Organization
Western Asset Mortgage Capital Corporation, is a Delaware corporation, and its subsidiaries (the "Company") commenced operations in May 2012. The Company invests in, finances and manages a diversified portfolio of real estate related securities, whole-loans and other financial assets. The Company's portfolio is comprised of Agency RMBS (including TBAs), Non-Agency RMBS, Agency and Non-Agency CMBS and Whole-Loans. In addition, and to a significantly lesser extent, the Company has invested in other securities including certain Agency obligations that are not technically MBS as well as certain Non U.S. CMBS and in asset-backed securities ("ABS") investments secured by a portfolio of private student loans. The Company's investment strategy is based on Western Asset Management Company's (the "Manager") perspective of which mix of portfolio assets it believes provides the Company with the best risk-reward opportunities at any given time. The Manager will vary the allocation among various asset classes subject to maintaining the Company's qualification as a REIT and maintaining its exemption from the Investment Company Act of 1940 (the "1940 Act"). These restrictions limit the Company's ability to invest in non-qualifying MBS, non-real estate assets and/or assets which are not secured by real estate. Accordingly, the Company's portfolio will continue to be principally invested in qualifying MBS, Whole-Loans and other real estate related assets.
The Company is externally managed by the Manager, an investment advisor registered with the Securities and Exchange Commission ("SEC"). The Manager is a wholly-owned subsidiary of Legg Mason, Inc. The Company operates and has elected to be taxed as a real estate investment trust or "REIT" commencing with its taxable year ended December 31, 2012.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies
Basis of Presentation and Consolidation
The consolidated financial statements of the Company are prepared in accordance with generally accepted accounting principles in the United States ("GAAP"). The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and variable interest entities ("VIEs") in which it is considered the primary beneficiary. Refer to Note 5—"Variable Interest Entities" for additional information regarding the impact of consolidation of theses VIE's. All intercompany amounts between the Company and its subsidiary and consolidated VIE's have been eliminated in consolidation.
Variable Interest Entities
VIEs are defined as entities that by design either lack sufficient equity for the entity to finance its activities without additional subordinated financial support or are unable to direct the entity's activities or are not exposed to the entity's losses or entitled to its residual returns. The Company evaluates all of its interests in VIEs for consolidation. When the interests are determined to be variable interests, the Company assesses whether it is deemed the primary beneficiary. The primary beneficiary of a VIE is determined to be the party that has both the power to direct the activities of a VIE that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE.
To assess whether the Company has the power to direct the activities of a VIE that most significantly impact the VIE's economic performance, it considers all facts and circumstances, including its role in establishing the VIE and its ongoing rights and responsibilities. This assessment includes first, identifying the activities that most significantly impact the VIE's economic performance; and second, identifying which party, if any, has power over those activities. In general, the parties that make the most significant decisions affecting the VIE or have the right to unilaterally remove those decision makers is deemed to have the power to direct the activities of a VIE.
To assess whether the Company has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, it considers all of its economic interests. This assessment requires the Company to apply judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Factors considered in assessing significance include: the design of the VIE, including its capitalization structure; subordination of interests; payment priority; relative share of interests held across various classes within the VIE's capital structure; and the reasons why the interests are held by the Company.
In instances when a VIE is owned by both the Company and related parties, the Company considers whether there is a single party in the related party group that meets both the power and losses or benefits criteria on its own as though no related party relationship existed. If one party within the related party group meets both these criteria, such reporting entity is the primary beneficiary of the VIE and no further analysis is needed. If no party within the related party group on its own meets both the power and losses or benefits criteria, but the related party group does as a whole meets these two criteria, the determination of primary beneficiary within the related party group is based upon an analysis of the facts and circumstances with the objective of determining which party is most closely associated with the VIE. Determining the primary beneficiary within the related party group requires significant judgment.
In instances when the Company is required to consolidate a VIE that is determined to be a qualifying collateralized financing entity, under GAAP, the Company will measure both the financial assets and financial liabilities of the VIE using the fair value of either the VIE's financial assets or financial liabilities, whichever is more observable.
Ongoing assessments of whether an enterprise is the primary beneficiary of a VIE are required.
Use of Estimates
The preparation of the consolidated financial statements 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 periods. Actual results could differ from those estimates.
Reclassification
Certain prior period amounts have been reclassified in the consolidated financial statements to conform to current period presentation.
Earnings (Loss) per share
GAAP requires use of the two-class method in computing earnings per share for all periods presented for each class of common stock and participating securities as if all earnings for the period had been distributed. Under the two-class method, during periods of net income, the net income is first reduced for dividends declared on all classes of securities to arrive at undistributed earnings. During periods of net losses, the net loss is reduced for dividends declared on participating securities only if the security has the right to participate in the earnings of the entity and an objectively determinable contractual obligation to share in net losses of the entity. The Company's participating securities are not allocated a share of the net loss, as the participating securities do not have a contractual obligation to share in the net losses of the Company.
The remaining earnings are allocated to common stockholders and participating securities, to the extent that each security shares in earnings, as if all of the earnings for the period had been distributed. Each total is then divided by the applicable number of weighted average outstanding common shares outstanding to arrive at basic earnings per share. For the diluted earnings, the denominator includes the weighted average outstanding common shares and all potential common shares assumed issued if they are dilutive. The numerator is adjusted for any changes in income or loss that would result from the assumed conversion of these potential common shares.
Offering Costs
Offering costs borne by the Company in connection with common stock offerings and private placements are reflected as a reduction of additional paid-in-capital.
Cash and Cash Equivalents
The Company considers all highly-liquid short term investments with original maturities of 90 days or less when purchased to be cash equivalents. Cash and cash equivalents are exposed to concentrations of credit risk. The Company places its cash and cash equivalents with what it believes to be high credit quality institutions. At times such investments may be in excess of the Federal Deposit Insurance Corporation insurance limit.
Valuation of Financial Instruments
The Company discloses the fair value of its financial instruments according to a fair value hierarchy (Levels I, II, and III, as defined below). ASC 820 "Fair Value Measurements and Disclosures" establishes a framework for measuring fair value and expands financial statement disclosure requirements for fair value measurements. ASC 820 further specifies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation technique are observable or unobservable. The hierarchy is as follows:
Level I—Quoted prices in active markets for identical assets or liabilities.
Level II—Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
Level III—Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable, for example, when there is little or no market activity for an investment at the end of the period, unobservable inputs may be used.
The level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Transfers between levels are determined by the Company at the end of the reporting period. See Note 3 Fair Value of Financial Instruments.
Mortgage-Backed Securities and Other Securities
The Company's mortgage-backed securities and other securities portfolio primarily consists of Agency RMBS, Non-Agency RMBS, Agency CMBS and Non-Agency CMBS, ABS and other real estate related assets, these investments are recorded in accordance with ASC 320, “Investments – Debt and Equity Securities”, ASC 325-40, “Beneficial Interests in Securitized Financial Assets” or ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality”. The Company has chosen to make a fair value election pursuant to ASC 825, “Financial Instruments” for its mortgage-backed securities and other securities portfolio. Electing the fair value option allows the Company to record changes in fair value in the Consolidated Statements of Operations as a component of “Unrealized gain (loss), net”.
When the Company purchases securities with evidence of credit deterioration since origination, it will analyze to determine if the guidance found in ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality” is applicable.
The Company accounts for its securities under ASC 310 and ASC 325 and evaluates securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis. The determination of whether a security is other-than-temporarily impaired involves judgments and assumptions based on subjective and objective factors. When the fair value of an investment security is less than its amortized cost at the balance sheet date, the security is considered impaired, and the impairment is designated as either “temporary” or “other-than-temporary.” When a security is impaired, an OTTI is considered to have occurred if (i) the Company intends to sell the security (i.e., a decision has been made as of the reporting date) or (ii) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell the security or if it is more likely than not that the Company will be required to sell the real estate security before recovery of its amortized cost basis, the entire amount of the impairment loss, if any, is recognized in earnings as OTTI and the cost basis of the security is adjusted to its fair value. Additionally for securities accounted for under ASC 325-40 an OTTI is deemed to have occurred when there is an adverse change in the expected cash flows to be received and the fair value of the security is less than its carrying amount. In determining whether an adverse change in cash flows occurred, the present value of the remaining cash flows, as estimated at the initial transaction date (or the last date previously revised), is compared to the present value of the expected cash flows at the current reporting date. The estimated cash flows reflect those a “market participant” would use and are discounted at a rate equal to the current yield used to accrete interest income. Any resulting OTTI adjustments are reflected in the “Other than temporary impairment” line item in the Consolidated Statements of Operations.
The determination as to whether an OTTI exists is subjective, given that such determination is based on information available at the time of assessment as well as the Company’s estimate of the future performance and cash flow projections for the individual security. As a result, the timing and amount of an OTTI constitutes an accounting estimate that may change materially over time.

Increases in interest income may be recognized on a security on which the Company previously recorded an OTTI charge if the cash flow of such security subsequently improves.

Securities in an unrealized loss position on December 31, 2016, are not considered other than temporarily impaired if the Company had the ability and intent to hold the securities to maturity or for a period of time sufficient for a forecasted market price recovery up to or above the amortized cost of the investment, and the Company was not required to sell the security for regulatory or other reasons.

