ELLINGTON RESIDENTIAL MORTGAGE REIT
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2016March 31, 2017
(UNAUDITED)
1. Organization and Investment Objective
Ellington Residential Mortgage REIT, or "EARN," was formed as a Maryland real estate investment trust, or "REIT," on August 2, 2012, and commenced operations on September 25, 2012. EARN conducts its business through its wholly owned subsidiaries, EARN OP GP LLC, or the "General Partner," and Ellington Residential Mortgage LP, or the "Operating Partnership," which were formed as a Delaware limited liability company and a Delaware limited partnership, respectively, on July 31, 2012 and commenced operations on September 25, 2012. The Operating Partnership conducts its business of acquiring, investing in, and managing residential mortgage-relatedmortgage- and real estate-related assets through its wholly owned subsidiaries. EARN, the General Partner, the Operating Partnership, and their consolidated subsidiaries are hereafter defined as the "Company."
Ellington Residential Mortgage Management LLC, or the "Manager," serves as the Manager of the Company pursuant to the terms of the Fourth Amended and Restated Management Agreement, (theor the "Management Agreement").Agreement." The Manager is an affiliate of Ellington Management Group, L.L.C., or "EMG," an investment management firm that is an SEC-registered investment adviser with a 21-year22-year history of investing in a broad spectrum of mortgage-backed securities and related derivatives, with an emphasis on the residential mortgage-backed securities, or "RMBS," market. In accordance with the terms of the Management Agreement and the Services Agreement (as described in Note 9), the Manager is responsible for administering the Company's business activities and day-to-day operations, and performs certain services, subject to oversight by the Board of Trustees. See Note 9 for further information on the Management Agreement.
The Company acquires and manages RMBS, for which the principal and interest payments are guaranteed by a U.S. government agency or a U.S. government-sponsored entity, or "Agency RMBS," and RMBS that do not carry such guarantees, or "non-Agency RMBS," such as RMBS backed by prime jumbo, Alternative A-paper, manufactured housing, and subprime residential mortgage loans. Agency RMBS include both Agency pools and Agency collateralized mortgage obligations, or "CMOs," and non-Agency RMBS primarily consist of non-Agency CMOs, both investment grade and non-investment grade. The Company may also acquire and manage mortgage servicing rights, residential mortgage loans, and other mortgage- and real estate-related assets. The Company may also invest in other instruments including, but not limited to, forward-settling To-Be-Announced Agency pass-through certificates, or "TBAs," interest rate swaps and swaptions, U.S. Treasury securities, Eurodollar and U.S. Treasury futures, other financial derivatives, and cash equivalents. The Company's targeted investments may range from unrated first loss securities to AAA senior securities.
The Company has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, or "the Code," and intends to conduct its operations to be qualified and taxed as a REIT. As a REIT, the Company is required to distribute annually at least 90% of its taxable income. As long as the Company continues to qualify as a REIT, it will not be subject to U.S. federal corporate taxes on its taxable income to the extent that it distributes all of its annual taxable income to its shareholders. It is the intention of the Company to distribute at least 100% of its taxable income, after application of available tax attributes, within the time limits prescribed by the Code, which may extend into the subsequent taxable year.
2. Significant Accounting Policies
(A) Basis of Presentation: The Company's unaudited interim consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America, or "U.S. GAAP." Entities in which the Company has a controlling financial interest, through ownership of the majority of the entities' voting equity interests, or through other contractual rights that give the Company control, are consolidated by the Company. All inter-company balances and transactions have been eliminated. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and those differences could be material. In management's opinion, all material adjustments considered necessary for a fair presentationstatement of the Company's interim consolidated financial statements have been included and are only of a normal recurring nature. Interim results are not necessarily indicative of the results that may be expected for the entire fiscal year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2015.2016.
(B) Valuation: The Company applies ASC 820-10, Fair Value Measurement and Disclosures ("("ASC 820-10"), to its holdings of financial instruments. ASC 820-10 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation


measurements. The valuation hierarchy is based upon the observability of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:
Level 1—inputs to the valuation methodology are observable and reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Currently, the types of financial instruments the Company generally includes in this category are exchange-traded derivatives;
Level 2—inputs to the valuation methodology other than quoted prices included in Level 1 are observable for the asset or liability, either directly or indirectly. Currently, the types of financial instruments that the Company generally includes in this category are Agency RMBS, non-Agency RMBS determined to have sufficiently observable market data, U.S. Treasury securities, actively traded derivatives such as TBAs, interest rate swaps, and swaptions; and
Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement. Currently, this category includes RMBS where there is less price transparency.
For certain financial instruments, the various inputs that management uses to measure fair value for such financial instrument may fall into different levels of the fair value hierarchy. In such cases, the determination of which category within the fair value hierarchy is appropriate for such financial instrument is based on the lowest level of input that is significant to the fair value measurement. ASC 820 prioritizes the various inputs that management uses to measure fair value with the highest priority to inputs that are observable and reflect quoted prices (unadjusted) for identical assets or liabilities in active markets (Level 1) and the lowest priority to inputs that are unobservable and significant to the fair value measurement (Level 3). The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. The Company may use valuation techniques consistent with the market and income approaches to measure the fair value of its assets and liabilities. The market approach uses third-party valuations and information obtained from market transactions involving identical or similar assets or liabilities. The income approach uses projections of the future economic benefits of an instrument to determine its fair value, such as in the discounted cash flow methodology. The inputs or methodology used for valuing financial instruments are not necessarily an indication of the risk associated with investing in these financial instruments. Transfers between levels of the fair value hierarchy are assumed to occur at the end of the reporting period.
Summary Valuation Techniques
For financial instruments that are traded in an "active market," the best measure of fair value is the quoted market price. However, many of the Company's financial instruments are not traded in an active market. Therefore, management generally uses third-party valuations when available. If third-party valuations are not available, management uses other valuation techniques, such as the discounted cash flow methodology. The following are summary descriptions, for the various categories of financial instruments, of the valuation methodologies management uses in determining fair value of the Company's financial instruments in such categories. Management utilizes such methodologies to assign a good faith fair value (the estimated price that, in an orderly transaction at the valuation date, would be received to sell an asset, or paid to transfer a liability, as the case may be) to each such financial instrument.
Valuations for fixed rate RMBS pass-throughs issued by a U.S government agency or government-sponsored enterprise, or "GSE," are typically based on observable pay-up data (pay-ups are price premiums for specified categories of fixed rate pools relative to their TBA counterparts) or models that use observable market data, such as interest rates and historical prepayment speeds, and are validated against third-party valuations. With respect to the Company's other RMBS investments and TBAs, management seeks to obtain at least one third-party valuation, and often obtains multiple valuations when available. Management has been able to obtain third-party valuations on the vast majority of these instruments and expects to continue to solicit third-party valuations in the future. Management generally values each financial instrument at the average of third-party valuations received and not rejected as described below. Third-party valuations are not binding, and while management generally does not adjust the valuations it receives, management may challenge or reject a valuation when, based on its validation criteria, management determines that such valuation is unreasonable or erroneous. Furthermore, based on its validation criteria, management may determine that the average of the third-party valuations received for a given instrument does not result in what management believes to be the fair value of such instrument, and in such circumstances management may override this average with its own good faith valuation. The validation criteria may take into account output from management's own models, recent trading activity in the same or similar instruments, and valuations received from third parties. The use of proprietary models requires the use of a significant amount of judgment and the application of various assumptions including, but not limited to, assumptions concerning future prepayment rates and default rates.
Given their relatively high level of price transparency, Agency RMBS pass-throughs and TBAs are typically designated as Level 2 assets, although Agency interest only and inverse interest only RMBS are currently designated as Level 3 assets since they generally have less price transparency. Non-Agency RMBS are generally classified as either Level 2 or Level 3 based on


analysis of available market data such as recent trades and executable bids. Furthermore, the methodology used by the third-party valuation providers is reviewed at least annually by management, so as to ascertain whether such providers are utilizing observable market data to determine the valuations that they provide.
Interest rate swaps and swaptions are typically valued based on internal models that use observable market data, including applicable interest rates in effect as of the measurement date; the model-generated valuations are then typically compared to counterparty valuations for reasonableness. These financial derivatives are generally designated as Level 2 instruments.
In valuing its derivatives, the Company also considers the creditworthiness of both the Company and its counterparties, along with collateral provisions contained in each derivative agreement.
The Company's repurchase and reverse repurchase agreements are carried at cost, which approximates fair value. Repurchase agreements and reverse repurchase agreements are classified as Level 2 assets and liabilities based on the adequacy of the collateral and their short term nature.
The Company's valuation process, including the application of validation criteria, is overseen by the Manager's Valuation Committee.Committee ("Valuation Committee"). The Valuation Committee includes senior level executives from various departments within the Manager, and each quarter the Valuation Committee reviews and approves the valuations of the Company's investments. The valuation process also includes a monthly review by the Company's third party administrator. The goal of this review is to replicate various aspects of the Company's valuation process based on the Company's documented procedures.
Because of the inherent uncertainty of valuation, the estimated fair value of the Company's financial instruments may differ significantly from the values that would have been used had a ready market for the financial instruments existed, and the differences could be material to the consolidated financial statements.
(C) Accounting for Securities: Purchases and sales of investments are recorded on trade date and realized and unrealized gains and losses are calculated based on identified cost.
The Company has chosen to make a fair value election pursuant to ASC 825-10, Financial Instruments, for its securities portfolio. Electing the fair value option allows the Company to record changes in fair value in the Consolidated Statement of Operations, which, in management's view, more appropriately reflects the results of operations for a particular reporting period as all securities activities will be recorded in a similar manner. As such, securities are recorded at fair value on the Consolidated Balance Sheet and the period change in fair value is recorded in current period earnings on the Consolidated Statement of Operations as a component of Change in net unrealized gains (losses) on securities.
(D) Interest Income: Coupon interest income on investment securities is accrued based on the outstanding principal balance or notional amount and the current coupon rate on each security. The Company amortizes purchase premiums and accretes purchase discounts on its fixed income securities. For RMBS that are deemed to be of high credit quality at the time of purchase, premiums and discounts are generally amortized/accreted into interest income over the life of such securities using the effective interest method. For securities whose cash flows vary depending on prepayments, anAn effective yield retroactive to the time of purchase is periodically recomputed based on actual prepayments and changes in projected prepayment activity, and a catch-up adjustment, or "Catch-up Premium Amortization Adjustment," is made to amortization to reflect the cumulative impact of the change in effective yield. For RMBS that are deemed not to be of high credit quality at the time of purchase, interest income is recognized based on the effective interest method. For purposes of determining the effective interest rate, management estimates the future expected cash flows of its investment holdings based on assumptions including, but not limited to, assumptions for future prepayment rates, default rates, and loss severities (each of which may in turn incorporate various macro-economic assumptions, such as future housing prices). These assumptions are re-evaluated not less than quarterly. Principal write-offs are generally treated as realized losses. Changes in projected cash flows, as applied to the current amortized cost of the security, may result in a prospective change in the yield/interest income recognized on such securities.
The Company's accretion of discounts and amortization of premiums on securities for U.S. federal and other tax purposes is likely to differ from the accounting treatment under U.S. GAAP of these items as described above.
(E) Cash and Cash Equivalents: Cash and cash equivalents include cash and short term investments with original maturities of three months or less at the date of acquisition. Cash and cash equivalents typically include amounts held in an interest bearing overnight account and amounts held in money market funds, and these balances generally exceed insured limits. The Company holds its cash at institutions that it believes to be highly creditworthy.
(F) Due from brokers/Due to brokers: Due from brokers and Due to brokers accounts on the Consolidated Balance Sheet include collateral transferred to or received from counterparties, including clearinghouses, along with receivables and payables for open and/or closed derivative positions.


(G) Financial Derivatives: The Company enters into various types of financial derivatives subject to its investment guidelines, which include restrictions associated with maintaining its qualification as a REIT. The Company's financial derivatives are predominantly subject to bilateral collateral arrangements or clearing in accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. The Company may be required to deliver or may receive cash or securities as collateral upon entering into derivative transactions. In addition, changes in the relative value of financial derivative transactions may require the Company or the counterparty to post or receive additional collateral. In the case of cleared financial derivatives, the clearinghouse becomes the Company's counterparty and a futures commission merchant acts as intermediary between the Company and the clearinghouse with respect to all facets of the related transaction, including the posting and receipt of required collateral. Collateral received by the Company is reflected on the Consolidated Balance Sheet as "Due to Brokers." Conversely, collateral posted by the Company is reflected as "Due from Brokers" on the Consolidated Balance Sheet. The types of financial derivatives that have been utilized by the Company to date are interest rate swaps, TBAs, swaptions, and futures.
Swaps: The Company enters into interest rate swaps. Interest rate swaps are contractual agreements whereby one party pays a floating interest rate on a notional principal amount and receives a fixed rate payment on the same notional principal, or vice versa, for a fixed period of time. The Company enters into interest rate swap contracts primarily to mitigate interest rate risk. The Company is subject to interest rate risk exposure in the normal course of pursuing its investment objectives.
Swaps change in value with movements in interest rates or total return of the reference securities. During the term of swap contracts, changes in value are recognized as unrealized gains or losses on the Consolidated Statement of Operations. When a contract is terminated, the Company realizes a gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Company's basis in the contract, if any. Periodic payments or receipts required by swap agreements are recorded as unrealized gains or losses when accrued and realized gains or losses when received or paid. Upfront payments paid and/or received by the Company to open swap contracts are recorded as an asset and/or liability on the Consolidated Balance Sheet and are recorded as a realized gain or loss on the termination date.
TBA Securities: The Company transacts in the forward settling TBA market. A TBA position is a forward contract for the purchase ("long position") or sale ("short position") of Agency RMBS at a predetermined price, face amount, issuer, coupon, and maturity on an agreed-upon future delivery date. For each TBA contract and delivery month, a uniform settlement date for all market participants is determined by the Securities Industry and Financial Markets Association. The specific Agency RMBS to be delivered into the contract at the settlement date are not known at the time of the transaction. The Company typically does not take delivery of TBAs, but rather enters into offsetting transactions and settles the associated receivable and payable balances with its counterparties. The Company primarily uses TBAs to mitigate interest rate risk, but from time to time it also holds net long positions in certain TBA securities as a means of acquiring exposure to Agency RMBS.
TBAs are accounted for by the Company as financial derivatives. The difference between the contract price and the fair value of the TBA position as of the reporting date is included in Change in net unrealized gains (losses) on financial derivatives in the Consolidated Statement of Operations. Upon settlement of the TBA contract, the realized gain (loss) on the TBA contract is equal to the net cash amount received (paid).
Options: The Company enters into swaption contracts. It may purchase or write put, call, straddle, or other similar options contracts. The Company enters into options contracts primarily to help mitigate interest rate risk. When the Company purchases an options contract, the option asset is initially recorded at an amount equal to the premium paid, if any, and is subsequently marked-to-market. Premiums paid for purchasing options contracts that expire unexercised are recognized on the expiration date as realized losses. If an options contract is exercised, the premium paid is subtracted from the proceeds of the sale or added to the cost of the purchase to determine whether the Company has realized a gain or loss on the related investment transaction. When the Company writes an options contract, the option liability is initially recorded at an amount equal to the premium received, if any, and is subsequently marked-to-market. Premiums received for writing options contracts that expire unexercised are recognized on the expiration date as realized gains. If an options contract is exercised, the premium received is subtracted from the cost of the purchase or added to the proceeds of the sale to determine whether the Company has realized a gain or loss on the related investment transaction. When the Company enters into a closing transaction, the Company will realize a gain or loss depending upon whether the amount from the closing transaction is greater or less than the premiums paid or received. In general, the Company's options contracts contain forward-settling premiums. In this case, no money is exchanged upfront; instead, the agreed-upon premium is paid by the buyer upon expiration of the options contract, regardless of whether or not the options contract is exercised. Unrealized gains or (losses) resulting from the options contract being marked-to-market are included in Change in net unrealized gains (losses) on financial derivatives in the Consolidated Statement of Operations. Realized gains or (losses) are included in Realized gains (losses) on financial derivatives in the Consolidated Statement of Operations.


