Accounting Policies [Abstract]
Organization and Significant Accounting Policies	Organization and Business Description Orchid Island Capital, Inc. (“Orchid” or the “Company”), was incorporated in Maryland on August 17, 2010 for the purpose of creating and managing a leveraged investment portfolio consisting of residentia l mortgage-backed securities (“RMBS ”). From incorporation t o February 20, 2013 , Orchid was a whol ly owned subsidiary of Bimini Capital Management, Inc. (“Bimini”). Orchid began operations on November 24, 2010 (the date of commencement of operations). From incorporation through November 24, 2010, Orchid’s only activity was the issuance of common stoc k to Bimini. On August 2, 2017, Orchid entered into an equity distribution agreement (the “August 2017 Equity Distribution Agreement”) with two sales agents pursuant to which the Company may offer and sell, from time to time, up to an aggregate amount of $125,000,000 of shares of the Company’s common stock in transactions that are deemed to be “at the market” offerings and privately negot iated transactions. Through September 30, 2019 , the Company issued a total of 15,123,178 shares under the August 2017 Equity Distribution Agreement for aggregate gross proceeds of approximately $125.0 million, and net proceeds of approximately $123.1 million, ne t of commissions and fees . On July 30, 2019, Orchid entered into an underwriting agreement (the “Underwriting Agreement”) with Morgan Stanley & Co. LLC, Citigroup Global Markets Inc. and J.P. Morgan Securities LLC, as representatives of the underwriters named therein, relating to the offer and sale of 7,00 0,000 shares of our common stock at a price to the public of $6.55 per share. The underwriters purchased the shares pursuant to the Underwriting Agreement at a price of $6.3535 per share. The closing of the offering of 7,000,000 shares of common stock occu rred on August 2, 2019, with net proceeds to us of approximately $44. 2 million after deduction of underwriting discounts and commissions and other estimated offering expenses payable by us. Basis of Presentation and Use of Estimates The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q a nd Article 8 of Regulation S- X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair p resentat ion have been included. Operating results for the nine and three month period ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year end ing December 31, 2019 . The balance sheet at December 31, 2018 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the financial statements and footnotes thereto inclu ded in the Company’s A nnual R eport on Form 10-K for the year ended December 31, 2018 . The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and l iabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The significant estimat es affecting the accompanying financial statements are the fair values of RMBS and derivatives . Variable Interest Entities (“VIEs”) We obtain interests in VIEs through our investments in mortgage-backed securities. Our interests in these VIEs are passive in nature and are not expected to result in us obtaining a controlling financial interest in these VIEs in the future. As a result, we do not consolidate these VIEs and we account for our interest in these VIEs as mortgage-backed securities. See Note 2 for additional information regarding our investments in mortgage-backed securities. Our maximum exposure to loss for these VIEs is t he carrying value of the mortgage-backed securities. Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents include cash on deposit with financial institutions and highly liquid investments with original maturities of three months or less at the time of purchase . Restricted cash includes cash pledged as collateral for repurchase agreements and other borrowings, and interest rate swaps and other derivative instruments. The following table provides a reconciliation of cash, cash equiva lents, and restricted cash reported within the statement of financial position that sum to the total of the same such amounts shown in the statement of cash flows. (in thousands) September 30, 2019 December 31, 2018 Cash and cash equivalents $ 147,428 $ 108,282 Restricted cash 54,788 17,981 Total cash, cash equivalents and restricted cash $ 202,216 $ 126,263 The Company maintains cash balances at three banks and excess margin on account with two exchange clearing members. At times, balances may exceed federally insured limits. The Company has not experienced any losses related to these balances. The Federal De posit Insurance Corporation insures eligible accounts up to $250,000 per depositor at each financial institution. At September 30, 2019 , the Company’s cash deposits exceeded federally insured limits by approximately $118.8 million. Restricted cash balan ces are uninsured, but are held in separate customer accounts that are segregated from the general funds of the