NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 – Organization and Business Operations

Invesco Mortgage Capital Inc. (the "Company" or "we") is a Maryland corporation primarily focused on investing in, financing and managing mortgage-backed securities ("MBS") and other mortgage-related assets.

We currently invest in:

•Residential mortgage-backed securities ("RMBS") that are guaranteed by a U.S. government agency such as the Government National Mortgage Association ("Ginnie Mae"), or a federally chartered corporation such as the Federal National Mortgage Association ("Fannie Mae") or the Federal Home Loan Mortgage Corporation ("Freddie Mac") (collectively "Agency RMBS");

•Commercial mortgage-backed securities ("CMBS") that are not guaranteed by a U.S. government agency or a federally chartered corporation ("non-Agency CMBS");

•RMBS that are not guaranteed by a U.S. government agency or a federally chartered corporation ("non-Agency RMBS");

•Commercial mortgage loans; and

•Other real estate-related financing agreements.

We have also historically invested in:

•CMBS that are guaranteed by a U.S. government agency such as Ginnie Mae or a federally chartered corporation such as Fannie Mae or Freddie Mac (collectively "Agency CMBS");

•Credit risk transfer securities that are unsecured obligations issued by government-sponsored enterprises ("GSE CRT"); and

•Residential mortgage loans.

We conduct our business through IAS Operating Partnership L.P. (the "Operating Partnership") and have one operating segment. We are externally managed and advised by Invesco Advisers, Inc. (our "Manager"), a registered investment adviser and an indirect, wholly-owned subsidiary of Invesco Ltd. ("Invesco"), a leading independent global investment management firm.

We elected to be taxed as a real estate investment trust ("REIT") for U.S. federal income tax purposes under the provisions of the Internal Revenue Code of 1986. To maintain our REIT qualification, we are generally required to distribute at least 90% of our REIT taxable income to our stockholders annually. We operate our business in a manner that permits our exclusion from the "Investment Company" definition under the Investment Company Act of 1940, as amended (the "1940 Act").

Our condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") and consolidate the financial statements of the Company and our controlled subsidiaries. All significant intercompany transactions, balances, revenues and expenses are eliminated upon consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for a fair statement of our financial condition and results of operations for the periods presented.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Examples of estimates include, but are not limited to, estimates of the fair values of financial instruments, interest income on mortgage-backed and credit risk transfer securities and allowances for credit losses. Actual results may differ from those estimates.

Significant Accounting Policies

There have been no changes to our accounting policies included in Note 2 to the consolidated financial statements of our Annual Report on Form 10-K for the year ended December 31, 2020.

Accounting Pronouncements Recently Issued

In January 2021, the Financial Accounting Standards Board expanded existing accounting guidance for evaluating the effects of reference rate reform on financial reporting. The new guidance expands the temporary optional expedients and exceptions to U.S. GAAP for contract modifications, hedge accounting and other relationships that reference London Interbank Overnight Financing Rate ("LIBOR") to apply to all derivative instruments affected by the market-wide change in the interest rates used for discounting, margining or contract price alignment (commonly referred to as the discounting transition). The guidance can be applied as of January 1, 2020. We are evaluating our contracts that are eligible for modification relief and may apply the elections prospectively as needed. We are currently evaluating what impact the guidance will have on our consolidated financial statements.

Note 4 – Mortgage-Backed and Credit Risk Transfer Securities

During the first half of 2020, we experienced unprecedented market conditions as a result of the COVID-19 pandemic and sold a substantial portion of our MBS and GSE CRT portfolio to generate liquidity and reduce leverage. We resumed investing in Agency RMBS in July 2020.

The following tables summarize our MBS portfolio by asset type as of June 30, 2021 and December 31, 2020.

(1)Period-end weighted average yield is based on amortized cost as of June 30, 2021 and incorporates future prepayment and loss assumptions.

(2)Agency collateralized mortgage obligation ("Agency-CMO") are interest-only securities ("Agency IO").

(3)Non-Agency RMBS is 64.5% fixed rate, 34.5% variable rate, and 1.0% floating rate based on fair value. Coupon payments on variable rate investments are based upon changes in the underlying Hybrid adjustable-rate mortgage ("ARM") loan coupons, while coupon payments on floating rate investments are based upon a spread to a reference index.

(4)Of the total discount in non-Agency RMBS, $2.1 million is non-accretable (calculated using the principal/notional balance) based on estimated future cash flows of the securities.

(5)Non-Agency RMBS includes interest-only securities ("non-Agency IO") which represent 98.2% of principal/notional balance, 47.0% of amortized cost and 30.0% of fair value.

(2)All Agency-CMO are Agency IO.

(3)Non-Agency RMBS is 67.3% fixed rate, 31.8% variable rate and 0.9% floating rate based on fair value. Coupon payments on variable rate investments are based upon changes in the underlying Hybrid ARM loan coupons, while coupon payments on floating rate investments are based upon a spread to a reference index.

(4)Of the total discount in non-Agency RMBS, $2.1 million is non-accretable calculated using the principal/notional balance based on estimated future cash flows of the securities.

(5)Non-Agency RMBS includes non-Agency IO which represent 98.8% of principal/notional balance, 49.3% of amortized cost and 41.5% of fair value.

The following table presents the fair value of our available-for-sale securities and securities accounted for under the fair value option by asset type as of June 30, 2021 and December 31, 2020. We have elected the fair value option for all of our RMBS interest-only securities and our MBS purchased on or after September 1, 2016. As of June 30, 2021 and December 31, 2020, approximately 99% of our MBS are accounted for under the fair value option.

As of December 31, 2020, we had recorded an allowance for credit losses of $1.8 million on a single non-Agency CMBS on our condensed consolidated balance sheet. We recorded an $830,000 and a $1.8 million decrease in the provision for credit losses on our condensed consolidated statement of operations during the three and six months ended June 30, 2021, respectively. As of June 30, 2021, we do not have an allowance for credit losses recorded on our condensed consolidated balance sheet. We did not record any provisions for credit losses during the three and six months ended June 30, 2020. During the three and six months ended June 30, 2020, we recorded impairments of $6.3 million and $85.1 million, respectively, on our condensed consolidated statement of operations because we intended to sell or more likely than not would be required to sell the securities before recovery of amortized cost basis.

In March 2021, we agreed to extend the contractual maturity of our commercial loan investment from February 2021 to February 2022 at the request of the borrower. The borrower continues to make current interest payments on the loan and posted additional cash reserves in connection with the loan modification. The loan had a principal balance of $23.9 million as of June 30, 2021 and December 31, 2020 and a weighted average coupon rate of 8.59% as of June 30, 2021 and 8.65% as of December 31, 2020. We account for this investment using the fair value option.

We have invested in unconsolidated ventures that are managed by an affiliate of our Manager. The unconsolidated ventures invest in our target assets. Refer to Note 14 - "Commitments and Contingencies" for additional details regarding our commitments to these unconsolidated ventures.

Note 6 – Borrowings

We have historically financed the majority of our investment portfolio through repurchase agreements and secured loans. We fully repaid our secured loans during the year ended December 31, 2020. The following tables summarize certain characteristics of our borrowings at June 30, 2021 and December 31, 2020.

Repurchase Agreements

In the first half of 2020, we experienced unprecedented market conditions as a result of the COVID-19 pandemic. We received an unusually high number of margin calls from our repurchase agreement counterparties during March 2020 following significant spread widening in both Agency and non-Agency securities. As a result, we were unable to meet margin calls and were not in compliance with all of the financial covenants of our repurchase agreements as of March 31, 2020. While certain of our repurchase agreement counterparties permitted our repurchase agreements to remain outstanding while we were not in compliance, other counterparties seized and sold securities that we had posted as collateral for our repurchase agreements. As of May 7, 2020, we repaid all of our repurchase agreements that may have been in default. Gains and losses associated with the termination of these repurchase agreements during the three and six months ended June 30, 2020 are reported as net gain (loss) on extinguishment of debt in our condensed consolidated statement of operations.

We resumed financing the purchase of Agency RMBS with repurchase agreements in July 2020. These repurchase agreements generally bear interest at a contractually agreed upon rate and have maturities of approximately one to six months. Repurchase agreements are accounted for as secured borrowings since we maintain effective control of the financed assets. The repurchase agreements are subject to certain financial covenants. We were in compliance with all of these covenants as of June 30, 2021.

Secured Loans

During the year ended December 31, 2020, IAS Services LLC, our former wholly-owned captive insurance subsidiary, fully repaid its outstanding secured loans from the Federal Home Loan Bank of Indianapolis ("FHLBI").

Note 7 - Collateral Positions

The following table summarizes the fair value of collateral that we pledged and held under our repurchase agreements, interest rate swaps, currency forward contracts and to-be-announced securities forward contracts ("TBAs") as of June 30, 2021 and December 31, 2020. Refer to Note 2 - "Summary of Significant Accounting Policies - Fair Value Measurements" of our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 for a description of how we determine fair value. Agency RMBS collateral pledged is included in mortgage-backed securities on our condensed consolidated balance sheets. Cash collateral pledged on centrally cleared interest rate swaps and currency forward contracts is classified as restricted cash on our condensed consolidated balance sheets. Cash collateral pledged on repurchase agreements and TBAs accounted for as derivatives is classified as due from counterparties on our condensed consolidated balance sheets.

Cash collateral held that is not restricted for use is included in cash and cash equivalents on our condensed consolidated balance sheets and the liability to return the collateral is included in collateral held payable. Non-cash collateral held is only recognized if the counterparty defaults or if we sell the pledged collateral. As of June 30, 2021 and December 31, 2020, we did not recognize any non-cash collateral held on our condensed consolidated balance sheets.

Repurchase Agreements

Collateral pledged with our repurchase agreement counterparties is segregated in our books and records. The repurchase agreement counterparties have the right to resell and repledge the collateral posted but have the obligation to return the pledged collateral, or substantially the same collateral if agreed to by us, upon maturity of the repurchase agreement. Under the repurchase agreements, the respective lender retains the contractual right to mark the underlying collateral to fair value. We would be required to provide additional collateral to fund margin calls if the value of pledged assets declined. We intend to maintain a level of liquidity that will enable us to meet margin calls.

Our repurchase agreement collateral pledged ratio (MBS pledged as collateral/amount outstanding) was 105% as of June 30, 2021 (December 31, 2020: 105%).

Interest Rate Swaps

As of June 30, 2021 and December 31, 2020, all of our interest rate swaps were centrally cleared by a registered clearing organization such as the Chicago Mercantile Exchange ("CME") and LCH Limited ("LCH") through a Futures Commission Merchant ("FCM"). We are required to pledge initial margin and daily variation margin for our centrally cleared interest rate swaps that is based on the fair value of our contracts as determined by our FCM. Collateral pledged with our FCM is segregated in our books and records and can be in the form of cash or securities. Daily variation margin for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral and is recorded as gain (loss) on derivative instruments, net in our condensed consolidated statements of operations. Certain of our FCM agreements include cross default provisions.

TBAs and Currency Forward Contracts

Our TBAs and currency forward contracts provide for bilateral collateral pledging based on market value as determined by our counterparties. Collateral pledged with our TBA and currency forward counterparties is segregated in our books and records and can be in the form of cash or securities. Our counterparties have the right to repledge the collateral posted and have the obligation to return the pledged collateral, or substantially the same collateral, if agreed to by us, as the market value of the contracts changes.

Refer to Note 7 - "Collateral Positions" for further information regarding our collateral pledged to and received from our derivative counterparties.

Interest Rate Swaps

Our repurchase agreements are usually settled on a short-term basis ranging from one to six months. At each settlement date, we typically refinance each repurchase agreement at the market interest rate at that time. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposures to interest rate movements. To accomplish these objectives, we primarily use interest rate swaps as part of our interest rate risk management strategy. Under the terms of the majority our interest rate swap contracts, we make fixed-rate payments to a counterparty in exchange for the receipt of variable-rate amounts over the agreed upon term without exchange of the underlying notional amount. To a lesser extent, we also enter into interest rate swap contracts whereby we make floating-rate payments to a counterparty in exchange for the receipt of fixed-rate amounts as part of our overall risk management strategy.

Amounts recorded in accumulated other comprehensive income ("AOCI") before we discontinued cash flow hedge accounting for our interest rate swaps are reclassified to interest expense on repurchase agreements on the condensed

consolidated statements of operations as interest is accrued and paid on the related repurchase agreements over the remaining life of the interest rate swap agreements. We reclassified $5.4 million and $10.8 million as a decrease (June 30, 2020: $4.5 million and $14.6 million as a decrease) to interest expense for the three and six months ended June 30, 2021, respectively. We increased the amount of gains and losses reclassified as a decrease to interest expense during the three and six months ended June 30, 2020 by $2.7 million because it was probable that the original forecasted repurchase agreement transactions would not occur by the end of the originally specified time period. During the next 12 months, we estimate that $21.2 million will be reclassified as a decrease to interest expense, repurchase agreements. As of June 30, 2021, $41.3 million (December 31, 2020: $52.1 million) of unrealized gains on discontinued cash flow hedges, net are still included in accumulated other comprehensive income and will be reclassified as a decrease to interest expense, repurchase agreements over a period of time through December 15, 2023.

As of June 30, 2021 and December 31, 2020, we had interest rate swaps whereby we pay interest at a fixed rate and receive floating interest based on 1-month LIBOR with the following maturities outstanding, excluding interest rate swaps with forward start dates.

As of June 30, 2021, we held $1.3 billion notional amount of interest rate swaps with forward start dates that will receive floating interest based on 1-month LIBOR with a weighted average maturity of 21.2 years and a weighted average fixed pay rate of 1.29%. We did not hold any interest rate swaps with forward start dates as of December 31, 2020.

As of June 30, 2021, we had interest rate swaps whereby we pay floating interest based on 1-month LIBOR and receive interest at a fixed rate with the following maturities outstanding. We did not hold any such interest rate swaps as of December 31, 2020.

Total	1,000,000	0.10	%	0.37	%	2.9

Swaptions and Currency Forward Contracts

We periodically purchase interest rate swaptions to help mitigate the potential impact of increases or decreases in interest rates on the performance of our Agency RMBS portfolio (referred to as "convexity risk"). The interest rate swaptions provide us the option to enter into interest rate swap agreements for a predetermined notional amount, stated term and pay and receive interest rates in the future. The premium paid for interest rate swaptions is reported as a derivative asset in our condensed consolidated balance sheets. The premium is valued at an amount equal to the fair value of the swaption that would have the effect of closing the position adjusted for nonperformance risk, if any. The difference between the premium and the fair value of the swaption is reported in gain (loss) on derivative instruments, net in our condensed consolidated statements of operations. If an interest rate swaption expires unexercised, the loss on the interest rate swaption would equal the premium paid. If we sell or exercise an interest rate swaption, the realized gain or loss on the interest rate swaption would equal the difference between the cash or the fair value of the underlying interest rate swap received and the premium paid.

We use currency forward contracts to help mitigate the potential impact of changes in foreign currency exchange rates on our investments denominated in foreign currencies. We recognize realized and unrealized gains and losses associated with the purchases or sales of currency forward contracts in gain (loss) on derivative instruments, net in our condensed consolidated statements of operations. As of June 30, 2021, we had $18.0 million (December 31, 2020: $33.1 million) of notional amount of currency forward contracts related to an investment in an unconsolidated venture denominated in Euro.

Credit Derivatives

Our GSE CRTs purchased prior to August 24, 2015 were accounted for as hybrid financial instruments consisting of a debt host contract and an embedded credit derivative. Embedded derivatives associated with GSE CRTs were recorded within mortgage-backed and credit risk transfer securities, at fair value, on the condensed consolidated balance sheets.

TBAs

We primarily use TBAs that we do not intend to physically settle on the contractual settlement date as an alternative means of investing in and financing Agency RMBS. The following table summarizes certain characteristics of our TBAs accounted for as derivatives as of June 30, 2021 and December 31, 2020.

Note 9 – Offsetting Assets and Liabilities

Certain of our repurchase agreements and derivative transactions are governed by underlying agreements that generally provide for a right of offset under master netting arrangements (or similar agreements) in the event of default or in the event of bankruptcy of either party to the transactions. Assets and liabilities subject to such arrangements are presented on a gross basis in the condensed consolidated balance sheets.

