to a higher level of maturity risk compared to other mortgage-related securities, and usually provide a higher yield to compensate investors. If principal cash flows are received in amounts outside a pre-determined range such that the support bonds cannot lend or absorb sufficient cash flows to the PAC securities as intended, the PAC securities are subject to heightened maturity risk.

One or more classes of a CMO may have interest rates that reset periodically as adjustable-rate mortgage loans (“ARMs”) do. These adjustable rate classes are known as “floating-rate CMOs” and are subject to most risks associated with ARMs. Floating-rate CMOs may be backed by fixed- or adjustable-rate mortgages. To date, fixed-rate mortgages have been more commonly used for this purpose. Floating-rate CMOs are typically issued with lifetime “caps” on the interest rate. These caps, similar to the caps on ARMs, limit a Fund’s potential to gain from rising interest rates and increase the sensitivity of the CMO’s price to interest rate changes while rates remain above the cap.

Timely payment of interest and principal (but not the market value and yield) of some of these pools is supported by various forms of insurance or guarantees issued by private issuers, those who pool the mortgage assets and, in some cases, by US government agencies.

CMOs involve risks including the uncertainty of the timing of cash flows that results from the rate of prepayments on the underlying mortgages serving as collateral, and risks resulting from the structure of the particular CMO transaction and the priority of the individual tranches. The prices of some CMOs, depending on their structure and the rate of prepayments, can be volatile. Some CMOs may be less liquid than other types of MBS. As a result, it may be difficult or impossible to sell the securities at an advantageous price or time under certain circumstances. Yields on privately issued CMOs have been historically higher than the yields on CMOs issued and guaranteed by US government agencies or instrumentalities. The risk of loss due to default on privately issued CMOs, however, is historically higher since the US government has not guaranteed them.

To the extent any privately issued CMOs in which a Fund invests are considered by the SEC to be an investment company, the Fund will limit its investments in such securities in a manner consistent with the provisions of the 1940 Act.

Commercial mortgage-backed securities (“CMBS”). CMBS are issued by special purpose entities that represent an undivided interest in a portfolio of mortgage loans backed by commercial properties. The loans are collateralized by various types of commercial property, which include, but are not limited to, multifamily housing, retail shopping centers, office space, hotels, and healthcare facilities. Private lenders, such as banks or insurance companies, originate these loans and then sell the loans directly into a CMBS trust or other entity. CMBS are subject to credit risk, prepayment risk, and extension risk. The Manager, through its careful credit analysis, attempts to address the risk of an issuer being unable to make timely payments of interest and principal. Although prepayment risk is present, it is of a lesser degree in CMBS than in the residential mortgage market.

Stripped mortgage securities. Some MBS referred to as stripped MBS are divided into classes which receive different proportions of the principal and interest payments or, in some cases, only payments of principal or interest (but not both). Other MBS referred to as net interest margin (“NIM”) securities give the investor the right to receive any excess interest earned on a pool of mortgage loans remaining after all classes and service providers have been paid in full. Stripped MBS may be issued by government or private entities. Stripped MBS issued or guaranteed by agencies or instrumentalities of the US government are typically more liquid than privately issued stripped MBS.

Stripped MBS are usually structured with two classes, each receiving different proportions of the interest and principal distributions on a pool of mortgage assets. In most cases, one class receives all of the interest (the interest-only or “IO” class), while the other class receives all of the principal (the principal-only or “PO” class). The return on an IO class is extremely sensitive not only to changes in prevailing interest rates but also to the rate of principal payments (including prepayments) on the underlying mortgage assets. A rapid rate of principal payments may have a material adverse effect on any IO class held by the Funds. If the underlying mortgage assets experience greater than anticipated prepayments of principal, a Fund may fail to recoup its initial investment fully, even if the securities are rated in the highest rating categories, AAA or Aaa, by S&P or Moody’s, respectively.

NIM securities represent a right to receive any “excess” interest computed after paying coupon costs, servicing costs and fees and any credit losses associated with the underlying pool of home equity loans. Like traditional stripped MBS, the return on a NIM security is sensitive not only to changes in prevailing interest rates but also to the rate of principal payments (including prepayments) on the underlying home equity loans. NIM securities are highly sensitive to credit losses on the underlying collateral and the timing in which those losses are taken.

Stripped MBS and NIM securities tend to exhibit greater market volatility in response to changes in interest rates than other types of MBS and are purchased and sold by institutional investors, such as a Fund, through investment banking firms acting as brokers or dealers. Some of these securities may be deemed “illiquid” and therefore subject to a Fund’s limitation on investment in illiquid investments and the risks associated with illiquidity.

Mortgage loan and home equity loan pools offering pass-through investments in addition to those described above may be created in the future. The mortgages underlying these securities may be alternative mortgage instruments, that is, mortgage instruments whose principal or interest payments may vary or whose terms to maturity may differ from customary long-term, fixed-rate mortgages. As new types of mortgage and home equity loan securities are developed and offered to investors, a Fund may invest in them if they are consistent with the Fund’s goals, policies and quality standards.

Additional risks. In addition to the special risks described below, MBS are subject to many of the same risks as other types of debt securities. The market value of MBS, like other debt securities, will generally vary inversely with changes in market interest rates, declining when interest rates rise and rising when interest rates decline. MBS differ from conventional debt securities in that most MBS are pass-through securities. This means that they typically provide investors with periodic payments (typically monthly) consisting of a pro rata share of both regular interest and principal payments, as well as unscheduled early prepayments, on the underlying mortgage pool (net of any fees paid to the issuer or guarantor of such securities and any applicable loan servicing fees). As a result, the holder of the MBS (i.e., a Fund) receives scheduled payments of principal and interest and may receive unscheduled principal payments representing prepayments on the underlying mortgages. The rate of prepayments on the underlying mortgages generally increases as interest rates decline, and when a Fund reinvests the payments and any unscheduled prepayments of principal it receives, it may receive a rate of interest that is lower than the rate on the existing MBS. For this reason, pass-through MBS may have less potential for capital appreciation as interest rates decline and may be less effective than other types of US government or other debt securities as a means of “locking in” long-term interest rates. In general, fixed rate MBS have greater exposure to this “prepayment risk” than variable rate securities.

An unexpected rise in interest rates could extend the average life of an MBS because of a lower than expected level of prepayments or higher than expected amounts of late payments or defaults. In addition, to the extent MBS are purchased at a premium, mortgage foreclosures and unscheduled principal prepayments may result in some loss of the holder’s principal investment to the extent of the premium paid. On the other hand, if MBS are purchased at a discount, both a scheduled payment of principal and an unscheduled prepayment of principal will increase current and total returns and will accelerate the recognition of income that, when distributed to shareholders, will generally be treated as ordinary income. Regulatory or tax changes may also adversely affect the MBS market as a whole.

Guarantees. The existence of a guarantee or other form of credit support on an MBS usually increases the price that a Fund pays for the security. There is always the risk that the guarantor will default on its obligations. When the guarantor is the US government, there is minimal risk of guarantor default. However, the risk remains if the credit support or guarantee is provided by a private party or a US government agency or sponsored enterprise. Even if the guarantor meets its obligations, there can be no assurance that the type of guarantee or credit support provided will be effective at reducing losses or delays to investors, given the nature of the default. A guarantee only assures timely payment of interest and principal, not a particular rate of return on a Fund’s investment or protection against prepayment or other risks. The market price and yield of the MBS at any given time are not guaranteed and are likely to fluctuate.

Municipal Bonds

Municipal bonds are generally understood to include debt obligations issued to obtain funds for various public purposes, including the construction of a wide range of public facilities such as airports, bridges, highways, housing, hospitals, mass transportation, schools, streets, and water and sewer works. Other public purposes for which municipal bonds may be issued include the refunding of outstanding obligations, obtaining funds for general capital expenses, and the obtaining of funds to lend to other public institutions and facilities. In addition, certain types of industrial development bonds are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, sports facilities, convention or trade show facilities, airport, mass transit, port or parking facilities, air or water pollution control facilities, and certain local facilities for water supply, gas, electricity, or sewage or solid waste disposals. Such obligations are included within the term “municipal bonds” provided that the interest paid thereon qualifies as exempt from federal income tax in the opinion of bond counsel to the issuer. In addition, the interest paid on industrial development bonds, the proceeds from which are used for the construction, equipment, repair, or improvement of privately operated industrial or commercial facilities, may be exempt from federal income tax, although current federal tax laws place substantial limitations on the size of such issues.

The two principal classifications of municipal bonds are “general obligation” and “revenue” bonds. General obligation bonds are secured by the issuer’s pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source, but not from the general taxing power. Tax exempt industrial development bonds are, in most cases, revenue bonds and do not generally carry the pledge of the credit of the issuer of such bonds. There are, of course, variations in the security of municipal bonds, both within a particular classification and between classifications.

The yields on municipal bonds are dependent on a variety of factors, including general money market conditions, general conditions of the municipal bond market, size of a particular offering, maturity of the obligations, and rating of the issue. The imposition of a Fund’s management fee, as well as other operating expenses, will have the effect of reducing the yield to investors.

Tender option bonds. A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security’s fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. A Fund’s investment adviser will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

Options

Options, a type of potentially high-risk derivative, give the investor the right (where the investor purchases the option), or the obligation (where the investor “writes” or sells the option), to buy or sell an asset at a predetermined price in the future. Options contracts may be bought or sold for any number of reasons, including: to manage a Fund’s exposure to changes in securities prices and foreign currencies; as an efficient means of adjusting a Fund’s overall exposure to certain markets; in an effort to enhance income; to protect the value of portfolio securities; and as a cash management tool. Call or put options may be purchased or sold on securities, financial indices, and foreign currencies. Options may not always be successful hedges; their prices can be highly volatile; and using them could lower a Fund’s total return. Optimum Fixed Income Fund may purchase and write call and put options and may engage in option strategies for hedging and/or non-hedging purposes.

A Fund may write covered call options from time to time on such portion of its portfolio, without limit, as the investment adviser determines is appropriate in seeking to obtain the Fund’s investment objective. Optimum Large Cap Growth Fund, Optimum Small-Mid Cap Value Fund, Optimum Large Cap Value Fund, Optimum International Fund, and Optimum Small-Mid Cap Growth Fund will write call options only on a covered basis, which means that each Fund will own the underlying security subject to a call option at all times during the option period. Unless a closing purchase transaction is effected, the Fund would be required to continue to hold a security that it might otherwise wish to sell or deliver a security it would want to hold. A Fund also may purchase call options. The advantage of purchasing call options is that the Fund may alter portfolio characteristics and modify portfolio maturities without incurring the cost associated with portfolio transactions.

A Fund may purchase put options. A Fund will, at all times during which it holds a put option, own the security covered by such option. A put option purchased by a Fund gives it the right to sell one of its securities for an agreed upon price up to an agreed upon date. A Fund may purchase put options in order to protect against a decline in market value of the underlying security below the exercise price less the premium paid for the option (“protective puts”). A Fund may sell a put option purchased on individual portfolio securities.

A Fund may write call options and purchase put options on certain stock indices and enter into closing transactions in connection therewith. A Fund also may sell a put option purchased on stock indices. A Fund also may purchase call options on stock indices and enter into closing transactions in connection therewith. Optimum Large Cap Growth Fund, Optimum Small-Mid Cap Value Fund, Optimum Large Cap Value Fund, Optimum International Fund, and Optimum Small-Mid Cap Growth Fund will not engage in transactions in options on stock indices for speculative purposes but only to protect appreciation attained, to offset capital losses and to take advantage of the liquidity available in the option markets. A Fund also may purchase or sell (write) put options on securities as a means of achieving additional return or of hedging the value of the Fund’s portfolio. Optimum Large Cap Growth Fund, Optimum Small-Mid Cap Value Fund, Optimum Large Cap Value Fund, Optimum International Fund, and Optimum Small-Mid Cap Growth Fund will write only “covered” options.

To the extent authorized to engage in option transactions, a Fund may invest in options that are exchange listed or traded over-the-counter. Certain over-the-counter options may be illiquid. A Fund will enter into an option position only if there appears to be a liquid market for such options. However, there can be no assurance that a liquid secondary market will be maintained. Thus, it may not be possible to close option positions, which may have an adverse impact on a Fund’s ability to effectively hedge its securities. A Fund will enter into such options only to the extent consistent with its limitations on investments in illiquid investments.

Overview. An option is a contract that gives the purchaser of the option, in return for the premium paid, the right to buy an underlying reference instrument, such as a specified security, currency, index, or other instrument, from the writer of the option (in the case of a call option), or to sell a specified reference instrument to the writer of the option (in the case of a put option) at a designated price during the term of the option. The premium paid by the buyer of an option will reflect, among other things, the relationship of the exercise price to the market price and the volatility of the underlying reference instrument; the remaining term of the option, supply, demand, or interest rates; and/or currency exchange rates. An American style put or call option may be exercised at any time during the option period while a European style put or call option may be exercised only upon expiration or during a fixed period prior thereto. Put and call options are traded on national securities exchanges and in the OTC market.

Options traded on national securities exchanges are within the jurisdiction of the SEC or other appropriate national securities regulator, as are securities traded on such exchanges. As a result, many of the protections provided to traders on organized exchanges will be available with respect to such transactions. In particular, all option positions entered into on a national securities exchange in the US are cleared and guaranteed by the Options Clearing Corporation, thereby reducing the risk of counterparty default. Furthermore, a liquid secondary market in options traded on a national securities exchange may be more readily available than in the OTC market, potentially permitting a Fund to liquidate open positions at a profit prior to exercise or expiration, or to limit losses in the event of adverse market movements. There is no assurance, however, that higher than anticipated trading activity or other unforeseen events might not temporarily render the capabilities of the Options Clearing Corporation inadequate, and thereby result in the exchange instituting special procedures which may interfere with the timely execution of a Fund’s orders to close out open options positions.

Purchasing call and put options. As the buyer of a call option, a Fund has a right to buy the underlying reference instrument (e.g., a currency or security) at the exercise price at any time during the option period (for American style options). A Fund may enter into closing sale transactions with respect to call options, exercise them, or permit them to expire. For example, a Fund may buy call options on underlying reference instruments that it intends to buy with the goal of limiting the risk of a substantial increase in their market price before the purchase is effected. Unless the price of the underlying reference instrument changes sufficiently, a call option purchased by a Fund may expire without any value to the Fund, in which case the Fund would experience a loss to the extent of the premium paid for the option plus related transaction costs.

