Fidelity Long-Term Treasury Bond Index Fund (FNBGX)

The fund generally commits a minimum of 80% of its assets to the debt instruments that constitute the Bloomberg U.S. Long Treasury Bond Index. Its portfolio typically features a dollar-weighted average maturity of ten years or more, aligning with the characteristics of its benchmark index. To replicate the returns of the Bloomberg U.S. Long Treasury Bond Index using a more focused selection of securities, the advisor employs sophisticated statistical sampling techniques. These techniques are informed by factors including duration, maturity, sensitivity to interest rate changes, the underlying structure of the bonds, and their credit quality.
