Organization and Significant Accounting Policies | NOTE 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Our Company We were incorporated in Maryland on October 20, 1997 and commenced operations on March 17, 1998. Our principal business is to invest in, finance, and manage a leveraged portfolio of residential mortgage-backed securities, or MBS, and residential mortgage loans, which presently include the following types of investments: · Agency mortgage-backed securities , or Agency MBS, which include residential mortgage pass-through certificates and collateralized mortgage obligations, or CMOs, which are securities representing interests in pools of mortgage loans secured by residential property in which the principal and interest payments are guaranteed by a government-sponsored enterprise, or GSE, such as the Federal National Mortgage Association, or Fannie Mae, or the Federal Home Loan Mortgage Corporation, or Freddie Mac. · Non-agency mortgage-backed securities , or Non-Agency MBS, which are securities issued by companies that are not guaranteed by a GSE and that are secured primarily by first-lien residential mortgage loans. · Residential mortgage loans through consolidated securitization trusts . We finance residential mortgage loans through asset-backed securities, or ABS, issued by the consolidated securitization trusts. The ABS which are held by unaffiliated third parties are non-recourse financing. The difference in the amount of the loans and the amount of the ABS represents our retained net interest in the securitization trusts. Our principal business objective is to generate net income for distribution to our stockholders primarily based upon the spread between the interest income on our mortgage assets and our borrowing costs to finance our acquisition of those assets. We have elected to be taxed as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended, or the Code. As long as we retain our REIT status, we generally will not be subject to federal or state income taxes to the extent that we distribute our taxable net income to our stockholders, and we routinely distribute to our stockholders substantially all of the taxable net income generated from our operations. In order to qualify as a REIT, we must meet various ongoing requirements under the tax law, including requirements relating to the composition of our assets, the nature of our gross income, minimum distribution requirements, and requirements relating to the ownership of our stock. Our Manager We are externally managed and advised by Anworth Management LLC, or our Manager. Effective as of December 31, 2011, we entered into a management agreement, or the Management Agreement, with our Manager, which effected the externalization of our management function, or the Externalization. Since the effective date of the Externalization, our day-to-day operations are being conducted by our Manager through the authority delegated to it under the Management Agreement and pursuant to the policies established by our board of directors, or our Board. Our Manager is supervised by our Board and is responsible for administering our day-to-day operations. In addition, our Manager is responsible for (i) the selection, purchase, and sale of our investment portfolio; (ii) our financing and hedging activities; and (iii) providing us with management services. Our Manager will also perform such other services and activities relating to our assets and operations as may be appropriate. In exchange for these services, our Manager receives a management fee, paid monthly in arrears, in an amount equal to one-twelfth of 1.20% of our Equity (as defined in the Management Agreement). BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements are prepared on the accrual basis of accounting in accordance with generally accepted accounting principles utilized in the United States of America, or GAAP. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Material estimates that are susceptible to change relate to the determination of the fair value of investments and derivatives, cash flow projections for and credit performance of Non-Agency MBS and residential mortgage loans held-for-investment, amortization of security and loan premiums, accretion of security and loan discounts, and accounting for derivative activities. Actual results could materially differ from these estimates. In the opinion of management, all material adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Our consolidated financial statements include the accounts of all subsidiaries. Significant intercompany accounts and transactions have been eliminated. The interim financial information in the accompanying unaudited consolidated financial statements and the notes thereto should be read in conjunction with the audited financial statements included in our Annual Report on Form 10‑K for the fiscal year ended December 31, 2017. Our consolidated financial statements also include the consolidation of certain securitization trusts that meet the definition of a variable interest entity, or VIEs, because the Company has been deemed to be the primary beneficiary of the securitization trusts. These securitization trusts hold pools of residential mortgage loans and issue series of ABS payable from the cash flows generated by the underlying pools of