counterparty. The Company limits uninsured balances to only large, well-known banks and exchange clearing members and believes that it is not exposed to any significant credit risk on cash and cash equivalents or restricted cash balances. Mortgage-Backed Securities The Company invests primarily in mortgage pass-through (“PT”) residential mortgage backed certificates issued by Freddie Mac, Fann ie Mae or Ginnie Mae (“RMBS” ) , collateralized mortgage obligations (“CMOs”) , interest- only (“IO”) securities and inverse interest- only (“IIO”) securities representing interest in or obligations backed by pools of RMBS . We refer to IO and IIO securities as structured RMBS. T he Company has elected to account for its investment in RMBS under the fair value option. Electing the fair value option require s the Company to record changes in fair value in the statement of operati ons, which, in management’s view, more appropriately reflects the results of our operations for a particular reporting period and is consistent with the underlying economics and how the portfolio is managed. The Company records RMBS transactions on the tr ade date. Security purchases that have not settled as of the balance sheet date are included in the RMBS balance with an offsetting liability recorded, whereas securities sold that have not settled as of the balance sheet date are removed from the RMBS bal ance with an offsetting receivable recorded. Fair value is defined as the price that would be received to sell the asset or paid to transfer the liability in an orderly transaction between market participants at the measurement date. The fair value measurement assumes that the transaction to sell th e asset or transfer the liability either occurs in the principal market for the asset or liability, or in the absence of a principal market, occurs in the most advantageous market for the asset or liability. Estimated fair values for RMBS are based on inde pendent pricing sources and/or third party broker quotes, when available. Income on PT RMBS securities is based on the stated interest rate of the security. Premiums or discounts present at the date of purchase are not amortized. Premium lost and discoun t accretion resulting from monthly principal repayments are reflected in unrealized gains (losses) on RMBS in the statements of operations. For IO securities, the income is accrued based on the carrying value and the effective yield. The difference between income accrued and the interest received on the security is characterized as a return of investment and serves to reduce the asset’s carrying value. At each reporting date, the effective yield is adjusted prospectively for future reporting period s based o n the new estimate of prepayments and the contractual terms of the security. For IIO securities, effective yield and income recognition calculations also take into account the index value applicable to the security. Changes in fair value of RMBS during eac h reporting period are recorded in earnings and reported as unrealized gains or losses on mortgage-backed securities in the accompanying statements of operations. Derivative Financial Instruments The Company uses derivative instruments to manage interest rate risk, facilitate asset/liability strategies and manage other exposures, and it may continue to do so in the future. The principal instruments that the Company has used to date are Treasury Note (“T-Note”) , Fed Funds and Eurodollar futures contracts, interest rate swaps, options to enter in interest rate swaps (“interest rate swaptions”) and “to-be-announced” (“TBA”) securities transactions, but the Company may enter into other derivatives in the future. The Company accounts for TBA securities as derivative instruments if either the TBA securities do not settle in the shortest period of time possible or if the Company cannot assert that it is probable at inception of the TBA transaction, or throughout its term, that it will take physical delivery of the Agency RMBS for a long position, or make delivery of the Agency RMBS for a short position, upon settlement of the trade. Gains and losses associated with TBA securities transactions are reported in gain (lo ss) on derivative instruments in the accompanying statements of operations. Derivative instruments are carried at fair value, and changes in fair value are recorded in earnings for each period. The Company’s derivative financial instruments are not design ated as hedge accounting relationships, but rather are used as economic hedges of its portfolio assets and liabilities. Holding d erivatives creates exposure to credit risk related to the potential for failure on the part of counterparties and exchanges to honor their commitments. In addition, the Company may be required to post collateral based on any decli nes in the market value o f the d erivatives. In the event of default by a counterparty, the Company may have difficulty recovering its