C000023911 Investment Objective and Strategy
Ultra-Short Bond Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by American Funds Insurance Series.
Investment objective
The investment objective of the fund is to provide current income, consistent with the maturity and quality standards applicable to the fund, and preservation of capital and liquidity.
Principal investment strategy
Normally, the fund invests at least 80% of its assets in bonds and other debt securities. The fund invests substantially in short-term government securities and high-quality money market instruments, such as commercial paper, commercial bank obligations and ultra-short-term debt securities. The fund maintains a dollar-weighted average portfolio maturity of 60 days or less. The fund may enter into repurchase agreements that are fully collateralized by cash or government securities. When it enters into a repurchase agreement, the fund purchases a security from a bank or broker-dealer and obtains a simultaneous commitment from the seller to repurchase the security at a specified time and price. Because the security purchased by the fund constitutes collateral for the sellers repurchase obligation, a repurchase agreement is effectively a loan by the fund that is collateralized by the security purchased.
The fund will only enter into repurchase agreements involving securities of the type (excluding any maturity limitations) in which it could otherwise invest. The fund may invest in securities issued by entities domiciled outside the United States and securities with credit and liquidity support features provided by entities domiciled outside the United States. The fund may also invest in securities of U.S. issuers with substantial operations outside the United States. 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 provide current income while preserving capital and maintaining liquidity.