Futures Contracts: The Company enters into Eurodollar futures contracts and U.S. Treasury futures contracts. A futures contract is an exchange-traded agreement to buy or sell an asset for a set price on a future date. Initial margin deposits are made upon entering into futures contracts and can be either in the form of cash or securities. During the period the futures contract is open, changes in the value of the contract are recognized as unrealized gains or losses by marking-to-market to reflect the current market value of the


contract. Unrealized gains or (losses) are included in Change in net unrealized gains (losses) on financial derivatives in the Consolidated Statement of Operations. Variation margin payments are made or received periodically, depending upon whether unrealized losses or gains are incurred. When the contract is closed, the Company records a realized gain or loss equal to the difference between the proceeds of the closing transaction and the Company's basis in the contract. Realized gains or (losses) are included in Realized gains (losses) on financial derivatives in the Consolidated Statement of Operations.
Financial derivative assets are included in Financial derivatives–assets, at fair value on the Consolidated Balance Sheet while financial derivative liabilities are included in Financial derivatives–liabilities, at fair value on the Consolidated Balance Sheet.
(H) Repurchase Agreements: The Company enters into repurchase agreements with third-party broker-dealers, whereby it sells securities under agreements to repurchase at an agreed upon price and date. The Company accounts for repurchase agreements as collateralized borrowings, with the initial sale price representing the amount borrowed, and with the future repurchase price consisting of the amount borrowed plus interest, at the implied interest rate of the repurchase agreement, on the amount borrowed over the term of the repurchase agreement. The interest rate on a repurchase agreement is based on competitive market rates (or competitive market spreads, in the case of agreements with floating interest rates) at the time such agreement is entered into. When the Company enters into a repurchase agreement, the lender establishes and maintains an account containing cash and/or securities having a value not less than the repurchase price, including accrued interest, of the repurchase agreement. Repurchase agreements are carried at their contractual amounts, which approximate fair value due to their short-term nature.
(I) Reverse Repurchase Agreements: The Company enters into reverse repurchase agreement transactions with third-party broker-dealers, whereby it purchases securities under agreements to resell at an agreed upon price and date. The interest rate on a reverse repurchase agreement is based on competitive market rates (or competitive market spreads, in the case of agreements with floating interest rates) at the time such agreement is entered into. Reverse repurchase agreements are carried at their contractual amounts, which approximate fair value due to their short-term nature.
Repurchase and reverse repurchase agreements that are conducted with the same counterparty can be reported on a net basis if they meet the requirements of ASC 210-20, Balance Sheet Offsetting.
There are currently no repurchase and reverse repurchase agreements reported on a net basis in the Company's consolidated financial statements.
(J) Securities Sold Short: The Company may purchase or engage in short sales of U.S. Treasury securities to mitigate the potential impact of changes in interest rates on the performance of its portfolio. When the Company sells securities short, it typically satisfies its security delivery settlement obligation by obtaining the security sold short from the same or a different counterparty. The Company generally is required to deliver cash or securities as collateral to the counterparty for the Company's obligation to return the borrowed security.
The Company has chosen to make a fair value election pursuant to ASC 825-10, Financial Instruments, for its securities sold short. Electing the fair value option allows the Company to record changes in fair value in the Consolidated Statement of Operations, which, in management's view, more appropriately reflects the results of operations for a particular reporting period as all securities activities will be recorded in a similar manner. As such, securities sold short are recorded at fair value on the Consolidated Balance Sheet and the period change in fair value is recorded in current period earnings on the Consolidated Statement of Operations as a component of Change in net unrealized gains (losses) on securities. A realized gain or loss will be recognized upon the termination of a short sale if the market price is less or greater than the proceeds originally received. Such realized gain or loss is recorded on the Company's Consolidated Statement of Operations in Net realized gains (losses) on securities.
(K) Offering Costs/Deferred Offering Costs: Offering costs are charged against shareholders' equity within Additional paid-in-capital, and typically include legal, accounting, printing, and other fees associated with the cost of raising equity capital.
(L) Share Based Compensation: The Company applies the provisions of ASC 718, Compensation—Stock Compensation ("ASC 718"), with regard to its equity incentive plans. ASC 718 covers a wide range of share-based compensation arrangements including share options, restricted share plans, performance-based awards, share appreciation rights, and employee share purchase plans. ASC 718 requires that compensation cost relating to share-based payment transactions be recognized in financial statements. The cost is measured based on the fair value, at the grant date, of the equity or liability


instruments issued and is amortized over the vesting period. Restricted shares issued to the Company's independent directors and partially dedicated personnel are participating securities and receive dividends prior to vesting. Fair value for such awards is based on the closing stock price on the New York Stock Exchange at the grant date. The vesting period for restricted share awards is typically one to two years.
(M) Dividends: Dividends payable are recorded on the declaration date.


(N) Expenses: Expenses are recognized as incurred on the Consolidated Statement of Operations.
(O) Earnings Per Share: In accordance with the provisions of ASC 260, Earnings per Share, the Company calculates basic income (loss) per share by dividing net income (loss) for the period by the weighted average of the Company's common shares outstanding for that period. Diluted income (loss) per share takes into account the effect of dilutive instruments, such as share options and warrants, and 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.
(P) Share Repurchases: Common shares that are repurchased by the Company subsequent to issuance decrease the total number of shares issued and outstanding and are immediately retired upon settlement. The cost of such share repurchases is charged against Additional paid-in-capital on the Company's Consolidated Balance Sheet.
(Q) Income Taxes: The Company has elected to be taxed as a REIT under Sections 856 to 860 of the Code. As a REIT, the Company is generally not subject to corporate-level federal and state income tax on net income it distributes to its shareholders. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including the distribution of at least 90% of its annual taxable income to shareholders. Even if the Company qualifies as a REIT, it may be subject to certain federal, state, local and foreign taxes on its income and property and to federal income and excise taxes on its undistributed taxable income. 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 Company follows the authoritative guidance on accounting for and disclosure of uncertainty on tax positions, which requires management to determine whether a tax position of the Company is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals or litigation processes, based on the technical merits of the position. For uncertain tax positions, the tax benefit to be recognized is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. The Company did not have any unrecognized tax benefits resulting from tax positions related to the current period or to 2016, 2015, 2014, or 2013 (its open tax years). In the normal course of business, the Company may be subject to examination by federal, state, local, and foreign jurisdictions, where applicable, for the current period, 2016, 2015, 2014, and 2013 (its open tax years). The Company may take positions with respect to certain tax issues which depend on legal interpretation of facts or applicable tax regulations. Should the relevant tax regulators successfully challenge any of such positions, the Company might be found to have a tax liability that has not been recorded in the accompanying consolidated financial statements. Also, management's conclusions regarding the authoritative guidance may be subject to review and adjustment at a later date based on changing tax laws, regulations, and interpretations thereof. There were no amounts accrued for penalties or interest as of or during the periods presented in these consolidated financial statements.
(R) Recent Accounting Pronouncements: Under the Jumpstart Our Business Startups Act, or the "JOBS Act," the Company meets the definition of an "emerging growth company." The Company has elected to follow the extended transition period for complying with new or revised U.S. accounting standards pursuant to Section 107(b) of the JOBS Act. As a result, the Company will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-public entities.
In June 2014, the FASB issued ASU No. 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures ("ASU 2014-11"). This amends ASC 860, Transfers and Servicing ("ASC 860"), to require disclosure of repurchase-to-maturity transactions to be accounted for as secured borrowings rather than sales of an asset, and transfers of financial assets with a contemporaneous repurchase agreement will no longer be evaluated to determine whether they should be accounted for on a combined basis as forward contracts. The new guidance also prescribes additional disclosures particularly on the nature of collateral pledged under repurchase agreements accounted for as secured borrowings. ASU 2014-11 is effective for annual periods beginning after December 15, 2014 and interim periods beginning after December 31, 2015. The adoption of ASC 860, as amended by ASU 2014-11 did not have a material impact on the Company's consolidated financial statements.
In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern ("ASU 2014-15"). ASU 2014-15 requires management to perform interim and annual assessments of an entity's ability to continue as a going concern and to provide disclosure if events or conditions arise that would place substantial doubt on the entity's ability to continue as a going concern. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and subsequent interim and annual periods with early adoption permitted. The adoption of ASU 2014-15 is not expected to have a material impact on the Company's consolidated financial statements.
In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis ("ASU 2015-02"). This amends ASC 810, Consolidation (ASC "810"), to improve targeted areas of consolidation guidance by simplifying the


requirements of consolidation and placing more emphasis on risk of loss when determining a controlling financial interest. ASU 2015-02 is effective for annual periods beginning after December 15, 2016 and interim periods beginning after December 15, 2017 with early adoption permitted. The adoption of ASU 2015-02 is not expected to have a material impact on the Company's consolidated financial statements.
3. Mortgage-Backed Securities
The following tables present details of the Company's mortgage-backed securities portfolio at September 30, 2016March 31, 2017 and December 31, 2015,2016, respectively. The Company's Agency RMBS include mortgage pass-through certificates and CMOs representing interests in or obligations backed by pools of residential mortgage loans issued or guaranteed by a U.S. government agency or GSE. The non-Agency RMBS portfolio is not issued or guaranteed by the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation, or any agency of the U.S. Government and is therefore subject to greater credit risk.

DuringThere were no transfers of financial instruments between Levels 1 and 2 of the ninefair value hierarchy during the three month periodperiods ended September 30, 2015, the Company transferred $4.0 million of non-Agency RMBS from Level 2 to Level 3. Following DecemberMarch 31, 2014, these securities exhibited indications of a reduced level of price transparency. Examples of such indications include wider spreads and/2017 or higher delinquencies relative to similar securities and a reduction in observable transactions or executable quotes involving these and similar securities. Changes in these indications could impact price transparency, and thereby cause a change in the level designation in future periods.2016.

Third-party non-binding valuations are validated by comparing such valuations to internally generated prices based on the Company's models and to recent trading activity in the same or similar instruments. For those instruments valued using discounted cash flows, collateral prepayments, losses, recoveries, and scheduled amortization are projected over the remaining life of the collateral and expressed as a percentage of the collateral's current principal balance. For those assets valued using the LIBOR Option Adjusted Spread, or "OAS," valuation methodology, cash flows are projected using the Company's models over multiple interest rate scenarios, and these projected cash flows are then discounted using the LIBOR rates implied by each interest rate scenario. The LIBOR OAS of an asset is then computed as the unique constant yield spread that, when added to all LIBOR rates in each interest rate scenario generated by the model, will equate (a) the expected present value of the projected asset cash flows over all model scenarios to (b) the actual current market price of the asset. LIBOR OAS is therefore model-dependent. Generally speaking, LIBOR OAS measures the additional yield spread over LIBOR that an asset provides at its current market price after taking into account any interest rate options embedded in the asset.
Material changes in any of the inputs above in isolation could result in a significant change to reported fair value measurements. Fair value measurements are impacted by the interrelationships of these inputs. For example, a higher expectation of collateral prepayments will generally result in a lower expectation of collateral losses. Conversely, higher losses will generally result in lower prepayments.

Cash and cash equivalents includes cash held in an interest bearing overnight account for which fair value equals the carrying value and cash held in money market accounts which are liquid in nature and for which fair value equals the carrying value; such assets are considered Level 1 assets. Due from brokers and Due to brokers include collateral transferred to or received from counterparties, along with receivables and payables for open and/or closed derivative positions. These receivables and payables are short term in nature and any collateral transferred consists primarily of cash; fair value of these items approximates carrying value and such items are considered Level 1 assets and liabilities. The Company's repurchase and reverse repurchase agreements are carried at cost, which approximates fair value due to their short term nature. Repurchase agreements and reverse repurchase agreements are classified as Level 2 assets and liabilities based on the adequacy of the collateral and their short term nature.
5. Financial Derivatives
The Company is exposed to certain risks arising from both its business operations and economic conditions. Specifically, the Company's primary source of financing is repurchase agreements and the Company enters into financial derivative and other instruments to manage exposure to variable cash flows on portions of its borrowings under those repurchase agreements. Since the interest rates on repurchase agreements typically change with market interest rates such as LIBOR, the Company is exposed to constantly changing interest rates, which accordingly affects cash flows associated with the Company's borrowings. To mitigate the effect of changes in these interest rates and their related cash flows, the Company may enter into a variety of derivative contracts, including interest rate swaps, swaptions, and TBAs. Additionally, from time to time, the Company may use short positions in U.S. Treasury securities to mitigate its interest rate risk.