In addition, unrealized losses on the Company's Agency securities, with explicit guarantee of principal and interest by the governmental sponsored entity ("GSE"), are not credit losses but rather were due to changes in interest rates and prepayment expectations. These securities would not be considered other than temporarily impaired provided we did not intend to sell the security.
Residential Whole-Loans
Investments in Whole-Loans are recorded in accordance with ASC 310-20, "Nonrefundable Fees and Other Costs". The Company has chosen to make the fair value election pursuant to ASC 825 for its Whole-Loan portfolio. Whole-Loans are recorded at fair value in the Consolidated Balance Sheets with the periodic change in fair value being recorded in earnings in the Consolidated Statements of Operations as a component of "Unrealized gain (loss), net". All other costs incurred in connection with acquiring Whole-Loans or committing to purchase these loans are charged to expense as incurred.
The Company amortizes or accretes any premium or discount over the life of the related loan utilizing the effective interest method, based on the contractual payment terms of the loan. On at least a quarterly basis, the Company evaluates the collectability of both interest and principal of each loan, if circumstances warrant, to determine whether such loan is impaired. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the existing contractual terms. When a loan is impaired, the Company does not record an allowance for loan loss as the Company has elected the fair value option. However, income recognition is suspended for loans at the earlier of the date at which payments become 90-days past due or when, in the opinion of management, a full recovery of income and principal becomes doubtful. When the ultimate collectability of the principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. When the ultimate collectability of the principal of an impaired loan is not in doubt, contractual interest is recorded as interest income when received, under the cash basis method until an accrual is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. A loan is written off when it is no longer realizable and/or legally discharged.
Interest income recognition
Agency MBS, Non-Agency MBS and other securities, excluding Interest-Only Strips, rated AA and higher at the time of purchase
Interest income on mortgage-backed and other securities is accrued based on the respective outstanding principal balances and corresponding contractual terms. The Company records interest income in accordance with ASC subtopic 835-30 "Imputation of Interest", using the effective interest method. As such premiums and discounts associated with Agency MBS, Non-Agency MBS and other securities, excluding Interest-Only Strips, rated AA and higher at the time of purchase, are amortized into interest income over the estimated life of such securities. Adjustments to premium and discount amortization are made for actual prepayment activity. The Company estimates prepayments at least quarterly for its securities and, as a result, if the projected prepayment speed increases, the Company will accelerate the rate of amortization on premiums or discounts and make a retrospective adjustment to historical amortization. Alternatively, if projected prepayment speeds decrease, the Company will reduce the rate of amortization on the premiums or discounts and make a retrospective adjustment to historical amortization.
Non-Agency MBS and other securities that are rated below AA at the time of purchase and Interest-Only Strips that are not classified as derivatives
Interest income on Non-Agency MBS and other securities that are rated below AA at the time of purchase and Interest-Only Strips that are not classified as derivatives are also recognized in accordance with ASC 835, using the effective yield method. The effective yield on these securities is based on the projected cash flows from each security, which is estimated based on the Company's observation of the then current information and events, where applicable, and will include assumptions related to interest rates, prepayment rates and the timing and amount of credit losses. On at least a quarterly basis, the Company reviews and, if appropriate, makes adjustments to its cash flow projections based on input and analysis received from external sources, internal models, and its judgment about interest rates, prepayment rates, the timing and amount of credit losses, and other factors. Where appropriate, the Company may include in its cash flow projections the U.S. Department of Justice's settlements with the major residential mortgage originators, regarding certain lending practices. 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 securities are affected by the contractual lives of the underlying collateral, periodic payments of scheduled principal, and prepayments of principal. Therefore, actual maturities of the securities will generally be shorter than stated contractual maturities.
Based on the projected cash flow of such securities purchased at a discount to par value, the Company may designate a portion of such purchase discount as credit protection against future credit losses and, therefore, not accrete such amount into interest income. The amount designated as credit discount 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 credit discount is more favorable than forecasted, a portion of the amount designated as credit discount may be accreted into interest income prospectively.
Residential Whole-Loans
Interest income on the Company's Whole-Loan portfolio is recorded in accordance with ASC 835 using the effective interest method. Any amortization or accretion will be reflected as a component of "Interest income" in the Consolidated Statements of Operations.
Purchases and Sales of Investments
The Company accounts for a contract for the purchase or sale of securities, or other securities that do not yet exist on a trade date basis, which it intends to take possession and thus recognizes the acquisition or disposition of the securities at the inception of the contract.
Sales of investments are driven by the Company's portfolio management process. The Company seeks to mitigate risks including those associated with prepayments and will opportunistically rotate the portfolio into securities and/or other investments the Company's Manager believes have more favorable attributes. Strategies may also be employed to manage net capital gains, which need to be distributed for tax purposes. Realized gains or losses on sales of investments, including Agency Interest-Only Strips not characterized as derivatives, are a component of "Realized gain (loss) on sale of investments, net" in the Consolidated Statements of Operations, and are recorded at the time of disposition. Realized gains losses on Interest-Only Strips which are characterized as derivatives are a component of "Gain (loss) on derivative instruments, net" in the Consolidated Statements of Operations.
Foreign currency transactions
The Company has and expects to continue to enter into transactions denominated in foreign currency from time to time. At the date the transaction is recognized, the asset and/or liability will be measured and recorded using the exchange rate in effect at the date of the transaction. At each balance sheet date, such foreign currency assets and liabilities are re-measured using the exchange rate in effect at the date of the balance sheet, resulting in unrealized foreign currency gains or losses, which are recorded in "Other, net" in the Consolidated Statement of Operations.
Due from counterparties/Due to counterparties
Due from counterparties represents cash posted by the Company with its counterparties as collateral for the Company's interest rate and/or currency derivative financial instruments, repurchase agreements, and TBAs. Due to counterparties represents cash posted with the Company by its counterparties as collateral under the Company's interest rate and/or currency derivative financial instruments, repurchase agreements, and TBAs. Included in the due from counterparties and/or due to counterparties are daily variation margin settlement amounts with counterparties which are based on the price movement of the Company's futures contracts. In addition, as provided below, Due to counterparties may include non-cash collateral in which the Company has the obligation to return and which the Company has either sold or pledged. To the extent the Company receives collateral other than cash from its counterparties such assets are not included in the Company's Consolidated Balance Sheets. Notwithstanding the foregoing, if the Company either rehypothecates such assets or pledges the assets as collateral pursuant to a repurchase agreement, the cash received and the corresponding liability are reflected in the Consolidated Balance Sheets.
Derivatives and hedging activities
Subject to maintaining its qualification as a REIT for U.S. federal income tax purposes, the Company utilizes derivative financial instruments, including interest rate swaps, interest rate swaptions, mortgage put options, currency forwards, futures contracts, TBAs and Agency and Non-Agency Interest-Only Strips to hedge the interest rate and currency risk associated with its portfolio and related borrowings. Derivatives, subject to REIT requirements, are used for hedging purposes rather than speculation. The Company has also entered into a total return swap, which transfers the total return of the referenced security to the Company. The Company determines the fair value of its derivative positions and obtains quotations from third parties, including the Chicago Mercantile Exchange or CME, to facilitate the process of determining such fair values. If the Company's hedging activities do not achieve the desired results, reported earnings may be adversely affected.
GAAP requires an entity to recognize all derivatives as either assets or liabilities on the balance sheet and to measure those instruments at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative. The fair value adjustment will affect either other comprehensive income in stockholders' equity until the hedged item is recognized in earnings or net income depending on whether the derivative instrument is designated and qualifies as a for hedge for accounting purposes and if so, the nature of the hedging activity. The Company elected not to apply hedge accounting for its derivative instruments. Accordingly, the Company records the change in fair value, of its derivative instruments, which includes net interest rate swap payments (including accrued amounts) and net currency payments/receipts (including accrued amounts) related to interest rate swaps and currency swaps, respectively in "Gain (loss) on derivative instruments, net" in its Consolidated Statements of Operations.
In the Company's Consolidated Statements of Cash Flows, premiums received or paid on termination of its interest rate swaps, excluding interest rate swaps containing an other-than-insignificant financing element and the unamortized premium of market agreed coupon ("MAC") interest rate swaps, are included in cash flows from operating activities. Notwithstanding the foregoing, proceeds and payments on settlement of swaptions, mortgage put options, futures contracts and TBAs are included in cash flows from investing activities. Proceeds and payments on settlement of forward contracts are reflected in cash flows from financing activities in the Company's Consolidated Statement of Cash Flows. While payments made at the time of entering MAC interest rate swaps are included in cash flows from investing activities, payments received by the Company upon entering MAC interest rate swaps are included in either cash flows from investing activities or cash flows from financing activities, depending on whether or not the derivative instrument includes an other-than-insignificant financing element. For MAC interest rate swaps containing an other-than-insignificant financing element, all cash flows over the life of the derivative are treated as cash flows from financing activities. Return and recovery of basis activity for MAC interest rate swaps is included in cash flows from investing activities for swaps not containing an other-than-insignificant financing element in the Company's Consolidated Statements of Cash Flows. For Agency and Non-Agency Interest-Only Strips accounted for as derivatives, the purchase, sale and recovery of basis activity is included with MBS and other securities under cash flows from investing activities in the Company's Consolidated Statements of Cash Flows.
The Company evaluates the terms and conditions of its holdings of Agency and Non-Agency Interest-Only Strips, interest rate swaptions, currency forwards, futures contracts and TBAs to determine if these instruments have the characteristics of an investment or should be considered a derivative under GAAP. In determining the classification of its holdings of Interest-Only Strips, the Company evaluates the securities to determine if the nature of the cash flows has been altered from that of the underlying mortgage collateral. Interest-Only Strips, for which the underlying mortgage collateral has been included into a structured security that alters the cash flows from the underlying mortgage collateral, are accounted for as derivatives. The carrying value of the Agency and Non-Agency Interest-Only Strips, accounted for as derivatives, is included in "Mortgage-backed securities and other securities, at fair value" in the Consolidated Balance Sheets. The carrying value of interest rate swaptions, currency forwards, futures contracts and TBAs is included in "Derivative assets, at fair value" or "Derivative liability, at fair value" in the Consolidated Balance Sheets. Interest earned or paid along with the change in fair value of these instruments accounted for as derivatives is recorded in "Gain (loss) on derivative instruments, net" in its Consolidated Statements of Operations
The Company evaluates all of its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. An embedded derivative is separated from the host contact and accounted for separately when all of the guidance criteria are met. Hybrid instruments that are remeasured at fair value through earnings, including the fair value option are not bifurcated. Derivative instruments, including derivative instruments accounted for as liabilities, are recorded at fair value and are re-valued at each reporting date, with changes in the fair value together with interest earned or paid (including accrued amounts) reported in "Gain (loss) on derivative instruments, net" in the Consolidated Statements of Operations.
Repurchase agreements and Reverse Repurchase agreements
Investments sold under repurchase agreements are treated as collateralized financing transactions, unless they meet sales treatment. Securities financed through a repurchase agreement remain in the Company's Consolidated Balance Sheets as assets and cash received from the lender is recorded in the Company's Consolidated Balance Sheets as a liability. Interest payable in accordance with repurchase agreements is recorded as "Accrued interest payable" in the Consolidated Balance Sheets. Interest paid (including accrued amounts) in accordance with repurchase agreements was recorded as interest expense.
The Company may borrow securities under reverse repurchase agreements to deliver a security owned and sold by the Company but pledged to a different counterparty under a separate repurchase agreement when in the Manager's view terminating the outstanding repurchase agreement is not in the Company's best interest. Cash paid to the borrower is recorded in the Company's Consolidated Balance Sheets as an asset. Interest receivable in accordance with reverse repurchase agreements is recorded as accrued interest receivable in the Consolidated Balance Sheets. The Company reflects all proceeds on reverse repurchase agreement and repayment of reverse repurchase agreement, on a net basis in the Consolidated Statements of Cash Flows. Upon sale of a pledged security, the Company recognizes an obligation to return the borrowed security in the Consolidated Balance Sheet in "Due to counterparties". The Company establishes haircuts to ensure the market value of the underlying asset remains sufficient to protect the Company in the event of default by the counterparty. Realized gains and losses associated with the sale of the security are recognized in "Realized gain (loss) on sale of investments, net" in the Consolidated Statement of Cash Flows.
Securitized debt
Securitized debt was issued at par by a consolidated securitization trust. The Company has chosen to make the fair value election pursuant to ASC 825 for the debt. The debt is recorded at fair value in the Consolidated Balance Sheets with the periodic change in fair value recorded in current period earnings in the Consolidated Statements of Operations as a component of "Unrealized gain (loss), net".
Share-based compensation
The Company accounts for share-based compensation to its independent directors, to any employee, to its Manager and to employees of its Manager and its affiliates using the fair value based methodology prescribed by GAAP. Compensation cost related to restricted common stock issued to the Company's independent directors and any employee of the Company including any such restricted stock which is subject to a deferred compensation program, and any employee of the Company is measured at its fair value at the grant date, and amortized into expense over the service period on a straight-line basis. Compensation cost related to restricted common stock issued to the Manager and to employees of the Manager, including officers and certain directors, of the Company who are employees of the Manager and its affiliates is initially measured at fair value at the grant date, and amortized into expense over the vesting period on a straight-line basis and re-measured on subsequent dates to the extent the awards are unvested.
Warrants
For the Company's warrants, the Company uses a variation of the adjusted Black-Scholes option valuation model to record the financial instruments at their relative fair values at issuance. The warrants issued with the Company's common stock in the private placement to certain accredited institutional investors on May 15, 2012, were evaluated by the Company and were recorded at their relative fair value as a component of equity at the date of issuance.
Income taxes
The Company operates and has elected to be taxed as a REIT commencing with its taxable year ended December 31, 2012. Accordingly, the Company will generally not be subject to corporate U.S. federal or state income tax to the extent that the Company makes qualifying distributions to stockholders, and provided that the Company satisfies, on a continuing basis, through actual investment and operating results, the REIT requirements including certain asset, income, distribution and stock ownership tests. If the Company fails to qualify as a REIT, and does not qualify for certain statutory relief provisions, the Company will be subject to U.S. federal, state and local income taxes and may be precluded from qualifying as a REIT for the subsequent four taxable years following the year in which the Company lost its REIT qualification. Accordingly, the failure to qualify as a REIT could have a material adverse impact in the Company's results of operations and amounts available for distribution to stockholders.
The dividends paid deduction for qualifying dividends paid to stockholders is computed using the Company's taxable income as opposed to net income reported in the Consolidated Statements of Operations. Taxable income, generally, will differ from net income reported in the Consolidated Statements of Operations because the determination of taxable income is based on tax regulations and not GAAP.
The Company may create and elect to treat certain subsidiaries as Taxable REIT Subsidiaries ("TRS"). 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. A domestic TRS is subject to U.S. federal, state and local corporate income taxes, and for 2016 its value may not exceed 25% of the value of the Company; however, commencing in taxable year 2018 its value may not exceed 20% of the value of the Company. If the TRS generates net income it may declare dividends to the Company, which will be included in the Company's taxable income and necessitate a distribution to its stockholders. Conversely, if the Company retains earnings at the TRS level, no distribution is required and it can increase book equity of the consolidated entity. As of December 31, 2016, the Company has a single wholly-owned subsidiary which it has elected to treat as a domestic TRS.
Current and deferred taxes are recorded on earnings (losses) recognized by the Company's TRS. Deferred income tax assets and liabilities are calculated based upon temporary differences between the Company's U.S. GAAP consolidated financial statements and the federal and state basis of assets and liabilities as of the Consolidated Balance Sheets date. The Company evaluates the realizability of its deferred tax assets and recognizes a valuation allowance if, based on available evidence, it is more likely than not that some or all of its deferred tax assets will not be realized. In evaluating the realizability of the deferred tax asset, the Company will consider the expected future taxable income, existing and projected book to tax differences as well as tax planning strategies. This analysis is inherently subjective, as it is based on forecasted earning and business and economic activity. Changes in estimates of deferred tax asset realizability, if any, are included in "Income tax provision (benefit)" in the Consolidated Statements of Operations.

