Organization, Consolidation and Presentation of Financial Statements [Abstract]
NATURE OF BUSINESS AND BASIS OF PRESENTATION	NATURE OF BUSINESS AND BASIS OF PRESENTATION Nature of Business Rimini Street, Inc. (“the Company”) is a global provider of enterprise software support services. The Company’s subscription-based software support products and services offer enterprise software licensees a choice of solutions that replace or supplement the support products and services offered by enterprise software vendors. Basis of Presentation and Consolidation The unaudited condensed consolidated financial statements, which include the accounts of the Company and its wholly owned subsidiaries, are prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”). All significant intercompany balances and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, certain information and footnote disclosures required by GAAP for complete financial statements have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the unaudited condensed consolidated financial statements have been included. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements for the year ended December 31, 2018 , included in the Company’s 2018 Annual Report on Form 10-K as filed with the SEC on March 14, 2019 (the “ 2018 Form 10-K”). The accompanying condensed consolidated balance sheet and related disclosures as of December 31, 2018 have been derived from the Company’s audited financial statements. The Company’s financial condition as of June 30, 2019 , and operating results for both the three and six months ended June 30, 2019 are not necessarily indicative of the financial condition and results of operations that may be expected for any future interim period or for the year ending December 31, 2019 .

Accounting Policies [Abstract]
LIQUIDITY AND SIGNIFICANT ACCOUNTING POLICIES	LIQUIDITY AND SIGNIFICANT ACCOUNTING POLICIES Liquidity As of June 30, 2019 , the Company’s current liabilities exceeded its current assets by $104.8 million , and the Company earned net income of $4.1 million for the three months ended June 30, 2019 . As of June 30, 2019 , the Company had available cash, cash equivalents and restricted cash of $50.3 million . As of June 30, 2019, the Company's current liabilities included $190.9 million of deferred revenue whereby the historical costs of fulfilling the Company's commitments to provide services to its customers was approximately 37% of the related deferred revenue for the three months ended June 30, 2019. As discussed in Note 5, the Company completed a third private placement on June 20, 2019, which provided additional net proceeds of $3.0 million from the sale of 3,500 shares of 13.00% Series A Redeemable Convertible Preferred Stock, par value $0.0001 per share (the “ Series A Preferred Stock ” ) and 72,414 shares of Common Stock. On March 7, 2019, the Company had completed a second private placement, which provided additional net cash proceeds of $5.0 million from the sale of 6,500 shares of the Series A Preferred Stock and 134,483 shares of Common Stock. In 2018, the Company had previously refinanced and repaid its Credit Facility (defined below) on July 19, 2018 through aggregate cash payments of $132.8 million that resulted in the termination of the Credit Facility. These cash payments were funded from the Initial Private Placement (defined below) discussed in Note 5 that resulted in cash proceeds of $133.0 million from the sale of 140,000 shares of Series A Preferred Stock and approximately 2.9 million shares of Common Stock. These refinancing arrangements are expected to improve the Company’s liquidity and capital resources whereby cash dividends are payable at 10.0% per annum that will result in quarterly cash dividends ranging from $3.7 million to $4.3 million over the initial 5 -year period beginning on the issuance date assuming all shares of Series A Preferred Stock remain outstanding, and thereafter, if not previously redeemed or converted, cash dividends will be payable at 13.0% per annum. Additionally, as discussed in Note 4, the Company repaid the $1.2 million note payable to GPIC, Ltd. ( “ GP Sponsor ” ) during the second quarter of 2019, and is obligated to make operating and capital lease payments that are due within the next 12 months in the aggregate amount of $6.1 million . The Company believes that current cash, cash equivalents, restricted cash, and future cash flow from operating activities will be sufficient to meet the Company’s anticipated cash needs, including cash dividend requirements, working capital needs, capital expenditures and contractual obligations for at least 12 months from the issuance date of these financial statements. Use of Estimates The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in its consolidated financial statements and accompanying notes. The Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes are reasonable under the circumstances, to determine the carrying values of assets and liabilities that are not readily apparent from other sources. The Company’s significant accounting estimates include, but are not necessarily limited to, accounts receivable, valuation assumptions for stock