As the buyer of a put option, a Fund has the right to sell the underlying reference instrument at the exercise price at any time during the option period (for American style options). As with a call option, a Fund may enter into closing sale transactions with respect to put options, exercise them or permit them to expire. A Fund may buy a put option on an underlying reference instrument owned by the Fund (a protective put) as a hedging technique in an attempt to protect against an anticipated decline in the market value of the underlying reference instrument. Such hedge protection is provided only during the life of the put option when a Fund, as the buyer of the put option, is able to sell the underlying reference instrument at the put exercise price, regardless of any decline in the underlying instrument’s market price. A Fund may also seek to offset a decline in the value of the underlying reference instrument through appreciation in the value of the put option. A put option may also be purchased with the intent of protecting unrealized appreciation of an instrument when the Manager deems it desirable to continue to hold the instrument because of tax or other considerations. The premium paid for the put option and any transaction costs would reduce any short-term capital gain that may be available for distribution when the instrument is eventually sold. Buying put options at a time when the buyer does not own the underlying reference instrument allows the buyer to benefit from a decline in the market price of the underlying reference instrument, which generally increases the value of the put option.

If a put option were not terminated in a closing sale transaction when it has remaining value, and if the market price of the underlying reference instrument remains equal to or greater than the exercise price during the life of the put option, the buyer would not make any gain upon exercise of the option and would experience a loss to the extent of the premium paid for the option plus related transaction costs. In order for the purchase of a put option to be profitable, the market price of the underlying reference instrument must decline sufficiently below the exercise price to cover the premium and transaction costs.

Writing call and put options. Writing options may permit the writer to generate additional income in the form of the premium received for writing the option. The writer of an option may have no control over when the underlying reference instruments must be sold (in the case of a call option) or purchased (in the case of a put option) because the writer may be notified of exercise at any time prior to the expiration of the option (for American style options). Whether or not an option expires unexercised, the writer retains the amount of the premium. Writing “covered” call options means that the writer owns the underlying reference instrument that is subject to the call option. Optimum Large Cap Growth Fund, Optimum Small-Mid Cap Value Fund, Optimum Large Cap Value Fund, Optimum International Fund, and Optimum Small-Mid Cap Growth Fund will write call options on a covered basis only.

As the writer of a covered call option, a Fund gives up the potential for capital appreciation above the exercise price of the option should the underlying reference instrument rise in value. If the value of the underlying reference instrument rises above the exercise price of the call option, the reference instrument will likely be “called away,” requiring a Fund to sell the underlying instrument at the exercise price. In that case, a Fund will sell the underlying reference instrument to the option buyer for less than its market value, and the Fund will experience a loss (which will be offset by the premium received by the Fund as the writer of such option). If a call option expires unexercised, a Fund will realize a gain in the amount of the premium received. If the market price of the underlying reference instrument decreases, the call option will not be exercised and a Fund will be able to use the amount of the premium received to hedge against the loss in value of the underlying reference instrument. The exercise price of a call option will be chosen based upon the expected price movement of the underlying reference instrument. The exercise price of a call option may be below, equal to (at-the-money), or above the current value of the underlying reference instrument at the time the option is written.

As the writer of a put option, a Fund has a risk of loss should the underlying reference instrument decline in value. If the value of the underlying reference instrument declines below the exercise price of the put option and the put option is exercised, the Fund, as the writer of the put option, will be required to buy the instrument at the exercise price, which will exceed the market value of the underlying reference instrument at that time. A Fund will incur a loss to the extent that the current market value of the underlying reference instrument is less than the exercise price of the put option. However, the loss will be offset in part by the premium received from the buyer of the put. If a put option written by a Fund expires unexercised, the Fund will realize a gain in the amount of the premium received.

Closing out options (exchange-traded options). As the writer of an option, if a Fund wants to terminate its obligation, the Fund may effect a “closing purchase transaction” by buying an option of the same series as the option previously written. The effect of the purchase is that the clearing corporation will cancel a Fund’s position. However, a writer may not effect a closing purchase transaction after being notified of the exercise of an option. Likewise, the buyer of an option may recover all or a portion of the premium that it paid by effecting a “closing sale transaction” by selling an option of the same series as the option previously purchased and receiving a premium on the sale. There is no guarantee that either a closing purchase or a closing sale transaction may be made at a time desired by a Fund. Closing transactions allow a Fund to terminate its positions in written and purchased options. A Fund will realize a profit from a closing transaction if the price of the transaction is less than the premium received from writing the original option (in the case of written options) or is more than the premium paid by the Fund to buy the option (in the case of purchased options). For example, increases in the market price of a call option sold by a Fund will generally reflect increases in the market price of the underlying reference instrument. As a result, any loss resulting from a closing transaction on a written call option is likely to be offset in whole or in part by appreciation of the underlying instrument owned by a Fund.

Over-the-counter (“OTC”) options. Like exchange-traded options, OTC options give the holder the right to buy from the writer, in the case of OTC call options, or sell to the writer, in the case of OTC put options, an underlying reference instrument at a stated exercise price. OTC options, however, differ from exchange-traded options in certain material respects.

OTC options are arranged directly with dealers and not with a clearing corporation or exchange. Consequently, there is a risk of nonperformance by the dealer, including because of the dealer’s bankruptcy or insolvency. While a Fund uses only counterparties, such as dealers, that meet its credit quality standards, in unusual or extreme market conditions, a counterparty’s creditworthiness and ability to perform may deteriorate rapidly, and the availability of suitable replacement counterparties may become limited. Because there is no exchange, pricing is typically done based on information from market makers or other dealers. OTC options are available for a greater variety of underlying reference instruments and in a wider range of expiration dates and exercise prices than exchange-traded options.

There can be no assurance that a continuous liquid secondary market will exist for any particular OTC option at any specific time. A Fund may be able to realize the value of an OTC option it has purchased only by exercising it or entering into a closing sale transaction with the dealer that issued it. When a Fund writes an OTC option, it generally can close out that option prior to its expiration only by entering into a closing purchase transaction with the dealer with which the Fund originally wrote the option. A Fund may suffer a loss if it is not able to exercise the option (in the case of a purchased option) or enter into a closing sale transaction on a timely basis.

Risks of options. A Fund’s options investments involve certain risks, including general risks related to derivatives instruments. There can be no assurance that a liquid secondary market on an exchange will exist for any particular option, or at any particular time, and a Fund may have difficulty effecting closing transactions in particular options. Therefore, a Fund would have to exercise the options it purchased in order to realize any profit, thus taking or making delivery of the underlying reference instrument when not desired. A Fund could then incur transaction costs upon the sale of the underlying reference instruments. Similarly, when a Fund cannot effect a closing transaction with respect to a put option it wrote, and the buyer exercises, the Fund would be required to take delivery and would incur transaction costs upon the sale of the underlying reference instruments purchased. If a Fund, as a covered call option writer, is unable to effect a closing purchase transaction in a secondary market, it will not be able to sell the underlying reference instrument until the option expires, it delivers the underlying instrument upon exercise, or it segregates enough liquid assets to purchase the underlying reference instrument at

the marked-to-market price during the term of the option. When trading options on non-US exchanges or in the OTC market, many of the protections afforded to exchange participants will not be available. For example, there may be no daily price fluctuation limits, and adverse market movements could therefore continue to an unlimited extent over an indefinite period of time.

The effectiveness of an options strategy for hedging depends on the degree to which price movements in the underlying reference instruments correlate with price movements in the relevant portion of a Fund’s portfolio that is being hedged. In addition, a Fund bears the risk that the prices of its portfolio investments will not move in the same amount as the option it has purchased or sold for hedging purposes, or that there may be a negative correlation that would result in a loss on both the investments and the option. If the Manager is not successful in using options in managing a Fund’s investments, the Fund’s performance will be worse than if the Manager did not employ such strategies.

Preferred Securities

Preferred securities represent an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other stocks such as common stocks, dividends and a fixed share of the proceeds resulting from a liquidation of the company. Some preferred stocks also entitle their holders to receive additional liquidation proceeds on the same basis as holders of a company’s common stock, and thus also represent an ownership interest in that company.

Preferred stocks may pay fixed or adjustable rates of return. Preferred stock is subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company’s preferred stock generally pays dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred stock will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred stock of smaller companies may be more vulnerable to adverse developments than preferred stock of larger companies.

Real Estate Investment Trusts (“REITs”)

REITs are pooled investment vehicles that invest primarily in income-producing real estate or in mortgages and loans collateralized by real estate. “Equity” REITs are real estate companies that own and manage income-producing properties such as apartments, hotels, shopping centers, or office buildings. The income, primarily rent from these properties, is generally passed on to investors in the form of dividends. These companies provide experienced property management and generally concentrate on a specific geographic region or property type. “Mortgage” REITs make loans to commercial real estate developers and earn income from interest payments. A hybrid REIT combines the characteristics of Equity REITs and Mortgage REITs, generally by holding both ownership interest and mortgage interests in real estate. Although not required, the Manager anticipates that under normal circumstances the Funds will invest primarily in Equity REITs. Although the REIT structure originated in the US, a number of countries around the world have adopted, or are considering adopting, similar REIT and REIT-like structures.

For US federal tax law purposes, to qualify as a REIT, a company must derive at least 75% of its gross income from real estate sources (rents, mortgage interest, or gains from the sale of real estate assets), and at least 95% from real estate sources, plus dividends, interest, and gains from the sale of securities. Real property, mortgage loans, cash, and certain securities must comprise 75% of a company’s assets. In order to qualify as a REIT, a company must also make distributions to shareholders aggregating annually at least 90% of its REIT taxable income.

REIT risks. A Fund’s investments in REITs present certain further risks that are unique and in addition to the risks associated with investing in the real estate industry in general. Equity REITs may be affected by any changes in the value of the underlying properties owned by the REITs and other factors and their prices tend to go up and down, while mortgage REITs may be affected by the quality of any credit extended. REITs are not diversified and are subject to the risks of financing projects. A REIT’s performance depends on the types and locations of the properties it owns and on management skills. A decline in rental income may occur because of extended vacancies, increased competition from other properties, tenants’ failure to pay rent, or poor management. REITs whose underlying assets include US long-term healthcare properties, such as nursing, retirement and assisted living homes, may be impacted by US federal regulations concerning the healthcare industry. A REIT’s performance also depends on the company’s ability to finance property purchases and renovations and manage its cash flows.

REITs (especially mortgage REITs) are also subject to interest rate risks — when interest rates decline, the value of a REIT’s investment in fixed-rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a REIT’s investment in fixed-rate obligations can be expected to decline. In contrast, as interest rates on adjustable-rate mortgage loans are reset periodically, yields on a REIT’s investments in such loans will gradually align themselves to reflect changes in market interest rates, causing the value of such investments to fluctuate less dramatically in response to interest rate fluctuations than would investments in fixed-rate obligations.

Because REITs typically are invested in a limited number of projects or in a particular market segment, REITs may have limited financial resources, may trade less frequently and in a limited volume, and may be subject to more abrupt or erratic price movements than other securities. Loss of status as a qualified REIT under the US federal tax laws could adversely affect the value of a particular REIT or the market for REITs as a whole.

Repurchase Agreements

Each Fund may, from time to time, enter into repurchase agreement transactions which are at least 102% collateralized by US government securities.

Under a repurchase agreement, a Fund agrees to buy securities guaranteed as to payment of principal and interest by the US government or its agencies or instrumentalities from a qualified bank or broker/dealer and then to sell the securities back to the bank or broker/dealer on an agreed upon date (generally less than seven days) at a higher price, which reflects currently prevailing short-term interest rates. Entering into repurchase agreements allows a Fund to earn a return on cash in the Fund’s portfolio that would otherwise remain uninvested. The bank or broker/dealer must transfer to a Fund’s custodian, as collateral, securities with an initial market value of at least 102% of the dollar amount paid by the Fund to the counterparty. The Manager will monitor the value of such collateral daily to determine that the value of the collateral equals or exceeds the repurchase price.

Repurchase agreements may involve risks in the event of default or insolvency of the bank or broker/dealer, including possible delays or restrictions upon a Fund’s ability to sell the underlying securities and additional expenses in seeking to enforce the Fund’s rights and recover any losses. A Fund will enter into repurchase agreements only with parties who meet certain creditworthiness standards, i.e., banks or broker/dealers that the Manager has determined, based on the information available at the time, present no serious risk of becoming involved in bankruptcy proceedings within the time frame contemplated by the repurchase agreement. Although a Fund seeks to limit the credit risk under a repurchase agreement by carefully selecting counterparties and accepting only high-quality collateral, some credit risk remains. The counterparty could default, which may make it necessary for a Fund to incur expenses to liquidate the collateral. In addition, the collateral may decline in value before it can be liquidated by a Fund. A repurchase agreement with more than seven days to maturity may be considered an illiquid investment and may be subject to a Fund’s investment restriction on illiquid investments.

Delaware Funds by Macquarie​® (each a “Delaware Fund” and collectively, “Delaware Funds”) and the Funds have obtained an exemption (the “Order”) from the joint-transaction prohibitions of Section 17(d) of the 1940 Act to allow Delaware Funds and the Funds jointly to invest cash balances. A Fund may invest cash balances in a joint repurchase agreement in accordance with the terms of the Order and subject generally to the conditions described above.

Reverse Repurchase Agreements

The Funds are authorized to enter into reverse repurchase agreements.

A reverse repurchase agreement is the sale of a security by a Fund and its agreement to repurchase the security at a specified time and price. This practice of segregating assets is referred to as “cover.” Reverse repurchase agreements covered in this manner are not treated as secure securities for purposes of a Fund’s fundamental investment limitation on senior securities and borrowings. To the extent that a Fund enters into reverse repurchase agreements with banks, the Fund may cover its obligations in the manner described above, or treat such transactions as borrowings and will limit its investments in such uncovered agreements, together with any other borrowings, to no more than one-third of its total assets. The use of reverse repurchase agreements by a Fund creates leverage which increases the Fund’s investment risk. If the income and gains on securities purchased with the proceeds of reverse repurchase agreements exceed the costs of the agreements, a Fund’s earnings or NAV will increase faster than otherwise would be the case; conversely, if the income and gains fail to exceed the costs, earnings or NAV would decline faster than otherwise would be the case.

“Roll” Transactions

The Funds may engage in “roll” transactions.

A “roll” transaction is the sale of securities together with a commitment, for which a Fund may receive a fee, to purchase similar, but not identical, securities at a future date. Although these transactions will not be entered into for leveraging purposes, to the extent a Fund’s aggregate commitments under these transactions exceed its holdings of cash and securities that do not fluctuate in value (such as short-term money market instruments), the Fund temporarily will be in a leveraged position (i.e., it will have an amount greater than its net assets subject to market risk). Should the market value of a Fund’s portfolio securities decline while it is in a leveraged position, greater depreciation of its net assets would likely occur than were it not in such a position. As a Fund’s aggregate commitments under these transactions increase, its leverage risk similarly increases.

Securities Lending

Each Fund may loan up to 25% of its assets to qualified broker/dealers or institutional investors for their use relating to short sales or other security transactions.

