The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Government Credit Index covers U.S. dollar denominated, investment grade, fixed-rate securities, which include U.S. Treasury and government-related, corporate, credit and agency fixed-rate debt securities.

The Portfolio also may use financial instruments such as futures and options to manage duration. Duration measures the sensitivity of the value of a bond or bond portfolio to changes in interest rates. Typically, a bond portfolio with a low (short) duration means that its value is less sensitive to interest rate changes, while bond portfolios with a high (long) duration are more sensitive. The Portfolio may invest up to 50% of its assets in derivatives. It is anticipated that the Portfolio's derivative instruments will consist primarily of forward contracts, exchange-traded futures and options contracts on individual securities or securities indices, but the Portfolio also may utilize other types of derivatives. The Portfolio's investments in derivatives may be deemed to involve the use of leverage because the Portfolio is not required to invest the full market value of the contract upon entering into the contract but participates in gains and losses on the full contract price. The use of derivatives also may be deemed to involve the use of leverage because the heightened price sensitivity of some derivatives to market changes may magnify the Portfolio's gain or loss. </font></p></div> </div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.