residential mortgage loans. These securitizations are non-recourse financing for the residential mortgage loans held-for-investment. Generally, a portion of the ABS issued by the securitization trusts are sold to unaffiliated third parties and the balance is purchased by the Company. The Company classifies the underlying residential mortgage loans owned by the securitization trusts as residential mortgage loans held-for-investment in its consolidated balance sheets. The ABS issued to third parties are recorded as liabilities on the Company’s consolidated balance sheets. The Company records interest income on the residential mortgage loans held-for-investment and interest expense on the ABS issued to third parties in the Company’s consolidated statements of operations. The Company records the initial underlying assets and liabilities of the consolidated securitization trusts at their fair value upon consolidation into the Company and, as such, no gain or loss is recorded upon consolidation. See Note 4, “Variable Interest Entities,” for additional information regarding the impact of consolidation of securitization trusts. The consolidated securitization trusts are VIEs because the securitization trusts do not have equity that meets the definition of GAAP equity at risk. In determining if a securitization trust should be consolidated, the Company evaluates (in accordance with the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, 810‑10) whether it has both (i) the power to direct the activities of the securitization trust that most significantly impact its economic performance and (ii) the right to receive benefits from the securitization trust or the obligation to absorb losses of the securitization trust that could be significant. The Company determined that it is the primary beneficiary of certain securitization trusts because it has certain delinquency and default oversight rights on residential mortgage loans. In addition, the Company owns the most subordinated class of ABS issued by the securitization trusts and has the obligation to absorb losses and right to receive benefits from the securitization trusts that could potentially be significant to the securitization trusts. The Company assesses modifications, if any, to VIEs on an ongoing basis to determine if a significant reconsideration event has occurred that would change the Company’s initial consolidation assessment. The following is a summary of our significant accounting policies: Revenue Recognition During the three months ended March 31, 2018, we adopted ASU 2014-09, “Revenue from Contracts with Customers,” and the other ASUs related to ASU 2014-09. These ASUs did not have a material impact on our financial statements. Our revenue streams are primarily from investments in MBS and residential mortgage loans held-for-investment. These are considered financial instruments under ASU 2014-09 and are excluded from the scope of this ASU, as they are covered under various ASC topics. A smaller portion of our business is the ownership and rental of residential properties. These residential property leases are also excluded from ASU 2014-09, as they are covered under ASC 840, “Leases.” The detail of the revenue recognition for each of our revenue streams is covered under the discussion for each of those items. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and highly liquid investments with original maturities of three months or less. The carrying amount of cash equivalents approximates their fair value. Restricted cash includes cash pledged as collateral to counterparties on various derivative transactions. Mortgage-Backed Securities Agency MBS are securities that are obligations (including principal and interest) guaranteed by federally sponsored enterprises, such as Fannie Mae or Freddie Mac. Our investment-grade Agency MBS portfolio is invested primarily in fixed-rate and adjustable-rate mortgage-backed pass-through certificates and hybrid adjustable-rate MBS. Hybrid adjustable-rate MBS have an initial interest rate that is fixed for a certain period, usually one to ten years, and then adjusts annually for the remainder of the term of the asset. We structure our investment portfolio to be diversified with a variety of prepayment characteristics, investing in mortgage assets with prepayment penalties, investing in certain mortgage security structures that have prepayment protections and purchasing mortgage assets at a premium and at a discount. A portion of our portfolio consists of Non-Agency MBS. Our principal business objective is to generate net income for distribution to our stockholders primarily based upon the spread between the interest income on our mortgage assets and our borrowing costs to finance our acquisition of those assets. We classify our MBS as trading investments, available-for-sale investments, or held-to-maturity investments. Our management determines the appropriate classification of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date. We currently classify most of our MBS as available-for-sale. We have also designated a portion of our MBS as trading investments. All assets that are classified as available-for-sale are carried at fair value and unrealized gains or losses are generally included in “Other comprehensive income (loss)” as a component of stockholders’ equity. Losses that are credit-related on securities classified as available-for-sale, which are determined by management to be other-than-temporary in nature, are reclassified from “Other comprehensive income (loss)” on the consolidated balance sheets to income (loss) on the consolidated statements of operations. Assets classified as trading investments are reported at fair value with unrealized gains and losses included in our consolidated statements of operations. The most significant source of our revenue is derived from our investments in MBS. Interest income on Agency MBS is accrued based on the actual coupon rate and the outstanding principal amount of the underlying mortgages. Premiums and discounts are amortized or accreted into interest income over the estimated lives of the securities using the effective interest yield method, adjusted for the effects of actual and estimated prepayments based on ASC 320‑10. Our policy for estimating prepayment speeds for calculating the effective yield is to evaluate historical performance, street consensus prepayment speeds and current market conditions. If our estimate of prepayments is materially incorrect, as compared to the aforementioned references, we may be required to make an adjustment to the amortization or accretion of premiums and discounts that would have an impact on future income, which could be material and adverse. A majority of our Non-Agency MBS are accounted for under “Loans and Debt Securities Acquired with Credit Deterioration” (ASC 310‑30). A debt security accounted for under ASC 310‑30 is initially recorded at its purchase price (fair value). The amount of expected cash flows that exceed the initial investment represents the market yield adjustment (accretable yield), which is recognized as interest income on a level yield basis over the life of the security. The excess of total contractual cash flows over the cash flows expected at its origination is considered to be the non-accretable difference. We must periodically reassess the expected cash flows of loans accounted for under ASC 310‑30 along with the cash flows received. A significant increase in expected cash flows must be accounted for as an increase in the rate of accretion over the remaining life of the security. Conversely, if expected cash flows decrease, an other-than-temporary impairment must be recognized as a charge to earnings. Adjustments to the fair value of Non-Agency MBS, accounted for as available-for-sale securities, are recorded in AOCI. The determination as to whether impairment and accretable yield exists is based on cash flow projections related to the securities. As a result, the timing and amount of impairment and accretable yield constitutes material estimates that are susceptible to significant change. Interest income on the Non-Agency MBS that were purchased at a discount to par value and were rated below AA at the time of purchase is recognized based on the security’s effective interest rate. The effective interest rate on these securities is based on the projected cash flows from each security, which are estimated based on our observation of current information and events and include assumptions related to interest rates, prepayment rates, and the timing and amount of credit losses. On at least a quarterly basis, we review and, if appropriate, make adjustments to our cash flow projections based on input and analysis received from external sources, internal models, and our judgment about interest rates, prepayment rates, the timing and amount of credit losses, and other factors. Changes in cash flows from those originally projected, or from those estimated at the last evaluation, may result in a prospective change in the yield/interest income recognized on such securities. Actual maturities of the available-for-sale securities are affected by the contractual lives of the associated mortgage collateral, periodic payments of principal, and prepayments of principal. Therefore actual maturities of available-for-sale securities are generally shorter than stated contractual maturities. Stated contractual maturities are generally greater than ten years. There can be no assurance that our assumptions used to estimate future cash flows or the current period’s yield for each asset would not change in the near term, and the change could be material. Based on the projected cash flows from our Non-Agency MBS purchased at a discount to par value, a portion of the purchase discount may be designated as a non-accretable difference and, therefore, not accreted into interest income. The amount designated as a non-accretable difference may be adjusted over time, based on the actual performance of the security, its underlying collateral, actual and projected cash flow from such collateral, economic conditions, and other factors. If the performance of a security with a non-accretable difference is more favorable than forecasted, a portion of the amount designated as a non-accretable difference may be accreted into interest income prospectively. Conversely, if the performance of a security with a non-accretable difference is less favorable than forecasted, an impairment charge and write-down of such security to a new cost basis results. Securities transactions are recorded on the date the securities are purchased or