NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

MARCH 31, 2015

(unaudited)

NOTE 1 ¾ BUSINESS

Capstead Mortgage Corporation operates as a self-managed real estate investment trust for federal income tax purposes (a “REIT”) and is based in Dallas, Texas.  Unless the context otherwise indicates, Capstead Mortgage Corporation, together with its subsidiaries, is referred to as “Capstead” or the “Company.”  Capstead earns income from investing in a leveraged portfolio of residential mortgage pass-through securities consisting almost exclusively of adjustable-rate mortgage (“ARM”) securities issued and guaranteed by government-sponsored enterprises, either Fannie Mae or Freddie Mac (together, the “GSEs”), or by an agency of the federal government, Ginnie Mae.  Residential mortgage pass-through securities guaranteed by the GSEs or Ginnie Mae are referred to as “Agency Securities” and are considered to have limited, if any, credit risk.

NOTE 2 ¾ BASIS OF PRESENTATION

Interim Financial Reporting and Reclassifications

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.  In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.  Operating results for the quarter ended March 31, 2015 are not necessarily indicative of the results that may be expected for the calendar year ending December 31, 2015.  For further information refer to the audited consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2014.

Recent Accounting Pronouncements

In June 2014 the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-11, Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings and Disclosures (“ASU 2014-11”).  ASU 2014-11 requires repurchase-to-maturity transactions to be accounted for as financings and eliminates existing guidance regarding so-called “linked transactions” between a buyer of securities and a seller that also provides related repurchase financings.  ASU 2014-11 also introduces new disclosure requirements and is effective for periods beginning after December 15, 2014.  The Company adopted ASU 2014-11 in the current quarter.  As the Company has not entered into any repurchase-to-maturity or linked transactions, the provisions of this ASU had no effect on the Company’s results of operations, financial condition, or cash flows.

NOTE 3 ¾ NET INCOME PER COMMON SHARE

Basic net income per common share is computed by dividing net income, after deducting dividends paid or accrued on preferred stock and allocating earnings to equity awards deemed to be participating securities pursuant to the two-class method, by the weighted average number of shares of common stock outstanding, calculated excluding unvested stock awards.  Participating securities include any unvested equity awards that contain non-forfeitable rights to dividends prior to vesting.

-7-

Diluted net income per common share is computed by dividing the numerator used to compute basic net income per common share by the denominator used to compute basic net income per common share, further adjusted for the dilutive effect, if any, of equity awards and shares of preferred stock when and if convertible into shares of common stock.  Shares of the Company’s 7.50% Series E Cumulative Redeemable Preferred Stock are contingently convertible into shares of common stock only upon the occurrence of a change in control and therefore are not considered dilutive securities absent such an occurrence.  Any unvested equity awards that are deemed participating securities are included in the calculation of diluted net income per common share, if dilutive, under either the two-class method or the treasury stock method, depending upon which method produces the more dilutive result.

Components of the computation of basic and diluted net income per common share were as follows for the indicated periods (dollars in thousands, except per share amounts):

(a) Includes unrealized gains and losses for residential mortgage investments classified as available-for-sale (see NOTE 9).

(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.

Because of federal government support for the GSEs, Agency Securities are considered to have limited, if any, credit risk.  Residential mortgage loans held by Capstead were originated prior to 1995 when the Company operated a mortgage conduit and the related credit risk is borne by the Company.  Collateral for structured financings consists of private residential mortgage securities that are backed by loans obtained through this mortgage conduit and are pledged to secure repayment of related structured financings.  Credit risk for these securities is borne by the related bondholders.  The maturity of Residential mortgage investments is directly affected by prepayments of principal on the underlying mortgage loans.  Consequently, actual maturities will be significantly shorter than the portfolio’s weighted average contractual maturity of 290 months.

-9-

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 typically 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 investments based on 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.  A shorter duration generally indicates less interest rate risk.  Current-reset ARM investments have months to roll of less than 18 months while longer-to-reset ARM investments have months to roll of 18 months or greater.  As of March 31, 2015, the average months to roll for the Company’s $7.85 billion (amortized cost basis) in current-reset ARM investments was 6.3 months while the average months to roll for the Company’s $6.03 billion (amortized cost basis) in longer-to-reset ARM investments was 40.0 months.

NOTE 5 ¾ REPURCHASE ARRANGEMENTS AND SIMILAR BORROWINGS

Capstead pledges its Residential mortgage investments as collateral under repurchase arrangements with commercial banks and other financial institutions, referred to as counterparties, the terms and conditions of which are negotiated on a transaction-by-transaction basis when each such borrowing is initiated or renewed.  Repurchase arrangements entered into by the Company involve the sale and a simultaneous agreement to repurchase the transferred assets at a future date and are accounted for as borrowings.  The Company maintains the beneficial interest in the specific securities pledged during the term of each repurchase arrangement and receives the related principal and interest payments.  The amount borrowed is generally equal to the fair value of the securities pledged, as determined by the lending counterparty, less an agreed-upon discount, referred to as a “haircut.”  Interest rates on these borrowings are fixed based on prevailing rates corresponding to the terms of the borrowings, and interest is paid at the termination of the repurchase arrangement at which time the Company may enter into a new repurchase arrangement at prevailing haircuts and rates with the same counterparty or repay that counterparty and negotiate financing with a different counterparty.  None of the Company’s counterparties are obligated to renew or otherwise enter into new repurchase arrangements at the conclusion of existing repurchase arrangements. In response to declines in fair value of pledged securities due to changes in market conditions or the publishing of monthly security paydown factors, lenders typically require the Company to post additional securities as collateral, pay down borrowings or fund cash margin accounts with the counterparties in order to re-establish the agreed-upon collateral requirements.  These actions are referred to as margin calls.  Conversely, in response to increases in fair value of pledged securities, the Company routinely margin calls its lending counterparties in order to have previously pledged collateral returned to the Company.

-10-

Repurchase arrangements and similar borrowings (and related pledged collateral, including accrued interest receivable), classified by collateral type and remaining maturities, and related weighted average borrowing rates as of the indicated dates were as follows (dollars in thousands):

Collateral Type	Collateral Carrying Amount		Accrued Interest Receivable		Borrowings Outstanding		Average Borrowing Rates
March 31, 2015
Borrowings with maturities of 30 days or less:

Year-end borrowing rates adjusted for effects of related Derivatives held as cash flow hedges								0.58

* The maturity of structured financings is directly affected by prepayments on the related mortgage pass-through securities pledged as collateral.  Additionally, these financings are subject to redemption by the residual bondholders.

Average borrowings outstanding differed from respective quarter-end balances during the indicated periods primarily due to changes in portfolio levels and differences in the timing of portfolio acquisitions relative to portfolio runoff as illustrated below (dollars in thousands):

	Quarter Ended
	March 31, 2015					December 31, 2014

NOTE 6 ¾ USE OF DERIVATIVE FINANCIAL INSTRUMENTS, OFFSETTING DISCLOSURES AND CHANGES IN OTHER COMPREHENSIVE INCOME BY COMPONENT

To help mitigate exposure to higher interest rates, Capstead typically uses currently-paying and forward-starting, one-month LIBOR-indexed, pay-fixed, receive-variable, interest rate swap agreements that require interest payments for two-year terms.  These Derivatives are designated as cash flow hedges of the variability of the underlying benchmark interest rate of current and forecasted 30- to 90-day borrowings under repurchase arrangements.  This hedge relationship establishes a relatively stable fixed rate on related borrowings because the variable-rate payments received on the swap agreements offset a significant portion of the interest accruing on the related borrowings, leaving the fixed-rate swap payments as the Company’s effective borrowing rate, subject to certain adjustments.  These adjustments include differences between variable-rate payments received on the swap agreements and related unhedged borrowing rates as well as the effects of measured hedge ineffectiveness.  Additionally, changes in fair value of these Derivatives tend to partially offset opposing changes in fair value of the Company’s residential mortgage investments that can occur in response to changes in market interest rates.

During the quarter ended March 31, 2015 Capstead entered into swap agreements with notional amounts of $700 million.  These swap agreements require fixed-rate interest payments averaging 0.71% for two-year periods commencing on various dates between January 2015 and April 2015.  Also during the current quarter, $1.10 billion notional amount of swaps requiring fixed-rate interest payments averaging 0.50% matured, while $500 million notional amount of forward-starting swaps requiring fixed-rate interest payments averaging 0.72% moved into current-pay status.

At March 31, 2015, the Company’s portfolio of financing-related swap positions had the following characteristics (dollars in thousands):

Period of Contract Expiration	Notional Amount		Average Fixed Rate Payment Requirement
Currently-paying contracts:
Second quarter 2015	$	200,000		0.43	%
Third quarter 2015		400,000		0.47

In addition to portfolio financing-related swap positions, in 2010 the Company entered into three forward-starting, three-month LIBOR-indexed, pay-fixed, receive-variable, interest rate swap agreements with notional amounts totaling $100 million and average fixed rates of 4.09% with 20-year payment terms coinciding with the floating-rate terms of the Company’s Unsecured borrowings which begin between October 30, 2015 and September 15, 2016.  These Derivatives are designated as cash flow hedges of the variability of the underlying benchmark interest rate associated with the floating-rate terms of these long-term borrowings (see NOTE 7).

-12-

Interest rate swap agreements are measured at fair value on a recurring basis primarily using Level Two Inputs in accordance with ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820).  In determining fair value estimates for these Derivatives, Capstead utilizes the standard methodology of netting the discounted future fixed cash payments and the discounted future variable cash receipts which are based on expected future interest rates derived from observable market interest rate curves.  Related net interest payable at the balance sheet date is recorded separately.  The Company also incorporates both its own nonperformance risk and its counterparties’ nonperformance risk in determining the fair value of these Derivatives.  In considering the effect of nonperformance risk, the Company considered the impact of netting and credit enhancements, such as collateral postings and guarantees, and has concluded that counterparty risk is not significant to the overall valuation of these agreements.

The following tables include fair value and other related disclosures regarding all Derivatives held as of and for the indicated periods (in thousands):

NOTE 7 ¾ UNSECURED BORROWINGS

Unsecured borrowings consist of 30-year junior subordinated notes issued in 2005 and 2006 and maturing in 2035 and 2036.  Included in Receivables and other assets are $2.1 million in remaining issue costs at March 31, 2015 associated with the original issuance of these notes.  Note balances and related weighted average interest rates as of March 31, 2015 and December 31, 2014 (calculated including issue cost amortization) were as follows (dollars in thousands):

	Borrowings Outstanding		Average Rate *
Junior subordinated notes maturing in:
October 2035	$	35,000		8.31	%
December 2035		40,000		8.46
September 2036		25,000		8.78
	$	100,000		8.49

* The indicated weighted average rates have been in effect since issuance.  After considering cash flow hedges that coincide with the floating rate terms of these borrowings that begin October 30, and December 15, 2015 for the notes maturing in October and December 2035 and September 15, 2016 for the notes maturing in September 2036, the effective borrowing rate will average 7.56% beginning September 15, 2016 through maturity, subject to certain adjustments for the effects of measured hedge ineffectiveness, if any.

The notes maturing in October 2035 are currently redeemable, in whole or in part, without penalty, at the Company’s option.  The notes maturing in December 2035 are redeemable, in whole or in part, without penalty, at the Company’s option anytime on or after December 15, 2015.  The notes maturing in September 2036 are redeemable, in whole or in part, without penalty, at the Company’s option anytime on or after September 15, 2016.

NOTE 8 ¾ CAPITAL TRANSACTIONS

During the quarter ended March 31, 2015, Capstead issued an additional 432,000 shares of its 7.50% Series E Cumulative Redeemable Preferred Stock through an at-the-market continuous offering program at an average price of $24.67, net of underwriting fees and other costs, for net proceeds of $10.7 million.  Amounts raised subsequent to quarter-end under this program have been minimal.

NOTE 9 ¾ DISCLOSURES REGARDING FAIR VALUES OF FINANCIAL INSTRUMENTS

This note provides fair value-related disclosures as of the indicated balance sheet dates for Capstead’s financial assets and liabilities, most of which are influenced by changes in, and market expectations for changes in, interest rates and market liquidity conditions, as well as other factors beyond the control of management.  All fair values were determined using Level 2 Inputs in accordance with ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820).

Residential mortgage investments, nearly all of which are mortgage securities classified as available-for-sale, are measured at fair value on a recurring basis.  In determining fair value estimates for mortgage securities, the Company considers recent trading activity for similar investments and pricing levels indicated by lenders in connection with designating collateral for repurchase arrangements, provided such pricing levels are considered indicative of actual market clearing transactions.  In determining fair value estimates for longer-term borrowings under repurchase arrangements, the Company considers pricing levels indicated by lenders for entering into new transactions using similar pledged collateral with terms equal to the remaining terms of the longer-term borrowings.  In determining fair value estimates for unsecured borrowings, the Company considers current pricing for financial instruments with similar characteristics.  Excluded from these disclosures are financial instruments for which the Company’s cost basis is deemed to approximate fair value due primarily to the short duration of these instruments, which are valued using primarily Level 1 measurements, including Cash and cash equivalents, cash collateral receivable from, or payable to, interest rate swap counterparties, receivables, payables and borrowings under repurchase arrangements with initial terms of 120 days or less.  See NOTE 6 for information relative to the valuation of interest rate swap agreements.

	$	937,977	$	4,462	$	1,802,563	$	7,375

Capstead’s investment strategy involves managing a leveraged portfolio of relatively short-duration ARM Agency Securities and management expects these securities will be held until payoff absent a major shift in strategy or a severe contraction in the Company’s ability to obtain financing to support its portfolio.  Declines in fair value caused by increases in interest rates are typically modest for investments in short-duration ARM Agency Securities compared to investments in longer-duration ARM or fixed-rate assets.  These declines are generally recoverable in a relatively short period of time as coupon interest rates on the underlying mortgage loans reset to rates more reflective of the then current interest rate environment.

From a credit risk perspective, federal government support for the GSEs helps ensure that fluctuations in value due to credit risk associated with these securities will be limited.  Given that (a) any existing unrealized losses on mortgage securities held by the Company are not attributable to credit risk and declines in fair value of ARM securities due to changes in interest rates are generally recoverable in a relatively short period of time, (b) the Company typically holds its investments to maturity, and (c) it is more likely than not that the Company will not be required to sell any of its investments given the resiliency of the financing market for Agency Securities, none of these investments are considered other-than-temporarily impaired at March 31, 2015.

