It invests in MBS, issued or guaranteed by a United States Government-sponsored entity (GSE), such as the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac), or a government agency such as Government National Mortgage Administration (Ginnie Mae) (collectively, Agency Securities). Its Agency Securities consist of fixed rate loans. The Company is managed by ARMOUR Capital Management LP, an investment advisor.
