NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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 residential and commercial mortgage-backed securities ("MBS") and other mortgage-related assets. 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 conduct our business through IAS Operating Partnership LP (the "Operating Partnership") and have one operating segment.

We have historically invested 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 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");

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

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

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

•Residential and commercial mortgage loans; and

•Other real estate-related financing agreements.

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.

During the six months ended June 30, 2020, we experienced unprecedented market conditions as a result of the COVID-19 pandemic that resulted in a material adverse change in our financial condition. In the three and six months ended June 30, 2020, we recorded a net loss of $299.9 million and $1.9 billion, respectively. Our stockholders' equity declined from $2.9 billion as of December 31, 2019 to $1.2 billion as of June 30, 2020.

Due to significant spread widening in both Agency and non-Agency securities, we received an unusually high number of margin calls from counterparties in the latter half of March 2020. As a result, we were unable to meet margin calls and were not in compliance with the terms of our various borrowings arrangements as of March 31, 2020 as described in Note 6 - "Borrowings". To generate liquidity and reduce leverage, we sold MBS and GSE CRTs for cash proceeds of $23.1 billion and repaid $17.5 billion of our repurchase agreements and $910.0 million of Federal Home Loan Bank of Indianapolis "FHLBI" secured loans during the six months ended June 30, 2020. Our investment portfolio decreased from $21.9 billion as of December 31, 2019 to $1.6 billion as of June 30, 2020 primarily due to these asset sales. We also terminated our entire interest rate swap portfolio as our exposure to interest rate risk decreased as we sold Agency assets.

While the Federal Reserve has taken a number of proactive measures to bolster liquidity, we expect market conditions for the mortgage REIT industry to continue to be challenging due to the uncertainty around the duration and ultimate impact of the COVID-19 pandemic.

Note 2 – 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, 2019.

Our condensed consolidated financial statements have been prepared in accordance with 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

7

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 the 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 recognition 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, 2019 other than as discussed below.

Mortgage-Backed and Credit Risk Transfer Securities

Allowances for Credit Losses on Available-For-Sale Securities

We are not required to measure expected credit losses for situations in which historic credit loss information, adjusted for current conditions and reasonable and supportable forecasts, results in an expectation that nonpayment of the amortized cost basis is zero. We consider our Agency portfolio to have zero loss expectation because (i) there have been no historical credit losses, (ii) full and timely payment of principal and interest is guaranteed by the GSEs and (iii) the yields, while not risk free, generally trade based on prepayment and liquidity risk as opposed to credit risk. Our available-for-sale GSE CRTs are hybrid financial instruments consisting of a debt host contract and an embedded credit derivative. The embedded credit derivative is carried at fair value with changes in fair value reported in earnings.

For non-Agency RMBS and non-Agency CMBS, we use a discounted cash flow method to estimate and recognize an allowance for credit losses. We calculate the allowance for credit losses as the difference between prepayment adjusted contractual cash flows without credit losses and expected cash flows discounted at the effective interest rate used to recognize interest income on the investment. In developing an expectation of credit losses, we use internal models that analyze the loans underlying each investment and evaluate factors including, but not limited to, delinquency status, loan-to-value ratios, borrower credit scores, occupancy status and geographic concentration. We place reliance on these internal models in determining credit quality.

We record an allowance for credit losses as a contra-asset on the condensed consolidated balance sheets and a provision for credit losses in the condensed consolidated statements of operations. Credit losses are accreted into earnings over time at the effective interest rate used to recognize interest income. Subsequent favorable or adverse changes in the amount of expected credit losses are recognized immediately in earnings. If the allowance for credit losses has been reduced to zero, we reflect the remaining favorable changes as a prospective adjustment to the effective interest rate of the investment. The allowance for credit losses is limited to the amount by which the investment’s amortized cost exceeds fair value. When the allowance for credit losses is limited, the effective interest rate used to recognize interest income and accrete credit losses is prospectively adjusted. We do not record an allowance for credit losses when an investment’s fair value exceeds its amortized cost. Recoveries of amounts previously written off relating to improvements in cash flows are recognized in earnings when received. We record provisions for credit losses, reductions in provisions for credit losses, accretion of credit losses, and recoveries of amounts previously written off within gain (loss) on investments, net in our condensed consolidated statements of operations.

When we determine that we intend to sell, or more likely than not will be required to sell, an available-for-sale security in an unrealized loss position before we recover its amortized cost, we write off any allowance for credit losses and write down the investment’s amortized cost to its fair value. We record the write off of the allowance for credit losses and write down of the available-for-sale security within gain (loss) on investments, net in our condensed consolidated statements of operations.

We present accrued interest receivable separately from our investment portfolio on our condensed consolidated balance sheets. We do not estimate an allowance for credit losses on accrued interest receivable because we write off accrued interest receivable as a reduction to interest income if it is not received when due.

Interest Income Recognition

Mortgage-Backed Securities

Interest income on MBS is accrued based on the outstanding principal or notional balance of the securities and their contractual terms. Premiums or discounts are amortized or accreted into interest income over the life of the investment using the effective interest method.

Interest income on our MBS where we may not recover substantially all of our initial investment is based on estimated future cash flows. We estimate future expected cash flows at the time of purchase and determine the effective interest rate based

8

on these estimated cash flows and our purchase price. Over the life of the investments, we update these estimated future cash flows and compute a revised yield based on the current amortized cost of the investment. In situations where an allowance for credit losses is limited by the fair value of the investment, we compute the yield as the rate that equates expected future cash flows to the current fair value of the investment. In estimating these future cash flows, there are a number of assumptions that are subject to uncertainties and contingencies, including but not limited to the rate and timing of principal payments (prepayments, repurchases, defaults and liquidations), the pass through or coupon rate, and interest rate fluctuations. These uncertainties and contingencies are difficult to predict and are subject to future events that may impact our estimate and our interest income. Changes in our original or most recent cash flow projections may result in a prospective change in interest income recognized on these securities, or the amortized cost of these securities. For non-Agency RMBS not of high credit quality, when actual cash flows vary from expected cash flows, the difference is recorded as an adjustment to the amortized cost of the security, unless those changes relate to credit losses that will be reflected in an allowance for credit losses, and the security's yield is revised prospectively.

For Agency RMBS and Agency CMBS that cannot be prepaid in such a way that we would not recover substantially all of our initial investment, interest income recognition is based on contractual cash flows. We do not estimate prepayments in applying the effective interest method.

Fair Value Measurements

As of January 1, 2020, we report our commercial loan at fair value as determined by an independent pricing service. The pricing service values the loan using a discounted cash flow analysis. The yield used in the discounted cash flow analysis is determined by comparing the features of the loan to the interest rates and terms required by lenders in the new loan origination market for similar loans and the yield required by investors acquiring mezzanine loans in the secondary market and a comparison of current market and collateral conditions to those present at origination. We discontinued reporting our commercial loan at amortized cost because we elected the fair value option for this loan in connection with our adoption of the new guidance for reporting credit losses discussed below.

Accounting Pronouncements Recently Adopted

On January 1, 2020, we adopted the accounting guidance that changes how entities report credit losses for assets measured at amortized cost and available-for-sale securities. The new guidance significantly changes how entities measure credit losses for most financial assets, including loans, that are not measured at fair value through net income. The guidance replaces the existing “incurred loss” model with an “expected loss” model for instruments measured at amortized cost and requires entities to record credit allowances for available-for-sale debt securities rather than reduce the carrying amount, as they previously did under the other-than-temporary impairment model. The new guidance also simplifies the accounting model for purchased credit-impaired debt securities and loans and requires that entities record an adjustment to retained earnings on January 1, 2020 for the cumulative effect of adopting the new guidance. We were not required to record a cumulative effect adjustment to retained earnings because all of our purchased credit-impaired securities were in an unrealized gain position as of the implementation date.

The new guidance specifically excludes available-for-sale securities measured at fair value through net income. We elected the fair value option for all MBS purchased on or after September 1, 2016 and GSE CRTs purchased on or after August 24, 2015. Accordingly, the impact of the new guidance on accounting for our debt securities is limited to those securities purchased prior to election of the fair value option and held on January 1, 2020. For further information on the composition of our investment portfolio, see Note 4 - "Mortgage Backed and Credit Risk Transfer Securities". During the three and six months ended June 30, 2020, we recorded $6.3 million and $85.1 million, respectively, of impairment on non-Agency securities that we intend to sell or more likely than not will be required to sell before we recover the amortized cost basis of the security. We recorded the impairment within gain (loss) on investments, net in our condensed consolidated statements of operations. As of June 30, 2020, we have not recorded a credit loss allowance on any of our securities.

We had one commercial loan as of December 31, 2019 that was measured at amortized cost. We implemented the new guidance for this loan by electing the fair value option and recording a cumulative effect adjustment to increase retained earnings by $342,000 on January 1, 2020. We recognized $785,000 and $2.5 million of unrealized losses on our commercial loan in our condensed consolidated statement of operations during the three and six months ended June 30, 2020, respectively.

Accounting Pronouncements Recently Issued

In March 2020, new accounting guidance was issued for evaluating the effects of reference rate reform on financial reporting. The new guidance provides 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" or another reference rate that is expected to be discontinued due to reference rate reform. The guidance may be adopted on or after March 12, 2020 and is only effective for the period from March 12, 2020 through December 31, 2022. We have not yet adopted this guidance and are currently evaluating what impact the guidance will have on our consolidated financial statements.

Note 4 – Mortgage-Backed and Credit Risk Transfer Securities

As discussed in Note 1 - "Organization and Business Operations", we sold MBS and GSE CRTs for cash proceeds of $23.1 billion during the six months ended June 30, 2020 to generate liquidity and reduce leverage given unprecedented market conditions as a result of the COVID-19 pandemic.

The following tables summarize our MBS and GSE CRT portfolio by asset type as of June 30, 2020 and December 31, 2019.

(3)Fair value option has been elected for all Agency CMBS that are in an unrealized loss position.

(4)Includes non-Agency CMBS with a fair value of $181.5 million for which the fair value option has been elected. These securities have unrealized losses of $2.8 million.

(5)Includes non-Agency RMBS and non-Agency IO with a fair value of $17.6 million and $8.5 million, respectively, for which the fair value option has been elected. These securities have unrealized losses of $261,000 and $3.7 million, respectively.

(6)Fair value option has been elected for all GSE CRT that are in an unrealized loss position.

On January 1, 2020, we adopted accounting guidance that requires us to estimate an allowance for credit losses on available-for-sale securities in unrealized loss positions. As of June 30, 2020, we have not recorded an allowance for credit losses on any of our securities. We did not record any provisions for credit losses on our condensed consolidated statement of operations during the three and six months ended June 30, 2020. We recorded impairments of $6.3 million and $85.1 million on our condensed consolidated statement of operations 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.

Prior to January 1, 2020, we assessed our investment securities for other-than-temporary impairment ("OTTI") on a quarterly basis. When the fair value of an investment was less than its amortized cost at the balance sheet date of the reporting

period for which impairment was assessed, the impairment was designated as either "temporary" or "other-than-temporary." This analysis included a determination of estimated future cash flows through an evaluation of the characteristics of the underlying loans and the structural features of the investment. Underlying loan characteristics reviewed included, but were not limited to, delinquency status, loan-to-value ratios, borrower credit scores, occupancy status and geographic concentration.

IAS Services LLC, our wholly-owned subsidiary, is required to purchase and hold Federal Home Loan Bank of Indianapolis ("FHLBI") stock as a condition of membership in the FHLBI. The stock is recorded at cost.

We had a participation interest in a secured loan collateralized by mortgage servicing rights that bears interest at a floating rate based on LIBOR plus a spread. We sold our participation interest for $21.6 million on April 1, 2020. The weighted average asset yield for the participation interest was 5.82% as of December 31, 2019. We recorded a realized loss of $3.8 million upon sale of the participation interest.

We have an investment in a commercial loan that matures in February 2021. The loan had a weighted average coupon rate of 8.67% as of June 30, 2020 and 10.19% as of December 31, 2019. As discussed in Note 2- "Summary of Significant Accounting Policies", we elected the fair value option for this loan on January 1, 2020 and recorded a cumulative effect adjustment to increase retained earnings by $342,000 on January 1, 2020. We recorded an unrealized loss on this loan of $785,000 and $2.5 million during the three and six months ended June 30, 2020, respectively, based on a discounted cash flow valuation prepared by an independent pricing service. We previously reported this loan at amortized cost on our condensed consolidated balance sheet.

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 repaid all of our repurchase agreements as of May 7, 2020 and did not have any repurchase agreement borrowings as of June 30, 2020. The following tables summarize certain characteristics of our borrowings at June 30, 2020 and December 31, 2019.

Secured Loans

As of June 30, 2020, IAS Services LLC had $740.0 million in outstanding secured loans from the FHLBI. These secured loans have variable rates that are based on the FHLBI's short-term cost of funds. For the six months ended June 30, 2020, IAS Services LLC had weighted average borrowings of $1.13 billion with a weighted average borrowing rate of 1.48%, and a weighted average maturity of 0.4 years.

In April 2020, the FHLBI modified the terms of our secured loans because we were not in compliance with all of the financial covenants of our secured loan agreements as of March 31, 2020. The modified loan terms require repayment of our secured loans by December 2020 but allow for prepayment at any time without penalty. We intend to repay our secured loans by December 2020 with proceeds from sales of mortgage-backed securities that are collateralizing our secured loans. We determined that the modification of our loan terms was a troubled debt restructuring that did not impact the accounting for our secured loans.

17

As discussed in Note 5 - "Other Assets," IAS Services LLC is required to purchase and hold a certain amount of FHLBI stock, which is based, in part, upon the outstanding principal balance of secured loans from the FHLBI.