NOTE 10 ¾ COMPENSATION PROGRAMS

The compensation committee of Capstead’s board of directors (the “Committee”) is responsible for establishing, implementing, and monitoring the Company’s compensation program and practices.  In 2013 the Committee replaced an absolute return-based, discretionary bonus program and an absolute return-based stock award program with largely nondiscretionary and formulaic, target-based annual and long-term incentive compensation programs for key executives with multiple, pre-established performance goals and defined threshold, target and maximum awards as a percentage of base salary.

-17-

Equity-based awards as well as other incentive awards that recognize the creation of value for stockholders and promote the Company’s long-term growth and success are made pursuant to the Company’s Amended and Restated 2014 Flexible Incentive Plan, approved by stockholders in May 2014.  At March 31, 2015, this plan had 4,432,739 shares of common stock remaining available for future issuances.

Short-term Incentive Compensation Programs

As more fully described in the Company’s proxy statement, the Committee periodically reviews Capstead’s annual incentive compensation program, establishing and implementing desired changes in performance metrics, composition of the mortgage REIT industry peer group used for measurement purposes and each participating officer’s targeted award opportunity.  Under the provisions of the program in effect for 2015 and 2014, awards are made based on (a) economic return (change in book value plus dividends) measured on a relative basis, and, to a lesser extent, on an absolute return basis, (b) relative operating cost efficiency (operating expenses divided by Unsecured borrowings and Stockholders’ equity), and (c) each participating officer’s attainment of stated goals and objectives.  Each participating officer has a targeted award opportunity equal to 125% of his base salary.  Under the terms of the program, each performance metric is assigned a weighting and the Company’s performance relative to each metric is calculated separately. No awards can be earned for performance below the defined threshold returns and awards are capped for performance above the defined maximum return levels.  Included in Accounts payable and accrued expenses at March 31, 2015 are annual incentive compensation accruals for all employees totaling $489,000.  Recognized in Short-term incentive compensation are $489,000 and $318,000 related to annual incentive compensation for all employees for the quarters ended March 31, 2015 and 2014, respectively.

The Committee administers an additional performance-based short-term incentive compensation program for key executives that provides for quarterly cash payments equal to per share dividends declared on Capstead’s common stock multiplied by a notional amount of non-vesting shares of common stock (“Dividend Equivalent Rights” or “DERs”).  DERs only represent the right to receive the same cash distributions that the Company’s common stockholders are entitled to receive during the term of the grants, subject to certain conditions, including continuous service.  In December 2014 the Committee extended the term of the 654,000 outstanding DERs to December 31, 2015.  Included in Accounts payable and accrued expenses are first quarter 2015 DERs distribution amounts totaling $203,000 that were paid in April 2015.  Recognized in Short-term incentive compensation are $203,000 and $222,000 related to the DERs program for the quarters ended March 31, 2015 and 2014, respectively.

Long-term Equity-based Awards – Performance-based RSUs

The Committee adopted a new performance-based long-term incentive compensation program for key executives in December 2013.  The program provides for the grant of performance-based RSUs that are convertible into common shares following three-year performance periods, contingent upon whether, and to what extent, defined performance levels established for certain relative and absolute return performance metrics are met or exceeded.  The relative return metrics measure the Company’s performance against its peers in the mortgage REIT industry on the basis of relative economic return and relative total stockholder return (change in stock price plus reinvested dividends).  The absolute economic return metric measures performance against defined return levels.  For conversion purposes, each performance metric is assigned a weighting and the Company’s performance relative to each metric is calculated separately.  The actual number of shares of common stock the units can convert into for each of the metrics, if any, can range from one-half of a share per unit if that metric’s minimum threshold of performance is met, to two shares per unit if the related maximum performance threshold is met or exceeded, adjusted for the weighting assigned to the metric.  If a metric’s minimum performance threshold is not met, no shares are issuable under that metric.  Dividends accrue from the date of grant and will be paid in cash when the units convert into shares of common stock based on the number of shares ultimately issued, if any.

-18-

Pursuant to this program, in January 2015 and December 2013 the Committee granted 247,512 and 242,505 RSUs with three-year performance periods ending December 31, 2017 and 2016, respectively.  Initial grant date fair values of $8.83 and $12.45 were assigned to each unit of the January 2015 and December 2013 grants, respectively.  In the fourth quarter of 2014 the three-year compensation cost estimate for the December 2013 grant was reduced to $7.21 per unit.  Recognized in Long-term incentive compensation are $328,000 and $251,000 related to the RSUs for the quarters ended March 31, 2015 and 2014, respectively.

Long-term Equity-based Awards – Stock Awards

Under an absolute return performance-based stock award program terminated in 2013, the Committee granted common stock awards to all employees with staggered three-year vesting periods.  These awards vest if annualized returns in excess of established return levels are generated during three-year measurement periods.  Vesting can be deferred and a new three-year measurement period established to include the subsequent year, up to and including the seventh calendar year after the year of grant.  Any remaining unvested awards issued under this program will expire if the required returns are not generated for the final three-year measurement period.  Grants made under this program totaling 125,221 shares with an average grant date fair value of $12.58 vested in February 2015 pertaining to initial measurement periods ending December 31, 2014.  Remaining grants under this program totaling 133,571 and 69,849 shares with average grant date fair values of $12.17 and $11.67 are scheduled to vest in February 2016 and 2017, respectively, assuming performance criteria and service conditions are met.

In December 2014 and 2013 respectively, the Committee granted service-based stock awards for 37,237 and 35,703 shares of common stock with grant date fair values of $12.47 and $12.34 to employees not awarded RSUs.  These awards vest January 2, 2018 and January 2, 2017, respectively, assuming service conditions are met.  In January 2014 the remaining 22,164 shares associated with 2007 service-based stock awards issued to all employees vested.  As a component of the Company’s director compensation program, directors are granted stock awards annually upon election or re-election to the board of directors that vest approximately one year from issuance.  In July 2014, director stock awards for 35,000 shares with a grant date fair value of $13.16 were granted that vest in July 2015, assuming service conditions are met.  In April 2014, director grants awarded in 2013 for 28,000 shares with a grant date fair value of $13.02 vested.

Performance-based and service-based stock award activity for quarter ended March 31, 2015 is summarized below:

	Number of Shares			Weighted Average Grant Date Fair Value
Unvested stock awards outstanding at December 31, 2014		436,581			12.29
Vestings		(125,221	)		12.58
Unvested stock awards outstanding at March 31, 2015		311,360			12.18

During the quarters ended March 31, 2015 and 2014, the Company recognized in Long-term incentive compensation $280,000 and $375,000, respectively, related to amortization of the grant date fair value of employee performance-based and service-based stock awards.  The amounts amortized for these periods assumed that performance metrics, if applicable, would continue to be met for related initial measurement periods.  In addition, the Company recognized in Other general and administrative expense $115,000 and $92,000 related to amortization of the grant date fair value of service-based director stock awards during the quarters ended March 31, 2015 and 2014, respectively.

-19-

All service-based stock awards receive dividends on a current basis without risk of forfeiture if the related awards do not vest.  Outstanding performance-based stock awards defer the payment of dividends accruing between the grant dates and the end of related performance periods.  If these awards do not vest, the related accrued dividends will be forfeited.

Long-term Equity-based Awards – Option Awards

Option awards currently outstanding have ten-year contractual terms from the grant date and were issued with strike prices equal to the quoted market prices of Capstead’s common shares on the dates of grant, all of which were prior to 2010.  No option award activity occurred during the quarter ended March 31, 2015.  All outstanding option awards are exercisable at March 31, 2015.  These awards totaled 40,000 shares with a weighted average remaining contractual term of 3.2 years and an aggregate intrinsic value of $13,000.  The fair value of these awards was estimated on the dates of grant using a Black-Scholes option pricing model and was expensed over the related vesting periods.

Other Benefit Programs

Capstead sponsors a qualified defined contribution retirement plan for all employees and a nonqualified deferred compensation plan for certain of its executives.  In general the Company matches up to 50% of a participant’s voluntary contribution up to a maximum of 6% of a participant’s base salary and annual incentive compensation payments and makes discretionary contributions of up to another 3% of such compensation regardless of participation in the plans.  Company contributions are subject to certain vesting requirements that have been met by nearly all of Capstead’s current employees.  During the quarters ended March 31, 2015 and 2014, the Company recognized in Salaries and benefits $75,000 and $64,000 related to contributions to these plans, respectively.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

FINANCIAL CONDITION

Overview

Capstead operates as a self-managed REIT and earns income from investing in a leveraged portfolio of residential mortgage pass-through securities consisting almost exclusively of short-duration ARM Agency Securities, which are considered to have limited, if any, credit risk and reset to more current interest rates within a relatively short period of time.  See NOTE 1 to the consolidated financial statements (included under Item 1 of this report) for certain defined terms used in this discussion and analysis.  Capstead’s strategy of investing in ARM Agency Securities positions the Company to benefit from potential recoveries in financing spreads that typically contract during periods of rising interest rates and experience smaller fluctuations in portfolio values compared to leveraged portfolios containing a significant amount of longer-duration ARM or fixed-rate mortgage securities.  Duration is a common measure of market price sensitivity to interest rate movements.  A shorter duration generally indicates less interest rate risk.

Capstead finances its residential mortgage investments with borrowings under repurchase arrangements with commercial banks and other financial institutions (referred to as “repo” borrowings) supported by its long-term investment capital.  As of March 31, 2015, long-term investment capital totaled $1.50 billion and consisted of $1.20 billion of common and $195 million of perpetual preferred stockholders’ equity (recorded amounts) and $100 million of unsecured borrowings that mature in 2035 and 2036.  Long-term investment capital increased by $6 million during the quarter ended March 31, 2015 primarily as a result of raising $11 million in new 7.50% Series E preferred capital using an at-the-market continuous offering program and higher portfolio pricing levels, partially offset by lower pricing levels for interest rate swap agreements held for hedging purposes.

Capstead’s holdings of residential mortgage investments increased by $242 million during the quarter to $14.15 billion at March 31, 2015, with portfolio acquisitions exceeding portfolio runoff by $227 million (principal amount).  Repo borrowings increased by $132 million during the quarter to $12.94 billion at March 31, 2015.  Portfolio leverage (repo borrowings divided by long-term investment capital) increased to 8.65 to one at March 31, 2015 from 8.59 to one at December 31, 2014.  Management believes borrowing at current levels represents an appropriate and prudent use of leverage for a portfolio consisting of seasoned, short-duration ARM Agency Securities.

Capstead reported net income of $34 million or $0.32 per diluted common share for the first quarter of 2015 compared to $33 million or $0.31 per diluted common share for the fourth quarter of 2014 and $38 million or $0.37 per diluted common share for the first quarter of 2014.  The Company declared a first quarter 2015 common dividend of $0.31 per share that was paid April 20, 2015 to holders of record on March 31, 2015.

Financing spreads on residential mortgage investments averaged 1.11% for the first quarter of 2015, compared to 1.10% for the fourth quarter of 2014 and 1.30% for the first quarter of 2014.  Financing spreads on residential mortgage investments is a non-GAAP financial measure based solely on yields on residential mortgage investments, net of repo borrowing rates, adjusted for currently-paying interest rate swap agreements held for hedging purposes.  This measure differs from total financing spreads, an all-inclusive GAAP measure that includes yields on all interest-earning assets, as well as rates paid on all interest-bearing liabilities, principally unsecured borrowings.  See page 28 for a reconciliation of these GAAP and non-GAAP financial measures.

Risk Factors and Critical Accounting Policies

Under the captions “Risk Factors” and “Critical Accounting Policies” are discussions of risk factors and critical accounting policies affecting Capstead’s financial condition and earnings that are an integral part of this discussion and analysis.  Readers are strongly urged to consider the potential impact of these factors and accounting policies on the Company and its financial results.

Capital Transactions

During the quarter ended March 31, 2015, Capstead issued an additional 432,000 shares of its 7.50% Series E Cumulative Redeemable Preferred Stock through an at-the-market continuous offering program at an average price of $24.67, net of underwriting fees and other costs, for net proceeds of $11 million.  Amounts raised subsequent to quarter-end under this program have been minimal.

Additional amounts of Series E preferred capital and new common equity capital may be raised in the future under continuous offering programs or by other means, subject to market conditions, compliance with federal securities laws and blackout periods associated with the dissemination of earnings and dividend announcements and other important Company-specific news.

Book Value per Common Share

Nearly all of Capstead’s residential mortgage investments and all of its interest rate swap agreements are reflected at fair value on the Company’s balance sheet and are therefore included in the calculation of book value per common share (total stockholders’ equity, less liquidation preferences for outstanding shares of preferred stock, divided by outstanding shares of common stock).  Fair value is impacted by market conditions, including changes in interest rates, and the availability of financing at reasonable rates and leverage levels, among other factors.

Capstead’s investment strategy attempts to mitigate these risks by focusing on investments in Agency Securities, which are considered to have little, if any, credit risk and are collateralized by ARM loans with interest rates that reset periodically to more current levels generally within five years.  Because of these characteristics, the fair value of the Company’s portfolio is considerably less vulnerable to significant pricing declines caused by credit concerns or rising interest rates compared to leveraged portfolios containing a significant amount of non-agency securities or longer-duration ARM and/or fixed-rate Agency Securities.

The following table illustrates the progression of Capstead’s book value per common share as well as changes in book value expressed as percentages of beginning book value for the quarter ended March 31, 2015:

Book value per common share, beginning of year	$	12.52

Residential Mortgage Investments

Capstead’s investment strategy focuses on managing a large portfolio of residential mortgage investments consisting almost exclusively of ARM Agency Securities.  Agency Securities are considered to have limited, if any, credit risk because the timely payment of principal and interest is guaranteed by the GSEs, which are federally chartered corporations, or Ginnie Mae, which is an agency of the federal government.  Federal government support for the GSEs has largely alleviated market concerns regarding the ability of the GSEs to fulfill their guarantee obligations.

ARM securities are 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, the coupon interest rates of mortgage loans underlying the Company’s ARM securities typically adjust either:

· 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”),

· semiannually based on specified margins over six-month LIBOR, or

· 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.

These coupon interest rate adjustments are 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.