sold. Realized gains or losses from securities transactions are determined based on the specific identified cost of the securities. The following tables show the gross unrealized losses and fair value of those individual securities in our MBS portfolio that are in a continuous unrealized loss position at March 31, 2018 and December 31, 2017, aggregated by investment category and length of time: March 31, 2018 Less Than 12 Months 12 Months or More Total Description Number Number Number of of Fair Unrealized of Fair Unrealized of Fair Unrealized Securities Securities Value Losses Securities Value Losses Securities Value Losses (in thousands) (in thousands) (in thousands) Agency MBS 86 $ 1,124,748 $ (20,898) 175 $ 806,775 $ (24,735) 261 $ 1,931,523 $ (45,633) Non-Agency MBS 14 $ 104,787 $ (1,416) 12 $ 75,186 $ (1,963) 26 $ 179,973 $ (3,379) December 31, 2017 Less Than 12 Months 12 Months or More Total Description Number Number Number of of Fair Unrealized of Fair Unrealized of Fair Unrealized Securities Securities Value Losses Securities Value Losses Securities Value Losses (in thousands) (in thousands) (in thousands) Agency MBS 73 $ 1,171,947 $ (7,770) 192 $ 884,897 $ (17,598) 265 $ 2,056,844 $ (25,368) Non-Agency MBS 9 $ 63,568 $ (774) 14 $ 85,569 $ (2,380) 23 $ 149,137 $ (3,154) We do not consider those available-for-sale Agency MBS, or AFS MBS, that have been in a continuous loss position for 12 months or more to be other-than-temporarily impaired. The unrealized losses on our investments in AFS MBS were caused by fluctuations in interest rates. We purchased the AFS MBS primarily at a premium relative to their face value and the contractual cash flows of those investments are guaranteed by the GSEs. Since September 2008, the GSEs have been in the conservatorship of the U.S. government. At March 31, 2018, we did not expect to sell the AFS MBS at a price less than the amortized cost basis of our investments. Because the decline in market value of the AFS MBS is attributable to changes in interest rates and not the credit quality of the AFS MBS in our portfolio, and because we did not have the intent to sell these investments nor is it more likely than not that we will be required to sell these investments before recovery of their amortized cost basis, which may be at maturity, we do not consider these investments to be other-than-temporarily impaired at March 31, 2018. At March 31, 2018, there was an aggregate of approximately $19.9 million in unrealized losses on Trading Agency MBS that was not included in the table above, as this is recognized on our statements of operations. At December 31, 2017, there was an aggregate of approximately $11 million in unrealized losses on Trading Agency MBS that was not included in the table above, as they were previously recognized on our statements of operations. The unrealized losses on our investments in Non-Agency MBS were primarily caused by fluctuations in interest rates. We purchased the Non-Agency MBS primarily at a discount relative to their face value. At March 31, 2018, we did not expect to sell these Non-Agency MBS at a price less than the amortized cost basis of our investments. Because the decline in market value of these Non-Agency MBS is attributable to changes in interest rates and not the credit quality of these Non-Agency MBS in our portfolio, and because we did not have the intent to sell these investments nor is it more likely than not that we will be required to sell these investments before recovery of their amortized cost basis, which may be at maturity, we do not consider these investments to be other-than-temporarily impaired at March 31, 2018. Residential Mortgage Loans Held-for-Investment Residential mortgage loans held-for-investment are residential mortgage loans held by consolidated securitization trusts. Residential mortgage loans held-for-investment are carried at unpaid principal balances net of any premiums or discounts and allowance for loan losses. We expect that we will be required to continue to consolidate the securitization trusts that hold the residential mortgage loans. We establish an allowance for residential loan losses based on our estimate of credit losses. These estimates for the allowance for loan losses require consideration of various observable inputs including, but not limited to, historical loss experience, delinquency status, borrower credit scores, geographic concentrations, and loan-to-value ratios, and are adjusted for current economic conditions as deemed necessary by our management. Many of these factors are subjective and cannot be reduced to a mathematical formula. In addition, since we have not incurred any significant amount of direct losses on our portfolio, we review national historical credit performance information from external sources to assist in our analysis. Changes in our estimates can significantly impact the allowance for loan losses and provision expense. The allowance reflects management’s best estimate of the credit losses inherent in the loan portfolio at the balance sheet date. It is also possible that we will experience credit losses that are different from our current estimates or that the time of those losses may differ from our estimates. We recognize interest income from residential mortgage loans on an accrual basis. Any related premium