GENERAL INFORMATION

The Portfolio is a diversified series of Nuveen Managed Accounts Portfolios Trust (the “Trust”), an open-end management investment company organized as a Massachusetts business trust on November 14, 2006. The Trust is a series company under Rule 18f-2 of the Investment Company Act of 1940, as amended (the “1940 Act”). The Trust currently has two series. As a series of the Trust, the Portfolio represents shares of beneficial interest in a separate portfolio of securities and other assets, with its own objectives and policies. The Portfolio was developed exclusively for use within Nuveen-sponsored separately managed accounts. The Portfolio’s investment adviser is Nuveen Fund Advisors, LLC (“Nuveen Fund Advisors” or the “Adviser”). The Portfolio’s sub-adviser is Nuveen Asset Management, LLC (“Nuveen Asset Management” or the “Sub-Adviser”).

Nuveen Fund Advisors and its affiliate, Teachers Advisors, LLC (“TAL”), are both wholly owned subsidiaries of Nuveen, LLC, the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). As a result of their common ownership by Nuveen, LLC and, ultimately, TIAA, Nuveen Fund Advisors and TAL are considered affiliated persons under common control, and the registered investment companies managed by each are considered to be part of the same group of investment companies.

Certain matters under the 1940 Act, which must be submitted to a vote of the holders of the outstanding voting securities of a series, shall not be deemed to have been effectively acted upon unless approved by the holders of a majority of the outstanding voting securities of the Portfolio.

INVESTMENT RESTRICTIONS

The investment objectives and certain investment policies of the Portfolio are described in the Prospectus. The Portfolio, as a fundamental policy, may not, without the approval of the holders of a majority of the Portfolio’s outstanding voting shares:

(1) Borrow money, except as permitted by the 1940 Act and exemptive orders granted thereunder.

(2) Issue senior securities, except as permitted under the 1940 Act, as interpreted or modified from time to time by any regulatory authority having jurisdiction.

(3) Act as an underwriter of another issuer’s securities, except to the extent that the Portfolio may be deemed to be an underwriter within the meaning of the Securities Act of 1933, as amended, in connection with the purchase and sale of securities and other instruments held in its portfolio.

(4) Purchase or sell real estate unless acquired as a result of ownership of securities or other instruments; but this restriction shall not prevent the Portfolio from purchasing or selling securities or other instruments backed by real estate or interests therein or of issuers engaged in real estate activities.

(5) Purchase or sell physical commodities, unless acquired as a result of ownership of securities or other instruments; but this restriction shall not prohibit the Portfolio from investing in options on commodity indices, commodity futures contracts and options thereon, commodity-related swap agreements, other commodity-related derivative instruments, and investment companies that provide exposure to commodities.

(6) Make loans, except as permitted by the 1940 Act and exemptive orders granted thereunder.

(7) Invest more than 25% of its total assets in securities of issuers in any one industry; provided, however, that such limitations shall not be applicable to Municipal Obligations issued by governments or political subdivisions of governments, and obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities.

(8) Make any investment inconsistent with the Portfolio’s classification as a diversified company under the 1940 Act.

Except with respect to the limitation set forth in number (1) above, the foregoing restrictions and limitations will apply only at the time of purchase of securities, and the percentage limitations will not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of an acquisition of securities, unless otherwise indicated.

For purposes of applying the limitations set forth in numbers (1) and (2) above, under the 1940 Act as currently in effect, the Portfolio is not permitted to issue senior securities, except that the Portfolio may

S-3

borrow from any bank if immediately after such borrowing the value of the Portfolio’s total assets is at least 300% of the principal amount of all of the Portfolio’s borrowings (i.e., the principal amount of the borrowings may not exceed 33⅓% of the Portfolio’s total assets). In the event that such asset coverage shall at any time fall below 300%, the Portfolio shall, within three calendar days thereafter (not including Sundays and holidays), reduce the amount of its borrowings to an extent that the asset coverage of such borrowing shall be at least 300%. No exemptive orders have been issued with respect to the limitation set forth in number (1).

For purposes of applying the limitation set forth in number (6) above, there are no limitations with respect to unsecured loans made by the Portfolio to an unaffiliated party. However, if the Portfolio loans its portfolio securities, the obligation on the part of the Portfolio to return collateral upon termination of the loan could be deemed to involve the issuance of a senior security within the meaning of Section 18(f) of the 1940 Act. In order to avoid violation of Section 18(f), the Portfolio may not make a loan of portfolio securities if, as a result, more than one-third of its total asset value (at market value computed at the time of making a loan) would be on loan. No exemptive orders have been issued with respect to the limitation set forth in number (6).

Where a security is guaranteed by a governmental entity or some other facility, such as a bank guarantee or letter of credit, such a guarantee or letter of credit would be considered a separate security and would be treated as an issue of such government, other entity or bank. Where a security is insured by bond insurance, it shall not be considered a security issued or guaranteed by the insurer; instead the issuer of such security will be determined in accordance with the principles set forth above. The foregoing restrictions do not limit the percentage of the Portfolio’s assets that may be invested in securities insured by any single insurer.

For purposes of applying the limitations set forth in numbers (7) and (8) above, an issuer shall be deemed the sole issuer of a security when its assets and revenues are separate from other governmental entities and its securities are backed only by its assets and revenues. Similarly, in the case of a non-governmental user, such as an industrial corporation or a privately owned or operated hospital, if the security is backed only by the assets and revenues of the non-governmental user, then such non-governmental user would be deemed to be the sole issuer. Where a security is also backed by the enforceable obligation of a superior or unrelated governmental entity or other entity (other than a bond insurer), it shall also be included in the computation of securities owned that are issued by such governmental or other entity.

With respect to the limitation in number (8) above, the Portfolio is currently classified as a diversified fund under the 1940 Act. This means that the Portfolio may not purchase securities of an issuer (other than (i) securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, (ii) repurchase agreements fully collateralized by U.S. government securities, or (iii) securities issued by other investment companies) if, with respect to 75% of its total assets, (i) more than 5% of the Portfolio’s total assets would be invested in securities of that issuer, or (ii) the Portfolio would hold more than 10% of the outstanding voting securities of that issuer. With respect to the remaining 25% of total assets, the Portfolio can invest more than 5% of its assets in one issuer.

The Portfolio has adopted a fundamental investment policy pursuant to Rule 35d-1 under the 1940 Act (the “Name Policy”) whereby the Portfolio, under normal market conditions, will invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. The Portfolio will consider both direct investments and indirect investments (e.g., investments in other investment companies, derivatives and synthetic instruments with economic characteristics similar to the direct investments that meet the

S-4

Name Policy) when determining compliance with the Name Policy. For purposes of the Name Policy, the Portfolio will value eligible derivatives at fair value or market value instead of notional value.

The foregoing fundamental investment policies, together with the investment objectives of the Portfolio, cannot be changed without approval by holders of a “majority of the Portfolio’s outstanding voting shares.” As defined in the 1940 Act, this means the vote of (i) 67% or more of the Portfolio’s shares present at a meeting, if the holders of more than 50% of the Portfolio’s shares are present or represented by proxy, or (ii) more than 50% of the Portfolio’s shares, whichever is less.

In addition to the foregoing fundamental investment policies, the Portfolio is also subject to the following non-fundamental restrictions and policies, which may be changed by the Board of Trustees. The Portfolio may not:

(1) Acquire any illiquid investment if, immediately after the acquisition, the Portfolio would have invested more than 15% of its net assets in illiquid investments.

(2) Invest directly in futures, options on futures and swaps to the extent that the Adviser would be required to register with the Commodity Futures Trading Commission (“CFTC”) as a commodity pool operator. See “Investment Policies and Techniques—Derivatives—Limitations on the Use of CFTC-Regulated Futures, Options on Futures and Swaps.”

For purposes of number (1) above, the Portfolio will monitor portfolio liquidity on an ongoing basis and, in the event that more than 15% of the Portfolio’s net assets are invested in illiquid investments, the Portfolio will reduce such holdings to at or below the 15% limit within a reasonable period of time. The term “illiquid investments” has the same meaning as given in Rule 22e-4 under the 1940 Act and associated guidance.

INVESTMENT POLICIES AND TECHNIQUES

The following information supplements the discussion of the Portfolio’s investment objectives, principal investment strategies, policies and techniques that appears in the Prospectus for the Portfolio. Additional information concerning principal investment strategies of the Portfolio, and other investment strategies that may be used by the Portfolio, is set forth below in alphabetical order.

References in this section to the Adviser also apply, to the extent applicable, to the Sub-Adviser of the Portfolio.

Asset Coverage Requirements

Consistent with the Securities and Exchange Commission ("SEC") staff guidance, the Portfolio will only engage in transactions that expose it to an obligation to another party if it owns either (a) an offsetting position for the same type of financial asset or (b) cash or liquid securities, designated on the Portfolio’s books or held in a segregated account, with a value sufficient at all times to cover its potential obligations not covered as provided in (a). Examples of transactions governed by these asset coverage requirements include, for example, futures contracts and options on futures contracts, swaps and when-issued and delayed delivery transactions. Assets used as offsetting positions, designated on the Portfolio’s books, or held in a segregated account cannot be sold while the positions requiring cover are open unless replaced with other appropriate assets. As a result, the commitment of a large portion of

S-5

assets to be used as offsetting positions or to be designated or segregated in such a manner could impede portfolio management or the ability to meet redemption requests or other current obligations.

To the extent the Portfolio writes a credit default swap, the Portfolio must set aside or earmark liquid assets equal to such contracts’ full notional value (generally, the total numerical value of the asset underlying a credit default swap at the time of valuation) while the positions are open. In the case of long positions in futures contracts that are not contractually required to cash settle, the Portfolio may set aside or earmark liquid assets or enter into offsetting positions equal to such contracts’ full notional value, less any margin on deposit for liquid assets, while the positions are open. In the case of short positions in futures contracts that are not contractually required to cash settle, the Portfolio may set aside or earmark liquid assets or enter into offsetting positions equal to such contracts’ current market value, less any margin on deposit for liquid assets, while the positions are open. With respect to futures contracts that are contractually required to cash settle, however, the Portfolio is permitted to set aside or earmark liquid assets or enter into an offsetting position in an amount equal to the Portfolio’s daily mark-to-market net obligation (i.e., the Portfolio’s daily net liability) under the contracts, if any, rather than such contracts’ full notional value. By setting aside or earmarking assets equal to only its net obligations under cash-settled futures contracts, the Portfolio may employ leverage to a greater extent than if the Portfolio were required to segregate assets equal to the full notional value of such contracts.

Borrowing

Joint Credit Agreement

Inter-Fund Borrowing and Lending

The SEC has granted an exemptive order permitting registered open-end and closed-end Nuveen Funds to participate in an inter-fund lending facility whereby the Nuveen Funds may directly lend to and borrow money from each other for temporary purposes (e.g., to satisfy redemption requests or when a sale of securities “fails,” resulting in an unanticipated cash shortfall) (the “Inter-Fund Program”). The closed-end Nuveen Funds will participate only as lenders, and not as borrowers, in the Inter-Fund Program because such closed-end funds rarely, if ever, need to borrow cash to meet redemptions. The Inter-Fund Program is subject to a number of conditions, including, among other things, the requirements that (1) no Nuveen Fund may borrow or lend money through the Inter-Fund Program unless it receives a more favorable interest rate than is typically available from a bank or other financial institution for a comparable transaction; (2) no Nuveen Fund may borrow on an unsecured basis through the Inter-Fund Program unless the Nuveen Fund’s outstanding borrowings from all sources immediately after the inter-fund borrowing total 10% or less of its total assets; provided that if the borrowing Nuveen Fund has a secured borrowing outstanding from any other lender, including but not limited to another Nuveen Fund,

S-6

the inter-fund loan must be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan value; (3) if a Nuveen Fund’s total outstanding borrowings immediately after an inter-fund borrowing would be greater than 10% of its total assets, the Nuveen Fund may borrow through the inter-fund loan on a secured basis only; (4) no Nuveen Fund may lend money if the loan would cause its aggregate outstanding loans through the Inter-Fund Program to exceed 15% of its net assets at the time of the loan; (5) a Nuveen Fund’s inter-fund loans to any one Nuveen Fund shall not exceed 5% of the lending Nuveen Fund’s net assets; (6) the duration of inter-fund loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days; and (7) each inter-fund loan may be called on one business day’s notice by a lending Nuveen Fund and may be repaid on any day by a borrowing Nuveen Fund. In addition, a Nuveen Fund may participate in the Inter-Fund Program only if and to the extent that such participation is consistent with the Nuveen Fund’s investment objective(s) and investment policies. The Board of Trustees of the Nuveen Funds is responsible for overseeing the Inter-Fund Program.

