Fidelity SAI Long-Term Treasury Bd Idx (FBLTX)

The fund normally invests at least 80% of assets in securities included in the Bloomberg U.S. 20+ Year Treasury Bond Index. It normally maintains a dollar-weighted average maturity that is generally expected to be 20 years or more, consistent with that of the index. The advisor uses statistical sampling techniques based on duration, maturity, interest rate sensitivity, security structure, and credit quality to attempt to replicate the returns of the Bloomberg U.S. 20+ Year Treasury Bond Index using a smaller number of securities.