TBAs
The Company transacts in the forward settling TBA market. Pursuant to these TBA transactions, the Company agrees to purchase or sell, for future delivery, Agency RMBS with certain principal and interest terms and certain types of underlying collateral, but the particular Agency RMBS to be delivered is not identified until shortly before the TBA settlement date. TBAs are liquid and have quoted market prices and represent the most actively traded class of MBS. The Company primarily uses TBAs to mitigate interest rate risk, typically in the form of short positions. However, from time to time the Company also invests in TBAs as a means of acquiring additional exposure to Agency RMBS, or for speculative purposes, including holding long positions. Overall, the Company typically holds a net short position.
The Company does not generally take delivery of TBAs; rather, it settles the associated receivable and payable with its trading counterparties on a net basis. Transactions with the same counterparty for the same TBA that result in a reduction of the position are treated as extinguished.
As of September 30, 2016March 31, 2017 and December 31, 2015,2016, the Company had outstanding contracts to purchase ("long positions") and sell ("short positions") TBA securities as follows:

6. Borrowings under Repurchase Agreements
The Company enters into repurchase agreements. A repurchase agreement involves the sale of an asset to a counterparty together with a simultaneous agreement to repurchase the transferred asset or similar asset from such counterparty at a future date. The Company accounts for its repurchase agreements as collateralized borrowings, with the transferred assets effectively serving as collateral for the related borrowing. The Company's repurchase agreements typically range in term from 30 to 180 days. The principal economic terms of each repurchase agreement—such as loan amount, interest rate, and maturity date—are typically negotiated on a transaction-by-transaction basis. Other terms and conditions, such as relating to events of default, are typically governed under the Company's master repurchase agreements. Absent an event of default, the Company maintains beneficial ownership of the transferred securities during the term of the repurchase agreement and receives the related principal and interest payments. Interest rates on these borrowings are generally 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, repay that counterparty and possibly negotiate financing terms with a different counterparty, or choose to no longer finance the related asset. In response to a decline in the fair value of the transferred securities, whether as a result of changes in market conditions, security paydowns, or other factors, repurchase agreement counterparties will typically make a margin call, whereby the Company will be required to post additional securities and/or cash as collateral with the counterparty in order to re-establish the agreed-upon collateralization requirements. In the event of increases in fair value of the transferred securities, the Company generally can require the counterparty to post collateral with it in the form of cash or securities. The Company is generally permitted to sell or re-pledge any securities posted by the counterparty as collateral; however, upon termination of the repurchase agreement, or other circumstance in which the counterparty is no longer required to post such margin, the Company must return to the counterparty the same security that had been posted. The contractual amount (loan amount) of the Company's repurchase agreements approximates fair value, based on the short-term nature of the debt and the adequacy of the collateral.


At any given time, the Company seeks to have its outstanding borrowings under repurchase agreements with several different counterparties in order to reduce the exposure to any single counterparty. As of each of September 30, 2016March 31, 2017 and December 31, 2015,2016, the Company had outstanding borrowings under repurchase agreements with thirteen counterparties.
The following table details the Company's outstanding borrowings under repurchase agreements as of September 30, 2016March 31, 2017 and December 31, 2015:2016:

8. Earnings Per Share
Basic earnings per share, or "EPS," is calculated by dividing net income (loss) for the period by the weighted average of the Company's common shares outstanding for the period. Diluted EPS takes into account the effect of outstanding dilutive instruments, such as share options and warrants, if any, and 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 September 30,March 31, 2017 and 2016, and 2015, the Company did not have any dilutive instruments outstanding.
The following table presents a reconciliation of the earnings/(losses) and shares used in calculating basic EPS for the three and nine month periods ended September 30, 2016March 31, 2017 and 2015:2016:

Executive Summary
We are a Maryland real estate investment trust, or "REIT," formed in August 2012 that specializes in acquiring, investing in, and managing residential mortgage- and real estate-related assets. Our primary objective is to generate attractive current yields and risk-adjusted total returns for our shareholders by making investments that we believe compensate us appropriately for the risks associated with them. We seek to attain this objective by constructing and actively managing a portfolio comprised primarily of residential mortgage-backed securities, or "RMBS," for which the principal and interest payments are guaranteed by a U.S. government agency or a U.S. government-sponsored entity, or "Agency RMBS," and, to a lesser extent, RMBS that do not carry such guarantees, or "non-Agency RMBS," such as RMBS backed by prime jumbo, Alternative A-paper, manufactured housing, and subprime residential mortgage loans. We also may opportunistically acquire and manage other types of residential mortgage-related and real estate-related asset classes, such as residential mortgage loans, and mortgage servicing rights, or "MSRs." We believe that being able to combine Agency RMBS with non-Agency RMBS and other residential mortgage- and real estate-related asset classes enables us to balance a range of mortgage-related risks.
We were formed through an initial strategic venture among affiliates of Ellington, an investment management firm and registered investment adviser with a 21-year22-year history of investing in a broad spectrum of mortgage-backed securitiesMBS and related derivatives, with an emphasis on the RMBS market, and the Blackstone Tactical Opportunity Funds, or the "Blackstone Funds." As of September 30, 2016,March 31, 2017, the Blackstone Funds owned approximately 29% of our outstanding common shares.
We are externally managed and advised by our Manager, an affiliate of Ellington.
We use leverage in our Agency RMBS strategy and, while we have not done so meaningfully to date, we may use leverage in our non-Agency RMBS strategy as well, although we expect such leverage to be lower. We have financed our purchases of Agency RMBS exclusively through repurchase agreements, which we account for as collateralized borrowings. As

of September 30, 2016,March 31, 2017, we had outstanding borrowings under repurchase agreements in the amount of $1.2 billion with thirteen counterparties.
We have elected to be taxed as a REIT for U.S. federal income tax purposes. Accordingly, we generally will not be subject to U.S. federal income taxes on our taxable income that we distribute currently to our shareholders as long as we maintain our qualification as a REIT. We intend to conduct our operations so that neither we nor any of our subsidiaries is required to register as an investment company under the Investment Company Act of 1940, as amended, or "Investment Company Act."
As of September 30, 2016,March 31, 2017, our book value per share was $15.70$15.35 as compared to $15.38 as of June 30, 2016 and $15.86$15.52 as of December 31, 2015.2016.
Trends and Recent Market Developments
Key trends and recent market developments for the mortgage-backed security, or "MBS,"MBS market include the following:
U.S. Federal Reserve and U.S. Monetary Policy—In September 2016,March 2017, the U.S. Federal Reserve, or "Federal Reserve," maintainedraised its target range for the federal funds rate andby 0.25%, but maintained its existing policy of reinvesting principal payments from its U.S. Treasury security and Agency RMBS holdings;holdings. However, minutes from the March Federal Open Market Committee, or "FOMC," meeting indicated that it may change its reinvestment policy later this year;
Housing and Mortgage Market Statistics—Data released by S&P Dow Jones Indices for its S&P CoreLogic Case-Shiller Indices for AugustFebruary showed a continuation of mid-single-digit home price appreciation nationally; meanwhile, mortgage rates declined over the course of the quarter, with the Freddie Mac survey 30-year mortgage rate endedfalling 18 basis points to end the third quarter of 2016 at 3.42%, down slightly from 3.48% at the end of the second quarter of 2016;4.14%;
Prepayment Rate Trends—Prepayment rates increased significantly throughoutremained low in the thirdfirst quarter, primarily driven by low mortgage rates throughoutwith the quarter;
Government Sponsored Enterprise, or "GSE," and Governmentmajority of Agency Developments—The Federal Housing Finance Agency, or "FHFA," and the GSEs continued to announce program and policy changes and clarifications intended to increase mortgage credit availability;mortgages no longer economically refinanceable;
Portfolio Overview and OutlookBolstered by high demand from both domestic and overseas investors, prices of 30-year fixed rate Agency RMBS increasedyield spreads widened over the course of the third quarter, even while interest rates rose slightly and overall prepayment rates increased. Indriven primarily by more hawkish indications from the overall Agency RMBS market, prepayment speeds rose significantlyFederal Reserve. Fixed-income credit spreads continued to tighten during the third quarter in response to sustained low mortgage rates. However, our Agency portfolio, which is concentrated in investments in specified pools with inherent prepayment protection characteristics, had a much lower quarter-over-quarter increase in prepayment speeds. Despite the higher prepayment speeds and heightened prepayment risk, yield spreads in most Agency mortgage sectors have not widened. Fundamentals underlying non-Agency RMBS, led by a stable housing market, continue to be strong and this sector also performed well over the courseearly part of the third quarter.first quarter, but began widening in early March following intermeeting commentary.
Federal Reserve and U.S. Monetary Policy
On September 21, 2016,March 15, 2017, the Federal Open Market Committee, or "FOMC,"FOMC announced that it would maintainraise the target range for the federal funds rate atby 0.25%, to 0.50%0.75%–1.00%. This marked the first back-to-back quarterly increases in the target range for the federal funds rate since 2006. In its SeptemberMarch statement following the meeting, the FOMC indicated that economic activity has picked up from the modestcontinued to expand at a moderate pace, seenand that solid job gains have contributed to a strengthening in the first half of the year, and the labor market has continued to strengthen.market. The FOMC also stated that inflation has increased in recent quarters and has moved closer to their two percent longer-run objective, although market-based measures of inflation compensation remain low. The FOMC reiterated that it expects that with gradual adjustments in the stance of monetary policy, the expansion of economic activity and the strengthening of thewill continue at a moderate pace, labor market conditions will continue.strengthen somewhat further, and inflation should stabilize around two percent over the medium term. Additionally, the FOMC indicated that it expects economic conditions to evolve in such a way that only gradual increases in the federal funds rate will be warranted, and that the federal funds rate is likely to remain, for some time, below prevailing longer run levels.
Over the course of the thirdfirst quarter, the 10-year U.S. Treasury yield increaseddecreased by 125 basis points, from 1.47%2.44% as of JuneDecember 30, 2016 to 1.59%2.39% as of September 30, 2016. March 31, 2017. Commentary from Federal Reserve officials over the intermeeting period between the February and March FOMC meetings contributed to increased market expectations of a decision to raise the target range for the federal funds rate at the March meeting. The 10-year U.S. Treasury yield increased 15 basis points during the two weeks prior to the March FOMC meeting, as investors reacted to comments made by Federal Reserve Chair Janet Yellen and other FOMC members, who all but assured investors that interest rates would be increased at the March FOMC meeting. After the meeting, assets rallied across markets, as the Federal Reserve left 2017–2018 guidance for additional target range increases unchanged from their December projections.
Finally, minutes from the March FOMC meeting indicated that a change to the Federal Reserve's reinvestment policy is likely later this year. While the Federal Reserve indicated that it expects to continue its reinvesting policy "until normalization of the level of the federal funds rate is well under way," uncertainty around when that condition would be satisfied weighed on asset valuations during the first quarter. The current pace of monthly reinvestments under this program is approximately $23 billion, and provides significant market support. A discontinuation of the program could have a meaningfully negative impact to prices. The FOMC minutes also showed that many participants emphasized that reducing the size of the balance sheet should be conducted in a passive and predictive manner.

Housing and Labor Market Statistics
Data released by S&P Dow Jones Indices for its S&P CoreLogic Case-Shiller Indices for February 2017 showed that, on average, home prices posted a 5.9% year-over-year increase for its 20-City Composite and a 5.2% year-over-year increase for its 10-City Composite, after seasonal adjustments.We believe that there remains substantial risknear-term home price trends are more likely to be driven by fundamental factors such as economic growth, mortgage rates, and affordability, rather than by technical factors such as foreclosure inventory.
On April 7, 2017, the U.S. Bureau of Labor Statistics, or "BLS," reported that, in March 2017, the U.S. unemployment rate was 4.5%, down from 5.0% a year earlier. The unemployment rate of 4.5% was the lowest level since May 2007 and represents a level generally considered consistent with an economy operating at or near full employment. In light of the drop in the labor force participation rate since the financial crisis, another, perhaps more relevant, measure of labor market conditions is employment growth. The BLS also reported that non-farm payrolls rose by 98,000 in March 2017, which was the weakest figure since last May, but suggests that the labor market is returning to a more sustainable pace of growth following large job gains in January and February. Over the past three months, job gains have averaged 178,000 per month.
Prepayment Rate Trends
As shown in the chart below, prepayment rates for non-specified pools have declined since year end. During the first quarter, the majority of Agency mortgages were no longer economically refinanceable. Prepayment rates for low loan balance specified pools increased slightly in the quarter.