The limitations detailed above and the other conditions of the SEC exemptive order permitting the Inter-Fund Program are designed to minimize the risks associated with Inter-Fund Program for both the lending fund and the borrowing fund. However, no borrowing or lending activity is without risk. When the Portfolio borrows money from another Nuveen Fund, there is a risk that the loan could be called on one day’s notice or not renewed, in which case the Portfolio may have to borrow from a bank at a higher rate or take other actions to payoff such loan if an inter-fund loan is not available from another Nuveen Fund. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

Derivatives

Subject to the limitations set forth below under “Limitations on the Use of CFTC-Regulated Futures, Options on Futures and Swaps,” the Portfolio may use derivative instruments as described below. Generally, a derivative is a financial contract the value of which depends upon, or is derived from, the value of an underlying asset, reference rate or index. Derivatives generally take the form of contracts under which the parties agree to payments between them based upon the performance of a wide variety of underlying references, such as stocks, bonds, loans, commodities, interest rates, currency exchange rates, and various domestic and foreign indices.

The Portfolio may use derivatives for a variety of reasons, including as a substitute for investing directly in securities, as part of a hedging strategy (that is, for the purpose of reducing risk to the Portfolio), to manage the effective duration of the Portfolio’s portfolio, or for other purposes related to the management of the Portfolio. Derivatives permit the Portfolio to increase or decrease the level of risk, or change the character of the risk, to which its portfolio is exposed in much the same way as the Portfolio can increase or decrease the level of risk, or change the character of the risk, of its portfolio by making investments in specific securities. However, derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on the Portfolio’s performance.

While transactions in some derivatives may be effected on established exchanges, many other derivatives are privately negotiated and entered into in the over-the-counter (“OTC”) market with a single counterparty. When exchange-traded derivatives are purchased and sold, a clearing agency associated with the exchange stands between each buyer and seller and effectively guarantees performance of each contract, either on a limited basis through a guaranty fund or to the full extent of the clearing agency’s balance sheet. Transactions in OTC derivatives not subject to a clearing requirement have no such protection. Each party to an uncleared OTC derivative bears the risk that its direct counterparty will default. In addition, OTC derivatives are generally less liquid than exchange-traded derivatives because they often can only be closed out with the other party to the transaction.

The use of derivative instruments is subject to applicable regulations of the SEC, the CFTC, various state regulatory authorities and, with respect to exchange-traded derivatives, the several exchanges upon which they are traded. As discussed above under “Asset Coverage Requirements,” in order to engage in certain transactions in derivatives, the Portfolio may be required to hold offsetting positions or to hold cash or liquid securities in a segregated account or designated on the Portfolio’s books. In addition, the Portfolio’s ability to use derivative instruments may be limited by tax considerations.

The particular derivative instruments the Portfolio can use are described below. The Portfolio’s portfolio manager may decide not to employ some or all of these instruments, and there is no assurance that any derivatives strategy used by the Portfolio will succeed. The Portfolio may employ new derivative

S-7

instruments and strategies when they are developed, if those investment methods are consistent with the Portfolio’s investment objectives and are permissible under applicable regulations governing the Portfolio.

Futures

The Portfolio may engage in futures transactions. The Portfolio may buy and sell futures contracts that relate to (1) interest rates, (2) debt securities and (3) bond indices. The Portfolio may only enter into futures contracts which are standardized and traded on a U.S. or foreign exchange, board of trade or similar entity, or quoted on an automated quotation system.

A futures contract is an agreement between two parties to buy and sell a security, index or interest rate (each a “financial instrument”) for a set price on a future date. Certain futures contracts, such as futures contracts relating to individual securities, call for making or taking delivery of the underlying financial instrument. However, these contracts generally are closed out before delivery by entering into an offsetting purchase or sale of a matching futures contract. Other futures contracts, such as futures contracts on interest rates and indices, do not call for making or taking delivery of the underlying financial instrument, but rather are agreements pursuant to which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the financial instrument at the close of the last trading day of the contract and the price at which the contract was originally written. These contracts also may be settled by entering into an offsetting futures contract.

Unlike when the Portfolio purchases or sells a security, no price is paid or received by the Portfolio upon the purchase or sale of a futures contract. Initially, the Portfolio will be required to deposit with its futures broker (also known as a futures commission merchant (“FCM”)) an amount of cash or securities equal to a specified percentage of the contract amount. This amount is known as initial margin. The margin deposit is intended to ensure completion of the contract. Minimum initial margin requirements are established by the futures exchanges and may be revised. In addition, FCMs may establish margin deposit requirements that are higher than the exchange minimums. Cash held as margin is generally invested by the FCM in high-quality instruments permitted under CFTC regulations, with returns retained by the FCM and interest paid to the Portfolio on the cash at an agreed-upon rate. The Portfolio will also receive any interest paid from coupon-bearing securities, such as Treasury securities, held in margin accounts. Subsequent payments to and from the FCM, called variation margin, will be made on a daily basis as the price of the underlying financial instrument fluctuates, making the futures contract more or less valuable, a process known as marking the contract to market. Changes in variation margin are recorded by the Portfolio as unrealized gains or losses. At any time prior to expiration of the futures contract, the Portfolio may elect to close the position by taking an opposite position that will operate to terminate its position in the futures contract. A final determination of variation margin is then made, additional cash is required to be paid by or released to the Portfolio, and the Portfolio realizes a gain or loss. In the event of the bankruptcy or insolvency of an FCM that holds margin on behalf of the Portfolio, the Portfolio may be entitled to the return of margin owed to it only in proportion to the amount received by the FCM’s other customers, potentially resulting in losses to the Portfolio. Futures transactions also involve brokerage costs.

Most U.S. futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The 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 at the end of a trading session. Once the daily limit has been reached in a particular type of futures contract, no trades may be made on that day at a price beyond that limit. The daily limit governs only price movement during a particular trading day and therefore does not limit potential losses, because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses.

Options on Futures

The Portfolio may purchase or write put and call options on futures contracts and write straddles, which consist of a call and put option on the same futures contract. A futures option gives the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price prior to the expiration of the option. Upon exercise of a call option, the holder acquires a long position in the futures contract and the writer is assigned the opposite short position. In the case of a put option, the opposite is true. Prior to exercise or expiration, a futures option may be closed out by an offsetting purchase or sale of a futures option of the same series.

S-8

The Portfolio may use options on futures contracts in connection with hedging strategies. The writing of a call option or the purchasing of a put option on a futures contract constitutes a partial hedge against declining prices of the securities which are deliverable upon exercise of the futures contract. If the futures price at expiration of a written call option is below the exercise price, the Portfolio will retain the full amount of the option premium which provides a partial hedge against any decline that may have occurred in the Portfolio’s holdings of securities. If the futures price when the option is exercised is above the exercise price, however, the Portfolio will incur a loss, which may be offset, in whole or in part, by the increase in the value of the securities held by the Portfolio that were being hedged. Writing a put option or purchasing a call option on a futures contract serves as a partial hedge against an increase in the value of the securities the Portfolio intends to acquire.

When writing a call option, the Portfolio must either segregate liquid assets with a value equal to the fluctuating market value of the optioned futures contract, or the Portfolio must own an option to purchase the same futures contract having an exercise price that is (i) equal to or less than the exercise price of the call written, or (ii) greater than the exercise price of the call written, provided the difference is maintained by the Portfolio in segregated liquid assets.

When writing a put option, the Portfolio must segregate liquid assets in an amount not less than the exercise price, or own a put option on the same futures contract where the exercise price of the put held is (i) equal to or greater than the exercise price of the put written, or (ii) less than the exercise price of the put written, provided the difference is maintained by the Portfolio in segregated liquid assets.

When the Portfolio writes a straddle, sufficient assets will be segregated to meet the Portfolio’s immediate obligations. The Portfolio may segregate the same liquid assets for both the call and put options in a straddle where the exercise price of the call and put are the same, or the exercise price of the call is higher than that of the put. In such cases, the Portfolio will also segregate liquid assets equivalent to the amount, if any, by which the put is “in the money.”

As with investments in futures contracts, the Portfolio is required to deposit and maintain margin with respect to put and call options on futures contracts written by it.

Swap Transactions

The Portfolio may enter into interest rate, total return and credit default swap agreements, along with other swap agreements for any purpose consistent with the Portfolio’s investment objectives. The Portfolio may also enter into options on the foregoing types of swap agreements (“swap options”).

The Portfolio may enter into swap transactions for any purpose consistent with its investment objectives and strategies, such as for the purpose of attempting to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets, as a duration management technique, to protect against an increase in the price of securities the Portfolio anticipates purchasing at a later date, to reduce risk arising from the ownership of a particular instrument, or to gain exposure to certain securities, reference rates, sectors or markets.

Swap agreements are two party contracts entered into primarily by institutional investors for a specified period of time. In a standard swap transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on a particular predetermined asset, reference rate or index. The gross returns to be exchanged or swapped between the parties are generally calculated with respect to a notional amount, e.g., the return on or increase in value of a particular dollar amount invested at a particular interest rate or in a basket of securities representing a particular index. The notional amount of the swap agreement generally is only used as a basis upon which to calculate the obligations that the parties to the swap agreement have agreed to exchange. The Portfolio’s current obligations under a net swap agreement will be accrued daily (offset against any amounts owed to the Portfolio) and the Portfolio will segregate assets determined to be liquid by the Sub-Adviser for any accrued but unpaid net amounts owed to a swap counterparty. See “Asset Coverage Requirements” above.

Interest Rate Swaps. Interest rate swaps are financial instruments that involve the exchange of one type of interest rate for another type of interest rate cash flow on specified dates in the future. Some of the different types of interest rate swaps are “fixed-for-floating rate swaps,” “termed basis swaps” and “index amortizing swaps.” Fixed-for-floating rate swaps involve the exchange of fixed interest rate cash flows for floating rate cash flows. Termed basis swaps entail cash flows to both parties based on floating interest rates, where the interest rate indices are different. Index amortizing swaps are typically fixed-for-floating swaps where the notional amount changes if certain conditions are met. Like a traditional

S-9

investment in a debt security, the Portfolio could lose money by investing in an interest rate swap if interest rates change adversely.

Total Return Swaps. In a total return swap, one party agrees to pay the other the “total return” of a defined underlying asset during a specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. A total return swap may be applied to any underlying asset but is most commonly used with equity indices, single stocks, bonds and defined baskets of loans and mortgages. The Portfolio might enter into a total return swap involving an underlying index or basket of securities to create exposure to a potentially widely-diversified range of securities in a single trade. An index total return swap can be used by the portfolio manager to assume risk, without the complications of buying the component securities from what may not always be the most liquid of markets.

Credit Default Swaps. A credit default swap is a bilateral contract that enables an investor to buy or sell protection against a defined-issuer credit event. The Portfolio may enter into credit default swap agreements either as a buyer or a seller. The Portfolio may buy protection to attempt to mitigate the risk of default or credit quality deterioration in one or more of its individual holdings or in a segment of the fixed income securities market to which it has exposure, or to take a “short” position in individual bonds or market segments which it does not own. The Portfolio may sell protection in an attempt to gain exposure to the credit quality characteristics of particular bonds or market segments without investing directly in those bonds or market segments.

As the buyer of protection in a credit default swap, the Portfolio will pay a premium (by means of an upfront payment or a periodic stream of payments over the term of the agreement) in return for the right to deliver a referenced bond or group of bonds to the protection seller and receive the full notional or par value (or other agreed upon value) upon a default (or similar event) by the issuer(s) of the underlying referenced obligation(s). If no default occurs, the protection seller would keep the stream of payments and would have no further obligation to the Portfolio. Thus, the cost to the Portfolio would be the premium paid with respect to the agreement. If a credit event occurs, however, the Portfolio may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. The Portfolio bears the risk that the protection seller may fail to satisfy its payment obligations.

If the Portfolio is a seller of protection in a credit default swap and no credit event occurs, the Portfolio would generally receive an up-front payment or a periodic stream of payments over the term of the swap. If a credit event occurs, however, generally the Portfolio would have to pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. As the protection seller, the Portfolio effectively adds economic leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the

S-10

Portfolio is subject to investment exposure on the notional amount of the swap. Thus, the Portfolio bears the same risk as it would by buying the reference obligations directly, plus the additional risks related to obtaining investment exposure through a derivative instrument discussed below under “Risks Associated with Swap Transactions.”

Swap Options. A swap option is a contract that gives a counterparty the right (but not the obligation), in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement at some designated future time on specified terms. A cash-settled option on a swap gives the purchaser the right, in return for the premium paid, to receive an amount of cash equal to the value of the underlying swap as of the exercise date. The Portfolio may write (sell) and purchase put and call swap options. Depending on the terms of the particular option agreement, the Portfolio generally will incur a greater degree of risk when it writes a swap option than when it purchases a swap option. When the Portfolio purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Portfolio writes a swap option, upon exercise of the option the Portfolio will become obligated according to the terms of the underlying agreement.