As a REIT, if the Company fails to distribute in any calendar year (subject to specific timing rules for certain dividends paid in January) at least the sum of (i) 85% of its ordinary income for such year, (ii) 95% of its capital gain net income for such year, and (iii) any undistributed taxable income from the prior year, the Company would be subject to a non-deductible 4% excise tax on the excess of such required distribution over the sum of (i) the amounts actually distributed and (ii) the amounts of income retained and on which the Company has paid corporate income tax.
Accounting standards applicable to emerging growth companies
The JOBS Act contains provisions that relax certain requirements for "emerging growth companies", which includes the Company. For as long as the Company is an emerging growth company, which may be up to five full fiscal years, unlike other public companies, the Company will not be required to: (i) comply with any new or revised financial accounting standards applicable to public companies until such standards are also applicable to private companies under Section 102(b)(1) of the JOBS Act; (ii) provide an auditor's attestation report on management's assessment of the effectiveness of the Company's system of internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act; (iii) comply with any new requirements adopted by the PCAOB requiring mandatory audit firm rotation or a supplement to the auditor's report in which the auditor would be required to provide additional information about the audit and the financial statements of the issuer; or (iv) comply with any new audit rules adopted by the PCAOB after April 5, 2012, unless the SEC determines otherwise. The Company currently takes advantage of some of these exemptions. The Company's qualification for remaining an emerging growth company under the five full fiscal years expires on December 31, 2017. However, the Company will no longer qualify for such exemption if its gross revenue for any year equals or exceeds $1.0 billion, the Company issues more than $1.0 billion in non-convertible debt during the three previous years, or if the Company is deemed to be a large accelerated filer.
Recent accounting pronouncements
Accounting Standards Adopted in 2016
In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements — Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” The guidance requires an entity’s management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. According to the new guidance, substantial doubt exists when conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date the financial statements are issued. The term “probable” is used consistently with its current use in U.S. GAAP for loss contingencies. Disclosures will be required if conditions give rise to substantial doubt about the entity’s ability to continue as a going concern, including whether management’s plans that are intended to mitigate those conditions will alleviate the substantial doubt when implemented. The guidance is effective for annual periods ending after December 15, 2016. The effective date is the same for both public companies and all other entities.  The 2016 adoption of the new guidance did not have a material impact on the Company’s consolidated financial statements.
 
In January 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-1, “Income Statement - Extraordinary and Unusual Items.” The guidance simplifies income statement presentation by eliminating the concept of extraordinary items. U.S. GAAP currently requires that a company separately classify, disclose and present extraordinary events and transactions. The guidance eliminates the concept of extraordinary items from U.S. GAAP.  Under the existing guidance, an entity is required to separately disclose extraordinary items, net of tax, in the income statement after income from continuing operations if an event or transaction is of an unusual nature and occurs infrequently. This separate, net-of-tax presentation (and corresponding earnings per share impact) will no longer be allowed. The existing requirement to separately present items that are of an unusual nature or occur infrequently on a pre-tax basis within income from continuing operations has been retained. The new guidance also requires similar separate presentation of items that are both unusual and infrequent. The standard is effective for periods beginning after December 15, 2015. The effective date is the same for both public companies and all other entities.  The 2016 adoption of the new guidance did not have a material impact on the Company’s consolidated financial statements.
 
In February 2015, the FASB issued ASU 2015-2, “Consolidation - Amendments to the Consolidation Analysis.” The guidance simplifies and reduces the number of consolidation models through the elimination of an indefinite deferral for certain entities and by placing more emphasis on risk of loss when determining a controlling financial interest.  The guidance affects reporting entities that are required to evaluate whether they should consolidate certain legal entities.  All legal entities are subject to reevaluation under the revised consolidation model.  The standard is effective for a public company for fiscal years, and for interim periods within fiscal years beginning after December 15, 2015.  The 2016 adoption of the new guidance did not have a material impact on the Company’s consolidated financial statements.

In April 2015, the FASB issued ASU 2015-3, “Interest - Imputation of Interest - Simplifying the Presentation of Debt Issuance Costs.” The guidance amends the presentation of debt issuance cost related to a recognized debt liability. Under the new guidance, the debt issuance costs were presented in the balance sheet as a direct deduction from the carrying amount of the recognized debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected under the new guidance. The standard is effective for a public company for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The guidance should be applied on a retrospective basis. The Company’s December 31, 2015 balance sheet was adjusted to reflect the effects of applying the new guidance on a retrospective basis and resulted in a $134 thousand reduction in Borrowings under repurchase agreements and a corresponding reduction in Other assets. Upon adoption, an entity is required to comply with the applicable disclosures for a change in an accounting principle. These disclosures include the nature of and reason for the change in accounting principle, the transition method, a description of the prior-period information that has been retrospectively adjusted, and the effect of the change on the financial statement line items (i.e., debt issuance cost asset and the debt liability). The 2016 adoption of the new guidance did not have a material impact on the Company’s consolidated financial statements.
Accounting Standards to be Adopted in Future Periods
In May 2014, the FASB issued ASU 2014-9, “Revenue from Contracts with Customers (Topic 606).” The guidance changes an entity’s recognition of revenue from contracts with customers.  The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  In addition, the new guidance requires improved disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. In March 2016, the FASB issued implementation guidance which clarifies principal versus agent considerations in reporting revenue gross versus net (ASU 2016-8). In April 2016, the FASB issued implementation guidance which clarifies the identification of performance obligations (ASU 2016-10). In May 2016, the FASB issued amendments that affect only the narrow aspects of Topic 606 (ASU2016-12). In applying the new guidance, an entity may use either a retrospective approach to each prior reporting period or a retrospective approach with the cumulative effect recognized at the date of initial application. For a public company, the standard is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is not permitted for a public entity. The Company is evaluating the new guidance and does not expect it to have a material impact on the Company’s consolidated financial statements. The Company has not yet determined the method by which it will adopt the standard in 2017.
 
In January 2016, the FASB issued ASU 2016-1, “Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The guidance improves certain aspects of recognition, measurement, presentation, and disclosure of financial instruments.  The standard is effective for a public company for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years.   The Company is currently assessing the impact that this guidance will have on its consolidated financial statements when adopted. It will apply the guidance by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption.  The guidance related to equity securities without readily determinable fair values will be applied prospectively to equity investments that exist at the date of adoption. 

In March 2016, the FASB issued ASU 2016-9, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The guidance changes the accounting for certain aspects of share-based payments to employees. The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis.  For a public company, the standard is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period.   The Company does not have direct employees and is externally managed; therefore, the adoption of this guidance will not have a material impact on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The guidance requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected by deducting an allowance for credit losses from the amortized cost basis of the financial assets. For available-for-sale debt securities, the new guidance aligns the income statement recognition of credit losses with the reporting period in which changes occur by recording credit losses through an allowance rather than a write-down and allowing subsequent reversals in credit loss estimates to be recognized in current income. The measurement of expected credit losses will be based on historical experience, current conditions and reasonable and supportable forecasts. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. For a public company, the standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption will be permitted for fiscal years beginning after December 15, 2018. The guidance should be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. For certain assets, a prospective transition approach is required. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements when adopted.

In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments (Topic 230)." The guidance is intended to reduce diversity in practice in how certain transactions are classified on the statement of cash flows. The Company is required to adopt the new guidance in the first quarter of 2018. Early adoption is permitted, provided that all of the amendments are adopted at the same time. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements when adopted.
 
 In November 2016, FASB issued ASU 2016-18 "Statement of Cash Flows (Topic 230): Restricted Cash, a consensus of the FASB's Emerging Issues Task Force." The guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents as well as disclose information about the nature of the restrictions on its cash and cash equivalents. For public business entities, the guidance is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The guidance should be applied using a retrospective transition method to each period presented. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements when adopted.

When available, the Company uses quoted market prices to determine the fair value of an asset or liability. If quoted market prices are not available, the Company will use independent pricing services and if the independent pricing service cannot price a particular asset or liability, the Company will obtain third party broker quotes. The Manager's pricing group, which functions independently from its portfolio management personnel, reviews the third party broker quotes by comparing the broker quotes for reasonableness to alternate sources when available. If independent pricing service, or third party broker quotes are not available, the Company determines the fair value of the securities using valuation techniques that use, when possible, current market-based or independently-sourced market parameters, such as interest rates and when applicable, estimates of prepayments and credit losses.
Mortgage-backed securities and other securities
In determining the proper fair value hierarchy or level, all securities are initially classified in Level III. The Company further determined, given the amount of available observable market data, Agency RMBS should be classified in Level II. For Non-Agency RMBS, CMBS and other securities, to determine whether a security should be a Level II, the securities are grouped by security type and the Manager reviews the internal trade history, for the quarter, for each security type. If there is sufficient trade data above a predetermined threshold of a security type, the Manager determines it has sufficient observable market data and the security will be categorized as a Level II.
Values for the Company's securities are based upon prices obtained from independent third party pricing services. The valuation methodology of the third party pricing services incorporates a commonly used market pricing method. Depending on the type of asset and the underlying collateral, the primary inputs to the model include yields for TBAs, Agency RMBS, the U.S. Treasury market and floating rate indices such as LIBOR, the Constant Maturity Treasury rate and the prime rate as a benchmark yield. In addition, the model may incorporate the current weighted average maturity and additional pool level information such as prepayment speeds, default frequencies and default severities, if applicable. When the third party pricing service cannot adequately price a particular security, the Company utilizes a broker's quote which is reviewed for reasonableness by the Manager's pricing group.
Residential Whole-Loans
Values for the Company's residential whole-loans are based upon prices obtained from an independent third party pricing service that specializes in whole-loans, utilizing a trade based valuation model. Their valuation methodology incorporates commonly used market pricing methods, including loan to value ("LTV"), debt to income, maturity, interest rates, collateral location, and unpaid principal balance, prepayment penalties, FICO scores, lien position and times late. Due to the inherent uncertainty of such valuation, the fair values established for residential loans held by the Company may differ from the fair values that would have been established if a readily available market existed for these loans. Accordingly, the Company's loans are classified as Level III.
Securitized commercial loan and securitized debt
Values for the Company's securitized commercial loan and securitized debt are based on which fair value is more observable. Since there is an extremely limited market for the securitized commercial loan, the Company determined the fair value of the securitized debt was more observable. The fair value of the securitized debt was based upon a third party broker quote, which is validated by the Manager's pricing group. Due to the inherent uncertainty of such valuation the Company classifies its securitized commercial loan and securitized debt as Level III.
Derivatives
Values for the Company's derivatives are based upon prices from third party pricing services, whose pricing is subject to review by the Manager's pricing committee. In valuing its over-the-counter interest rate derivatives, such as swaps and swaptions, and its currency derivatives, such as swaps and forwards and credit derivatives such as total return swaps, the Company considers the creditworthiness of both the Company and its counterparties, along with collateral provisions contained in each derivative agreement, from the perspective of both the Company and its counterparties. The majority of the Company's interest rate swaps are cleared through a central clearing house and subject to the clearing house margin requirements. The Company's agreements with its derivative counterparties also contain netting provisions; however the Company has elected to report its interest rate swaps and swaptions and currency swaps and forwards on a gross basis. No credit valuation adjustment was made in determining the fair value of interest rate and/or currency derivatives for the years ended December 31, 2016 and December 31, 2015.
The Company performs quarterly reviews of the independent third party pricing data. These reviews may consist of a review of the daily change in the prices provided by the independent pricing vendor which exceed established tolerances or comparisons to executed transaction prices, utilizing the Manager's pricing group. The Manager's pricing group, which functions independently from its portfolio management personnel, reviews the price differences or changes in price by comparing the vendor price to alternate sources including other independent pricing services or broker quotations. If the price change or difference cannot be corroborated, the Manager's pricing group consults with the portfolio management team for market color in reviewing such pricing data as warranted. To the extent that the Manager has information, typically in the form of broker quotations that would indicate that a price received from the independent pricing service is outside of a tolerance range, the Manager generally challenges the independent pricing service price.
The following tables present additional information about the Company's financial instruments which are measured at fair value on a recurring basis for which the Company has utilized Level III inputs to determine fair value:

For Mortgage-backed securities and other securities and Residential Whole-Loans classified as Level III at December 31, 2015, the Company recorded gross unrealized gains of approximately $7.3 million and $3.6 million and gross unrealized losses of approximately $13.4 million and $8 thousand, respectively. These gains and losses are included in "Unrealized gain (loss), net" in the Consolidated Statements of Operations.
Transfers between hierarchy levels during operations for the years ended December 31, 2016 and December 31, 2015 were based on the availability of sufficient observable inputs to meet Level II versus Level III criteria. The leveling of these assets was based on information received from a third party pricing service which, along with the back-testing of historical sales transactions performed by the Manager provided the sufficient observable data for the movement from Level III to Level II. The Company did not have transfers between Level I and Level II for the years ended December 31, 2016 and December 31, 2015.
Other Fair Value Disclosures
"Due from counterparties" and "Due to counterparties" in the Company's Consolidated Balance Sheets are reflected at cost which approximates fair value.
The fair value of the repurchase agreements is based on a net present value technique. This method discounts future estimated cash flows using rates the Company determined best estimates current market interest rates that would be offered for loans with similar characteristics and credit quality. The use of different market assumptions or estimation methodologies could have a material effect on the fair value amounts. At December 31, 2016, the Company's borrowings under repurchase agreements had a carrying value of approximately $2.2 billion which approximates its fair value. Inputs used to arrive at the fair value of the repurchase agreement borrowings and receivables under reverse repurchase agreements are generally observable, and therefore, they would be considered a Level II fair value measurement.