Repurchase Agreements

As discussed in Note 1 - “Organization and Business Operations”, 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 and were not in compliance with all of the financial covenants of our repurchase agreements as of March 31, 2020. Certain of our repurchase agreement counterparties entered into forbearance discussions with us and permitted our repurchase agreements to remain outstanding while we were not in compliance.

In addition, certain of our counterparties seized and sold securities that we had posted as collateral for our repurchase agreements. Gains and losses associated with the termination of these repurchase agreements are reported as a net gain (loss) on extinguishment of debt in our condensed consolidated statement of operations.

We repaid all of our repurchase agreements as of May 7, 2020 and did not have any repurchase agreement borrowings as of June 30, 2020.

Note 7 - Collateral Positions

The following table summarizes the fair value of collateral that we pledged and held under our repurchase agreements, secured loans, interest rate swaps and currency forward contracts as of June 30, 2020 and December 31, 2019. 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, 2019 for a description of how we determine fair value. RMBS, CMBS and GSE CRT collateral pledged is included in mortgage-backed and credit risk transfer securities on our condensed consolidated balance sheets. Loan participation interest collateral pledged was included in other assets on our condensed consolidated balance sheets. Cash collateral pledged on secured loans, 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 was classified as due from counterparties on our condensed consolidated balance sheets.

Agency CMBS purchase commitments that are recorded as mortgage-backed and credit risk transfer securities on our condensed consolidated balance sheets cannot be pledged as collateral until these securities settle. We held approximately $96.2 million of these securities as of December 31, 2019. We did not have any Agency CMBS purchase commitments as of June 30, 2020.

Cash collateral held on repurchase agreements 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, 2020 and December 31, 2019, 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 or fund margin calls if the value of pledged assets declined.

Our repurchase agreement collateral pledged ratio (MBS, GSE CRTs and a loan participation interest pledged as collateral/amount outstanding) was 109% as of December 31, 2019. We did not have any repurchase agreements as of June 30, 2020.

Secured Loans

Collateral pledged with the FHLBI is held in trust for the benefit of the FHLBI and is not commingled with our other assets. The FHLBI does not have the right to resell or repledge collateral posted unless an event of default occurs. The FHLBI retains the right to mark the underlying collateral for FHLBI advances to fair value as determined by the FHLBI in its sole discretion. IAS Services LLC would be required to provide additional collateral to meet margin calls if the value of pledged assets declines. See Note 6 - "Borrowings" for a discussion of the status of our FHLBI secured loans.

Interest Rate Swaps

All of the interest rate swaps that we have entered into during 2020 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 consolidated statements of operations. Our FCM agreements include cross default provisions. We were not a party to any interest rate swaps as of June 30, 2020.

Currency Forward Contracts

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

Note 8 – Derivatives and Hedging Activities

The following table summarizes changes in the notional amount of our derivative instruments during 2020:

$ in thousands	Notional Amount as of December 31, 2019	Additions	Settlement, Termination, Expiration or Exercise	Notional Amount as of June 30, 2020
Interest Rate Swaps	14,000,000	92,175,000	(106,175,000)	—

Total	14,488,077	92,220,674	(106,600,895)	107,856

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. In addition, our secured loans have floating interest rates. As such, we are exposed to changing interest rates. 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. Interest rate swaps involve making fixed-rate payments to a counterparty in exchange for the receipt of variable-rate amounts over the life of the agreements without exchange of the underlying notional amount.

20

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 $4.5 million and $14.6 million as a decrease (June 30, 2019: $5.9 million and $11.8 million as a decrease) to interest expense for the three and six months ended June 30, 2020, 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 is probable that the original forecasted repurchase agreement transactions will not occur by the end of the originally specified time period. During the next 12 months, we estimate that $20.0 million will be reclassified as a decrease to interest expense, repurchase agreements. As of June 30, 2020, $61.3 million (December 31, 2019: $75.9 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.

We did not have any interest rate swaps outstanding as of June 30, 2020. As of December 31, 2019, we had interest rate swaps with the following maturities outstanding:

$ in thousands	As of December 31, 2019
Maturities	Notional Amount(1)	Weighted Average Fixed Pay Rate		Weighted Average Receive Rate		Weighted Average Years to Maturity
2020	1,900,000	1.67	%	1.84	%	0.6

Total	14,000,000	1.47	%	1.79	%	5.2

(1)Notional amount includes $10.7 billion of interest rate swaps that received variable payments based on 1-month LIBOR and $3.3 billion of interest rate swaps that received variable payments based on 3-month LIBOR as of December 31, 2019.

Futures and Currency Forward Contracts

We purchase or sell U.S. Treasury futures contracts to help mitigate the potential impact of changes in interest rates on the performance of our investment portfolio. We recognize realized and unrealized gains and losses associated with the purchases or sales U.S. Treasury futures contracts in gain (loss) on derivative instruments, net in our condensed consolidated statements of operations. We did not have any futures contract outstanding as of June 30, 2020 and December 31, 2019.

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, 2020, we had $22.9 million (December 31, 2019: $23.1 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 are accounted for as hybrid financial instruments consisting of a debt host contract and an embedded credit derivative. Embedded derivatives associated with GSE CRTs are recorded within mortgage-backed and credit risk transfer securities, at fair value, on the condensed consolidated balance sheets. At June 30, 2020 and December 31, 2019, terms of the GSE CRT embedded derivatives are:

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, 2020 and December 31, 2019. The daily variation margin payment for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral. Our derivative asset of $18.5 million as of December 31, 2019 related to centrally cleared interest rate swaps is not included in the table below as a result of this characterization of daily variation margin.

As of June 30, 2020

(1)Amounts represent collateral pledged that is available to be offset against liability balances associated with currency forward contracts.

(2)The fair value of securities pledged as initial margin against our centrally cleared swaps was $189.8 million as of December 31, 2019. Cash collateral pledged on our currency forward contracts and centrally cleared interest rate swaps was $480,000 and $116.4 million as of June 30, 2020 and December 31, 2019, respectively. 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 $160,000 at December 31, 2019.

(3)The fair value of securities pledged against IAS Services LLC's borrowings under secured loans was $1.1 billion and $1.9 billion at June 30, 2020 and December 31, 2019, respectively. We pledged cash collateral against secured loans of $929,000 and $600,000 as of June 30, 2020 and December 31, 2019, respectively.

(4)The fair value of securities pledged against our borrowing under repurchase agreements was $19.1 billion at December 31, 2019. We pledged cash collateral of $32.6 million and held cash collateral of $10,000 under repurchase agreements as of December 31, 2019.

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.

(1)For more detail about the fair value of our MBS and GSE CRTs, refer to Note 4 - "Mortgage-Backed and Credit Risk Transfer Securities."

(2)Our GSE CRTs purchased prior to August 24, 2015 are accounted for as hybrid financial instruments with an embedded derivative. The hybrid financial instruments consist of debt host contracts classified as Level 2 and embedded derivatives classified as Level 3. As of June 30, 2020, the net embedded derivative liability position of $17.2 million includes $100,000 of embedded derivatives in an asset position and $17.3 million of embedded derivatives in a liability position. As of December 31, 2019, the net embedded derivative asset position of $10.3 million includes $19.5 million of embedded derivatives in an asset position and $9.2 million of embedded derivatives in a liability position.

(3)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, 2020 and December 31, 2019, the weighted average remaining term of our investments in unconsolidated ventures was 1.9 years and 2.2 years, respectively.

(4)Includes $44.7 million of a loan participation interest as of December 31, 2019 and $21.8 million of a commercial loan as of June 30, 2020. We elected the fair value option for our commercial loan as of January 1, 2020 and valued the loan based on a third party appraisal as of June 30, 2020. We sold the loan participation interest on April 1, 2020.

The following tables summarize significant unobservable inputs used in the fair value measurement of our GSE CRT embedded derivatives:

	Fair Value at	Valuation	Unobservable		Weighted
$ in thousands	June 30, 2020	Technique	Input	Range	Average
GSE CRT Embedded Derivatives	(17,223)	Market Comparables, Vendor Pricing	Weighted average life	1.9 - 2.8 years	2.2 years

$ in thousands	December 31, 2019	Technique	Input	Range	Average
GSE CRT Embedded Derivatives	10,281	Market Comparables, Vendor Pricing	Weighted average life	1.1 - 4.2 years	2.9 years

These significant unobservable inputs change according to market conditions and security performance. We estimate the weighted average life of GSE CRTs in order to identify GSE corporate debt with a similar maturity. We obtain our weighted average life estimates from a third party provider. Although weighted average life is a significant input, changes in weighted average life may not have an explicit directional impact on the fair value measurement.

The following table summarizes the significant unobservable input used in the fair value measurement of our commercial loan:

(1)We elected the fair value option for our commercial loan on January 1, 2020.

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 our commercial loan, held-for-investment, included in "Other assets" on our condensed consolidated balance sheet as of December 31, 2019, is a Level 3 fair value measurement. The fair value was determined by an independent pricing service using a discounted cash flow analysis.

•The estimated fair value of FHLBI stock, included in "Other assets" on our condensed consolidated balance sheets, is a Level 3 fair value measurement. FHLBI stock may only be sold back to the FHLBI at its discretion at par. As a result, the cost of the FHLBI stock approximates its fair value.

•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.

•The estimated fair value of secured loans is a Level 3 fair value measurement. As of June 30, 2020, the secured loans have variable rates based on the FHLBI's short-term cost of funds. As of December 31, 2020, the secured loans had floating rates based on an index plus a spread and the spread was typically consistent with those demanded in the

27

market. Accordingly, the interest rates on these secured loans are at market, and thus the carrying amount approximates fair value.

Note 11 – Related Party Transactions

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, 2020, we reimbursed our Manager $242,000 and $484,000 (June 30, 2019: $213,000 and $396,000), respectively, for costs of support personnel.

We have invested $1.4 million as of June 30, 2020 (December 31, 2019: $154.0 million) in money market or mutual funds managed by affiliates of our Manager. 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.

Management Fee Expense

Effective October 1, 2019, 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, 2020 and 2019.

On May 9, 2020, our board of directors approved payment of our common stock dividend that was declared on March 17, 2020 in a combination of cash and shares of our common stock. 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.

Executive Summary

We are a Maryland corporation primarily focused on investing in, financing and managing residential and commercial mortgage-backed securities ("MBS") and mortgage loans. Our objective is to provide attractive risk-adjusted returns to our investors, primarily through dividends and secondarily through capital appreciation. To achieve this objective, we have historically invested 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");

35

•Commercial mortgage-backed securities ("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");

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

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

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

•Residential and commercial mortgage loans; and

•Other real estate-related financing arrangements.

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 definition of "Investment Company" under the 1940 Act. We are externally managed and advised by Invesco Advisers, Inc., our Manager, which is an indirect, wholly-owned subsidiary of Invesco Ltd.

During the six months ended June 30, 2020, we experienced unprecedented market conditions as a result of the COVID-19 pandemic. Due to significant spread widening in both Agency and non-Agency securities, we received an unusually high number of margin calls from counterparties. On March 23, 2020, we notified our financing counterparties that we were not in a position to fund the margin calls we received on March 23, 2020, and that we did not expect to be in a position to fund the anticipated volume of future margin calls under our financing arrangements in the near term as a result of market disruptions created by the COVID-19 pandemic. We engaged third party financial and legal advisors to assist us in restructuring our debt with our financing counterparties. To generate liquidity and reduce leverage, we sold MBS and GSE CRTs for cash proceeds of $23.1 billion and repaid $17.5 billion of our repurchase agreements and $910.0 million of our secured loans with proceeds from these asset sales and the return of cash margin previously pledged on our repurchase agreements during the six months ended June 30, 2020. As of June 30, 2020, our total borrowings consist of $740.0 million of secured loans that are due by December 2020. We intend to repay our secured loans with proceeds from sales of non-Agency CMBS assets that are currently collateralizing these loans. We repaid an additional $435.0 million of our secured loans in July 2020.

Invesco, including our Manager, is committed to helping its employees, clients and communities navigate the challenges presented by the spread of COVID-19. The primary focus of Invesco's efforts is to ensure the health and safety of its employees while preserving its ability to serve clients and manage assets in a highly dynamic market environment. To help ensure it can continue to meet client needs, such as those of our Company, a significant number of our Manager’s employees are working remotely, with small select teams working at alternate sites or operating in split shifts to mitigate the risks associated with the virus. Portfolio managers, research analysts and traders are successfully working remotely or in secure locations with access to all systems necessary to fulfill their responsibilities and an ability to connect with their teams in managing client assets. Additionally, our Manager’s operational, control and support teams have successfully transitioned to a remote working environment.

In July 2020, we resumed investing in Agency securities and financed these securities with repurchase agreement borrowings. As of July 31, 2020, we have a total investment portfolio, excluding cash, of approximately $3.3 billion consisting of 68% of Agency RMBS, 30% commercial credit investments and 2% residential credit investments. Approximately $473 million of our investment portfolio is unencumbered. As of July 31, 2020, we have a cash balance of $230.3 million, approximately $89.5 million of which is posted as collateral for derivatives and our remaining secured loans. Our total debt consisted of $2.1 billion of repurchase agreement borrowings that are collateralized by Agency RMBS and $305.0 million of secured loans that are collateralized by non-Agency CMBS and cash as of July 31, 2020.

We continue to evaluate potential credit investments that do not rely on short-term or mark-to-market financing. To further strengthen our balance sheet and position ourselves for future investment opportunities, we have explored and will continue to explore additional sources of financing including issuances of debt and equity securities and other forms of long-term financing arrangements. However, no assurance can be given that we will be able to access any additional sources of financing.

