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 currently consisting ~~almost exclusively~~primarily of adjustable-rate mortgage (“ARM”) securities issued and guaranteed by government-sponsored enterprises, either Fannie Mae, Freddie Mac, or by an agency of the federal government, Ginnie Mae. ~~Residential mortgage pass-through~~Together these securities ~~guaranteed by Fannie Mae, Freddie Mac or Ginnie Mae~~ are referred to as “Agency Securities” and are considered to have limited, if any, credit risk.

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 ~~and nine months~~ ended ~~September 30, 2017~~March 31, 2021 are not necessarily indicative of the results that may be expected for the calendar year ending December 31, ~~2017.~~2021. 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, ~~2016.~~

In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2016-09, Compensation–Stock Compensation: Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”) with the objective of simplifying accounting for these transactions, including income tax effects, statutory withholding requirements, forfeitures and classification on the statement of cash flows. ASU 2016-09 is effective for public companies for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company adopted ASU 2016-09 on January 1, 2017, which had no effect on its results of operations, financial condition or cash flows.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”) with the objective of improving the financial reporting of hedging relationships by, among other things, eliminating the requirement to separately measure and record hedge ineffectiveness. ASU 2017-12 is effective for public companies for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early application is permitted using a modified retrospective method effective as of the beginning of the fiscal year. The Company elected to early-adopt ASU 2017-12 on August 31, 2017 and, as a result, $863,000 of expense related to hedge ineffectiveness recognized in ~~Interest expense~~ ~~during the six months ended June 30, 2017 on designated swaps outstanding on August 31, 2017 was reversed. Additionally, $105,000 of~~

~~ineffectiveness income recognized prior to 2017 for these swaps was reclassified to~~ ~~Accumulated deficit~~ ~~from~~ ~~Accumulated other comprehensive income~~ ~~effective January 1, 2017.~~

~~Included in~~ ~~Compensation-related expense~~ for the quarter and nine months ended September 30, 2016 is $2.7 million previously classified as a separation of service charge related to the July 2016 resignation of the Company’s former chief executive officer (“CEO”).

Basic net income (loss) 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 average number of shares of common stock outstanding, calculated excluding unvested stock awards. Participating securities include unvested equity awards that contain non-forfeitable rights to dividends prior to vesting.

Diluted net income (loss) per common share is computed by dividing the numerator used to compute basic net income (loss) per common share by the denominator used to compute basic net income (loss) 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 (loss) 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 (loss) per common share were as follows for the indicated periods (dollars in thousands, except per share amounts):

Agency Securities are considered to have limited, if any, credit risk because the timely payment of principal and interest is guaranteed by Fannie Mae and Freddie Mac, which are federally chartered corporations, or Ginnie Mae, which is an agency of the federal government. 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.~~guaranteed. The maturity of ~~Residential mortgage investments~~Agency Securities 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~~289 months.

~~Fixed-rate investments consist of residential mortgage loans and~~Capstead’s ARM 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 London interbank offered rate (“LIBOR”) or the one-year Constant Maturity U.S. Treasury Note Rate (“CMT”), (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 ~~September 30, 2017,~~March 31, 2021, the average months to roll for the Company’s ~~$6.93~~$2.97 billion (amortized cost basis) in current-reset ARM investments was ~~6.5~~approximately seven months while the average months to roll for

the Company’s ~~$6.58~~$4.37 billion (amortized cost basis) in longer-to-reset ARM investments was ~~42.9~~approximately 55 months.

The Company did 0t sell any securities during the quarter ended March 31, 2021. In March 2020, the Company sold available-for-sale securities using the specific identification method for proceeds totaling $2.56 billion recognizing 0 gross realized gains and gross realized losses totaling $67.8 million.

Capstead pledges its Residential mortgage investments as collateral for secured borrowings primarily in the form of repurchase arrangements with commercial banks and other financial ~~institutions (collectively referred to as “counterparties” or “lending counterparties”).~~institutions. 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 financings. 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.

In August 2015 the Company began supplementing its borrowings under repurchase arrangements with advances from the Federal Home Loan Bank (“FHLB”) of Cincinnati. FHLB advances differ from repurchase arrangements in that Capstead pledged collateral to the bank to secure each such advance rather than transferring ownership of the pledged collateral to the bank and simultaneously agreeing to repurchase the transferred assets at a future date. In January 2016 the FHLB system regulator finalized rules originally proposed in 2014 that generally preclude captive insurers from remaining members beyond February 19, 2017 with transition rules that require outstanding advances to be repaid upon maturity or by that date. In response to this action, the Company repaid all outstanding FHLB advances by November 2016 and all of the FHLB stock held by the Company in connection with advance activity was redeemed by December 31, 2016.

The terms and conditions of secured borrowings are negotiated on a transaction-by-transaction basis when each such borrowing is initiated or renewed. 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 are generally fixed based on prevailing rates corresponding to the terms of the borrowings. Interest may be paid monthly or at the termination of a borrowing at which time the

Company may enter into a new borrowing at prevailing haircuts and rates with the same lending counterparty or repay that counterparty and negotiate financing with a different lending counterparty. None of the Company’s lending counterparties are obligated to renew or otherwise enter into new borrowings at the conclusion of existing borrowings. In response to declines in fair value of pledged securities due to changes in market conditions or the publishing of monthly security pay-down factors, lending counterparties 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.

NOTE 6 — USE OF DERIVATIVES, OFFSETTING DISCLOSURES AND CHANGES IN OTHER COMPREHENSIVE INCOME BY COMPONENT

In addition to entering into longer-maturity secured borrowings when available at attractive rates and terms, Capstead attempts to mitigate exposure to higher interest rates by entering into one- and three-month LIBOR-indexed, pay-fixed, receive-variable, interest rate swap agreements. These Derivatives are designated as cash flow hedgesCapstead’s portfolio of derivative financial instruments (“Derivatives”) hedge the variability of the underlying benchmark interest rate of current and forecasted 30- to 90-day secured borrowings. ~~This~~The Company attempts to mitigate exposure to higher interest rates primarily by entering into SOFR- and OIS-indexed, pay-fixed, receive-variable, interest rate swap agreements for terms between eighteen months and three years. From an economic perspective, 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 ~~designated~~ borrowings, leaving primarily 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 any measured hedge ineffectiveness.rate. 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 ~~and nine months~~ ended ~~September 30, 2017~~March 31, 2021, Capstead entered into swap agreements with notional amounts ~~of $650~~totaling $250 million and $3.00 billion requiring fixed-rate interest payments each averaging 1.58% for two and three-year periods commencing on various dates between January and September 2017.

Unsecured borrowings consist of 30-year junior subordinated notes issued in 2005 and 2006 and maturing in 2035 and 2036, for a total face amount of $100 million. ~~Note balances~~ The notes are currently redeemable, in whole or in part, without penalty, at the Company’s option. Balances net of deferred issuance costs, and related weighted average interest rates as of the indicated dates (calculated including issuance cost amortization and adjusted for effects of related Derivatives held as cash flow hedges) were as follows (dollars in thousands):

~~During the quarter and nine months ended September 30, 2017, Capstead issued an additional 1.7 million and 2.1 million shares~~The fair value of its 7.50% Series E Cumulative Redeemable Preferred Stock through an at-the-market continuous offering program at average prices of $24.79 and $24.77, net of underwriting fees and other costs, for net proceeds of $42.1 million and $51.9 million, respectively. No additional preferred shares were issued subsequent to quarter-end through November 3, 2017.

