	1. Organization
	AG Mortgage Investment Trust, Inc. (the “Company”) was incorporated in the state of Maryland on March 1, 2011. The Company is focused on investing in, acquiring and managing a diversified portfolio of residential mortgage-backed securities, or RMBS, issued or guaranteed by a government-sponsored enterprise such as Fannie Mae or Freddie Mac, or any agency of the U.S. Government such as Ginnie Mae (collectively, “Agency RMBS”), and other real estate-related securities and financial assets, including Non-Agency RMBS, ABS, CMBS and loans (as defined below).
	Non-Agency RMBS represent fixed-and floating-rate residential RMBS, issued by entities or organizations other than a U.S. government-sponsored enterprise or agency of the U.S. government, including investment grade (AAA through BBB) and non investment grade classes (BB and below). The mortgage loan collateral for residential Non-Agency RMBS consists of residential mortgage loans that do not generally conform to underwriting guidelines issued by U.S. government agencies or U.S. government-sponsored entities.
	Asset Backed Securities (“ABS”) are securitized investments similar to the aforementioned investments except the underlying assets are diverse, not only representing real estate related assets.
	Commercial Mortgage Backed Securities (“CMBS”) represent investments of fixed- and floating-rate CMBS, including investment grade (AAA through BBB) and non investment grade classes (BB and below). CMBS will be secured by, or evidence an ownership interest in, a single commercial mortgage loan or a pool of commercial mortgage loans.
	Collectively, the Company refers to Agency RMBS, Non-Agency RMBS, ABS and CMBS assets types as real estate securities.
	Commercial Loans Receivable (“loans”) are secured by an interest in commercial real estate and represent a contractual right to receive money on demand or on fixed or determinable dates.
	On March 7, 2011, AG Funds, L.P. (“AG Funds”), a Delaware limited partnership, entered into a subscription agreement with the Company and agreed to purchase 100 shares of common stock for $1,000. The subscription amount was received by the Company on April 1, 2011 making AG Funds the sole stockholder of the Company. The Company subsequently completed an initial public offering on July 6, 2011 and concurrently repurchased the 100 shares from AG Funds at their issue price.
	The Company is externally managed by AG REIT Management, LLC, a Delaware limited liability company (the “Manager”), a wholly-owned subsidiary of Angelo, Gordon & Co., L.P. (“Angelo, Gordon”), a privately-held, SEC-registered investment adviser. The Manager, pursuant to a delegation agreement dated as of June 29, 2011, has delegated to Angelo, Gordon the overall responsibility with respect to the Manager’s day-to-day duties and obligations arising under the management agreement.
	The Company conducts its operations to qualify and be taxed as a REIT under Code.
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.

