Fund Goal and Approach
The fund seeks to match the total return of the Barclays U.S. Aggregate Index.To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in bonds that are included in the Barclays U.S. Aggregate Index (or other instruments with similar economic characteristics). In seeking to match index performance, the manager uses a passive management approach and purchases all or a representative sample of the bonds comprising the Barclays U.S. Aggregate Index. Because the fund has expenses, performance will tend to be slightly lower than that of the index. To maintain liquidity, the fund may invest up to 20% of its assets in various short-term, fixed-income securities and money market instruments. The fund attempts to have a correlation between its performance and that of the Barclays U.S. Aggregate Index of at least .95 before expenses. A correlation of 1.00 would mean that the fund and the index were perfectly correlated.
The fund's investments are selected by a "sampling" process, which is a statistical process used to select bonds so that the fund has investment characteristics that closely approximate those of the index. By using this sampling process, the fund typically will not invest in all of the securities in the index.
The Barclays U.S. Aggregate Index is a broad-based, unmanaged index that covers the U.S. dollar-denominated, investment grade (Baa/BBB or higher), fixed-rate, taxable bond market of SEC-registered securities. The index includes bonds from the U.S. Treasury, U.S. government-related, corporate, mortgage-backed securities, asset-backed securities and commercial mortgage-backed securities sectors. Although most of the securities in the index are issued by the U.S. Treasury and other U.S. government and agency issuers, the index may include dollar-denominated bonds issued by foreign issuers in which the fund may invest to the extent the index contains such securities. Barclays is not affiliated with the fund, and it does not sell or endorse the fund, nor does it guarantee the performance of the fund or the index.
The fund is subject generally to interest rate, credit, liquidity, prepayment and extension risk (as to mortgage-related holdings), call, sector, and market risks, to varying degrees, all of which are more fully described in the funds prospectus.
Generally, all other factors being equal, bond prices are inversely related to interest-rate changes and rate increases can cause price declines.
Because the fund uses an indexing strategy, it does not attempt to manage market volatility, use defensive strategies or reduce the effects of any long-term periods of poor performance among bonds.
The correlation between fund and index performance may be affected by the funds expenses and use of sampling techniques, changes in securities markets, changes in the composition of the index and the timing of purchases and redemptions of fund shares.
Investors should consider the investment objectives, risks, charges, and expenses of the fund carefully before investing. Download a prospectus, or a summary prospectus, if available, that contains this and other information about the fund, and read it carefully before investing.