~~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. ~~With the exception of the fair value of lending counterparty investments, all~~All fair values were determined using Level 2 Inputs in accordance with ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820). Lending counterparty investments are nonmarketable securities classified as assets for which Level 3 Inputs are used to determine fair value. These assets are considered strategic investments that are carried at cost and periodically valued and evaluated for impairment. No impairment charges have been recorded relative to these investments and the Company’s cost basis is deemed to approximate fair value.

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 the Company considers recent trading activity for similar investments and pricing levels indicated by lenders in connection with designating collateral for secured borrowings, provided such pricing levels are considered indicative of actual market clearing transactions. In determining fair value estimates for Secured borrowings with initial terms of greater than 120 days, 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~~ these borrowings. The Company ~~currently~~ bases fair value for Unsecured borrowings on discounted cash flows using Company estimates for market yields. Excluded from these disclosures are financial instruments for which 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~~derivative counterparties, receivables, payables and secured borrowings with initial terms of 120 days or less. See NOTE 6 for information relative to the valuation of interest rate swap agreements.

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.-17-

From a credit risk perspective, federal government support for Fannie Mae and Freddie Mac helps ensure that fluctuations in value are due to interest rate changes and are not due to credit risk associated with these ~~securities will be limited. Given that (a) any existing~~securities. The unrealized losses on ~~mortgage securities held~~the Company’s investment in ARM Agency Securities were caused by interest rate changes, and the contractual cash flows of those investments are guaranteed by an agency of the U.S. government. The Company ~~are~~does not ~~attributable~~intend to ~~credit risk~~sell the investments as of March 31, 2021 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 not more likely than not that the Company will ~~not~~ be required to sell ~~any~~the investments before recovery of ~~its investments given the resiliency of the financing market for Agency Securities, none of these investments were considered other-than-temporarily impaired at September 30, 2017.~~their amortized cost bases.

The compensation committee of Capstead’s board of directors (the “Committee”) is responsible for establishing, implementing, and monitoring the Company’s compensation programs and practices. Incentive compensation programs adopted by the Committee for key executives are largely nondiscretionary, formulaic and target-based, utilizing multiple pre-established performance goals (referred to as “metrics”) and defined threshold, target and maximum award amounts determined by reference to established percentages of base salaries. Prior to granting awards, the Committee reviews the Company’s programs, implementing any desired changes in performance metrics and the composition of

~~mortgage REIT industry peer groups used for relative performance metric measurement purposes, as well as establishing each executive’s targeted award opportunity. Equity-based~~All equity-based awards and other long-term incentive awards are made pursuant to the Company’s Amended and Restated 2014 Flexible Incentive Plan that was approved by stockholders in May 2014. At ~~September 30, 2017,~~March 31, 2021, this plan had ~~3,684,662~~1,878,295 shares of common stock remaining available for future issuances.

Under the provisions of Capstead’s annual incentive compensation program, participating executives have overall target award opportunities ranging from 75% to 125% of base salary. Awards are earned based on (a) relative and absolute economic return (change in book value per share of common stock plus common stock dividends divided by beginning book value per share), (b) relative operating cost efficiency (operating expenses divided by ~~Unsecured borrowings~~ ~~and~~ ~~Stockholders’ equity~~), and (c) attainment of individual goals and objectives. Each performance metric is assigned a weighting and performance relative to each metric is calculated separately. No awards can be earned for performance below defined threshold return levels and awards are capped for performance above defined maximum return levels. Included in ~~Accounts payable and accrued expenses~~ at September 30, 2017 are annual incentive compensation accruals for participating executives, together with discretionary accruals for all other employees, totaling $694,000. The Company recognized $(124,000) and $694,000 in ~~Compensation-related expense~~ related to 2017 annual incentive compensation for all employees for the quarter and nine months ended September 30, 2017, respectively. An adjustment to the annual incentive compensation accrual related to finalizing 2016 program results reduced ~~Compensation-related expense~~ ~~during the quarter ended March 31, 2017 by $938,000.~~

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. ~~Included in~~ ~~Accounts payable and accrued expenses~~ ~~are third quarter 2017 DERs distribution amounts totaling $100,000 that were paid in October 2017. Recognized in~~ ~~Compensation-related expense~~ ~~are $100,000 and $320,000 related to the DERs program for the quarter and nine months ended September 30, 2017, respectively.~~

In January 2017 the Committee adjusted the annual incentive compensation program for 2017 to lower the absolute return threshold and target performance levels to reflect current market conditions. In addition, the Committee re-authorized the DERs program with the same terms and conditions, with adjustments made to the amount of individual grants in recognition of current executive responsibilities.

Long-term Equity-based Awards – Performance-based ~~RSUs~~Restricted Stock Units (“RSUs”)

~~Capstead’s performance-based long-term incentive compensation program for key executives provides~~RSU activity and related information for the ~~grant~~quarter ended March 31, 2021 is summarized below:

During the quarters ended March 31, 2021 and 2020, the Company recognized in Compensation-related expense $139,000 and $270,000, respectively, related to RSU awards. Unrecognized estimated compensation expense for these awards totaled $2.5 million at March 31, 2021, to be expensed over a weighted average period of ~~performance-based RSUs that are convertible into shares of common stock following three-year performance periods, contingent upon whether, and to what extent, defined performance~~1.6 years (assumes estimated attainment levels ~~established~~ for ~~certain relative and absolute return~~the related performance metrics are met or exceeded. The relative return metrics measure the Company’s performance on the basis of relative economic return and relative total stockholder return (change in stock price plus reinvested dividends)will be met). The absolute economic return metric measures performance against defined performance 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 threshold level of performance is met, to two shares per unit if the related maximum level of performance is met or exceeded, adjusted for the weighting assigned to the metric. If a metric’s threshold performance level is

~~not met, no shares are issuable under that metric.~~ Dividends accrue from the date of grant and will be paid in cash to the extent the units convert into shares of common stock following completion of the related performance periods.

~~Pursuant to this program, in January 2017, February 2016, January 2015 and December 2013~~ If these shares do not vest, the Committee granted 148,894, 269,354, 247,512 and 242,505 RSUs with three-year performance periods ending December 31, 2019, 2018, 2017 and 2016, respectively. Initial grant date fair values developed for compensation cost purposes of $10.52, $8.03, $8.83 and $12.45 were assigned to the units of each grant, respectively. RSUs granted to the Company’s former CEO totaling 99,257 granted in 2016 and 93,058 granted in 2015 were forfeited subsequent to year-end in accordance with the terms of his 2016 separation agreement with the resulting reversal of compensation cost included in earnings in 2016. RSUs granted to a departed executive totaling 37,199 in 2015 and 36,467 in 2013 were forfeited in 2015. The December 2013 RSUs did not meet the criteria for conversion into shares of common stock pursuant to the applicable performance criteria and, accordingly, remaining awards under this grant were forfeited in the first quarter 2017. The Company recognized $73,000 and $696,000 in ~~Compensation-related expense~~related ~~to outstanding RSUs for the quarter and nine months ended September 30, 2017, respectively.~~dividends will be forfeited. Included in Common stock ~~dividend~~dividends payable at ~~September 30, 2017~~March 31, 2021 are estimated dividends payable pertaining to these awards of ~~$339,000.~~$310,000.

Under a performance-based stock award program last utilized in 2012, the Committee granted common stock awards to all employees with staggered three-year vesting periods with vesting subject to the Company generating returns in excess of established return levels. The last awards granted under this program totaling 62,137 shares with a grant date fair value of $11.67 vested in January 2017, together with related deferred dividends.

