ARLINGTON ASSET INVESTMENT CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands, except per share data)

(Unaudited)

Note 1. Organization and Basis of Presentation

Arlington Asset Investment Corp. (“Arlington Asset”) and its consolidated subsidiaries (unless the context otherwise provides, collectively, the “Company”) is an investment firm that focuses primarily on investing in mortgage related assets and residential real estate.  The Company’s investment capital is currently allocated between agency mortgage-backed securities (“MBS”), mortgage servicing right (“MSR”) related assets, mortgage credit investments and single-family residential (“SFR”) properties.

The Company’s agency MBS consist of residential mortgage pass-through certificates for which the principal and interest payments are guaranteed by either a U.S. government sponsored enterprise (“GSE”), such as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or by a U.S. government agency, such as the Government National Mortgage Association (“Ginnie Mae”).  The Company’s MSR related assets represent investments for which the return is based on the economic performance of a pool of specific MSRs.  The Company’s mortgage credit investments generally include investments in mortgage loans secured by either residential or commercial real property or MBS collateralized by residential or commercial mortgage loans (“non-agency MBS”).  The principal and interest of the Company’s mortgage credit investments are not guaranteed by a GSE or a U.S government agency.  The Company’s SFR investment strategy is to acquire, lease and operate single-family residential homes as rental properties.

Arlington Asset is a Virginia corporation. The Company is internally managed and does not have an external investment advisor.

The Company has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). As a REIT, the Company is required to distribute annually 90% of its REIT taxable income (subject to certain adjustments). So long as the Company continues to qualify as a REIT, it will generally not be subject to U.S. Federal or state corporate income taxes on its taxable income that it distributes to its shareholders on a timely basis. At present, it is the Company’s intention to distribute 100% of its taxable income, although the Company will not be required to do so. The Company intends to make distributions of its taxable income within the time limits prescribed by the Internal Revenue Code, which may extend into the subsequent taxable year.

The unaudited interim consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X. The Company’s unaudited interim consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

The Company’s consolidated financial statements include the accounts of Arlington Asset and all other entities in which the Company has a controlling financial interest. All intercompany accounts and transactions have been eliminated in consolidation.

The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect amounts reported in the consolidated financial statements. Although the Company bases these estimates and assumptions on historical experience and all other reasonably available information that the Company believes to be relevant under the circumstances, such estimates frequently require management to exercise significant subjective judgment about matters that are inherently uncertain. Actual results may differ from these estimates materially.

Certain amounts in the consolidated financial statements and notes for prior periods have been reclassified to conform to the current year’s presentation. These reclassifications had no impact on the previously reported net income, total assets or total liabilities.

Note 2. Summary of Significant Accounting Policies

Cash Equivalents

Cash equivalents include demand deposits with banks, money market accounts and highly liquid investments with original maturities of three months or less. As of September 30, 2021 and December 31, 2020, approximately 64% and 99%, respectively, of

6

the Company’s cash equivalents were invested in money market funds that invest primarily in U.S. Treasuries and other securities backed by the U.S. government.

Investment Security Purchases and Sales

Purchases and sales of investment securities are recorded on the settlement date of the transfer unless the trade qualifies as a “regular-way” trade and the associated commitment qualifies for an exemption from the accounting guidance applicable to derivative instruments. A regular-way trade is an investment security purchase or sale transaction that is expected to settle within the period of time following the trade date that is prevalent or traditional for that specific type of security. Any amounts payable or receivable for unsettled security trades are recorded as “sold securities receivable” or “purchased securities payable” in the consolidated balance sheets.

Interest Income Recognition for Investments in Agency MBS and Mortgage Loans of a Consolidated VIE

The Company recognizes interest income for its investments in agency MBS and mortgage loans of a consolidated variable interest entity (“VIE”) by applying the “interest method” permitted by GAAP, whereby purchase premiums and discounts are amortized and accreted, respectively, as an adjustment to contractual interest income accrued at each investment’s stated interest rate. The interest method is applied at the individual instrument level based upon each instrument’s effective interest rate. The Company calculates each instrument’s effective interest rate at the time of purchase or initial recognition by solving for the discount rate that equates the present value of that instrument's remaining contractual cash flows (assuming no principal prepayments) to its purchase cost. Because each instrument’s effective interest rate does not reflect an estimate of future prepayments, the Company refers to this manner of applying the interest method as the “contractual effective interest method.” When applying the contractual effective interest method to its investments in agency MBS and mortgage loans of a consolidated VIE, as principal prepayments occur, a proportional amount of the unamortized premium or unaccreted discount is recognized in interest income such that the contractual effective interest rate on any remaining security or loan balance is unaffected.

For mortgage loans of a consolidated VIE, the Company ceases the accrual of interest income (i.e., places the loan in non-accrual status) when it believes collectability of principal and interest in full is not reasonably assured, which generally occurs when a loan is three or more monthly payments past due, unless the loan is well secured and in the process of collection based upon an individual loan assessment.  When a loan is placed in non-accrual status, all accrued but uncollected contractual interest as well as any discount accreted during the period of delinquency are reversed.  While a loan is in non-accrual status, the Company recognizes interest income only when interest payments occur.

Interest Income Recognition for Investments in Mortgage Credit Securities and MSR Financing Receivables

The Company recognizes interest income for its investments in mortgage credit securities and MSR financing receivables by applying the prospective level-yield methodology required by GAAP for financial assets that are either not of high credit quality at the time of acquisition or can be contractually prepaid or otherwise settled in such a way that the Company would not recover substantially all of its recorded investment.  The amount of periodic interest income recognized is determined by applying the investment’s effective interest rate to its amortized cost basis (or “reference amount”). At the time of acquisition, the investment’s effective interest rate is calculated by solving for the single discount rate that equates the present value of the Company’s best estimate of the amount and timing of the cash flows expected to be collected from the investment to its purchase cost. To prepare its best estimate of cash flows expected to be collected, the Company develops a number of assumptions about the future performance of the pool of mortgage loans that serve as collateral for its investment, including assumptions about the timing and amount of prepayments and credit losses.  In each subsequent quarterly reporting period, the amount and timing of cash flows expected to be collected from the investment are re-estimated based upon current information and events. The following table provides a description of how periodic changes in the estimate of cash flows expected to be collected affect interest income recognition prospectively for investments in mortgage credit securities and MSR financing receivables:

Scenario:	Effect on Interest Income Recognition for Investments in Mortgage Credit Securities and MSR Financing Receivables:
A positive change in cash flows occurs. Actual cash flows exceed prior estimates and/or a positive change occurs in the estimate of expected remaining cash flows.	A revised effective interest rate is calculated and applied prospectively such that the positive change in cash flows will be recognized as incremental interest income over the remaining life of the investment.
	The amount of periodic interest income recognized over the remaining life of the investment will be reduced accordingly. Generally, the investment’s effective interest rate is reduced accordingly and applied on a prospective basis.  However, if the revised effective interest rate is negative, the investment’s existing effective interest rate is retained while the reference amount to which the existing effective interest rate will be prospectively applied is reduced to the present value of cash flows expected to be collected, discounted at the investment’s existing effective interest rate.
An adverse change in cash flows occurs. Actual cash flows fall short of prior estimates and/or an adverse change occurs in the estimate of expected remaining cash flows.

Note 3. Investments in Agency MBS

The Company has elected to classify its investments in agency MBS as trading securities.  Accordingly, the Company’s investments in agency MBS are reported in the accompanying consolidated balance sheets at fair value.  As of September 30, 2021 and December 31, 2020, the fair value of the Company’s investments in agency MBS was $637,718 and $970,880, respectively. As of

8

September 30, 2021, all the Company’s investments in agency MBS represent undivided (or “pass-through”) beneficial interests in specified pools of fixed-rate mortgage loans.

All periodic changes in the fair value of agency MBS that are not attributed to interest income are recognized as a component of “investment gain (loss), net” in the accompanying consolidated statements of comprehensive income. The following table provides additional information about the gains and losses recognized as a component of “investment gain (loss), net” in the Company’s consolidated statements of comprehensive income for the periods indicated with respect to investments in agency MBS:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2021			2020			2021			2020
Net gains (losses) recognized in earnings for:

Total	$	(2,447	)	$	1,858		$	(24,532	)	$	29,784

The Company also invests in and finances fixed-rate agency MBS on a generic pool basis through sequential series of to-be-announced security transactions commonly referred to as “dollar rolls.” Dollar rolls are accounted for as a sequential series of derivative instruments. Refer to “Note 10. Derivative Instruments” for further information about dollar rolls.

Note 4. Investments in Mortgage Credit Securities

The Company has elected to classify its investments in mortgage credit securities as trading securities.  Accordingly, the Company’s investments in mortgage credit securities are reported in the accompanying consolidated balance sheets at fair value.  As of September 30, 2021 and December 31, 2020, the fair value of the Company’s investments in mortgage credit securities was $25,477 and $26,660, respectively.  As of September 30, 2021, the Company’s investments in mortgage credit securities primarily consist of non-agency MBS collateralized by pools of residential mortgage loans, business purpose residential mortgage loans or smaller balance commercial mortgage loans.

All periodic changes in the fair value of mortgage credit securities that are not attributed to interest income are recognized as a component of “investment gain (loss), net” in the accompanying consolidated statements of comprehensive income. The following table provides additional information about the gains and losses recognized as a component of “investment gain (loss), net” in the Company’s consolidated statements of comprehensive income for the periods indicated with respect to investments in mortgage credit securities:

Note 5. Loans Held for Investment

As of September 30, 2021 and December 31, 2020, the Company held loans secured by first lien positions in commercial real estate with an aggregate outstanding principal outstanding principal balance of $29,800 and $45,000, respectively.  

As of September 30, 2021, the Company held a loan secured by a first lien position in healthcare facilities and guaranteed by the operator of the facilities with an outstanding principal balance of $29,800 that was purchased by the Company at par in April 2021.  The loan bears interest at a floating note rate equal to one-month LIBOR plus 5.50%.  The maturity date of the loan is March 23, 2022 with a one-year extension available at the option of the borrower.  The loan has monthly principal amortization based upon a 30-year amortization schedule with the remaining principal balance due at loan maturity.

As of December 31, 2020, the Company held a loan secured by a first lien position in healthcare facilities and guaranteed by the operator of the facilities with an outstanding principal balance of $45,000.  In July 2021, the Company received full repayment of

9

its loan investment.  The loan bore interest at a floating note rate equal to one-month LIBOR plus 4.25% with a LIBOR floor of 2.00%.  The maturity date of the loan was December 31, 2021 with a one-year extension available at the option of the borrower.  The loan had an initial interest-only period of one year followed by principal amortization based upon a 30-year amortization schedule beginning in 2021 with the remaining principal balance due at loan maturity.  

The Company has elected to account for its loans held for investment at fair value on a recurring basis with periodic changes in fair value recognized as a component of “investment gain (loss), net” in the accompanying consolidated statements of comprehensive income.  As of September 30, 2021 and December 31, 2020, the Company’s investments were $29,800 and $45,000, respectively, at fair value.  The Company recognizes interest income on its loan investments based upon the contractual note rate of the loans.

As of September 30, 2021, the Company was party to a participation agreement pursuant to which the Company has committed to fund up to $30,000 of a $130,000 revolving credit facility that matures on July 7, 2024.  Under the terms of the participation agreement, the Company funds the last $30,000 of advances under the revolving credit facility.  Any draws under the revolving credit facility bear interest at one-month LIBOR plus 3.75% with a LIBOR floor of 1.00% and are secured by a first lien on all accounts receivable and a second lien on all other assets of the borrower.  The borrower is also required to pay an unused commitment fee of 0.50%.  As of September 30, 2021, the Company’s unfunded commitment was $30,000.

Note 6. Investments in MSR Financing Receivables

The Company does not hold the requisite licenses to purchase or hold MSRs directly.  However, the Company has entered into agreements with a licensed, GSE approved residential mortgage loan servicer that enable the Company to garner the economic return of an investment in an MSR purchased by the mortgage servicing counterparty through an MSR financing transaction.  Under the terms of the arrangement, for an MSR acquired by the mortgage servicing counterparty (i) the Company purchases the “excess servicing spread” from the mortgage servicer counterparty, entitling the Company to monthly distributions of the servicing fees collected by the mortgage servicing counterparty in excess of 12.5 basis points per annum (and to distributions of corresponding proceeds of sale of the MSRs), and (ii) the Company funds the balance of the MSR purchase price to the parent company of the mortgage servicing counterparty and, in exchange, has an unsecured right to payment of certain amounts determined by reference to the MSR, generally equal to the servicing fee revenue less the excess servicing spread and the costs of servicing (and to distributions of corresponding proceeds of sale of the MSRs), net of fees earned by the mortgage servicing counterparty and its affiliates including an incentive fee equal to a percentage of the total return of the MSR in excess of a hurdle rate of return.  At the Company’s election, the mortgage servicing counterparty could utilize leverage on the MSRs that are subject to the Company’s MSR financing receivables to finance the purchase of additional MSRs to increase potential returns to the Company.   Under the arrangement, the Company is obligated to provide funds to the mortgage servicing counterparty to fund its advances of delinquent payments on the serviced pool of mortgage loans with the mortgage servicing counterparty required to return to the Company any subsequent servicing advances collected.  The Company has committed to invest a total minimum of $50,000 in capital with the counterparty with $25,000 of the minimum commitment expiring on December 31, 2023 and $25,000 of the minimum commitment expiring on April 1, 2024.

Under GAAP, the Company accounts for transactions executed under its arrangement as financing transactions and reflects the associated financing receivables in the line item “MSR financing receivables” on its consolidated balance sheets.  The Company has elected to account for its MSR financing receivables at fair value with changes in fair value that are not attributed to interest income recognized as a component of “investment gain (loss), net” in the accompanying consolidated statements of comprehensive income.  As described in further detail in “Note 2. Summary of Significant Accounting Policies,” the Company recognizes interest income for MSR financing receivables by applying the prospective level-yield methodology required by GAAP for financial assets that are either not of high credit quality at the time of acquisition or can be contractually prepaid or otherwise settled in such a way that the Company would not recover substantially all of its recorded investment.

As of September 30, 2021 and December 31, 2020, the fair value of the Company’s investments in MSR financing receivables was $112,834 and $9,346, respectively. The following table presents activity related to the carrying value of the Company’s investments in MSR financing receivables for the periods indicated:

10

	Three Months Ended September 30, 2021			Nine Months Ended September 30, 2021
Balance at period beginning	$	74,652		$	9,346
Capital investments		35,601			95,223
Capital distributions		(3,816	)		(3,816	)
Accretion of interest income		1,945			3,693
Changes in valuation inputs and assumptions		4,452			8,388
Balance at period end	$	112,834		$	112,834

Note 7. Investments in Single-Family Residential Properties

The Company is party to an agreement with a third-party investment firm to identify, acquire and manage investments in SFR properties on behalf of the Company.  Under the terms of the agreement, the Company has committed to fund up to $50,000 of capital to fund the acquisition of SFR properties.  Under the terms of the agreement, the Company is obligated to pay the third-party firm a minimum fee plus an incentive fee equal to a percentage of the total investment return in excess of a hurdle rate of return.  Under the terms of the agreement, if the Company were to terminate the commitment, the Company would incur termination fee equal to a fixed amount less inception to date minimum fees paid to the third-party firm.

The Company’s investments in SFR properties are initially recognized on the settlement date of their acquisition at cost.  The Company allocates the initial acquisition cost of each property to land and building on the basis of their relative fair values at the time of acquisition.  To determine the relative fair value of land and building at the time of acquisition, the Company uses available market data, such as property specific county tax assessment records.

Subsequent to the acquisition of a property, expenditures which improve or extend the life of the property are capitalized as a component of the property’s cost basis.  Expenditures for ordinary maintenance and repairs are recognized as an expense as incurred and are reported as a component of “single-family property operating expenses” in the Company’s consolidated statements of comprehensive income.

The Company subsequently recognizes depreciation of each property’s buildings and capitalized improvements over the expected useful lives of those assets.  The Company calculates depreciation on a straight-line basis over a useful life of 27.5 years for buildings and useful lives ranging from five to 27.5 years for capitalized improvements.  The Company reports depreciation expense as a component of “single-family property operating expenses” in the Company’s consolidated statements of comprehensive income.

As of September 30, 2021, the Company had investments in 33 SFR properties for a total cost of $9,419, all of which were acquired in September 2021.  During the three and nine months ended September 30, 2021, the Company recognized $12 of depreciation expense related to its SFR properties.  The following table summarizes the Company’s net carrying amount of its SFR properties by component as of the dates indicated:

	September 30, 2021			December 31, 2020
Investments in single-family residential real estate:
Land	$	1,553		$	—
Buildings and improvements		7,866			—
Investments in single-family residential real estate, at cost		9,419			—
Less: accumulated depreciation		(12	)		—
Investments in single-family residential real estate, net	$	9,407		$	—

As of September 30, 2021, the Company had commitments to acquire 75 SFR properties for an aggregate purchase price of $19,949.

Note 8. Consolidation of Variable Interest Entities

The vehicles that issue the Company’s investments in securitized mortgage assets are considered VIEs. The Company is required to consolidate any VIE in which it holds a variable interest if it determines that it holds a controlling financial interest in the VIE and is, therefore, determined to be the primary beneficiary of the VIE.  The Company is determined to be the primary beneficiary of a VIE in which it holds a variable interest if it both (i) holds the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.  The economic performance of the trusts that issue the Company’s investments in securitized mortgage assets is most significantly impacted by the performance of the mortgage loans that are held by the trusts.  The party that is determined to have the most power to direct the loss mitigation actions that are taken with respect to delinquent or otherwise troubled mortgage loans held by the trust is, therefore, deemed to hold the most power to direct the activities that most significantly impact the trust’s economic performance.  As a passive investor, the Company does not have the power to direct the loss mitigation activities of most of the trusts that have issued its securitized mortgage assets.  

11

On September 30, 2020, the Company acquired for $10,693 an investment that represents a majority interest in the first loss position of a securitized pool of business purpose residential mortgage loans. As majority holder of the first loss position, the Company is required to approve any material loss mitigation action proposed by the servicer with respect to a troubled loan.  The Company also has the option (but not the obligation) to purchase delinquent loans from the trust.  As a result of these contractual rights, the Company determined that it is the party with the most power to direct the loss mitigation activities and, therefore, the economic performance of the trust.  As holder of the majority of the first loss position issued by the trust, the Company has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the trust.  Accordingly, the Company determined that it is the primary beneficiary of the trust and consolidated the trust’s assets and liabilities owed to third parties onto its consolidated balance sheets.  The carrying values of the assets and liabilities of the consolidated VIE, net of elimination entries, are as follows as of the dates indicated:

	September 30, 2021			December 31, 2020
Restricted cash of consolidated VIE (1)	$	3,267		$	11,169
Mortgage loans of consolidated VIE, at fair value		16,516			93,283
Interest receivable of consolidated VIE		67			545
Secured debt of consolidated VIE, at fair value		(7,350	)		(93,627	)
Interest payable of consolidated VIE		(52	)		(321	)
Investment in consolidated VIE	$	12,448		$	11,049

<sup>(1)</sup> Restricted cash represents cash collected by the trust that must be used solely to satisfy the liabilities of the VIE in the month following collection.

The pool of mortgage loans and the third-party held debt obligations of the consolidated VIE had aggregate unpaid principal balances of $17,108 and $7,367, respectively, as of September 30, 2021.  The trust is contractually entitled to receive monthly interest payments on each underlying mortgage loan net of a loan-specific servicing and asset management fee that is not remitted to the trust but is, rather, retained by the servicer.  As of September 30, 2021, the weighted average net note rate to which the VIE was entitled and the weighted average coupon rate of the debt obligations of the consolidated VIE were 6.05% and 4.99%, respectively.  The debt of the consolidated VIE has recourse solely to the assets of the VIE; it has no recourse to the general credit of the Company.

The pool of business purpose residential mortgage loans held by the consolidated VIE consists of fixed-rate, short-term, interest-only mortgage loans (with the full amount of principal due at maturity) made to professional real estate investors and are secured by first lien positions in non-owner occupied residential real estate.  The properties that secure these mortgage loans often require construction, repair or rehabilitation.  The repayment of the mortgage loans is often largely based on the ability of the borrower to sell the mortgaged property or to convert the property for rental purposes and obtain refinancing in the form of a longer-term loan.  Pursuant to the terms of certain of the mortgage loans, the borrower may draw upon a specified amount of additional funds as needed in order to finance construction on, or the repair or rehabilitation of, the mortgaged property (referred to as a “construction draw”).  Pursuant to the terms of the securitization transaction, if the monthly principal repayments collected from the mortgage loan pool are insufficient to fund that month’s construction draws, such shortfall is to be funded by the holders of the first loss position on a pro rata basis.  Any construction draws funded by holders of the first loss position accrue interest at the net note rate of the mortgage loan.  The repayment of any construction draws funded by holders of the first loss position takes priority over the senior debt securities with respect to the cash flows collected from the mortgage loan pool in the following month.  As of September 30, 2021, the aggregate unfunded construction draw balance commitment attributable to the Company’s subordinate debt security investment was $1,306.

The Company has elected to account for the mortgage loans and debt of the consolidated VIE at fair value with changes in fair value that are not attributed to interest income or interest expense, respectively, recognized as a component of “investment gain (loss), net” in the accompanying consolidated statements of comprehensive income.

As described in further detail in “Note 2. Summary of Significant Accounting Policies,” the Company recognizes interest income for the mortgage loans of the consolidated VIE by applying the “interest method” permitted by GAAP, whereby the discount

12

recognized at the initial recognition of each loan is accreted as an adjustment to contractual interest income accrued at the loan’s stated interest rate. The Company ceases the accrual of interest income for a mortgage loan (i.e., places the loan in non-accrual status) when it believes collectability of principal and interest in full is not reasonably assured, which generally occurs when a loan is three or more monthly payments past due, unless the loan is well secured and in the process of collection based upon an individual loan assessment.  Upon placing a loan in non-accrual status, any previously accrued but uncollected interest is derecognized and a corresponding reduction to current period interest income is recorded.  The following table presents information about the accrual status of the mortgage loans of the consolidated VIE as of September 30, 2021:

	Aggregate Fair Value		Aggregate Unpaid Principal Balance		Difference
Less than 90 days past due and in accrual status	$	9,516	$	9,857	$	(341	)
90 days or more past due and in non-accrual status		7,000		7,251		(251	)
Total mortgage loans of consolidated VIE	$	16,516	$	17,108	$	(592	)

Note 9. Borrowings

Repurchase Agreements

The Company finances the purchase of mortgage investments through repurchase agreements, which are accounted for as collateralized borrowing arrangements. In a repurchase transaction, the Company sells a mortgage investment to a counterparty under a master repurchase agreement in exchange for cash and concurrently agrees to repurchase the same asset at a future date in an amount equal to the cash initially exchanged plus an agreed-upon amount of interest. Mortgage investments sold under agreements to repurchase remain on the Company’s consolidated balance sheets because the Company maintains effective control over such assets throughout the duration of the arrangement. Throughout the contractual term of a repurchase agreement, the Company recognizes a “repurchase agreement” liability on its consolidated balance sheets to reflect the obligation to repay to the counterparty the proceeds received upon the initial transfer of the mortgage investment. The difference between the proceeds received by the Company upon the initial transfer of the mortgage investment and the contractually agreed-upon repurchase price is recognized as interest expense ratably over the term of the repurchase arrangement.