Portfolio Overview and Outlook
General Market Overview
For most of the first quarter, both interest rate volatility and overall market volatility were low, but many measures of volatility increased towards the end of the quarter. The yield curve flattened over the course of the quarter as market participants ratcheted back their post-election expectations of economic growth and inflation in the U.S. economy. The 2-year U.S. Treasury yield rose 6 basis points to end the quarter at 1.25%, whereas the 10-year U.S. Treasury yield fell 5 basis points to 2.39%. Notably, global monetary policy has begun to diverge, as an interest rate hiking cycle is underway in the U.S. while the monetary policies of other major economies, including Europe and Japan, continue to be highly accommodative.
Fixed-income credit spreads continued to tighten during the early part of the first quarter, but began widening in early March following intermeeting commentary from several Federal Reserve governors, who expressed support for an imminent increase in the federal funds rate (which did in fact come to pass at the March 15th FOMC meeting), and who suggested that

tapering of the reinvestment program could begin later this year. These more hawkish indications from the Federal Reserve were the primary driver of the widening in Agency RMBS yield spreads over the course of the quarter. Meanwhile, non-Agency RMBS yield spreads remained flat to slightly tighter in March despite the movements in the broader credit markets, reflecting continued excellent fundamental and technical support in this sector.
Mortgage rates declined over the course of the first quarter, with the Freddie Mac survey 30-year mortgage rate falling 18 basis points to end the quarter at 4.14%. Similar to the fourth quarter, prepayment speeds remained low, with the majority of Agency mortgages no longer economically refinanceable. The Mortgage Bankers Association Refinance Index increased 12.4% in the first quarter, but remained well below the previously elevated levels of mid-2016.
We believe that several factors could put additional upward pressure on interest rates will increase from current levels, driven byin the near term, including a tightening of Federal Reserve monetary policy in response to employment and economic growth in the United States and other factors.States. The risk of rising interest rates reinforces the importance of our ability, subject to our qualifying and maintaining our qualification as a REIT, to hedge interest rate risk in both our Agency RMBS and non-Agency MBS portfolios using a variety of tools,instruments, including forward-settling To-Be-Announced Agency pass-through certificates, or "TBAs,"TBAs and interest rate swaps, and various other instruments. Additional uncertainty surrounds the Federal Reserve's timeline to curtail its reinvestment of principal payments from its U.S. Treasury security and Agency RMBS holdings. The current pace of monthly reinvestments under this program is approximately $42 billion, thus providing significant market support.swaps.

Housing and Mortgage Market Statistics
The following table demonstrates the decline in residential mortgage delinquencies and foreclosure inventory on a national level, as reported by CoreLogic in its July and August 2016 National Foreclosure Reports:
  As of

Foreclosure Inventory 351

(1)Seriously Delinquent Mortgages are ninety days and over in delinquency and include foreclosures and real estate owned, or "REO," property.
As the above table indicates, both the number of seriously delinquent mortgages and the number of homes in foreclosure have declined significantly over the past year. This decline supports the thesis that as many homeowners have re-established equity in their homes through recovering real estate prices, they have become less likely to become delinquent and default on their mortgages.
Monthly housing starts provide another indicator of market fundamentals. The following table shows the trailing three-month average housing starts for the periods referenced:

As of September 2016, average single-family housing starts during the trailing three months increased by 0.5%as compared to June 2016, while multi-family housing starts decreased by approximately 6.5% during the same period.
Through the third quarter of 2016, mid-single-digit home price appreciation continued, albeit at a somewhat more modest pace.Data released by S&P Dow Jones Indices for its S&P CoreLogic Case-Shiller Indices for August 2016 showed that, on average, home prices posted a 5.1% year-over-year increase for its 20-City Composite and a 4.3% year-over-year increase for its 10-City Composite, after seasonal adjustments.Additionally, as indicated in the table above, as of August 2016, the national inventory of foreclosed homes fell to 351,000 units, a 29.6% decline when compared to August 2015; this represented the fifty-eighth consecutive month with a year-over-year decline and the lowest level since October 2007. As a result, there are many fewer unsold foreclosed homes hanging over the housing market than there were a year ago. We believe that near-term home price trends are more likely to be driven by fundamental factors such as economic growth, mortgage rates, and affordability, rather than by technical factors such as shadow inventory. Shadow inventory represents the number of properties that are seriously delinquent, in foreclosure, or held as REO by mortgage servicers, but not currently listed on a multiple listing service.
On October 7, 2016, the U.S. Bureau of Labor Statistics, or "BLS," reported that, in September 2016, the U.S. unemployment rate was 5.0%, down from 5.1% a year earlier and at levels generally considered consistent with an economy near full employment. In light of the drop in the labor force participation rate since the financial crisis, another, perhaps more relevant, measure of labor market conditions is employment growth. The BLS also reported that non-farm payrolls rose by 156,000 in September 2016. This year through September 2016, job growth has averaged 178,000 per month, compared with an average of 229,000 per month for the comparable period in 2015.The change in total non-farm payroll employment for July was revised down from 275,000 to 252,000, and the change for August was revised up from 151,000 to 167,000. With these revisions, employment gains in July and August combined were 7,000 lower than previously reported. Over the past three months, job gains have averaged 192,000 per month.
While it is difficult to quantify the relationship between employment data and the housing and mortgage markets, we believe that current levels of unemployment and job creation are generally supportive of the housing market. While the housing market is also currently supported by low mortgage rates, it faces a number of potential headwinds. These include high interest rate volatility, the constraining effects of still-tight credit standards on both housing starts and new loan originations, and the uneven pace of the recovery of the U.S. economy.
Prepayment Rate Trends
Prepayment rates increased significantly during the third quarter of 2016, driven primarily by refinancing volume resulting from recent declines in mortgage rates. The Mortgage Bankers Association's Refinance Index, which measures refinancing application volumes, reached a one-year high on July 8, 2016. Prepayment rates slowed slightly in September, but

remained elevated.The post-Brexit vote decline in U.S. Treasury yields in late June sent already-low mortgage rates even lower in the third quarter, which spurred further increased refinancing activity.Because of the time that it takes for a refinancing application to result in an actual prepayment, the increase in prepayment rates was not fully reflected until August. Factors that continue to inhibit prepayment activity include: (i) home price declines during the financial crisis, which has left some borrowers with minimal or negative home equity; (ii) more restrictive underwriting guidelines, even for refinancings; and (iii) increased origination costs, especially related to underwriting and compliance. More recently, increases in mortgage banking industry staffing, improvements in technology, and modest relaxations in underwriting standards may be serving to offset a portion of these inhibitions on prepayment activity. The foregoing factors and developments have resulted in substantial variations in prepayment rates between Agency pools as a function of loan-to-value, or "LTV," ratio, loan balance, credit score, loan servicer, geography, property type, loan purpose, and other factors. In recognition of the importance of these underlying characteristics on prepayment behavior, the MBS market continues to promote the creation of "specified" Agency pools that emphasize or de-emphasize many of these characteristics, such as pools where the principal balance of every underlying mortgage loan is below $85,000. The Making Homes Affordable, or "MHA," refinancing program, which was initiated in response to the housing market crisis, has facilitated the origination of many of these kinds of specified Agency pools. We expect that the ongoing origination of Agency pools with a wide variety of loan characteristics will continue to create opportunities for us to exploit the resulting differences in prepayments.
While refinancing activity overall has been slower in recent periods relative to earlier periods when mortgage rates were at comparable levels, recent trends suggest an ongoing divergence between the refinancing behavior of lower balance loans and higher balance loans. As illustrated in the figure below, the average loan size of refinance applications has increased over the past three years, with a 35.4% increase from March 2013 through September 2016. This steady increase in average loan sizes of mortgage refinances is reflective of a number of changes related to borrower behavior and mortgage credit availability in recent years.
mbarefinanceindexchart.jpg
As shown in the figure above, higher loan balance borrowers tend to be more reactive to refinancing incentives, especially following steep declines in rates over a short period. After swift drops in mortgage rates in October 2014, January 2015, March 2015, the first six weeks of 2016 and late June 2016, the average refinanced loan size spiked, reflecting a surge in higher loan balance borrowers reacting to the recent decline in mortgage rates. This greater prepayment sensitivity for higher loan size borrowers is well established, and is due in part to greater awareness among such borrowers about refinancing opportunities, as well as greater absolute dollar incentives to refinance relative to lower loan size borrowers.

Moreover, while overall mortgage credit availability continues to increase from the depressed levels that followed the financial crisis, credit availability for higher loan size borrowers has been particularly improving recently. In the past two years, a number of the largest lenders, including Bank of America, JP Morgan, Wells Fargo, and PNC Bank, have noticeably loosened lending standards for jumbo mortgage loans typically sought by more affluent borrowers, including lowering minimum FICO requirements and raising maximum LTVs. Affluent borrowers have also generally experienced greater improvements in their creditworthiness, thanks to rising asset prices and a strong rebound in high-end home prices, especially in wealthier cities such as New York and San Francisco. Jumbo mortgage loans have been a rare bright spot for the non-Agency mortgage origination sector in recent years, and for good reason given the excellent credit performance of jumbo mortgage loans originated since the financial crisis. Many banks are also competing more vigorously for affluent customers, in an effort to cross-sell other financial products such as investment and brokerage services. This competition has resulted in a narrowing of the spread between jumbo mortgage rates and conforming mortgage rates, further increasing the relative refinancing incentive for jumbo mortgage loans.
While in the past few years more affluent and higher credit score borrowers have seen the largest increase in mortgage credit availability, more recently first time homebuyers, low-income borrowers, and borrowers in low income areas have started to benefit from an increase in high LTV mortgage lending programs targeted at these demographic groups. While recent growth is still relatively modest in these largely government-funded or non-profit-funded lending programs for less affluent borrowers, it may prefigure future expansions of credit to higher LTV borrowers.
In addition, since the financial crisis, financial reforms, including the Dodd-Frank Wall Street Reform and Consumer Protection Act, or "Dodd-Frank Act," and qualified mortgage, or "QM," mortgage guidelines, have dramatically increased the costs of underwriting, especially for niche products such as second lien and adjustable rate mortgages. Banks have reduced their footprint in the mortgage lending space as the scars of the financial crisis and higher capital requirements have increased the costs of doing business. More recently, market share has shifted to non-bank lenders, which do not face the same regulatory capital requirements as banks for servicing mortgages, and which possess superior technology to better assist borrowers in making more efficient refinancing decisions.
The shift in mortgage banking industry market share to more efficient non-bank lenders has contributed to the increase in aggregate prepayment speeds. For example, Quicken Loans Inc., or "Quicken," has become one of the leaders in efficient mortgage refinancing in recent years. As shown in the figure below, prepayment speeds on Quicken loans are among some of the fastest in the industry; however, Quicken may not continue to be the outlier that it used to be, as improved technology continues to be adopted by other lenders. In the figure below, we show the 3-month constant prepayment rate, or "CPR," for Freddie Mac 30-year fixed rate mortgages with original loan balances between $200,000 and $400,000, loan ages between 12 and 47 months, and with interest rates that are 50 to 100 basis points above then current market rates. While in recent years Quicken prepayment speeds were consistently as much as 10 to 20 CPR faster than those of other servicers during prepayment spikes, this differential has almost entirely evaporated in the past few months. Ultimately, technology-driven, industrywide increases in prepayment efficiency may put pressure on MBS prices and/or reduce the excess yield spread enjoyed by MBS investors.
As improved technology spreads, we believe that the lending industry will change in two important ways. First, more efficient mortgage origination should mean that some cost savings will be passed on to borrowers. Smaller balance loans, which are disproportionately used by lower income borrowers, should respond the most from a reduction in the fixed components of origination costs. Second, overall prepayment behavior should continue to grow in efficiency, as demonstrated by the higher prepayment speeds of mortgage loans serviced by Quicken and other non-bank mortgage originators. Assessing the ongoing evolution of these industrywide changes, including studying servicer-specific trends, is of increasing importance in investing in both specified pools and TBAs.

GSE/Government Agency Developments
On July 7, 2016, the FHFA released "An Update on Implementation of the Single Security and the Common Securitization Platform," which detailed progress made by the two GSEs to date on developing and operating a Common Securitization Platform. The report also outlined expectations for future stated goals, including the issuance by Fannie Mae and Freddie Mac of a single mortgage-backed security, or "Single Security." According to the timeline in the report, issuance of a Single Security is expected to occur in 2018. The goal of establishing a Single Security is to create a single, liquid market that can be maintained over time, for MBS backed by GSE-issued fixed-rate mortgage loans. The improved liquidity of the Single Security should also help improve the liquidity of the TBA market and aid the FHFA in meeting its statutory obligation of providing for the liquidity of the national housing finance market.
On August 25, 2016, the FHFA announced that the two GSEs will implement a new streamlined refinancing program aimed at borrowers with high LTV ratios. The new program, which will not be available until October 2017, will be available for GSE borrowers who are current on their mortgage but are presently unable to refinance because their LTV ratio exceeds the maximum limits currently allowed by the GSEs. The FHFA's stated objective in implementing this program is to enable high LTV borrowers to refinance when rates are low, thus making their mortgages more affordable, and in turn reducing credit risk exposure for the GSEs. In order to ensure that high LTV borrowers who are eligible for the Home Affordable Refinance Program ("HARP") will not be without a refinancing option before the new program becomes available, the FHFA has created a bridge to the new program by extending the HARP program through September 30, 2017. The new program should have a muted impact on prepayment speeds because only a small amount of loans not currently utilizing HARP will have high enough LTV ratios to qualify.
To date, no definitive legislation has been enacted with respect to a possible unwinding of the GSEs or a material reduction in their roles in the U.S. mortgage market. There have been several proposals offered by members of Congress, including the Corker-Warner bill introduced in June 2013, the Johnson-Crapo bill introduced in March 2014, the Partnership to Strengthen Homeownership Act introduced in July 2014, and a Senate draft bill introduced in May 2015 by Senator Richard Shelby that pushes for increased credit risk transfers to private investors. To date, the GSEs have engaged predominantly in "second-loss" risk sharing transactions, where the GSEs bear losses on their mortgage pools up to a capped amount first, before private investors bear any losses. Furthermore, these risk sharing transactions to date have generally been "back-end" transactions, where the GSE seeks to offload its risk only after it has actually issued guarantees on a defined pool of mortgages. Under the Shelby bill, not only would the GSEs be required to engage in significant and increasing levels of risk sharing transactions generally, but for the first time the GSEs would be required to engage both in "first-loss" risk sharing transactions