In January 2017 and February 2016, respectively, the Committee granted three-year service-based stock awards for 74,446 and 67,337 shares of common stock with grant date fair values of $10.41 and $9.32 per share to executives awarded RSUs. Stock awards granted in 2016 to the Company’s former CEO totaling 24,881 shares were forfeited subsequent to year-end in accordance with the terms of his 2016 separation agreement with the resulting reversal of compensation cost included in earnings in 2016. Remaining awards and related deferred dividends are scheduled to vest in January 2020 and February 2019 assuming service conditions are met. ~~Included in~~ ~~Common stock dividend payable~~ ~~at September 30, 2017 are dividends payable pertaining to these awards of $114,000.~~

In January of 2017 and 2016 and December of 2014, respectively, the Committee granted three-year service-based stock awards for 49,416, 61,272 and 37,237 shares of common stock with grant date fair values of $10.41, $7.87 and $12.47 per share to employees not awarded RSUs. These awards vest in January of 2020, 2019 and 2018 assuming service conditions are met. Similar stock awards granted in December 2013 for a total of 35,703 shares of common stock vested January 3, 2017.

As a component of the Company’s director compensation program, directors are granted service-based stock awards annually upon election or re-election to the board of directors that vest approximately one year from issuance. In July 2017, director common stock awards for a total of 41,881 shares granted in July 2016 with a grant date fair value of $10.03 per share vested on July 15, 2017 and new awards, for a total of 41,797 shares, with a grant date fair value of $10.05 per share were granted that will vest on July 25, 2018.

~~Performance-based and service-based~~Restricted stock award activity for the ~~nine months~~quarter ended ~~September 30, 2017~~March 31, 2021 is summarized below:

During the ~~quarter~~quarters ended March 31, 2021 and ~~nine months ended September 30, 2017,~~2020, the Company recognized in Compensation-related expense $~~220,000~~410,000 and ~~$660,000,~~$433,000, respectively, related to amortization of the grant date fair value of employee stock awards. In addition, during the quarters ended March 31, 2021 and 2020, the Company recognized in Other general and administrative expense ~~$106,000~~ $158,000 and ~~$316,000~~$131,000, respectively, related to amortization of the grant date fair value of director stock ~~awards during the quarter and nine months ended September 30, 2017, respectively.~~awards. Unrecognized compensation expense for unvested stock awards for ~~all~~ employees and directors totaled ~~$1.8~~$3.3 million as of ~~September 30, 2017,~~March 31, 2021, to be expensed over a weighted average period of ~~1.4~~1.5 years.

Service-based stock awards issued to ~~directors~~non-executive employees and to ~~employees not awarded RSUs~~directors receive dividends on a current basis without risk of forfeiture if the related awards do not vest. Stock awards issued to executives ~~awarded RSUs~~ defer the payment of dividends accruing between the grant dates and the end of related service periods. If these awards do not vest, the related accrued dividends will be forfeited.

~~At September 30, 2017 option awards for 30,000 shares of common~~ Included in Common stock ~~were outstanding with a weighted average strike price of $12.28. These awards~~dividend payable at March 31, 2021 are ~~currently exercisable, have~~ no aggregate intrinsic value and have a weighted average remaining contractual term of 1.3 years. No option award activity occurred during the quarter and nine months ended September 30, 2017. All outstanding option awards were granted priorestimated dividends payable pertaining to ~~2010, have ten-year contractual terms and were issued with strike prices equal to the closing market price of Capstead’s common stock on the dates of grant. The fair value of~~ these awards ~~was estimated at that time using a Black-Scholes option pricing model and was expensed over the related vesting periods.~~ totaling $436,000.

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. The Company also 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 quarter and nine months ended September 30, 2017, the Company recognized in ~~Compensation-related expense~~ ~~$31,000 and $119,000 related to contributions to these plans, respectively.~~

Capstead operates as a self-managed REIT earning income from investing in a leveraged portfolio of residential mortgage pass-through securities primarily consisting ~~almost exclusively~~ of relatively short-duration ARM Agency Securities, which reset to more current interest rates within a relatively short period of time and are considered to have limited, if any, credit risk. ~~See NOTE 1 to the consolidated financial statements (included under Item 1 of this report) for defined terms used in this discussion and analysis.~~ By investing in ~~short-duration~~ ARM Agency Securities, the Company is positioned to benefit from future recoveries in financing spreads that typically contract during periods of rising interest rates and to 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~~

Capstead reported for GAAP purposes net income of $19 million, representing $0.15 per diluted common ~~measure~~share for the quarter ended March 31, 2021. The Company reported core earnings of ~~market price sensitivity~~$17 million or $0.13 per diluted common share for the quarter ended March 31, 2021. See “Reconciliation of GAAP and non-GAAP Financial Measures” for more information on core earnings.

GAAP and core earnings benefited from lower secured borrowings rates primarily due to the continued impact of the 150 basis points in reductions in the Fed Funds rate in March 2020 and favorable terms on new interest rate ~~movements. A shorter duration generally indicates less~~swap agreements entered into throughout 2020. These benefits more than offset lower portfolio yields due to lower coupon interest ~~rate risk.~~rates on loans underlying the Company’s ARM Agency Securities and higher investment premium amortization due to higher mortgage prepayment levels as well as changes in lifetime prepayment estimates. Historically low interest rates have led to exceedingly high prepayment speeds across all mortgage products. The Company expects mortgage prepayment rates to peak as the second quarter progresses due in large part to increases in prevailing fixed-rate mortgage rates of nearly 50 basis points since year-end. If longer-term interest rates continue increasing, further declines in prepayments can be expected.

Capstead finances its residential mortgage investments by leveraging its long-term investment capital with secured borrowings consisting ~~primarily~~ of borrowings under repurchase arrangements with commercial banks and other financial institutions. Long-term investment capital ~~totaled $1.37~~declined $6 million during the first quarter of 2021 to $1.00 billion at ~~September 30, 2017,~~March 31, 2021, consisting of ~~$1.02 billion~~$653 million of common and $251 million of preferred stockholders’ equity (recorded amounts), together with ~~$98~~$99 million of unsecured borrowings maturing in 2035 and ~~2036 (recorded amounts). Long-term~~2036.

Capstead’s residential mortgage portfolio decreased $532 million during the first quarter of 2021 to $7.41 billion at March 31, 2021. Secured borrowings decreased $514 million to $6.81 billion as a result of lower portfolio balances. Portfolio leverage (secured borrowings divided by long-term investment ~~capital increased $26 million~~capital) decreased to 6.79 to one at March 31, 2021 from 7.26 to one at December 31, 2020. Management continuously evaluates portfolio leverage levels in ~~2017 as relatively modest declines in common equity capital related to~~light of changes in ~~unrealized~~market conditions.

The near-total shutdown of the U.S. economy in March 2020 due to the COVID-19 pandemic and resulting destabilization of the fixed income markets led to widespread portfolio liquidations and ~~interest rate~~losses for the mortgage REIT industry. During this period of extreme volatility, the Company sold a portion of its portfolio late in March 2020 and reduced its swap ~~gains~~positions in order to ensure it had sufficient flexibility to meet future projected liquidity requirements while maintaining portfolio leverage at comfortable levels. During the crisis, the Company met all of its funding requirements. Intervention by the Federal Reserve beginning in March 2020 in the form of the buying of fixed-rate Agency Securities helped stabilize this key market sector leading to improved pricing levels for fixed-rate Agency Securities. While the Federal Reserve has not purchased ARM Agency Securities specifically, these actions contributed to improved pricing levels for mortgage assets in general and ~~dividends in excess~~stabilized the operating environment for market participants including Capstead.