Amounts borrowed pursuant to repurchase agreements are equal in value to a specified percentage of the fair value of the pledged collateral. The Company retains beneficial ownership of the pledged collateral throughout the term of the repurchase agreement. The counterparty to the repurchase agreements may require that the Company pledge additional securities or cash as additional collateral to secure borrowings when the value of the collateral declines.

The Company’s MBS repurchase agreement arrangements generally carry a fixed rate of interest and are short-term in nature with contract durations generally ranging from 30 to 60 days, but may be as short as one day or as long as one year.  The Company’s mortgage loan repurchase agreement arrangement has a maturity date of August 25, 2022 and an interest rate that resets monthly at a rate equal to one-month LIBOR plus 2.50%.   Under the terms of the Company’s mortgage loan repurchase agreement, the Company may request extensions of the maturity date of the agreement for up to 364 days, subject to the lender’s approval.

13

As of September 30, 2021 and December 31, 2020, the Company had no amount at risk with a single repurchase agreement counterparty or lender greater than 10% of equity. The following table provides information regarding the Company’s outstanding repurchase agreement borrowings as of the dates indicated:

During the nine months ended September 30, 2021, the Company repurchased $7 in principal balance of Senior Notes due 2023 for a purchase price of $7. There were no repurchases of outstanding long-term unsecured debentures during the three months ended September 30, 2021.  During the three and nine months ended September 30, 2020, the Company repurchased $820 and $1,066 in principal balance of Senior Notes due 2023 for a purchase price of $782 and $1,012, respectively.  During the three and nine months ended September 30, 2020, the Company repurchased $153 and $331 in principal balance of Senior Notes due 2025 for a purchase price of $140 and $296, respectively.

On July 15, 2021, the Company completed a public offering of $37,750 of 6.00% Senior Notes due 2026 and received net proceeds of $36,570 after deducting underwriter discounts.  On August 6, 2021, the Company redeemed all $23,821 in principal amount of its outstanding Senior Notes due 2023 at a redemption price of 100% of the principal amount plus unpaid interest thereon.

The Senior Notes due 2025 and the Senior Notes due 2026 are publicly traded on the New York Stock Exchange under the ticker symbols “AIC” and “AAIN,” respectively. The Senior Notes due 2025 and Trust Preferred Debt may be redeemed in whole or in part at any time and from time to time at the Company’s option at a redemption price equal to the principal amount plus accrued and unpaid interest. The Senior Notes due 2026 may be redeemed in whole or in part at any time and from time to time at the Company’s option on or after August 1, 2023 at a redemption price equal to the principal amount plus accrued and unpaid interest.  The indenture governing the Senior Notes contains certain covenants, including limitations on the Company’s ability to merge or consolidate with other entities or sell or otherwise dispose of all or substantially all of the Company’s assets.

Long-Term Secured Debt

On September 28, 2021, McLean SFR Investment, LLC (“McLean SFR”), a wholly-owned subsidiary of Arlington Asset, entered into a loan agreement with a third-party lender to fund McLean SFR’s purchases of SFR properties.  Under the terms of the loan agreement, loan advances may be drawn up to 74% of the fair value of eligible SFR properties up to a maximum loan amount of $150,000.  Advances under the loan agreement may be drawn during the advance period, which ends on the earlier of the date the outstanding principal balance equals the maximum loan amount or March 28, 2023.  The outstanding principal balance is due on October 9, 2026 and advances under the loan agreement bear interest at a fixed rate of 2.76%.  As of September 30, 2021, there were no advances outstanding under the loan agreement.

Through September 28, 2024, the outstanding principal balance may be prepaid in an amount equal to the excess of (i) the sum of the present value of all remaining scheduled payments of principal and interest on the principal amount of the loan being prepaid discounted using a U.S. Treasury rate over (ii) the outstanding principal balance of the loan.  Subsequent to September 28, 2024, the outstanding principal balance may be prepaid in an amount equal to the outstanding principal balance plus accrued interest.

The loan is secured by a first priority interest in all the assets of McLean SFR and a first priority pledge of the equity interest of McLean SFR. If the outstanding principal balance of the loan is greater than 74% of the fair value of the eligible collateral, McLean SFR is required to either pledge additional collateral or prepay the loan in an amount so that the outstanding principal balance does not exceed 74% of the fair value of the eligible collateral.  Under the terms of the loan agreement, if McLean SFR does not maintain a minimum debt service coverage ratio for a specified time period, then all available cash of McLean SFR will be held as additional collateral for the loan amount until the minimum debt service coverage ratio is met.  The obligations under the loan agreement may become recourse to Arlington Asset upon the occurrence of certain enumerated acts committed by McLean SFR or Arlington Asset.  The loan agreement contains a minimum net worth financial covenant of Arlington Asset.

Note 10. Derivative Instruments

In the normal course of its operations, the Company is a party to financial instruments that are accounted for as derivative instruments. Derivative instruments are recorded at fair value as either “derivative assets” or “derivative liabilities” in the consolidated balance sheets, with all periodic changes in fair value reflected as a component of “investment gain (loss), net” in the consolidated statements of comprehensive income. Cash receipts or payments related to derivative instruments are classified as investing activities within the consolidated statements of cash flows.

Types and Uses of Derivative Instruments

Interest Rate Hedging Instruments

The Company is party to interest rate hedging instruments that are intended to economically hedge changes, attributable to changes in benchmark interest rates, in certain MBS fair values and future interest cash flows on the Company’s short-term financing arrangements. Interest rate hedging instruments may include centrally cleared interest rate swaps, exchange-traded instruments, such as U.S. Treasury note futures, Eurodollar futures, interest rate swap futures and options on futures, and non-exchange-traded

15

instruments such as options on agency MBS. While the Company uses its interest rate hedging instruments to economically hedge a portion of its interest rate risk, it has not designated such contracts as hedging instruments for financial reporting purposes.

The Company exchanges cash “variation margin” with the counterparties to its interest rate hedging instruments at least on a daily basis based upon daily changes in fair value as measured by the Chicago Mercantile Exchange (“CME”), the central clearinghouse through which those instruments are cleared. In addition, the CME requires market participants to deposit and maintain an “initial margin” amount which is determined by the CME and is generally intended to be set at a level sufficient to protect the CME from the maximum estimated single-day price movement in that market participant’s contracts. However, futures commission merchants may require “initial margin” in excess of the CME’s requirement.  Receivables recognized for the right to reclaim cash initial margin posted in respect of interest rate hedging instruments are included in the line item “deposits” in the accompanying consolidated balance sheets.

The daily exchange of variation margin associated with a centrally cleared or exchange-traded hedging instrument is legally characterized as the daily settlement of the instrument itself, as opposed to a pledge of collateral. Accordingly, the Company accounts for the daily receipt or payment of variation margin associated with its interest rate swaps and futures as a direct reduction to the carrying value of the derivative asset or liability, respectively. The carrying amount of interest rate swaps and futures reflected in the Company’s consolidated balance sheets is equal to the unsettled fair value of such instruments; because variation margin is exchanged on a one-day lag, the unsettled fair value of such instruments generally represents the change in fair value that occurred on the last day of the reporting period.

To-Be-Announced Agency MBS Transactions, Including “Dollar Rolls”

In addition to interest rate hedging instruments that are used for interest rate risk management, the Company is a party to derivative instruments that economically serve as investments, such as forward commitments to purchase fixed-rate “pass-through” agency MBS on a non-specified pool basis, which are known as to-be-announced (“TBA”) securities. A TBA security is a forward commitment for the purchase or sale of a fixed-rate agency MBS at a predetermined price, face amount, issuer, coupon, and stated maturity for settlement on an agreed upon future date. The specific agency MBS that will be delivered to satisfy the TBA trade is not known at the inception of the trade. The specific agency MBS to be delivered is determined 48 hours prior to the settlement date. The Company accounts for TBA securities as derivative instruments because the Company cannot assert that it is probable at inception and throughout the term of an individual TBA commitment that its settlement will result in physical delivery of the underlying agency MBS, or the individual TBA commitment will not settle in the shortest time period possible.

The Company’s agency MBS investment portfolio includes net purchase (or “net long”) positions in TBA securities, which are primarily the result of executing sequential series of “dollar roll” transactions. The Company executes dollar roll transactions as a means of investing in and financing non-specified fixed-rate agency MBS. Such transactions involve effectively delaying (or “rolling”) the settlement of a forward purchase of a TBA agency MBS by entering into an offsetting sale with the same counterparty prior to the settlement date, net settling the “paired-off” positions in cash, and contemporaneously entering, with the same counterparty, another forward purchase of a TBA agency MBS of the same characteristics for a later settlement date. TBA securities purchased for a forward settlement month are generally priced at a discount relative to TBA securities sold for settlement in the current month. This discount, often referred to as the dollar roll “price drop,” reflects compensation for the net interest income (interest income less financing costs) that is foregone as a result of relinquishing beneficial ownership of the MBS for the duration of the dollar roll (also known as “dollar roll income”). By executing a sequential series of dollar roll transactions, the Company is able to create the economic experience of investing in an agency MBS, financed with a repurchase agreement, over a period of time. Forward purchases and sales of TBA securities are accounted for as derivative instruments in the Company’s financial statements. Accordingly, dollar roll income is recognized as a component of “investment gain (loss), net” along with all other periodic changes in the fair value of TBA commitments.

In addition to transacting in net long positions in TBA securities for investment purposes, the Company may also, from time to time, transact in net sale (or “net short”) positions in TBA securities for the purpose of economically hedging a portion of the sensitivity of the fair value of the Company’s investments in agency MBS to changes in interest rates.

In addition to TBA transactions, the Company may, from time to time, enter into commitments to purchase or sell specified agency MBS that do not qualify as regular-way security trades. Such commitments are also accounted for as derivative instruments.

Under the terms of commitments to purchase or sell TBAs or specified agency MBS, the daily exchange of variation margin may occur based on changes in the fair value of the underlying agency MBS if a party to the transaction demands it. Receivables recognized for the right to reclaim cash collateral posted by the Company in respect of agency MBS purchase or sale commitments is included in the line item “deposits” in the accompanying consolidated balance sheets. Liabilities recognized for the obligation to

16

return cash collateral received by the Company in respect of agency MBS purchase or sale commitments is included in the line item “other liabilities” in the accompanying consolidated balance sheets.

U.S. Treasury Note Futures

The Company may purchase (“long”) or sell (“short”) exchange-traded U.S. Treasury note futures with the objective of economically hedging a portion of its interest rate risk. Upon the maturity date of these futures contracts, the Company has the option to either net settle each contract in cash in an amount equal to the difference between the then-current fair value of the underlying U.S. Treasury note and the contractual sale price inherent to the futures contract, or to physically settle the contract by purchasing or delivering the underlying U.S. Treasury note.

As of September 30, 2021 and December 31, 2020, the Company had no outstanding positions of U.S. Treasury note futures.

Options on U.S. Treasury Note Futures

The Company may purchase or sell exchange-traded options on U.S. Treasury note futures contracts with the objective of economically hedging a portion of the sensitivity of its investments in agency MBS to significant changes in interest rates. The

17

Company may purchase put or call options which provide the Company with the right to sell to counterparty or purchase from a counterparty U.S. Treasury note futures, and the Company may also write put or call options that provide a counterparty with the option to sell to the Company or buy from the Company U.S. Treasury note futures. The options may be exercised at any time prior to their expiry, and if exercised, may be net settled in cash or through physical receipt or delivery of the underlying futures contracts.

As of September 30, 2021 and December 31, 2020, the Company had no outstanding options on U.S. Treasury note futures contracts.

Note 11. Offsetting of Financial Assets and Liabilities

The agreements that govern certain of the Company’s derivative instruments and collateralized short-term financing arrangements provide for a right of setoff in the event of default or bankruptcy with respect to either party to such transactions. The Company presents derivative assets and liabilities as well as collateralized short-term financing arrangements on a gross basis.

Receivables recognized for the right to reclaim cash initial margin posted in respect of interest rate derivative instruments are included in the line item “deposits” in the accompanying consolidated balance sheets.

The daily exchange of variation margin associated with a centrally cleared or exchange-traded derivative instrument is legally characterized as the daily settlement of the derivative instrument itself, as opposed to a pledge of collateral. Accordingly, the Company accounts for the daily receipt or payment of variation margin associated with its interest rate swaps and futures as a direct reduction to the carrying value of derivative asset or liability, respectively. The carrying amount of interest rate swaps and futures reflected in the Company’s consolidated balance sheets is equal to the unsettled fair value of such instruments; because variation margin is exchanged on a one-day lag, the unsettled fair value of such instruments generally represents the change in fair value that occurred on the last day of the reporting period.

Note 12. Fair Value Measurements

Fair Value of Financial Instruments

The accounting principles related to fair value measurements define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial Accounting Standards Board Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, giving the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3) as described below:

Level 1 Inputs -  Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible by the Company at the measurement date;

Level 2 Inputs -  Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and

Level 3 Inputs -  Unobservable inputs for the asset or liability, including significant judgments made by the Company about the assumptions that a market participant would use.

The Company measures the fair value of the following assets and liabilities:

Mortgage investments

Agency MBS - The Company’s investments in agency MBS are classified within Level 2 of the fair value hierarchy. Inputs to fair value measurements of the Company’s investments in agency MBS include price estimates obtained from third-party pricing services.  In determining fair value, third-party pricing services use a market approach. The inputs used in the fair value measurements performed by the third-party pricing services are based upon readily observable transactions for securities with similar characteristics (such as issuer/guarantor, coupon rate, stated maturity, and collateral pool characteristics) occurring on the measurement date. The Company makes inquiries of the third-party pricing sources and reviews their documented valuation methodologies to understand the significant inputs and assumptions used to determine prices. The Company reviews the various third-party fair value estimates and performs procedures to validate their reasonableness, including comparison to recent trading activity for similar securities and an overall review for consistency with market conditions observed as of the measurement date.

Mortgage credit securities – The Company’s investments in residential MBS and commercial MBS are classified within Level 2 of the fair value hierarchy. Inputs to fair value measurements of the Company’s investments in residential and commercial MBS include quoted prices for similar assets in recent market transactions and estimates obtained from third-party pricing sources including pricing services and dealers. In determining fair value, third-party pricing sources use a market approach. The inputs used in the fair value measurements performed by third-party pricing sources are based upon observable transactions for securities with similar characteristics. The Company reviews the third-party fair value estimates and performs procedures to validate their reasonableness, including comparisons to recent trading activity observed for similar securities as well as an internally derived discounted future cash flow measurement.

The Company’s first loss position in a securitized pool of business-purpose residential mortgage loans is classified within Level 3 of the fair value hierarchy.  To measure the fair value of this investment, the Company uses an income approach by preparing an estimate of the present value of the amount and timing of the cash flows expected to be collected from the security over its expected remaining life.  To prepare the estimate of cash flows expected to be collected, the Company uses significant judgment to develop assumptions about the future performance of the pool of mortgage loans that serve as collateral, including assumptions about the timing and amount of credit losses and prepayments.  The significant unobservable inputs to the fair value measurement include the estimated rate of default and loss-given-default for the underlying pool of mortgage loans as well as the discount rate, which represents a market participant’s current required rate of return for a similar instrument.  The following table presents the significant unobservable inputs to the fair value measurement of the Company’s non-agency MBS secured by business-purpose residential mortgage loans as of the periods indicated:

	September 30, 2021			December 31, 2020
Annualized default rate		35.0	%		12.0	%
Loss-given-default		25.0	%		40.0	%

Loans – The Company’s commercial mortgage loan investment is classified within Level 3 of the fair value hierarchy.  To measure the fair value of its mortgage loan investment, the Company uses an income approach by preparing an estimate of the present value of the expected future cash flows of the loan over their expected remaining life, discounted at a current market rate.  The significant unobservable inputs to the fair value measurement of the Company’s mortgage loan investment is the estimated probability of default and the discount rate, which is based on current market yields and interest rate spreads for a similar loan.  As of September 30, 2021, the estimated probability of default and discount rate for the Company’s mortgage loan investment were 0%, and 5.6%, respectively.  As of December 31, 2020, the estimated probability of default and discount rate for the Company’s mortgage loan investment were 0% and 6.3%, respectively.

Mortgage loans and secured debt of consolidated VIE – The Company has elected to apply a fair value measurement practical expedient permitted by GAAP to measure the fair value of the mortgage loans and debt obligations of its consolidated VIE.  The fair value measurement practical expedient is permitted to be applied to consolidated “collateralized financing entities,” which are VIEs for which the financial liabilities of the VIE have contractual recourse solely to the financial assets of the VIE.  Pursuant to the practical expedient, the Company measures the fair value of both the mortgage loans and the debt obligations of its consolidated VIE based upon the fair value of the debt obligations of the VIE, as the fair value of the debt securities issued by the VIE is more observable to the Company than the fair value of the underlying mortgage loans.

The senior debt obligations of the consolidated VIE are classified within Level 2 of the fair value hierarchy.  Inputs to fair value measurements of the senior debt obligations of the consolidated VIE include quoted prices for similar assets in recent market transactions and estimates obtained from third-party pricing sources including pricing services and dealers. In determining fair value, third-party pricing sources use a market approach. The inputs used in the fair value measurements performed by third-party pricing sources are based upon observable transactions for securities with similar characteristics.

The subordinate debt obligation and the mortgage loans of the consolidated VIE are classified within Level 3 of the fair value hierarchy.  To measure the fair value of the subordinate debt obligation of the consolidated VIE, the Company uses an income approach by preparing an estimate of the present value of the amount and timing of the cash flows expected to be collected from the security over its expected remaining life.  To prepare the estimate of cash flows expected to be collected, the Company uses significant judgment to develop assumptions about the future performance of the pool of business-purpose residential mortgage loans that serve as collateral, including assumptions about the timing and amount of credit losses and prepayments.  The significant unobservable inputs to the fair value measurement include the estimated rate of default and loss-given-default for the underlying pool of mortgage loans as well as the discount rate, which represents a market participant’s current required rate of return for a similar instrument.  The following table presents the significant unobservable inputs to the fair value measurement of the subordinate debt obligation as of the periods indicated:

	September 30, 2021			December 31, 2020
Annualized default rate		15.0	%		20.0	%
Loss-given-default		25.0	%		40.0	%
Discount rate		12.0	%		13.9	%

MSR financing receivables – The Company’s MSR financing receivables are classified within Level 3 of the fair value hierarchy.  The Company uses a nationally recognized, independent third-party mortgage analytics and valuation firm to estimate the fair value of the underlying MSRs from which the Company’s MSR financing receivables primarily derive their value. The third-party valuation firm estimates the fair value of the underlying MSRs using a discounted cash flow analysis using their proprietary prepayment models and market analysis.  The Company corroborates the third-party valuation firm’s estimate of the fair value of the underlying MSRs and evaluates the estimate for reasonableness.  The significant unobservable inputs to the fair value measurement of the underlying MSRs include the following:

• the discount rate, which represents a market participant’s current required rate of return for similar MSRs;

• expected rates of prepayment within the serviced pools of mortgage loans; and  

• annual per-loan cost of servicing.

The following table presents the significant unobservable inputs to the fair value measurement of the MSRs underlying the Company’s MSR financing receivables as of September 30, 2021:

	September 30, 2021
Discount rate		9.0	%
Annualized prepayment rate		10.2	%
Annual per-loan cost of servicing (current loans)	$	65.00

22

Pursuant to the Company’s MSR financing arrangements, upon the consummation of three-year performance periods ending December 31, 2023 and April 1, 2024, the Company’s mortgage servicer counterparty is entitled to an incentive fee payment equal to a percentage of the total return of the underlying MSRs in excess of a hurdle rate of return.  Accordingly, the fair value of the Company’s MSR financing receivables reflects the present value of any expected incentive fee payment that would be owed to its counterparty based upon the current fair value of the underlying MSRs.  As of September 30, 2021, the present value of the expected incentive fee payment reflected in fair value of the Company’s MSR financing receivables was $1,413.

As of December 31, 2020, the fair value of the Company’s MSR financing receivable was its transacted purchase price, which occurred on the measurement date.

Derivative instruments

Exchange-traded derivative instruments - Exchange-traded derivative instruments, which include U.S. Treasury note futures, Eurodollar futures, interest rate swap futures, and options on futures, are classified within Level 1 of the fair value hierarchy as they are measured using quoted prices for identical instruments in liquid markets.

Interest rate swaps - Interest rate swaps are classified within Level 2 of the fair value hierarchy. The fair values of the Company’s centrally cleared interest rate swaps are measured using the daily valuations reported by the clearinghouse through which the instrument was cleared. In performing its end-of-day valuations, the clearinghouse constructs forward interest rate curves (for example, three-month LIBOR or SOFR forward rates) from its specific observations of that day’s trading activity. The clearinghouse uses the applicable forward interest rate curve to develop a market-based forecast of future remaining contractually required cash flows for each interest rate swap. Each market-based cash flow forecast is then discounted using the SOFR curve (sourced from the Federal Reserve Bank of New York) to determine a net present value amount which represents the instrument’s fair value.

Forward-settling purchases and sales of TBA securities – Forward-settling purchases and sales of TBA securities are classified within Level 2 of the fair value hierarchy. The fair value of each forward-settling TBA contract is measured using price estimates obtained from a third-party pricing service, which are based upon readily observable transaction prices occurring on the measurement date for forward-settling contracts to buy or sell TBA securities with the same guarantor, contractual maturity, and coupon rate for delivery on the same forward settlement date as the commitment under measurement.

Other

Long-term unsecured debt - As of September 30, 2021 and December 31, 2020, the carrying value of the Company’s long-term unsecured debt was $85,901 and $73,027, respectively, net of unamortized debt issuance costs, and consists of Senior Notes and trust preferred debt issued by the Company. The Company’s estimate of the fair value of long-term unsecured debt is $84,795 and $69,904 as of September 30, 2021 and December 31, 2020, respectively. The Company’s Senior Notes, which are publicly traded on the New York Stock Exchange, are classified within Level 1 of the fair value hierarchy. Trust preferred debt is classified within Level 2 of the fair value hierarchy as the fair value is estimated based on the quoted prices of the Company’s publicly traded Senior Notes.

