The Funds’ History
American Century International Bond Funds is a registered open-end management investment company that was organized as a Massachusetts business trust in 1991 under the name Benham International Funds. In October 1996, it changed its name to American Century International Bond Funds. Throughout this statement of additional information we refer to American Century International Bond Funds as the trust. The trust’s fiscal year end was changed from December 31 to June 30 beginning on January 1, 2007. Beginning October 31, 2015, the trust changed its fiscal year end from June 30 to October 31.
Each fund described in this statement of additional information is a separate series of the trust and operates for many purposes as if it were an independent company. Each fund has its own investment objective, strategy, management team, assets and tax identification and stock registration numbers.

Fund Investment Guidelines
This section explains the extent to which the funds’ advisor, American Century Investment Management, Inc. (ACIM), can use various investment vehicles and strategies in managing a fund’s assets. Descriptions of the investment techniques and risks associated with each appear in the section Investment Strategies and Risks, which begins on page 5. In the case of the funds’ principal investment strategies, these descriptions elaborate upon the discussion contained in the prospectus.
Global Bond and Emerging Markets Debt are diversified as defined in the Investment Company Act of 1940 (the Investment Company Act). Diversified means that, with respect to 75% of its total assets, a fund will not invest more than 5% of its total assets in the securities of a single issuer or own more than 10% of the outstanding voting securities of a single issuer (other than U.S. government securities and securities of other investment companies).
International Bond is nondiversified. Nondiversified means that a fund may invest a greater percentage of its assets in a smaller number of securities than a diversified fund. 
To meet federal tax requirements for qualification as a regulated investment company, each fund must limit its investments so that at the close of each quarter of its taxable year
(1)no more than 25% of its total assets are invested in the securities of a single issuer (other than the U.S. government or a regulated investment company); and
(2)with respect to at least 50% of its total assets, no more than 5% of its total assets are invested in the securities of a single issuer (other than the U.S. government or a regulated investment company) and it does not own more than 10% of the outstanding voting securities of a single issuer.
Investments are varied according to what is judged advantageous under changing economic conditions. It is the advisor’s policy to retain maximum flexibility in management without restrictive provisions as to the proportion of one or another class of securities that may be held, subject to the investment restrictions described below. Subject to the specific limitations applicable to a fund, the fund management teams may invest the assets of each fund in varying amounts in other instruments when such a course is deemed appropriate in order to pursue a fund’s investment objective. Unless otherwise noted, all investment restrictions described below and in each fund’s prospectus are measured at the time of the transaction in the security. If market action affecting fund securities (including, but not limited to, appreciation, depreciation or a credit rating event) causes a fund to exceed an investment restriction, the advisor is not required to take immediate action. Under normal market conditions, however, the advisor’s policies and procedures indicate that the advisor will not make any purchases that will make the fund further outside the investment restriction.
Emerging Markets Debt Fund
Under normal market conditions, the fund invests at least 80% of its net assets in fixed income instruments of issuers that are economically tied to emerging markets. The fund will invest in debt instruments issued by foreign governments and corporations. Investments are made in instruments denominated in U.S. dollars and in local emerging markets currency.
In determining an issuer’s location, the portfolio managers may consider various factors including, among others, where the issuer is headquartered, where the issuer’s principal operations are located, where a majority of the issuer’s revenues are derived, where the principal trading market is located and the country in which the issuer was legally organized. The weight given to each of these factors will vary depending on the circumstances in a given case.
The fund may invest without limitation in both investment grade and high-yield securities. An “investment grade” security is one that has been rated in one of the four highest categories used by a nationally recognized statistical organization or determined by the investment advisor to be of comparable credit quality. A “high-yield” security is one that has been rated below the four highest categories used by a nationally recognized statistical rating organization, or determined by the investment advisor to be of similar quality.
The fund also invests in derivative instruments, including foreign currency exchange contracts, in order to shift its investment exposure from one currency into another for hedging purposes or to enhance returns. The fund may also invest in other types of derivative instruments such as futures contracts and swap agreements in order to manage duration, credit exposure and country exposure.
Global Bond Fund
Under normal market conditions, the fund invests at least 80% of its net assets in bonds. For purposes of this fund, the advisor defines bonds as non-money market debt securities which may be payable in U.S. or foreign currencies, and which may include U.S. and foreign corporate bonds and notes, government securities, commercial paper and securities backed by mortgages or other assets. The fund generally hedges most of its foreign currency exposure to the U.S. dollar. 
The fund invests primarily in companies located in developed countries world-wide (including the United States), but may also invest in emerging markets. Under normal market conditions, the fund will invest at least 40% of its assets in foreign investments (unless the portfolio managers deem market conditions unfavorable, in which case the fund would invest at least 30% of its assets in foreign investments). The fund will allocate its assets among at least three different countries (one of which may be the United States). 
3


The fund may invest up to 35% of its assets in high-yield securities. A high-yield security is one that has been rated below the four highest categories used by a nationally recognized statistical rating organization, or determined by the investment advisor to be of similar quality.
The fund may invest in securities issued or guaranteed by the U.S. Treasury and certain U.S. government agencies or instrumentalities such as the Government National Mortgage Association (Ginnie Mae). Ginnie Mae is supported by the full faith and credit of the U.S. government. The fund may also invest in securities issued or guaranteed by other U.S. government agencies or instrumentalities, such as the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac), and the Federal Home Loan Bank (FHLB), which are not guaranteed by the U.S. Treasury or supported by the full faith and credit of the U.S. government. However, they are authorized to borrow from the U.S. Treasury to meet their obligations. 
The fund also invests in derivative instruments, including foreign currency exchange contracts, in order to shift its investment exposure from one currency into another for hedging purposes or to enhance returns. The fund may also invest in other types of derivative instruments such as futures contracts and swap agreements in order to manage duration, credit exposure and country exposure. In certain foreign markets, swaps can also act as substitutes for other less liquid fixed-income instruments.
International Bond Fund
For purposes of this fund, the advisor defines bonds as non-money market debt securities, such as corporate bonds and notes, securities issued by governments, commercial paper and securities backed by mortgages or other assets. Under normal market conditions, the fund will invest at least 80% of its net assets in bonds.
The fund may invest in both investment grade and high-yield debt securities. The fund may also invest in emerging markets debt securities.
In determining an issuer’s location, the portfolio managers may consider various factors including, among others, where the issuer is headquartered, where the issuer’s principal operations are located, where a majority of the issuer’s revenues are derived, where the principal trading market is located and the country in which the issuer was legally organized. The weight given to each of these factors will vary depending on the circumstances in a given case. 
The fund’s investments may include but shall not be limited to: (1) debt obligations issued or guaranteed by (a) a foreign sovereign government or one of its agencies, authorities, instrumentalities or political subdivisions including a foreign state, province or municipality, and (b) supranational organizations such as the World Bank, Asian Development Bank, European Investment Bank, and European Economic Community; (2) debt obligations of (a) foreign banks and bank holding companies, and (b) domestic banks and corporations issued in foreign currencies; and (3) foreign corporate debt securities and commercial paper.
Some securities will also have the country of issue reported as ‘Supranational.’ These are organizations that cannot be aligned with one particular country, such as the International Finance Corporation or the European Development Bank.
For an explanation of the securities ratings referred to in the prospectus and this statement of additional information, see Explanation of Fixed-Income Securities Ratings in Appendix D
Currency Management 
The rate of exchange between U.S. dollars and foreign currencies fluctuates, which results in gains and losses to the funds. Even if the funds’ foreign security holdings perform well, an increase in the value of the dollar relative to the currencies in which portfolio securities are denominated can offset net investment income.
The advisor intends to hedge the currency risk of Global Bond Fund to help lower the price volatility associated with currency risk. The fund will normally limit its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 30% of its total assets.
Because International Bond Fund is designed for U.S. investors seeking currency and interest rate diversification, the fund’s advisor limits its use of hedging strategies intended to minimize the effect of currency fluctuations. Although hedging strategies (if they are successful) reduce exchange rate risk, they also reduce the potential for share price appreciation when foreign currencies increase in value relative to the U.S. dollar.
When the advisor considers the U.S. dollar to be attractive relative to foreign currencies, as much as 25% of International Bond Fund’s total assets may be hedged into U.S. dollars. For temporary defensive purposes and under extraordinary circumstances (such as significant political events), more than 25% of the fund’s total assets may be hedged in this manner.
In managing the funds’ currency exposure, the advisor will buy and sell foreign currencies regularly, either in the spot (i.e., cash) market or the forward market. Forward foreign currency exchange contracts (forward contracts) are individually negotiated and privately traded between currency traders (usually large commercial banks) and their customers. In most cases, no deposit requirements exist, and these contracts are traded at a net price without commission. Forward contracts involve an obligation to purchase or sell a specific currency at an agreed-upon price on a future date. Most contracts expire in less than one year. The funds also may use futures and options for currency management purposes. For more information on futures and options, please see Futures and Options on page 15.

Fund Investments and Risks
Investment Strategies and Risks
This section describes investment vehicles and techniques the portfolio managers can use in managing a fund’s assets. It also details the risks associated with each, because each investment vehicle and technique contributes to a fund’s overall risk profile. 
Asset-Backed Securities (ABS)
To the extent permitted by its investment objective, each fund may invest in ABS. ABS are structured like mortgage-backed securities, but instead of mortgage loans or interest in mortgage loans, the underlying assets may include, for example, such items as motor vehicle installment sales or installment loan contracts, leases of various types of real and personal property, home equity loans, student loans, small business loans, and receivables from credit card agreements. The ability of an issuer of ABS to enforce its security interest in the underlying assets may be limited. The value of an ABS is affected by changes in the market’s perception of the assets backing the security, the creditworthiness of the servicing agent for the loan pool, the originator of the loans, the financial institution providing any credit enhancement, and subordination levels. 
Payments of principal and interest passed through to holders of ABS are typically supported by some form of credit enhancement, such as a letter of credit, surety bond, limited guarantee by another entity or a priority to certain of the borrower’s other securities. The degree of credit enhancement varies, and generally applies to only a fraction of the asset-backed security’s par value until exhausted. If the credit enhancement of an ABS held by a fund has been exhausted, and if any required payments of principal and interest are not made with respect to the underlying loans, a fund may experience losses or delays in receiving payment.
Some types of ABS may be less effective than other types of securities as a means of “locking in” attractive long-term interest rates. One reason is the need to reinvest prepayments of principal; another is the possibility of significant unscheduled prepayments resulting from declines in interest rates. These prepayments would have to be reinvested at lower rates. As a result, these securities may have less potential for capital appreciation during periods of declining interest rates than other securities of comparable maturities, although they may have a similar risk of decline in market value during periods of rising interest rates. Prepayments may also significantly shorten the effective maturities of these securities, especially during periods of declining interest rates. Conversely, during periods of rising interest rates, a reduction in prepayments may increase the effective maturities of these securities, subjecting them to a greater risk of decline in market value in response to rising interest rates than traditional debt securities, and, therefore, potentially increasing the volatility of a fund. 
The risks of investing in ABS are ultimately dependent upon the repayment of loans by the individual or corporate borrowers. Although a fund would generally have no recourse against the entity that originated the loans in the event of default by a borrower, ABS typically are structured to mitigate this risk of default. 
ABS are generally issued in more than one class, each with different payment terms. Multiple class ABS may be used as a method of providing credit support through creation of one or more classes whose right to payments is made subordinate to the right to such payments of the remaining class or classes. Multiple classes also may permit the issuance of securities with payment terms, interest rates or other characteristics differing both from those of each other and from those of the underlying assets. Examples include so-called strips (ABS entitling the holder to disproportionate interests with respect to the allocation of interest and principal of the assets backing the security), and securities with classes having characteristics such as floating interest rates or scheduled amortization of principal.
Bank Loans 
Each fund may invest in bank loans, which include senior secured and unsecured floating rate loans of corporations, partnerships, or other entities. Typically, these loans hold a senior position in the borrower’s capital structure, may be secured by the borrower’s assets and have interest rates that reset frequently. These loans are usually rated non-investment grade by the rating agencies. An economic downturn generally leads to higher non-payment and default rates by borrowers, and a bank loan can lose a substantial part of its value due to these and other adverse conditions and events. However, as compared to junk bonds, senior floating rate loans are typically senior in the capital structure and are often secured by collateral of the borrower. A fund’s investments in bank loans are subject to credit risk, and there is no assurance that the liquidation of collateral would satisfy the claims of the borrower’s obligations in the event of non-payment of scheduled interest or principal, or that the collateral could be readily liquidated. The interest rates on many bank loans reset frequently, and therefore investors are subject to the risk that the return will be less than anticipated when the investment was first made. Most bank loans, like most investment grade bonds, are not traded on any national securities exchange. Bank loans generally have less liquidity than investment grade bonds and there may be less publicly available information about them. 
A fund eligible to invest in bank loans may purchase bank loans from the primary market, from other lenders (sometimes referred to as loan assignments) or it may also acquire a participation interest in another lender’s portion of the bank loan. Large bank loans to corporations or governments may be shared or syndicated among several lenders, usually commercial or investment banks. A fund may participate in such syndicates, or can buy part of a loan, becoming a direct lender. Participation interests involve special types of risk, including liquidity risk and the risks of being a lender. Risks of being a lender include credit risk (the borrower’s ability to meet
5


required principal and interest payments under the terms of the loan), industry risk (the borrower’s industry’s exposure to rapid change or regulation), financial risk (the effectiveness of the borrower’s financial policies and use of leverage), liquidity risk (the adequacy of the borrower’s back-up sources of cash), and collateral risk (the sufficiency of the collateral’s value to repay the loan in the event of non-payment or default by the borrower). If a fund purchases a participation interest, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the credit risk of the borrower. 
In addition, transactions in bank loans may take more than seven days to settle. As a result, the proceeds from the sale of bank loans may not be readily available to make additional investments or to meet the fund’s redemption obligations. To mitigate these risks, the fund monitors its short-term liquidity needs in light of the longer settlement period of bank loans. Some bank loan interests may not be registered under the Securities Act of 1933 and therefore not afforded the protections of the federal securities laws.
Collateralized Debt Obligations
Each fund may invest in collateralized debt obligations (“CDOs”), including collateralized loan obligations (“CLOs”), collateralized bond obligations (“CBOs”), and other similarly structured securities. CBOs and CLOs are types of asset backed securities. A CLO is a trust or other special purpose entity that is typically collateralized by a pool of loans, which may include, among others, U.S. and non-U.S. senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. A CBO is generally a trust which is backed by a diversified pool of high risk, below investment grade fixed income securities. The risks of an investment in a CDO depend largely on the type of the collateral backing the obligation and the class of the CDO in which a fund invests. CDOs are subject to credit, interest rate, valuation, prepayment and extension risks. These securities are also subject to risk of default on the underlying asset, particularly during periods of economic downturn. CDOs carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments, (ii) the collateral may decline in value or default, (iii) a fund may invest in CDOs that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.
Commercial Paper
The funds may invest in commercial paper (CP) that is issued by utility, financial, and industrial companies, supranational organizations and foreign governments and their agencies and instrumentalities. Rating agencies assign ratings to short-term securities (including CP) issuers indicating the agencies’ assessment of credit risk. Short-term ratings assigned by certain rating agencies are provided in Explanation of Fixed-Income Securities Ratings, Appendix D.
Some examples of CP and CP issuers are provided in the following paragraphs. 
Domestic CP is issued by U.S. industrial and finance companies, utility companies, thrifts and bank holding companies. Foreign CP is issued by non-U.S. industrial and finance companies and financial institutions. Domestic and foreign corporate issuers occasionally have the underlying support of a well-known, highly rated commercial bank or insurance company. Bank support is provided in the form of a letter of credit (an LOC) or irrevocable revolving credit commitment (an IRC). Insurance support is provided in the form of a surety bond.
Bank holding company CP is issued by the holding companies of many well-known domestic banks, including Citicorp, J.P. Morgan Chase & Company and First Union National Bank. Bank holding company CP may be issued by the parent of a money center or regional bank.
Thrift CP is issued by major federal- or state-chartered savings and loan associations and savings banks. 
Schedule B Bank CP is short-term, U.S. dollar-denominated CP issued by Canadian subsidiaries of non-Canadian banks (Schedule B banks). Whether issued as CP, a certificate of deposit or a promissory note, each instrument issued by a Schedule B bank ranks equally with any other deposit obligation. CP issued by Schedule B banks provides an investor with the comfort and reduced risk of a direct and unconditional parental bank guarantee.
Schedule B instruments generally offer higher rates than the short-term instruments of the parent bank or holding company.
Asset-backed CP is issued by corporations through special programs. In a typical program, a special purpose corporation (SPC), created and/or serviced by a bank or other financial institution, uses the proceeds from an issuance of CP to purchase receivables or other financial assets from one or more corporations (sellers). The sellers transfer their interest in the receivables or other financial assets to the SPC, and the cash flow from the receivables or other financial assets is used to pay interest and principal on the CP. Letters of credit or other forms of credit enhancement may be available to cover the risk that the cash flow from the receivables or other financial assets will not be sufficient to cover the maturing CP.
Convertible Securities
The funds may invest in convertible securities. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular time period at a specified price or formula. A convertible security entitles the holder to receive the interest paid or accrued on debt or the dividend paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. Before conversion or exchange, such securities ordinarily provide a stream of income with generally higher yields than common stocks of the same or
6


similar issuers, but lower than the yield on non-convertible debt. Of course, there can be no assurance of current income because issuers of convertible securities may default on their obligations. In addition, there can be no assurance of capital appreciation because the value of the underlying common stock will fluctuate. Because of the conversion feature, the managers consider some convertible securities to be equity equivalents.
The price of a convertible security will normally fluctuate in some proportion to changes in the price of the underlying asset. A convertible security is subject to risks relating to the activities of the issuer and/or general market and economic conditions. The stream of income typically paid on a convertible security may tend to cushion the security against declines in the price of the underlying asset. However, the stream of income causes fluctuations based upon changes in interest rates and the credit quality of the issuer. In general, the value of a convertible security is a function of (1) its yield in comparison with yields of other securities of comparable maturity and quality that do not have a conversion privilege and (2) its worth, at market value, if converted or exchanged into the underlying common stock. The price of a convertible security often reflects such variations in the price of the underlying common stock in a way that a non-convertible security does not. At any given time, investment value generally depends upon such factors as the general level of interest rates, the yield of similar nonconvertible securities, the financial strength of the issuer and the seniority of the security in the issuer’s capital structure.
A convertible security may be subject to redemption at the option of the issuer at a predetermined price. If a convertible security held by a fund is called for redemption, the fund would be required to permit the issuer to redeem the security and convert it to underlying common stock or to cash, or would sell the convertible security to a third party, which may have an adverse effect on the fund. A convertible security may feature a put option that permits the holder of the convertible security to sell that security back to the issuer at a predetermined price. A fund generally invests in convertible securities for their favorable price characteristics and total return potential and normally would not exercise an option to convert unless the security is called or conversion is forced.
Contingent convertible securities (sometimes referred to as CoCos) generally either convert into equity or have their principal written down upon the occurrence of certain trigger events, which may be linked to the issuer’s stock price, regulatory capital thresholds, regulatory actions relating to the issuer’s continued viability, or other pre-specified events. Under certain circumstances, CoCos may be subject to an automatic write-down of the principal amount or value of the securities, sometimes to zero, thereby cancelling the securities. If such an event occurs, a fund may not have any rights to repayment of the principal amount of the securities that has not become due. Additionally, a fund may not be able to collect interest payments or dividends on such securities once the write-down has occurred. In the event of liquidation or dissolution of the issuer, CoCos generally rank junior to the claims of holders of the issuer’s other debt obligations. CoCos also may provide for the mandatory conversion of the security into common stock of the issuer under certain circumstances. Because the common stock of an issuer may not pay a dividend, a fund may experience reduced yields (or no yield) as a result of the conversion. Conversion of the security from debt to equity would deepen the subordination of the investor and thereby worsen the fund’s standing in bankruptcy.
Counterparty Risk
A fund will be exposed to the credit risk of the counterparties with which, or the brokers, dealers and exchanges through which, it deals, whether it engaged in exchange traded or off-exchange transactions. If a fund’s futures commission merchant, (FCM) becomes bankrupt or insolvent, or otherwise defaults on its obligations to the fund, the fund may not receive all amounts owed to it in respect of its trading, despite the clearinghouse fully discharging all of its obligations. The Commodity Exchange Act requires an FCM to segregate all funds received from its customers with respect to regulated futures transactions from such FCM’s proprietary funds. If an FCM were not to do so to the full extent required by law, the assets of an account might not be fully protected in the event of the bankruptcy of an FCM. Furthermore, in the event of an FCM’s bankruptcy, a fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of an FCM’s combined customer accounts, even though certain property specifically traceable to the fund (for example, U.S. Treasury bills deposited by the fund) was held by an FCM. FCM bankruptcies have occurred in which customers were unable to recover from the FCM’s estate the full amount of their funds on deposit with such FCM and owing to them. Such situations could arise due to various factors, or a combination of factors, including inadequate FCM capitalization, inadequate controls on customer trading and inadequate customer capital. In addition, in the event of the bankruptcy or insolvency of a clearinghouse, the fund might experience a loss of funds deposited through its FCM as margin with the clearinghouse, a loss of unrealized profits on its open positions, and the loss of funds owed to it as realized profits on closed positions. Such a bankruptcy or insolvency might also cause a substantial delay before the fund could obtain the return of funds owed to it by an FCM who was a member of such clearinghouse.
Because bi-lateral derivative transactions are traded between counterparties based on contractual relationships, a fund is subject to the risk that a counterparty will not perform its obligations under the related contracts. Although each fund intends to enter into transactions only with counterparties which the advisor believes to be creditworthy, there can be no assurance that a counterparty will not default and that the funds will not sustain a loss on a transaction as a result. In situations where a fund is required to post margin or other collateral with a counterparty, the counterparty may fail to segregate the collateral or may commingle the collateral with the counterparty’s own assets. As a result, in the event of the counterparty’s bankruptcy or insolvency, a fund’s collateral may be subject to the conflicting claims of the counterparty’s creditors, and a fund may be exposed to the risk of a court treating a fund as a general unsecured creditor of the counterparty, rather than as the owner of the collateral.
7