	2. Summary of Significant Accounting Policies
	The accompanying consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Certain prior period amounts have been reclassified to conform to the current period’s presentation. In the opinion of management, all adjustments considered necessary for a fair presentation for the annual period of the Company’s financial position, results of operations and cash flows have been included and are of a normal and recurring nature.
	Cash and cash equivalents
	Cash is comprised of cash on deposit with financial institutions. We classify highly liquid investments with original maturities of three months or less from the date of purchase as cash equivalents. We place our cash and cash equivalents with high credit quality institutions to minimize credit risk exposure. Any cash held by the Company as collateral would be included in a due to broker line item on the consolidated balance sheet and in cash flows from financing activities on the consolidated statement of cash flows.
	Restricted cash
	Restricted cash includes cash pledged as collateral for clearing and executing trades, interest rate swaps and repurchase agreements. Restricted cash is carried at cost, which approximates fair value.
	Offering and organization costs
	The Company incurred offering and organization costs in connection with arranging the Company’s initial public offering (“IPO”), subsequent follow-on offerings of its common stock and issuances of preferred stock. The offering and other organization costs were paid out of the proceeds of the respective offerings. Offering costs in connection with the common stock offerings have been accounted for as a reduction of additional paid-in-capital. Offering costs in connection with preferred stock offerings have been accounted for as a reduction of their respective gross proceeds. Costs incurred to organize the Company have been expensed as incurred. The Company’s obligation to pay for organization and offering expenses incurred in connection with its IPO was capped at 1% of the total gross proceeds from the IPO and the concurrent private placement, and the Manager paid for such expenses incurred above the cap. See Note 9 for further details.
	Use of estimates
	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results may differ from those estimates.
	Earnings/(Loss) per share
	In accordance with the provisions of Accounting Standards Codification (“ASC”) 260, “Earnings per Share,” the Company calculates basic income/(loss) per share by dividing net income/(loss) available to common stockholders for the period by weighted-average shares of the Company’s common stock outstanding for that period. Diluted income/(loss) per share takes into account the effect of dilutive instruments, such as stock options, warrants and unvested restricted stock, but uses the average share price for the period in determining the number of incremental shares that are to be added to the weighted-average number of shares outstanding.
	Valuation of financial instruments
	The fair value of the financial instruments that the Company records at fair value will be determined by the Manager, subject to oversight of the Company’s board of directors, and in accordance with ASC 820, “Fair Value Measurements and Disclosures.” When possible, the Company determines fair value using independent data sources. ASC 820 establishes a hierarchy that prioritizes the inputs to valuation techniques giving the highest priority to readily available unadjusted quoted prices in active markets for identical assets (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements) when market prices are not readily available or reliable. The three levels of the hierarchy under ASC 820 are described below:
		•	Level 1—Quoted prices in active markets for identical assets or liabilities.
		•	Level 2—Prices determined using other significant observable inputs. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk and others.
		•	Level 3—Prices 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. Unobservable inputs reflect the Company’s assumptions about the factors that market participants would use in pricing an asset or liability, and would be based on the best information available.
	Transfers between levels are assumed to occur at the beginning of the reporting period.
	Accounting for real estate securities
	Investments in real estate securities are recorded in accordance with ASC 320. The Company has chosen to make a fair value election pursuant to ASC 825 for its real estate securities portfolio. The real estate securities are recorded at fair market value on the consolidated balance sheet and the periodic change in fair market value is recorded in current period earnings on the consolidated statement of operations as a component of “Unrealized gain/(loss) on real estate securities and loans, net.”
	These investments generally meet the requirements to be classified as available for sale under ASC 320-10-25, “Debt and Equity Securities”, which requires the securities to be carried at fair value on the consolidated balance sheet with changes in fair value charged to other comprehensive income, a component of stockholders’ equity. Electing the fair value option allows the Company to record changes in fair value in the statement of operations, which, in management’s view, more appropriately reflects the results of our operations for a particular reporting period as all securities activities will be recorded in a similar manner.
	The Company 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 an investment 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 investment security before recovery of its amortized cost basis, the entire amount of the impairment loss, if any, is recognized in earnings as a realized loss and the cost basis of the security is adjusted to its fair value. For securities accounted for under ASC 325-40, “Beneficial Interests in Securitized Financial Assets,” 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 net realized gain/(loss) line item on the consolidated statement of operations.
	Increases in interest income may be recognized on a security that an OTTI charge was taken, if the performance of such security subsequently improves. 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.
	Securities in an unrealized loss position at December 31, 2013 are not considered other than temporarily impaired as the Company has 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 cost of the investment, and the Company is not required to sell the security for regulatory or other reasons. See Note 3 for a summary of OTTI charges recorded.
	Sales of securities
	Sales of securities are driven by the Manager’s portfolio management process. The Manager seeks to mitigate risks including those associated with prepayments and will opportunistically rotate the portfolio into securities with 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 securities and derivatives, inclusive of securities accounted for as a component of linked transactions are included in the net realized gain/(loss) line item on the consolidated statement of operations. The cost of positions sold is calculated using a first in, first out, or FIFO, basis. Realized gains and losses are recorded in earnings at the time of disposition.
	Accounting for loans
	Investments in mortgage loans are recorded in accordance with ASC 310. The Company has chosen to make a fair value election pursuant to ASC 825 for its loan portfolio. Loans are recorded at fair market value on the consolidated balance sheet and any periodic change in fair market value will be recorded in current period earnings on the consolidated statement of operations as a component of “Unrealized gain/(loss) on real estate securities and loans, net.”
	The Company amortizes or accretes any premium or discount over the life of the related loan utilizing the effective interest method. 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 they are 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 amount of the loss accrual is calculated and recorded accordingly. 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.
	Investment in affiliates
	The Company’s unconsolidated ownership interests in affiliates are generally accounted for using the equity method. The underlying entities have chosen to make a fair value election pursuant to ASC 825; as such the Company will treat its investment in affiliates consistently with this election. The investment in affiliates is recorded at fair market value on the consolidated balance sheet and periodic changes in fair market value will be recorded in current period earnings on the consolidated statement of operation as a component of “Equity in earnings from affiliate.” Capital contributions, distributions and profits and losses of such entities are allocated in accordance with the terms of the applicable agreements.
	Investment consolidation
	For each investment made, the Company evaluates the underlying entity that issued the securities acquired or to which the Company makes a loan to determine the appropriate accounting. A similar analysis will be performed for each entity with which the Company enters into an agreement for management, servicing or related services. In performing the analysis, the Company will refer to guidance in ASC 810-10, “Consolidation.” In situations where we are the transferor of financial assets, the Company will refer to the guidance in ASC 860-10 “Transfers and Servicing.”
	In variable interest entities, (“VIEs”), an entity is subject to consolidation under ASC 810-10 if the equity investors either do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support, are unable to direct the entity’s activities or are not exposed to the entity’s losses or entitled to its residual returns. VIEs within the scope of ASC 810-10 are required to be consolidated by their 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 of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. This determination can sometimes involve complex and subjective analyses. Further, ASC 810-10 also requires ongoing assessments of whether an enterprise is the primary beneficiary of a VIE. In accordance with ASC 810-10, all transferees, including variable interest entities, must be evaluated for consolidation. If the Company were to treat securitizations as sales in the future, the Company will analyze the transactions under the guidelines of ASC 810-10 for consolidation.
	The Company may periodically enter into transactions in which it sells assets. Upon a transfer of financial assets, the Company will sometimes retain or acquire senior or subordinated interests in the related assets. Pursuant to ASC 860-10, a determination must be made as to whether a transferor has surrendered control over transferred financial assets. That determination must consider the transferor’s continuing involvement in the transferred financial asset, including all arrangements or agreements made contemporaneously with, or in contemplation of, the transfer, even if they were not entered into at the time of the transfer. The financial components approach under ASC 860-10 limits the circumstances in which a financial asset, or portion of a financial asset, should be derecognized when the transferor has not transferred the entire original financial asset to an entity that is not consolidated with the transferor in the financial statements being presented and/or when the transferor has continuing involvement with the transferred financial asset. It defines the term “participating interest” to establish specific conditions for reporting a transfer of a portion of a financial asset as a sale.
	Under ASC 860-10, after a transfer of financial assets that meets the criteria for treatment as a sale—legal isolation, ability of transferee to pledge or exchange the transferred assets without constraint and transferred control—an entity recognizes the financial and servicing assets it acquired or retained and the liabilities it has incurred, derecognizes financial assets it has sold and derecognizes liabilities when extinguished. The transferor would then determine the gain or loss on sale of financial assets by allocating the carrying value of the underlying mortgage between securities or loans sold and the interests retained based on their fair values. The gain or loss on sale is the difference between the cash proceeds from the sale and the amount allocated to the securities or loans sold. When a transfer of financial assets does not qualify for sale accounting, ASC 860-10 requires the transfer to be accounted for as a secured borrowing with a pledge of collateral.
	From time to time, the Company may securitize mortgage loans it holds if such financing is available. These transactions will be recorded in accordance with ASC 860-10 and will be accounted for as either a “sale” and the loans will be removed from the balance sheet or as a “financing” and will be classified as “real estate securities” on the consolidated balance sheet, depending upon the structure of the securitization transaction. ASC 860-10 is a complex standard that may require the Company to exercise significant judgment in determining whether a transaction should be recorded as a “sale” or a “financing.”
	Interest income recognition
	Interest income on the Company’s real estate securities portfolio is accrued based on the actual coupon rate and the outstanding principal balance of such securities. The Company has elected to record interest in accordance with ASC 835-30-35-2 using the effective interest method for all securities accounted for under the fair value option (ASC 825). As such, premiums and discounts are amortized or accreted into interest income over the lives of the securities in accordance with ASC 310-20, “Nonrefundable Fees and Other Costs,” ASC 320-10, “Investments—Debt and Equity Securities” or ASC 325-40, “Beneficial Interests in Securitized Financial Assets,” as applicable. Total interest income will flow though the interest income line item on the Consolidated Statement of Operations.
	On at least a quarterly basis for securities accounted for under ASC 320-10 and ASC 310-20 (generally Agency RMBS), prepayments of the underlying collateral must be estimated, which directly affect the speed at which we amortize such securities. If actual and anticipated cash flows differ from previous estimates, we recognize a “catch-up” adjustment in the current period to the amortization of premiums for the impact of the cumulative change in the effective yield through the reporting date.
	Similarly, we also reassess the cash flows on at least a quarterly basis for securities accounted for under ASC 325-40 (generally Non-Agency RMBS, ABS, CMBS and interest only securities). In estimating these cash flows, there are a number of assumptions that will be subject to uncertainties and contingencies. These include the rate and timing of principal and interest receipts, (including assumptions of prepayments, repurchases, defaults and liquidations), the pass-through or coupon rate and interest rate fluctuations. In addition, interest payment shortfalls due to delinquencies on the underlying mortgage loans have to be judgmentally estimated. Differences between previously estimated cash flows and current actual and anticipated cash flows are recognized prospectively through an adjustment of the yield over the remaining life of the security based on the current amortized cost of the investment as adjusted for credit impairment, if any.
	Interest income on the Company’s loan portfolio is accrued based on the actual coupon rate and the outstanding principal balance of such loans. The Company has elected to record interest in accordance with ASC 835-30-35-2 using the effective interest method for all loans accounted for under the fair value option (ASC 825). Any amortization will be reflected as an adjustment to interest income in the consolidated statements of operations.
	For investments purchased with evidence of deterioration of credit quality for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable, the Company will apply the provisions of ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” ASC 310-30 addresses accounting for differences between contractual cash flows and cash flows expected to be collected from an investor’s initial investment in loans or debt securities (loans) acquired in a transfer if those differences are attributable, at least in part, to credit quality. ASC 310-30 limits the yield that may be accreted (accretable yield) to the excess of the investor’s estimate of undiscounted expected principal, interest and other cash flows (cash flows expected at acquisition to be collected) over the investor’s initial investment in the loan. ASC 310-30 requires that the excess of contractual cash flows over cash flows expected to be collected (nonaccretable difference) not be recognized as an adjustment of yield, loss accrual or valuation allowance. Subsequent increases in cash flows expected to be collected generally should be recognized prospectively through adjustment of the loan’s yield over its remaining life. Decreases in cash flows expected to be collected should be recognized as impairment.
	The Company’s accrual of interest, discount and premium for U.S. federal and other tax purposes differs from the financial accounting treatment of these items as described above.
	Repurchase agreements
	The Company finances the acquisition of certain assets within its portfolio through the use of repurchase agreements. Repurchase agreements are treated as collateralized financing transactions and are carried at primarily their contractual amounts, including accrued interest, as specified in the respective agreements. The carrying amount of the Company’s repurchase agreements approximates fair value as the debt is short-term in nature.
	The Company pledges certain securities as collateral under repurchase agreements with financial institutions, the terms and conditions of which are negotiated on a transaction-by-transaction basis. The amounts available to be borrowed are dependent upon the fair value of the securities pledged as collateral, which fluctuates with changes in interest rates, type of security and liquidity conditions within the banking, mortgage finance and real estate industries. In response to declines in fair value of pledged securities, lenders may require the Company to post additional collateral or pay down borrowings to re-establish agreed upon collateral requirements, referred to as margin calls. As of December 31, 2013 and December 31, 2012, the Company met all margin call requirements.
	In instances where the Company acquires assets through repurchase agreements with the same counterparty from whom the assets were purchased, the Company evaluates such transactions in accordance with ASC 860-10. This standard requires the initial transfer of a financial asset and repurchase financing that are entered into contemporaneously with, or in contemplation of, one another to be considered linked unless all of the criteria found in ASC 860-10 are met at the inception of the transaction. If the transaction meets all of the conditions, the initial transfer shall be accounted for separately from the repurchase financing, and the Company will record the assets and the related financing on a gross basis on its balance sheet with the corresponding interest income and interest expense in the statements of operations. If the transaction is determined to be linked, the Company will record the initial transfer and repurchase financing on a net basis and record a forward commitment to purchase assets as a derivative instrument with changes in market value being recorded on the consolidated statement of operations. Such forward commitments are recorded at fair value with subsequent changes in fair value recognized in income. The Company refers to these transactions as Linked Transactions. When or if a transaction is no longer considered to be linked, the real estate security and related repurchase financing will be reported on a gross basis. The unlinking of a transaction causes a realized event in which the fair value of the real estate security as of the date of unlinking will become the cost basis of the real estate security. The difference between the fair value on the unlinking date and the existing cost basis of the security will be the realized gain or loss. Recognition of effective yield for such security will be calculated prospectively using the new cost basis.
	Accounting for derivative financial instruments
	The Company may enter into derivative contracts, including interest rate swaps and interest rate caps, as a means of mitigating its interest rate risk. The Company uses interest rate derivative instruments to mitigate interest rate risk rather than to enhance returns. The Company accounts for derivative financial instruments in accordance with ASC 815-10, “Derivatives and Hedging.” ASC 815-10 requires an entity to recognize all derivatives as either assets or liabilities on the balance sheet and to measure those instruments at fair value. Additionally, the fair value adjustments 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 hedge for accounting purposes and, if so, the nature of the hedging activity. As of December 31, 2013 and December 31, 2012, the Company did not have any interest rate derivatives designated as hedges. All derivatives have been recorded at fair value in accordance with ASC 820-10, with corresponding changes in value recognized in the consolidated statement of operations. The Company records derivative asset and liability positions on a gross basis.
	To-be-announced securities
	A to-be-announced security (“TBA”) is a futures contract for the purchase or sale of Agency RMBS at a predetermined price, face amount, issuer, coupon and stated maturity on an agreed-upon future date. The specific Agency RMBS delivered into or received from the contract upon the settlement date, published each month by the Securities Industry and Financial Markets Association, are not known at the time of the transaction. TBAs are exempt from ASC 815 and are accounted for under ASC 320 if there is no other way to purchase or sell that security, if delivery or receipt of that security and settlement will occur within the shortest period possible for that type of security and if it is probable at inception and throughout the term of the individual contract that physical delivery or receipt of the security will occur (referred to as the “regular-way” exception). Unrealized gains and losses associated with TBA contracts not subject to the regular-way exception or not designated as hedging instruments are recognized in the consolidated statement of operations in the line item “unrealized gain/(loss) on derivative and other instruments, net.”
	Short positions in U.S. Treasury securities through reverse repurchase agreements
	The Company may sell short U.S. Treasury securities contracts to help mitigate the potential impact of changes in interest rates. The Company may borrow securities to cover short sales of U.S. Treasury securities under reverse repurchase agreements, which are accounted for as borrowing transactions, and the Company recognizes an obligation to return the borrowed securities at fair value on its consolidated balance sheet based on the value of the underlying borrowed securities as of the reporting date. The Company establishes haircuts to ensure the market value of the underlying assets remains sufficient to protect the Company in the event of default by the counterparty. Realized and unrealized gains and losses associated with purchases and short sales of U.S. Treasury securities are recognized in “net realized gain/(loss)”, and “unrealized gain/(loss) on derivative and other instruments, net”, respectively, on our consolidated statements of operations.
	Manager compensation
	The management agreement provides for payment to the Manager of a management fee. The management fee is accrued and expensed during the period for which it is calculated and earned. For a more detailed discussion on the fees payable under the management agreement, see Note 9.
	Income taxes
	The Company conducts its operations to qualify and be taxed as a REIT. Accordingly, the Company will generally not be subject to federal or state corporate income tax to the extent that the Company makes qualifying distributions to its stockholders, and provided that it 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, it will be subject to U.S. federal, state and local income taxes and may be precluded from qualifying as a REIT for the four taxable years following the year in which the Company fails to qualify as a REIT.
	The dividends paid deduction of a REIT for qualifying dividends to its stockholders is computed using the Company’s taxable income as opposed to net income reported under GAAP in the financial statements. Taxable income, generally, will differ from net income reported on the financial statements because the determination of taxable income is based on tax provisions and not financial accounting principles.
	The Company has elected to treat certain entities including AG MIT II, LLC, AG MITT RMAT 2013, LLC, AG MITT RMAT 2013 II, LLC and AG MIT International LLC as taxable REIT subsidiaries (“TRSs”) and may elect to treat other subsidiaries as TRSs. In general, a TRS may hold assets and engage in activities that the Company cannot hold or engage in directly and generally may engage in any real estate or non-real estate-related business.
	While a domestic TRS will generate net income, a domestic TRS can declare dividends to the Company which will be included in the Company’s taxable income and necessitate a distribution to stockholders. Conversely, if the Company retains earnings at the domestic TRS level, no distribution is required and the Company can increase book equity of the consolidated entity. A domestic TRS is subject to U.S. federal, state and local corporate income taxes.
AG MIT International LLC is domiciled in Anguilla and, accordingly, taxable income generated by this foreign TRS may not be subject to local income taxation, but generally will be included in the Company’s income on a current basis as Subpart F income, whether or not distributed.
The Company’s financial results are generally not expected to reflect provisions for current or deferred income taxes, except for any activities conducted through one or more TRSs that are subject to corporate income taxation. The Company believes that it will operate in a manner that will allow it to qualify for taxation as a REIT. As a result of the Company’s expected REIT qualification, it does not generally expect to pay federal or state corporate income tax. Many of the REIT requirements, however, are highly technical and complex. If the Company were to fail to meet the REIT requirements, it would be subject to federal income taxes and applicable state and local taxes. During the year ended December 31, 2013, the Company recognized income tax expense of $3.0 million related to the income and sale of investments held within AG MITT RMAT 2013, LLC and AG MITT RMAT 2013 II, LLC. The Company did not record an income tax provision or expense as of December 31, 2012.
As a REIT, if the Company fails to distribute in any calendar year 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.
The Company evaluates uncertain income tax positions, if any, in accordance with ASC Topic 740, “Income Taxes”. The Company classifies interest and penalties, if any, related to unrecognized tax benefits as a component of provision for income taxes. See Note 9 for further details.
Stock-based compensation
The Company applies the provisions of ASC 718, “Compensation—Stock Compensation” with regard to its equity incentive plans. ASC 718 covers a wide range of share-based compensation arrangements including stock options, restricted stock plans, performance-based awards, stock appreciation rights and employee stock purchase plans. ASC 718 requires that compensation cost relating to stock-based payment transactions be recognized in financial statements. The cost is measured based on the fair value of the equity or liability instruments issued.
Compensation cost related to restricted common shares issued to the Company’s directors is measured at its estimated fair value at the grant date, and is amortized and expensed over the vesting period on a straight-line basis. Compensation cost related to restricted common shares issued to the Manager is initially measured at estimated fair value at the grant date, and is remeasured on subsequent dates to the extent the awards are unvested. The Company has elected to use the straight-line method to amortize compensation expense for the restricted common shares granted to the Manager.
Recent accounting pronouncements
In December 2011, the FASB issued Accounting Standards Updated 2011-11, “Disclosures about Offsetting Assets and Liabilities” (ASU 2011-11). ASU 2011-11 amends Topic 210 to require additional disclosure information about offsetting and related arrangements. Entities will be required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. This scope would include derivatives, sale and repurchase agreements and reverse sale and repurchase agreements. The objective of this disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of US GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards (IFRS). The guidance is effective for periods beginning on or after January 1, 2013, and interim periods within those annual periods. This disclosure was adopted and the adoption of this update did not have a material effect on the Company’s consolidated financial statements.
In January 2013, the FASB issued ASU 2013-01, “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities” (ASU 2013-1). ASU 2013-1 addresses implementation issues about ASU 2011-11 and applies to derivatives accounted for in accordance with ASC 815-10, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with ASC 210-20 “Balance Sheet – Offsetting” or ASC 815 or subject to an enforceable master netting arrangement or similar agreement. The guidance was effective January 1, 2013 and was applied retrospectively. As a result, the guidance does not have a material effect on the Company's financial statements.
In July 2013, the FASB issued ASU 2013-11, “Income Taxes” (“ASU 2013-11”). ASU 2013-11 states an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. For example, an entity should not evaluate whether the deferred tax asset expires before the statute of limitations on the tax position or whether the deferred tax asset may be used prior to the unrecognized tax benefit being settled. As a result, the guidance does not have a material effect on the Company's financial statements.