Risks Associated with Swap Transactions. The use of swap transactions is a highly specialized activity which involves strategies and risks different from those associated with ordinary portfolio security transactions. If the Sub-Adviser is incorrect in its forecasts of default risks, market spreads or other applicable factors the investment performance of the Portfolio would diminish compared with what it would have been if these techniques were not used. As the protection seller in a credit default swap, the Portfolio effectively adds economic leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Portfolio is subject to investment exposure on the notional amount of the swap. The Portfolio may only close out a swap or other two-party contract with its particular counterparty, and may only transfer a position with the consent of that counterparty. In addition, the price at which the Portfolio may close out such a two party contract may not correlate with the price change in the underlying reference asset. If the counterparty defaults, the Portfolio will have contractual remedies, but there can be no assurance that the counterparty will be able to meet its contractual obligations or that the Portfolio will succeed in enforcing its rights. It also is possible that developments in the derivatives market, including potential government regulation, could adversely affect the Portfolio’s ability to terminate existing swap or other agreements or to realize amounts to be received under such agreements.

Interest Rate Caps, Collars and Floors

The Portfolio may enter into interest rate caps, floors and collars. Caps and floors have an effect similar to buying or writing options. In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed-upon level. The seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed-upon level. An interest rate collar involves selling a cap and purchasing a floor or vice versa to protect the Portfolio against interest rate movements exceeding given minimum or maximum levels.

Limitations on the Use of CFTC-Regulated Futures, Options on Futures and Swaps

The Portfolio will limit its direct investments in CFTC-regulated futures, options on futures and swaps (“CFTC Derivatives”) to the extent necessary for the Adviser to claim the exclusion from regulation as a commodity pool operator with respect to the Portfolio under CFTC Rule 4.5, as such rule may be amended from time to time. Under Rule 4.5 as currently in effect, the Portfolio will limit its trading activity in CFTC Derivatives (excluding activity for “bona fide hedging purposes,” as defined by the CFTC) such that it meets one of the following tests:

· Aggregate initial margin and premiums required to establish its positions in CFTC Derivatives do not exceed 5% of the liquidation value of the Portfolio’s portfolio, after taking into account unrealized profits and losses on such positions; or

· Aggregate net notional value of its positions in CFTC Derivatives does not exceed 100% of the liquidation value of the Portfolio’s portfolio, after taking into account unrealized profits and losses on such positions.

With respect to the Portfolio, the Adviser has filed a notice of eligibility for exclusion from the definition of the term commodity pool operator under the Commodity Exchange Act and therefore is not subject to registration or regulation as a commodity pool operator thereunder.

The requirements for qualification as a regulated investment company may also limit the extent to which the Portfolio may invest in CFTC Derivatives. See “Tax Matters—Qualification as a Regulated Investment Company.”

Federal Income Tax Treatment of Futures Contracts and Options

The Portfolio’s transactions in futures contracts and options will be subject to special provisions of the Internal Revenue Code of 1986, as amended (the “Code”), that, among other things, may affect the character of gains and losses realized by the Portfolio (i.e., may affect whether gains or losses are ordinary or capital, or short-term or long-term), may accelerate recognition of income to the Portfolio and may defer Portfolio losses. These rules could, therefore, affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require the Portfolio to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out) and (b) may cause the Portfolio to recognize income without receiving cash with which to make distributions in amounts necessary to satisfy the 90% distribution requirement for qualifying to be taxed as a regulated investment company and the distribution requirement for avoiding excise taxes.

Risks and Special Considerations Concerning Derivatives

The use of derivative instruments involves certain general risks and considerations as described below.

(1) Market Risk. Market risk is the risk that the value of the underlying assets may go up or down. Adverse movements in the value of an underlying asset can expose the Portfolio to losses. The successful use of derivative instruments depends upon a variety of factors, particularly the portfolio manager's ability to predict movements in the relevant markets, which may require different skills than predicting changes in the prices of individual securities. There can be no assurance that any particular strategy adopted will succeed.

(2) Counterparty Risk. Counterparty risk is the risk that a loss may be sustained as a result of the failure of a counterparty to comply with the terms of a derivative instrument. The counterparty risk for exchange-traded derivatives is generally less than for OTC derivatives, since generally a clearing agency, which is the issuer or counterparty to each exchange-traded instrument, provides a guarantee of performance. For many OTC instruments, there is no similar clearing agency guarantee and there is less regulation or supervision of transactions. In all transactions, the Portfolio will bear the risk that the counterparty will default, and this could result in a loss of the expected benefit of the derivative transactions and possibly other losses to the Portfolio. The Portfolio will enter into derivatives transactions only with counterparties that its portfolio manager reasonably believes are capable of performing under the contract.

(3) Correlation Risk. Correlation risk is the risk that there might be an imperfect correlation, or even no correlation, between price movements of a derivative instrument and price movements of investments being hedged. When a derivative transaction is used to completely hedge another position, changes in the market value of the combined position (the derivative instrument plus the position being hedged) result from an imperfect correlation between the price movements of the two instruments. With a perfect hedge, the value of the combined position remains unchanged with any change in the price of the underlying asset. With an imperfect hedge, the value of the derivative instrument and its hedge are not perfectly correlated. For example, if the value of a derivative instrument used in a short hedge (such as writing a call option, buying a put option or selling a futures contract) increased by less than the decline in value of the hedged investments, the hedge would not be perfectly correlated. This might occur due to factors unrelated to the value of the investments being hedged, such as speculative or other pressures on the markets in which these instruments are traded. The effectiveness of hedges using instruments on indices will depend, in part, on the degree of correlation between price movements in the index and the price movements in the investments being hedged.

(4) Liquidity Risk. Liquidity risk is the risk that a derivative instrument cannot be sold, closed out or replaced quickly at or very close to its fundamental value. Generally, exchange contracts are very liquid because the exchange clearinghouse is the counterparty of every contract. OTC transactions are less liquid than exchange-traded derivatives since they often can only be closed out with the other

S-12

party to the transaction. The Portfolio might be required by applicable regulatory requirements to maintain assets as “cover,” maintain segregated accounts, and/or make margin payments when it takes positions in derivative instruments involving obligations to third parties (i.e., instruments other than purchase options). If the Portfolio is unable to close out its positions in such instruments, it might be required to continue to maintain such assets or accounts or make such payments until the position expires, matures or is closed out. These requirements might impair the Portfolio’s ability to sell a security or make an investment at a time when it would otherwise be favorable to do so, or require that the Portfolio sell a portfolio security at a disadvantageous time. The Portfolio’s ability to sell or close out a position in an instrument prior to expiration or maturity depends upon the existence of a liquid secondary market or, in the absence of such a market, the ability and willingness of the counterparty to enter into a transaction closing out the position. There is no assurance that any derivatives position can be sold or closed out at a time and price that is favorable to the Portfolio.

(5) Legal Risk. Legal risk is the risk of loss caused by the unenforceability of a party’s obligations under the derivative. While a party seeking price certainty agrees to surrender the potential upside in exchange for downside protection, the party taking the risk is looking for a positive payoff. Despite this voluntary assumption of risk, a counterparty that has lost money in a derivative transaction may try to avoid payment by exploiting various legal uncertainties about certain derivative products.

(6) Systemic or “Interconnection” Risk. Systemic or interconnection risk is the risk that a disruption in the financial markets will cause difficulties for all market participants. In other words, a disruption in one market will spill over into other markets, perhaps creating a chain reaction. Much of the OTC derivatives market takes place among the OTC dealers themselves, thus creating a large interconnected web of financial obligations. This interconnectedness raises the possibility that a default by one large dealer could create losses for other dealers and destabilize the entire market for OTC derivative instruments.

(7) Leverage Risk. Leverage risk is the risk that the Portfolio may be more volatile than if it had not been leveraged due to leverage’s tendency to exaggerate the effect of any increase or decrease in the value of the Portfolio’s portfolio securities. The use of leverage may also cause the Portfolio to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet segregation requirements.

S-13

Mortgage-Backed Securities

The Portfolio may invest in fixed-income obligations backed by a pool of mortgages. Mortgage-backed securities are issued both by U.S. government agencies, including the Government National Mortgage Association (“GNMA”), the Federal National Mortgage Association (“FNMA”) and the Federal Home Loan Mortgage Corporation (“FHLMC”), and by private entities. The payment of interest and principal on securities issued by U.S. government agencies is guaranteed by the full faith and credit of the U.S. government (in the case of GNMA securities) or the issuer (in the case of FNMA and FHLMC securities). However, the guarantees do not apply to the market prices and yields of these securities, which vary with changes in interest rates. Mortgage-backed securities issued by private entities are structured similarly to mortgage-backed securities issued by GNMA, FNMA and FHLMC. These securities and the underlying mortgages are not guaranteed by government agencies. However, these securities generally are structured with one or more types of credit enhancement by a third party. Mortgage-backed securities permit borrowers to prepay their underlying mortgages. Prepayments by borrowers on underlying obligations can alter the effective maturity of these instruments.

Municipal Bonds and Other Municipal Obligations

The Portfolio invests principally in municipal bonds and other municipal obligations. These bonds and other obligations are issued by the states and by their local and special-purpose political subdivisions. The term “municipal bond” includes short-term municipal notes issued by the states and their political subdivisions, including, but not limited to, tax anticipation notes (“TANs”), bond anticipation notes (“BANs”), revenue anticipation notes (“RANs”), construction loan notes, tax free commercial paper, and tax free participation certificates. In general, municipal obligations include debt obligations issued by states, cities and local authorities to obtain funds for various public purposes, including construction of a wide range of public facilities such as airports, bridges, highways, hospitals, housing, mass transportation, schools, streets and water and sewer works.

General obligation bonds are backed by the issuer’s pledge of its faith, credit, and taxing power for the payment of principal and interest. The taxes that can be levied for the payment of debt service may be limited or unlimited as to rate and amount. For a limited obligation or revenue bond, the only security is typically the net revenue derived from payments by a particular facility or class of facilities financed by the proceeds of the bonds or, in some cases, from the proceeds of a special tax or other special revenues. Although the security behind these bonds varies widely, many lower rated bonds provide additional security in the form of a debt service reserve fund that may also be used to make principal and interest payments on the issuer’s obligations. In addition, some revenue obligations (as well as general obligations) are insured by a bond insurance company or backed by a letter of credit issued by a banking institution. The credit quality of revenue bonds is usually directly related to the credit standing of the user of the facility being financed or of an institution which provides a guarantee, letter of credit or other credit enhancement for the bond issue. Revenue bonds do not generally constitute the pledge of the credit of the issuer of such bonds and are generally not secured by the taxing power of the municipality. Revenue bonds are included in the term municipal obligations if the interest paid thereon is exempt from federal income tax. Revenue bonds may include, but are not limited to, pollution control, health care, housing, education-related and industrial development bonds.

S-14

Generally, the creditworthiness of a local municipal obligation is unrelated to that of the municipal obligations of the state itself if the state has no responsibility to guarantee or otherwise make payments on those local municipal obligations.

Obligations of issuers of municipal obligations are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors. The application of state law to municipal obligation issuers could produce varying results among the states or among municipal obligation issuers within a state. These uncertainties could have a significant impact on the prices of the municipal obligations in which the Portfolio invests. In addition, issuers of municipal obligations may become subject to the laws enacted in the future by Congress, state legislatures or referenda extending the time for payment of principal and/or interest, or imposing other constraints upon enforcement of such obligations or upon municipalities to levy taxes. There is also the possibility that, as a result of legislation or other conditions, the power or ability of any issuer to pay, when due, the principal of and interest on its municipal obligations may be materially affected.

Municipal Bonds

The two general classifications of municipal bonds are “general obligation” bonds and “revenue” bonds. General obligation bonds are secured by the governmental issuer’s pledge of its faith, credit and taxing power for the payment of principal and interest upon a default by the issuer of its principal and interest payment obligations. They are usually paid from general revenues of the issuing governmental entity. Revenue bonds, on the other hand, are usually payable only out of a specific revenue source rather than from general revenues. Revenue bonds ordinarily are not backed by the faith, credit or general taxing power of the issuing governmental entity. The principal and interest on revenue bonds for private facilities are typically paid out of rents or other specified payments made to the issuing governmental entity by a private company which uses or operates the facilities. Examples of these types of obligations are industrial revenue bond and pollution control revenue bonds. Industrial revenue bonds are issued by governmental entities to provide financing aid to community facilities such as hospitals, hotels, business or residential complexes, convention halls and sport complexes. Pollution control revenue bonds are issued to finance air, water and solids pollution control systems for privately operated industrial or commercial facilities.

Revenue bonds for private facilities usually do not represent a pledge of the credit, general revenues or taxing powers of issuing governmental entity. Instead, the private company operating the facility is the sole source of payment of the obligation. Sometimes, the funds for payment of revenue bonds come solely from revenue generated by operation of the facility. Federal income tax laws place substantial limitations on industrial revenue bonds, and particularly certain specified private activity bonds issued after August 7, 1986. In the future, legislation could be introduced in Congress which could further restrict or eliminate the income tax exemption for interest on debt obligations in which the Portfolio may invest.