By focusing on investing in short-duration ARM Agency Securities, changes in fair value caused by changes in interest rates are typically relatively modest compared to changes in fair value of investments in longer-duration ARM or fixed-rate assets.  Declines in fair value caused by increases in interest rates are generally recoverable in a relatively short period of time as coupon interest rates on the underlying mortgage loans reset to rates more reflective of the then current interest rate environment.  This investment strategy positions the Company to benefit from potential recoveries in financing spreads that typically contract during periods of rising interest rates.

The following table illustrates the progression of Capstead’s portfolio of residential mortgage investments for the quarter ended March 31, 2015 (dollars in thousands):

Residential mortgage investments, beginning of year	$	13,908,104
Increase in net unrealized gains on securities classified as available-for-sale		6,107
Portfolio acquisitions (principal amount) at average lifetime purchased yields of 2.36%		926,038
Investment premiums on acquisitions*		33,510
Portfolio runoff (principal amount)		(698,597	)
Investment premium amortization		(25,078	)
Residential mortgage investments, end of quarter	$	14,150,084
Increase in residential mortgage investments outstanding during the quarter ended March 31, 2015	$	241,980

* Residential mortgage investments typically are acquired at a premium to the securities’ unpaid principal balances.  Investment premiums are recognized in earnings as portfolio yield adjustments using the interest method over the estimated lives of the related investments.  As such, the level of mortgage prepayments impacts how quickly investment premiums are amortized.

-23-

Capstead classifies its ARM securities based on the average length of time until the loans underlying each security reset to more current rates (“months-to-roll”) (less than 18 months for “current-reset” ARM securities, and 18 months or greater for “longer-to-reset” ARM securities).  After consideration of any applicable initial fixed-rate periods, at March 31, 2015 approximately 86%, 9% and 5% of the Company’s ARM securities were backed by mortgage loans that reset annually, semi-annually and monthly, respectively.  Approximately 77% of the Company’s current-reset ARM securities have reached an initial coupon reset date, while none of its longer-to-reset ARM securities have reached an initial coupon reset date.  Additionally, at March 31, 2015 approximately 11% of the Company’s ARM securities were backed by interest-only loans, with remaining interest-only payment periods of up to nine years.  All percentages are based on averages of the characteristics of mortgage loans underlying each security and calculated using unpaid principal balances as of the indicated date.

Capstead’s ARM holdings featured the following characteristics at March 15, 2015 (dollars in thousands):

ARM Type	Amortized Cost Basis (a)		Net WAC(b)			Fully Indexed WAC(b)			Average Net Margins (b)			Average Periodic Caps(b)			Average Lifetime Caps(b)			Months To Roll
Current-reset ARMs:
Fannie Mae Agency Securities	$	4,453,534		2.29	%		2.14	%		1.71	%		3.34	%		9.84	%		5.6
Freddie Mac Agency Securities		1,723,854		2.42			2.24			1.82			2.53			10.11			6.9
Ginnie Mae Agency Securities		1,671,057		2.40			1.62			1.51			1.06			8.46			7.4
Residential mortgage loans		2,903		3.39			2.23			2.04			1.59			10.98			4.8

	$	13,886,212		2.53			2.07			1.67			2.89			8.84			20.8
Gross WAC (rate paid by borrowers) (c)				3.14

(a) Amortized cost basis represents the Company’s investment (unpaid principal balance plus unamortized investment premiums) before unrealized gains and losses.  At March 31, 2015, the ratio of amortized cost basis to unpaid principal balance for the Company’s ARM holdings was 103.28.  This table excludes $5 million in fixed-rate Agency Securities, residential mortgage loans and private residential mortgage pass-through securities held as collateral for structured financings.

(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 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.  Fully indexed WAC represents the weighted average coupon upon one or more resets using interest rate indexes and net margins as of the indicated date.  Average net margins represent the weighted average levels over the underlying indexes that the portfolio can adjust to upon reset, usually subject to initial, periodic and/or lifetime caps on the amount of such adjustments during any single interest rate adjustment period and over the contractual term of the underlying loans.  ARM securities issued by the GSEs with initial fixed-rate periods of five years or longer typically have either 200 or 500 basis point initial caps with 200 basis point periodic caps.  Additionally, certain ARM securities held by the Company are subject only to lifetime caps or are not subject to a cap.  For presentation purposes, average periodic caps in the table above reflect initial caps until after an ARM security has reached its initial reset date and lifetime caps, less the current net WAC, for ARM securities subject only to lifetime caps.  At quarter-end, 66% of current-reset ARMs were subject to periodic caps averaging 1.79%; 23% were subject to initial caps averaging 3.09%; 10% were subject to lifetime caps averaging 7.68%; and 1% were not subject to a cap.  All longer-to-reset ARM securities at March 31, 2015 were subject to initial caps.

(c) Gross WAC is the weighted average interest rate of the mortgage loans underlying the indicated investments, including servicing and other fees paid by borrowers, as of the indicated balance sheet date.

Capstead pledges its residential mortgage investments as collateral under repurchase arrangements with commercial banks and other financial institutions, referred to as counterparties, the terms and conditions of which are negotiated on a transaction-by-transaction basis when each such repo borrowing is initiated or renewed.  None of the Company’s counterparties are obligated to renew or otherwise enter into new repurchase transactions at the conclusion of existing repurchase transactions.  Repurchase arrangements entered into by the Company involve the sale and a simultaneous agreement to repurchase the transferred assets at a future date, routinely with terms of 30 to 90 days, and are accounted for as borrowings by the Company.  The Company maintains the beneficial interest in the specific securities pledged during each borrowing’s term and receives the related principal and interest payments.  The amount borrowed is generally equal to the fair value of the securities pledged, as determined by the lending counterparty, less an agreed-upon discount, referred to as a “haircut.”  Haircuts on outstanding repo borrowings averaged 4.5 percent and ranged from 3.0 to 5.0 percent of the fair value of pledged residential mortgage pass-through securities at March 31, 2015, little changed from the prior year.  After considering haircuts and related interest receivable on the collateral, as well as interest payable on these borrowings, the Company had $677 million of capital at risk with its lending counterparties at March 31, 2015.  The Company did not have capital at risk with any single counterparty exceeding 4.0% at March 31, 2015.

-24-

Repo borrowing rates are fixed based on prevailing rates corresponding to the terms of the borrowings, and interest is paid at the termination of a repurchase arrangement at which time the Company may enter into a new repurchase arrangement at prevailing haircuts and rates with the same counterparty or repay that counterparty and negotiate financing with a different counterparty.  When the fair value of pledged securities declines due to changes in market conditions or the publishing of monthly security pay down factors, lenders typically require the Company to post additional securities as collateral, pay down borrowings or fund cash margin accounts with the counterparties in order to re-establish the agreed-upon collateral requirements, referred to as margin calls.  Conversely, if collateral fair values increase, lenders are required to release collateral back to the Company pursuant to Company-issued margin calls.

As of March 31, 2015 the Company’s repo borrowings totaled $12.94 billion with 25 counterparties at average rates of 0.39%, before the effects of interest rate swap agreements held as cash flow hedges and 0.59% including the effects of these derivatives.  To help mitigate exposure to higher short-term interest rates and to secure longer-term, committed financing, Capstead may enter into longer-maturity repurchase arrangements if available at attractive rates and terms.  To this end, during the first quarter of 2015 the Company entered into $600 million in 18- to 24-month repo borrowings with average initial maturities of 19 months and borrowing rates of 0.79%, bringing total repo borrowings with initial maturities of at least 12 months to $2.38 billion with average remaining maturities of 11 months and average borrowing rates of 0.61%.

To further reduce exposure to higher short-term interest rates, the Company uses currently-paying and forward-starting, one-month LIBOR-indexed, pay-fixed, receive-variable, interest rate swap agreements that require interest payments for two-year terms.  Variable payments received by the Company under these swap agreements offset a significant portion of the interest accruing on a like amount of the Company’s 30- to 90-day repo borrowings.  As a result, the Company’s effective borrowing rate for these borrowings consists of fixed-rate payments made on the swap agreements adjusted for differences between variable rate payments received on the swap agreements and related actual repo borrowing rates, as well as the effects of measured hedge ineffectiveness.

At March 31, 2015 the Company held portfolio financing-related swap agreements totaling $7.30 billion notional amount with average contract expirations of 12 months.  These swap positions consisted of (a) $7.10 billion notional amount in currently-paying swap agreements requiring the payment of fixed rates of interest averaging 0.54% for average remaining interest-payment terms of 12 months and (b) $200 million notional amount in forward-starting swap agreements that will begin requiring fixed rate interest payments averaging 0.72% for two-year periods commencing in April 2015, with average contract expirations of 24 months.

After consideration of all portfolio financing-related swap positions entered into as of quarter-end, the Company’s residential mortgage investments and related repo borrowings had estimated durations at March 31, 2015 of 11 and 9 months, respectively, for a net duration gap of approximately 2 months – see pages 32 and 33 under the caption “Interest Rate Risk” for further information about the Company’s sensitivity to changes in market interest rates.  The Company intends to continue to manage interest rate risk associated with holding and financing is residential mortgage investments by utilizing suitable derivative financial instruments such as interest rate swap agreements as well as longer-maturity repo borrowings if available at attractive terms.

Analysis of Quarterly Financing Spreads

Components of quarterly financing spreads on residential mortgage investments, a non-GAAP financial measure, and mortgage prepayment rates, were as follows for the indicated periods:

	2015			2014									2013
		Q1			Q4		Q3		Q2		Q1			Q4		Q3		Q2
Yields on residential mortgage investments:(a)
Cash yields		2.42	%		2.43	%	2.44	%	2.46	%	2.46	%		2.48	%	2.50	%	2.52	%
Investment premium amortization		(0.72	)		(0.77	)	(0.84	)	(0.75	)	(0.67	)		(0.74	)	(1.14	)	(0.99	)
Adjusted yields		1.70			1.66		1.60		1.71		1.79			1.74		1.36		1.53
Related borrowing rates:(b)
Repo borrowing rates		0.38			0.36		0.32		0.32		0.34			0.38		0.37		0.39
Fixed swap rates		0.53			0.51		0.50		0.49		0.50			0.52		0.59		0.65
Adjusted borrowing rates		0.59			0.56		0.51		0.49		0.49			0.49		0.49		0.53
Financing spreads on residential mortgage investments(c)		1.11			1.10		1.09		1.22		1.30			1.25		0.87		1.00
CPR		16.66			17.58		19.18		17.22		15.16			17.14		25.49		23.12

(a) Cash yields are based on the cash component of interest income.  Investment premium amortization is determined using the interest method which incorporates actual and anticipated future mortgage prepayments.  Both are expressed as a percentage calculated on an annualized basis on average amortized cost basis for the indicated periods.

(b) Repo borrowing rates represent average rates on repurchase agreements and similar borrowings, before consideration of related currently-paying interest rate swap agreements.

Fixed swap rates represent the average fixed-rate payments made on currently-paying interest rate swap agreements held for portfolio hedging purposes and exclude effects of the spread between LIBOR-based variable-rate payments received on these swaps and designated 30- to 90-day repo borrowing rates, as well as the effects of any hedge ineffectiveness.  These effects averaged 22 basis points on average currently-paying swap notional amounts outstanding during the first quarter of 2015, 18 basis points during 2014 and 19 basis points during 2013.

Adjusted borrowing rates reflect repo borrowing rates, fixed swap rates and the above-mentioned differences. All rates presented are expressed as a percentage calculated on an annualized basis for the indicated periods.

(c) See page 28 for the Company’s rationale for using this non-GAAP financial measure and a reconciliation to its related GAAP financial measure, total financing spreads.

During the first quarter of 2015, cash yields continued a trend of gradual quarterly declines in large part due to coupon interest rates on more of the loans underlying the portfolio reset to fully-indexed levels in the current low interest rate environment.  With the underlying indexes (principally one-year LIBOR) beginning to increase in anticipation of Federal Reserve action to increase short-term interest rates, cash yields may have an opportunity to begin trending higher in future quarters.

Portfolio yield adjustments for investment premium amortization are primarily driven by changes in mortgage prepayment rates and investment premium levels.  Quarterly mortgage prepayment levels are influenced by the availability of mortgage financing at attractive terms and the health of the housing markets, as well as routine seasonal factors.  Mortgage prepayments declined during the first quarter of 2015 primarily due to seasonal factors, leading to lower investment premium amortization and higher yields.  Mortgage prepayments increased for the month of April such that second quarter portfolio yields are expected to be negatively impacted.

Adjusted for portfolio financing-related and currently-paying interest rate swap agreements, borrowing rates averaged 0.59% during the first quarter of 2015, an increase of three basis points from the fourth quarter of 2014 primarily reflecting a greater use of longer-maturity repo borrowings and higher interest rate swap costs.  Future borrowing rates will be dependent on market conditions, including the availability of longer-maturity repo borrowings and interest rate swap agreements at attractive rates.  See NOTE 6 to the consolidated financial statements for further information regarding the Company’s currently-paying and forward-starting swap agreements.

Utilization of Long-term Investment Capital and Potential Liquidity

Capstead’s investment strategy involves managing an appropriately leveraged portfolio of ARM Agency Securities that management believes can produce attractive risk-adjusted returns over the long term, while reducing, but not eliminating, sensitivity to changes in interest rates.  Repo borrowings generally can be increased or decreased on a daily basis to meet cash flow requirements and otherwise manage capital resources efficiently.  Consequently, potential liquidity inherent in the Company’s unencumbered residential mortgage investments is as important as the actual level of cash and cash equivalents carried on the balance sheet.  Potential liquidity is affected by, among other things:

· current portfolio leverage levels,

· changes in market value of assets pledged and interest rate swap agreements held for hedging purposes as determined by lending and swap counterparties,

· principal prepayments,

· collateral requirements of lenders and swap counterparties, and

· general conditions in the commercial banking and mortgage finance industries.

Future levels of portfolio leverage will be dependent upon many factors, including the size and composition of the Company’s investment portfolio (see “Liquidity and Capital Resources”).