A fund is subject to the risk that issuers of the instruments in which it invests and trades may default on their obligations under those instruments, and that certain events may occur that have an immediate and significant adverse effect on the value of those instruments. There can be no assurance that an issuer of an instrument in which a fund invests will not default, or that an event that has an immediate and significant adverse effect on the value of an instrument will not occur, and that a fund will not sustain a loss on a transaction as a result.
Transactions entered into by a fund may be executed on various U.S. and non-U.S. exchanges, and may be cleared and settled through various clearinghouses, custodians, depositories and prime brokers throughout the world. Although a fund attempts to execute, clear and settle the transactions through entities the advisor believes to be sound, there can be no assurance that a failure by any such entity will not lead to a loss to a fund.
Cyber Security Risk
As the funds increasingly rely on technology and information systems to operate, they become susceptible to operational risks linked to security breaches in those information systems. Both calculated attacks and unintentional events can cause failures in the funds’ information systems. Cyber attacks can include acquiring unauthorized access to information systems, usually through hacking or the use of malicious software, for purposes of stealing assets or confidential information, corrupting data, or disrupting fund operations. Cyber attacks can also occur without direct access to information systems, for example by making network services unavailable to intended users. Cyber security failures by, or breaches of the information systems of, the advisor, distributors, broker-dealers, other service providers (including, but not limited to, index providers, fund accountants, custodians, transfer agents and administrators), or the issuers of securities the fund invests in may also cause disruptions and impact the funds’ business operations. Breaches in information security may result in financial losses, interference with the funds’ ability to calculate NAV, impediments to trading, inability of fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. Additionally, the funds may incur substantial costs to prevent future cyber incidents. The funds have business continuity plans in the event of, and risk management systems to help prevent, such cyber attacks, but these plans and systems have limitations including the possibility that certain risks have not been identified. Moreover, the funds do not control the cyber security plans and systems of our service providers and other third party business partners. The funds and their shareholders could be negatively impacted as a result.
Derivative Instruments
To the extent permitted by its investment objectives and policies, a fund may invest in instruments that are commonly referred to as derivative instruments. Generally, a derivative instrument is a financial arrangement, the value of which is based on, or derived from, a traditional security, asset, or market index. Examples of common derivative instruments include futures contracts, warrants, structured notes, credit default swaps, options contracts, swap transactions and forward currency contracts. 
Certain derivative instruments may be described as structured investments. A structured investment is a security whose value or performance is linked to an underlying index or other security or asset class. Structured investments include asset-backed securities (ABS), commercial and residential mortgage-backed securities (MBS and CMBS), and collateralized mortgage obligations (CMO), which are described more fully herein. Structured investments also include securities backed by other types of collateral. Structured investments involve the transfer of specified financial assets to a special purpose entity, generally a corporation or trust, or the deposit of financial assets with a custodian; and the issuance of securities or depositary receipts backed by, or representing interests in, those assets.
Some structured investments are individually negotiated agreements or are traded over the counter. Structured investments may be organized and operated to restructure the investment characteristics of the underlying security. The cash flow on the underlying instruments may be apportioned among the newly issued structured investments to create securities with different investment characteristics, such as varying maturities, payment priorities and interest rate provisions, and the extent of such payments made with respect to structured investments is dependent on the extent of the cash flow on the underlying instruments. Because structured investments typically involve no credit enhancement, their credit risk generally will be equivalent to that of the underlying instruments. Structured investments are subject to such risks as the inability or unwillingness of the issuers of the underlying securities to repay principal and interest, and requests by the issuers of the underlying securities to reschedule or restructure outstanding debt and to extend additional loan amounts.
Some derivative instruments, such as mortgage-related and other asset-backed securities, are in many respects like any other investment, although they may be more volatile or less liquid than more traditional debt securities.
There are many different types of derivative instruments and many different ways to use them. Futures and options are commonly used for traditional hedging purposes to attempt to protect a fund from exposure to changing interest rates, securities prices or currency exchange rates, and for cash management purposes as a low-cost method of gaining exposure to a particular securities market without investing directly in those securities.
The return on a derivative instrument may increase or decrease, depending upon changes in the reference index or instrument to which it relates.
There is a range of risks associated with investments in derivatives, including:
8


the risk that the underlying security, interest rate, market index or other financial asset will not move in the direction the portfolio managers anticipate or that the value of the structured or derivative instrument will not move or react to changes in the underlying security, interest rate, market index or other financial asset as anticipated;
the possibility that there may be no liquid secondary market may make it difficult or impossible to close out a position when desired;
the risk that daily limits on price fluctuations and speculative position limits on exchanges on which a fund may conduct its transactions in derivative instruments may prevent profitable liquidation of positions, subjecting a fund to the potential of greater losses;
the risk that adverse price movements in an instrument can result in a loss substantially greater than a fund’s initial investment;
the risk that a fund will have an obligation to deliver securities or currency pursuant to a derivatives transaction that such fund does not own at the inception of the derivatives trade;
the risk that the counterparty will fail to perform its obligations; and
the risk that a fund will be subject to higher volatility because some derivative instruments create leverage.
A fund may not invest in a derivative instrument if its credit, interest rate, liquidity, counterparty and other risks associated with ownership of the security are outside acceptable limits set forth in the fund’s prospectus.
The funds’ Board of Trustees has reviewed the advisor’s derivatives risk management program policy, which includes policies and procedures reasonably designed to manage a fund’s derivatives risk. Unless a fund qualifies as a “limited derivatives user,” the fund will be required to participate in the derivatives risk management program, which includes compliance with value-at-risk based leverage limits, oversight by a derivatives risk manager, and additional reporting and disclosure regarding its derivatives positions. A fund designated as a limited derivatives user has policies and procedures to manage its aggregate derivatives risk. The advisor will report on the derivatives risk management program to the Board of Trustees on a quarterly basis. The derivatives risk management program complies with recently adopted Rule 18f-4. In connection with the adoption of Rule 18f-4, the SEC also eliminated the existing asset segregation framework for covering derivatives and certain financial instruments.
Equity Equivalents
The funds may invest in preferred stocks, other equity securities and equity equivalents, such as convertible bonds, warrants and other securities that permit the fund to receive an equity interest in an issuer, the opportunity to acquire an equity interest in an issuer, or the opportunity to receive a return on its investment that permits the fund to benefit from the growth over time in the equity of an issuer. Equity equivalents also may include securities whose value or return is derived from the value or return of a different security. Depositary receipts are an example of the type of equity equivalent security in which the fund might invest.
Preferred stock is a type of equity security that generally pays dividends at a specified rate and has preference over common stock in the liquidation of assets and payment of dividends. Preferred stock may be structured similarly to a long-dated or perpetual bond and does not ordinarily carry voting rights. Unlike interest payments on a fixed-income security, preferred stock dividends generally are only payable if declared by the issuer’s board of directors. A board of directors, however, is usually not obligated to pay dividends even if they have accrued. Additionally, if an issuer of preferred stock experiences economic or financial difficulties, its preferred stock may lose value due to the reduced likelihood that its board of directors will declare a dividend. Preferred stocks are typically subordinated to bonds and other debt instruments in an issuer’s capital structure, in which case, preferred stock dividends are usually paid only after the company makes required payments to those bond and other debt holders. Consequently, the value of preferred stock may react more strongly than bonds and other debt to actual or perceived changes in a company’s financial condition or prospects. Preferred stock may be substantially less liquid than other securities.
Foreign Currency Exchange Transactions
Each fund expects to exchange dollars for its underlying currencies, and vice versa, in the normal course of managing the fund’s underlying investments. The advisor does not expect that a fund will hold currency that is not earning income on a regular basis, although a fund may do so temporarily when suitable investments are not available. A fund may purchase and sell currencies on a spot basis (i.e., for prompt delivery and settlement), or by entering into forward currency exchange contracts (also called forward contracts) or other contracts to purchase and sell currencies for settlement at a future date. A fund will incur costs in converting assets from one currency to another. Foreign exchange dealers may charge a fee for conversion; in addition, they realize a profit based on the difference (i.e., the spread) between the prices at which they buy and sell various currencies in the spot and forward markets. Thus, a dealer may offer to sell a foreign currency to a fund at one rate and repurchase it at a lesser rate should the fund desire to resell the currency to the dealer.
Each fund may use foreign currency forward contracts to enhance returns by increasing exposure to a foreign currency, or by shifting exposure to the fluctuations in the value of foreign currencies from one foreign currency to another foreign currency. Open positions in forwards used for non-hedging purposes will be covered by the segregation of liquid assets, marked to market daily. Forward contracts are agreements to exchange a specific amount of one currency for a specified amount of another at a future date. The date may be any agreed fixed number of days in the future. The amount of currency to be exchanged, the price at which the exchange will
9


take place, and the date of the exchange are negotiated when a fund enters into the contract and are fixed for the term of the contract. Forward contracts are traded in an interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A forward contract generally has no deposit requirement and is consummated without payment of any commission. However, a fund may enter into forward contracts with deposit requirements or commissions.
At the maturity of a forward contract, a fund may complete the contract by paying for and receiving the underlying currency, or may seek to roll forward its contractual obligation by entering into an offsetting transaction with the same currency trader and paying or receiving the difference between the contractual exchange rate and the current exchange rate. A fund also may be able to enter into an offsetting contract prior to the maturity of the underlying contract. This practice is sometimes referred to as “cross hedging” and may be employed if, for example, the advisor believes that one foreign currency (in which a portion of a fund’s foreign currency holdings are denominated) will change in value relative to the U.S. dollar differently than another foreign currency. There is no assurance that offsetting transactions, or new forward contracts, will always be available to a fund.
Investors should realize that the use of forward contracts does not eliminate fluctuations in the underlying prices of the securities. Such contracts simply establish a rate of exchange that the fund can achieve at some future point in time. Additionally, although such contracts tend to minimize the risk of loss due to fluctuations in the value of the hedged currency when used as a hedge against foreign currency declines, at the same time they tend to limit any potential gain that might result from the change in the value of such currency.
Because investments in, and redemptions from, a fund will be in U.S. dollars, the advisor expects that a fund’s normal investment activity will involve a significant amount of currency exchange. For example, a fund may exchange its underlying foreign currencies for U.S. dollars in order to meet shareholder redemption requests or to pay expenses. These transactions may be executed in the spot or forward markets.
In addition, a fund may combine forward transactions in its underlying currency with investments in U.S. dollar-denominated instruments, in an attempt to construct an investment position whose overall performance will be similar to that of a security denominated in its underlying currency. If the amount of dollars to be exchanged is properly matched with the anticipated value of the dollar-denominated securities, a fund should be able to lock in the foreign currency value of the securities, and the fund’s overall investment return from the combined position should be similar to the return from purchasing a foreign currency-denominated instrument. This is sometimes referred to as a synthetic investment position or a position hedge.
The execution of a synthetic investment position may not be successful. It is impossible to forecast with absolute precision what the market value of a particular security will be at any given time. If the value of a dollar-denominated security is not exactly matched with a fund’s obligation under the forward contract on the contract’s maturity date, a fund may be exposed to some risk of loss from fluctuation of the dollar. Although the advisor will attempt to hold such mismatchings to a minimum, there can be no assurance that the advisor will be successful in doing so.
The funds may also invest in nondeliverable forward (NDF) currency transactions. An NDF is a transaction that represents an agreement between the fund and a counterparty to buy or sell a specified amount of a particular currency at an agreed upon foreign exchange rate on a future date. Unlike other currency transactions, there is no physical delivery of the currency on the settlement of an NDF transaction. Rather, the fund and the counterparty agree to net the settlement by making a payment in U.S. dollars or another fully convertible currency that represents any difference between the foreign exchange rate agreed upon at the inception of the NDF agreement and the actual exchange rate on the agreed upon future date. The funds may use an NDF contract to gain exposure to foreign currencies that are not internationally traded or if the markets for such currencies are heavily regulated or highly taxed. When currency exchange rates do not move as anticipated, a fund could sustain losses on the NDF transaction. This risk is heightened when the transactions involve currencies of emerging markets countries. Additionally, certain NDF transactions which involve currencies of less developed countries or certain other currencies, may be thinly traded or relatively illiquid.
Foreign Securities
Each fund invests in the securities of foreign issuers, including foreign governments, when these securities meet the fund’s standards of selection.
A description of the funds’ investment strategies regarding foreign securities is contained in the funds’ prospectuses. Investing in securities of foreign issuers generally involves greater risks than investing in the securities of domestic companies including:
Currency Risk – The value of the foreign investments held by a fund may be significantly affected by changes in currency exchange rates. The dollar value of a foreign security generally decreases when the value of the dollar rises against the foreign currency in which the security is denominated, and tends to increase when the value of the dollar falls against such currency. In addition, the value of fund assets may be affected by losses and other expenses incurred in converting between various currencies in order to purchase and sell foreign securities, and by currency restrictions, exchange control regulation, currency devaluations and political developments. Please see Currency Management on page 4 for more information. 
Social, Political and Economic Risk – The economies of many of the countries in which each fund invests are not as developed as the economy of the United States and may be subject to significantly different forces. Political or social instability, expropriation, nationalization, confiscatory taxation and limitations on the removal of funds or other assets also could adversely affect the value of
10


investments. Further, a fund may find it difficult or be unable to enforce ownership rights, pursue legal remedies or obtain judgments in foreign courts.
Regulatory Risk – Foreign companies generally are not subject to the regulatory controls imposed on U.S. issuers and, in general, there is less publicly available information about foreign securities than is available about domestic securities. Many foreign companies are not subject to uniform accounting, auditing and financial reporting standards, practices and requirements comparable to those applicable to domestic companies and there may be less stringent investor protection and disclosure standards in some foreign markets. Certain jurisdictions do not currently provide the Public Company Accounting Oversight Board (“PCAOB”) with sufficient access to inspect audit work papers and practices, or otherwise do not cooperate with U.S. regulators, potentially exposing investors in U.S. capital markets to significant risks.Income from foreign securities owned by a fund may be reduced by a withholding tax at the source, which would reduce dividend income payable to shareholders. 
Market and Trading Risk – Brokerage commission rates in foreign countries, which generally are fixed rather than subject to negotiation as in the United States, are likely to be higher. The securities markets in many of the countries in which a fund invests will have substantially less trading volume than the principal U.S. markets. As a result, the securities of some companies in these countries may be less liquid, more volatile and harder to value than comparable U.S. securities. Furthermore, one securities broker may represent all or a significant part of the trading volume in a particular country, resulting in higher trading costs and decreased liquidity due to a lack of alternative trading partners. There generally is less government regulation and supervision of foreign stock exchanges, brokers and issuers, which may make it difficult to enforce contractual obligations. In addition, it may be more difficult in foreign countries to accurately determine appropriate brokerage commissions, taxes and other trading costs related to securities trades.
Clearance and Settlement Risk – Foreign securities markets also have different clearance and settlement procedures, and in certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions. Delays in clearance and settlement could result in temporary periods when assets of a fund are uninvested and no return is earned. The inability of a fund to make intended security purchases due to clearance and settlement problems could cause the fund to miss attractive investment opportunities. Inability to dispose of portfolio securities due to clearance and settlement problems could result either in losses to the fund due to subsequent declines in the value of the portfolio security or, if a fund has entered into a contract to sell the security, liability to the purchaser.
Ownership Risk – Evidence of securities ownership may be uncertain in many foreign countries. As a result, there is a risk that a fund’s trade details could be incorrectly or fraudulently entered at the time of the transaction, resulting in a loss to the fund.
Sanctions Risk – The U.S. may impose economic sanctions against companies in various sectors of certain countries. This could limit a fund’s investment opportunities in such countries, impairing the fund’s ability to invest in accordance with its investment strategy and/or to meet its investment objective. For example, a fund may be prohibited from investing in securities issued by companies subject to such sanctions. In addition, the sanctions may require a fund to freeze its existing investments in sanctioned companies, prohibiting the fund from selling or otherwise transacting in these investments. Current sanctions or the threat of potential sanctions may also impair the value or liquidity of affected securities and negatively impact a fund.
In early 2022, the United States and countries throughout the world imposed economic sanctions on Russia in response to its military invasion of Ukraine. The sanctions are broad and include restrictions on the Russian government as well as Russian companies, individuals, and banking entities. The sanctions and other measures, such as boycotts or changes in consumer preferences, will likely cause declines in the value and liquidity of Russian securities, downgrades in the credit ratings of Russian securities, devaluation of Russia’s currency, and increased market volatility and disruption in Russia and throughout the world. Sanctions and similar measures, such as banning Russia from financial transaction systems that facilitate international transfers of funds, could limit or prevent the funds from selling and buying impacted securities both in Russia and in other markets. Such measures will likely cause significant delay in the settlement of impacted securities transactions or prevent settlement all together. The lack of available market prices for such securities may cause the funds to use fair value procedures to value certain securities. The consequences of the war and sanctions may negatively impact other regional and global economic markets. Additionally, Russia may take counter measures or engage in retaliatory actions—including cyberattacks and espionage—which could further disrupt global markets and supply chains. Companies in other countries that do business with Russia and the global commodities market for oil and natural gas, especially, will likely feel the impact of the sanctions. The sanctions, together with the potential for a wider armed or cyber conflict, could increase financial market volatility globally and negatively impact the funds’ performance beyond any direct exposure to Russian issuers or securities.
Risk of Focusing Investment on Region or Country – Investing a significant portion of assets in one country or region makes a fund more dependent upon the political and economic circumstances of that particular country or region.
Eurozone Investment Risk – The Economic and Monetary Union of the European Union (EMU) is comprised of the European Union (EU) members that have adopted the euro currency. By adopting the euro as its currency, a member state relinquishes control of its own monetary policies and is subject to fiscal and monetary controls. EMU members could voluntarily abandon, or be forced out of, the euro. Such events could impact the market values of Eurozone and various other securities and currencies, cause redenomination of certain securities into less valuable local currencies, and create more volatile and illiquid markets. As a result, European countries are significantly affected by fiscal and monetary controls implemented by the EMU. The euro currency may not fully reflect the strengths and weaknesses of the various economies that comprise the EMU and Europe generally. Certain countries and regions in the
11


EU are experiencing significant financial difficulties. Some of these countries may be dependent on assistance from other European governments and institutions or agencies. Assistance may be dependent on a country’s implementation of reforms or reaching a certain level of performance. Failure to reach those objectives or an insufficient level of assistance could result in an economic downturn that could significantly affect the value of investments in those and other European countries. One or more countries could depart from the EU, which could weaken the EU and, by extension, its remaining members.
United Kingdom Investment Risk – Commonly known as “Brexit,” the United Kingdom’s exit from the EU occurred in January of 2021. The UK and the EU continue to work to establish regulatory frameworks for cooperation on financial services. Continuing uncertainty in the UK, EU, and other financial markets may result in volatility, fluctuations in asset values and exchange rates, decreased liquidity and unwillingness or inability of financial and other counterparties to enter into transactions.
Japanese Investment Risk – Each fund may invest in securities offered by Japanese issuers. The value of such securities may be significantly affected by economic, political and regulatory developments in Japan. The Japanese government contends with persistent economic problems, including deflation, a banking system that has suffered from non-performing loans, and tax laws that dampen growth. Other factors having a negative impact include a heavy government budget deficit and low interest rates.
The Japanese economy lacks diversification, relying heavily on a small number of industries, including the electronic machinery sector. Japan is relatively poor in natural resources, and so it is dependent on imports, especially in the agricultural sector. It also relies on international trade to procure commodities needed for its strong heavy industrial sector, and therefore it is vulnerable to fluctuations in commodity prices. Japan has a high volume of exports, partly due to the government’s protectionist policies, which have caused tension with Japan’s trading partners, including the United States.
Generally, Japanese corporations are required to provide less disclosure than that required by U.S. law and accounting practice. Japanese accounting and auditing practices differ significantly from U.S. standards in specific areas, including regarding unconsolidated subsidiaries and related structures. 
Risk of Investing in China – Investing in Chinese securities is riskier than investing in U.S. securities. Although the Chinese government is currently implementing reforms to promote foreign investment and reduce government economic control, there is no guarantee that the reforms will be ongoing or effective. Investing in China involves risk of loss due to nationalization, expropriation, and confiscation of assets and property. Losses may also occur due to new or expanded restrictions on foreign investments or repatriation of capital. Participants in the Chinese market are subject to less regulation and oversight than participants in the U.S. market. This may lead to trading volatility, difficulty in the settlement and recording of transactions, and uncertainty in interpreting and applying laws and regulations. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in the economies of any of China’s key trading partners may adversely affect the securities of Chinese issuers. Regional conflict could also have an adverse effect on the Chinese economy.
The SEC and the PCAOB continue to have concerns about their ability to inspect international auditing standards of U.S. companies operating in China and PCAOB-registered auditing firms in China. Because the SEC and PCAOB have limited access to information about these auditing firms and are restricted from inspecting the audit work and practices of registered accountants in China, there is the risk that material information about Chinese issuers may be unavailable. As a result, there is substantially greater risk that disclosures will be incomplete or misleading and, in the event of investor harm, substantially less access to recourse, in comparison to U.S. domestic companies.
The U.S. government may occasionally place restrictions on investments in Chinese companies. For example, in November 2020, an Executive Order was issued that prohibits U.S. persons from purchasing or investing in certain publicly-traded securities of companies identified as “Communist Chinese military companies” or in instruments that are designed to provide investment exposure to those companies. The companies identified may change from time to time. A fund may incur losses if more investors attempt to sell such securities or if the fund is unable to participate in an otherwise attractive investment. Securities that are or become prohibited may become less liquid and their market prices may decline. In addition, the market for securities of other Chinese-based issuers may also be negatively impacted, resulting in reduced liquidity and price declines.
Due to Chinese governmental restrictions on foreign ownership of companies in certain industries, Chinese operating companies often rely on variable interest entity (VIE) structures to raise capital from non-Chinese investors. In a VIE structure, a China-based operating company establishes an entity—typically offshore—that enters into service and other contracts with the Chinese company designed to provide economic exposure to the company. The offshore entity can then issue shares and debt instruments that are sold to non-Chinese investors. A China based operating company and the offshore VIE might appear to be the same company—because they are presented in a consolidated manner—but they are not. The relationship between China-based operating company and the offshore VIE is predicated entirely on contracts with the China-based company, not equity ownership. The Chinese government has never approved these structures and thus could determine at any time, and without notice, that the VIE’s underlying contractual arrangements violate Chinese law. If either the China-based company (or its officers, directors, or Chinese equity owners) breach those contracts, or Chinese law changes in a way that affects the enforceability of these arrangements, or those contracts are otherwise not enforceable under Chinese law, U.S. investors may suffer significant losses with limited recourse available.
Bond Connect Risk – The funds may invest in certain securities that are listed and traded through China’s Bond Connect Program (“Bond Connect”), which allows non-Chinese investors to purchase certain fixed-income investments available from China’s interbank bond market. Bond Connect uses the trading infrastructure of both Hong Kong and China and is therefore not available on trading holidays in those countries. As a result, prices of securities purchased through Bond Connect may fluctuate at times when a
12


fund is unable to add to or exit its position. Securities offered through Bond Connect may lose their eligibility for trading through the program at any time. If Bond Connect securities lose their eligibility for trading through the program, they may be sold but can no longer be purchased through Bond Connect. Bond Connect is subject to regulation by both Hong Kong and China, and there can be no assurance that further regulations will not affect the availability of securities in the program, the frequency of redemptions, or other limitations. In China, the Hong Kong Monetary Authority Central Money Markets Unit holds Bond Connect securities on behalf of investors (such as the funds) via accounts maintained with China’s two fixed-income securities clearinghouses. While these investors may hold beneficial interest in Bond Connect securities, courts in China have limited experience in applying the concept of beneficial ownership. Additionally, a fund may not be able to participate in corporate actions affecting Bond Connect securities due to time constraints or for other operational reasons. As a result, payments of distributions could be delayed. Bond Connect trades are settled in Chinese currency, the renminbi (“RMB”). It cannot be guaranteed that investors will have timely access to a reliable supply of RMB in Hong Kong.
Emerging Markets
The funds may invest in emerging markets to the extent set forth in the prospectuses or in other sections of this SAI, and these investments present greater risk than investing in foreign issuers in general.
The funds may invest in emerging markets securities. The funds consider a security to be an emerging markets security if its issuer is located outside the following developed countries list, which is subject to change: Australia, Austria, Belgium, Bermuda, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United States. 
Repatriation of investment income, capital, and the proceeds of sales by foreign investors may require governmental registration and/or approval in some emerging markets countries. A number of the currencies of developing countries have experienced significant declines against the U.S. dollar in the past, and devaluation may occur subsequent to investments in these currencies by a fund. Inflation and rapid fluctuations in inflation rates have had and may continue to have negative effects on the economies and securities markets of certain emerging markets countries. Many of the emerging securities markets are relatively small, have low trading volumes, suffer periods of relative illiquidity, and are characterized by significant price volatility. There is the risk that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which could have a detrimental effect on a fund’s investments. Investing in many former communist or socialist countries involves the additional risk that the government or other executive or legislative bodies may decide not to continue to support economic reform programs and could follow radically different political and/or economic policies to the detriment of investors, including non-market oriented policies such as the support of certain industries at the expense of other sectors or a return to a completely centrally planned economy. It is possible, particularly in markets in emerging markets countries, that securities markets could be manipulated or that purported securities in which the funds invest may subsequently be found to be fraudulent and as a consequence the funds could suffer losses.
Additional risk factors include, but are not limited to, the following: varying custody, brokerage and settlement practices; difficulty in valuation and pricing; less public information about issuers of non-U.S. securities; less governmental regulation and supervision over the issuance and trading of securities; the unavailability of financial information regarding non-U.S. issuers or the difficulty of interpreting financial information prepared under non-U.S. accounting standards; the imposition of withholding and other taxes; adverse political, social or diplomatic developments; limitations on the movement of funds or other assets of an investor between different countries; difficulties in invoking the legal process outside the United States and enforcing contractual obligations; and the difficulty of assessing economic trends in non-U.S. countries. Investment in non-U.S. countries also involves higher brokerage and custodian expenses than does investment in U.S. securities traded on a U.S. securities exchange or market. The occurrence of adverse events affecting one particular emerging markets country or region could have more widespread effects and could adversely impact the global trading market for emerging markets instruments. Many of the laws that govern private and foreign investment, securities transactions and other contractual relationships in certain emerging markets countries are relatively new and largely untested. As a result, an investor may be subject to a number of unusual risks, including inadequate investor protection, contradictory legislation, incomplete, unclear and changing laws, disregard of regulations on the part of other market participants, lack of established or effective avenues for legal redress, absence of standard practices and confidentiality customs characteristic of more developed markets and lack of consistent enforcement of existing regulations. Furthermore, it may be difficult to obtain and/or enforce a judgment in certain countries in which assets of an investor are invested. There can be no assurance that this difficulty in protecting and enforcing rights will not have a material adverse effect on an investor (such as a fund) and its investments.
Company Debt – Governments of many emerging markets countries have exercised and continue to exercise substantial influence over many aspects of the private sector through the ownership or control of many companies, including some of the largest in any given country. As a result, government actions in the future could have a significant effect on economic conditions in emerging markets, which in turn, may adversely affect companies in the private sector, general market conditions and prices and yields of certain of the securities held by a fund. Expropriation, confiscatory taxation, nationalization, political, economic or social instability or other similar developments have occurred frequently over the history of certain emerging markets and could adversely affect the funds’ assets should these conditions recur. 
13