The following tables present information about the assets and liabilities that are subject to master netting agreements (or similar agreements) and can potentially be offset on our condensed consolidated balance sheets at June 30, 2021 and December 31, 2020. The daily variation margin payment for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral. As of June 30, 2021, our derivative liability of $17.2 million (December 31, 2020: derivative liability of $5.5 million) related to centrally cleared interest rate swaps is not included in the table below as a result of this characterization of daily variation margin.

Cash collateral pledged on our centrally cleared interest rate swaps is settled against the fair value of these swaps and is therefore excluded from the tables above. We held cash collateral on our derivatives of $310,000 and $1.6 million at June 30, 2021 and December 31, 2020, respectively.

(3)The fair value of securities pledged against our borrowings under repurchase agreements was $8.2 billion and $7.6 billion at June 30, 2021 and December 31, 2020, respectively. We pledged cash collateral of $300,000 and $700,000 under repurchase agreements as of June 30, 2021 and December 31, 2020, respectively. We held cash collateral of $1.9 million under repurchase agreements as of December 31, 2020. We did not hold cash collateral under repurchase agreements as of June 30, 2021.

Note 10 – Fair Value of Financial Instruments

A three-level valuation hierarchy exists for disclosure of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect our market assumptions. The three levels are defined as follows:

•Level 1 Inputs – Quoted prices for identical instruments in active markets.

•Level 2 Inputs – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

•Level 3 Inputs – Instruments with primarily unobservable value drivers.

The following tables present our assets and liabilities measured at fair value on a recurring basis.

(2)Investments in unconsolidated ventures are valued using the net asset value ("NAV") as a practical expedient and are not subject to redemption, although investors may sell or transfer their interest at the approval of the general partner of the underlying funds. As of June 30, 2021 and December 31, 2020, the weighted average remaining term of our investments in unconsolidated ventures was 1.2 years and 1.5 years, respectively.

(3)Includes $20.8 million and $23.1 million of a commercial loan as of June 30, 2021 and December 31, 2020, respectively. We value the loan based on a third party appraisal.

•The estimated fair value of repurchase agreements is a Level 3 fair value measurement based on an expected present value technique. This method discounts future estimated cash flows using rates we determined best reflect current market interest rates that would be offered for repurchase agreements with similar characteristics and credit quality.

Note 11 – Related Party Transactions

Our Manager is at all times subject to the supervision and oversight of our Board of Directors and has only such functions and authority as we delegate to it. Under the terms of our management agreement, our Manager and its affiliates provide us with our management team, including our officers and appropriate support personnel. Each of our officers is an employee of our Manager or one of its affiliates. We do not have any employees. Our Manager is not obligated to dedicate any of its employees exclusively to us, nor is our Manager obligated to dedicate any specific portion of time to our business. During the three and six months ended June 30, 2021, we reimbursed our Manager $261,000 and $559,000 (June 30, 2020: $286,000 and $558,000) for costs of support personnel, respectively.

We invested $1.9 million in money market or mutual funds managed by affiliates of our Manager as of December 31, 2020. The investments are reported as cash and cash equivalents on our condensed consolidated balance sheets as they are highly liquid and have original or remaining maturities of three months or less when purchased. We did not have any investments in money market of mutual funds managed by affiliates of our Manager as of June 30, 2021.

Management Fee

Our management fee is equal to 1.50% of our stockholders' equity per annum. For purposes of calculating the management fee, stockholders' equity is calculated as average month-end stockholders' equity for the prior calendar quarter as determined in accordance with U.S. GAAP. Stockholders' equity may exclude one-time events due to changes in U.S. GAAP and certain non-cash items upon approval by a majority of our independent directors.

We do not pay any management fees on our investments in unconsolidated ventures that are managed by an affiliate of our Manager.

Expense Reimbursement

We are required to reimburse our Manager for operating expenses incurred on our behalf, including directors and officers insurance, accounting services, auditing and tax services, filing fees, and miscellaneous general and administrative costs. Our reimbursement obligation is not subject to any dollar limitation.

The following table summarizes the costs incurred on our behalf by our Manager for the three and six months ended June 30, 2021 and 2020.

Note 12 – Stockholders’ Equity

Preferred Stock

On June 16, 2021 we redeemed all issued and outstanding shares of our Series A Preferred Stock for $140.0 million plus accrued and unpaid dividends. The cash redemption price for each share of Series A Preferred Stock was $25.00. The excess of the consideration transferred over carrying value is accounted for as a deemed dividend and resulted in a reduction of $4.7 million in net income (loss) attributable to common stockholders during the three and six months ended June 30, 2021. Prior to redemption, holders of our Series A Preferred Stock were entitled to receive dividends at an annual rate of 7.75% of the liquidation preference of $25.00 per share or $1.9375 per share per annum. Dividends were cumulative and payable quarterly in arrears.

Holders of our Series B Preferred Stock are entitled to receive dividends at an annual rate of 7.75% of the liquidation preference of $25.00 per share or $1.9375 per share per annum until December 27, 2024. After December 27, 2024, holders are entitled to receive dividends at a floating rate equal to three-month LIBOR plus a spread of 5.18% of the $25.00 liquidation preference per annum. Dividends are cumulative and payable quarterly in arrears.

Holders of our Series C Preferred Stock are entitled to receive dividends at an annual rate of 7.50% of the liquidation preference of $25.00 per share or $1.875 per share per annum until September 27, 2027. After September 27, 2027, holders are entitled to receive dividends at a floating rate equal to three-month LIBOR plus a spread of 5.289% of the $25.00 liquidation preference per annum.

Executive Summary

We are a Maryland corporation primarily focused on investing in, financing and managing mortgage-backed securities ("MBS") and other mortgage-related assets. Our objective is to provide attractive risk-adjusted returns to our stockholders, primarily through dividends and secondarily through capital appreciation. To achieve this objective, we currently invest in the following:

•Residential mortgage-backed securities ("RMBS") that are guaranteed by a U.S. government agency such as the Government National Mortgage Association ("Ginnie Mae") or a federally chartered corporation such as the Federal National Mortgage Association ("Fannie Mae") or the Federal Home Loan Mortgage Corporation ("Freddie Mac") (collectively "Agency RMBS");

•Commercial mortgage-backed securities ("CMBS") that are not guaranteed by a U.S. government agency or a federally chartered corporation ("non-Agency CMBS"); 

•RMBS that are not guaranteed by a U.S. government agency or a federally chartered corporation ("non-Agency RMBS");

•To-be-announced securities forward contracts ("TBAs") to purchase Agency RMBS;

•Commercial mortgage loans; and

•Other real estate-related financing arrangements.

We have also historically invested in:

•CMBS that are guaranteed by a U.S. government agency such as Ginnie Mae or a federally chartered corporation such as Freddie Mac or Fannie Mae (collectively "Agency CMBS");

•Credit risk transfer securities that are unsecured obligations issued by government-sponsored enterprises ("GSE CRT"); and

•Residential mortgage loans.

We are externally managed and advised by Invesco Advisers, Inc. (our "Manager"), an indirect wholly-owned subsidiary of Invesco Ltd. ("Invesco").

We have elected to be taxed as a real estate investment trust ("REIT") for U.S. federal income tax purposes under the provisions of the Internal Revenue Code of 1986. To maintain our REIT qualification, we are generally required to distribute at least 90% of our REIT taxable income to our stockholders annually. We operate our business in a manner that permits our exclusion from the definition of "Investment Company" under the 1940 Act.

Market Conditions

Macroeconomic factors that affect our business include interest rate spread premiums, governmental policy initiatives, monetary policy initiatives, residential and commercial real estate prices, credit availability, consumer personal income and spending, corporate earnings, employment conditions, financial conditions and inflation.

Financial conditions eased once again during the second quarter, as equities and most credit sectors continued to react favorably to an uptick in activity as the economy continued to reopen. In contrast, interest rates fell, reflecting the concerns around the potential impact of COVID-19 variants that have begun to emerge. Equities continued to build on their strong start to the year, with the S&P 500 and the NASDAQ gaining 8.2% and 9.5%, respectively. The employment picture continued to improve during the quarter, as gains in nonfarm payrolls averaged 567,000 per month, and the unemployment rate fell slightly from 6.0% to 5.9% at quarter-end. Consumer activity was mixed during the quarter, as consumer confidence measures dipped, spending increased and retail sales numbers were relatively flat. With the rollout of vaccinations continuing, albeit at a slowing pace, we remain cautiously optimistic about near-term gains in economic activity, particularly given the amount of anticipated government stimulus.

The yield curve flattened during the second quarter as inflation fears were offset by concerns that an uptick in COVID-19 cases, exacerbated by more contagious variants, could upend the recovery. The yield on the 10 year Treasury bond fell 27 basis points to 1.47%, while the yield on the 2 year Treasury note rose 9 basis points to 0.25%. While the short end of the yield curve remains pinned close to zero as the Federal Open Market Committee ("FOMC") targets the lower bound, the futures market has begun to price in increases to the Federal Funds rate beginning late next year. The consumer price index ("CPI") increased sharply, ending the second quarter at 5.4%, up from 2.6% at the end of the first quarter, while the CPI excluding food and energy ended the quarter at 4.5%, up from 1.6% last quarter. Commodity prices also rose sharply during the quarter, with West Texas Intermediate ("WTI") crude recording a 24.9% increase and the Commodity Research Bureau ("CRB") commodity index gaining 15.4%. Breakeven rates on inflation-protected Treasuries were little changed during the second quarter, as the inflation

31

rate implied by 2 year U.S. Treasury inflation-protected securities ("TIPS") rose 5 basis points to 2.72%, while the 5 year breakeven rate fell 10 basis points to 2.50%.

CMBS risk premiums contracted in the second quarter largely due to improving health trends together with supportive fiscal and monetary policies. Amid the recent vaccine rollout and progress towards controlling the pandemic, increased economic activity has translated to slowly improving commercial real estate fundamentals. While commercial mortgage loan delinquencies remain elevated across many property types, they have recently been declining overall. The lodging and retail sectors have experienced the highest level of loan delinquencies due to travel restrictions and a sharp slowdown in activity. Office, multi-family and industrial property sectors continue to post relatively lower delinquency levels. Loans secured by office properties have benefited from long-term tenant leases and industrial warehouse properties have benefited from growing online shopping, as online retailers have demanded more space to support their fulfillment process. Despite increased vacancy rates among some multi-family properties located in central business districts, many properties have performed relatively well as renters have been aided by government support and generous forbearance practices.

While residential real estate fundamentals deteriorated significantly at the onset of the pandemic, low mortgage rates and tight housing supply have driven a significant recovery. Demographic trends and changes in housing preferences shaped by the pandemic led to robust demand, especially for single family homes. This strength is reflected in home price appreciation, which has accelerated rapidly over the past year. Meanwhile, credit spreads on residential mortgage backed securities have largely reversed the widening that occurred in March 2020.

Nevertheless, many individual homeowners have been adversely impacted by the economic consequences of the COVID-19 pandemic. The U.S. government has responded by passing a number of fiscal stimulus measures and relief programs for households and businesses directly or indirectly impacted by the virus. Stimulus payments and the provision of borrower relief including forbearance and loan modifications have substantially reduced borrower defaults and loan losses relative to levels that would have likely occurred without these actions.

Agency RMBS sharply underperformed during the second quarter, as consistent demand from the Federal Reserve was more than offset by elevated net supply, reduced demand from commercial banks, persistent prepayment concerns and an increased likelihood that the Federal Reserve’s timeline for reducing asset purchases would be accelerated. Prepayment speeds moderated during the quarter, but remained elevated, and the lower interest rate environment at quarter-end should keep prepayments near historical highs over the coming months. Premiums on specified pool Agency RMBS improved marginally during the quarter, and we expect those premiums to be well supported as 30 year mortgage rates remain near 3%. The dollar roll environment remained a bright spot, as implied financing rates improved through the quarter as Federal Reserve purchase activity continued to support the market. While wider spread levels improve the attractiveness of Agency RMBS and despite persistent Federal Reserve demand, the headwinds that the Agency RMBS sector faced during the second quarter largely remain intact.

As we move into the third quarter, investors are focused on the pace of the recovery, the increase in price pressures, the trajectory of new COVID-19 cases and the timing of the Federal Reserve's taper of asset purchases. Our expectation is that growth in the U.S. will remain robust as the economy continues to reopen over the course of the year, and that the inflation numbers we have seen over the past quarter will prove transitory.

Proposed Changes to LIBOR

In 2017, the U.K. Financial Conduct Authority (the "FCA"), which regulates LIBOR, announced that the FCA will no longer persuade or compel banks to submit rates for the calculation of the LIBOR benchmark after 2021. This announcement indicates that the continuation of LIBOR will not be guaranteed after 2021. The Alternative Reference Rates Committee ("ARRC"), which was convened by the Federal Reserve Board and the New York Fed to help ensure a successful transition from LIBOR, has proposed that the Secured Overnight Financing Rate ("SOFR") is the rate that represents best practice as the alternative to LIBOR for use in derivatives and other financial contracts that are currently indexed to LIBOR. ARRC has proposed a paced market transition plan to SOFR from LIBOR, and organizations are currently working on industry wide and company specific transition plans as it relates to derivatives and cash markets exposed to LIBOR. Further, on March 5, 2021, the FCA announced that December 31, 2021 will be the cessation date for 1-week & 2-month tenors of USD-LIBOR. The FCA also set June 30, 2023 as the cessation date for the other five tenors (overnight, 1-month, 3-month, 6-month and 12-month) of USD-LIBOR. Additionally, this FCA announcement constitutes an index cessation event under the International Swaps and Derivatives Association Inc.’s ("ISDA") IBOR Fallbacks Supplement and the ISDA 2020 IBOR Fallbacks Protocol, as well as the ARRC’s fallback language for non-consumer cash products, giving the market clarity on the spread adjustments to alternative reference rate based fallbacks for all EUR-, CHF-, GBP-, JPY- and USD-LIBOR settings.

On April 6, 2021, New York State ("NYS") put into law legislation to help address challenges surrounding legacy LIBOR contracts that have no effective means to transition away from LIBOR and to incentivize the selection of SOFR-based fallback rates in other contracts. The law applies to existing USD-LIBOR contracts governed by NYS law that use LIBOR as a

32

benchmark and contain no fallback provisions or contain fallback provisions that result in a benchmark replacement that is based in any way on any LIBOR value. For these in scope contracts, the NYS law provides that on and after "LIBOR Replacement Date" (the date that USD-LIBOR ceases to be published or to be representative), USD-LIBOR is replaced by operation of law with the relevant SOFR-based rate plus the spread adjustment recommended for that contract type by the US Federal Reserve or the ARRC, and any LIBOR-based fallback provisions are permanently overridden. Additionally, the law applies to existing USD-LIBOR contracts governed by NYS law that contain fallback provisions that permit or require a party to select a benchmark replacement that is based in any way on any LIBOR value or otherwise in its discretion. For such contracts, the law authorizes and safe harbors the selection by such party of the relevant SOFR-based rate plus the spread adjustment recommended for that contract type by the Federal Reserve or the ARRC to apply on and after the "LIBOR Replacement Date".

SOFR is an overnight rate unlike LIBOR which is a forward-looking term rate, making SOFR an inexact replacement for LIBOR. There is currently no perfect way to create robust, forward-looking, SOFR term rates. Note that the ARRC has announced that they will not recommend a forward-looking SOFR term rate by mid-2021, as previously announced, due to insufficient development of the SOFR derivatives markets. Market participants are still considering how various types of financial instruments and securitization vehicles should react to a discontinuation of LIBOR. It is possible that not all of our assets and liabilities will transition away from LIBOR at the same time or to the same alternative reference rate, in each case increasing the difficulty of hedging. Switching existing financial instruments and hedging transactions from LIBOR to SOFR requires calculations of a spread and there is no assurance that the spread adjustments will avoid negative financial impacts on our portfolio at the time of transition.