We paid our first quarter 2020 common stock dividend of $0.50 per share on June 30, 2020 in a combination of cash and common shares. In addition, on June 17, 2020, we declared a second quarter 2020 common stock cash dividend of $0.02 per common share that was paid in cash on July 28, 2020. Dividends on our Series A Preferred, Series B Preferred and Series C Preferred Stock are current.

Market Conditions

Macroeconomic factors that affect our business include interest rate spread premiums, governmental 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 rebounded sharply during the second quarter of 2020 as equities and most credit sectors reacted favorably to the massive government action taken in response to the COVID-19 pandemic as well as the re-opening of parts of the economy. This rebound can be seen across a number of economic measures, as economic activity picked up after an unprecedented drop during the first quarter. For example, nonfarm payrolls, retail sales and consumer confidence data showed record drops during March and April, followed by record recoveries during May and June. While the increase in economic activity is encouraging, we remain cautious about the pace of future gains as COVID-19 case numbers continue to grow in the U.S., and some states are re-instituting partial economic shutdowns.

Interest rates were little changed during the quarter, with the yield on the 2 year Treasury note falling 10 basis points to 0.15% and the yield on the 10 year Treasury bond falling a basis point to 0.66%. The short end of the yield curve remains pinned close to zero, as the Federal Funds target rate is at the lower bound, and the futures market is forecasting no change for the next several years. Interest rate volatility measures also reflect the view that rates will remain low, as these have fallen to multi-year lows. Price data has been subdued, as both the consumer price index (0.1% in May) and price consumption expenditure index (1.0% in May) measures have fallen over the past several months. Breakeven rates on inflation protected Treasuries reflect low expectations for inflation, as the inflation rate implied by 2 year and 5 year TIPs was 0.88% and 1.17%, respectively, at quarter end.

Most risk markets have rallied off of the March lows. Equity markets showed remarkable resilience despite continued economic uncertainty, as the S&P 500 was up 20% during the second quarter after dropping 20% during the first quarter. The NASDAQ index fared even better, as it returned 30.6% during the second quarter after dropping 14.2% during the first quarter. The broader credit markets also rallied during the quarter, buoyed by support from the Federal Reserve. In particular, spreads on investment grade and high yield corporate credits have tightened notably during the quarter as those sectors have received direct support from the Federal Reserve.

Covid-19 has negatively impacted commercial real estate fundamentals. The lodging and retail sectors have been the most impacted due to travel restrictions and a slowdown in discretionary consumption. In the retail sector, despite long-term leases, tenants that are not open for business are finding it difficult to meet rent obligations and, in some instances, are foregoing payments or seeking forbearance relief. Real estate loans are experiencing growing delinquencies and are at greater risk of default which could impact the fundamental performance of our investments. Despite fundamental deterioration, CMBS risk premiums contracted in the second quarter due to relatively minimal new issuance supply and increased investor demand. The United States Federal Reserve’s Term Asset-Backed Securities Loan Facility (TALF), which provides financing for triple-A rated conduit non-Agency CMBS, has also helped provide stability to the CMBS market. We believe TALF, along with slowly renewed economic activity, will continue to assist in creating renewed investor interest in CMBS.

While there has been a partial recovery in residential mortgage credit spreads, particularly in higher rated securities, valuations continue to reflect an uncertain outlook for borrowers, and the sector has not benefited from direct support from the Federal Reserve. The U.S. Congress responded to the COVID-19 pandemic by passing three rounds of fiscal stimulus measures, the most notable being the $2.2 trillion Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), which included relief measures for households and businesses directly or indirectly impacted by the virus. The CARES Act includes provisions for COVID-19 related temporary forbearance on federally backed mortgage loans, which allows borrowers of loans guaranteed by Fannie Mae, Freddie Mac and Ginnie Mae to suspend making principal and interest payments for a period of up to 360 days if they are facing hardship. Following the temporary forbearance period, mortgage servicers must provide several options to impacted borrowers, including a repayment schedule or loan modification, depending on the borrowers’ circumstances. We believe the provision of forbearance and loan modifications will substantially reduce borrower defaults and loan losses relative to levels that would have likely occurred without these actions.

The performance of Agency RMBS was strong during the second quarter as that sector benefited directly from unprecedented purchases by the Federal Reserve. Spreads on Agency RMBS and pay-ups on specified pool collateral have completely recovered from their March lows despite an uptick in prepayment risk due to lower rates. We expect the market for Agency RMBS to continue to be constructive as the level of support from the Federal Reserve remains strong.

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

37

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.

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. 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, and it is possible that not all of our assets and liabilities will transition 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. Industry organizations are attempting to structure the spread calculation in an objective manner, but there is no assurance that all asset types or securitization vehicles will use the same spread. We and other market participants have less experience understanding and modeling SOFR-based assets and liabilities than LIBOR-based assets and liabilities, increasing the difficulty of investing, hedging, and risk management.

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.

Our Manager is finalizing its global assessment of exposure in relation to our LIBOR-based instruments and benchmarks and is prioritizing the mitigation of risks associated with the forecasted changes to financial instruments and performance benchmarks referencing existing LIBOR rates.

In October 2019, the IRS and Treasury proposed regulations that are expected to provide taxpayers relief from adverse impacts resulting from the transition away from LIBOR to an alternative reference rate. The proposed regulations make clear that a change in the reference rate (and associated alterations to payment terms) of a financial instrument is generally not considered a taxable event, provided the fair value of the modified instrument is substantially equivalent to the fair value of the unmodified instrument.

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 is effective for all entities as of March 12, 2020 through December 31, 2022.

Investment Activities

As previously discussed, the COVID-19 pandemic caused unprecedented market disruption in the six months ended June 30, 2020. To raise liquidity and reduce leverage, we sold MBS and GSE CRTs for cash proceeds of $23.1 billion.

The table below shows the breakdown of our investment portfolio as of June 30, 2020, December 31, 2019 and June 30, 2019:

	As of
$ in thousands	June 30, 2020	December 31, 2019	June 30, 2019
Agency RMBS:
30 year fixed-rate, at fair value	6,828	10,524,220	12,077,091

Non-Agency RMBS, at fair value	14,404	955,671	1,118,073
GSE CRT, at fair value	101,886	923,672	904,844

Investments in unconsolidated ventures	19,246	21,998	25,675
Total investment portfolio	1,625,196	21,862,493	21,633,928

As of June 30, 2020, our holdings of 30-year fixed-rate Agency RMBS represented less than 1% of our total investment portfolio versus 48% as of December 31, 2019 and 56% as of June 30, 2019. We historically focused our purchases of 30 year fixed-rate Agency RMBS on specified pools priced at modest pay-ups to generic Agency RMBS because those securities have characteristics that reduce prepayment risk. We resumed investing in 30-year fixed-rate Agency RMBS in July 2020.

As of June 30, 2020, we sold all of our holdings of Agency CMBS. Agency CMBS represented approximately 22% of our holdings as of December 31, 2019 and 14% of our holdings as of June 30, 2019. We historically focused our Agency CMBS investments in securities issued by Freddie Mac, Fannie Mae and Ginnie Mae that have characteristics that reduce prepayment risk.

Our investments that have credit exposure include non-Agency CMBS, non-Agency RMBS, GSE CRTs and a commercial real estate loan. Rather than relying on the rating agencies, we utilize proprietary models as well as third party applications to quantify and monitor the credit risk associated with these holdings. Our analysis generally begins at the underlying asset level, where we gather detailed information on loan, borrower, and property characteristics that inform our expectations for future performance. In addition to base case cash flow projections, we perform a range of scenario stresses to gauge the sensitivity of returns to potential deviations in underlying asset behavior. We perform this detailed credit analysis at the time of initial purchase and regularly throughout the holding period of each investment.

As of June 30, 2020, our holdings of non-Agency CMBS represented approximately 90% of our total investment portfolio versus 17% as of December 31, 2019 and 17% as of June 30, 2019. 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, Florida and Illinois as detailed in the tables below. The majority of our non-Agency CMBS portfolio is comprised of fixed rate credits that are rated investment grade by a nationally recognized statistical rating organization. Approximately 87% of non-Agency CMBS are rated single-A (or equivalent) or higher by a nationally recognized statistical rating organization as of June 30, 2020. Further, approximately 74% of non-Agency CMBS are rated double-A (or equivalent) or higher by a nationally recognized statistical rating organization as of June 30, 2020.

As of June 30, 2020, our holdings of non-Agency RMBS represented approximately 1% of our total investment portfolio versus 4% as of December 31, 2019 and 5% as of June 30, 2019. We primarily hold non-Agency RMBS securities collateralized by prime and Alt-A loans. In addition, we have invested in re-securitizations of real estate mortgage investment

39

conduit ("Re-REMIC") RMBS and securitizations of reperforming mortgage loans that we expect to provide attractive risk adjusted returns.

As of June 30, 2020, our holdings of GSE CRTs represented approximately 6% of our total investment portfolio versus 4% as of December 31, 2019 and 4% as of June 30, 2019. 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. The majority of our GSE CRT holdings are concentrated in 2013 and 2014 vintages, where reference loans have significant embedded home price appreciation. GSE CRTs have the added benefit of paying a floating rate coupon that reduces our need to hedge interest rate risk.

As of June 30, 2020, we held an investment in one commercial real estate mezzanine loan that matures in 2021 and has a loan-to-value ratio of approximately 68.3%.

As of June 30, 2020, we held investments in two unconsolidated ventures that are managed by an affiliate of our Manager. The unconsolidated ventures invest in our target assets. We are committed to invest $6.5 million in additional capital in these unconsolidated ventures to fund future investments and cover future expenses should they occur.

Financing and Other Liabilities

We have historically used repurchase agreements to finance the majority of our target assets and expect 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 repaid all of our repurchase agreements as of May 7, 2020 with proceeds from asset sales and the return of cash margin previously pledged on our repurchase agreements.

Our wholly-owned subsidiary, IAS Services LLC, is a member of the Federal Home Loan Bank of Indianapolis ("FHLBI") and has borrowed funds from the FHLBI in the form of secured loans. As of June 30, 2020, IAS Services LLC had $740.0 million in outstanding secured loans that are due by December 2020. As of July 31, 2020, we reduced the balance of our secured loans to $305.0 million. We intend to repay the remaining balance of our secured loans with proceeds from sales of assets collateralizing the secured loans by December 2020. As discussed in Note 5 - "Other Assets," IAS Services LLC is required to purchase and hold a certain amount of FHLBI stock, which is based, in part, upon the outstanding principal balance of secured loans from the FHLBI.

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

(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.

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 pay fixed interest rates and receive floating interest rates indexed off of one- or three-month LIBOR.

41

We actively manage our swap portfolio by terminating and entering into new swaps as the size and composition of our investment portfolio changes. We terminated all of our interest rate swaps in March 2020 as we positioned our portfolio in response to unprecedented market conditions associated with the COVID-19 pandemic. We did not enter into new swaps during the three months ended June 30, 2020 because our exposure to interest rate risk decreased as we sold Agency assets and repaid borrowings. We realized a net loss of $904.7 million on interest rate swaps during the six months ended June 30, 2020 primarily due to falling 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, 2020, we had €20.8 million or $22.9 million (December 31, 2019: €20.8 million or $23.1 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, 2020, we settled currency forward contracts of €41.7 million or $45.8 million (June 30, 2019:€42.6 million or $48.7 million) in notional amount and realized a net gain of $346,000 (June 30, 2019: $738,000 net gain).

Capital Activities

We may sell up to 17,000,000 shares of our common stock and 7,000,000 shares of our preferred stock from time to time in at-the-market or privately negotiated transactions under our equity distribution agreements. We did not sell any shares under these agreements during the six months ended June 30, 2020.

For information on dividends declared and paid during the six months ended June 30, 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, 2020, we did not repurchase any shares of our common stock.

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, 2020 and 2019. 

	Three months ended June 30,				Six Months Ended June 30,
$ in thousands	2020		2019		2020		2019

Average earning asset yields (2)	6.33	%	3.89	%	4.39	%	3.90	%

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

(2)Average earning asset yields for the period were calculated by dividing interest income, including amortization of premiums and discounts, by the average month-end 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 $1.9 billion for the three months ended June 30, 2020 (June 30, 2019: $20.8 billion) and $9.9 billion for the six months ended June 30, 2020 (June 30, 2019: $20.0 billion). Average earning assets decreased for the three and six months ended June 30, 2020 primarily due to the sale of MBS and GSE CRTs for cash proceeds of $6.9 billion and $23.1 billion in the three and six months ended June 30, 2020, respectively. Due to the magnitude of the reduction in our investment portfolio since December 31, 2019, our average earning assets and asset yields for the three and six months ended June 30, 2020 are not indicative of our future ability to generate interest income.

We earned total interest income of $30.2 million and $216.9 million (June 30, 2019: $202.2 million and $389.3 million) for the three and six months ended June 30, 2020, respectively. 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	2020	2019	2020	2019
Interest Income
MBS and GSE CRT - coupon interest	26,841	214,501	228,950	406,943
MBS and GSE CRT - net premium amortization	2,787	(13,764)	(13,786)	(20,714)
MBS and GSE CRT - interest income	29,628	200,737	215,164	386,229
Commercial and other loans	545	1,484	1,708	3,066
Total interest income	30,173	202,221	216,872	389,295

MBS and GSE CRT interest income decreased $171.1 million in both the three and six months ended June 30, 2020, compared to the same periods in 2019 primarily due to a $187.7 million and $178.0 million decrease in coupon interest reflecting lower average earning assets. Lower coupon interest was offset by a $16.6 million and $6.9 million decrease in net premium amortization during the three and six months ended June 30, 2020, respectively, due to sales of assets purchased at premiums.