(1)
Together with coupon interest, accretable purchase discount and amortizable premium is recognized as interest income over the life of the security.
(2)
Resulting from the implementation of guidance issued by the FASB which eliminated the requirement to account for certain financial instruments as linked transactions.
(3)
Subsequent reductions of a security's non-accretable discount results in a corresponding reduction in its amortizable premium.

The Company identified 18 securities with an unpaid principal balance of $143.1 million which it intends to sell that were in an unrealized loss position at December 31, 2016, and as a result, the Company recognized an impairment charge of approximately $4.4 million on Agency RMBS which is included in "Other than temporary impairment".
The Company assesses its Agency MBS, Non-Agency MBS and other securities, excluding Interest-Only Strips, rated AA and higher at the time of purchase for other-than-temporary impairment on at least a quarterly basis. When the fair value of an investment is less than its amortized cost at the balance sheet date of the reporting period for which impairment is assessed, the impairment is designated as either "temporary" or "other-than-temporary." In deciding on whether or not a security is other-than-temporarily impaired, the Company considers several factors, including the nature of the investment, communications (if any) from the securitization trustee regarding the credit quality of the security, the severity and duration of the impairment, the cause of the impairment, and the Company's intent not to sell the security and that it is more likely than not that the Company will not be required to sell the security until recovery of its amortized cost. In addition, an other-than-temporary impairment is deemed to have occurred when there is an adverse change in the expected cash flows (principal or interest) to be received and the fair value of the security is less than its carrying amount. In determining whether an adverse change in cash flows occurred, the present value of the remaining cash flows, as estimated at the initial transaction date (or the last date previously revised), is compared to the present value of the expected cash flows at the current reporting date. The estimated cash flows reflect those a "market participant" would use and are discounted at a rate equal to the current yield used to accrete interest income. These adjustments are reflected in the Company's Consolidated Statements of Operations as "Other than temporary impairment".
For Non-Agency MBS and other securities rated below AA at the time of purchase and Agency and Non-Agency Interest-Only Strips, excluding Interest-Only Strips classified as derivatives, an other-than-temporary impairment is deemed to have occurred when there is an adverse change in the expected cash flows (principal or interest) to be received and the fair value of the beneficial interest is less than its carrying amount. Other than for "plain-vanilla" variable rate Non-Agency MBS, the Company does not bifurcate the loss between credit loss and loss attributed to change in interest rates, therefore, the entire loss is recorded as other-than-temporary. These adjustments are reflected in the Company's Consolidated Statements of Operations as "Other than temporary impairment". In determining whether an adverse change in cash flows occurred, the present value of the remaining cash flows, as estimated at the initial transaction date (or the last date previously revised), is compared to the present value of the expected cash flows at the current reporting date. The estimated cash flows reflect those a "market participant" would use and are discounted at a rate equal to the current yield used to accrete interest income. If an other-than-temporary impairment is recognized as a result of this analysis, the yield is maintained at the current accretion rate. The last revised estimated cash flows are then used for future impairment analysis purposes. The Company's prepayment speed estimate was the primary assumption used to determine other-than temporary-impairments for Interest-Only Strips, excluding Agency and Non-Agency Interest-Only Strips accounted for as derivatives, for the years ended December 31, 2016, December 31, 2015 and December 31, 2014.
With respect to the Company's security portfolio, OTTI is generally recorded when the credit quality of the underlying collateral deteriorates and or the schedule payments are faster than previously projected. The credit deterioration could be as a result of, but not limited to, increased projected realized losses, foreclosures, delinquencies and the likelihood of the borrower being able to make payments in the future. Generally, a prepayment occurs when a loan has a higher interest rate relative to current interest rates and lenders are willing to extend credit at the lower current interest rate of the underlying collateral for the loan is sold or transferred.
The following table presents the OTTI the Company recorded on its securities portfolio (dollars in thousands):

The Company has made investments in certain Non-Agency RMBS inverse floaters. The coupon rate on these securities has an inverse relationship to a benchmark rate. When the benchmark interest rate increases the coupon payment rate will decrease because the benchmark interest rate is deducted from the coupon payment. The Company has generally purchased these securities at a premium. Accelerated prepayments on these securities could result in an economic loss, as the Company would not recover the upfront premium. The premiums are amortized into income using the effective interest rate method. As of December 31, 2016, December 31, 2015 and December 31, 2014, the Company held $62.3 million, $79.1 million and $93.9 million, respectively, in Non-Agency RMBS inverse floaters.
The following table presents components of interest income on the Company's MBS and other securities (dollars in thousands) for the three years ended December 31, 2016, December 31, 2015 and December 31, 2014, respectively:

Residential Whole-Loan Trusts
The consolidated financial statements also include the consolidation of certain trusts that each meet the definition of a VIE related to the acquisition of Residential Whole-Loans in which the Company has determined itself to be the primary beneficiary of each such trust. The Company determined that it was the primary beneficiary of the two residential Whole-Loan trusts, which were merged into one trust during the first quarter of 2016, because it was involved in certain aspects of the design of each trust, has certain oversight rights on defaulted assets and has other significant decision making powers. In addition, the Company has the obligation to absorb losses and the right to receive benefits from the trust that could potentially be significant to the trust. The trust has issued a trust certificate to the Company which represents the beneficial interest in pools of Residential Whole-Loans held by the trust. As of December 31, 2016 and 2015, the Company financed the trust certificate with $154.4 million and $173.9 million, respectively, of repurchase borrowings, which is a liability held outside the trust. The Company classifies the underlying Residential Whole-Loans owned by the trust in "Residential Whole-Loans, at fair value" in the Consolidated Balance Sheets and has eliminated the intercompany trust certificate in consolidation.
Commercial Loan Trust
In November 2015, the Company acquired a $14.0 million interest in the trust certificate issued by CMSC Trust 2015—Longhouse MZ ("CMSC Trust"), with a fair value of $13.6 million at December 31, 2016 which is financed with $6.8 million of repurchase borrowings. The Company determined that CMSC Trust was a VIE and itself the primary beneficiary because it was involved in certain aspects of the design of the trust, has certain oversight rights on defaulted assets and has other significant decision making powers. In addition, the Company has the obligation to absorb losses and the right to receive benefits from the trust that could potentially be significant to the trust. The CMSC Trust holds a $25.0 million mezzanine loan collateralized by interests in commercial real estate. The mezzanine loan serves as collateral for the $25.0 million of trust certificates issued. As of December 31, 2016, the Company classified the mezzanine loan at fair value in "Securitized commercial loan, at fair value" in the Consolidated Balance Sheets. The $25.0 million of trust certificates, of which $14.0 million was eliminated in consolidation and the remaining $11.0 million held by an affiliate is carried at fair value of $10.7 million and classified as "Securitized debt, at fair value" in the Consolidated Balance Sheets.
The Company assesses modifications 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 two consolidated trusts hold 475 performing Residential Whole-Loans and one performing commercial loan. The following table presents a summary of the assets and liabilities of the residential and commercial loan trusts included in the Consolidated Balance Sheets as of December 31, 2016 and December 31, 2015 (dollars in thousands):

The Company's risk with respect to its investment in each trust is limited to its direct ownership in the trust. The Residential Whole-Loans and securitized commercial loan held by the consolidated trusts are held solely to satisfy the liabilities of the trust, and creditors of the trust have no recourse to the general credit of the Company for the trust certificates issued by the trusts. The assets of a consolidated trust can only be used to satisfy the obligations of that trust. The Company is not contractually required and has not provided any additional financial support to the trusts for the years ended December 31, 2016 and December 31, 2015. The Company did not deconsolidate any trusts during the year ended December 31, 2016.

Whole-loans consist of Residential Whole-Loans and securitized commercial loan. Repurchase agreement borrowings on the Residential Whole-Loans and securitized commercial loan owned through trust certificates. The trust certificates are eliminated in consolidation.
For the years ended December 31, 2016 and December 31, 2015, the Company had average borrowings under its repurchase agreements of approximately $2.5 billion and $3.4 billion, respectively, and had a maximum month-end balance during the periods of approximately $3.1 billion and $4.0 billion, respectively. The Company had accrued interest payable at December 31, 2016 and December 31, 2015 of approximately $3.2 million and $3.0 million, respectively. In addition, at December 31, 2016, the Company had entered into repurchase agreement borrowings of approximately $193.7 million, which settled by January 6, 2017, with a weighted average interest rate of 1.36%, a weighted average contractual maturity of 52 days and secured by collateral of approximately $213.0 million. These borrowings are recorded as a liability in the Company's Consolidated Balance Sheets when settled.
The repurchase agreements bear interest at a contractually agreed-upon rate and typically have terms ranging from one month to three months. The Company's repurchase agreement borrowings are accounted for as secured borrowings when the Company maintains effective control of the financed assets. Under the repurchase agreements, the respective counterparties retain the right to determine the fair value of the underlying collateral. A reduction in the value of pledged assets requires the Company to post additional securities as collateral, pay down borrowings or establish cash margin accounts with the counterparties in order to re-establish the agreed-upon collateral requirements, and is referred to as a margin call. The inability of the Company to post adequate collateral for a margin call by a counterparty, in a timeframe as short as the close of the same business day, could result in a condition of default under the Company's repurchase agreements, thereby enabling the counterparty to liquidate the collateral pledged by the Company, which may have a material adverse effect on the Company's financial position, results of operations and cash flows. The Company may also rehypothecate pledged U.S. Treasury securities it receives from its repurchase agreement and interest rate swap counterparties as incremental collateral in order to increase the Company's cash position. At December 31, 2016 and December 31, 2015, the Company did not have any rehypothecated U.S. Treasury securities.
Volatility in the mortgage markets may create additional stress on the overall liquidity of the Company due to the long-term nature of its assets and the short-term nature of its liabilities. In an instance of severe volatility, or where the additional stress on liquidity resulting from volatility is sustained over an extended period of time, the Company could be required to sell assets, possibly even at a loss, to generate sufficient liquidity to satisfy collateral and margin requirements which could have a material adverse effect on the Company's financial position, results of operations and cash flows. The majority of the Company's repurchase agreement counterparties are either U.S. financial institutions or the U.S. broker-dealer subsidiaries of foreign financial institutions.
Further, if the Company is unable to renew, replace or expand repurchase financing with other sources of financing on substantially similar terms it may have a material adverse effect on the Company's financial position, results of operations and cash flow, due to the long term nature of the Company's investments and relatively short-term maturities of the Company's repurchase agreements. Certain of the repurchase agreements provide the counterparty with the right to terminate the agreement if the Company does not maintain certain equity and leverage metrics, the most restrictive of which include a limit on leverage based on the composition of the Company's portfolio. All the repurchase agreements with outstanding borrowings the Company was in compliance with the terms of such financial tests as of December 31, 2016.
At December 31, 2016 and December 31, 2015, repurchase agreements collateralized by investments had the following remaining maturities:

Contractual interest income (expense), net on derivative instruments includes interest settlement paid or received.