We have material contracts that are indexed to LIBOR and are monitoring this activity and evaluating the related risks. However, it is not possible to predict the effect of any of these developments, and any future initiatives to regulate, reform or change the manner of administration of LIBOR could result in adverse consequences to the rate of interest payable and receivable on, market value of and market liquidity for LIBOR-based financial instruments. We do not currently intend to amend our 7.75% Fixed-to-Floating Series B Cumulative Redeemable Preferred Stock or our 7.50% Fixed-to-Floating Series C Cumulative Redeemable Preferred Stock to change the existing USD-LIBOR cessation fallback language. Our Series B and Series C Preferred Stock each become callable at the time the stock begins to pay a USD-LIBOR-based rate. Should we choose to call the Series B or Series C Preferred Stock in order to avoid a dispute over the results of the USD-LIBOR fallbacks for that class, we may be forced to raise additional funds at an unfavorable time.

The Financial Accounting Standards Board has also issued accounting guidance that provides optional expedients and exceptions to contracts, hedging relationships and other transactions impacted by LIBOR transition if certain criteria are met. The guidance can be applied as of January 1, 2020. We are evaluating our contracts that are eligible for modification relief and may apply the elections prospectively as needed. We are currently evaluating what impact the guidance will have on our consolidated financial statements.

Total investment portfolio, including TBAs	10,312,886	9,983,899	1,625,196

(1)TBAs that we do not intend to physically settle on the contractual settlement date are accounted for as derivative financial instruments and recorded on our consolidated balance sheets at net carrying value, which represents the difference between the fair market value and the implied cost basis of the TBAs. Refer to Note 8 "Derivatives and Hedging Activities" in Part I. Item 1 of this report on Form 10-Q.

We sold $9.8 billion and purchased $11.0 billion of Agency RMBS during the six months ended June 30, 2021 primarily to capitalize on a sharp increase in interest rates and lower valuations on investment opportunities early in the year. Purchases were funded with proceeds from the sales, paydowns of securities and by leveraging proceeds from the issuance of common stock.

As of June 30, 2021, our holdings of 30 year fixed-rate Agency RMBS represented approximately 84% of our total investment portfolio, including TBAs, versus 81% as of December 31, 2020 and less than 1% as of June 30, 2020. We sold substantially all of our Agency RMBS portfolio in the first half of 2020 to generate liquidity and reduce leverage. We resumed investing in 30 year fixed-rate Agency RMBS in July 2020 and began investing in TBAs in the third quarter of 2020. Our Agency RMBS holdings as of June 30, 2021 consisted primarily of specified pools with coupon distributions as shown in the table below.

$ in thousands	Fair Value	Percentage
2.0%	3,893,021	45.0	%
2.5%	2,567,396	29.7	%
3.0%	2,182,413	25.3	%
Total Agency RMBS	8,642,830	100.0	%

Our purchases of Agency RMBS have been primarily focused on specified pools with prepayment protection, as low mortgage rates and a robust housing market have increased borrower incentives to prepay their mortgage loans. We seek to mitigate the negative impact of prepayments on our investment portfolio by purchasing specified pools with characteristics that diminish borrower incentive to prepay, such as a lower loan balance, higher loan-to-value ("LTV") ratio, lower FICO score, higher percentage of non-owner occupied loans (investment and vacation properties) and newly originated loans. In addition, we focus a significant amount of purchases in specified pools that have higher geographic concentrations in states that exhibit slower prepayments such as New York, Florida and Texas.

We invest in TBAs as an alternative means of investing in and financing Agency RMBS. As of June 30, 2021, the implied cost basis of TBAs represented approximately 15% of our total investment portfolio versus 18% as of December 31, 2020. As of June 30, 2021, our investments consist of 30 year Agency RMBS TBAs with 2.5% coupons in conventional collateral. We maintain a meaningful allocation to TBAs given attractive implied financing rates in the Agency RMBS TBA

34

dollar roll market. Implied financing rates in the dollar roll market were substantially below those available in the repurchase market due to the magnitude and persistence of the Federal Reserve's MBS purchase program, which began to increase holdings in March of 2020. We expect the purchase program to continue in 2021, as the Federal Reserve views the program as a key component of its stated objectives.

As of June 30, 2021 and December 31, 2020 our holdings of non-Agency CMBS represented approximately 1% of our total investment portfolio, including TBAs, versus 90% as of June 30, 2020. Our non-Agency CMBS portfolio is collateralized by loans secured by various property types located across the United States including office, retail, multifamily, industrial warehouses and hotels. The largest property geographic locations are in California, New York, Texas, Illinois and Florida. Most of our non-Agency CMBS portfolio is comprised of fixed-rate securities that are rated investment grade by a nationally recognized statistical rating organization. All of our non-Agency CMBS are rated single-A (or equivalent) or higher by a nationally recognized statistical rating organization as of June 30, 2021. Further, approximately 72% of non-Agency CMBS are rated double-A (or equivalent) or higher by a nationally recognized statistical rating organization as of June 30, 2021.

As of June 30, 2021 and December 31, 2020, our holdings of non-Agency RMBS represented less than 1% of our total investment portfolio, including TBAs, versus 1% as of June 30, 2020. We historically held non-Agency RMBS securities collateralized by prime and Alt-A loans and invested in re-securitizations of real estate mortgage investment conduit ("Re-REMIC") RMBS and securitizations of reperforming mortgage loans.

We did not hold any GSE CRTs as of June 30, 2021 or December 31, 2020. Our holdings of GSE CRT represented approximately 6% of our total investment portfolio as of June 30, 2020. GSE CRTs are unsecured general obligations of the GSEs that are structured to provide credit protection to the issuer with respect to defaults and other credit events within pools of mortgage loans that collateralize MBS issued and guaranteed by the GSEs.

As of June 30, 2021, we held an investment in one commercial real estate mezzanine loan that is due in 2022 and has a loan-to-value ratio of approximately 78.9%.

As of June 30, 2021, we held investments in two unconsolidated ventures that are managed by an affiliate of our Manager. The unconsolidated ventures invest in our target assets.

Financing and Other Liabilities

We have historically used repurchase agreements to finance the majority of our target assets and expect to continue to use repurchase agreements to finance Agency investments in the future. Repurchase agreements are generally settled on a short-term basis, usually from one to six months, and bear interest at rates that have historically moved in close relationship to LIBOR.

We also used secured loans from the FHLBI to finance a portion of our investment portfolio. We repaid our secured loans during 2020 with proceeds from sales of assets that collateralized the secured loans. We terminated our membership in FHLBI in the third quarter of 2020.

The following table presents the amount of collateralized borrowings outstanding under repurchase agreements and secured loans as of the end of each quarter, the average amount outstanding during the quarter and the maximum balance outstanding during the quarter:

$ in thousands	Collateralized borrowings under repurchase agreements and secured loans
Quarter Ended	Quarter-end balance	Average quarterly balance (1)	Maximum balance (2)
June 30, 2020	740,000	983,599	1,373,296
September 30, 2020	5,243,288	3,373,356	5,243,288
December 31, 2020	7,228,699	6,883,773	7,237,496
March 31, 2021	8,240,887	8,359,010	8,708,686
June 30, 2021	7,851,204	7,945,494	8,004,924

(1)Average quarterly balance for each period is based on month-end balances.

(2)Amount represents the maximum borrowings at month-end during each of the respective periods.

We have committed to invest up to $125.4 million in unconsolidated ventures that are sponsored by an affiliate of our Manager. As of June 30, 2021, $118.7 million of our commitment to these unconsolidated ventures has been called. We are committed to fund $6.7 million in additional capital to fund future investments and cover future expenses should they occur.

35

Hedging Instruments

We enter into interest rate swap agreements that are designed to mitigate the effects of increases in interest rates for a portion of our borrowings. Under these swap agreements, we make fixed interest rate payments and receive floating interest rate payments indexed off of one- or three-month LIBOR. To a lesser extent, we also enter into interest rate swap agreements whereby we make floating interest rate payments indexed off of one- or three-month LIBOR and receive fixed interest rate payments as part of our overall risk management strategy.

We actively manage our swap portfolio by terminating and entering into new swaps as the size and composition of our investment portfolio changes. During the six months ended June 30, 2021, we terminated existing swaps with a notional amount of $500.0 million and entered into new swaps with a notional amount of $1.5 billion as part of our overall risk management strategy. Daily variation margin payment for interest rate swaps is characterized as settlement of the derivative itself rather than collateral and is recorded as a realized gain or loss in our condensed consolidated statement of operations. We realized a net gain of $161.2 million on interest rate swaps during the six months ended June 30, 2021 primarily due to rising interest rates.

We enter into currency forward contracts to help mitigate the potential impact of changes in foreign currency exchange rates on investments denominated in foreign currencies. As of June 30, 2021, we had €14.8 million or $18.0 million (December 31, 2020: €27.8 million or $33.1 million) of notional amount of forward contracts denominated in Euro related to our investment in an unconsolidated venture. During the six months ended June 30, 2021, we settled currency forward contracts of €41.7 million or $49.9 million (June 30, 2020: €41.7 million or $45.8 million) in notional amount and realized a net loss of $552,000 (June 30, 2020: $346,000 net gain).

Capital Activities

In February 2021, we completed a public offering of 27,600,000 shares of common stock at the price of $3.75 per share. Total net proceeds were approximately $103.1 million after deducting offering expenses.

In June 2021, we completed a public offering of 43,125,000 shares of common stock at the price of $3.39 per share. Total net proceeds were approximately $145.9 million after deducting offering expenses.

On June 16, 2021 we redeemed all issued and outstanding shares of our Series A Preferred Stock for $140.0 million plus accrued and unpaid dividends. The cash redemption price for each share of Series A Preferred Stock was $25.00. The excess of the consideration transferred over carrying value is accounted for as a deemed dividend and resulted in a reduction of $4.7 million in net income (loss) attributable to common stockholders during the three and six months ended June 30, 2021.

As of June 30, 2021, we may sell up to 22,060,000 shares of our common stock from time to time in at-the-market or privately negotiated transactions under an equity distribution agreement with a placement agent. We sold 15,500,000 shares under our equity distribution agreement for proceeds of $57.8 million, net of approximately $831,000 in commissions and fees during the six months ended June 30, 2021. We did not sell any shares of common stock under equity distribution agreements during the three months ended June 30, 2021 or three and six months ended June 30, 2020.

For information on dividends declared during the six months ended June 30, 2021 and 2020, see Note 12 - "Stockholders' Equity" of our condensed consolidated financial statements in Part I. Item 1 of this report on Form 10-Q.

During the six months ended June 30, 2021, we did not repurchase any shares of our common stock.

Book Value per Common Share

We calculate book value per common share as follows:

	As of
$ in thousands except per share amounts	June 30, 2021	December 31, 2020
Numerator (adjusted equity):
Total equity	1,373,379	1,367,158

Denominator (number of shares):
Common stock outstanding	289,681	203,222
Book value per common share	3.21	3.86

Our book value per common share decreased 16.8% as of June 30, 2021 compared to December 31, 2020. The increase in interest rate volatility and prepayment speeds, combined with reduced investor demand for prepayment protection and the potential for an earlier than expected taper of MBS purchases from the Federal Reserve resulted in Agency RMBS sharply underperforming interest rate swap hedges during the first half of 2021. In particular, lower coupon 30 year Agency RMBS underperformed given their increased sensitivity to changes in interest rates and expectations of the Federal Reserve’s tapering. Refer to Item 3. "Quantitative and Qualitative Disclosures About Market Risk" for interest rate risk and its impact on fair value.

Interest Income and Average Earning Asset Yields

The table below presents information related to our average earning assets and earning asset yields for the three and six months ended June 30, 2021 and 2020.

	Three Months Ended June 30,				Six Months Ended June 30,
$ in thousands	2021		2020		2021		2020
Average earning assets (1)	8,829,072		1,905,555		9,078,218		9,871,653
Average earning asset yields (2)	1.96	%	6.33	%	1.83	%	4.39	%

(1)Average balances for each period are based on weighted month-end balances.

(2)Average earning asset yields for the period were calculated by dividing interest income, including amortization of premiums and discounts, by average earning assets based on the amortized cost of the investments. All yields are annualized.

Our primary source of income is interest earned on our investment portfolio. We had average earning assets of approximately $8.8 billion for the three months ended June 30, 2021 (June 30, 2020: $1.9 billion) and $9.1 billion for the six months ended June 30, 2021 (June 30, 2020: $9.9 billion). Average earning assets increased for the three months ended June 30, 2021 compared to 2020 as we resumed investing in Agency RMBS during the third quarter of 2020 after selling a substantial portion of our MBS and GSE CRT portfolio in the first half of 2020 to generate liquidity and reduce leverage in response to the financial market disruption caused by the COVID-19 pandemic. Average earning assets decreased for the six months ended June 30, 2021 compared to 2020 primarily due to these sales.

We earned total interest income of $43.2 million and $83.2 million for the three and six months ended June 30, 2021, respectively (June 30, 2020: $30.2 million and $216.9 million). Our interest income includes coupon interest and net premium amortization on MBS and GSE CRTs as well as interest income on commercial and other loans as shown in the table below.

	Three Months Ended June 30,		Six Months Ended June 30,
$ in thousands	2021	2020	2021	2020
Interest Income
MBS and GSE CRT - coupon interest	51,513	26,841	103,003	228,950
MBS and GSE CRT - net premium amortization	(8,879)	2,787	(20,935)	(13,786)
MBS and GSE CRT - interest income	42,634	29,628	82,068	215,164
Commercial and other loans	520	545	1,096	1,708
Total interest income	43,154	30,173	83,164	216,872

MBS and GSE CRT interest income increased $13.0 million for the three months ended June 30, 2021 compared to 2020 primarily due to a $24.7 million increase in coupon interest reflecting higher average earning assets, which was partially offset by a 437 basis point decrease in average earning asset yields. MBS and GSE CRT interest income decreased $133.1 million for the six months ended June 30, 2021 compared to 2020 reflecting lower average earning assets and a 256 basis point decrease in average earning asset yields. Average earning asset yields decreased for the three and six months ended June 30, 2021 compared to 2020 due to changes in portfolio composition. Almost all of our investment portfolio (excluding TBAs) was invested in Agency RMBS as of June 30, 2021. For further details on the composition of our investment portfolio as of June 30, 2021 and 2020, see the discussion under Investment Activities above in this Management's Discussion and Analysis of Financial Condition and Results of Operations.

Interest income on our commercial and other loans decreased $25,000 and $612,000 during the three and six months ended June 30, 2021, respectively, compared to 2020. The decrease for six months ended June 30, 2021 is primarily due to the sale of our loan participation interest in April 2020.

Prepayment Speeds

Our RMBS portfolio (and previously our GSE CRT portfolio) is subject to inherent prepayment risk primarily driven by changes in interest rates, which impacts the amount of premium and discount on the purchase of these securities that is recognized into interest income. Expected future prepayment speeds are estimated on a quarterly basis. Generally, in an environment of falling interest rates, prepayment speeds will increase as homeowners are more likely to prepay their existing mortgage and refinance into a lower borrowing rate. If the actual prepayment speed during the period is faster than estimated, the amortization on securities purchased at a premium to par value will be accelerated, resulting in lower interest income recognized. Conversely, for securities purchased at a discount to par value, interest income will be reduced in periods where prepayment speeds were slower than expected.

39

The following table presents net premium amortization recognized on our MBS and GSE CRT portfolio for the three and six months ended June 30, 2021 and 2020.

	Three Months Ended June 30,		Six Months Ended June 30,
$ in thousands	2021	2020	2021	2020
Agency RMBS	(9,450)	(894)	(21,934)	(21,807)
Agency CMBS	—	(78)	—	(1,744)
Non-Agency CMBS	845	4,473	1,723	9,531
Non-Agency RMBS	(274)	(178)	(724)	2,520
GSE CRT	—	(536)	—	(2,286)
Net (premium amortization) discount accretion	(8,879)	2,787	(20,935)	(13,786)

Net premium amortization increased $11.7 million and $7.1 million for the three and six months ended June 30, 2021, respectively, compared to 2020 primarily due to sales of assets purchased at discounts and the purchase of Agency RMBS at premiums during the second half of 2020 and in 2021.

Our interest income is subject to interest rate risk. Refer to Item 3. "Quantitative and Qualitative Disclosures about Market Risk" for more information relating to interest rate risk and its impact on our operating results.

