Strategy. To pursue its goal, the fund generally invests in securities that are included in the Bloomberg US 1-5 Year Corporate Bond Index . The index measures the performance of U.S. investment grade, taxable corporate bonds with maturities greater than or equal to one year and less than five years that have $300 million or more of outstanding face value. The securities in the index must be denominated in U.S. dollars and must be fixed-rate. The index includes securities publicly issued by U.S. and non-U.S. industrial, utility and financial issuers. The index excludes certain types of securities, including contingent capital securities, inflation-linked bonds, floating-rate issues, taxable and tax-exempt municipal securities, and structured notes.

The index measures the performance of U.S. investment grade, taxable corporate bonds with maturities greater than or equal to one year and less than five years that have $300 million or more of outstanding face value. The securities in the index must be denominated in U.S. dollars and must be fixed-rate. The index includes securities publicly issued by U.S. and non-U.S. industrial, utility and financial issuers. The index excludes certain types of securities, including contingent capital securities, inflation-linked bonds, floating-rate issues, taxable and tax-exempt municipal securities, and structured notes. The index is market capitalization weighted and the securities in the index are updated on the last business day of each month. It is the funds policy that under normal circumstances it will invest at least 90% of its net assets (including, for this purpose, any borrowings for investment purposes) in securities included in the index. The fund will notify its shareholders at least 60 days before changing this policy. Under normal circumstances, the fund may invest up to 10% of its net assets in securities not included in its index. The principal types of these investments include those that the investment adviser believes will help the fund track the index, such as investments in (a) securities that are not represented in the index but the investment adviser anticipates will be added to the index; (b) high-quality liquid investments, such as securities issued by the U.S. government, its agencies or instrumentalities, including obligations that are not guaranteed by the U.S. Treasury, and obligations that are issued by private issuers; (c) other investment companies; and (d) derivatives, principally futures contracts. The fund may use futures contracts and other derivatives primarily to help manage interest rate exposure. The fund may also invest in cash and cash equivalents, including money market funds, and lend its securities to minimize the difference in performance that naturally exists between an index fund and its corresponding index. Because it may not be possible or practical to purchase all of the securities in the index, the funds investment adviser will seek to track the total return of the index by using sampling techniques. Sampling techniques involve investing in a limited number of index securities that, when taken together, are expected to perform similarly to the index as a whole. These techniques are based on a variety of factors, including interest rate and yield curve risk, maturity exposures, industry, sector and issuer weights, credit quality, and other risk factors and characteristics. The fund expects that its portfolio will hold less than the total number of securities in the index, but reserves the right to hold as many securities as it believes Index ownership Bloomberg and Bloomberg US 1-5 Year Corporate Bond Index are service marks of Bloomberg Finance L.P. and its affiliates, including Bloomberg Index Services Limited (BISL), the administrator of the indices (collectively, Bloomberg).

The fund may sell securities that are represented in the index in anticipation of their removal from the index. The fund generally expects that its maturity will be similar to that of the index. In addition, the fund generally expects that its weighted average duration will closely correspond to the weighted average duration of the index, which as of December 31, 2024, was 2.50 years. The fund will concentrate its investments (i.e., hold more than 25% of its total assets) in a particular industry, group of industries or sector to approximately the same extent that its index is so concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.