	3. Real Estate Securities
	The following tables present the current principal balance, premium or discount, amortized cost, gross unrealized gain, gross unrealized loss, fair market value, weighted average coupon rate and effective yield of the Company’s real estate securities portfolio at December 31, 2013 and December 31, 2012. The Company’s Agency RMBS are mortgage pass-through certificates or collateralized mortgage obligations representing interests in or obligations backed by pools of residential mortgage loans issued or guaranteed by Fannie Mae or Freddie Mac. The Non-Agency RMBS, ABS and CMBS portfolios are primarily not issued or guaranteed by Fannie Mae, Freddie Mac or any agency of the U.S. Government and are therefore subject to credit risk. The principal and interest payments on Agency RMBS securities have an explicit guarantee by either an agency of the U.S. government or a U.S. government-sponsored enterprise. Real estate securities that are accounted for as a component of linked transactions are not reflected in the tables set forth in this note. See Note 7 for further details.
	The following table details the real estate securities portfolio as of December 31, 2013:

	(1) We have chosen to make a fair value election pursuant to ASC 825 for our real estate securities portfolio. Unrealized gains and losses are recognized in current period earnings in the unrealized gain/(loss) on real estate securities and loans, net line item. The gross unrealized stated above represents inception to date unrealized gains/(losses).
	(2) Equity residual investments with a zero coupon rate are excluded from this calculation.
	As described in Note 2, the Company evaluates securities for 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 an investment 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 investment security before recovery of its amortized cost basis, the entire amount of the impairment loss, if any, is recognized in earnings as a realized loss and the cost basis of the security is adjusted to its fair value. For securities accounted for under ASC 325-40, “Beneficial Interests in Securitized Financial Assets,” 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 net realized gain/(loss) line item on the consolidated statement of operations.
	The following table presents the gross unrealized losses, and estimated fair value of the Company’s real estate securities by length of time that such securities have been in a continuous unrealized loss position at December 31, 2013 and December 31, 2012.
		Less than 12 months				Greater than 12 months

	31-Dec-12		777,773,600		-11,267,980		4,872,469		-2,419,978
	For the year ended December 31, 2013 the Company recognized an OTTI charge of $52.7 million, which is included in net realized gain/(loss) line item on the consolidated statement of operations. Of this amount, $48.4 million was recognized on certain securities in an unrealized loss position which the Company demonstrated intent to sell, and the charge represents a write-down to fair value as of the reporting date. Additionally, the Company recorded $4.3 million of OTTI due to an adverse change in cash flows on certain securities, where the fair values of the securities were less than their carrying amounts. No OTTI was recorded for the year ended December 31, 2012 or the period from March 7, 2011 to December 31, 2011.
	The decline in value of the remaining real estate securities is solely due to market conditions and not the quality of the assets. The investments in unrealized loss positions are not considered other than temporarily impaired because the Company currently has the ability and intent to hold the investments to maturity or for a period of time sufficient for a forecasted market price recovery up to or beyond the cost of the investments and the Company is not required to sell for regulatory or other reasons.
	All of the principal and interest payments on the Agency RMBS have an explicit guarantee by either an agency of the U.S. government or a U.S. government-sponsored enterprise.

	5. Fair Value Measurements
	As described in Note 2, the fair value of financial instruments that are recorded at fair value will be determined by the Manager, subject to oversight of the Company’s board of directors, and in accordance with ASC 820, “Fair Value Measurements and Disclosures.” When possible, the Company determines fair value using independent data sources. ASC 820 establishes a hierarchy that prioritizes the inputs to valuation techniques giving the highest priority to readily available unadjusted quoted prices in active markets for identical assets (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements) when market prices are not readily available or reliable. The three levels of the hierarchy under ASC 820 are described below:
		•	Level 1—Quoted prices in active markets for identical assets or liabilities.
		•	Level 2—Prices determined using other significant observable inputs. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk and others.
		•	Level 3—Prices 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. Unobservable inputs reflect the Company’s assumptions about the factors that market participants would use in pricing an asset or liability, and would be based on the best information available.
	Values for the Company’s securities, derivatives and loan portfolios are based upon prices obtained from third party pricing services, which are indicative of market activity. The evaluation methodology of the Company’s third-party pricing services incorporates commonly used market pricing
	methods, including a spread measurement to various indices such as the one-year constant maturity treasury and LIBOR, which are observable inputs. The evaluation also considers the underlying characteristics of each investment, which are also observable inputs, including: coupon; maturity date; loan age; reset date; collateral type; periodic and life cap; geography; and prepayment speeds. The Company collects and considers current market intelligence on all major markets, including benchmark security evaluations and bid-lists from various sources, when available. As part of the Company’s risk management process, the Company reviews and analyzes all prices obtained by comparing prices to recently completed transactions involving the same or similar investments on or near the reporting date. If, in the opinion of the Manager, one or more prices reported to the Company are not reliable or unavailable, the Manager reviews the fair value based on characteristics of the investment it receives from the issuer and available market information.
	In valuing its derivatives, 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. All of the Company’s derivatives are either subject to bilateral collateral arrangements or clearing in accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd Frank Act”). For swaps cleared under the Dodd Frank Act, a CCP now stands between the Company and its over-the-counter derivative counterparties. In order to access clearing, the Company has entered into clearing agreements with FCMs.  The Company records its derivative asset and liability positions on a gross basis.
	The Manager may also engage specialized third party valuation service providers to assess and corroborate the valuation of a selection of investments in the Company’s loan portfolio on a periodic basis. These specialized third party valuation service providers conduct independent valuation analyses based on a review of source documents, available market data, and comparable investments. The analyses provided by valuation service providers are reviewed and considered by the Manager.
	The securities underlying the Company’s linked transactions are valued using similar techniques to those used for the Company’s securities portfolio. The value of the underlying security is then netted against the carrying amount (which approximates fair value) of the repurchase agreement at the valuation date. Additionally, TBA instruments are similar in form to the Company’s Agency RMBS portfolio, and the Company therefore estimates fair value based on similar methods.
	The following table presents the Company’s financial instruments measured at fair value on a recurring basis as of December 31, 2013:

*Linked Transactions are comprised of unobservable inputs from Non-Agency RMBS and CMBS investments.
As further described above, values for the Company’s securities portfolio are based upon prices obtained from third party pricing services. Broker quotations may also be used. The significant unobservable inputs used in the fair value measurement of the Company’s Non-Agency RMBS and CMBS investments classified as a component of Linked Transactions are prepayment rates, probability of default, and loss severity in the event of default. Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the probability of default is accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumption used for prepayment rates.
Also as described above, valuation of the Company’s loan portfolio is determined by the Manager using third-party pricing services where available, and specialized third party valuation service providers. The evaluation considers the underlying characteristics of each loan, which are observable inputs, including: coupon; maturity date, loan age, reset date, collateral type, periodic and life cap, geography, and prepayment speeds. These valuations also require significant judgments, which include assumptions regarding capitalization rates, leasing, creditworthiness of major tenants, occupancy rates, availability of financing, exit plan, loan sponsorship, actions of other lenders and other factors deemed necessary by management. Changes in the market environment and other events that may occur over the life of our investments may cause the gains or losses ultimately realized on these investments to be different than the valuations currently estimated. Analyses provided by valuation service providers are reviewed and considered by the Manager.

Disclosure Of Repurchase Agreements [Abstract]	'
Repurchase Agreements, Resale Agreements, Securities Borrowed, and Securities Loaned Disclosure [Text Block]	'
	6. Repurchase Agreements
	The Company pledges certain real estate securities as collateral under repurchase agreements with financial institutions, the terms and conditions of which are negotiated on a transaction-by-transaction basis. Repurchase agreements involve the sale and a simultaneous agreement to repurchase the transferred assets or similar assets at a future date. The amount borrowed generally is equal to the fair value of the assets pledged less an agreed-upon discount, referred to as a “haircut.” Repurchase agreements entered into by the Company are accounted for as financings and require the repurchase of the transferred securities at the end of each agreement’s term, typically 30 to 90 days. The carrying amount of the Company’s repurchase agreements approximates fair value as the debt is short-term in nature. The Company maintains the beneficial interest in the specific securities pledged during the term of the repurchase agreement and receives the related principal and interest payments. Interest rates on these borrowings are fixed based on prevailing rates corresponding to the terms of the borrowings, and interest is paid at the termination of the repurchase agreement at which time the Company may enter into a new repurchase agreement at prevailing market rates with the same counterparty or repay that counterparty and negotiate financing with a different counterparty. In response to declines in fair value of pledged securities due to changes in market conditions or the publishing of monthly security paydown factors, lenders typically require 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, referred to as margin calls. Under the terms of the Company’s master repurchase agreements, the counterparties may, in certain cases, sell or re-hypothecate the pledged collateral.
	The following table presents certain information regarding the Company’s repurchase agreements as of December 31, 2013:
	Repurchase Agreements Maturing Within:	Balance		Weighted		Weighted Average
				Average Rate		Haircut
	30 days or less	$	1,357,768,314	0.85	%	7.97	%

	Repurchase Agreements	Balance		Weighted		Weighted Average
	Maturing Within:			Average Rate		Haircut
	30 days or less	$	2,242,856,547	0.71	%	7.28	%

	Total / Weighted Average	$	3,911,419,818	0.7	%	6.5	%
	Although repurchase agreements are committed borrowings until maturity, the lender retains the right to mark the underlying collateral to fair value. A reduction in the value of pledged assets resulting from changes in market conditions or factor changes would require the Company to provide additional collateral or cash to fund margin calls. The following table presents information with respect to the Company’s posting of collateral at December 31, 2013 and December 31, 2012:
		December 31, 2013		December 31, 2012

	The Company seeks to transact with several different counterparties in order to reduce the exposure to any single counterparty. The Company has entered into master repurchase agreements (“MRAs”) with 30 counterparties, under which the Company had outstanding debt with 24 and 29 counterparties at December 31, 2013 and December 31, 2012, respectively. At December 31, 2013, the following table reflects amounts at risk under the Company’s repurchase agreements greater than 5% of its equity with any counterparty, excluding linked transactions.
	Counterparty	Amount at Risk		Weighted		Percentage of

	In addition to the amount at risk in the table above, at December 31, 2013, the Company had repurchase agreements with Credit Suisse determined to be linked. The amount at risk including linked transactions to Credit Suisse is $72.1 million, with a weighted average maturity of 30 days, representing approximately 10.2% of stockholders’ equity.
	At December 31, 2012, the following table reflects amounts at risk under its repurchase agreements greater than 5% of the Company’s equity with any counterparty, excluding linked transactions.

	On April 9, 2012, AG MIT, LLC (“AG MIT”), a direct, wholly-owned subsidiary of the Company, entered into a Master Repurchase and Securities Contract (the “Repurchase Agreement”) with Wells Fargo Bank, National Association to finance the Company’s acquisition of certain residential, Non-Agency RMBSs. Effective April 12, 2013, AG MIT entered into an Amended and Restated Master Repurchase and Securities Contract (the “Renewal Agreement”) to the Repurchase Agreement dated as of April 9, 2012. The Renewal Agreement was entered into for multiple purposes, including the amendment of the Repurchase Agreement to finance AG MIT’s acquisition of not only residential, non-Agency Securities, but also certain consumer asset-backed securities and commercial mortgage-backed securities. Each transaction under the Renewal Agreement will also have its own specific terms, such as identification of the assets subject to the transaction, sale price, repurchase price and rate. The Renewal Agreement increases the aggregate maximum borrowing capacity of the Repurchase Agreement from $75 million to $125 million and extends the maturity date from April 8, 2013 to April 11, 2014. The Renewal Agreement also includes the same provisions in the Repurchase Agreement permitting the maturity date to be extended for an additional 90 days.  As of December 31, 2013 and December 31, 2012, the Company had $106.5 million and $75.0 million, respectively, of debt outstanding under the Repurchase Agreement.
	The Renewal Agreement contains representations, warranties, covenants, events of default and indemnities that are substantially identical to those in the Repurchase Agreement and are customary for agreements of this type. The Renewal Agreement also contains amended financial covenants that require, as of the last business day of each quarter and on any funding date, the Company and AG MIT to maintain (i) their Total Indebtedness to their Adjusted Tangible Net Worth at a ratio less than the Leverage Ratio; (ii) an Adjusted Tangible Net Worth of not less than $430 million; and (iii) at all times, Liquidity of not less than $30 million and unrestricted cash of not less than $5 million.
	As discussed in Note 2, for any transactions determined to be linked, the initial transfer and repurchase financing will be recorded as a forward commitment to purchase assets. At December 31, 2013 and December 31, 2012, the Company had repurchase agreements of $222.8 million and $282.3 million, respectively, that were accounted for as linked. These linked repurchase agreements are not included in the above tables. See Note 7 for details.

Interest Rate Swaps
To help mitigate exposure to higher short-term interest rates, the Company uses currently-paying and forward-starting, one- and three-month LIBOR-indexed, pay-fixed, receive-variable,  interest rate swap agreements. This arrangement establishes a relatively stable fixed rate on related borrowings because the variable-rate payments received on the swap agreements largely offset interest accruing on the related borrowings, leaving the fixed-rate payments to be paid on the swap agreements as the Company’s effective borrowing rate, subject to certain adjustments including changes in spreads between variable rates on the swap agreements and actual borrowing rates.
The following table presents information about the Company’s interest rate swaps as of December 31, 2013:

TBAs
The Company has entered into TBA positions to facilitate the future purchase or sale of specified Agency RMBS. Pursuant to these TBAs, the Company agrees to purchase or sell, for future delivery or receipt, Agency RMBS with certain principal and interest terms and certain types of underlying collateral, but the particular Agency RMBS to be delivered or received would not be identified until shortly, generally two days, before the TBA settlement date. The Company records TBA purchases and sales on the trade date and presents the purchase or sale net of the corresponding payable or receivable until the settlement date of the transaction. Contracts for the purchase or sale of specified Agency RMBS are accounted for as derivatives if the delivery of the specified Agency security and settlement extends beyond the shortest period possible for that type of security.
The following table presents information about the Company’s TBAs for the years ended December 31, 2013 and December 31, 2012:

Linked Transactions
As discussed in Note 2, when the initial transfer of a financial asset and repurchase financing are entered into contemporaneously with, or in contemplation of, one another, the transaction will be considered linked unless all of the criteria found in ASC 860-10 are met at the inception of the transaction. If the transaction is determined to be linked, the Company will record the initial transfer and repurchase financing on a net basis and record a forward commitment to purchase assets as a derivative instrument. Changes in market value are recorded together with net interest income in the “Income/(loss) from linked transactions, net” line item on the consolidated statement of operations. When, or if a transaction is no longer considered linked, the security and related repurchase agreement will be recorded on a gross basis. The fair value of linked transactions reflects the value of the underlying security’s fair market value netted with the respective linked repurchase agreement borrowings and net accrued interest.
Certain of the Company’s linked transactions became unlinked during the periods presented. For the year ended December 31, 2013 Non-Agency RMBS with security fair values of $141.6 million, and related repurchase agreement borrowings of $118.8 million, were unlinked, and the Company recorded a net realized loss of $4.0 million, from the unlinking of the linked transactions. For the year ended December 31, 2012, Non-Agency RMBS and CMBS with a fair value of $161.7 million and $45.3 million, respectively, and related repurchase agreement borrowings secured by Non-Agency RMBS and CMBS of $131.7 million and $37.2 million, respectively, were unlinked, and the Company recorded net realized gains of $3.4 million, from the unlinking of the Linked Transactions. No transactions became unlinked for the period ended December 31, 2011.