Refunded Bonds

The Portfolio may invest in refunded bonds. Refunded bonds may have originally been issued as general obligation or revenue bonds, but become refunded when they are secured by an escrow fund, usually consisting entirely of direct U.S. government obligations and/or U.S. government agency obligations sufficient for paying the bondholders. There are two types of refunded bonds: pre-refunded bonds and escrowed-to-maturity (“ETM”) bonds. The escrow fund for a pre-refunded municipal bond may be structured so that the refunded bonds are to be called at the first possible date or a subsequent call

S-15

date established in the original bond debenture. The call price usually includes a premium from 1% to 3% above par. This type of structure usually is used for those refundings that either reduce the issuer’s interest payment expenses or change the debt maturity schedule. In escrow funds for ETM refunded municipal bonds, the maturity schedules of the securities in the escrow funds match the regular debt-service requirements on the bonds as originally stated in the bond indentures.

Municipal Leases and Certificates of Participation

The Portfolio also may purchase municipal lease obligations, primarily through certificates of participation. Certificates of participation in municipal leases are undivided interests in a lease, installment purchase contract or conditional sale contract entered into by a state or local governmental unit to acquire equipment or facilities. Municipal leases frequently have special risks which generally are not associated with general obligation bonds or revenue bonds. Municipal leases and installment purchase or conditional sales contracts (which usually provide for title to the leased asset to pass to the governmental issuer upon payment of all amounts due under the contract) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of municipal debt.

Although lease obligations do not constitute general obligations of the municipality for which the municipality’s taxing power is pledged, a lease obligation is ordinarily backed by the municipality’s covenant to budget for, appropriate and make the payments due under the lease obligation. However, certain lease obligations contain “non-appropriation” clauses, which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. In evaluating securities for purchase, the Portfolio will take into account the incentive of the issuer to appropriate under the lease, among other factors. Some lease obligations may be illiquid under certain circumstances. Although non-appropriation lease obligations are secured by the leased equipment or facilities, disposition of the property in the event of foreclosure might prove difficult and time consuming. In addition, disposition upon non-appropriation or foreclosure might not result in recovery by the Portfolio of the full principal amount represented by an obligation.

Derivative Municipal Securities

The Portfolio may also acquire derivative municipal securities, which are custodial receipts of certificates underwritten by securities dealers or banks that evidence ownership of future interest payments, principal payments or both on certain municipal securities. The underwriter of these certificates or receipts typically purchases municipal securities and deposits them in an irrevocable trust or custodial account with a custodian bank, which then issues receipts or certificates that evidence ownership of the periodic unmatured coupon payments and the final principal payment on the obligation.

The principal and interest payments on the municipal securities underlying custodial receipts may be allocated in a number of ways. For example, payments may be allocated such that certain custodial receipts may have variable or floating interest rates and others may be stripped securities which pay only the principal or interest due on the underlying municipal securities. The Portfolio may invest in custodial receipts which have inverse floating interest rates and other inverse floating rate municipal obligations, as described below under “Inverse Floating Rate Municipal Securities.”

Variable Rate Demand Notes (“VRDNs”)

VRDNs are long-term municipal obligations that have variable or floating interest rates and provide the Portfolio with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most VRDNs allow the Portfolio to demand the repurchase of the security on not more than seven days

S-16

prior notice. Other notes only permit the Portfolio to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of municipal obligations from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate municipal obligations than for fixed income obligations.

Inverse Floating Rate Municipal Securities

The Portfolio may invest in inverse floating rate municipal securities or “inverse floaters,” whose rates vary inversely to interest rates on a specified short-term municipal bond index or on another instrument. Such securities involve special risks as compared to conventional fixed-rate bonds. Should short-term interest rates rise, the Portfolio’s investment in inverse floaters likely would adversely affect the Portfolio’s earnings and distributions to shareholders. Also, because changes in the interest rate on the other index or other instrument inversely affect the rate of interest received on an inverse floater, and because inverse floaters essentially represent a leveraged investment in a long-term bond, the value of an inverse floater is generally more volatile than that of a conventional fixed-rate bond having similar credit quality, redemption provisions and maturity. Although volatile in value, inverse floaters typically offer the potential for yields substantially exceeding the yields available on conventional fixed-rate bonds with comparable credit quality, coupon, call provisions and maturity. The markets for inverse floating rate securities may be less developed and have less liquidity than the markets for conventional securities. The Portfolio will only invest in inverse floating rate securities whose underlying bonds are rated A or higher.

Non-Investment Grade Debt Securities (Junk Bonds)

The Portfolio may invest in non-investment grade debt securities. Non-investment grade debt securities are medium- to low-quality municipal obligations. Municipal obligations rated below investment grade (BB/Ba or lower) are commonly known as “high yield,” “high risk” or “junk” bonds. Junk bonds, while generally offering higher yields than investment grade securities with similar maturities, involve greater risks, including the possibility of default or bankruptcy. They are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal. The special risk considerations in connection with investments in these securities are discussed below. Refer to Appendix A of this Statement of Additional Information for a discussion of securities ratings.

(1) Effect of Interest Rates and Economic Changes. All interest-bearing securities typically experience appreciation when interest rates decline and depreciation when interest rates rise. In addition, the market values of junk bond securities tend to reflect individual issuer developments to a greater extent than do the market values of higher rated securities, which react primarily to fluctuations in the general level of interest rates. Junk bond securities also tend to be more sensitive to economic conditions than are higher rated securities. As a result, they generally involve more credit risk than securities in the higher rated categories. During an economic downturn or a sustained period of rising interest rates, highly leveraged issuers of junk bond securities may experience financial stress and may not have sufficient revenues to meet their payment obligations. The risk of loss due to default by an issuer of these securities is significantly greater than by an issuer of higher rated securities because such securities are generally unsecured and are often subordinated to other creditors. Further, if the issuer of a junk bond security defaults, the Portfolio may incur additional expenses to seek recovery. Periods of economic uncertainty and changes would also generally result in increased volatility in the market prices of these and thus in the Portfolio’s net asset value.

The value of a junk bond security will generally decrease in a rising interest rate market and, accordingly, so will the Portfolio’s net asset value. If the Portfolio experiences unexpected net redemptions in such a market, it may be forced to liquidate a portion of its portfolio securities without regard to their investment merits. Due to the limited liquidity of certain junk bond securities, the Portfolio may be forced to liquidate these securities at a substantial discount. Any such liquidation would reduce the Portfolio’s asset base over which expenses could be allocated and could result in a reduced rate of return for the Portfolio.

(2) Payment Expectations. Junk bond securities typically contain redemption, call, or prepayment provisions that permit the issuer of securities containing such provisions to redeem the securities at its discretion. During periods of falling interest rates, issuers of these securities are likely to redeem or prepay the securities and refinance them with debt securities with a lower interest rate. To the extent an issuer is able to refinance the securities, or otherwise redeem them, the Portfolio may have to replace the securities with lower yielding securities, which could result in a lower return for the Portfolio.

S-17

(3) Credit Ratings. Credit ratings are issued by credit rating agencies and are indicative of the rated securities’ safety of principal and interest payments. They do not, however, evaluate the market value risk of junk bond securities and, therefore, may not fully reflect the true risks of such an investment. In addition, credit rating agencies may not make timely changes in a rating to reflect changes in the economy or in the condition of the issuer that affect the value of the security. Consequently, credit ratings are used only as a preliminary indicator of investment quality. Investments in junk bonds will depend more upon credit analysis by the Sub-Adviser than investments in investment grade debt securities. The Sub-Adviser employs its own credit research and analysis, which includes a study of the issuer’s existing debt, capital structure, ability to service debts and pay dividends, sensitivity to economic conditions, operating history, and current earnings trend. The Sub-Adviser continually monitors the Portfolio’s investments and carefully evaluates whether to dispose of or to retain junk bond securities whose credit ratings or credit quality may have changed.

(4) Liquidity and Valuation. The Portfolio may have difficulty disposing of certain junk bond securities because there may be a thin trading market for such securities. Not all dealers maintain markets in all junk bond securities. As a result, there is no established retail secondary market for many of these securities. To the extent a secondary trading market does exist, it is generally not as liquid as the secondary market for higher rated securities. The lack of a liquid secondary market may have an adverse impact on the market price of the security. The lack of a liquid secondary market for certain securities may also make it more difficult for the Portfolio to obtain accurate market quotations for purposes of valuing its securities. Market quotations are generally available on many junk bond issues only from a limited number of dealers and may not necessarily represent firm bids of such dealers or prices for actual sales. During periods of thin trading, the spread between bid and asked prices is likely to increase significantly. In addition, adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the value and liquidity of junk bond securities, especially in a thinly traded market.

The Portfolio may invest up to 5% of its net assets in defaulted municipal obligations. Municipal obligations in the lowest rating categories may be in default and are generally regarded as having poor prospects of attaining any real investment standing. A default or expected default in a municipal obligation owned by the Portfolio could result in a significant decline in the value of that municipal obligation. Any investment in distressed or defaulted securities subjects the Portfolio to even greater credit risk than investments in other below-investment grade securities. The Portfolio generally will not receive interest payments on the defaulted bonds and there is a substantial risk that principal will not be repaid. Defaulted bonds may be repaid only after lengthy workout or bankruptcy proceedings, during which the issuer may not make any interest or other payments. The Portfolio may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal of or interest on its portfolio holdings. In any reorganization or liquidation proceeding relating to a defaulted bond, the Portfolio may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Defaulted bonds and any securities received in exchange for defaulted bonds may be subject to restrictions on resale.

Payment-In-Kind Debentures and Delayed Interest Securities

The Portfolio may invest in debentures the interest on which may be paid in other securities rather than cash (“PIKs”) or may be delayed (“delayed interest securities”). Typically, during a specified term prior to the debenture’s maturity, the issuer of a PIK may provide for the option or the obligation to make interest payments in debentures, common stock or other instruments (i.e., “in kind” rather than in cash). The type of instrument in which interest may or will be paid would be known by the Portfolio at the time of investment. While PIKs generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Portfolio to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by the Code.

Unlike PIKs, delayed interest securities do not pay interest for a specified period. Because values of securities of this type are subject to greater fluctuations than are the values of securities that distribute income regularly, they may be more speculative than such securities.

Short-Term Investments

The Prospectus discusses briefly the ability of the Portfolio to invest a portion of its assets in federally tax-exempt or taxable short-term securities or shares of money market funds (“short-term investments”). The Portfolio will invest only in taxable short-term investments that are either (i) U.S. government

S-18

securities, (ii) rated within the highest grade by Moody’s, Standard & Poor’s or Fitch and mature within one year from the date of purchase or carry a variable or floating rate of interest or (iii) taxable money market funds. See Appendix A for more information about ratings by Moody’s, Standard & Poor’s, and Fitch.

Tax-Exempt Short-Term Investments

The federally tax-exempt short-term investments the Portfolio may invest in include, but are not limited to, the following:

BANs are usually general obligations of state and local governmental issuers, which are sold to obtain interim financing for projects that will eventually be funded through the sale of long-term debt obligations or bonds. The ability of an issuer to meet its obligations on its BANs is primarily dependent on the issuer’s access to the long-term municipal bond market and the likelihood that the proceeds of such bond sales will be used to pay the principal and interest on the BANs.

TANs are issued by state and local governments to finance the current operations of such governments. Repayment is generally to be derived from specific future tax revenues. Tax anticipation notes are usually general obligations of the issuer. A weakness in an issuer’s capacity to raise taxes due to, among other things, a decline in its tax base or a rise in delinquencies, could adversely affect the issuer’s ability to meet its obligations on outstanding TANs.

RANs are issued by governments or governmental bodies with the expectation that future revenues from a designated source will be used to repay the notes. In general, they also constitute general obligations of the issuer. A decline in the receipt of projected revenues, such as anticipated revenues from another level of government, could adversely affect an issuer’s ability to meet its obligations on outstanding RANs. In addition, the possibility that the revenues would, when received, be used to meet other obligations could affect the ability of the issuer to pay the principal and interest on RANs.

Construction Loan Notes are issued to provide construction financing for specific projects. Frequently, these notes are redeemed with funds obtained from the Federal Housing Administration.

Bank Notes are notes issued by local government bodies and agencies as those described above to commercial banks as evidence of borrowings. The purposes for which the notes are issued are varied, but they are frequently issued to meet short-term working capital or capital-project needs. These notes may have risks similar to the risks associated with TANs and RANs.

Tax-Exempt Commercial Paper (Municipal Paper) represents very short-term unsecured, negotiable promissory notes, issued by states, municipalities and their agencies. Payment of principal and interest on issues of municipal paper may be made from various sources, to the extent the funds are available therefrom. Maturities of municipal paper generally will be shorter than the maturities of TANs, BANs or RANs. There is a limited secondary market for issues of municipal paper.

Certain municipal obligations may carry variable or floating rates of interest whereby the rate of interest is not fixed, but varies with changes in specified market rates or indices, such as a bank prime rate or a tax-exempt money market index.

While these various types of notes as a group represent the major portion of the tax-exempt note market, other types of notes are occasionally available in the marketplace and the Portfolio may invest in such other types of notes to the extent permitted under its investment objectives, policies and limitations. Such notes may be issued for different purposes and may be secured differently from those mentioned above.