A Fund, along with funds in the Delaware Funds, may lend its securities pursuant to a security lending agreement (“Lending Agreement”) with The Bank of New York Mellon (“BNY Mellon”). At the time a security is loaned, the borrower must post collateral equal to the required percentage of the market value of the loaned security, including any accrued interest. The required percentage is: (i) 102% with respect to US securities and foreign securities that are denominated and payable in US dollars; and (ii) 105% with respect to foreign securities. With respect to each loan if, on any business day, the aggregate market value of securities collateral plus cash collateral held is less than the aggregate market value of the securities which are the subject of such loan, the borrower will be notified to provide additional collateral by the end of the following business day which, together with the collateral already held, will be not less than the applicable initial collateral requirements for such security loan. If the aggregate market value of securities collateral and cash collateral held with respect to a security loan exceeds the applicable initial collateral requirement, upon the request of the borrower, BNY Mellon must return enough collateral to the borrower by the end of the following business day to reduce the value of the remaining collateral to the applicable initial collateral requirement for such security loan. As a result of the foregoing, the value of the collateral held with respect to a loaned security on any particular day may be more or less than the value of the security on loan.

The investment guidelines permit each separate account to hold certain securities that would be considered eligible securities for a money market fund. Cash collateral received is generally invested in government securities; certain obligations issued by government sponsored enterprises; repurchase agreements collateralized by US Treasury securities; certain obligations issued by the central government of any Organization for Economic Cooperation and Development (OECD) country or its agencies, instrumentalities or establishments; certain obligations of supranational organizations, commercial paper, notes, bonds and other debt obligations; certificates of deposit, time deposits and other bank obligations; and asset-backed securities.

A Fund can also accept US government securities and letters of credit (non-cash collateral) in connection with securities loans. In the event of default or bankruptcy by the lending agent, realization and/or retention of the collateral may be subject to legal proceedings. In the event the borrower fails to return loaned securities and the collateral received is insufficient to cover the value of the loaned securities and provided such collateral shortfall is not the result of investment losses, the lending agent has agreed to pay the amount of the shortfall to a Fund or, at the discretion of the lending agent, replace the loaned securities. A Fund continues to record dividends or interest, as applicable, on the securities loaned and is subject to changes in value of the securities loaned that may occur during the term of the loan. A Fund has the right under the Lending Agreement to recover the securities from the borrower on demand. With respect to security loans collateralized by non-cash collateral, a Fund receives loan premiums paid by the borrower. With respect to security loans collateralized by cash collateral, the earnings from the collateral investments are shared among a Fund, the security lending agent, and the borrower. A Fund records security lending income net of allocations to the security lending agent and the borrower.

Short Sales Against the Box

A Fund may enter into a short sale against the box to hedge against anticipated declines in the market price of portfolio securities or for certain other limited purposes. If the value of the securities sold short increases prior to the scheduled delivery date, a Fund loses the opportunity to participate in the gain.

Short Sales of Exchange-Traded Funds

Optimum Fixed Income Fund may make short sales on exchange-traded funds in an attempt to isolate, manage, or reduce the risk of individual securities positions held by the Fund, of a decline in a particular market sector to which the Fund has significant exposure, or of the exposure to securities owned by the Fund in the aggregate. Such short sales may also be implemented in an attempt to manage the duration of the Fund’s holdings. Short sales of exchange-traded funds will not be utilized for speculative purposes. The Fund’s total investments in exchange-traded funds will not exceed 5% of net assets in any one exchange-traded fund and 10% in all positions in investment companies, including exchange-traded funds, in the aggregate.

Typically, short sales are transactions in which the Fund sells a security that the Fund has borrowed, but that it does not own and, at the time a short sale is effected, the Fund incurs an obligation to replace the security borrowed. The price at the time of replacement may be more or less than the price at which the security was sold by the Fund. When a short sale transaction is closed out by delivery of the security, any gain or loss on the transaction generally is taxable as short-term capital gain or loss. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases between the date of the short sale and the date on which the Fund replaces the borrowed security; conversely, the Fund will realize a gain if the security declines in price between those dates. This result is the opposite of what one would expect from a cash purchase of a long position in a security.

Moreover, although the trading price of a share of an exchange-traded fund normally tracks the net asset value of such a share, in times of market stress, this value relationship will not necessarily prevail. Any deviation between the net asset value per share of such exchange-traded fund and its trading price could create other risks for a fund if it held a short position in the securities of such an exchange-traded fund. Such other risks include the possibility of a larger loss on the short position than would otherwise be the case, the reduced likelihood that the intended benefit of the short position will achieve its objective(s), and the increased likelihood of a demand to replace the borrowed security at a time when obtaining such replacement security may be difficult or impossible at a reasonable price.

Until the security is replaced, the Fund is required to pay to the lender amounts equal to any dividends or interest that accrue during the period of the loan. To borrow the security, the Fund also may be required to pay a premium, which would increase the cost of the security sold. The proceeds of the short sale, and potentially additional margin, will be retained by the broker from whom the security is borrowed, to the extent necessary to meet margin requirements, until the short position is closed out. The amount of any potential gain will be decreased, and the amount of any potential loss increased, by the amount of any premium or amounts in lieu of interest that the Fund may be required to pay in connection with a short sale.

Until the Fund replaces a borrowed security in connection with a short sale, the Fund will be required to segregate liquid assets (constituting cash, cash equivalents, or other liquid portfolio securities) at such a level that: (i) the amount segregated plus the amount deposited with the broker as collateral will at all times be equal to at least 100% of the current value of the security sold short and (ii) the amount segregated plus the amount deposited with the broker as collateral will not be less than the market value of the security at the time it was sold short. Consequently, in the event of an increase in the price of a security in which a fund has a short position, it may have to increase the amount of collateral to be posted and may have to sell other securities in the portfolio to be able to do so. In times of market stress, making such sales may be difficult to do because of limited and declining liquidity.

Short-Term Debt Instruments and Temporary Investments

Optimum Large Cap Growth Fund, Optimum Large Cap Value Fund, Optimum Small-Mid Cap Growth Fund, Optimum Small-Mid Cap Value Fund and Optimum Fixed Income Fund reserve the right to invest without limitation in cash, money market instruments or high quality short-term debt securities, including repurchase agreements, for temporary defensive purposes. Optimum International Fund reserves the right to invest without limitation in US

securities, cash, money market instruments or high quality short-term debt securities, including repurchase agreements, for temporary defensive purposes. A Fund may, from time to time, invest all or part of its available assets in money market instruments maturing in one year or less. The types of instruments that a Fund may purchase are described below:

US Government Securities. Examples of types of US government obligations in which a Fund may invest include US Treasury obligations and the obligations of US government agencies such as Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the US, Small Business Administration, Fannie Mae, Ginnie Mae, General Services Administration, Student Loan Marketing Association, Central Bank for Cooperatives, Freddie Mac, Federal Intermediate Credit Banks, Maritime Administration, and other similar agencies. Whether backed by the full faith and credit of the US Treasury or not, US government securities are not guaranteed against price movements due to fluctuating interest rates.

Commercial Paper. Commercial paper is the term used to designate unsecured short-term promissory notes issued by corporations and other entities. Maturities on these issues vary from a few to 270 days. A Fund may invest in short-term promissory notes issued by corporations that, at the time of purchase, are rated P-1 and/or A-1. Commercial paper ratings P-1 by Moody’s and A-1 by S&P are the highest investment grade category.

Obligations of Domestic Banks, Foreign Banks and Foreign Branches of US Banks. A Fund may invest in obligations issued by banks and other savings institutions. Investments in bank obligations include obligations of domestic branches of foreign banks and foreign branches of domestic banks. Such investments in domestic branches of foreign banks and foreign branches of domestic banks are not covered by the Federal Deposit Insurance Corporation (“FDIC”) and may involve risks that are different from investments in securities of domestic branches of US banks. These risks may include future unfavorable political and economic developments, possible withholding taxes on interest income, seizure or nationalization of foreign deposits, currency controls, interest limitations, or other governmental restrictions that might affect the payment of principal or interest on the securities held by a Fund. Additionally, these institutions may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping requirements than those applicable to domestic branches of US banks. Bank obligations include the following:

Small to Medium-Sized Companies

The Funds may invest in equity securities of small to medium-sized companies. These stocks have historically been more volatile in price than larger capitalization stocks, such as those included in the S&P 500​® Index. This is because, among other things, smaller companies have a lower degree of liquidity and tend to have a greater sensitivity to changing economic conditions. These companies may have narrow product lines, markets or financial resources, or may depend on a limited management group. In addition, these companies are typically subject to a greater degree of change in their earnings and prospects. The companies’ securities may trade less frequently and have a smaller trading volume. The securities may be traded only in the

over-the-counter markets or on a regional securities exchange. In addition to exhibiting greater volatility, smaller capitalization securities may, to some degree, fluctuate independently of the stocks of larger capitalization companies. For example, the stocks of smaller capitalization companies may decline in price as the price of larger company stocks rise, or vice versa.

Special Situations

A Fund may use aggressive investment techniques, including seeking to benefit from “special situations,” such as mergers, reorganizations, investing in small-size companies, or other unusual events expected to affect a particular issuer. There is a risk that the “special situation” might not occur, which could have a negative impact on the price of the issuer’s securities and fail to produce the expected gains or produce a loss for the Fund.

Standby Commitments

These instruments, which are similar to a put, give a Fund the option to obligate a broker, dealer or bank to repurchase a security held by that Fund at a specified price.

There is no guarantee that the securities subject to a standby commitment agreement will be issued or, if such securities are issued, the value of the securities on the date of issuance may be more or less than the purchase price. A Fund will limit its investments in standby commitment agreements with remaining terms exceeding seven days pursuant to the limitation on investments in illiquid investments. A Fund will record the purchase of a standby commitment agreement, and will reflect the value of the security in the Fund’s NAV, on the date on which the security can reasonably be expected to be issued.

Structured Products

The Funds may invest in structured products, including instruments such as credit-linked securities, commodity-linked notes and structured notes, which are potentially high-risk derivatives. Structured products (a type of potentially high-risk derivative) that the Funds may invest in have been developed and combine the elements of futures contracts or options with those of debt, preferred equity, or a depository instrument (hereinafter “structured products”). Generally, a structured product will be a debt security, preferred stock, depository share, trust certificate, certificate of deposit, or other evidence of indebtedness on which a portion of or all interest payments, and/or the principal or stated amount payable at maturity, redemption, or retirement is determined by reference to prices, changes in prices, or differences between prices of securities, currencies, intangibles, goods, articles, or commodities (collectively “underlying assets”) or by another objective index, economic factor, or other measure, such as interest rates, currency exchange rates, commodity indices, and securities indices (collectively “benchmarks”). Thus, structured products may take a variety of forms, including, but not limited to, debt instruments with interest or principal payments or redemption terms determined by reference to the value of a currency or commodity or securities index at a future point in time, preferred stock with dividend rates determined by reference to the value of a currency, or convertible securities with the conversion terms related to a particular commodity.

Structured products can be an efficient means of creating exposure to a particular market, or segment of a market, with the objective of enhancing total return. For example, a Fund may wish to take advantage of expected declines in interest rates in several European countries, but avoid the transaction costs associated with buying and currency-hedging the foreign bond positions. One solution would be to purchase a US dollar-denominated structured product whose redemption price is linked to the average 3-year interest rate in a designated group of countries. The redemption price formula would provide for payoffs of greater than par if the average interest rate were lower than a specified level, and payoffs of less than par if rates were above the specified level. Furthermore, a Fund could limit the downside risk of the security by establishing a minimum redemption price so that the principal paid at maturity could not be below a predetermined minimum level if interest rates were to rise significantly. The purpose of this arrangement, known as a structured security with an embedded put option, would be to give the Fund the desired European bond exposure while avoiding currency risk, limiting downside market risk, and lowering transaction costs. Of course, there is no guarantee that the strategy will be successful, and a Fund could lose money if, for example, interest rates do not move as anticipated or credit problems develop with the issuer of the structured products.

The risks of investing in structured products reflect a combination of the risks of investing in securities, options, futures, and currencies. Thus, an investment in a structured product may entail significant risks that are not associated with a similar investment in a traditional debt instrument that has a fixed principal amount, is denominated in US dollars, or bears interest either at a fixed rate or a floating rate determined by reference to a common, nationally published benchmark. The risks of a particular structured product will, of course, depend upon the terms of the instrument, but may include, without limitation, the possibility of significant changes in the benchmarks or the prices of underlying assets to which the instrument is linked. Such risks generally depend upon factors that are unrelated to the operations or credit quality of the issuer of the structured product and that may not be readily foreseen by the purchaser, such as economic and political events, the supply of and demand for the underlying assets, and interest rate movements. In recent years, various benchmarks and prices for underlying assets have been highly volatile, and such volatility may be expected in the future. Reference is also made to the discussion of futures, options, and forward contracts herein for a discussion of the risks associated with such investments.

Structured products are potentially more volatile and carry greater market risks than traditional debt instruments. Depending on the construction of the particular structured product, changes in a benchmark may be magnified by the terms of the structured product and have an even more dramatic and substantial effect upon the value of the structured product. Also, the prices of the structured product and the benchmark or underlying asset may not move in the same direction or at the same time.

Structured products may bear interest or pay preferred dividends at below market (or even relatively nominal) rates. Alternatively, structured products may bear interest at above market rates but bear an increased risk of principal loss (or gain). The latter scenario may result if “leverage” is used to make up the structured product. Leverage risk occurs when the structured product is organized so that a given change in a benchmark or underlying asset is multiplied to produce a greater value change in the structured product, thereby magnifying the risk of loss as well as the potential for gain.

Structured products may also carry liquidity risk since the instruments are often “customized” to meet the portfolio needs of a particular investor, and therefore, the number of investors that are willing and able to buy such instruments in the secondary market may be smaller than that for more traditional debt securities. In addition, because the purchase and sale of structured products could take place in an over-the-counter market without the guarantee of a central clearing organization or in a transaction between a Fund and the issuer of the structured product, the creditworthiness of the counterparty or issuer of the structured product would be an additional risk factor which the Fund would have to consider and monitor. Structured products also may not be subject to regulation by the CFTC, which generally regulates the trading of commodity futures by US persons, the SEC, which regulates the offer and sale of securities by and to US persons, or any other governmental regulatory authority.

The various risks discussed above, particularly the market risk of such instruments, may in turn cause significant fluctuations in the NAV of a Fund. Certain issuers of structured products may be deemed to be investment companies as defined in the 1940 Act. As a result, the Funds’ investments in these structured products may be subject to limits applicable to investments in investment companies and may be subject to restrictions contained in the 1940 Act.

