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 wholl y 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 stock 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 March 31, 2019 , the Company issued a total of 9,013,946 shares under the August 2017 Equity Distribution Agreement for aggregate gross proceeds of approximately $84.6 million, and net proceeds of approximately $83.3 million, net o f commissions and fees . Subsequent t o March 31, 2019 , the Company issued an additional 1,432,466 shares under the August 2017 Equity Distribution Agreement for aggregate gross proceeds of approximately $ 9.6 million, and net proceeds of approximately $9 .5 million, net of commissions and fees. 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 resentation have been included. Operating results for the three month period ended March 31, 2019 are not n ecessarily 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 a nd footnotes required by GAAP for complete financial statements. For further information, refer to the financial statements and footnotes thereto included in the Company’s A nnual R eport on Form 10-K for the year ended December 31, 2018 . The preparatio n of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements a nd the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The significant estimates affecting the accompanying financial statements are the fair values of RMBS and derivatives . Statement of Comprehensive Income (Loss) In accordance with the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC”) Topic 220, Comprehensive Income , a statement of comprehensive income (loss) has not been included a s the Company has no items of other comprehensive income (loss) . Comprehensive income (loss) is the same as net income (loss) for the periods presented. 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) March 31, 2019 December 31, 2018 Cash and cash equivalents $ 125,933 $ 108,282 Restricted cash 16,998 17,981 Total cash, cash equivalents and restricted cash $ 142,931 $ 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 March 31, 2019 , the Company’s cash deposits exceeded federally insured limits by approximately $123.5 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 stateme nt of operations, 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 transacti ons on the trade 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 balance with an offsetting receivable recorded. The fair value of the Company’s investments in RMBS is governed by FASB ASC 820, Fair Value Measurement . The definition of fair value in FASB ASC 820 focuses on 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 the 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 va lues for RMBS are based on independent 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 amor tized. Premium lost and discount 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 prospe ctively for future reporting period s based on 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 securi ty. Changes in fair value of RMBS during each 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 ar e Treasury Note (“T-Note”) 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 posi tion, upon settlement of the trade. Gains and losses associated with TBA securities transactions are reported in gain (loss) on derivative instruments in the accompanying statements of operations. The Company has elected not to treat any of its derivative financial instruments as hedges in order to align the accounting treatment of its derivative instruments with the treatment of its portfolio assets under the fair value option election . FASB ASC Topic 815, Derivatives and Hedgin g , requires that all derivative instruments be carried at fair value. Changes in fair value are recorded in earnings for each period. Holding d erivatives creates exposure to credit risk related to the potential for failure on the part of counterparties a nd exchanges to honor their commitments. In addition, the Company may be required to post collateral based on any decli nes in the market value of the d erivatives. In the event of default by a counterparty, the Company may have difficulty recovering its c ollateral and may not receive payments provided for under the terms of the agreement . To mitigate this risk, the Company uses only well-established comme rcial banks and exchanges as counterparties. Financial Instruments FASB ASC 825, Financial Instruments , requires disclosure of the fair value of financial instruments for which it is practicable to estimate that value, either in the body of the financial statements or in the accompanying notes. RMBS, Eurodollar and T-Note futures contracts, inte rest 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 presented in Note 12 of the fin ancial 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, acc rued interest payable and other liabilities generally approximates their carrying values as of March 31, 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. Pursuant to ASC Topic 860, Transfers and Servicing , the Company accounts for repurchase transactions as collateral ized financing transactions, which are carried at their contractual 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, whi ch are accrued and expensed during the period for which they are earned or incurred. Refer to Note 13 for the terms of the management agreement. Earnings Per Share The Company follows the provisions of FASB ASC 260, 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 shares of common stock outstanding or subscribed during the period. Diluted EPS is calculated using the treasury st ock or two-class method, as applicable, for common stock equivalents, if any. However, the common stock equivalents are not included in computing 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 measures , recognizes and presents its uncertain tax positions in accordance with FASB ASC 740, Income Taxes . Under that guidance, Orchid assesses the likelihood, based on their technical merit, that tax positions will be sustained upon examination based on the fa cts, circumstances and information available at the end of each period. All of Orchid’s tax positions are categorized 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 November 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-18, Statement of Cash Flows – (Topic 230): Restricted Cash. ASU 2016-18 requires that restricted cash and restricted cash equivalents be included as components of total cash and cash equivalents as presented on the statement of cash flows. ASU 2016-18 is effective for fiscal years, and for interim periods within those years, beginning after December 15, 2017. Early application is permitted. The Company early adopted the ASU begi nning with the first quarter of 2017. 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 measure d 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 a fter December 15, 2019. Early application is permitted for fiscal periods beginning 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 calls." Similarly, if the fair value of the pledged securities increases, lenders may release collateral back to the Company. As of March 31, 2019 , the Company had met all margin call requirements. As of March 31, 2019 , the Company had outstanding repurchase obligations of approximately $2,866.7 million with a net weighted average borrowing rate of 2.70% . These agreements were collateralized by RMBS with a fair value, including accrue d interest and securities pledged related to securities sold but not yet settled, of approximately $3,041.4 million, and cash pledged to the counterparties of approximately $6.8 million. As of December 31, 2018 , the Company had out standing repurchase obligations of approximately $3,025.1 million with a net weighted average borrowing rate of 2.65% . These agreements were collateralized by RMBS with a fair value, including accrued interest, of approximately $3,214.4 million , and cash pledged to the counterparties of approximately $7.0 million.