Municipal Money Market Funds that pay interest income exempt from regular federal and, in some cases, state and local income taxes. The Portfolio will bear its proportionate share of the money market fund’s fees and expenses.

Taxable Short-Term Investments

The Portfolio may also invest in the following taxable short-term investments. Interest on each such instrument is taxable for federal income tax purposes and would reduce the amount of tax-free interest payable to shareholders.

Taxable short-term investments the Portfolio may invest in include but are not limited to:

Certificates of Deposit (CDs)—A certificate of deposit is a negotiable interest bearing instrument with a specific maturity. CDs are issued by banks in exchange for the deposit of funds and normally

S-19

can be traded in the secondary market, prior to maturity. The Portfolio will only invest in U.S. dollar denominated CDs issued by U.S. banks with assets of $1 billion or more.

Commercial Paper—Commercial paper is the term used to designate unsecured short-term promissory notes issued by corporations. Maturities on these issues vary from a few days to nine months. Commercial paper may be purchased from U.S. corporations.

Taxable Money Market Funds—These funds pay interest income that is taxable on the federal and state levels. The Portfolio will bear its proportionate share of the money market fund’s fees and expenses.

U.S. Government Direct Obligations are issued by the United States Treasury and include bills, notes and bonds.

—Treasury bills are issued with maturities of up to one year. They are issued in bearer form, are sold on a discount basis and are payable at par value at maturity.

—Treasury notes are longer-term interest bearing obligations with original maturities of one to seven years.

—Treasury bonds are longer-term interest-bearing obligations with original maturities from five to thirty years.

U.S. Government Agencies Securities—Certain federal agencies have been established as instrumentalities of the U.S. government to supervise and finance certain types of activities. These agencies include, but are not limited to, the Bank for Cooperatives, Federal Land Banks, Federal Intermediate Credit Banks, Federal Home Loan Banks, Federal National Mortgage Association, Government National Mortgage Association, Export-Import Bank of the United States, and Tennessee Valley Authority. Issues of these agencies, while not direct obligations of the U.S. government, are either backed by the full faith and credit of the United States or are guaranteed by the Treasury or supported by the issuing agencies’ right to borrow from the Treasury. There can be no assurance that the U.S. government itself will pay interest and principal on securities as to which it is not legally so obligated.

Other Corporate Obligations—The Portfolio may purchase notes, bonds and debentures issued by corporations if at the time of purchase there is less than one year remaining until maturity or if they carry a variable or floating rate of interest.

Repurchase Agreements—The Portfolio may invest temporarily up to 5% of its assets in repurchase agreements, which are agreements pursuant to which securities are acquired by the Portfolio from a third party with the understanding that they will be repurchased by the seller at a fixed price on an agreed date. These agreements may be made with respect to any of the portfolio securities in which the Portfolio is authorized to invest. Repurchase agreements may be characterized as loans secured by the underlying securities. The Portfolio may enter into repurchase agreements with (i) member banks of the Federal Reserve System having total assets in excess of $500 million and (ii) securities dealers, provided that such banks or dealers meet the creditworthiness standards established by the Portfolio’s Board of Trustees (“Qualified Institutions”). Nuveen Asset Management will monitor the continued creditworthiness of Qualified Institutions, subject to the oversight of the Portfolio’s Board of Trustees.

The use of repurchase agreements involves certain risks. For example, if the seller of securities under a repurchase agreement defaults on its obligation to repurchase the underlying securities, as a result of its bankruptcy or otherwise, the Portfolio will seek to dispose of such securities, which action could involve costs or delays. If the seller becomes insolvent and subject to liquidation or reorganization under applicable bankruptcy or other laws, the Portfolio’s ability to dispose of the underlying securities may be restricted. Finally, it is possible that the Portfolio may not be able to substantiate its interest in the underlying securities. To minimize this risk, the securities underlying the repurchase agreement will be held by the custodian at all times in an amount at least equal to the repurchase price, including accrued interest. If the seller fails to repurchase the securities, the Portfolio may suffer a loss to the extent proceeds from the sale of the underlying securities are less than the repurchase price.

The resale price reflects the purchase price plus an agreed upon market rate of interest that is unrelated to the coupon rate or date of maturity of the purchased security. The collateral is marked to market daily. Such agreements permit the Portfolio to keep all its assets earning interest while retaining “overnight” flexibility in pursuit of investments of a longer-term nature.

S-20

Standby Commitments

The Portfolio may obtain standby commitments when it purchases municipal obligations. A standby commitment gives the holder the right to sell the underlying security to the seller at an agreed-upon price on certain dates or within a specified period. The Portfolio will acquire standby commitments solely to facilitate portfolio liquidity and not with a view to exercising them at a time when the exercise price may exceed the current value of the underlying securities. If the exercise price of a standby commitment held by the Portfolio should exceed the current value of the underlying securities, the Portfolio may refrain from exercising the standby commitment in order to avoid causing the issuer of the standby commitment to sustain a loss and thereby jeopardizing the Portfolio’s business relationship with the issuer. The Portfolio will enter into standby commitments only with banks and securities dealers that, in the opinion of Nuveen Asset Management, present minimal credit risks. However, if a securities dealer or bank is unable to meet its obligation to repurchase the security when the Portfolio exercises a standby commitment, the Portfolio might be unable to recover all or a portion of any loss sustained from having to sell the security elsewhere. Standby commitments will be valued at zero in determining the Portfolio’s net asset value.

Structured Notes

The Portfolio may invest in structured notes, including “total rate of return swaps” with rates of return determined by reference to the total rate of return on one or more loans referenced in such notes. The rate of return on a structured note may be determined by applying a multiplier to the rate of total return on the referenced loan or loans. Application of a multiplier is comparable to the use of leverage which magnifies the potential for gain and the risk of loss because a relatively small decline in the value of a referenced note could result in a relatively large loss in the value of the structured note.

Variable, Floating, and Fixed Rate Debt Obligations

The debt obligations in which the Portfolio invests may have variable, floating, or fixed interest rates. Variable rate securities provide for periodic adjustments in the interest rate. Floating rate securities are generally offered at an initial interest rate which is at or above prevailing market rates. The interest rate paid on floating rate securities is then reset periodically (commonly every 90 days) to an increment over some predetermined interest rate index. Commonly utilized indices include the three-month Treasury bill rate, the 180-day Treasury bill rate, the one-month or three-month London Interbank Offered Rate (LIBOR), the prime rate of a bank, the commercial paper rates, or the longer-term rates on U.S. Treasury securities. Variable and floating rate securities are relatively long-term instruments that often carry demand features permitting the holder to demand payment of principal at any time or at specified intervals prior to maturity plus accrued interest. In order to most effectively use these securities, the Sub-Adviser must correctly assess probable movements in interest rates. If the Sub-Adviser incorrectly forecasts such movements, the Portfolio could be adversely affected by use of variable and floating rate securities.

S-21

Fixed rate securities pay a fixed rate of interest and tend to exhibit more price volatility during times of rising or falling interest rates than securities with variable or floating rates of interest. The value of fixed rate securities will tend to fall when interest rates rise and rise when interest rates fall. The value of variable or floating rate securities, on the other hand, fluctuates much less in response to market interest rate movements than the value of fixed rate securities. This is because variable and floating rate securities behave like short-term instruments in that the rate of interest they pay is subject to periodic adjustments according to a specified formula, usually with reference to some interest rate index or market interest rate. Fixed rate securities with short-term characteristics are not subject to the same price volatility as fixed rate securities without such characteristics. Therefore, they behave more like variable or floating rate securities with respect to price volatility.

When-Issued and Delayed-Delivery Securities

The Portfolio may purchase and sell municipal obligations on a when-issued or delayed-delivery basis. When-issued and delayed-delivery transactions arise when securities are purchased or sold with payment and delivery beyond the regular settlement date. (When-issued transactions normally settle within 15-45 days.) On such transactions the payment obligation and the interest rate are fixed at the time the buyer enters into the commitment. The commitment to purchase securities on a when-issued or delayed-delivery basis may involve an element of risk because the value of the securities is subject to market fluctuation, no interest accrues to the purchaser prior to settlement of the transaction, and at the time of delivery the market value may be less than cost. At the time the Portfolio makes the commitment to purchase a municipal obligation on a when-issued or delayed-delivery basis, it will record the transaction and reflect the amount due and the value of the security in determining its net asset value. Likewise, at the time the Portfolio makes the commitment to sell a municipal obligation on a delayed-delivery basis, it will record the transaction and include the proceeds to be received in determining its net asset value; accordingly, any fluctuations in the value of the municipal obligation sold pursuant to a delayed-delivery commitment are ignored in calculating net asset value so long as the commitment remains in effect. The Portfolio will maintain designated readily marketable assets at least equal in value to commitments to purchase when-issued or delayed-delivery securities, such assets to be designated or segregated by the custodian specifically for the settlement of such commitments, if necessary. The Portfolio will only make commitments to purchase municipal obligations on a when-issued or delayed-delivery basis with the intention of actually acquiring the securities, but the Portfolio reserves the right to sell these securities before the settlement date if it is deemed advisable. If a when-issued security is sold before delivery any gain or loss would not be tax-exempt. The Portfolio commonly engages in when-issued transactions in order to purchase or sell newly-issued municipal obligations, and may engage in delayed-delivery transactions in order to manage its operations more effectively.

The Portfolio may buy when-issued and delayed-delivery securities that settle more than 60 days after purchase. These transactions are called “forwards.” Municipal forwards pay higher interest after settlement than standard bonds, to compensate the buyer for bearing market risk and deferring income during the settlement period, and can often be bought at attractive prices and yields. If the Portfolio knows that a portfolio bond will, or is likely to, be called or mature on a specific future date, the Portfolio may buy forwards settling on or about that date to replace the called or maturing bond and “lock in” a currently attractive interest rate. The Portfolio also may invest up to 15% of its assets in forwards that do not serve to replace a specific portfolio bond.

Zero Coupon and Step Coupon Securities

The Portfolio may invest in zero coupon and step coupon securities. Zero coupon securities pay no cash income to their holders until they mature. When held to maturity, their entire return comes from the difference between their purchase price and their maturity value. Step coupon securities are debt securities that may not pay interest for a specified period of time and then, after the initial period, may pay interest at a series of different rates. Both zero coupon and step coupon securities are issued at substantial discounts from their value at maturity. Because interest on these securities is not paid on a current basis, the values of securities of this type are subject to greater fluctuations than are the value of securities that distribute income regularly and may be more speculative than such securities. Accordingly, the values of these securities may be highly volatile as interest rates rise or fall. In addition, while such securities generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Portfolio to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by the Code.

Board Leadership Structure and Risk Oversight

S-30

The Board believes the unitary board structure enhances good and effective governance, particularly given the nature of the structure of the investment company complex. Funds in the same complex generally are served by the same service providers and personnel and are governed by the same regulatory scheme which raises common issues that must be addressed by the trustees across the fund complex (such as compliance, valuation, liquidity, brokerage, trade allocation or risk management). The Board believes it is more efficient to have a single board review and oversee common policies and procedures which increases the Board’s knowledge and expertise with respect to the many aspects of fund operations that are complex-wide in nature. The unitary structure also enhances the Board’s influence and oversight over the investment adviser and other service providers.

In an effort to enhance the independence of the Board, the Board also has a Chair that is an independent trustee. The Board recognizes that a chair can perform an important role in setting the agenda for the Board, establishing the boardroom culture, establishing a point person on behalf of the Board for fund management, and reinforcing the Board’s focus on the long-term interests of shareholders. The Board recognizes that a chair may be able to better perform these functions without any conflicts of interests arising from a position with fund management. Accordingly, the trustees have elected Mr. Toth to serve as the independent Chair of the Board. Specific responsibilities of the Chair include: (i) presiding at all meetings of the Board and of the shareholders; (ii) seeing that all orders and resolutions of the trustees are carried into effect; and (iii) maintaining records of and, whenever necessary, certifying all proceedings of the trustees and the shareholders.

Although the Board has direct responsibility over various matters (such as advisory contracts, underwriting contracts and fund performance), the Board also exercises certain of its oversight responsibilities through several committees that it has established and which report back to the full Board. The Board believes that a committee structure is an effective means to permit trustees to focus on particular operations or issues affecting the Nuveen Funds, including risk oversight. More specifically, with respect to risk oversight, the Board has delegated matters relating to valuation and compliance to certain committees (as summarized below) as well as certain aspects of investment risk. In addition, the Board believes that the periodic rotation of trustees among the different committees allows the trustees to gain additional and different perspectives of a Nuveen Fund’s operations. The Board has established six standing committees: the Executive Committee, the Dividend Committee, the Audit Committee, the Compliance, Risk Management and Regulatory Oversight Committee, the Nominating and Governance Committee and the Open-End Funds Committee. The Board may also from time to time create ad hoc committees to focus on particular issues as the need arises. The membership and functions of the standing committees are summarized below.