Interest income on our commercial and other loans decreased $939,000 and $1.4 million during the three and six months ended June 30, 2020, respectively, due to the sale of our loan participation interest in April 2020 and principal payments on commercial loans totaling $7.3 million in the six months ended June 30, 2019.

Prepayment Speeds

Our RMBS and 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 on our RMBS and GSE CRT portfolio 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. The standard measure of prepayment speeds is the constant prepayment rate, also known as the conditional prepayment rate or "CPR". The table below provides the three month constant prepayment rate for our RMBS and GSE CRTs as of June 30, 2020, December 31, 2019, and June 30, 2019.

	As of
	June 30, 2020	December 31, 2019	June 30, 2019
15 year fixed-rate Agency RMBS	7.4	12.5	11.1
30 year fixed-rate Agency RMBS	8.0	18.1	8.5

Net premium amortization decreased $16.6 million and $6.9 million for the three and six months ended June 30, 2020, respectively, compared to the same periods in 2019 primarily due to sales of assets purchased at premiums.

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, 2020 and 2019:

	Three months ended June 30,		Six Months Ended June 30,
$ in thousands	2020	2019	2020	2019
Interest Expense
Interest expense on repurchase agreement borrowings	3,233	123,894	92,342	231,620
Amortization of net deferred (gain) loss on de-designated interest rate swaps	(4,503)	(5,916)	(14,570)	(11,767)
Repurchase agreements interest expense	(1,270)	117,978	77,772	219,853
Secured loans	1,712	11,258	8,358	22,402
Total interest expense	442	129,236	86,130	242,255

We have historically entered into repurchase agreements to finance the majority of our target assets. These agreements are secured by our mortgage-backed and credit risk transfer securities. These 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. At each settlement date, we typically refinance each repurchase agreement at the market interest rate at that time.

Our interest expense on repurchase agreement borrowings decreased $120.7 million and $139.3 million for the three and six months ended June 30, 2020, respectively, compared to 2019 due to lower average borrowings and a lower average cost of funds reflecting decreases in the Federal Funds interest rate. Average borrowings decreased primarily due to repayment of $17.5 billion of repurchase agreements with proceeds from asset sales due to financial market disruption caused by the COVID-19 pandemic as previously discussed in this Management's Discussion and Analysis of Financial Condition and Results of Operations. Average borrowings also decreased due to repayment of $910.0 million of secured loans during the six months ended June 30, 2020.

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 $4.5 million and $14.6 million during the three and six months ended June 30, 2020, respectively, and $5.9 million and $11.8 million during the three and six months ended June 30, 2019, 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 six months ended June 30, 2020 by $2.7 million because it is probable the original forecasted transactions will not occur by the end of the originally specified time period. During the next twelve months, we estimate that $20.0 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.

45

During the three and six months ended June 30, 2020, interest expense for our secured loans decreased $9.5 million and $14.0 million, respectively, compared to the same periods in 2019 due to repayment of $910.0 million of secured loans during the six months ended June 30, 2020 and lower borrowing rates. Borrowing rates on our secured loans are based on FHLBI's short-term cost of funds. 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%, as compared to 2.73% and 2.72% for the three and six months ended June 30, 2019, respectively.

Our total interest expense during the three and six months ended June 30, 2020 decreased $128.8 million and $156.1 million, respectively, from the same periods in 2019 primarily due to the $130.2 million and $153.3 million decrease in interest expense on repurchase agreements borrowings and secured loans in the 2020 periods 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, 2020 and 2019:

	Three months ended June 30,				Six Months Ended June 30,
$ in thousands	2020		2019		2020		2019
Total average borrowings (1)	981,992		18,908,927		8,756,995		17,983,666
Maximum borrowings during the period (2)	1,373,296		19,365,413		23,132,234		19,365,413
Cost of funds (3)	0.18	%	2.73	%	1.97	%	2.69	%

(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 excluding amortization of net deferred gain (loss) on de-designated interest rate swaps by our average borrowings. All percentages are annualized.

Total average borrowings decreased $17.9 billion and $9.2 billion in the three and six months ended June 30, 2020, respectively, compared to 2019 primarily because we repaid $17.5 billion of repurchase agreements and $910.0 million of secured loans during the six months ended June 30, 2020 as discussed above. Our average cost of funds decreased 255 basis points and 72 basis points for three and six months ended June 30, 2020, respectively, versus 2019 primarily due to decreases in the Federal Funds rate over the past twelve months.

Our average borrowings for the three and six months ended June 30, 2020 are not indicative of our future interest expense because we repaid $17.5 billion of repurchase agreements and $910.0 million of secured loans during the six months ended June 30, 2020.

Net Interest Income

The table below presents the components of net interest income for the three and six months ended June 30, 2020 and 2019:

Total interest expense	442		129,236		86,130		242,255
Net interest income	29,731		72,985		130,742		147,040
Net interest rate margin	6.15	%	1.16	%	2.42	%	1.21	%

Our net interest income, which equals interest income less interest expense, totaled $29.7 million and $130.7 million (June 30, 2019: $73.0 million and $147.0 million) for the three and six months ended June 30, 2020, respectively. The decrease

46

in net interest income for the three and six months ended June 30, 2020 was primarily due the sale of MBS and GSE CRTs to generate liquidity and reduce leverage 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 6.15% and 2.42% (June 30, 2019: 1.16% and 1.21%) for the three and six months ended June 30, 2020, respectively. The increase in net interest rate margin for the three and six months ended June 30, 2020 compared to the same periods in 2019 was primarily due to the change in our portfolio composition due to assets sales and decreases in the Federal Funds rate throughout 2019 that had a greater impact on our average cost of funds than on our average earning asset yields. Our cost of funds on all of our borrowings is influenced by changes in short-term interest rates, whereas approximately 92% of the Company’s investments were fixed rate assets as of June 30, 2020.

As previously discussed, we experienced unprecedented market conditions as a result of the COVID-19 pandemic during the six months ended June 30, 2020. To generate liquidity and reduce leverage, we sold MBS and GSE CRTs for cash proceeds of $23.1 billion (June 30, 2019: $1.7 billion) and realized net losses of $409.0 million (June 30, 2019: net losses of $9.1 million). Sales prices of our holdings were severely impacted by the lack of liquidity and uncertainty surrounding the economic impact of 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 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 these securities before recovery of their amortized cost basis. We assess our investment securities for credit losses and impairment on a quarterly basis. For additional information regarding our accounting policy for credit losses and impairment, refer to Note 2 – “Summary of Significant Accounting Policies” of our condensed consolidated financial statements included in Part I. Item 1. of this Quarterly Report.

We have elected the fair value option for all of our RMBS interest-only securities, our MBS purchased on or after September 1, 2016 and our GSE CRTs purchased on or after August 24, 2015. 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, 2020, $230.9 million (December 31, 2019: $17.4 billion) or 15% (December 31, 2019: 80%) of our MBS and GSE CRT are accounted for under the fair value option. Our percentage of MBS and GSE CRTs accounted for under the fair value option declined as of June 30, 2020 due to sales of securities accounted for under the fair value option during the six months ended June 30, 2020.

We recorded net unrealized losses on our MBS portfolio accounted for under the fair value option of $34.5 million and $549.0 million in the three and six months ended June 30, 2020, respectively, compared to net unrealized gains of $304.7 million and $584.7 million in the three and six months ended June 30, 2019, respectively. Net unrealized losses in the three and six months ended June 30, 2020 reflect lower interest rates and wider interest rate spreads on our Agency and non-Agency

assets. We also recorded net unrealized gains on our GSE CRT portfolio accounted for under the fair value option of $139.9 million and $12.4 million net unrealized losses in the three and six months ended June 30, 2020, respectively, compared to net unrealized losses of $3.3 million and $2.1 million in the three and six months ended June 30, 2019, respectively. Net unrealized losses in the six months ended June 30, 2020 reflect declines in valuations due to wider interest rate spreads.

We recorded a realized loss of $3.8 million on our loan participation interest during the three and six months ended June 30, 2020 and unrealized losses of $785,000 and $2.5 million on our commercial loan during the three and six months ended June 30, 2020, respectively. We sold the loan participation interest on April 1, 2020. We valued our commercial loan based upon a valuation from an independent pricing service.

Equity in Earnings (Losses) of Unconsolidated Ventures

For the three and six months ended June 30, 2020, we recorded equity in earnings of unconsolidated ventures of $318,000 and $488,000 (June 30, 2019: equity in earnings of $702,000 and $1.4 million), respectively. We recorded equity in earnings for the three and six months ended June 30, 2020 and 2019 primarily due to realized and unrealized gains on the underlying portfolio investments.

Gain (Loss) on Derivative Instruments, net

Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements on our floating rate repurchase agreements and secured loans. To accomplish these objectives, we primarily use interest rate derivative instruments, including interest rate swaps and U.S. Treasury futures contracts as part of our interest rate risk management strategy.

We also use currency forward contracts to help mitigate the potential impact of changes in foreign currency exchange rates on our unconsolidated joint venture investment denominated in Euros.

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, 2020, we terminated existing swaps with a notional amount of $106.2 billion and entered into new swaps with a notional amount of $92.2 billion to hedge repurchase agreement debt associated with purchases of Agency RMBS and Agency CMBS securities. We terminated all outstanding interest rate swaps in March 2020 as we positioned our portfolio in response to unprecedented market conditions associated with the COVID-19 pandemic and did not have any swaps outstanding as of June 30, 2020. Our exposure to interest rate risk decreased as we sold Agency assets and repaid borrowings. We realized a net loss of $904.7 million on the termination of interest rate swaps during the six months ended June 30, 2020 primarily due to falling interest rates.

As of December 31, 2019, we held the following interest rate swaps whereby we receive interest at a one-month and three-month LIBOR rate:

$ in thousands	As of December 31, 2019
Derivative instrument	Notional Amounts	Average Fixed Pay Rate		Average Receive Rate		Average Maturity (Years)
Interest Rate Swaps	14,000,000	1.47	%	1.79	%	5.2

We were not a party to any futures contracts during the six months ended June 30, 2020. During the six months ended June 30, 2019, we settled futures contracts with a notional amount of $4.3 billion. We realized a net loss of $132.6 million on the settlement of futures contracts during the six months ended June 30, 2019 due to falling interest rates. Daily variation margin payment for futures 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.

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 and 2019.

	Three months ended June 30,		Six Months Ended June 30,
$ in thousands	2020	2019	2020	2019
GSE CRT embedded derivative coupon interest	1,127	5,300	5,845	10,650

Total realized and unrealized credit derivative income (loss), net	(2,738)	(2,438)	(35,790)	5,446

In the three and six months ended June 30, 2020, we recorded a decrease of $300,000 and $41.2 million in realized and unrealized credit derivative income (loss), net compared to the same periods in 2019. The decrease was primarily driven by a decline in the fair value of our GSE CRT embedded derivatives in the three and six months ended June 30, 2020 as asset prices declined due to spread widening.

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. 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 and 2019 primarily consists of quarterly dividends from FHLBI stock. We are required to purchase and hold a certain amount of FHLBI stock, which is based, in part, upon the outstanding principal balance of secured advances from the FHLBI. We earn dividend income on our investment in FHLBI stock, and the amount of our dividend income varies based upon the number of shares that we are required to own and the dividend declared per share.

Expenses

We incurred management fees of $9.8 million and $20.7 million (June 30, 2019: $9.4 million and $18.9 million) for the three and six months ended June 30, 2020, respectively. Management fees increased for the three and six months ended June 30, 2020 compared to the same period in 2019 due to a higher management fee base. Our management fees are calculated quarterly in arrears. Our management fee will be lower in the three months ended September 30, 2020 because our average month-end stockholders' equity decreased during the three months ended June 30, 2020 primarily due to realized losses on sales of investments. 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 $4.1 million and $7.2 million (June 30, 2019: $2.0 million and $4.3 million) for the three and six months ended June 30, 2020, respectively. 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 higher for the three and six months ended June 30, 2020 compared to the same periods in 2019 primarily due to fees paid for third-party legal and advisory services in connection with navigating market disruption associated with the COVID-19 pandemic totaling $1.5 million and $2.6 million, respectively.

Net Income (Loss) attributable to Common Stockholders

For the three months ended June 30, 2020, our net loss attributable to common stockholders was $299.9 million (June 30, 2019: $7.2 million net income attributable to common stockholders) or $1.80 basic and diluted net loss per average share available to common stockholders (June 30, 2019: $0.06 basic and diluted net income per average share available to common stockholders). The change in net income (loss) attributable to common stockholders was primarily due to (i) a net loss on derivative instruments of $343,000 in the 2020 period compared to a net loss on derivative instruments of $344.7 million in the 2019 period; (ii) a net loss on investments of $306.4 million in the 2020 period compared to a net gain on investments of $302.2 million in the 2019 period; and (iii) a $43.3 million decrease in net interest income.

For the six months ended June 30, 2020, our net loss attributable to common stockholders was $1.9 billion (June 30, 2019: $134.9 million net income attributable to common stockholders) or $11.91 basic and diluted net loss per average share available to common stockholders (June 30, 2019: $1.08 basic and diluted net income per average share available to common stockholders). The change in net income (loss) attributable to common stockholders was primarily due to (i) a net loss on derivative instruments of $911.1 million in the 2020 period compared to a net loss on derivative instruments of $546.2 million in the 2019 period; (ii) a net loss on investments of $1.1 billion in the 2020 period compared to a net gain on investments of $570.6 million in the 2019 period; (iii) a credit derivative net loss of $35.8 million in the 2020 period compared to credit derivative net income of $5.4 million in the 2019 period; and (iv) a $16.3 million decrease in net interest income.