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 and T-Note futures contracts, interes t 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 exposure to PT RMBS. The Company accounts for TBA securities as derivative instruments if ei ther 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 p osition, or make delivery of the Agency RMBS for a short position, upon settlement of the trade.

FAIR VALUE

FAIR VALUE	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value	NOTE 12 . FAIR VALUE Authoritative accounting literature establishes a framework for using fair value to measure assets and liabilities and defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) as opposed to the price that would be paid to acquire the asset or received to assume the liability (an entry price). A fair value measure should reflect the assumptions that market participants would use in pricing the asset or l iability, 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 stratification of balance sheet amount s measured at fair value based on inputs the Company uses to derive fair value measurements. These stratifications are: Level 1 valuations, where the valuation is based on quoted market prices for identical assets or liabilities 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 identical 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 significant 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. Valuation 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 Company's RMBS, interest rat e 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 available. Because the price es timates 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 determine the price of the Compan y’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 benchmark such as a TBA), an d 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 marke t 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 between the market observat ion 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 or adjustable, the guara ntor 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 borr owers 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 three months ended March 31, 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 March 31, 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 resentation have been included. Operating results for the three month period ended March 31, 2019 are not n ecessarily 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 a nd footnotes required by GAAP for complete financial statements. For further information, refer to the financial statements and footnotes thereto included in the Company’s A nnual R eport on Form 10-K for the year ended December 31, 2018 .
Use of Estimates	The preparatio n of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements a nd the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The significant estimates affecting the accompanying financial statements are the fair values of RMBS and derivatives .
Statement of Comprehensive Income	Statement of Comprehensive Income (Loss) In accordance with the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC”) Topic 220, Comprehensive Income , a statement of comprehensive income (loss) has not been included a s the Company has no items of other comprehensive income (loss) . Comprehensive income (loss) is the same as net income (loss) for the periods presented.
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) March 31, 2019 December 31, 2018 Cash and cash equivalents $ 125,933 $ 108,282 Restricted cash 16,998 17,981 Total cash, cash equivalents and restricted cash $ 142,931 $ 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 March 31, 2019 , the Company’s cash deposits exceeded federally insured limits by approximately $123.5 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 stateme nt of operations, 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 transacti ons on the trade 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 balance with an offsetting receivable recorded. The fair value of the Company’s investments in RMBS is governed by FASB ASC 820, Fair Value Measurement . The definition of fair value in FASB ASC 820 focuses on 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 the 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 va lues for RMBS are based on independent 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 amor tized. Premium lost and discount 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 prospe ctively for future reporting period s based on 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 securi ty. Changes in fair value of RMBS during each 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 ar e Treasury Note (“T-Note”) 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 posi tion, upon settlement of the trade. Gains and losses associated with TBA securities transactions are reported in gain (loss) on derivative instruments in the accompanying statements of operations. The Company has elected not to treat any of its derivative financial instruments as hedges in order to align the accounting treatment of its derivative instruments with the treatment of its portfolio assets under the fair value option election . FASB ASC Topic 815, Derivatives and Hedgin g , requires that all derivative instruments be carried at fair value. Changes in fair value are recorded in earnings for each period. Holding d erivatives creates exposure to credit risk related to the potential for failure on the part of counterparties a nd exchanges to honor their commitments. In addition, the Company may be required to post collateral based on any decli nes in the market value of the d erivatives. In the event of default by a counterparty, the Company may have difficulty recovering its c ollateral and may not receive payments provided for under the terms of the agreement . To mitigate this risk, the Company uses only well-established comme rcial banks and exchanges as counterparties.
Financial Instruments	Financial Instruments FASB ASC 825, Financial Instruments , requires disclosure of the fair value of financial instruments for which it is practicable to estimate that value, either in the body of the financial statements or in the accompanying notes. RMBS, Eurodollar and T-Note futures contracts, inte rest 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 presented in Note 12 of the fin ancial 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, acc rued interest payable and other liabilities generally approximates their carrying values as of March 31, 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. Pursuant to ASC Topic 860, Transfers and Servicing , the Company accounts for repurchase transactions as collateral ized financing transactions, which are carried at their contractual 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, whi ch are accrued and expensed during the period for which they are earned or incurred. Refer to Note 13 for the terms of the management agreement.
Earnings Per Share	Earnings Per Share The Company follows the provisions of FASB ASC 260, 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 shares of common stock outstanding or subscribed during the period. Diluted EPS is calculated using the treasury st ock or two-class method, as applicable, for common stock equivalents, if any. However, the common stock equivalents are not included in computing 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 measures , recognizes and presents its uncertain tax positions in accordance with FASB ASC 740, Income Taxes . Under that guidance, Orchid assesses the likelihood, based on their technical merit, that tax positions will be sustained upon examination based on the fa cts, circumstances and information available at the end of each period. All of Orchid’s tax positions are categorized 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 November 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-18, Statement of Cash Flows – (Topic 230): Restricted Cash. ASU 2016-18 requires that restricted cash and restricted cash equivalents be included as components of total cash and cash equivalents as presented on the statement of cash flows. ASU 2016-18 is effective for fiscal years, and for interim periods within those years, beginning after December 15, 2017. Early application is permitted. The Company early adopted the ASU begi nning with the first quarter of 2017. 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 measure d 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 a fter December 15, 2019. Early application is permitted for fiscal periods beginning after December 15, 2018. The Company does not expect that the adoption of this ASU will have a significant effect on its financial statements.
