PART I

ITEM 1. BUSINESS.

Capstead Mortgage Corporation (together with its subsidiaries, “Capstead” or the “Company”) formed in 1985 and based in Dallas, Texas, is a self-managed real estate investment trust (“REIT”) for federal income tax purposes. Capstead’s core strategy is managing a leveraged portfolio of residential mortgage securities consisting almost exclusively of 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. Capstead may also augment its core portfolio with investments in credit-sensitive commercial real estate-related assets.

For further discussion of the Company’s business and financial condition, see the Registrant’s Annual Report to Stockholders for the year ended December 31, 2007 on pages 31 through 54, which is incorporated herein by reference.

Other Investment Strategies

The Company may enter into other short- or long-term investment strategies as the opportunities arise.

Competition

In purchasing residential mortgage investments and commercial real estate-related assets, the Company competes with others in the real estate and banking industries including REITs, savings banks, commercial banks, mortgage and investment bankers, private equity funds, conduits, insurance companies, other lenders, other real estate investors and mutual funds.

Regulation and Related Matters

Operating as a REIT that primarily invests in financial assets subjects the Company to various federal regulatory requirements.