Investments in equity securities of publicly-traded companies – As of September 30, 2021 and December 31, 2020, the Company had investments in equity securities of publicly-traded companies at fair value of $5,544 and $10,821, respectively, which is included in the line item “other assets” in the accompanying consolidated balance sheets.  Investments in publicly traded stock are classified within Level 1 of the fair value hierarchy as their fair value is measured based on unadjusted quoted prices in active exchange markets for identical assets.

Investments in equity securities of non-public companies and investment funds – As of September 30, 2021 and December 31, 2020, the Company had investments in equity securities and investment funds measured at fair value of $7,143 and $6,869, respectively, which are included in the line item “other assets” in the accompanying consolidated balance sheets.

23

Investments in equity securities of non-public companies and investment funds are classified within Level 3 of the fair value hierarchy. The fair values of the Company’s investments in equity securities of non-public companies and investment funds are not readily determinable. Accordingly, the Company estimates fair value by estimating the enterprise value of the investee which it then allocates to the investee’s securities in the order of their preference relative to one another. To estimate the enterprise value of the investee, the Company uses traditional valuation methodologies based on income and market approaches, including the consideration of recent investments in, or tender offers for, the equity securities of the investee, a discounted cash flow analysis and a comparable guideline public company valuation. The primary unobservable inputs used in estimating the fair value of an equity security of a non-public company include (i) a stock price to net asset multiple for similar public companies that is applied to the entity’s net assets, (ii) a discount factor for lack of marketability and control, and (iii) a cost of equity discount rate, used to discount to present value the equity cash flows available for distribution and the terminal value of the entity. As of September 30, 2021, the stock price to net asset multiple for similar public companies, the discount factor for lack of marketability and control, and the cost of equity discount rate used as inputs were 95 percent, 15 percent, and 16 percent, respectively. As of December 31, 2020, the stock price to net asset multiple for similar public companies, the discount factor for lack of marketability and control, and the cost of equity discount rate used as inputs were 95 percent, 10 percent, and 15 percent, respectively. For its investments in investment funds, the Company estimates fair value based upon the investee’s net asset value per share.

Financial assets and liabilities for which carrying value approximates fair value - Cash and cash equivalents, restricted cash, deposits, receivables, repurchase agreements, payables, and other assets (aside from those previously discussed) and liabilities are generally reflected in the consolidated balance sheets at their cost, which, due to the short-term nature of these instruments and their limited inherent credit risk, approximates fair value.

Note 13. Income Taxes

The Company has elected to be taxed as a REIT under the Internal Revenue Code.  As a REIT, the Company is required to distribute annually 90% of its REIT taxable income. So long as the Company continues to qualify as a REIT, it will generally not be subject to U.S. Federal or state corporate income taxes on its taxable income to the extent that it distributes all of its annual taxable income to its shareholders on a timely basis. At present, it is the Company’s intention to distribute 100% of its taxable income, although the Company will not be required to do so. The Company intends to make distributions of its taxable income within the time limits prescribed by the Internal Revenue Code, which may extend into the subsequent taxable year.

As of September 30, 2021, the Company had net operating loss (“NOL”) carryforwards of $150,936 that can be used to offset future taxable ordinary income and reduce its REIT distribution requirements. NOL carryforwards totaling $14,588 expire in 2028 and NOL carryforwards totaling $136,348 have no expiration period. As of September 30, 2021, the Company had net capital loss (“NCL”) carryforwards of $180,948 that can be used to offset future net capital gains. The scheduled expirations of the Company’s NCL carryforwards are $66,862 in 2021, $3,763 in 2022 and $110,323 in 2023.

The Company and subsidiaries have made joint elections to treat certain subsidiaries as taxable REIT subsidiaries (“TRSs”).  In general, a TRS may hold assets and engage in activities that the Company cannot hold or engage in directly and generally may engage in any real estate or non-real estate related business.  As such, each of these TRSs is taxable as a C corporation and subject to federal, state and local income taxes based upon their taxable income. For the three and nine months ended September 30, 2021, the Company recognized a provision for income taxes of $436 and $758, respectively, on the pre-tax net income of its TRSs.

The Company recognizes uncertain tax positions in the financial statements only when it is more-likely-than-not that the position will be sustained upon examination by the relevant taxing authority based on the technical merits of the position. A position

25

that meets this standard is measured at the largest amount of benefit that will more-likely-than-not be realized upon settlement. A liability is established for differences between positions taken in a tax return and the financial statements. As of September 30, 2021 and December 31, 2020, the Company assessed the need for recording a provision for any uncertain tax position and has made the determination that such provision is not necessary.  If the Company were to incur income tax related interest and penalties, the Company’s policy is to classify them as a component of provision for income taxes.

Note 14. Earnings (Loss) Per Share

Basic earnings (loss) per share includes no dilution and is computed by dividing net income or loss applicable to common stock by the weighted-average number of common shares outstanding for the respective period. Diluted earnings per share includes the impact of dilutive securities such as unvested shares of restricted stock, restricted stock units, and performance share units. The following tables present the computations of basic and diluted earnings (loss) per share for the periods indicated:

	Three Months Ended September 30,					Nine Months Ended September 30,
(Shares in thousands)	2021			2020		2021			2020
Basic weighted-average common shares outstanding		31,927			34,655		32,720			35,990
Performance share units, unvested restricted stock units,    and unvested restricted stock		—			42		—			—
Diluted weighted-average common shares outstanding		31,927			34,697		32,720			35,990
Net (loss) income (attributable) available to common stock	$	(981	)	$	4,033	$	(15,526	)	$	(81,435	)
Basic (loss) earnings per common share	$	(0.03	)	$	0.12	$	(0.47	)	$	(2.26	)
Diluted (loss) earnings per common share	$	(0.03	)	$	0.12	$	(0.47	)	$	(2.26	)

 The diluted loss per share for the three months and nine months ended September 30, 2021 did not include the antidilutive effect of 315,576 and 312,371 shares of unvested shares of restricted stock, restricted stock units, and performance share units, respectively. The diluted loss per share for the nine months ended September 30, 2020 did not include the antidilutive effect of 65,208 shares of unvested shares of restricted stock, restricted stock units, and performance share units.

As of September 30, 2021, the Company had 1,623,242 shares of Series B Preferred stock available for sale under the preferred equity distribution agreement.

Shareholder Rights Agreement

On June 1, 2009, the Board of Directors approved a shareholder rights agreement (“Rights Plan”) and the Company’s shareholders approved the Rights Plan at its annual meeting of shareholders on June 2, 2010.  On April 9, 2018, the Board of Directors approved a first amendment to the Rights Plan (“First Amendment”) to extend the term for an additional three years and the Company’s shareholders approved the First Amendment at its annual meeting of shareholders on June 14, 2018.  

Under the terms of the Rights Plan, in general, if a person or group acquires or commences a tender or exchange offer for beneficial ownership of 4.9% or more of the outstanding shares of our Class A common stock upon a determination by our Board of Directors (an “Acquiring Person”), all of our other Class A and Class B common shareholders will have the right to purchase securities from us at a discount to such securities’ fair market value, thus causing substantial dilution to the Acquiring Person.

The Board of Directors adopted the Rights Plan in an effort to protect against a possible limitation on the Company’s ability to use its NOL carryforwards, NCL carryforwards, and built-in losses under Sections 382 and 383 of the Internal Revenue Code. The Company’s ability to use its NOLs, NCLs and built-in losses would be limited if it experienced an “ownership change” under Section 382 of the Internal Revenue Code. In general, an “ownership change” would occur if there is a cumulative change in the ownership of the Company’s common stock of more than 50% by one or more “5% shareholders” during a three-year period. The Rights Plan was adopted to dissuade any person or group from acquiring 4.9% or more of the Company’s outstanding Class A common stock, each, an Acquiring Person, without the approval of the Board of Directors and triggering an “ownership change” as defined by Section 382.

The Rights Plan, as amended, and any outstanding rights will expire at the earliest of (i) June 4, 2022, (ii) the time at which the rights are redeemed or exchanged pursuant to the Rights Plan, (iii) the repeal of Section 382 and 383 of the Internal Revenue Code or any successor statute if the Board of Directors determines that the Rights Plan is no longer necessary for the preservation of the applicable tax benefits, or (iv) the beginning of a taxable year to which the Board of Directors determines that no applicable tax benefits may be carried forward.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Unless the context otherwise requires or provides, references in this Quarterly Report on Form 10-Q to “we,” “us,” “our” and the “Company” refer to Arlington Asset Investment Corp. (“Arlington Asset”) and its subsidiaries. This discussion and analysis should be read in conjunction with our financial statements and accompanying notes included in Item 1 of this Quarterly Report on Form 10-Q, as well as our audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020.

The discussion of our consolidated financial condition and results of operations below may contain forward-looking statements. These statements, which reflect management’s beliefs and expectations, are subject to risks and uncertainties that may cause actual results to differ materially. For a discussion of the risks and uncertainties that may affect our future results, please see “Cautionary Statement About Forward-Looking Information” in Item 3 of Part I of this Quarterly Report on Form 10-Q and the risk factors included in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2020.

Our Company

We are an investment firm that focuses primarily on investing in mortgage related assets and residential real estate.  We may also invest in other asset classes that our management team believes may offer attractive risk adjusted returns outside the real estate or mortgage asset classes. Our investment capital is currently allocated between agency MBS, MSR related assets, mortgage credit investments and single-family residential (“SFR”) properties.

Our agency MBS consist of residential mortgage pass-through certificates for which the principal and interest payments are guaranteed by either a GSE, such as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or by a U.S. government agency, such as the Government National Mortgage Association (“Ginnie Mae”). Our mortgage credit investments generally include investments in mortgage loans secured by either residential or commercial real property or MBS collateralized by residential or commercial mortgage loans (“non-agency MBS”).  The principal and interest of our mortgage credit investments are not guaranteed by a GSE or a U.S government agency.  Our MSR related assets represent investments for which the return is based on the economic performance of a pool of specific MSRs. The Company’s SFR investment strategy is to acquire, lease and operate single-family residential homes as rental properties.

We believe we leverage prudently our investment portfolio, as we seek to increase potential returns to our shareholders. We fund our investments primarily through short-term financing arrangements, principally though repurchase agreements. We enter into various hedging transactions to mitigate the interest rate sensitivity of our cost of borrowing and the value of our fixed-rate mortgage investment portfolio.

We are internally managed and do not have an external investment advisor.  

Factors that Affect our Results of Operations and Financial Condition

Our business is materially affected by a variety of industry and economic factors, including:

• conditions in the global financial markets and economic conditions generally;

• the impacts of the coronavirus (“COVID-19”) pandemic;

• changes in interest rates and prepayment rates;

• conditions in the real estate and mortgage markets;

• actions taken by the U.S. government, U.S. Federal Reserve, the U.S. Treasury and foreign central banks;

• changes in laws and regulations and industry practices; and

• other market developments.

Current Market Conditions and Trends

Through most of the third quarter of 2021, equity capital markets continued to strengthen supported by a resilient economic recovery, ongoing accommodative central bank polices and strong corporate earnings results despite headwinds from resurgences in COVID-19 cases in the U.S.  However, market volatility began to rise in late September as many of those positive factors supporting capital markets began to fade with the market focusing on the anticipated impact of supply chain constraints, the looming

29

Congressional fiscal policy battles, a potential financial contagion from an expected default of one of China’s largest property developers and an increased expectation of a near term reversal of the Federal Reserve’s accommodative policies.

At its September 22, 2021 meeting, the Federal Open Market Committee (“FOMC”) stated that it expects to continue to maintain an accommodative monetary policy stance and will keep its target range for the federal funds rate at 0% to 0.25%.  In addition, the FOMC reaffirmed that it will continue with its asset purchase program to help foster smooth market functioning and accommodative financial conditions by continuing to increase its holdings of Treasury securities by at least $80 billion per month and agency MBS by at least $40 billion per month until substantial further progress has been made towards its maximum employment and price stability goals.  However, the FOMC stated that if progress towards these goals continues as expected, that a moderation in the pace of asset purchases may soon be warranted, commonly referred to as “tapering.”  In additional commentary, the FOMC signaled that a gradual tapering process commencing after its scheduled November meeting and concluding around mid-2022 would likely be appropriate assuming the economic recovery remains on track.  Based on federal funds futures, the market is now currently expecting one rate hike in the next twelve months.

The 10-year U.S. Treasury rate increased two basis points during the third quarter to 1.49% as of September 30, 2021.  The U.S. Treasury curve remained relatively unchanged during the third quarter with the spread between the 2-year and 10-year U.S. Treasury rate at 121 basis points as of September 30, 2021.  The spread between the current coupon agency MBS and the 10-year swap rate widened by seven basis points during the third quarter.

Prepayment speeds in the conforming fixed-rate residential mortgage market decreased modestly during the third quarter of 2021 as compared to the prior quarter but remain at elevated levels due to historically low mortgage rates.  Looking forward, market expectations are that historically low interest rates will keep prepayment speeds elevated in the near term. Pay-up premiums on agency MBS, which represent the price premium of agency MBS backed by specified pools over a TBA security, as of September 30, 2021 did not change significantly compared to the prior quarter-end.  

Housing prices have strengthened significantly, as evidenced by the Standard & Poor’s CoreLogic Case-Shiller U.S. National Home Price NSA index reporting an 19.7% annual gain in July 2021, the highest recorded in over 30 years of the index’s data. The strong gains in housing continue to be driven by low mortgage rates and low supply of homes for sale as well as the impact of the COVID-19 pandemic increasing the number of potential home buyers moving from urban apartments to suburban homes.

Recent Regulatory Activity

LIBOR Transition

The ICE Benchmark Administration Limited (“IBA”) is a benchmark administrator that is authorized and regulated by the U.K. Financial Conduct Authority (“FCA”) to administer the publication of LIBOR.  On July 27, 2017, the FCA announced that it intends to stop persuading or compelling banks to submit LIBOR rates after December 31, 2021, which could either cause LIBOR to stop publication immediately or cause LIBOR’s regulator to determine that its quality had degraded to the degree that it is no longer representative of its underlying market.  On March 5, 2021, the FCA announced that all LIBOR tenors relevant to us will cease to be published or will no longer be representative after June 30, 2023. The FCA's announcement coincides with the March 5, 2021 announcement of the IBA indicating that, as a result of not having access to input data necessary to calculate LIBOR tenors relevant to us on a representative basis after June 30, 2023, IBA would have to cease publication of such LIBOR tenors immediately after the last publication on June 30, 2023.

The U.S. Federal Reserve and the Federal Reserve Bank of New York jointly convened the Alternative Reference Rates Committee (“ARRC”), a steering committee comprised of private sector entities, each with an important presence in markets effected by LIBOR, and official-sector entities, including banking and financial sector regulators. The ARCC’s initial objectives were to identify risk-free alternative reference rates for U.S. dollar (“USD”) LIBOR, identify best practices for contract robustness and create an implementation plan. The ARRC identified SOFR, a new index calculated by short-term repurchase agreements backed by U.S. Treasury securities, as the rate that represents the best replacement for USD LIBOR in most USD derivatives and other financial contracts. In April 2018, the Federal Reserve Bank of New York began publishing SOFR rates. The ARRC also published its transition plan with specific steps and timelines designed to encourage the adoption of SOFR.

On April 6, 2021, the state of New York enacted legislation (the “New York LIBOR Legislation”) addressing the phase-out of LIBOR as a benchmark rate in financial instruments governed by New York law.  The New York LIBOR Legislation generally tracks the legislation proposed by the ARRC and provides a statutory remedy for contracts that reference USD LIBOR as a benchmark interest rate but do not include effective fallback provisions in the event USD LIBOR is no longer published or is no longer representative.  Under the New York LIBOR Legislation, if a contract governed by New York law that references USD LIBOR as a benchmark interest rate either does not contain benchmark fallback provisions or contains benchmark fallback provisions that would cause the benchmark rate to fall back to a rate that would continue to be based on USD LIBOR, then the fallback rate would be SOFR plus any applicable spread adjustment and any conforming changes selected or recommended by the Federal Reserve Board, the Federal Reserve Bank of New York or by the ARRC.  The New York LIBOR Legislation also establishes a safe harbor from liability for the selection and use of the recommended benchmark interest rate.  

These announcements mean that any of our LIBOR-based borrowings that extend beyond June 30, 2023 will need to be converted to a replacement rate.  The likely market transition away from LIBOR and towards SOFR is expected to be gradual and complicated.  There are significant differences between LIBOR and SOFR, such as LIBOR being an unsecured lending rate while SOFR is a secured lending rate, and LIBOR reflects term rates at different maturities while SOFR is an overnight rate. These and other differences create the potential for basis risk between the two rates. The impact of any basis risk between LIBOR and SOFR may negatively affect our operating results. Any of these alternative methods may result in interest rates that are either higher or lower than if LIBOR were available in its current form, which could have a material adverse effect on our results. Although SOFR is the ARRC's recommended replacement rate, it is also possible that lenders may instead choose alternative replacement rates that may differ from LIBOR in ways similar to SOFR or in other ways that would result in higher interest costs for us.  It is not yet possible to predict the magnitude of LIBOR's end on our borrowing costs given the remaining uncertainty about which rates will replace LIBOR.

We are party to various financial instruments which include LIBOR as a reference rate that mature or expire after June 30, 2023. As of September 30, 2021, these financial instruments include interest rate swap agreements and unsecured notes and preferred stock issued by the Company.

As of September 30, 2021, we had $115 million notional amount of interest rate swaps outstanding that expire after June 30, 2023 in which we make semiannual interest payments based upon a fixed interest rate and receive quarterly interest payments based upon the prevailing three-month LIBOR on the date of reset. The interest rate swap agreements are centrally cleared by the Chicago Mercantile Exchange (“CME”) which acts as the calculation agent with the terms and conditions of each interest rates swap agreement defined in the CME Rulebook and supplemented by the rules published by the International Swaps and Derivative Association, Inc. (“ISDA”). The fallback terms of interest rate swap agreements that have LIBOR as a reference rate were not originally designed to cover a permanent discontinuation of LIBOR. On October 23, 2020, ISDA amended its rules to provide LIBOR fallback protocols and provisions for bilateral interest rate swap agreements, including defining the LIBOR cessation triggering events and robust fallback provisions.  Under the fallback provisions, the existing contractual rate based on LIBOR rate would fall back to a rate based on SOFR adjusted for the difference in tenor plus a spread adjustment for the historical differences between the two rates.  On January

32

25, 2021, the CME amended its Rulebook to incorporate ISDA’s LIBOR fallback provisions for both new and legacy centrally cleared interest rate swap agreements.

As of September 30, 2021, we had $15.0 million of junior subordinated debt outstanding that require quarterly interest payments at three-month LIBOR plus a spread of 2.25% to 3.00% and matures between 2033 and 2035. Under the terms of the indenture agreement for the notes, if the publication of LIBOR is not available, the current fallback is for the independent calculation agent to obtain quotations for what LIBOR should be from major banks in the interbank market. If the calculation agent is unable to obtain such quotations, then the LIBOR in effect for future interest payments would be LIBOR in effect for the immediately preceding interest payment period.  The indenture governing the junior subordinated notes are governed by New York law and would likely be subject to the fallback rate provisions of the New York LIBOR Legislation.  

As of September 30, 2021, we had 1,117,034 shares of 8.250% Series C Fixed-to-Floating Rate Cumulative Redeemable Preferred Stock (“Series C Preferred Stock”) outstanding with a liquidation preference of $27.9 million. The Series C Preferred Stock is entitled to receive a cumulative cash dividend (i) from and including the original issue to, but excluding, March 30, 2024 at a fixed rate of 8.250% per annum of the $25.00 per share liquidation preference, and (ii) from and including March 30, 2024, at a floating rate equal to three-month LIBOR plus a spread of 5.664% per annum of the $25.00 liquidation preference. Under the terms of our Articles of Incorporation, if the publication of LIBOR is not available, the current fallback is for the Company to obtain quotations for what LIBOR should be from major banks in the interbank market. If we are unable to obtain such quotations, we are required to appoint an independent calculation agent, which will determine LIBOR based on sources it deems reasonable in its sole discretion. If the calculation agent is unable or unwilling to determine LIBOR, then the LIBOR in effect for future dividend payments would be LIBOR in effect for the immediately preceding dividend payment period. Notwithstanding the preceding section of this paragraph, if we determine that LIBOR has been discontinued, we will appoint an independent calculation agent to determine whether there is an industry accepted substitute or successor base rate to three-month LIBOR. If the calculation agent determines that there is an industry accepted substitute or successor base rate, the calculation agent shall use such substitute or successor base rate. If the calculation agent determines that there is not an accepted substitute or successor base rate, then the calculation agent will follow the original fallback language.

At this time, it is not possible to predict the effect of any such changes, any establishment of alternative reference rates or any other reforms to LIBOR that may be implemented in the U.K. or elsewhere. While we expect LIBOR to be available in substantially its current form until the end of 2021, and likely based on IBA's announced consultation through June 2023, if sufficient banks decline to make submissions to IBA, it is possible that LIBOR will become unavailable prior to that point. Uncertainty as to the nature of such potential changes, alternative reference rates or other reforms may adversely affect the market for, or value of, any securities, loans, derivatives and other financial obligations on which the interest or dividend is determined by reference to LIBOR, which could negatively impact our overall financial condition or results of operations. More generally, any of the above changes or any other consequential changes to LIBOR or any other “benchmark” as a result of international, national or other proposals for reform or other initiatives or investigations, or any further uncertainty in relation to the timing and manner of implementation of such changes, could have a material adverse effect on the value of and return on any securities based on or linked to a “benchmark.”

COVID-19 Stimulus

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into legislation that authorizes more than $2 trillion in economic relief to individuals, businesses and government organizations due to the economic and health impacts of the COVID-19 pandemic.  Among its many provisions, the CARES Act instituted a foreclosure moratorium and borrower right to request forbearance on any federally-backed residential mortgage, including mortgage loans in agency MBS.   On July 30, 2021, the Federal Housing Finance Agency (“FHFA”) announced that Fannie Mae and Freddie Mac would not be extending the current foreclosure moratorium date of July 30, 2021; however, the FHFA extended the eviction moratorium until September 30, 2021 on single-family properties that Fannie Mae or Freddie Mac acquired through foreclosure. In addition, under the CARES Act, borrowers of federally-backed residential mortgages may request forbearance if the borrower has experienced financial hardship as a result of the COVID-19 pandemic.  If forbearance is requested by the borrower, the loan servicer is required to grant forbearance for up to 180 days that can be extended for an additional 180 days at the borrower’s request.  During the forbearance period, the servicer cannot charge or collect any fees, penalties, or interest beyond what could be charged if the borrower made all payments timely.  On June 25, 2021, the Federal Housing Authority (“FHA”) further extended the foreclosure moratorium to July 31, 2021 for all federally-backed residential mortgages. The FHA also provided an additional three-month forbearance extension for borrowers who previously received forbearance from their servicer between July 1, 2020 and September 30, 2020, and also extended the time period for borrowers to start new six-month forbearance plans to September 30, 2021. On June 24, 2021, the FHFA further announced that Fannie Mae and Freddie Mac extended their foreclosure moratoriums until July 31, 2021.  On July 30, 2021, the FHA once again further extended its foreclosure moratorium to September 30, 2021.  