Credit-Linked Securities. Credit-linked securities are issued by a limited purpose trust or other vehicle that, in turn, invests in a basket of derivatives instruments, such as credit default swaps, interest rate swaps and other securities, in order to provide exposure to certain high yield or other fixed income markets. For example, a Fund may invest in credit-linked securities as a cash management tool in order to gain exposure to the high yield markets and/or to remain fully invested when more traditional income-producing securities are not available. Like an investment in a bond, investments in credit-linked securities represent the right to receive periodic income payments (in the form of distributions) and payment of principal at the end of the term of the security. However, these payments are conditioned on the trust’s receipt of payments from, and the trust’s potential obligations to, the counterparties to the derivatives instruments and other securities in which the trust invests. For instance, the trust may sell one or more credit default swaps, under which the trust would receive a stream of payments over the term of the swap agreements provided that no event of default has occurred with respect to the referenced debt obligation upon which the swap is based. If a default occurs, the stream of payments may stop and the trust would be obligated to pay the counterparty the par (or other agreed upon value) of the referenced debt obligation. This, in turn, would reduce the amount of income and principal that a Fund would receive as an investor in the trust. A Fund’s investments in these instruments are indirectly subject to the risks associated with derivatives instruments, including, among others, credit risk, default or similar event risk, counterparty risk, interest rate risk, leverage risk and management risk. It is expected that the securities will be exempt from registration under the 1933 Act. Accordingly, there may be no established trading market for the securities and they may constitute illiquid investments.

Swaps

A Fund may enter into credit default, currency, total return and interest rate swaps and the purchase or sale of related caps, floors and collars. It is expected that a Fund will enter into these transactions primarily to preserve a return or spread on a particular investment or portion of its portfolio, to protect against currency fluctuations, as a duration management technique or to protect against any increase in the price of securities the Fund anticipates purchasing at a later date. It also is expected that a Fund will use these transactions as hedges and not speculative investments and will not sell interest rate caps or floors where it does not own securities or other instruments providing the income stream the Fund may be obligated to pay. The purchase of a cap entitles the purchaser to receive payments on a notional principal amount from the party selling such cap to the extent that a specified index exceeds a predetermined interest rate or amount. The purchase of a floor entitles the purchaser to receive payments on a notional principal amount from the party selling such floor to the extent that a specified index falls below a predetermined interest rate or amount. A collar is a combination of a cap and a floor that preserves a certain return within a predetermined range of interest rates or values.

A Fund will usually enter into swaps on a net basis, i.e., the two payment streams are netted out in a cash settlement on the payment date or dates specified in the instrument, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. Inasmuch as these swaps, caps, floors and collars are entered into for good faith hedging purposes, the investment adviser and the Funds believe that such obligations do not constitute senior securities under the 1940 Act and, accordingly, will not treat them as being subject to their borrowing restrictions. A Fund will not be permitted to enter into any swap, cap, floor or collar transaction unless, at the time of entering into such transaction, the unsecured long-term debt of the counterparty, combined with any credit enhancements, is rated at least BBB- by S&P or Baa3 by Moody’s or is determined to be of equivalent credit quality by the investment adviser. If there is a default by the counterparty, a Fund may have contractual remedies pursuant to the agreements related to the transaction. The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, the swap market has become relatively liquid. Caps, floors and collars are more recent innovations for which standardized documentation has not yet been fully developed and, accordingly, they are less liquid than swaps.

Comprehensive swaps regulation. The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) and related regulatory developments have imposed comprehensive regulatory requirements on swaps and swap market participants. This regulatory framework includes: (1) registration and regulation of swap dealers and major swap participants; (2) requiring central clearing and execution of standardized swaps; (3) imposing margin requirements on swap transactions; (4) regulating and monitoring swap transactions through position limits and large trader reporting requirements;

and (5) imposing record keeping and centralized and public reporting requirements, on an anonymous basis. The CFTC is responsible for the regulation of most swaps. The SEC has jurisdiction over a small segment of the market referred to as “security-based swaps,” which includes swaps on single securities or credits, or narrow-based indices of securities or credits.

Uncleared swaps. In an uncleared swap, the swap counterparty is typically a brokerage firm, bank, or other financial institution. A Fund customarily enters into uncleared swaps based on the standard terms and conditions of an International Swaps and Derivatives Association (“ISDA”) Master Agreement. ISDA is a voluntary industry association of participants in the over-the-counter derivatives markets that has developed standardized contracts used by such participants that have agreed to be bound by such standardized contracts.

In the event that one party to a swap transaction defaults and the transaction is terminated prior to its scheduled termination date, one of the parties may be required to make an early termination payment to the other. An early termination payment may be payable by either the defaulting or nondefaulting party, depending upon which of them is “in-the-money” with respect to the swap at the time of its termination. Early termination payments may be calculated in various ways, but are intended to approximate the amount the “in-the-money” party would have to pay to replace the swap as of the date of its termination.

During the term of an uncleared swap, a Fund is required to pledge to the swap counterparty, from time to time, an amount of cash and/or other assets, referred to as “variation margin,” that is equal to the total net amount (if any) that would be payable by the Fund to the counterparty if all outstanding swaps between the parties were terminated on the date in question, including any early termination payments. Periodically, changes in the variation margin amount are made to recognize changes in value of the contract resulting from, among other things, interest on the notional value of the contract, market value changes in the underlying investment, and/or dividends paid by the issuer of the underlying instrument. Likewise, the counterparty will be required to pledge cash or other assets to cover its obligations to a Fund. However, the amount pledged may not always be equal to or more than the amount due to the other party. Therefore, if a counterparty defaults on its obligations to a Fund, the amount pledged by the counterparty and available to the Fund may not be sufficient to cover all the amounts due to the Fund and the Fund may sustain a loss.

Currently, a Fund does not typically provide initial margin in connection with uncleared swaps. However, rules requiring initial margin to be posted by certain market participants for uncleared swaps have been adopted and are being phased in over time. When these rules take effect with respect to a Fund, if a Fund is deemed to have material swaps exposure under applicable swaps regulation, it will be required to post initial margin in addition to variation margin.

Cleared swaps. Certain standardized swaps are subject to mandatory central clearing and exchange trading. The Dodd-Frank Act and implementing rules will ultimately require the clearing and exchange-trading of many swaps. Mandatory exchange-trading and clearing will occur on a phased-in basis based on the type of market participant, CFTC approval of contracts for central clearing, and public trading facilities making such cleared swaps available to trade. To date, the CFTC has designated only certain of the most common types of credit default index swaps and interest rate swaps as subject to mandatory clearing and certain public trading facilities have made certain of those cleared swaps available to trade, but it is expected that additional categories of swaps will in the future be designated as subject to mandatory clearing and trade execution requirements. Central clearing is intended to reduce counterparty credit risk and increase liquidity, but central clearing does not eliminate these risks and may involve additional costs and risks not involved with uncleared swaps. For more information, see “Risks of cleared swaps” below.

In a cleared swap, a Fund’s ultimate counterparty is a central clearinghouse rather than a brokerage firm, bank, or other financial institution. Cleared swaps are submitted for clearing through each party’s FCM, which must be a member of the clearinghouse that serves as the central counterparty.

When a Fund enters into a cleared swap, it must deliver to the central counterparty (via the FCM) an amount referred to as “initial margin.” Initial margin requirements are determined by the central counterparty, but an FCM may require additional initial margin above the amount required by the central counterparty. During the term of the swap agreement, a “variation margin” amount may also be required to be paid by a Fund or may be received by the Fund in accordance with margin controls set for such accounts, depending upon changes in the marked-to-market value of the swap agreement. At the conclusion of the term of the swap agreement, if a Fund has a loss equal to or greater than the margin amount, the margin amount is paid to the FCM along with any loss in excess of the margin amount. If a Fund has a loss of less than the margin amount, the excess margin is returned to the Fund. If a Fund has a gain, the full margin amount and the amount of the gain are paid to the Fund.

Recently adopted CFTC rules require the trading and execution of certain cleared swaps on public trading facilities. Trading on an exchange-type system may increase market transparency and liquidity but may require a Fund to incur increased expenses to access the same types of swaps that it has used in the past.

Credit default swaps. The “buyer” of protection in a credit default swap agreement is obligated to pay the “seller” a periodic stream of payments over the term of the agreement in return for a payment by the “seller” that is contingent upon the occurrence of a credit event with respect to a specific underlying reference debt obligation (whether as a single debt instrument or as part of an index of debt instruments). The contingent payment by the seller generally is the face amount of the debt obligation, in return for the buyer’s obligation to make periodic cash payments and deliver in physical form the reference debt obligation or a cash payment equal to the then-current market value of that debt obligation at the time of the credit event. If no credit event occurs, the seller would receive a fixed rate of income throughout the term of the contract, while the buyer would lose the amount of its payments and recover nothing. The buyer is also subject to the risk that the seller will not satisfy its contingent payment obligation, if and when due.

Purchasing protection through a credit default swap may be used to attempt to hedge against a decline in the value of debt security or securities due to a credit event. The seller of protection under a credit default swap receives periodic payments from the buyer but is exposed to the risk that the value of the reference debt obligation declines due to a credit event and that it will have to pay the face amount of the reference obligation to the buyer. Selling protection

under a credit default swap may also permit the seller to gain exposure that is similar to owning the reference debt obligation directly. As the seller of protection, a Fund would effectively add leverage to its portfolio because, in addition to its total assets, the Fund would be subject to the risk that there would be a credit event and the Fund would have to make a substantial payment in the future.

Generally, a credit event means bankruptcy, failure to timely pay interest or principal, obligation acceleration default, or repudiation or restructuring of the reference debt obligation. There may be disputes between the buyer or seller of a credit default swap agreement or within the swaps market as a whole as to whether or not a credit event has occurred or what the payout should be which could result in litigation. In some instances where there is a dispute in the credit default swap market, a regional Determinations Committee set up by ISDA may make an official binding determination regarding the existence of credit events with respect to the reference debt obligation of a credit default swap agreement or, in the case of a credit default swap on an index, with respect to a component of the index underlying the credit default swap agreement. In the case of a credit default swap on an index, the existence of a credit event is determined according to the index methodology, which may in turn refer to determinations made by ISDA’s Determinations Committees with respect to particular components of the index.

ISDA’s Determinations Committees are comprised principally of dealers in the OTC derivatives markets which may have a conflicting interest in the determination regarding the existence of a particular credit event. In addition, in the sovereign debt market, a credit default swap agreement may not provide the protection generally anticipated because the government issuer of the sovereign debt instruments may be able to restructure or renegotiate the debt in such a manner as to avoid triggering a credit event. Moreover, (1) sovereign debt obligations may not incorporate common, commercially acceptable provisions, such as collective action clauses, or (2) the negotiated restructuring of the sovereign debt may be deemed non-mandatory on all holders. As a result, the Determinations Committees might then not be able to determine, or may be able to avoid having to determine, that a credit event under the credit default agreement has occurred. For these and other reasons, the buyer of protection in a credit default swap agreement is subject to the risk that certain occurrences, such as particular restructuring events affecting the value of the underlying reference debt obligation, or the restructuring of sovereign debt, may not be deemed credit events under the credit default swap agreement. Therefore, if the credit default swap was purchased as a hedge or to take advantage of an anticipated increase in the value of credit protection for the underlying reference obligation, it may not provide any hedging benefit or otherwise increase in value as anticipated. Similarly, the seller of protection in a credit default swap agreement is subject to the risk that certain occurrences may be deemed to be credit events under the credit default swap agreement, even if these occurrences do not adversely impact the value or creditworthiness of the underlying reference debt obligation.

Currency swaps. A currency swap is an agreement between two parties to exchange periodic cash flows on a notional amount of two or more currencies based on the relative value differential between them. For example, a currency swap may involve the exchange of payments in a non-US currency for payments in US dollars. Currency swaps typically involve the delivery of the entire notional values of the two designated currencies. In such a situation, the full notional value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. A Fund may also enter into currency swaps on a net basis, which means the two different currency payment streams under the swap agreement are converted and netted out to a single cash payment in just one of the currencies. For example, a currency swap may be used to hedge the interest payments and principal amount of a debt obligation that is denominated in a non-US currency by entering into a cross currency swap whereby one party would make payments in the non-US currency and receive payments in US dollars. Or, a currency swap may be used to gain exposure to non-US currencies and non-US interest rates by making payments in US dollars and receiving payments in non-US currencies.

Because currency control is of great importance to the issuing governments and influences economic planning and policy, purchases and sales of currency and related instruments can be negatively affected by government exchange controls, blockages, and manipulations or exchange restrictions imposed by governments. These actions could result in losses to a Fund if it is unable to deliver or receive a specified currency or funds in settlement of obligations, including swap transaction obligations. These actions could also have an adverse effect on a Fund’s swap transactions or cause a Fund’s hedging positions to be rendered useless, resulting in full currency exposure as well as incurring unnecessary transaction costs.

Index swaps. An index swap, also called a total return swap, is an agreement between two parties in which a party typically exchanges a cash flow based on a notional amount of a reference index for a cash flow based on a different index or on another specified instrument or reference rate. Index swaps are generally entered into on a net basis. In an index swap, a fund receives gains or incurs losses based on the total return of a specified index, in exchange for making interest payments to another party. An index swap can also work in reverse with a fund receiving interest payments from another party in exchange for movements in the total return of a specified index.

Interest rate swaps. An interest rate swap is an agreement between two parties to exchange interest rate payment obligations. Each party’s payment obligation under an interest rate swap is determined by reference to a specified “notional” amount of money. Therefore, interest rate swaps generally do not involve the delivery of securities, other underlying instruments, or principal amounts; rather they entail the exchange of cash payments based on the application of the designated interest rates to the notional amount. Accordingly, barring swap counterparty or FCM default, the risk of loss in an interest rate swap is limited to the net amount of interest payments that a Fund is obligated to make or receive (as applicable), as well as any early termination payment payable by or to a Fund upon early termination of the swap.

By swapping fixed interest rate payments for floating interest rate payments, an interest rate swap can be used to increase or decrease a Fund’s exposure to various interest rates, including to hedge interest rate risk. Interest rate swaps are generally used to permit the party seeking a floating-rate obligation the opportunity to acquire such obligation at a rate lower than is directly available in the credit markets, while permitting the party desiring a fixed-rate obligation the opportunity to acquire such a fixed-rate obligation, also frequently at a rate lower than is directly available in the credit markets. The success of such a

transaction depends in large part on the availability of fixed-rate obligations at interest (or coupon) rates low enough to cover the costs involved. An interest rate swap transaction is affected by changes in interest rates, which, in turn, may affect the prepayment rate of any underlying debt obligations upon which the interest rate swap is based.

Risks of swaps generally. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether a Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Manager to predict correctly which types of investments are likely to produce greater returns. If the Manager, in using swap agreements, is incorrect in its forecasts of market values, interest rates, inflation, currency exchange rates or other applicable factors, the investment performance of a Fund will be less than its performance would have been if it had not used the swap agreements.

The risk of loss to a Fund for swap transactions that are entered into on a net basis depends on which party is obligated to pay the net amount to the other party. If the counterparty is obligated to pay the net amount to a Fund, the risk of loss to the Fund is loss of the entire amount that the Fund is entitled to receive. If a Fund is obligated to pay the net amount, the Fund’s risk of loss is generally limited to that net amount. If the swap agreement involves the exchange of the entire principal value of a security, the entire principal value of that security is subject to the risk that the other party to the swap will default on its contractual delivery obligations. In addition, a Fund’s risk of loss also includes any margin at risk in the event of default by the counterparty (in an uncleared swap) or the central counterparty or FCM (in a cleared swap), plus any transaction costs.