or discount is amortized into interest income using the effective interest method over the weighted average life of these loans. Coupon interest is recognized as revenue when earned and deemed collectable or until a loan becomes more than 90 days past due, at which point the loan is placed on non-accrual status. Interest previously accrued for loans that have been placed on non-accrual status is reversed against interest income in the period the loan is placed in non-accrual status. Residential loans delinquent more than 90 days or in foreclosure are characterized as delinquent. Cash principal and interest that are advanced from servicers after a loan becomes greater than 90 days past due are recorded as a liability due to the servicer. When a delinquent loan previously placed on non-accrual status has cured, meaning all delinquent principal and interest have been remitted by the borrower, the loan is placed back on accrual status. Alternatively, non-accrual loans may be placed back on accrual status if restructured and after the loan is considered re-performing. A restructured loan is considered re-performing when the loan has been current for at least 12 months. Residential Properties Residential properties are stated at cost and consist of land, buildings, and improvements, including other costs incurred during their acquisition, possession, and renovation. Residential properties purchased that are not subject to an existing lease are treated as asset acquisitions and, as such, are recorded at their purchase price, including acquisition and renovation costs, all of which are allocated to land and building based upon their relative fair values at the date of acquisition. Residential properties acquired either subject to an existing lease or as part of a portfolio level transaction are treated as a business combination under ASC 805, Business Combinations , and, as such, are recorded at fair value, allocated to land, building and the existing lease, if applicable, based upon their relative fair values at the date of acquisition, with acquisition fees and other costs expensed as incurred. Building depreciation is computed on a straight-line basis over the estimated useful lives of the assets. We will generally use a 27.5 year estimated life with no salvage value. We will incur costs to prepare our acquired properties to be leased. These costs will be capitalized and allocated to building costs. Costs related to the restoration, renovation, or improvement of our properties that improve and extend their useful lives are capitalized and depreciated over their estimated useful lives. Expenditures for ordinary repairs and maintenance are expensed as incurred. Costs incurred by us to lease the properties will be capitalized and amortized over the life of the lease. Escrow deposits include refundable and non-refundable cash and earnest money on deposit with independent third parties for property purchases. Repurchase Agreements We finance the acquisition of MBS primarily through the use of repurchase agreements. Under these repurchase agreements, we sell securities to a lender and agree to repurchase the same securities in the future for a price that is higher than the original sales price. The difference between the sale price that we receive and the repurchase price that we pay represents interest paid to the lender. Although structured as a sale and repurchase obligation, a repurchase agreement operates as a financing under which we pledge our securities and accrued interest as collateral to secure a loan which is equal in value to a specified percentage of the estimated fair value of the pledged collateral. We retain beneficial ownership of the pledged collateral. Upon the maturity of a repurchase agreement, we are required to repay the loan and concurrently receive back our pledged collateral from the lender or, with the consent of the lender, we may renew such agreement at the then-prevailing financing rate. These repurchase agreements may require us to pledge additional assets to the lender in the event the estimated fair value of the existing pledged collateral declines. Asset-Backed Securities Issued by Securitization Trusts Asset-backed securities issued by the securitization trusts are recorded at principal balances net of unamortized premiums or discounts. This long-term debt is collateralized only by the assets held in the trusts and is otherwise non-recourse to the Company. Derivative Financial Instruments Risk Management We primarily use short-term (less than or equal to 12 months) repurchase agreements to finance the purchase of MBS. These obligations expose us to variability in interest payments due to changes in interest rates. We actively monitor changes in interest rate exposures and evaluate various opportunities to mitigate this risk. Our objective is to limit the impact of interest rate changes on earnings and cash flows. The principal instruments we use to achieve this are interest rate swap agreements, or interest rate swaps. Interest rate swaps effectively convert a percentage of our repurchase agreements to fixed-rate obligations over a period of up to ten years. Under interest rate swaps, we agree to pay an amount equal to a specified fixed-rate of interest times a notional principal amount and to receive in return an amount equal