and in "front-end" risk sharing transactions. Many of these proposed bills could potentially increase private capital flows to the mortgage sector while reducing taxpayer risk. Though it appears unlikely that any of these bills will be passed in their current form, features may be incorporated into future proposals.
Portfolio Overview and Outlook
General Market Overview
During the third quarter, U.S. interest rates trended somewhat higher and many measures of implied volatility reached multi-year lows. The large and frequent swings in interest rates that characterized the early part of 2016 were comparatively absent in the third quarter. Bias toward accommodative monetary policy by global central banks, in response to continued sluggish growth, contributed to the lower volatility and increased investor appetite for risk-taking. Negative yields persisted throughout the quarter for many high quality sovereign bonds maintaining the global shortage of high quality, positive-yielding liquid fixed income investments. As a result, the higher yields and favorable liquidity offered by Agency RMBS continued to fuel demand from investors, especially those in search of high credit quality assets. This demand helped support Agency RMBS prices despite rising interest rates and increasing prepayment speeds. Many credit sensitive U.S. fixed income sectors, including non-Agency RMBS and high-yield corporate bonds, also performed well in the quarter, driven by investor demand for yield.
Since its December 2015 initial increase in the target range for the federal funds rate, which followed a long period of monetary policy easing actions, the Federal Reserve has not announced any additional interest rate increases. Concerns around a global economic slowdown, as well as mixed data regarding the state of the U.S. economy, have led the Federal Reserve to delay the timing and expected pace of increases in the target range. However, as market developments occur, speculation about when the Federal Reserve will resume its plan to increase rates continues to be a significant factor in the direction of interest rates.
The yield curve continued to flatten over the course of the third quarter, although less dramatically than it had in the second quarter. The 10-year U.S. Treasury yield increased 12 basis points to 1.59%, while the 2-year U.S. Treasury yield increased 18 basis points to 0.76%. Despite the rise in interest rates, the drop in interest rate volatility helped keep mortgage rates low over the course of the quarter; the Freddie Mac survey 30-year mortgage rate actually declined 6 basis points over the course of the quarter, and fell as low as 3.41% on July 7th, its lowest level since May 2013. In response, the Mortgage Bankers Association Refinance Index, which tracks the volume of mortgage loan refinancing applications, reached a one-year high on July 8, 2016.
Agency
As of September 30, 2016,March 31, 2017, the value of our long Agency bond portfolio was $1.215$1.214 billion, as compared to $1.206 billion as of June 30, 2016 and $1.211$1.208 billion as of December 31, 2015.2016.
Our Agency RMBS portfolio isconsisted principally comprised of "specified pools." Specified pools are fixed rate Agency pools consisting of mortgages with special characteristics, such as pools comprised ofmortgages with low loan balance mortgages, pools comprised ofbalances, mortgages backed by investor properties, pools containing mortgages originated through the government-sponsored MHA refinancing programs, and pools containing mortgages with various other characteristics.
Bolstered by high demand fromDuring the first quarter, both domesticrealized and overseas investors, prices of 30-year fixed rateimplied volatility remained low, but yield spreads for Agency RMBS increasedwidened. Agency RMBS investors are becoming increasingly focused on the timing and mechanism of the Federal Reserve's discontinuation of its current policy of reinvesting principal payments from its Agency RMBS holdings. While the Federal Reserve has indicated that it expects to continue its reinvesting policy "until normalization of the level of the federal funds rate is well under way," uncertainty around when that condition would be satisfied weighed on asset valuations during the first quarter. Despite the anticipated reduced support from the Federal Reserve, we do not expect that Agency RMBS yield spreads will widen substantially, as they did during the 2013 "Taper Tantrum," largely because the investor base for Agency RMBS has changed substantially since then. Agency RMBS ownership has largely shifted away from investors such as the GSEs, certain money managers, and mortgage REITs whose activities, including delta-hedging and utilization of high degrees of leverage, tend to amplify price swings during periods of high volatility.
During the first quarter, mortgage rates remained relatively elevated from their pre-election levels, and prepayment rates declined, as many borrowers did have not an economic incentive to refinance their mortgages. The lower day count of the first quarter and the impact of winter seasonality were also factors contributing to the overall decline in prepayments. Since the generic pools that underlie TBAs tend to be more prepayment-sensitive than specified pools, the favorable decline in overall prepayment rates helped TBAs outperform specified pools over the course of the third quarter, even while interest rates rose slightly and overall prepayment rates increased. Overall prepayment rates reached their highest levels since 2012, and exceeded most sell-side estimates. Newer mortgages originated by non-bank lenders have been prepaying at a particularly fast pace. Strong borrower credit, high mortgage loan balances, and enhanced originator/servicer technology and infrastructure each played a role in the increased prepayment speeds.
Although specified pools with prepayment protection features also experienced a quarter-over-quarter increase in overall prepayment speeds, this increase was significantly less than that of generic pools, and accountedfirst quarter. This dampened our results for the relative outperformance of specified pools relative to generic pools during the quarter. Specified pools include loans with low principal balances, for example. Such loans continue to show much more muted prepayment responses to lower mortgage rates. Our Agency RMBS portfolio, which remains concentrated in specified pools, was well insulated from the large increase in generic pool prepayment rates during the quarter. We believefirst quarter, given that specified pools will continue to outperform generic pools as the presence of the Federal Reserve (which focuses its purchases on generic pools) shrinks in the Agency RMBS market and as newer vintage Agency RMBS prepayment speeds remain high. In the current climate of elevated prepayment speeds, relative pricing among the many sectors of the Agency RMBS market, including both the generic "TBA" sectors and the many sub-sectors of the specified pool market, is often highly inefficient, and so careful asset selection remains of paramount importance.
During the third quarter, higher short-term interest rates lowered the costTBA short positions are a major component of our interest rate swap hedges, but for technical reasons the higher rates did not lead to materially higher Agency RMBS repo borrowing costs. As a result of changeshedging portfolio.

in money market fund regulations, there has been a significant investor shift away from "prime" money market funds, which under the new regulations are now susceptible to daily changes in their share prices, and into "government" money market funds. Because government money market funds are among the biggest providers of Agency RMBS repo, the increased assets of these funds has resulted in an increase in the supply of Agency RMBS repo financing, thereby putting downward pressure on the cost of Agency RMBS repo, and largely offsetting the increase in short-term interest rates.
For the quarter ended September 30, 2016, we had total net realized and unrealized gains of $2.6 million, or $0.29 per share, on our aggregate Agency RMBS portfolio, while we had total net realized and unrealized losses of $(0.4) million, or $(0.04) per share, on our interest rate hedging portfolio, including U.S. Treasury securities. Average pay-upsPay-ups on our specified pools increased to 1.07% as of September 30, 2016, from 1.03% as of June 30, 2016.decreased slightly quarter over quarter. Pay-ups are price premiums for specified pools relative to their TBA counterparts. Average pay-ups on our specified pools decreased to 0.68% as of March 31, 2017, from 0.70% as of December 31, 2016. Notwithstanding the slight decline of the first quarter, we believe that the evolving landscape, including the Federal Reserve's eventual withdrawal from the TBA market, may provide substantial support to pay-ups. In addition, technological advances in the mortgage origination and servicing industry have tended to have a much greater impact on non-specified pools as compared to specified pools. We believe that this trend will continue, ultimately driving greater investor demand for specified pools relative to TBAs.
For the quarter ended March 31, 2017, we had total net realized and unrealized losses of $(5.4) million, or $(0.59) per share, on our aggregate Agency RMBS portfolio. Slightly lower asset valuations during the period led to the modest net losses. During the third quarter we continued to hedge interest rate risk, primarily through the use of interest rate swaps and short positions in TBAs, and to a lesser extent, short positions in U.S. Treasury securities. For the quarter, we had total net realized and unrealized losses of $(1.2) million, or $(0.13) per share, on our interest rate hedging portfolio. Within our hedging portfolio, our interest rate swaps generated net gains as swap rates increased across the yield curve, but those gains were offset by losses on our short positions in TBAs, U.S. Treasury securities, and futures. During the quarter, TBA roll prices increased and longer maturity U.S. Treasury yields declined, most notably in March, thereby leading to losses. In our hedging portfolio, the relative

proportion (based on 10-year equivalents2) of TBA short positions increased quarter over quarter relative to interest rate swaps. We believe that it is important to be able to hedge our Agency RMBS portfolio using a variety of instruments, including TBAs.
1"10-year equivalents" for a group of positions represent the amount of 10-year U.S. Treasury securities that would experience a similar change in market value under a standard parallel move in interest rate risk. TBAs underperformed specified pools during the quarter as more investors sought pools with prepayment protection. Because we held a net short position in TBAs against our long position in specified pools, this underperformance of TBAs relative to specified pools benefited our results for the quarter. To the extent that prepayment rates remain elevated, we believe that the underperformance of generic pools relative to specified pools will persist.rates.
We actively traded our Agency RMBS portfolio during the quarter in order to capitalize both on sector rotation opportunities and trading opportunities. Our portfolio turnover for the quarter was 24%21% (as measured by sales and excluding paydowns), and we capturedhad net realized gainslosses of $2.7$(2.5) million, excluding hedges. Our portfolio selection continues to be informed by mortgage industry trends—including significant enhancements in technology that are helping streamline the origination process—and we note that refinancing capacity remains high, with employment in the mortgage industry near a post-financial crisis high.
During the thirdfirst quarter, we continued to focus our Agency RMBS purchasing activity primarily on specified pools, especiallyparticularly those with higher coupons. As of September 30, 2016, theThe weighted average coupon on our fixed rate specified pools was 3.9%, as compared to 4.0% for June 30, 2016. As of September 30, 2016,unchanged from the sizeprior quarter. Even though we net purchased assets during the first quarter in our Agency RMBS portfolio, the slight decline in asset prices caused the total market value of our Agency RMBS portfolio wasas of March 31, 2017 to remain relatively unchanged, at $1.2 billion, as compared to June 30,December 31, 2016. Our Agency RMBS portfolio continues to include a small allocation to Agency IOs. We also pared backIOs, and similar to the fourth quarter of 2016, we increased our holdings of reverse mortgagethose during the first quarter. Some of the IOs that we purchased were backed by seasoned Ginnie Mae pools following their significant spread tightening throughoutthat have demonstrated some level of "burnout." Burnout often occurs after periods of high prepayments, when the quarter. We continuemix of loans remaining in an RMBS pool becomes more concentrated in loans that tend to view reverse mortgage pools (and derivatives thereon) as an attractive and inefficiently priced asset class. Overall, we believe that there remains a heightened risk of substantial interest rate and mortgage prepayment volatility in the near term, thus reinforcing the importance of our ability to hedge our Agency RMBS portfolio usingprepay more slowly; burnout can reflect a variety of tools,factors, including TBAs.the behavior of individual borrowers and overall trends in the mortgage banking industry. Our Agency IOs not only contribute to our portfolio in the form of their yields, but they also inherently serve as portfolio market value hedges in a rising interest rate environment.
We expect to continue to target specified pools that, taking into account their particular composition and based on our prepayment projections:projections, should: (1) should generate attractive yields relative to other Agency RMBS and U.S. Treasury securities, (2) should have less prepayment sensitivity to government policy shocks, and/or (3) should create opportunities for trading gains once the market recognizes their value, which for newer pools may come only after several months, when actual prepayment experience can be observed. We believe that our research team, proprietary prepayment models, and extensive databases remain essential tools in our implementation of this strategy.

Our net Agency premium as a percentage of the fair value of our long Agency RMBSspecified pool holdings is one metric that we use to measure ourthe overall prepayment risk.risk of our specified pool portfolio. Net Agency premium represents the total premium (excess of market value over outstanding principal balance) on long Agency RMBSour specified pool holdings less the total premium on related net short TBA positions. The lower our net Agency premium, the less we believe we arethat our specified pool portfolio is exposed to market-wide increases in Agency RMBS prepayments. As of September 30, 2016,March 31, 2017, our net Agency premium as a percentage of fair value on long Agency RMBSof our specified pool holdings was approximately 5.1%3.4%, as compared to 5.2%3.6%, as of June 30,December 31, 2016. Excluding TBA positions used to hedge our long Agency RMBS portfolio,specified pool holdings, our Agency premium as a percentage of fair value was approximately 7.8%5.1% and 7.7%5.4% as of September 30, 2016March 31, 2017 and June 30,December 31, 2016, respectively. Our Agency premium percentage and net Agency premium percentage may fluctuate from period to period based on a variety of factors, including market factors such as interest rates and mortgage rates, and, in the case of our net Agency premium percentage, based on the degree to which we hedge prepayment risk with short TBAs. We believe that our focus on purchasing pools with specific prepayment characteristics provides a measure of protection against prepayments.
We believe that our adaptive and active style of portfolio management is well suited to the current MBS market environment, which continues to be shaped by heightened prepayment risk,shifting central bank and government policies, regulatory changes, and developing technologies.
Non-Agency
As of September 30, 2016, the value ofMarch 31, 2017, our longinvestment in non-Agency portfolioRMBS was $17.9$16.0 million as compared to $22.8 million as of June 30, 2016 and $31.4$19.4 million as of December 31, 2015.2016.
Non-Agency
Our non-Agency RMBS performed well duringin the third quarter.first quarter, driven by net carry and realized and unrealized gains. As the case has been for some time, the fundamentals underlying non-Agency RMBS, led by a stable housing market, continue to be strong. Our non-Agency portfolio benefited from strong yields, appreciation from our held positions, and net realized gains from positions sold. On a quarter-over-quarter

