Capstead Mortgage Corporation Security Rating

Capstead Mortgage Corporation operates as a self-managed real estate investment trust for federal income tax purposes. The Company's investment strategy involves managing a leveraged portfolio of residential mortgage pass-through securities consisting almost exclusively of relatively short-duration adjustable-rate mortgage (“ARM”) securities issued and guaranteed by government-sponsored enterprises, either Fannie Mae or Freddie Mac, or by an agency of the federal government, Ginnie Mae. Residential mortgage pass-through securities guaranteed by Fannie Mae, Freddie Mac or Ginnie Mae, referred to as “Agency Securities,” are considered to have limited, if any, credit risk because of federal government support.