collateral and may not receive payments provided for under the terms of the agreement . To mitigate this risk, the Company uses only well-establis hed comme rcial banks and exchanges as counterparties. Financial Instruments The fair value of financial instruments for which it is practicable to estimate that value is disclosed , either in the body of the financial statements or in the accompanying notes. RMBS, Eurodollar and T-Note futures contracts, interest rate swaps, interest rate swaptions and TBA securities are accounted for at fair value in the balance sheets. The methods and assumptions used to estimate fair value for these instruments are p resented in Note 12 of the financial statements. The estimated fair value of cash and cash equivalents, restricted cash, accrued interest receivable, receivable for securities sold, other assets, due to affiliates, repurchase agreements , payable for unsettled securities purchased, accrued interest payable and other liabilities generally approximates their carrying values as of September 30, 2019 and December 31, 2018 due to the short-term nature of these financial instruments. Repurchase Agreements The Company finances the acquisition of the majority of its RMBS through the use of repurchase agreements under master repurchase agreements. Repurchase agreements are accounted for as collateralized financing transactions, which are carried at their contract ual amounts, including accrued interest, as specified in the respective agreements. Manager Compensation The Company is externally managed by Bimini Advisors, LLC ( th e “Manager” or “Bimini Advisors”) , a Maryland limited liability company and wh olly-owned subsidiary of Bimini . The Company’s management agreement with the Manager provides for payment to the Manager of a management fee and reimbursement of certain operating expenses, which are accrued and expensed during the period for which they ar e earned or incurred. Refer to Note 13 for the terms of the management agreement. Earnings Per Share Basic earnings per share (“EPS”) is calculated as net income or loss attributable to common stockholders divided by the weighted average number of sha res of common stock outstanding or subscribed during the period. Diluted EPS is calculated using the treasury stock or two-class method, as applicable, for common stock equivalents, if any. However, the common stock equivalents are not included in computin g diluted EPS if the result is anti-dilutive. Income Taxes Orchid has qualified and elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code ”). REITs are generally not subject to federal income tax on their REIT taxable income provided that they distribute to their stockholders at least 90% of their REIT taxable income on an annual basis. In addition, a REIT must meet other provisions of the Code to retain its tax status. Orchid assesses the likelihood, based on their technical merit, that uncertain tax positions will be sustained upon examination based on the facts, circumstances and information available at the end of each period. All of Orchid’s tax positions are catego rized as highly certain. There is no accrual for any tax, interest or penalties related to Orchid’s tax position assessment. The measurement of uncertain tax positions is adjusted when new information is available, or when an event occurs that requires a change. Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss model). ASU 2016-13 is effective for fiscal years, and for interim periods within those years, beginning after December 15, 2019. Early application is permitted for fiscal periods beginnin g after December 15, 2018. The Company does not expect that the adoption of this ASU will have a significant effect on its financial statements.

Disclosure of Repurchase Agreements [Abstract]
Repurchase Agreements and Other Borrowings	NOTE 3 . REPURCHASE AGREEMENTS AND OTHER BORROWINGS The Company pledges certain of its RMBS as collateral under repurchase agreements with financial institutions. Interest rates are generally fixed based on prevailing rates corresponding to the terms of the borrowings , and interest is generally paid at the termination of a borrowing . If the fair value of the pledged securities declines, lenders will typically require the Company to post additional collateral or pay down borrowings to re-establish agreed upon collateral requirements, referred to as "margin ca lls." Similarly, if the fair value of the pledged securities increases, lenders may release collateral back to the Company. As of September 30, 2019 , the Company had met all margin call requirements. As of September 30, 2019 and December 31, 2018 , the Company’s repurchase agreements had remaining maturities as summarized below: ($ in thousands) OVERNIGHT BETWEEN 2 BETWEEN 31 GREATER (1 DAY OR AND AND THAN LESS) 30 DAYS 90 DAYS 90 DAYS TOTAL September 30, 2019 Fair market value of securities pledged, including accrued