The Company’s potential liquidity at March 31, 2021 was $540 million and it believes it has ample access to necessary financing through its existing lending counterparties to meet its liquidity needs. See “Utilization of ~~earnings were more than offset by $52 million in preferred equity capital raised through an at-the-market continuous offering program.~~ Long-term Investment Capital and Potential Liquidity” for further discussion.

The Company continues to operate portions of its business continuity plan in response to the pandemic and has not experienced any operational disruption due to its small number of employees who are all able to work remotely. Management will continue to closely monitor the situation and adapt its response as necessary to avoid any operational disruptions.

Book value per share ~~of common stock~~ (total stockholders’ equity, less liquidation preferences for outstanding shares of preferred stock, divided by outstanding shares of common stock) ~~declined 2.7% ($0.29) to $10.56~~as of March 31, 2021 was $6.66 per share, a decrease of ~~which 1.3% ($0.14) was~~$0.10 per share or 1.4% from December 31, 2020 book value of $6.76 per share, primarily reflecting $0.22 in portfolio-related declines in value and $0.05 of declines related to ~~changes in unrealized portfolio and swap gains and 1.4% ($0.15) was returned to stockholders in the form of dividends in excess of earnings.~~

Capstead’s residential mortgage investments portfolio increased $289 million in 2017 to $13.61 billion at September 30, 2017. Secured borrowings increased $322 million to $12.47 billion. Portfolio leverage (secured borrowings divided by long-term investment capital) increased to 9.09 to one at September 30, 2017 from 9.02 to one at December 31, 2016. Management believes current portfolio leverage levels represent an appropriate use of leverage under current market conditions for a portfolio consisting of seasoned, short-duration ARM Agency Securities.

Capstead reported net income of $17 million and $57 million or $0.13 and $0.46 per diluted common share for the quarter and nine months ended September 30, 2017, compared to $16 million and $65 million or $0.13 and $0.56 per diluted common share for the same periods in 2016, respectively. Earnings in 2017 were negatively impacted by high mortgage prepayment levels and higher borrowing costs. Higher borrowing costs werecapital activity, partially offset by higher coupon interest rates on adjustable-rate mortgages underlying the Company’s residential mortgage investments. Earnings also benefited from lower compensation-related accruals. The Company declared a third quarter 2017 common dividend of $0.19 per share that was paid on October 20, 2017 to holders of record on September 30, 2017.

The size and composition of Capstead’s investment portfolio depends on investment strategies being implemented by management, as well as overall market conditions, including the availability of attractively priced investments and suitable financing to leverage the Company’s investment capital. Market conditions are influenced by, among other things, current and future expectations for short-term interest rates, mortgage prepayments and market liquidity.

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.

During the quarter and nine months ended September 30, 2017, Capstead issued 1.7 million and 2.1 million shares of its 7.50% Series E Cumulative Redeemable Preferred Stock through an at-the-market continuous offering program at average prices of $24.79 and $24.77, net of underwriting fees and other costs, for net proceeds of $42 million and $52 million. No additional preferred shares were issued subsequent to quarter-end through November 3, 2017.

On November 1, 2017, Capstead’s board of directors authorized the reinstatement of its previously unused $100 million common stock repurchase program. No shares were repurchased pursuant to this program as of November 3, 2017. The authorization does not obligate the Company to acquire any particular amount of common stock and repurchases under the program and the program itself may be suspended or discontinued at the Company’s discretion without prior notice.

~~The timing, manner, price and amount of any future common and preferred issuances and any common stock repurchases pursuant to these programs will be made~~derivative-related increases in the open market at the Company’s discretion, subject to economic and market conditions, stock price, compliance with federal securities laws and tax regulations as well as blackout periods associated with the dissemination of important Company-specific news.

See NOTE 98 to the consolidated financial statements (included under Item 1 of this report) for additional disclosures regarding fair values of financial instruments held or issued by the Company.

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. The Company’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 portfolio of residential mortgage investments for the quarter ~~and nine months~~ ended ~~September 30, 2017~~March 31, 2021 (dollars in thousands):

Capstead’s investment strategy focuses on managing a portfolio of residential mortgage investments primarily 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 Fannie Mae and Freddie Mac, which are ~~federally chartered corporations,~~government-sponsored enterprises, or Ginnie Mae, which is an agency of the federal government. Federal government support for Fannie Mae and Freddie Mac has largely alleviated market concerns regarding the ability of Fannie Mae and Freddie Mac to fulfill their guarantee obligations.

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 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.

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). The Company’s ARM holdings featured the following characteristics at March 31, 2021 (dollars in thousands):

ARM securities held by Capstead are backed by mortgage loans that ~~generally~~ have coupon interest rates that adjust at least annually to more current interest rates or begin doing so after an initial fixed-rate period. 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. After the initial fixed-rate period, if applicable, the coupon interest rates of mortgage loans underlying the Company’s ARM securities typically adjust either (a) annually based on specified margins over the one-year London interbank offered rate (“LIBOR”) or the one-year Constant Maturity U.S. Treasury Note Rate (“CMT”), (b) semiannually based on specified margins over six-month LIBOR, or (c) 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.

~~Capstead classifies its~~ Fannie Mae and Freddie Mac began accepting ARM ~~securities~~loans based on the Secured Overnight Financing Rate (“SOFR”) in August 2020 and stopped accepting LIBOR-based ARM loans after December 2020 due to the scheduled discontinuation of LIBOR in December 2021. The Company expects to continue investing in Agency ARM Securities backed by a variety of indices including new SOFR-based ARM securities.

Approximately 17% of the Company’s current-reset ARM securities are scheduled to reset in rate within three months, 38% are scheduled to reset in rate between four and six months, 31% are scheduled to reset in rate between seven and 12 months, and 14% are scheduled to reset in rate between 13 and 18 months. The Company’s current-reset ARM securities include $556 million (approximately 19% of the total current-reset ARM securities, with average ~~length~~net WACs of 2.77% and fully-indexed WACs of 1.93%) that will reset in rate for the first time ~~until the loans underlying each security reset to more current rates (“months-to-roll”) (less~~in less than 18 months ~~for “current-reset” ARM securities, and 18 months or greater for “longer-to-reset” ARM securities).

March 31, 2021. After consideration of any applicable initial fixed-rate periods, at ~~September 30, 2017~~March 31, 2021 approximately 90%, 5% and 3% of the Company’s ARM securities were backed by mortgage loans that reset annually, semi-annually and monthly, respectively, while approximately 2% reset every five years. Approximately 86% 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 September 30, 2017 approximately 6%2% of the Company’s ARM securities were backed by interest-only loans, with remaining interest-only payment periods averaging ~~25 months.~~10 months at March 31, 2021. 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 finances its residential mortgage investments by leveraging its long-term investment capital with secured borrowings consisting ~~primarily~~ of borrowings under repurchase arrangements with commercial banks and other financial ~~institutions. Repurchase arrangements entered into by the Company~~institutions that involve the sale and a simultaneous agreement to repurchase the transferred assets at a future date and are accounted for as financings. 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 terms and conditions of secured borrowings are negotiated on a transaction-by-transaction basis when each such borrowing is initiated or renewed. None of the Company’s counterparties are obligated to renew or otherwise enter into new borrowings at the conclusion of existing borrowings. Collateral requirements in excess of amounts borrowed (referred to as “haircuts”) averaged ~~4.5 percent and ranged from 3.0 to 5.0 percent~~4.3% of the fair value of pledged residential mortgage pass-through securities at ~~September 30, 2017.~~March 31, 2021, relatively consistent with prior year. After considering haircuts and related interest receivable on the collateral, as well as interest payable on these borrowings, the Company had ~~$688~~$369 million of capital at risk with its lending counterparties at ~~September 30, 2017.~~March 31, 2021. The Company did not have capital at risk with any single counterparty exceeding ~~4.5%~~5% of total stockholders’ equity at ~~September 30, 2017.~~March 31, 2021.