Capstead’s utilization of its long-term investment capital and its estimated potential liquidity were as follows as of March 31, 2015 in comparison with December 31, 2014 (in thousands):

	Investments (a)		Repo Borrowings		Capital Employed		Potential Liquidity(b)		Portfolio Leverage
Balances as of March 31, 2015:
Residential mortgage investments	$	14,150,084	$	12,938,508	$	1,211,576	$	543,830
Cash collateral receivable from swap counterparties, net (c)						24,163		–
Other assets, net of other liabilities						260,560		205,615
					$	1,496,299	$	749,445	8.65:1
Balances as of December 31, 2014	$	13,908,104	$	12,806,843	$	1,490,771	$	753,575	8.59:1

(a) Investments are stated at balance sheet carrying amounts, which generally reflect estimated fair value as of the indicated dates.

(b) Potential liquidity is based on maximum amounts of borrowings available under existing uncommitted repurchase arrangements considering management’s estimate of the fair value of related collateral as of the indicated dates adjusted for other sources of liquidity such as cash and cash equivalents.

(c) Cash collateral receivable from swap counterparties is presented net of cash collateral payable to swap counterparties, if applicable, and the fair value of interest rate swap positions as of the indicated date.

In order to prudently and efficiently manage its liquidity and capital resources, Capstead attempts to maintain sufficient liquidity reserves to fund borrowing and interest rate swap margin calls under stressed market conditions, including margin calls resulting from monthly principal payments (remitted to the Company 20 to 45 days after any given month-end), as well as reasonably possible declines in the market value of pledged assets and swap positions.  Should market conditions deteriorate, management may reduce portfolio leverage and increase liquidity by raising new equity capital, selling mortgage securities and/or curtailing the replacement of portfolio runoff.  Additionally, the Company routinely does business with a large number of lending counterparties, which bolsters financial flexibility to address challenging market conditions and limits exposure to any individual counterparty.

-27-

At March 31, 2015 portfolio leverage increased marginally from year-end, reflecting modest increases in the size of the portfolio and in long-term investment capital.  Management believes current portfolio leverage levels represent an appropriate and prudent use of leverage under current market conditions for a portfolio consisting of seasoned, short-duration ARM Agency Securities.

Reconciliation of GAAP and non-GAAP Financing Spread Disclosures

Financing spreads on residential mortgage investments differs from total financing spreads, an all-inclusive GAAP measure, that is based on all interest-earning assets and liabilities.  Management believes presenting financing spreads on residential mortgage investments provides useful information for evaluating portfolio performance.  The following reconciles these measures for the indicated periods:

	2015			2014									2013
		Q1			Q4		Q3		Q2		Q1			Q4		Q3		Q2
Financing spreads on residential mortgage investments		1.11	%		1.10	%	1.09	%	1.22	%	1.30	%		1.25	%	0.87	%	1.00	%
Impact of lower yields on other interest-earning assets*		(0.04	)		(0.05	)	(0.04	)	(0.05	)	(0.04	)		(0.03	)	(0.02	)	(0.05	)
Impact of higher borrowing rates on other interest-paying liabilities*		(0.06	)		(0.07	)	(0.06	)	(0.07	)	(0.07	)		(0.07	)	(0.06	)	(0.06	)
Total financing spreads		1.01			0.98		0.99		1.10		1.19			1.15		0.79		0.89

* Other interest-earning assets consist of overnight investments and cash collateral receivable from interest rate swap counterparties. Other interest-paying liabilities consist of $100 million in unsecured borrowings (at an average borrowing rate of 8.49%) that the Company considers a component of its long-term investment capital and, where applicable, cash collateral payable to interest rate swap counterparties.

Capstead net income totaled $34 million or $0.32 per diluted common share for the first quarter of 2015 compared to $38 million or $0.37 per diluted common share for the first quarter of 2014.  The benefit to net interest margins of a 4.4% increase in average portfolio outstanding was offset by lower cash yields and higher investment premium amortization as well as higher borrowing rates.

Financing spreads on residential mortgage investments averaged 1.11% for the first quarter of 2015, compared to 1.30% for the first quarter of 2014.  Financing spreads on residential mortgage investments is a non-GAAP financial measure based solely on yields on residential mortgage investments, net of repo borrowing rates, adjusted for currently-paying interest rate swap agreements held for hedging purposes.  This measure differs from total financing spreads, an all-inclusive GAAP measure that includes yields on all interest-earning assets, as well as rates paid on all interest-bearing liabilities, principally unsecured borrowings.  See page 28 for a reconciliation of these GAAP and non-GAAP financial measures.

Yields on residential mortgage investments averaged 1.70% during the quarter ended March 31, 2015, compared to 1.79% for the same period in 2014.  Cash yields averaged 2.42% during the quarter ended March 31, 2015, four basis points lower than in 2014 reflecting the effects of ARM loan coupon interest rates resetting lower to more current rates as well as lower coupon interest rates on acquisitions.  The rate of decline in cash yields has slowed over the last two years reflecting more loans underlying the portfolio resetting to fully-indexed levels.  The yield adjustment for investment premium amortization averaged 72 basis points during the first quarter of 2015, an increase of five basis points over the same period in 2014, reflecting an increase in investment premium amortization primarily resulting from a 10% increase in mortgage prepayment rates.

Repo borrowing rates, adjusted for currently-paying interest rate swap agreements held for hedging purposes, increased by ten basis points, averaging 0.59% during the quarter ended March 31, 2015.  Unadjusted repo borrowing rates accounted for four of the ten basis point increase with the remainder attributable to higher interest rate swap costs.  Higher unadjusted repo borrowing rates reflect the Company taking advantage of healthy repo market conditions by securing $2.38 billion in 12- to 24-month repo borrowings at average rates of 0.61%.  Swap costs were higher primarily because of higher fixed swap rates with the expiration of older, lower-rate swaps and higher currently-paying swap balances (currently-paying swap balances averaged $7.27 billion for the first quarter of 2015, compared to $5.69 billion for same period in 2014).  Note also that fixed swap rates exclude differences between LIBOR-based variable-rate payments received on these swaps and designated 30- to 90-day repo borrowing rates, as well as the effects of hedge ineffectiveness.  These differences averaged 22 basis points on average currently-paying swap notional amounts outstanding during the first quarter of 2015, compared to 18 basis points during the same period in 2014.  Future repo borrowing rates will be dependent on market conditions, including overall levels of market interest rates as well as the availability of longer-maturity repo borrowings and interest rate swap agreements at attractive rates.

Operating costs as a percentage of long-term investment capital averaged 0.94% for the first quarter of 2015, two basis points lower than reported for the same period in 2014, reflecting a modest increase in average long-term investment capital.  Higher short-term incentive compensation accruals were offset by lower general and administrative and benefit costs compared to the prior year.  See NOTE 10 to the accompanying consolidated financial statements (included in Item 1 of this report) for additional information regarding the Company’s compensation programs.

LIQUIDITY AND CAPITAL RESOURCES

Capstead’s primary sources of funds are repo borrowings and monthly principal and interest payments on its investments.  Other sources of funds may include proceeds from debt and equity offerings and asset sales.  The Company generally uses its liquidity to pay down repo borrowings to reduce borrowing costs and otherwise efficiently manage its long-term investment capital.  Because the level of these borrowings can generally be adjusted on a daily basis, the Company’s potential liquidity inherent in its unencumbered residential mortgage investments is as important as the level of cash and cash equivalents carried on the balance sheet.  The table included under “Utilization of Long-term Investment Capital and Potential Liquidity” on page 27 illustrates management’s estimate of additional funds potentially available to the Company as of March 31, 2015 and the accompanying discussion provides insight into the Company’s perspective on the appropriate level of portfolio leverage to employ under current market conditions.  The Company currently believes that it has sufficient liquidity and capital resources available for the acquisition of additional investments, repayments on borrowings and the payment of cash dividends as required for the Company’s continued qualification as a REIT.

Capstead pledges its residential mortgage investments as collateral under repurchase arrangements, the terms and conditions of which are negotiated on a transaction-by-transaction basis with commercial banks and other financial institutions, referred to as counterparties, when each such repo borrowing is initiated or renewed.  None of the Company’s counterparties are obligated to renew or otherwise enter into new repurchase transactions at the conclusion of existing repurchase transactions.  As of March 31, 2015, the Company had uncommitted repurchase facilities with a variety of lending counterparties to finance its portfolio, subject to certain conditions, and had borrowings outstanding with 25 of these counterparties.  Amounts available to be borrowed under these arrangements are dependent upon the willingness of lenders to participate in the financing of Agency Securities, lender collateral requirements and the lenders’ determination of the fair value of the securities pledged as collateral, which fluctuates with changes in interest rates and liquidity conditions within the commercial banking and mortgage finance industries.  Repo borrowings totaled $12.94 billion at March 31, 2015, with $10.56 billion maturing within 90 days.  Repo borrowings began the year at $12.81 billion and averaged $12.99 billion during the quarter.  Average repo borrowings during the year can differ from year-end balances for a number of reasons including portfolio growth or contraction as well as differences in the timing of portfolio acquisitions relative to portfolio runoff.

To help mitigate exposure to higher short-term interest rates and to secure longer-term, committed financing, Capstead may enter into longer-maturity repurchase arrangements if available at attractive rates and terms.  To this end, during the latter half of 2014 the Company entered into $1.78 billion in 12- to 18-month repo borrowings and during the first quarter of 2015 entered into an additional $600 million of 18- to 24-month repo borrowings bringing total repo borrowings with initial maturities of at least 12 months to $2.38 billion with average remaining maturities of 11 months.  To further reduce exposure to higher short-term interest rates, the Company uses currently-paying and forward-starting, one-month LIBOR-indexed, pay-fixed, receive-variable, interest rate swap agreements that require interest payments for two-year terms.  These derivative financial instruments are designated as cash flow hedges of a like amount of repo borrowings.  At March 31, 2015, portfolio financing-related swap agreements totaling $7.30 billion notional amount with average contract expirations of 12 months, consisting of (a) $7.10 billion notional amount in currently-paying swap agreements requiring the payment of fixed rates of interest averaging 0.54% for average remaining interest-payment terms of 12 months and (b) $200 million notional amount in forward-starting swap agreements that will begin requiring fixed rate interest payments averaging 0.72% for two-year periods commencing in April 2015, with average contract expirations of 24 months.

-31-

Relative to the floating rate terms of the Company’s $100 million in unsecured borrowings that begin at various dates between October 2015 and September 2016, the Company entered into forward-starting swap agreements to effectively lock in fixed rates of interest that will average 7.56% beginning in September 2016 through maturity in 2035 and 2036.  The Company intends to continue to utilize suitable derivative financial instruments such as interest rate swap agreements to manage interest rate risk.

During the first quarter of 2015, the Company raised $11 million in new preferred equity capital using an at-the-market continuous offering program established to issue additional shares of common stock and 7.50% Series E Cumulative Redeemable Preferred Stock.

Additional amounts of Series E preferred capital and new common equity capital may be raised in the future under continuous offering programs or by other means, subject to market conditions, compliance with federal securities laws and blackout periods associated with the dissemination of earnings and dividend announcements and other important Company-specific news.

Interest Rate Risk

Because Capstead’s residential mortgage investments consist almost entirely of Agency Securities, which are considered to have limited, if any, credit risk, interest rate risk is the primary market risk faced by the Company.  Interest rate risk is highly sensitive to a number of factors, including economic conditions, government fiscal policy, central bank monetary policy and banking regulation.  By focusing on investing in relatively short-duration ARM Agency Securities, declines in fair value caused by increases in interest rates are typically relatively modest compared to investments in longer-duration ARM or fixed-rate assets.  These declines can be recovered in a relatively short period of time as coupon interest rates on the underlying mortgage loans reset to rates more reflective of the then current interest rate environment.  This strategy also positions the Company to benefit from potential recoveries in financing spreads that typically contract during periods of rising interest rates.

To further reduce exposure to higher short-term interest rates, the Company uses longer-dated repo borrowings, if available at attractive rates and terms, as well as currently-paying and forward-starting interest rate swap agreements that typically require interest payments for two-year terms.  These transactions lengthen the effective duration of the Company’s borrowings to more closely match the duration of its investments.  After consideration of all swap positions entered into as of year-end to hedge changes in short-term interest rates, the Company’s residential mortgage investments and related repo borrowings had estimated durations at March 31, 2015 of 11 and 9 months, respectively, for a net duration gap of approximately 2 months.  The Company intends to continue to manage interest rate risk associated with holding and financing its residential mortgage investments by utilizing suitable derivative financial instruments such as interest rate swap agreements as well as longer-dated repo borrowings if available at attractive terms.

Capstead performs sensitivity analyses using a model to estimate the effects that specific interest rate changes can reasonably be expected to have on net interest margins and portfolio values.  All investments, related repo borrowings and derivative financial instruments held are included in these analyses.  For net interest margin modeling purposes, the model incorporates management’s assumptions for mortgage prepayment levels for a given interest rate change using market-based estimates of prepayment speeds for the purpose of amortizing investment premiums and reinvesting portfolio runoff.  These assumptions are developed through a combination of historical analysis and expectations for future pricing behavior under normal market conditions unaffected by changes in market liquidity.  For portfolio valuation modeling purposes, a static portfolio is assumed.

-32-

This modeling is the primary tool used by management to assess the direction and magnitude of changes in net interest margins and portfolio values resulting solely from changes in interest rates.  Key modeling assumptions include mortgage prepayment speeds, adequate levels of market liquidity, current market conditions, and portfolio leverage levels.  Given the present low level of interest rates, a floor of 0.00% is assumed.  However, it is assumed that borrowing rates cannot decline beyond a certain level.  These assumptions are inherently uncertain and, as a result, modeling cannot precisely estimate the impact of higher or lower interest rates.  Actual results will differ from simulated results due to the timing, magnitude and frequency of interest rate changes, other changes in market conditions, changes in management strategies and other factors.

The table below reflects the estimated impact of instantaneous parallel shifts in the yield curve on net interest margins and the fair value of Capstead’s portfolio of residential mortgage investments and related repo borrowings and derivative financial instruments as of the indicated dates, subject to the modeling parameters described above.