The Audit Committee assists the Board in the oversight and monitoring of the accounting and reporting policies, processes and practices of the Nuveen Funds, and the audits of the financial statements of the Nuveen Funds; the quality and integrity of the financial statements of the Nuveen Funds; the Nuveen Funds’ compliance with legal and regulatory requirements relating to the Nuveen Funds’ financial statements; the independent auditors’ qualifications, performance and independence;

S-31

and the pricing procedures of the Nuveen Funds and the Adviser’s internal valuation group. It is the responsibility of the Audit Committee to select, evaluate and replace any independent auditors (subject only to Board and, if applicable, shareholder ratification) and to determine their compensation. The Audit Committee is also responsible for, among other things, overseeing the valuation of securities comprising the Nuveen Funds’ portfolios. Subject to the Board’s general supervision of such actions, the Audit Committee addresses any valuation issues, oversees the Nuveen Funds’ pricing procedures and actions taken by the Adviser’s internal valuation group which provides regular reports to the committee, reviews any issues relating to the valuation of the Nuveen Funds’ securities brought to its attention and considers the risks to the Nuveen Funds in assessing the possible resolutions to these matters. The Audit Committee may also consider any financial risk exposures for the Nuveen Funds in conjunction with performing its functions.

The Nominating and Governance Committee is responsible for seeking, identifying and recommending to the Board qualified candidates for election or appointment to the Board. In addition, the Nominating and Governance Committee oversees matters of corporate governance, including the evaluation of Board performance and processes, the assignment and rotation of committee members, and the establishment of corporate governance guidelines and procedures, to the extent necessary or desirable, and matters related thereto. Although the unitary and committee structure has been developed over the years and the Nominating and Governance Committee believes the structure has provided efficient and effective governance, the committee recognizes that as demands on the Board evolve over time (such as through an increase in the number of funds overseen or an increase in the complexity of the issues raised), the committee must continue to evaluate the Board and committee structures and their processes and modify the foregoing as may be necessary or appropriate to continue to provide effective governance. Accordingly, the Nominating and Governance Committee has a separate meeting each year to, among other things, review the Board and committee structures, their performance and functions, and recommend any modifications thereto or alternative structures or processes that would enhance the Board’s governance of the Nuveen Funds.

S-32

The Compliance, Risk Management and Regulatory Oversight Committee (the “Compliance Committee”) is responsible for the oversight of compliance issues, risk management and other regulatory matters affecting the Nuveen Funds that are not otherwise the jurisdiction of the other committees. The Board has adopted and periodically reviews policies and procedures designed to address the Nuveen Funds’ compliance and risk matters. As part of its duties, the Compliance Committee reviews the policies and procedures relating to compliance matters and recommends modifications thereto as necessary or appropriate to the full Board; develops new policies and procedures as new regulatory matters affecting the Nuveen Funds arise from time to time; evaluates or considers any comments or reports from examinations from regulatory authorities and responses thereto; and performs any special reviews, investigations or other oversight responsibilities relating to risk management, compliance and/or regulatory matters as requested by the Board.

Board Diversification and Trustee Qualifications

In determining that a particular trustee was qualified to serve on the Board, the Board has considered each trustee’s background, skills, experience and other attributes in light of the composition of the Board with no particular factor controlling. The Board believes that trustees need to have the ability to critically

S-33

review, evaluate, question and discuss information provided to them, and to interact effectively with Fund management, service providers and counsel, in order to exercise effective business judgment in the performance of their duties, and the Board believes each trustee satisfies this standard. An effective trustee may achieve this ability through his or her educational background; business, professional training or practice; public service or academic positions; experience from service as a board member or executive of investment funds, public companies or significant private or not-for-profit entities or other organizations; and/or other life experiences. Accordingly, set forth below is a summary of the experiences, qualifications, attributes, and skills that led to the conclusion, as of the date of this document, that each trustee should continue to serve in that capacity. References to the experiences, qualifications, attributes and skills of trustees are pursuant to requirements of the SEC, do not constitute holding out of the Board or any trustee as having any special expertise or experience and shall not impose any greater responsibility or liability on any such person or on the Board by reason thereof.

Board Compensation

S-37

S-38

The Trust does not have a retirement or pension plan. The Trust is a participant in a deferred compensation plan (the “Deferred Compensation Plan”) that permits any independent trustee to elect to defer receipt of all or a portion of his or her compensation as an independent trustee. The deferred compensation of a participating trustee is credited to a book reserve account of the participating Nuveen Funds when the compensation would otherwise have been paid to the trustee. The value of the trustee’s deferral account at any time is equal to the value that the account would have had if contributions to the account had been invested and reinvested in shares of one or more of the eligible Nuveen Funds. An independent trustee may elect to receive distributions in a lump sum or over a period of five years. No participating Nuveen Fund will be liable for any other fund’s obligations to make distributions under the Deferred Compensation Plan.

The Portfolio has no employees. Each officer of the Trust serves without any compensation from the Portfolio. The CCO’s compensation, which is composed of base salary and incentive compensation, is paid by the Adviser, with review and input by the Board. The Portfolio reimburses the Adviser for an allocable portion of the Adviser’s cost of the CCO’s incentive compensation.

SERVICE PROVIDERS

Investment Adviser

Nuveen Fund Advisors, located at 333 West Wacker Drive, Chicago, Illinois 60606, serves as the investment adviser of the Portfolio, with responsibility for the overall management of the Portfolio. The Adviser is also responsible for managing the Portfolio’s business affairs and providing day-to-day administrative services to the Portfolio. The Adviser has selected its affiliate, Nuveen Asset Management, located at 333 West Wacker Drive, Chicago, Illinois 60606, to serve as sub-adviser to manage the investment portfolio of the Portfolio. For additional information regarding the management services performed by the Adviser and the Sub-Adviser, see “Who Manages the Portfolio” in the Prospectus.

The Adviser is an affiliate of the Distributor, which is located at 333 West Wacker Drive, Chicago, Illinois 60606. The Distributor is the principal underwriter for the Nuveen Mutual Funds, and has served as co-managing underwriter for the shares of the Nuveen Closed-End Funds. The Adviser and the Distributor are subsidiaries of Nuveen, LLC, the investment management arm of TIAA.

The Portfolio’s investment management agreement with the Adviser does not require the Portfolio to pay any management or other fees. Although the Portfolio does not compensate the Adviser directly for its services under the investment management agreement, the Adviser may benefit from its relationship with the sponsors of separately managed account programs in which the Portfolio is an investment option.

Sub-Adviser

The Adviser has selected its affiliate, Nuveen Asset Management, to serve as sub-adviser to manage the investment portfolio of the Portfolio.

S-40

Portfolio Manager

Martin J. Doyle has primary responsibility for the day-to-day implementation of the investment strategies of the Portfolio.

Compensation

Portfolio managers are compensated through a combination of base salary and variable components consisting of (i) a cash bonus; (ii) a long-term performance award; and (iii) participation in a profits interest plan.

Base salary. A portfolio manager’s base salary is determined based upon an analysis of the portfolio manager’s general performance, experience and market levels of base pay for such position.

Cash bonus. A portfolio manager is eligible to receive an annual cash bonus that is based on three variables: risk-adjusted investment performance relative to benchmark generally measured over the most recent one, three and five year periods (unless the portfolio manager’s tenure is shorter), ranking versus Morningstar peer funds generally measured over the most recent one, three and five year periods (unless the portfolio manager’s tenure is shorter), and management and peer reviews.

Long-term performance award. A portfolio manager is eligible to receive a long-term performance award that vests after three years. The amount of the award when granted is based on the same factors used in determining the cash bonus. The value of the award at the completion of the three-year vesting period is adjusted based on the risk-adjusted investment performance of Portfolio(s) managed by the portfolio manager during the vesting period and the performance of the TIAA organization as a whole.

Profits interest plan. Portfolio managers are eligible to receive profits interests in Nuveen Asset Management and its affiliate, TAL, which vest over time and entitle their holders to a percentage of the firms’ annual profits. Profits interests are allocated to each portfolio manager based on such person’s overall contribution to the firms.

There are generally no differences between the methods used to determine compensation with respect to the Portfolio and the Other Accounts shown in the table below.

Other Accounts Managed

Conflicts of Interest

Actual or apparent conflicts of interest may arise when a portfolio manager has day-to-day management responsibilities with respect to more than one account. More specifically, portfolio managers who manage multiple accounts are presented a number of potential conflicts, including, among others, those discussed below.

The management of multiple accounts may result in a portfolio manager devoting unequal time and attention to the management of each account. Nuveen Asset Management seeks to manage such competing interests for the time and attention of portfolio managers by having portfolio managers focus on a particular investment discipline. Most accounts managed by a portfolio manager in a particular investment strategy are managed using the same investment models.

If a portfolio manager identifies a limited investment opportunity which may be suitable for more than one account, an account may not be able to take full advantage of that opportunity due to an allocation of filled purchase or sale orders across all eligible accounts. To deal with these situations, Nuveen Asset Management has adopted procedures for allocating limited opportunities across multiple accounts.

With respect to many of its clients’ accounts, Nuveen Asset Management determines which broker to use to execute transaction orders, consistent with its duty to seek best execution of the transaction. However, with respect to certain other accounts, Nuveen Asset Management may be limited by the client with respect to the selection of brokers or may be instructed to direct trades through a particular broker. In these cases, Nuveen Asset Management may place separate, non-simultaneous, transactions for the

S-41

Portfolio and other accounts which may temporarily affect the market price of the security or the execution of the transaction, or both, to the detriment of the Portfolio or the other accounts.

Some clients are subject to different regulations. As a consequence of this difference in regulatory requirements, some clients may not be permitted to engage in all the investment techniques or transactions or to engage in these transactions to the same extent as the other accounts managed by a portfolio manager. Finally, the appearance of a conflict of interest may arise where Nuveen Asset Management has an incentive, such as a performance-based management fee, which relates to the management of some accounts, with respect to which a portfolio manager has day-to-day management responsibilities.

Conflicts of interest may also arise when the Sub-Adviser invests one or more of its client accounts in different or multiple parts of the same issuer’s capital structure, including investments in public versus private securities, debt versus equity, or senior versus junior/subordinated debt, or otherwise where there are different or inconsistent rights or benefits. Decisions or actions such as investing, trading, proxy voting, exercising, waiving or amending rights or covenants, workout activity, or serving on a board, committee or other involvement in governance may result in conflicts of interest between clients holding different securities or investments. Generally, individual portfolio managers will seek to act in a manner that they believe serves the best interest of the accounts they manage. In cases where a portfolio manager or team faces a conflict among its client accounts, it will seek to act in a manner that it believes best reflects its overall fiduciary duty, which may result in relative advantages or disadvantages for particular accounts.

Nuveen Asset Management has adopted certain compliance procedures which are designed to address these types of conflicts common among investment managers. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.

CODES OF ETHICS

The Portfolio, the Adviser, Nuveen Asset Management and the Distributor have adopted codes of ethics pursuant to Rule 17j-1 under the 1940 Act and with respect to the Adviser and the Sub-Adviser, Rule 204A-1 under the Investment Advisers Act of 1940, as amended (the "Advisers Act"), addressing personal securities transactions and other conduct by investment personnel and access persons who may have access to information about the Portfolio's securities transactions. The codes are intended to address potential conflicts of interest that can arise in connection with personal trading activities of such persons. Persons subject to the codes are generally permitted to engage in personal securities transactions, including investing in securities eligible for investment by the Portfolio, subject to certain prohibitions, which may include prohibitions on investing in certain types of securities, pre-clearance requirements, blackout periods, annual and quarterly reporting of personal securities holdings and limitations on personal trading of initial public offerings. Violations of the codes are subject to review by the Board of Trustees and could result in severe penalties.

PROXY VOTING POLICIES

The Portfolio invests its assets primarily in municipal bonds and cash management securities. On rare occasions the Portfolio may acquire, directly or through a special purpose vehicle, equity securities of a municipal bond issuer whose bonds the Portfolio already owns when such bonds have deteriorated or are expected shortly to deteriorate significantly in credit quality. The purpose of acquiring equity securities generally will be to acquire control of the municipal bond issuer and to seek to prevent the credit deterioration or facilitate the liquidation or other workout of the distressed issuer’s credit problem. In the course of exercising control of a distressed municipal issuer, Nuveen Asset Management may pursue the Portfolio’s interests in a variety of ways, which may entail negotiating and executing consents, agreements and other arrangements, and otherwise influencing the management of the issuer. Nuveen Asset Management does not consider such activities proxy voting for purposes of Rule 206(4)-6 under the 1940 Act, but nevertheless provides reports to the Portfolio’s Board of Trustees on its control activities on a quarterly basis.

In the rare event that a municipal issuer were to issue a proxy or that the Portfolio were to receive a proxy issued by a cash management security, Nuveen Asset Management would either engage an independent third party to determine how the proxy should be voted or vote the proxy with the consent, or based on the instructions, of the Portfolio’s Board of Trustees or its representative. A member of Nuveen Asset Management’s legal department would oversee the administration of the voting, and ensure that records were maintained in accordance with Rule 206(4)-6 under the Advisers Act, reports were filed with the SEC on Form N-PX, and the results provided to the Portfolio’s Board of Trustees and made available to shareholders as required by applicable rules.