At December 31, 2016 and December 31, 2015, the Company had cash pledged as collateral for its derivatives of approximately $206.6 million and approximately $211.3 million respectively, which is reported in "Due from counterparties" in the Consolidated Balance Sheets. The Company also held cash collateral against derivatives of approximately $470 thousand and $9.4 million at December 31, 2016 and December 31, 2015, respectively, which is reported in "Due to counterparties" in the Consolidated Balance Sheets.
Interest rate swaps and interest rate swaptions
The Company enters into interest rate swaps and interest rate swaptions to mitigate its exposure to higher short-term interest rates in connection with its repurchase agreements. Interest rate swaps generally involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the interest rate swap without exchange of the underlying notional amount. Notwithstanding the foregoing, in order to manage its hedge position with regard to its liabilities, the Company on occasion will enter into interest rate swaps which involve the receipt of fixed-rate amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the interest rate swap without exchange of the underlying notional amount. The Company also enters into forward starting swaps and interest rate swaptions to help mitigate the effects of changes in interest rates on a portion of its borrowings under repurchase agreements. Interest rate swaptions provide the Company the option to enter into an interest rate swap agreement for a predetermined notional amount, stated term and pay and receive interest rates in the future. On occasion the Company may enter into a MAC interest rate swap in which it may receive or make a payment at the time of entering such interest rate swap to compensate for the out of the market nature of such interest rate swap. Similar to all other interest rate swaps, these interest rate swaps are also subject to margin requirements as previously described.
The Company has not elected to account for its interest rate swaps as "hedges" under GAAP, accordingly the change in fair value of the interest rate swaps not designated in hedging relationships are recorded together with periodic net interest settlement amounts in "Gain (loss) on derivatives instruments, net" in the Consolidated Statements of Operations.

The Company's agreements with certain of its bilateral interest rate swap counterparties may be terminated at the option of the counterparty, and settled at fair value, if the Company does not maintain certain equity and leverage metrics. The most restrictive of which contain provisions which become more restrictive based upon portfolio composition. Through December 31, 2016, the Company was in compliance with the terms of such financial tests.

Currency Swaps and Forwards
The Company has invested in and, in the future, may invest in additional securities which are denominated in a currency or currencies other than U.S. dollars. Similarly, it has and may in the future, finance such assets in a currency or currencies other than U.S. dollars. In order to mitigate the impact to the Company, the Company may enter into derivative financial instruments, including foreign currency swaps and foreign currency forwards, to manage fluctuations in the valuation between U.S. dollars and such foreign currencies. Foreign currency swaps involve the payment of a foreign currency at fixed interest rate on a fixed notional amount and the receipt of U.S. dollars at a fixed interest rate on a fixed notional amount. Foreign currency forwards provide for the payment of a fixed amount of a foreign currency in exchange for a fixed amount of U.S. dollars at a date certain in the future. The carrying value of foreign currency swaps and forwards is included in "Derivative assets, at fair value" and "Derivative liability, at fair value" in the Consolidated Balance Sheets with changes in valuation included in "Gain (loss) on derivative instruments, net" in the Consolidated Statements of Operations. The following is a summary of the Company's foreign currency forwards at December 31, 2016 and December 31, 2015 (dollars and euros in thousands):

Interest-Only Strips
The Company also invests in Interest-Only Strips. In determining the classification of its holdings of Interest-Only Strips, the Company evaluates the securities to determine if the nature of the cash flows has been altered from that of the underlying mortgage collateral. Generally, Interest-Only Strips for which the security represents a strip off of a mortgage pass through security will be considered a hybrid instrument classified as a MBS investment in the Consolidated Balance Sheets utilizing the fair value option. Alternatively, those Interest-Only Strips, for which the underlying mortgage collateral has been included into a structured security that alters the cash flows from the underlying mortgage collateral, are accounted for as derivatives at fair value with changes recognized in "Gain (loss) on derivative instruments, net" in the Consolidated Statements of Operations, along with any interest received. The carrying value of these Interest-Only Strips is included in "Mortgage-backed securities and other securities, at fair value" in the Consolidated Balance Sheets.
Total Return Swap
 
In 2016, the Company has entered into a total return swap and in the future may continue to enter into these types of credit derivatives. This swap transfers the total return of the referenced asset, including interim cash flows and capital appreciation or depreciation from a specified price to the Company.  The total return swap has a referenced asset which is a security collateralized by residential loans with a notional amount of €51.0 million.  The Company receives interest from the referenced asset equal to EURIBOR plus 2.75% and is required to pay the counterparty EURIBOR plus 0.50% through June 23, 2019, with the spread decreasing to 0.25% through December 2019, with the spread further decreasing to 0% through the maturity date of the referenced asset in December 2020.  As of December 31, 2016, the Company has posted $8.4 million in cash collateral which is recorded in "Due from counterparties" in the Consolidated Balance Sheets.

Management Agreement
In connection with the Company's IPO in May 2012, the Company entered into a management agreement (the "Management Agreement") with the Manager, which describes the services to be provided by the Manager and compensation for such services. The Manager is responsible for managing the Company's operations, including: (i) performing all of its day-to-day functions; (ii) determining investment criteria in conjunction with the Board of Directors; (iii) sourcing, analyzing and executing investments, asset sales and financings; (iv) performing asset management duties; and (v) performing financial and accounting management, subject to the direction and oversight of the Company's Board of Directors. Pursuant to the terms of the Management Agreement, the Manager is paid a management fee equal to 1.50% per annum of the Company's stockholders' equity (as defined in the Management Agreement), calculated and payable (in cash) quarterly in arrears. For purposes of calculating the management fee, "stockholders' equity" means the sum of the net proceeds from any issuances of the Company's equity securities since inception (allocated on a pro rata daily basis for such issuances during the fiscal quarter of any such issuance), plus retained earnings, calculated in accordance with GAAP, at the end of the most recently completed fiscal quarter (without taking into account any non-cash equity compensation expense incurred in current or prior periods), less any amount paid for repurchases of the Company's shares of common stock, excluding any unrealized gains, losses or other non-cash items, (including OTTI charges prior to January 1, 2016); unrealized gain (loss), net; and the non-cash portion of gain (loss) on derivative instruments, that have impacted stockholder's equity as reported in the Company's consolidated financial statements prepared in accordance with GAAP, regardless of whether such items are included in other comprehensive income or loss, or in net income, and excluding one-time events pursuant to changes in GAAP and certain other non-cash charges after discussions between the Manager and the Company's independent directors and after approval by a majority of the Company's independent directors. However, if the Company's stockholders' equity for any given quarter is negative based on the calculation described above, the Manager will not be entitled to receive any management fee for that quarter.
On August 3, 2016, the Company and the Manager entered into an amendment to the Management Agreement that amended the definition of "Equity" in the Management Agreement. Under the new definition, for all periods beginning on January 1, 2016, OTTI will reduce the Company's "Equity" for any completed fiscal quarter that OTTI was recognized, which in turn will reduce the Company's management fee from what would have been payable before the amendment.
In addition, the Company may be required to reimburse the Manager for certain expenses as described below, and shall reimburse the Manager for the compensation paid to the Company's CFO, controller and their staff. Expense reimbursements to the Manager are made in cash on a regular basis. The Company's reimbursement obligation is not subject to any dollar limitation. Because the Manager's personnel perform certain legal, accounting, due diligence tasks and other services that outside professionals or outside consultants otherwise would perform, the Manager may be paid or reimbursed for the documented cost of performing such tasks, provided that such costs and reimbursements are in amounts which are no greater than those which would be payable to outside professionals or consultants engaged to perform such services pursuant to agreements negotiated on an arm's-length basis.
The Management Agreement may be amended, supplemented or modified by agreement between the Company and the Manager. The Management Agreement expires on May 16, 2018. It is automatically renewed for one year terms on each May 15th unless previously terminated as described below. The Company's independent directors review the Manager's performance and any fees payable to the Manager annually and, the Management Agreement may be terminated annually upon the affirmative vote of at least two-thirds (2/3) of the Company's independent directors, based upon: (i) the Manager's unsatisfactory performance that is materially detrimental to the Company; or (ii) the Company's determination that any fees payable to the Manager are not fair, subject to the Manager's right to prevent such termination due to unfair fees by accepting a reduction of management fees agreed to by at least two-thirds (2/3) of the Company's independent directors. The Company will provide the Manager 180 days prior notice of any such termination. Unless terminated for cause, the Company will pay the Manager a termination fee equal to three times the average annual management fee earned by the Manager during the prior 24-month period immediately preceding the date of termination, calculated as of the end of the most recently completed fiscal quarter prior to the date of termination.
The Company may also terminate the Management Agreement at any time, without the payment of any termination fee, with 30 days prior written notice from the Company's Board of Directors for cause, which will be determined by at least two-thirds (2/3) of the Company's independent directors, which is defined as: (i) the Manager's continued material breach of any provision of the Management Agreement (including the Manager's failure to comply with the Company's investment guidelines); (ii) the Manager's fraud, misappropriation of funds, or embezzlement against the Company; (iii) the Manager's gross negligence in the performance of its duties under the Management Agreement; (iv) the occurrence of certain events with respect to the bankruptcy or insolvency of the Manager, including an order for relief in an involuntary bankruptcy case or the Manager authorizing or filing a voluntary bankruptcy petition; (v) the Manager is convicted (including a plea of nolo contendere) of a felony; or (vi) the dissolution of the Manager.
For the years ended December 31, 2016, December 31, 2015 and December 31, 2014 the Company incurred approximately $10.4 million, approximately $10.9 million and approximately $9.6 million in management fees, respectively.
In addition to the management fee, the Company is also responsible for reimbursing the Manager for certain expenses paid by the Manager on behalf of the Company, as defined in the Management Agreement. For the years ended December 31, 2016, December 31, 2015 and December 31, 2014, the Company recorded expenses included in general and administrative expense totaling approximately $740 thousand, $1.2 million and $624 thousand, respectively, related to reimbursable employee costs. Any such expenses incurred by the Manager and reimbursed by the Company, including the employee compensation expense, are typically included in the Company's general and administrative expense in the Consolidated Statements of Operations, or may be reflected in the Consolidated Balance Sheets and associated Consolidated Statements of Changes in Stockholders' Equity, based on the nature of the item. At December 31, 2016 and December 31, 2015, approximately $2.5 million and approximately $2.7 million, respectively for management fees incurred but not yet paid was included in "Payable to related party" in the Consolidated Balance Sheets. In addition, at December 31, 2016 and December 31, 2015, approximately $83 thousand and $277 thousand, respectively of reimbursable costs incurred but not yet paid was included in "Payable to related party" in the Consolidated Balance Sheets.
Securitized debt
At December 31, 2016 and December 31, 2015, the Company had securitized debt related to the consolidated VIEs, with a principal balance of $11.0 million and $11.0 million, respectively (and a fair value of $10.7 million and $11.0 million, respectively) which was held by an affiliate. The securitized debt of the VIEs can only be settled with the commercial loans that serve as collateral of the VIE and is non-recourse to the Company.