Sovereign Debt – Investment in sovereign debt can involve a high degree of risk. The issuers of the sovereign debt securities in which the funds may invest have in the past experienced substantial difficulties in servicing their external debt obligations, which have led to defaults on certain obligations and the restructuring of certain indebtedness. The governmental entity that controls the repayment of sovereign debt may not be able or willing to repay the principal and/or interest when due in accordance with the terms of such debt. A governmental entity’s willingness or ability to repay principal and interest due in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the governmental entity’s policy towards the International Monetary Fund and the political constraints to which a governmental entity may be subject. Governmental entities may also be dependent on expected disbursements from foreign governments, multilateral agencies and others abroad to reduce principal and interest averages on their debt. The commitment on the part of these governments, agencies and others to make such disbursements may be conditioned on a governmental entity’s implementation of economic reforms and/or economic performance and the timely service of such debtor’s obligations. Failure to implement such reforms, achieve such levels of economic performance or repay principal or interest when due may result in the cancellation of such third parties’ commitments to lend funds to the governmental entity, which may further impair such debtor’s ability or willingness to service its debts in a timely manner. Consequently, governmental entities may default on their sovereign debt. Holders of sovereign debt (including a fund) may be requested to participate in the rescheduling of such debt and to extend further loans to governmental entities. There is no bankruptcy proceeding by which sovereign debt on which governmental entities have defaulted may be collected in whole or in part. 
Emerging markets governmental issuers are among the largest debtors to commercial banks, foreign governments, international financial organizations and other financial institutions. Certain emerging markets governmental issuers have not been able to make payments of interest on or principal of debt obligations as those payments have come due. Obligations arising from past restructuring agreements may affect the economic performance and political and social stability of those issuers.
The ability of emerging markets governmental issuers to make timely payments on their obligations is likely to be influenced strongly by the issuer’s balance of payments, including export performance, and its access to international credits and investments. An emerging markets country whose exports are concentrated in a few commodities could be vulnerable to a decline in the international prices of one or more of those commodities. Increased protectionism on the part of an emerging markets country’s trading partners could also adversely affect the country’s exports and tarnish its trade account surplus, if any. To the extent that emerging markets countries receive payment for their exports in currencies other than U.S. dollars or non-emerging markets currencies, their ability to make debt payments denominated in U.S. dollars or non-emerging markets currencies could be affected. 
To the extent that an emerging markets country cannot generate a trade surplus, it must depend on continuing loans from foreign governments, multilateral organizations or private commercial banks, aid payments from foreign governments and on inflows of foreign investment. The access of emerging markets countries to these forms of external funding may not be certain, and a withdrawal of external funding could adversely affect the capacity of emerging markets country governmental issuers to make payments on their obligations. In addition, the cost of servicing emerging markets debt obligations can be affected by a change in international interest rates since the majority of these obligations carry interest rates that are adjusted periodically based upon international rates.
Another factor bearing on the ability of emerging markets countries to repay debt obligations is the level of international reserves of the country. Fluctuations in the level of these reserves affect the amount of foreign exchange readily available for external debt payments and thus could have a bearing on the capacity of emerging markets countries to make payments on these debt obligations.
Liquidity, Trading Volume, Regulatory Oversight – The securities markets of emerging markets countries are substantially smaller, less developed, less liquid and more volatile than the major securities markets in the United States. The lack of liquidity could have an adverse effect on the value of a fund’s holdings, and on a fund’s ability to dispose of such holdings in response to a specific adverse economic event, such as the deterioration in credit worthiness of a particular debtor.
The limited size of many emerging markets securities markets and limited trading volume in the securities of emerging markets issuers compared to the volume of trading in the securities of U.S. issuers could cause prices to be erratic for reasons apart from factors that affect the soundness and competitiveness of the securities issuers. Adverse publicity and investors’ perceptions, whether or not based on in-depth fundamental analysis, may decrease the value and liquidity of securities.
Disclosure and regulatory standards in emerging markets are in many respects less stringent than U.S. standards. Issuers in lesser developed and emerging markets are subject to accounting, auditing and financial standards and requirements that differ, in some cases significantly, from those applicable to U.S. issuers. In particular, the assets and profits appearing on the financial statements of such an issuer may not reflect its financial position or results of operations in the way they would be reflected had such financial statements been prepared in accordance with U.S. generally accepted accounting principles. There is substantially less publicly available information about such issuers than there is about U.S. issuers. In addition, such issuers are not subject to regulations similar to the U.S. Sarbanes-Oxley Act of 2002, which imposes many restrictions and mandates on the activities of companies. There is less regulation and monitoring by regulators of lesser developed and emerging markets securities markets and the activities of investors, brokers and other participants than in the United States. Moreover, issuers of securities in lesser developed and emerging markets are not subject to the same degree of regulation as are U.S. issuers with respect to such matters as insider trading rules, tender offer
14


regulation, shareholder proxy requirements and the timely disclosure of information. There is also less publicly available information about lesser developed and emerging markets companies than U.S. companies. 
Default, Legal Recourse – A fund may have limited legal recourse in the event of a default with respect to certain debt obligations it may hold. If the issuer of a fixed income security owned by a fund defaults, the fund may incur additional expenses to seek recovery. Debt obligations issued by emerging markets governments differ from debt obligations of private entities; remedies from defaults on debt obligations issued by emerging markets governments, unlike those on private debt, must be pursued in the courts of the defaulting party itself. A fund’s ability to enforce its rights against private issuers may be limited. The ability to attach assets to enforce a judgment may be limited. Legal recourse is therefore somewhat diminished. Bankruptcy, moratorium and other similar laws applicable to private issuers of debt obligations may be substantially different from those of other countries. Moreover, if a fund obtains a judgment in a U.S. court, it may be difficult to enforce such judgment in the emerging markets country because the country may not be a party to any international treaty with respect to the recognition or enforcement of foreign judgments. Provisions of an emerging markets country’s laws that regulate the enforcement of foreign judgments may contain broad exceptions and involve long delays in obtaining a judgment. For example, an emerging markets court may not enforce any foreign judgment if it viewed the amount of damages awarded as excessive or inconsistent with practice in that country. A party seeking to enforce a foreign judgment in an emerging markets country may also be required to obtain approval from the central bank of that country to execute such judgment or to repatriate any amount recovered outside of the emerging markets country. The political context, expressed as an emerging markets governmental issuer’s willingness to meet the terms of the debt obligation, for example, is of considerable importance. In addition, no assurance can be given that the holders of commercial bank debt may not contest payments to the holders of debt obligations in the event of default under commercial bank loan agreements.
Settlement Risk – Settlement and clearance procedures in certain foreign markets differ significantly from those in the United States. Foreign settlement and clearance procedures and trade regulations also may involve certain risks (such as delays in payment for or delivery of securities) not typically associated with the settlement of U.S. investments. At times, settlements in certain foreign countries have not kept pace with the number of securities transactions. These problems may make it difficult for a fund to carry out transactions. If a fund cannot settle or is delayed in settling a purchase of securities, it may miss attractive investment opportunities and certain of its assets may be uninvested with no return earned thereon for some period. If a fund cannot settle or is delayed in settling a sale of securities, it may lose money if the value of the security then declines or, if it has contracted to sell the security to another party, the fund could be liable for any losses incurred.
Inflation – Many emerging markets have experienced substantial, and in some periods extremely high, rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had and may continue to have adverse effects on the economies and securities markets of certain emerging markets countries. In an attempt to control inflation, wage and price controls have been imposed in certain countries.
Futures and Options
Each fund may enter into futures contracts, options or options on futures contracts. Futures contracts provide for the sale by one party and purchase by another party of a specific security at a specified future time and price. Generally, futures transactions will be used to: 
protect against a decline in market value of a fund’s securities (taking a short futures position),
protect against the risk of an increase in market value for securities in which a fund generally invests at a time when the fund is not fully-invested (taking a long futures position), or
provide a temporary substitute for the purchase of an individual security that may not be purchased in an orderly fashion.
Some futures and options strategies, such as selling futures, buying puts and writing calls, hedge the fund’s investments against price fluctuations. Other strategies, such as buying futures, writing puts and buying calls, tend to increase market exposure. 
Although other techniques may be used to control a fund’s exposure to market fluctuations, the use of futures contracts may be a more effective means of hedging this exposure. While a fund pays brokerage commissions in connection with opening and closing out futures positions, these costs are lower than the transaction costs incurred in the purchase and sale of the underlying securities.
For example, the sale of a future by a fund means a fund becomes obligated to deliver the security (or securities, in the case of an index future) at a specified price on a specified date. The purchase of a future means a fund becomes obligated to buy the security (or securities) at a specified price on a specified date. The portfolio manager may engage in futures and options transactions based on securities indices provided that the transactions are consistent with a fund’s investment objectives. Examples of indices that may be used include the Morgan Stanley Capital International Europe, Australasia, Far East Index (MSCI EAFE) and Morgan Stanley Capital International Emerging Markets Free Index (MSCI EMF). The portfolio manager also may engage in futures and options transactions based on specific securities, such as U.S. Treasury bonds or notes. Futures contracts are traded on national futures exchanges. Domestic futures exchanges and trading are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC), a U.S. government agency.
Index futures contracts differ from traditional futures contracts in that when delivery takes place, no stocks or bonds change hands. Instead, these contracts settle in cash at the spot market value of the index. Although other types of futures contracts by their terms call
15


for actual delivery or acceptance of the underlying securities, in most cases the contracts are closed out before the settlement date. A futures position may be closed by taking an opposite position in an identical contract (i.e., buying a contract that has previously been sold or selling a contract that has previously been bought).
Unlike when a fund purchases or sells a bond, no price is paid or received by a fund upon the purchase or sale of the future. Initially, a fund will be required to deposit an amount of cash or securities equal to a varying specified percentage of the contract amount. This amount is known as initial margin. The margin deposit is intended to ensure completion of the contract (delivery or acceptance of the underlying security) if it is not terminated prior to the specified delivery date. A margin deposit does not constitute a margin transaction for purposes of a fund’s investment restrictions. Minimum initial margin requirements are established by the futures exchanges and may be revised. In addition, brokers may establish margin deposit requirements that are higher than the exchange minimums. Cash held in the margin accounts generally is not income-producing. However, coupon bearing securities, such as Treasury bills and bonds, held in margin accounts generally will earn income. Subsequent payments to and from the broker, called variation margin, will be made on a daily basis as the price of the underlying debt securities or index fluctuates, making the future more or less valuable, a process known as marking the contract to market. Changes in variation margin are recorded by a fund as unrealized gains or losses.
At any time prior to expiration of the future, a fund may elect to close the position by taking an opposite position. A final determination of variation margin is then made; additional cash is required to be paid by or released to a fund and that fund realizes a loss or gain.
Purchasing Put and Call Options
By purchasing a put option, a fund obtains the right (but not the obligation) to sell the option’s underlying instrument at a fixed strike price. In return for this right, a fund pays the current market price for the option (known as the option premium). Options have various types of underlying instruments, including specific securities, indices of securities prices, and futures contracts. A fund may terminate its position in a put option it has purchased by allowing it to expire or by exercising the option. If the option is allowed to expire, a fund will lose the entire premium it paid. If a fund exercises the option, it completes the sale of the underlying instrument at the strike price. A fund also may terminate a put option position by closing it out in the secondary market at its current price if a liquid secondary market exists.
The buyer of a typical put option can expect to realize a gain if security prices fall substantially. However, if the underlying instrument’s price does not fall enough to offset the cost of purchasing the option, a put buyer can expect to suffer a loss (limited to the amount of the premium paid, plus related transaction costs).
The features of call options are essentially the same as those of put options, except that the purchaser of a call option obtains the right to purchase, rather than sell, the underlying instrument at the option’s strike price. A call buyer typically attempts to participate in potential price increases of the underlying instrument with risk limited to the cost of the option if security prices fall. At the same time, the buyer can expect to suffer a loss if security prices do not rise sufficiently to offset the cost of the option.
Writing Put and Call Options
If a fund writes a put option, it takes the opposite side of the transaction from the option’s purchaser. In return for receipt of the premium, a fund assumes the obligation to pay the strike price for the option’s underlying instrument if the other party chooses to exercise the option. When writing an option on a futures contract, a fund will be required to make margin payments to a broker or custodian as described above for futures contracts. A fund may seek to terminate its position in a put option it writes before exercise by closing out the option in the secondary market at its current price. However, if the secondary market is not liquid for a put option a fund has written, the fund must continue to be prepared to pay the strike price while the option is outstanding, regardless of price changes, and must continue to set aside assets to cover its position.
If security prices rise, a put writer would generally expect to profit, although the gain would be limited to the amount of the premium received. If security prices remain the same over time, the writer also would likely profit by being able to close out the option at a lower price. If security prices fall, the put writer would expect to suffer a loss. This loss should be less than the loss from purchasing the underlying instrument directly, however, because the premium received for writing the option should mitigate the effects of the decline. 
Writing a call option obligates a fund to sell or deliver the option’s underlying instrument in return for the strike price upon exercise of the option. The characteristics of writing call options are similar to those of writing put options, except that writing calls generally is a profitable strategy if prices remain the same or fall. Through receipt of the option premium, a call writer mitigates the effects of a price decline. At the same time, because a call writer must be prepared to deliver the underlying instrument in return for the strike price even if its current value is greater, a call writer gives up some ability to participate in security price increases.
Combined Positions
A fund may purchase and write options in combination with one another, or in combination with futures or forward contracts, to adjust the risk and return characteristics of the overall position. For example, a fund may purchase a put option and write a call option on the same underlying instrument to construct a combined position whose risk and return characteristics are similar to selling a futures contract. Another possible combined position would involve writing a call option at one strike price and buying a call option at a lower
16


price to reduce the risk of the written call option in the event of a substantial price increase. Because combined options positions involve multiple trades, they result in higher transaction costs and may be more difficult to open and close out.
Over-the-Counter Options
Unlike exchange-traded options, which are standardized with respect to the underlying instrument, expiration date, contract size, and strike price, the terms of over-the-counter (OTC) options (options not traded on exchanges) generally are established through negotiation with the other party to the option contract. While this type of arrangement allows the fund greater flexibility to tailor an option to its needs, OTC options generally involve greater credit risk than exchange-traded options, which are guaranteed by the clearing organizations of the exchanges where they are traded. The risk of illiquidity also is greater with OTC options because these options generally can be closed out only by negotiation with the other party to the option.
Risks Related to Futures and Options Transactions
Futures and options prices can be volatile, and trading in these markets involves certain risks. If the portfolio manager applies a hedge at an inappropriate time or judges interest rate trends incorrectly, futures and options strategies may lower a fund’s return.
A fund could suffer losses if it is unable to close out its position because of an illiquid secondary market. Futures contracts may be closed out only on an exchange that provides a secondary market for these contracts, and there is no assurance that a liquid secondary market will exist for any particular futures contract at any particular time. Consequently, it may not be possible to close a futures position when the portfolio manager considers it appropriate or desirable to do so. In the event of adverse price movements, a fund would be required to continue making daily cash payments to maintain its required margin. If a fund had insufficient cash, it might have to sell portfolio securities to meet daily margin requirements at a time when the portfolio manager would not otherwise elect to do so. In addition, a fund may be required to deliver or take delivery of instruments underlying futures contracts it holds. The portfolio manager will seek to minimize these risks by limiting the futures contracts entered into on behalf of a fund to those traded on national futures exchanges and for which there appears to be a liquid secondary market.
A fund could suffer losses if the prices of its futures and options positions were poorly correlated with its other investments, or if securities underlying futures contracts purchased by a fund had different maturities than those of the portfolio securities being hedged. Such imperfect correlation may give rise to circumstances in which a fund loses money on a futures contract at the same time that it experiences a decline in the value of its hedged portfolio securities. A fund also could lose margin payments it has deposited with a margin broker if, for example, the broker became bankrupt. 
Most 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 the trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond the limit. However, the daily limit governs only price movement during a particular trading day and, therefore, does not limit potential losses. In addition, the daily limit may prevent 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
By purchasing an option on a futures contract, a fund obtains the right, but not the obligation, to sell the futures contract (a put option) or to buy the contract (a call option) at a fixed strike price. A fund can terminate its position in a put option by allowing it to expire or by exercising the option. If the option is exercised, a fund completes the sale of the underlying security at the strike price. Purchasing an option on a futures contract does not require a fund to make margin payments unless the option is exercised. 
Correlation of Price Changes
Because there are a limited number of types of exchange-traded futures and options contracts, it is likely that the standardized contracts available will not match a fund’s current or anticipated investments exactly. A fund may invest in futures and options contracts based on securities with different issuers, maturities, or other characteristics from the securities in which it typically invests (for example, by hedging intermediate-term securities with a futures contract based on an index of long-term bond prices); this involves a risk that the futures position will not track the performance of a fund’s other investments. 
Options and futures prices can diverge from the prices of their underlying instruments even if the underlying instruments correlate well with a fund’s investments. Options and futures prices are affected by factors such as current and anticipated short-term interest rates, changes in volatility of the underlying instrument, and the time remaining until expiration of the contract, which may not affect security prices the same way. Imperfect correlation also may result from differing levels of demand in the options and futures markets and securities markets, from structural differences in how options and futures and securities are traded, or from the imposition of daily price fluctuation limits or trading halts. A fund may purchase or sell options and futures contracts with a greater or lesser value than the securities it wishes to hedge or intends to purchase in an effort to compensate for differences in volatility between the contract and the securities, although this may not be successful in all cases. If price changes in a fund’s options or futures positions are poorly correlated with its other investments, the positions may fail to produce anticipated gains or result in losses that are not offset by gains in other investments.