Information regarding how the Portfolio voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available without charge by accessing Nuveen’s website at http://www.nuveen.com or the SEC’s website at http://www.sec.gov.

PORTFOLIO TRANSACTIONS

Nuveen Asset Management is responsible for decisions to buy and sell securities for the Portfolio, the negotiation of the prices to be paid or received for principal trades, and the allocation of its transactions among various dealer firms. Portfolio securities will normally be purchased directly from an underwriter in a new issue offering or in the over-the-counter secondary market from the principal dealers in such securities, unless it appears that a better price or execution may be obtained elsewhere.

On behalf of the Portfolio, Nuveen Asset Management may seek to buy from or sell securities to another fund or account advised by Nuveen Asset Management or an affiliate. Nuveen Asset Management may effect purchases and sales between its clients or clients of its affiliates, including the Portfolio (referred to herein as “cross trades”), if it believes that such transactions are appropriate based on each party’s investment objectives and guidelines, subject to applicable law and regulation. Cross trades may give rise to potential conflicts of interest for Nuveen Asset Management. On any occasion

S-43

when the Portfolio participates in a cross trade, the Portfolio will comply with procedures adopted pursuant to Rule 17a-7 under the 1940 Act and applicable SEC guidance.

The Portfolio expects that substantially all portfolio transactions will be effected on a principal (as opposed to an agency) basis and, accordingly, does not expect to pay significant amounts of brokerage commissions. Brokerage will not be allocated based on the sale of the Portfolio’s shares. Purchases from underwriters will include a commission or concession paid by the issuer to the underwriter, and purchases from dealers will include the spread between the bid and asked price. It is the policy of Nuveen Asset Management to seek the best execution under the circumstances of each trade. Nuveen Asset Management evaluates price as the primary consideration, with the financial condition, reputation and responsiveness of the dealer considered secondarily in determining best execution. Given the best execution obtainable, it may be Nuveen Asset Management’s practice to select dealers that, in addition, furnish research information (primarily credit analyses of issuers and general economic reports) and statistical and other services to Nuveen Asset Management. It is not possible to place a dollar value on information and statistical and other services received from dealers. Since it is only supplementary to Nuveen Asset Management’s own research efforts, the receipt of research information is not expected to reduce significantly Nuveen Asset Management’s expenses. For certain secondary market transactions where the execution capability of two brokers is judged to be of substantially similar quality, Nuveen Asset Management may randomly select one of them. While Nuveen Asset Management will be primarily responsible for the placement of the portfolio transactions of the Portfolio, the policies and practices of Nuveen Asset Management in this regard must be consistent with the foregoing and will, at all times, be subject to review by the Board of Trustees.

Nuveen Asset Management may manage other investment companies and investment accounts for other clients that have investment objectives similar to the Portfolio. Subject to applicable laws and regulations, Nuveen Asset Management seeks to allocate portfolio transactions equitably whenever concurrent decisions are made to purchase or sell securities by the Portfolio and another advisory account. In making such allocations the main factors to be considered will be the respective investment objectives, the relative size of the portfolio holdings of the same or comparable securities, the availability of cash for investment or need to raise cash, and the size of investment commitments generally held. While this procedure could have a detrimental effect on the price or amount of the securities (or, in the case of dispositions, the demand for securities) available to the Portfolio from time to time, it is the opinion of the Board of Trustees that the benefits available from the Nuveen Asset Management organization will outweigh any disadvantage that may arise from exposure to simultaneous transactions.

The Portfolio has paid no brokerage commissions in the past three fiscal years.

DISCLOSURE OF PORTFOLIO HOLDINGS

The Nuveen Mutual Funds have adopted a portfolio holdings disclosure policy which governs the dissemination of the Portfolio’s holdings. In accordance with this policy, the Portfolio may provide portfolio holdings information to third parties no earlier than the time a report is filed with the SEC that is required to contain such information or one day after the information is posted on the publicly accessible website www.nuveen.com/resource-center. A complete list of portfolio holdings information is generally made available on this website as of the end of each month, approximately two to five business days after the end of the month for which the information is current. This information will remain available on the website at least until the Portfolio files with the SEC its Form N-CSR or Form N-PORT for the period that includes the date as of which the website information is current.

Additionally, the Portfolio may disclose portfolio holdings information that has not been included in a filing with the SEC or posted on the Portfolio’s website (i.e., non-public portfolio holdings information) only if there is a legitimate business purpose for doing so and if the recipient is required, either by explicit agreement or by virtue of the recipient’s duties to the Portfolio as an agent or service provider, to maintain the confidentiality of the information and to not use the information in an improper manner (e.g., personal trading). In this context, portfolio holdings information does not include summary information from which the identity of the Portfolio’s specific portfolio holdings cannot reasonably be derived. The Portfolio may

S-44

disclose on an ongoing basis non-public portfolio holdings information in the normal course of its investment and administrative operations to various service providers, including the Adviser and/or Sub-Adviser, independent registered public accounting firm, custodian, financial printer, proxy voting service(s), and to the legal counsel for the Portfolio’s independent trustees. Also, the Adviser may transmit to service providers non-public portfolio holdings information to enable the Adviser to perform portfolio attribution analysis using third-party systems and software programs. The Adviser and/or Sub-Adviser may also provide certain portfolio holdings information to broker-dealers from time to time in connection with the purchase or sale of securities or requests for price quotations or bids on one or more securities. In providing this information, reasonable precautions are taken in an effort to avoid potential misuse of the disclosed information, including limitations on the scope of the portfolio holdings information disclosed, when appropriate. The Portfolio, the Adviser, and the Sub-Adviser do not receive compensation or other consideration in exchange for the disclosure of portfolio holdings.

Non-public portfolio holdings information may be provided to other persons if approved by the Portfolio’s Chief Administrative Officer or Secretary upon a determination that there is a legitimate business purpose for doing so, the disclosure is consistent with the interests of the Portfolio, and the recipient is obligated to maintain the confidentiality of the information and not misuse it, which includes a prohibition on trading on such non-public information.

Compliance officers of the Portfolio and the Adviser and Sub-Adviser periodically monitor overall compliance with the policy to ascertain whether portfolio holdings information is disclosed in a manner that is consistent with the Portfolio’s policy. Reports are made to the Portfolio’s Board of Trustees on an annual basis.

There is no assurance that the Portfolio’s policies on portfolio holdings information will protect the Portfolio from the potential misuse of portfolio holdings information by individuals or firms in possession of such information.

The following parties currently receive non-public portfolio holdings information regarding one or more of the Nuveen Mutual Funds on an ongoing basis pursuant to the various arrangements described above:

S-45

NET ASSET VALUE

The Portfolio’s net asset value is determined as set forth in the Prospectus under “General Information—Net Asset Value.”

SHARES OF BENEFICIAL INTEREST

The Board of Trustees of the Trust is authorized to issue an unlimited number of shares in one or more series, which may be divided into classes of shares. Each currently authorized and outstanding series consists of one class of shares. The Board of Trustees of the Trust has the right to establish additional series and classes of shares in the future, to change those series or classes and to determine the preferences, voting powers, rights and privileges thereof.

The Trust is not required and does not intend to hold annual meetings of shareholders. Shareholders owning more than 10% of the outstanding shares of the Portfolio have the right to call a special meeting to remove trustees or for any other purpose.

Under Massachusetts law applicable to Massachusetts business trusts, shareholders of such a trust may, under certain circumstances, be held personally liable as partners for its obligations. However, the Declaration of Trust of the Trust contains an express disclaimer of shareholder liability for acts or obligations of the Trust and requires that notice of this disclaimer be given in each agreement, obligation or instrument entered into or executed by the Trust or the trustees. The Trust’s Declaration of Trust further provides for indemnification out of the assets and property of the Trust for all losses and expenses of any shareholder held personally liable for the obligations of the Trust. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which both inadequate insurance existed and the Trust or the Portfolio itself was unable to meet its obligations. The Trust believes the likelihood of the occurrence of these circumstances is remote.

TAX MATTERS

Federal Income Tax Matters

This section summarizes some of the main U.S. federal income tax consequences of owning shares of the Portfolio. Tax laws and interpretations change frequently, and this summary does not describe all of the tax consequences to all taxpayers. For example, this summary generally does not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer or other investor with special circumstances. In addition, this section does not describe your state, local or non-U.S. tax consequences. This federal income tax summary is based in part on the advice of counsel to the Portfolio. The Internal Revenue Service could disagree with any conclusions set forth in this section. In addition, Portfolio's counsel was not asked to review, and has not reached a conclusion with respect to the federal income tax treatment of the assets to be deposited in the Portfolio. Consequently, this summary may not be sufficient for you to use for the purpose of avoiding penalties under federal tax law. As with any investment, you should seek advice based on your individual circumstances from your own tax professional.

Portfolio Status

The Portfolio intends to qualify as a “regulated investment company” under the federal tax laws. If the Portfolio qualifies as a regulated investment company and distributes its income as required by the tax law, the Portfolio generally will not pay federal income taxes. If the Portfolio fails for any taxable year to qualify as a regulated investment company for federal income tax purposes, the Portfolio itself will generally be subject to federal income taxation (which will reduce the amount of Portfolio income available for distribution) and your tax consequences will be different from those described in this section (for example, all distributions to you will generally be taxed as ordinary income, even if those distributions are derived from tax-exempt interest or capital gains realized by the Portfolio).

Qualification as a Regulated Investment Company

As a regulated investment company, the Portfolio generally will not be subject to federal income tax on the portion of its investment company taxable income (as that term is defined in the Code, but without regard to the deduction for dividends paid) and net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss), if any, that it distributes to shareholders, provided that it distributes at least 90% of its investment company taxable income and 90% of its net tax-exempt interest income for the year (the “Distribution Requirement”) and satisfies certain other requirements of the Code that are generally described below. The Portfolio also intends to make such distributions as are necessary to avoid the otherwise applicable 4% non-deductible excise tax on certain undistributed earnings.

In addition to satisfying the Distribution Requirement, the Portfolio must, among other things, derive in each taxable year at least 90% of its gross income from (1) dividends, interest, certain payments with respect to securities loans, gains from the sale or disposition of stock, securities or non-U.S. currencies and other income (including but not limited to gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and (2) net income derived from an interest in “qualified publicly traded partnerships” (as such term is defined in the Code). The Portfolio must also satisfy an asset diversification test in order to qualify as a regulated investment company. Under this test, at the close of each quarter of the Portfolio’s taxable year, (1) 50% or more of the value of the Portfolio’s assets must be represented by cash and cash items (including receivables), United States government securities, securities of other regulated investment companies, and other securities, with such other securities limited, in respect of any one issuer, to an amount not greater than 5% of the value of the Portfolio’s assets and not greater than 10% of the outstanding voting securities of such issuer and (2) not more than 25% of the value of the Portfolio’s assets may be invested in securities of (a) any one issuer (other than U.S. government securities or securities of other regulated investment companies), or of two or more issuers which the Portfolio controls and which are engaged in the same, similar or related trades or businesses or (b) in the securities of one or more “qualified publicly traded partnerships” (as such term is defined in the Code). There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis and certain corrective action is taken and certain tax payments are made by the Portfolio.

Distributions

After the end of each year, you will receive a tax statement that separates the Portfolio’s distributions into four categories, exempt-interest dividends, ordinary income distributions, capital gain dividends and returns of capital. Exempt-interest dividends generally are excluded from your gross income for federal income tax purposes. Some or all of the exempt-interest dividends, however, may be taken into account

S-47

in determining your alternative minimum tax and may have other tax consequences (e.g., they may affect the amount of your social security benefits that are taxed). Ordinary income distributions are generally taxed at your ordinary tax rate. Generally, you will treat all capital gain dividends as long-term capital gains regardless of how long you have owned your shares. To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Portfolio may make distributions that represent a return of capital for tax purposes and thus will generally not be immediately taxable to you unless the distribution exceeds your basis in your shares. The tax status of your distributions from the Portfolio is not affected by whether you reinvest your distributions in additional shares or receive them in cash. The income from the Portfolio that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year. Income from the Portfolio may also be subject to a 3.8 percent “Medicare tax.” This tax generally applies to your net investment income if your adjusted gross income exceeds certain threshold amounts, which are $250,000 in the case of married couples filing joint returns and $200,000 in the case of single individuals. Interest that is excluded from gross income and exempt-interest dividends from the Portfolio are generally not included in your net investment income for purposes of this tax.

Dividends Received Deduction

A corporation that owns shares generally will not be entitled to the dividends received deduction with respect to many dividends received from the Portfolio because the dividends received deduction is generally not available for distributions from regulated investment companies.

If You Sell or Redeem Shares

If you sell or redeem your shares, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in your shares from the amount you receive in the transaction. Your tax basis in your shares is generally equal to the cost of your shares, generally including sales charges. In some cases, however, you may have to adjust your tax basis after you purchase your shares. Further, if you hold your shares for six months or less, any loss incurred by you related to the disposition of such a share will be disallowed to the extent of the exempt-interest dividends you received, except as otherwise described in the next section.