Interest Expense and Cost of Funds

The table below presents the components of interest expense for the three and six months ended June 30, 2021 and 2020:

	Three Months Ended June 30,		Six Months Ended June 30,
$ in thousands	2021	2020	2021	2020
Interest Expense
Interest expense on repurchase agreement borrowings	2,252	3,233	5,960	92,342
Amortization of net deferred (gain) loss on de-designated interest rate swaps	(5,429)	(4,503)	(10,797)	(14,570)
Repurchase agreements interest expense	(3,177)	(1,270)	(4,837)	77,772
Secured loans	—	1,712	—	8,358
Total interest expense	(3,177)	442	(4,837)	86,130

Our interest expense on repurchase agreement borrowings decreased $1.0 million for the three months ended June 30, 2021 compared to 2020 despite higher average borrowings primarily due to a change in the collateral underlying our repurchase agreements. Our interest expense on repurchase agreement borrowings decreased $86.4 million for the six months ended June 30, 2021 compared to 2020 primarily due to lower average borrowings and a lower average cost of funds reflecting decreases in the Federal Funds interest rate.

Our repurchase agreement interest expense as reported in our condensed consolidated statement of operations includes amortization of net deferred gains and losses on de-designated interest rate swaps as summarized in the table above. Amortization of net deferred gains on de-designated interest rate swaps decreased our total interest expense by $5.4 million and $10.8 million during the three and six months ended June 30, 2021, respectively, and $4.5 million and $14.6 million during the three and six months ended June 30, 2020, respectively. Amounts recorded in AOCI before we discontinued cash flow hedge accounting for our interest rate swaps are reclassified to interest expense on repurchase agreements on the condensed consolidated statements of operations as interest is accrued and paid on the related repurchase agreements over the remaining life of the interest rate swap agreements. We increased the amount of gains and losses reclassified as a decrease to interest expense during the three and six months ended June 30, 2020 by $2.7 million because it was probable that the original forecasted repurchase agreement transactions would not occur by the end of the originally specified time period. During the next twelve months, we estimate that $21.2 million of net deferred gains on de-designated interest rate swaps will be reclassified from other comprehensive income and recorded as a decrease to interest expense.

We repaid our secured loans in the third quarter of 2020 and did not incur interest expense for secured loans during the three and six months ended June 30, 2021. For the three and six months ended June 30, 2020, the weighted average borrowing rate on our secured loans was 0.85% and 1.48%, respectively.

Our total interest expense during the three and six months ended June 30, 2021 decreased $3.6 million and $91.0 million, respectively, compared to 2020 primarily due to decreases of $2.7 million and $94.7 million, respectively, in interest expense on repurchase agreements borrowings and secured loans as discussed above.

The table below presents information related to our borrowings and cost of funds for the three and six months ended June 30, 2021 and 2020:

	Three Months Ended June 30,				Six Months Ended June 30,
$ in thousands	2021		2020		2021		2020
Total average borrowings (1)	7,945,877		981,992		8,145,507		8,756,995
Maximum borrowings during the period (2)	8,004,924		1,373,296		8,708,686		23,132,234
Cost of funds (3)	(0.16)	%	0.18	%	(0.12)	%	1.97	%

(1)Average borrowings for each period are based on weighted month-end balances.

(2)Amount represents the maximum borrowings at month-end during each of the respective periods.

(3)Average cost of funds is calculated by dividing annualized interest expense including amortization of net deferred gain (loss) on de-designated interest rate swaps by our average borrowings.

Total average borrowings increased $7.0 billion in the three months ended June 30, 2021 compared to 2020 because we resumed investing in Agency RMBS in July 2020 and financing purchases with repurchase agreements. Total average borrowings decreased in the six months ended June 30, 2021 compared to 2020 primarily because we repaid repurchase agreements as we sold assets from our MBS and GSE CRT portfolio in the first half of 2020. Average borrowings also decreased because we repaid $1.65 billion of secured loans during 2020. Our average cost of funds decreased 34 and 209 basis points for three and six months ended June 30, 2021, respectively, compared to 2020 primarily due to the factors discussed above.

Net Interest Income

The table below presents the components of net interest income for the three and six months ended June 30, 2021 and 2020:

	Three Months Ended June 30,				Six Months Ended June 30,
$ in thousands	2021		2020		2021		2020
Interest Income
Mortgage-backed and credit risk transfer securities	42,634		29,628		82,068		215,164
Commercial and other loans	520		545		1,096		1,708
Total interest income	43,154		30,173		83,164		216,872
Interest Expense
Interest expense on repurchase agreement borrowings	2,252		3,233		5,960		92,342
Amortization of net deferred (gain) loss on de-designated interest rate swaps	(5,429)		(4,503)		(10,797)		(14,570)
Repurchase agreements interest expense	(3,177)		(1,270)		(4,837)		77,772
Secured loans	—		1,712		—		8,358
Total interest expense	(3,177)		442		(4,837)		86,130
Net interest income	46,331		29,731		88,001		130,742
Net interest rate margin	2.12	%	6.15	%	1.95	%	2.42	%

Our net interest income, which equals interest income less interest expense, totaled $46.3 million and $88.0 million for the three and six months ended June 30, 2021, respectively (June 30, 2020: $29.7 million and $130.7 million). The increase in net interest income for the three months ended June 30, 2021 compared to 2020 was primarily the result of resuming investing in Agency RMBS in July 2020 and financing purchases with repurchase agreement borrowings. The decrease in net interest income for the six months ended June 30, 2021 compared to 2020 was primarily due to the sale of MBS and GSE CRTs in the first half of 2020 as previously discussed.

Our net interest rate margin, which equals the yield on our average assets for the period less the average cost of funds for the period, was 2.12% and 1.95% for the three and six months ended June 30, 2021, respectively (June 30, 2020: 6.15% and 2.42%). The decrease in net interest rate margin for the three and six months ended June 30, 2021 compared to 2020 was primarily due to the change in our portfolio composition, including related repurchase agreements borrowings. For the six

41

months ended June 30, 2021 compared to 2020, net interest rate margin was impacted by decreases in the Federal Funds rate that had a greater impact on our average cost of funds than on our average asset yields. Our cost of funds on all of our borrowings is influenced by changes in short term interest rates, whereas substantially all of the Company’s investments were fixed-rate assets as of June 30, 2021.

Gain (Loss) on Investments, net

The table below summarizes the components of gain (loss) on investments, net for the three and six months ended June 30, 2021 and 2020:

	Three Months Ended June 30,		Six Months Ended June 30,
$ in thousands	2021	2020	2021	2020
Net realized gains (losses) on sale of investments	(118,006)	(404,739)	(234,853)	(409,024)
Impairment of investments the Company intends to sell or more likely than not will be required to sell before recovery of amortized cost basis and other impairments	—	(6,287)	—	(85,121)
Net unrealized gains (losses) on MBS and GSE CRT accounted for under the fair value option	189,804	105,445	(22,108)	(561,427)
Net unrealized gains (losses) on commercial loan and loan participation interest	822	3,023	(2,276)	(2,469)
Realized loss on loan participation interest	—	(3,808)	—	(3,808)
Total gain (loss) on investments, net	72,620	(306,366)	(259,237)	(1,061,849)

During the three and six months ended June 30, 2021, we sold MBS and GSE CRTs and realized net losses of $118.0 million and $234.9 million, respectively (June 30, 2020: net losses of $404.7 million and $409.0 million). The majority of sales during the three and six months ended June 30, 2021 were of lower yielding Agency RMBS to purchase higher yielding Agency RMBS and capitalize on a sharp increase in interest rates and lower valuations on investment opportunities early in the year. We sold securities during the three and six months ended June 30, 2020 to generate liquidity and reduce leverage in response to the financial market disruption caused by the COVID-19 pandemic. A portion of these sales were involuntary liquidations at significantly distressed market prices as certain of our repurchase agreement counterparties seized and sold our securities when we were unable to meet margin calls in March 2020.

We did not record any impairment during the three and six months ended June 30, 2021 because we intended to sell or more likely than not would be required to sell the securities before recovery of amortized cost basis. We recorded $6.3 million and $85.1 million of impairment on non-Agency RMBS and CMBS securities during the three and six months ended June 30, 2020, respectively, because we intended to sell or more likely than not would be required to sell the securities before recovery of amortized cost basis.

We have elected the fair value option for all of our MBS purchased on or after September 1, 2016 and our GSE CRTs purchased on or after August 24, 2015. Before September 1, 2016, we had also elected the fair value option for our non-Agency RMBS interest-only securities. Under the fair value option, changes in fair value are recognized in income in the condensed consolidated statements of operations and are reported as a component of gain (loss) on investments, net. As of June 30, 2021, $8.7 billion (December 31, 2020: $8.1 billion) or 99% (December 31, 2020: 99%) of our MBS and GSE CRT are accounted for under the fair value option.

We recorded net unrealized gains on our MBS and GSE CRT portfolio accounted for under the fair value option of $189.8 million and net unrealized losses of $22.1 million in the three and six months ended June 30, 2021, respectively, compared to net unrealized gains of $105.4 million in the three months ended June 30, 2020 and net unrealized losses of $561.4 million in the six months ended June 30, 2020. Net unrealized gains in three months ended June 30, 2021 largely reflect reversals of unrealized losses upon sale. Net unrealized losses in the six months ended June 30, 2021 reflect wider interest rate spreads on our Agency assets during the first quarter of 2021. Net unrealized losses in the six months ended June 30, 2020 reflect lower interest rates and wider interest rate spreads on our Agency and non-Agency assets.

We recorded an unrealized gain of $822,000 and an unrealized loss of $2.3 million on our commercial loan in the three and six months ended June 30, 2021, respectively, compared to unrealized losses of $785,000 and $2.5 million in the three and six months ended June 30, 2020, respectively. We value our commercial loan based upon a valuation from an independent pricing service.

We recorded a realized loss of $3.8 million on our loan participation interest in the three and six months ended June 30, 2020. We sold our loan participation interest on April 1, 2020.

(Increase) Decrease in Provision for Credit Losses

As of June 30, 2021, $70.9 million of our MBS are classified as available-for-sale and subject to evaluation for credit losses (December 31, 2020: $116.9 million). As of December 31, 2020, we had established a $1.8 million allowance for credit losses on a single non-Agency CMBS based on a comparison of the security's amortized cost basis to discounted expected cash flows. We recorded an $830,000 and a $1.8 million decrease in the provision for credit losses for this security during the three and six months ended June 30, 2021, respectively, because the security fully repaid in June 2021. We did not record any provisions for credit losses the during the three and six months ended June 30, 2020. Refer to Note 4 – "Mortgage-Backed Securities and Credit Risk Transfer Securities" of our condensed consolidated financial statements included in Part I. Item 1 of this Report for additional information on our allowance for credit losses.

Equity in Earnings (Losses) of Unconsolidated Ventures

For the three and six months ended June 30, 2021, we recorded equity in earnings of unconsolidated ventures of $331,000 and $237,000, respectively (June 30, 2020: equity in earnings of $318,000 and $488,000). We recorded equity in earnings for the three and six months ended June 30, 2021 and 2020 primarily due to earnings on the underlying portfolio investments.

Gain (Loss) on Derivative Instruments, net

We record all derivatives on our condensed consolidated balance sheets at fair value. Changes in the fair value of our derivatives are recorded in gain (loss) on derivative instruments, net in our condensed consolidated statements of operations. Net interest paid or received under our interest rate swaps is also recognized in gain (loss) on derivative instruments, net in our condensed consolidated statements of operations.

The tables below summarize our realized and unrealized gain (loss) on derivative instruments, net for the following periods:

During the six months ended June 30, 2021, we terminated existing swaps with a notional amount of $500.0 million and entered into new swaps with a notional amount of $1.5 billion. We realized a net loss of $166.4 million and a net gain of $161.2 million for the three and six months ended June 30, 2021, respectively, on interest rate swaps due to changing interest rates. During the six months ended June 30, 2020, we terminated all of our outstanding interest rate swaps as we repositioned our portfolio in response to unprecedented market conditions associated with the COVID-19 pandemic. Our exposure to interest rate risk decreased as we sold Agency assets and repaid borrowings. We realized a net loss of $904.7 million for the six months ended June 30, 2020 on interest rate swaps primarily due to falling interest rates.

We resumed entering into interest rate swaps in July 2020 as we resumed investing in Agency RMBS and financing our investments with repurchase agreements. As of June 30, 2021, we had $7.9 billion of repurchase agreement borrowings with a weighted average remaining maturity of 52 days. We typically refinance each repurchase agreement at market interest rates upon maturity. We primarily use interest rate swaps to manage our exposure to changing interest rates and add stability to interest rate expense.

As of June 30, 2021 and December 31, 2020, we held the following interest rate swaps whereby we receive interest at a one-month LIBOR rate:

$ in thousands	As of June 30, 2021						As of December 31, 2020
Derivative instrument	Notional Amounts	Weighted Average Fixed Pay Rate		Weighted Average Floating Receive Rate		Average Maturity (Years)	Notional Amounts	Weighted Average Fixed Pay Rate		Weighted Average Floating Receive Rate		Weighted Average Years to Maturity
Interest Rate Swaps (1)	6,300,000	0.41	%	0.09	%	6.2	6,300,000	0.41	%	0.15	%	6.7

(1)Notional amount as of June 30, 2021 excludes $1.3 billion of interest rate swaps with forward start dates.

As of June 30, 2021, we held the following interest rate swaps whereby we pay interest at a one-month LIBOR rate. We did not hold any such interest rate swaps as of December 31, 2020.

$ in thousands	As of June 30, 2021
Derivative instrument	Notional Amounts	Weighted Average Floating Pay Rate		Weighted Average Fixed Receive Rate		Weighted Average Years to Maturity
Interest Rate Swaps	1,000,000	0.10	%	0.37	%	2.9

We use currency forward contracts to help mitigate the potential impact of changes in foreign currency exchange rates. As of June 30, 2021, we had $18.0 million (December 31, 2020: $33.1 million) of notional amount of currency forward contracts related to an investment in an unconsolidated venture denominated in euro.

We primarily use TBAs that we do not intend to physically settle on the contractual settlement date as an alternative means of investing in and financing Agency RMBS. As of June 30, 2021, we had $1.5 billion notional amount of TBAs (December 31, 2020: $1.7 billion). We recorded $17.6 million of realized and unrealized gains and $39.7 million of realized and unrealized losses, net on TBAs during the three and six months ended June 30, 2021, respectively. Realized and unrealized losses in the six months ended June 30, 2021 reflect a sharp increase in mortgage rates during the first quarter of 2021. We did not invest in TBAs during the three and six months ended June 30, 2020.

Realized and Unrealized Credit Derivative Income (Loss), net

The table below summarizes the components of realized and unrealized credit derivative income (loss), net for the three and six months ended June 30, 2020.

	Three Months Ended June 30,	Six Months Ended June 30,
$ in thousands	2020	2020
GSE CRT embedded derivative coupon interest	1,127	5,845
Gain (loss) on settlement of GSE CRT embedded derivatives	(16,414)	(14,131)
Change in fair value of GSE CRT embedded derivatives	12,549	(27,504)
Total realized and unrealized credit derivative income (loss), net	(2,738)	(35,790)

Realized and unrealized credit derivative loss in the three and six months ended June 30, 2020 was driven by a decline in the fair value of our GSE CRT embedded derivatives as asset prices dropped due to spread widening. We did not hold any GSE CRTs during the three and six months ended June 30, 2021.

44

Net Gain (Loss) on Extinguishment of Debt

As discussed in Note 6 - "Borrowings" of our condensed consolidated financial statements include in Part I. Item 1. of this report on Form 10-Q, certain of our counterparties seized and sold securities that we had posted as collateral for our repurchase agreements during the six months ended June 30, 2020. We recorded early termination and legal fees paid to our counterparties that were associated with the termination of these repurchase agreements as a loss on extinguishment of debt and settlements of counterparty claims for less than the principal balance of our repurchase agreements as a gain on extinguishment of debt in our condensed consolidated statement of operations.

Other Investment Income (Loss), net

Our other investment income (loss), net during the three and six months ended June 30, 2020 primarily consisted of quarterly dividends from FHLBI stock. The amount of our dividend income varied based upon the number of shares that we were required to own and the dividend declared per share. FHLBI redeemed our stock at cost during 2020. We terminated our FHLBI membership in the third quarter of 2020.