Futures and Options Contracts Relating to Foreign Currencies 
A fund may purchase and sell currency futures and purchase and write currency options to increase or decrease its exposure to different foreign currencies. A fund also may purchase and write currency options in connection with currency futures or forward contracts. 
Currency futures contracts are similar to forward currency exchange contracts, except that they are traded on exchanges and have standard contract sizes and delivery dates. Most currency futures contracts call for payment or delivery in U.S. dollars. 
The uses and risks of currency futures are similar to those of futures relating to securities or indices, as described above. Currency futures values can be expected to correlate with exchange rates but may not reflect other factors that affect the value of a fund’s investments. A currency hedge, for example, should protect a German-mark-denominated security from a decline in the German mark, but it will not protect a fund against a price decline resulting from a deterioration in the issuer’s creditworthiness.
Liquidity of Futures Contracts and Options 
There is no assurance that a liquid secondary market will exist for any particular futures contract or option at any particular time. Options may have relatively low trading volume and liquidity if their strike prices are not close to the underlying instrument’s current price. In addition, exchanges may establish daily price fluctuation limits for futures contracts and options and may halt trading if a contract’s price moves upward or downward more than the limit on a given day. On volatile trading days when the price fluctuation limit is reached or a trading halt is imposed, it may be impossible for a fund to enter into new positions or close out existing positions. If the secondary market for a contract was not liquid, because of price fluctuation limits or otherwise, prompt liquidation of unfavorable positions could be difficult or impossible, and a fund could be required to continue holding a position until delivery or expiration regardless of changes in its value. Under these circumstances, a fund’s access to assets held to cover its future positions also could be impaired. 
Futures and options trading on foreign exchanges may not be regulated as effectively as similar transactions in the U.S. and may not involve clearing mechanisms or guarantees similar to those available in the U.S. The value of a futures contract or option traded on a foreign exchange may be adversely affected by the imposition of different exercise and settlement terms, trading procedures, margin requirements and lesser trading volume. 
Restrictions on the Use of Futures Contracts and Options 
Each fund may enter into futures contracts, options, options on futures contracts, or swap agreements as permitted by its investment policies and the Commodity Futures Trading Commission (CFTC) rules. The advisor to each fund has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act and, therefore, the advisor is not subject to registration or regulation as a commodity pool operator under that Act with respect to its provision of services to each fund. 
Certain rules adopted by the CFTC may impose additional limits on the ability of a fund to invest in futures contracts, options on futures, swaps, and certain other commodity interests if its investment advisor does not register with the CFTC as a “commodity pool operator” with respect to such fund. It is expected that the funds will be able to execute their investment strategies within the limits adopted by the CFTC’s rules. As a result, the advisor does not intend to register with the CFTC as a commodity pool operator on behalf of any of the funds. In the event that one of the funds engages in transactions that necessitate future registration with the CFTC, the advisor will register as a commodity pool operator and comply with applicable regulations with respect to that fund. 
To the extent required by law, each fund will segregate cash, cash equivalents or other appropriate liquid securities on its records in an amount sufficient to cover its obligations under the futures contracts, options and swap agreements.
Hybrid Securities
Hybrid securities have characteristics that differ from both common stocks and senior debt securities, typically ranking senior to common stock and subordinate to senior debt in an issuer’s capital structure. Hybrid securities may have features such as deferrable and/or non-cumulative interest payments, long-dated maturity or no maturity, reduced or no acceleration rights, and may be subject to principal reduction without default under certain circumstances. Because of these features, the managers may consider some hybrid securities to be equity or equity equivalents and some to be debt securities based on each security’s individual characteristics.
Inflation-Linked Securities
The funds may purchase inflation-linked securities issued by the U.S. Treasury, U.S. government agencies and instrumentalities other than the U.S. Treasury, and other entities, including those issued by governments of other countries and other foreign entities, including foreign issuers from emerging markets.
Inflation-linked securities are designed to offer a return linked to inflation, thereby protecting future purchasing power of the money invested in them. However, inflation-linked securities provide this protected return only if held to maturity. In addition, inflation-linked securities may not trade at par value. Real interest rates (the market rate of interest less the anticipated rate of inflation) change over time as a result of many factors, such as what investors are demanding as a true value for money. When real rates do change, inflation-linked securities prices will be more sensitive to these changes than conventional bonds, because these securities were sold originally based upon a real interest rate that is no longer prevailing. Should market expectations for real interest rates rise, the price of
18


inflation-linked securities and the share price of a fund holding these securities will fall. Investors in the funds should be prepared to accept not only this share price volatility but also the possible adverse tax consequences it may cause.
An investment in securities featuring inflation-adjusted principal and/or interest involves factors not associated with more traditional fixed-principal securities. Such factors include the possibility that the inflation index may be subject to significant changes, that changes in the index may or may not correlate to changes in interest rates generally or changes in other indices, or that the resulting interest may be greater or less than that payable on other securities of similar maturities. In the event of sustained deflation, it is possible that the amount of semiannual interest payments, the inflation-adjusted principal of the security or the value of the stripped components will decrease. If any of these possibilities are realized, a fund’s net asset value could be negatively affected.
Inflation-Linked Treasury Securities
Inflation-linked U.S. Treasury securities are U.S. Treasury securities with a final value and interest payment stream linked to the inflation rate. Inflation-linked U.S. Treasury securities may be issued in either note or bond form. Inflation-linked U.S. Treasury notes have maturities of at least one year, but not more than 10 years. Inflation-linked U.S. Treasury bonds have maturities of more than 10 years.
Inflation-linked U.S. Treasury securities may be attractive to investors seeking an investment backed by the full faith and credit of the U.S. government that provides a return in excess of the rate of inflation. These securities were first sold in the U.S. market in January 1997. Inflation-linked U.S. Treasury securities are auctioned and issued on a quarterly basis. 
Structure and Inflation Index – The principal value of inflation-linked U.S. Treasury securities will be adjusted to reflect changes in the level of inflation. The index for measuring the inflation rate for inflation-linked U.S. Treasury securities is the non-seasonally adjusted U.S. City Average All Items Consumer Price Index for All Urban Consumers (Consumer Price Index) published monthly by the U.S. Department of Labor’s Bureau of Labor Statistics.
Semiannual coupon interest payments are made at a fixed percentage of the inflation-linked principal value. The coupon rate for the semiannual interest rate of each issuance of inflation-linked U.S. Treasury securities is determined at the time the securities are sold to the public (i.e., by competitive bids in the auction). The coupon rate will likely reflect real yields available in the U.S. Treasury market; real yields are the prevailing yields on U.S. Treasury securities with similar maturities, less then-prevailing inflation expectations. While a reduction in inflation will cause a reduction in the interest payment made on the securities, the repayment of principal at the maturity of the security is guaranteed by the U.S. Treasury to be no less than the original face or par amount of the security at the time of issuance.
Indexing Methodology - The principal value of inflation-linked U.S. Treasury securities will be indexed, or adjusted, to account for changes in the Consumer Price Index. Semiannual coupon interest payment amounts will be determined by multiplying the inflation-linked principal amount by one-half the stated rate of interest on each interest payment date.
Taxation - The taxation of inflation-linked U.S. Treasury securities is similar to the taxation of conventional bonds. Both interest payments and the difference between original principal and the inflation-adjusted principal will be treated as interest income subject to taxation. Interest payments are taxable when received or accrued. The inflation adjustment to the principal is subject to tax in the year the adjustment is made, not at maturity of the security when the cash from the repayment of principal is received. If an upward adjustment has been made, investors in non-tax-deferred accounts will pay taxes on this amount currently. Decreases in the indexed principal can be deducted only from current or previous interest payments reported as income.
Inflation-linked U.S. Treasury securities therefore have a potential cash flow mismatch to an investor, because investors must pay taxes on the inflation-adjusted principal before the repayment of principal is received. It is possible that, particularly for high income tax bracket investors, inflation-linked U.S. Treasury securities would not generate enough cash in a given year to cover the tax liability they could create. This is similar to the current tax treatment for zero-coupon bonds and other discount securities. If inflation-linked U.S. Treasury securities are sold prior to maturity, capital losses or gains are realized in the same manner as traditional bonds. 
Investors in a fund will receive dividends that represent both the interest payments and the principal adjustments of the inflation-linked securities held in the fund’s portfolio. An investment in a fund may, therefore, be a means to avoid the cash flow mismatch associated with a direct investment in inflation-linked securities. For more information about taxes and their effect on you as an investor in the funds, see Taxes, page 52.
U.S. Government Agencies
A number of U.S. government agencies and instrumentalities other than the U.S. Treasury may issue inflation-linked securities. Some U.S. government agencies have issued inflation-linked securities whose design mirrors that of the inflation-linked U.S. Treasury securities described above.
Other/Foreign Entities
Entities other than the U.S. Treasury or U.S. government agencies and instrumentalities may issue inflation-linked securities. While some entities have issued inflation-linked securities whose design mirrors that of the inflation-linked U.S. Treasury securities described above, others utilize different structures. For example, the principal value of these securities may be adjusted with reference to the Consumer Price Index, but the semiannual coupon interest payments are made at a fixed percentage of the original issue
19


principal. Alternatively, the principal value may remain fixed, but the coupon interest payments may be adjusted with reference to the Consumer Price Index.
Inflation-linked securities issued by a foreign government are generally adjusted to reflect an index comparable to the U.S.’s CPI index, as calculated by such foreign government. There can be no assurance that the foreign inflation index will accurately measure the real rate of inflation in the prices of goods and services. Moreover, there can be no assurance that the rate of inflation in a foreign country will be correlated to the rate of inflation in the U.S. In addition, to the extent that the currency used to calculate the fund’s NAV is different from the currencies of the underlying inflation-linked securities held by the fund, changes in foreign exchange rates may negate the impact of any adjustments to interest rates payable on inflation-linked securities when the fund’s NAV is calculated. As inflation generally has the effect of diluting the value of a given currency against other currencies, any increase in the value of the fund attributable to increased interest income resulting from an adjustment to the interest rate of an inflation-linked security may be lost through a decrease in value of the underlying bond when its value is translated into U.S. dollars. 
Inverse Floaters
Emerging Markets Debt and International Bond may hold inverse floaters. An inverse floater is a type of derivative security that bears an interest rate that moves inversely to market interest rates. As market interest rates rise, the interest rate on inverse floaters goes down, and vice versa. Generally, this is accomplished by expressing the interest rate on the inverse floater as an above-market fixed rate of interest, reduced by an amount determined by reference to a market-based or bond-specific floating interest rate (as well as by any fees associated with administering the inverse floater program).
Inverse floaters may be issued in conjunction with an equal amount of Dutch Auction floating-rate bonds (floaters), or a market-based index may be used to set the interest rate on these securities. A Dutch Auction is an auction system in which the price of the security is gradually lowered until it meets a responsive bid and is sold. Floaters and inverse floaters may be brought to market by (1) a broker-dealer who purchases fixed-rate bonds and places them in a trust, or (2) an issuer seeking to reduce interest expenses by using a floater/inverse floater structure in lieu of fixed-rate bonds.
In the case of a broker-dealer structured offering (where underlying fixed-rate bonds have been placed in a trust), distributions from the underlying bonds are allocated to floater and inverse floater holders in the following manner:
(i)Floater holders receive interest based on rates set at a six-month interval or at a Dutch Auction, which is typically held every 28 to 35 days. Current and prospective floater holders bid the minimum interest rate that they are willing to accept on the floaters, and the interest rate is set just high enough to ensure that all of the floaters are sold.
(ii)Inverse floater holders receive all of the interest that remains, if any, on the underlying bonds after floater interest and auction fees are paid. The interest rates on inverse floaters may be significantly reduced, even to zero, if interest rates rise.
Procedures for determining the interest payment on floaters and inverse floaters brought to market directly by the issuer are comparable, although the interest paid on the inverse floaters is based on a presumed coupon rate that would have been required to bring fixed-rate bonds to market at the time the floaters and inverse floaters were issued. 
Where inverse floaters are issued in conjunction with floaters, inverse floater holders may be given the right to acquire the underlying security (or to create a fixed-rate bond) by calling an equal amount of corresponding floaters. The underlying security may then be held or sold. However, typically, there are time constraints and other limitations associated with any right to combine interests and claim the underlying security.
Floater holders subject to a Dutch Auction procedure generally do not have the right to put back their interests to the issuer or to a third party. If a Dutch Auction fails, the floater holder may be required to hold its position until the underlying bond matures, during which time interest on the floater is capped at a predetermined rate. 
The secondary market for floaters and inverse floaters may be limited. The market value of inverse floaters tends to be significantly more volatile than fixed-rate bonds.
LIBOR Transition Risk
The London Interbank Offered Rate (“LIBOR”) is a benchmark interest rate intended to be representative of the rate at which major international banks who are members of the British Bankers Association lend to one another over short-terms. Following manipulation allegations, financial institutions have started the process of phasing out the use of LIBOR. The transition process to a replacement rate or rates may also result in a change in the value of certain instruments the funds hold or a change in the cost of temporary borrowing for the funds. As LIBOR is discontinued, the LIBOR replacement rate may be lower than market expectations, which could have an adverse impact on the value of preferred and debt-securities with floating or fixed-to-floating rate coupons. The transition away from LIBOR could result in losses to the funds.
Loan Participation Notes
In terms of their functioning and investment risk, loan participation notes (“LPNs”) are comparable to an investment in “normal” bonds. In return for the investor’s commitment of capital, the issuer makes regular interest payments and, at maturity or in accordance with an agreed upon amortization schedule, the note is repaid at par.
20


However, in contrast to “normal” bonds, there are three parties involved in the issuance of an LPN. The legal issuer, typically a bankruptcy-remote, limited purpose entity, issues notes to investors and uses the proceeds received from investors to make loans to the borrower—with each loan generally having substantially identical payment terms to the related note issued by the issuer. The borrower is typically an operating company, and the issuer’s obligations under a note are typically limited to the extent of any capital repayments and interest payments made by the borrower under the related loan. Accordingly, the investor generally assumes the credit risk of the underlying borrower. The loan participation note structure is generally used to provide the borrower more efficient financing in the capital markets than the borrower would be able to obtain if it issued notes directly.
In the event of a default by the borrower of an LPN, the fund may experience delays in receiving payments of interest and principal while the note issuer enforces and liquidates the underlying collateral, and there is no guarantee that the underlying collateral will cover the principal and interest owed to the fund under the LPN.
LPNs are generally subject to liquidity risk. Even though an LPN may be traded on an exchange there can be no assurance that a liquid market will develop for the LPNs, that holders of the LPNs will be able to sell their LPNs, or that such holders will be able to sell their LPNs for a price that reflects their value.
Depending on the creditworthiness of the underlying borrower, LPNs may be subject to the risk of investing in high-yield securities. Additionally, LPNs are generally utilized by foreign borrowers and therefore may be subject to the risk of investing in foreign securities and emerging markets risk. Such foreign risk could include interest payments being subject to withholding tax. 
Loan Participations
Emerging Markets Debt may purchase loan participations, which represent interests in the cash flow generated by commercial loans. Each loan participation requires three parties: a participant (or investor), a lending bank and a borrower. The investor purchases a share in a loan originated by a lending bank, and this participation entitles the investor to a percentage of the principal and interest payments made by the borrower.
Loan participations are attractive because they typically offer higher yields than other money market instruments. However, along with these higher yields come certain risks, not the least of which is the risk that the borrower will be unable to repay the loan. Generally, because the lending bank does not guarantee payment, the investor is directly exposed to risk of default by the borrower. In addition, the investor is not a direct creditor of the borrower. The participation represents an interest in assets owned by the lending bank. If the lending bank becomes insolvent, the investor could be considered an unsecured creditor of the bank instead of the holder of a participating interest in a loan. Because of these risks, the manager must carefully consider the creditworthiness of both the borrower and the lender.
Another concern is liquidity. Because there is no established secondary market for loan participations, a fund’s ability to sell them for cash is limited. Some participation agreements place limitations on the investor’s right to resell the loan participation, even when a buyer can be found. 
Loans of Portfolio Securities
In order to realize additional income, a fund may lend its portfolio securities. Such loans may not exceed one-third of a fund’s total assets valued at market, however, this limitation does not apply to purchases of debt securities in accordance with a fund’s investment objectives, policies and limitations, or to repurchase agreements with respect to portfolio securities. 
Cash received from the borrower as collateral through loan transactions may be invested in other eligible securities. Investing this cash subjects that investment to market appreciation or depreciation. If a borrower defaults on a securities loan because of insolvency or other reasons, the lending fund could experience delays or costs in recovering the securities it loaned; if the value of the loaned securities increased over the value of the collateral, a fund could suffer a loss. To minimize the risk of default on securities loans, the advisor adheres to guidelines prescribed by the Board of Trustees governing lending of securities. These guidelines strictly govern:
the type and amount of collateral that must be received by the fund;
the circumstances under which additions to that collateral must be made by borrowers;
the return to be received by the fund on the loaned securities;
the limitations on the percentage of fund assets on loan; and
the credit standards applied in evaluating potential borrowers of portfolio securities.
In addition, the guidelines require that the fund have the option to terminate any loan of a portfolio security at any time and set requirements for recovery of securities from borrowers.
Mortgage-Related Securities
To the extent permitted by its investment objective, a fund may invest in mortgage-related securities.
Background
A mortgage-backed security represents an ownership interest in a pool of mortgage loans. The loans are made by financial institutions to finance home and other real estate purchases. As the loans are repaid, investors receive payments of both interest and principal.
21


Like fixed-income securities, mortgage-backed securities pay a stated rate of interest during the life of the security. However, unlike a bond, which returns principal to the investor in one lump sum at maturity, mortgage-backed securities return principal to the investor in increments during the life of the security.
Because the timing and speed of principal repayments vary, the cash flow on mortgage-backed securities is irregular. If mortgage holders sell their homes, refinance their loans, prepay their mortgages or default on their loans, the principal is distributed pro rata to investors.
As with other fixed-income securities, the prices of mortgage-backed securities fluctuate in response to changing interest rates; when interest rates fall, the prices of mortgage-backed securities rise, and vice versa. Changing interest rates have additional significance for mortgage-backed securities investors, however, because they influence prepayment rates (the rates at which mortgage holders prepay their mortgages), which in turn affect the yields on mortgage-backed securities. When interest rates decline, prepayment rates generally increase. Mortgage holders take advantage of the opportunity to refinance their mortgages at lower rates with lower monthly payments. When interest rates rise, mortgage holders are less inclined to refinance their mortgages. The effect of prepayment activity on yield depends on whether the mortgage-backed security was purchased at a premium or at a discount. 
A fund may receive principal sooner than it expected because of accelerated prepayments. Under these circumstances, a fund might have to reinvest returned principal at rates lower than it would have earned if principal payments were made on schedule. Conversely, a mortgage-backed security may exceed its anticipated life if prepayment rates decelerate unexpectedly. Under these circumstances, the fund might miss an opportunity to earn interest at higher prevailing rates. 
A fund may invest in covered bonds or covered mortgages. Covered bonds are securities issued by a bank and backed by a dedicated group of loans known as a cover pool.
Collateralized Mortgage Obligations (CMOs)
A CMO is a multiclass bond backed by a pool of mortgage pass-through certificates or mortgage loans. In structuring a CMO, an issuer distributes cash flow from the underlying collateral over a series of classes called tranches. Each CMO is a set of two or more tranches, with average lives and cash flow patterns designed to meet specific investment objectives. The average life expectancies of the different tranches in a four-part deal, for example, might be two, five, seven and 20 years.
As payments on the underlying mortgage loans are collected, the CMO issuer pays the coupon rate of interest to the bondholders in each tranche. At the outset, scheduled and unscheduled principal payments go to investors in the first tranches. Investors in later tranches do not begin receiving principal payments until the prior tranches are paid off. This basic type of CMO is known as a sequential pay or plain vanilla CMO. 
Some CMOs are structured so that the prepayment or market risks are transferred from one tranche to another. Prepayment stability is improved in some tranches if other tranches absorb more prepayment variability.
The final tranche of a CMO often takes the form of a Z-bond, also known as an accrual bond or accretion bond. Holders of these securities receive no cash until the earlier tranches are paid in full. During the period that the other tranches are outstanding, periodic interest payments are added to the initial face amount of the Z-bond but are not paid to investors. When the prior tranches are retired, the Z-bond receives coupon payments on its higher principal balance plus any principal prepayments from the underlying mortgage loans. The existence of a Z-bond tranche helps stabilize cash flow patterns in the other tranches. In a changing interest rate environment, however, the value of the Z-bond tends to be more volatile. 
As CMOs have evolved, some classes of CMO bonds have become more prevalent. The planned amortization class (PAC) and targeted amortization class (TAC), for example, were designed to reduce prepayment risk by establishing a sinking-fund structure. PAC and TAC bonds assure to varying degrees that investors will receive payments over a predetermined period under various prepayment scenarios. Although PAC and TAC bonds are similar, PAC bonds are better able to provide stable cash flows under various prepayment scenarios than TAC bonds because of the order in which these tranches are paid. 
The existence of a PAC or TAC tranche can create higher levels of risk for other tranches in the CMO because the stability of the PAC or TAC tranche is achieved by creating at least one other tranche—known as a companion bond, support or non-PAC bond—that absorbs the variability of principal cash flows. Because companion bonds have a high degree of average life variability, they generally pay a higher yield. A TAC bond can have some of the prepayment variability of a companion bond if there is also a PAC bond in the CMO issue.
Floating-rate CMO tranches (floaters) pay a variable rate of interest. Institutional investors with short-term liabilities, such as commercial banks, often find floating-rate CMOs attractive investments. Super floaters and inverse floaters are variations on the floater structure that have highly variable cash flows.
Commercial Mortgage-Backed Securities (CMBS)
CMBS are securities created from a pool of commercial mortgage loans, such as loans for hotels, shopping centers, office buildings, apartment buildings, and the like. Interest and principal payments from these loans are passed on to the investor according to a particular schedule of payments. The credit quality of CMBS depends primarily on the quality of the underlying loans and on the structure of the particular deal. Generally, deals are structured with senior and subordinate classes. Multiple classes may permit the issuance of securities with payment terms, interest rates, or other characteristics differing both from those of each other and those of
22


the underlying assets. Examples include classes having characteristics such as floating interest rates or scheduled amortization of principal. Rating agencies rate the individual classes of the deal based on the degree of seniority or subordination of a particular class and other factors. The value of these securities may change because of actual or perceived changes in the creditworthiness of individual borrowers, their tenants, the servicing agents, or the general state of commercial real estate and other factors.
CMBS may be partially stripped so that each investor class receives some interest and some principal. When securities are completely stripped, however, all of the interest is distributed to holders of one type of security, known as an interest-only security (IO), and all of the principal is distributed to holders of another type of security known as a principal-only security (PO). The funds are permitted to invest in IO classes of CMBS. As interest rates rise and fall, the value of IOs tends to move in the same direction as interest rates. The cash flows and yields on IO classes are extremely sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets. In the cases of IOs, prepayments affect the amount of cash flows provided to the investor. If the underlying mortgage assets experience greater than anticipated prepayments of principal, an investor may fail to fully recoup its initial investment in an IO class of a stripped mortgage-backed security, even if the IO class is rated AAA or Aaa or is derived from a full faith and credit obligation. However, because commercial mortgages are often locked out from prepayment, or have high prepayment penalties or a defeasance mechanism, the prepayment risk associated with a CMBS IO class is generally less than that of a residential IO.
Adjustable Rate Mortgage Securities
Adjustable rate mortgage securities (ARMs) have interest rates that reset at periodic intervals. Acquiring ARMs permits a fund to participate in increases in prevailing current interest rates through periodic adjustments in the coupons of mortgages underlying the pool on which ARMs are based. In addition, when prepayments of principal are made on the underlying mortgages during periods of rising interest rates, a fund can reinvest the proceeds of such prepayments at rates higher than those at which they were previously invested. Mortgages underlying most ARMs, however, have limits on the allowable annual or lifetime increases that can be made in the interest rate that the mortgagor pays. Therefore, if current interest rates rise above such limits over the period of the limitation, a fund holding an ARM does not benefit from further increases in interest rates. Moreover, when interest rates are in excess of coupon rates (i.e., the rates being paid by mortgagors) of the mortgages, ARMs behave more like fixed income securities and less like adjustable rate securities and are subject to the risks associated with fixed income securities. In addition, during periods of rising interest rates, increases in the coupon rate of adjustable rate mortgages generally lag current market interest rates slightly, thereby creating the potential for capital depreciation on such securities. 
GNMA Certificates
The Government National Mortgage Association (GNMA) is a wholly owned corporate instrumentality of the United States within the Department of Housing and Urban Development. The National Housing Act of 1934 (Housing Act), as amended, authorizes GNMA to guarantee the timely payment of interest and repayment of principal on certificates that are backed by a pool of mortgage loans insured by the Federal Housing Administration under the Housing Act, or by Title V of the Housing Act of 1949 (FHA Loans), or guaranteed by the Department of Veterans Affairs under the Servicemen’s Readjustment Act of 1944 (VA Loans), as amended, or by pools of other eligible mortgage loans. The Housing Act provides that the full faith and credit of the U.S. government is pledged to the payment of all amounts that may be required to be paid under any guarantee. GNMA has unlimited authority to borrow from the U.S. Treasury in order to meet its obligations under this guarantee.
GNMA certificates represent a pro rata interest in one or more pools of the following types of mortgage loans: (a) fixed-rate level payment mortgage loans; (b) fixed-rate graduated payment mortgage loans (GPMs); (c) fixed-rate growing equity mortgage loans (GEMs); (d) fixed-rate mortgage loans secured by manufactured (mobile) homes (MHs); (e) mortgage loans on multifamily residential properties under construction (CLCs); (f) mortgage loans on completed multifamily projects (PLCs); (g) fixed-rate mortgage loans that use escrowed funds to reduce the borrower’s monthly payments during the early years of the mortgage loans (buydown mortgage loans); and (h) mortgage loans that provide for payment adjustments based on periodic changes in interest rates or in other payment terms of the mortgage loans.
Fannie Mae Certificates
The Federal National Mortgage Association (FNMA or Fannie Mae) is a federally chartered and privately owned corporation established under the Federal National Mortgage Association Charter Act. Fannie Mae was originally established in 1938 as a U.S. government agency designed to provide supplemental liquidity to the mortgage market and was reorganized as a stockholder-owned and privately managed corporation by legislation enacted in 1968. Fannie Mae acquires capital from investors who would not ordinarily invest in mortgage loans directly and thereby expands the total amount of funds available for housing. This money is used to buy home mortgage loans from local lenders, replenishing the supply of capital available for mortgage lending.
Fannie Mae certificates represent a pro rata interest in one or more pools of FHA Loans, VA Loans, or, most commonly, conventional mortgage loans (i.e., mortgage loans that are not insured or guaranteed by a government agency) of the following types: (a) fixed-rate level payment mortgage loans; (b) fixed-rate growing equity mortgage loans; (c) fixed-rate graduated payment mortgage loans; (d) adjustable-rate mortgage loans; and (e) fixed-rate mortgage loans secured by multifamily projects.
Fannie Mae certificates entitle the registered holder to receive amounts representing a pro rata interest in scheduled principal and interest payments (at the certificate’s pass-through rate, which is net of any servicing and guarantee fees on the underlying mortgage
23


