Fidelity GNMA Fund 

This fund primarily allocates at least 80% of its holdings to Ginnie Mae securities, encompassing direct investments and those facilitated by repurchase agreements. Additionally, it diversifies into various other U.S. government debt instruments and related financial vehicles. A segment of its investments includes U.S. government-backed securities originating from entities chartered or sponsored by Congress, distinct from those directly issued or guaranteed by the U.S. Treasury Department. The fund's objective is to maintain an overall interest rate sensitivity comparable to the Bloomberg Barclays GNMA Index.