Because bilateral swap agreements are structured as two-party contracts and may have terms of greater than seven days, these swaps may be considered to be illiquid and, therefore, subject to a Fund’s limitation on investments in illiquid investments. If a swap transaction is particularly large or if the relevant market is illiquid, a Fund may not be able to establish or liquidate a position at an advantageous time or price, which may result in significant losses. Participants in the swap markets are not required to make continuous markets in the swap contracts they trade. Participants could refuse to quote prices for swap contracts or quote prices with an unusually wide spread between the price at which they are prepared to buy and the price at which they are prepared to sell. Some swap agreements entail complex terms and may require a greater degree of subjectivity in their valuation. However, the swap markets have grown substantially in recent years, with a large number of financial institutions acting both as principals and agents, utilizing standardized swap documentation. As a result, the swap markets have become increasingly liquid. In addition, central clearing and the trading of cleared swaps on public facilities are intended to increase liquidity. The Manager, under the supervision of the Board, is responsible for determining and monitoring the liquidity of the Funds’ swap transactions.

Rules adopted under the Dodd-Frank Act require centralized reporting of detailed information about many swaps, whether cleared or uncleared. This information is available to regulators and also, to a more limited extent and on an anonymous basis, to the public. Reporting of swap data is intended to result in greater market transparency. This may be beneficial to funds that use swaps in their trading strategies. However, public reporting imposes additional recordkeeping burdens on these funds, and the safeguards established to protect anonymity are not yet tested and may not provide protection of funds’ identities as intended.

Certain Internal Revenue Service (“IRS”) positions may limit a Fund’s ability to use swap agreements in a desired tax strategy. It is possible that developments in the swap markets and/or the laws relating to swap agreements, including potential government regulation, could adversely affect a Fund’s ability to benefit from using swap agreements, or could have adverse tax consequences. For more information about potentially changing regulation, see “Developing government regulation of derivatives” above.

Risks of uncleared swaps. Uncleared swaps are not traded on exchanges. As a result, swap participants may not be as protected as participants on organized exchanges. Performance of a swap agreement is the responsibility only of the swap counterparty and not of any exchange or clearinghouse. As a result, a Fund is subject to the risk that a counterparty will be unable or will refuse to perform under such agreement, including because of the counterparty’s bankruptcy or insolvency. A Fund risks the loss of the accrued but unpaid amounts under a swap agreement, which could be substantial, in the event of a default, insolvency, or bankruptcy by a swap counterparty. In such an event, a Fund will have contractual remedies pursuant to the swap agreements, but bankruptcy and insolvency laws could affect the Fund’s rights as a creditor. If the counterparty’s creditworthiness declines, the value of a swap agreement would likely decline, potentially resulting in losses. The Manager will only approve a swap agreement counterparty for a Fund if the Manager deems the counterparty to be creditworthy under the Fund’s counterparty review process. However, in unusual or extreme market conditions, a counterparty’s creditworthiness and ability to perform may deteriorate rapidly, and the availability of suitable replacement counterparties may become limited.

Risks of cleared swaps. As noted above, under recent financial reforms, certain types of swaps are, and others eventually are expected to be, required to be cleared through a central counterparty, which may affect counterparty risk and other risks faced by a Fund.

Central clearing is designed to reduce counterparty credit risk and increase liquidity compared to uncleared swaps because central clearing interposes the central clearinghouse as the counterparty to each participant’s swap, but it does not eliminate those risks completely. There is also a risk of loss by a Fund of the initial and variation margin deposits in the event of bankruptcy of the FCM with which the Fund has an open position in a swap contract. The assets of a Fund may not be fully protected in the event of the bankruptcy of the FCM or central counterparty because the Fund might be limited to recovering only a pro rata share of all available funds and margin segregated on behalf of an FCM’s customers. If the FCM does not provide accurate reporting, a Fund is also subject to the risk that the FCM could use the Fund’s assets, which are held in an omnibus account with assets belonging to the FCM’s other customers, to satisfy its own financial obligations or the payment obligations of another customer to the central counterparty. Credit risk of cleared swap participants is concentrated in a few clearinghouses, and the consequences of insolvency of a clearinghouse are not clear.

With cleared swaps, a Fund may not be able to obtain as favorable terms as it would be able to negotiate for a bilateral, uncleared swap. In addition, an FCM may unilaterally amend the terms of its agreement with the Fund, which may include the imposition of position limits or additional margin requirements with respect to a Fund’s investment in certain types of swaps. Central counterparties and FCMs can require termination of existing cleared swap transactions upon the occurrence of certain events, and can also require increases in margin above the margin that is required at the initiation of the swap agreement. Currently, depending on a number of factors, the margin required under the rules of the clearinghouse and FCM may be in excess of the collateral required to be posted by a Fund to support its obligations under a similar uncleared swap. However, regulators have adopted rules imposing margin requirements on uncleared swaps, which will become effective as to various market participants over time.

Finally, a Fund is subject to the risk that, after entering into a cleared swap, no FCM or central counterparty is willing or able to clear the transaction. In such an event, a Fund may be required to break the trade and make an early termination payment.

Trade Claims

The Funds may purchase trade claims and similar obligations or claims against companies in bankruptcy proceedings. Trade claims are non-securitized rights of payment arising from obligations that typically arise when vendors and suppliers extend credit to a company by offering payment terms for products and services. If the company files for bankruptcy, payments on these trade claims stop and the claims are subject to compromise along with the other debts of the company. Trade claims may be purchased directly from the creditor or through brokers. There is no guarantee that a debtor will ever be able to satisfy its trade claim obligations. Trade claims are subject to the risks associated with low-quality obligations.

Trust Preferred Securities

The Funds may invest in trust preferred securities. Trust preferred securities have the characteristics of both subordinated debt and preferred stock. Generally, trust preferred securities are issued by a trust that is wholly owned by a financial institution or other corporate entity, typically a bank holding company. The financial institution creates the trust and owns the trust’s common securities. The trust uses the sale proceeds of its common securities to purchase subordinated debt issued by the financial institution. The financial institution uses the proceeds from the subordinated debt sale to increase its capital while the trust receives periodic interest payments from the financial institution for holding the subordinated debt. The trust uses the funds received to make dividend payments to the holders of the trust preferred securities. The primary advantage of this structure is that the trust preferred securities are treated by the financial institution as debt securities for tax purposes and as equity for the calculation of capital requirements.

Trust preferred securities typically bear a market rate coupon comparable to interest rates available on debt of a similarly rated issuer. Typical characteristics include long-term maturities, early redemption by the issuer, periodic fixed or variable interest payments, and maturities at face value. Holders of trust preferred securities have limited voting rights to control the activities of the trust and no voting rights with respect to the financial institution. The market value of trust preferred securities may be more volatile than those of conventional debt securities. Trust preferred securities may be issued in reliance on Rule 144A under the 1933 Act and subject to restrictions on resale. There can be no assurance as to the liquidity of trust preferred securities and the ability of holders, such as a Fund, to sell their holdings. The condition of the financial institution is looked at to identify the risks of the trust preferred securities as the trust typically has no business operations other than to issue the trust preferred securities. If the financial institution defaults on interest payments to the trust, the trust will not be able to make dividend payments to holders of its securities, such as a Fund.

Unseasoned Companies

The Funds may invest in relatively new or unseasoned companies.

New or unseasoned companies are in their early stages of development, or small companies positioned in new and emerging industries where the opportunity for rapid growth is expected to be above average. Securities of unseasoned companies present greater risks than securities of larger, more established companies. These companies may have relatively small revenues, limited product lines, and may have a small share of the market for their products or services. Small companies may lack depth of management, they may be unable to internally generate funds necessary for growth or potential development or to generate such funds through external financing or on favorable terms, or they may be developing or marketing new products or services for which markets are not yet established and may never become established. Due to these and other factors, small companies may suffer significant losses as well as realize substantial growth, and investments in such companies tend to be volatile and are therefore speculative.

US Government Securities

US government securities include obligations of, or guaranteed by, the US federal government, its agencies, instrumentalities, or sponsored enterprises. Some US government securities are supported by the full faith and credit of the US government. These include US Treasury obligations and securities issued by Ginnie Mae. A second category of US government securities is those supported by the right of the agency, instrumentality or sponsored enterprise to borrow from the US government to meet its obligations. These include securities issued by Federal Home Loan Banks.

A third category of US government securities is those supported by only the credit of the issuing agency, instrumentality, or sponsored enterprise. These include securities issued by Fannie Mae and Freddie Mac. In the event of a default, an investor like a Fund would only have legal recourse to the issuer, not the US government. Although the US government has provided support for these securities in the past, there can be no assurance that it will do so in the future. The US government has also made available additional guarantees for limited periods to stabilize or restore a market in the wake of an economic,

political, or natural crisis. Such guarantees, and the economic opportunities they present, are likely to be temporary and cannot be relied upon by a Fund. Any downgrade of the credit rating of the securities issued by the US government may result in a downgrade of securities issued by its agencies or instrumentalities, including government-sponsored entities.

Variable and Floating Rate Notes

Variable-rate master demand notes, in which a Fund may invest, are unsecured demand notes that permit the indebtedness thereunder to vary and provide for periodic adjustments in the interest rate according to the terms of the instrument. Because master demand notes are direct lending arrangements between a Fund and the issuer, they are not normally traded. Although there is no secondary market in the notes, a Fund may demand payment of principal and accrued interest at any time. Although the notes are not typically rated by credit rating agencies, issuers of variable amount master demand notes (which are normally manufacturing, retail, financial, and other business concerns) must satisfy the same criteria as set forth above for commercial paper. In determining average weighted portfolio maturity, a variable amount master demand note will be deemed to have a maturity equal to the period of time remaining until the principal amount can be recovered from the issuer through demand.

A variable-rate note is one whose terms provide for the adjustment of its interest rate on set dates and which, upon such adjustment, can reasonably be expected to have a market value that approximates its par value. A floating-rate note is one whose terms provide for the adjustment of its interest rate whenever a specified interest rate changes and which, at any time, can reasonably be expected to have a market value that approximates its par value. Such notes are frequently not rated by credit rating agencies; however, unrated variable- and floating-rate notes purchased by a Fund will be determined by the Manager under guidelines established by the Board to be of comparable quality at the time of purchase to rated instruments eligible for purchase under the Fund’s investment policies. In making such determinations, the Manager will consider the earning power, cash flow, and other liquidity ratios of the issuers of such notes (such issuers include financial, merchandising, bank holding, and other companies) and will continuously monitor their financial condition. Although there may be no active secondary market with respect to a particular variable- or floating-rate note purchased by a Fund, the Fund may resell the note at any time to a third party. The absence of such an active secondary market, however, could make it difficult for a Fund to dispose of the variable- or floating-rate note involved in the event the issuer of the note defaulted on its payment obligations, and the Fund could, for this or other reasons, suffer a loss to the extent of the default. Variable- or floating-rate notes may be secured by bank letters of credit.

If not rated, such instruments must be found by the Manager under guidelines established by the Board, to be of comparable quality to instruments that are rated high quality. A rating may be relied upon only if it is provided by a NRSRO that is not affiliated with the issuer or guarantor of the instruments. See “Appendix A — Description of Ratings” for a description of the rating symbols of S&P and Moody’s.

Warrants

Each Fund may purchase or sell warrants and similar rights, which are privileges issued by corporations enabling the owners to subscribe to and purchase a specified number of shares of the corporation at a specified price during a specified period of time. The purchase of warrants involves the risk that the Fund could lose the purchase value of a warrant if the right to subscribe to additional shares is not exercised prior to the warrant’s expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the related security may exceed the value of the subscribed security’s market price such as when there is no movement in the level of the underlying security.

When-Issued and Delayed-Delivery Securities

Each Fund may purchase securities on a when-issued or delayed-delivery basis. In such transactions, instruments are purchased with payment and delivery taking place in the future in order to secure what is considered to be an advantageous yield or price at the time of the transaction. Delivery of and payment for these securities may take up to a month after the date of the purchase commitment, although in some cases it may take longer. The payment obligation and the interest rates that will be received are each fixed at the time the Fund enters into the commitment and no interest accrues to the Fund until settlement. Thus, it is possible that the market value at the time of settlement could be higher or lower than the purchase price if the general level of interest rates has changed.

Zero Coupon and Payment-In-Kind Bonds

The Funds may invest in zero coupon bonds or payment-in-kind bonds.

The credit risk factors pertaining to lower-rated securities also apply to lower-rated zero coupon, deferred interest, and payment-in-kind bonds. These bonds carry an additional risk in that, unlike bonds that pay interest throughout the period to maturity, a Fund will realize no cash until the cash payment date and, if the issuer defaults, the Fund may obtain no return at all on its investment.

Zero coupon, deferred interest, and payment-in-kind bonds involve additional special considerations. Zero coupon or deferred interest securities are debt obligations that do not entitle the holder to any periodic payments of interest prior to maturity or a specified date when the securities begin paying current interest (the “cash payment date”) and therefore are generally issued and traded at a discount from their face amounts or par values. The discount varies depending on the time remaining until maturity or cash payment date, prevailing interest rates, liquidity of the security, and the perceived credit quality of the issuer. The discount, in the absence of financial difficulties of the issuer, typically decreases as the final maturity or cash payment date of the security approaches. The market prices of zero coupon securities are generally more volatile than the market prices of securities that pay interest periodically and are likely to respond to changes in interest rates to a greater degree than do non-zero coupon or deferred interest securities having similar maturities and credit

quality. Current federal income tax law requires that a holder of a zero coupon security report as income each year the portion of the original issue discount on the security that accrues that year, even though the holder receives no cash payments of interest during the year.

Payment-in-kind bonds are securities that pay interest through the issuance of additional bonds. A Fund will be deemed to receive interest over the life of these bonds and be treated as if interest were paid on a current basis for federal income tax purposes, although no cash interest payments are received by the Fund until the cash payment date or until the bonds mature. Accordingly, during periods when a Fund receives no cash interest payments on its zero coupon securities or deferred interest or payment-in-kind bonds, it may be required to dispose of portfolio securities to meet the distribution requirements and these sales may be subject to the risk factors discussed above. A Fund is not limited in the amount of its assets that may be invested in these types of securities.

Cybersecurity Risk

With the increased use of technologies such as the internet and the dependence on computer systems to perform necessary business functions, the Funds and their service providers may have become more susceptible to operational and related risks through breaches in cybersecurity. A cybersecurity incident may refer to intentional or unintentional events that allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause a Fund or Fund service providers (including, but not limited to, the Manager, distributor, fund accountants, custodian, transfer agent, and financial intermediaries) to suffer data corruption or lose operational functionality. A cybersecurity incident could, among other things, result in the loss or theft of customer data or funds, customers or employees being unable to access electronic systems (denial of services), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or remediation costs associated with system repairs.