Expenses

We incurred management fees of $5.5 million and $10.3 million for the three and six months ended June 30, 2021, respectively (June 30, 2020: $9.8 million and $20.7 million). Management fees decreased for the three and six months ended June 30, 2021 compared to the same periods in 2020 due to a lower management fee base. Refer to Note 11 – "Related Party Transactions" of our condensed consolidated financial statements for a discussion of our relationship with our Manager and a description of how our fees are calculated.

Our general and administrative expenses not covered under our management agreement amounted to $2.1 million and $4.1 million for the three and six months ended June 30, 2021, respectively (June 30, 2020: $4.1 million and $7.2 million). General and administrative expenses primarily consist of directors and officers insurance, legal costs, accounting, auditing and tax services, filing fees, and miscellaneous general and administrative costs. General and administrative costs were lower for the three and six months ended June 30, 2021 compared to the same periods in 2020 primarily due to fees paid for third-party legal and advisory services in connection with navigating market disruption associated with the COVID-19 pandemic during the three and six months ended June 30, 2020 totaling $1.5 million and $2.6 million, respectively.

Issuance and Redemption Costs of Redeemed Preferred Stock

On June 16, 2021, we redeemed all issued and outstanding shares of our Series A Preferred Stock. The excess of the consideration transferred over carrying value is accounted for as a deemed dividend and resulted in a reduction of $4.7 million in net income (loss) attributable to common stockholders during the three and six months ended June 30, 2021.

Net Income (Loss) attributable to Common Stockholders

For the three months ended June 30, 2021, our net loss attributable to common stockholders was $88.3 million (June 30, 2020: $299.9 million net loss attributable to common stockholders) or $0.34 basic and diluted net loss per average share available to common stockholders (June 30, 2020: $1.80 basic and diluted net loss per average share available to common stockholders). The change in net income (loss) attributable to common stockholders was primarily due to (i) net gains on investments of $72.6 million in the 2021 period compared to net losses on investments of $306.4 million in the 2020 period; (ii) net losses on derivative instruments of $186.3 million in the 2021 period compared to net losses on derivative instruments of $343,000 in the 2020 period; and (iii) a $16.6 million increase in net interest income.

For the six months ended June 30, 2021 our net loss attributable to common stockholders was $108.7 million (June 30, 2020: $1.9 billion net loss attributable to common stockholders) or $0.45 basic and diluted net loss per average share available to common stockholders (June 30, 2020: $11.91 basic and diluted net loss per average share available to common stockholders). The change in net income (loss) attributable to common stockholders was primarily due to (i) net gains on derivative instruments of $100.7 million in the 2021 period compared to net losses on derivative instruments of $911.1 million in the 2020 period; (ii) net losses on investments of $259.2 million in the 2021 period compared to net losses on investments of $1.1 billion in the 2020 period; (iii) credit derivative net losses of $35.8 million in the 2020 period; and (iv) a $42.7 million decrease in net interest income.

For further information on the changes in net gains (loss) on derivative instruments, net gain (loss) on investments, realized and unrealized credit derivative income (loss), net and net interest income, see preceding discussion under "Gain (Loss) on Derivative Instruments, net," "Gain (Loss) on Investments, net," "Realized and Unrealized Credit Derivative Income (Loss), net," and "Net Interest Income."

Non-GAAP Financial Measures

We use the following non-GAAP financial measures to analyze the Company's operating results and believe these financial measures are useful to investors in assessing our performance as further discussed below:

•earnings available for distribution (and by calculation, earnings available for distribution per common share),

•effective interest income (and by calculation, effective yield),

•effective interest expense (and by calculation, effective cost of funds),

•effective net interest income (and by calculation, effective interest rate margin), and

•economic debt-to-equity ratio. 

The most directly comparable U.S. GAAP measures are:

•net income (loss) attributable to common stockholders (and by calculation, basic earnings (loss) per common share),

•total interest income (and by calculation, earning asset yields),

•total interest expense (and by calculation, cost of funds),

•net interest income (and by calculation, net interest rate margin), and

•debt-to-equity ratio. 

Commencing with the quarter ended June 30, 2021, we changed the title of our non-GAAP measure of core earnings (and by calculation, core earnings per common share) to earnings available for distribution (and by calculation, earnings available for distribution per common share) to clarify what the measure presents. The adjustments made to reconcile net income (loss) attributable to common stockholders to earnings available for distribution are identical to those adjustments that we previously made to determine core earnings.

We adjust our calculations of non-GAAP financial measures for changes in the composition of our investment portfolio where appropriate. We have historically excluded the impact of realized and unrealized gains and losses on GSE CRT embedded derivatives from the calculation of earnings available for distribution. Beginning in 2021, realized and unrealized gains and losses on GSE CRT embedded derivatives no longer impacted the reconciliation of U.S. GAAP net income (loss) attributable to common stockholders to earnings available for distribution because we sold all of our GSE CRTs that were accounted for as hybrid financial instruments during 2020. Additionally, we have historically calculated effective interest income (and by calculation, effective yield) as U.S. GAAP total interest income adjusted for GSE CRT embedded derivative coupon interest that was recorded as realized and unrealized credit derivative income (loss), net. As we no longer earn embedded derivative coupon interest due to the sale of our GSE CRTs during 2020, effective interest income will be equal to U.S. GAAP total interest income beginning in 2021.

We did not present earnings available for distribution for the first half of 2020 or for the year ended December 31, 2020 because earnings available for distribution excluded the material adverse impact of the market disruption caused by the COVID-19 pandemic on our financial condition. In addition, earnings available for distribution for the first half of 2020 and the year ended December 31, 2020 was not indicative of the reduced earnings potential of our current investment portfolio.

The non-GAAP financial measures used by management should be analyzed in conjunction with U.S. GAAP financial measures and should not be considered substitutes for U.S. GAAP financial measures. In addition, the non-GAAP financial measures may not be comparable to similarly titled non-GAAP financial measures of our peer companies.

Earnings Available for Distribution (formerly Core Earnings)

Our business objective is to provide attractive risk-adjusted returns to our stockholders, primarily through dividends and secondarily through capital appreciation. We use earnings available for distribution as a measure of our investment portfolio’s ability to generate income for distribution to common stockholders and to evaluate our progress toward meeting this objective. We calculate earnings available for distribution as U.S. GAAP net income (loss) attributable to common stockholders adjusted for (gain) loss on investments, net; realized (gain) loss on derivative instruments, net; unrealized (gain) loss on derivative instruments, net; TBA dollar roll income; (gain) loss on foreign currency transactions, net; amortization of net deferred (gain) loss on de-designated interest rate swaps; and net (gain) loss on extinguishment of debt.

By excluding the gains and losses discussed above, we believe the presentation of earnings available for distribution provides a consistent measure of operating performance that investors can use to evaluate our results over multiple reporting periods and, to a certain extent, compare to our peer companies. However, because not all of our peer companies use identical

46

operating performance measures, our presentation of earnings available for distribution may not be comparable to other similarly titled measures used by our peer companies. We exclude the impact of gains and losses when calculating earnings available for distribution because (i) when analyzed in conjunction with our U.S. GAAP results, earnings available for distribution provides additional detail of our investment portfolio’s earnings capacity and (ii) gains and losses are not accounted for consistently under U.S. GAAP. Under U.S. GAAP, certain gains and losses are reflected in net income whereas other gains and losses are reflected in other comprehensive income. For example, a portion of our mortgage-backed securities are classified as available-for-sale securities, and we record changes in the valuation of these securities in other comprehensive income on our condensed consolidated balance sheets. We elected the fair value option for our mortgage-backed securities purchased on or after September 1, 2016, and changes in the valuation of these securities are recorded in other income (loss) in our condensed consolidated statements of operations. In addition, certain gains and losses represent one-time events. We may add and have added additional reconciling items to our earnings available for distribution calculation as appropriate.

To maintain our qualification as a REIT, U.S. federal income tax law generally requires that we distribute at least 90% of our REIT taxable income annually, determined without regard to the deduction for dividends paid and excluding net capital gains. We have historically distributed at least 100% of our REIT taxable income. Because we view earnings available for distribution as a consistent measure of our investment portfolio's ability to generate income for distribution to common stockholders, earnings available for distribution is one metric, but not the exclusive metric, that our board of directors uses to determine the amount, if any, and the payment date of dividends on our common stock. However, earnings available for distribution should not be considered as an indication of our taxable income, a guaranty of our ability to pay dividends or as a proxy for the amount of dividends we may pay, as earnings available for distribution excludes certain items that impact our cash needs.

Earnings available for distribution is an incomplete measure of our financial performance and there are other factors that impact the achievement of our business objective. We caution that earnings available for distribution should not be considered as an alternative to net income (determined in accordance with U.S. GAAP), or as an indication of our cash flow from operating activities (determined in accordance with U.S. GAAP), a measure of our liquidity or as an indication of amounts available to fund our cash needs.

(2)A TBA dollar roll is a series of derivative transactions where TBAs with the same specified issuer, term and coupon but different settlement dates are simultaneously bought and sold. The TBA settling in the later month typically prices at a discount to the TBA settling in the earlier month. TBA dollar roll income represents the price differential between the TBA price for current month settlement versus the TBA price for forward month settlement. We include TBA dollar roll income in earnings available for distribution because it is the economic equivalent of interest income on the underlying Agency securities, less an implied financing cost, over the forward settlement period. TBA dollar roll income is a component of gain (loss) on derivative instruments, net on our condensed consolidated statements of operations.

(3)Gain (loss) on foreign currency transactions, net is included in other investment income (loss) net on the condensed consolidated statements of operations.

(4)U.S. GAAP repurchase agreements interest expense on the condensed consolidated statements of operations includes the following components:

Earnings available for distribution during the three and six months ended June 30, 2021 was driven by effective net interest income and TBA dollar roll income. As discussed above, we did not report earnings available for distribution for the three and six months ended June 30, 2020.

Effective Interest Income / Effective Yield / Effective Interest Expense / Effective Cost of Funds / Effective Net Interest Income / Effective Interest Rate Margin

Prior to 2021, we calculated effective interest income (and by calculation, effective yield) as U.S. GAAP total interest income adjusted for GSE CRT embedded derivative coupon interest that was recorded as realized and unrealized credit derivative income (loss), net. We included our GSE CRT embedded derivative coupon interest in effective interest income because GSE CRT coupon interest was not accounted for consistently under U.S. GAAP. We accounted for GSE CRTs purchased prior to August 24, 2015 as hybrid financial instruments, but elected the fair value option for GSE CRTs purchased on or after August 24, 2015. Under U.S. GAAP, coupon interest on GSE CRTs accounted for using the fair value option is recorded as interest income, whereas coupon interest on GSE CRTs accounted for as hybrid financial instruments was recorded as realized and unrealized credit derivative income (loss). We added back GSE CRT embedded derivative coupon interest to our total interest income because we considered GSE CRT embedded derivative coupon interest a current component of our total interest income irrespective of whether we elected the fair value option for the GSE CRT or accounted for the GSE CRT as a hybrid financial instrument.

We calculate effective interest expense (and by calculation, effective cost of funds) as U.S. GAAP total interest expense adjusted for contractual net interest income (expense) on our interest rate swaps that is recorded as gain (loss) on derivative instruments, net and the amortization of net deferred gains (losses) on de-designated interest rate swaps that is recorded as repurchase agreements interest expense. We view our interest rate swaps as an economic hedge against increases in future market interest rates on our floating rate borrowings. We add back the net payments we make on our interest rate swap agreements to our total U.S. GAAP interest expense because we use interest rate swaps to add stability to interest expense. We exclude the amortization of net deferred gains (losses) on de-designated interest rate swaps from our calculation of effective interest expense because we do not consider the amortization a current component of our borrowing costs.

We calculate effective net interest income (and by calculation, effective interest rate margin) as U.S. GAAP net interest income adjusted for contractual net interest income (expense) on our interest rate swaps that is recorded as gain (loss) on derivative instruments, net; amortization of net deferred gains (losses) on de-designated interest rate swaps that is recorded as repurchase agreements interest expense and GSE CRT embedded derivative coupon interest that was recorded as realized and unrealized credit derivative income (loss), net.

We believe the presentation of effective interest income, effective yield, effective interest expense, effective cost of funds, effective net interest income and effective interest rate margin measures, when considered together with U.S. GAAP financial measures, provides information that is useful to investors in understanding our borrowing costs and operating performance.

Our effective interest income increased in the three months ended June 30, 2021 compared to the same period in 2020 primarily due to higher average earning assets, which was partially offset by a decrease in average earning asset yields. Our average earning assets increased to $8.8 billion for the three months ended June 30, 2021 from $1.9 billion for the same period in 2020 because we resumed investing in Agency RMBS during the third quarter of 2020 after selling a substantial portion of our MBS and GSE CRT portfolio in the first half of 2020. Our effective interest income decreased in the six months ended June 30, 2021 compared to the same period in 2020 due to lower average earning assets and yields primarily as a result of our asset sales in the first half of 2020. Our effective yield decreased in the three and six months ended June 30, 2021 compared to the same periods in 2020 due to changes in portfolio composition. Almost all of our investment portfolio (excluding TBAs) was invested in Agency RMBS as of June 30, 2021 compared to less than 1% as of June 30, 2020.

Our effective interest expense increased in the three months ended June 30, 2021 compared to the same period in 2020 due to contractual net interest expense on interest rate swaps of $4.6 million during the three months ended June 30, 2021. We did not incur any contractual net interest expense during the three months ended June 30, 2020. Our effective cost of funds decreased in the three months ended June 30, 2021 compared to the same period in 2020 primarily due to a change in the collateral underlying our repurchase agreements. Additionally, we repaid our secured loans during 2020. Our effective interest expense and effective cost of funds decreased in the six months ended June 30, 2021 compared to the same period in 2020 primarily due to lower average borrowings and a lower average cost of funds reflecting decreases in the Federal Funds interest rate. Lower total interest expense was partially offset by contractual net interest expense on interest rate swaps of $9.1 million during the six months ended June 30, 2021 compared to $11.9 million of contractual net interest income for the same period in 2020.

Economic Debt-to-Equity Ratio

The tables below show the allocation of our stockholders' equity to our target assets, our debt-to-equity ratio, and our economic debt-to-equity ratio as of June 30, 2021 and December 31, 2020. Our debt-to-equity ratio is calculated in accordance with U.S. GAAP and is the ratio of total debt to total stockholders' equity. As of June 30, 2021, approximately 92% of our equity is allocated to Agency RMBS.

We present an economic debt-to-equity ratio, a non-GAAP financial measure of leverage that considers the impact of the off-balance sheet financing of our investments in TBAs that are accounted for as derivative instruments under U.S. GAAP. We include our TBAs at implied cost basis in our measure of leverage because a forward contract to acquire Agency RMBS in the TBA market carries similar risks to Agency RMBS purchased in the cash market and funded with on-balance sheet liabilities. Similarly, a contract for the forward sale of Agency RMBS has substantially the same effect as selling the underlying Agency RMBS and reducing our on-balance sheet funding commitments. We believe that presenting our economic debt-to-equity ratio, when considered together with our U.S. GAAP financial measure of debt-to-equity ratio, provides information that is useful to investors in understanding how management evaluates our at-risk leverage and gives investors a comparable statistic to those other mortgage REITs who also invest in TBAs and present a similar non-GAAP measure of leverage.

Liquidity and Capital Resources

Liquidity is a measurement of our ability to meet potential cash requirements, including ongoing commitments to pay dividends, fund investments, repay borrowings and fund other general business needs. Our primary sources of funds for liquidity consist of the net proceeds from our common and preferred equity offerings, net cash provided by operating activities, proceeds from repurchase agreements and other financing arrangements and future issuances of equity and/or debt securities.

We currently believe that we have sufficient liquidity and capital resources available for the acquisition of additional investments, repayments on borrowings, margin requirements and the payment of cash dividends as required for continued qualification as a REIT. We generally maintain liquidity to pay down borrowings under repurchase arrangements to reduce borrowing costs and otherwise efficiently manage our long-term investment capital. Because the level of these borrowings can be adjusted on a daily basis, the level of cash and cash equivalents carried on our consolidated balance sheets is significantly less important than our potential liquidity available under borrowing arrangements or through the sale of liquid investments. However, there can be no assurance that we will maintain sufficient levels of liquidity to meet any margin calls.