Taxation of Capital Gains and Losses

If you are an individual, the maximum marginal stated federal tax rate for net capital gains is generally 20% (15% or 0% for taxpayers with taxable incomes below certain thresholds). Capital gains may also be subject to the “Medicare tax” described above.

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your shares to determine your holding period. If you hold a share for six months or less, any loss incurred by you related to the disposition of such share will be disallowed to the extent of the exempt-interest dividends you received, except in the case of a regular dividend paid by the Portfolio if the Portfolio declares exempt-interest dividends on a daily basis in an amount equal to at least 90 percent of its net tax-exempt interest and distributes such dividends on a monthly or more frequent basis. To the extent, if any, it is not disallowed, it will be recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Code treats certain capital gains as ordinary income in special situations.

An election may be available to you to defer recognition of the gain attributable to a capital gain dividend if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Qualification to Pay Exempt-Interest Dividends

A regulated investment company may report an applicable portion of a dividend (other than a capital gain dividend) as an “exempt-interest dividend,” if at least half of the regulated investment company’s assets at the close of each quarter of the taxable year consist of tax-exempt state and local bonds. The shareholder treats an exempt-interest dividend as an item of tax-exempt interest as described above. If the Portfolio qualifies under this test, some or all of a dividend paid by the Portfolio may be reported as an exempt-interest dividend.

S-48

In-Kind Distributions

Under certain circumstances, as described in the Prospectus, you may receive an in-kind distribution of Portfolio securities when you redeem shares or when the Portfolio terminates. This distribution will be treated as a sale for federal income tax purposes and you will generally recognize gain or loss, generally based on the value at that time of the securities and the amount of cash received. The Internal Revenue Service could, however, assert that a loss may not be currently deducted.

Exchanges

If you exchange shares of the Portfolio for shares of another Nuveen Mutual Fund, the exchange would generally be considered a sale for federal income tax purposes.

Treatment of Portfolio Expenses

You should be aware that different separately managed account program sponsors charge their own clients differing wrapped or bundled fees based, among other things, on the services being provided by the sponsor. This structure raises the question of whether the Internal Revenue Service (“IRS”) or a court might attribute these differing payment rates to the Portfolio. Such a position, if asserted, could raise issues of whether the structure produces preferential dividends and, in turn, whether the Portfolio qualifies for tax treatment as a regulated investment company. If in any year the Portfolio should fail to qualify under Subchapter M of the Code for tax treatment as a regulated investment company, the Portfolio would incur corporate federal income tax upon its income for that year. Distributions to its shareholders would be taxable dividends to the extent of the Portfolio’s current and accumulated earnings and profits (including its tax-exempt income). Such taxable dividends should qualify for the dividends received deduction for corporate shareholders and should be taxable as qualified dividend income for federal income tax purposes for individual shareholders to the extent certain holding period requirements and other requirements are satisfied. In addition, the Portfolio could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company. The Board of Trustees reserves the right not to maintain the qualification of the Portfolio as a regulated investment company if it determines such course of action to be beneficial to shareholders.

Nuveen Asset Management believes that based upon its arrangements with the various separately managed account program sponsors and the intended operation of the Portfolio, these concerns should not arise. You should be aware, however, that there is no authority on point, and that if the IRS or a court were to take a contrary position, the Portfolio’s fee arrangement could cause the dividends paid by the Portfolio not to qualify for the dividends-paid deduction because they were considered preferential dividends. In that case, the Portfolio would fail to qualify as a regulated investment company with the consequences described above.

Capital Loss Carry-Forward

PURCHASE AND REDEMPTION OF SHARES

As described in the Prospectus, the Portfolio is only available to separately managed account clients where Nuveen Fund Advisors has an agreement to serve as investment adviser or sub-adviser to the account with the separately managed account program sponsor or directly with the client.

Suspension of Right of Redemption

The Portfolio may suspend the right of redemption of shares or delay payment more than seven days (a) during any period when the New York Stock Exchange is closed (other than customary weekend and

S-49

holiday closings), (b) when trading in the markets the Portfolio normally utilizes is restricted or an emergency exists as determined by the SEC so that trading of the Portfolio’s investments or determination of its net asset value is not reasonably practicable, or (c) for any other periods that the SEC by order may permit for protection of Portfolio shareholders.

Frequent Trading Policy

Because the Portfolio is designed to be a component of a separately managed account that also invests in individual securities and other investments, its shares may be purchased or redeemed on a frequent basis for rebalancing purposes, to invest new monies, or to accommodate reductions in account size. The Portfolio is managed in a manner that is consistent with its role in the separately managed account. Because all purchase and redemption orders are initiated by Nuveen Fund Advisors, separately managed account clients are not in a position to effect purchase or redemption orders and are, therefore, unable to directly trade in shares of the Portfolio.

DISTRIBUTION

The Distributor sells shares to or through brokers, dealers, banks or other qualified financial intermediaries (collectively referred to as “Dealers”), or others, in a manner consistent with the then effective registration statement of the Trust. Pursuant to the Distribution Agreement, the Distributor, at its own expense, finances certain activities incident to the sale and distribution of the Portfolio’s shares, including printing and distributing of prospectuses and statements of additional information to other than existing shareholders, the printing and distributing of sales literature, advertising and payment of compensation and giving of concessions to Dealers. The Distributor receives for its services the excess, if any, of the sales price of the Portfolio’s shares less the net asset value of those shares, and reallows a majority or all of such amounts to the Dealers who sold the shares. The Distributor may act as a Dealer.

The Portfolio paid no underwriting commissions in the past three fiscal years.

APPENDIX A

RATINGS OF INVESTMENTS

S&P Global Ratings—A brief description of the applicable S&P Global Ratings’ (“S&P”) rating symbols and their meanings (as published by S&P) follows:

Issue Credit Ratings

An S&P Global Ratings issue credit rating is a forward-looking opinion about the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The opinion reflects S&P Global Ratings’ view of the obligor’s capacity and willingness to meet its financial commitments as they come due, and this opinion may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default.

Issue credit ratings can be either long-term or short-term. Short-term issue credit ratings are generally assigned to those obligations considered short-term in the relevant market. Short-term issue credit ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. Medium-term notes are assigned long-term ratings.

Long-Term Issue Credit Ratings*

Issue credit ratings are based, in varying degrees, on S&P Global Ratings’ analysis of the following considerations:

1. The likelihood of payment—the capacity and willingness of the obligor to meet its financial commitments on an obligation in accordance with the terms of the obligation;

2. The nature and provisions of the financial obligation, and the promise we impute; and

3. The protection afforded by, and relative position of, the financial obligation in the event of a bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors’ rights.

An issue rating is an assessment of default risk but may incorporate an assessment of relative seniority or ultimate recovery in the event of default. Junior obligations are typically rated lower than senior obligations, to reflect lower priority in bankruptcy, as noted above. (Such differentiation may apply when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.)

A-1

*Ratings from ‘AA’ to ‘CCC’ may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the rating categories.

Municipal Short-Term Note Ratings

An S&P Global Ratings U.S. municipal note rating reflects S&P Global Ratings’ opinion about the liquidity factors and market access risks unique to the notes. Notes due in three years or less will likely receive a note rating. Notes with an original maturity of more than three years will most likely receive a long-term debt rating. In determining which type of rating, if any, to assign, S&P Global Ratings’ analysis will review the following considerations:

Moody’s Investors Service, Inc.—A brief description of the applicable Moody’s Investors Service, Inc. (“Moody’s”) rating symbols and their meanings (as published by Moody’s) follows:

Ratings assigned on Moody’s global long-term and short-term rating scales are forward-looking opinions of the relative credit risks of financial obligations issued by non-financial corporates, financial institutions, structured finance vehicles, project finance vehicles, and public sector entities. Long-term ratings are assigned to issuers or obligations with an original maturity of one year or more and reflect both on the likelihood of a default or impairment on contractual financial obligations and the expected financial loss suffered in the event of default or impairment. Short-term ratings are assigned to obligations with an original maturity of thirteen months or less and reflect both on the likelihood of a default or impairment on contractual financial obligations and the expected financial loss suffered in the event of default or impairment.

A-2

Long-Term Obligation Ratings

Note: Moody’s appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category.

Medium-Term Note Program Ratings

Moody’s assigns provisional ratings to medium-term note (MTN) programs and definitive ratings to the individual debt securities issued from them (referred to as drawdowns or notes).

MTN program ratings are intended to reflect the ratings likely to be assigned to drawdowns issued from the program with the specified priority of claim (e.g. senior or subordinated). To capture the contingent nature of a program rating, Moody’s assigns provisional ratings to MTN programs. A provisional rating is denoted by a (P) in front of the rating.

The rating assigned to a drawdown from a rated MTN or bank/deposit note program is definitive in nature, and may differ from the program rating if the drawdown is exposed to additional credit risks besides the issuer’s default, such as links to the defaults of other issuers, or has other structural features that warrant a different rating. In some circumstances, no rating may be assigned to a drawdown.

Moody’s encourages market participants to contact Moody’s Ratings Desks or visit www.moodys.com directly if they have questions regarding ratings for specific notes issued under a medium-term note program. Unrated notes issued under an MTN program may be assigned an NR (not rated) symbol.

U.S. Municipal Short-Term Debt and Demand Obligation Ratings

Short-Term Obligation Ratings

Moody’s uses the global short-term Prime rating scale for commercial paper issued by US municipalities and nonprofits. These commercial paper programs may be backed by external letters of credit or liquidity facilities, or by an issuer’s self-liquidity.

For other short-term municipal obligations, Moody’s uses one of two other short-term rating scales, the Municipal Investment Grade (MIG) and Variable Municipal Investment Grade (VMIG) scales discussed below.

Moody’s uses the MIG scale for US municipal cash flow notes, bond anticipation notes and certain other short-term obligations, which typically mature in three years or less. Under certain circumstances, we use the MIG scale for bond anticipation notes with maturities of up to five years.

A-3

MIG 1 This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.

MIG 2 This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.

MIG 3 This designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established.

SG     This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

Demand Obligation Ratings

In the case of variable rate demand obligations (VRDOs), a two-component rating is assigned. The components are a long-term rating and a short-term demand obligation rating. The long-term rating addresses the issuer’s ability to meet scheduled principal and interest payments. The short-term demand obligation rating addresses the ability of the issuer or the liquidity provider to make payments associated with the purchase-price-upon-demand feature (“demand feature”) of the VRDO. The short-term demand obligation rating uses the VMIG scale. VMIG ratings with liquidity support use as an input the short-term Counterparty Risk Assessment of the support provider, or the long-term rating of the underlying obligor in the absence of third party liquidity support. Transitions of VMIG ratings of demand obligations with conditional liquidity support differ from transitions on the Prime scale to reflect the risk that external liquidity support will terminate if the issuer’s long-term rating drops below investment grade. Please see Moody’s methodology that discusses demand obligations with conditional liquidity support.

Fitch Ratings—A brief description of the applicable Fitch Ratings (“Fitch”) ratings symbols and meanings (as published by Fitch) follows:

A-4

Credit ratings express risk in relative rank order, which is to say they are ordinal measures of credit risk and are not predictive of a specific frequency of default or loss.

A-5

Within rating categories, Fitch may use modifiers. The modifiers “+” or “-” may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to ‘AAA’ ratings and ratings below the ‘CCC’ category.

Short-Term Ratings Assigned to Issuers and Obligations

A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-term deposit ratings may be adjusted for loss severity. Short-Term Ratings are assigned to obligations whose initial maturity is viewed as “short term” based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations, and up to 36 months for obligations in U.S. public finance markets.

Within rating categories, Fitch may use modifiers. The modifiers “+” or “-“ may be appended to a rating to denote relative status within major rating categories. For the short-term rating category of ‘F1’, a ‘+’ may be appended.

Specific Limitations Relevant to Ratings Assigned Using the Primary Credit Rating Scale, Bank Viability Ratings and Bank Support Ratings

The following specific limitations relate to issuer default scales, ratings assigned to corporate finance obligations, ratings assigned to public finance obligations, ratings assigned to structured finance transactions, ratings assigned to global infrastructure and project finance transactions, ratings assigned for banks (Viability Ratings, Support Ratings, Support Floors), derivative counterparty ratings and insurer financial strength ratings.

A-6

The ratings do not opine on any quality related to an issuer’s business, operational or financial profile other than the agency’s opinion on its relative vulnerability to default. For the avoidance of doubt, not all defaults will be considered a default for rating purposes. Typically, a default relates to a liability payable to an unaffiliated, outside investor.

The ratings do not opine on any quality related to a transaction’s profile other than the agency’s opinion on the relative vulnerability to default of an issuer and/or of each rated tranche or security.

The ratings do not predict a specific percentage of extraordinary support likelihood over any given period.

The ratings do not opine on the suitability of any security for investment or any other purposes.

A-7
