The Fund, under normal circumstances, invests at least 90% of its assets in bond securities that are held in the Index. In pursuing its objective, and its investment methodology, the Fund may engage in active portfolio trading. The Fund may at times purchase or sell futures contracts on fixed-income securities, interest rates, and fixed-income securities indices in lieu of investing directly in fixed-income securities. The Fund might do so, for example, in order to adjust the interest-rate sensitivity of the Fund to bring it more closely in line with that of the Bloomberg U.S. Aggregate Bond Index*. It might also do so to increase its investment exposure pending investment of cash in the bonds comprising the Index or to reduce its investment exposure in situations where it intends to sell a portion of the securities in its portfolio but the sale has not yet been completed. * Bloomberg U.S. Aggregate Bond Index is a trademark of Bloomberg Bank PLC and has been licensed for use in connection with the management of the Fund.