interest receivable $ 82,724 $ 2,584,879 $ 1,005,000 $ 343,886 $ 4,016,489 Repurchase agreement liabilities associated with these securities $ 79,850 $ 2,442,829 $ 965,603 $ 325,695 $ 3,813,977 Net weighted average borrowing rate 2.55% 2.37% 2.34% 2.29% 2.36% December 31, 2018 Fair market value of securities pledged, including accrued interest receivable $ - $ 1,720,804 $ 1,493,565 $ - $ 3,214,369 Repurchase agreement liabilities associated with these securities $ - $ 1,611,185 $ 1,413,867 $ - $ 3,025,052 Net weighted average borrowing rate - 2.72% 2.57% - 2.65% In addition, cash pledged to counterparties for repurchase agreements was approximately $27.1 million and $7.0 million as of September 30, 2019 and December 31, 2018, respectively. If , during the term of a repurchase agreement, a lender files for bankruptcy, the Company might experience difficulty recovering its pledged assets , which could result in an unsecured claim against the lender for the difference between the amount loaned to the Company plus interest due to the counterparty and the fair value of the collateral pledged to such lender , including the accrued interest recei vable and cash posted by the Company as collateral. At September 30, 2019 , the Company had an aggregate amount at risk (the difference between the amount loaned to the Company, including interest payable and securities posted by the counterparty (if any), and the fair value of securities and cash pledged (if any), including accrued interest on such securities) with all counterparties of approximately $217.7 million . The Company did not have an amount at risk with any individual counterparty greater than 10 % of the Company’s equity at September 30, 2019 and December 31, 2018

We minimize this risk by limiting our counterparties for instruments which are not centrally cleared on a registered exchange to major financial institutions with acceptable credit ratings and monitoring positions with individual counterparties. In addition, we may be required to pledge as sets as collateral for our derivatives, whose amounts vary over time based on the market value, notional amount and remaining term of the derivative contract. In the event of a default by a counterparty , we may not receive payments provided for under the t erms of our derivative agreements, and may have difficulty obtaining our assets pledged as collateral for our derivatives. The cash and cash equivalents pledged as collateral for our derivative instruments are included in restricted cash on our balance sheets." id="sjs-B4">NOTE 4 . DERIVATIVE FINANCIAL INSTRUMENTS In connection with its interest rate risk management strategy, the Company economically hedges a portion of the cost of its repurchase agreement funding by entering into derivatives and other hedging contracts. To date, the Company has entered into Eurodollar, Fed Funds and T-Note futures contracts, interest rate swaps, and interest rate swaptions, but may enter into other contracts in the future. The Company has not elected hedging treatment under GAAP, and as such all gains or losses (realized and unrealized) on these instruments are reflected in earnings for all periods presented. In addition, the Company utilizes TBA securities as a means of investing in and financing PT RMBS or as a means of reducing its ex posure to PT RMBS. The Company accounts for TBA securities as derivative instruments if either the TBA securities do not settle in the shortest period of time possible or if the Company cannot assert that it is probable at inception and throughout the term of the TBA securities that it will take physical delivery of the Agency RMBS for a long position, or make delivery of the Agency RMBS for a short position, upon settlement of the trade.

The Incentive Plan provides for the award of stock options, stock appreciation rights, stock award, performance units, other equity-based awards (and dividend equivalents with respect to awards of performance units and other equity-based awards) and incentive awards. The Incentive Plan is administered by the Compensation Committee of the Company’s Board of Directors except that the Company’s full Board of Directors will administer awards made to directors who are n ot employees of the Company or its affiliates. The Incentive Plan provides for awards of up to an aggregate of 10% of the issued and outstanding shares of our common stock (on a fully diluted basis) at the time of the awards, subject to a maximum aggregat e 4,000,000 shares of the Company’s common stock that may be issued under the Incentive Plan. Stock Awards The Company has previously issued, and may in the future issue additional, immediately vested common stock under the Incentive Plan to certain executive officers and employees of its Manager. The Company’s non-employee directors received grants of immediately vested common stock for their service to the Company during the first quarter of 2018.

