(a)

Includes unrealized gains and losses for residential mortgage investments classified as available-for-sale (see NOTE 8).

(b)

Net WAC, or weighted average coupon, is the weighted average interest rate of the mortgage loans underlying the indicated investments net of servicing and other fees as of the indicated balance sheet date. Net WAC is expressed as a percentage calculated on an annualized basis on the unpaid principal balances of the mortgage loans underlying these investments. Average yield is presented for the quarter then ended, and is based on the cash component of interest income expressed as a percentage calculated on an annualized basis on average amortized cost basis (the "cash yield") less the effects of amortizing investment premiums. Investment premium amortization is determined using the interest method and incorporates actual and anticipated future mortgage prepayments.

Agency Securities are considered to have limited, if any, credit risk, particularly in light of the conservatorship of the GSEs by the federal government in 2008. Residential mortgage loans held by the Company were originated prior to 1995 when Capstead operated a mortgage conduit and the related credit risk is borne by the Company. Collateral for structured financings consists of private residential mortgage securities obtained through the above-mentioned mortgage conduit that are pledged to secure repayment of the structured financings. The credit risk for these securities is borne by the related bondholders. The maturity of mortgage securities is directly affected by prepayments of principal on the underlying mortgage loans. Consequently, the actual maturity of Residential mortgage investments will be significantly shorter than the portfolio's weighted average contractual maturity of 291 months.

Fixed-rate investments consist of residential mortgage loans and Agency Securities backed by residential mortgage loans with fixed rates of interest. Adjustable-rate investments generally are ARM Agency Securities backed by residential mortgage loans that have coupon interest rates that adjust at least annually to more current interest rates or begin doing so after an initial fixed-rate period. After the initial fixed-rate period, if applicable, mortgage loans underlying ARM securities either (i) adjust annually based on specified margins over the one-year Constant Maturity U.S. Treasury Note Rate ("CMT") or the one-year London interbank offered rate ("LIBOR"), (ii) adjust semiannually based on specified margins over six-month LIBOR, or (iii) adjust monthly based on specified margins over indices such as one-month LIBOR, the Eleventh District Federal Reserve Bank Cost of Funds Index, or over a rolling twelve month average of the one-year CMT index, usually subject to periodic and lifetime limits, or caps, on the amount of such adjustments during any single interest rate adjustment period and over the contractual term of the underlying loans.

Capstead classifies its ARM securities based on each security's average number of months until coupon reset ("months to roll"). Months to roll is an indicator of asset duration which is a measure of market price sensitivity to interest rate movements. Current-reset ARM securities have months to roll of less than 18 months while longer-to-reset ARM securities have months to roll of 18 months or greater. As of March 31, 2012, the average months to roll for the Company's $8.55 billion (basis) in current-reset ARM securities was 5.2 months while the average months-to-roll for the Company's $4.18 billion (basis) in longer-to-reset ARM securities was 45.7 months.

In October 2009, under variable interest entity accounting rules, the Company began consolidating two townhome developments in the Dallas, Texas area that were collateral for subordinated loans made by the Company. In November 2011, the Company completed foreclosure proceedings, assuming ownership of the underlying collateral. As of March 31, 2012, the Company's remaining investment consisted of seven unsold completed units with a basis of $1.8 million that is included in Receivables and other assets on the balance sheet. Included in Miscellaneous other revenue (expense) are $101,000 and $103,000 of related operating costs, net of gains on unit sales, incurred during the quarters ended March 31, 2012 and 2011, respectively. The Company remains a subordinated participant in the lending group to the Four Seasons resort in Nevis, West Indies which was foreclosed on in May 2010. The resort closed in October 2008 after sustaining hurricane damage and reopened in December 2010. The Company wrote off its $39.2 million investment in December 2009. A recovery on this investment of any amount would come from the eventual disposition of the resort by the lending group which may not occur for several years.