basis, our non-Agency RMBS portfolio declineddecreased in size.size, as we sold securities that we believed had become fully valued. To the extent that more attractive entry points develop in non-Agency RMBS, we may increase our capital allocation to this sector.
Financing
Over the course of the third quarter our cost of repo financing was effectively unchanged relative to the second quarter.increased as LIBOR increased. Our weighted average borrowing ratecost for the quarterthree month period ended September 30, 2016March 31, 2017 was 0.71%0.94% as compared to 0.70%0.81% for the quarterthree month period ended June 30,December 31, 2016. As an indirect consequence of money market reform rules that became effective in October 2016, higher short-term interest rates in the third quarter did not lead to higher repo costs. Under the new rules which were promulgated by the Securities Exchange Commission, prime institutional money-market funds, which invest in short-term debt securities and cater to institutions such as retirement-plan sponsors, will have to allow their prices to fluctuate daily based on the current market value of their holdings, rather than maintaining a fixed net asset value, or NAV, of $1 a share. This floating-NAV rule does not apply to government and retail money market funds. As a result of these new rules, there has been a significant increase in the AUM of government money market funds and a corresponding decrease in AUM of prime money market funds. Because government money market funds are among the biggest providers of Agency RMBS repo, the increased AUM of these entities resulted in an increase in available Agency repo financing, thereby putting downward pressure on the cost of repo.
While large banks still dominate the repo market, non-bank firms, not subject to the same regulations as banks, are becoming more active in providing repo financing. The vast majority of our outstanding repo financing is still provided by banks and bank affiliates; however, in limited amounts, we have also entered into repo agreements with non-bank dealers. In general, we continue to see strong appetite and competitive terms from both types of lenders.
Our debt-to-equity ratio was to 8.1:8.4:1 as of September 30, 2016March 31, 2017 as compared to 8.6:1 as of June 30, 2016, and 8.4:8.5:1 as of December 31, 2015.2016. Adjusted for unsettled security purchases and sales, our debt-to-equity ratio was 8.2:1 as of September 30, 2016March 31, 2017 and 8.1:8.3:1 as of each of June 30, 2016 and December 31, 2015.2016. Our leverage ratio may fluctuate period over period based on portfolio management decisions, market conditions, and the timing of security purchase and sale transactions.
Critical Accounting Policies
Our consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America, or "U.S. GAAP." Entities in which we have a controlling financial interest, through ownership of the majority of the entities' voting equity interests, or through other contractual right that give us control, are consolidated by us. All inter-company balances and transactions have been eliminated.
Certain of our critical accounting policies require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. We believe that all of the decisions and assessments upon which our consolidated financial statements are based were reasonable at the time made based upon information available to us at that time. We rely on our Manager and Ellington's experience and analysis of historical and current market data in order to arrive at what we believe to be reasonable estimates. See Note 2 of the notes to our consolidated financial statements included in this Quarterly Report on Form 10-Q for a complete discussion of our significant accounting policies. We have identified our most critical accounting policies to be the following:
Valuation: For financial instruments that are traded in an "active market," the best measure of fair value is the quoted market price. However, many of our financial instruments are not traded in an active market. Therefore, management generally uses third-party valuations when available. If third-party valuations are not available, management uses other valuation techniques, such as the discounted cash flow methodology. Summary descriptions, for the various categories of financial instruments, of the valuation methodologies management uses in determining fair value of our financial instruments are detailed in Note 2 of the notes to our consolidated financial statements. Management utilizes such methodologies to assign a good faith fair value (the estimated price that, in an orderly transaction at the valuation date, would be received to sell an asset, or paid to transfer a liability, as the case may be) to each such financial instrument.
See the notes to our consolidated financial statements for more information on valuation techniques used by management in the valuation of our assets and liabilities.
Accounting for Securities: Investments in mortgage-backed securities are recorded on trade date. We have chosen to make a fair value election pursuant to ASC 825-10, Financial Instruments, for our mortgage-backed securities portfolio. Electing the fair value option allows us to record changes in fair value in our Consolidated Statement of Operations, which, in our 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. As such, the mortgage-backed securities are recorded at fair value on our Consolidated Balance Sheet and the period change in fair value is recorded in current period earnings on our Consolidated Statement of Operations as

a component of Change in net unrealized gains (losses) on securities.
Realized gains or losses on sales of mortgage-backed securities are included in Net realized gains (losses) on securities on the Consolidated Statement of Operations, and are recorded at the time of disposition. The cost of positions sold is calculated based on identified cost. Principal write-offs are generally treated as realized losses.

Interest Income: Coupon interest income on investment securities is accrued based on the outstanding principal balance and the current coupon rate on each security. We amortize purchase premiums and accrete purchase discounts on our fixed income investments using the effective interest method.
Our accretion of discounts and amortization of premiums on securities for U.S. federal and other tax purposes is likely to differ from the accounting treatment under U.S. GAAP of these items as described above.
See the Note 2 of the notes to our consolidated financial statements for more information on the assumptions and methods that we use to amortize purchase premiums and accrete purchase discounts.
Income Taxes: We made an election to be taxed as a REIT for U.S. federal income tax purposes. As a REIT, we generally are not subject to corporate-level federal and state income tax on net income we distribute to our shareholders. To qualify as a REIT, we must meet a number of organizational and operational requirements, including a requirement to distribute at least 90% of our taxable income to our shareholders. Even if we qualify as a REIT, we may be subject to certain federal, state, local and foreign taxes on our income and property and to federal income and excise taxes on our undistributed taxable income. 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.
We follow the authoritative guidance on accounting for and disclosure of uncertainty on tax positions, which requires management to determine whether a tax position is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals or litigation processes, based on the technical merits of the position. For uncertain tax positions, the tax benefit to be recognized is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. The Company did not have any unrecognized tax benefits resulting from tax positions related to the current period or to 2016, 2015, 2014, or 2013 (its open tax years). In the normal course of business, we may be subject to examination by federal, state, local, and foreign jurisdictions, where applicable, for the current period, 2016, 2015, 2014, and 2013 (our open tax years). We may take positions with respect to certain tax issues which depend on legal interpretation of facts or applicable tax regulations. Should the relevant tax regulators successfully challenge any such positions; we might be found to have a tax liability that has not been recorded in the accompanying consolidated financial statements. Also, management's conclusions regarding the authoritative guidance may be subject to review and adjustment at a later date based on changing tax laws, regulations, and interpretations thereof. There were no amounts accrued for penalties or interest as of or during the periods presented in the consolidated financial statements included in this Quarterly Report on Form 10-Q.
"Emerging Growth Company" Status: On April 5, 2012, the Jumpstart Our Business Startups Act, or the "JOBS Act," was signed into law. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for qualifying public companies. Because we qualify as an "emerging growth company," we may, under Section 7(a)(2)(B) of the Securities Act delay adoption of new or revised accounting standards applicable to public companies until such standards would otherwise apply to private companies. We may take advantage of this extended transition period until the first to occur of the date that we (i) are no longer an "emerging growth company" or (ii) affirmatively and irrevocably opt out of this extended transition period. We have elected to take advantage of the benefits of this extended transition period. As a result, our financial statements may not be comparable to those of other public companies that comply with such new or revised accounting standards. Until the date that we are no longer an "emerging growth company" or affirmatively and irrevocably opt out of the exemption provided by Securities Act Section 7(a)(2)(B), upon issuance of a new or revised accounting standard that applies to our financial statements and that has a different effective date for public and private companies, we will disclose the date on which adoption is required for non-emerging growth companies and the date on which we will adopt the recently issued accounting standard.

(1)Represents the dollar amount (not shown in thousands) per $100 of current principal of the price or cost for the security.
(2)Excludes Agency IOs.
The vast majority of our capital is allocated to our Agency RMBS strategy, which includes investments in Agency pools and Agency CMOs. Within this strategy, we generally target Agency RMBS pools that, taking into account their particular composition and based on our prepayment projections: (1) should generate attractive yields relative to other Agency RMBS and U.S. Treasury securities, (2) should have less prepayment sensitivity to government policy shocks and/or (3) should create opportunities for trading gains once the market recognizes their value, which for newer pools may come only after several months when actual prepayment experience can be observed. As of both September 30, 2016March 31, 2017 and December 31, 2015,2016, investments in non-Agency RMBS constituted a relatively small portion of our total investments.
Our most prevalent method of financing RMBS is through short-term repurchase agreements, which generally have maturities of 180 days or less. The weighted average lives of the RMBS that we own are generally much longer. Consequently, the weighted average term of our repurchase agreement financings will almost always be substantially shorter than the expected average maturity of our RMBS. This mismatch in maturities, together with the uncertainty of RMBS prepayments, and other potential changes in timing and/or amount of cash flows on our RMBS assets, creates the risk that changes in interest rates will cause our financing costs with respect to our RMBS to increase relative to the income on our RMBS over the term of our investments.

Pursuant to our hedging program, we engage in a variety of interest rate hedging activities that are designed to reduce the interest rate risk with respect to the liabilities incurred to acquire or hold RMBS. These interest rate hedges generally seek to reduce the interest rate sensitivity of our liabilities or, in other words, reduce the volatility of our financing cost over time attributable to interest rate changes. Our interest rate hedging transactions may include:
Interest rate swaps (a contract exchanging a variable rate for a fixed rate, or vice versa);
Interest rate swaptions (options to enter into interest rate swaps at a future date);
TBA forward contracts on Agency pass-through certificates;
Short sales of U.S. Treasury securities;
Eurodollar and U.S. Treasury futures; and
Other derivatives.
We generally enter into these transactions to offset the potential adverse effects of rising interest rates on short-term repurchase agreements. Our repurchase agreements generally have maturities of up to 180 days and carry interest rates that are determined by reference to LIBOR or correlated benchmark rates for those same periods. As each then-existing fixed rate repo borrowing matures, it will generally be replaced with a new fixed rate repo borrowing based on market interest rates established at that future date.
In the case of interest rate swaps, most of our agreements are structured such that we receive payments based on a variable interest rate and make payments based on a fixed interest rate. The variable interest rate on which payments are received is generally calculated based on various reset mechanisms for LIBOR. To the extent that our future repo borrowing costs continue to be highly correlated with LIBOR, our swap agreements help to reduce the variability of our overall repo borrowing costs, thus reducing risk to the extent we hold fixed rate assets that are financed with repo borrowings.
In the case of TBAs, most of our positions are short TBA positions with a negative duration, meaning that as interest rates rise, the value of the short position increases, so these positions serve as a hedge against increases in interest rates. In the event that interest rates rise, the increase in value of the short TBA position serves to offset corollary increases in our current and/or future borrowing costs under our repurchase agreements. While we primarily use TBAs to hedge interest rate risk, from time to time we also hold net long positions in certain TBA securities as a means of acquiring exposure to Agency RMBS. Our ability to engage in TBA transactions may be limited by our intention to remain qualified as a REIT.
As of September 30, 2016,March 31, 2017, as part of our interest rate hedging program, we also held short positions in U.S. Treasury securities, with a total principal amount of $76.5$83.0 million and a fair value of $77.3$79.5 million. As of December 31, 2015,2016, we also held short positions in U.S. Treasury securities, with a total principal amount of $79.6$78.6 million and a fair value of $78.4$74.2 million.

The composition and relative mix of instruments we use to hedge various risks may vary from period to period given the amount of our liabilities outstanding or anticipated to be entered into, the overall market environment and our view as to which instruments best enable us to execute our hedging goals.

We finance our assets with what we believe to be a prudent amount of leverage, which will vary from time to time based upon the particular characteristics of our portfolio, availability of financing, and market conditions. Because our strategy is flexible, dynamic, and opportunistic, our overall leverage will vary over time. As of September 30, 2016March 31, 2017 and December 31, 2015,2016, our total debt-to-equity ratio was 8.18.4 to 1 and 8.48.5 to 1, respectively. Collateral transferred with respect to our outstanding repo borrowings as of September 30, 2016both March 31, 2017 and December 31, 20152016 had an aggregate fair value of $1.2 billion and $1.3 billion, respectively.billion. Adjusted for unsettled security purchases and sales, our debt-to-equity ratio was 8.2 to 1 and 8.18.3 to 1 as of September 30, 2016March 31, 2017 and December 31, 2015,2016, respectively. Our leverage ratio may fluctuate period over period based on portfolio management decisions, market conditions, and the timing of security purchase and sale transactions.
Shareholders' Equity
As of September 30, 2016,March 31, 2017, our shareholders' equity decreased to $143.3$140.1 million from $144.9$141.7 million as of December 31, 2015.2016. This decrease principally consisted of dividends declared of $11.4 million and the repurchase of common shares of $0.2$3.7 million, partially offset by net income of $9.9 million and share based compensation of $0.1$2.1 million. As of September 30, 2016,March 31, 2017, our book value per share was $15.70$15.35 as compared to $15.86$15.52 as of December 31, 2015.2016.

Core Earnings
Core Earnings consists of net income (loss), excluding realized and change in net unrealized gains and (losses) on securities and financial derivatives, and, if applicable, items of income or loss that are of a non-recurring nature. Core Earnings includes net realized and change in net unrealized gains (losses) associated with payments and accruals of periodic payments on interest rate swaps. Our interest income is subject to fluctuations based on adjustments to premium amortization as a result of changes in prepayments of our Agency RMBS (accompanied by a corresponding offsetting adjustment to realized and unrealized gains and losses). We refer to this adjustment as a "Catch-up Premium Amortization Adjustment." Adjusted Core Earnings represents Core Earnings excluding Catch-up Premium Amortization Adjustment consists of Core Earnings but excludes the effect of the Catch-up Premium Amortization Adjustment on interest income. Core Earnings and Adjusted Core Earnings excluding Catch-up Premium Amortization Adjustment are supplemental non-GAAP financial measures. We believe that Core Earnings and Adjusted Core Earnings excluding Catch-up Premium Amortization Adjustment provide information useful to investors because they are metrics that we use to assess our performance and to evaluate the effective net yield provided by the portfolio. Moreover, one of our objectives is to generate income from the net interest margin on the portfolio, and Core Earnings and Adjusted Core Earnings excluding Catch-up Premium Amortization Adjustment are used to help measure the extent to which this objective is being achieved. However, because Core Earnings and Adjusted Core Earnings excluding Catch-up Premium Amortization Adjustment are incomplete measures of our financial results and differ from net income (loss) computed in accordance with U.S. GAAP, they should be considered as supplementary to, and not as substitutes for, net income (loss) computed in accordance with U.S. GAAP.