Secured borrowing rates are ~~generally~~ fixed based on prevailing rates corresponding to the terms of the borrowings. Interest may be paid monthly or at the termination of a borrowing at which time the Company may enter into a new borrowing 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 ~~September 30, 2017~~March 31, 2021, the Company’s secured borrowings totaled ~~$12.47~~$6.81 billion with 2219 counterparties at average rates of ~~1.33%~~0.17%, before the effects of currently-paying interest rate swap agreements. The Company typically uses interest rate swap agreements ~~held as cash flow hedges~~with terms between 18 and ~~1.21% including the effects of these derivatives. To~~36 months and variable rate receipts based on SOFR (previously LIBOR) or Fed Funds to help mitigate exposure to rising short-term interest ~~rates,~~rates. During the first quarter of 2021, the Company ~~uses one- and three-month LIBOR-indexed, pay-fixed, receive-variable interest rate~~increased its swap ~~agreements with two- and three-year interest payment terms supplemented with longer-maturity secured borrowings, when available at attractive rates~~

~~and terms. Excluding $600~~positions by $250 million notional ~~amount of swap agreements that expired October 2, 2017, at~~amount. At quarter-end the Company held ~~$8.25~~$3.22 billion notional amount of ~~portfolio financing-related interest rate swap agreements~~these derivatives at fixed rates averaging 0.06% with contract expirations occurring at various dates through the ~~third~~second quarter of ~~2020~~2024 and a weighted average expiration of 1320 months.

~~After consideration~~Including the effects of ~~all portfolio financing-related swap positions entered into as of quarter-end,~~these derivatives, the Company’s residential mortgage investments and secured borrowings had estimated durations at ~~September 30, 2017~~March 31, 2021 of ~~11¼~~13 months and 8½9¾ months, respectively, for a net duration gap of approximately 2¾3¼ months – see ~~pages 34 and 35 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 its residential mortgage investments by utilizing suitable derivative financial instruments such as interest rate swap agreements, ~~as well as~~Eurodollar futures and longer-maturity secured borrowings, if available at attractive rates and terms.

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. The 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 because secured borrowings generally can be increased or decreased on a daily basis to meet cash flow requirements and otherwise manage capital resources efficiently. Potential liquidity is affected by, among other factors:

~~general conditions in the commercial banking and mortgage finance industries.~~-24-

Capstead’s utilization of its long-term investment capital and its estimated potential liquidity were as follows as of ~~September 30, 2017~~March 31, 2021 in comparison with December 31, ~~2016 (in~~2020 (dollars in thousands):

In order to efficiently manage its liquidity and capital resources, Capstead attempts to maintain sufficient liquidity reserves to fund borrowing and ~~interest rate swap~~derivative 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~~derivative 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.

In response to pricing and ARM supply pressures in the first quarter the Company reduced portfolio leverage by only replacing a portion of portfolio runoff. Future levels of portfolio leverage will be dependent on many factors, including the size and composition of the Company’s investment portfolio (see “Liquidity and Capital Resources”). Management believes current portfolio leverage levels represent an appropriate use of leverage under current market conditions for a portfolio consisting of seasoned, short-duration ARM Agency Securities.

The majority of these loans reset annually based on margins over indices such as 12-month ~~LIBOR, which has increased considerably since late in 2015 with higher short-term interest rates and money market reform.~~

Portfolio yield adjustments for investment premium amortization are primarily driven by mortgage prepayment and investment premium levels. Mortgage prepayment levels are heavily influenced by the availability of mortgage financing at attractive terms and the overall health of the housing markets, as well as seasonal factors. After declining in the first quarter of 2017, average mortgage prepayment levels returned to elevated levels through the end of the third quarter of 2017. This is largely attributable to seasonal factors and a flattening of the yield curve as longer term rates have not increased in tandem with shorter term rates since year-end, allowing for refinancing opportunities in many instances, particularly for borrowers whose loans have recently reset to higher levels. Mortgage prepayments are expected to decline in the coming quarters with the end of the summer selling season and other factors.

Higher unhedged borrowing rates thus far in 2017 are primarily attributable to higher rates negotiated with lending counterparties after the three 25 basis point Federal Funds Rate increases in December 2016, March and June 2017. Fixed swap rates generally increased over the periods presented as older, lower-rate swap agreements expired and newer, higher-rate swaps were entered into in order to provide important balance sheet and future financing spread protection, particularly as it pertains to additions to the longer-to-reset portion of the Company’s ARM securities portfolio. Hedged borrowing rates have benefited from higher short-term LIBOR-based variable-rate swap receipts relative to unhedged borrowing rates.

R~~econciliation~~Reconciliation of GAAP and non-GAAP ~~Financing Spread Disclosures~~Financial Measures

~~Financing spreads on residential mortgage investments differ from total financing spreads, an all-inclusive GAAP measure, that is based on all interest-earning assets and liabilities.~~ Management believes the presentation of core earnings and core earnings per common share, both non-GAAP financial measures, when analyzed in conjunction with the Company’s GAAP operating results, allows investors to more effectively evaluate the Company’s performance and provide investors management’s view of the Company’s economic performance. The Company defines core earnings as GAAP net income (loss) excluding (a) unrealized (gain) loss on derivative instruments, (b) realized loss (gain) on termination of derivative instruments, (c) amortization of unrealized (gain) loss of derivative instruments held at the time of de-designation, and (d) realized loss (gain) on securities. The Company’s presentation of core earnings may not be comparable to similarly-titled measures of other companies, who may use different calculations.

The following reconciles GAAP net income (loss) and net income (loss) per diluted common share to core earnings and core earnings per common share:

Management believes that presenting financing spreads on residential mortgage investments, a non-GAAP financial measure, provides useful information for evaluating the performance of the Company’s portfolio ~~performance.~~as opposed to total financing spreads because the non-GAAP measure speaks specifically to the performance of the Company’s investment portfolio.

~~(b) Calculated excluding a $2.7 million July 2016 separation of service charge recorded in Compensation-related expense.~~

Capstead reported for GAAP purposes net income ~~totaled $17~~of $19 million ~~and $57 million or $0.13 and $0.46~~representing $0.15 per diluted common share for the quarter ~~and nine months~~ ended ~~September 30, 2017, respectively, compared~~March 31, 2021. This compares to ~~$16~~a GAAP net loss of $205 million ~~and $65 million or $0.13 and $0.56~~representing $(2.21) per diluted common share for the same ~~periods~~period in ~~2016. Earnings~~2020. GAAP net income was positively impacted by gains on derivatives of $2 million due to entering into more favorable swap agreements during 2020, as well as $156 million of derivative losses due to declining interest rates and losses on sales of investments of $68 million recognized during the same period in ~~2017~~2020.

