Investment objective

Principal investment strategy
The fund invests at least 65% of its assets in investment-grade, non-money market debt securities. An investment-grade security is one that has been rated by a nationally recognized statistical rating organization in its top four credit quality categories or determined by the advisor to be of comparable credit quality. Debt securities include fixed-income investments such as notes, bonds, commercial paper and U.S. Treasury securities. These securities, which may be payable in U.S. or foreign currencies, may include corporate bonds and notes, government securities and securities backed by mortgages or other assets. The fund may invest in high-yield debt securities. A high-yield security, or junk bond, 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 also invest in securities issued by companies that are located in emerging market countriesemerging market securities. The fund may not invest more than 35% of its assets in high-yield securities and emerging market securities combined. The fund may invest in non-dollar denominated debt securities. The weighted average maturity of the funds portfolio must be 3 years or longer. 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. 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) 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. In addition to the debt securities described above, the fund may also invest in bank loans. The fund also may invest in derivative instruments provided that such investments are in keeping with the funds investment objectives. Such derivative instruments may include options, futures contracts, options on futures contracts, and swap agreements (including, but not limited to, credit default swap agreements). The fund may invest in collateralized debt obligations, including collateralized loan obligations and collateralized mortgage obligations, mortgage- or asset- backed securities, and other similarly structured investments. The fund may use foreign currency exchange contracts to shift investment exposure from one currency into another for hedging purposes or to enhance returns.
To determine whether to buy or sell a security, the portfolio managers consider, among other things, various fund requirements and standards, along with economic conditions, alternative investments and interest rates. To gain exposure to certain segments of the fixed-income market, the fund may invest in other American Century funds (affiliated funds). The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. This may cause higher transaction costs and may affect performance. It may also result in the realization and distribution of capital gains.