to a specified variable-rate of interest times a notional amount, generally based on the London Interbank Offered Rate, or LIBOR. The notional amounts are not exchanged. We do not issue nor hold the interest rate swaps for speculative purposes. We also enter into To-Be-Announced, or TBA, Agency MBS as either a means of investing in and financing Agency MBS, or as a means of disposing of or reducing our exposure to agency securities. Pursuant to TBA contracts, we agree to purchase or sell, for future delivery, Agency MBS with certain principal and interest terms and certain types of collateral, but the particular Agency MBS to be delivered are not identified until shortly before the TBA settlement date. We also may choose, prior to settlement, to move the settlement of these MBS out to a later date by entering into an offsetting short or long position (referred to as a “pair off”), net settling the paired-off positions for cash, and simultaneously purchasing a similar TBA contract for a later settlement date. This transaction is commonly referred to as a “dollar roll.” The Agency MBS purchased or sold for a forward settlement date are typically priced at a discount to agency securities for settlement in the current month. This difference (or discount) is referred to as the “price drop.” The price drop represents compensation to us for foregoing net interest margin (interest income less repurchase agreement financing cost). TBA Agency MBS are accounted for as derivative instruments since they do not meet the exemption allowed for a “regular way” security trade under ASC 815, as either the TBA contracts do not settle in the shortest period of time possible or we cannot assess that it is probable at inception that we will take physical delivery of the security or that we will not settle on a net basis. Accounting for Derivatives and Hedging Activities We account for derivative instruments in accordance with ASC 815, which requires recognition of all derivatives as either assets or liabilities and measurement of those instruments at fair value, which is typically based on values obtained from large financial institutions who are market makers for these types of instruments. The accounting for changes in the fair value of derivative instruments depends on whether the instruments are designated and qualify as hedges in accordance with ASC 815. Changes in fair value related to derivatives not designated as hedges are recorded in our consolidated statements of operations as “Gain (loss) on derivatives.” For a derivative to qualify for hedge accounting, we must anticipate that the hedge will be highly “effective” as defined by ASC 815‑10. A hedge of the variability of cash flows that are to be received or paid in connection with a recognized asset or liability is known as a ”cash flow” hedge. Changes in the fair value of a derivative that is highly effective and that is designated as a cash flow hedge, to the extent the hedge is effective, are recorded in AOCI and reclassified to income when the forecasted transaction affects income (e.g. when periodic settlement interest payments are due on repurchase agreements). Hedge ineffectiveness, if any, is recorded in current period income. When we discontinue hedge accounting, the gain or loss on the derivative remains in AOCI and is reclassified as an unrealized gain or loss on the consolidated statements of operations when the forecasted transaction affects income. In all situations where hedge accounting is discontinued and the derivative remains outstanding, we carry the derivative at its fair value on our balance sheet, recognizing changes in fair value in the current period consolidated statements of operations. All of our interest rate swaps had historically been accounted for as cash flow hedges under ASC 815. After August 22, 2014, none of our interest rate swaps were designated for hedge accounting. As a result of discontinuing hedge accounting for our interest rate swaps, changes in the fair value of these interest rate swaps are recorded in “Gain (loss) on derivatives, net” in our consolidated statements of operations rather than in AOCI. Also, net interest paid or received on these interest rate swaps which was previously recognized in interest expense, is instead recognized in “Gain (loss) on derivatives, net.” These interest rate swaps continue to be reported as assets or liabilities on our consolidated balance sheets at their fair value. As long as the forecasted transactions that were being hedged (i.e. rollovers of our repurchase agreement borrowings) are still expected to occur, the balance in AOCI from the activity in these interest rate swaps through the dates of de-designation will remain in AOCI and be recognized in our consolidated statements of operations as “interest expense” over the remaining term of these interest rate swaps. For purposes of the consolidated statements of cash flows, cash flows hedges were classified with the cash flows from the hedged item. Cash flows from derivatives that are not hedges are classified according to the underlying nature or purpose of the derivative transaction. For more details on the amounts and other qualitative information on all our derivative transactions, see Note 14. For more information on the fair value of our derivative instruments, see Note 8.