Share-Based Payments
In conjunction with the Company's IPO and concurrent private placement, the Company's Board of Directors approved the Western Asset Mortgage Capital Corporation Equity Plan (the "Equity Plan") and the Western Asset Manager Equity Plan (the "Manager Equity Plan" and collectively the "Equity Incentive Plans"). The Equity Incentive Plans include provisions for grants of restricted common stock and other equity-based awards to the Manager, its employees and employees of its affiliates and to the Company's directors, officers and employees. The Company can issue up to 3.0% of the total number of issued and outstanding shares of its common stock (on a fully diluted basis) at the time of each award (other than any shares previously issued or subject to awards made pursuant to one of the Company's Equity Incentive Plans) under these Equity Incentive Plans. At May 15, 2012, there were 308,335 shares of common stock initially reserved for issuance under the Equity Incentive Plans. Upon the completion of the October 3, 2012 follow-on common stock offering, the stock portion of the Company's dividend declared December 19, 2013, and the April 9, 2014 follow-on offering (which includes the partial exercise of the overallotment option on May 7, 2014) and private placement of common stock, the number of shares of common stock available for issuance under the Equity Incentive Plans increased to 1,237,711, inclusive of 681,970 shares of restricted stock granted and 25,891 shares of restricted stock issued as a result of the stock portion of the dividend declared on December 19, 2013 and restricted stock attributed to dividends on restricted stock under the Director Deferred Fee Plan. As of December 31, 2016, 529,850 shares remained available for issuance under the Equity Incentive Plans.
The Company made the following grants under the Equity Plan for the years ended December 31, 2016 and December 31, 2015:
On June 2, 2016, the Company granted a total of 17,132 (4,283 each) of restricted common stock under the Equity Plan to the Company’s four independent directors.  These restricted shares will vest in full on June 2, 2017, the first anniversary of the grant date. Each of the independent directors has elected to defer the shares granted to him under the Director Deferred Fee Plan (the "Director Deferred Fee Plan"). The Director Deferred Fee Plan permits eligible members of the Company’s board of directors to defer certain stock awards made under its director compensation programs. The Director Deferred Fee Plan allows directors to defer issuance of their stock awards and therefore defer payment of any tax liability until the deferral is terminated, pursuant to the election form executed each year by each eligible director.
On March 1, 2015, the Company granted 200,000 shares of restricted common stock to the Manager under the Manager Equity Plan. One-third of the shares vested on March 1, 2016, one-third will vest on March 1, 2017 and the remaining one-third will vest on March 1, 2018.
On June 4, 2015, the Company granted a total of 10,500 (2,625 each) of restricted common stock under the Equity Plan to the Company's four independent directors. These restricted shares vested in full on June 4, 2016, the first anniversary of the grant date. Each of the independent directors has elected to defer the shares granted to him under the Company's Director Deferred Fee Plan.
On December 8, 2015, the Company's then chief financial officer passed away and the board of directors approved the accelerated vesting of 13,980 shares of restricted common stock. The Company recognized $66 thousand of compensation expense recorded in "Compensation expense" in the Consolidated Statements of Operations for the year ended December 31, 2015.
During the years ended December 31, 2016, December 31, 2015 and December 31, 2014, 200,983, 175,824 and 87,819 restricted common shares vested, respectively, including shares whose issuance has been deferred under the Director Deferred Fee Plan. The Company recognized stock-based compensation expense of approximately $1.7 million, approximately $2.3 million and approximately $2.2 million for the years ended December 31, 2016, December 31, 2015 and December 31, 2014, respectively. In addition, the Company had unamortized compensation expense of $67 thousand for equity awards and approximately $895 thousand for liability awards and $67 thousand for equity awards and approximately $2.4 million for liability awards at December 31, 2016 and December 31, 2015, respectively.
All restricted common shares granted, other than those whose issuance has been deferred pursuant to the Director Deferred Fee Plan, possess all incidents of ownership, including the right to receive dividends and distributions currently, and the right to vote. Dividend equivalent payments otherwise allocable to restricted common shares under the Deferred Compensation Plan are deemed to purchase additional phantom shares of the Company's common stock that are credited to each participant's deferral account. The award agreements include restrictions whereby the restricted shares cannot be sold, assigned, transferred, pledged, hypothecated or otherwise disposed of prior to the lapse of restrictions under the respective award agreement. The restrictions lapse on the unvested restricted shares awarded when vested, subject to the grantee's continuing to provide services to the Company as of the vesting date. Unvested restricted shares and rights to dividends thereon are forfeited upon termination of the grantee.
The following is a summary of restricted common stock vesting dates as of December 31, 2016 and December 31, 2015, including shares whose issuance has been deferred under the Director Deferred Fee Plan:

Warrants
On May 9, 2012, the Company entered into agreements with certain institutional investors to sell 2,231,787 warrant units.

As of December 31, 2016, the adjusted exercise price of the warrants was $16.70 and there were a total of 1,232,916 warrant shares purchasable. The warrants expire on May 15, 2019.
Stock Repurchase Program
On February 25, 2016, the Board of Directors of the Company reauthorized its repurchase program of up to 2,050,000 shares of its common stock through December 31, 2017. The original authorization expired on December 31, 2015. Purchases made pursuant to the program will be made in the open market, in privately negotiated transactions, or pursuant to any trading plan that may be adopted in accordance with Rules 10b5-1 and 10b-18 of the Securities and Exchange Commission. The authorization does not obligate the Company to acquire any particular amount of common shares and the program may be suspended or discontinued at the Company's discretion without prior notice. The timing, manner, price and amount of any repurchases will be determined by the Company in its discretion and will be subject to economic and market conditions, stock price, applicable legal requirements and other factors. The Company has not repurchased any shares of common stock pursuant to the authorization as of December 31, 2016.

Income Taxes
Income Taxes
As a REIT, the Company is not subject to federal income tax to the extent that it makes qualifying distributions to its stockholders and satisfies on a continuing basis, through actual investment and operating results, the REIT requirements including certain asset, income and stock ownership tests.
Based on the Company's analysis of any potential uncertain income tax positions, the Company concluded that it does not have any uncertain tax positions that meet the recognition or measurement criteria as of December 31, 2016. The Company files U.S. federal and state income tax returns. As of December 31, 2016, U.S. federal tax returns filed by the Company for 2015, 2014 and 2013 and state tax returns filed for 2015, 2014, 2013 and 2012 are open for examination pursuant to relevant statutes of limitation. In the event that the Company incurs income tax related interest and penalties, the Company's policy is to classify them as a component of its provision for income taxes.
Deferred Tax Asset

As of December 31, 2016, the Company recorded a deferred tax asset of approximately $6.5 million relating to capital loss carryforward and temporary differences as a result of the timing of income recognition of certain investments held in the TRS. The capital loss carryforwards and temporary differences may only be recognized to the extent of capital gains. There is uncertainty as to the TRS ability to recognize capital gains in the future. As a result, the Company has concluded it is more likely than not the deferred tax asset will not be realized and has recorded a full valuation allowance.

The following table discloses the components of the Company's deferred tax asset at December 31, 2016 and 2015 (dollars in thousands):

Income Tax Provision
Subject to the limitation under the REIT asset test rules, the Company is permitted to own up to 100% of the stock of one or more TRS. Currently, the Company owns one TRS that is taxable as a corporation and is subject to federal, state and local income tax on its net income at the applicable corporate rates. The TRS, which was formed in Delaware on July 28, 2014, is a limited liability company and a wholly-owned subsidiary of the Company. For the year ended December 31, 2016, the Company recorded a federal and state tax provision of approximately $3.2 million. In addition, on completion and filing of its 2015 federal and state tax returns in September 2016 for the TRS, the Company incurred an additional tax liability of approximately $2.0 million due to changes in the estimated taxable income from certain investments, which is recorded in "Income tax provision (benefit)" in the Consolidated Statements of Operations.

Summary of Significant Accounting Policies (Policies)
12 Months Ended
Dec. 31, 2016
Accounting Policies [Abstract]  
Basis of Presentation and Consolidation
Basis of Presentation and Consolidation
The consolidated financial statements of the Company are prepared in accordance with generally accepted accounting principles in the United States ("GAAP"). The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and variable interest entities ("VIEs") in which it is considered the primary beneficiary. Refer to Note 5—"Variable Interest Entities" for additional information regarding the impact of consolidation of theses VIE's. All intercompany amounts between the Company and its subsidiary and consolidated VIE's have been eliminated in consolidation.
Variable Interest Entities
VIEs are defined as entities that by design either lack sufficient equity for the entity to finance its activities without additional subordinated financial support or are unable to direct the entity's activities or are not exposed to the entity's losses or entitled to its residual returns. The Company evaluates all of its interests in VIEs for consolidation. When the interests are determined to be variable interests, the Company assesses whether it is deemed the primary beneficiary. The primary beneficiary of a VIE is determined to be the party that has both the power to direct the activities of a VIE that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE.
To assess whether the Company has the power to direct the activities of a VIE that most significantly impact the VIE's economic performance, it considers all facts and circumstances, including its role in establishing the VIE and its ongoing rights and responsibilities. This assessment includes first, identifying the activities that most significantly impact the VIE's economic performance; and second, identifying which party, if any, has power over those activities. In general, the parties that make the most significant decisions affecting the VIE or have the right to unilaterally remove those decision makers is deemed to have the power to direct the activities of a VIE.
To assess whether the Company has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, it considers all of its economic interests. This assessment requires the Company to apply judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Factors considered in assessing significance include: the design of the VIE, including its capitalization structure; subordination of interests; payment priority; relative share of interests held across various classes within the VIE's capital structure; and the reasons why the interests are held by the Company.
In instances when a VIE is owned by both the Company and related parties, the Company considers whether there is a single party in the related party group that meets both the power and losses or benefits criteria on its own as though no related party relationship existed. If one party within the related party group meets both these criteria, such reporting entity is the primary beneficiary of the VIE and no further analysis is needed. If no party within the related party group on its own meets both the power and losses or benefits criteria, but the related party group does as a whole meets these two criteria, the determination of primary beneficiary within the related party group is based upon an analysis of the facts and circumstances with the objective of determining which party is most closely associated with the VIE. Determining the primary beneficiary within the related party group requires significant judgment.
In instances when the Company is required to consolidate a VIE that is determined to be a qualifying collateralized financing entity, under GAAP, the Company will measure both the financial assets and financial liabilities of the VIE using the fair value of either the VIE's financial assets or financial liabilities, whichever is more observable.
Ongoing assessments of whether an enterprise is the primary beneficiary of a VIE are required.
Use of Estimates
Use of Estimates
The preparation of the consolidated financial statements 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 periods. Actual results could differ from those estimates.
Reclassification
Reclassification
Certain prior period amounts have been reclassified in the consolidated financial statements to conform to current period presentation.
Earnings (Loss) per share
Earnings (Loss) per share
GAAP requires use of the two-class method in computing earnings per share for all periods presented for each class of common stock and participating securities as if all earnings for the period had been distributed. Under the two-class method, during periods of net income, the net income is first reduced for dividends declared on all classes of securities to arrive at undistributed earnings. During periods of net losses, the net loss is reduced for dividends declared on participating securities only if the security has the right to participate in the earnings of the entity and an objectively determinable contractual obligation to share in net losses of the entity. The Company's participating securities are not allocated a share of the net loss, as the participating securities do not have a contractual obligation to share in the net losses of the Company.
The remaining earnings are allocated to common stockholders and participating securities, to the extent that each security shares in earnings, as if all of the earnings for the period had been distributed. Each total is then divided by the applicable number of weighted average outstanding common shares outstanding to arrive at basic earnings per share. For the diluted earnings, the denominator includes the weighted average outstanding common shares and all potential common shares assumed issued if they are dilutive. The numerator is adjusted for any changes in income or loss that would result from the assumed conversion of these potential common shares.
Offering Costs
Offering Costs
Offering costs borne by the Company in connection with common stock offerings and private placements are reflected as a reduction of additional paid-in-capital.
Cash and Cash Equivalents
Cash and Cash Equivalents
The Company considers all highly-liquid short term investments with original maturities of 90 days or less when purchased to be cash equivalents. Cash and cash equivalents are exposed to concentrations of credit risk. The Company places its cash and cash equivalents with what it believes to be high credit quality institutions. At times such investments may be in excess of the Federal Deposit Insurance Corporation insurance limit.
Mortgage-Backed Securities and Other Securities
Mortgage-Backed Securities and Other Securities
The Company's mortgage-backed securities and other securities portfolio primarily consists of Agency RMBS, Non-Agency RMBS, Agency CMBS and Non-Agency CMBS, ABS and other real estate related assets, these investments are recorded in accordance with ASC 320, “Investments – Debt and Equity Securities”, ASC 325-40, “Beneficial Interests in Securitized Financial Assets” or ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality”. The Company has chosen to make a fair value election pursuant to ASC 825, “Financial Instruments” for its mortgage-backed securities and other securities portfolio. Electing the fair value option allows the Company to record changes in fair value in the Consolidated Statements of Operations as a component of “Unrealized gain (loss), net”.
When the Company purchases securities with evidence of credit deterioration since origination, it will analyze to determine if the guidance found in ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality” is applicable.
The Company accounts for its securities under ASC 310 and ASC 325 and evaluates securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis. The determination of whether a security is other-than-temporarily impaired involves judgments and assumptions based on subjective and objective factors. When the fair value of an investment security is less than its amortized cost at the balance sheet date, the security is considered impaired, and the impairment is designated as either “temporary” or “other-than-temporary.” When a security is impaired, an OTTI is considered to have occurred if (i) the Company intends to sell the security (i.e., a decision has been made as of the reporting date) or (ii) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell the security or if it is more likely than not that the Company will be required to sell the real estate security before recovery of its amortized cost basis, the entire amount of the impairment loss, if any, is recognized in earnings as OTTI and the cost basis of the security is adjusted to its fair value. Additionally for securities accounted for under ASC 325-40 an OTTI is deemed to have occurred when there is an adverse change in the expected cash flows to be received and the fair value of the security is less than its carrying amount. In determining whether an adverse change in cash flows occurred, the present value of the remaining cash flows, as estimated at the initial transaction date (or the last date previously revised), is compared to the present value of the expected cash flows at the current reporting date. The estimated cash flows reflect those a “market participant” would use and are discounted at a rate equal to the current yield used to accrete interest income. Any resulting OTTI adjustments are reflected in the “Other than temporary impairment” line item in the Consolidated Statements of Operations.
The determination as to whether an OTTI exists is subjective, given that such determination is based on information available at the time of assessment as well as the Company’s estimate of the future performance and cash flow projections for the individual security. As a result, the timing and amount of an OTTI constitutes an accounting estimate that may change materially over time.