loans), any principal prepayments, and a proportionate interest in the full principal amount of any foreclosed or otherwise liquidated mortgage loan. The full and timely payment of interest and repayment of principal on each Fannie Mae certificate is guaranteed by Fannie Mae; this guarantee is not backed by the full faith and credit of the U.S. government. See Current Status of Fannie Mae and Freddie Mac below.
Freddie Mac Certificates
The Federal Home Loan Mortgage Corporation (FHLMC or Freddie Mac) is a corporate instrumentality of the United States created pursuant to the Emergency Home Finance Act of 1970 (FHLMC Act), as amended. Freddie Mac was established primarily for the purpose of increasing the availability of mortgage credit. Its principal activity consists of purchasing first-lien conventional residential mortgage loans (and participation interests in such mortgage loans) and reselling these loans in the form of mortgage-backed securities, primarily Freddie Mac certificates.
Freddie Mac certificates represent a pro rata interest in a group of mortgage loans (a Freddie Mac certificate group) purchased by Freddie Mac. The mortgage loans underlying Freddie Mac certificates consist of fixed- or adjustable-rate mortgage loans with original terms to maturity of between 10 and 30 years, substantially all of which are secured by first-liens on one- to four-family residential properties or multifamily projects. Each mortgage loan must meet standards set forth in the FHLMC Act. A Freddie Mac certificate group may include whole loans, participation interests in whole loans, undivided interests in whole loans, and participations composing another Freddie Mac certificate group.
Freddie Mac guarantees to each registered holder of a Freddie Mac certificate the timely payment of interest at the rate provided for by the certificate. Freddie Mac also guarantees ultimate collection of all principal on the related mortgage loans, without any offset or deduction, but generally does not guarantee the timely repayment of principal. Freddie Mac may remit principal at any time after default on an underlying mortgage loan, but no later than 30 days following (a) foreclosure sale, (b) payment of a claim by any mortgage insurer, or (c) the expiration of any right of redemption, whichever occurs later, and in any event no later than one year after demand has been made upon the mortgager for accelerated payment of principal. Obligations guaranteed by Freddie Mac are not backed by the full faith and credit pledge of the U.S. government. See Current Status of Fannie Mae and Freddie Mac below.
Current Status of Fannie Mae and Freddie Mac
Since September 2008, Fannie Mae and Freddie Mac have operated under a conservatorship administered by the Federal Housing Finance Agency (FHFA). In addition, the U.S. Treasury has entered into senior preferred stock purchase agreements (SPSPAs) to provide additional financing to Fannie Mae and Freddie Mac. Although the SPSPAs are intended to provide Fannie Mae and Freddie Mac with the necessary cash resources to meet their obligations, Fannie Mae and Freddie Mac continue to operate as going concerns while in conservatorship, and each remains liable for all of its obligations, including its guaranty obligations, associated with its mortgage-backed securities.
The future status and role of Fannie Mae or Freddie Mac could be impacted by, among other things, the actions taken and restrictions placed on Fannie Mae or Freddie Mac by the FHFA in its role as conservator, the restrictions placed on Fannie Mae’s or Freddie Mac’s operations and activities under the senior preferred stock purchase agreements, market responses to developments at Fannie Mae or Freddie Mac, and future legislative, regulatory, or legal action that alters the operations, ownership, structure and/or mission of Fannie Mae or Freddie Mac, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Fannie Mae and Freddie Mac.
Stripped Mortgage-Backed Securities
Stripped mortgage-backed securities are created by segregating the cash flows from underlying mortgage loans or mortgage securities to create two or more new securities, each with a specified percentage of the underlying security’s principal or interest payments. Mortgage-backed securities may be partially stripped so that each investor class receives some interest and some principal. When securities are completely stripped, however, all of the interest is distributed to holders of one type of security, known as an interest-only security, or IO, and all of the principal is distributed to holders of another type of security known as a principal-only security, or PO. Strips can be created in a pass-through structure or as tranches of a CMO.
The market values of IOs and POs are very sensitive to interest rate and prepayment rate fluctuations. POs, for example, increase (or decrease) in value as interest rates decline (or rise). The price behavior of these securities also depends on whether the mortgage collateral was purchased at a premium or discount to its par value. Prepayments on discount coupon POs generally are much lower than prepayments on premium coupon POs. IOs may be used to hedge a fund’s other investments because prepayments cause the value of an IO strip to move in the opposite direction from other mortgage-backed securities.
To-Be-Announced Mortgage-Backed Securities
To-be-announced (TBA) commitments are forward agreements for the purchase or sale of securities, which are described in greater detail under the heading When-Issued and Forward Commitment Agreements. A fund may gain exposure to mortgage-backed securities through TBA transactions. TBA mortgage-backed securities typically are debt securities structured by agencies such as Fannie Mae and Freddie Mac. In a typical TBA mortgage transaction, certain terms (such as price) are fixed, with delayed payment and delivery on an agreed upon future settlement date. The specific mortgage-backed securities to be delivered are not typically identified at the trade date but the delivered security must meet specified terms (such as issuer, interest rate, and underlying mortgage
24


terms). Consequently, TBA mortgage-backed transactions involve increased interest rate risk because the underlying mortgages may be less favorable at delivery than anticipated. TBA mortgage contracts also involve a risk of loss if the value of the underlying security to be purchased declines prior to delivery date. The yield obtained for such securities may be higher or lower than yields available in the market on delivery date.
The funds may also take short positions in TBA investments. To enter a short sale of a TBA security, a fund effectively agrees to sell a security it does not own at a future date and price. The funds generally anticipate closing short TBA positions before delivery of the respective security is required, however if the fund is unable to close a position, the fund would have to purchase the securities needed to settle the short sale. Such purchases could be at a different price than anticipated, and the fund would lose or gain money based on the acquisition price.
Municipal Obligations
The funds may invest in tax-exempt or taxable municipal obligations, which are generally issued by state and local governments or government entities. Interest payments from municipal obligations are generally exempt from federal income tax. Interest payments from certain municipal obligations, however, are subject to federal income tax because of the degree of non-government involvement in the transaction or because federal tax code limitations on the issuance of tax-exempt bonds that benefit private entities have been exceeded. Some typical examples of these taxable municipal obligations include industrial revenue bonds and economic development bonds issued by state or local governments to aid private enterprise. The interest on a taxable municipal bond is often exempt from state taxation in the issuing state. The funds do not expect to be eligible to pass through to shareholders the tax-exempt character of interest on municipal obligations.
Other Investment Companies 
A fund may invest in other investment companies, such as closed-end investment companies, unit investment trusts, exchange-traded funds (ETFs) and other open-end investment companies, provided that the investment is consistent with a fund’s investment policies and restrictions. Under the Investment Company Act, a fund’s investment in such securities, subject to certain exceptions, currently is limited to
3% of the total voting stock of any one investment company
5% of the fund’s total assets with respect to any one investment company and
10% of the fund’s total assets in the aggregate.
Such exceptions may include reliance on Rule 12d1-4 of the Investment Company Act. Rule 12d1-4, subject to certain requirements, would permit a fund to invest in affiliated investment companies (other American Century mutual funds and ETFs) and unaffiliated investment companies in excess of the limitations described above.
A fund’s investments in other investment companies may include money market funds managed by the advisor. Investments in money market funds are not subject to the percentage limitations set forth above.
As a shareholder of another investment company, a fund would bear, along with other shareholders, its pro rata portion of the other investment company’s expenses, including advisory fees. These expenses would be in addition to the management fee that each fund bears directly in connection with its own operations. 
ETFs are a type of fund bought and sold on a securities exchange. An ETF trades like common stock and may be actively managed or index-based. A fund may purchase an ETF to temporarily gain exposure to a portion of the U.S. or a foreign market while awaiting purchase of underlying securities, to gain exposure to specific asset classes or sectors, or as a substitute for investing directly in securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities. Additionally, because the price of ETF shares is based on market price rather than net asset value (NAV), shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). A fund may also incur brokerage commissions, as well as the cost of the bid/ask spread, when purchasing or selling ETF shares.
Repurchase Agreements
Each fund may invest in repurchase agreements when they present an attractive short-term return on cash that is not otherwise committed to the purchase of securities pursuant to the investment policies of the fund.
A repurchase agreement occurs when, at the time a fund purchases an interest-bearing obligation, the seller (a bank or a broker-dealer registered under the Securities Exchange Act of 1934) agrees to purchase it on a specified date in the future at an agreed-upon price. The repurchase price reflects an agreed-upon interest rate during the time a fund’s money is invested in the security.
Because the security purchased constitutes collateral for the repurchase obligation, a repurchase agreement can be considered a loan collateralized by the security purchased. A fund’s risk is the seller’s ability to pay the agreed-upon repurchase price on the repurchase date. If the seller defaults, a fund may incur costs in disposing of the collateral, which would reduce the amount realized thereon. If the seller seeks relief under the bankruptcy laws, the disposition of the collateral may be delayed or limited. To the extent the value of the security decreases, a fund could experience a loss.
25


Each fund will limit repurchase agreement transactions to securities issued by the U.S. government and its agencies and instrumentalities, and will enter into such transactions with those banks and securities dealers who are deemed creditworthy pursuant to criteria adopted by the funds’ advisor. 
Repurchase agreements maturing in more than seven days would count toward a fund’s 15% limit on illiquid securities.
Short-Term Securities
In order to meet anticipated redemptions, anticipated purchases of additional securities for a fund’s portfolio, or, in some cases, for temporary defensive purposes, each fund may invest a portion of its assets in money market and other short-term securities.
Examples of those securities include:
Securities issued or guaranteed by the U.S. government and its agencies and instrumentalities;
Commercial Paper;
Certificates of Deposit and Euro Dollar Certificates of Deposit;
Bankers’ Acceptances;
Short-term notes, bonds, debentures or other debt instruments;
Repurchase agreements; and
Money market funds.
Swap Agreements 
Each fund may invest in swap agreements, consistent with its investment objective and strategies. A fund may enter into a swap agreement in order to, for example, attempt 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; protect against currency fluctuations; attempt to manage duration to protect against any increase in the price of securities a fund anticipates purchasing at a later date; or gain exposure to certain markets in the most economical way possible.
Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or “swapped” between the parties are generally calculated with respect to a “notional amount,” i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a “basket” of securities representing a particular index. Forms of swap agreements include, for example, interest rate swaps, under which fixed- or floating-rate interest payments on a specific principal amount are exchanged and total return swaps, under which one party agrees to pay the other the total return of a defined underlying asset (usually an index, including inflation indexes, stock, bond or defined portfolio of loans and mortgages) in exchange for fee payments, often a variable stream of cash flows based on a reference rate. A fund may enter into credit default swap agreements to hedge an existing position by purchasing or selling credit protection. Credit default swaps enable an investor to buy/sell protection against a credit event of a specific issuer. The seller of credit protection against a security or basket of securities receives an up-front or periodic payment to compensate against potential default event(s). A fund may enhance returns by selling protection or attempt to mitigate credit risk by buying protection. Market supply and demand factors may cause distortions between the cash securities market and the credit default swap market. 
Whether a fund’s use of swap agreements will be successful depends on the advisor’s ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments. Interest rate swaps could result in losses if interest rate changes are not correctly anticipated by the fund. Total return swaps could result in losses if the reference index, security, or investments do not perform as anticipated by the fund. Credit default swaps could result in losses if the fund does not correctly evaluate the creditworthiness of the issuer on which the credit default swap is based. Because they are two-party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, a fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. The funds will enter into swap agreements only with counterparties that meet certain standards of creditworthiness or that are cleared through a Derivatives Clearing Organization (“DCO”). Certain restrictions imposed on the funds by the Internal Revenue Code may limit the funds’ ability to use swap agreements.
The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and related regulatory developments require the clearing and exchange-trading of certain standardized derivative instruments that the CFTC and SEC have defined as “swaps.” The CFTC has implemented mandatory exchange-trading and clearing requirements under the Dodd-Frank Act and the CFTC continues to approve contracts for central clearing. Although exchange trading is designed to decrease counterparty risk, it does not do so entirely because the fund will still be subject to the credit risk of the central clearinghouse. Cleared swaps are subject to margin requirements imposed by both the central clearinghouse and the clearing member FCM. Uncleared swaps are now subject to posting and collecting collateral on a daily basis to secure mark-to-market obligations (variation margin). Swaps data reporting may subject a fund to administrative costs, and the safeguards established to protect trader anonymity
26


may not function as expected. Exchange trading, central clearing, margin requirements, and data reporting regulations may increase a fund’s cost of hedging risk and, as a result, may affect shareholder returns.
U.S. Government Securities
Each fund may invest in U.S. government securities including bills, notes and bonds issued by the U.S. Treasury and securities issued or guaranteed by agencies or instrumentalities of the U.S. government. 
Some U.S. government securities are supported by the direct full faith and credit of the U.S. government; others are supported by the right of the issuer to borrow from the U.S. Treasury; others, such as securities issued by the Federal National Mortgage Association (FNMA), are supported by the discretionary authority of the U.S. government to purchase the agencies’ obligations; and others are supported only by the credit of the issuing or guaranteeing instrumentality. There is no assurance that the U.S. government will provide financial support to an instrumentality it sponsors when it is not obligated by law to do so. 
Variable- and Floating-Rate Securities
Variable- and floating-rate securities, including variable-rate demand obligations (VRDOs) and floating-rate notes (FRNs), provide for periodic adjustments to the interest rate. The adjustments are generally based on an index-linked formula, or determined through a remarketing process.
These types of securities may be combined with a put or demand feature that permits the fund to demand payment of principal plus accrued interest from the issuer or a financial institution. Examples of VRDOs include variable-rate demand note (VRDN) and variable-rate demand preferreds (VRDP). VRDNs combine a demand feature with an interest rate reset mechanism designed to result in a market value for the security that approximates par. VRDNs are generally designed to meet the requirements of money market fund Rule 2a-7. VRDPs are issued by a closed-end fund that in turn invests primarily in portfolios of bonds. They feature a floating rate dividend set via a weekly remarketing and have a fixed term, mandatory redemption, and an unconditional par put option.
When-Issued and Forward Commitment Agreements
Each fund may sometimes purchase new issues of securities on a when-issued or forward commitment basis in which the transaction price and yield are each fixed at the time the commitment is made, but payment and delivery occur at a future date.
For example, a fund may sell a security and at the same time make a commitment to purchase the same or a comparable security at a future date and specified price. Conversely, a fund may purchase a security and at the same time make a commitment to sell the same or a comparable security at a future date and specified price. These types of transactions are executed simultaneously in what are known as dollar-rolls, buy/sell back transactions, cash and carry, or financing transactions. For example, a broker-dealer may seek to purchase a particular security that a fund owns. A fund will sell that security to the broker-dealer and simultaneously enter into a forward commitment agreement to buy it back at a future date. This type of transaction generates income for the fund if the dealer is willing to execute the transaction at a favorable price in order to acquire a specific security.
When purchasing securities on a when-issued or forward commitment basis, a fund assumes the rights and risks of ownership, including the risks of price and yield fluctuations. Market rates of interest on debt securities at the time of delivery may be higher or lower than those contracted for on the when-issued security. Accordingly, the value of the security may decline prior to delivery, which could result in a loss to a fund. While a fund will make commitments to purchase or sell securities with the intention of actually receiving or delivering them, it may sell the securities before the settlement date if doing so is deemed advisable as a matter of investment strategy.
To the extent a fund remains fully invested or almost fully invested at the same time it has purchased securities on a when-issued basis, there will be greater fluctuations in its net asset value than if it solely set aside cash to pay for when-issued securities. When the time comes to pay for the when-issued securities, a fund will meet its obligations with available cash, through the sale of securities, or, although it would not normally expect to do so, by selling the when-issued securities themselves (which may have a market value greater or less than the fund’s payment obligation). Selling securities to meet when-issued or forward commitment obligations may generate taxable capital gains or losses.
Zero-Coupon, Step-Coupon, Range Floaters and Pay-In-Kind Securities
Emerging Markets Debt may purchase zero-coupon debt securities. Zero-coupon debt securities do not make regular cash interest payments, and are sold at a deep discount to their face value.
Each fund may also purchase step-coupon or step-rate debt securities. Instead of having a fixed coupon for the life of the security, coupon or interest payments may increase to predetermined rates at future dates. The issuer generally retains the right to call the security. Some step-coupon securities are issued with no coupon payments at all during an initial period, and only become interest-bearing at a future date; these securities are sold at a deep discount to their face value.
Finally, Emerging Markets Debt may purchase pay-in-kind securities that do not make regular cash interest payments, but pay interest through the issuance of additional securities. Because such securities do not pay current cash income, the price of these securities can be volatile when interest rates fluctuate.
27


Although zero-coupon, pay-in-kind and certain range floaters and step-coupon securities may not pay current cash income, federal income tax law requires the holder to include in income each year the portion of any original issue discount and other noncash income on such securities accrued during that year. In order to continue to qualify for treatment as a regulated investment company under the Internal Revenue Code and avoid certain excise tax, the funds are required to make distributions of any original issue discount and other noncash income accrued for each year. Accordingly, the funds may be required to dispose of other portfolio securities, which may occur in periods of adverse market prices, in order to generate a case to meet these distribution requirements. 
Investment Policies
Unless otherwise indicated, with the exception of the percentage limitations on borrowing, the policies described below apply at the time a fund enters into a transaction. Accordingly, any later increase or decrease beyond the specified limitation resulting from a change in a fund’s assets will not be considered in determining whether it has complied with its investment policies.
Fundamental Investment Policies
The funds’ fundamental investment policies are set forth below. These investment policies, a fund’s status as diversified, and the investment objective of Global Bond Fund, as set forth in the fund’s prospectus, may not be changed without approval of a majority of the outstanding votes of shareholders of the fund. Under the Investment Company Act, the vote of a majority of the outstanding votes of shareholders means, the vote of (A) 67 percent or more of the voting securities present at a shareholder meeting, if the holders of more than 50 percent of the outstanding voting securities are present or represented by proxy; or (B) more than 50 percent of the outstanding voting securities, whichever is less.
Subject Policy
Senior Securities A fund may not issue senior securities, except as permitted under the Investment Company Act.
Borrowing A fund may not borrow money, except that a fund may borrow for temporary or emergency purposes (not for leveraging or investment) in an amount not exceeding 33⅓% of the fund’s total assets (including the amount borrowed) less liabilities (other than borrowings).
Lending A fund may not lend any security or make any other loan if, as a result, more than 33⅓% of the fund’s total assets would be lent to other parties, except, (i) through the purchase of debt securities in accordance with its investment objective, policies and limitations or (ii) by engaging in repurchase agreements with respect to portfolio securities.
Real Estate A fund may not purchase or sell real estate unless acquired as a result of ownership of securities or other instruments. This policy shall not prevent a fund from investing in securities or other instruments backed by real estate or securities of companies that deal in real estate or are engaged in the real estate business.
Concentration A fund may not concentrate its investments in securities of issuers in a particular industry (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities).
Underwriting A fund may not act as an underwriter of securities issued by others, except to the extent that the fund may be considered an underwriter within the meaning of the Securities Act of 1933 in the disposition of restricted securities.
Commodities A fund may not purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments provided that this limitation shall not prohibit the fund from purchasing or selling options and futures contracts or from investing in securities or other instruments backed by physical commodities.
Control A fund may not invest for purposes of exercising control over management.
 For purposes of the investment policy relating to senior securities, a fund may borrow from any bank provided that immediately after any such borrowing there is asset coverage of at least 300% for all borrowings of such fund. In the event that such asset coverage falls below 300%, the fund shall, within three days thereafter (not including Sundays and holidays) or such longer period as the SEC may prescribe by rules and regulations, reduce the amount of its borrowings to an extent that the asset coverage of such borrowings is at least 300%. In addition, when a fund enters into certain transactions involving potential leveraging, it will hold offsetting positions or segregate assets to cover such obligations at levels consistent with the guidance of the SEC and its staff.
For purposes of the investment policies relating to lending and borrowing, the funds have received an exemptive order from the SEC regarding an interfund lending program. Under the terms of the exemptive order, the funds may borrow money from or lend money to other American Century Investments-advised funds that permit such transactions. All such transactions will be subject to the limits for borrowing and lending set forth above. The funds will borrow money through the program only when the costs are equal to or lower than the costs of short-term bank loans. Interfund loans and borrowings normally extend only overnight but can have a maximum duration of seven days. The funds will lend through the program only when the returns are higher than those available from other short-term instruments (such as repurchase agreements). The funds may have to borrow from a bank at a higher interest rate if an interfund loan is called or not renewed. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.
28