options, deferred income taxes and the related valuation allowances, and the evaluation and measurement of contingencies. To the extent there are material differences between the Company’s estimates and the actual results, the Company’s future consolidated results of operation may be affected. Recent Accounting Pronouncements Recently Adopted Standards. The following accounting standards were adopted during the first quarter of fiscal year 2019 : In May 2017, the FASB issued ASU No. 2017-9, Compensation-Stock Compensation: Scope of Modification Accounting , which provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This standard does not change the accounting for modifications of share-based payment awards but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. This standard did not have a material impact for the Company during the three and six months ended June 30, 2019. In August 2018, the SEC adopted a final rule that extends the current annual requirement to disclose changes in stockholders’ equity to interim periods and also requires interim disclosure of dividends per share for each class of shares (including the Company’s Series A Preferred Stock). These disclosure provisions became effective beginning in the first quarter of 2019, whereby the Company is required to disclose changes in stockholders’ deficit for the current and comparative fiscal quarters as well as the current and comparative year-to-date periods presented in interim condensed consolidated financial statements. The Company has provided an unaudited condensed consolidated statement of stockholders' deficit for the three and six months ended June 30, 2019 and 2018. The following accounting standards are not yet effective; Management has not completed its evaluation to determine the impact that adoption of these standards will have on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which supersedes nearly all existing revenue recognition standards under U.S. GAAP. The new standard provides a five-step process for recognizing revenue that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard also requires expanded qualitative and quantitative disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The new standard allows for two transition methods: (i) a full retrospective method applied to each prior reporting period presented, or (ii) a modified retrospective method applied with the cumulative effect of adoption recognized on adoption date. The Company currently intends to adopt this standard using the full retrospective method. Due to the Company’s emerging growth company status and certain elections made, the new standard is effective for the Company in fiscal year 2019. As an emerging growth company for interim reporting purposes, we can elect to initially apply the standard either in the year of adoption or in the subsequent year. The Company has elected to adopt the standard for interim reporting purposes beginning in the first quarter of fiscal 2020. As a result of this election, fiscal year 2019 interim periods will continue to be reported under legacy GAAP while full year 2019 results will be reported under the new standard. We have made significant progress in our analysis of how the standard will impact our revenue, but we have not completed our evaluation and therefore the full impact upon adoption of this standard is not known and cannot be reasonably estimated. Based on our preliminary evaluation to date, we believe that the primary change will be the accelerated timing of revenue recognition for certain contracts due to the removal of the current limitation associated with revenue contingent upon the future delivery of support services. In addition, we expect to capitalize costs incurred to obtain new client contracts, which is primarily comprised of sales commissions. Such costs, which are expensed as incurred under the current standard, will be capitalized and amortized over their estimated useful lives under the new standard. We will complete our evaluation during fiscal year 2019. In February 2016, the FASB issued ASU No. 2016-02, Leases , which requires organizations that lease assets (“lessees”) to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases with lease terms of more than 12 months. Under the new standard, both finance and operating leases will be required to be recognized on the balance sheet. Additional quantitative and qualitative disclosures, including significant judgments made by management, will also be required. The standard will be effective for the Company beginning in the first quarter of fiscal 2020. Early adoption is permitted, and the new standard was initially required to be adopted retrospectively to each prior reporting period presented upon initial adoption. However, in July 2018 the FASB issued ASU No. 2018-11 Targeted Improvements , which provides lessees the option to apply the new leasing standard to all open leases as of the adoption date by recognizing a cumulative-effect adjustment to accumulated deficit in the period of adoption without restating prior periods. The Company is still evaluating which transition approach will be implemented upon its adoption of ASU No. 2016-02.