Capstead’s core earnings, a non-GAAP financial measure, totaled $17 million or $0.13 per diluted common share for the quarter ended March 31, 2021 compared to core earnings of $20 million or $0.16 per diluted common share for the same period in 2020. Core earnings in the first quarter of 2021 benefited from ~~higher cash yields~~lower borrowing rates while being negatively impacted by ~~high investment premium amortization caused by high~~lower yields on residential mortgage ~~prepayment levels~~investments and ~~higher borrowing costs. Earnings also compared favorably to the prior year due to~~ lower compensation-related accruals, including a $2.7 million separation of service charge ($0.03 per diluted common share) related to the July 2016 resignation of the Company’s former CEO that is recorded in ~~Compensation-related expense~~ ~~in the 2016 periods.~~average portfolio balances.

Interest income on residential mortgage investments was ~~higher~~lower by ~~$7.2 million and $5.4~~$43 million for the quarter ~~and nine months~~ ended ~~September 30, 2017, respectively,~~March 31, 2021 compared to the same ~~periods~~period in ~~2016.~~2020. Lower average yields drove $25 million of the decrease while lower average portfolio balances drove the remaining $18 million.

Yields on residential mortgage investments averaged 1.38% for the quarter ended March 31, 2021, a decrease of 111 basis points compared to the same period in 2020, primarily due to lower coupon interest rates on loans underlying the Company’s ARM Agency Securities that have reset based on lower prevailing interest rates, as well as lower coupons on acquisitions and other changes in portfolio composition. Yields were also negatively impacted by higher premium amortization compared to the same period in 2020 due primarily to higher prepayment rates experienced on the portfolio and changes in prepayment estimates.

Historically low interest rates have led to exceedingly high prepayment speeds across all mortgage products. While ARM securities are priced to incur higher prepayment speeds than fixed rate securities, and fixed rate securities have incurred higher percentage increases than ARM securities over previous levels, the Company’s ARM securities have experienced elevated prepayment speeds ultimately hurting yields on its investments. The Company expects mortgage prepayment rates to peak as the second quarter progresses due in large part to increases ~~are~~in prevailing fixed-rate mortgage rates of nearly 50 basis points since year-end. If longer-term interest rates continue increasing, further declines in prepayments can be expected.

Interest expense on secured borrowings was lower by $41 million for the quarter ended March 31, 2021 compared to the same period in 2020. This decrease is attributable to ~~$7.7 million and $10.4 million in increases related to higher average yields, net of $500,000 and $5.0~~$30 million in decreases related to lower average ~~portfolio balances for the comparative quarter and nine month periods, respectively.~~

Interest expense on secured borrowings was higher by $10.0 million and $18.5 million for the quarter and nine months ended September 30, 2017, respectively, compared to the same periods in 2016. The increases are attributable to $10.3 million and $21.8 million in increases related to higher average borrowing rates ~~net of $300,000~~ and ~~$3.3~~$11 million in decreases related to lower average ~~borrowings for the comparative quarter and nine month periods, respectively.~~

Yields on residential mortgage investments increased 23 and ten basis points, averaging 1.69% and 1.67% during the quarter and nine months ended September 30, 2017, respectively. Cash yields increased 20 and 17 basis points, averaging 2.72% and 2.66% during the quarter and nine months ended September 30, 2017, respectively, largely due to ARM loan coupon interest rates resetting higher to more current rates. Yield adjustments for investment premium amortization declined three basis points during the quarter ended September 30, 2017 to average (103) basis points, while increasing seven basis points during the nine months ended September 30, 2017 to average (99) basis points, primarily as a result of higher mortgage prepayment rates. Mortgage prepayment levels are influenced by the availability of mortgage financing at attractive terms and the health of the housing markets as well as seasonal factors. borrowings.

Secured borrowing rates, ~~adjusted for currently-paying interest rate swap agreements held~~after adjusting for hedging purposes increased 33 and 23 basis points during the quarter and nine months ended September 30, 2017 to average 1.17% and 1.06%. Unhedged borrowing rates accounted for most of the increase, with the remainder attributable to higher interest rate swap costs. Market conditions, including the three 25 basis point increases in the Federal Funds Rate in December 2016, March and June 2017, contributed to higher borrowing rates. Swap costs were impacted by the expiration of older, lower-rate swaps and the addition of new higher-rate swaps, partially offset by higher variable rate swap receipts as a result of higher short-term LIBOR rates. Average fixed-rate swap payments were 108 and 100activities, decreased 152 basis points for the quarter ~~and nine months~~ ended ~~September 30, 2017, respectively,~~March 31, 2021 compared to ~~75 and 72~~the same period in 2020 to average 0.20%. Market conditions contributed to lower borrowing rates, including 150 basis points in reductions to the Federal Funds rate in March 2020. Average fixed-rate swap payment rates were four basis points for the quarter ended March 31, 2021 compared to 162 basis points for the same ~~periods~~period in ~~2016. Variable-rate payment adjustments equated~~2020. This decline was largely due to ~~two and four basis points on average currently-paying~~efforts to reposition the swap portfolio to take advantage of declining market interest rates in 2020. Currently-paying swap notional amounts ~~outstanding for both the quarter and nine months ended September 30, 2017, compared to 18 and 22 basis points, respectively, for the same periods in 2016. Currently-paying swap balances~~ were ~~higher,~~lower, averaging ~~$8.78 billion and $8.40~~$2.99 billion for the quarter ~~and nine months~~ ended ~~September 30, 2017, respectively,~~March 31, 2021 compared to ~~$7.60 billion and $7.54~~$7.10 billion for the same ~~periods~~period in ~~2016.~~2020. Future secured borrowing rates will be dependent on market conditions, including overall levels of market interest rates as well as the availability of longer-maturity borrowings and interest rate swap agreements at attractive rates.

~~Operating~~Total operating costs, ~~(compensation,~~which include Compensation-related expense and Other general and administrative ~~expenses) as a percentage of long-term investment capital is a metric widely used in~~expense, were higher by $150,000 during the mortgage REIT industry as a measure of operating cost efficiency. Capstead, by virtue of its strategy of focusing exclusively on agency-guaranteed ARM securities and being internally managed, is widely recognized as an industry leader in this regard. In

~~comparison to prior year periods, operating costs were impacted by post year-end adjustments to annual incentive compensation accruals of $938,000 and $(655,000) for the three months~~quarter ended March 31, 2017 and 2016, respectively. These adjustments were related to finalizing program results for the years ended December 31, 2016 and 2015, respectively. Operating costs for the third quarter 2017 benefited from adjustments to the Company’s performance-based compensation programs. As further described in NOTE 10 to the accompanying consolidated financial statements (included in Item 1 of this report), the Company’s compensation programs are based in part on relative and absolute economic return performance metrics. ~~Economic return is defined as the change in book value per share of common stock plus common stock dividends declared divided by beginning book value per share.~~

~~Miscellaneous other revenue was lower for the quarter and nine months ended September 30, 2017~~2021 compared to the same ~~periods~~period in 2016 primarily because of the inclusion in 2016 of dividends on Federal Home Loan Bank (“FHLB”) stock held by the Company in connection with FHLB advance activity. The Company repaid its last advance in November 2016 after the FHLB system regulator precluded most captive insurers from continuing to borrow from the FHLBs.2020.

Capstead’s primary sources of funds are secured 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 timing, manner, price and amount of any future common and preferred issuances and any common or preferred stock repurchases will be made in the open market at the Company’s discretion, subject to economic and market conditions, stock price, compliance with federal securities laws and tax regulations as well as blackout periods associated with the dissemination of important Company-specific news.