33

As a response to COVID-19, many state and local jurisdictions have implemented eviction moratoriums with varying expiration periods. On September 4, 2020, the Centers for Disease Control and Prevention (“CDC”) issued a federal eviction moratorium that temporarily halted residential evictions of qualifying tenants for nonpayment of rent during the period from September 4, 2020 to December 31, 2020.  On August 3, 2021, the CDC issued an extension of the eviction moratorium through October 3, 2021 in counties experiencing substantial and high levels of community transmission levels of COVID-19; however, on August 26, 2021, the U.S. Supreme Court issued a decision immediately ending the CDC eviction moratorium, immediately allowing for evictions to resume.

We expect vigorous debate and discussion in a number of areas, including residential housing and mortgage reform, fiscal policy, monetary policy and healthcare, to continue over the next few years; however, we cannot be certain if or when any specific proposal or policy might be announced, emerge from committee or be approved by Congress, and if so, what the effects on us may be.

The annualized prepayment rate for our agency MBS was 8.62% for the three months ended September 30, 2021. As of September 30, 2021, our agency MBS was comprised of securities specifically selected for their relatively lower propensity for

34

prepayment, which includes approximately 60% in specified pools of low balance loans, approximately 24% in specified pools of loans originated in certain geographical areas and approximately 16% in specified pools of new production serviced by banks. Weighted average pay-up premiums on our agency MBS portfolio, which represent the estimated price premium of agency MBS backed by specified pools over a TBA agency MBS, were approximately one-half of a percentage point as of September 30, 2021.

Our agency MBS portfolio also includes net long TBA positions, which are primarily the result of executing sequential series of “dollar roll” transactions that are settled on a net basis. In accordance with GAAP, we account for our net long TBA positions as derivative instruments. Information about our net long TBA positions as of September 30, 2021 is as follows (dollars in thousands):

MSR Financing Receivables

As of September 30, 2021, we had $112.8 million of MSR financing receivable investments at fair value.  We are party to agreements with a licensed, GSE approved residential mortgage loan servicer that enable us to garner the economic return of an investment in an MSR purchased by the mortgage servicing counterparty.  The arrangement allows us to participate in the economic benefits of investing in an MSR without holding the requisite licenses to purchase or hold MSRs directly.  The transactions are accounted for as a financing receivable in our consolidated financial statements.  The following tables present further information about our MSR financing receivable investments as of September 30, 2021 (dollars in thousands):

Amortized Cost Basis (1)		Unrealized Gain		Fair Value

Economic Hedging Instruments

We attempt to hedge a portion of our exposure to interest rate fluctuations associated with our agency MBS primarily through the use of interest rate hedging instruments. Specifically, these interest rate hedging instruments are intended to economically hedge changes, attributable to changes in benchmark interest rates, in agency MBS fair values and future interest cash flows on our short-term financing arrangements. As of September 30, 2021, the interest rate hedging instruments primarily used by us were centrally cleared interest rate swap agreements.  

Our LIBOR-based interest rate swap agreements represent agreements to make semiannual interest payments based upon a fixed interest rate and receive quarterly variable interest payments based upon the prevailing three-month LIBOR as of the preceding reset date.  Our SOFR-based interest rate swap agreements represent agreements to make annual interest payments based upon a fixed interest rate and receive annual variable interest payments based upon the daily SOFR over the preceding annual period.  Information about our outstanding interest rate swap agreements in effect as of September 30, 2021 is as follows (dollars in thousands):

			Weighted-average:
	Notional Amount		Fixed Pay Rate			Variable Receive Rate			Net Receive (Pay) Rate			Remaining Life (Years)
Years to maturity:
Less than 3 years	$	100,000		0.11	%		0.04	%		(0.07	)%		2.1
3 to less than 10 years		115,000		1.09	%		0.10	%		(0.99	)%		9.3
Total / weighted-average	$	215,000		0.64	%		0.07	%		(0.57	)%		6.0

In addition to interest rate swap agreements, we may also use exchange-traded U.S. Treasury note futures that are either long or short positions that mature on a quarterly basis. Upon the maturity date of these futures contracts, we have the option to either net settle each contract in cash in an amount equal to the difference between the current fair value of the underlying U.S. Treasury note and the contractual sale price inherent to the futures contract, or to physically settle the contract by purchasing or delivering the underlying U.S. Treasury note. As of September 30, 2021, we had no outstanding U.S. Treasury note futures.

Mortgage Credit Investment Portfolio

As of September 30, 2021, our mortgage credit investment portfolio was primarily comprised of a $29.8 million commercial mortgage loan secured by a first lien position in healthcare facilities and $37.9 million in non-agency MBS investments collateralized by pools of residential mortgage loans, business purpose residential mortgage loans and small balance commercial mortgage loans, including a $12.4 million net investment in a consolidated variable interest entity (“VIE”).  The following table presents further information about our mortgage credit investments as of September 30, 2021 (dollars in thousands):

Results of Operations

Net Interest Income

Net interest income determined in accordance with GAAP primarily represents the interest income recognized from our specified agency MBS, mortgage credit investments and MSR financing receivables (including the amortization of purchase premiums and accretion of purchase discounts), net of the interest expense incurred from repurchase agreement financing arrangements or other short- and long-term borrowing transactions. 

Net interest income determined in accordance with GAAP does not include TBA agency MBS dollar roll income, which we believe represents the economic equivalent of net interest income generated from our investments in non-specified fixed-rate agency MBS, nor does it include the net interest income or expense of our interest rate swap agreements, which are not designated as hedging instruments for financial reporting purposes. In our consolidated statements of comprehensive income prepared in accordance with GAAP, TBA agency MBS dollar roll income and the net interest income or expense from our interest rate swap agreements are reported as a component of the overall periodic change in the fair value of derivative instruments within the line item “gain (loss) from derivative instruments, net” of the “investment gain (loss), net” section.

Investment Gain (Loss), Net

“Investment gain (loss), net” primarily consists of periodic changes in the fair value (whether realized or unrealized) of the Company’s mortgage investments and periodic changes in the fair value (whether realized or unrealized) of derivative instruments.

General and Administrative Expenses

“Compensation and benefits expense” includes base salaries, annual cash incentive compensation, and non-cash stock-based compensation. Annual cash incentive compensation is based on meeting estimated annual performance measures and discretionary components. Non-cash stock-based compensation includes expenses associated with stock-based awards granted to employees, including the Company’s performance share units to named executive officers that are earned only upon the attainment of Company performance measures over the relevant measurement period.

“Other general and administrative expenses” primarily consists of the following:

• professional services expenses, including accounting, legal, and consulting fees;

• insurance expenses, including liability and property insurance;

• occupancy and equipment expense, including rental costs for our facilities, and depreciation and amortization of equipment and software;

37

• fees and commissions related to transactions in interest rate derivative instruments;

• Board of Director fees; and

• other operating expenses, including information technology expenses, business development costs, public company reporting expenses, proxy solicitation expenses, corporate registration fees, local license taxes, office supplies and other miscellaneous expenses.

Economic Net Interest Income

Economic net interest income, a non-GAAP financial measure, represents the interest income earned net of the interest expense incurred from all of our interest bearing financial instruments as well as the agency MBS which underlie, and are implicitly financed through, our TBA dollar roll transactions. Economic net interest income is comprised of the following: (i) net interest income determined in accordance with GAAP, (ii) TBA agency MBS “dollar roll” income and (iii) net interest income earned or expense incurred from interest rate swap agreements. We believe that economic net interest income assists investors in understanding and evaluating the financial performance of the Company’s long-term-focused, net interest spread-based investment strategy, prior to the deduction of general and administrative expenses. For a full description of each of the three aforementioned components of economic net interest income, see “Non-GAAP Core Operating Income” below.

Below is a reconciliation of economic net interest income, a non-GAAP financial measure, to net interest income determined in accordance with GAAP (dollars in thousands):

Investment Gain (Loss), Net

As prevailing longer-term interest rates increase (decrease), the fair value of our investments in fixed-rate agency MBS and TBA commitments generally decreases (increases).  Conversely, the fair value of our interest rate derivative hedging instruments and MSR financing receivables generally increase (decrease) in response to increases (decreases) in prevailing interest rates.  While our interest rate derivative hedging instruments are designed to mitigate the sensitivity of the fair value of our agency MBS portfolio to fluctuations in interest rates, they are not generally designed to mitigate the sensitivity of our net book value to spread risk, which is the risk of an increase of the market spread between the yield on our agency MBS and the benchmark yield on U.S. Treasury securities or interest rate swaps.  Accordingly, irrespective of fluctuations in interest rates, an increase (decrease) in agency MBS spreads will generally result in the underperformance (outperformance) of the values of agency MBS relative to interest rate hedging instruments.

The following table presents information about the gains and losses recognized due to the changes in the fair value of our investments and interest rate hedging instruments for the periods indicated (dollars in thousands):

General and Administrative Expenses

General and administrative expenses decreased by $0.1 million, or 3.3%, from $3.0 million for the three months ended September 30, 2020 to $2.9 million for the three months ended September 30, 2021. General and administrative expenses decreased by $0.8 million, or 8.4%, from $9.5 million for the nine months ended September 30, 2020 to $8.7 million for the nine months ended September 30, 2021. The decrease in general and administrative expenses for the nine months ended September 30, 2021 is primarily due to a decrease in compensation and benefits expense and professional services expenses.

Compensation and benefits expense increased by $0.1 million, or 5.6%, from $1.8 million for the three months ended September 30, 2020 to $1.9 million for the three months ended September 30, 2021. Compensation and benefits expense decreased by $0.4 million, or 7.3%, from $5.5 million for the nine months ended September 30, 2020 to $5.1 million for the nine months ended September 30, 2021. The decrease in compensation and benefits for the nine months ended September 30, 2021 is primarily due to a decrease in management cash incentive compensation.

Other general and administrative expenses decreased by $0.2 million, or 16.7%, from $1.2 million for the three months ended September 30, 2020 to $1.0 million for the three months ended September 30, 2021. Other general and administrative expenses decreased by $0.4 million, or 10.0%, from $4.0 million for the nine months ended September 30, 2020 to $3.6 million for the nine months ended September 30, 2021. The decrease in other general and administrative expenses for the nine months ended September 30, 2021 is primarily due to a decrease in professional services expenses.

Income Tax Provision

Our taxable REIT subsidiaries (“TRSs”) are subject to U.S. federal and state corporate income taxes.  As a result, for the three and nine months ended September 30, 2021, we recognized a provision for income taxes of $0.4 and $0.8 million, respectively, on the pre-tax net income of our TRSs.  As noted in “Non-GAAP Core Operating Income” below, our computation of non-GAAP core operating income includes a provision for income taxes on the core operating income of our TRSs.  TRS core operating income is comprised of net interest income generated by TRSs net of the TRSs’ general and administrative expenses.  In our consolidated financial consolidated statements of comprehensive income prepared in accordance with GAAP, the “income tax provision (benefit)” includes (i) the income tax provision for TRS core operating income and (ii) an income tax provision for (or benefit from) periodic increases (or decreases) in the fair value of the investments of our TRSs, which are recognized in net income as a component of “investment gain (loss) net.”  Below is a reconciliation of the income tax provision for TRS core operating income, a non-GAAP financial measure, to the income tax provision determined in accordance with GAAP (dollars in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Income tax provision for TRS core operating income	$	85	$	—	$	157	$	—
Income tax provision for TRS investment gains, net		351		—		601		—
GAAP income tax provision	$	436	$	—	$	758	$	—

Non-GAAP Core Operating Income

In addition to the results of operations determined in accordance with GAAP, we also report “non-GAAP core operating income.” We define core operating income as “economic net interest income” and “single-family residential property operating profit” less “core general and administrative expenses,” “income tax provision for TRS core operating income” and preferred stock dividends.

Economic Net Interest Income

Economic net interest income, a non-GAAP financial measure, represents the interest income earned net of the interest expense incurred from all of our interest-bearing financial instruments as well as the agency MBS which underlie, and are implicitly financed through, our TBA dollar roll transactions. Economic net interest income is comprised of the following: (i) net interest income determined in accordance with GAAP, (ii) TBA agency MBS “dollar roll” income, and (iii) net interest income earned or expense incurred from interest rate swap agreements.

We believe that economic net interest income assists investors in understanding and evaluating the financial performance of our long-term-focused, net interest spread-based investment strategy, prior to the deduction of core general and administrative expenses.

• Net interest income determined in accordance with GAAP.  Net interest income determined in accordance with GAAP primarily represents the interest income recognized from our investments in specified agency MBS, mortgage credit investments and MSR financing receivables (including the amortization of purchase premiums and accretion of purchase discounts), net of the interest expense incurred from repurchase agreement financing arrangements or other short- and long-term borrowing transactions income.

• TBA agency MBS dollar roll income.  Dollar roll income represents the economic equivalent of net interest income (implied interest income net of financing costs) generated from our investments in non-specified fixed-rate agency MBS, executed through sequential series of forward-settling purchase and sale transactions that are settled on a net basis (known as “dollar roll” transactions). Dollar roll income is generated as a result of delaying, or “rolling,” the settlement of a forward-settling purchase of a TBA agency MBS by entering into an offsetting “spot” sale with the same counterparty prior to the settlement date, net settling the “paired-off” positions in cash, and contemporaneously entering another forward-settling purchase with the same counterparty of a TBA agency MBS of the same essential characteristics for a later settlement date at a price discount relative to the spot sale. The price discount of the forward-settling purchase relative to the contemporaneously executed spot sale reflects compensation for the interest income (inclusive of expected prepayments) that, at the time of sale, is expected to be foregone as a result of relinquishing beneficial ownership of the MBS from the settlement date of the spot sale until the settlement date of the forward purchase, net of implied repurchase financing costs. We calculate dollar roll income as the excess of the spot sale price over the forward-settling purchase price, and recognize this amount ratably over the period beginning on the settlement date of the sale and ending on the settlement date of the forward purchase. In our consolidated statements of comprehensive income prepared in accordance with GAAP, TBA agency MBS dollar roll income is reported as a component of the overall periodic change in the fair value of TBA forward commitments within the line item “gain (loss) from derivative instruments, net” of the “investment gain (loss), net” section.

From time to time, we may enter into forward-settling TBA agency MBS sale commitments (known as a “net short” TBA position) as a means of economically hedging a portion of the interest rate sensitivity of our agency MBS investment portfolio.  When we delay (or “roll”) the settlement of a net short TBA position, the price discount of the forward-settling sale relative to the contemporaneously executed spot purchase results in an implied net interest expense (i.e., “dollar roll expense”).  In our presentation of non-GAAP core operating income, we present TBA dollar roll income net of any implied net interest expense that resulted from rolling the settlement of net short TBA positions.

• Net interest income earned or expense incurred from interest rate swap agreements. We utilize interest rate swap agreements to economically hedge a portion of our exposure to variability in future interest cash flows, attributable to changes in benchmark interest rates, associated with future roll-overs of our short-term financing arrangements. Accordingly, the net interest income earned or expense incurred (commonly referred to as “net interest carry”) from our interest rate swap agreements in combination with interest expense recognized in accordance with GAAP represents our effective “economic interest expense.” In our consolidated statements of comprehensive income prepared in accordance with GAAP, the net interest income earned or expense incurred from interest rate swap agreements is reported as a component of the overall periodic change in the fair value of derivative instruments within the line item “gain (loss) from derivative instruments, net” of the “investment gain (loss), net” section.

Single-family Residential Property Profit

Single-family residential property profit represents the operating profit of the Company’s single-family residential properties determined in accordance with GAAP plus the depreciation and amortization of the single-family residential properties.  

Core General and Administrative Expenses

Core general and administrative expenses are non-interest expenses reported within the line item “total general and administrative expenses” of the consolidated statements of comprehensive income less stock-based compensation expense.  

Income Tax Provision for TRS Core Operating Income

Our TRSs are subject to U.S. federal and state corporate income taxes.  Our computation of core operating income includes a provision for income taxes on the core operating income of our TRSs.  The core operating income of our TRSs is comprised of net interest income generated by our TRSs net of our TRSs’ general and administrative expenses.  In our consolidated statements of comprehensive income prepared in accordance with GAAP, the “income tax provision (benefit)” includes (i) the income tax provision for TRS core operating income and (ii) an income tax provision for (or benefit from) periodic increases (or decreases) in the fair value of the investments of our TRSs, which are recognized in net income as a component of “investment gain (loss) net.”

Non-GAAP core operating income	$	1,900		$	973		$	5,157		$	7,624

Non-GAAP core operating income is used by management to evaluate the financial performance of our long-term-focused, net interest spread-based investment strategy and core business activities over periods of time as well as assist with the determination of the appropriate level of periodic dividends to common stockholders. In addition, we believe that non-GAAP core operating income assists investors in understanding and evaluating the financial performance of our long-term-focused, net interest spread-based investment strategy and core business activities over periods of time as well as its earnings capacity.

Periodic fair value gains and losses recognized with respect to our mortgage investments and economic hedging instruments, which are reported in line item “total investment gain (loss), net” of our consolidated statements of comprehensive income, are excluded from the computation of non-GAAP core operating income as such gains on losses are not reflective of the economic interest income earned or interest expense incurred from our interest-bearing financial assets and liabilities during the indicated reporting period.  Because our long-term-focused investment strategy for our mortgage investment portfolio is to generate a net interest spread on the leveraged assets while prudently hedging periodic changes in the fair value of those assets attributable to changes in benchmark interest rates, we generally expect the fluctuations in the fair value of our mortgage investments and economic hedging instruments to largely offset one another over time.

A limitation of utilizing this non-GAAP financial measure is that the effect of accounting for “non-core” events or transactions in accordance with GAAP does, in fact, reflect the financial results of our business and these effects should not be ignored when evaluating and analyzing our financial results. For example, the economic cost or benefit of hedging instruments other than interest

44

rate swap agreements, such as U.S. Treasury note futures or options, do not affect the computation of non-GAAP core operating income.  In addition, our calculation of non-GAAP core operating income may not be comparable to other similarly titled measures of other companies.  Therefore, we believe that non-GAAP core operating income should be considered as a supplement to, and in conjunction with, net income and comprehensive income determined in accordance with GAAP. Furthermore, there may be differences between non-GAAP core operating income and taxable income determined in accordance with the Internal Revenue Code.  As a REIT, we are required to distribute at least 90% of our REIT taxable income (subject to certain adjustments) to qualify as a REIT and all of our taxable income in order to not be subject to any U.S. federal or state corporate income taxes. Accordingly, non-GAAP core operating income may not equal our distribution requirements as a REIT.

Liquidity and Capital Resources

Liquidity is a measurement of our ability to meet potential cash requirements including ongoing commitments to repay borrowings, fund investments, meet margin calls on our short-term borrowings and hedging instruments, and for other general business purposes. Our primary sources of funds for liquidity consist of existing cash balances, short-term borrowings (for example, repurchase agreements), principal and interest payments from our mortgage investments, and proceeds from sales of mortgage investments. Other sources of liquidity include proceeds from the offering of common stock, preferred stock, debt securities, or other securities registered pursuant to our effective shelf registration statement filed with the Securities and Exchange Commission (“SEC”).

Liquidity, or ready access to funds, is essential to our business. Perceived liquidity issues may affect our counterparties’ willingness to engage in transactions with us. Our liquidity could be impaired due to circumstances that we may be unable to control, such as a general market disruption or an operational problem that affects us or third parties. Further, our ability to sell assets may be impaired if other market participants are seeking to sell similar assets at the same time. If we cannot obtain funding from third parties our results of operations could be negatively impacted.

As of September 30, 2021, our debt-to-equity leverage ratio was 2.9 to 1 measured as the ratio of the sum of our total debt to our stockholders’ equity as reported on our consolidated balance sheet.  In evaluating our liquidity and leverage ratios, we also monitor our “at risk” leverage ratio.  Our “at risk” leverage ratio is measured as the ratio of the sum of our repurchase agreement financing, net payable or receivable for unsettled securities, net contractual forward price of our TBA commitments, leverage within our MSR financing receivable less our cash and cash equivalents compared to our investable capital.  Our investable capital is calculated as the sum of our stockholders’ equity and long-term unsecured debt.  As of September 30, 2021, our “at risk” leverage ratio was 1.8 to 1.  

As of September 30, 2021, the Company’s liquid assets totaled $100.3 million consisting of cash and cash equivalents of $21.2 million and unencumbered agency MBS of $79.1 million at fair value. Cash equivalents consist primarily of money market funds invested in debt obligations of the U.S. government.

Due to the ongoing economic impact of the COVID-19 pandemic on the financial markets, we may experience increased difficulty in our financing operations. During the period immediately after the beginning of the COVID-19 pandemic, mortgage REITs experienced severe disruptions in financing operations (including the cost, attractiveness and availability of financing), in particular the ability to utilize repurchase financing and the margin requirements related to such financing.  While funding conditions have improved significantly since mid-2020, if the ongoing economic impact of COVID-19 were to, again, cause severe disruptions in financing operations, we could experience an unwillingness or inability of our potential lenders to provide us with, or renew, financing, increased margin calls, and/or additional capital requirements. These conditions could force us to sell our assets at inopportune times or otherwise cause us to potentially revise our strategic business initiatives, which could adversely affect our business.

We are continuing to monitor the rapid developments around COVID-19 and the related impacts to our business. In response to the economic uncertainty that has unfolded as a result of COVID-19, we took steps to lower our repurchase agreement leverage and maintain what we believe to be a sufficient liquidity position.

Sources of Funding

We believe that our existing cash balances, net investments in mortgage investments, cash flows from operations, borrowing capacity, and other sources of liquidity will be sufficient to meet our cash requirements for at least the next twelve months. We may, however, seek debt or equity financings, in public or private transactions, to provide capital for corporate purposes and/or strategic business opportunities, including possible acquisitions, joint ventures, alliances or other business arrangements which could require substantial capital outlays. Our policy is to evaluate strategic business opportunities, including acquisitions and divestitures, as they arise. There can be no assurance that we will be able to generate sufficient funds from future operations, or raise sufficient debt or equity on acceptable terms, to take advantage of investment opportunities that become available. Should our needs ever exceed these

45

sources of liquidity, we believe that most of our investments could be sold, in most circumstances, to provide cash. However, we may be required to sell our assets in such instances at depressed prices.

