AIBAX Investment Objective and Strategy
Intermediate Bond Fund of America describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Intermediate Bond Fund of America.
Investment objective
The funds investment objective is to provide you with current income consistent with the maturity and quality standards described in this prospectus and preservation of capital.
Principal investment strategy
The fund will invest at least 80% of its assets in bonds (bonds include any debt instrument and money market instrument) which may be represented by other investment instruments, including derivatives. The fund maintains a portfolio of bonds, other debt securities and money market instruments having a dollar-weighted average effective maturity of no less than three years and no greater than five years under normal market conditions. The fund invests primarily in bonds and other debt securities with quality ratings of A or better or A3 or better (by a Nationally Recognized Statistical Rating Organization designated by the funds investment adviser) or unrated but determined to be of equivalent quality by the funds investment adviser. The fund may invest up to 10% of its assets in bonds and other debt securities rated in the BBB or Baa rating category (by a Nationally Recognized Statistical Rating Organization designated by the funds investment adviser) or unrated but determined to be of equivalent quality by the funds investment adviser.
The fund primarily invests in debt securities denominated in U.S. dollars. These include securities issued and guaranteed by the U.S. government, debt securities and mortgage-backed securities issued by government-sponsored entities and federal agencies, and instrumentalities that are not backed by the full faith and credit of the U.S. government. In addition, the fund may invest in mortgage-backed securities issued by private issuers and asset-backed securities (securities backed by assets such as auto loans, credit card receivables or other providers of credit). The fund may invest in inflation-linked bonds issued by U.S. and non-U.S. governments, their agencies or instrumentalities, and corporations. Inflation-linked bonds are structured to protect against inflation by linking the bonds principal and interest payments to an inflation index, such as the Consumer Price Index for Urban Consumers, so that principal and interest adjust to reflect changes in the index.
The fund may also invest in certain derivative instruments, such as futures contracts and swaps. A derivative is a financial contract, the value of which is based on the value of an underlying financial asset (such as a stock, bond or currency), a reference rate or a market index. The fund may invest in a derivative only if, in the opinion of the investment adviser, the expected risks and rewards of the proposed investment are consistent with the investment objective and strategies of the fund as disclosed in this prospectus and in the funds statement of additional information. The investment adviser uses a system of multiple portfolio managers in managing the funds assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers who decide how their respective segments will be invested.
The fund relies on the professional judgment of its investment adviser to make decisions about the funds portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively priced securities that, in its opinion, represent good investment opportunities. The investment adviser believes that an important way to accomplish this is by analyzing various factors, which may include the credit strength of the issuer, prices of similar securities issued by comparable issuers, anticipated changes in interest rates, general market conditions and other factors pertinent to the particular security being evaluated. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.