The Company generally uses its liquidity to pay down secured 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 at ~~September 30, 2017~~March 31, 2021. The discussion accompanying this table and ~~the accompanying discussion~~under “COVID-19 Pandemic” provides insight into the Company’s current liquidity position and perspective on what 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 finances its residential mortgage investments ~~primarily~~ by borrowing under repurchase arrangements, the terms and conditions of which are negotiated on a transaction-by-transaction basis, when each such borrowing is initiated or renewed.

~~None of the Company’s borrowing counterparties are obligated to renew or otherwise enter into new borrowings at the conclusion of existing borrowings.~~ Future borrowings 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. None of the Company’s borrowing counterparties are obligated to renew or otherwise enter into new borrowings at the conclusion of existing borrowings. Secured borrowings totaled ~~$12.47~~$6.81 billion at ~~September 30, 2017,~~March 31, 2021 with ~~all but $33 million~~$6.31 billion maturing within 90 days. Secured borrowings began the year at ~~$12.15~~$7.32 billion and averaged ~~$12.55 billion and $12.38~~$6.88 billion during the quarter ~~and nine months~~ ended ~~September 30, 2017.~~March 31, 2021. Average secured borrowings can differ from period-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 rising short-term interest rates, the Company uses ~~one- and three-month LIBOR-indexed, pay-fixed, receive-variable interest rate swap agreements~~derivatives supplemented with longer-maturity secured borrowings when available at attractive rates and terms. ~~Excluding $600 million notional amount of swap agreements that expired October 2, 2017, at September 30, 2017~~At quarter-end the Company held ~~$8.25~~$3.22 billion notional amount of portfolio financing-related interest rate swap agreements with contract

expirations occurring at various dates through the ~~third~~second quarter of ~~2020~~2024 and a weighted average expiration of 1320 months. ~~Relative to~~The Company also holds swap agreements effectively locking in fixed rates of interest during the 20-year floating rate terms of the Company’s $100 million face amount of unsecured borrowings that mature in ~~2010 the Company entered into forward-starting swap agreements to effectively lock in fixed rates of interest on these borrowings.~~ 2035 and 2036.The Company intends to continue to utilize suitable ~~derivative financial instruments~~derivatives such as interest rate swap agreements or other derivatives and longer-maturity secured borrowings to manage interest rate risk when available at attractive rates and terms.

During the quarter and nine months ended September 30, 2017, Capstead issued an additional 1.7 million and 2.1 million shares of its 7.50% Series E Cumulative Redeemable Preferred Stock through an at-the-market continuous offering program at average prices of $24.79 and $24.77, net of underwriting fees and other costs, for net proceeds of $42 million and $52 million. No additional preferred shares were issued subsequent to quarter-end through November 3, 2017.

The timing, manner, price and amount of any future common and preferred issuances and any common stock repurchases pursuant to these programs will be made in the open market at the Company’s discretion, subject to economic and market conditions, stock price, compliance with federal securities laws and tax regulations as well as blackout periods associated with the dissemination of important Company-specific news.

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 future 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 interest rate swap agreements that typically require interest payments for two-year terms, as well as~~Derivatives and longer-maturity secured borrowings ~~if available at attractive rates and terms. These~~ transactions lengthen the effective duration of the Company’s secured borrowings to more closely match the duration of its portfolio of residential mortgage investments. ~~After consideration~~Including the effects of ~~portfolio financing-related swap positions~~derivatives held to hedge changes in ~~short-term interest~~secured borrowing rates, at ~~September 30, 2017~~March 31, 2021 the Company’s residential mortgage investments and secured borrowings had estimated durations of ~~11¼~~approximately 13 months and 8½9¾ months, respectively, for a net duration gap of approximately 2¾3¼ 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 or other derivatives and longer-maturity secured borrowings, if available at attractive rates and 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, secured borrowings and related ~~derivative financial instruments~~derivatives 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.

This model 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, index floors, and portfolio leverage levels. ~~It is assumed that borrowing rates cannot decline beyond a floor of 0.15%.~~ 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 ~~derivative financial instruments as of the indicated dates,~~derivatives at March 31, 2021 and December 31, 2020, subject to the modeling parameters described above.

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 an investment in Company stock. 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, earnings and financial condition.

~~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~~ ~~secured~~ borrowings, adjusted for the effects of derivative financial instruments 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 ~~secured~~ borrowings not effectively fixed through the use of interest rate swap agreements or similar derivatives 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 can 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 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 ~~secured~~ ~~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.

Periods of illiquidity in the mortgage markets may reduce amounts available under secured borrowing arrangements due to declines in the perceived value of related collateral, which could adversely impact Capstead’s liquidity, financial condition and earnings. Capstead finances its residential mortgage investments by pledging them as collateral under uncommitted secured borrowing arrangements. The amount borrowed is limited to a percentage of the market value of the pledged collateral. The portion of the pledged collateral held by or pledged to the lender in excess of the amount borrowed 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, the Company may be presented with substantial margin calls during such periods. If the Company is unable or unwilling to pledge additional collateral, lenders can liquidate the collateral or seek other remedies, 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 secured 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, which could adversely affect the Company’s liquidity, financial condition and earnings. Capstead enters into secured borrowing 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 secured borrowings on a continuous basis and none of the Company’s counterparties are obligated to enter into new borrowing 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 secured borrowing 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 sell assets under potentially adverse market conditions, which could result in losses. An industry-wide reduction in the availability of secured 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 secured 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 secured borrowing arrangement are negotiated on a transaction-by-transaction basis. Key terms and conditions 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 future secured borrowings. 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 secured borrowings, which could result in losses.

Capstead’s use of borrowings under repurchase arrangements 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 borrowings under repurchase arrangements may give lending counterparties greater rights if the Company seeks bankruptcy protection, exposing the Company to losses.~~ B~~orrowings~~ ~~under repurchase arrangements~~ may qualify for special treatment under the U.S. Bankruptcy Code. If the Company files for bankruptcy, these 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-maturity secured 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 partially offsetting changes in value of its residential mortgage investments as a result of changes in interest rates and 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.

~~Derivative financial instruments held may fail to qualify for hedge accounting introducing potential volatility to Capstead’s earnings.~~ The Company typically qualifies derivatives held as cash flow hedges for accounting purposes in order to record the change in fair value of designated 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.

~~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 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 relatively unorthodox policy initiatives, most notably by inserting itself into the markets as a dominant buyer of U.S. Treasury securities and fixed-rate Agency Securities. This market intervention resulted in a significant expansion of the Federal Reserve’s balance sheet and is often referred to as quantitative easing or QE. The policy goals of the QE initiatives were to support Fannie Mae, Freddie Mac 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. The Federal Reserve ceased increasing its holdings of Treasury and Agency Securities in late 2014, while continuing to replace portfolio runoff through open market purchases.

In general, QE elevated pricing levels for Agency Securities resulting in lower 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.

In October 2017, the Federal Reserve began reducing its existing bond holdings of U.S. Treasury securities and fixed-rate Agency Securities by gradually decreasing the amount of bonds it would purchase to replace portfolio runoff, with the stated goal of reducing the portfolio by $10 billion per month in the fourth quarter of 2017, with such reductions increasing quarterly until reaching $50 billon per month in October 2018. As the buy-side support of such a large market participant is removed, pricing for fixed-rate, and to a lesser extent, ARM Agency Securities could be negatively affected. 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 Fannie Mae and Freddie Mac 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~~ ~~Fannie Mae, Freddie Mac~~ or by Ginnie Mae. 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 secured borrowing 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, ~~Fannie Mae and Freddie Mac~~ ~~incurred substantial losses due to high levels of mortgagor defaults and in 2008 the Federal Housing Finance Agency placed~~ ~~Fannie Mae and Freddie Mac~~ into conservatorship, allowing it to operate them 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.