	8. Earnings per Share
	Basic earnings per share (“EPS”) is calculated by dividing net income/(loss) available to common stockholders for the period by the weighted- average shares of the Company’s common stock outstanding for that period that participate in dividends. Diluted EPS takes into account the effect of dilutive instruments, such as stock options, warrants and unvested restricted stock, but uses the average share price for the period in determining the number of incremental shares that are to be added to the weighted-average number of shares outstanding.
	As of December 31, 2013 and December 31, 2012, the Company’s outstanding warrants and unvested shares of restricted common stock were as follows:
		December 31, 2013			December 31, 2012			December 31, 2011
	Warrants		1,007,500			1,642,000			3,205,000
	Restricted stock granted to the Manager		10,064			23,480			40,250
	Restricted stock granted to the independent directors		2,500			4,000			6,000
	Each warrant entitles the holder to purchase half a share of the Company’s common stock at a fixed price upon exercise of the warrant.   For the year ended December 31, 2013 and the period ended December 31, 2011, the Company assumed that no warrants would be exercised as the weighted average market value per share of the Company’s common stock was below the strike price of the warrants, and the warrants were therefore not included in the Company’s diluted weighted average shares outstanding. During the year ended December 31, 2012, the average market value per share of the Company’s common stock was above the exercise price of the warrants, and therefore the warrants were included in the Company’s diluted weighted average shares outstanding in accordance with ASC 260.  Shares of restricted stock held by the Manager and independent directors accrue dividends but are not paid until vested and are therefore not considered to be participating shares. The dilutive effects of restricted stock are included in diluted weighted average shares outstanding for the year ended December 31, 2012 and the period ended December 31, 2011. Excluded from the computation of diluted earnings per share because their effect would be anti-dilutive were both Manager and director restricted stock and warrants of 46,052 for the year ended December 31, 2013.
	The following table presents a reconciliation of the earnings and shares used in calculating basic and diluted EPS for the years ended December 31, 2013 and 2012 and for the period from March 7, 2011 to December 31, 2011:

	9. 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 provided it satisfies on a continuing basis, through actual investment and operating results, the REIT requirements including certain asset, income, distribution and stock ownership tests. Most states follow U.S. federal income tax treatment of REITs.
	For the years ended December 31, 2013 and 2012 and the period ended December 31, 2011, the Company elected to satisfy the REIT distribution requirements in part with a dividend to be paid in 2014, 2013 and 2012, respectively. In conjunction with this, the Company accrued an excise tax of $1.5  million, $1.7 million and $0.1 million, respectively, which is included in the excise tax line item on the accompanying consolidated statements of operations.
	The Company files tax returns in several U.S jurisdictions. There are no ongoing U.S. federal, state and local tax examinations
	The Company has elected to treat certain entities, including AG MIT II, LLC, AG MITT RMAT 2013, LLC, AG MITT RMAT 2013 II, LLC and AG MIT International LLC as TRSs and may elect to treat other subsidiaries as TRSs. In general, a TRS may hold assets and engage in activities that the Company cannot hold or engage in directly, and generally may engage in any real estate or non-real estate-related business.
	A domestic TRS is subject to federal, state and local corporate income taxes. During the year ended December 31, 2013, the Company recognized an income tax expense of $3.0 million related to the income and sale of investments held within AG MITT RMAT 2013, LLC and AG MITT RMAT 2013 II, LLC. The Company did not record an income tax provision as of December 31, 2013. The Company did not record an income tax provision or expense for the year ended December 31, 2012 and for the period ended December 31, 2011.
	AG MIT International LLC is domiciled in Anguilla and, accordingly, taxable income generated by this foreign TRS may not be subject to local income taxation, but generally will be included in the Company’s income on a current basis as Subpart F income, whether or not distributed.
	Cash distributions declared by the Company that do not exceed its current or accumulated earnings and profits will be considered ordinary income to stockholders for income tax purposes unless all or a portion of a distribution is designated by the Company as a capital gain dividend.  Distributions in excess of the Company’s current and accumulated earnings and profits will be characterized as return of capital or capital gains. For the period ended December 31, 2013, all income distributed was in the form of common and preferred dividends and were characterized as ordinary income. For the year ended December 31, 2012, 13.51% of income distributed in the form of common and preferred dividends has been characterized as capital gains and 86.49% has been characterized as ordinary income. For the period ended December 31, 2011, all income distributed was in the form of common dividends and were characterized as ordinary income.
	Based on the Company’s analysis of any potential uncertain income tax positions, the Company concluded it did not have any uncertain tax positions that meet the recognition or measurement criteria of ASC 740 as of December 31, 2013, 2012 or 2011. The Company’s federal income tax return for the last three tax years is open to examination by the IRS. In the event that the Company incurs income tax related interest and penalties, its policy is to classify them as a component of provision for income taxes

For purposes of calculating the management fee, “Stockholders’ Equity” means the sum of the net proceeds from any issuances of equity securities (including preferred securities) since inception (allocated on a pro rata daily basis for such issuances during the fiscal quarter of any such issuance, and excluding any future equity issuance to the Manager), plus the Company’s retained earnings at the end of such quarter (without taking into account any non-cash equity compensation expense or other non-cash items described below incurred in current or prior periods), less any amount that the Company pays for repurchases of its common stock, excluding any unrealized gains, losses or other non-cash items that have impacted stockholders’ equity as reported in the Company’s 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. Stockholders’ Equity, for purposes of calculating the management fee, could be greater or less than the amount of stockholders’ equity shown on the Company’s financial statements.
	For the years ended December 31, 2013 and December 31, 2012 and for the period ended December 31, 2011, the Company incurred management fees of $10.7 million, $6.4 million and $1.5 million, respectively.
	Termination fee
	The termination fee, payable for the Company’s termination of the management agreement without cause or the Manager’s termination of the management agreement upon a default in the performance of any material term of the management agreement, will be equal to three times the average annual management fee during the 24-month period prior to such termination, calculated as of the end of the most recently completed fiscal quarter.  As of December 31, 2013, no event of termination of the management agreement had occurred.
	Expense reimbursement
	The Company is required to reimburse the Manager for operating expenses related to the Company that are incurred by the Manager, including expenses relating to legal, accounting, due diligence and other services. The Company’s reimbursement obligation is not subject to any dollar limitation. The Company will not reimburse the Manager for the salaries and other compensation of its personnel except that the Company will be responsible for expenses incurred by the Manager in employing the Company’s chief financial officer, general counsel and other employees as further described below.
	The Company will reimburse the Manager or its affiliates for the allocable share of the compensation, including, without limitation, annual base salary, bonus, any related withholding taxes and employee benefits paid to (i) the Company’s chief financial officer based on the percentage of his time spent on Company affairs, (ii) the Company’s general counsel based on the percentage of his time spent on the Company’s affairs, and (iii) other corporate finance, tax, accounting, internal audit, legal, risk management, operations, compliance and other non-investment personnel of the Manager and its affiliates who spend all or a portion of their time managing the Company’s affairs based upon the percentage of time devoted by such personnel to the Company’s affairs. In their capacities as officers or personnel of the Manager or its affiliates, they will devote such portion of their time to the Company’s affairs as is necessary to enable the Company to operate its business. For the year ended December 31, 2013, the Company expensed in to Other operating expenses $6.5 million of reimbursable expenses payable to the Manager. For the year ended December 31, 2012 and for the period ended December 31, 2011, the Company expensed into Other operating expenses $2.2 million and $0.0 million, respectively, of reimbursable expenses payable to the Manager.  To facilitate the ramp-up and establishment of the Company, the Manager waived its right to receive $2.2 million and $1.9 million of expense reimbursement for the year ended December 31, 2012 and the period ended December 31, 2011, respectively.
	Restricted stock grants
	On July 6, 2011 (the date of consummation of the IPO), the Company entered into (i) a restricted stock award agreement with the Manager under the Manager Equity Incentive Plan, pursuant to which the Manager received 40,250 shares of the Company’s common stock, which vest ratably on a quarterly basis over a three-year period that began on October 1, 2011 and (ii) restricted stock award agreements with the Company’s four initial independent directors under the Equity Incentive Plan, pursuant to which each of the four initial independent directors received 1,500 shares of the Company’s common stock that vest in equal installments over three years on each annual anniversary of the grant date. Following the election of the fifth independent director at the 2013 Annual Meeting of Stockholders, 500 shares of the Company’s common stock were granted on June 1, 2013 to the fifth independent director under the Equity Incentive Plan. These shares will vest on July 6, 2014.
	Pursuant to the Manager Equity Incentive Plan and the Equity Incentive Plan, 277,500 shares of common stock are available to be awarded.  Awards under the equity incentive plans are forfeitable until they become vested. An award will become vested only if the vesting conditions set forth in the award agreement (as determined by the board of directors or the compensation committee, as applicable) are satisfied. The vesting conditions may include performance of services for a specified period, achievement of performance goal, or a combination of both. The board of directors or the compensation committee, as applicable, also has authority to provide for accelerated vesting upon the occurrence of certain events.
	During 2013, the Company paid a $60,000 annual base director’s fee to each independent director. With respect to the fifth independent director elected at the 2013 Annual Meeting of Stockholders, the annual base director’s fee for 2013 will be prorated for the period of May 1, 2013 to December 31, 2013. Base director’s fees are paid 50% in cash and 50% in restricted common stock. The number of shares of restricted common stock to be issued each quarter to each independent director is determined based on the fair market value of the Company’s common stock equal to the closing price thereof on the New York Stock Exchange on the last business day of each fiscal quarter. To the extent that any fractional shares would otherwise be issuable and payable to each independent director, a cash payment is made to each independent director in lieu of any fractional shares. All directors’ fees are paid pro rata (and restricted stock grants determined) on a quarterly basis in arrears, and shares issued are fully vested and non-forfeitable. These shares may not be sold or transferred during the time of service as an independent member of the Company’s board.