For further information on the changes in net gain (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 have historically used 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:

•core earnings (and by calculation, core earnings 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

•repurchase agreement 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. 

We are not presenting core earnings for the three and six months ended June 30, 2020 because core earnings excludes the material adverse impact that the market disruption caused by the COVID-19 pandemic has had on our financial condition. In addition, core earnings for the three and six months ended June 30, 2020 are not indicative of the reduced earnings potential of our current investment portfolio. We intend to resume reporting core earnings when its presentation provides a useful measure of our portfolio’s earning capacity.

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.

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

We calculate effective interest income (and by calculation, effective yield) as U.S. GAAP total interest income adjusted for GSE CRT embedded derivative coupon interest that is recorded as realized and unrealized credit derivative income (loss), net. We include our GSE CRT embedded derivative coupon interest in effective interest income because GSE CRT coupon interest is not accounted for consistently under U.S. GAAP. We account for GSE CRTs purchased prior to August 24, 2015 as hybrid financial instruments, but we have 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 is recorded as realized and unrealized credit derivative income (loss). We add back GSE CRT embedded derivative coupon interest to our total interest income because we consider 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, amortization of net deferred gains (losses) on de-designated interest rate swaps that is recorded as

51

repurchase agreements interest expense and GSE CRT embedded derivative coupon interest that is 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, provide information that is useful to investors in understanding our borrowing costs and operating performance.

The following tables reconcile total interest income to effective interest income and yield to effective yield for the following periods:

	Three months ended June 30,

Effective interest income	222,717	4.51	%	399,945	4.00	%

Our effective interest income decreased $176.2 million and $177.2 million in the three and six months ended June 30, 2020, respectively, versus the same period in 2019 due to lower average earning assets. Our average earning assets decreased to $1.9 billion and $9.9 billion from $20.8 billion and $20.0 billion for three and six months ended June 30, 2020, respectively, primarily because we sold MBS and GSE CRT or cash proceeds of $23.1 billion during the six months ended June 30, 2020 due to disruption in the financial markets caused by the COVID-19 pandemic as previously discussed.

Our effective interest expense and effective cost of funds decreased during the three and six months ended June 30, 2020 compared to the same period in 2019 primarily due to lower interest expense paid on our repurchase agreements. We paid interest expense of $442,000 and $86.1 million during the three and six months ended June 30, 2020, respectively, compared to $129.2 million and $242.3 million for the same periods in 2019, respectively, due to lower average borrowings and a lower Federal Funds target interest rate.

Effective net interest income	133,941	2.48	%	157,957	1.31	%

Effective net interest income decreased during the three and six months ended June 30, 2020 compared to the same periods in 2019 primarily due to lower average earning asset balances that were partially offset by lower average borrowings and a lower effective cost of funds driven by cuts in the Federal Funds interest rate.

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.

The COVID-19 pandemic-driven disruptions in the real estate, mortgage and financial markets have negatively affected and are expected to continue to negatively affect our liquidity. Under the terms of our repurchase agreements and secured loans, 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. Additionally, our lenders raised required haircuts on our collateral for new repurchase agreements, driving further liquidity needs. We sold portfolio assets in order to generate liquidity, in many cases at significantly distressed market prices. These events have led us to seek to maintain higher levels of cash and unencumbered assets. See Part I. Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations and Part II. Other Information - Item 1A. Risk Factors in this Quarterly Report for more information on how the COVID-19 pandemic has impacted and may continue to impact our liquidity and capital resources.

We held cash, cash equivalents and restricted cash of $271.6 million at June 30, 2020 (June 30, 2019: $154.9 million). As previously discussed, we increased our cash, cash equivalents and restricted cash balances at June 30, 2020 to improve our liquidity in light of market disruption created by the COVID-19 pandemic. Our operating activities provided net cash of $130.6 million for the six months ended June 30, 2020 (June 30, 2019: $157.0 million).

Our investing activities provided net cash of $18.0 billion in the six months ended June 30, 2020 compared to net cash used by investing activities of $3.7 billion in the six months ended June 30, 2019. Our primary source of cash from investing activities for the six months ended June 30, 2020 was proceeds from sales of MBS and GSE CRTs of $23.1 billion (June 30, 2019: $1.7 billion) to improve liquidity. We also generated $690.1 million from principal payments of MBS and GSE CRTs during the six months ended June 30, 2020 (June 30, 2019: $760.6 million). Prior to disruption in the financial markets caused by the COVID-19 pandemic, we invested $5.0 billion in MBS and GSE CRTs during the six months ended June 30, 2020 (June 30, 2019: $5.6 billion). We used cash of $904.4 million to terminate derivative contracts in the six months ended June 30, 2020 (June 30, 2019: $539.6 million) as we sold our Agency securities and our sensitivity to interest rates decreased.

Our financing activities used net cash of $18.2 billion for the six months ended June 30, 2020 primarily because we repaid our repurchase agreement borrowings with proceeds from asset sales (June 30, 2019: net cash provided by financing

54

activities of $3.6 billion). We repaid net repurchase agreement borrowing of $17.5 billion (June 30, 2019: net proceeds provided $3.5 billion). In addition, we repaid $910.0 million of secured loans from the FHLBI. We also used cash of $102.6 million for the six months ended June 30, 2020 (June 30, 2019: $126.8 million) to pay dividends. Proceeds from issuance of common stock provided $347.1 million for the six months ended June 30, 2020 (June 30, 2019: $266.9 million).

Forward-Looking Statements Regarding Liquidity

As of June 30, 2020, our investment portfolio is primarily composed of credit assets that are financed by FHLBI. Our secured loans are due by December 2020, and we intend to repay FHLBI with proceeds from sales of assets that are currently collateralizing our secured loans. We repaid $435.0 million of our secured loans in July 2020.

We have approximately $554.3 million of unencumbered investments as of June 30, 2020 and unrestricted cash of $270.2 million. We resumed investing in Agency RMBS in July 2020 and financed the purchase of these Agency investments with a moderate amount of repurchase agreement borrowings. We determine the amount of leverage on new investments based upon the type of investment and market conditions at the time of investment.

Based upon our current portfolio, existing borrowing arrangements and anticipated proceeds from sales of assets that are currently collateralizing our secured loans, 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, 2020, we had the following contractual obligations:

	Payments Due by Period
$ in thousands	Total	Less than 1 year	1-3 years	3-5 years	After 5 years
Secured loans	740,000	740,000	—	—	—
Interest expense on secured loans (1)	2,141	2,141	—	—	—
Total (2)	742,141	742,141	—	—	—

(1)Interest expense is calculated based on variable rates in effect at June 30, 2020.

(2)Excluded from total contractual obligations are the amounts due to our Manager under the management agreement, as those obligations do not have fixed and determinable payments.

Off-Balance Sheet Arrangements

As of June 30, 2020, we held investments in two unconsolidated joint ventures that are managed by an affiliate of our Manager. We are committed to invest $6.5 million in these unconsolidated joint ventures 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 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 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 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, 2019.

Inflation

Virtually all of our assets and liabilities are sensitive to interest rates. As a result, interest rates and other factors influence our performance far more than inflation. Changes in interest rates do not necessarily correlate with inflation rates or changes in inflation rates.

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.

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, 2020, 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, 2020.

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 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). (“percentage tests”). The SEC staff has issued a “no-action” letter in which it confirmed that it would not recommend enforcement action if an issuer continues to rely on the exclusion provided by Section 3(c)(5)(C) of the 1940 Act if the issuer does not meet the percentage tests if: (1) the inability to meet those tests is the result of the sale of an underlying asset; (2) proceeds from the sale are invested in government securities, certificates of deposit, or other securities appropriate for the purpose of preserving value pending the investment of the proceeds in assets that meet the percentage tests; and (3) the issuer intends to purchase assets that meet the percentage tests as soon as possible but generally within one year. (Medidentic Mortgage Investors, SEC No-Action Letter (May 23, 1984)). In light of this analysis, we believe that as of June 30, 2020, 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 Item Part II. Item 1A - Risk Factors of this Quarterly Report.

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, and TBAs.

The COVID-19 pandemic caused significant dislocations in financial markets, including the interest rates market. In March 2020, the Federal Open Market Committee lowered the Federal Funds target range to 0 to 0.25%. We did not have any interest rate hedges in place as of June 30, 2020 due to limited interest rate sensitivity and prevailing market conditions.

We resumed purchasing 30 year fixed-rate Agency RMBS in July 2020 and financed these purchases with repurchase agreement borrowings. We entered into interest rate swaps to mitigate our interest rate risk associated with these borrowings.

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, during this portion of the interest rate and credit cycles, 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.

57

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 in order to maintain liquidity and preserve book value.

Uncertainties related to the COVID-19 pandemic caused credit spreads to widen significantly in the second half of March 2020 and continuing into April 2020. Unprecedented government responses, including fiscal stimulus, monetary policy actions, and various purchase and financing programs have had 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 pursuant to 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, 2020, assuming a static portfolio and constant financing and credit spreads. When evaluating the impact of changes in interest rates, prepayment assumptions and

58

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.

Change in Interest Rates	Percentage Change in Projected Net Interest Income		Percentage Change in Projected Portfolio Value
+1.00%	(1.93)	%	(2.88)	%
+0.50%	(1.00)	%	(1.47)	%
-0.50%	1.54	%	0.90	%
-1.00%	1.12	%	1.12	%

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, 2020. 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, 2020, 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); 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 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, in light 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.

59

Foreign Exchange Rate Risk

We have an investment of €12.8 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.

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, 2020. 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, 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

60

PART II – OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS.

From time to time, we may be involved in various claims and legal actions arising in the ordinary course of business. As of June 30, 2020, we were not involved in any such legal proceedings.

ITEM 1A.  RISK FACTORS.

There were no material changes during the period covered by this Report to the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019, other than those risks related to the COVID-19 pandemic as described below. Additional risks not presently known, or that we currently deem immaterial, also may have a material adverse effect on our business, financial condition and results of operations.

The COVID-19 pandemic has adversely affected, and will likely continue to adversely affect, the U.S. economy, the mortgage REIT industry and our business.

The COVID-19 pandemic and the related preventative measures are causing significant disruptions to the U.S. and global economies and has contributed to volatility and negative pressure in financial markets. Many businesses, particularly smaller ones within the service-sector, have been forced to close, furlough and/or lay off employees. As a result, U.S. unemployment claims have dramatically risen at unprecedented rates. Other economic activity, including retail sales and industrial production, have slowed as well. Current forecasts of economic activity suggest a meaningful economic contraction in the first half of 2020, with the potential for some economic recovery later in the year. However, the pace, timing and strength of any recovery are still unknown and difficult to predict.

Beginning in the first quarter of 2020, particularly in March, the COVID-19 pandemic began to adversely affect the mortgage REIT industry generally. In addition to negative general economic conditions, the impact of COVID-19 caused severe volatility across asset classes, including mortgage-related assets. Forced sales of the securities and other assets that secure repurchase and other financing arrangements due to drops in fair market value of such collateral have been, and may continue to be, on terms less favorable than might otherwise be available in a regularly functioning market and have, and may continue to generate higher than historical levels of margin calls.

The conditions related to the COVID-19 pandemic discussed above have also adversely affected our business and we expect these conditions to continue during 2020. The significant decrease in economic activity and/or resulting decline in the real estate market could have an adverse effect on the value of our investments in mortgage real estate-related assets. Further, in light 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. Elevated levels of delinquency or default would have an adverse impact on the value of our mortgage related assets. In addition to residential mortgage-related assets, the adverse economic conditions could negatively impact tenants on our commercial property assets resulting in potential delinquencies, defaults or declines in asset values. To the extent current conditions persist or worsen, we expect there to be a negative effect on our results of operations, which may reduce earnings and, in turn, cash available for distribution to our stockholders. The continued spread of COVID-19 could also negatively impact the availability of our Manager’s key personnel necessary to conduct our business.

In response to the COVID-19 pandemic, the U.S. government has taken various actions to support the economy and the continued functioning of the financial markets. The Federal Reserve has announced its commitment to purchase unlimited amounts of U.S. Treasuries, mortgage-backed securities, municipal bonds and other assets. In addition, President Trump signed into law the Coronavirus Aid, Relief, and Economic Security (CARES) Act, which will provide billions of dollars of relief to individuals, businesses, state and local governments, and the health care system suffering the impact of the pandemic, including mortgage loan forbearance and modification programs to qualifying borrowers who have difficulty making their loan payments. There can be no assurance as to how, in the long term, these and other actions by the U.S. government will affect the efficiency, liquidity and stability of the financial and mortgage markets. To the extent the financial or mortgage markets do not respond favorably to any of these actions, or such actions do not function as intended, our business, results of operations and financial condition may continue to be materially adversely affected.

61

Our inability to access funding or the terms on which funding is available could have a material adverse effect on our results of operations and financial condition, particularly in light of ongoing market dislocations resulting from the COVID-19 pandemic.

Our ability to fund our operations, meet financial obligations and finance asset acquisitions may be impacted by an inability to secure and maintain our repurchase agreements with counterparties. Because repurchase agreements are short-term commitments of capital, repurchase agreement counterparties may respond to market conditions in a manner that makes it more difficult for us to renew or replace on a continuous basis maturing short-term financings and have and may continue to impose less favorable conditions when rolling such financings. If we are not able to renew or roll our repurchase agreements or arrange for new financing on terms acceptable to us, or if we default on our financial covenants, are otherwise unable to access funds under our financing arrangements, or if we are required to post more collateral or face larger haircuts on our financings, we may have to dispose of assets at significantly lower prices and at inopportune times, which could cause significant losses, and may also force us to limit our asset acquisition activities.