The COVID-19 pandemic-driven disruptions in the real estate, mortgage and financial markets negatively affected our liquidity during the year ended December 31, 2020. Under the terms of our repurchase agreements, our lenders have the contractual right to mark the underlying securities that we post as collateral to fair value as determined in their sole discretion. In addition, our lenders have the contractual right to increase the "haircut", or percentage amount by which collateral value must exceed the amount of borrowings, as market conditions become more volatile. As a result of significant spread widening in both Agency and non-Agency securities in the latter part of the first quarter of 2020, valuations of our portfolio assets declined sharply in a short period of time, leading to an exceptional increase in the frequency and magnitude of margin calls. We sold portfolio assets to generate liquidity, in many cases at significantly distressed market prices. Additionally, our lenders raised required haircuts on our collateral for new repurchase agreements, driving further liquidity needs. These events have led us to seek to avoid financing less liquid assets, such as non-Agency securities, with repurchase agreements.

We held cash, cash equivalents and restricted cash of $488.1 million at June 30, 2021 (June 30, 2020: $271.6 million). Our cash, cash equivalents and restricted cash increased due to normal fluctuations in cash balances related to the timing of

54

principal and interest payments, repayments of debt, and asset purchases and sales. Our operating activities provided net cash of $73.5 million for the six months ended June 30, 2021 (June 30, 2020: $130.6 million).

Our investing activities used net cash of $704.1 million in the six months ended June 30, 2021 compared to net cash provided by investing activities of $18.0 billion in the six months ended June 30, 2020. Our primary source of cash from investing activities for the six months ended June 30, 2021 was proceeds from sales of MBS and GSE CRTs of $9.8 billion (June 30, 2020: $23.1 billion). We also generated $416.5 million from principal payments of MBS and GSE CRTs during the six months ended June 30, 2021 (June 30, 2020: $690.1 million). We invested $11.0 billion in MBS and GSE CRTs during the six months ended June 30, 2021 (June 30, 2020: $5.0 billion). We received cash of $126.3 million to settle derivative contracts in the six months ended June 30, 2021 (June 30, 2020: net cash used of $904.4 million).

Our financing activities provided net cash of $726.1 million for the six months ended June 30, 2021 (June 30, 2020: net cash used by financing activities of $18.2 billion). During the six months ended June 30, 2021, we received net cash from repurchase agreement borrowing of $622.5 million (June 30, 2020: net repayments of $17.5 billion). In addition, we repaid $910.0 million of secured loans from the FHLBI during the six months ended June 30, 2020. We used cash of $140.0 million to redeem our Series A Preferred Stock during the six months ended June 30, 2021. We also used cash of $62.2 million for the six months ended June 30, 2021 to pay dividends (June 30, 2020: $102.6 million). Proceeds from issuance of common stock provided $307.6 million for the six months ended June 30, 2021 (June 30, 2020: $347.1 million).

As of June 30, 2021, the average margin requirement (weighted by borrowing amount), or the haircut, under our repurchase agreements was 4.9% for Agency RMBS. The haircuts ranged from a low of 3% to a high of 5%. Declines in the value of our securities portfolio can trigger margin calls by our lenders under our repurchase agreements. An event of default or termination event may give our counterparties the option to terminate all repurchase transactions outstanding with us and require any amount due from us to the counterparties to be payable immediately.

Effects of Margin Requirements, Leverage and Credit Spreads

Our securities have values that fluctuate according to market conditions and the market value of our securities will decrease as prevailing interest rates or credit spreads increase. When the value of the securities pledged to secure a repurchase loan decreases to the point where the positive difference between the collateral value and the loan amount is less than the haircut, our lenders may issue a "margin call," which means that the lender will require us to pay cash or pledge additional collateral. Under our repurchase facilities, our lenders have full discretion to determine the value of the securities we pledge to them. Most of our lenders will value securities based on recent trades in the market. Lenders also issue margin calls as the published current principal balance factors change on the pool of mortgages underlying the securities pledged as collateral when scheduled and unscheduled paydowns are announced monthly.

We experience margin calls and increased collateral requirements in the ordinary course of our business. In seeking to effectively manage the margin requirements established by our lenders, we maintain a position of cash and unpledged securities. We refer to this position as our liquidity. The level of liquidity we have available to meet margin calls is directly affected by our leverage levels, our haircuts and the price changes on our securities. If interest rates increase as a result of a yield curve shift or for another reason or if credit spreads widen, then the prices of our collateral (and our unpledged assets that constitute our liquidity) will decline, we will experience margin calls, and we will seek to use our liquidity to meet the margin calls. There can be no assurance that we will maintain sufficient levels of liquidity to meet any margin calls or increased collateral requirements. If our haircuts increase, our liquidity will proportionately decrease. In addition, if we increase our borrowings, our liquidity will decrease by the amount of additional haircut on the increased level of indebtedness.

We intend to maintain a level of liquidity in relation to our assets that enables us to meet reasonably anticipated margin calls and increased collateral requirements but that also allows us to be substantially invested in securities. We may misjudge the appropriate amount of our liquidity by maintaining excessive liquidity, which would lower our investment returns, or by maintaining insufficient liquidity, which would force us to liquidate assets into unfavorable market conditions and harm our results of operations and financial condition.

We are subject to financial covenants in connection with our lending, derivatives and other agreements we enter into in the normal course of our business. We intend to operate in a manner which complies with all of our financial covenants. Our lending and derivative agreements provide that we may be declared in default of our obligations if our leverage ratio exceeds certain thresholds and we fail to maintain stockholders’ equity or market value above certain thresholds over specified time periods.

Forward-Looking Statements Regarding Liquidity

As of June 30, 2021, we held $8.2 billion of Agency securities that are financed by repurchase agreements. We also had approximately $516.5 million of unencumbered investments and unrestricted cash of $134.7 million as of June 30, 2021.

Based upon our current portfolio and existing borrowing arrangements, we believe that cash flow from operations, and available borrowing capacity will be sufficient to enable us to meet anticipated short-term (one year or less) liquidity requirements to fund our investment activities, pay fees under our management agreement, fund our required distributions to stockholders and fund other general corporate expenses.

Our ability to meet our long-term (greater than one year) liquidity and capital resource requirements will be subject to obtaining additional debt financing. We may increase our capital resources by obtaining long-term credit facilities or through public or private offerings of equity or debt securities, possibly including classes of preferred stock, common stock, senior or subordinated notes and convertible notes. Such financing will depend on market conditions for capital raises and our ability to invest such offering proceeds. If we are unable to renew, replace or expand our sources of financing on substantially similar terms, it may have an adverse effect on our business and results of operations.

Contractual Obligations

We have entered into an agreement with our Manager under which our Manager is entitled to receive a management fee and the reimbursement of certain operating expenses incurred on our behalf. The management fee is calculated and payable quarterly in arrears in an amount equal to 1.50% of our stockholders’ equity, per annum. Refer to Note 11 - "Related Party Transactions" of our condensed consolidated financial statements for additional information on how our management fee is calculated. Our Manager uses the proceeds from its management fee in part to pay compensation to its officers and personnel who, notwithstanding that certain of those individuals are also our officers, receive no cash compensation directly from us. We are required to reimburse our Manager for operating expenses related to us incurred by our Manager, including certain salary expenses and other expenses relating to legal, accounting, due diligence and other services. Our reimbursement obligation is not subject to any dollar limitation. Refer to Note 11 – "Related Party Transactions" of our condensed consolidated financial statements for details of our reimbursements to our Manager.

As of June 30, 2021, we had the following contractual obligations:

Off-Balance Sheet Arrangements

We have committed to invest up to $125.4 million in unconsolidated ventures that are sponsored by an affiliate of our Manager. As of June 30, 2021, $118.7 million of our commitment to these unconsolidated ventures had been called. We are committed to fund $6.7 million in additional capital to fund future investments and cover future expenses should they occur.

Dividends

To maintain our qualification as a REIT, U.S. federal income tax law generally requires that we distribute at least 90% of our REIT taxable income annually, determined without regard to the deduction for dividends paid and excluding net capital gains. We must pay tax at regular corporate rates to the extent that we annually distribute less than 100% of our taxable income. Before we pay any dividend, whether for U.S. federal income tax purposes or otherwise, we must first meet both our operating requirements and debt service on our repurchase agreements and other debt payable. If our cash available for distribution is less than our REIT taxable income, we could be required to sell assets or borrow funds to make cash distributions, or we may make a portion of the required distribution in the form of a taxable stock distribution or distribution of debt securities.

As discussed above, our distribution requirements are based on REIT taxable income rather than U.S. GAAP net income. The primary differences between our REIT taxable income and U.S. GAAP net income are: (i) unrealized gains and losses on investments that we have elected the fair value option for that are included in current U.S. GAAP income but are excluded from REIT taxable income until realized or settled; (ii) gains and losses on derivative instruments that are included in current U.S. GAAP net income but are excluded from REIT taxable income until realized; and (iii) temporary differences related to amortization of premiums and discounts on investments. For additional information regarding the characteristics of our dividends, refer to Note 12 – "Stockholders' Equity" of our annual report on Form 10-K for the year ended December 31, 2020.

Unrelated Business Taxable Income

We have not engaged in transactions that would result in a portion of our income being treated as unrelated business taxable income.

Exposure to Financial Counterparties

We finance a substantial portion of our investment portfolio through repurchase agreements. Under these agreements, we pledge assets from our investment portfolio as collateral. Additionally, certain counterparties may require us to provide cash collateral in the event the market value of the assets declines to maintain a contractual repurchase agreement collateral ratio. If a counterparty were to default on its obligations, we would be exposed to potential losses to the extent the fair value of collateral pledged by us to the counterparty including any accrued interest receivable on such collateral exceeded the amount loaned to us by the counterparty plus interest due to the counterparty.

As of June 30, 2021, no counterparties held collateral that exceeded the amounts borrowed under the related repurchase agreements by more than $68.7 million, or 5% of our stockholders' equity. The following table summarizes our exposure to counterparties by geographic concentration as of June 30, 2021. The information is based on the geographic headquarters of the counterparty or counterparty's parent company. However, our repurchase agreements are generally denominated in U.S. dollars.

Other Matters

We believe that we satisfied each of the asset tests in Section 856(c)(4) of the Internal Revenue Code of 1986, as amended (the "Code") for the period ended June 30, 2021, and that our proposed method of operation will permit us to satisfy the asset tests, gross income tests, and distribution and stock ownership requirements for our taxable year that will end on December 31, 2021.

At all times, we intend to conduct our business so that neither we nor our Operating Partnership nor the subsidiaries of our Operating Partnership are required to register as an investment company under the 1940 Act. If we were required to register as an investment company, then our use of leverage would be substantially reduced. Because we are a holding company that conducts our business through our Operating Partnership and the Operating Partnership’s wholly-owned or majority-owned subsidiaries, the securities issued by these subsidiaries that are excepted from the definition of "investment company" under Section 3(c)(1) or Section 3(c)(7) of the 1940 Act, together with any other investment securities the Operating Partnership may own, may not have a combined value in excess of 40% of the value of the Operating Partnership’s total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis, which we refer to as the 40% test. This requirement limits the types of businesses in which we are permitted to engage in through our subsidiaries. In addition, we believe neither

57

we nor the Operating Partnership are considered an investment company under Section 3(a)(1)(A) of the 1940 Act because they do not engage primarily or hold themselves out as being engaged primarily in the business of investing, reinvesting or trading in securities. Rather, through the Operating Partnership’s wholly-owned or majority-owned subsidiaries, we and the Operating Partnership are primarily engaged in the non-investment company businesses of these subsidiaries. IAS Asset I LLC and certain of the Operating Partnership’s other subsidiaries that we may form in the future rely upon the exclusion from the definition of "investment company" under the 1940 Act provided by Section 3(c)(5)(C) of the 1940 Act, which is available for entities "primarily engaged in the business of purchasing or otherwise acquiring mortgages and other liens on and interests in real estate." This exclusion generally requires that at least 55% of each subsidiary’s portfolio be comprised of qualifying assets and at least 80% be comprised of qualifying assets and real estate-related assets (and no more than 20% comprised of miscellaneous assets). We calculate that as of June 30, 2021, we conducted our business so as not to be regulated as an investment company under the 1940 Act.

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

The primary components of our market risk are related to interest rate, principal prepayment and market value. While we do not seek to avoid risk completely, we believe the risk can be quantified from historical experience and we seek to actively manage that risk, to earn sufficient compensation to justify taking those risks and to maintain capital levels consistent with the risks we undertake.

For additional discussion of market risk associated with the COVID-19 pandemic, see Part I. Item 1 - Risk Factors of our annual report on Form 10-K for the year ended December 31, 2020.

Interest Rate Risk

Interest rate risk is highly sensitive to many factors, including governmental, monetary and tax policies, domestic and international economic and political considerations, and other factors beyond our control. We are subject to interest rate risk in connection with our investments and our repurchase agreements. Our repurchase agreements are typically short-term in nature and are periodically refinanced at current market rates. We typically mitigate this interest rate risk by utilizing derivative contracts, primarily interest rate swap agreements, futures contracts and TBAs.

Interest Rate Effect on Net Interest Income

Our operating results depend in large part upon differences between the yields earned on our investments and our cost of borrowing and interest rate hedging activities. During periods of rising interest rates, the borrowing costs associated with our investments tend to increase while the income earned on our fixed interest rate investments may remain substantially unchanged. This increase in borrowing costs results in the narrowing of the net interest spread between the related assets and borrowings and may even result in losses. Further, defaults could increase and result in credit losses to us, which could adversely affect our liquidity and operating results. Such delinquencies or defaults could also have an adverse effect on the spread between interest-earning assets and interest-bearing liabilities.

Hedging techniques are partly based on assumed levels of prepayments of our RMBS. If prepayments are slower or faster than assumed, the life of the RMBS will be longer or shorter, which would reduce the effectiveness of any hedging strategies we may use and may cause losses on such transactions. Hedging strategies involving the use of derivative securities are highly complex and may produce volatile returns.

Interest Rate Effects on Fair Value

Another component of interest rate risk is the effect that changes in interest rates will have on the market value of the assets that we acquire. We face the risk that the market value of our assets will increase or decrease at different rates than those of our liabilities, including our hedging instruments.

We primarily assess our interest rate risk by estimating the duration of our assets and the duration of our liabilities. Duration measures the market price volatility of financial instruments as interest rates change. We generally calculate duration using various financial models and empirical data. Different models and methodologies can produce different duration values for the same securities.

The impact of changing interest rates on fair value can change significantly when interest rates change materially. Therefore, the volatility in the fair value of our assets could increase significantly in the event interest rates change materially. In addition, other factors impact the fair value of our interest rate-sensitive investments and hedging instruments, such as the shape of the yield curve, market expectations as to future interest rate changes and other market conditions. Accordingly, changes in actual interest rates may have a material adverse effect on us.

58

Spread Risk

We employ a variety of spread risk management techniques that seek to mitigate the influences of spread changes on our book value and our liquidity to help us achieve our investment objectives. We refer to the difference between interest rates on our investments and interest rates on risk free instruments as spreads. The yield on our investments changes over time due to the level of risk free interest rates, the creditworthiness of the security, and the price of the perceived risk. The change in the market yield of our interest rate hedges also changes primarily with the level of risk free interest rates. We manage spread risk through careful asset selection, sector allocation, regulating our portfolio value-at-risk, and maintaining adequate liquidity. Changes in spreads impact our book value and our liquidity and could cause us to sell assets and to change our investment strategy to maintain liquidity and preserve book value.

Unprecedented government responses to the COVID-19 pandemic, including fiscal stimulus, monetary policy actions, and various purchase and financing programs have impacted and will continue to impact credit spreads.

Prepayment Risk

As we receive prepayments of principal on our investments, premiums paid on these investments are amortized against interest income. In general, an increase in prepayment rates will accelerate the amortization of purchase premiums, thereby reducing the interest income earned on the investments. Conversely, discounts on such investments are accreted into interest income. In general, an increase in prepayment rates will accelerate the accretion of purchase discounts, thereby increasing the interest income earned on the investments.