Cash Flows

As of September 30, 2021, our cash totaled $24.7 million, which included cash and cash equivalents of $21.2 million, restricted cash of $0.2 million, and restricted cash of a consolidated VIE of $3.3 million, representing a net decrease of $15.3 million from $40.0 million as of December 31, 2020. Cash provided by operating activities of $4.9 million during the nine months ended September 30, 2021 was attributable primarily to net interest income less our general and administrative expenses. Cash provided by investing activities of $164.7 million during the nine months ended September 30, 2021 was primarily generated by sales of agency MBS and mortgage credit securities, receipt of principal payments from agency MBS and principal receipts on loans and mortgage loans of a consolidated VIE, partially offset by purchases of new agency MBS, mortgage credit securities, a mortgage loan, MSR financing receivables, and single-family residential real estate as well as net payments for settlements and deposits for margin on our interest rate derivative instruments. Cash used in financing activities of $184.9 million during the nine months ended September 30, 2021 was primarily from repayments of repurchase agreements, net repayments of secured debt of a consolidated VIE, redemption of long-term unsecured debt, dividend payments to stockholders and from repurchases of our common stock, partially offset by proceeds from issuance of long-term unsecured debt.

Debt Capital

Long-Term Unsecured Debt

As of September 30, 2021, we had $85.9 million of total long-term unsecured debt, net of unamortized debt issuance costs of $1.8 million. Our 6.75% Senior Notes due 2025 with a principal amount of $34.9 million outstanding as of September 30, 2021 accrue and require payment of interest quarterly at an annual rate of 6.75% and mature on March 15, 2025. Our 6.00% Senior Notes due 2026 with a principal amount of $37.8 million outstanding as of September 30, 2021 accrue and require payment of interest quarterly at an annual rate of 6.00% and mature on August 1, 2026. Our trust preferred debt with a principal amount of $15.0 million outstanding as of September 30, 2021 accrue and require the payment of interest quarterly at three-month LIBOR plus 2.25% to 3.00% and mature between 2033 and 2035. Our Senior Notes due 2025 and trust preferred debt may be redeemed in whole or part at any time and from time to time at our option at a redemption price equal to the principal amount plus accrued and unpaid interest. Our Senior Notes due 2026 may be redeemed in whole or in part at any time and from time to time at the Company’s option on or after August 1, 2023 at a redemption price equal to the principal amount plus accrued and unpaid interest.  

Repurchase Agreements

We have short-term financing facilities that are structured as repurchase agreements with various financial institutions to fund our mortgage investments. We have obtained, and believe we will be able to continue to obtain, short-term financing in amounts and at interest rates consistent with our financing objectives. Funding for mortgage investments through repurchase agreements continues to be available to us at rates we consider to be attractive from multiple counterparties.

Our repurchase agreements to finance our acquisition of MBS include provisions contained in the standard master repurchase agreement as published by the Securities Industry and Financial Markets Association (“SIFMA”) and may be amended and supplemented in accordance with industry standards for repurchase facilities.  Certain of our repurchase agreements include financial covenants, with which the failure to comply would constitute an event of default. Similarly, each repurchase agreement includes events of insolvency and events of default on other indebtedness as similar financial covenants. As provided in the standard master repurchase agreement as typically amended, upon the occurrence of an event of default or termination, the applicable counterparty has the option to terminate all repurchase transactions under such counterparty’s repurchase agreement and to demand immediate payment of any amount due from us.

Our repurchase agreement to finance our acquisition of mortgage loans is subject to a master repurchase agreement between a wholly-owned subsidiary of the Company, for which we provide a full guarantee of performance, and a third party lender.  The agreement contains financial covenants including our maintenance of a minimum level of net worth, liquidity and profitability, with which the failure to comply would constitute an event of default. Similarly, the agreement includes events of insolvency and events of default on other indebtedness as similar financial covenants. Upon the occurrence of an event of default or termination, the counterparty has the option to terminate all other indebtedness arrangements with us and to demand immediate payment of any amount due from us.

Under our repurchase agreements, we may be required to pledge additional assets to our repurchase agreement counterparties in the event the estimated fair value of the existing pledged collateral under such agreements declines and such lenders demand additional collateral (commonly referred to as a “margin call”), which may take the form of additional securities or cash. Margin calls

46

on repurchase agreements collateralized by our mortgage investments primarily result from events such as declines in the value of the underlying mortgage collateral caused by factors such as rising interest rates, higher prepayments or higher actual or expected credit losses. Our repurchase agreements generally provide that valuations for mortgage investments securing our repurchase agreements are to be obtained from a generally recognized source agreed to by both parties.  However, in certain circumstances and under certain of our repurchase agreements, our lenders have the sole discretion to determine the value of the mortgage investments securing our repurchase agreements. In such instances, our lenders are required to act in good faith in making determinations of value. Our repurchase agreements generally provide that in the event of a margin call, we must provide cash or additional securities on the same business day that the margin call is made if the lender provides us notice prior to the margin notice deadline on such day.  

To date, we have not had any margin calls on our repurchase agreements that we were not able to satisfy with either cash or additional pledged collateral. However, should we encounter increases in interest rates or prepayments, margin calls on our repurchase agreements could result in a material adverse change in our liquidity position.

Our repurchase agreement counterparties apply a “haircut” to the value of the pledged collateral, which means the collateral is valued, for the purposes of the repurchase agreement transaction, at less than fair value.  Upon the renewal of a repurchase agreement financing at maturity, a lender could increase the “haircut” percentage applied to the value of the pledged collateral, thus reducing our liquidity.

Our repurchase agreements generally mature within 30 to 60 days, but may have maturities as short as one day and as long as one year. In the event that market conditions are such that we are unable to continue to obtain repurchase agreement financing for our mortgage investments in amounts and at interest rates consistent with our financing objectives, we may liquidate such investments and may incur significant losses on any such sales of mortgage investments.

The following table provides information regarding our outstanding repurchase agreement borrowings as of the date and period indicated (dollars in thousands):

<sup>(1)</sup> Net amount represents the value of collateral in excess of corresponding repurchase obligation. The amount of collateral at-risk is limited to the outstanding repurchase obligation and not the entire collateral balance.

To limit our exposure to counterparty risk, we diversify our repurchase agreement funding across multiple counterparties and by counterparty region. As of September 30, 2021, we had outstanding repurchase agreement balances with eight counterparties and have master repurchase agreements in place with a total of 17 counterparties located throughout North America, Europe and Asia. As of September 30, 2021, no more than 4.0% of our stockholders’ equity was at risk with any one counterparty, with the top five counterparties representing approximately 12.5% of our stockholders’ equity. The table below includes a summary of our repurchase agreement funding by number of counterparties and counterparty region as of September 30, 2021:

47

	Number of		Percentage of Repurchase

Long-term Secured Debt

McLean SFR Investment, LLC (“McLean SFR”), a wholly-owned subsidiary of Arlington Asset, is party to a loan agreement with a third-party lender to fund McLean SFR’s purchases of SFR properties.  Under the terms of the loan agreement, loan advances may be drawn up to 74% of the fair value of eligible SFR properties up to a maximum loan amount of $150 million.  Advances under the loan agreement may be drawn during the advance period, which ends on the earlier of the date the outstanding principal balance equals the maximum loan amount or March 28, 2023.  The outstanding principal balance is due on October 9, 2026 and advances under the loan agreement bear interest at a fixed rate of 2.76%. As of September 30, 2021, there were no advances outstanding under the loan agreement.

Through September 28, 2024, the outstanding principal balance may be prepaid in an amount equal to the excess of (i) the sum of the present value of all remaining scheduled payments of principal and interest on the principal amount of the loan being prepaid discounted using a U.S. Treasury rate over (ii) the outstanding principal balance of the loan.  Subsequent to September 28, 2024, the outstanding principal balance may be prepaid in an amount equal to the outstanding principal balance plus accrued interest.

The loan is secured by a first priority interest in all the assets of McLean SFR and a first priority pledge of the equity interest of McLean SFR. If the outstanding principal balance of the loan is greater than 74% of the fair value of the eligible collateral, McLean SFR is required to either pledge additional collateral or prepay the loan in an amount so that the outstanding principal balance does not exceed 74% of the fair value of the eligible collateral.  Under the terms of the loan agreement, if McLean SFR does not maintain a minimum debt service coverage ratio for a specified time period, then all available cash of McLean SFR will be held as additional collateral for the loan amount until the minimum debt service coverage ratio is met.  The obligations under the loan agreement may become recourse to Arlington Asset upon the occurrence of certain enumerated acts committed by McLean SFR or Arlington Asset.  The loan agreement contains a minimum net worth financial covenant of Arlington Asset.

Derivative Instruments

In the normal course of our operations, we are a party to financial instruments that are accounted for as derivative financial instruments including (i) interest rate hedging instruments such as interest rate swaps, U.S. Treasury note futures, put and call options on U.S. Treasury note futures, Eurodollar futures, interest rate swap futures and options on agency MBS, and (ii) derivative instruments that economically serve as investments such as TBA purchase and sale commitments.

Interest Rate Hedging Instruments

We exchange cash variation margin with the counterparties to our interest rate hedging instruments at least on a daily basis based upon daily changes in fair value as measured by the central clearinghouse through which those derivatives are cleared. In addition, the central clearinghouse requires market participants to deposit and maintain an “initial margin” amount which is determined by the clearinghouse and is generally intended to be set at a level sufficient to protect the clearinghouse from the maximum estimated single-day price movement in that market participant’s contracts. However, the futures commission merchants (“FCMs”) through which we conduct trading of our cleared and exchanged-traded hedging instruments may require incremental initial margin in excess of the clearinghouse’s requirement. The clearing exchanges have the sole discretion to determine the value of our hedging instruments for the purpose of setting initial and variation margin requirements or otherwise.  In the event of a margin call, we must generally provide additional collateral on the same business day. To date, we have not had any margin calls on our hedging agreements that we were not able to satisfy. However, if we encounter significant decreases in long-term interest rates, margin calls on our hedging agreements could result in a material adverse change in our liquidity position.

As of September 30, 2021, we had outstanding interest rate swaps with the following aggregate notional amount and corresponding initial margin held in collateral deposit with the custodian (dollars in thousands):

	September 30, 2021
	Notional		Collateral
	Amount		Deposit
Interest rate swaps	$	215,000	$	5,384

48

The FCMs through which we conduct trading of our hedging instruments may limit their exposure to us (due to an inherent one business day lag in the variation margin exchange process) by applying a maximum “ceiling” on their level of risk, either overall and/or by instrument type.  The FCMs generally use the amount of initial margin that we have posted with them as a measure of their level of risk exposure to us.  We currently have FCM relationships with three large financial institutions.  To date, among our three FCM arrangements, we have had sufficient excess capacity above and beyond what we believe to be a sufficient and appropriate hedge position.  However, if our FCMs substantially lowered their risk exposure thresholds, we could experience a material adverse change in our liquidity position and our ability to hedge appropriately.

TBA Dollar Roll Transactions

TBA dollar roll transactions represent a form of off-balance sheet financing accounted for as derivative instruments.  In a TBA dollar roll transaction, we do not intend to take physical delivery of the underlying agency MBS and will generally enter into an offsetting position and net settle the paired-off positions in cash.  However, under certain market conditions, it may be uneconomical for us to roll our TBA contracts into future months and we may need to take or make physical delivery of the underlying securities. If we were required to take physical delivery to settle a long TBA contract, we would have to fund our total purchase commitment with cash or other financing sources and our liquidity position could be negatively impacted.

Margin Requirements for Agency MBS Purchase and Sale Commitments

Our commitments to purchase and sell agency MBS, including TBA commitments, are subject to master securities forward transaction agreements published by SIFMA as well as supplemental terms and conditions with each counterparty.  Under the terms of these agreements, we may be required to pledge collateral to our counterparty in the event the fair value of the agency MBS underlying our purchase and sale commitments change and such counterparty demands collateral through a margin call.  Margin calls on agency MBS commitments are generally caused by factors such as rising interest rates or prepayments.  Our agency MBS commitments provide that valuations for our commitments and any pledged collateral are to be obtained from a generally recognized source agreed to by both parties.  However, in certain circumstances, our counterparties have the sole discretion to determine the value of the agency MBS commitment and any pledged collateral. In such instances, our counterparties are required to act in good faith in making determinations of value.  In the event of a margin call, we must generally provide additional collateral on the same business day.  

MSR Financing Receivable Commitments

We are party to agreements with a licensed, GSE approved residential mortgage loan servicer that enables us to garner the economic return of an investment in an MSR purchased by the mortgage servicing counterparty through an MSR financing transaction.  We have committed to invest a total minimum of $50 million of capital with the counterparty with $25 million of the minimum commitment expiring on December 31, 2023 and $25 million of the minimum commitment expiring on April 1, 2024.  As of September 30, 2021, we have fully funded the total minimum commitment. At any time prior to minimum commitment expiration dates, we have the option to request the mortgage servicing counterparty to sell the related MSR investments and repay us amounts owed to us under the MSR financing transaction less a minimum fee the mortgage servicing counterparty would have earned on the minimum commitment amounts over the remaining original commitment periods.

At our election, the mortgage servicing counterparty could utilize leverage on the MSRs that are subject to our MSR financing receivables to finance the purchase of additional MSRs to increase potential returns to us.  The lender providing the leverage to our mortgage servicing counterparty would have a secured interest in the MSRs pledged under a credit facility between the lender and our mortgage servicing counterparty.  Draws under the credit facility bear interest at three-month LIBOR plus 2.75% with a LIBOR floor of 1.75% with a maturity date of April 29, 2022 with two one-year borrower extension options.  In general, our mortgage servicing counterparty can obtain advances of up to 60% of the fair value of the collateral value. Under our mortgage servicing counterparty’s credit facility, if the fair value of the pledged MSR collateral declines and the lender demands additional collateral from our mortgage servicing counterparty through a margin call, we would be required to provide the mortgage servicing counterparty with additional funds to meet such margin call.  If we were unable to satisfy such margin call, the lender could liquidate the MSR collateral position that are referenced to our MSR financing receivables to satisfy the loan obligation and thereby reducing the value of our MSR financing receivables.  As of September 30, 2021, our mortgage servicing counterparty has drawn $11.5 million of financing under its credit facility collateralized by $120.6 million of MSRs referenced to our MSR financing receivable.

Our mortgage servicing counterparty may also pledge MSRs subject to other similar MSR financing receivable relationships with other third parties as collateral under the same credit facility that have a pledge of the MSRs referenced to our MSR financing receivable.  If such third party to another MSR financing receivable were unable to satisfy a margin call on its referenced pool of MSRs and the value of such MSRs were insufficient to satisfy the corresponding debt obligation to the lender, the lender would have recourse to the MSRs referenced to our MSR financing receivables.  In such case, if the mortgage servicing counterparty to our MSR

49

financing receivables fails to satisfy such third party’s shortfall, the lender could liquidate the MSRs to which our MSR financing receivables are referenced if we did not fund such remaining margin deficiency.  As a result of this cross collateralization of our mortgage servicing counterparty’s credit facility, the value of our MSR financing receivables may be adversely impacted by the inability of our mortgage servicing counterparty’s other contracted parties to meet their margin calls.  

Under the arrangement, we are obligated to provide funds to the mortgage servicing counterparty to fund its advances of delinquent payments on the serviced pool of mortgage loans within the referenced MSR with the mortgage servicing counterparty required to return to us any subsequent servicing advances collected.  At our option, we could instruct the mortgage servicing counterparty to fund any servicing advances with draws under its credit facility, subject to available borrowing capacity, while we would be required to fund such financing costs.

Investment Commitments

We are party to an investment management agreement with a third party to invest up to $50 million of capital in SFR properties.  Under the terms of the investment management agreement, if we were to terminate the commitment, we would have to pay a termination fee equal to a fixed amount less fees paid inception to date.

As of September 30, 2021, we are a party to a participation agreement pursuant to which we have committed to fund up to $30 million of a $130 million revolving credit facility that matures on July 7, 2024.  Under the terms of the participation agreement, we are obligated to fund the last $30 million of advances under the revolving credit facility.  As of September 30, 2021, our unfunded commitment was $30 million.

Equity Capital

Common Equity Distribution Agreements

We are party to separate common equity distribution agreements with equity sales agents JMP Securities LLC, B. Riley FBR, Inc., JonesTrading Institutional Services LLC and Ladenburg Thalmann & Co. Inc. pursuant to which we may offer and sell, from time to time, shares of our Class A common stock.  Pursuant to the common equity distribution agreements, shares of our common stock may be offered and sold through the equity sales agents in transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act of 1933, including sales made directly on the NYSE or sales made to or through a market maker other than on an exchange or, subject to the terms of a written notice from us, in privately negotiated transactions. During the three and nine months ended September 30, 2021, there were no issuances of common stock under the common equity distribution agreements. As of September 30, 2021, we had 11,302,160 shares of Class A common stock available for sale under the common equity distribution agreements.

Common Share Repurchase Program

Our Board of Directors has authorized a share repurchase program pursuant to which we may repurchase shares of Class A common stock (the “Repurchase Program”).

50

Preferred Stock are redeemable at $25.00 per share, plus accumulated and unpaid dividends (whether or not authorized or declared) exclusively at our option commencing on March 30, 2024 or earlier upon the occurrence of a change in control or under circumstances where it is necessary to preserve our qualification as a REIT.  Under certain circumstances upon a change of control, the Series C Preferred Stock is convertible into shares of our common stock.  Dividends will be payable quarterly in arrears on the 30th day of March, June, September and December of each year, when and as declared. We have declared and paid all required quarterly dividends on our Series C Preferred Stock to date.

Preferred Equity Distribution Agreement

We are party to an amended and restated equity distribution agreement with JonesTrading Institutional Services LLC and Ladenburg Thalmann & Co. Inc., pursuant to which we may offer and sell, from time to time, shares of our Series B Preferred Stock. Pursuant to the Series B preferred equity distribution agreement, shares of our Series B Preferred stock may be offered and sold through the preferred equity sales agents in transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act of 1933, including sales made directly on the NYSE or sales made to or through a market maker other than on an exchange or, subject to the terms of a written notice from us, in privately negotiated transactions.

During the three and nine months ended September 30, 2021, we issued 22,719 shares of our Series B preferred stock at a weighted average public offering price of $24.99 per share for proceeds net of selling commissions and expenses of $0.6 million under the Series B preferred equity distribution agreement. As of September 30, 2021, we had 1,623,242 shares of Series B Preferred stock available for sale under the Series B preferred equity distribution agreement.

REIT Distribution Requirements

We have elected to be taxed as a REIT under the Internal Revenue Code.  As a REIT, we are required to distribute annually 90% of our REIT taxable income (subject to certain adjustments) to our shareholders.  So long as we continue to qualify as a REIT, we will generally not be subject to U.S. federal or state corporate income taxes on our taxable income that we distribute to our shareholders on a timely basis.  At present, it is our intention to distribute 100% of our taxable income, although we will not be required to do so. We intend to make distributions of our taxable income within the time limits prescribed by the Internal Revenue Code, which may extend into the subsequent taxable year.

Off-Balance Sheet Arrangements and Other Commitments

As of September 30, 2021 and December 31, 2020, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance, or special purpose or VIEs, established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Our economic interests held in unconsolidated VIEs are generally limited in nature to those of a passive holder of beneficial interests in securitized financial assets. As of September 30, 2021 and December 31, 2020, we had consolidated for financial reporting purposes one securitization trust for which we determined that our investment provided us with both (i) the power to direct the activities that most significantly impact the economic performance of the VIE and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.  We were not required to consolidate for financial reporting purposes any other VIEs as of September 30, 2021 and December 31, 2020, as we did not have the power to direct the activities that most significantly impact the economic performance of such entities.

As of September 30, 2021 and December 31, 2020, we had not guaranteed any obligations of unconsolidated entities.  As of September 30, 2021, we had not entered into any commitment or intent to provide funding to unconsolidated entities other than the aforementioned asset-backed revolving credit facility funding commitment.  As of December 31, 2020, we had not entered into any commitment or intent to provide funding to unconsolidated entities.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk is the exposure to loss resulting from changes in market factors such as interest rates, foreign currency exchange rates, commodity prices, equity prices and other market changes that affect market risk sensitive instruments. The primary market risks that we are exposed to are interest rate risk, prepayment risk, extension risk, spread risk, credit risk, liquidity risk and regulatory risk. See “Item 1 — Business” in our Annual Report on Form 10-K for the year ended December 31, 2020 for discussion of our risk management strategies related to these market risks. The following is additional information regarding certain of these market risks.

Interest Rate Risk

We are exposed to interest rate risk in our agency MBS portfolio. Our investments in agency MBS are financed with short-term borrowing facilities, such as repurchase agreements, which are interest rate sensitive financial instruments. Our exposure to interest rate risk fluctuates based upon changes in the level and volatility of interest rates, mortgage prepayments, and in the shape and slope

51

of the yield curve, among other factors. Through the use of interest rate hedging instruments, we attempt to economically hedge a portion of our exposure to changes, attributable to changes in benchmark interest rates, in agency MBS fair values and future interest cash flows on our short-term financing arrangements. Our primary interest rate hedging instruments include interest rate swaps as well as U.S. Treasury note futures, options on U.S. Treasury note futures, and options on agency MBS. Historically, we have also utilized Eurodollar futures and interest rate swap futures.

Changes in both short- and long-term interest rates affect us in several ways, including our financial position. As interest rates increase, the fair value of fixed-rate agency MBS may be expected to decline, prepayment rates may be expected to decrease and duration may be expected to extend. However, an increase in interest rates results in an increase in the fair value of our interest rate hedging instruments. Conversely, if interest rates decline, the fair value of fixed-rate agency MBS is generally expected to increase while the fair value of our interest rate hedging instruments is expected to decline. We also manage our interest rate risk through investment allocation between our agency MBS and MSR related assets.  As interest rates rise, the value of our MSR financing receivables is generally expected to increase due to lower expectations of prepayments in the referenced pools of mortgage loans.  Conversely, as interest rates fall, the value of MSR financing receivables is generally expected to decline due to higher expectations of prepayments in the referenced pools of mortgage loans.  Accordingly, our MSR financing receivables that derive value from the value of a related MSR can be a fair value hedge of our fixed-rate agency MBS.

The tables that follow illustrate the estimated change in fair value for our current investments in agency MBS, MSR financing receivable and derivative instruments under several hypothetical scenarios of interest rate movements. For the purposes of this illustration, interest rates are defined by the U.S. Treasury yield curve. Changes in fair value are measured as percentage changes from their respective fair values presented in the column labeled “Value.” Our estimate of the change in the fair value of agency MBS is based upon the same assumptions we use to manage the impact of interest rates on the portfolio. The interest rate sensitivity of our agency MBS and TBA commitments is derived from The Yield Book, a third-party model. The interest rate sensitivity of our MSR financing receivable is derived from an internal model.  Actual results could differ significantly from these estimates. The effective durations are based on observed fair value changes, as well as our own estimate of the effect of interest rate changes on the fair value of the investments, including assumptions regarding prepayments based, in part, on age and interest rate of the mortgages underlying the agency MBS, prior exposure to refinancing opportunities, and an overall analysis of historical prepayment patterns under a variety of historical interest rate conditions.