Issues related to financing are heightened in times of significant volatility in the financial markets, such as those being experienced now in connection with the COVID-19 pandemic. It is possible that our financing counterparties will become unwilling or unable to provide us with financing, and we could be forced to sell our assets at an inopportune time when prices are depressed or markets are illiquid, which could cause significant losses. In addition, if the regulatory capital requirements imposed on our financing counterparties change, they may be required to significantly increase the cost of the financing that they provide to us, or to increase the amounts of collateral they require as a condition to providing us with financing. Our financing counterparties also have revised, and may continue to revise, their eligibility requirements for the types of assets that they are willing to finance or the terms of such financings, including increased haircuts and requiring additional cash collateral, based on, among other factors, the regulatory environment and their management of actual and perceived risk. Moreover, the amount of financing that we receive under our repurchase agreements will be directly related to our counterparties’ valuation of our assets that collateralize the outstanding repurchase agreement financing. Typically, repurchase agreements grant the repurchase agreement counterparty the absolute right to reevaluate the fair market value of the assets that cover the amount financed under the repurchase agreement at any time. If a repurchase agreement counterparty determines in its sole discretion that the value of the assets subject to the repurchase agreement financing has decreased, it has the right to initiate a margin call. These valuations may be different than the values that we ascribe to these assets and may be influenced by recent asset sales at distressed levels by forced sellers. A margin call requires us to transfer additional assets to a repurchase agreement counterparty without any advance of funds from the counterparty for such transfer or to repay a portion of the outstanding repurchase agreement financing. We would also be required to post additional collateral if haircuts increase under a repurchase agreement. In these situations, we could be forced to sell assets at significantly depressed prices to meet such margin calls or increased haircuts and to maintain adequate liquidity, which could cause significant losses.

As a result of the ongoing COVID-19 pandemic, during the six months ended June 30, 2020, we observed a mark-down of a portion of our mortgage assets by the counterparties to our financing arrangements, resulting in us having to post cash or securities to satisfy higher than historical levels of margin calls. Significant margin calls had and could have in the future a material adverse effect on our results of operations, financial condition, business, liquidity and ability to make distributions to our stockholders, and caused and could cause in the future the value of our common stock to decline. We may be and have been forced to sell assets at significantly depressed prices to meet such margin calls and to maintain adequate liquidity. If these trends continue, it will continue to have a negative adverse impact on our liquidity.

Our ability to make distributions to our stockholders has been and may continue to be adversely affected by the COVID-19 pandemic.

The declaration, amount and payment of any future dividends on shares of common stock will be at the sole discretion of our board of directors. Consistent with our intention to enhance our liquidity and strengthen our cash position to take advantage of future opportunities, in the second quarter of 2020, our board of directors reduced our quarterly cash dividend on our shares of common stock from prior quarters. The payment of dividends may be more uncertain during severe market disruption in the mortgage, real estate or related sectors, such as those being experienced now as a result of the COVID-19 pandemic.

Additionally, the Internal Revenue Service issued a revenue procedure permitting “publicly offered” REITs, such as us to pay dividends in a mixture of stock and cash, with at least 10% of the total distribution being paid in cash, to satisfy their REIT distribution requirements. Pursuant to this revenue procedure, we have elected and may elect again in the future to make distributions of our taxable income to common stockholders in a mixture of our common stock and cash. As a result, common stockholders may be required to pay income taxes with respect to such dividends in excess of cash received. If a U.S. stockholder sells the common stock that it receives as a dividend in order to pay this tax, the sale proceeds may be less than the

62

amount included in income with respect to the dividend, depending on the market price of our common stock at the time of the sale. Furthermore, with respect to certain non-U.S. stockholders, we or the applicable withholding agent may be required to withhold U.S. tax with respect to such dividends, including in respect of all or a portion of such dividend that is payable in common stock. In addition, if a significant number of our stockholders determine to sell shares of our common stock in order to pay taxes owed on dividends, it may put downward pressure on the trading price of our common stock.

We have experienced, and may continue to experience, significant changes in our portfolio during times of severe market disruption in the mortgage, real estate or related sectors, such as those being experienced now as a result of the COVID-19 pandemic.

Consistent with current market conditions related to the COVID-19 pandemic and our intention to enhance our liquidity and strengthen our cash position, during the six months ended June 30, 2020, we have reduced leverage and taken other steps to manage our portfolio through unprecedented market volatility and preserve long-term stockholder value, including completing various transactions to reposition our portfolio. Stockholders may not agree with, nor are required to consent to, significant changes to our portfolio.

The COVID-19 pandemic has created an uncertain and volatile interest rate environment, which could adversely affect our business.

The COVID-19 pandemic has created an uncertain and volatile interest rate environment and general fixed income patterns have deviated widely from historical trends, which have and may continue to adversely affect our business. We have experienced historically larger spreads to benchmark rates in the repurchase markets and, in some cases, availability of repurchase financing has been limited or not available. Further, in response to the COVID-19 pandemic, significant government programs, stimulus plans as well as government purchase and finance programs have had and will continue to have an impact on interest rates and fair values of fixed income assets. It is unclear what the impact of these actions will be and how long they will continue to drive the interest rate environment. With respect to prepayments, given the combination of low interest rates, government stimulus and high unemployment, and other disruptions related to the COVID-19 pandemic, it has become more difficult to predict prepayment levels for the securities in our portfolio. Actual prepayment results may be materially different than the assumptions we use. With respect to our hedging activities, we terminated all of our remaining interest rate swaps in March 2020 as we repositioned our portfolio in response to unprecedented market conditions associated with the COVID-19 pandemic and reduced our exposure to interest rate risk. However, we returned to utilizing hedges in July 2020.

Market disruptions caused by the COVID-19 pandemic have made it more difficult for us to determine the fair value of our investments.

As discussed in Note 10 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2019, market-based inputs are generally the preferred source of values for purposes of measuring the fair value of many of our assets under U.S. GAAP. The markets for our investments have experienced, and continue to experience, extreme volatility, reduced transaction volume and liquidity, and disruption as a result of the ongoing COVID-19 pandemic, which has made it more difficult for us, and for the providers of third-party valuations that we use, to rely on market-based inputs in connection with the valuation of many of our assets under U.S. GAAP. In the absence of market inputs, U.S. GAAP permits the use of management assumptions to measure fair value. However, the considerable market volatility and disruption caused by the COVID-19 pandemic and the considerable uncertainty regarding the ultimate impact and duration of the pandemic have made it more difficult for our management to formulate assumptions to measure the fair value of certain of our assets.

The fair value of certain of our investments may fluctuate over short periods of time, and our determinations of fair value may differ materially from the values that would have been used if a ready market for these investments existed. The value of our common stock and preferred stock could be adversely affected if our determinations regarding the fair value of these investments were materially higher than the values that we ultimately realize upon their disposal.

We have experienced, and may experience in the future, a decline in the fair value of our investments as a result of the COVID-19 pandemic, which could materially and adversely affect us.

During the six months ended June 30, 2020, we experienced a significant amount of realized and unrealized losses on our assets. A future decline in the fair value of our investments as a result of the COVID-19 pandemic may require us to recognize an impairment under U.S. GAAP if we were to determine that, with respect to any assets in unrealized loss positions, we do not

63

have the ability and intent to hold such assets to maturity or for a period of time sufficient to allow for recovery to the original acquisition cost of such assets. If such a determination were to be made, we would recognize unrealized losses through earnings and write down the amortized cost of such assets to a new cost basis, based on the fair value of such assets on the date they are considered to be impaired. Such impairment charges reflect non-cash losses at the time of recognition. The subsequent disposition or sale of such assets could further affect our future losses or gains, as they are based on the difference between the sale price received and adjusted amortized cost of such assets at the time of sale. If we experience a decline in the fair value of our investments, it could materially and adversely affect our business, results of operations, financial condition and ability to make distributions to our stockholders.

Measures intended to prevent the spread of COVID-19 could disrupt our operations.

In response to the outbreak of COVID-19 and the federal and state mandates implemented to control its spread, a significant portion of our Manager’s employees are working remotely. If our Manager’s employees are unable to work effectively as a result of the COVID-19 pandemic, including because of illness, quarantines, office closures, ineffective remote work arrangements or technology failures or limitations, our operations would be adversely impacted. Further, remote work arrangements may increase the risk of cyber-security incidents and cyber-attacks, which could have a material adverse effect on our business and results of operations, due to, among other things, the loss of investor or proprietary data, interruptions or delays in the operation of our business and damage to our reputation.

We may incur losses as a result of unforeseen or catastrophic events, including the emergence of a pandemic, terrorist attacks, extreme weather events or other natural disasters.

The occurrence of unforeseen or catastrophic events, including the emergence of a pandemic, such as COVID-19, or other widespread health emergency (or concerns over the possibility of such an emergency), terrorist attacks or natural disasters, could create economic and financial disruptions, and could lead to material adverse declines in the market values of our assets, illiquidity in our investment and financing markets and negatively impact our ability to effectively conduct our business.

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 residential and commercial mortgage-backed securities ("MBS") and other mortgage-related assets. 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 conduct our business through IAS Operating Partnership LP (the "Operating Partnership") and have one operating segment.

We have historically invested 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 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");

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

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

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

•Residential and commercial mortgage loans; and

•Other real estate-related financing agreements.

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.

During the six months ended June 30, 2020, we experienced unprecedented market conditions as a result of the COVID-19 pandemic that resulted in a material adverse change in our financial condition. In the three and six months ended June 30, 2020, we recorded a net loss of $299.9 million and $1.9 billion, respectively. Our stockholders' equity declined from $2.9 billion as of December 31, 2019 to $1.2 billion as of June 30, 2020.

Due to significant spread widening in both Agency and non-Agency securities, we received an unusually high number of margin calls from counterparties in the latter half of March 2020. As a result, we were unable to meet margin calls and were not in compliance with the terms of our various borrowings arrangements as of March 31, 2020 as described in Note 6 - "Borrowings". To generate liquidity and reduce leverage, we sold MBS and GSE CRTs for cash proceeds of $23.1 billion and repaid $17.5 billion of our repurchase agreements and $910.0 million of Federal Home Loan Bank of Indianapolis "FHLBI" secured loans during the six months ended June 30, 2020. Our investment portfolio decreased from $21.9 billion as of December 31, 2019 to $1.6 billion as of June 30, 2020 primarily due to these asset sales. We also terminated our entire interest rate swap portfolio as our exposure to interest rate risk decreased as we sold Agency assets.

While the Federal Reserve has taken a number of proactive measures to bolster liquidity, we expect market conditions for the mortgage REIT industry to continue to be challenging due to the uncertainty around the duration and ultimate impact of the COVID-19 pandemic.

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, 2019.

Our condensed consolidated financial statements have been prepared in accordance with 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 the 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 recognition 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, 2019 other than as discussed below.

Mortgage-Backed and Credit Risk Transfer Securities

Allowances for Credit Losses on Available-For-Sale Securities

We are not required to measure expected credit losses for situations in which historic credit loss information, adjusted for current conditions and reasonable and supportable forecasts, results in an expectation that nonpayment of the amortized cost basis is zero. We consider our Agency portfolio to have zero loss expectation because (i) there have been no historical credit losses, (ii) full and timely payment of principal and interest is guaranteed by the GSEs and (iii) the yields, while not risk free, generally trade based on prepayment and liquidity risk as opposed to credit risk. Our available-for-sale GSE CRTs are hybrid financial instruments consisting of a debt host contract and an embedded credit derivative. The embedded credit derivative is carried at fair value with changes in fair value reported in earnings.

For non-Agency RMBS and non-Agency CMBS, we use a discounted cash flow method to estimate and recognize an allowance for credit losses. We calculate the allowance for credit losses as the difference between prepayment adjusted contractual cash flows without credit losses and expected cash flows discounted at the effective interest rate used to recognize interest income on the investment. In developing an expectation of credit losses, we use internal models that analyze the loans underlying each investment and evaluate factors including, but not limited to, delinquency status, loan-to-value ratios, borrower credit scores, occupancy status and geographic concentration. We place reliance on these internal models in determining credit quality.

We record an allowance for credit losses as a contra-asset on the condensed consolidated balance sheets and a provision for credit losses in the condensed consolidated statements of operations. Credit losses are accreted into earnings over time at the effective interest rate used to recognize interest income. Subsequent favorable or adverse changes in the amount of expected credit losses are recognized immediately in earnings. If the allowance for credit losses has been reduced to zero, we reflect the remaining favorable changes as a prospective adjustment to the effective interest rate of the investment. The allowance for credit losses is limited to the amount by which the investment’s amortized cost exceeds fair value. When the allowance for credit losses is limited, the effective interest rate used to recognize interest income and accrete credit losses is prospectively adjusted. We do not record an allowance for credit losses when an investment’s fair value exceeds its amortized cost. Recoveries of amounts previously written off relating to improvements in cash flows are recognized in earnings when received. We record provisions for credit losses, reductions in provisions for credit losses, accretion of credit losses, and recoveries of amounts previously written off within gain (loss) on investments, net in our condensed consolidated statements of operations.

When we determine that we intend to sell, or more likely than not will be required to sell, an available-for-sale security in an unrealized loss position before we recover its amortized cost, we write off any allowance for credit losses and write down the investment’s amortized cost to its fair value. We record the write off of the allowance for credit losses and write down of the available-for-sale security within gain (loss) on investments, net in our condensed consolidated statements of operations.

We present accrued interest receivable separately from our investment portfolio on our condensed consolidated balance sheets. We do not estimate an allowance for credit losses on accrued interest receivable because we write off accrued interest receivable as a reduction to interest income if it is not received when due.