	Federal Funds Rate	10-year U.S. Treasury Rate			Down 0.50%			Up 0.50%			Up 1.00%
Projected 12-month percentage change in net interest margins: *
March 31, 2015	<0.25%		1.92	%		(18.3	)%		5.6	%		7.0	%
December 31, 2014	<0.25		2.17			(21.5	)		7.1			9.5
Projected percentage change in portfolio and related derivative values: *
March 31, 2015	<0.25		1.92			0.1			(0.2	)		(0.3	)
December 31, 2014	<0.25		2.17			0.1			(0.2	)		(0.3	)

  * Sensitivity of net interest margins as well as portfolio and related repo borrowings and derivative values to changes in interest rates is determined relative to the actual rates at the applicable date.  Note that the projected 12-month net interest margin change is predicated on acquisitions of similar assets sufficient to replace runoff.  There can be no assurance that suitable investments will be available for purchase at attractive prices, if investments made will behave in the same fashion as assets currently held or if management will choose to replace runoff with such assets.

RISK FACTORS

An investment in securities issued by Capstead involves various risks. An investor should carefully consider the following risk factors in conjunction with the other information contained in this document before purchasing the Company’s securities.  The risks discussed herein can adversely affect the Company’s business, liquidity, operating results, financial condition and future prospects, causing the market price of the Company’s securities to decline, which could cause an investor to lose all or part of his/her investment.  The risk factors described below are not the only risks that may affect the Company. Additional risks and uncertainties not presently known to the Company also may adversely affect its business, liquidity, operating results, prospects and financial condition.

Risks Related to Capstead’s Business

An increase in prepayments may adversely affect Capstead’s liquidity, financial condition and earnings. When short- and long-term interest rates are at nearly the same levels (i.e., a “flat yield curve” environment), or when long-term interest rates decrease, the rate of principal prepayments on mortgage loans underlying mortgage securities generally increases due to the availability of lower mortgage interest rates to homeowners.  Mortgage interest rates and the general availability of mortgage credit can also be impacted by regulatory changes in Agency guarantee fees, loan level pricing adjustments, down payment requirements, as well as other underwriting requirements.  Prolonged periods of high mortgage prepayments can significantly reduce the expected life of the Company’s portfolio of residential mortgage investments; therefore, actual yields the Company realizes can be lower due to faster amortization of investment premiums, which could adversely affect earnings.  High levels of mortgage prepayments can also lead to larger than anticipated demands on the Company’s liquidity from its lending counterparties, as more fully described below.  Additionally, periods of high prepayments can adversely affect pricing for Agency Securities in general and, as a result, book value per common share can be adversely affected due to declines in the fair value of the Company’s remaining portfolio and the elimination of any unrealized gains on that portion of the portfolio that prepays.

Changes in interest rates, whether increases or decreases, may adversely affect Capstead’s liquidity, financial condition and earnings.Capstead’s earnings depend primarily on the difference between the interest received on its residential mortgage investments and the interest paid on its related borrowings, net of the effect of derivatives held for hedging purposes.  The Company finances its investments primarily at 30- to 90-day interest rates.  Coupon interest rates on only a portion of the ARM loans underlying the Company’s securities reset each month and the terms of these ARM loans generally limit the amount of any increases during any single interest rate adjustment period and over the life of a loan.  Consequently, interest rates on related borrowings not effectively fixed through the use of interest rate swap agreements can rise to levels that may exceed yields on these securities in a rising short-term interest rate environment.  This can contribute to lower, or in more extreme circumstances, negative financing spreads and, therefore, adversely affect earnings.  Because rising interest rates tend to put downward pressure on financial asset prices, Capstead may be presented with substantial margin calls during such periods adversely affecting the Company’s liquidity.  If the Company is unable or unwilling to pledge additional collateral, the Company’s lenders can liquidate the Company’s collateral, potentially under adverse market conditions, resulting in losses.  At such times the Company may determine that it is prudent to sell assets to improve its ability to pledge sufficient collateral to support its remaining repo borrowings, which could result in losses.  In addition, lower pricing levels for remaining holdings of residential mortgage investments will lead to declines in book value per common share.

During periods of relatively low short-term interest rates, declines in the indices used to determine coupon interest rate resets for ARM loans may adversely affect yields on the Company's ARM securities as the underlying ARM loans reset at lower rates.  If declines in these indices exceed declines in the Company’s borrowing rates, earnings would be adversely affected.

-34-

Periods of illiquidity in the mortgage markets may reduce amounts available to be borrowed under repurchase arrangements due to declines in the perceived value of related collateral, which could adversely impact Capstead’s liquidity, financial condition and earnings. Capstead generally finances its residential mortgage investments by pledging them as collateral under uncommitted repurchase arrangements, the terms and conditions of which are negotiated on a transaction-by-transaction basis.  The amount borrowed under a repurchase arrangement is limited to a percentage of the estimated market value of the pledged collateral and is specified at the inception of the transaction.  The portion of the pledged collateral held by the lender that is not advanced under the repurchase arrangement is referred to as margin collateral and the resulting margin percentage is required to be maintained throughout the term of the borrowing.  If the perceived market value of the pledged collateral as determined by the Company’s lenders declines, the Company may be subject to margin calls wherein the lender requires the Company to pledge additional collateral to reestablish the agreed-upon margin percentage.  Because market illiquidity tends to put downward pressure on asset prices, Capstead may be presented with substantial margin calls during such periods.  If the Company is unable or unwilling to pledge additional collateral, the Company’s lenders can liquidate the Company’s collateral, potentially under adverse market conditions, resulting in losses.  At such times the Company may determine that it is prudent to sell assets to improve its ability to pledge sufficient collateral to support its remaining repo borrowings, which could result in losses.  In addition, lower pricing levels for remaining holdings of residential mortgage investments will lead to declines in book value per common share.

Periods of illiquidity in the mortgage markets may reduce the number of counterparties willing to lend to the Company and/or the amounts individual counterparties are willing to lend via repurchase arrangements, which could adversely affect the Company’s liquidity, financial condition and earnings.Capstead enters into repurchase arrangements with numerous commercial banks and other financial institutions, both foreign and domestic, routinely with maturities of 30 to 90 days.  The Company’s ability to achieve its investment objectives depends on its ability to re-establish or roll maturing repo borrowings on a continuous basis and none of the Company’s counterparties are obligated to enter into new repurchase transactions at the conclusion of existing transactions.  If a counterparty chooses not to roll a maturing borrowing, the Company must pay off the borrowing, generally with cash available from another repurchase arrangement entered into with another counterparty.  If the Company determines that it does not have sufficient borrowing capacity with its remaining counterparties, it could be forced to reduce its portfolio leverage by selling assets under potentially adverse market conditions, resulting in losses.  This risk is increased if Capstead relies on any single counterparty for a significant portion of its repo borrowings.  An industry-wide reduction in the availability of repo borrowings could adversely affect pricing levels for Agency Securities leading to further declines in the Company’s liquidity and book value per common share.  Under these conditions, the Company may determine that it is prudent to sell assets to improve its ability to pledge sufficient collateral to support its remaining borrowings, which could result in losses.  In addition, lower pricing levels for remaining holdings of residential mortgage investments will lead to declines in book value per common share.

If Capstead is unable to negotiate favorable terms and conditions on future repo borrowings with one or more of the Company’s lending counterparties, the Company’s liquidity, financial condition and earnings could be adversely impacted. The terms and conditions of each repurchase arrangement are negotiated on a transaction-by-transaction basis, and these borrowings generally are re-established, or rolled, at maturity. Key terms and conditions of each transaction include interest rates, maturity dates, asset pricing procedures and margin requirements.  The Company cannot assure investors that it will be able to continue to negotiate favorable terms and conditions on its future repo borrowings.  For instance, during periods of market illiquidity or due to perceived credit deterioration of the collateral pledged or the Company itself, a lender may require that less favorable asset pricing procedures be employed, margin requirements be increased and/or may choose to limit or completely curtail lending to the Company.  Under these conditions, the Company may determine it is prudent to sell assets to improve its ability to pledge sufficient collateral to support its remaining repo borrowings, which could result in losses.

-35-

Capstead’s use of repo borrowings to finance its investments may expose the Company to losses if a lending counterparty seeks bankruptcy protection, or otherwise defaults on its obligation to deliver pledged collateral back to the Company.  Repurchase arrangements involve the sale and transfer of pledged collateral to the lending counterparty and a simultaneous agreement to repurchase the transferred assets at a future date.  This may make it difficult for the Company to recover its pledged assets if a lender files for bankruptcy or otherwise fails to deliver pledged collateral back to the Company and subject the Company to losses to the extent of any margin amounts (pledged assets in excess of amounts borrowed) held by the lending counterparty.

Capstead’s use of repo borrowings to finance its investments may give the Company’s lending counterparties greater rights if the Company seeks bankruptcy protection, exposing the Company to losses.  Repo borrowings may qualify for special treatment under the U.S. Bankruptcy Code.  If the Company files for bankruptcy, its lending counterparties could avoid the automatic stay provisions of the U.S. Bankruptcy Code and liquidate pledged collateral without delay, which could result in losses to the extent of any margin amounts held by the lending counterparties.

Capstead may sell assets for various reasons, including a change in the Company’s investment focus, which could increase earnings volatility.Capstead may periodically sell assets to enhance its liquidity during periods of market illiquidity or rising interest rates or the Company may change its investment focus requiring it to sell some portion of its existing investments.  Gains or losses resulting from any such asset sales, or from terminating any related longer-dated repo borrowings or interest rate swap agreements, could increase the Company’s earnings volatility.

Capstead may invest in derivative financial instruments such as interest rate swap agreements to mitigate or hedge the Company's interest rate risk, which may adversely affect the Company’s liquidity, financial condition or earnings. The Company may invest in such instruments from time to time with the goal of achieving more stable borrowing costs over an extended period.  However, these activities may not have the desired beneficial impact on the Company's liquidity, financial condition or earnings.  For instance, the pricing of residential mortgage investments and the pricing of related derivatives may deteriorate at the same time leading to margin calls by counterparties to both the borrowings supporting these investments and the derivatives, adversely impacting the Company's liquidity and financial condition.  In addition, counterparties could fail to honor their commitments under the terms of the derivatives or have their credit quality downgraded impairing the value of the derivatives.  In the event of any defaults by counterparties, the Company may have difficulty recovering its cash collateral receivable from its counterparties and may not receive payments provided for under the terms of the derivatives and as a result, the Company may incur losses.  No such hedging activity can completely insulate the Company from the risks associated with changes in interest rates and prepayment rates.

Derivative financial instruments held may fail to qualify for hedge accounting introducing potential volatility to Capstead’s earnings.The Company typically qualifies derivative financial instruments held as cash flow hedges for accounting purposes in order to record the effective portion of the change in fair value of derivatives as a component of stockholders’ equity rather than in earnings.  If the hedging relationship for any derivative held ceases to qualify for hedge accounting treatment for any reason, including failing to meet documentation and ongoing hedge effectiveness requirements, the Company would be required to record in earnings the total change in fair value of any such derivative.  In addition the Company could elect to no longer avail itself of cash flow hedge accounting for its derivative positions.  Such changes could introduce a potentially significant amount of volatility to earnings reported by the Company.

-36-

The lack of availability of suitable investments at attractive pricing may adversely affect Capstead’s earnings.The pricing of investments is determined by a number of factors including interest rate levels and expectations, market liquidity conditions, and competition among investors for these investments, many of whom have greater financial resources and lower return requirements than Capstead.  Additionally, in recent years the federal government, primarily through the Federal Reserve, has been an active buyer of Agency Securities which has had the effect of supporting, if not increasing, pricing for these securities.  To the extent the proceeds from prepayments on Capstead’s mortgage investments are not reinvested or cannot be reinvested at rates of return at least equal to the rates previously earned on those investments, the Company's earnings may be adversely affected. Similarly, if proceeds from capital raising activities are not deployed or cannot be deployed at rates of return being earned on existing capital, earnings may be adversely affected.  Capstead cannot assure investors that the Company will be able to acquire suitable investments at attractive pricing and in a timely manner to replace portfolio runoff as it occurs or to deploy new capital as it is raised.  Neither can the Company assure investors that it will maintain the current composition of its investments, consisting primarily of ARM Agency Securities.

Monetary policy actions by the Federal Reserve could adversely affect Capstead’s liquidity, financial condition and earnings. Since 2008 the Federal Reserve has employed a number of new policy initiatives, most notably the purchase of U.S. Treasury securities and Agency Securities.  This expansion of the Federal Reserve’s balance sheet is often referred to as quantitative easing or QE.  The policy goals of the QE initiatives were to support the GSEs and the housing markets, and otherwise improve economic and labor market conditions by exerting downward pressure on longer term interest rates, including mortgage interest rates.

Under the last QE initiative that began in 2012 (referred to as QE3), the Federal Reserve purchased $45 billion a month in long-term Treasury securities and $40 billion a month in fixed-rate Agency Securities, as well as replaced run off of existing holdings of fixed-rate Agency Securities.  In January 2014 the Federal Reserve began reducing purchases of Treasuries and Agency Securities and ceased buying additional Treasury and Agency Securities in November 2014, while continuing to replace portfolio runoff.  The Federal Reserve has indicated that it will continue replacing portfolio runoff until after it begins raising short-term interest rates.

In general, QE elevated pricing levels for Agency Securities resulting in declining yields on new purchases, lower mortgage interest rates and higher mortgage prepayment rates.  The Company’s net interest margins, and therefore earnings, were adversely affected over time as existing, lower-cost portfolio was replaced with higher-cost, lower-yielding securities.  See previous discussion regarding the negative effects of higher mortgage prepayment levels.

With the Federal Reserve concluding its bond buying program and eventually allowing its existing holdings to begin running off, pricing for ARM Agency securities could be negatively affected as the buy-side support of such a large market participant is removed.  In addition, should the Federal Reserve decide to eventually reduce its holdings of fixed-rate Agency Securities through asset sales, the pricing for all Agency Securities could decline.  These actions could adversely affect the Company’s liquidity, earnings and book value per common share, as more fully described above.

Potential changes in the relationship between the federal government and the GSEs could adversely affect Capstead’s liquidity, financial condition and earnings.Agency Securities are considered to have limited, if any, credit risk because the timely payment of principal and interest on these securities are guaranteed by the GSEs, or by Ginnie Mae, an agency of the federal government.  Only the guarantee by Ginnie Mae is explicitly backed by the full faith and credit of the federal government.  The high actual or perceived credit quality of Agency Securities allows the Company to finance its portfolio using repurchase arrangements with favorable interest rate terms and margin requirements that otherwise would not be available.  As a result of deteriorating housing market conditions that began in 2007, the GSEs incurred substantial losses due to high levels of mortgagor defaults and in 2008 the Federal Housing Finance Agency placed the GSEs into conservatorship, allowing it to operate the GSEs without forcing them to liquidate.  Additionally, the federal government, through the U.S. Treasury and the Federal Reserve, undertook other actions to provide financial support to these entities and the housing market including the acquisition of large holdings of Agency Securities.  These and other steps taken by the federal government were designed to support market stability and mortgage availability at favorable rates in part by providing additional confidence to investors in Agency Securities.