The interest rate sensitivity analyses illustrated by the tables that follow have certain limitations, most notably the following:

• The 50 and 100 basis point upward and downward shocks to interest rates that are applied in the analyses represent parallel shocks to the forward yield curve. The analyses do not consider the sensitivity of stockholders’ equity to changes in the shape or slope of the forward yield curve.

• The analyses assume that spreads remain constant and, therefore, do not reflect an estimate of the impact that changes in spreads would have on the value of our MBS investments or our LIBOR- or SOFR-based derivative instruments, such as our interest rate swap agreements.

• The analyses assume a static portfolio and do not reflect activities and strategic actions that management may take in the future to manage interest rate risk in response to significant changes in interest rates or other market conditions.

• The yield curve that results from applying an instantaneous parallel decrease in interest rates reflects an interest rate of less than 0% in certain points of the curve.  The results of the analyses included in the tables below reflect the effect of these negative interest rates.

• The analyses do not reflect any estimated changes in our income tax provision.

• The analyses do not reflect any estimated changes in the fair value of our mortgage credit investments or single-family residential properties.

Spread Risk

Our mortgage investments expose us to “spread risk.”  Spread risk, also known as “basis risk,” is the risk of an increase in the spread between market participants’ required rate of return (or “market yield”) on our mortgage investments and prevailing benchmark interest rates, such as the U.S. Treasury or interest rate swap rates.

The spread risk inherent to our investments in agency MBS and the resulting fluctuations in fair value of these securities can occur independent of changes in prevailing benchmark interest rates and may relate to other factors impacting the mortgage and fixed income markets, such as actual or anticipated monetary policy actions by the U. S. Federal Reserve, liquidity, or changes in market participants’ required rates of return on different assets. While we use interest rate hedging instruments to attempt to mitigate the sensitivity of our net book value to changes in prevailing benchmark interest rates, such instruments are generally not designed to mitigate spread risk inherent to our investment in agency MBS. Consequently, the value of our agency MBS and, in turn, our net book value, could decline independent of changes in interest rates.

The tables that follow illustrate the estimated change in fair value for our investments in agency MBS and TBA commitments under several hypothetical scenarios of agency MBS spread movements. Changes in fair value are measured as percentage changes from their respective fair values presented in the column labeled “Value.” The sensitivity of our agency MBS and TBA commitments to changes in MBS spreads is derived from The Yield Book, a third-party model. The analysis to follow reflects an assumed spread duration for our investment in agency MBS of 6.3 years, which is a model-based assumption that is dependent upon the size and composition of our investment portfolio as well as economic conditions present as of September 30, 2021.

Credit Risk

Unlike our agency MBS investments, our mortgage credit investments do not carry a credit guarantee from a GSE or government agency.  Accordingly, our mortgage credit investments expose us to credit risk.  Credit risk, sometimes referred to as non-performance or non-payment risk, is the risk that we will not receive, in full, the contractually required principal or interest cash flows stemming from our investments due to an underlying borrower’s or issuer’s default on their obligation.  Upon a mortgage loan borrower’s default, a foreclosure sale or other liquidation of the underlying mortgaged property will result in a credit loss if the liquidation proceeds fall short of the mortgage loan’s unpaid principal balance and unpaid accrued interest.

Some of our mortgage credit investments have credit enhancements that mitigate our exposure to the credit risk of the underlying mortgage loans.  Credit losses incurred on the underlying mortgage loans collateralizing our investments in non-agency MBS are allocated on a “reverse sequential” basis. Accordingly, any credit losses realized on the underlying mortgage loans are first absorbed by the beneficial interests subordinate to our non-agency MBS, if any, to the extent of their respective principal balance, prior to being allocated to our investments.

Other of our non-agency MBS investments represent “first loss” positions.  Accordingly, for such investments, credit losses realized on the underlying pool of mortgage loans are first allocated to the Company’s security, to the extent of its principal balance, prior to being allocated to the respective securitization’s more senior credit positions.

We accept exposure to credit risk at levels we deem prudent within our overall investment strategy and our evaluation of the potential risk-adjusted returns.  We attempt to manage our exposure to credit risk through prudent asset selection resulting from pre-acquisition due diligence, ongoing performance monitoring subsequent to acquisition, and the disposition of assets for which we identify negative credit trends.  

There is no guarantee that our attempts to manage our credit risk will be successful.  We could experience substantial losses if the credit performance of the mortgage loans to which we are exposed falls short of our expectations.

Inflation

Virtually all of our assets and liabilities are interest rate sensitive in nature. 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. Our financial statements are prepared in accordance with GAAP and our distributions are determined by our Board of Directors in its sole discretion pursuant to our variable dividend policy; in each case, our activities and balance sheet are measured with reference to fair value without considering inflation.

Item 4. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, our management, with the participation of our Chief Executive Officer, J. Rock Tonkel, Jr., and our Chief Financial Officer, Richard E. Konzmann, carried out an evaluation of the effectiveness of our disclosure controls and procedures (as defined under Rule 13a-15(e) under the Exchange Act) pursuant to Rule 13a-15(b) of the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective to ensure 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 SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding disclosure.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

We are from time to time involved in civil lawsuits, legal proceedings and arbitration matters that we consider to be in the ordinary course of our business. There can be no assurance that these matters individually or in the aggregate will not have a material adverse effect on our financial condition or results of operations in a future period. We are also subject to the risk of litigation, including litigation that may be without merit. As we intend to actively defend such litigation, significant legal expenses could be incurred. An adverse resolution of any future litigation against us could materially affect our financial condition, results of operations and liquidity. Furthermore, we operate in highly-regulated markets that currently are under intense regulatory scrutiny, and we have received, and we expect in the future that we may receive, inquiries and requests for documents and information from various federal, state and foreign regulators. In addition, one or more of our subsidiaries have received requests to repurchase loans from various parties in connection with the former securitization business conducted by a subsidiary. We believe that the continued scrutiny of MBS, structured finance, and derivative market participants increases the risk of additional inquiries and requests from regulatory or enforcement agencies and other parties. We cannot provide any assurance that these inquiries and requests will not result in further investigation of or the initiation of a proceeding against us or that, if any such investigation or proceeding were to arise, it would not materially adversely affect our Company.

Item 1A. Risk Factors

For information regarding factors that could affect our results of operations, financial condition and liquidity, see the risk factors discussed in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020.

The following risk factor should be read in conjunction with the risk factors contained in our Annual Report on Form 10-K for the year ended December 31, 2020.

We are exposed to certain risks related to our investments in SFR homes.

Our investments in SFR homes expose us to certain risks (including risks that differ from the risks associated with the other assets included in our investment portfolio), including among others:

• Ability to identify attractive tenants. Our success depends, in large part, upon our ability to attract and retain qualified tenants. This will depend, in turn, upon our ability, through a third-party investment firm, to screen applicants, identify good residents, avoid tenants who may default, and the willingness of our tenants to renew their leases. When properties are vacant, we are not earning rental income and incur maintenance costs as well as turnover costs associated with re-leasing the properties, such as marketing and leasing commissions. Additionally, if we have to evict tenants, we will incur legal costs and may have renovation costs if the tenants don’t properly maintain the properties or cause damage to the properties.

• Assumptions regarding, and conditions in, our targeted markets. The success of our SFR strategy will depend upon many factors including, but not limited to: the availability of properties that meet our investment criteria and our ability to acquire such properties at favorable prices; our ability to avoid overpaying for properties and avoid impairment charges on such assets; real estate appreciation or depreciation in our target markets; the condition of our properties; our ability to contain renovation, maintenance, marketing and other operating costs for our properties; our ability to maintain high occupancy rates and target rent levels; general economic conditions in our target markets, such as changes in employment and household earnings and expenses; the effects of rent controls, stabilization laws and other laws or regulations regarding rental rates and tenant rights; and changes in, and changes in enforcement of, laws, regulations and government policies including health, safety, environmental, property, zoning and tax laws.

• Significant competition. There is significant competition for SFR homes. Within the past several years, several entities have entered the SFR market and attempted to acquire and operate SFR properties on a large-scale basis and to achieve attractive yields employing technology through a disciplined approach to acquisitions and leasing, marketing and management. Many of our competitors may be larger and have greater financial, technical, leasing, marketing and other resources than we do, which may affect our ability to acquire our target properties at attractive prices and attract quality tenants.

These conditions and risks, if experienced by us, could have a material adverse impact on our ability to successfully execute our SFR investment strategy.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Organization and Basis of Presentation

Note 1. Organization and Basis of Presentation

Arlington Asset Investment Corp. (“Arlington Asset”) and its consolidated subsidiaries (unless the context otherwise provides, collectively, the “Company”) is an investment firm that focuses primarily on investing in mortgage related assets and residential real estate.  The Company’s investment capital is currently allocated between agency mortgage-backed securities (“MBS”), mortgage servicing right (“MSR”) related assets, mortgage credit investments and single-family residential (“SFR”) properties.

The Company’s agency MBS consist of residential mortgage pass-through certificates for which the principal and interest payments are guaranteed by either a U.S. government sponsored enterprise (“GSE”), such as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or by a U.S. government agency, such as the Government National Mortgage Association (“Ginnie Mae”).  The Company’s MSR related assets represent investments for which the return is based on the economic performance of a pool of specific MSRs.  The Company’s mortgage credit investments generally include investments in mortgage loans secured by either residential or commercial real property or MBS collateralized by residential or commercial mortgage loans (“non-agency MBS”).  The principal and interest of the Company’s mortgage credit investments are not guaranteed by a GSE or a U.S government agency.  The Company’s SFR investment strategy is to acquire, lease and operate single-family residential homes as rental properties.

Arlington Asset is a Virginia corporation. The Company is internally managed and does not have an external investment advisor.

The Company has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). As a REIT, the Company is required to distribute annually 90% of its REIT taxable income (subject to certain adjustments). So long as the Company continues to qualify as a REIT, it will generally not be subject to U.S. Federal or state corporate income taxes on its taxable income that it distributes to its shareholders on a timely basis. At present, it is the Company’s intention to distribute 100% of its taxable income, although the Company will not be required to do so. The Company intends to make distributions of its taxable income within the time limits prescribed by the Internal Revenue Code, which may extend into the subsequent taxable year.

The unaudited interim consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X. The Company’s unaudited interim consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

The Company’s consolidated financial statements include the accounts of Arlington Asset and all other entities in which the Company has a controlling financial interest. All intercompany accounts and transactions have been eliminated in consolidation.

The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect amounts reported in the consolidated financial statements. Although the Company bases these estimates and assumptions on historical experience and all other reasonably available information that the Company believes to be relevant under the circumstances, such estimates frequently require management to exercise significant subjective judgment about matters that are inherently uncertain. Actual results may differ from these estimates materially.

Certain amounts in the consolidated financial statements and notes for prior periods have been reclassified to conform to the current year’s presentation. These reclassifications had no impact on the previously reported net income, total assets or total liabilities.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Cash Equivalents

Cash equivalents include demand deposits with banks, money market accounts and highly liquid investments with original maturities of three months or less. As of September 30, 2021 and December 31, 2020, approximately 64% and 99%, respectively, of

the Company’s cash equivalents were invested in money market funds that invest primarily in U.S. Treasuries and other securities backed by the U.S. government.

Investment Security Purchases and Sales

Purchases and sales of investment securities are recorded on the settlement date of the transfer unless the trade qualifies as a “regular-way” trade and the associated commitment qualifies for an exemption from the accounting guidance applicable to derivative instruments. A regular-way trade is an investment security purchase or sale transaction that is expected to settle within the period of time following the trade date that is prevalent or traditional for that specific type of security. Any amounts payable or receivable for unsettled security trades are recorded as “sold securities receivable” or “purchased securities payable” in the consolidated balance sheets.

Interest Income Recognition for Investments in Agency MBS and Mortgage Loans of a Consolidated VIE

The Company recognizes interest income for its investments in agency MBS and mortgage loans of a consolidated variable interest entity (“VIE”) by applying the “interest method” permitted by GAAP, whereby purchase premiums and discounts are amortized and accreted, respectively, as an adjustment to contractual interest income accrued at each investment’s stated interest rate. The interest method is applied at the individual instrument level based upon each instrument’s effective interest rate. The Company calculates each instrument’s effective interest rate at the time of purchase or initial recognition by solving for the discount rate that equates the present value of that instrument's remaining contractual cash flows (assuming no principal prepayments) to its purchase cost. Because each instrument’s effective interest rate does not reflect an estimate of future prepayments, the Company refers to this manner of applying the interest method as the “contractual effective interest method.” When applying the contractual effective interest method to its investments in agency MBS and mortgage loans of a consolidated VIE, as principal prepayments occur, a proportional amount of the unamortized premium or unaccreted discount is recognized in interest income such that the contractual effective interest rate on any remaining security or loan balance is unaffected.

For mortgage loans of a consolidated VIE, the Company ceases the accrual of interest income (i.e., places the loan in non-accrual status) when it believes collectability of principal and interest in full is not reasonably assured, which generally occurs when a loan is three or more monthly payments past due, unless the loan is well secured and in the process of collection based upon an individual loan assessment.  When a loan is placed in non-accrual status, all accrued but uncollected contractual interest as well as any discount accreted during the period of delinquency are reversed.  While a loan is in non-accrual status, the Company recognizes interest income only when interest payments occur.

Interest Income Recognition for Investments in Mortgage Credit Securities and MSR Financing Receivables

The Company recognizes interest income for its investments in mortgage credit securities and MSR financing receivables by applying the prospective level-yield methodology required by GAAP for financial assets that are either not of high credit quality at the time of acquisition or can be contractually prepaid or otherwise settled in such a way that the Company would not recover substantially all of its recorded investment.  The amount of periodic interest income recognized is determined by applying the investment’s effective interest rate to its amortized cost basis (or “reference amount”). At the time of acquisition, the investment’s effective interest rate is calculated by solving for the single discount rate that equates the present value of the Company’s best estimate of the amount and timing of the cash flows expected to be collected from the investment to its purchase cost. To prepare its best estimate of cash flows expected to be collected, the Company develops a number of assumptions about the future performance of the pool of mortgage loans that serve as collateral for its investment, including assumptions about the timing and amount of prepayments and credit losses.  In each subsequent quarterly reporting period, the amount and timing of cash flows expected to be collected from the investment are re-estimated based upon current information and events. The following table provides a description of how periodic changes in the estimate of cash flows expected to be collected affect interest income recognition prospectively for investments in mortgage credit securities and MSR financing receivables:

Scenario:	Effect on Interest Income Recognition for Investments in Mortgage Credit Securities and MSR Financing Receivables:
A positive change in cash flows occurs. Actual cash flows exceed prior estimates and/or a positive change occurs in the estimate of expected remaining cash flows.	A revised effective interest rate is calculated and applied prospectively such that the positive change in cash flows will be recognized as incremental interest income over the remaining life of the investment.
	The amount of periodic interest income recognized over the remaining life of the investment will be reduced accordingly. Generally, the investment’s effective interest rate is reduced accordingly and applied on a prospective basis.  However, if the revised effective interest rate is negative, the investment’s existing effective interest rate is retained while the reference amount to which the existing effective interest rate will be prospectively applied is reduced to the present value of cash flows expected to be collected, discounted at the investment’s existing effective interest rate.
An adverse change in cash flows occurs. Actual cash flows fall short of prior estimates and/or an adverse change occurs in the estimate of expected remaining cash flows.

Recent Accounting Pronouncements

The following table provides a brief description of recently issued accounting pronouncements and their actual or expected effect on the Company’s consolidated financial statements:

Standard	Description	Date of Adoption	Effect on the Consolidated Financial Statements
Recently Issued Accounting Guidance Not Yet Adopted
ASU Nos. 2020-04 and 2021-01, Reference Rate Reform (Topic 848)	The amendments in these updates provide optional practical expedients and exceptions for applying GAAP to the modification of receivables, debt or lease contracts as well as cash flow and fair value hedge accounting relationships that reference a rate, such as the London Interbank Offered Rate (“LIBOR”), that is expected to be discontinued because of reference rate reform. The practical expedients and exceptions provided by these updates are effective from March 12, 2020 through December 31, 2022.	Not yet adopted.	To date, the Company has not made any modifications to contracts due to reference rate reform. The Company has not elected to apply hedge accounting for financial reporting purposes. The Company does not currently expect the adoption of ASU Nos. 2020-04 and 2021-01 to have an effect on its consolidated financial statements.

Agency MBS

Investments in MBS

Note 3. Investments in Agency MBS

The Company has elected to classify its investments in agency MBS as trading securities.  Accordingly, the Company’s investments in agency MBS are reported in the accompanying consolidated balance sheets at fair value.  As of September 30, 2021 and December 31, 2020, the fair value of the Company’s investments in agency MBS was $637,718 and $970,880, respectively. As of

Investments in MSR Financing Receivables

Note 6. Investments in MSR Financing Receivables

The Company does not hold the requisite licenses to purchase or hold MSRs directly.  However, the Company has entered into agreements with a licensed, GSE approved residential mortgage loan servicer that enable the Company to garner the economic return of an investment in an MSR purchased by the mortgage servicing counterparty through an MSR financing transaction.  Under the terms of the arrangement, for an MSR acquired by the mortgage servicing counterparty (i) the Company purchases the “excess servicing spread” from the mortgage servicer counterparty, entitling the Company to monthly distributions of the servicing fees collected by the mortgage servicing counterparty in excess of 12.5 basis points per annum (and to distributions of corresponding proceeds of sale of the MSRs), and (ii) the Company funds the balance of the MSR purchase price to the parent company of the mortgage servicing counterparty and, in exchange, has an unsecured right to payment of certain amounts determined by reference to the MSR, generally equal to the servicing fee revenue less the excess servicing spread and the costs of servicing (and to distributions of corresponding proceeds of sale of the MSRs), net of fees earned by the mortgage servicing counterparty and its affiliates including an incentive fee equal to a percentage of the total return of the MSR in excess of a hurdle rate of return.  At the Company’s election, the mortgage servicing counterparty could utilize leverage on the MSRs that are subject to the Company’s MSR financing receivables to finance the purchase of additional MSRs to increase potential returns to the Company.   Under the arrangement, the Company is obligated to provide funds to the mortgage servicing counterparty to fund its advances of delinquent payments on the serviced pool of mortgage loans with the mortgage servicing counterparty required to return to the Company any subsequent servicing advances collected.  The Company has committed to invest a total minimum of $50,000 in capital with the counterparty with $25,000 of the minimum commitment expiring on December 31, 2023 and $25,000 of the minimum commitment expiring on April 1, 2024.

Under GAAP, the Company accounts for transactions executed under its arrangement as financing transactions and reflects the associated financing receivables in the line item “MSR financing receivables” on its consolidated balance sheets.  The Company has elected to account for its MSR financing receivables at fair value with changes in fair value that are not attributed to interest income recognized as a component of “investment gain (loss), net” in the accompanying consolidated statements of comprehensive income.  As described in further detail in “Note 2. Summary of Significant Accounting Policies,” the Company recognizes interest income for MSR financing receivables by applying the prospective level-yield methodology required by GAAP for financial assets that are either not of high credit quality at the time of acquisition or can be contractually prepaid or otherwise settled in such a way that the Company would not recover substantially all of its recorded investment.

As of September 30, 2021 and December 31, 2020, the fair value of the Company’s investments in MSR financing receivables was $112,834 and $9,346, respectively. The following table presents activity related to the carrying value of the Company’s investments in MSR financing receivables for the periods indicated:

Investments in Single-Family Residential Properties

Note 7. Investments in Single-Family Residential Properties

The Company is party to an agreement with a third-party investment firm to identify, acquire and manage investments in SFR properties on behalf of the Company.  Under the terms of the agreement, the Company has committed to fund up to $50,000 of capital to fund the acquisition of SFR properties.  Under the terms of the agreement, the Company is obligated to pay the third-party firm a minimum fee plus an incentive fee equal to a percentage of the total investment return in excess of a hurdle rate of return.  Under the terms of the agreement, if the Company were to terminate the commitment, the Company would incur termination fee equal to a fixed amount less inception to date minimum fees paid to the third-party firm.

The Company’s investments in SFR properties are initially recognized on the settlement date of their acquisition at cost.  The Company allocates the initial acquisition cost of each property to land and building on the basis of their relative fair values at the time of acquisition.  To determine the relative fair value of land and building at the time of acquisition, the Company uses available market data, such as property specific county tax assessment records.

Subsequent to the acquisition of a property, expenditures which improve or extend the life of the property are capitalized as a component of the property’s cost basis.  Expenditures for ordinary maintenance and repairs are recognized as an expense as incurred and are reported as a component of “single-family property operating expenses” in the Company’s consolidated statements of comprehensive income.

The Company subsequently recognizes depreciation of each property’s buildings and capitalized improvements over the expected useful lives of those assets.  The Company calculates depreciation on a straight-line basis over a useful life of 27.5 years for buildings and useful lives ranging from five to 27.5 years for capitalized improvements.  The Company reports depreciation expense as a component of “single-family property operating expenses” in the Company’s consolidated statements of comprehensive income.

As of September 30, 2021, the Company had investments in 33 SFR properties for a total cost of $9,419, all of which were acquired in September 2021.  During the three and nine months ended September 30, 2021, the Company recognized $12 of depreciation expense related to its SFR properties.  The following table summarizes the Company’s net carrying amount of its SFR properties by component as of the dates indicated:

	September 30, 2021			December 31, 2020
Investments in single-family residential real estate:

Consolidation of Variable Interest Entities

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Consolidation of Variable Interest Entities

Note 8. Consolidation of Variable Interest Entities

The vehicles that issue the Company’s investments in securitized mortgage assets are considered VIEs. The Company is required to consolidate any VIE in which it holds a variable interest if it determines that it holds a controlling financial interest in the VIE and is, therefore, determined to be the primary beneficiary of the VIE.  The Company is determined to be the primary beneficiary of a VIE in which it holds a variable interest if it both (i) holds the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.  The economic performance of the trusts that issue the Company’s investments in securitized mortgage assets is most significantly impacted by the performance of the mortgage loans that are held by the trusts.  The party that is determined to have the most power to direct the loss mitigation actions that are taken with respect to delinquent or otherwise troubled mortgage loans held by the trust is, therefore, deemed to hold the most power to direct the activities that most significantly impact the trust’s economic performance.  As a passive investor, the Company does not have the power to direct the loss mitigation activities of most of the trusts that have issued its securitized mortgage assets.  