	11. Equity
	On June 29, 2011, the Company entered into (i) a binding underwriting agreement with a group of underwriters to sell 5,500,000 shares of the Company’s common stock for $20.00 per share for an aggregate offering price of $110.0 million, (ii) a unit purchase agreement with the purchasers of units in a concurrent private placement to purchase 3,205,000 units at $20.00 per share, (iii) stock purchase agreements with AG Funds and two of the Company’s officers, to purchase in the aggregate 500,000 private placement shares of the Company’s common stock at $20.00 per share, (iv) a registration rights agreement with the purchasers of units in the private placement, AG Funds and two of its officers, and (v) an agreement with the Manager pursuant to which the Manager is entitled to receive a management fee and the reimbursement of certain expenses. See Note 9 for further detail on the management fee and expense reimbursement. The issuance of shares and subsequent receipt of cash related to the IPO and concurrent private placement were recorded upon settlement of the offering.
	The Company completed its IPO and concurrent private placement on July 6, 2011, at which time all subscriptions were paid in cash and the Company issued 9,205,000 shares of common stock. Net proceeds to the Company were $182.3 million, net of issuance costs borne by the Company of approximately $1.8 million. As detailed below, on July 20, 2011, the underwriters exercised in part their over-allotment option to purchase 800,000 shares of the Company’s common stock at $20.00 per share. After such exercise, net proceeds to the Company increased to $198.1 million, net of total issuance costs borne by the Company of approximately $2.0 million. The Company’s obligation to pay for the expenses incurred in connection with its formation, the IPO and the concurrent private placement was capped at 1% of the total gross proceeds from the offering and concurrent private placement (or approximately $1.8 million, increasing to approximately $2.0 million when the underwriters exercised their overallotment option). The Manager paid the expenses incurred above this 1% cap. Additionally, the Manager agreed to pay the entire underwriting discount; therefore, no underwriting discount was borne by the Company.
	On July 6, 2011, the Company entered into (i) warrant agreements with the purchasers of 3,205,000 units in the private placement, (ii) a restricted stock award agreement with the Company’s Manager under the Manager Equity Incentive Plan, pursuant to which the Manager received 40,250 shares of the Company’s common stock, and (iii) restricted stock award agreements with the Company’s independent directors under the Equity Incentive Plan, pursuant to which each of the independent directors received 1,500 shares of the Company’s common stock.
	On July 20, 2011, pursuant to the terms of the underwriting agreement, dated June 29, 2011, between the Company, the Manager, Angelo, Gordon and Deutsche Bank Securities Inc., as representative of the several underwriters (the “Underwriters”), the Underwriters exercised in part their over-allotment option to purchase 800,000 shares of the Company’s common stock (the “Additional Shares”) at $20.00 per share. The over-allotment option to purchase up to an additional 825,000 shares of the Company’s common stock was granted in connection with the Company’s IPO of 5.5 million shares. The Company received proceeds of $16.0 million from the sale of the Additional Shares. At the completion of the offering, after giving effect to the partial exercise of the over-allotment option and the private placement, the Company sold a total of 10,005,000 shares of common stock and raised approximately $198.1 million in net proceeds.
	Concurrently with the IPO, the Company offered a private placement of 3,205,000 units at $20.00 per share to a limited number of investors qualifying as “accredited investors” under Rule 501 of Regulation D promulgated under the Securities Act of 1933, as amended (the “Securities Act”). Each unit consisted of one share of common stock (“private placement share”) and a warrant (“private placement warrant”) to purchase 0.5 of a share of common stock. Each private placement warrant had an exercise price of $20.50 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like), and was exercised as described below. The private placement shares and private placement warrants were immediately separated and were issued separately, but were purchased together in the private placement. Total proceeds from the private placement were $74.1 million, including 500,000 private placement shares sold to AG Funds and two of the Company’s officers.
	The Company’s independent directors entered into a lock-up agreement under which they have agreed, subject to the terms and conditions of the lock-up agreement, not to sell the private placement shares, warrants or the shares of the Company’s common stock issuable upon exercise of the private placement warrants, which the Company refers to as the warrant shares, for 180 days from the closing of the private placement. AG Funds and two of the Company’s officers entered into a lock-up agreement under which they agreed, subject to the terms and conditions of the lock-up agreement, not to sell the private placement shares, warrants or warrant shares for two years from the closing of the private placement.
	On January 24, 2012, the Company completed a follow-on offering of 5,000,000 shares of its common stock and subsequently issued an additional 750,000 shares of common stock pursuant to the underwriters’ over-allotment option at a price of $19.00 per share for aggregate gross proceeds of approximately $109.3 million.

The Company received total gross proceeds of approximately $51.8 million. Net proceeds to the Company from the offering were approximately $49.9 million, net of underwriting discounts, commissions and expenses.

	14. Subsequent Events
	On February 18, 2014, AG MIT WFB1, a direct, wholly-owned subsidiary of the Company, entered into the WFB1 Repurchase Agreement, with Wells Fargo to finance AG MIT WFB1’s acquisition of certain beneficial interests in trusts owning participation interests in one or more pools of residential mortgage loans. Each transaction under the WFB1 Repurchase Agreement will have its own specific terms, such as identification of the assets subject to the transaction, sale price, repurchase price and rate. The WFB1 Repurchase Agreement provides for a funding period ending February 10, 2015 and a facility termination date of February 9, 2016. The maximum aggregate borrowing capacity available under the WFB1 Repurchase Agreement is $100 million.  At the request of AG MIT WFB1, Wells Fargo may grant a one year extension of the facility termination date.
	The WFB1 Repurchase Agreement contains representations, warranties, covenants, events of default and indemnities that are customary for agreements of this type. The WFB1 Repurchase Agreement also contains financial covenants that require, as of the last business day of each quarter and on any funding date, the Company and AG MIT WFB1 to maintain (i) their Total Indebtedness to their Adjusted Tangible Net Worth at a ratio less than the Leverage Ratio; (ii) an Adjusted Tangible Net Worth of not less than $430 million; and (iii) at all times, Liquidity of not less than $30 million and unrestricted cash of not less than $5 million.