Increases in interest income may be recognized on a security on which the Company previously recorded an OTTI charge if the cash flow of such security subsequently improves.

Securities in an unrealized loss position on December 31, 2016, are not considered other than temporarily impaired if the Company had the ability and intent to hold the securities to maturity or for a period of time sufficient for a forecasted market price recovery up to or above the amortized cost of the investment, and the Company was not required to sell the security for regulatory or other reasons.

In addition, unrealized losses on the Company's Agency securities, with explicit guarantee of principal and interest by the governmental sponsored entity ("GSE"), are not credit losses but rather were due to changes in interest rates and prepayment expectations. These securities would not be considered other than temporarily impaired provided we did not intend to sell the security.
Residential Whole-Loans
Residential Whole-Loans
Investments in Whole-Loans are recorded in accordance with ASC 310-20, "Nonrefundable Fees and Other Costs". The Company has chosen to make the fair value election pursuant to ASC 825 for its Whole-Loan portfolio. Whole-Loans are recorded at fair value in the Consolidated Balance Sheets with the periodic change in fair value being recorded in earnings in the Consolidated Statements of Operations as a component of "Unrealized gain (loss), net". All other costs incurred in connection with acquiring Whole-Loans or committing to purchase these loans are charged to expense as incurred.
The Company amortizes or accretes any premium or discount over the life of the related loan utilizing the effective interest method, based on the contractual payment terms of the loan. On at least a quarterly basis, the Company evaluates the collectability of both interest and principal of each loan, if circumstances warrant, to determine whether such loan is impaired. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the existing contractual terms. When a loan is impaired, the Company does not record an allowance for loan loss as the Company has elected the fair value option. However, income recognition is suspended for loans at the earlier of the date at which payments become 90-days past due or when, in the opinion of management, a full recovery of income and principal becomes doubtful. When the ultimate collectability of the principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. When the ultimate collectability of the principal of an impaired loan is not in doubt, contractual interest is recorded as interest income when received, under the cash basis method until an accrual is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. A loan is written off when it is no longer realizable and/or legally discharged.
Valuation of financial instruments
Valuation of Financial Instruments
The Company discloses the fair value of its financial instruments according to a fair value hierarchy (Levels I, II, and III, as defined below). ASC 820 "Fair Value Measurements and Disclosures" establishes a framework for measuring fair value and expands financial statement disclosure requirements for fair value measurements. ASC 820 further specifies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation technique are observable or unobservable. The hierarchy is as follows:
Level I—Quoted prices in active markets for identical assets or liabilities.
Level II—Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
Level III—Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable, for example, when there is little or no market activity for an investment at the end of the period, unobservable inputs may be used.
The level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Transfers between levels are determined by the Company at the end of the reporting period. See Note 3 Fair Value of Financial Instruments.
Interest income recognition
Interest income recognition
Agency MBS, Non-Agency MBS and other securities, excluding Interest-Only Strips, rated AA and higher at the time of purchase
Interest income on mortgage-backed and other securities is accrued based on the respective outstanding principal balances and corresponding contractual terms. The Company records interest income in accordance with ASC subtopic 835-30 "Imputation of Interest", using the effective interest method. As such premiums and discounts associated with Agency MBS, Non-Agency MBS and other securities, excluding Interest-Only Strips, rated AA and higher at the time of purchase, are amortized into interest income over the estimated life of such securities. Adjustments to premium and discount amortization are made for actual prepayment activity. The Company estimates prepayments at least quarterly for its securities and, as a result, if the projected prepayment speed increases, the Company will accelerate the rate of amortization on premiums or discounts and make a retrospective adjustment to historical amortization. Alternatively, if projected prepayment speeds decrease, the Company will reduce the rate of amortization on the premiums or discounts and make a retrospective adjustment to historical amortization.
Non-Agency MBS and other securities that are rated below AA at the time of purchase and Interest-Only Strips that are not classified as derivatives
Interest income on Non-Agency MBS and other securities that are rated below AA at the time of purchase and Interest-Only Strips that are not classified as derivatives are also recognized in accordance with ASC 835, using the effective yield method. The effective yield on these securities is based on the projected cash flows from each security, which is estimated based on the Company's observation of the then current information and events, where applicable, and will include assumptions related to interest rates, prepayment rates and the timing and amount of credit losses. On at least a quarterly basis, the Company reviews and, if appropriate, makes adjustments to its cash flow projections based on input and analysis received from external sources, internal models, and its judgment about interest rates, prepayment rates, the timing and amount of credit losses, and other factors. Where appropriate, the Company may include in its cash flow projections the U.S. Department of Justice's settlements with the major residential mortgage originators, regarding certain lending practices. 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 securities are affected by the contractual lives of the underlying collateral, periodic payments of scheduled principal, and prepayments of principal. Therefore, actual maturities of the securities will generally be shorter than stated contractual maturities.
Based on the projected cash flow of such securities purchased at a discount to par value, the Company may designate a portion of such purchase discount as credit protection against future credit losses and, therefore, not accrete such amount into interest income. The amount designated as credit discount 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 credit discount is more favorable than forecasted, a portion of the amount designated as credit discount may be accreted into interest income prospectively.
Residential Whole-Loans
Interest income on the Company's Whole-Loan portfolio is recorded in accordance with ASC 835 using the effective interest method. Any amortization or accretion will be reflected as a component of "Interest income" in the Consolidated Statements of Operations.
Purchases and Sales of Investments
Purchases and Sales of Investments
The Company accounts for a contract for the purchase or sale of securities, or other securities that do not yet exist on a trade date basis, which it intends to take possession and thus recognizes the acquisition or disposition of the securities at the inception of the contract.
Sales of investments are driven by the Company's portfolio management process. The Company seeks to mitigate risks including those associated with prepayments and will opportunistically rotate the portfolio into securities and/or other investments the Company's Manager believes have more favorable attributes. Strategies may also be employed to manage net capital gains, which need to be distributed for tax purposes. Realized gains or losses on sales of investments, including Agency Interest-Only Strips not characterized as derivatives, are a component of "Realized gain (loss) on sale of investments, net" in the Consolidated Statements of Operations, and are recorded at the time of disposition. Realized gains losses on Interest-Only Strips which are characterized as derivatives are a component of "Gain (loss) on derivative instruments, net" in the Consolidated Statements of Operations.
Foreign currency transactions
Foreign currency transactions
The Company has and expects to continue to enter into transactions denominated in foreign currency from time to time. At the date the transaction is recognized, the asset and/or liability will be measured and recorded using the exchange rate in effect at the date of the transaction. At each balance sheet date, such foreign currency assets and liabilities are re-measured using the exchange rate in effect at the date of the balance sheet, resulting in unrealized foreign currency gains or losses, which are recorded in "Other, net" in the Consolidated Statement of Operations.
Due from counterparties/Due to counterparties
Due from counterparties/Due to counterparties
Due from counterparties represents cash posted by the Company with its counterparties as collateral for the Company's interest rate and/or currency derivative financial instruments, repurchase agreements, and TBAs. Due to counterparties represents cash posted with the Company by its counterparties as collateral under the Company's interest rate and/or currency derivative financial instruments, repurchase agreements, and TBAs. Included in the due from counterparties and/or due to counterparties are daily variation margin settlement amounts with counterparties which are based on the price movement of the Company's futures contracts. In addition, as provided below, Due to counterparties may include non-cash collateral in which the Company has the obligation to return and which the Company has either sold or pledged. To the extent the Company receives collateral other than cash from its counterparties such assets are not included in the Company's Consolidated Balance Sheets. Notwithstanding the foregoing, if the Company either rehypothecates such assets or pledges the assets as collateral pursuant to a repurchase agreement, the cash received and the corresponding liability are reflected in the Consolidated Balance Sheets.
Derivatives and hedging activities
Derivatives and hedging activities
Subject to maintaining its qualification as a REIT for U.S. federal income tax purposes, the Company utilizes derivative financial instruments, including interest rate swaps, interest rate swaptions, mortgage put options, currency forwards, futures contracts, TBAs and Agency and Non-Agency Interest-Only Strips to hedge the interest rate and currency risk associated with its portfolio and related borrowings. Derivatives, subject to REIT requirements, are used for hedging purposes rather than speculation. The Company has also entered into a total return swap, which transfers the total return of the referenced security to the Company. The Company determines the fair value of its derivative positions and obtains quotations from third parties, including the Chicago Mercantile Exchange or CME, to facilitate the process of determining such fair values. If the Company's hedging activities do not achieve the desired results, reported earnings may be adversely affected.
GAAP requires an entity to recognize all derivatives as either assets or liabilities on the balance sheet and to measure those instruments at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative. The fair value adjustment will affect either other comprehensive income in stockholders' equity until the hedged item is recognized in earnings or net income depending on whether the derivative instrument is designated and qualifies as a for hedge for accounting purposes and if so, the nature of the hedging activity. The Company elected not to apply hedge accounting for its derivative instruments. Accordingly, the Company records the change in fair value, of its derivative instruments, which includes net interest rate swap payments (including accrued amounts) and net currency payments/receipts (including accrued amounts) related to interest rate swaps and currency swaps, respectively in "Gain (loss) on derivative instruments, net" in its Consolidated Statements of Operations.
In the Company's Consolidated Statements of Cash Flows, premiums received or paid on termination of its interest rate swaps, excluding interest rate swaps containing an other-than-insignificant financing element and the unamortized premium of market agreed coupon ("MAC") interest rate swaps, are included in cash flows from operating activities. Notwithstanding the foregoing, proceeds and payments on settlement of swaptions, mortgage put options, futures contracts and TBAs are included in cash flows from investing activities. Proceeds and payments on settlement of forward contracts are reflected in cash flows from financing activities in the Company's Consolidated Statement of Cash Flows. While payments made at the time of entering MAC interest rate swaps are included in cash flows from investing activities, payments received by the Company upon entering MAC interest rate swaps are included in either cash flows from investing activities or cash flows from financing activities, depending on whether or not the derivative instrument includes an other-than-insignificant financing element. For MAC interest rate swaps containing an other-than-insignificant financing element, all cash flows over the life of the derivative are treated as cash flows from financing activities. Return and recovery of basis activity for MAC interest rate swaps is included in cash flows from investing activities for swaps not containing an other-than-insignificant financing element in the Company's Consolidated Statements of Cash Flows. For Agency and Non-Agency Interest-Only Strips accounted for as derivatives, the purchase, sale and recovery of basis activity is included with MBS and other securities under cash flows from investing activities in the Company's Consolidated Statements of Cash Flows.
The Company evaluates the terms and conditions of its holdings of Agency and Non-Agency Interest-Only Strips, interest rate swaptions, currency forwards, futures contracts and TBAs to determine if these instruments have the characteristics of an investment or should be considered a derivative under GAAP. In determining the classification of its holdings of Interest-Only Strips, the Company evaluates the securities to determine if the nature of the cash flows has been altered from that of the underlying mortgage collateral. Interest-Only Strips, for which the underlying mortgage collateral has been included into a structured security that alters the cash flows from the underlying mortgage collateral, are accounted for as derivatives. The carrying value of the Agency and Non-Agency Interest-Only Strips, accounted for as derivatives, is included in "Mortgage-backed securities and other securities, at fair value" in the Consolidated Balance Sheets. The carrying value of interest rate swaptions, currency forwards, futures contracts and TBAs is included in "Derivative assets, at fair value" or "Derivative liability, at fair value" in the Consolidated Balance Sheets. Interest earned or paid along with the change in fair value of these instruments accounted for as derivatives is recorded in "Gain (loss) on derivative instruments, net" in its Consolidated Statements of Operations
The Company evaluates all of its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. An embedded derivative is separated from the host contact and accounted for separately when all of the guidance criteria are met. Hybrid instruments that are remeasured at fair value through earnings, including the fair value option are not bifurcated. Derivative instruments, including derivative instruments accounted for as liabilities, are recorded at fair value and are re-valued at each reporting date, with changes in the fair value together with interest earned or paid (including accrued amounts) reported in "Gain (loss) on derivative instruments, net" in the Consolidated Statements of Operations.
Repurchase agreements and Reverse Repurchase agreements
Repurchase agreements and Reverse Repurchase agreements
Investments sold under repurchase agreements are treated as collateralized financing transactions, unless they meet sales treatment. Securities financed through a repurchase agreement remain in the Company's Consolidated Balance Sheets as assets and cash received from the lender is recorded in the Company's Consolidated Balance Sheets as a liability. Interest payable in accordance with repurchase agreements is recorded as "Accrued interest payable" in the Consolidated Balance Sheets. Interest paid (including accrued amounts) in accordance with repurchase agreements was recorded as interest expense.
The Company may borrow securities under reverse repurchase agreements to deliver a security owned and sold by the Company but pledged to a different counterparty under a separate repurchase agreement when in the Manager's view terminating the outstanding repurchase agreement is not in the Company's best interest. Cash paid to the borrower is recorded in the Company's Consolidated Balance Sheets as an asset. Interest receivable in accordance with reverse repurchase agreements is recorded as accrued interest receivable in the Consolidated Balance Sheets. The Company reflects all proceeds on reverse repurchase agreement and repayment of reverse repurchase agreement, on a net basis in the Consolidated Statements of Cash Flows. Upon sale of a pledged security, the Company recognizes an obligation to return the borrowed security in the Consolidated Balance Sheet in "Due to counterparties". The Company establishes haircuts to ensure the market value of the underlying asset remains sufficient to protect the Company in the event of default by the counterparty. Realized gains and losses associated with the sale of the security are recognized in "Realized gain (loss) on sale of investments, net" in the Consolidated Statement of Cash Flows.
Securitized debt
Securitized debt
Securitized debt was issued at par by a consolidated securitization trust. The Company has chosen to make the fair value election pursuant to ASC 825 for the debt. The debt is recorded at fair value in the Consolidated Balance Sheets with the periodic change in fair value recorded in current period earnings in the Consolidated Statements of Operations as a component of "Unrealized gain (loss), net".
Share-based compensation
Share-based compensation
The Company accounts for share-based compensation to its independent directors, to any employee, to its Manager and to employees of its Manager and its affiliates using the fair value based methodology prescribed by GAAP. Compensation cost related to restricted common stock issued to the Company's independent directors and any employee of the Company including any such restricted stock which is subject to a deferred compensation program, and any employee of the Company is measured at its fair value at the grant date, and amortized into expense over the service period on a straight-line basis. Compensation cost related to restricted common stock issued to the Manager and to employees of the Manager, including officers and certain directors, of the Company who are employees of the Manager and its affiliates is initially measured at fair value at the grant date, and amortized into expense over the vesting period on a straight-line basis and re-measured on subsequent dates to the extent the awards are unvested.
Warrants
Warrants
For the Company's warrants, the Company uses a variation of the adjusted Black-Scholes option valuation model to record the financial instruments at their relative fair values at issuance. The warrants issued with the Company's common stock in the private placement to certain accredited institutional investors on May 15, 2012, were evaluated by the Company and were recorded at their relative fair value as a component of equity at the date of issuance.
Income taxes
Income taxes
The Company operates and has elected to be taxed as a REIT commencing with its taxable year ended December 31, 2012. Accordingly, the Company will generally not be subject to corporate U.S. federal or state income tax to the extent that the Company makes qualifying distributions to stockholders, and provided that the Company satisfies, on a continuing basis, through actual investment and operating results, the REIT requirements including certain asset, income, distribution and stock ownership tests. If the Company fails to qualify as a REIT, and does not qualify for certain statutory relief provisions, the Company will be subject to U.S. federal, state and local income taxes and may be precluded from qualifying as a REIT for the subsequent four taxable years following the year in which the Company lost its REIT qualification. Accordingly, the failure to qualify as a REIT could have a material adverse impact in the Company's results of operations and amounts available for distribution to stockholders.
The dividends paid deduction for qualifying dividends paid to stockholders is computed using the Company's taxable income as opposed to net income reported in the Consolidated Statements of Operations. Taxable income, generally, will differ from net income reported in the Consolidated Statements of Operations because the determination of taxable income is based on tax regulations and not GAAP.
The Company may create and elect to treat certain subsidiaries as Taxable REIT Subsidiaries ("TRS"). 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. A domestic TRS is subject to U.S. federal, state and local corporate income taxes, and for 2016 its value may not exceed 25% of the value of the Company; however, commencing in taxable year 2018 its value may not exceed 20% of the value of the Company. If the TRS generates net income it may declare dividends to the Company, which will be included in the Company's taxable income and necessitate a distribution to its stockholders. Conversely, if the Company retains earnings at the TRS level, no distribution is required and it can increase book equity of the consolidated entity. As of December 31, 2016, the Company has a single wholly-owned subsidiary which it has elected to treat as a domestic TRS.
Current and deferred taxes are recorded on earnings (losses) recognized by the Company's TRS. Deferred income tax assets and liabilities are calculated based upon temporary differences between the Company's U.S. GAAP consolidated financial statements and the federal and state basis of assets and liabilities as of the Consolidated Balance Sheets date. The Company evaluates the realizability of its deferred tax assets and recognizes a valuation allowance if, based on available evidence, it is more likely than not that some or all of its deferred tax assets will not be realized. In evaluating the realizability of the deferred tax asset, the Company will consider the expected future taxable income, existing and projected book to tax differences as well as tax planning strategies. This analysis is inherently subjective, as it is based on forecasted earning and business and economic activity. Changes in estimates of deferred tax asset realizability, if any, are included in "Income tax provision (benefit)" in the Consolidated Statements of Operations.
Accounting standards applicable to emerging growth companies
Accounting standards applicable to emerging growth companies
The JOBS Act contains provisions that relax certain requirements for "emerging growth companies", which includes the Company. For as long as the Company is an emerging growth company, which may be up to five full fiscal years, unlike other public companies, the Company will not be required to: (i) comply with any new or revised financial accounting standards applicable to public companies until such standards are also applicable to private companies under Section 102(b)(1) of the JOBS Act; (ii) provide an auditor's attestation report on management's assessment of the effectiveness of the Company's system of internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act; (iii) comply with any new requirements adopted by the PCAOB requiring mandatory audit firm rotation or a supplement to the auditor's report in which the auditor would be required to provide additional information about the audit and the financial statements of the issuer; or (iv) comply with any new audit rules adopted by the PCAOB after April 5, 2012, unless the SEC determines otherwise. The Company currently takes advantage of some of these exemptions. The Company's qualification for remaining an emerging growth company under the five full fiscal years expires on December 31, 2017. However, the Company will no longer qualify for such exemption if its gross revenue for any year equals or exceeds $1.0 billion, the Company issues more than $1.0 billion in non-convertible debt during the three previous years, or if the Company is deemed to be a large accelerated filer.
Recent accounting pronouncements

