Fidelity Inflation-Protected Bond Index Fund 

The fund normally invests at least 80% of assets in inflation-protected debt securities included in the Bloomberg Barclays U.S. Treasury Inflation-Protected Securities (TIPS) Index (Series-L). It engages in transactions that have a leveraging effect on the fund, including investments in derivatives - such as swaps (interest rate, total return, and credit default) and futures contracts - and forward-settling securities, to adjust the fund's risk exposure.
