AGNC Investment Corp. is a real estate investment trust (REIT) that focuses on leveraged investments in Agency residential mortgage backed securities (RMBS), that includes residential mortgage pass-through securities and collateralized mortgage obligations. Importantly, for them, a U.S. Government agency or a U.S. Government-sponsored enterprise (GSE) guarantees the principal and interest payments. The company's investment may also comprise Agency debenture securities, which are issued by Freddie Mac and Fannie Mae, as well as other assets that are convincingly associated with Agency securities. The company purchases single-family residential pass-through securities, which are interests in pooled loans of principal and interest including pre-paid principal that are made to the holders of the notes.