Historically low interest rates, high interest rate volatility, uncertainties related to government policies on mortgage finance in response to the COVID-19 pandemic, social distancing, and other factors have made it more difficult to predict prepayment levels for the securities in our portfolio. As a result, it is possible that realized prepayment behavior will be materially different from our expectations.

Extension Risk

We compute the projected weighted average life of our investments based upon assumptions regarding the rate at which the borrowers will prepay the underlying mortgages. In general, when a fixed-rate or hybrid adjustable-rate security is acquired with borrowings, we may, but are not required to, enter into an interest rate swap agreement or other hedging instrument that effectively fixes our borrowing costs for a period close to the anticipated average life of the fixed-rate portion of the related assets. This strategy is designed to protect us from rising interest rates, because the borrowing costs are fixed for the duration of the fixed-rate portion of the related target asset.

However, if prepayment rates decrease in a rising interest rate environment, then the life of the fixed-rate portion of the related assets could extend beyond the term of the swap agreement or other hedging instrument. This could have a negative impact on our results from operations, as borrowing costs would no longer be fixed after the end of the hedging instrument, while the income earned on the hybrid adjustable-rate assets would remain fixed. This situation may also cause the market value of our hybrid adjustable-rate assets to decline, with little or no offsetting gain from the related hedging transactions. In extreme situations, we may be forced to sell assets to maintain adequate liquidity, which could cause us to incur losses.

Market Risk

Market Value Risk

Our available-for-sale securities are reflected at their estimated fair value with unrealized gains and losses excluded from earnings and reported in other comprehensive income under ASC Topic 320. The estimated fair value of these securities fluctuates primarily due to changes in interest rates and other factors. Generally, in a rising interest rate environment, the estimated fair value of these securities would be expected to decrease; conversely, in a falling interest rate environment, the estimated fair value of these securities would be expected to increase.

The COVID-19 pandemic and related preventative measures have caused unprecedented volatility and illiquidity in fixed income markets. The amount of financing we receive under our repurchase agreements is directly related to our counterparties’ valuation of our assets that collateralize the outstanding repurchase agreement financing. As a result, if these market conditions persist, margin call risk remains elevated and our operating results and financial condition may be materially impacted.

The sensitivity analysis table presented below shows the estimated impact of an instantaneous parallel shift in the yield curve, up and down 50 and 100 basis points, on the market value of our interest rate-sensitive investments and net interest income, including net interest paid or received under interest rate swaps, at June 30, 2021, assuming a static portfolio and constant financing and credit spreads. When evaluating the impact of changes in interest rates, prepayment assumptions and principal reinvestment rates are adjusted based on our Manager’s expectations. The analysis presented utilized assumptions, models and estimates of our Manager based on our Manager’s judgment and experience.

59

Change in Interest Rates	Percentage Change in Projected Net Interest Income		Percentage Change in Projected Portfolio Value
+1.00%	(3.60)	%	(2.55)	%
+0.50%	0.02	%	(1.03)	%
-0.50%	(9.10)	%	(0.11)	%
-1.00%	(22.88)	%	(1.82)	%

Certain assumptions have been made in connection with the calculation of the information set forth in the foregoing interest rate sensitivity table and, as such, there can be no assurance that assumed events will occur or that other events will not occur that would affect the outcomes. The base interest rate scenario assumes interest rates at June 30, 2021. Furthermore, while we generally expect to retain such assets and the associated interest rate risk to maturity, future purchases and sales of assets could materially change our interest rate risk profile.

Our scenario analysis assumes a floor of 0% for U.S. Treasury yields. Given the relatively low interest rates at June 30, 2021, to be consistent, we also applied a floor of 0% for all related funding costs. Due to this floor, we anticipate that declines in funding costs resulting from a significant interest rate decrease would be limited. At the same time, increases in prepayment speed forecasts resulting from lower rates are also limited by this assumption. For purposes of our calculations, the net interest income projections are determined for each specific security. In contrast, for the market value analysis, this floor may limit the gains in market values in scenarios where the interest rate drops significantly.

The information set forth in the interest rate sensitivity table above and all related disclosures constitutes forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Actual results could differ significantly from those estimated in the foregoing interest rate sensitivity table.

Real Estate Risk

Residential and commercial property values are subject to volatility and may be adversely affected by a number of factors, including, but not limited to: national, regional and local economic conditions (which may be adversely affected by industry slowdowns and other factors); local real estate conditions (such as the supply of housing stock or other property sectors); changes or continued weakness in specific industry segments; construction quality, age and design; demographic factors; and retroactive changes to building or similar codes. In addition, decreases in property values reduce the value of the collateral and the potential proceeds available to a borrower to repay our loans, which could also cause us to suffer losses.

Credit Risk

We retain the risk of potential credit losses on all of our residential and commercial mortgage investments. We seek to manage this risk through our pre-acquisition due diligence process. In addition, we re-evaluate the credit risk inherent in our investments on a regular basis pursuant to fundamental considerations such as GDP, unemployment, interest rates, retail sales, store closings/openings, corporate earnings, housing inventory, affordability and regional home price trends. We also review key loan credit metrics including, but not limited to, payment status, current loan-to-value ratios, current borrower credit scores and debt yields. These characteristics assist in determining the likelihood and severity of loan loss as well as prepayment and extension expectations. We then perform structural analysis under multiple scenarios to establish likely cash flow profiles and credit enhancement levels relative to collateral performance projections. This analysis allows us to quantify our opinions of credit quality and fundamental value, which are key drivers of portfolio management decisions.

The conditions related to the COVID-19 pandemic have adversely affected the fundamentals of many of our portfolio investments. The significant decrease in economic activity and/or resulting decline in the housing market could have an adverse effect on the value of our investments in mortgage real estate-related assets. Further, because of the COVID-19 pandemic’s impact on the overall economy, such as rising unemployment levels or changes in consumer behavior related to loans as well as government policies and pronouncements, borrowers may experience difficulties meeting their obligations or seek to forbear or further forbear payment on or refinance their mortgage loans to avail themselves of lower rates. In addition to residential mortgage-related assets, the adverse economic conditions could negatively impact tenants underlying our commercial property assets resulting in potential delinquencies, defaults or declines in asset values. In many instances, tenants are foregoing rent payments or seeking forbearance. As a result, loans may experience increased delinquencies and defaults, which could impact the fundamental performance of our mortgage-backed securities. Further, we expect credit rating agencies to reassess transactions that are negatively impacted by these adverse changes. This may result in our investments being downgraded by credit rating agencies.

60

Foreign Exchange Rate Risk

We have an investment of €10.4 million in an unconsolidated joint venture whose net assets and results of operations are exposed to foreign currency translation risk when translated in U.S. dollars upon consolidation. We seek to hedge our foreign currency exposures by purchasing currency forward contracts.

Risk Management

To the extent consistent with maintaining our REIT qualification, we seek to manage risk exposure to protect our investment portfolio against the effects of major interest rate changes. We generally seek to manage this risk by:

•monitoring and adjusting, if necessary, the reset index and interest rate related to our target assets and our financings;

•attempting to structure our financing agreements to have a range of different maturities, terms, amortizations and interest rate adjustment periods;

•exploring options to obtain financing arrangements that are not marked to market;

•using hedging instruments, primarily interest rate swap agreements but also financial futures, options, interest rate cap agreements, floors and forward sales to adjust the interest rate sensitivity of our target assets and our borrowings; and

•actively managing, on an aggregate basis, the interest rate indices, interest rate adjustment periods, and gross reset margins of our target assets and the interest rate indices and adjustment periods of our financings.

61

ITEM 4.     CONTROLS AND PROCEDURES.

Our management is responsible for establishing and maintaining disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act.

We have evaluated, with the participation of our principal executive officer and principal financial officer, the effectiveness of our disclosure controls and procedures as of June 30, 2021. Based upon our evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Changes in Internal Control over Financial Reporting    

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the quarter ended June 30, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Organization and Business Operations

Organization and Business Operations

Invesco Mortgage Capital Inc. (the "Company" or "we") is a Maryland corporation primarily focused on investing in, financing and managing mortgage-backed securities ("MBS") and other mortgage-related assets.

We currently invest in:

•Residential mortgage-backed securities ("RMBS") that are guaranteed by a U.S. government agency such as the Government National Mortgage Association ("Ginnie Mae"), or a federally chartered corporation such as the Federal National Mortgage Association ("Fannie Mae") or the Federal Home Loan Mortgage Corporation ("Freddie Mac") (collectively "Agency RMBS");

•Commercial mortgage-backed securities ("CMBS") that are not guaranteed by a U.S. government agency or a federally chartered corporation ("non-Agency CMBS");

•RMBS that are not guaranteed by a U.S. government agency or a federally chartered corporation ("non-Agency RMBS");

•Commercial mortgage loans; and

•Other real estate-related financing agreements.

We have also historically invested in:

•CMBS that are guaranteed by a U.S. government agency such as Ginnie Mae or a federally chartered corporation such as Fannie Mae or Freddie Mac (collectively "Agency CMBS");

•Credit risk transfer securities that are unsecured obligations issued by government-sponsored enterprises ("GSE CRT"); and

•Residential mortgage loans.

We conduct our business through IAS Operating Partnership L.P. (the "Operating Partnership") and have one operating segment. We are externally managed and advised by Invesco Advisers, Inc. (our "Manager"), a registered investment adviser and an indirect, wholly-owned subsidiary of Invesco Ltd. ("Invesco"), a leading independent global investment management firm.

We elected to be taxed as a real estate investment trust ("REIT") for U.S. federal income tax purposes under the provisions of the Internal Revenue Code of 1986. To maintain our REIT qualification, we are generally required to distribute at least 90% of our REIT taxable income to our stockholders annually. We operate our business in a manner that permits our exclusion from the "Investment Company" definition under the Investment Company Act of 1940, as amended (the "1940 Act").

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

Certain disclosures included in our Annual Report on Form 10-K are not required to be included on an interim basis in our quarterly reports on Form 10-Q. We have condensed or omitted these disclosures. Therefore, this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020.

Our condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") and consolidate the financial statements of the Company and our controlled subsidiaries. All significant intercompany transactions, balances, revenues and expenses are eliminated upon consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for a fair statement of our financial condition and results of operations for the periods presented.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Examples of estimates include, but are not limited to, estimates of the fair values of financial instruments, interest income on mortgage-backed and credit risk transfer securities and allowances for credit losses. Actual results may differ from those estimates.

Significant Accounting Policies

There have been no changes to our accounting policies included in Note 2 to the consolidated financial statements of our Annual Report on Form 10-K for the year ended December 31, 2020.

Accounting Pronouncements Recently Issued

In January 2021, the Financial Accounting Standards Board expanded existing accounting guidance for evaluating the effects of reference rate reform on financial reporting. The new guidance expands the temporary optional expedients and exceptions to U.S. GAAP for contract modifications, hedge accounting and other relationships that reference London Interbank Overnight Financing Rate ("LIBOR") to apply to all derivative instruments affected by the market-wide change in the interest rates used for discounting, margining or contract price alignment (commonly referred to as the discounting transition). The guidance can be applied as of January 1, 2020. We are evaluating our contracts that are eligible for modification relief and may apply the elections prospectively as needed. We are currently evaluating what impact the guidance will have on our consolidated financial statements.

Mortgage-Backed and Credit Risk Transfer Securities

Mortgage-Backed and Credit Risk Transfer Securities

During the first half of 2020, we experienced unprecedented market conditions as a result of the COVID-19 pandemic and sold a substantial portion of our MBS and GSE CRT portfolio to generate liquidity and reduce leverage. We resumed investing in Agency RMBS in July 2020.

The following tables summarize our MBS portfolio by asset type as of June 30, 2021 and December 31, 2020.

June 30, 2021

Total	9,081,643	(360,482)	8,721,161	9,502	8,730,663	2.10	%

(1)Period-end weighted average yield is based on amortized cost as of June 30, 2021 and incorporates future prepayment and loss assumptions.

(2)Agency collateralized mortgage obligation ("Agency-CMO") are interest-only securities ("Agency IO").

(3)Non-Agency RMBS is 64.5% fixed rate, 34.5% variable rate, and 1.0% floating rate based on fair value. Coupon payments on variable rate investments are based upon changes in the underlying Hybrid adjustable-rate mortgage ("ARM") loan coupons, while coupon payments on floating rate investments are based upon a spread to a reference index.

(4)Of the total discount in non-Agency RMBS, $2.1 million is non-accretable (calculated using the principal/notional balance) based on estimated future cash flows of the securities.

(5)Non-Agency RMBS includes interest-only securities ("non-Agency IO") which represent 98.2% of principal/notional balance, 47.0% of amortized cost and 30.0% of fair value.

(2)All Agency-CMO are Agency IO.

(3)Non-Agency RMBS is 67.3% fixed rate, 31.8% variable rate and 0.9% floating rate based on fair value. Coupon payments on variable rate investments are based upon changes in the underlying Hybrid ARM loan coupons, while coupon payments on floating rate investments are based upon a spread to a reference index.

The following table presents the fair value of our available-for-sale securities and securities accounted for under the fair value option by asset type as of June 30, 2021 and December 31, 2020. We have elected the fair value option for all of our RMBS interest-only securities and our MBS purchased on or after September 1, 2016. As of June 30, 2021 and December 31, 2020, approximately 99% of our MBS are accounted for under the fair value option.

(3)Fair value option has been elected for all non-Agency RMBS in an unrealized loss position.

As of December 31, 2020, we had recorded an allowance for credit losses of $1.8 million on a single non-Agency CMBS on our condensed consolidated balance sheet. We recorded an $830,000 and a $1.8 million decrease in the provision for credit losses on our condensed consolidated statement of operations during the three and six months ended June 30, 2021, respectively. As of June 30, 2021, we do not have an allowance for credit losses recorded on our condensed consolidated balance sheet. We did not record any provisions for credit losses during the three and six months ended June 30, 2020. During the three and six months ended June 30, 2020, we recorded impairments of $6.3 million and $85.1 million, respectively, on our condensed consolidated statement of operations because we intended to sell or more likely than not would be required to sell the securities before recovery of amortized cost basis. The following table presents a roll-forward of our allowance for credit losses.

Repurchase Agreements

In the first half of 2020, we experienced unprecedented market conditions as a result of the COVID-19 pandemic. We received an unusually high number of margin calls from our repurchase agreement counterparties during March 2020 following significant spread widening in both Agency and non-Agency securities. As a result, we were unable to meet margin calls and were not in compliance with all of the financial covenants of our repurchase agreements as of March 31, 2020. While certain of our repurchase agreement counterparties permitted our repurchase agreements to remain outstanding while we were not in compliance, other counterparties seized and sold securities that we had posted as collateral for our repurchase agreements. As of May 7, 2020, we repaid all of our repurchase agreements that may have been in default. Gains and losses associated with the termination of these repurchase agreements during the three and six months ended June 30, 2020 are reported as net gain (loss) on extinguishment of debt in our condensed consolidated statement of operations.

We resumed financing the purchase of Agency RMBS with repurchase agreements in July 2020. These repurchase agreements generally bear interest at a contractually agreed upon rate and have maturities of approximately one to six months. Repurchase agreements are accounted for as secured borrowings since we maintain effective control of the financed assets. The repurchase agreements are subject to certain financial covenants. We were in compliance with all of these covenants as of June 30, 2021.

Secured Loans

During the year ended December 31, 2020, IAS Services LLC, our former wholly-owned captive insurance subsidiary, fully repaid its outstanding secured loans from the Federal Home Loan Bank of Indianapolis ("FHLBI").

The following table summarizes the fair value of collateral that we pledged and held under our repurchase agreements, interest rate swaps, currency forward contracts and to-be-announced securities forward contracts ("TBAs") as of June 30, 2021 and December 31, 2020. Refer to Note 2 - "Summary of Significant Accounting Policies - Fair Value Measurements" of our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 for a description of how we determine fair value. Agency RMBS collateral pledged is included in mortgage-backed securities on our condensed consolidated balance sheets. Cash collateral pledged on centrally cleared interest rate swaps and currency forward contracts is classified as restricted cash on our condensed consolidated balance sheets. Cash collateral pledged on repurchase agreements and TBAs accounted for as derivatives is classified as due from counterparties on our condensed consolidated balance sheets.