~~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~~ ~~Fannie Mae and Freddie Mac~~ ~~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~~ ~~Fannie Mae and Freddie Mac~~ 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 ~~Fannie Mae, Freddie Mac~~ ~~and the federal government. A significantly reduced role by the federal government or other changes in the guarantees provided by~~ ~~Fannie Mae, Freddie Mac or~~ Ginnie Mae, 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 short-duration 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 ~~Fannie Mae and Freddie Mac~~, 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 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 secured borrowings which could adversely impact the Company’s liquidity, earnings and book value per common share, as more fully described above.

Legislative and additional regulatory actions could adversely affect the availability and/or terms and conditions of secured borrowings and consequently, the Company’s liquidity, financial condition and earnings. Changes in regulatory capital requirements and other leverage constraints continue to be implemented worldwide. It remains unclear how significant of an impact these changes 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 secured 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 14 employees, Capstead is dependent on the efforts of its key officers and employees, most of whom have significant experience in the mortgage industry. While certain of the Company's named executive officers and 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.

~~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. The Company cannot predict any impact on the value of its securities from adverse legislative or regulatory tax changes.

~~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.

~~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:~~

~~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.

~~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. Beginning in 2018 the threshold for this limitation is reduced to 20%. 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.

~~Distributions payable by Capstead do not qualify for the reduced tax rates applicable to “qualified dividends.”~~ The maximum tax rate applicable to income from non-REIT corporate qualified dividends payable to domestic stockholders that are individuals, trusts or estates is currently 20%. Distributions of ordinary income payable by REITs, however, generally are not eligible for the reduced rates. Although this does not adversely affect the taxation of REITs or distributions payable by REITs, the more favorable rates applicable to regular corporate qualified dividends could cause investors who are individuals, trusts or estates to perceive investments in REITs to be relatively less attractive than investments in the stocks of non-REIT corporations that pay dividends, which could adversely affect the value of REIT stocks.

~~Recognition of excess inclusion income by Capstead could have adverse consequences to its stockholders.~~ If the Company were to modify its investment strategy to invest in Real Estate Mortgage Investment Conduit (“REMIC”) residual interests, or if any of its assets were deemed to be taxable mortgage pools for federal income tax purposes, the Company could recognize “excess inclusion income.” Any such excess inclusion income would be allocated to stockholders in proportion to dividends paid and would not be eligible to be offset by any losses of the stockholders. Further, any such income allocated to stockholders that are tax-exempt entities and not “disqualified organizations,” as described below, would be fully taxable as unrelated business taxable income under Section 512 of the Code. Any stockholders that are foreign persons would be subject to federal income tax at the maximum tax rate and withholding will be required without reduction or exemption pursuant to any otherwise applicable income tax treaties. Finally, to the extent that Capstead stock is owned by disqualified organizations (such as certain government-related entities and tax exempt entities that are not subject to tax on unrelated business income), the Company’s charter provides that, in order to prevent the imposition of a penalty tax on the Company, the Company may redeem or refuse to transfer any of its shares to such disqualified organizations.

~~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.

Capstead may in the future choose to pay dividends in its own stock, in which case stockholders may be required to pay tax in excess of the cash they receive. Capstead may distribute taxable dividends that are payable in part in its stock. In accordance with guidance issued by the Internal Revenue Service, a publicly traded REIT should generally be eligible to treat a distribution of its own stock as fulfilling its REIT distribution requirements if each stockholder is permitted to elect to receive his or her distribution in either cash or stock of the REIT (even where there is a limitation on the percentage of the distribution payable in cash, provided that the limitation is at least 20%), subject to the satisfaction of certain guidelines. If too many stockholders elect to receive cash, each stockholder electing to receive cash generally must receive a portion of his or her distribution in cash (with the balance of the distribution paid in stock). If these and certain other requirements are met, for U.S. federal income tax purposes, the amount of the distribution paid in stock generally will be a taxable distribution in an amount equal to the amount of cash that could have been received instead of stock. Taxable stockholders receiving such dividends would be required to include the full amount of the dividend as ordinary income (or as long-term capital gain to the extent such distribution is properly designated as a capital gain dividend) to the extent of the Company’s current and accumulated earnings and profits for United States federal income tax purposes. As a result, a U.S. holder (as defined in “Federal Income Tax Consequences of Our Status as a REIT”) may be required to pay tax with respect to such dividends in excess of any cash received. If a U.S. holder sells the stock it receives as a dividend in order to pay this tax, it may be subject to transaction fees (e.g., broker fees or transfer agent fees) and the sales proceeds may be less than the amount included in income with respect to the dividend, depending on the market price of its stock at the time of the sale. Furthermore, with respect to Non-U.S. holders (as defined in “Federal Income Tax Consequences of Our Status as a REIT”), the Company may be required to withhold U.S. tax with respect to such dividends, including in respect of all or a portion of such dividend that is payable in stock. In addition, if a significant number of the Company’s stockholders determine to sell shares of its stock in order to pay taxes owed on dividends, it may put downward pressure on the trading price of the Company’s stock. It is uncertain whether and to what extent the Company will pay dividends in cash and its stock.

~~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.

~~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 the Company’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, constitute qualifying real estate interests 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 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:

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:~~

~~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~~.

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:

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 future mortgage prepayments based on 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.

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) income 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~~.

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.~~effective and must monitor ongoing effectiveness on at least a quarterly basis. As long as the hedge relationship remains highly effective, changes in fair value of the derivative are recorded in Accumulated other comprehensive income ~~and reclassified 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). ~~See NOTE 2 to the consolidated financial statements (included under Item 1 of this report) for information regarding the Company’s early-adoption of ASU 2017-12.~~ income.

The Company ~~currently~~ uses derivatives primarily in the form of interest rate swap agreements into hedge ~~relationships accounted for as cash flow hedges in order to hedge~~the variability in borrowing rates ~~due to changes in the underlying benchmark interest rate related to a designated portion of current~~on its secured and ~~anticipated future 30- and 90-day secured borrowings and the 20-year floating-rate periods of~~ unsecured borrowings. ~~Variable-rate~~For derivatives designated as accounting hedges, fixed interest payments ~~to be received on swap agreements~~ and ~~any measured hedge ineffectiveness on~~variable interest ~~rate swap agreements that expired prior to the early-adoption of ASU 2017-12~~receipts are recorded inas an adjustment to interest expense on the related designated borrowings. For derivatives not designated as accounting hedges, fixed interest payments and variable interest receipts are recorded as a component of Other (expense) income. For derivatives initially designated as an ~~offset~~accounting hedge and subsequently de-designated, any unrealized gain or loss included in Accumulated other comprehensive income at the time of de-designation is amortized as an adjustment to interest ~~owed~~expense on the related ~~designated~~ borrowings ~~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.~~over the remaining term of the derivatives. See NOTE 6 to the consolidated financial statements (included under Item 1 of this report) and “Financial Condition – ~~Residential Mortgage Investments”~~Secured Borrowings” for additional information regarding the Company’s current use of derivatives and its related risk management policies.