For purposes of the investment policy relating to concentration, a fund shall not purchase any securities that would cause 25% or more of the value of the fund’s net assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that
(a)there is no limitation with respect to obligations issued or guaranteed by the U.S. government, any state, territory or possession of the United States, the District of Columbia or any of their authorities, agencies, instrumentalities or political subdivisions and repurchase agreements secured by such obligations (except that an Industrial Development Bond backed only by the assets and revenues of a non-governmental user will be deemed to be an investment in the industry represented by such user),
(b)wholly owned finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of their parents,
(c)utilities will be divided according to their services, for example, gas, gas transmission, electric and gas, electric, and telephone will each be considered a separate industry,
(d)personal credit and business credit businesses will be considered separate industries, and
(e)for Emerging Markets Debt, each industry will be subclassified by country for concentration purposes.
Nonfundamental Investment Policies
In addition, the funds are subject to the following investment policies that are not fundamental. These policies, along with the investment objectives of Emerging Markets Debt and International Bond, as set forth in each fund’s prospectus, may be changed by the Board of Trustees.
Subject Policy
Leveraging A fund may not purchase additional investment securities at any time during which outstanding borrowings exceed 5% of the total assets of the fund.
Liquidity A fund may not purchase any security or enter into a repurchase agreement if, as a result, more than 15% of its net assets would be invested in illiquid securities. Illiquid securities include repurchase agreements not entitling the holder to payment of principal and interest within seven days and in securities that are illiquid by virtue of legal or contractual restrictions on resale or the absence of a readily available market.
Short Sales A fund may not sell securities short, unless it owns or has the right to obtain securities equivalent in kind and amount to the securities sold short, and provided that transactions in futures contracts, options and other derivative instruments are not deemed to constitute selling securities short.
Margin A fund may not purchase securities on margin, except to obtain such short-term credits as are necessary for the clearance of transactions, and provided that margin payments and other deposits in connection with transactions involving futures, options (puts, calls, etc.), swaps, short sales, forward contracts, commitment agreements, and other similar investment techniques shall not be deemed to constitute purchasing securities on margin.
Futures and
Options
A fund may enter into futures contracts and write and buy put and call options relating to futures contracts. A fund may not, however, enter into leveraged futures transactions if it would be possible for the fund to lose more than the notional value of the investment.
Issuers with
Limited
Operating
Histories
A fund may invest a portion of its assets in the securities of issuers with limited operating histories. An issuer is considered to have a limited operating history if that issuer has a record of less than three years of continuous operation. Periods of capital formation, incubation, consolidations, and research and development may be considered in determining whether a particular issuer has a record of three years of continuous operation.
The Investment Company Act imposes certain additional restrictions upon the funds’ ability to acquire securities issued by insurance companies, broker-dealers, underwriters or investment advisors, and upon transactions with affiliated persons as defined by the Act. It also defines and forbids the creation of cross and circular ownership. Neither the SEC nor any other agency of the federal or state government participates in or supervises the management of the funds or their investment practices or policies.
Temporary Defensive Measures
For temporary defensive purposes, a fund may invest in securities that may not fit its investment objective or its stated market. During a temporary defensive period, a fund may direct its assets to the following investment vehicles:
interest-bearing bank accounts or Certificates of Deposit;
U.S. government securities and repurchase agreements collateralized by U.S. government securities; and
money market funds.
To the extent a fund assumes a defensive position, it may not achieve its investment objective.
Portfolio Turnover
The portfolio turnover rate of each fund for its most recent fiscal year is included in the Fund Summary section of that fund’s prospectus. The portfolio turnover rate for each fund’s last five fiscal years (or shorter period if the fund is less than five years old) is shown in the Financial Highlights tables in the prospectus.
29


The portfolio manager will sell securities without regard to the length of time the security has been held. Accordingly, the fund’s rate of portfolio turnover may be substantial.
The portfolio managers intend to purchase a particular security whenever they believe it will contribute to the stated objective of a particular fund. In order to achieve each fund’s investment objective, the portfolio managers may sell a given security, regardless of the length of time it has been held in the portfolio, and, regardless of the gain or loss realized on the sale. The managers may sell a portfolio security if they believe that the security is not fulfilling its purpose because, among other things, it did not live up to the managers’ expectations, because it may be replaced with another security holding greater promise, because it has reached its optimum potential, because of a change in the circumstances of a particular company or industry or in general economic conditions, or because of some combination of such reasons.
Because investment decisions are based on a particular security’s anticipated contribution to a fund’s objectives, the managers believe that the rate of portfolio turnover is irrelevant when they determine that a change is required to pursue the fund’s investment objective. As a result, a fund’s annual portfolio turnover rate cannot be anticipated and may be higher than other mutual funds with similar investment objectives. Portfolio turnover also may affect the character of capital gains realized and distributed by the fund, if any, since short-term capital gains are taxable as ordinary income.
Because the managers do not take portfolio turnover rate into account in making investment decisions, (1) the managers have no intention of maintaining any particular rate of portfolio turnover, whether high or low, and (2) the portfolio turnover rates in the past should not be considered as representative of the rates that will be attained in the future.
Variations in a fund’s portfolio turnover rate from year to year may be due to a fluctuating volume of shareholder purchase and redemption activity, varying market conditions, and/or changes in the manager’s investment outlook. The increase in turnover was largely seen in credit spread assets in the securitization markets as the fund moved between agency and non-agency exposures. In corporate markets, the significant increase in new issuance as companies increased liquidity reserves significantly increased the fund’s activity in the primary markets and spread volatility created more trading opportunities in secondary markets.
Disclosure of Portfolio Holdings
The advisor (ACIM) has adopted policies and procedures with respect to the disclosure of fund portfolio holdings and characteristics, which are described below.
Distribution to the Public
Month-end full portfolio holdings for each fund will generally be made available for distribution 15 days after the end of each calendar quarter for each of the preceding three months. This disclosure is in addition to the portfolio disclosure in annual and semiannual shareholder reports and the quarter-end portfolio disclosures on Form N-PORT. Such disclosures are filed with the Securities and Exchange Commission within 60 days of each fiscal quarter end and also posted on americancentury.com at approximately the same time the filings are made. The distribution of holdings after the above time periods is not limited.
On a monthly basis, top 10 holdings (on an absolute basis and relative to the appropriate benchmark) for each fund (except AC Alternatives Market Neutral Value Fund, which is limited to the top five pairs by type, as described below) will generally be made available for distribution 7 days after the end of each month, and will be posted on americancentury.com at approximately the same time.
Portfolio characteristics that are derived from portfolio holdings will be made available for distribution 7 days after the end of each month, or as soon thereafter as possible, which timeframe may vary by fund. Certain characteristics, as determined by the advisor, will be posted on americancentury.com monthly at approximately the time they are made available for distribution. Data derived from portfolio returns and any other characteristics not deemed confidential will be available for distribution at any time. The advisor may make determinations of confidentiality on a fund-by-fund basis, and may add or delete characteristics to or from those considered confidential at any time.
Any American Century Investments fund that sells securities short as an investment strategy will disclose full portfolio holdings in annual and semiannual shareholder reports and on Form N-PORT). These funds will make long and short holdings as of the end of a calendar quarter available for distribution 15 days after the end of each calendar quarter. These funds may also make limited disclosures as noted in the Single Event Requests section below. The distribution of holdings after the above time periods is not limited.
Examples of securities (both long and short) currently or previously held in a portfolio may be included in presentations or other marketing documents as soon as available. The inclusion of such examples is at the relevant portfolio’s team discretion.
So long as portfolio holdings are disclosed in accordance with the above parameters, the advisor makes no distinction among different categories of recipients, such as individual investors, institutional investors, intermediaries that distribute the funds’ shares, third-party service providers, rating and ranking organizations, and fund affiliates. Because this information is publicly available and widely disseminated, the advisor places no conditions or restrictions on, and does not monitor, its use. Nor does the advisor require special authorization for its disclosure.

30


Accelerated Disclosure
The advisor recognizes that certain parties, in addition to the advisor and its affiliates, may have legitimate needs for information about portfolio holdings and characteristics prior to the times prescribed above. Such accelerated disclosure is permitted under the circumstances described below.
Ongoing Arrangements
Certain parties, such as investment consultants who provide regular analysis of fund portfolios for their clients and intermediaries who pass through information to fund shareholders, may have legitimate needs for accelerated disclosure. These needs may include, for example, the preparation of reports for customers who invest in the funds, the creation of analyses of fund characteristics for intermediary or consultant clients, the reformatting of data for distribution to the intermediary’s or consultant’s clients, and the review of fund performance for ERISA fiduciary purposes.
In such cases, accelerated disclosure is permitted if the service provider enters an appropriate non-disclosure agreement with the fund’s distributor in which it agrees to treat the information confidentially until the public distribution date and represents that the information will be used only for the legitimate services provided to its clients (i.e., not for trading). Non-disclosure agreements require the approval of an attorney in the advisor’s legal department. The advisor’s compliance department receives quarterly reports detailing which clients received accelerated disclosure, what they received, when they received it and the purposes of such disclosure. Compliance personnel are required to confirm that an appropriate non-disclosure agreement has been obtained from each recipient identified in the reports.

Once a party has executed a non-disclosure agreement, it may receive any or all of the following data for funds in which its clients have investments or are actively considering investment:
(1) Full holdings (both long and short) quarterly as soon as reasonably available;
(2) Full holdings (long only) monthly as soon as reasonably available;
(3) Top 10 holdings (top 5 pairs for each type for AC Alternatives Market Neutral Value Fund) monthly as soon as reasonably available; and
(4) Portfolio attributes (such as sector or country weights), characteristics and performance attribution monthly as soon as reasonably available.
The types, frequency and timing of disclosure to such parties vary.
Single Event Requests
In certain circumstances, the advisor may provide fund holding information on an accelerated basis outside of an ongoing arrangement with manager-level or higher authorization. For example, from time to time the advisor may receive requests for proposals (RFPs) from consultants or potential clients that request information about a fund’s holdings on an accelerated basis. As long as such requests are on a one-time basis, and do not result in continued receipt of data, such information may be provided in the RFP. In these circumstances, top 15 long and short holdings may be disclosed 7 days after the end of each month. Such disclosure may be presented in paired trades, such as by showing a long holding in one sector or security and a corresponding short holding in another sector or security together to show a long/short strategy. Such information will be provided with a confidentiality legend and only in cases where the advisor has reason to believe that the data will be used only for legitimate purposes and not for trading.
33


Service Providers
Various service providers to the fund and the fund’s advisor must have access to some or all of the fund’s portfolio holdings information on an accelerated basis from time to time in the ordinary course of providing services to the funds. These service providers include the fund’s custodian (daily, with no lag), auditors (as needed) and brokers involved in the execution of fund trades (as needed). Additional information about these service providers and their relationships with the fund and the advisor are provided elsewhere in this statement of additional information. In addition, the fund’s investment advisor may use analytical systems provided by third party data aggregators who have access to the fund’s portfolio holdings daily, with no lag. These data aggregators enter into separate non-disclosure agreements after authorization by an appropriate officer of the advisor. The agreements with service providers and data aggregators generally require that they treat the funds’ portfolio holdings information confidentially until the public distribution date and represent that the information will be used only for the legitimate services it provides (i.e., not for trading).
Additional Safeguards
The advisor’s policies and procedures include a number of safeguards designed to control disclosure of portfolio holdings and characteristics so that such disclosure is consistent with the best interests of fund shareholders, including procedures to address conflicts between the interests of shareholders and those of the advisor and its affiliates. First, the frequency with which this information is disclosed to the public, and the length of time between the date of the information and the date on which the information is disclosed, are selected to minimize the possibility of a third party improperly benefiting from fund investment decisions to the detriment of fund shareholders. In the event that a request for portfolio holdings or characteristics creates a potential conflict of interest that is not addressed by the safeguards and procedures described above, the advisor’s procedures require that such requests may only be granted with the approval of the advisor’s legal department and the relevant chief investment officers. In addition, distribution of portfolio holdings information, including compliance with the advisor’s policies and the resolution of any potential conflicts that may arise, is monitored quarterly by the advisor’s compliance department. Finally, the funds’ Board of Trustees exercises oversight of disclosure of the funds’ portfolio securities. The board has received and reviewed a summary of the advisor’s policy and is informed on a quarterly basis of any changes to or violations of such policy detected during the prior quarter. 
Neither the advisor nor the funds receive any compensation from any party for the distribution of portfolio holdings information.
The advisor reserves the right to change its policies and procedures with respect to the distribution of portfolio holdings information at any time. There is no guarantee that these policies and procedures will protect the funds from the potential misuse of holdings information by individuals or firms in possession of such information.
Management
Board of Trustees
The individuals listed below serve as trustees of the funds. Each trustee will continue to serve in this capacity until death, retirement, resignation or removal from office. The board has adopted a mandatory retirement age for trustees who are not “interested persons,” as that term is defined in the Investment Company Act (independent trustees). Independent trustees shall retire on December 31 of the year in which they reach their 76th birthday.
Jonathan S. Thomas is an “interested person” because he currently serves as President and Chief Executive Officer of American Century Companies, Inc. (ACC), the parent company of American Century Investment Management, Inc. (ACIM or the advisor). The other trustees (more than three-fourths of the total number) are independent. They are not employees, directors or officers of, and have no financial interest in, ACC or any of its wholly owned, direct or indirect, subsidiaries, including ACIM, American Century Investment Services, Inc. (ACIS) and American Century Services, LLC (ACS), and they do not have any other affiliations, positions or relationships that would cause them to be considered “interested persons” under the Investment Company Act. The trustees serve in this capacity for eight (in the case of Jonathan S. Thomas, 16; and Jeremy I. Bulow, 9) registered investment companies in the American Century Investments family of funds.
The following table presents additional information about the trustees. The mailing address for each trustee other than Jonathan S. Thomas is 3945 Freedom Circle, Suite #800, Santa Clara, California 95054. The mailing address for Jonathan S. Thomas is 4500 Main Street, Kansas City, Missouri 64111.

Qualifications of Trustees
Generally, no one factor was decisive in the selection of the trustees to the board. Qualifications considered by the board to be important to the selection and retention of trustees include the following: (i) the individual’s business and professional experience and accomplishments; (ii) the individual’s educational background and accomplishments; (iii) the individual’s experience and expertise performing senior policy-making functions in business, government, education, accounting, law and/or administration; (iv) how the individual’s expertise and experience would contribute to the mix of relevant skills and experience on the board; (v) the individual’s ability to work effectively with the other members of the board; and (vi) the individual’s ability and willingness to make the time commitment necessary to serve as an effective trustee. In addition, the individuals’ ability to review and critically evaluate information, their ability to evaluate fund service providers, their ability to exercise good business judgment on behalf of fund shareholders, their prior service on the board, and their familiarity with the funds are considered important assets.
While the board has not adopted a specific policy on diversity, it takes overall diversity into account when considering and evaluating nominees for trustee. The board generally considers the manner in which each trustee’s professional experience, background, skills, and other individual attributes will contribute to the effectiveness of the board. Additional information about each trustee’s individual educational and professional experience (supplementing the information provided in the table above) follows.

Responsibilities of the Board
The board is responsible for overseeing the advisor’s management and operations of the fund pursuant to the management agreement. Trustees also have significant responsibilities under the federal securities laws. Among other things, they:
oversee the performance of the funds;
oversee the quality of the advisory and shareholder services provided by the advisor;
review annually the fees paid to the advisor for its services;
monitor potential conflicts of interest between the funds and their affiliates, including the advisor;
oversee custody of assets and the valuation of securities; and
oversee the funds’ compliance program.
In performing their duties, board members receive detailed information about the funds and the advisor regularly throughout the year, and they meet in person at least quarterly with management of the advisor to review reports about fund operations. Certain Board committee members also hold periodic telephone conferences with management between quarterly board meetings. The trustees’ role is to provide oversight and not to provide day-to-day management.
The board has all powers necessary or convenient to carry out its responsibilities. Consequently, the board may adopt bylaws providing for the regulation and management of the affairs of the funds and may amend and repeal them to the extent that such bylaws do not reserve that right to the funds’ shareholders. They may increase or reduce the number of board members and may, subject to the Investment Company Act, fill board vacancies. Board members also may elect and remove such officers and appoint and terminate such agents as they consider appropriate. They may establish and terminate committees consisting of two or more trustees who may exercise the powers and authority of the board as determined by the trustees. They may, in general, delegate such authority as they consider desirable to any officer of the funds, to any board committee and to any agent or employee of the funds or to any custodian, transfer agent, investor servicing agent, principal underwriter or other service provider for a fund.
To communicate with the board, or a member of the board, a shareholder should send a written communication addressed to the board or member of the board to the attention of the Corporate Secretary at the following address: P.O. Box 418210, Kansas City, Missouri 64141-9210. Shareholders who prefer to communicate by email may send their comments to [email protected]. All shareholder communications received will be forwarded to the board or to the independent board chair.
Board Leadership Structure and Standing Board Committees
Tanya S. Beder currently serves as the independent board chair and has served in such capacity since 2022. Of the board’s members, Jonathan S. Thomas is the only member who is an “interested person” as that term is defined in the Investment Company Act. The remaining members are independent trustees. The independent trustees meet separately to consider a variety of matters that are scheduled to come before the board and meet periodically with the fund’s Chief Compliance Officer and fund auditors. They are advised by independent legal counsel. No independent trustee may serve as an officer or employee of a fund. The board has also established several committees, as described below. Each committee is comprised solely of independent trustees. The board believes that the current leadership structure, with independent trustees filling all but one position on the board, with an independent trustee serving as board chair and with the board committees comprised only of independent trustees, is appropriate and allows for independent oversight of the fund.
The board has an Audit and Compliance Committee that approves the funds’ engagement of the independent registered public accounting firm and recommends approval of such engagement to the independent trustees. The committee also oversees the activities of the accounting firm, receives regular reports regarding fund accounting, oversees securities valuation (approving the funds’ or the

trust’s valuation policy and receiving reports regarding instances of fair valuation thereunder), and receives regular reports from the advisor’s internal audit department. The committee also reviews the results of the funds’ compliance testing program, meets regularly with the fund’s Chief Compliance Officer, and monitors implementation of the funds’ Code of Ethics. The committee currently consists of Peter F. Pervere (chair), Tanya S. Beder, Jennifer Cabalquinto and Anne Casscells. The committee met four times during the funds’ fiscal year ended October 31, 2022.
The board also has a Portfolio Committee that meets quarterly to review the investment activities and strategies used to manage the funds’ assets and monitor investment performance. The committee regularly receives reports from the advisor’s Chief Investment Officer, portfolio managers, credit analysts and other investment personnel concerning the funds’ investments. The committee also receives information regarding fund trading activities and monitors derivative usage. It currently consists of Anne Casscells (chair), Tanya S. Beder, Jeremy I. Bulow, Jonathan D. Levin and John B. Shoven. The committee met four times during the funds’ fiscal year ended October 31, 2022.
The Client Experience Oversight Committee monitors the quality of services that the funds offer both to direct customers and to intermediaries who offer fund shares to their customers. All channels of communication (written, telephone, web and mobile) are reviewed. The level of performance is compared to peer competitors. The committee also monitors payments to intermediaries and trading in fund shares that could harm the interests of other shareholders and reviews future strategic initiatives of the advisor and their potential effects on fund shareholders. The committee currently consists of John B. Shoven (chair), Jeremy I. Bulow, Jonathan D. Levin and Peter F. Pervere. The committee met four times during the funds’ fiscal year ended October 31, 2022.
The Technology and Risk Committee coordinates the board’s oversight of the funds’ risk management processes and monitors the systems, practices and procedures the advisor uses to manage the funds’ risks. In addition, the committee oversees enterprise technology risk management and the advisor’s processes for oversight of vendors that provide critical services or technologies to the funds or on which the advisor relies in providing services to the funds. It also makes recommendations to the board regarding the allocation of risk oversight activities among the board’s committees. The committee currently consists of Jennifer Cabalquinto (chair), Tanya S. Beder, Anne Casscells and Peter F. Pevere. The committee met four times during the funds’ fiscal year ended October 31, 2022.
The board has a Corporate Governance Committee that is responsible for reviewing board procedures and committee structures. The committee also considers and recommends individuals for nomination as trustees. The names of potential trustee candidates may be drawn from a number of sources, including recommendations from members of the board, the advisor (in the case of interested trustees only), shareholders and third party search firms. The committee seeks to identify and recruit the best available candidates and will evaluate qualified shareholder nominees on the same basis as those identified through other sources. Although not written, the fund has a policy of considering all candidates recommended in writing by shareholders. Shareholders may submit trustee nominations in writing to the Corporate Secretary, P.O. Box 418210, Kansas City, Missouri 64141-9210, or by email to [email protected]. The nomination should include the following information:
Shareholder’s name, the fund name, number of fund shares owned and length of period held;
Name, age and address of the candidate;
A detailed resume describing, among other things, the candidate’s educational background, occupation, employment history, financial knowledge and expertise and material outside commitments (e.g., memberships on other boards and committees, charitable foundations, etc.);
Any other information relating to the candidate that is required to be disclosed in solicitations of proxies for election of trustees in an election contest pursuant to Regulation 14A under the Securities Exchange Act of 1934;
A supporting statement that (i) describes the candidate’s reasons for seeking election to the board and(ii) documents his/her qualifications to serve as a trustee; and
A signed statement from the candidate confirming his/her willingness to serve on the board.
The Corporate Governance Committee also may consider, and make recommendations to the board regarding, other matters relating to the corporate governance of the funds. It currently consists of Jonathan D. Levin (chair), Tanya S. Beder, Jeremy I. Bulow and John B. Shoven. The committee met four times during the funds’ fiscal year ended October 31, 2022.
Risk Oversight by the Board
As previously disclosed, the board oversees the advisor’s management of the funds and meets at least quarterly with management of the advisor to review reports and receive information regarding fund operations. Risk oversight relating to the funds is one component of the board’s oversight and is undertaken in connection with the duties of the board. As described in the previous section, the board’s committees, including the Technology and Risk Committee, assist the board in overseeing various types of risks relating to the funds. The board receives regular reports from each committee regarding the committee’s areas of oversight responsibility. In addition, the board receives information regarding, and has discussions with senior management of the advisor about, the advisor’s enterprise risk management systems and strategies. There can be no assurance that all elements of risk, or even all elements of material risk, will be disclosed to or identified by the board, or that the advisor’s risk management systems and strategies, and the board’s oversight thereof, will mitigate all elements of risk, or even all elements of material risk, to the funds.

None of the interested trustees or officers of the funds receive compensation from the funds. For the fiscal year ended October 31, 2022, each independent trustee received the following compensation for his or her service to the funds and the American Century family of funds.