FAIR VALUE

FAIR VALUE	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value	NOTE 12 . FAIR VALUE The framework for using fair value to measure assets and liabilities defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price). A fair value measure should reflect the assumptions that market participants would us e in pricing the asset or liability, including the assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of non-performance. Required disclosures include stratificat ion of balance sheet amounts measured at fair value based on inputs the Company use s to derive fair value measurements. These stratifications are:  Level 1 valuations, where the valuation is based on quoted market prices for identical assets or liabilitie s traded in active markets (which include exchanges and over-the-counter markets with sufficient volume),  Level 2 valuations, where the valuation is based on quoted market prices for similar instruments traded in active markets, quoted prices for identica l or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market, and  Level 3 valuations, where the valuation is generated from model-based techniques that use s ignificant assumptions not observable in the market, but observable based on Company-specific data. These unobservable assumptions reflect the Company’s own estimates for assumptions that market participants would use in pricing the asset or liability. Val uation techniques typically include option pricing models, discounted cash flow models and similar techniques, but may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability. The C ompany's RMBS, interest rate swaps, interest rate swaptions and TBA securities are valued using Level 2 valuations, and such valuations currently are determined by the Company based on independent pricing sources and/or third party broker quotes, when avai lable. Because the price estimates may vary, the Company must make certain judgments and assumptions about the appropriate price to use to calculate the fair values. The Company and the independent pricing sources use various valuation techniques to determ ine the price of the Company’s securities. These techniques include observing the most recent market for like or identical assets, spread pricing techniques (option adjusted spread, zero volatility spread, spread to the U.S. T reasury curve or spread to a b enchmark such as a TBA), and model driven approaches (the discounted cash flow method, Black Scholes and SABR models which rely upon observable market rates such as the term structure of interest rates and volatility). The appropriate spread pricing method used is based on market convention. The pricing source determines the spread of recently observed trade activity or observable markets for assets similar to those being priced. The spread is then adjusted based on variances in certain characteristics betw een the market observation and the asset being priced. Those characteristics include: type of asset, the expected life of the asset, the stability and predictability of the expected future cash flows of the asset, whether the coupon of the asset is fixed o r adjustable, the guarantor of the security if applicable, the coupon, the maturity, the issuer, size of the underlying loans, year in which the underlying loans were originated, loan to value ratio, state in which the underlying loans reside, credit score of the underlying borrowers and other variables if appropriate. The fair value of the security is determined by using the adjusted spread. RMBS (based on the fair value option), interest rate swaps, interest rate swaptions, TBA securities and futures contracts were recorded at fair value on a recurring basis during the nine and three months ended September 30, 2019 and 2018 . When determining fair v alue measurements, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset. When possible, the Company looks to active and observable mar kets to price identical assets. When identical assets are not traded in active markets, the Company looks to market observable data for similar assets. The following table presents financial assets (liabilities) measured at fair value on a recurring basis as of September 30, 2019 and December 31, 2018 .

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Use of Estimates The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q a nd Article 8 of Regulation S- X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair p resentat ion have been included. Operating results for the nine and three month period ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year end ing December 31, 2019 . The balance sheet at December 31, 2018 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the financial statements and footnotes thereto inclu ded in the Company’s A nnual R eport on Form 10-K for the year ended December 31, 2018 .
Use of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and l iabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The significant estimat es affecting the accompanying financial statements are the fair values of RMBS and derivatives .