Cash collateral held that is not restricted for use is included in cash and cash equivalents on our condensed consolidated balance sheets and the liability to return the collateral is included in collateral held payable. Non-cash collateral held is only recognized if the counterparty defaults or if we sell the pledged collateral. As of June 30, 2021 and December 31, 2020, we did not recognize any non-cash collateral held on our condensed consolidated balance sheets.

Repurchase Agreements

Collateral pledged with our repurchase agreement counterparties is segregated in our books and records. The repurchase agreement counterparties have the right to resell and repledge the collateral posted but have the obligation to return the pledged collateral, or substantially the same collateral if agreed to by us, upon maturity of the repurchase agreement. Under the repurchase agreements, the respective lender retains the contractual right to mark the underlying collateral to fair value. We would be required to provide additional collateral to fund margin calls if the value of pledged assets declined. We intend to maintain a level of liquidity that will enable us to meet margin calls.

Our repurchase agreement collateral pledged ratio (MBS pledged as collateral/amount outstanding) was 105% as of June 30, 2021 (December 31, 2020: 105%).

Interest Rate Swaps

As of June 30, 2021 and December 31, 2020, all of our interest rate swaps were centrally cleared by a registered clearing organization such as the Chicago Mercantile Exchange ("CME") and LCH Limited ("LCH") through a Futures Commission Merchant ("FCM"). We are required to pledge initial margin and daily variation margin for our centrally cleared interest rate swaps that is based on the fair value of our contracts as determined by our FCM. Collateral pledged with our FCM is segregated in our books and records and can be in the form of cash or securities. Daily variation margin for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral and is recorded as gain (loss) on derivative instruments, net in our condensed consolidated statements of operations. Certain of our FCM agreements include cross default provisions.

TBAs and Currency Forward Contracts

Our TBAs and currency forward contracts provide for bilateral collateral pledging based on market value as determined by our counterparties. Collateral pledged with our TBA and currency forward counterparties is segregated in our books and records and can be in the form of cash or securities. Our counterparties have the right to repledge the collateral posted and have the obligation to return the pledged collateral, or substantially the same collateral, if agreed to by us, as the market value of the contracts changes.

Refer to Note 7 - "Collateral Positions" for further information regarding our collateral pledged to and received from our derivative counterparties.

Interest Rate Swaps

Our repurchase agreements are usually settled on a short-term basis ranging from one to six months. At each settlement date, we typically refinance each repurchase agreement at the market interest rate at that time. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposures to interest rate movements. To accomplish these objectives, we primarily use interest rate swaps as part of our interest rate risk management strategy. Under the terms of the majority our interest rate swap contracts, we make fixed-rate payments to a counterparty in exchange for the receipt of variable-rate amounts over the agreed upon term without exchange of the underlying notional amount. To a lesser extent, we also enter into interest rate swap contracts whereby we make floating-rate payments to a counterparty in exchange for the receipt of fixed-rate amounts as part of our overall risk management strategy.

Amounts recorded in accumulated other comprehensive income ("AOCI") before we discontinued cash flow hedge accounting for our interest rate swaps are reclassified to interest expense on repurchase agreements on the condensed

consolidated statements of operations as interest is accrued and paid on the related repurchase agreements over the remaining life of the interest rate swap agreements. We reclassified $5.4 million and $10.8 million as a decrease (June 30, 2020: $4.5 million and $14.6 million as a decrease) to interest expense for the three and six months ended June 30, 2021, respectively. We increased the amount of gains and losses reclassified as a decrease to interest expense during the three and six months ended June 30, 2020 by $2.7 million because it was probable that the original forecasted repurchase agreement transactions would not occur by the end of the originally specified time period. During the next 12 months, we estimate that $21.2 million will be reclassified as a decrease to interest expense, repurchase agreements. As of June 30, 2021, $41.3 million (December 31, 2020: $52.1 million) of unrealized gains on discontinued cash flow hedges, net are still included in accumulated other comprehensive income and will be reclassified as a decrease to interest expense, repurchase agreements over a period of time through December 15, 2023.

As of June 30, 2021 and December 31, 2020, we had interest rate swaps whereby we pay interest at a fixed rate and receive floating interest based on 1-month LIBOR with the following maturities outstanding, excluding interest rate swaps with forward start dates.

We did not hold any interest rate swaps with forward start dates as of December 31, 2020.

As of June 30, 2021, we had interest rate swaps whereby we pay floating interest based on 1-month LIBOR and receive interest at a fixed rate with the following maturities outstanding. We did not hold any such interest rate swaps as of December 31, 2020.

Swaptions and Currency Forward Contracts

We periodically purchase interest rate swaptions to help mitigate the potential impact of increases or decreases in interest rates on the performance of our Agency RMBS portfolio (referred to as "convexity risk"). The interest rate swaptions provide us the option to enter into interest rate swap agreements for a predetermined notional amount, stated term and pay and receive interest rates in the future. The premium paid for interest rate swaptions is reported as a derivative asset in our condensed consolidated balance sheets. The premium is valued at an amount equal to the fair value of the swaption that would have the effect of closing the position adjusted for nonperformance risk, if any. The difference between the premium and the fair value of the swaption is reported in gain (loss) on derivative instruments, net in our condensed consolidated statements of operations. If an interest rate swaption expires unexercised, the loss on the interest rate swaption would equal the premium paid. If we sell or exercise an interest rate swaption, the realized gain or loss on the interest rate swaption would equal the difference between the cash or the fair value of the underlying interest rate swap received and the premium paid.

We use currency forward contracts to help mitigate the potential impact of changes in foreign currency exchange rates on our investments denominated in foreign currencies. We recognize realized and unrealized gains and losses associated with the purchases or sales of currency forward contracts in gain (loss) on derivative instruments, net in our condensed consolidated statements of operations. As of June 30, 2021, we had $18.0 million (December 31, 2020: $33.1 million) of notional amount of currency forward contracts related to an investment in an unconsolidated venture denominated in Euro.

Credit Derivatives

Our GSE CRTs purchased prior to August 24, 2015 were accounted for as hybrid financial instruments consisting of a debt host contract and an embedded credit derivative. Embedded derivatives associated with GSE CRTs were recorded within mortgage-backed and credit risk transfer securities, at fair value, on the condensed consolidated balance sheets.

TBAs

We primarily use TBAs that we do not intend to physically settle on the contractual settlement date as an alternative means of investing in and financing Agency RMBS. The following table summarizes certain characteristics of our TBAs accounted for as derivatives as of June 30, 2021 and December 31, 2020.

Offsetting Assets and Liabilities

Offsetting Assets and Liabilities

Certain of our repurchase agreements and derivative transactions are governed by underlying agreements that generally provide for a right of offset under master netting arrangements (or similar agreements) in the event of default or in the event of bankruptcy of either party to the transactions. Assets and liabilities subject to such arrangements are presented on a gross basis in the condensed consolidated balance sheets.

The following tables present information about the assets and liabilities that are subject to master netting agreements (or similar agreements) and can potentially be offset on our condensed consolidated balance sheets at June 30, 2021 and December 31, 2020. The daily variation margin payment for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral. As of June 30, 2021, our derivative liability of $17.2 million (December 31, 2020: derivative liability of $5.5 million) related to centrally cleared interest rate swaps is not included in the table below as a result of this characterization of daily variation margin.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

A three-level valuation hierarchy exists for disclosure of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect our market assumptions. The three levels are defined as follows:

•Level 1 Inputs – Quoted prices for identical instruments in active markets.

•Level 2 Inputs – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

•Level 3 Inputs – Instruments with primarily unobservable value drivers.

The following tables present our assets and liabilities measured at fair value on a recurring basis.

(2)Investments in unconsolidated ventures are valued using the net asset value ("NAV") as a practical expedient and are not subject to redemption, although investors may sell or transfer their interest at the approval of the general partner of the underlying funds. As of June 30, 2021 and December 31, 2020, the weighted average remaining term of our investments in unconsolidated ventures was 1.2 years and 1.5 years, respectively.

(3)Includes $20.8 million and $23.1 million of a commercial loan as of June 30, 2021 and December 31, 2020, respectively. We value the loan based on a third party appraisal.

Unrealized gains and losses on our commercial loan are included in gain (loss) on investments, net in our condensed consolidated statements of operations. We elected the fair value option for our commercial loan on January 1, 2020 when we implemented the new accounting guidance for how entities report credit losses for assets measured at amortized cost.

The following describes our methods for estimating the fair value for financial instruments not carried at fair value on the condensed consolidated balance sheets.

•The estimated fair value of repurchase agreements is a Level 3 fair value measurement based on an expected present value technique. This method discounts future estimated cash flows using rates we determined best reflect current market interest rates that would be offered for repurchase agreements with similar characteristics and credit quality.

Our Manager is at all times subject to the supervision and oversight of our Board of Directors and has only such functions and authority as we delegate to it. Under the terms of our management agreement, our Manager and its affiliates provide us with our management team, including our officers and appropriate support personnel. Each of our officers is an employee of our Manager or one of its affiliates. We do not have any employees. Our Manager is not obligated to dedicate any of its employees exclusively to us, nor is our Manager obligated to dedicate any specific portion of time to our business. During the three and six months ended June 30, 2021, we reimbursed our Manager $261,000 and $559,000 (June 30, 2020: $286,000 and $558,000) for costs of support personnel, respectively.

We invested $1.9 million in money market or mutual funds managed by affiliates of our Manager as of December 31, 2020. The investments are reported as cash and cash equivalents on our condensed consolidated balance sheets as they are highly liquid and have original or remaining maturities of three months or less when purchased. We did not have any investments in money market of mutual funds managed by affiliates of our Manager as of June 30, 2021.

Management Fee

Our management fee is equal to 1.50% of our stockholders' equity per annum. For purposes of calculating the management fee, stockholders' equity is calculated as average month-end stockholders' equity for the prior calendar quarter as determined in accordance with U.S. GAAP. Stockholders' equity may exclude one-time events due to changes in U.S. GAAP and certain non-cash items upon approval by a majority of our independent directors.

We do not pay any management fees on our investments in unconsolidated ventures that are managed by an affiliate of our Manager.

Expense Reimbursement

We are required to reimburse our Manager for operating expenses incurred on our behalf, including directors and officers insurance, accounting services, auditing and tax services, filing fees, and miscellaneous general and administrative costs. Our reimbursement obligation is not subject to any dollar limitation.

Equity [Abstract]

Stockholders' Equity

Stockholders’ Equity

Preferred Stock

On June 16, 2021 we redeemed all issued and outstanding shares of our Series A Preferred Stock for $140.0 million plus accrued and unpaid dividends. The cash redemption price for each share of Series A Preferred Stock was $25.00. The excess of the consideration transferred over carrying value is accounted for as a deemed dividend and resulted in a reduction of $4.7 million in net income (loss) attributable to common stockholders during the three and six months ended June 30, 2021. Prior to redemption, holders of our Series A Preferred Stock were entitled to receive dividends at an annual rate of 7.75% of the liquidation preference of $25.00 per share or $1.9375 per share per annum. Dividends were cumulative and payable quarterly in arrears.

Holders of our Series B Preferred Stock are entitled to receive dividends at an annual rate of 7.75% of the liquidation preference of $25.00 per share or $1.9375 per share per annum until December 27, 2024. After December 27, 2024, holders are entitled to receive dividends at a floating rate equal to three-month LIBOR plus a spread of 5.18% of the $25.00 liquidation preference per annum. Dividends are cumulative and payable quarterly in arrears.

Holders of our Series C Preferred Stock are entitled to receive dividends at an annual rate of 7.50% of the liquidation preference of $25.00 per share or $1.875 per share per annum until September 27, 2027. After September 27, 2027, holders are entitled to receive dividends at a floating rate equal to three-month LIBOR plus a spread of 5.289% of the $25.00 liquidation preference per annum. Dividends are cumulative and payable quarterly in arrears.

We have the option to redeem shares of our Series B Preferred Stock after December 27, 2024 and shares of our Series C Preferred Stock after September 27, 2027 for $25.00 per share, plus any accumulated and unpaid dividends through the date of the redemption. Shares of Series B and Series C Preferred Stock are not redeemable, convertible into or exchangeable for any other property or any other securities of the Company before those times, except under circumstances intended to preserve our qualification as a REIT or upon the occurrence of a change in control.

As of June 30, 2021, we may sell up to 5,500,000 shares of our preferred stock from time to time in at-the-market or privately negotiated transactions under an equity distribution agreement with a placement agent. These shares are registered with the SEC under our shelf registration statement (as amended and/or supplemented). We have not sold any shares of preferred stock under equity distribution agreements.

Common Stock

In February 2021, we completed a public offering of 27,600,000 shares of common stock at the price of $3.75 per share. Total net proceeds were approximately $103.1 million after deducting offering expenses.

In June 2021, we completed a public offering of 43,125,000 shares of common stock at the price of $3.39 per share. Total net proceeds were approximately $145.9 million after deducting offering expenses.

As of June 30, 2021, we may sell up to 22,060,000 shares of our common stock from time to time in at-the-market or privately negotiated transactions under an equity distribution agreement with a placement agent. These shares are registered with the SEC under our shelf registration statement (as amended and/or supplemented). During the six months ended June 30, 2021, we sold 15,500,000 shares under our equity distribution agreement for proceeds of $57.8 million, net of approximately $831,000 in commissions and fees. We did not sell any shares of common stock under equity distribution agreements during the three months ended June 30, 2021 or the three and six months ended June 30, 2020.

In May 2021, we granted 127,115 restricted shares of common stock to our independent directors. The restricted shares will become unrestricted shares of common stock on the first anniversary of the grant date unless forfeited, subject to certain conditions that accelerate vesting.

Share Repurchase Program

During the three and six months ended June 30, 2021 and 2020, we did not repurchase any shares of our common stock. As of June 30, 2021, we had authority to purchase 18,163,982 shares of our common stock through our share repurchase program.

Stockholders had the opportunity to elect payment of the dividend all in cash or all in common shares, subject to a limit of 10% or approximately $8.2 million of cash in the aggregate (excluding any cash paid in lieu of issuing fractional shares). On June 30, 2020, we paid the dividend through the issuance of 16,338,511 shares of common stock and the payment of approximately $8.2 million in cash. The number of shares included in the dividend was calculated based on the $4.5435 volume weighted average trading price of our common stock on the New York Stock Exchange on June 17, 18 and 19, 2020.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2021

Accounting Policies [Abstract]

Basis of Presentation and Consolidation

Basis of Presentation and Consolidation

Certain disclosures included in our Annual Report on Form 10-K are not required to be included on an interim basis in our quarterly reports on Form 10-Q. We have condensed or omitted these disclosures. Therefore, this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020.

Consolidation

Our condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") and consolidate the financial statements of the Company and our controlled subsidiaries. All significant intercompany transactions, balances, revenues and expenses are eliminated upon consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for a fair statement of our financial condition and results of operations for the periods presented.

Use of Estimates

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Examples of estimates include, but are not limited to, estimates of the fair values of financial instruments, interest income on mortgage-backed and credit risk transfer securities and allowances for credit losses. Actual results may differ from those estimates.

The new guidance expands the temporary optional expedients and exceptions to U.S. GAAP for contract modifications, hedge accounting and other relationships that reference London Interbank Overnight Financing Rate ("LIBOR") to apply to all derivative instruments affected by the market-wide change in the interest rates used for discounting, margining or contract price alignment (commonly referred to as the discounting transition). The guidance can be applied as of January 1, 2020. We are evaluating our contracts that are eligible for modification relief and may apply the elections prospectively as needed. We are currently evaluating what impact the guidance will have on our consolidated financial statements.

Schedule of Offsetting Assets

The following tables present information about the assets and liabilities that are subject to master netting agreements (or similar agreements) and can potentially be offset on our condensed consolidated balance sheets at June 30, 2021 and December 31, 2020. The daily variation margin payment for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral. As of June 30, 2021, our derivative liability of $17.2 million (December 31, 2020: derivative liability of $5.5 million) related to centrally cleared interest rate swaps is not included in the table below as a result of this characterization of daily variation margin.