1    Includes compensation paid to the trustees for fiscal year ended October 31, 2022, and also includes amounts deferred at the election of the trustees under the American Century Mutual Funds’ Independent Directors’ Deferred Compensation Plan.
2    Includes compensation paid to each trustee for his or her service as director/trustee for eight (in the case of Mr. Bulow and Mr. Gilson, nine) investment companies in the American Century Investments family of funds. The total amount of deferred compensation included in the table is as follows: Mr. Bulow, $86,459; Ms. Casscells, $305,000; and Mr. Pervere, $31,333.
3    Mr. Gilson and Mr. Grauer retired from the board on December 31, 2021.
None of the funds currently provides any pension or retirement benefits to the trustees except pursuant to the American Century Mutual Funds’ Independent Directors’ Deferred Compensation Plan adopted by the trust. Under the plan, the independent trustees may defer receipt of all or any part of the fees to be paid to them for serving as trustees of the funds. All deferred fees are credited to accounts established in the names of the trustees. The amounts credited to each account then increase or decrease, as the case may be, in accordance with the performance of one or more American Century funds selected by the trustees. The account balance continues to fluctuate in accordance with the performance of the selected fund or funds until final payment of all amounts credited to the account. Trustees are allowed to change their designation of funds from time to time.
Generally, deferred fees are not payable to a trustee until the distribution date elected by the trustee in accordance with the terms of the plan. Such distribution date may be a date on or after the trustee’s retirement date, but may be an earlier date if the trustee agrees not to make any additional deferrals after such distribution date. Distributions may commence prior to the elected payment date for certain reasons specified in the plan, such as unforeseeable emergencies, death or disability. Trustees may receive deferred fee account balances either in a lump sum payment or in substantially equal installment payments to be made over a period not to exceed 10 years. Upon the death of a trustee, all remaining deferred fee account balances are paid to the trustee’s beneficiary or, if none, to the trustee’s estate.
The plan is an unfunded plan and, accordingly, the funds have no obligation to segregate assets to secure or fund the deferred fees. To date, the funds have met all payment obligations under the plan. The rights of trustees to receive their deferred fee account balances are the same as the rights of a general unsecured creditor of the fund. The plan may be terminated at any time by the administrative committee of the plan. If terminated, all deferred fee account balances will be paid in a lump sum.

Code of Ethics
The funds, their investment advisor and principal underwriter have adopted codes of ethics under Rule 17j-1 of the Investment Company Act. They permit personnel subject to the codes to invest in securities, including securities that may be purchased or held by the funds, provided that they first obtain approval from the compliance department before making such investments.
Proxy Voting Policies
The funds’ Board of Trustees has adopted a general statement of proxy voting principles that governs the exercise of voting and consent rights associated with the securities purchased and/or held by the funds. The funds have delegated to the advisor the responsibility for exercising such rights, subject to the board’s oversight. The advisor has adopted proxy voting policies that describe in detail how the advisor intends to exercise its delegated proxy voting authority in a manner consistent with the board’s principles.
Copies of the advisor’s proxy voting policies are attached hereto as Appendix E. Copies of the board’s proxy voting principles, as well as information regarding how the advisor voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 are available at americancentury.com/proxy. The advisor’s proxy voting record also is available on the SEC’s website at sec.gov. 
The Funds’ Principal Shareholders
A list of the funds’ principal shareholders appears in Appendix A.
Service Providers 
The funds have no employees. To conduct the funds’ day-to-day activities, the trust has hired a number of service providers. Each service provider has a specific function to fill on behalf of the funds that is described below. 
ACIM, ACS and ACIS are wholly owned, directly or indirectly, by ACC. The Stowers Institute for Medical Research (SIMR) controls ACC by virtue of its beneficial ownership of more than 25% of the voting securities of ACC. SIMR is part of a not-for-profit biomedical research organization dedicated to finding the keys to the causes, treatments and prevention of disease. 
Investment Advisor 
American Century Investment Management, Inc. (ACIM) serves as the investment advisor for each of the funds. A description of the responsibilities of the advisor (ACIM) appears in each prospectus under the heading Management. 
Each class of each fund is subject to a contractual unified management fee based on a percentage of the daily net assets of such class. For more information about the unified management fee, see The Investment Advisor under the heading Management in each fund’s prospectus. 
Emerging Markets Debt Fund
The unified management fee for each of the Investor Class, A Class, C Class and R Class is 0.96%. The unified management fee for the I Class is 0.86%. The unified management fee for the Y Class and R5 Class is 0.76%. The unified management fee for the R6 Class and G Class is 0.71%. The amount of the fee is calculated daily and paid monthly in arrears. 
Global Bond Fund
The unified management fee for each of the Investor Class, A Class, C Class and R Class is 0.83%. The unified management fee for the I Class is 0.73%. The unified management fee for the Y Class and R5 Class is 0.63%. The unified management fee for the R6 Class and G Class is 0.58%. The amount of the fee is calculated daily and paid monthly in arrears. 
International Bond Fund
The annual rate at which the unified management fee is assessed is determined daily in a multi-step process. First, the fund is categorized according to the broad asset class in which it invests (e.g., money market, bond or equity), and the assets of all funds for which ACIM serves as the investment advisor and for which American Century Investment Services, Inc. (ACIS) serves as the distributor are totaled for each category (“Fund Category Assets”). Second, the assets are totaled for certain other accounts managed by the advisor (“Other Account Category Assets”). To be included, these accounts must have the same management team and
40


investment objective as a fund in the same category with the same Board of Trustees as the trust. Together, the Fund Category Assets and the Other Account Category Assets comprise the “Investment Category Assets.” The Investment Category Fee Rate is then calculated by applying the fund’s Investment Category Fee Schedule to the Investment Category Assets and dividing the result by the Investment Category Assets.
Finally, a separate Complex Fee Schedule is applied to the assets of all funds for which ACIM serves as the investment advisor and for which ACIS serves as the distributor (the “Complex Assets”), and the Complex Fee Rate is calculated based on the resulting total. The Investment Category Fee Rate and the Complex Fee Rate are then added to determine the Management Fee Rate payable by a class of the fund to the advisor. 
For purposes of determining the assets that comprise the Fund Category Assets, Other Account Category Assets and Complex Assets, the assets of registered investment companies managed by the advisor that invest exclusively in the shares of other registered investment companies shall not be included. 
The schedules by which the unified management fee for International Bond is determined are shown below. 
Investment Category Fee Schedule for International Bond
Category Assets Fee Rate
First $1 billion 0.6100%
Next $1 billion 0.5580%
Next $3 billion 0.5280%
Next $5 billion 0.5080%

Thereafter 0.2500% 0.1500% 0.0500% 0.0000%
All Funds in American Century International Bond Funds
On each calendar day, each class of each fund accrues a management fee that is equal to the class’s Management Fee Rate times the net assets of the class divided by 365 (366 in leap years). On the first business day of each month, the funds pay a management fee to the advisor for the previous month. The fee for the previous month is the sum of the calculated daily fees for each class of a fund during the previous month. 
The management agreement between the trust and the advisor shall continue in effect for a period of two years from its effective date (unless sooner terminated in accordance with its terms) and shall continue in effect from year to year thereafter for each fund so long as such continuance is approved at least annually by:
(1)either the funds’ Board of Trustees, or a majority of the outstanding voting securities of such fund (as defined in the Investment Company Act); and
(2)the vote of a majority of the trustees of the funds who are not parties to the agreement, or interested persons of the advisor, cast in person at a meeting called for the purpose of voting on such approval.
41


The management agreement states that the funds’ Board of Trustees or a majority of the outstanding voting securities of each class of such fund may terminate the management agreement at any time without payment of any penalty on 60 days’ written notice to the advisor. The management agreement shall be automatically terminated if it is assigned. 
The management agreement states that the advisor shall not be liable to the funds or its shareholders for anything other than willful misfeasance, bad faith, gross negligence or reckless disregard of its obligations and duties. 
The management agreement also provides that the advisor and its officers, trustees or directors and employees may engage in other business, render services to others, and devote time and attention to any other business whether of a similar or dissimilar nature. 
Certain investments may be appropriate for the funds and also for other clients advised by the advisor. Investment decisions for the funds and other clients are made with a view to achieving their respective investment objectives after consideration of such factors as their current holdings, availability of cash for investment and the size of their investment generally. A particular security may be bought or sold for only one client or fund, or in different amounts and at different times for more than one but less than all clients or funds. A particular security may be bought for one client or fund on the same day it is sold for another client or fund, and a client or fund may hold a short position in a particular security at the same time another client or fund holds a long position. In addition, purchases or sales of the same security may be made for two or more clients or funds on the same date. The advisor has adopted procedures designed to ensure such transactions will be allocated among clients and funds in a manner believed by the advisor to be equitable to each. In some cases this procedure could have an adverse effect on the price or amount of the securities purchased or sold by the fund. 
The advisor may aggregate purchase and sale orders of the funds with purchase and sale orders of its other clients when the advisor believes that such aggregation provides the best execution for the funds. The Board of Trustees has approved the policy of the advisor with respect to the aggregation of portfolio transactions. Fixed-income securities transactions are not executed through a centralized trading desk. Instead, portfolio teams are responsible for executing trades with broker-dealers in a predominantly dealer marketplace. Trade allocation decisions are made by the portfolio managers at the time of trade execution and orders entered on the fixed-income order management system. The advisor will not aggregate portfolio transactions of the funds unless it believes such aggregation is consistent with its duty to seek best execution on behalf of the funds and the terms of the management agreement. The advisor receives no additional compensation or remuneration as a result of such aggregation. 
Unified management fees incurred by the funds for the fiscal years ended October 31, 2022, October 31, 2021 and October 31, 2020, are indicated in the following table.

Potential Conflicts of Interest
Certain conflicts of interest may arise in connection with the management of multiple portfolios. Potential conflicts include, for example, conflicts among investment strategies, such as one portfolio buying or selling a security while another portfolio has a differing, potentially opposite position in such security. This may include one portfolio taking a short position in the security of an issuer that is held long in another portfolio (or vice versa). Other potential conflicts may arise with respect to the allocation of investment opportunities, which are discussed in more detail below. American Century Investments has adopted policies and procedures that are designed to minimize the effects of these conflicts. 
Responsibility for managing American Century Investments client portfolios is organized according to investment discipline. Investment disciplines include, for example, disciplined equity, global growth equity, global value equity, global fixed-income, multi-asset strategies, exchange traded funds, and Avantis Investors funds. Within each discipline are one or more portfolio teams responsible for managing specific client portfolios. Generally, client portfolios with similar strategies are managed by the same team using the same objective, approach, and philosophy. Accordingly, portfolio holdings, position sizes, and industry and sector exposures tend to be similar across similar portfolios, which minimizes the potential for conflicts of interest. In addition, American Century Investments maintains an ethical wall that restricts real time access to information regarding any portfolio’s transaction activities and positions to team members that have responsibility for a given portfolio or are within the same equity investment discipline. The ethical wall is intended to aid in preventing the misuse of portfolio holdings information and trading activity in other disciplines. 
For each investment strategy, one portfolio is generally designated as the “policy portfolio.” Other portfolios with similar investment objectives, guidelines and restrictions, if any, are referred to as “tracking portfolios.” When managing policy and tracking portfolios, a portfolio team typically purchases and sells securities across all portfolios that the team manages. American Century Investments’ trading systems include various order entry programs that assist in the management of multiple portfolios, such as the ability to purchase or sell the same relative amount of one security across several funds. In some cases a tracking portfolio may have additional restrictions or limitations that cause it to be managed separately from the policy portfolio. Portfolio managers make purchase and sale decisions for such portfolios alongside the policy portfolio to the extent the overlap is appropriate, and separately, if the overlap is not. 
American Century Investments may aggregate orders to purchase or sell the same security for multiple portfolios when it believes such aggregation is consistent with its duty to seek best execution on behalf of its clients. Orders of certain client portfolios may, by investment restriction or otherwise, be determined not available for aggregation. American Century Investments has adopted policies
43


and procedures to minimize the risk that a client portfolio could be systematically advantaged or disadvantaged in connection with the aggregation of orders. To the extent equity trades are aggregated, shares purchased or sold are generally allocated to the participating portfolios pro rata based on order size. Because initial public offerings (IPOs) are usually available in limited supply and in amounts too small to permit across-the-board pro rata allocations, American Century Investments has adopted special procedures designed to promote a fair and equitable allocation of IPO securities among clients over time. A centralized trading desk executes all fixed income securities transactions for Avantis ETFs and mutual funds. For all other funds in the American Century complex, portfolio teams are responsible for executing fixed income trades with broker/dealers in a predominantly dealer marketplace. Trade allocation decisions are made by the portfolio manager at the time of trade execution and orders entered on the fixed-income order management system. 
Finally, investment of American Century Investments’ corporate assets in proprietary accounts may raise additional conflicts of interest. To mitigate these potential conflicts of interest, American Century Investments has adopted policies and procedures intended to provide that trading in proprietary accounts is performed in a manner that does not give improper advantage to American Century Investments to the detriment of client portfolios. 
Compensation
American Century Investments portfolio manager compensation is structured to align the interests of portfolio managers with those of the shareholders whose assets they manage. As of October 31, 2022, it included the components described below, each of which is determined with reference to a number of factors such as overall performance, market competition, and internal equity.
Base Salary 
Portfolio managers receive base pay in the form of a fixed annual salary. 
Bonus 
A significant portion of portfolio manager compensation takes the form of an annual incentive bonus, which is determined by a combination of factors. One factor is investment performance. The mutual funds’ investment performance is generally measured by a combination of one-, three- and five-year pre-tax performance relative to various benchmarks and/or internally-customized peer groups, such as those indicated below. The performance comparison periods may be adjusted based on a fund’s inception date or a portfolio manager’s tenure on the fund.
Fund Benchmarks Peer Group
Emerging Markets Debt 50% JP Morgan GBI-EMBI Global Diversified Index/50% JP Morgan GBI-EM Global Diversified Index EAA Fund Global Emerging Markets Bond
US Fund Emerging Markets Bond
Global Bond Bloomberg Global Aggregate Bond Index (USD, hedged) Morningstar Global Bond-USD Hedged
International Bond
Bloomberg Global Aggregate Bond ex-USD (Unhedged)1
Morningstar Global Bond
1    Prior to January 1, 2015, this benchmark was the Barclays Global Treasury ex-US Bond Index; 25% weight in Japan and 5% maximum weights in Austria, Ireland, Finland and Portugal; minimum AA quality; FX-adjusted (investable index).
Portfolio managers may have responsibility for multiple American Century Investments mutual funds. In such cases, the performance of each is assigned a percentage weight appropriate for the portfolio manager’s relative levels of responsibility. Portfolio managers also may have responsibility for other types of managed portfolios or ETFs. If the performance of a managed account or ETF is considered for purposes of compensation, it is generally measured via the same criteria as an American Century Investments mutual fund (i.e., relative to the performance of a benchmark and/or peer group). 
A second factor in the bonus calculation relates to the performance of a number of American Century Investments mutual funds managed according to one of the following investment disciplines: global growth equity, global value equity, disciplined equity, global fixed-income and multi-asset strategies. The performance of American Century ETFs may also be included for certain investment disciplines. Performance is measured for each product individually as described above and then combined to create an overall composite for the product group. These composites may measure one-year performance (equal weighted) or a combination of one-, three- and five-year performance (equal or asset weighted) depending on the portfolio manager’s responsibilities and products managed and the composite for certain portfolio managers may include multiple disciplines. This feature is designed to encourage effective teamwork among portfolio management teams in achieving long-term investment success for similarly styled portfolios.
A portion of portfolio managers’ bonuses may be discretionary and may be tied to factors such as profitability or individual performance goals, such as research projects and/or the development of new products.

Restricted Stock Plan 
Portfolio managers are eligible for grants of restricted stock of ACC. These grants are discretionary, and eligibility and availability can vary from year to year. The size of an individual’s grant is determined by individual and product performance as well as other product-specific considerations such as profitability. Grants can appreciate/depreciate in value based on the performance of the ACC stock during the restriction period (generally three to four years).
Deferred Compensation Plans 
Portfolio managers are eligible for grants of deferred compensation. These grants are used in very limited situations, primarily for retention purposes. Grants are fixed and can appreciate/depreciate in value based on the performance of the American Century Investments mutual funds in which the portfolio manager chooses to invest them.

Brokerage Allocation
The advisor places orders for equity portfolio transactions with broker-dealers, who receive commissions for their services. Generally, commissions relating to securities traded on foreign exchanges will be higher than commissions relating to securities traded on U.S. exchanges. The advisor purchases and sells fixed-income securities through principal transactions, meaning the advisor normally purchases securities on a net basis directly from the issuer or a primary market-maker acting as principal for the securities. The funds generally do not pay a stated brokerage commission on these transactions, although the purchase price for debt securities usually includes an undisclosed compensation. Purchases of securities from underwriters typically include a commission or concession paid by the issuer to the underwriter, and purchases from dealers serving as market-makers typically include a dealer’s mark-up (i.e., a spread between the bid and asked prices).
Under the management agreement between the funds and the advisor, the advisor has the responsibility of selecting brokers and dealers to execute portfolio transactions. The funds’ policy is to secure the most favorable prices and execution of orders on its portfolio transactions. The advisor selects broker-dealers on their perceived ability to obtain “best execution” in effecting transactions in its clients’ portfolios. In selecting broker-dealers to effect portfolio transactions relating to equity securities, the advisor considers the full range and quality of a broker-dealer’s research and brokerage services, including, but not limited to, the following:
applicable commission rates and other transaction costs charged by the broker-dealer
value of research provided to the advisor by the broker-dealer (including economic forecasts, fundamental and technical advice on individual securities, market analysis, and advice, either directly or through publications or writings, as to the value of securities, availability of securities or of purchasers/sellers of securities)
timeliness of the broker-dealer’s trade executions
efficiency and accuracy of the broker-dealer’s clearance and settlement processes
broker-dealer’s ability to provide data on securities executions
financial condition of the broker-dealer
the quality of the overall brokerage and customer service provided by the broker-dealer
In transactions to buy and sell fixed-income securities, the selection of the broker-dealer is determined by the availability of the desired security and its offering price, as well as the broker-dealer’s general execution and operational and financial capabilities in the type of transaction involved. The advisor will seek to obtain prompt execution of orders at the most favorable prices or yields. The advisor does not consider the receipt of products or services other than brokerage or research services in selecting broker-dealers. 
On an ongoing basis, the advisor seeks to determine what levels of commission rates are reasonable in the marketplace. In evaluating the reasonableness of commission rates, the advisor considers: 
rates quoted by broker-dealers
the size of a particular transaction, in terms of the number of shares, dollar amount, and number of clients involved
the ability of a broker-dealer to execute large trades while minimizing market impact the complexity of a particular transaction
the nature and character of the markets on which a particular trade takes place
the level and type of business done with a particular firm over a period of time
the ability of a broker-dealer to provide anonymity while executing trades
historical commission rates
rates that other institutional investors are paying, based on publicly available information
The brokerage commissions paid by the funds may exceed those that another broker-dealer might have charged for effecting the same transactions, because of the value of the brokerage and research services provided by the broker-dealer. Research services furnished by broker-dealers through whom the funds effect securities transactions may be used by the advisor in servicing all of its accounts, and not all such services may be used by the advisor in managing the portfolios of the funds. 
Pursuant to its internal allocation procedures, the advisor regularly evaluates the brokerage and research services provided by each broker-dealer that it uses. On a periodic basis, members of the advisor’s portfolio management team assess the quality and value of research and brokerage services provided by each broker-dealer that provides execution services and research to the advisor for its clients’ accounts. The results of the periodic assessments are used to add or remove brokers from the approved brokers list, if needed, and to set research budgets for the following period. Execution-only brokers are used where deemed appropriate.

Information About Fund Shares 
The Declaration of Trust permits the Board of Trustees to issue an unlimited number of full and fractional shares of beneficial interest without par value, which may be issued in series (or funds). Each of the funds named on the front of this statement of additional information is a series of shares issued by the trust. In addition, each series (or fund) may be divided into separate classes. See Multiple Class Structure which follows. Additional funds and classes may be added without a shareholder vote. 
Each fund votes separately on matters affecting that fund exclusively. Voting rights are not cumulative, so that investors holding more than 50% of the trust’s (all funds’) outstanding shares may be able to elect a Board of Trustees. The trust undertakes dollar-based voting, meaning that the number of votes a shareholder is entitled to is based upon the dollar amount of the shareholder’s investment. The election of trustees is determined by the votes received from all the trust’s shareholders without regard to whether a majority of shares of any one fund voted in favor of a particular nominee or all nominees as a group. 
Each shareholder has rights to dividends and distributions declared by the fund he or she owns and to the net assets of such fund upon its liquidation or dissolution proportionate to his or her share ownership interest in the fund. Shares of each fund have equal voting rights, although each fund votes separately on matters affecting that fund exclusively.
The trust shall continue unless terminated by (1) approval of at least two-thirds of the shares of each fund entitled to vote or (2) the trustees by written notice to shareholders of each fund. Any fund may be terminated by (1) approval of at least two-thirds of the shares of that fund or (2) the trustees by written notice to shareholders of that fund. 
48


Upon termination of the trust or a fund, as the case may be, the trust shall pay or otherwise provide for all charges, taxes, expenses and liabilities belonging to the trust or the fund. Thereafter, the trust shall reduce the remaining assets belonging to each fund (or the particular fund) to cash, shares of other securities or any combination thereof, and distribute the proceeds belonging to each fund (or the particular fund) to the shareholders of that fund ratably according to the number of shares of that fund held by each shareholder on the termination date. 
Shareholders of a Massachusetts business trust could, under certain circumstances, be held personally liable for its obligations. However, the Declaration of Trust contains an express disclaimer of shareholder liability for acts or obligations of the trust. The Declaration of Trust also provides for indemnification and reimbursement of expenses of any shareholder held personally liable for obligations of the trust. The Declaration of Trust provides that the trust will, upon request, assume the defense of any claim made against any shareholder for any act or obligation of the trust and satisfy any judgment thereon. The Declaration of Trust further provides that the trust may maintain appropriate insurance (for example, fidelity, bonding and errors and omissions insurance) for the protection of the trust, its shareholders, trustees, officers, employees and agents to cover possible tort and other liabilities. Thus, the risk of a shareholder incurring financial loss as a result of shareholder liability is limited to circumstances in which both inadequate insurance exists and the trust is unable to meet its obligations. 
The assets belonging to each series or class of shares are held separately by the custodian and the shares of each series or class represent a beneficial interest in the principal, earnings and profit (or losses) of investments and other assets held for each fund or class. Your rights as a shareholder are the same for all series of securities unless otherwise stated. Within their respective series or class, all shares have equal redemption rights. Each share, when issued, is fully paid and non-assessable. 
Multiple Class Structure
The Board of Trustees has adopted a multiple class plan pursuant to Rule 18f-3 under the Investment Company Act. The plan is described in the prospectus of any fund that offers more than one class. Pursuant to such plan, the funds may issue the following classes of shares: Investor Class, I Class, Y Class, A Class, C Class, R Class, R5 Class, R6 Class and G Class. Not all funds offer all classes.
The Investor Class is made available to investors directly from American Century Investments and/or through some financial intermediaries. Additional information regarding eligibility for Investor Class shares may be found in the funds’ prospectuses. The I Class is made available to institutional shareholders or through financial intermediaries that provide various shareholder and administrative services. Y Class shares are available through financial intermediaries that offer fee-based advisory programs. The A and C Classes also are made available through financial intermediaries, for purchase by individual investors who receive advisory and personal services from the intermediary. The R Class is made available through financial intermediaries and is generally used in 401(k) and other retirement plans. The R5 and R6 Classes are generally available only to participants in employer-sponsored retirement plans where a financial intermediary provides recordkeeping services to plan participants. G Class shares are available for purchase only by funds advised by American Century Investments and other American Century advisory clients that are subject to a contractual fee for investment management services. The classes have different unified management fees as a result of their separate arrangements for shareholder services. In addition, the A, C and R Class shares each are subject to a separate Master Distribution and Individual Shareholder Services Plan (the A Class Plan, C Class Plan and R Class Plan, respectively and collectively, the plans) described below. The plans have been adopted by the fund’s Board of Trustees in accordance with Rule 12b-1 adopted by the SEC under the Investment Company Act. 
Rule 12b-1 
Rule 12b-1 permits an investment company to pay expenses associated with the distribution of its shares in accordance with a plan adopted by its Board of Trustees and approved by its shareholders. Pursuant to such rule, the Board of Trustees of the funds’ A, C and R Classes have approved and entered into the A Class Plan, C Class Plan and R Class Plan, respectively. The plans are described below.
In adopting the plans, the Board of Trustees (including a majority of trustees who are not interested persons of the funds, as defined in the Investment Company Act, hereafter referred to as the independent trustees) determined that there was a reasonable likelihood that the plans would benefit the funds and the shareholders of the affected class. Some of the anticipated benefits include improved name recognition of the funds generally; and growing assets in existing funds, which helps retain and attract investment management talent, provides a better environment for improving fund performance, and can lower the total expense ratio for funds with stepped-fee schedules. Pursuant to Rule 12b-1, information about revenues and expenses under the plans is presented to the Board of Trustees quarterly. Continuance of the plans must be approved by the Board of Trustees, including a majority of the independent trustees, annually. The plans may be amended by a vote of the Board of Trustees, including a majority of the independent trustees, except that the plans may not be amended to materially increase the amount to be spent for distribution without majority approval of the shareholders of the affected class. The plans terminate automatically in the event of an assignment and may be terminated upon a vote of a majority of the independent trustees or by vote of a majority of the outstanding voting securities of the affected class. 
All fees paid under the plans will be made in accordance with Section 2830 of the Conduct Rules of the Financial Industry Regulatory Authority (FINRA). 
49