Variable Interest Entity [Policy Text Block]	Variable Interest Entities (“VIEs”) We obtain interests in VIEs through our investments in mortgage-backed securities. Our interests in these VIEs are passive in nature and are not expected to result in us obtaining a controlling financial interest in these VIEs in the future. As a result, we do not consolidate these VIEs and we account for our interest in these VIEs as mortgage-backed securities. See Note 2 for additional information regarding our investments in mortgage-backed securities. Our maximum exposure to loss for these VIEs is t he carrying value of the mortgage-backed securities.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents include cash on deposit with financial institutions and highly liquid investments with original maturities of three months or less at the time of purchase . Restricted cash includes cash pledged as collateral for repurchase agreements and other borrowings, and interest rate swaps and other derivative instruments. The following table provides a reconciliation of cash, cash equiva lents, and restricted cash reported within the statement of financial position that sum to the total of the same such amounts shown in the statement of cash flows. (in thousands) September 30, 2019 December 31, 2018 Cash and cash equivalents $ 147,428 $ 108,282 Restricted cash 54,788 17,981 Total cash, cash equivalents and restricted cash $ 202,216 $ 126,263 The Company maintains cash balances at three banks and excess margin on account with two exchange clearing members. At times, balances may exceed federally insured limits. The Company has not experienced any losses related to these balances. The Federal De posit Insurance Corporation insures eligible accounts up to $250,000 per depositor at each financial institution. At September 30, 2019 , the Company’s cash deposits exceeded federally insured limits by approximately $118.8 million. Restricted cash balan ces are uninsured, but are held in separate customer accounts that are segregated from the general funds of the counterparty. The Company limits uninsured balances to only large, well-known banks and exchange clearing members and believes that it is not exposed to any significant credit risk on cash and cash equivalents or restricted cash balances.
Mortgage-Backed Securities	Mortgage-Backed Securities The Company invests primarily in mortgage pass-through (“PT”) residential mortgage backed certificates issued by Freddie Mac, Fann ie Mae or Ginnie Mae (“RMBS” ) , collateralized mortgage obligations (“CMOs”) , interest- only (“IO”) securities and inverse interest- only (“IIO”) securities representing interest in or obligations backed by pools of RMBS . We refer to IO and IIO securities as structured RMBS. T he Company has elected to account for its investment in RMBS under the fair value option. Electing the fair value option require s the Company to record changes in fair value in the statement of operati ons, which, in management’s view, more appropriately reflects the results of our operations for a particular reporting period and is consistent with the underlying economics and how the portfolio is managed. The Company records RMBS transactions on the tr ade date. Security purchases that have not settled as of the balance sheet date are included in the RMBS balance with an offsetting liability recorded, whereas securities sold that have not settled as of the balance sheet date are removed from the RMBS bal ance with an offsetting receivable recorded. Fair value is defined as the price that would be received to sell the asset or paid to transfer the liability in an orderly transaction between market participants at the measurement date. The fair value measurement assumes that the transaction to sell th e asset or transfer the liability either occurs in the principal market for the asset or liability, or in the absence of a principal market, occurs in the most advantageous market for the asset or liability. Estimated fair values for RMBS are based on inde pendent pricing sources and/or third party broker quotes, when available. Income on PT RMBS securities is based on the stated interest rate of the security. Premiums or discounts present at the date of purchase are not amortized. Premium lost and discoun t accretion resulting from monthly principal repayments are reflected in unrealized gains (losses) on RMBS in the statements of operations. For IO securities, the income is accrued based on the carrying value and the effective yield. The difference between income accrued and the interest received on the security is characterized as a return of investment and serves to reduce the asset’s carrying value. At each reporting date, the effective yield is adjusted prospectively for future reporting period s based o n the new estimate of prepayments and the contractual terms of the security. For IIO securities, effective yield and income recognition calculations also take into account the index value applicable to the security. Changes in fair value of RMBS during eac h reporting period are recorded in earnings and reported as unrealized gains or losses on mortgage-backed securities in the accompanying statements of operations.