Results of Operations for the Three Month Periods Ended March 31, 2017 and 2016
Net Income (Loss)
The increase in net income (loss) period over period was principally due to net realized and net change in unrealized gains on securities and derivatives infor the three month period ended September 30, 2016March 31, 2017 as compared to the three month period ended March 31, 2016 was principally due to an increase in net interest income and a decline in combined net realized and net change in unrealized losses on securities and financial derivatives infor the three month period ended September 30, 2015. Higher asset prices duringMarch 31, 2017. A larger, higher-yielding portfolio led to the increase in net interest income for the three month period ended September 30,March 31, 2017, and the three month period ended March 31, 2016 fueledwas marked by increasing investor demand for high credit quality and attractive yielding assets, led to net realized and unrealized gains on our portfolio. Sharply lowerperiods of significant volatility in interest rates which led to net realized and unrealized losses on our derivatives duringfinancial derivatives. For the three month period ended September 30, 2015. Our financial derivatives are principally comprised of instruments used to hedgeMarch 31, 2017, interest rate risk. Duringvolatility was significantly lower as compared to the three monthsame period ending September 30, 2016, net realized and unrealized gains on our portfolio of mortgage-backed securities more than offset the impact of losses on our interest rate hedges. Lower net interest income resulted in a commensurate decline in our Core Earnings.2016.
Interest Income
Our portfolio as of both September 30,each of March 31, 2017 and 2016 and 2015 consisted primarily of Agency RMBS, and to a lesser extent, non-Agency RMBS. Before interest expense, we earned approximately $7.0$12.2 million and $11.3$9.6 million in interest income on these securities for the three month periods ended September 30,March 31, 2017 and 2016, and 2015, respectively. The period-over-period decreaseincrease in interest income resulted from lower yieldshigher average holdings on our Agency RMBS and lowerhigher average holdingsyields on both our Agency and non-Agency RMBS. Some of the variability in our interest income and portfolio yields is due to Catch-up Premium Amortization Adjustment. The adjustment is calculated as of the beginning of each quarter based on our then assumptions about cashflows and prepayments, and can vary significantly from quarter to quarter. For the first quarter of 2017, we had a positive Catch-up Premium Amortization Adjustment of approximately $2.6 million, which increased our interest income. Excluding the Catch-up Premium Amortization Adjustment, the weighted average yield of our portfolio was 2.99% for the first quarter of 2017. By comparison, for the first quarter of 2016 the Catch-up Premium Amortization Adjustment increased interest income by only approximately $0.3 million. Excluding this Catch-up Premium Amortization Adjustment, the weighted average yield on our portfolio for the first quarter of 2016 would have been 3.04%.

Interest Expense
For each of the three month periods ended September 30,March 31, 2017 and 2016, and 2015, the majority of interest expense that we incurred was related to our repo borrowings, which we use to finance our assets. We also incur interest expense in connection with our short positions in U.S. Treasury securities. Our total interest expense for the three month period ended September 30, 2016March 31, 2017 was $2.3$3.2 million, of which $2.0$2.8 million represented interest expense on our repo borrowings and approximately $0.3$0.4 million represented interest expense related primarily to our short positions in U.S. Treasury securities. Our total interest expense for the three month period ended September 30, 2015March 31, 2016 was $1.6$2.1 million, of which $1.4$1.8 million represented interest expense on our repo borrowings and approximately $0.2$0.3 million represented interest expense related primarily to our short positions in U.S. Treasury securities. The period-over-period increase in our total interest expense resulted mainly from higher rates on our repo borrowings. In December 2015, for the first time in several years, the Federal Reserve increased the target range for the federal funds rate, to a range of 0.25%-to-0.50%, up 25 basis points from the prior range of 0.0%-to-0.25%; this increase has caused repo borrowing rates to increase. Our average outstanding repo borrowings for the three month period ended September 30, 2016March 31, 2017 was $1.14$1.19 billion, resulting in an annualized average cost of funds of 0.71%0.94%. Our average outstanding repo borrowings for the three month period ended September 30, 2015March 31, 2016 was $1.24$1.14 billion, resulting in an annualized average cost of funds of 0.43%0.62%.

As an alternative cost of funds measure, we add to our repo interest cost the net periodic amounts paid or payable by us on our interest rate swaps and the interest expense that we incur on our short positions in U.S. Treasury securities, and express the total as an annualized percentage of our average outstanding borrowings. The total of our net periodic expense paid or payable under our interest rate swaps and our interest expense on our short positions in U.S. Treasury securities was $0.9 million for the three month period ended September 30, 2016,March 31, 2017, or 0.30%0.29% of our average outstanding repo borrowings, on an annualized basis, thereby resulting in an annualized average cost of funds including interest rate swaps and short positions in U.S. Treasury securities of 1.01%1.23%. The total of our net periodic expense paid or payable under our interest rate swaps and the interest expense on our short positions in U.S. Treasury securities was $2.4$1.7 million for the three month period ended September 30, 2015,March 31, 2016, or 0.77%0.59% of our average outstanding borrowings, on an annualized basis, thereby resulting in an annualized average cost of funds including interest rate swaps and short positions in U.S. Treasury securities of 1.21%. This metric does not take into account other instruments that we use to hedge interest rate risk, such as TBAs, swaptions, and futures.
Management Fees
For both of the three month periods ended September 30,March 31, 2017 and 2016, and 2015, our management fee expense was approximately $0.5 million and $0.6 million, respectively. The decrease in management fees period over period was due to our smaller capital base.
Other Operating Expenses
Other operating expenses, as presented above, include professional fees, compensation expense, and various other expenses incurred in connection with the operation of our business. Other operating expenses for each of the three month

periods ended September 30, 2016 and 2015 were approximately $0.7 million. Our expense ratio, which represents our management fees and other operating expenses as a percentage of our average shareholders' equity, was 3.5% on an annualized basis for the three month period ended September 30, 2016, as compared to 3.3% for the three month period ended September 30, 2015. The increase in our annualized expense ratio was primarily due to a decrease in our average shareholders' equity for the three month period ended September 30, 2016 as compared to the three month period ended September 30, 2015.
Other Income (Loss)
Other income (loss) consists of net realized and net change in unrealized gain (losses) on securities and financial derivatives. For the three month period ended September 30, 2016, other income was $3.0 million, and consisted of net realized and change in net unrealized gains of $3.7 million on our securities, primarily our Agency RMBS, partially offset by net realized and change in net unrealized losses of approximately $(0.7) million on our financial derivatives. Over the course of the quarter, and in light of their liquidity and their yield relative to other high credit quality investments such as sovereign debt, demand for Agency RMBS increased. This demand provided support to prices and yield spreads. In addition, during the quarter, as measured by sales and excluding paydowns, we turned over approximately 24% of our Agency RMBS portfolio and, as a result, for the three month period ended September 30, 2016, we generated net realized gains of $2.7 million on our Agency RMBS portfolio. Interest rate volatility was relatively low during the three month period ended September 30, 2016.
Other income (loss) for the three month period ended September 30, 2015 was $(13.2) million and consisted of net realized and change in net unrealized losses of $(18.7) million on our financial derivatives, partially offset by net realized and change in net unrealized gains of approximately $5.5 million on our securities, primarily Agency RMBS.

Core Earnings
Core Earnings consists of net income (loss), excluding realized and change in net unrealized gains and (losses) on securities and financial derivatives, and, if applicable, items of income or loss that are of a non-recurring nature. Core Earnings includes net realized and change in net unrealized gains (losses) associated with payments and accruals of periodic payments on interest rate swaps. Our interest income is subject to fluctuations based on adjustments to premium amortization as a result of changes in prepayments of our Agency RMBS (accompanied by a corresponding offsetting adjustment to realized and unrealized gains and losses). We refer to this adjustment as a "Catch-up Premium Amortization Adjustment." Core Earnings excluding Catch-up Premium Amortization Adjustment consists of Core Earnings but excludes the effect of the Catch-up Premium Amortization Adjustment on interest income. Core Earnings and Core Earnings excluding Catch-up Premium Amortization Adjustment are supplemental non-GAAP financial measures. We believe that Core Earnings and Core Earnings excluding Catch-up Premium Amortization Adjustment provide information useful to investors because they are metrics that we use to assess our performance and to evaluate the effective net yield provided by the portfolio. Moreover, one of our objectives is to generate income from the net interest margin on the portfolio, and Core Earnings and Core Earnings excluding Catch-up Premium Amortization Adjustment are used to help measure the extent to which this objective is being achieved. However,

because Core Earnings and Core Earnings excluding Catch-up Premium Amortization Adjustment are incomplete measures of our financial results and differ from net income (loss) computed in accordance with U.S. GAAP, they should be considered as supplementary to, and not as substitutes for, net income (loss) computed in accordance with U.S. GAAP.

Net Income (Loss)
The increase in net income (loss) for the nine month period ended September 30, 2016 as compared to the nine month period ended September 30, 2015 was principally due to a decrease in net realized and unrealized losses on securities and financial derivatives for the nine month period ended September 30, 2016. Each nine-month period included periods of high volatility in interest rates which led to significant swings in net realized and unrealized gains and losses on our securities and financial derivatives. Our period-over-period net interest income declined as a result of our smaller portfolio of securities held, as well as an increase in our cost of repo. Reduced net interest income resulted in a commensurate decline in our Core Earnings.
Interest Income
Our portfolio as of both September 30, 2016 and 2015 consisted primarily of Agency RMBS, and to a lesser extent, non-Agency RMBS. Before interest expense, we earned approximately $24.0 million and $31.4 million in interest income on these securities for the nine month periods ended September 30, 2016 and 2015, respectively. The period-over-period decrease in interest income resulted from lower average holdings on both our Agency and non-Agency RMBS and lower average yields on our Agency RMBS.

Interest Expense
For the nine month periods ended September 30, 2016 and 2015, the majority of interest expense that we incurred was related to our repo borrowings, which we use to finance our assets. We also incur interest expense in connection with our short positions in U.S. Treasury securities. Our total interest expense for the nine month period ended September 30, 2016 was $6.6 million, of which $5.8 million represented interest expense on our repo borrowings and approximately $0.8 million represented interest expense related primarily to our short positions in U.S. Treasury securities. Our total interest expense for the nine month period ended September 30, 2015 was $4.4 million, of which $3.7 million represented interest expense on our repo borrowings and approximately $0.7 million represented interest expense related primarily to our short positions in U.S. Treasury securities. The period-over-period increase in our total interest expense resulted mainly from higher rates on our repo borrowings. In December 2015, for the first time in several years, the Federal Reserve increased the target range for the federal funds rate, to a range of 0.25%-to-0.50%, up 25 basis points from the prior range of 0.0%-to-0.25%; this increase has caused repo borrowing rates to increase. Our average outstanding repo borrowings for the nine month period ended September 30, 2016 was $1.14 billion, resulting in an annualized average cost of funds of 0.68%. Our average outstanding repo borrowings for the nine month period ended September 30, 2015 was $1.24 billion, resulting in an annualized average cost of funds of 0.39%.

The total of our net periodic expense paid or payable under our interest rate swaps and our interest expense on our short positions in U.S. Treasury securities was $3.9 million for the nine month period ended September 30, 2016, or 0.46% of our average outstanding repo borrowings on an annualized basis, thereby resulting in an annualized average cost of funds including interest rate swaps and short positions in U.S. Treasury securities of 1.13%. The total of our net periodic expense paid or payable under our interest rate swaps was $6.4 million for the nine month period ended September 30, 2015, or 0.68% of our average outstanding borrowings on an annualized basis, thereby resulting in an annualized average cost of funds including interest rate swaps of 1.08%. This metric does not take into account other instruments that we use to hedge interest rate risk, such as TBAs, swaptions, and futures.
Management Fees
For the nine month periods ended September 30, 2016 and 2015, our management fee expense was approximately $1.60.5 million and $1.8 million, respectively. The decrease in management fees period over period was due to our smaller capital base..
Other Operating Expenses
Other operating expenses, as presented above, include professional fees, compensation expense, and various other expenses incurred in connection with the operation of our business. Other operating expenses for the ninethree month periods ended September 30,March 31, 2017 and 2016 and 2015 were approximately $2.30.7 million and $2.2$0.8 million, respectively.

Other income (loss) consists of net realized and net change in unrealized gain (losses) on securities and financial derivatives. For the ninethree month period ended September 30, 2016,March 31, 2017, other loss was $(3.9)$(5.8) million, and consisted of net realized and change in net unrealized losses of $(27.3)$(0.5) million on our financial derivatives and approximately $(5.3) million on our securities, primarily our Agency RMBS. The three month period ended March 31, 2017 included slight declines in asset valuations, mainly on our Agency RMBS as yield spreads widened. For the three month period ended March 31, 2017, as measured by sales and excluding paydowns, we turned over approximately 21% of our Agency RMBS portfolio and, as a result, we generated net realized losses of $(2.5) million on our Agency RMBS portfolio. During the period, we took advantage of the slight drop in pay-ups for specified pools by rotating a portion of our portfolio into what we believe are higher quality specified pools at attractive valuations. Within our hedging portfolio, our interest rate swaps generated net gains as swap rates increased across the yield curve, but those gains were offset by losses on our short positions in TBAs, U.S. Treasury securities, and futures. During the quarter, TBA roll prices increased and longer maturity U.S. Treasury yields declined, most notably in March, thereby leading to losses. Additionally, as we use short TBAs as a major component of our interest rate hedging portfolio, the relative underperformance of specified pools in comparison to TBAs dampened our results for the first quarter.
Other income (loss) for the three month period ended March 31, 2016 was $(6.5) million and consisted of net realized and change in net unrealized losses of $(18.1) million on our financial derivatives partially offset by net realized and change in net unrealized gains of approximately $23.4$11.6 million on our securities, primarily our Agency RMBS. The nine month period ended September 30, 2016 included periods of significant interest rate volatility. Overall,Sharply lower interest rates declined over the course of the nine month period, and both prices and pay-ups on our specified Agency pools increased. While we had net realized and unrealized gains on our Agency RMBS, these were more than offset by net losses incurred on our interest rate hedges, although in the second and third quarters, Agency RMBS kept much better pace with interest rate swaps than they had in the first quarter. In addition, during the nine month period ended September 30, 2016, as measured by sales and excluding paydowns, we turned over approximately 102% of our Agency RMBS portfolio and, as a result, we generated net realized gains of $9.2 million on our Agency RMBS portfolio. Since interest rates swaps comprise a significant component of our interest rate hedges, we have had to actively adjust our interest rate hedges as interest rates have moved sharply higher and lower. This increased interest rate swap adjustment activity led to losses on our interest rate swaps over the period.
Other income (loss) for the nine month period ended September 30, 2015 was $(24.0) million and consisted of net realized and change in net unrealized losses of $(25.1) million on our financial derivatives, partially offset by net realized and change in net unrealized gains of approximately $1.1 million on our securities, principally our Agency RMBS. The first nine months of 2015 were marked by significant interest rate volatility. Over the course of 2015, interest rates moved both sharply higher and sharply lower, and overall, resulted in net losses on our financial derivatives, most notably our interest rate swaps.hedges.
Liquidity and Capital Resources
Liquidity refers to our ability to meet our cash needs, including repaying our borrowings, funding and maintaining RMBS and other assets, paying dividends, and other general business needs. Our short-term (one year or less) and long-term liquidity requirements include acquisition costs for assets we acquire, payment of our management fee, compliance with margin requirements under our repurchase agreements, TBA and other financial derivative contracts, repayment of repurchase agreement borrowings to the extent we are unable or unwilling to extend our repurchase agreements, the payment of dividends, and payment of our general operating expenses. Our capital resources primarily include cash on hand, cash flow from our investments (including monthly principal and interest payments received on our RMBS and proceeds from the sale of RMBS), borrowings under repurchase agreements, and proceeds from equity offerings. We expect that these sources of funds will be sufficient to meet our short-term and long-term liquidity needs.
We borrow funds in the form of repurchase agreements. The terms of these borrowings under our Master Repurchase Agreements, or "MRAs," generally conform to the terms in the standard master repurchase agreement as published by the Securities Industry and Financial Markets Association as to repayment and margin requirements. In addition, each lender may require that we include supplemental terms and conditions to the standard master repurchase agreement. Typical supplemental terms and conditions include the addition of or changes to provisions relating to margin calls, net asset value requirements, cross default provisions, certain key person events, changes in corporate structure, and requirements that all controversies related to the repurchase agreement be litigated in a particular jurisdiction. These provisions may differ for each of our lenders.
As of each of September 30, 2016March 31, 2017 and December 31, 2015,2016, we had $1.2 billion, outstanding under our repurchase agreements. As of September 30, 2016,March 31, 2017, our outstanding repurchase agreements were with thirteen counterparties.