The Share Class Plans 
As described in the prospectuses, the A, C and R Class shares of the funds are made available to persons purchasing through broker-dealers, banks, insurance companies and other financial intermediaries that provide various administrative, shareholder and distribution services. In addition, the A, C and R Classes are made available to participants in employer-sponsored retirement plans. The funds’ distributor enters into contracts with various banks, broker-dealers, insurance companies and other financial intermediaries, with respect to the sale of the funds’ shares and/or the use of the funds’ shares in various investment products or in connection with various financial services. 
Certain recordkeeping and administrative services that would otherwise be performed by the funds’ transfer agent may be performed by a plan sponsor (or its agents) or by a financial intermediary for A, C and R Class investors. In addition to such services, the financial intermediaries provide various individual shareholder and distribution services. 
To enable the funds’ shares to be made available through such plans and financial intermediaries, and to compensate them for such services, the funds’ Board of Trustees has adopted the A, C and R Class Plans. Pursuant to the plans, the following fees are paid and described further below. 
A Class
The A Class pays the funds’ distributor 0.25% annually of the average daily net asset value of the A Class shares. The distributor may use these fees to pay for certain ongoing shareholder and administrative services and for distribution services, including past distribution services. This payment is fixed at 0.25% and is not based on expenses incurred by the distributor. 
C Class 
The C Class pays the funds’ distributor 1.00% annually of the average daily net asset value of the funds’ C Class shares, 0.25% of which is paid for certain ongoing individual shareholder and administrative services and 0.75% of which is paid for distribution services, including past distribution services. This payment is fixed at 1.00% and is not based on expenses incurred by the distributor. 
R Class 
The R Class pays the funds’ distributor 0.50% annually of the average daily net asset value of the R Class shares. The distributor may use these fees to pay for certain ongoing shareholder and administrative services and for distribution services, including past distribution services. This payment is fixed at 0.50% and is not based on expenses incurred by the distributor.
During the fiscal year ended October 31, 2022, the aggregate amount of fees paid under each class plan is included in the table below.
  A Class C Class R Class
Emerging Markets Debt $614 $283 $736
Global Bond $3,147 $4,036 $1,309
International Bond $7,697 $871 $248
The distributor then makes these payments to the financial intermediaries (including underwriters and broker-dealers, who may use some of the proceeds to compensate sales personnel) who offer the A, C and R Class shares for the services described below. No portion of these payments is used by the distributor to pay for advertising, printing costs or interest expenses. 
Payments may be made for a variety of individual shareholder services, including, but not limited to: 
(a)providing individualized and customized investment advisory services, including the consideration of shareholder profiles and specific goals;
(b)creating investment models and asset allocation models for use by shareholders in selecting appropriate funds;
(c)conducting proprietary research about investment choices and the market in general;
(d)periodic rebalancing of shareholder accounts to ensure compliance with the selected asset allocation;
(e)consolidating shareholder accounts in one place;
(f)paying service fees for providing personal, continuing services to investors, as contemplated by the Conduct Rules of FINRA; and
(g)other individual services.
Individual shareholder services do not include those activities and expenses that are primarily intended to result in the sale of additional shares of the funds. 
Distribution services include any activity undertaken or expense incurred that is primarily intended to result in the sale of A, C and/or R Class shares, which services may include but are not limited to: 
(a)paying sales commissions, on-going commissions and other payments to brokers, dealers, financial institutions or others who sell the A, C and R Class shares pursuant to selling agreements;
(b)compensating registered representatives or other employees of the distributor who engage in or support distribution of the A, C and R Class shares;
50


(c)compensating and paying expenses (including overhead and telephone expenses) of the distributor;
(d)printing prospectuses, statements of additional information and reports for other-than-existing shareholders;
(e)preparing, printing and distributing sales literature and advertising materials provided to the funds’ shareholders and prospective shareholders;
(f)receiving and answering correspondence from prospective shareholders, including distributing prospectuses, statements of additional information, and shareholder reports;
(g)providing facilities to answer questions from prospective shareholders about fund shares;
(h)complying with federal and state securities laws pertaining to the sale of fund shares;
(i)assisting shareholders in completing application forms and selecting dividend and other account options;
(j)providing other reasonable assistance in connection with the distribution of fund shares;
(k)organizing and conducting sales seminars and payments in the form of transactional and compensation or promotional incentives;
(l)profit on the foregoing; and
(m)such other distribution and services activities as the advisor determines may be paid for by the funds pursuant to the terms of the agreement between the corporation and the funds’ distributor and in accordance with Rule 12b-1 of the Investment Company Act.
Valuation of the Fund’s Securities 
The net asset value (NAV) for each class of each fund is calculated by adding the value of all portfolio securities and other assets attributable to the class, deducting liabilities and dividing the result by the number of shares of the class outstanding. Expenses and interest earned on portfolio securities are accrued daily. 
All classes of the funds except the A Class are offered at their NAV. The A Class of the funds is offered at its public offering price, which is the NAV plus the appropriate sales charge. This calculation may be expressed as a formula: 
Offering Price = NAV/(1 – Sales Charge as a % of Offering Price) 
For example, if the NAV of a fund’s A Class shares is $5.00, the public offering price would be $5.00/(1-4.50%) = $5.24. 
Each fund’s NAV is calculated as of the close of regular trading on the New York Stock Exchange (the NYSE), each day the NYSE is open for business. The NYSE usually closes at 4 p.m. Eastern time. The NYSE typically observes the following holidays: New Year’s Day, Martin Luther King Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Although the fund expects the same holidays to be observed in the future, the NYSE may modify its holiday schedule at any time. 
Debt securities and swap agreements are generally valued using evaluated prices obtained from approved independent pricing services or at the most recent mean of the bid and asked prices provided by investment dealers in accordance with the valuation policies and procedures.
Pricing services will generally provide evaluated prices based on accepted industry conventions, which may require the pricing service to exercise its own discretion. Evaluated prices are commonly derived through utilization of market models that take into consideration various market factors, assumptions, and security characteristics including, but not limited to; trade data, quotations from broker-dealers and active market makers, relevant yield curve and spread data, related sector levels, creditworthiness, trade data or market information on comparable securities and other relevant security-specific information. Pricing services may exercise discretion including, but not limited to; selecting and designing the valuation methodology, determining the source and relevance of inputs and assumptions, and assessing price challenges received from its clients. Pricing services may provide prices when market quotations are not available or when certain pricing inputs may be stale. The use of different models or inputs may result in different pricing services determining a different price for the same security. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size but may consider trades of smaller sizes in their models. The fund may hold or transact in such securities in smaller lot sizes, sometimes referred to as “odd-lots.” Securities may trade at different prices when transacted in different lot sizes. The methods used by the pricing services and the valuations so established are reviewed by the valuation designee under the oversight of the Board of Trustees.
Securities maturing within 60 days of the valuation date may also be valued at cost, plus or minus any amortized discount or premium, unless it is determined, based on established guidelines and procedures, that this would not result in fair valuation of a given security. Other assets and securities for which market quotations or the methods described above are not readily available are valued in good faith in accordance with the valuation designee’s procedures.
Equity securities (including exchange-traded funds) and other equity instruments for which market quotations are readily available are valued at the last reported official closing price or sale price as of the time of valuation. Futures contracts are generally valued at the settlement price as provided by the exchange or clearing corporation. Portfolio securities primarily traded on foreign securities exchanges that are open later than the NYSE are valued at the last sale price reported at the time the NAV is determined.
Trading in securities on European, African and Asian securities exchanges and over-the-counter markets is normally completed at various times before the close of business on each day that the NYSE is open. The advisor typically completes its trading on behalf of
51


the fund in various markets before the NYSE closes for the day. If an event were to occur after the value of a security was established but before the NAV per share was determined that was likely to materially change the NAV, then that security would be valued as determined in accordance with procedures adopted by the Board of Trustees.
Trading of these securities in foreign markets may not take place on every day that the NYSE is open. In addition, trading may take place in various foreign markets and on some electronic trading networks on Saturdays or on other days when the NYSE is not open and on which the funds’ NAVs are not calculated. Therefore, these calculations do not take place contemporaneously with the determination of the prices of many of the portfolio securities used in such calculation, and the value of the funds’ portfolios may be affected on days when shares of the funds may not be purchased or redeemed.
When market quotations are not readily available or are believed by the valuation designee to be unreliable, securities and other assets are valued at fair value as determined in accordance with its policies and procedures.
The value of any security or other asset denominated in a currency other than U.S. dollars is then converted to U.S. dollars at the prevailing foreign exchange rate at the time the fund’s NAV is determined. Securities that are neither listed on a securities exchange nor traded over the counter may be priced using the mean of the bid and asked prices obtained from an independent broker who is an established market maker in the security.
Taxes
Federal Income Tax
Each fund intends to qualify annually as a regulated investment company (RIC) under Subchapter M of the Internal Revenue Code of 1986, as amended (the Code). RICs generally are not subject to federal and state income taxes. To qualify as a RIC a fund must, among other requirements, distribute substantially all of its net investment income and net realized capital gains (if any) to investors each year. If a fund were not eligible to be treated as a RIC, it would be liable for taxes at the fund level on all its income, significantly reducing its distributions to investors and eliminating investors’ ability to treat distributions received from the fund in the same manner in which they were realized by the fund. Under certain circumstances, the Code allows funds to cure deficiencies that would otherwise result in the loss of RIC status, including by paying a fund-level tax. 
To qualify as a RIC, a fund must meet certain requirements of the Code, among which are requirements relating to sources of its income and diversification of its assets. A fund is also required to distribute 90% of its investment company taxable income each year. Additionally, a fund must declare dividends by December 31 of each year equal to at least 98% of ordinary income (as of December 31) and 98.2% of capital gains (as of October 31) to avoid the nondeductible 4% federal excise tax on any undistributed amounts. 
Certain bonds purchased by a fund may be treated as bonds that were originally issued at a discount. Original issue discount represents interest for federal income tax purposes and can generally be defined as the difference between the price at which a security was issued and its stated redemption price at maturity. Although no cash is actually received by a fund until the maturity of the bond, original issue discount is treated for federal income tax purposes as income earned by a fund over the term of the bond, and therefore is subject to the distribution requirements of the Code. The annual amount of income earned on such a bond by a fund generally is determined on the basis of a constant yield to maturity that takes into account the semiannual compounding of accrued interest. 
In addition, some of the bonds may be purchased by a fund at a discount that exceeds the original issue discount on such bonds, if any. This additional discount represents market discount for federal income tax purposes. The gain realized on the disposition of any bond having market discount generally will be treated as taxable ordinary income to the extent it does not exceed the accrued market discount on such bond (unless a fund elects to include market discount in income in tax years to which it is attributable or if the amount is considered de minimis). Generally, market discount accrues on a daily basis for each day the bond is held by a fund on a constant yield to maturity basis. In the case of any debt security having a fixed maturity date of not more than one year from date of issue, the gain realized on disposition generally will be treated as a short-term capital gain. In the case of any debt security having a fixed maturity date of not more than one year from date of issue, the gain realized on disposition generally will be treated as a short-term capital gain. If a fund holds the foregoing kinds of securities, it may be required to pay out as an income distribution each year an amount that is greater than the total amount of cash interest the fund actually received, which distributions may be made from the assets of the fund or, if necessary, by disposition of portfolio securities, including at a time when such disposition may not otherwise be advantageous. 
A fund’s investments in foreign securities may be subject to withholding and other taxes imposed by foreign countries. However, tax conventions between certain countries and the United States may reduce or eliminate such taxes. Any foreign taxes paid by a fund will reduce its dividends distributions to investors. 
A fund’s transactions in foreign currencies, forward contracts, options and futures contracts (including options and futures contracts on foreign currencies) will be subject to special provisions of the Code that, among other things, may affect the character of gains and losses realized by the fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the fund, defer fund losses, and affect the determination of whether capital gains and losses are characterized as long-term or short-term capital gains or losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also may require a fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were
52


sold), which may cause the fund to recognize income without receiving cash with which to make distributions in amounts necessary to satisfy the distribution requirements of the Code for relief from income and excise taxes. A fund will monitor its transactions and may make such tax elections as fund management deems appropriate with respect to these transactions.
Under the Code, gains or losses attributable to fluctuations in exchange rates that occur between the time a fund accrues income or other receivables or accrues expenses or other liabilities denominated in a foreign currency and the time a fund actually collects such receivables or pays such liabilities generally are treated as ordinary income or loss. Similarly, in disposing of debt securities denominated in foreign currencies, certain forward currency contracts, or other instruments, gains or losses attributable to fluctuations in the value of a foreign currency between the date the security, contract, or other instrument is acquired and the date it is disposed of are also usually treated as ordinary income or loss. Under Section 988 of the Code, these gains or losses may increase or decrease the amount of a fund’s investment company taxable income distributed to shareholders as ordinary income. This treatment could increase or decrease a fund’s ordinary income distributions, which may cause some or all of a fund’s previously distributed income to be classified as a return of capital. 
As of October 31, 2022, the funds had the following capital loss carryovers. When a fund has a capital loss carryover, it does not make capital gains distributions until the loss has been offset. The Regulated Investment Company Modernization Act of 2010 allows the funds to carry forward capital losses incurred in future taxable years for an unlimited period.

If you have not complied with certain provisions of the Internal Revenue Code and Regulations, either American Century Investments or your financial intermediary is required by federal law to withhold and remit to the IRS the applicable federal withholding rate of reportable payments (which may include dividends, capital gains distributions and redemption proceeds). Those regulations require you to certify that the Social Security number or tax identification number you provide is correct and that you are not subject to withholding for previous under-reporting to the IRS. You will be asked to make the appropriate certification on your account application. Payments reported by us to the IRS that omit your Social Security number or tax identification number will subject us to a non-refundable penalty of $50, which will be charged against your account if you fail to provide the certification by the time the report is filed. 
If fund shares are purchased through taxable accounts, distributions of either cash or additional shares of net investment income and net short-term capital gains are taxable to you as ordinary income, unless they are designated as qualified dividend income and you meet a minimum required holding period with respect to your shares of a fund, in which case such distributions are taxed at the long-term capital gains tax rate. Qualified dividend income is a dividend received by a fund from the stock of a domestic or qualifying foreign corporation, provided that the fund has held the stock for a required holding period and the stock was not on loan at the time of the dividend. The required holding period for qualified dividend income is met if the underlying shares are held more than 60 days in the 121-day period beginning 60 days prior to the ex-dividend date. Dividends received by a fund on shares of stock of domestic corporations may qualify for the 70% dividends-received deduction when distributed to corporate shareholders to the extent that a fund held those shares for more than 45 days. The funds do not expect a significant portion of their distributions to be qualified dividend income or to qualify for the corporate dividends-received deduction. 
Distributions from gains on assets held by a fund longer than 12 months are taxable as long-term gains regardless of the length of time you have held your shares in the fund. If you purchase shares in a fund and sell them at a loss within six months, your loss on the sale of those shares will be treated as a long-term capital loss to the extent of any long-term capital gains dividends you received on those shares. 
Each fund may use the “equalization method” of accounting to allocate a portion of their earnings and profits to redemption proceeds. Although using this method generally will not affect a fund’s total returns, it may reduce the amount that a fund would otherwise distribute to continuing shareholders by reducing the effect of redemptions of fund shares on fund distributions to shareholders.
A redemption of shares of a fund (including a redemption made in an exchange transaction) will be a taxable transaction for federal income tax purposes and you generally will recognize gain or loss in an amount equal to the difference between the basis of the shares and the amount received. If a loss is realized on the redemption of fund shares, the reinvestment in additional fund shares within 30 days before or after the redemption may be subject to the “wash sale” rules of the Code, resulting in a postponement of the recognition of such loss for federal income tax purposes. 
A 3.8% Medicare contribution tax is imposed on net investment income, including interest, dividends and capital gains, provided you meet specified income levels.

53


State and Local Taxes
Distributions by the funds also may be subject to state and local taxes, even if all or a substantial part of such distributions are derived from interest on U.S. government obligations which, if you received such interest directly, would be exempt from state income tax. However, most but not all states allow this tax exemption to pass through to fund shareholders when a fund pays distributions to its shareholders. You should consult your tax advisor about the tax status of such distributions in your state. 
The information above is only a summary of some of the tax considerations affecting the funds and their U.S. shareholders. No attempt has been made to discuss individual tax consequences. A prospective investor should consult with his or her tax advisors or state or local tax authorities to determine whether the funds are suitable investments. 
Financial Statements
The funds’ financial statements for the fiscal year ended October 31, 2022 have been audited by Deloitte & Touche LLP, independent registered public accounting firm. Their Report of Independent Registered Public Accounting Firm and the financial statements included in the funds’ annual reports for the fiscal year ended October 31, 2022, are incorporated herein by reference.

A shareholder owning beneficially more than 25% of the trust’s outstanding shares may be considered a controlling person. The vote of any such person could have a more significant effect on matters presented at a shareholders’ meeting than votes of other shareholders. Although AC Retirement Date Trust is the record owner of more than 25% of the shares of the trust, it is not a control person because it is not a beneficial owner of such shares. As of January 31, 2023, the officers and trustees of the funds, as a group, owned less than 1% of any class of the funds’ outstanding shares.

Appendix B – Sales Charges and Payments to Dealers 
Sales Charges 
The sales charges applicable to the A and C Classes of the funds are described in the prospectuses for those classes in the section titled Investing Through a Financial Intermediary. Shares of the A Class are subject to an initial sales charge, which declines as the amount of the purchase increases. Additional information regarding reductions and, if applicable, waivers of the sales charges may be found in the funds’ prospectuses.
Shares of the A and C Classes are subject to a contingent deferred sales charge (CDSC) upon redemption of the shares in certain circumstances. The specific charges and when they apply are described in the relevant prospectuses. The CDSC may be waived for certain redemptions by some shareholders, as described in the prospectuses. 
An investor may terminate his relationship with an intermediary at any time. If the investor does not establish a relationship with a new intermediary and transfer any accounts to that new intermediary, such accounts may be exchanged to the Investor Class of the fund, if such class is available. The investor will be the shareholder of record of such accounts. In this situation, any applicable CDSCs will be charged when the exchange is made. 
During the last full fiscal year ended October 31, 2022, the funds had no CDSCs paid to the distributor from the A Class and C Class shares.
Payments to Dealers 
The funds’ distributor expects to pay dealer commissions to the financial intermediaries who sell A and/or C Class shares of the funds at the time of such sales. Payments for A Class shares will be as follows 
Purchase Amount Dealer Commission as a % of Offering Price
< $99,999 4.00%
$100,000 - $249,999 3.00%
$250,000 - $499,999 2.00%
$500,000 - $999,999 1.75%
$1,000,000 - $3,999,999 0.75%
$4,000,000 - $9,999,999 0.50%
> $10,000,000 0.25%
 
No dealer commission will be paid on purchases by employer-sponsored retirement plans. For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs. Payments will equal 1.00% of the purchase price of the C Class shares sold by the financial intermediary. The distributor will retain the 12b-1 fee paid by the C Class of funds for the first 12 months after the shares are purchased. This fee is intended in part to permit the distributor to recoup a portion of ongoing sales commissions to dealers plus financing costs, if any. Beginning with the first day of the 13th month, the distributor will make the C Class distribution and individual shareholder services fee payments described above to the financial intermediaries involved on a quarterly basis. In addition, C Class purchases, and A Class purchases greater than $1,000,000 are subject to a CDSC as described in the prospectuses.
From time to time, the distributor may make additional payments to dealers, including but not limited to payment assistance for conferences and seminars, provision of sales or training programs for dealer employees and/or the public (including, in some cases, payment for travel expenses for registered representatives and other dealer employees who participate), advertising and sales campaigns about a fund or funds, and assistance in financing dealer-sponsored events. Other payments may be offered as well, and all such payments will be consistent with applicable law, including the then-current rules of the Financial Industry Regulatory Authority. Such payments will not change the price paid by investors for shares of the funds.

B-1


Appendix C – Buying and Selling Fund Shares 
Information about buying, selling, exchanging and, if applicable, converting fund shares is contained in the funds’ prospectuses. The prospectuses are available to investors without charge and may be obtained by calling us. 
Employer-Sponsored Retirement Plans 
Certain group employer-sponsored retirement plans that hold a single account for all plan participants with the fund, or that are part of a retirement plan or platform offered by banks, broker-dealers, financial advisors or insurance companies, or serviced by retirement recordkeepers are eligible to purchase Investor, A, C, R, R5 and R6 Class shares. Employer-sponsored retirement plans are not eligible to purchase I or Y Class shares. A and C Class purchases are available at net asset value with no dealer commission paid to the financial professional and do not incur a CDSC. A, C and R Class shares purchased in employer-sponsored retirement plans are subject to applicable distribution and service (12b-1) fees, which the financial intermediary begins receiving immediately at the time of purchase. American Century Investments does not impose minimum initial investment amount, plan size or participant number requirement by class for employer-sponsored retirement plans; however, financial intermediaries or plan recordkeepers may require plans to meet different requirements. 
Examples of employer-sponsored retirement plans include the following: 
401(a) plans
pension plans
profit sharing plans
401(k) plans (including plans with a Roth 401(k)
feature, SIMPLE 401(k) plans and Solo 401(k) plans
money purchase plans
target benefit plans
Taft-Hartley multi-employer pension plans
SERP and “Top Hat” plans
ERISA trusts
employee benefit plans and trusts
employer-sponsored health plans
457 plans
KEOGH or HR(10) plans
employer-sponsored 403(b) plans
(including plans with a Roth 403(b) feature)
nonqualified deferred compensation plans
nonqualified excess benefit plans
nonqualified retirement plans