-37-

It is anticipated that over the next several years U.S. policy makers will reach a consensus on what the long-term role of the federal government in general, and the GSEs in particular, will have in the housing markets.  In this regard there have been numerous proposals put forth by members of Congress, the Treasury Department and federal regulators regarding GSE reform.  The actual or perceived credit quality of Agency Securities could be adversely affected by market uncertainty over any legislative or regulatory initiatives that impact the relationship between the GSEs and the federal government.  A significantly reduced role by the federal government or other changes in the guarantees provided by Ginnie Mae, the GSEs or their successors could adversely affect the credit profile and pricing of existing holdings and/or future issuances of Agency Securities and whether the Company’s strategy of holding a leveraged portfolio of Agency Securities remains viable, which could adversely affect earnings and book value per common share.

Failure of the federal government to reduce future annual federal budget deficits could adversely impact Capstead’s liquidity, financial condition and earnings. The increasing amount of outstanding federal debt relative to the size of the U.S. economy, particularly in light of projected growth in federal government spending and resulting federal budget deficits, could eventually lead to a decline in the market’s perception of the creditworthiness of the federal government.  Because market participants rely on the federal government’s continued support of the GSEs, the perception of credit risk associated with Agency Securities and, therefore, the pricing of existing holdings of Agency Securities could be adversely affected.  In addition, political discord over the U.S. fiscal policy could create broader financial turmoil and uncertainty, which may weigh heavily on the global banking system and limit the availability and/or terms and conditions of repo borrowings which could adversely impact the Company’s liquidity, earnings and book value per common share, as more fully described above.

Legislative and regulatory actions could adversely affect the availability and/or terms and conditions of borrowings under repurchase arrangements and consequently, the Company’s liquidity, financial condition and earnings.In 2010 the U.S. Congress enacted the Dodd Frank Wall Street Reform and Consumer Protection Act (“Dodd Frank”) in order to restrict certain business practices of systemically significant participants in the financial markets, which include many of the Company’s lending counterparties.  Additionally, changes in regulatory capital requirements and other leverage constraints are being implemented worldwide.  It remains unclear how significant of an impact Dodd Frank and changes in regulatory capital requirements will have on the financial markets in general and on the Company’s strategy of holding a leveraged portfolio of Agency Securities.  However, it is possible that the availability and/or terms and conditions of repo borrowings could be adversely affected which could adversely affect the Company’s liquidity, earnings and book value per common share, as more fully described above.

Capstead is dependent on its executives and employees and the loss of one or more of its executive officers could harm the Company's business and its prospects. As a self-managed REIT with 13 full-time employees and one part-time employee, Capstead is dependent on the efforts of its key officers and employees, most of whom have significant experience in the mortgage industry.  Although the Company's named executive officers and some of its other employees are parties to severance agreements, the Company's key officers and employees are not subject to employment agreements with non-compete clauses, nor has Capstead acquired key man life insurance policies on any of these individuals.  The loss of any of their services could have an adverse effect on the Company's operations.

Risks Related to Capstead’s Status as a REIT and Other Tax Matters

If Capstead does not qualify as a REIT, the Company will be subject to tax as a regular corporation and face substantial tax liability.Capstead has elected to be taxed as a REIT for federal income tax purposes and intends to continue to so qualify.  Qualification as a REIT involves the application of highly technical and complex Internal Revenue Code provisions for which only a limited number of judicial or administrative interpretations exist.  Even a technical or inadvertent mistake could jeopardize the Company's REIT status.  Furthermore, new tax legislation, administrative guidance or court decisions, in each instance potentially with retroactive effect, could make it more difficult or impossible for the Company to qualify as a REIT.

If Capstead fails to qualify as a REIT in any tax year, then:

· The Company would be taxed as a regular domestic corporation, which, among other things, means that the Company would be unable to deduct dividends paid to its stockholders in computing taxable income and would be subject to federal income tax on its taxable income at regular corporate rates;

· Any resulting tax liability could be substantial and would reduce the cash available for distribution to stockholders, and the Company would not be required to make income distributions; and

· Unless Capstead were entitled to relief under applicable statutory provisions, the Company would be disqualified from treatment as a REIT for the subsequent four taxable years and, as a result, the Company’s cash available for distribution to stockholders would be reduced during these years.

Even if Capstead remains qualified as a REIT, the Company may face other tax liabilities that reduce its earnings. Even if Capstead remains qualified for taxation as a REIT, the Company may be subject to certain federal, state and local taxes on its income and assets.  For example, the Company:

· will be required to pay tax on any undistributed REIT taxable income,

· may be subject to the “alternative minimum tax” on any tax preference items, and

· may operate taxable REIT subsidiaries subject to tax on any taxable income earned.

Complying with REIT requirements may limit Capstead’s ability to hedge effectively.The REIT provisions of the Code may limit Capstead’s ability to hedge mortgage securities and related borrowings by requiring it to limit its income in each year from unqualified hedges together with any other income not generated from qualified real estate assets, to no more than 25% of gross income.  In addition, the Company must limit its aggregate income from nonqualified hedging transactions, from providing certain services, and from other non-qualifying sources to not more than 5% of annual gross income. As a result, the Company may have to limit its use of advantageous hedging techniques.  This could result in greater risks associated with changes in interest rates than the Company would otherwise incur.  If the Company were to violate the 25% or 5% limitations, it may have to pay a penalty tax equal to the amount of gross income in excess of those limitations, multiplied by a fraction intended to reflect the profitability of these transactions or activities.  If the Company fails to satisfy the REIT gross income tests it could lose its REIT status for federal income tax purposes unless the failure was due to reasonable cause and not due to willful neglect.

Complying with REIT requirements may cause Capstead to forego otherwise attractive opportunities.  To qualify as a REIT for federal income tax purposes, Capstead must continually satisfy tests concerning, among other things, the sources of its income, the nature and diversification of its assets, the amounts that it distributes to its stockholders, and the ownership of its stock.  The Company may be required to make distributions to stockholders at disadvantageous times or when it does not have funds readily available for distribution.  As a result, compliance with the REIT requirements may hinder the Company's ability to operate solely on the basis of maximizing profits.

-39-

Complying with REIT requirements may force Capstead to liquidate otherwise attractive investments.To qualify as a REIT, Capstead must also ensure that at the end of each calendar quarter at least 75% of the value of its assets consists of cash, cash items, United States government securities and qualified REIT real estate assets.  The remainder of the Company's investments in securities (other than government securities and qualified real estate assets) generally cannot include more than 10% of the outstanding voting securities of any one issuer or more than 10% of the total value of the outstanding securities of any one issuer. In addition, in general, no more than 5% of the value of the Company's assets (other than government securities and qualified real estate assets) can consist of the securities of any one issuer, and no more than 25% of the value of its total securities can be represented by securities of one or more taxable REIT subsidiaries.  If the Company fails to comply with these requirements at the end of any calendar quarter, it must correct such failure within 30 days after the end of the calendar quarter to avoid losing its REIT status and suffering adverse tax consequences.  As a result, the Company may be required to liquidate otherwise attractive investments.

Complying with REIT requirements may force Capstead to borrow to make distributions to stockholders.As a REIT, Capstead must distribute at least 90% of its annual taxable income (subject to certain adjustments) to its stockholders.  To the extent that the Company satisfies the distribution requirement, but distributes less than 100% of its taxable income, the Company will be subject to federal corporate income tax on its undistributed taxable income.  In addition, the Company will be subject to a 4% nondeductible excise tax if the actual amount that it pays out to its stockholders in a calendar year is less than a minimum amount specified under the federal tax laws.  From time to time, the Company may generate taxable income greater than its net income for financial reporting purposes or its taxable income may be greater than the Company's cash flow available for distribution to stockholders.  If the Company does not have other funds available in these situations, it could be required to borrow funds, sell investments at disadvantageous prices or find another alternative source of funds to make distributions sufficient to enable it to pay out enough of its taxable income to satisfy the distribution requirement and to avoid corporate income tax or the 4% excise tax in a particular year.  These alternatives could increase the Company's costs and reduce its long-term investment capital.

Capstead may be subject to adverse legislative or regulatory tax changes that could reduce the market price of the Company’s securities. Federal income tax laws or the administrative interpretations of those laws can change at any time.  Any such changes in laws or interpretations thereof may apply retroactively and could adversely affect Capstead or its stockholders.  Capstead cannot predict any impact on the value of its securities from adverse legislative or regulatory tax changes.

An investment in Capstead’s securities has various federal, state and local income tax risks that could affect the value of an investor’s investment.The Company strongly urges investors to consult their own tax advisor concerning the effects of federal, state and local income tax law on an investment in the Company's securities, because of the complex nature of the tax rules applicable to REITs and their stockholders.

Risk Factors Related to Capstead’s Corporate Structure

There are no assurances of Capstead’s ability to pay dividends in the future.Capstead intends to continue paying quarterly dividends and to make distributions to its stockholders in amounts such that all or substantially all of the Company's taxable income in each year, subject to certain adjustments, is distributed.  This, along with other factors, should enable the Company to qualify for the tax benefits accorded to a REIT under the Internal Revenue Code.  However, the Company's ability to pay dividends may be adversely affected by the risk factors described in this filing.  All distributions will be made at the discretion of the Company's board of directors and will depend upon the Company’s earnings, its financial condition, maintenance of its REIT status and such other factors as the board may deem relevant from time to time.  There are no assurances of the Company's ability to pay dividends in the future.

-40-

Failure to maintain an exemption from the Investment Company Act of 1940 would adversely affect Capstead’s results of operations.The Investment Company Act of 1940 (the “40 Act”) exempts from regulation as an investment company any entity that is primarily engaged in the business of purchasing or otherwise acquiring mortgages and other liens on, and interests in, real estate. Capstead believes that it conducts its business in a manner that allows the Company to avoid registration as an investment company under the 40 Act.  For over 30 years, the staff of the SEC has interpreted the provisions of the 40 Act to require, among other things, a REIT to maintain at least 55% of its assets directly in qualifying real estate interests and at least 80% of its assets in real estate-related assets in order to be exempt from regulation as an investment company.  Critical to Capstead’s exemption from regulation as an investment company is the long-standing SEC staff interpretation that so called whole loan mortgage securities, in which an investor holds all issued certificates with respect to an underlying pool of mortgage loans, constitutes a qualifying real estate interest for purposes of the staff’s 55% qualifying real estate interest requirement.

Conversely, so called partial pool mortgage securities presently do not qualify for purposes of meeting the 55% requirement, although they are considered by the staff to be real estate-related assets for purposes of meeting the staff’s 80% real estate-related asset requirement.

In August 2011, the SEC staff issued a request for information (Concept Release No. IC-29778) from industry participants and investors regarding, among other things, its past interpretations of the 40 Act real estate exemption, including the interpretations described above, raising concerns that the SEC may issue a proposal for rulemaking that could overturn some of the staff’s past interpretations regarding the real estate exemption.  If the SEC or its staff adopts contrary interpretations of the 40 Act and the Company and other similar REITs become subject to regulation as investment companies, the industry’s use of leverage would be substantially reduced.  Absent a restructuring of the Company’s business operations to avoid such regulation, this could require the sale of most of the Company’s portfolio of Agency Securities under potentially adverse market conditions resulting in losses and significantly reduce future net interest margins and earnings.

Pursuant to Capstead’s charter, its board of directors has the ability to limit ownership of the Company's capital stock, to the extent necessary to preserve its REIT qualification.For the purpose of preserving Capstead’s REIT qualification, the Company’s charter gives the board the ability to repurchase outstanding shares of capital stock from existing stockholders if the directors determine in good faith that the concentration of ownership by such individuals, directly or indirectly, would cause the Company to fail to qualify or be disqualified as a REIT. Constructive ownership rules are complex and may cause the outstanding stock owned by a group of related individuals or entities to be deemed to be constructively owned by one individual or entity.  As a result, the acquisition of outstanding stock by an individual or entity could cause that individual or entity to own constructively a greater concentration of the Company's outstanding stock than is acceptable for REIT purposes, thereby giving the board the ability to repurchase any excess shares.

Because provisions contained in Maryland law and Capstead’s charter may have an anti-takeover effect, investors may be prevented from receiving a “control premium” for their shares. Provisions contained in Capstead’s charter and Maryland general corporation law can delay, defer or prevent a takeover attempt, which may prevent stockholders from receiving a “control premium” for their shares.  For example, these provisions may defer or prevent tender offers for the Company's common stock or purchases of large blocks of the Company's common stock, thereby limiting the opportunities for its stockholders to receive a premium over then-prevailing market prices.  These provisions include the following:

-41-

· Repurchase rights:   Repurchase rights granted to Capstead’s board in its charter limit related investors, including, among other things, any voting group, from owning common stock if the concentration owned would jeopardize the Company's REIT status.

· Classification of preferred stock:  Capstead’s charter authorizes the board to issue preferred stock and establish the preferences and rights of any class of preferred stock issued.  These actions can be taken without soliciting stockholder approval and could have the effect of delaying or preventing someone from taking control of the Company.

· Statutory provisions: Capstead is subject to provisions of Maryland statutory law that restrict business combinations with interested stockholders and restrict voting rights of certain shares acquired in control share acquisitions.  The board has not taken any action to exempt the Company from these provisions.

Maryland statutory law provides that an act of a director relating to or affecting an acquisition or a potential acquisition of control of a corporation may not be subject to a higher duty or greater scrutiny than is applied to any other act of a director.  Hence, directors of Maryland corporations may not be required to act in takeover situations under the same standards as apply in Delaware and certain other corporate jurisdictions.