Interest Income Recognition

Mortgage-Backed Securities

Interest income on MBS is accrued based on the outstanding principal or notional balance of the securities and their contractual terms. Premiums or discounts are amortized or accreted into interest income over the life of the investment using the effective interest method.

Interest income on our MBS where we may not recover substantially all of our initial investment is based on estimated future cash flows. We estimate future expected cash flows at the time of purchase and determine the effective interest rate based

on these estimated cash flows and our purchase price. Over the life of the investments, we update these estimated future cash flows and compute a revised yield based on the current amortized cost of the investment. In situations where an allowance for credit losses is limited by the fair value of the investment, we compute the yield as the rate that equates expected future cash flows to the current fair value of the investment. In estimating these future cash flows, there are a number of assumptions that are subject to uncertainties and contingencies, including but not limited to the rate and timing of principal payments (prepayments, repurchases, defaults and liquidations), the pass through or coupon rate, and interest rate fluctuations. These uncertainties and contingencies are difficult to predict and are subject to future events that may impact our estimate and our interest income. Changes in our original or most recent cash flow projections may result in a prospective change in interest income recognized on these securities, or the amortized cost of these securities. For non-Agency RMBS not of high credit quality, when actual cash flows vary from expected cash flows, the difference is recorded as an adjustment to the amortized cost of the security, unless those changes relate to credit losses that will be reflected in an allowance for credit losses, and the security's yield is revised prospectively.

For Agency RMBS and Agency CMBS that cannot be prepaid in such a way that we would not recover substantially all of our initial investment, interest income recognition is based on contractual cash flows. We do not estimate prepayments in applying the effective interest method.

Fair Value Measurements

As of January 1, 2020, we report our commercial loan at fair value as determined by an independent pricing service. The pricing service values the loan using a discounted cash flow analysis. The yield used in the discounted cash flow analysis is determined by comparing the features of the loan to the interest rates and terms required by lenders in the new loan origination market for similar loans and the yield required by investors acquiring mezzanine loans in the secondary market and a comparison of current market and collateral conditions to those present at origination. We discontinued reporting our commercial loan at amortized cost because we elected the fair value option for this loan in connection with our adoption of the new guidance for reporting credit losses discussed below.

Accounting Pronouncements Recently Adopted

On January 1, 2020, we adopted the accounting guidance that changes how entities report credit losses for assets measured at amortized cost and available-for-sale securities. The new guidance significantly changes how entities measure credit losses for most financial assets, including loans, that are not measured at fair value through net income. The guidance replaces the existing “incurred loss” model with an “expected loss” model for instruments measured at amortized cost and requires entities to record credit allowances for available-for-sale debt securities rather than reduce the carrying amount, as they previously did under the other-than-temporary impairment model. The new guidance also simplifies the accounting model for purchased credit-impaired debt securities and loans and requires that entities record an adjustment to retained earnings on January 1, 2020 for the cumulative effect of adopting the new guidance. We were not required to record a cumulative effect adjustment to retained earnings because all of our purchased credit-impaired securities were in an unrealized gain position as of the implementation date.

The new guidance specifically excludes available-for-sale securities measured at fair value through net income. We elected the fair value option for all MBS purchased on or after September 1, 2016 and GSE CRTs purchased on or after August 24, 2015. Accordingly, the impact of the new guidance on accounting for our debt securities is limited to those securities purchased prior to election of the fair value option and held on January 1, 2020. For further information on the composition of our investment portfolio, see Note 4 - "Mortgage Backed and Credit Risk Transfer Securities". During the three and six months ended June 30, 2020, we recorded $6.3 million and $85.1 million, respectively, of impairment on non-Agency securities that we intend to sell or more likely than not will be required to sell before we recover the amortized cost basis of the security. We recorded the impairment within gain (loss) on investments, net in our condensed consolidated statements of operations. As of June 30, 2020, we have not recorded a credit loss allowance on any of our securities.

We had one commercial loan as of December 31, 2019 that was measured at amortized cost. We implemented the new guidance for this loan by electing the fair value option and recording a cumulative effect adjustment to increase retained earnings by $342,000 on January 1, 2020. We recognized $785,000 and $2.5 million of unrealized losses on our commercial loan in our condensed consolidated statement of operations during the three and six months ended June 30, 2020, respectively.

Accounting Pronouncements Recently Issued

In March 2020, new accounting guidance was issued for evaluating the effects of reference rate reform on financial reporting. The new guidance provides 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" or another reference rate that is expected to be discontinued due to reference rate reform. The guidance may be adopted on or after March 12, 2020 and is only effective for the period from March 12, 2020 through December 31, 2022. We have not yet adopted this guidance and 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

As discussed in Note 1 - "Organization and Business Operations", we sold MBS and GSE CRTs for cash proceeds of $23.1 billion during the six months ended June 30, 2020 to generate liquidity and reduce leverage given unprecedented market conditions as a result of the COVID-19 pandemic.

The following tables summarize our MBS and GSE CRT portfolio by asset type as of June 30, 2020 and December 31, 2019.

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, 2020 and December 31, 2019. We have elected the fair value option for all of our RMBS interest-only securities, our MBS purchased on or after September 1, 2016 and our GSE CRTs purchased on or after August 24, 2015. As of June 30, 2020 and December 31, 2019, approximately 15% and 80%, respectively, of our MBS and GSE CRTs are accounted for under the fair value option. Our percentage of MBS and GSE CRTs accounted for under the fair value option declined as of June 30, 2020 due to sales of securities accounted for under the fair value option during the six months ended June 30, 2020.

(2)Unrealized losses on available-for-sale non-Agency CMBS are primarily due to the COVID-19 pandemic and its impact on market liquidity and underlying commercial real estate fundamentals. We have not recorded an allowance for credit losses on these securities as of June 30, 2020 based on a comparison of discounted expected cash flows to current amortized cost basis.

(3)Unrealized losses, other than those on available-for-sale non-Agency CMBS, relate to securities or embedded derivatives that are recorded at fair value through earnings.

(6)Fair value option has been elected for all GSE CRT that are in an unrealized loss position.

On January 1, 2020, we adopted accounting guidance that requires us to estimate an allowance for credit losses on available-for-sale securities in unrealized loss positions. As of June 30, 2020, we have not recorded an allowance for credit losses on any of our securities. We did not record any provisions for credit losses on our condensed consolidated statement of operations during the three and six months ended June 30, 2020. We recorded impairments of $6.3 million and $85.1 million on our condensed consolidated statement of operations 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.

Prior to January 1, 2020, we assessed our investment securities for other-than-temporary impairment ("OTTI") on a quarterly basis. When the fair value of an investment was less than its amortized cost at the balance sheet date of the reporting

period for which impairment was assessed, the impairment was designated as either "temporary" or "other-than-temporary." This analysis included a determination of estimated future cash flows through an evaluation of the characteristics of the underlying loans and the structural features of the investment. Underlying loan characteristics reviewed included, but were not limited to, delinquency status, loan-to-value ratios, borrower credit scores, occupancy status and geographic concentration.

The following table summarizes OTTI included in earnings during the three and six months ended June 30, 2019:

	Three months ended June 30,		Six Months Ended June 30,
$ in thousands		2019		2019
RMBS interest-only securities		489		1,952
Non-Agency RMBS (1)		711		1,024
Total		1,200		2,976

(1)Amounts disclosed relate to credit losses on debt securities for which a portion of an other-than-temporary impairment was recognized in other comprehensive income.

OTTI on RMBS interest-only securities was recorded as a reclassification from an unrealized to realized loss within gain (loss) on investments, net on the condensed consolidated statements of operations because we account for these securities under the fair value option.

The following table summarizes the components of our total gain (loss) on investments, net for the three and six months ended June 30, 2020 and 2019.

IAS Services LLC, our wholly-owned subsidiary, is required to purchase and hold Federal Home Loan Bank of Indianapolis ("FHLBI") stock as a condition of membership in the FHLBI. The stock is recorded at cost.

We had a participation interest in a secured loan collateralized by mortgage servicing rights that bears interest at a floating rate based on LIBOR plus a spread. We sold our participation interest for $21.6 million on April 1, 2020. The weighted average asset yield for the participation interest was 5.82% as of December 31, 2019. We recorded a realized loss of $3.8 million upon sale of the participation interest.

We have an investment in a commercial loan that matures in February 2021. The loan had a weighted average coupon rate of 8.67% as of June 30, 2020 and 10.19% as of December 31, 2019. As discussed in Note 2- "Summary of Significant Accounting Policies", we elected the fair value option for this loan on January 1, 2020 and recorded a cumulative effect adjustment to increase retained earnings by $342,000 on January 1, 2020. We recorded an unrealized loss on this loan of $785,000 and $2.5 million during the three and six months ended June 30, 2020, respectively, based on a discounted cash flow valuation prepared by an independent pricing service. We previously reported this loan at amortized cost on our condensed consolidated balance sheet.

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.

Secured Loans

As of June 30, 2020, IAS Services LLC had $740.0 million in outstanding secured loans from the FHLBI. These secured loans have variable rates that are based on the FHLBI's short-term cost of funds. For the six months ended June 30, 2020, IAS Services LLC had weighted average borrowings of $1.13 billion with a weighted average borrowing rate of 1.48%, and a weighted average maturity of 0.4 years.

In April 2020, the FHLBI modified the terms of our secured loans because we were not in compliance with all of the financial covenants of our secured loan agreements as of March 31, 2020. The modified loan terms require repayment of our secured loans by December 2020 but allow for prepayment at any time without penalty. We intend to repay our secured loans by December 2020 with proceeds from sales of mortgage-backed securities that are collateralizing our secured loans. We determined that the modification of our loan terms was a troubled debt restructuring that did not impact the accounting for our secured loans.

As discussed in Note 5 - "Other Assets," IAS Services LLC is required to purchase and hold a certain amount of FHLBI stock, which is based, in part, upon the outstanding principal balance of secured loans from the FHLBI.

Repurchase Agreements

As discussed in Note 1 - “Organization and Business Operations”, 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 and were not in compliance with all of the financial covenants of our repurchase agreements as of March 31, 2020. Certain of our repurchase agreement counterparties entered into forbearance discussions with us and permitted our repurchase agreements to remain outstanding while we were not in compliance.

In addition, certain of our counterparties seized and sold securities that we had posted as collateral for our repurchase agreements. Gains and losses associated with the termination of these repurchase agreements are reported as a net gain (loss) on extinguishment of debt in our condensed consolidated statement of operations.

We repaid all of our repurchase agreements as of May 7, 2020 and did not have any repurchase agreement borrowings as of June 30, 2020.

Collateral Positions

Collateral Positions

The following table summarizes the fair value of collateral that we pledged and held under our repurchase agreements, secured loans, interest rate swaps and currency forward contracts as of June 30, 2020 and December 31, 2019. 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, 2019 for a description of how we determine fair value. RMBS, CMBS and GSE CRT collateral pledged is included in mortgage-backed and credit risk transfer securities on our condensed consolidated balance sheets. Loan participation interest collateral pledged was included in other assets on our condensed consolidated balance sheets. Cash collateral pledged on secured loans, 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 was classified as due from counterparties on our condensed consolidated balance sheets.

Agency CMBS purchase commitments that are recorded as mortgage-backed and credit risk transfer securities on our condensed consolidated balance sheets cannot be pledged as collateral until these securities settle. We held approximately $96.2 million of these securities as of December 31, 2019. We did not have any Agency CMBS purchase commitments as of June 30, 2020.

Cash collateral held on repurchase agreements 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, 2020 and December 31, 2019, 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 or fund margin calls if the value of pledged assets declined.

Our repurchase agreement collateral pledged ratio (MBS, GSE CRTs and a loan participation interest pledged as collateral/amount outstanding) was 109% as of December 31, 2019. We did not have any repurchase agreements as of June 30, 2020.

Secured Loans

Collateral pledged with the FHLBI is held in trust for the benefit of the FHLBI and is not commingled with our other assets. The FHLBI does not have the right to resell or repledge collateral posted unless an event of default occurs. The FHLBI retains the right to mark the underlying collateral for FHLBI advances to fair value as determined by the FHLBI in its sole discretion. IAS Services LLC would be required to provide additional collateral to meet margin calls if the value of pledged assets declines. See Note 6 - "Borrowings" for a discussion of the status of our FHLBI secured loans.

Interest Rate Swaps

All of the interest rate swaps that we have entered into during 2020 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 consolidated statements of operations. Our FCM agreements include cross default provisions. We were not a party to any interest rate swaps as of June 30, 2020.

Currency Forward Contracts

Our currency forward contract provides for bilateral collateral pledging based on market value as determined by our counterparty. Collateral pledged with our currency forward counterparty is segregated in our books and records and can be in the form of cash or securities. Our counterparty has the right to repledge the collateral posted, but has the obligation to return the pledged collateral, or substantially the same collateral, if agreed to by us, as the market value of the currency forward contract 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. In addition, our secured loans have floating interest rates. As such, we are exposed to changing interest rates. 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. Interest rate swaps involve making fixed-rate payments to a counterparty in exchange for the receipt of variable-rate amounts over the life of the agreements without exchange of the underlying notional amount.

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 $4.5 million and $14.6 million as a decrease (June 30, 2019: $5.9 million and $11.8 million as a decrease) to interest expense for the three and six months ended June 30, 2020, 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 is probable that the original forecasted repurchase agreement transactions will not occur by the end of the originally specified time period. During the next 12 months, we estimate that $20.0 million will be reclassified as a decrease to interest expense, repurchase agreements. As of June 30, 2020, $61.3 million (December 31, 2019: $75.9 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.