Amount at risk represents the aggregate excess, if any, for each counterparty of the fair value of collateral held by such counterparty over the amounts outstanding under repurchase agreements. The following table reflects counterparties for which the amounts at risk relating to our repurchase agreements was greater than 5% of shareholders' equity as of September 30, 2016March 31, 2017 and December 31, 2015.2016.

The amounts borrowed under our repurchase agreements are generally subject to the application of "haircuts." A haircut is the percentage discount that a repo lender applies to the market value of an asset serving as collateral for a repo borrowing, for the purpose of determining whether such repo borrowing is adequately collateralized. As of September 30, 2016both March 31, 2017 and December 31, 2015,2016, the weighted average contractual haircut applicable to the assets that serve as collateral for our outstanding repo borrowings was 4.8% and 4.7%, respectively..

We may declare dividends based on, among other things, our earnings, our financial condition, the REIT qualification requirements of the Internal Revenue Code of 1986, as amended, our working capital needs and new opportunities. The declaration of dividends to our shareholders and the amount of such dividends are at the discretion of our Board of Trustees.

For the ninethree month period ended September 30, 2016,March 31, 2017, our operating activities provided net cash of $26.5$30.6 million and our investing activities providedused net cash of $52.2$3.3 million. Our repo activity used to finance our purchase of securities (including repayments, in conjunction with the sales of securities, of amounts borrowed under our repurchase agreements) used net cash of $63.8$19.7 million. Thus our operating and investing activities, when combined with our net repo financing activities, provided net cash of $14.9$7.7 million. We used $11.9$3.7 million to pay dividends and $0.2 million for the repurchase of common shares.dividends. As a result of these activities, there was an increase in our cash holdings of $2.9$4.0 million from $40.2$33.5 million as of December 31, 20152016 to $43.0$37.5 million as of September 30, 2016.March 31, 2017.
For the ninethree month period ended September 30, 2015,March 31, 2016, our operating activities provided net cash of $9.7$10.8 million and our investing activities provided net cash of $98.1$83.4 million. Our repo activity used to finance our purchase of securities (including repayments, in conjunction with the sales of securities, of amounts borrowed under our repurchase agreements) used net cash of $97.2$88.9 million. Thus our operating and investing activities, when combined with our net repo financing activities, provided net cash of $10.6$5.4 million for the ninethree month period ended September 30, 2015.March 31, 2016. We used $15.1$4.1 million to pay dividends and $0.3$0.2 million for the repurchase of common shares. As a result of these activities, there was a decreasean increase in our cash holdings of $4.8$1.1 million from $45.2$40.2 million as of December 31, 20142015 to $40.5$41.2 million as of September 30, 2015.March 31, 2016.

On August 13, 2013, our Board of Trustees approved the adoption of a $10 million share repurchase program. The program, which is open-ended in duration, allows us to make repurchases from time to time on the open market or in negotiated transactions. Repurchases are at our discretion, subject to applicable law, share availability, price and our financial performance, among other considerations. During the ninethree month period ended September 30, 2016,March 31, 2017, we purchased 17,920did not purchase any of our common shares at an average price per share of $10.94 for an aggregate cost of approximately $0.2 million.shares.
Based on our current portfolio, amount of free cash on hand, debt-to-equity ratio and current and anticipated availability of credit, we believe that our capital resources will be sufficient to enable us to meet anticipated short-term and long-term liquidity requirements.
We are not required by our investment guidelines to maintain any specific debt-to-equity ratio, and we believe that the appropriate leverage for the particular assets we hold depends on the credit quality and risk of those assets, as well as the general availability and terms of stable and reliable financing for those assets.
Contractual Obligations and Commitments
We are a party to a management agreement with our Manager. Pursuant to that agreement, our Manager is entitled to

receive a management fee based on shareholders' equity, reimbursement of certain expenses and, in certain circumstances, a termination fee. Such fees and expenses do not have fixed and determinable payments. For a description of the management agreement provisions, see Note 9 to our consolidated financial statements.
We enter into repurchase agreements with third-party broker-dealers whereby we sell securities to such broker-dealers at agreed-upon purchase prices at the initiation of the repurchase agreements and agree to repurchase such securities at predetermined repurchase prices and termination dates, thus providing the broker-dealers with an implied interest rate on the funds initially transferred to us by the broker-dealers. We may enter into reverse repurchase agreements with third-party broker-dealers whereby we purchase securities under agreements to resell at an agreed-upon price and date. In general, we most often will enter into reverse repurchase agreement transactions in order to effectively borrow securities that we can then deliver to counterparties to whom we have made short sales of the same securities. The implied interest rates on the repurchase agreements and reverse repurchase agreements we enter into are based upon competitive market rates at the time of initiation. Repurchase agreements and reverse repurchase agreements that are conducted with the same counterparty may be reported on a net basis if they meet the requirements of ASC 210-20, Balance Sheet, Offsetting. As of each of September 30, 2016March 31, 2017 and December 31, 2015,2016, there were no repurchase agreements and reverse repurchase agreements reported on a net basis on the Consolidated Balance Sheet.
As of September 30, 2016 and DecemberMarch 31, 20152017 we had $1.2 billion of outstanding borrowings with thirteen counterparties.
Off-Balance Sheet Arrangements
As of September 30, 2016 and DecemberMarch 31, 2015,2017, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Further, we have not guaranteed any obligations of unconsolidated entities nor do we have any commitment or intent to provide funding to any such entities. As such, we are not materially exposed to any market, credit, liquidity, or financing risk that could arise if we had engaged in such relationships.
Inflation
Virtually all of our assets and liabilities are interest rate-sensitive in nature. As a result, interest rates and other factors influence our performance far more so than does inflation. Changes in interest rates do not necessarily correlate with inflation rates or changes in inflation rates. Our activities and balance sheet are measured with reference to historical cost and/or fair market value without considering inflation.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
The primary components of our market risk are related to interest rate risk, prepayment risk, and credit risk. We seek to actively manage these and other risks and to acquire and hold assets that we believe justify bearing those risks, and to maintain capital levels consistent with those risks.
Interest Rate Risk
Interest rates are highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations, and other factors beyond our control. We are subject to interest rate risk in connection with most of our assets and liabilities. For some securities in our portfolio, the coupon interest rates on, and therefore also the values of, such securities are highly sensitive to interest rate movements, such as inverse floating rate RMBS, which benefit from falling interest rates. Our repurchase agreements generally have maturities of up to 180 days and carry interest rates that are determined by reference to LIBOR or similar short-term benchmark rates for those same periods. Whenever one of our fixed rate repo borrowings matures, it will generally be replaced with a new fixed rate repo borrowing based on market interest rates prevailing at such time. Subject to qualifying and maintaining our qualification as a REIT and our exclusion from registration under the Investment Company Act, we opportunistically hedge our interest rate risk by entering into interest rate swaps, TBAs, U.S. Treasury securities, Eurodollar and U.S. Treasury futures, and other instruments. In general, such hedging instruments are used to offset the large majority of the interest rate risk we estimate to arise from our repurchase agreement indebtedness generally associated with our Agency RMBS positions. Hedging instruments may also be used to offset a portion of the interest rate risk arising from our repurchase agreement liabilities associated with non-Agency RMBS positions, if any.
In addition to measuring and mitigating the risk related to changes in interest rates with respect to the generally shorter-term liabilities we incur to acquire and hold generally longer-lived RMBS, we also monitor the effect of changes in interest rates on the discounted present value of our portfolio of assets and liabilities. The following sensitivity analysis table shows the estimated impact on the fair value of our portfolio segregated by certain identified categories as of September 30, 2016,March 31, 2017, assuming a static portfolio and immediate and parallel shifts in interest rates from current levels as indicated below.

Our analysis of interest rate risk is derived from Ellington's proprietary models as well as third-party information and analytics. Many assumptions have been made in connection with the calculations set forth in the table above and, as such, there can be no assurance that assumed events will occur or that other events will not occur that would affect the outcomes. For example, for each hypothetical immediate shift in interest rates, assumptions have been made as to the response of mortgage prepayment rates, the shape of the yield curve, and market volatilities of interest rates; each of the foregoing factors can significantly and adversely affect the fair value of our interest rate sensitive instruments.
The above analysis utilizes assumptions and estimates based on management's judgment and experience, and relies on financial models, which are inherently imperfect; in fact, different models can produce different results for the same securities. While the table above reflects the estimated impacts of immediate parallel interest rate increases and decreases on specific categories of instruments in our portfolio, we intend to actively trade many of the instruments in our portfolio and intend to diversify our portfolio to reflect a portfolio comprised primarily of Agency RMBS, and, to a lesser extent, non-Agency RMBS and mortgage-related assets. Therefore, our current or future portfolios may have risks that differ significantly from those of our September 30, 2016

March 31, 2017 portfolio estimated above. Moreover, the impact of changing interest rates on fair value can change significantly when interest rates change by a greater amount than the hypothetical shifts assumed above. Furthermore, our portfolio is subject to many risks other than interest rate risks, and these additional risks may or may not be correlated with changes in interest rates. For all of the foregoing reasons and others, the table above is for illustrative purposes only and actual changes in interest rates would likely cause changes in the actual fair value of our portfolio that would differ from those presented above, and such differences might be significant and adverse. See "Special Note Regarding Forward-Looking Statements."
Prepayment Risk
Prepayment risk is the risk of change, whether an increase or a decrease, in the rate at which principal is returned in respect to mortgage loans underlying RMBS, including both through voluntary prepayments and through liquidations due to defaults and foreclosures. This rate of prepayment is affected by a variety of factors, including the prevailing level of interest rates as well as economic, demographic, tax, social, legal, and other factors. Changes in prepayment rates will have varying effects on the different types of securities in our portfolio, and we attempt to take these effects into account in making asset management decisions. Additionally, increases in prepayment rates may cause us to experience losses on our investment in interest-only securities, or "IOs""IOs," and inverse interest only securities, or "IIOs," as these securities are extremely sensitive to prepayment rates. Finally, prepayment rates, besides being subject to interest rates and borrower behavior, are also substantially affected by government policy and regulation.
Credit Risk
We are subject to credit risk in connection with our assets, especially our non-Agency RMBS. Credit losses on real estate loans underlying our non-Agency RMBS can occur for many reasons, including, but not limited to, poor origination practices, fraud, faulty appraisals, documentation errors, poor underwriting, legal errors, poor servicing practices, weak economic conditions, decline in the value of homes, special hazards, earthquakes and other natural events, over-leveraging of the borrower on the property, reduction in market rents and occupancies and poor property management services in the case of rented homes, changes in legal protections for lenders, reduction in personal income, job loss, and personal events such as

divorce or health problems. Property values are subject to volatility and may be affected adversely by a number of factors, including, but not limited to, national, regional, and local economic conditions (which may be adversely affected by industry slowdowns and other factors), local real estate conditions (such as an oversupply of housing), changes or continued weakness in specific industry segments, construction quality, age and design, demographic factors, and retroactive changes to building or similar codes. For mortgage-related instruments, the two primary components of credit risk are default risk and severity risk.
Default Risk
Default risk is the risk that borrowers will fail to make principal and interest payments on their mortgage loans. Subject to qualifying and maintaining our qualification as a REIT and our exclusion from registration under the Investment Company Act, we may selectively attempt to mitigate our default risk by, among other things, opportunistically entering into credit default swaps and total return swaps. These instruments can reference various RMBS indices, corporate bond indices, or corporate entities, such as publicly traded REITs. We also rely on third-party mortgage servicers to mitigate our default risk, but such third-party mortgage servicers may have little or no economic incentive to mitigate loan default rates.
Severity Risk
Severity risk is the risk of loss upon a borrower default on a mortgage loan underlying our RMBS. Severity risk includes the risk of loss of value of the property underlying the mortgage loan as well as the risk of loss associated with taking over the property, including foreclosure costs. We rely on third-party mortgage servicers to mitigate our severity risk, but such third-party mortgage servicers may have little or no economic incentive to mitigate loan loss severities. Such mitigation efforts may include loan modification programs and prompt foreclosure and property liquidation following a default.