Accounting Standards Adopted in 2016
In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements — Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” The guidance requires an entity’s management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. According to the new guidance, substantial doubt exists when conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date the financial statements are issued. The term “probable” is used consistently with its current use in U.S. GAAP for loss contingencies. Disclosures will be required if conditions give rise to substantial doubt about the entity’s ability to continue as a going concern, including whether management’s plans that are intended to mitigate those conditions will alleviate the substantial doubt when implemented. The guidance is effective for annual periods ending after December 15, 2016. The effective date is the same for both public companies and all other entities.  The 2016 adoption of the new guidance did not have a material impact on the Company’s consolidated financial statements.
 
In January 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-1, “Income Statement - Extraordinary and Unusual Items.” The guidance simplifies income statement presentation by eliminating the concept of extraordinary items. U.S. GAAP currently requires that a company separately classify, disclose and present extraordinary events and transactions. The guidance eliminates the concept of extraordinary items from U.S. GAAP.  Under the existing guidance, an entity is required to separately disclose extraordinary items, net of tax, in the income statement after income from continuing operations if an event or transaction is of an unusual nature and occurs infrequently. This separate, net-of-tax presentation (and corresponding earnings per share impact) will no longer be allowed. The existing requirement to separately present items that are of an unusual nature or occur infrequently on a pre-tax basis within income from continuing operations has been retained. The new guidance also requires similar separate presentation of items that are both unusual and infrequent. The standard is effective for periods beginning after December 15, 2015. The effective date is the same for both public companies and all other entities.  The 2016 adoption of the new guidance did not have a material impact on the Company’s consolidated financial statements.
 
In February 2015, the FASB issued ASU 2015-2, “Consolidation - Amendments to the Consolidation Analysis.” The guidance simplifies and reduces the number of consolidation models through the elimination of an indefinite deferral for certain entities and by placing more emphasis on risk of loss when determining a controlling financial interest.  The guidance affects reporting entities that are required to evaluate whether they should consolidate certain legal entities.  All legal entities are subject to reevaluation under the revised consolidation model.  The standard is effective for a public company for fiscal years, and for interim periods within fiscal years beginning after December 15, 2015.  The 2016 adoption of the new guidance did not have a material impact on the Company’s consolidated financial statements.

In April 2015, the FASB issued ASU 2015-3, “Interest - Imputation of Interest - Simplifying the Presentation of Debt Issuance Costs.” The guidance amends the presentation of debt issuance cost related to a recognized debt liability. Under the new guidance, the debt issuance costs were presented in the balance sheet as a direct deduction from the carrying amount of the recognized debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected under the new guidance. The standard is effective for a public company for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The guidance should be applied on a retrospective basis. The Company’s December 31, 2015 balance sheet was adjusted to reflect the effects of applying the new guidance on a retrospective basis and resulted in a $134 thousand reduction in Borrowings under repurchase agreements and a corresponding reduction in Other assets. Upon adoption, an entity is required to comply with the applicable disclosures for a change in an accounting principle. These disclosures include the nature of and reason for the change in accounting principle, the transition method, a description of the prior-period information that has been retrospectively adjusted, and the effect of the change on the financial statement line items (i.e., debt issuance cost asset and the debt liability). The 2016 adoption of the new guidance did not have a material impact on the Company’s consolidated financial statements.
Accounting Standards to be Adopted in Future Periods
In May 2014, the FASB issued ASU 2014-9, “Revenue from Contracts with Customers (Topic 606).” The guidance changes an entity’s recognition of revenue from contracts with customers.  The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  In addition, the new guidance requires improved disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. In March 2016, the FASB issued implementation guidance which clarifies principal versus agent considerations in reporting revenue gross versus net (ASU 2016-8). In April 2016, the FASB issued implementation guidance which clarifies the identification of performance obligations (ASU 2016-10). In May 2016, the FASB issued amendments that affect only the narrow aspects of Topic 606 (ASU2016-12). In applying the new guidance, an entity may use either a retrospective approach to each prior reporting period or a retrospective approach with the cumulative effect recognized at the date of initial application. For a public company, the standard is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is not permitted for a public entity. The Company is evaluating the new guidance and does not expect it to have a material impact on the Company’s consolidated financial statements. The Company has not yet determined the method by which it will adopt the standard in 2017.
 
In January 2016, the FASB issued ASU 2016-1, “Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The guidance improves certain aspects of recognition, measurement, presentation, and disclosure of financial instruments.  The standard is effective for a public company for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years.   The Company is currently assessing the impact that this guidance will have on its consolidated financial statements when adopted. It will apply the guidance by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption.  The guidance related to equity securities without readily determinable fair values will be applied prospectively to equity investments that exist at the date of adoption. 

In March 2016, the FASB issued ASU 2016-9, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The guidance changes the accounting for certain aspects of share-based payments to employees. The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis.  For a public company, the standard is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period.   The Company does not have direct employees and is externally managed; therefore, the adoption of this guidance will not have a material impact on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The guidance requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected by deducting an allowance for credit losses from the amortized cost basis of the financial assets. For available-for-sale debt securities, the new guidance aligns the income statement recognition of credit losses with the reporting period in which changes occur by recording credit losses through an allowance rather than a write-down and allowing subsequent reversals in credit loss estimates to be recognized in current income. The measurement of expected credit losses will be based on historical experience, current conditions and reasonable and supportable forecasts. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. For a public company, the standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption will be permitted for fiscal years beginning after December 15, 2018. The guidance should be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. For certain assets, a prospective transition approach is required. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements when adopted.

In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments (Topic 230)." The guidance is intended to reduce diversity in practice in how certain transactions are classified on the statement of cash flows. The Company is required to adopt the new guidance in the first quarter of 2018. Early adoption is permitted, provided that all of the amendments are adopted at the same time. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements when adopted.
 
 In November 2016, FASB issued ASU 2016-18 "Statement of Cash Flows (Topic 230): Restricted Cash, a consensus of the FASB's Emerging Issues Task Force." The guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents as well as disclose information about the nature of the restrictions on its cash and cash equivalents. For public business entities, the guidance is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The guidance should be applied using a retrospective transition method to each period presented. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements when adopted.