We did not have any interest rate swaps outstanding as of June 30, 2020. As of December 31, 2019, we had interest rate swaps with the following maturities outstanding:

$ in thousands	As of December 31, 2019

Futures and Currency Forward Contracts

We purchase or sell U.S. Treasury futures contracts to help mitigate the potential impact of changes in interest rates on the performance of our investment portfolio. We recognize realized and unrealized gains and losses associated with the purchases or sales U.S. Treasury futures contracts in gain (loss) on derivative instruments, net in our condensed consolidated statements of operations. We did not have any futures contract outstanding as of June 30, 2020 and December 31, 2019.

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, 2020, we had $22.9 million (December 31, 2019: $23.1 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 are accounted for as hybrid financial instruments consisting of a debt host contract and an embedded credit derivative. Embedded derivatives associated with GSE CRTs are recorded within mortgage-backed and credit risk transfer securities, at fair value, on the condensed consolidated balance sheets. At June 30, 2020 and December 31, 2019, terms of the GSE CRT embedded derivatives are:

Offsetting [Abstract]

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, 2020 and December 31, 2019. The daily variation margin payment for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral. Our derivative asset of $18.5 million as of December 31, 2019 related to centrally cleared interest rate swaps is not included in the table below as a result of this characterization of daily variation margin.

(2)The fair value of securities pledged as initial margin against our centrally cleared swaps was $189.8 million as of December 31, 2019. Cash collateral pledged on our currency forward contracts and centrally cleared interest rate swaps was $480,000 and $116.4 million as of June 30, 2020 and December 31, 2019, respectively. 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 $160,000 at December 31, 2019.

(3)The fair value of securities pledged against IAS Services LLC's borrowings under secured loans was $1.1 billion and $1.9 billion at June 30, 2020 and December 31, 2019, respectively. We pledged cash collateral against secured loans of $929,000 and $600,000 as of June 30, 2020 and December 31, 2019, respectively.

(4)The fair value of securities pledged against our borrowing under repurchase agreements was $19.1 billion at December 31, 2019. We pledged cash collateral of $32.6 million and held cash collateral of $10,000 under repurchase agreements as of December 31, 2019.

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.

(1)For more detail about the fair value of our MBS and GSE CRTs, refer to Note 4 - "Mortgage-Backed and Credit Risk Transfer Securities."

(2)Our GSE CRTs purchased prior to August 24, 2015 are accounted for as hybrid financial instruments with an embedded derivative. The hybrid financial instruments consist of debt host contracts classified as Level 2 and embedded derivatives classified as Level 3. As of June 30, 2020, the net embedded derivative liability position of $17.2 million includes $100,000 of embedded derivatives in an asset position and $17.3 million of embedded derivatives in a liability position. As of December 31, 2019, the net embedded derivative asset position of $10.3 million includes $19.5 million of embedded derivatives in an asset position and $9.2 million of embedded derivatives in a liability position.

(3)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, 2020 and December 31, 2019, the weighted average remaining term of our investments in unconsolidated ventures was 1.9 years and 2.2 years, respectively.

(4)Includes $44.7 million of a loan participation interest as of December 31, 2019 and $21.8 million of a commercial loan as of June 30, 2020. We elected the fair value option for our commercial loan as of January 1, 2020 and valued the loan based on a third party appraisal as of June 30, 2020. We sold the loan participation interest on April 1, 2020.

These significant unobservable inputs change according to market conditions and security performance. We estimate the weighted average life of GSE CRTs in order to identify GSE corporate debt with a similar maturity. We obtain our weighted average life estimates from a third party provider. Although weighted average life is a significant input, changes in weighted average life may not have an explicit directional impact on the fair value measurement.

(1)We elected the fair value option for our commercial loan on January 1, 2020.

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 our commercial loan, held-for-investment, included in "Other assets" on our condensed consolidated balance sheet as of December 31, 2019, is a Level 3 fair value measurement. The fair value was determined by an independent pricing service using a discounted cash flow analysis.

•The estimated fair value of FHLBI stock, included in "Other assets" on our condensed consolidated balance sheets, is a Level 3 fair value measurement. FHLBI stock may only be sold back to the FHLBI at its discretion at par. As a result, the cost of the FHLBI stock approximates its fair value.

•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.

•The estimated fair value of secured loans is a Level 3 fair value measurement. As of June 30, 2020, the secured loans have variable rates based on the FHLBI's short-term cost of funds. As of December 31, 2020, the secured loans had floating rates based on an index plus a spread and the spread was typically consistent with those demanded in the

market. Accordingly, the interest rates on these secured loans are at market, and thus the carrying amount approximates fair value.

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, 2019.

Consolidation

Our condensed consolidated financial statements have been prepared in accordance with 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 the 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 recognition on mortgage-backed and credit risk transfer securities and allowances for credit losses. Actual results may differ from those estimates.

Mortgage-Backed and Credit Risk Transfer Securities

Mortgage-Backed and Credit Risk Transfer Securities

Allowances for Credit Losses on Available-For-Sale Securities

We are not required to measure expected credit losses for situations in which historic credit loss information, adjusted for current conditions and reasonable and supportable forecasts, results in an expectation that nonpayment of the amortized cost basis is zero. We consider our Agency portfolio to have zero loss expectation because (i) there have been no historical credit losses, (ii) full and timely payment of principal and interest is guaranteed by the GSEs and (iii) the yields, while not risk free, generally trade based on prepayment and liquidity risk as opposed to credit risk. Our available-for-sale GSE CRTs are hybrid financial instruments consisting of a debt host contract and an embedded credit derivative. The embedded credit derivative is carried at fair value with changes in fair value reported in earnings.

For non-Agency RMBS and non-Agency CMBS, we use a discounted cash flow method to estimate and recognize an allowance for credit losses. We calculate the allowance for credit losses as the difference between prepayment adjusted contractual cash flows without credit losses and expected cash flows discounted at the effective interest rate used to recognize interest income on the investment. In developing an expectation of credit losses, we use internal models that analyze the loans underlying each investment and evaluate factors including, but not limited to, delinquency status, loan-to-value ratios, borrower credit scores, occupancy status and geographic concentration. We place reliance on these internal models in determining credit quality.

We record an allowance for credit losses as a contra-asset on the condensed consolidated balance sheets and a provision for credit losses in the condensed consolidated statements of operations. Credit losses are accreted into earnings over time at the effective interest rate used to recognize interest income. Subsequent favorable or adverse changes in the amount of expected credit losses are recognized immediately in earnings. If the allowance for credit losses has been reduced to zero, we reflect the remaining favorable changes as a prospective adjustment to the effective interest rate of the investment. The allowance for credit losses is limited to the amount by which the investment’s amortized cost exceeds fair value. When the allowance for credit losses is limited, the effective interest rate used to recognize interest income and accrete credit losses is prospectively adjusted. We do not record an allowance for credit losses when an investment’s fair value exceeds its amortized cost. Recoveries of amounts previously written off relating to improvements in cash flows are recognized in earnings when received. We record provisions for credit losses, reductions in provisions for credit losses, accretion of credit losses, and recoveries of amounts previously written off within gain (loss) on investments, net in our condensed consolidated statements of operations.

When we determine that we intend to sell, or more likely than not will be required to sell, an available-for-sale security in an unrealized loss position before we recover its amortized cost, we write off any allowance for credit losses and write down the investment’s amortized cost to its fair value. We record the write off of the allowance for credit losses and write down of the available-for-sale security within gain (loss) on investments, net in our condensed consolidated statements of operations.

We present accrued interest receivable separately from our investment portfolio on our condensed consolidated balance sheets. We do not estimate an allowance for credit losses on accrued interest receivable because we write off accrued interest receivable as a reduction to interest income if it is not received when due.

Interest Income Recognition

Interest Income Recognition

Mortgage-Backed Securities

Interest income on MBS is accrued based on the outstanding principal or notional balance of the securities and their contractual terms. Premiums or discounts are amortized or accreted into interest income over the life of the investment using the effective interest method.

Interest income on our MBS where we may not recover substantially all of our initial investment is based on estimated future cash flows. We estimate future expected cash flows at the time of purchase and determine the effective interest rate based

on these estimated cash flows and our purchase price. Over the life of the investments, we update these estimated future cash flows and compute a revised yield based on the current amortized cost of the investment. In situations where an allowance for credit losses is limited by the fair value of the investment, we compute the yield as the rate that equates expected future cash flows to the current fair value of the investment. In estimating these future cash flows, there are a number of assumptions that are subject to uncertainties and contingencies, including but not limited to the rate and timing of principal payments (prepayments, repurchases, defaults and liquidations), the pass through or coupon rate, and interest rate fluctuations. These uncertainties and contingencies are difficult to predict and are subject to future events that may impact our estimate and our interest income. Changes in our original or most recent cash flow projections may result in a prospective change in interest income recognized on these securities, or the amortized cost of these securities. For non-Agency RMBS not of high credit quality, when actual cash flows vary from expected cash flows, the difference is recorded as an adjustment to the amortized cost of the security, unless those changes relate to credit losses that will be reflected in an allowance for credit losses, and the security's yield is revised prospectively.

For Agency RMBS and Agency CMBS that cannot be prepaid in such a way that we would not recover substantially all of our initial investment, interest income recognition is based on contractual cash flows. We do not estimate prepayments in applying the effective interest method.

Fair Value Measurements

Fair Value Measurements

As of January 1, 2020, we report our commercial loan at fair value as determined by an independent pricing service. The pricing service values the loan using a discounted cash flow analysis. The yield used in the discounted cash flow analysis is determined by comparing the features of the loan to the interest rates and terms required by lenders in the new loan origination market for similar loans and the yield required by investors acquiring mezzanine loans in the secondary market and a comparison of current market and collateral conditions to those present at origination. We discontinued reporting our commercial loan at amortized cost because we elected the fair value option for this loan in connection with our adoption of the new guidance for reporting credit losses discussed below.

Accounting Pronouncements Recently Adopted and Accounting Pronouncements Recently Issued

Accounting Pronouncements Recently Adopted

On January 1, 2020, we adopted the accounting guidance that changes how entities report credit losses for assets measured at amortized cost and available-for-sale securities. The new guidance significantly changes how entities measure credit losses for most financial assets, including loans, that are not measured at fair value through net income. The guidance replaces the existing “incurred loss” model with an “expected loss” model for instruments measured at amortized cost and requires entities to record credit allowances for available-for-sale debt securities rather than reduce the carrying amount, as they previously did under the other-than-temporary impairment model. The new guidance also simplifies the accounting model for purchased credit-impaired debt securities and loans and requires that entities record an adjustment to retained earnings on January 1, 2020 for the cumulative effect of adopting the new guidance. We were not required to record a cumulative effect adjustment to retained earnings because all of our purchased credit-impaired securities were in an unrealized gain position as of the implementation date.

The new guidance specifically excludes available-for-sale securities measured at fair value through net income. We elected the fair value option for all MBS purchased on or after September 1, 2016 and GSE CRTs purchased on or after August 24, 2015. Accordingly, the impact of the new guidance on accounting for our debt securities is limited to those securities purchased prior to election of the fair value option and held on January 1, 2020. For further information on the composition of our investment portfolio, see Note 4 - "Mortgage Backed and Credit Risk Transfer Securities". During the three and six months ended June 30, 2020, we recorded $6.3 million and $85.1 million, respectively, of impairment on non-Agency securities that we intend to sell or more likely than not will be required to sell before we recover the amortized cost basis of the security. We recorded the impairment within gain (loss) on investments, net in our condensed consolidated statements of operations. As of June 30, 2020, we have not recorded a credit loss allowance on any of our securities.

We had one commercial loan as of December 31, 2019 that was measured at amortized cost. We implemented the new guidance for this loan by electing the fair value option and recording a cumulative effect adjustment to increase retained earnings by $342,000 on January 1, 2020. We recognized $785,000 and $2.5 million of unrealized losses on our commercial loan in our condensed consolidated statement of operations during the three and six months ended June 30, 2020, respectively.

Accounting Pronouncements Recently Issued

In March 2020, new accounting guidance was issued for evaluating the effects of reference rate reform on financial reporting. The new guidance provides 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" or another reference rate that is expected to be discontinued due to reference rate reform. The guidance may be adopted on or after March 12, 2020 and is only effective for the period from March 12, 2020 through December 31, 2022. We have not yet adopted this guidance and are currently evaluating what impact the guidance will have on our consolidated financial statements.

Schedule of Fair Value of Collateral Hold and Pledged

The following table summarizes the fair value of collateral that we pledged and held under our repurchase agreements, secured loans, interest rate swaps and currency forward contracts as of June 30, 2020 and December 31, 2019. 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, 2019 for a description of how we determine fair value. RMBS, CMBS and GSE CRT collateral pledged is included in mortgage-backed and credit risk transfer securities on our condensed consolidated balance sheets. Loan participation interest collateral pledged was included in other assets on our condensed consolidated balance sheets. Cash collateral pledged on secured loans, 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 was classified as due from counterparties on our condensed consolidated balance sheets.

Agency CMBS purchase commitments that are recorded as mortgage-backed and credit risk transfer securities on our condensed consolidated balance sheets cannot be pledged as collateral until these securities settle. We held approximately $96.2 million of these securities as of December 31, 2019. We did not have any Agency CMBS purchase commitments as of June 30, 2020.

Cash collateral held on repurchase agreements 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, 2020 and December 31, 2019, we did not recognize any non-cash collateral held on our condensed consolidated balance sheets.

Schedule of Offsetting Derivative 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, 2020 and December 31, 2019. The daily variation margin payment for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral. Our derivative asset of $18.5 million as of December 31, 2019 related to centrally cleared interest rate swaps is not included in the table below as a result of this characterization of daily variation margin.
