Fidelity Inflation-Protected Bond Index Fund 

This fund aims to mirror the performance of the Bloomberg Barclays U.S. Treasury Inflation-Protected Securities (TIPS) Index (Series-L). To achieve this objective, it typically allocates at least 80% of its total assets to inflation-protected debt instruments. Additionally, the fund utilizes various financial tools that can amplify its portfolio's exposure, such as derivatives—including interest rate, total return, and credit default swaps, as well as futures contracts—and forward-settling securities, all employed to fine-tune its overall risk profile.