	Dec. 31, 2013
Accounting Policies [Abstract]	'
Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Cash and cash equivalents
	Cash is comprised of cash on deposit with financial institutions. We classify highly liquid investments with original maturities of three months or less from the date of purchase as cash equivalents. We place our cash and cash equivalents with high credit quality institutions to minimize credit risk exposure. Any cash held by the Company as collateral would be included in a due to broker line item on the consolidated balance sheet and in cash flows from financing activities on the consolidated statement of cash flows.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Restricted cash
	Restricted cash includes cash pledged as collateral for clearing and executing trades, interest rate swaps and repurchase agreements. Restricted cash is carried at cost, which approximates fair value.
Offering and Organization Costs [Policy Text Block]	'
	Offering and organization costs
	The Company incurred offering and organization costs in connection with arranging the Company’s initial public offering (“IPO”), subsequent follow-on offerings of its common stock and issuances of preferred stock. The offering and other organization costs were paid out of the proceeds of the respective offerings. Offering costs in connection with the common stock offerings have been accounted for as a reduction of additional paid-in-capital. Offering costs in connection with preferred stock offerings have been accounted for as a reduction of their respective gross proceeds. Costs incurred to organize the Company have been expensed as incurred. The Company’s obligation to pay for organization and offering expenses incurred in connection with its IPO was capped at 1% of the total gross proceeds from the IPO and the concurrent private placement, and the Manager paid for such expenses incurred above the cap. See Note 9 for further details.
Use of Estimates, Policy [Policy Text Block]	'
	Use of estimates
	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results may differ from those estimates.
Earnings Per Share, Policy [Policy Text Block]	'
	Earnings/(Loss) per share
	In accordance with the provisions of Accounting Standards Codification (“ASC”) 260, “Earnings per Share,” the Company calculates basic income/(loss) per share by dividing net income/(loss) available to common stockholders for the period by weighted-average shares of the Company’s common stock outstanding for that period. Diluted income/(loss) per share takes into account the effect of dilutive instruments, such as stock options, warrants and unvested restricted stock, but uses the average share price for the period in determining the number of incremental shares that are to be added to the weighted-average number of shares outstanding.
Fair Value of Financial Instruments, Policy [Policy Text Block]	'
	Valuation of financial instruments
	The fair value of the financial instruments that the Company records at fair value will be determined by the Manager, subject to oversight of the Company’s board of directors, and in accordance with ASC 820, “Fair Value Measurements and Disclosures.” When possible, the Company determines fair value using independent data sources. ASC 820 establishes a hierarchy that prioritizes the inputs to valuation techniques giving the highest priority to readily available unadjusted quoted prices in active markets for identical assets (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements) when market prices are not readily available or reliable. The three levels of the hierarchy under ASC 820 are described below:
		•	Level 1—Quoted prices in active markets for identical assets or liabilities.
		•	Level 2—Prices determined using other significant observable inputs. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk and others.
		•	Level 3—Prices 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. Unobservable inputs reflect the Company’s assumptions about the factors that market participants would use in pricing an asset or liability, and would be based on the best information available.
	Transfers between levels are assumed to occur at the beginning of the reporting period.
Real Estate, Policy [Policy Text Block]	'
	Accounting for real estate securities
	Investments in real estate securities are recorded in accordance with ASC 320. The Company has chosen to make a fair value election pursuant to ASC 825 for its real estate securities portfolio. The real estate securities are recorded at fair market value on the consolidated balance sheet and the periodic change in fair market value is recorded in current period earnings on the consolidated statement of operations as a component of “Unrealized gain/(loss) on real estate securities and loans, net.”
	These investments generally meet the requirements to be classified as available for sale under ASC 320-10-25, “Debt and Equity Securities”, which requires the securities to be carried at fair value on the consolidated balance sheet with changes in fair value charged to other comprehensive income, a component of stockholders’ equity. Electing the fair value option allows the Company to record changes in fair value in the statement of operations, which, in management’s view, more appropriately reflects the results of our operations for a particular reporting period as all securities activities will be recorded in a similar manner.
	The Company 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 an investment 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 investment security before recovery of its amortized cost basis, the entire amount of the impairment loss, if any, is recognized in earnings as a realized loss and the cost basis of the security is adjusted to its fair value. For securities accounted for under ASC 325-40, “Beneficial Interests in Securitized Financial Assets,” 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 net realized gain/(loss) line item on the consolidated statement of operations.
	Increases in interest income may be recognized on a security that an OTTI charge was taken, if the performance of such security subsequently improves. 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.
	Securities in an unrealized loss position at December 31, 2013 are not considered other than temporarily impaired as the Company has 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 cost of the investment, and the Company is not required to sell the security for regulatory or other reasons. See Note 3 for a summary of OTTI charges recorded.
Marketable Securities, Available-for-sale Securities, Policy [Policy Text Block]	'
	Sales of securities
	Sales of securities are driven by the Manager’s portfolio management process. The Manager seeks to mitigate risks including those associated with prepayments and will opportunistically rotate the portfolio into securities with 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 securities and derivatives, inclusive of securities accounted for as a component of linked transactions are included in the net realized gain/(loss) line item on the consolidated statement of operations. The cost of positions sold is calculated using a first in, first out, or FIFO, basis. Realized gains and losses are recorded in earnings at the time of disposition.
Accounting For Loans [Policy Text Block]	'
	Accounting for loans
	Investments in mortgage loans are recorded in accordance with ASC 310. The Company has chosen to make a fair value election pursuant to ASC 825 for its loan portfolio. Loans are recorded at fair market value on the consolidated balance sheet and any periodic change in fair market value will be recorded in current period earnings on the consolidated statement of operations as a component of “Unrealized gain/(loss) on real estate securities and loans, net.”
	The Company amortizes or accretes any premium or discount over the life of the related loan utilizing the effective interest method. 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 they are 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 amount of the loss accrual is calculated and recorded accordingly. 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.
Investments In and Advances To Affiliates Schedule Of Investments [Policy Text Block]	'
	Investment in affiliates
	The Company’s unconsolidated ownership interests in affiliates are generally accounted for using the equity method. The underlying entities have chosen to make a fair value election pursuant to ASC 825; as such the Company will treat its investment in affiliates consistently with this election. The investment in affiliates is recorded at fair market value on the consolidated balance sheet and periodic changes in fair market value will be recorded in current period earnings on the consolidated statement of operation as a component of “Equity in earnings from affiliate.” Capital contributions, distributions and profits and losses of such entities are allocated in accordance with the terms of the applicable agreements.
Investment, Policy [Policy Text Block]	'
	Investment consolidation
	For each investment made, the Company evaluates the underlying entity that issued the securities acquired or to which the Company makes a loan to determine the appropriate accounting. A similar analysis will be performed for each entity with which the Company enters into an agreement for management, servicing or related services. In performing the analysis, the Company will refer to guidance in ASC 810-10, “Consolidation.” In situations where we are the transferor of financial assets, the Company will refer to the guidance in ASC 860-10 “Transfers and Servicing.”
	In variable interest entities, (“VIEs”), an entity is subject to consolidation under ASC 810-10 if the equity investors either do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support, are unable to direct the entity’s activities or are not exposed to the entity’s losses or entitled to its residual returns. VIEs within the scope of ASC 810-10 are required to be consolidated by their 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 of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. This determination can sometimes involve complex and subjective analyses. Further, ASC 810-10 also requires ongoing assessments of whether an enterprise is the primary beneficiary of a VIE. In accordance with ASC 810-10, all transferees, including variable interest entities, must be evaluated for consolidation. If the Company were to treat securitizations as sales in the future, the Company will analyze the transactions under the guidelines of ASC 810-10 for consolidation.
	The Company may periodically enter into transactions in which it sells assets. Upon a transfer of financial assets, the Company will sometimes retain or acquire senior or subordinated interests in the related assets. Pursuant to ASC 860-10, a determination must be made as to whether a transferor has surrendered control over transferred financial assets. That determination must consider the transferor’s continuing involvement in the transferred financial asset, including all arrangements or agreements made contemporaneously with, or in contemplation of, the transfer, even if they were not entered into at the time of the transfer. The financial components approach under ASC 860-10 limits the circumstances in which a financial asset, or portion of a financial asset, should be derecognized when the transferor has not transferred the entire original financial asset to an entity that is not consolidated with the transferor in the financial statements being presented and/or when the transferor has continuing involvement with the transferred financial asset. It defines the term “participating interest” to establish specific conditions for reporting a transfer of a portion of a financial asset as a sale.
	Under ASC 860-10, after a transfer of financial assets that meets the criteria for treatment as a sale—legal isolation, ability of transferee to pledge or exchange the transferred assets without constraint and transferred control—an entity recognizes the financial and servicing assets it acquired or retained and the liabilities it has incurred, derecognizes financial assets it has sold and derecognizes liabilities when extinguished. The transferor would then determine the gain or loss on sale of financial assets by allocating the carrying value of the underlying mortgage between securities or loans sold and the interests retained based on their fair values. The gain or loss on sale is the difference between the cash proceeds from the sale and the amount allocated to the securities or loans sold. When a transfer of financial assets does not qualify for sale accounting, ASC 860-10 requires the transfer to be accounted for as a secured borrowing with a pledge of collateral.
	From time to time, the Company may securitize mortgage loans it holds if such financing is available. These transactions will be recorded in accordance with ASC 860-10 and will be accounted for as either a “sale” and the loans will be removed from the balance sheet or as a “financing” and will be classified as “real estate securities” on the consolidated balance sheet, depending upon the structure of the securitization transaction. ASC 860-10 is a complex standard that may require the Company to exercise significant judgment in determining whether a transaction should be recorded as a “sale” or a “financing.”
Revenue Recognition, Policy [Policy Text Block]	'
	Interest income recognition
	Interest income on the Company’s real estate securities portfolio is accrued based on the actual coupon rate and the outstanding principal balance of such securities. The Company has elected to record interest in accordance with ASC 835-30-35-2 using the effective interest method for all securities accounted for under the fair value option (ASC 825). As such, premiums and discounts are amortized or accreted into interest income over the lives of the securities in accordance with ASC 310-20, “Nonrefundable Fees and Other Costs,” ASC 320-10, “Investments—Debt and Equity Securities” or ASC 325-40, “Beneficial Interests in Securitized Financial Assets,” as applicable. Total interest income will flow though the interest income line item on the Consolidated Statement of Operations.
	On at least a quarterly basis for securities accounted for under ASC 320-10 and ASC 310-20 (generally Agency RMBS), prepayments of the underlying collateral must be estimated, which directly affect the speed at which we amortize such securities. If actual and anticipated cash flows differ from previous estimates, we recognize a “catch-up” adjustment in the current period to the amortization of premiums for the impact of the cumulative change in the effective yield through the reporting date.
	Similarly, we also reassess the cash flows on at least a quarterly basis for securities accounted for under ASC 325-40 (generally Non-Agency RMBS, ABS, CMBS and interest only securities). In estimating these cash flows, there are a number of assumptions that will be subject to uncertainties and contingencies. These include the rate and timing of principal and interest receipts, (including assumptions of prepayments, repurchases, defaults and liquidations), the pass-through or coupon rate and interest rate fluctuations. In addition, interest payment shortfalls due to delinquencies on the underlying mortgage loans have to be judgmentally estimated. Differences between previously estimated cash flows and current actual and anticipated cash flows are recognized prospectively through an adjustment of the yield over the remaining life of the security based on the current amortized cost of the investment as adjusted for credit impairment, if any.