Derivative Financial Instruments	Derivative Financial Instruments The Company uses derivative instruments to manage interest rate risk, facilitate asset/liability strategies and manage other exposures, and it may continue to do so in the future. The principal instruments that the Company has used to date are Treasury Note (“T-Note”) , Fed Funds and Eurodollar futures contracts, interest rate swaps, options to enter in interest rate swaps (“interest rate swaptions”) and “to-be-announced” (“TBA”) securities transactions, but the Company may enter into other derivatives in the future. The Company accounts for TBA securities as derivative instruments if either the TBA securities do not settle in the shortest period of time possible or if the Company cannot assert that it is probable at inception of the TBA transaction, or throughout its term, that it will take physical delivery of the Agency RMBS for a long position, or make delivery of the Agency RMBS for a short position, upon settlement of the trade. Gains and losses associated with TBA securities transactions are reported in gain (lo ss) on derivative instruments in the accompanying statements of operations. Derivative instruments are carried at fair value, and changes in fair value are recorded in earnings for each period. The Company’s derivative financial instruments are not design ated as hedge accounting relationships, but rather are used as economic hedges of its portfolio assets and liabilities. Holding d erivatives creates exposure to credit risk related to the potential for failure on the part of counterparties and exchanges to honor their commitments. In addition, the Company may be required to post collateral based on any decli nes in the market value o f the d erivatives. In the event of default by a counterparty, the Company may have difficulty recovering its collateral and may not receive payments provided for under the terms of the agreement . To mitigate this risk, the Company uses only well-establis hed comme rcial banks and exchanges as counterparties.
Financial Instruments	Financial Instruments The fair value of financial instruments for which it is practicable to estimate that value is disclosed , either in the body of the financial statements or in the accompanying notes. RMBS, Eurodollar and T-Note futures contracts, interest rate swaps, interest rate swaptions and TBA securities are accounted for at fair value in the balance sheets. The methods and assumptions used to estimate fair value for these instruments are p resented in Note 12 of the financial statements. The estimated fair value of cash and cash equivalents, restricted cash, accrued interest receivable, receivable for securities sold, other assets, due to affiliates, repurchase agreements , payable for unsettled securities purchased, accrued interest payable and other liabilities generally approximates their carrying values as of September 30, 2019 and December 31, 2018 due to the short-term nature of these financial instruments.
Repurchase Agreements	Repurchase Agreements The Company finances the acquisition of the majority of its RMBS through the use of repurchase agreements under master repurchase agreements. Repurchase agreements are accounted for as collateralized financing transactions, which are carried at their contract ual amounts, including accrued interest, as specified in the respective agreements.
Management Fees	Manager Compensation The Company is externally managed by Bimini Advisors, LLC ( th e “Manager” or “Bimini Advisors”) , a Maryland limited liability company and wh olly-owned subsidiary of Bimini . The Company’s management agreement with the Manager provides for payment to the Manager of a management fee and reimbursement of certain operating expenses, which are accrued and expensed during the period for which they ar e earned or incurred. Refer to Note 13 for the terms of the management agreement.
Earnings Per Share	Earnings Per Share Basic earnings per share (“EPS”) is calculated as net income or loss attributable to common stockholders divided by the weighted average number of sha res of common stock outstanding or subscribed during the period. Diluted EPS is calculated using the treasury stock or two-class method, as applicable, for common stock equivalents, if any. However, the common stock equivalents are not included in computin g diluted EPS if the result is anti-dilutive.
Income Taxes	Income Taxes Orchid has qualified and elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code ”). REITs are generally not subject to federal income tax on their REIT taxable income provided that they distribute to their stockholders at least 90% of their REIT taxable income on an annual basis. In addition, a REIT must meet other provisions of the Code to retain its tax status. Orchid assesses the likelihood, based on their technical merit, that uncertain tax positions will be sustained upon examination based on the facts, circumstances and information available at the end of each period. All of Orchid’s tax positions are catego rized as highly certain. There is no accrual for any tax, interest or penalties related to Orchid’s tax position assessment. The measurement of uncertain tax positions is adjusted when new information is available, or when an event occurs that requires a change.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss model). ASU 2016-13 is effective for fiscal years, and for interim periods within those years, beginning after December 15, 2019. Early application is permitted for fiscal periods beginnin g after December 15, 2018. The Company does not expect that the adoption of this ASU will have a significant effect on its financial statements.