Any of these results could have a substantial adverse impact on a Fund and its shareholders. For example, if a cybersecurity incident results in a denial of service, Fund shareholders could lose access to their electronic accounts and be unable to buy or sell Fund shares for an unknown period of time, and employees could be unable to access electronic systems to perform critical duties for the Fund, such as trading, NAV calculation, shareholder accounting or fulfillment of Fund share purchases and redemptions. Cybersecurity incidents could cause a Fund or Fund service provider to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures, or financial loss of a significant magnitude and could result in allegations that a Fund or Fund service provider violated privacy and other laws.

Similar adverse consequences could result from cybersecurity incidents affecting issuers of securities in which the Fund invests, counterparties with which a Fund engages in transactions, governmental and other regulatory authorities, exchange and other financial market operators, banks, brokers, dealers, insurance companies, and other financial institutions and other parties. Risk management systems and business continuity plans seek to reduce the risks associated with cybersecurity in the event there is a cybersecurity breach, but there are inherent limitations in these systems and plans, including the possibility that certain risks may not have been identified, in large part because different or unknown threats may emerge in the future. Furthermore, the Funds do not control the cybersecurity systems and plans of the issuers of securities in which the Funds invest or the Funds’ third party service providers or trading counterparties or any other service providers whose operations may affect the Funds or their shareholders.

As an open-end management investment company, the Trust has delegated its operational activities to third-party service providers, subject to the oversight of the Board. Because the Trust operates its business through third-party service providers, it does not itself have any operational or security systems or infrastructure that are potentially subject to cyber attacks. The third-party service providers that facilitate the Trust’s business activities, including, but not limited to, fund management, custody of Trust assets, fund accounting and financial administration, and transfer agent services, could be sources of operational and informational security risk to the Trust and its shareholders, including from breakdowns or failures of the third-party service providers’ own systems or capacity constraints. A failure or breach of the operational or security systems or infrastructure of the Trust’s third-party service providers could disrupt the Trust’s operations, result in the disclosure or misuse of confidential or proprietary information, and cause losses. Although the Trust and its third-party service providers have business continuity plans and other safeguards in place, the operations of the Trust’s third-party service providers may be adversely affected by significant disruption of the service providers’ operating systems or physical infrastructure that support the Trust and its shareholders.

The proliferation of new technologies, the use of the Internet and telecommunications technologies to conduct business, as well as the increased sophistication and activities of organized crime, hackers, terrorists, activists, and others, have significantly increased the information security risks to which the Trust’s third-party service providers are subject. The third-party service providers rely on digital technologies, computer and email systems, software, and networks to conduct their business and the business of the Trust. The Trust’s third-party service providers have robust information security procedures; however, their technologies may become the target of cyber attacks or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss, or destruction of the Trust’s or its shareholders’ confidential and other information, or otherwise disrupt the business operations of the Trust or its third-party service providers. Although to date the Trust has not experienced any material losses relating to cyber attacks or other information security breaches, there can be no assurance that the Trust or its third-party service providers will not suffer such losses in the future.

Disruptions or failures in the physical infrastructure or operating systems that support the Trust’s third-party service providers, or cyber attacks or security breaches of the networks, systems, or devices that the Trust’s third-party service providers use to service the Trust’s operations, could result in financial losses, the inability of Trust shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, and/or additional compliance costs. The business continuity policies and procedures that the Trust and its third-party service providers have established seek to identify and mitigate the types of risk to which the Trust and its third-party service providers are subject. As with any risk-management system, there are inherent limitations to these business continuity policies and procedures as there may exist, or develop in the future, risks that have not been anticipated or identified.

IBOR Transition Risk

The London Interbank Offered Rate (“LIBOR”) is the average offered rate for various maturities of short-term loans between major international banks who are members of the British Bankers Association (“BBA”). LIBOR was a common benchmark interest rate index used to make adjustments to variable-rate loans and was used throughout global banking and financial industries to determine interest rates for a variety of borrowing arrangements and financial instruments (such as debt instruments and derivatives). Regulators in the United States and the United Kingdom alleged that certain banks engaged in manipulative acts in connection with their submissions to the BBA. LIBOR manipulation would raise the risk of a fund of being adversely impacted if a fund received a payment based upon LIBOR and such manipulation of LIBOR resulted in lower resets than would have occurred had there been no manipulation.

In addition to LIBOR, a fund may have investments linked to other interbank offered rates (“IBORs”). Other IBORs, such as the Euro Overnight Index Average (EONIA), are also the subject of regulatory reform or discontinuation. Over the past several years, various regulators and industry bodies have worked together to identify alternative reference rates (“ARRs”) to replace LIBOR and assist with the transition to the new ARRs. The majority of LIBOR rates were phased out at the end of 2021. The most common tenors of USD LIBOR (overnight and 1-, 3-, 6- and 12- month) will cease publication as of June 30, 2023.

There remains uncertainty and risks related to converting certain longer-term securities and transactions to a new ARR. For example, there can be no assurance that the composition or characteristics of any ARRs or financial instruments in which a fund invests that utilize ARRs will be similar to or produce the same value or economic equivalence as LIBOR or that these instruments will have the same volume or liquidity. While some instruments tied to LIBOR or a similar rate may include a replacement rate in the event these rates are discontinued, not all instruments have such fallback provisions and the effectiveness of such replacement rates remains uncertain. The cessation of LIBOR or similar rates could affect the value and liquidity of investments tied to these rates, especially those that do not include fallback provisions. The effect of a transition away from the IBORs may also result in a reduction in the effectiveness of certain hedging transactions and increased volatility in markets that currently rely on an IBOR to determine interest rates. The use of alternative reference rate products may also impact investment strategy performance. Due to the uncertainty regarding the future utilization of LIBOR and similar rates and the nature of any replacement rate, the potential effect of a transition away from these rates on a fund or the financial instruments in which the fund invests cannot yet be determined.

Natural Disaster/Epidemic Risk

Natural or environmental disasters, such as earthquakes, fires, floods, hurricanes, tsunamis, and other severe weather-related phenomena generally, and widespread disease, including pandemics and epidemics, have been and can be highly disruptive to economies and markets, adversely impacting individual companies, sectors, industries, markets, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of a fund’s investments. Given the increasing interdependence among global economies and markets, conditions in one country, market, or region are increasingly likely to adversely affect markets, issuers, and/or foreign exchange rates in other countries. These disruptions could prevent a fund from executing advantageous investment decisions in a timely manner and could negatively impact the fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of a fund.

Disclosure of Portfolio Holdings Information

Each Fund has adopted a policy generally prohibiting the disclosure of portfolio holdings information to any person until after 30 calendar days have passed. The Trust posts a list of the Funds’ portfolio holdings monthly, with a 30-day lag, on the Funds’ website, optimummutualfunds.com. In addition, on a 10-day lag, we also make available on the website a month-end summary listing of the number of the Funds’ securities, country and asset allocations, and top 10 securities and sectors by percentage of holdings for each Fund. This information is available publicly to any and all shareholders free of charge once posted on the Funds' website, optimummutualfunds.com, or by calling 800 914-0278.

Other entities, including institutional investors and intermediaries that distribute the Funds’ shares, are generally treated similarly and are not provided with the Funds’ portfolio holdings in advance of when they are generally available to the public.

The Funds may, from time to time, provide statistical data derived from publicly available information to third parties, such as shareholders, prospective shareholders, financial intermediaries, consultants, and ratings and ranking organizations.

Third-party service providers and affiliated persons of the Funds are provided with the Funds’ portfolio holdings only to the extent necessary to perform services under agreements relating to the Funds. In accordance with the policy, third-party service providers who receive nonpublic portfolio holdings information on an ongoing basis are: the Manager’s affiliates (Macquarie Investment Management Business Trust, Delaware Investments Fund Services Company, and the Distributor), the Funds’ Sub-Advisors and their agents, the Funds’ independent registered public accounting firm, the Funds’ custodian, the Funds’ legal counsel, the Funds’ financial printer (DG3), and the Funds’ proxy voting service. These entities are obligated to keep such information confidential.

Third-party rating and ranking organizations and consultants who have signed agreements (“Nondisclosure Agreements”) with the Funds or the Manager may receive portfolio holdings information more quickly than the 30-day lag. The Nondisclosure Agreements require that the receiving entity hold the information in the strictest confidence and prohibit the receiving entity from disclosing the information or trading on the information (either in Fund shares or in

shares of the Funds’ portfolio securities). In addition, the receiving party must agree to provide copies of any research or reports generated using the portfolio holdings information in order to allow for monitoring of use of the information. Neither the Funds, nor the Manager, nor any affiliate, receives any compensation or consideration with respect to these agreements.

To protect the shareholders’ interests and to avoid conflicts of interest, Nondisclosure Agreements must be approved by a member of the Manager’s Legal Department and Compliance Department and any deviation in the use of the portfolio holdings information by the receiving party must be approved in writing by the Funds’ Chief Compliance Officer prior to such use.

The Board will be notified of any substantial changes to the foregoing procedures. The Board also receives an annual report from the Trust’s Chief Compliance Officer that, among other things, addresses the operation of the Trust’s procedures concerning the disclosure of portfolio holdings information.

Management of the Trust

Trustees and officers

The business and affairs of the Trust are managed under the direction of its Board. Certain officers and Trustees of the Trust hold identical positions in each of the funds in the Delaware Funds. The Trust’s Trustees and principal officers are noted below along with their birthdates and their business experience for the past five years. The Trustees serve for indefinite terms until their resignation, death, or removal.

As of January 13, 2023, the officers and Trustees of the Trust directly owned less than 1% of the outstanding shares of each Class of each Fund.

The following table shows each Trustee’s ownership of shares of each Fund and of the Optimum Funds complex in the aggregate as of December 31, 2021.

The following table describes the aggregate compensation received by each Trustee from the Trust entitled to receive compensation for the Trust’s last fiscal year. Only the Trustees of the Trust who are not “interested persons” as defined by the 1940 Act (the “Independent Trustees”) receive compensation from the Trust.

Board Leadership Structure

Board Chair: Ms. Moret, an Independent Trustee, serves as Chair of the Board. The Chair, in consultation with Fund management, counsel and the other Trustees, proposes Board agenda topics, actively participates in developing Board meeting agendas, and ensures that appropriate and timely information is provided to the Board in connection with Board meetings. The Chair also conducts meetings of the Board. The Chair also generally serves as a liaison between outside Trustees, Fund officers and counsel.

Size and composition of Board: The Board is currently comprised of 11 Trustees. The Trustees believe that the current size of the Board is conducive to Board interaction, dialogue and debate, resulting in an effective decision-making body. The Board is comprised of Trustees with a variety of professional backgrounds. The Board believes that the skill sets of its members are complementary and add to the overall effectiveness of the Board. The Trustees regard diversity as an important consideration in the present composition of the Board and the selection of qualified candidates to fill vacancies on the Board. In order to ensure that Board membership will be refreshed from time to time, the Board has adopted a mandatory retirement age of 75 for Trustees. As a result, a Trustee may serve until December 31 of the calendar year in which such Trustee reaches the age of 75. At the discretion of the other Trustees, active service for a particular Trustee may be extended for a limited period of time beyond a Trustee’s normal retirement date.

Committees: The Board has established committees, each of which focuses on a particular substantive area and provides reports and recommendations to the full Board. The committee structure enables the Board to manage efficiently and effectively the large volume of information relevant to the Board’s oversight of the Funds. The committees benefit from the professional expertise of their members. At the same time, membership on a committee enhances the expertise of its members and benefits the overall effectiveness of the Board.

The Board has the following committees:

Audit Committee: This Committee monitors accounting and financial reporting policies and practices, and internal controls for the Trust. It also oversees the quality and objectivity of the Trust's financial statements and the independent audit thereof, and acts as a liaison between the Trust's independent registered public accounting firm and the full Board. The Trust's Audit Committee consists of the following six Independent Trustees: Susan M. Stalnecker, Chair; Robert J. Christian; Mark K. Hancock; Pamela J. Moret; Robert A. Rudell and Edward Ramos. The Audit Committee held five meetings during the Trust's last fiscal year.

Nominating and Governance Committee: The Committee conducts a variety of activities, including but not limited to: reviewing the Funds' Chief Compliance Officer compensation; overseeing the Board's annual self-assessment; reviewing and recommending any changes to Trustee compensation; and reviewing the performance of the Independent Trustees' counsel. The Nominating and Governance Committee also recommends Board members for vacancies and considers the qualifications of Board members. In reaching its determination that an individual should serve or continue to serve as a Trustee of the Trust, the committee considers, in light of the Trust's business and structure, the individual's experience, qualifications, attributes and skills (the “Selection Factors”). No one Selection Factor is determinative, but some of the relevant factors that have been considered include: (i) the Trustee's business and professional experience and accomplishments, including prior experience in the financial services industry or on other boards; (ii) the ability to work effectively and collegially with other people; and (iii) how the Trustee's background and attributes contribute to the overall mix of skills and experience on the Board as a whole. Information on the business activities of the Trustees during the past five years appears in this SAI, and it is believed that the specific

background of each Trustee demonstrates that each Trustee has appropriate Selection Factors to evidence the Trustee's ability to serve on the Board. In particular, Messrs. Pettman, Christian, Rudell, Chavers, Ramos, and Hancock and Ms. Moret and Gonzales-Burdin have each held senior management positions at major financial services firms, and each of these individuals has had experience dealing with mutual funds and / or asset managers prior to becoming Trustees. Mr. Mullin is an economist who teaches at Drexel University, and he is currently a principal in an economic consulting firm. He also was previously the Finance Director for the City of Philadelphia. Mr. Hunter was an executive recruiter and was a partner in an executive search and board services firm. He focused on investment management. Ms. Stalnecker was employed by E.I. du Pont de Nemours & Co., serving in numerous senior roles during her tenure, including Vice President and Treasurer, and most recently as Vice President of Corporate Productivity and Hospitality. She also is currently a Trustee for the Duke Health System, and she serves on the Board of Directors of Leidos and Bioventus. The Nominating and Governance Committee consists of the following four Independent Trustees: Kevin G. Chavers, Chair, Dianna Gonzales-Burdin, Durant A. Hunter, and Stephen P. Mullin. The Nominating and Governance Committee held four meetings during the last fiscal year.

Board role in risk oversight: The Board performs a risk oversight function for the Trust consisting, among other things, of the following activities: (1) receiving and reviewing reports related to the performance and operations of the Funds of the Trust; (2) reviewing, approving, or modifying as applicable, the compliance policies and procedures of the Trust; (3) meeting with portfolio management teams to discuss portfolio performance, including investment risk; (4) addressing security valuation risk in connection with its review of fair valuation decisions made by Fund management pursuant to Board-approved procedures; (5) meeting with representatives of key service providers, including the Manager, the Sub-Advisors, the Distributor, the Transfer Agent, the custodian and the independent public accounting firm of the Trust, to review and discuss the activities of the Funds of the Trust and to provide direction with respect thereto; and (6) engaging the services of the Chief Compliance Officer of the Funds of the Trust to test the compliance procedures of the Trust and its service providers. The Trustees perform this risk oversight function throughout the year in connection with each quarterly Board meeting. In addition, the Audit Committee reviews valuation procedures and results with the Funds' auditors in connection with such Committee's review of the results of the audit or each Fund's year-end financial statements, and meets with the Manager's internal audit and risk-management personnel on a quarterly basis to review the reports on their examinations of functions and processes affecting the Funds.