	Interest income on the Company’s loan portfolio is accrued based on the actual coupon rate and the outstanding principal balance of such loans. The Company has elected to record interest in accordance with ASC 835-30-35-2 using the effective interest method for all loans accounted for under the fair value option (ASC 825). Any amortization will be reflected as an adjustment to interest income in the consolidated statements of operations.
	For investments purchased with evidence of deterioration of credit quality for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable, the Company will apply the provisions of ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” ASC 310-30 addresses accounting for differences between contractual cash flows and cash flows expected to be collected from an investor’s initial investment in loans or debt securities (loans) acquired in a transfer if those differences are attributable, at least in part, to credit quality. ASC 310-30 limits the yield that may be accreted (accretable yield) to the excess of the investor’s estimate of undiscounted expected principal, interest and other cash flows (cash flows expected at acquisition to be collected) over the investor’s initial investment in the loan. ASC 310-30 requires that the excess of contractual cash flows over cash flows expected to be collected (nonaccretable difference) not be recognized as an adjustment of yield, loss accrual or valuation allowance. Subsequent increases in cash flows expected to be collected generally should be recognized prospectively through adjustment of the loan’s yield over its remaining life. Decreases in cash flows expected to be collected should be recognized as impairment.
	The Company’s accrual of interest, discount and premium for U.S. federal and other tax purposes differs from the financial accounting treatment of these items as described above.
Repurchase Agreements, Valuation, Policy [Policy Text Block]	'
	Repurchase agreements
	The Company finances the acquisition of certain assets within its portfolio through the use of repurchase agreements. Repurchase agreements are treated as collateralized financing transactions and are carried at primarily their contractual amounts, including accrued interest, as specified in the respective agreements. The carrying amount of the Company’s repurchase agreements approximates fair value as the debt is short-term in nature.
	The Company pledges certain securities as collateral under repurchase agreements with financial institutions, the terms and conditions of which are negotiated on a transaction-by-transaction basis. The amounts available to be borrowed are dependent upon the fair value of the securities pledged as collateral, which fluctuates with changes in interest rates, type of security and liquidity conditions within the banking, mortgage finance and real estate industries. In response to declines in fair value of pledged securities, lenders may require the Company to post additional collateral or pay down borrowings to re-establish agreed upon collateral requirements, referred to as margin calls. As of December 31, 2013 and December 31, 2012, the Company met all margin call requirements.
	In instances where the Company acquires assets through repurchase agreements with the same counterparty from whom the assets were purchased, the Company evaluates such transactions in accordance with ASC 860-10. This standard requires the initial transfer of a financial asset and repurchase financing that are entered into contemporaneously with, or in contemplation of, one another to be considered linked unless all of the criteria found in ASC 860-10 are met at the inception of the transaction. If the transaction meets all of the conditions, the initial transfer shall be accounted for separately from the repurchase financing, and the Company will record the assets and the related financing on a gross basis on its balance sheet with the corresponding interest income and interest expense in the statements of operations. If the transaction is determined to be linked, the Company will record the initial transfer and repurchase financing on a net basis and record a forward commitment to purchase assets as a derivative instrument with changes in market value being recorded on the consolidated statement of operations. Such forward commitments are recorded at fair value with subsequent changes in fair value recognized in income. The Company refers to these transactions as Linked Transactions. When or if a transaction is no longer considered to be linked, the real estate security and related repurchase financing will be reported on a gross basis. The unlinking of a transaction causes a realized event in which the fair value of the real estate security as of the date of unlinking will become the cost basis of the real estate security. The difference between the fair value on the unlinking date and the existing cost basis of the security will be the realized gain or loss. Recognition of effective yield for such security will be calculated prospectively using the new cost basis.
Derivatives, Policy [Policy Text Block]	'
	Accounting for derivative financial instruments
	The Company may enter into derivative contracts, including interest rate swaps and interest rate caps, as a means of mitigating its interest rate risk. The Company uses interest rate derivative instruments to mitigate interest rate risk rather than to enhance returns. The Company accounts for derivative financial instruments in accordance with ASC 815-10, “Derivatives and Hedging.” ASC 815-10 requires an entity to recognize all derivatives as either assets or liabilities on the balance sheet and to measure those instruments at fair value. Additionally, the fair value adjustments 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 hedge for accounting purposes and, if so, the nature of the hedging activity. As of December 31, 2013 and December 31, 2012, the Company did not have any interest rate derivatives designated as hedges. All derivatives have been recorded at fair value in accordance with ASC 820-10, with corresponding changes in value recognized in the consolidated statement of operations. The Company records derivative asset and liability positions on a gross basis.
To Be Announced Securities [Policy Text Block]	'
	To-be-announced securities
	A to-be-announced security (“TBA”) is a futures contract for the purchase or sale of Agency RMBS at a predetermined price, face amount, issuer, coupon and stated maturity on an agreed-upon future date. The specific Agency RMBS delivered into or received from the contract upon the settlement date, published each month by the Securities Industry and Financial Markets Association, are not known at the time of the transaction. TBAs are exempt from ASC 815 and are accounted for under ASC 320 if there is no other way to purchase or sell that security, if delivery or receipt of that security and settlement will occur within the shortest period possible for that type of security and if it is probable at inception and throughout the term of the individual contract that physical delivery or receipt of the security will occur (referred to as the “regular-way” exception). Unrealized gains and losses associated with TBA contracts not subject to the regular-way exception or not designated as hedging instruments are recognized in the consolidated statement of operations in the line item “unrealized gain/(loss) on derivative and other instruments, net.”
Us Treasury Securities [Policy Text Block]	'
	Short positions in U.S. Treasury securities through reverse repurchase agreements
	The Company may sell short U.S. Treasury securities contracts to help mitigate the potential impact of changes in interest rates. The Company may borrow securities to cover short sales of U.S. Treasury securities under reverse repurchase agreements, which are accounted for as borrowing transactions, and the Company recognizes an obligation to return the borrowed securities at fair value on its consolidated balance sheet based on the value of the underlying borrowed securities as of the reporting date. The Company establishes haircuts to ensure the market value of the underlying assets remains sufficient to protect the Company in the event of default by the counterparty. Realized and unrealized gains and losses associated with purchases and short sales of U.S. Treasury securities are recognized in “net realized gain/(loss)”, and “unrealized gain/(loss) on derivative and other instruments, net”, respectively, on our consolidated statements of operations.
Manager Remuneration [Policy Text Block]	'
	Manager compensation
	The management agreement provides for payment to the Manager of a management fee. The management fee is accrued and expensed during the period for which it is calculated and earned. For a more detailed discussion on the fees payable under the management agreement, see Note 9.
Income Tax, Policy [Policy Text Block]	'
	Income taxes
	The Company conducts its operations to qualify and be taxed as a REIT. Accordingly, the Company will generally not be subject to federal or state corporate income tax to the extent that the Company makes qualifying distributions to its stockholders, and provided that it 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, it will be subject to U.S. federal, state and local income taxes and may be precluded from qualifying as a REIT for the four taxable years following the year in which the Company fails to qualify as a REIT.
	The dividends paid deduction of a REIT for qualifying dividends to its stockholders is computed using the Company’s taxable income as opposed to net income reported under GAAP in the financial statements. Taxable income, generally, will differ from net income reported on the financial statements because the determination of taxable income is based on tax provisions and not financial accounting principles.
	The Company has elected to treat certain entities including AG MIT II, LLC, AG MITT RMAT 2013, LLC, AG MITT RMAT 2013 II, LLC and AG MIT International LLC as taxable REIT subsidiaries (“TRSs”) and may elect to treat other subsidiaries as TRSs. In general, a TRS may hold assets and engage in activities that the Company cannot hold or engage in directly and generally may engage in any real estate or non-real estate-related business.
	While a domestic TRS will generate net income, a domestic TRS can declare dividends to the Company which will be included in the Company’s taxable income and necessitate a distribution to stockholders. Conversely, if the Company retains earnings at the domestic TRS level, no distribution is required and the Company can increase book equity of the consolidated entity. A domestic TRS is subject to U.S. federal, state and local corporate income taxes.
	AG MIT International LLC is domiciled in Anguilla and, accordingly, taxable income generated by this foreign TRS may not be subject to local income taxation, but generally will be included in the Company’s income on a current basis as Subpart F income, whether or not distributed.
	The Company’s financial results are generally not expected to reflect provisions for current or deferred income taxes, except for any activities conducted through one or more TRSs that are subject to corporate income taxation. The Company believes that it will operate in a manner that will allow it to qualify for taxation as a REIT. As a result of the Company’s expected REIT qualification, it does not generally expect to pay federal or state corporate income tax. Many of the REIT requirements, however, are highly technical and complex. If the Company were to fail to meet the REIT requirements, it would be subject to federal income taxes and applicable state and local taxes. During the year ended December 31, 2013, the Company recognized income tax expense of $3.0 million related to the income and sale of investments held within AG MITT RMAT 2013, LLC and AG MITT RMAT 2013 II, LLC. The Company did not record an income tax provision or expense as of December 31, 2012.
	As a REIT, if the Company fails to distribute in any calendar year 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.
	The Company evaluates uncertain income tax positions, if any, in accordance with ASC Topic 740, “Income Taxes”. The Company classifies interest and penalties, if any, related to unrecognized tax benefits as a component of provision for income taxes. See Note 9 for further details.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Stock-based compensation
	The Company applies the provisions of ASC 718, “Compensation—Stock Compensation” with regard to its equity incentive plans. ASC 718 covers a wide range of share-based compensation arrangements including stock options, restricted stock plans, performance-based awards, stock appreciation rights and employee stock purchase plans. ASC 718 requires that compensation cost relating to stock-based payment transactions be recognized in financial statements. The cost is measured based on the fair value of the equity or liability instruments issued.
	Compensation cost related to restricted common shares issued to the Company’s directors is measured at its estimated fair value at the grant date, and is amortized and expensed over the vesting period on a straight-line basis. Compensation cost related to restricted common shares issued to the Manager is initially measured at estimated fair value at the grant date, and is remeasured on subsequent dates to the extent the awards are unvested. The Company has elected to use the straight-line method to amortize compensation expense for the restricted common shares granted to the Manager.
New Accounting Pronouncements, Policy [Policy Text Block]	'
	Recent accounting pronouncements
	In December 2011, the FASB issued Accounting Standards Updated 2011-11, “Disclosures about Offsetting Assets and Liabilities” (ASU 2011-11). ASU 2011-11 amends Topic 210 to require additional disclosure information about offsetting and related arrangements. Entities will be required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. This scope would include derivatives, sale and repurchase agreements and reverse sale and repurchase agreements. The objective of this disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of US GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards (IFRS). The guidance is effective for periods beginning on or after January 1, 2013, and interim periods within those annual periods. This disclosure was adopted and the adoption of this update did not have a material effect on the Company’s consolidated financial statements.
	In January 2013, the FASB issued ASU 2013-01, “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities” (ASU 2013-1). ASU 2013-1 addresses implementation issues about ASU 2011-11 and applies to derivatives accounted for in accordance with ASC 815-10, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with ASC 210-20 “Balance Sheet – Offsetting” or ASC 815 or subject to an enforceable master netting arrangement or similar agreement. The guidance was effective January 1, 2013 and was applied retrospectively. As a result, the guidance does not have a material effect on the Company's financial statements.
	In July 2013, the FASB issued ASU 2013-11, “Income Taxes” (“ASU 2013-11”). ASU 2013-11 states an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. For example, an entity should not evaluate whether the deferred tax asset expires before the statute of limitations on the tax position or whether the deferred tax asset may be used prior to the unrecognized tax benefit being settled. As a result, the guidance does not have a material effect on the Company's financial statements.