There are risks associated with ownership of Capstead’s Series E Preferred Stock.Risks associated with ownership of the Company’s Series E preferred stock include:

· Redemption rights:  The Series E preferred stock is redeemable by the Company, in whole or in part, at any time on or after May 13, 2018, or pursuant to a Special Optional Redemption Right upon the occurrence of a Change of Control, as both terms are defined in the Series E Articles Supplementary, at a cash redemption price of $25.00 plus all accrued and unpaid dividends to, but not including, the date of redemption, which may be less than the prevailing market price for shares of the Series E preferred stock.

· Limited conversion rights:Holders of shares of the Series E preferred stock may convert into shares of common stock only upon the occurrence of a Change of Control, and only if the Company does not exercise its Special Optional Redemption Right.  Even if this were to occur, it may not be economically advantageous to convert based on then existing conversion ratios and trading levels of the common stock.

· Subordination:The Series E preferred stock is subordinate to all of the Company’s existing and future debt.  None of the provisions relating to the Series E preferred stock limit the Company’s ability to incur future debt.  Future debt may include restrictions on the Company’s ability to pay dividends on, redeem, or pay the liquidation preference on shares of the Series E preferred stock.

· Dilution through issuance of additional shares of preferred stock:The Company’s charter currently authorizes the issuance of up to 100 million shares of preferred stock in one or more series. The issuance of additional preferred stock on parity with or senior to the Series E preferred stock would dilute the interests of Series E preferred stockholders, and could affect the Company’s ability to pay dividends on, redeem, or pay the liquidation preference on, the Series E preferred stock.  None of the provisions relating to the Series E preferred stock limit the Company’s ability to issue additional preferred stock on parity with Series E preferred stock.

-42-

· Limited voting rights:  Voting rights as a holder of Series E preferred stock are limited.  The Company’s common stock is currently the only class of stock carrying full voting rights. Voting rights for holders of shares of Series E preferred stock exist primarily with respect to (i) adverse changes in the terms of the Series E preferred stock, (ii) the creation of additional classes or series of preferred stock that are senior to the Series E preferred stock, and (iii) the non-payment of six quarterly dividends (whether or not consecutive) are in arrears.

Capstead may change its policies without stockholder approval.Capstead’s board and management determine all of its policies, including its investment, financing and distribution policies and may amend or revise these policies at any time without a vote of the Company's stockholders.  Policy changes could adversely affect the Company's financial condition, results of operations, the market price of its common and preferred stock or the Company's ability to pay dividends or distributions.

CRITICAL ACCOUNTING POLICIES

Management’s discussion and analysis of financial condition and results of operations is based upon Capstead’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States.  The preparation of these financial statements requires the use of estimates and judgments that can affect the reported amounts of assets, liabilities (including contingencies), revenues and expenses, as well as related disclosures.  These estimates are based on available internal and market information and appropriate valuation methodologies believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the expected useful lives and carrying values of assets and liabilities which can materially affect the determination of net income and book value per common share.  Actual results may differ from these estimates under different assumptions or conditions.

Management believes the following are critical accounting policies in the preparation of Capstead’s consolidated financial statements that involve the use of estimates requiring considerable judgment:

· Amortization of investment premiums on residential mortgage investments – Investment premiums on residential mortgage investments are recognized in earnings as adjustments to interest income by the interest method over the estimated lives of the related assets.  The single largest determinant in amortizing investment premiums is actual portfolio runoff (scheduled and unscheduled principal paydowns) for a given accounting period.  This is because the investment premium associated with actual runoff is amortized when the runoff occurs pursuant to the interest method.  Amortization is also affected by estimates and judgments related to future levels of mortgage prepayments used in determining additional amortization that may be necessary to achieve the required effective yield over the estimated life of the related investment.

Mortgage prepayment expectations can change based on how current and projected changes in interest rates impact the economic attractiveness of mortgage refinance opportunities, if available, and other factors such as lending industry underwriting practices and capacity constraints, regulatory changes, borrower credit profiles and the health of the economy and housing markets.  Management estimates mortgage prepayments based these factors and past experiences with specific investments within the portfolio.  Should actual prepayment rates differ materially from these estimates, investment premiums would be expensed at a different pace.

· Fair value and impairment accounting for residential mortgage investments – Nearly all of Capstead’s residential mortgage investments are held in the form of mortgage securities that are classified as available-for-sale and recorded at fair value on the balance sheet with unrealized gains and losses recorded in Stockholders’ equity as a component of Accumulated other comprehensive income.  As such, these unrealized gains and losses enter into the calculation of book value per common share, a key financial metric used by investors in evaluating the Company.  Fair values fluctuate with current and projected changes in interest rates, prepayment expectations and other factors such as market liquidity conditions and the perceived credit quality of Agency Securities.  Judgment is required to interpret market data and develop estimated fair values, particularly in circumstances of deteriorating credit quality and market liquidity.  See NOTE 9 to the consolidated financial statements (included under Item 1 of this report) for discussion of how Capstead values its residential mortgage investments.

-43-

Generally, gains or losses are recognized in earnings only if securities are sold; however, if a decline in fair value of a mortgage security below its amortized cost occurs that is determined to be other-than-temporary, the difference between amortized cost and fair value would be recognized in earnings as a component of Other revenue (expense) if the decline was credit-related or it was determined to be more likely than not that the Company will incur a loss via an asset sale.  Other-than-temporary impairment of a mortgage security due to other factors would be recognized in Accumulated other comprehensive income.

· Accounting for derivative financial instruments – Capstead uses derivatives for risk management purposes.  Derivatives are recorded as assets or liabilities and carried at fair value and consequently, changes in value of these instruments enter into the calculation of book value per common share.  Fair values fluctuate with current and projected changes in interest rates and other factors such as the Company’s and its counterparties’ nonperformance risk.  Judgment is required to develop estimated fair values.

The accounting for changes in fair value of each derivative held depends on whether it has been designated as an accounting hedge, as well as the type of hedging relationship identified.  To qualify as a cash flow hedge for accounting purposes, at the inception of the hedge relationship the Company must anticipate and document that the hedge relationship will be highly effective and must monitor ongoing effectiveness on at least a quarterly basis.  As long as the hedge relationship remains effective, the effective portion of changes in fair value of the derivative is recorded in Accumulated other comprehensive income and the ineffective portion is recorded in earnings as a component of Interest expense.  The effective portion of changes in fair value is reclassified from Accumulated comprehensive income to earnings over the term of the derivative primarily in the form of derivative cash flows that are either in excess of or lower than market rates.  Changes in fair value of derivatives not held as accounting hedges, or for which the hedge relationship is deemed to no longer be highly effective and as a result hedge accounting is terminated, are recorded in earnings as a component of Other revenue (expense).

The Company currently uses interest rate swap agreements in hedge relationships accounted for as cash flow hedges in order to hedge variability in borrowing rates due to changes in the underlying benchmark interest rate related to a designated portion of its current and anticipated future 30- and 90-day borrowings and the 20-year floating-rate periods of the Company’s unsecured borrowings that begin in late 2015.  Variable-rate payments to be received on the swap agreements and any measured hedge ineffectiveness are recorded in interest expense as an offset to interest owed on the hedged borrowings that reset to market rates generally on a monthly basis while fixed rate swap payments to be made are also recorded in interest expense resulting in an effectively fixed borrowing rate on these borrowings, subject to certain adjustments.  See NOTE 6 to the consolidated financial statements (included under Item 1 of this report) and “Financial Condition–Residential Mortgage Investments” for additional information regarding the Company’s current use of derivatives and its related risk management policies.

CERTIFICATION PURSUANT TO SECTION 302(a)

NET INCOME PER COMMON SHARE

NET INCOME PER COMMON SHARE [Abstract]

NET INCOME PER COMMON SHARE

NOTE 3 ¾ NET INCOME PER COMMON SHARE

Basic net income per common share is computed by dividing net income, after deducting dividends paid or accrued on preferred stock and allocating earnings to equity awards deemed to be participating securities pursuant to the two-class method, by the weighted average number of shares of common stock outstanding, calculated excluding unvested stock awards.  Participating securities include any unvested equity awards that contain non-forfeitable rights to dividends prior to vesting.

Diluted net income per common share is computed by dividing the numerator used to compute basic net income per common share by the denominator used to compute basic net income per common share, further adjusted for the dilutive effect, if any, of equity awards and shares of preferred stock when and if convertible into shares of common stock.  Shares of the Company’s 7.50% Series E Cumulative Redeemable Preferred Stock are contingently convertible into shares of common stock only upon the occurrence of a change in control and therefore are not considered dilutive securities absent such an occurrence.  Any unvested equity awards that are deemed participating securities are included in the calculation of diluted net income per common share, if dilutive, under either the two-class method or the treasury stock method, depending upon which method produces the more dilutive result.

Components of the computation of basic and diluted net income per common share were as follows for the indicated periods (dollars in thousands, except per share amounts):

	Quarter Ended March 31

Interim Financial Reporting and Reclassifications

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.  In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.  Operating results for the quarter ended March 31, 2015 are not necessarily indicative of the results that may be expected for the calendar year ending December 31, 2015.  For further information refer to the audited consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2014.

Recent Accounting Pronouncements

In June 2014 the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-11, Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings and Disclosures (“ASU 2014-11”).  ASU 2014-11 requires repurchase-to-maturity transactions to be accounted for as financings and eliminates existing guidance regarding so-called “linked transactions” between a buyer of securities and a seller that also provides related repurchase financings.  ASU 2014-11 also introduces new disclosure requirements and is effective for periods beginning after December 15, 2014.  The Company adopted ASU 2014-11 in the current quarter.  As the Company has not entered into any repurchase-to-maturity or linked transactions, the provisions of this ASU had no effect on the Company’s results of operations, financial condition, or cash flows.

(a) Includes unrealized gains and losses for residential mortgage investments classified as available-for-sale (see NOTE 9).

(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.

USE OF DERIVATIVE FINANCIAL INSTRUMENTS, OFFSETTING DISCLOSURES AND CHANGES IN OTHER COMPREHENSIVE INCOME BY COMPONENT

NOTE 6 ¾ USE OF DERIVATIVE FINANCIAL INSTRUMENTS, OFFSETTING DISCLOSURES AND CHANGES IN OTHER COMPREHENSIVE INCOME BY COMPONENT

To help mitigate exposure to higher interest rates, Capstead typically uses currently-paying and forward-starting, one-month LIBOR-indexed, pay-fixed, receive-variable, interest rate swap agreements that require interest payments for two-year terms.  These Derivatives are designated as cash flow hedges of the variability of the underlying benchmark interest rate of current and forecasted 30- to 90-day borrowings under repurchase arrangements.  This hedge relationship establishes a relatively stable fixed rate on related borrowings because the variable-rate payments received on the swap agreements offset a significant portion of the interest accruing on the related borrowings, leaving the fixed-rate swap payments as the Company’s effective borrowing rate, subject to certain adjustments.  These adjustments include differences between variable-rate payments received on the swap agreements and related unhedged borrowing rates as well as the effects of measured hedge ineffectiveness.  Additionally, changes in fair value of these Derivatives tend to partially offset opposing changes in fair value of the Company’s residential mortgage investments that can occur in response to changes in market interest rates.

During the quarter ended March 31, 2015 Capstead entered into swap agreements with notional amounts of $700 million.  These swap agreements require fixed-rate interest payments averaging 0.71% for two-year periods commencing on various dates between January 2015 and April 2015.  Also during the current quarter, $1.10 billion notional amount of swaps requiring fixed-rate interest payments averaging 0.50% matured, while $500 million notional amount of forward-starting swaps requiring fixed-rate interest payments averaging 0.72% moved into current-pay status.

At March 31, 2015, the Company’s portfolio of financing-related swap positions had the following characteristics (dollars in thousands):

Period of Contract Expiration	Notional Amount		Average Fixed Rate Payment Requirement
Currently-paying contracts:
Second quarter 2015	$	200,000		0.43	%
Third quarter 2015		400,000		0.47
Fourth quarter 2015		1,200,000		0.45
First quarter 2016		1,700,000		0.51
Second quarter 2016		1,100,000		0.47
Third quarter 2016		700,000		0.56
Fourth quarter 2016		800,000		0.66
First quarter 2017		1,000,000		0.72
(average expiration: 12 months)		7,100,000		0.54
Forward-starting contracts:
Second quarter 2017 (average expiration: 24 months)		200,000		0.72
(average expiration: 12 months)	$	7,300,000

In addition to portfolio financing-related swap positions, in 2010 the Company entered into three forward-starting, three-month LIBOR-indexed, pay-fixed, receive-variable, interest rate swap agreements with notional amounts totaling $100 million and average fixed rates of 4.09% with 20-year payment terms coinciding with the floating-rate terms of the Company’s Unsecured borrowings which begin between October 30, 2015 and September 15, 2016.  These Derivatives are designated as cash flow hedges of the variability of the underlying benchmark interest rate associated with the floating-rate terms of these long-term borrowings (see NOTE 7).

Interest rate swap agreements are measured at fair value on a recurring basis primarily using Level Two Inputs in accordance with ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820).  In determining fair value estimates for these Derivatives, Capstead utilizes the standard methodology of netting the discounted future fixed cash payments and the discounted future variable cash receipts which are based on expected future interest rates derived from observable market interest rate curves.  Related net interest payable at the balance sheet date is recorded separately.  The Company also incorporates both its own nonperformance risk and its counterparties’ nonperformance risk in determining the fair value of these Derivatives.  In considering the effect of nonperformance risk, the Company considered the impact of netting and credit enhancements, such as collateral postings and guarantees, and has concluded that counterparty risk is not significant to the overall valuation of these agreements.