Because risk is inherent in the operation of any business endeavor, and particularly in connection with the making of financial investments, there can be no assurance that the Board's approach to risk oversight will be able to minimize or even mitigate any particular risk. Each Fund is designed for investors that are prepared to accept investment risk, including the possibility that as yet unforeseen risks may emerge in the future.

Code of Ethics

The Trust, the Manager , the sub-advisors and the Distributor have adopted Codes of Ethics in compliance with the requirements of Rule 17j-1 under the 1940 Act, which govern personal securities transactions. Under the Codes of Ethics, persons subject to the Codes are permitted to engage in personal securities transactions, including securities that may be purchased or held by the Funds, subject to the requirements set forth in Rule 17j-1 under the 1940 Act and certain other procedures set forth in the applicable Code of Ethics. The Codes of Ethics are on public file with, and are available from, the SEC.

Proxy Voting Policies — The Manager

The Trust has delegated to the Manager the responsibility for making all proxy voting decisions in relation to the portfolio securities held by the Funds. The Manager has, in turn, delegated to each Sub-advisor the responsibility to vote proxies with respect to portfolio securities held by the portion of a Fund that such Sub-advisor advises. The Manager has retained the responsibility to vote proxies with respect to portfolio securities held by the Funds (or portions thereof) that it advises directly. The Manager and each Sub-advisor have adopted policies and procedures with respect to voting proxies relating to securities held in client accounts for which they have discretionary authority. It is possible that one Sub-advisor on a given Fund may vote differently than another Sub-advisor on the same Fund in regards to the same proxy issue based on that Sub-advisor’s proxy voting policies and procedures. Copies of the policies and procedures for the Manager and each Sub-advisor are included with this SAI. See “Appendix B — Proxy Voting Policies and Procedures.” Information, if any, regarding how the Funds voted proxies relating to their respective portfolio securities during the most recent 12-month period ended June 30 is available without charge: (i) through the Funds’ website at optimummutualfunds.com; and (ii) on the SEC’s website at sec.gov.

Investment Manager and Other Service Providers

Investment Manager

The Manager, located at 100 Independence, 610 Market Street, Philadelphia, PA 19106-2354, furnishes investment management services to the Funds, subject to the supervision and direction of the Board. The Manager also provides investment management services to all of the other Delaware Funds. Affiliates of the Manager also manage other investment accounts. While investment decisions for the Funds are made independently from those of the other funds and accounts, investment decisions for such other funds and accounts may be made at the same time as investment decisions for the Funds. The Manager is registered under the Investment Advisers Act of 1940, as amended (the “Advisers Act”). The Manager pays the salaries of all Trustees, officers, and employees who are affiliated with both the Manager and the Trust. In the course of discharging its non-portfolio management duties under the advisory contract, the Manager may delegate to affiliates.

Together, the Manager and the subsidiaries of Macquarie Management Holdings, Inc. (“MMHI”) manage, as of September 30, 2022, approximately $192.2 billion in assets, including mutual funds, separate accounts, and other investment vehicles. The Manager is a series of Macquarie Investment Management Business Trust (a Delaware statutory trust), which is a subsidiary of MMHI. MMHI is a subsidiary, and subject to the ultimate control, of Macquarie Group Limited (“Macquarie”). Macquarie is a Sydney, Australia-headquartered global provider of banking, financial, advisory, investment and funds management services. “Macquarie Investment Management” is the marketing name for MMHI and its subsidiaries.

MMHI has consented to, and granted a non-exclusive license for, the use by any Fund or by the Trust of the identifying word “Optimum” in the name of any Fund or of the Trust. Such consent is subject to revocation by MMHI in its discretion, if MMHI or a subsidiary or affiliate thereof is not employed as the investment adviser of each Fund of the Trust. As between the Trust and MMHI, MMHI controls the use of the name of the Trust insofar as such name contains the identifying word “Optimum.” MMHI may, from time to time, use the identifying word “Optimum” in other connections and for other purposes, including, without limitation, in the names of other investment companies, corporations or businesses that it may manage, advise, sponsor or own or in which it may have a financial interest. MMHI may require the Trust or any Fund thereof to cease using the identifying word “Optimum” in the name of the Trust or any Fund thereof if the Trust or any Fund thereof ceases to employ MMHI or a subsidiary or affiliate thereof as investment adviser.

The Investment Management Agreement (the “Agreement”) for the Funds is dated January 4, 2010 and was approved by shareholders on November 12, 2009. Under the Agreement, the Manager has full discretion and responsibility, subject to the overall supervision of the Trust’s Board, to select and contract with one or more investment sub-advisors (“Sub-advisors”), to manage the investment operations and composition of each Fund, and to render investment advice for each Fund, including the purchase, retention, and disposition of investments, securities and cash contained in each Fund. The Agreement obligates the Manager to implement decisions with respect to the allocation or reallocation of each Fund’s assets among one or more current or additional Sub-advisors, and to monitor the Sub-advisors’ compliance with the relevant Fund’s investment objective, policies and restrictions. Under the Agreement, the Trust will bear the expenses of conducting its business. The Trust and the Manager may share facilities in common to each, which may include legal and accounting personnel, with appropriate pro ration of expenses between them. In addition, the Manager pays the salaries of all officers and Trustees of the Trust who are officers, directors or employees of the Manager or its affiliates.

The Agreement had an initial term of two years and may be renewed each year only so long as such renewal and continuance are specifically approved at least annually by the Board or by vote of a majority of the outstanding voting securities of each Fund, and only if the terms of and the renewal thereof have been approved by the vote of a majority of the Independent Trustees of the Trust who are not parties thereto or interested persons of any such party, cast in person at a meeting called for the purpose of voting on such approval. The Agreement is terminable without penalty on 60 days’ notice by the Board or by the Manager. The Agreement will terminate automatically in the event of its assignment.

As compensation for services rendered under the Agreement, the Manager is entitled to receive an annual fee equal to the following percentage rates of the average daily net assets of each Fund:

During the last three fiscal years, the Funds paid the following investment management fees to the Manager:

Each Fund’s management fee, as a percentage of net assets, declines as assets increase above designated levels.

Except for those expenses borne by the Manager under the Agreement and the Distributor under the Distribution Agreement, each Fund is responsible for all of its own expenses. Among others, such expenses include the Funds’ proportionate share of certain administrative expenses; investment management fees; transfer agent and dividend disbursing fees and costs; accounting services; custodian expenses; federal and state securities registration fees; proxy costs; and the costs of preparing prospectuses and reports sent to shareholders.

The Manager has also entered into a Consulting Services Agreement with LPL to provide research to assist the Manager in evaluating and monitoring the Funds' performance and the Funds' Sub-advisors and in making recommendations to the Trustees about hiring and changing Sub-advisors. As compensation for services rendered to the Manager under the Consulting Services Agreement, LPL is entitled to receive an annual fee equal to the following percentage rates of the average daily net assets of the Trust. The Manager is responsible for paying LPL the following consulting fee out of the Manager's assets:

Sub-Advisors

The Manager has entered into Sub-Advisory Agreements on behalf of each Fund. The Sub-Advisory Agreements obligate American Century Investment Management, Inc.

During the Funds' last fiscal year, the Manager did not pay compensation to the Affiliated Sub-Advisors for services rendered under the Sub-Advisory Agreements.

Distributor

The Distributor, Delaware Distributors, L.P., located at 100 Independence, 610 Market Street, Philadelphia, PA 19106-2354, serves as the national distributor of the Fund’s shares under a Distribution Agreement dated May 15, 2003, as amended and restated January 4, 2010, and further amended and restated on February 25, 2016. The Distributor is an affiliate of the Manager and bears all of the costs of promotion and distribution, except for payments by the Retail Classes under their respective Rule 12b-1 Plans. The Distributor is an indirect subsidiary of MMHI and, therefore, of Macquarie. The Distributor has agreed to use its best efforts to sell shares of the Funds. See the Prospectus for information on how to invest. Shares of the Funds are offered on a continuous basis by the Distributor and may be purchased through authorized investment dealers or directly by contacting the Distributor or the Trust. The Distributor also serves as the national distributor for the Delaware Funds. The Board annually reviews fees paid to the Distributor.

During the Funds’ past three fiscal years, the Distributor received net commissions from each Fund on behalf of its Class A shares, after re-allowances to dealers, as follows:

B. Description of Material Conflicts of Interest

Optimum Large Cap Growth Fund

American Century
Certain conflicts of interest may arise in connection with the management of multiple portfolios. Potential conflicts include, for example, conflicts among investment strategies, such as one portfolio buying or selling a security while another portfolio has a differing, potentially opposite position in such security. This may include one portfolio taking a short position in the security of an issuer that is held long in another portfolio (or vice versa). Other potential conflicts may arise with respect to the allocation of investment opportunities, which are discussed in more detail below. American Century has adopted policies and procedures that are designed to minimize the effects of these conflicts.

Responsibility for managing American Century client portfolios is organized according to investment discipline. Investment disciplines include, for example, disciplined equity, global growth equity, global value equity, global fixed income multi-asset strategies, exchange traded funds, and Avantis Investors funds. Within each discipline are one or more portfolio teams responsible for managing specific client portfolios. Generally, client portfolios with similar strategies are managed by the same team using the same objective, approach, and philosophy. Accordingly, portfolio holdings, position sizes, and industry and sector exposures tend to be similar across similar portfolios, which minimizes the potential for conflicts of interest. In addition, American Century maintains an ethical wall around each of its equity investment disciplines (global growth equity, global value equity, disciplined equity, equity exchange traded funds, and Avantis Investors funds), meaning that access to information regarding any portfolio’s transactional activities is only available to team members of the investment discipline that manages such portfolio.

The ethical wall is intended to aid in preventing the misuse of portfolio holdings information and trading activity in the other disciplines.

For each investment strategy, one portfolio is generally designated as the “policy portfolio.” Other portfolios with similar investment objectives, guidelines and restrictions, if any, are referred to as “tracking portfolios.” When managing policy and tracking portfolios, a portfolio team typically purchases and sells securities across all portfolios that the team manages. American Century’s trading systems include various order entry programs that assist in the management of multiple portfolios, such as the ability to purchase or sell the same relative amount of one security across several funds. In some cases a tracking portfolio may have additional restrictions or limitations that cause it to be managed separately from the policy portfolio. Portfolio managers make purchase and sale decisions for such portfolios alongside the policy portfolio to the extent the overlap is appropriate, and separately, if the overlap is not.

American Century may aggregate orders to purchase or sell the same security for multiple portfolios when it believes such aggregation is consistent with its duty to seek best execution on behalf of its clients. Orders of certain client portfolios may, by investment restriction or otherwise, be determined not available for aggregation. American Century has adopted policies and procedures to minimize the risk that a client portfolio could be systematically advantaged or disadvantaged in connection with the aggregation of orders. To the extent equity trades are aggregated, shares purchased or sold are generally allocated to the participating portfolios pro rata based on order size. Because initial public offerings (IPOs) are usually available in limited supply and in amounts too small to permit across-the-board pro rata allocations, American Century has adopted special procedures designed to promote a fair and equitable allocation of IPO securities among clients over time. A centralized trading desk executes all fixed income securities transactions for Avantis ETFs and mutual funds. For all other funds in the American Century complex, portfolio teams are responsible for executing fixed income trades with broker/dealers in a predominantly dealer marketplace. Trade allocation decisions are made by the portfolio manager at the time of trade execution and orders entered on the fixed income order management system. There is an ethical wall between the Avantis trading desk and all other American Century traders. The Advisor’s Global Head of Trading monitors all trading activity for best execution and to make sure no set of clients is being systematically disadvantaged.

Finally, investment of American Century’s corporate assets in proprietary accounts may raise additional conflicts of interest. To mitigate these potential conflicts of interest, American Century has adopted policies and procedures intended to provide that trading in proprietary accounts is performed in a manner that does not give improper advantage to American Century to the detriment of client portfolios.

Los Angeles Capital
The potential for conflicts of interest arises when portfolio managers are responsible for multiple accounts including the Fund. Los Angeles Capital’s client accounts are managed independently of one another in accordance with client specific mandates, restrictions, and instructions. Los Angeles Capital has implemented policies and procedures, including brokerage and trade allocation policies and procedures, that Los Angeles Capital believes are reasonably designed to address the potential for conflicts of interest associated with managing portfolios for multiple clients and that seek to treat all clients fairly and equally over time.

Side-by-side management can result in investment positions or actions taken for one client account that differ from those taken in another client account. For example, one client account can engage in short sales of or take a short position in an investment that at the same time is owned or being purchased long in another client account. It is also possible that Los Angeles Capital may be purchasing or holding a security for one account and simultaneously selling the same security for another account. These positions and actions can adversely affect or benefit different clients at different times.

Los Angeles Capital may, at any given time, purchase and/or sell the same security in a block that is allocated among multiple accounts. The decision as to which accounts participate in an investment opportunity will take into account, among other things, the quantitative model’s outlook on the account’s strategy, the account’s investment guidelines, and the account’s risk metrics. Los Angeles Capital allocates trades that are submitted in a block prior to placing the trade with the broker. When there is decision making on whether to include or exclude certain accounts from a block transaction, there is always the potential for conflicts of interest. The effect of trade aggregation may work on some occasions to the account’s disadvantage. Los Angeles Capital’s

policies and procedures in allocating trades are structured to treat all clients fairly. Los Angeles Capital is not required to aggregate any particular trade. Los Angeles Capital’s proprietary optimization-based technology for trading client portfolios uses real-time market prices to parse the master (“parent”) order lists into a sub-list or “child” order lists, for execution by agency brokers. For accounts traded using the firm’s trade optimization technology, real- time market prices are the primary creation determinant in each child order. Therefore, names traded for one account (or group of accounts) may result in different execution prices than a name traded for another account (or group of accounts).

While Los Angeles Capital reserves the right to update its trading strategy, Los Angeles Capital generally alternates in trading its U.S. strategy accounts followed by its non-U.S. strategy accounts. An account’s rebalance cycle is dependent on the account’s strategy. Los Angeles Capital has designed a proprietary Brokerage Allocation Randomization system for objectively pairing which broker to use when executing an account’s transactions based on regional market eligibility/suitability characteristics, as well as perceived execution capability of the broker in such regional markets. Rebalances for U.S. strategy accounts are regularly rotated between traders and generally begin on the same day each week. The firm’s proprietary accounts, which are invested in liquid, benchmark securities, may be traded in rotation with client accounts or on a particular day of the week depending on liquidity, size, model constraints, and resource constraints. The order of account rebalances may work on some occasions to the account’s advantage or disadvantage.