On September 30, 2020, the Company acquired for $10,693 an investment that represents a majority interest in the first loss position of a securitized pool of business purpose residential mortgage loans. As majority holder of the first loss position, the Company is required to approve any material loss mitigation action proposed by the servicer with respect to a troubled loan.  The Company also has the option (but not the obligation) to purchase delinquent loans from the trust.  As a result of these contractual rights, the Company determined that it is the party with the most power to direct the loss mitigation activities and, therefore, the economic performance of the trust.  As holder of the majority of the first loss position issued by the trust, the Company has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the trust.  Accordingly, the Company determined that it is the primary beneficiary of the trust and consolidated the trust’s assets and liabilities owed to third parties onto its consolidated balance sheets.  The carrying values of the assets and liabilities of the consolidated VIE, net of elimination entries, are as follows as of the dates indicated:

	September 30, 2021			December 31, 2020
Restricted cash of consolidated VIE (1)	$	3,267		$	11,169
Mortgage loans of consolidated VIE, at fair value		16,516			93,283
Interest receivable of consolidated VIE		67			545
Secured debt of consolidated VIE, at fair value		(7,350	)		(93,627	)
Interest payable of consolidated VIE		(52	)		(321	)
Investment in consolidated VIE	$	12,448		$	11,049

<sup>(1)</sup> Restricted cash represents cash collected by the trust that must be used solely to satisfy the liabilities of the VIE in the month following collection.

The pool of mortgage loans and the third-party held debt obligations of the consolidated VIE had aggregate unpaid principal balances of $17,108 and $7,367, respectively, as of September 30, 2021.  The trust is contractually entitled to receive monthly interest payments on each underlying mortgage loan net of a loan-specific servicing and asset management fee that is not remitted to the trust but is, rather, retained by the servicer.  As of September 30, 2021, the weighted average net note rate to which the VIE was entitled and the weighted average coupon rate of the debt obligations of the consolidated VIE were 6.05% and 4.99%, respectively.  The debt of the consolidated VIE has recourse solely to the assets of the VIE; it has no recourse to the general credit of the Company.

The pool of business purpose residential mortgage loans held by the consolidated VIE consists of fixed-rate, short-term, interest-only mortgage loans (with the full amount of principal due at maturity) made to professional real estate investors and are secured by first lien positions in non-owner occupied residential real estate.  The properties that secure these mortgage loans often require construction, repair or rehabilitation.  The repayment of the mortgage loans is often largely based on the ability of the borrower to sell the mortgaged property or to convert the property for rental purposes and obtain refinancing in the form of a longer-term loan.  Pursuant to the terms of certain of the mortgage loans, the borrower may draw upon a specified amount of additional funds as needed in order to finance construction on, or the repair or rehabilitation of, the mortgaged property (referred to as a “construction draw”).  Pursuant to the terms of the securitization transaction, if the monthly principal repayments collected from the mortgage loan pool are insufficient to fund that month’s construction draws, such shortfall is to be funded by the holders of the first loss position on a pro rata basis.  Any construction draws funded by holders of the first loss position accrue interest at the net note rate of the mortgage loan.  The repayment of any construction draws funded by holders of the first loss position takes priority over the senior debt securities with respect to the cash flows collected from the mortgage loan pool in the following month.  As of September 30, 2021, the aggregate unfunded construction draw balance commitment attributable to the Company’s subordinate debt security investment was $1,306.

The Company has elected to account for the mortgage loans and debt of the consolidated VIE at fair value with changes in fair value that are not attributed to interest income or interest expense, respectively, recognized as a component of “investment gain (loss), net” in the accompanying consolidated statements of comprehensive income.

As described in further detail in “Note 2. Summary of Significant Accounting Policies,” the Company recognizes interest income for the mortgage loans of the consolidated VIE by applying the “interest method” permitted by GAAP, whereby the discount

recognized at the initial recognition of each loan is accreted as an adjustment to contractual interest income accrued at the loan’s stated interest rate. The Company ceases the accrual of interest income for a mortgage loan (i.e., places the loan in non-accrual status) when it believes collectability of principal and interest in full is not reasonably assured, which generally occurs when a loan is three or more monthly payments past due, unless the loan is well secured and in the process of collection based upon an individual loan assessment.  Upon placing a loan in non-accrual status, any previously accrued but uncollected interest is derecognized and a corresponding reduction to current period interest income is recorded.  The following table presents information about the accrual status of the mortgage loans of the consolidated VIE as of September 30, 2021:

	Aggregate Fair Value		Aggregate Unpaid Principal Balance		Difference
Less than 90 days past due and in accrual status	$	9,516	$	9,857	$	(341	)
90 days or more past due and in non-accrual status		7,000		7,251		(251	)

Borrowings

Note 9. Borrowings

Repurchase Agreements

The Company finances the purchase of mortgage investments through repurchase agreements, which are accounted for as collateralized borrowing arrangements. In a repurchase transaction, the Company sells a mortgage investment to a counterparty under a master repurchase agreement in exchange for cash and concurrently agrees to repurchase the same asset at a future date in an amount equal to the cash initially exchanged plus an agreed-upon amount of interest. Mortgage investments sold under agreements to repurchase remain on the Company’s consolidated balance sheets because the Company maintains effective control over such assets throughout the duration of the arrangement. Throughout the contractual term of a repurchase agreement, the Company recognizes a “repurchase agreement” liability on its consolidated balance sheets to reflect the obligation to repay to the counterparty the proceeds received upon the initial transfer of the mortgage investment. The difference between the proceeds received by the Company upon the initial transfer of the mortgage investment and the contractually agreed-upon repurchase price is recognized as interest expense ratably over the term of the repurchase arrangement.

Amounts borrowed pursuant to repurchase agreements are equal in value to a specified percentage of the fair value of the pledged collateral. The Company retains beneficial ownership of the pledged collateral throughout the term of the repurchase agreement. The counterparty to the repurchase agreements may require that the Company pledge additional securities or cash as additional collateral to secure borrowings when the value of the collateral declines.

The Company’s MBS repurchase agreement arrangements generally carry a fixed rate of interest and are short-term in nature with contract durations generally ranging from 30 to 60 days, but may be as short as one day or as long as one year.  The Company’s mortgage loan repurchase agreement arrangement has a maturity date of August 25, 2022 and an interest rate that resets monthly at a rate equal to one-month LIBOR plus 2.50%.   Under the terms of the Company’s mortgage loan repurchase agreement, the Company may request extensions of the maturity date of the agreement for up to 364 days, subject to the lender’s approval.

As of September 30, 2021 and December 31, 2020, the Company had no amount at risk with a single repurchase agreement counterparty or lender greater than 10% of equity. The following table provides information regarding the Company’s outstanding repurchase agreement borrowings as of the dates indicated:

Long-Term Secured Debt

On September 28, 2021, McLean SFR Investment, LLC (“McLean SFR”), a wholly-owned subsidiary of Arlington Asset, entered into a loan agreement with a third-party lender to fund McLean SFR’s purchases of SFR properties.  Under the terms of the loan agreement, loan advances may be drawn up to 74% of the fair value of eligible SFR properties up to a maximum loan amount of $150,000.  Advances under the loan agreement may be drawn during the advance period, which ends on the earlier of the date the outstanding principal balance equals the maximum loan amount or March 28, 2023.  The outstanding principal balance is due on October 9, 2026 and advances under the loan agreement bear interest at a fixed rate of 2.76%.  As of September 30, 2021, there were no advances outstanding under the loan agreement.

Through September 28, 2024, the outstanding principal balance may be prepaid in an amount equal to the excess of (i) the sum of the present value of all remaining scheduled payments of principal and interest on the principal amount of the loan being prepaid discounted using a U.S. Treasury rate over (ii) the outstanding principal balance of the loan.  Subsequent to September 28, 2024, the outstanding principal balance may be prepaid in an amount equal to the outstanding principal balance plus accrued interest.

The loan is secured by a first priority interest in all the assets of McLean SFR and a first priority pledge of the equity interest of McLean SFR. If the outstanding principal balance of the loan is greater than 74% of the fair value of the eligible collateral, McLean SFR is required to either pledge additional collateral or prepay the loan in an amount so that the outstanding principal balance does not exceed 74% of the fair value of the eligible collateral.  Under the terms of the loan agreement, if McLean SFR does not maintain a minimum debt service coverage ratio for a specified time period, then all available cash of McLean SFR will be held as additional collateral for the loan amount until the minimum debt service coverage ratio is met.  The obligations under the loan agreement may become recourse to Arlington Asset upon the occurrence of certain enumerated acts committed by McLean SFR or Arlington Asset.  The loan agreement contains a minimum net worth financial covenant of Arlington Asset.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivative Instruments

Note 10. Derivative Instruments

In the normal course of its operations, the Company is a party to financial instruments that are accounted for as derivative instruments. Derivative instruments are recorded at fair value as either “derivative assets” or “derivative liabilities” in the consolidated balance sheets, with all periodic changes in fair value reflected as a component of “investment gain (loss), net” in the consolidated statements of comprehensive income. Cash receipts or payments related to derivative instruments are classified as investing activities within the consolidated statements of cash flows.

Types and Uses of Derivative Instruments

Interest Rate Hedging Instruments

The Company is party to interest rate hedging instruments that are intended to economically hedge changes, attributable to changes in benchmark interest rates, in certain MBS fair values and future interest cash flows on the Company’s short-term financing arrangements. Interest rate hedging instruments may include centrally cleared interest rate swaps, exchange-traded instruments, such as U.S. Treasury note futures, Eurodollar futures, interest rate swap futures and options on futures, and non-exchange-traded

instruments such as options on agency MBS. While the Company uses its interest rate hedging instruments to economically hedge a portion of its interest rate risk, it has not designated such contracts as hedging instruments for financial reporting purposes.

The Company exchanges cash “variation margin” with the counterparties to its interest rate hedging instruments at least on a daily basis based upon daily changes in fair value as measured by the Chicago Mercantile Exchange (“CME”), the central clearinghouse through which those instruments are cleared. In addition, the CME requires market participants to deposit and maintain an “initial margin” amount which is determined by the CME and is generally intended to be set at a level sufficient to protect the CME from the maximum estimated single-day price movement in that market participant’s contracts. However, futures commission merchants may require “initial margin” in excess of the CME’s requirement.  Receivables recognized for the right to reclaim cash initial margin posted in respect of interest rate hedging instruments are included in the line item “deposits” in the accompanying consolidated balance sheets.

The daily exchange of variation margin associated with a centrally cleared or exchange-traded hedging instrument is legally characterized as the daily settlement of the instrument itself, as opposed to a pledge of collateral. Accordingly, the Company accounts for the daily receipt or payment of variation margin associated with its interest rate swaps and futures as a direct reduction to the carrying value of the derivative asset or liability, respectively. The carrying amount of interest rate swaps and futures reflected in the Company’s consolidated balance sheets is equal to the unsettled fair value of such instruments; because variation margin is exchanged on a one-day lag, the unsettled fair value of such instruments generally represents the change in fair value that occurred on the last day of the reporting period.

To-Be-Announced Agency MBS Transactions, Including “Dollar Rolls”

In addition to interest rate hedging instruments that are used for interest rate risk management, the Company is a party to derivative instruments that economically serve as investments, such as forward commitments to purchase fixed-rate “pass-through” agency MBS on a non-specified pool basis, which are known as to-be-announced (“TBA”) securities. A TBA security is a forward commitment for the purchase or sale of a fixed-rate agency MBS at a predetermined price, face amount, issuer, coupon, and stated maturity for settlement on an agreed upon future date. The specific agency MBS that will be delivered to satisfy the TBA trade is not known at the inception of the trade. The specific agency MBS to be delivered is determined 48 hours prior to the settlement date. The Company accounts for TBA securities as derivative instruments because the Company cannot assert that it is probable at inception and throughout the term of an individual TBA commitment that its settlement will result in physical delivery of the underlying agency MBS, or the individual TBA commitment will not settle in the shortest time period possible.

The Company’s agency MBS investment portfolio includes net purchase (or “net long”) positions in TBA securities, which are primarily the result of executing sequential series of “dollar roll” transactions. The Company executes dollar roll transactions as a means of investing in and financing non-specified fixed-rate agency MBS. Such transactions involve effectively delaying (or “rolling”) the settlement of a forward purchase of a TBA agency MBS by entering into an offsetting sale with the same counterparty prior to the settlement date, net settling the “paired-off” positions in cash, and contemporaneously entering, with the same counterparty, another forward purchase of a TBA agency MBS of the same characteristics for a later settlement date. TBA securities purchased for a forward settlement month are generally priced at a discount relative to TBA securities sold for settlement in the current month. This discount, often referred to as the dollar roll “price drop,” reflects compensation for the net interest income (interest income less financing costs) that is foregone as a result of relinquishing beneficial ownership of the MBS for the duration of the dollar roll (also known as “dollar roll income”). By executing a sequential series of dollar roll transactions, the Company is able to create the economic experience of investing in an agency MBS, financed with a repurchase agreement, over a period of time. Forward purchases and sales of TBA securities are accounted for as derivative instruments in the Company’s financial statements. Accordingly, dollar roll income is recognized as a component of “investment gain (loss), net” along with all other periodic changes in the fair value of TBA commitments.

In addition to transacting in net long positions in TBA securities for investment purposes, the Company may also, from time to time, transact in net sale (or “net short”) positions in TBA securities for the purpose of economically hedging a portion of the sensitivity of the fair value of the Company’s investments in agency MBS to changes in interest rates.

In addition to TBA transactions, the Company may, from time to time, enter into commitments to purchase or sell specified agency MBS that do not qualify as regular-way security trades. Such commitments are also accounted for as derivative instruments.

Under the terms of commitments to purchase or sell TBAs or specified agency MBS, the daily exchange of variation margin may occur based on changes in the fair value of the underlying agency MBS if a party to the transaction demands it. Receivables recognized for the right to reclaim cash collateral posted by the Company in respect of agency MBS purchase or sale commitments is included in the line item “deposits” in the accompanying consolidated balance sheets. Liabilities recognized for the obligation to

return cash collateral received by the Company in respect of agency MBS purchase or sale commitments is included in the line item “other liabilities” in the accompanying consolidated balance sheets.

U.S. Treasury Note Futures

The Company may purchase (“long”) or sell (“short”) exchange-traded U.S. Treasury note futures with the objective of economically hedging a portion of its interest rate risk. Upon the maturity date of these futures contracts, the Company has the option to either net settle each contract in cash in an amount equal to the difference between the then-current fair value of the underlying U.S. Treasury note and the contractual sale price inherent to the futures contract, or to physically settle the contract by purchasing or delivering the underlying U.S. Treasury note.

As of September 30, 2021 and December 31, 2020, the Company had no outstanding positions of U.S. Treasury note futures.

Options on U.S. Treasury Note Futures

The Company may purchase or sell exchange-traded options on U.S. Treasury note futures contracts with the objective of economically hedging a portion of the sensitivity of its investments in agency MBS to significant changes in interest rates. The

Company may purchase put or call options which provide the Company with the right to sell to counterparty or purchase from a counterparty U.S. Treasury note futures, and the Company may also write put or call options that provide a counterparty with the option to sell to the Company or buy from the Company U.S. Treasury note futures. The options may be exercised at any time prior to their expiry, and if exercised, may be net settled in cash or through physical receipt or delivery of the underlying futures contracts.

As of September 30, 2021 and December 31, 2020, the Company had no outstanding options on U.S. Treasury note futures contracts.

Offsetting [Abstract]

Offsetting of Financial Assets and Liabilities

Note 11. Offsetting of Financial Assets and Liabilities

The agreements that govern certain of the Company’s derivative instruments and collateralized short-term financing arrangements provide for a right of setoff in the event of default or bankruptcy with respect to either party to such transactions. The Company presents derivative assets and liabilities as well as collateralized short-term financing arrangements on a gross basis.

Receivables recognized for the right to reclaim cash initial margin posted in respect of interest rate derivative instruments are included in the line item “deposits” in the accompanying consolidated balance sheets.

The daily exchange of variation margin associated with a centrally cleared or exchange-traded derivative instrument is legally characterized as the daily settlement of the derivative instrument itself, as opposed to a pledge of collateral. Accordingly, the Company accounts for the daily receipt or payment of variation margin associated with its interest rate swaps and futures as a direct reduction to the carrying value of derivative asset or liability, respectively. The carrying amount of interest rate swaps and futures reflected in the Company’s consolidated balance sheets is equal to the unsettled fair value of such instruments; because variation margin is exchanged on a one-day lag, the unsettled fair value of such instruments generally represents the change in fair value that occurred on the last day of the reporting period.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 12. Fair Value Measurements

Fair Value of Financial Instruments

The accounting principles related to fair value measurements define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial Accounting Standards Board Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, giving the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3) as described below:

Level 1 Inputs -  Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible by the Company at the measurement date;

Level 2 Inputs -  Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and

Level 3 Inputs -  Unobservable inputs for the asset or liability, including significant judgments made by the Company about the assumptions that a market participant would use.

The Company measures the fair value of the following assets and liabilities:

Mortgage investments

Agency MBS - The Company’s investments in agency MBS are classified within Level 2 of the fair value hierarchy. Inputs to fair value measurements of the Company’s investments in agency MBS include price estimates obtained from third-party pricing services.  In determining fair value, third-party pricing services use a market approach. The inputs used in the fair value measurements performed by the third-party pricing services are based upon readily observable transactions for securities with similar characteristics (such as issuer/guarantor, coupon rate, stated maturity, and collateral pool characteristics) occurring on the measurement date. The Company makes inquiries of the third-party pricing sources and reviews their documented valuation methodologies to understand the significant inputs and assumptions used to determine prices. The Company reviews the various third-party fair value estimates and performs procedures to validate their reasonableness, including comparison to recent trading activity for similar securities and an overall review for consistency with market conditions observed as of the measurement date.

Mortgage credit securities – The Company’s investments in residential MBS and commercial MBS are classified within Level 2 of the fair value hierarchy. Inputs to fair value measurements of the Company’s investments in residential and commercial MBS include quoted prices for similar assets in recent market transactions and estimates obtained from third-party pricing sources including pricing services and dealers. In determining fair value, third-party pricing sources use a market approach. The inputs used in the fair value measurements performed by third-party pricing sources are based upon observable transactions for securities with similar characteristics. The Company reviews the third-party fair value estimates and performs procedures to validate their reasonableness, including comparisons to recent trading activity observed for similar securities as well as an internally derived discounted future cash flow measurement.

The Company’s first loss position in a securitized pool of business-purpose residential mortgage loans is classified within Level 3 of the fair value hierarchy.  To measure the fair value of this investment, the Company uses an income approach by preparing an estimate of the present value of the amount and timing of the cash flows expected to be collected from the security over its expected remaining life.  To prepare the estimate of cash flows expected to be collected, the Company uses significant judgment to develop assumptions about the future performance of the pool of mortgage loans that serve as collateral, including assumptions about the timing and amount of credit losses and prepayments.  The significant unobservable inputs to the fair value measurement include the estimated rate of default and loss-given-default for the underlying pool of mortgage loans as well as the discount rate, which represents a market participant’s current required rate of return for a similar instrument.  The following table presents the significant unobservable inputs to the fair value measurement of the Company’s non-agency MBS secured by business-purpose residential mortgage loans as of the periods indicated:

	September 30, 2021			December 31, 2020
Annualized default rate		35.0	%		12.0	%
Loss-given-default		25.0	%		40.0	%
Discount rate		13.0	%		13.9	%

Loans – The Company’s commercial mortgage loan investment is classified within Level 3 of the fair value hierarchy.  To measure the fair value of its mortgage loan investment, the Company uses an income approach by preparing an estimate of the present value of the expected future cash flows of the loan over their expected remaining life, discounted at a current market rate.  The significant unobservable inputs to the fair value measurement of the Company’s mortgage loan investment is the estimated probability of default and the discount rate, which is based on current market yields and interest rate spreads for a similar loan.  As of September 30, 2021, the estimated probability of default and discount rate for the Company’s mortgage loan investment were 0%, and 5.6%, respectively.  As of December 31, 2020, the estimated probability of default and discount rate for the Company’s mortgage loan investment were 0% and 6.3%, respectively.

Mortgage loans and secured debt of consolidated VIE – The Company has elected to apply a fair value measurement practical expedient permitted by GAAP to measure the fair value of the mortgage loans and debt obligations of its consolidated VIE.  The fair value measurement practical expedient is permitted to be applied to consolidated “collateralized financing entities,” which are VIEs for which the financial liabilities of the VIE have contractual recourse solely to the financial assets of the VIE.  Pursuant to the practical expedient, the Company measures the fair value of both the mortgage loans and the debt obligations of its consolidated VIE based upon the fair value of the debt obligations of the VIE, as the fair value of the debt securities issued by the VIE is more observable to the Company than the fair value of the underlying mortgage loans.

The senior debt obligations of the consolidated VIE are classified within Level 2 of the fair value hierarchy.  Inputs to fair value measurements of the senior debt obligations of the consolidated VIE include quoted prices for similar assets in recent market transactions and estimates obtained from third-party pricing sources including pricing services and dealers. In determining fair value, third-party pricing sources use a market approach. The inputs used in the fair value measurements performed by third-party pricing sources are based upon observable transactions for securities with similar characteristics.

The subordinate debt obligation and the mortgage loans of the consolidated VIE are classified within Level 3 of the fair value hierarchy.  To measure the fair value of the subordinate debt obligation of the consolidated VIE, the Company uses an income approach by preparing an estimate of the present value of the amount and timing of the cash flows expected to be collected from the security over its expected remaining life.  To prepare the estimate of cash flows expected to be collected, the Company uses significant judgment to develop assumptions about the future performance of the pool of business-purpose residential mortgage loans that serve as collateral, including assumptions about the timing and amount of credit losses and prepayments.  The significant unobservable inputs to the fair value measurement include the estimated rate of default and loss-given-default for the underlying pool of mortgage loans as well as the discount rate, which represents a market participant’s current required rate of return for a similar instrument.  The following table presents the significant unobservable inputs to the fair value measurement of the subordinate debt obligation as of the periods indicated:

	September 30, 2021			December 31, 2020
Annualized default rate		15.0	%		20.0	%
Loss-given-default		25.0	%		40.0	%
Discount rate		12.0	%		13.9	%

MSR financing receivables – The Company’s MSR financing receivables are classified within Level 3 of the fair value hierarchy.  The Company uses a nationally recognized, independent third-party mortgage analytics and valuation firm to estimate the fair value of the underlying MSRs from which the Company’s MSR financing receivables primarily derive their value. The third-party valuation firm estimates the fair value of the underlying MSRs using a discounted cash flow analysis using their proprietary prepayment models and market analysis.  The Company corroborates the third-party valuation firm’s estimate of the fair value of the underlying MSRs and evaluates the estimate for reasonableness.  The significant unobservable inputs to the fair value measurement of the underlying MSRs include the following:

• the discount rate, which represents a market participant’s current required rate of return for similar MSRs;

• expected rates of prepayment within the serviced pools of mortgage loans; and  

• annual per-loan cost of servicing.