The following tables include fair value and other related disclosures regarding all Derivatives held as of and for the indicated periods (in thousands):

REPURCHASE ARRANGEMENTS AND SIMILAR BORROWINGS

NOTE 5 ¾ REPURCHASE ARRANGEMENTS AND SIMILAR BORROWINGS

Capstead pledges its Residential mortgage investments as collateral under repurchase arrangements with commercial banks and other financial institutions, referred to as counterparties, the terms and conditions of which are negotiated on a transaction-by-transaction basis when each such borrowing is initiated or renewed.  Repurchase arrangements entered into by the Company involve the sale and a simultaneous agreement to repurchase the transferred assets at a future date and are accounted for as borrowings.  The Company maintains the beneficial interest in the specific securities pledged during the term of each repurchase arrangement and receives the related principal and interest payments.  The amount borrowed is generally equal to the fair value of the securities pledged, as determined by the lending counterparty, less an agreed-upon discount, referred to as a “haircut.”  Interest rates on these borrowings are fixed based on prevailing rates corresponding to the terms of the borrowings, and interest is paid at the termination of the repurchase arrangement at which time the Company may enter into a new repurchase arrangement at prevailing haircuts and rates with the same counterparty or repay that counterparty and negotiate financing with a different counterparty.  None of the Company’s counterparties are obligated to renew or otherwise enter into new repurchase arrangements at the conclusion of existing repurchase arrangements. In response to declines in fair value of pledged securities due to changes in market conditions or the publishing of monthly security paydown factors, lenders typically require the Company to post additional securities as collateral, pay down borrowings or fund cash margin accounts with the counterparties in order to re-establish the agreed-upon collateral requirements.  These actions are referred to as margin calls.  Conversely, in response to increases in fair value of pledged securities, the Company routinely margin calls its lending counterparties in order to have previously pledged collateral returned to the Company.

Repurchase arrangements and similar borrowings (and related pledged collateral, including accrued interest receivable), classified by collateral type and remaining maturities, and related weighted average borrowing rates as of the indicated dates were as follows (dollars in thousands):

DISCLOSURES REGARDING FAIR VALUES OF FINANCIAL INSTRUMENTS [Abstract]

DISCLOSURES REGARDING FAIR VALUES OF FINANCIAL INSTRUMENTS

NOTE 9 ¾ DISCLOSURES REGARDING FAIR VALUES OF FINANCIAL INSTRUMENTS

This note provides fair value-related disclosures as of the indicated balance sheet dates for Capstead’s financial assets and liabilities, most of which are influenced by changes in, and market expectations for changes in, interest rates and market liquidity conditions, as well as other factors beyond the control of management.  All fair values were determined using Level 2 Inputs in accordance with ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820).

Residential mortgage investments, nearly all of which are mortgage securities classified as available-for-sale, are measured at fair value on a recurring basis.  In determining fair value estimates for mortgage securities, the Company considers recent trading activity for similar investments and pricing levels indicated by lenders in connection with designating collateral for repurchase arrangements, provided such pricing levels are considered indicative of actual market clearing transactions.  In determining fair value estimates for longer-term borrowings under repurchase arrangements, the Company considers pricing levels indicated by lenders for entering into new transactions using similar pledged collateral with terms equal to the remaining terms of the longer-term borrowings.  In determining fair value estimates for unsecured borrowings, the Company considers current pricing for financial instruments with similar characteristics.  Excluded from these disclosures are financial instruments for which the Company’s cost basis is deemed to approximate fair value due primarily to the short duration of these instruments, which are valued using primarily Level 1 measurements, including Cash and cash equivalents, cash collateral receivable from, or payable to, interest rate swap counterparties, receivables, payables and borrowings under repurchase arrangements with initial terms of 120 days or less.  See NOTE 6 for information relative to the valuation of interest rate swap agreements.

	$	937,977	$	4,462	$	1,802,563	$	7,375

Capstead’s investment strategy involves managing a leveraged portfolio of relatively short-duration ARM Agency Securities and management expects these securities will be held until payoff absent a major shift in strategy or a severe contraction in the Company’s ability to obtain financing to support its portfolio.  Declines in fair value caused by increases in interest rates are typically modest for investments in short-duration ARM Agency Securities compared to investments in longer-duration ARM or fixed-rate assets.  These declines are generally recoverable in a relatively short period of time as coupon interest rates on the underlying mortgage loans reset to rates more reflective of the then current interest rate environment.

From a credit risk perspective, federal government support for the GSEs helps ensure that fluctuations in value due to credit risk associated with these securities will be limited.  Given that (a) any existing unrealized losses on mortgage securities held by the Company are not attributable to credit risk and declines in fair value of ARM securities due to changes in interest rates are generally recoverable in a relatively short period of time, (b) the Company typically holds its investments to maturity, and (c) it is more likely than not that the Company will not be required to sell any of its investments given the resiliency of the financing market for Agency Securities, none of these investments are considered other-than-temporarily impaired at March 31, 2015.

UNSECURED BORROWINGS [Abstract]

UNSECURED BORROWINGS

NOTE 7 ¾ UNSECURED BORROWINGS

Unsecured borrowings consist of 30-year junior subordinated notes issued in 2005 and 2006 and maturing in 2035 and 2036.  Included in Receivables and other assets are $2.1 million in remaining issue costs at March 31, 2015 associated with the original issuance of these notes.  Note balances and related weighted average interest rates as of March 31, 2015 and December 31, 2014 (calculated including issue cost amortization) were as follows (dollars in thousands):

	Borrowings Outstanding		Average Rate *
Junior subordinated notes maturing in:
October 2035	$	35,000		8.31	%
December 2035		40,000		8.46
September 2036		25,000		8.78

COMPENSATION PROGRAMS [Abstract]

COMPENSATION PROGRAMS

NOTE 10 ¾ COMPENSATION PROGRAMS

The compensation committee of Capstead’s board of directors (the “Committee”) is responsible for establishing, implementing, and monitoring the Company’s compensation program and practices.  In 2013 the Committee replaced an absolute return-based, discretionary bonus program and an absolute return-based stock award program with largely nondiscretionary and formulaic, target-based annual and long-term incentive compensation programs for key executives with multiple, pre-established performance goals and defined threshold, target and maximum awards as a percentage of base salary.

Equity-based awards as well as other incentive awards that recognize the creation of value for stockholders and promote the Company’s long-term growth and success are made pursuant to the Company’s Amended and Restated 2014 Flexible Incentive Plan, approved by stockholders in May 2014.  At March 31, 2015, this plan had 4,432,739 shares of common stock remaining available for future issuances.

Short-term Incentive Compensation Programs

As more fully described in the Company’s proxy statement, the Committee periodically reviews Capstead’s annual incentive compensation program, establishing and implementing desired changes in performance metrics, composition of the mortgage REIT industry peer group used for measurement purposes and each participating officer’s targeted award opportunity.  Under the provisions of the program in effect for 2015 and 2014, awards are made based on (a) economic return (change in book value plus dividends) measured on a relative basis, and, to a lesser extent, on an absolute return basis, (b) relative operating cost efficiency (operating expenses divided by Unsecured borrowings and Stockholders’ equity), and (c) each participating officer’s attainment of stated goals and objectives.  Each participating officer has a targeted award opportunity equal to 125% of his base salary.  Under the terms of the program, each performance metric is assigned a weighting and the Company’s performance relative to each metric is calculated separately. No awards can be earned for performance below the defined threshold returns and awards are capped for performance above the defined maximum return levels.  Included in Accounts payable and accrued expenses at March 31, 2015 are annual incentive compensation accruals for all employees totaling $489,000.  Recognized in Short-term incentive compensation are $489,000 and $318,000 related to annual incentive compensation for all employees for the quarters ended March 31, 2015 and 2014, respectively.

The Committee administers an additional performance-based short-term incentive compensation program for key executives that provides for quarterly cash payments equal to per share dividends declared on Capstead’s common stock multiplied by a notional amount of non-vesting shares of common stock (“Dividend Equivalent Rights” or “DERs”).  DERs only represent the right to receive the same cash distributions that the Company’s common stockholders are entitled to receive during the term of the grants, subject to certain conditions, including continuous service.  In December 2014 the Committee extended the term of the 654,000 outstanding DERs to December 31, 2015.  Included in Accounts payable and accrued expenses are first quarter 2015 DERs distribution amounts totaling $203,000 that were paid in April 2015.  Recognized in Short-term incentive compensation are $203,000 and $222,000 related to the DERs program for the quarters ended March 31, 2015 and 2014, respectively.

Long-term Equity-based Awards – Performance-based RSUs

The Committee adopted a new performance-based long-term incentive compensation program for key executives in December 2013.  The program provides for the grant of performance-based RSUs that are convertible into common shares following three-year performance periods, contingent upon whether, and to what extent, defined performance levels established for certain relative and absolute return performance metrics are met or exceeded.  The relative return metrics measure the Company’s performance against its peers in the mortgage REIT industry on the basis of relative economic return and relative total stockholder return (change in stock price plus reinvested dividends).  The absolute economic return metric measures performance against defined return levels.  For conversion purposes, each performance metric is assigned a weighting and the Company’s performance relative to each metric is calculated separately.  The actual number of shares of common stock the units can convert into for each of the metrics, if any, can range from one-half of a share per unit if that metric’s minimum threshold of performance is met, to two shares per unit if the related maximum performance threshold is met or exceeded, adjusted for the weighting assigned to the metric.  If a metric’s minimum performance threshold is not met, no shares are issuable under that metric.  Dividends accrue from the date of grant and will be paid in cash when the units convert into shares of common stock based on the number of shares ultimately issued, if any.

Pursuant to this program, in January 2015 and December 2013 the Committee granted 247,512 and 242,505 RSUs with three-year performance periods ending December 31, 2017 and 2016, respectively.  Initial grant date fair values of $8.83 and $12.45 were assigned to each unit of the January 2015 and December 2013 grants, respectively.  In the fourth quarter of 2014 the three-year compensation cost estimate for the December 2013 grant was reduced to $7.21 per unit.  Recognized in Long-term incentive compensation are $328,000 and $251,000 related to the RSUs for the quarters ended March 31, 2015 and 2014, respectively.

Long-term Equity-based Awards – Stock Awards

Under an absolute return performance-based stock award program terminated in 2013, the Committee granted common stock awards to all employees with staggered three-year vesting periods.  These awards vest if annualized returns in excess of established return levels are generated during three-year measurement periods.  Vesting can be deferred and a new three-year measurement period established to include the subsequent year, up to and including the seventh calendar year after the year of grant.  Any remaining unvested awards issued under this program will expire if the required returns are not generated for the final three-year measurement period.  Grants made under this program totaling 125,221 shares with an average grant date fair value of $12.58 vested in February 2015 pertaining to initial measurement periods ending December 31, 2014.  Remaining grants under this program totaling 133,571 and 69,849 shares with average grant date fair values of $12.17 and $11.67 are scheduled to vest in February 2016 and 2017, respectively, assuming performance criteria and service conditions are met.

In December 2014 and 2013 respectively, the Committee granted service-based stock awards for 37,237 and 35,703 shares of common stock with grant date fair values of $12.47 and $12.34 to employees not awarded RSUs.  These awards vest January 2, 2018 and January 2, 2017, respectively, assuming service conditions are met.  In January 2014 the remaining 22,164 shares associated with 2007 service-based stock awards issued to all employees vested.  As a component of the Company’s director compensation program, directors are granted stock awards annually upon election or re-election to the board of directors that vest approximately one year from issuance.  In July 2014, director stock awards for 35,000 shares with a grant date fair value of $13.16 were granted that vest in July 2015, assuming service conditions are met.  In April 2014, director grants awarded in 2013 for 28,000 shares with a grant date fair value of $13.02 vested.

Performance-based and service-based stock award activity for quarter ended March 31, 2015 is summarized below:

	Number of Shares			Weighted Average Grant Date Fair Value
Unvested stock awards outstanding at December 31, 2014		436,581			12.29
Vestings		(125,221	)		12.58
Unvested stock awards outstanding at March 31, 2015		311,360			12.18

During the quarters ended March 31, 2015 and 2014, the Company recognized in Long-term incentive compensation $280,000 and $375,000, respectively, related to amortization of the grant date fair value of employee performance-based and service-based stock awards.  The amounts amortized for these periods assumed that performance metrics, if applicable, would continue to be met for related initial measurement periods.  In addition, the Company recognized in Other general and administrative expense $115,000 and $92,000 related to amortization of the grant date fair value of service-based director stock awards during the quarters ended March 31, 2015 and 2014, respectively.

All service-based stock awards receive dividends on a current basis without risk of forfeiture if the related awards do not vest.  Outstanding performance-based stock awards defer the payment of dividends accruing between the grant dates and the end of related performance periods.  If these awards do not vest, the related accrued dividends will be forfeited.

Long-term Equity-based Awards – Option Awards

Option awards currently outstanding have ten-year contractual terms from the grant date and were issued with strike prices equal to the quoted market prices of Capstead’s common shares on the dates of grant, all of which were prior to 2010.  No option award activity occurred during the quarter ended March 31, 2015.  All outstanding option awards are exercisable at March 31, 2015.  These awards totaled 40,000 shares with a weighted average remaining contractual term of 3.2 years and an aggregate intrinsic value of $13,000.  The fair value of these awards was estimated on the dates of grant using a Black-Scholes option pricing model and was expensed over the related vesting periods.

Other Benefit Programs

Capstead sponsors a qualified defined contribution retirement plan for all employees and a nonqualified deferred compensation plan for certain of its executives.  In general the Company matches up to 50% of a participant’s voluntary contribution up to a maximum of 6% of a participant’s base salary and annual incentive compensation payments and makes discretionary contributions of up to another 3% of such compensation regardless of participation in the plans.  Company contributions are subject to certain vesting requirements that have been met by nearly all of Capstead’s current employees.  During the quarters ended March 31, 2015 and 2014, the Company recognized in Salaries and benefits $75,000 and $64,000 related to contributions to these plans, respectively.

(a) Includes unrealized gains and losses for residential mortgage investments classified as available-for-sale (see NOTE 9).

(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.

Because of federal government support for the GSEs, Agency Securities are considered to have limited, if any, credit risk.  Residential mortgage loans held by Capstead were originated prior to 1995 when the Company operated a mortgage conduit and the related credit risk is borne by the Company.  Collateral for structured financings consists of private residential mortgage securities that are backed by loans obtained through this mortgage conduit and are pledged to secure repayment of related structured financings.  Credit risk for these securities is borne by the related bondholders.  The maturity of Residential mortgage investments is directly affected by prepayments of principal on the underlying mortgage loans.  Consequently, actual maturities will be significantly shorter than the portfolio’s weighted average contractual maturity of 290 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 typically 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 investments based on 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.  A shorter duration generally indicates less interest rate risk.  Current-reset ARM investments have months to roll of less than 18 months while longer-to-reset ARM investments have months to roll of 18 months or greater.  As of March 31, 2015, the average months to roll for the Company’s $7.85 billion (amortized cost basis) in current-reset ARM investments was 6.3 months while the average months to roll for the Company’s $6.03 billion (amortized cost basis) in longer-to-reset ARM investments was 40.0 months.