Los Angeles Capital’s portfolio managers manage accounts that are charged a performance-based fee alongside accounts in the same strategy with asset-based fee schedules. While performance-based fee arrangements may be viewed as creating an incentive to favor certain accounts over others in the allocation of investment opportunities, Los Angeles Capital has designed and implemented procedures to ensure that all clients are treated fairly and equally, and to prevent conflicts from influencing the allocation of investment opportunities. Management and performance fees inure to the benefit of the firm as a whole and not to specific individuals or groups of individuals

Personal trading by Los Angeles Capital employees can present conflicts of interest. Los Angeles Capital has adopted a Code of Ethics that includes procedures on ethical conduct and personal trading including requirements for pre-clearance authorization from both the Trading and Compliance and Regulatory Risk Departments for certain security transactions. Nonetheless, because the Code of Ethics in some circumstances would permit an employee to invest in the same securities as clients, there is a possibility that such employee might benefit from market activity by a client in the same security.

Investment personnel of Los Angeles Capital or its affiliate may be permitted to be commercially or professionally involved with an issuer of securities. There is a potential risk that Los Angeles Capital personnel may place their own interests (resulting from outside employment/directorships) ahead of the interests of Los Angeles Capital clients. Before engaging in any outside business activity, employees must obtain approval of the CCO as well as other personnel. Any potential conflicts of interest from such involvement are monitored for compliance with Los Angeles Capital’s Code of Ethics. The Code of Ethics also governs employees giving or accepting gifts and entertainment.

Rothschild & Co
Rothschild & Co seeks to identify and monitor potential conflicts of interest and has adopted policies and procedures designed to address such potential conflicts. Investment teams and individual portfolio managers may manage multiple accounts, including separate accounts, commingled funds, and wrap accounts, using the same or a similar investment strategy (i.e., side-by-side management). The simultaneous management of these different investment products could create certain conflicts of interest as the fees for the management of certain types of products are higher than others.

The portfolio managers also manage accounts in which Rothschild & Co and/or its personnel have an interest. Rothschild & Co has an affirmative duty to treat all accounts fairly and equitably over time and maintains policies and has implemented policies and procedures designed to comply with that duty.

Although Rothschild & Co manages numerous accounts with similar or identical investment objectives, or may manage accounts with different objectives that trade in the same securities, the investment decisions relating to these accounts, and the performance resulting from such decisions, may differ from account to account. For example, different client guidelines and restrictions may result in different investment decisions between accounts. In addition, the portfolio managers will not necessarily purchase or sell the same securities at the same time or in the same proportionate amounts for all eligible accounts if certain accounts have materially different amounts of investable cash or liquidity needs.

Other factors that may result in different investment decisions include client-directed brokerage arrangements, soft dollar restrictions, and the sponsor-mandated execution of trades through specified broker-dealers in connection with certain wrap programs, all of which limit Rothschild & Co's brokerage discretion. Rothschild & Co seeks to identify and monitor potential conflicts of interest and has adopted policies and procedures designed to address such potential conflicts.

MFS
MFS seeks to identify potential conflicts of interest resulting from a portfolio manager’s management of both the Fund and other accounts, and has adopted policies and procedures designed to address such potential conflicts. There is no guarantee that MFS will be successful in identifying or mitigating conflicts of interest.

The management of multiple funds and accounts (including accounts in which MFS or an affiliate has an interest) gives rise to conflicts of interest if the funds and accounts have different objectives and strategies, benchmarks, time horizons, and fees, as a portfolio manager must allocate his or her time and investment ideas across multiple funds and accounts. In certain instances, there are securities which are suitable for the Fund’s portfolio as well as for one or more other accounts advised by MFS or its subsidiaries (including accounts in which MFS or an affiliate has an interest) with similar investment objectives.

MFS' trade allocation policies could have a detrimental effect on the Fund if the Fund’s orders do not get fully executed or are delayed in getting executed due to being aggregated with those of other accounts advised by MFS or its subsidiaries. A portfolio manager may execute transactions for another fund or account that may adversely affect the value of the Fund’s investments. Investments selected for funds or accounts other than the Fund may outperform investments selected for the Fund. 

When two or more accounts are simultaneously engaged in the purchase or sale of the same security, the securities are allocated among clients in a manner believed by MFS to be fair and equitable to each over time. Allocations may be based on many factors and may not always be pro rata based on assets managed. The allocation methodology could have a detrimental effect on the price or availability of a security with respect to the Fund.

MFS and/or a portfolio manager may have a financial incentive to allocate favorable or limited opportunity investments or structure the timing of investments to favor accounts other than the Fund; for instance, those that pay a higher advisory fee and/or have a performance adjustment, those that include an investment by the portfolio manager, and/or those in which MFS, its officers and/or employees, and/or its affiliates own or have an interest.

To the extent permitted by applicable law, certain accounts may invest their assets in other accounts advised by MFS or its affiliates, including accounts that are advised by one or more of the same portfolio manager(s), which could result in conflicts of interest relating to asset allocation, timing of purchases and redemptions, and increased profitability for MFS, its affiliates, and/or its personnel, including portfolio managers.

CCI
PDG continuously and annually reviews new and existing business arrangements for key conflicts of interest. PDG’s Compliance Team attends timely training on compliance issues and works closely with PDG's third-party compliance consultant to maintain and update PDG's Compliance Program. PDG's Form ADV Part 2A provides disclosure of key conflicts of interest and describes certain procedures to mitigate or eliminate conflicts.

As of 12/31/2017, PDG no longer operates any Private Funds. PDG’s sub-advised strategies may make investments in the same securities as other PDG sub-advised strategies if such funds/securities overlap. PDG seeks to allocate investment opportunities in a manner which it believes to be fair and equitable across any participating accounts. With respect to allocation of investment opportunities, the Portfolio Managers choose whether to make investments within their respective portfolios. The Portfolio Managers have open access to each other's investments and can review opportunities accordingly. PDG does not permit cross trades.

PDG has a comprehensive set of policies and procedures pursuant to 206(4)-7 under the Investment Advisers Act of 1940, including certain policies and procedures are specifically directed to managing conflicts of interest.

Peregrine
All Peregrine Small Cap Growth portfolios with comparable objectives and constraints are managed alike. Portfolio trades are allocated on a pro rata basis across all client accounts. This holds true for both existing public companies and IPO allocations.

All transactions are allocated on or prior to entry of an order (new issues should be allocated on the day of the underwriter’s allotment and before trading commences whenever feasible) with the ongoing objective of fair and equitable treatment of all accounts.

Exceptions to a pro rata allocation may be based on the following factors: (1) the market capitalization of the security involved, (2) the number of shares transacted, (3) the account’s current cash position and near-term cash requirements, (4) cash flows, (5) the relative size of a security position versus target, (6) industry/sector weightings, (7) client and style constraints, (8) de minimis standards and (9) other factors which the portfolio manager determines would be fair and equitable for all accounts in a particular management style.

Because Peregrine is likely to receive a limited share allotment on initial public offerings, a pro rata allocation to all accounts managed in a particular style may not be practical in some situations. Peregrine may rotate participation in public offerings among all accounts managed in that style in an attempt to achieve fair and equitable treatment.

Trades generally are allocated using the average share price of all the transactions in a security occurring on the same day. Exceptions result when separate trades in the same security are initiated at a different time or if trades are executed by more than one broker. Examples: (a) a trade with a client-directed broker and an aggregated (block) trade with another broker, and (b) a new issue security purchased on the deal and in the aftermarket.

Partially filled trades will be allocated on a pro rata basis subject to de minimis standards. De Minimis Standards ‑ Allocations may be revised or re-allocated to reflect a specified minimum number of shares and/or a specified minimum portfolio position of less than a specified percentage of total market value.

Optimum Small-Mid Cap Value Fund

LSV
The same team of portfolio managers is responsible for the day-to-day management of all of LSV’s accounts. LSV uses a proprietary quantitative investment model to manage all of LSV’s accounts. LSV relies extensively on its quantitative investment model regarding the advisability of investing in a particular company. Any investment decisions are generally made based on whether a buy or sell signal is received from the proprietary quantitative investment model. Accounts or funds with performance-based fees and accounts or funds in which employees may be invested could create an incentive to favor those accounts or funds over other accounts or funds in the allocation of investment opportunities. In addition, it is possible that a short position may be taken on a

security that is held long in another portfolio. LSV seeks to make allocations of investment opportunities in a manner that it considers fair, reasonable and equitable without favoring or disfavoring, consistently or consciously, any particular client. LSV has procedures designed to ensure that all clients are treated fairly and to prevent these potential conflicts from influencing the allocation of investment opportunities among clients. On a quarterly basis, the Forensic Testing Committee, consisting of the Chief Compliance Officer, Compliance Officer, Chief Operating Officer and Compliance Analyst, reviews, among other things, allocations of investment opportunities among clients and the allocation of partially-filled block, including allocations to accounts or funds with performance-based fees or in which employees may be invested, trades to confirm consistency with LSV’s policies and procedures.

Cardinal Capital Management, L.L.C.
Cardinal has adopted and implemented policies and procedures intended to address conflicts of interest relating to the management of multiple accounts, including accounts with multiple fee arrangements, and the allocation of investment opportunities. Cardinal and its investment personnel manage both client accounts that are charged performance-based compensation and accounts that are charged an asset-based fee, which is a non-performance-based fee. In addition, certain client accounts may have higher asset-based fees than other accounts. When Cardinal and its investment personnel manage more than one client account a potential exists for one client account to be favored over another client account. Cardinal and its investment personnel may have a greater incentive to favor client accounts that pay Cardinal (and indirectly the portfolio manager) performance-based compensation or higher fees. Cardinal reviews investment decisions for the purpose of ensuring that all accounts with substantially similar investment objectives are treated equitably. The performance of similarly managed accounts is also regularly compared to determine whether there are any unexplained significant discrepancies. In addition, Cardinal’s procedures relating to the allocation of investment opportunities require that similarly managed accounts participate in investment opportunities pro rata based on asset size and require that, to the extent orders are aggregated, the client orders are price-averaged. Finally, Cardinal’s procedures also require the objective allocation for limited opportunities (such as initial public offerings) to ensure fair and equitable allocation among accounts. These areas are monitored by Cardinal’s chief compliance officer.

Optimum International Fund

Baillie Gifford Overseas Limited
Baillie Gifford has a duty to act in the best interests of its clients and to treat them fairly when providing investment services. From time to time, there may be situations that give rise to a conflict of interest. A conflict can arise between the interests of Baillie Gifford, its partners and employees, and the interests of a client of Baillie Gifford. A conflict of interest can also arise between the interests of one client of Baillie Gifford and another client. In such circumstances we have put in place effective organizational and administrative arrangements to ensure that reasonable steps are taken to prevent the conflict giving rise to a material risk of damage to the interests of our clients. In addition, where we pay or accept any fee or commission, or provide or receive any non-monetary benefit in relation to our investment services, we take care to ensure that such benefits do not place Baillie Gifford or any third party firm in a situation which would not be in compliance with the general duty to act in accordance with the best interests of our clients.

Baillie Gifford maintains a firm-wide Conflicts Policy and Matrix which identifies conflicts and potential conflicts of interest that exist within the firm, and the procedures and controls that have been adopted to manage these conflicts. It is maintained by the Chief Compliance Officer and is subject to review and approval by the Compliance Committee which consists of a cross section of senior management.

Acadian
A conflict of interest may arise as a result of a portfolio manager being responsible for multiple accounts, including the subject Fund, which may have different investment guidelines and objectives. In addition to the subject Fund, these accounts may include other mutual funds managed on an advisory or sub-advisory basis, separate accounts and collective trust accounts. An investment opportunity may be suitable for the subject Fund as well as for any of the other managed accounts. However, the investment may not be available in sufficient quantity for all of the accounts to participate fully. In addition, there may be limited opportunity to sell an investment held by the subject Fund and the Other Accounts. The Other Accounts may have similar investment objectives or strategies as the subject Fund, may track the same benchmarks or indexes as the subject Fund tracks, and may sell securities that are eligible to be held, sold or purchased by the subject Fund. A portfolio manager may be responsible for accounts that have different advisory fee schedules, which may create the incentive for the portfolio manager to favor one account over another in terms of access to investment opportunities. A portfolio manager may also manage accounts whose investment objectives and policies differ from those of the subject Fund, which may cause the portfolio manager to effect trading in one account that may have an adverse effect on the value of the holdings within another account, including the subject Fund.

To address and manage these potential conflicts of interest, Acadian has adopted compliance policies and procedures to allocate investment opportunities and to ensure that each of its clients is treated on a fair and equitable basis. Such policies and procedures include, but are not limited to, trade allocation and trade aggregation policies, portfolio manager assignment practices and oversight by investment management and the Compliance team.

Optimum Fixed Income Fund

The Manager
Individual portfolio managers may perform investment management services for other funds or accounts similar to those provided to the Fund and the investment action for each such other fund or account and the Funds may differ. For example, an account or fund may be selling a security, while another account or fund may be purchasing or holding the same security. As a result, transactions executed for one fund or account may adversely affect the value of securities held by another fund, account, or the Funds. Additionally, the management of multiple other funds or accounts may give rise to potential conflicts of interest, as a portfolio manager must allocate time and effort to multiple funds or accounts and the Funds. A portfolio manager may discover an investment

opportunity that may be suitable for more than one account or fund. The investment opportunity may be limited, however, so that all funds or accounts for which the investment would be suitable may not be able to participate. The Manager has adopted procedures designed to allocate investments fairly across multiple funds and accounts.

One of the accounts managed by the portfolio managers as set forth in the table above has performance-based fees. This compensation structure presents a potential conflict of interest because the portfolio managers have an incentive to manage this account so as to enhance performance, to the possible detriment of other accounts for which the Manager does not receive a performance-based fee. A portfolio manager’s management of personal accounts also may present certain conflicts of interest. While the Manager’s code of ethics is designed to address these potential conflicts, there is no guarantee that it will do so.

PIMCO
From time to time, potential and actual conflicts of interest may arise between a portfolio manager’s management of the investments of a Fund, on the one hand, and the management of other accounts, on the other. Potential and actual conflicts of interest may also arise as a result of PIMCO’s other business activities and PIMCO’s possession of material non-public information (“MNPI”) about an issuer. Other accounts managed by a portfolio manager might have similar investment objectives or strategies as the Funds, track the same index a Fund tracks or otherwise hold, purchase, or sell securities that are eligible to be held, purchased or sold by the Funds. The other accounts might also have different investment objectives or strategies than the Funds. Potential and actual conflicts of interest may also arise as a result of PIMCO serving as investment adviser to accounts that invest in the Funds. In this case, such conflicts of interest could in theory give rise to incentives for PIMCO to, among other things, vote proxies or redeem shares of a Fund in a manner beneficial to the investing account but detrimental to the Fund. Conversely, PIMCO’s duties to the Funds, as well as regulatory or other limitations applicable to the Funds, may affect the courses of action available to PIMCO-advised accounts (including certain Funds) that invest in the Funds in a manner that is detrimental to such investing accounts.