The following table presents the significant unobservable inputs to the fair value measurement of the MSRs underlying the Company’s MSR financing receivables as of September 30, 2021:

	September 30, 2021
Discount rate		9.0	%
Annualized prepayment rate		10.2	%
Annual per-loan cost of servicing (current loans)	$	65.00

Pursuant to the Company’s MSR financing arrangements, upon the consummation of three-year performance periods ending December 31, 2023 and April 1, 2024, the Company’s mortgage servicer counterparty is entitled to an incentive fee payment equal to a percentage of the total return of the underlying MSRs in excess of a hurdle rate of return.  Accordingly, the fair value of the Company’s MSR financing receivables reflects the present value of any expected incentive fee payment that would be owed to its counterparty based upon the current fair value of the underlying MSRs.  As of September 30, 2021, the present value of the expected incentive fee payment reflected in fair value of the Company’s MSR financing receivables was $1,413.

As of December 31, 2020, the fair value of the Company’s MSR financing receivable was its transacted purchase price, which occurred on the measurement date.

Derivative instruments

Exchange-traded derivative instruments - Exchange-traded derivative instruments, which include U.S. Treasury note futures, Eurodollar futures, interest rate swap futures, and options on futures, are classified within Level 1 of the fair value hierarchy as they are measured using quoted prices for identical instruments in liquid markets.

Interest rate swaps - Interest rate swaps are classified within Level 2 of the fair value hierarchy. The fair values of the Company’s centrally cleared interest rate swaps are measured using the daily valuations reported by the clearinghouse through which the instrument was cleared. In performing its end-of-day valuations, the clearinghouse constructs forward interest rate curves (for example, three-month LIBOR or SOFR forward rates) from its specific observations of that day’s trading activity. The clearinghouse uses the applicable forward interest rate curve to develop a market-based forecast of future remaining contractually required cash flows for each interest rate swap. Each market-based cash flow forecast is then discounted using the SOFR curve (sourced from the Federal Reserve Bank of New York) to determine a net present value amount which represents the instrument’s fair value.

Forward-settling purchases and sales of TBA securities – Forward-settling purchases and sales of TBA securities are classified within Level 2 of the fair value hierarchy. The fair value of each forward-settling TBA contract is measured using price estimates obtained from a third-party pricing service, which are based upon readily observable transaction prices occurring on the measurement date for forward-settling contracts to buy or sell TBA securities with the same guarantor, contractual maturity, and coupon rate for delivery on the same forward settlement date as the commitment under measurement.

Other

Long-term unsecured debt - As of September 30, 2021 and December 31, 2020, the carrying value of the Company’s long-term unsecured debt was $85,901 and $73,027, respectively, net of unamortized debt issuance costs, and consists of Senior Notes and trust preferred debt issued by the Company. The Company’s estimate of the fair value of long-term unsecured debt is $84,795 and $69,904 as of September 30, 2021 and December 31, 2020, respectively. The Company’s Senior Notes, which are publicly traded on the New York Stock Exchange, are classified within Level 1 of the fair value hierarchy. Trust preferred debt is classified within Level 2 of the fair value hierarchy as the fair value is estimated based on the quoted prices of the Company’s publicly traded Senior Notes.

Investments in equity securities of publicly-traded companies – As of September 30, 2021 and December 31, 2020, the Company had investments in equity securities of publicly-traded companies at fair value of $5,544 and $10,821, respectively, which is included in the line item “other assets” in the accompanying consolidated balance sheets.  Investments in publicly traded stock are classified within Level 1 of the fair value hierarchy as their fair value is measured based on unadjusted quoted prices in active exchange markets for identical assets.

Investments in equity securities of non-public companies and investment funds – As of September 30, 2021 and December 31, 2020, the Company had investments in equity securities and investment funds measured at fair value of $7,143 and $6,869, respectively, which are included in the line item “other assets” in the accompanying consolidated balance sheets.

Investments in equity securities of non-public companies and investment funds are classified within Level 3 of the fair value hierarchy. The fair values of the Company’s investments in equity securities of non-public companies and investment funds are not readily determinable. Accordingly, the Company estimates fair value by estimating the enterprise value of the investee which it then allocates to the investee’s securities in the order of their preference relative to one another. To estimate the enterprise value of the investee, the Company uses traditional valuation methodologies based on income and market approaches, including the consideration of recent investments in, or tender offers for, the equity securities of the investee, a discounted cash flow analysis and a comparable guideline public company valuation. The primary unobservable inputs used in estimating the fair value of an equity security of a non-public company include (i) a stock price to net asset multiple for similar public companies that is applied to the entity’s net assets, (ii) a discount factor for lack of marketability and control, and (iii) a cost of equity discount rate, used to discount to present value the equity cash flows available for distribution and the terminal value of the entity. As of September 30, 2021, the stock price to net asset multiple for similar public companies, the discount factor for lack of marketability and control, and the cost of equity discount rate used as inputs were 95 percent, 15 percent, and 16 percent, respectively. As of December 31, 2020, the stock price to net asset multiple for similar public companies, the discount factor for lack of marketability and control, and the cost of equity discount rate used as inputs were 95 percent, 10 percent, and 15 percent, respectively. For its investments in investment funds, the Company estimates fair value based upon the investee’s net asset value per share.

Financial assets and liabilities for which carrying value approximates fair value - Cash and cash equivalents, restricted cash, deposits, receivables, repurchase agreements, payables, and other assets (aside from those previously discussed) and liabilities are generally reflected in the consolidated balance sheets at their cost, which, due to the short-term nature of these instruments and their limited inherent credit risk, approximates fair value.

Income Tax Disclosure [Abstract]

Income Taxes

Note 13. Income Taxes

The Company has elected to be taxed as a REIT under the Internal Revenue Code.  As a REIT, the Company is required to distribute annually 90% of its REIT taxable income. So long as the Company continues to qualify as a REIT, it will generally not be subject to U.S. Federal or state corporate income taxes on its taxable income to the extent that it distributes all of its annual taxable income to its shareholders on a timely basis. At present, it is the Company’s intention to distribute 100% of its taxable income, although the Company will not be required to do so. The Company intends to make distributions of its taxable income within the time limits prescribed by the Internal Revenue Code, which may extend into the subsequent taxable year.

As of September 30, 2021, the Company had net operating loss (“NOL”) carryforwards of $150,936 that can be used to offset future taxable ordinary income and reduce its REIT distribution requirements. NOL carryforwards totaling $14,588 expire in 2028 and NOL carryforwards totaling $136,348 have no expiration period. As of September 30, 2021, the Company had net capital loss (“NCL”) carryforwards of $180,948 that can be used to offset future net capital gains. The scheduled expirations of the Company’s NCL carryforwards are $66,862 in 2021, $3,763 in 2022 and $110,323 in 2023.

The Company and subsidiaries have made joint elections to treat certain subsidiaries as taxable REIT subsidiaries (“TRSs”).  In general, a TRS may hold assets and engage in activities that the Company cannot hold or engage in directly and generally may engage in any real estate or non-real estate related business.  As such, each of these TRSs is taxable as a C corporation and subject to federal, state and local income taxes based upon their taxable income. For the three and nine months ended September 30, 2021, the Company recognized a provision for income taxes of $436 and $758, respectively, on the pre-tax net income of its TRSs.

The Company recognizes uncertain tax positions in the financial statements only when it is more-likely-than-not that the position will be sustained upon examination by the relevant taxing authority based on the technical merits of the position. A position

that meets this standard is measured at the largest amount of benefit that will more-likely-than-not be realized upon settlement. A liability is established for differences between positions taken in a tax return and the financial statements. As of September 30, 2021 and December 31, 2020, the Company assessed the need for recording a provision for any uncertain tax position and has made the determination that such provision is not necessary.  If the Company were to incur income tax related interest and penalties, the Company’s policy is to classify them as a component of provision for income taxes.

Shareholder Rights Agreement

On June 1, 2009, the Board of Directors approved a shareholder rights agreement (“Rights Plan”) and the Company’s shareholders approved the Rights Plan at its annual meeting of shareholders on June 2, 2010.  On April 9, 2018, the Board of Directors approved a first amendment to the Rights Plan (“First Amendment”) to extend the term for an additional three years and the Company’s shareholders approved the First Amendment at its annual meeting of shareholders on June 14, 2018.  

Under the terms of the Rights Plan, in general, if a person or group acquires or commences a tender or exchange offer for beneficial ownership of 4.9% or more of the outstanding shares of our Class A common stock upon a determination by our Board of Directors (an “Acquiring Person”), all of our other Class A and Class B common shareholders will have the right to purchase securities from us at a discount to such securities’ fair market value, thus causing substantial dilution to the Acquiring Person.

The Board of Directors adopted the Rights Plan in an effort to protect against a possible limitation on the Company’s ability to use its NOL carryforwards, NCL carryforwards, and built-in losses under Sections 382 and 383 of the Internal Revenue Code. The Company’s ability to use its NOLs, NCLs and built-in losses would be limited if it experienced an “ownership change” under Section 382 of the Internal Revenue Code. In general, an “ownership change” would occur if there is a cumulative change in the ownership of the Company’s common stock of more than 50% by one or more “5% shareholders” during a three-year period. The Rights Plan was adopted to dissuade any person or group from acquiring 4.9% or more of the Company’s outstanding Class A common stock, each, an Acquiring Person, without the approval of the Board of Directors and triggering an “ownership change” as defined by Section 382.

The Rights Plan, as amended, and any outstanding rights will expire at the earliest of (i) June 4, 2022, (ii) the time at which the rights are redeemed or exchanged pursuant to the Rights Plan, (iii) the repeal of Section 382 and 383 of the Internal Revenue Code or any successor statute if the Board of Directors determines that the Rights Plan is no longer necessary for the preservation of the applicable tax benefits, or (iv) the beginning of a taxable year to which the Board of Directors determines that no applicable tax benefits may be carried forward.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2021

Cash Equivalents

Cash Equivalents

Cash equivalents include demand deposits with banks, money market accounts and highly liquid investments with original maturities of three months or less. As of September 30, 2021 and December 31, 2020, approximately 64% and 99%, respectively, of

the Company’s cash equivalents were invested in money market funds that invest primarily in U.S. Treasuries and other securities backed by the U.S. government.

Investment Security Purchases and Sales

Investment Security Purchases and Sales

Purchases and sales of investment securities are recorded on the settlement date of the transfer unless the trade qualifies as a “regular-way” trade and the associated commitment qualifies for an exemption from the accounting guidance applicable to derivative instruments. A regular-way trade is an investment security purchase or sale transaction that is expected to settle within the period of time following the trade date that is prevalent or traditional for that specific type of security. Any amounts payable or receivable for unsettled security trades are recorded as “sold securities receivable” or “purchased securities payable” in the consolidated balance sheets.

The Company has elected to account for the mortgage loans and debt of the consolidated VIE at fair value with changes in fair value that are not attributed to interest income or interest expense, respectively, recognized as a component of “investment gain (loss), net” in the accompanying consolidated statements of comprehensive income.

Interest Income Recognition for Investments in Agency MBS and Mortgage Loans of a Consolidated VIE

Interest Income Recognition for Investments in Agency MBS and Mortgage Loans of a Consolidated VIE

The Company recognizes interest income for its investments in agency MBS and mortgage loans of a consolidated variable interest entity (“VIE”) by applying the “interest method” permitted by GAAP, whereby purchase premiums and discounts are amortized and accreted, respectively, as an adjustment to contractual interest income accrued at each investment’s stated interest rate. The interest method is applied at the individual instrument level based upon each instrument’s effective interest rate. The Company calculates each instrument’s effective interest rate at the time of purchase or initial recognition by solving for the discount rate that equates the present value of that instrument's remaining contractual cash flows (assuming no principal prepayments) to its purchase cost. Because each instrument’s effective interest rate does not reflect an estimate of future prepayments, the Company refers to this manner of applying the interest method as the “contractual effective interest method.” When applying the contractual effective interest method to its investments in agency MBS and mortgage loans of a consolidated VIE, as principal prepayments occur, a proportional amount of the unamortized premium or unaccreted discount is recognized in interest income such that the contractual effective interest rate on any remaining security or loan balance is unaffected.

For mortgage loans of a consolidated VIE, the Company ceases the accrual of interest income (i.e., places the loan in non-accrual status) when it believes collectability of principal and interest in full is not reasonably assured, which generally occurs when a loan is three or more monthly payments past due, unless the loan is well secured and in the process of collection based upon an individual loan assessment.  When a loan is placed in non-accrual status, all accrued but uncollected contractual interest as well as any discount accreted during the period of delinquency are reversed.  While a loan is in non-accrual status, the Company recognizes interest income only when interest payments occur.

Interest Income Recognition for Investments in Mortgage Credit Securities and MSR Financing Receivables

Interest Income Recognition for Investments in Mortgage Credit Securities and MSR Financing Receivables

The Company recognizes interest income for its investments in mortgage credit securities and MSR financing receivables by applying the prospective level-yield methodology required by GAAP for financial assets that are either not of high credit quality at the time of acquisition or can be contractually prepaid or otherwise settled in such a way that the Company would not recover substantially all of its recorded investment.  The amount of periodic interest income recognized is determined by applying the investment’s effective interest rate to its amortized cost basis (or “reference amount”). At the time of acquisition, the investment’s effective interest rate is calculated by solving for the single discount rate that equates the present value of the Company’s best estimate of the amount and timing of the cash flows expected to be collected from the investment to its purchase cost. To prepare its best estimate of cash flows expected to be collected, the Company develops a number of assumptions about the future performance of the pool of mortgage loans that serve as collateral for its investment, including assumptions about the timing and amount of prepayments and credit losses.  In each subsequent quarterly reporting period, the amount and timing of cash flows expected to be collected from the investment are re-estimated based upon current information and events. The following table provides a description of how periodic changes in the estimate of cash flows expected to be collected affect interest income recognition prospectively for investments in mortgage credit securities and MSR financing receivables:

Scenario:	Effect on Interest Income Recognition for Investments in Mortgage Credit Securities and MSR Financing Receivables:
A positive change in cash flows occurs. Actual cash flows exceed prior estimates and/or a positive change occurs in the estimate of expected remaining cash flows.	A revised effective interest rate is calculated and applied prospectively such that the positive change in cash flows will be recognized as incremental interest income over the remaining life of the investment.
	The amount of periodic interest income recognized over the remaining life of the investment will be reduced accordingly. Generally, the investment’s effective interest rate is reduced accordingly and applied on a prospective basis.  However, if the revised effective interest rate is negative, the investment’s existing effective interest rate is retained while the reference amount to which the existing effective interest rate will be prospectively applied is reduced to the present value of cash flows expected to be collected, discounted at the investment’s existing effective interest rate.
An adverse change in cash flows occurs. Actual cash flows fall short of prior estimates and/or an adverse change occurs in the estimate of expected remaining cash flows.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

The following table provides a brief description of recently issued accounting pronouncements and their actual or expected effect on the Company’s consolidated financial statements:

Standard	Description	Date of Adoption	Effect on the Consolidated Financial Statements
Recently Issued Accounting Guidance Not Yet Adopted
ASU Nos. 2020-04 and 2021-01, Reference Rate Reform (Topic 848)	The amendments in these updates provide optional practical expedients and exceptions for applying GAAP to the modification of receivables, debt or lease contracts as well as cash flow and fair value hedge accounting relationships that reference a rate, such as the London Interbank Offered Rate (“LIBOR”), that is expected to be discontinued because of reference rate reform. The practical expedients and exceptions provided by these updates are effective from March 12, 2020 through December 31, 2022.	Not yet adopted.	To date, the Company has not made any modifications to contracts due to reference rate reform. The Company has not elected to apply hedge accounting for financial reporting purposes. The Company does not currently expect the adoption of ASU Nos. 2020-04 and 2021-01 to have an effect on its consolidated financial statements.

Consolidation of Variable Interest Entities

The vehicles that issue the Company’s investments in securitized mortgage assets are considered VIEs. The Company is required to consolidate any VIE in which it holds a variable interest if it determines that it holds a controlling financial interest in the VIE and is, therefore, determined to be the primary beneficiary of the VIE.  The Company is determined to be the primary beneficiary of a VIE in which it holds a variable interest if it both (i) holds the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.  The economic performance of the trusts that issue the Company’s investments in securitized mortgage assets is most significantly impacted by the performance of the mortgage loans that are held by the trusts.  The party that is determined to have the most power to direct the loss mitigation actions that are taken with respect to delinquent or otherwise troubled mortgage loans held by the trust is, therefore, deemed to hold the most power to direct the activities that most significantly impact the trust’s economic performance.  As a passive investor, the Company does not have the power to direct the loss mitigation activities of most of the trusts that have issued its securitized mortgage assets.

Repurchase Agreements

The Company finances the purchase of mortgage investments through repurchase agreements, which are accounted for as collateralized borrowing arrangements. In a repurchase transaction, the Company sells a mortgage investment to a counterparty under a master repurchase agreement in exchange for cash and concurrently agrees to repurchase the same asset at a future date in an amount equal to the cash initially exchanged plus an agreed-upon amount of interest. Mortgage investments sold under agreements to repurchase remain on the Company’s consolidated balance sheets because the Company maintains effective control over such assets throughout the duration of the arrangement. Throughout the contractual term of a repurchase agreement, the Company recognizes a “repurchase agreement” liability on its consolidated balance sheets to reflect the obligation to repay to the counterparty the proceeds received upon the initial transfer of the mortgage investment. The difference between the proceeds received by the Company upon the initial transfer of the mortgage investment and the contractually agreed-upon repurchase price is recognized as interest expense ratably over the term of the repurchase arrangement.

Derivative Instruments

In the normal course of its operations, the Company is a party to financial instruments that are accounted for as derivative instruments. Derivative instruments are recorded at fair value as either “derivative assets” or “derivative liabilities” in the consolidated balance sheets, with all periodic changes in fair value reflected as a component of “investment gain (loss), net” in the consolidated statements of comprehensive income. Cash receipts or payments related to derivative instruments are classified as investing activities within the consolidated statements of cash flows.

In addition to interest rate hedging instruments that are used for interest rate risk management, the Company is a party to derivative instruments that economically serve as investments, such as forward commitments to purchase fixed-rate “pass-through” agency MBS on a non-specified pool basis, which are known as to-be-announced (“TBA”) securities. A TBA security is a forward commitment for the purchase or sale of a fixed-rate agency MBS at a predetermined price, face amount, issuer, coupon, and stated maturity for settlement on an agreed upon future date. The specific agency MBS that will be delivered to satisfy the TBA trade is not known at the inception of the trade. The specific agency MBS to be delivered is determined 48 hours prior to the settlement date. The Company accounts for TBA securities as derivative instruments because the Company cannot assert that it is probable at inception and throughout the term of an individual TBA commitment that its settlement will result in physical delivery of the underlying agency MBS, or the individual TBA commitment will not settle in the shortest time period possible.

Derivatives, Offsetting of Financial Assets and Liabilities

The agreements that govern certain of the Company’s derivative instruments and collateralized short-term financing arrangements provide for a right of setoff in the event of default or bankruptcy with respect to either party to such transactions. The Company presents derivative assets and liabilities as well as collateralized short-term financing arrangements on a gross basis.

Receivables recognized for the right to reclaim cash initial margin posted in respect of interest rate derivative instruments are included in the line item “deposits” in the accompanying consolidated balance sheets.

The daily exchange of variation margin associated with a centrally cleared or exchange-traded derivative instrument is legally characterized as the daily settlement of the derivative instrument itself, as opposed to a pledge of collateral. Accordingly, the Company accounts for the daily receipt or payment of variation margin associated with its interest rate swaps and futures as a direct reduction to the carrying value of derivative asset or liability, respectively. The carrying amount of interest rate swaps and futures reflected in the Company’s consolidated balance sheets is equal to the unsettled fair value of such instruments; because variation margin is exchanged on a one-day lag, the unsettled fair value of such instruments generally represents the change in fair value that occurred on the last day of the reporting period.

Fair Value of Financial Instruments

The accounting principles related to fair value measurements define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial Accounting Standards Board Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, giving the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3) as described below:

Level 1 Inputs -  Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible by the Company at the measurement date;

Level 2 Inputs -  Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and

Level 3 Inputs -  Unobservable inputs for the asset or liability, including significant judgments made by the Company about the assumptions that a market participant would use.

The Company measures the fair value of the following assets and liabilities:

Single-Family Residential Properties

Investment Security Purchases and Sales

The Company’s investments in SFR properties are initially recognized on the settlement date of their acquisition at cost.  The Company allocates the initial acquisition cost of each property to land and building on the basis of their relative fair values at the time of acquisition.  To determine the relative fair value of land and building at the time of acquisition, the Company uses available market data, such as property specific county tax assessment records.

Subsequent to the acquisition of a property, expenditures which improve or extend the life of the property are capitalized as a component of the property’s cost basis.  Expenditures for ordinary maintenance and repairs are recognized as an expense as incurred and are reported as a component of “single-family property operating expenses” in the Company’s consolidated statements of comprehensive income.

The Company subsequently recognizes depreciation of each property’s buildings and capitalized improvements over the expected useful lives of those assets.  The Company calculates depreciation on a straight-line basis over a useful life of 27.5 years for buildings and useful lives ranging from five to 27.5 years for capitalized improvements.  The Company reports depreciation expense as a component of “single-family property operating expenses” in the Company’s consolidated statements of comprehensive income.

Agency MBS

Investment Security Purchases and Sales

The Company has elected to classify its investments in agency MBS as trading securities.  Accordingly, the Company’s investments in agency MBS are reported in the accompanying consolidated balance sheets at fair value.  As of September 30, 2021 and December 31, 2020, the fair value of the Company’s investments in agency MBS was $637,718 and $970,880, respectively.

Mortgage Credit Securities

Investment Security Purchases and Sales

The Company has elected to classify its investments in mortgage credit securities as trading securities.  Accordingly, the Company’s investments in mortgage credit securities are reported in the accompanying consolidated balance sheets at fair value.  As of September 30, 2021 and December 31, 2020, the fair value of the Company’s investments in mortgage credit securities was $25,477 and $26,660, respectively.

Loans Held for Investment

Investment Security Purchases and Sales

The Company has elected to account for its loans held for investment at fair value on a recurring basis with periodic changes in fair value recognized as a component of “investment gain (loss), net” in the accompanying consolidated statements of comprehensive income.

M S R Financing Receivables

Investment Security Purchases and Sales

Under GAAP, the Company accounts for transactions executed under its arrangement as financing transactions and reflects the associated financing receivables in the line item “MSR financing receivables” on its consolidated balance sheets.  The Company has elected to account for its MSR financing receivables at fair value with changes in fair value that are not attributed to interest income recognized as a component of “investment gain (loss), net” in the accompanying consolidated statements of comprehensive income.  As described in further detail in “Note 2. Summary of Significant Accounting Policies,” the Company recognizes interest income for MSR financing receivables by applying the prospective level-yield methodology required by GAAP for financial assets that are either not of high credit quality at the time of acquisition or can be contractually prepaid or otherwise settled in such a way that the Company would not recover substantially all of its recorded investment.
