About Capstead

Capstead Mortgage Corporation, formed in 1985 and based in Dallas, Texas, is a self-managed real estate investment trust for federal income tax purposes. Capstead’s core investment strategy is managing a leveraged portfolio of residential mortgage pass-through securities consisting almost exclusively of adjustable-rate, or ARM, securities issued and guaranteed by government-sponsored entities, either Fannie Mae or Freddie Mac, or by an agency of the federal government, Ginnie Mae. Agency-guaranteed residential mortgage securities carry an implied AAA credit rating with limited, if any, credit risk.

Forward-looking Statements

Reports and correspondence issued by the Company may contain "forward-looking statements” (within the meaning of the Private Securities Litigation Reform Act of 1995) that inherently involve risks and uncertainties. Capstead’s actual results and liquidity can differ materially from those anticipated in these forward-looking statements because of changes in the level and composition of the Company’s investments and other factors. As discussed in the Company’s filings with the Securities and Exchange Commission, these factors may include, but are not limited to, changes in general economic conditions, the availability of suitable qualifying investments from both an investment return and regulatory perspective, the availability of new investment capital, the availability of financing at reasonable levels and terms to support investing on a leveraged basis, fluctuations in interest rates and levels of mortgage prepayments, deterioration in credit quality and ratings, the effectiveness of risk management strategies, the impact of differing levels of leverage employed, liquidity of secondary markets and credit markets, increases in costs and other general competitive factors. In addition to the above considerations, actual results and liquidity related to investments in loans secured by commercial real estate are affected by borrower performance, changes in general as well as local economic conditions and real estate markets, increases in competition and inflationary pressures, changes in the tax and regulatory environment including zoning and environmental laws, uninsured losses or losses in excess of insurance limits and the availability of adequate insurance coverage at reasonable costs, among other factors.