As of June 30, 2019 and December 31, 2018 , the net carrying value and balance sheet classification of debt is summarized as follows (in thousands): 2019 2018 Note payable to GP Sponsor, net of DDIC $ — $ 2,372 Less current maturities — 2,372 Long-term debt, net of current maturities $ — $ — For purposes of classifying current maturities of long-term debt in the Company’s balance sheets, none of the discount is attributed to the current portion until the maturity date is less than one year from the balance sheet date. As discussed below, the Company has repaid the related party note payable to GP Sponsor during the second quarter of 2019. Also discussed below, the Company repaid in full and terminated its former Credit Facility on July 19, 2018 . Related Party Note Payable Upon consummation of the merger with GP Investments Acquisition Corp. ("GPIA") in May 2017, an outstanding note payable to GP Sponsor with an initial face amount of approximately $3.0 million was assumed by the Company. This note was originally non-interest bearing and was not due and payable until the outstanding principal balance under the former Credit Facility was less than $95.0 million . At the inception of this note, the maturity date was expected to occur in June 2020 based on the scheduled principal payments under the Credit Facility. Interest was initially imputed under this note payable at the rate of 15.0% per annum. The net carrying value of this note payable was $2.1 million as of December 31, 2017, and the Company recognized accretion expense of $0.2 million and $0.4 million for the three months and six months ended June 30, 2018, respectively. This note payable was amended twice in 2018 which resulted in further changes to the effective interest rate. The second amendment to the loan agreement was effective on December 21, 2018, and provided for an extension of the maturity date from January 4, 2019 to June 28, 2019. In addition, the parties agreed that the note payable would retroactively bear interest at 13.0% per annum from July 19, 2018 through the maturity date. Total retroactive interest amounted to $0.2 million which is accounted for as DDIC that was being accreted through the maturity date. In addition, the second amendment provided for monthly principal payments starting in December 2018 of approximately $0.4 million plus accrued interest. In December 2018, the Company made a payment of $0.6 million , primarily consisting of payment of retroactive interest of $0.2 million and the first monthly principal payment of $0.4 million . The Company made principal and interest payments totaling $1.3 million and $2.7 million during the three months and six months ended June 30, 2019, respectively. The effective interest rate for accretion of DDIC was 26.4% for the period from December 21, 2018 through June 28, 2019. The note was paid off on June 28, 2019. Former Credit Facility Overview. In June 2016, the Company entered into a multi-draw term loan Financing Agreement (the “Credit Facility”) with a syndicate of lenders (the “Lenders”). The Credit Facility would have matured in June 2020 but was repaid and terminated in July 2018 as discussed below. The Credit Facility provided for an aggregate commitment of up to $125.0 million which consisted of an initial term loan for $30.0 million , a “delayed draw A Term Loan” for $65.0 million , and a “delayed draw B Term Loan” for $30.0 million . An origination fee equal to 5.0% of the $125.0 million commitment was paid in cash to the Lenders from the proceeds of the initial term loan. The Credit Facility provided for an Original Issue Discount (“OID”) of 2.0% of the initial face amount of borrowings. Origination fees and OID were accounted for as DDIC. Borrowings under the Credit Facility were collateralized by substantially all assets of the Company, including certain cash depository accounts that were subject to control agreements with the Lenders. Interest and Fees. The outstanding principal balance under the former Credit Facility provided for monthly interest payments at 15.0% per annum, consisting of 12.0% per annum that was payable in cash and 3.0% per annum that was payable through the issuance of additional borrowings beginning on the interest payment due date (referred to as paid-in-kind, or “PIK” interest). In addition, a make-whole applicable premium payment of approximately 15.0% per annum through June 2019 was required for certain principal prepayments as defined in the Credit Facility. The Credit Facility provided for collateral monitoring fees at the rate of 2.5% of the outstanding principal balance during 2018 until the Credit Facility was terminated. The Credit Facility also required unused line fees of 5.0% per annum on the $17.5 million undrawn portion of the Credit Facility during 2018 until the termination date. All unused line fees and collateral monitoring fees were payable monthly in arrears and were recorded as a component of other debt financing expenses in the period incurred. Accretion and Amortization. DDIC that relates to the entire Credit Facility was allocated pro rata between the funded and unfunded portions of the Credit Facility based on the relative amounts that were cumulatively borrowed versus the undrawn portion of the $125.0 million commitment. DDIC related to funded debt was accreted to interest expense using the effective interest method based on the aggregate principal obligations to the Lenders and consulting and Trigger Event exit fee obligations to one of the lenders that served as the origination agent (the “Origination Agent”). DDIC associated with unfunded debt was amortized using the straight-line method from the date incurred through the maturity date of the Credit Facility, which was included in other debt financing expenses in the accompanying unaudited condensed consolidated statements of operations and comprehensive loss. Termination of the Credit Facility. In connection with the closing on July 19, 2018 of the Initial Private Placement discussed in Note 5, the Company used substantially all of the $133.0 million of gross proceeds from the Initial Private Placement (together with cash-on-hand) to repay all outstanding indebtedness and fees under the Credit Facility, and the Credit Facility was terminated. The aggregate cash payments to terminate the Credit Facility amounted to $132.8 million and consisted of the following (in thousands): Contractual principal and exit fees: Principal balance $ 102,576 Mandatory trigger event exit fees 13,624 Mandatory consulting 2,000 Subtotal 118,200 Make-whole applicable premium 7,307 Amendment fees and related liabilities 6,250 Accrued interest and fees payable 1,073 Total cash termination payments $ 132,830 Interest Expense The components of interest expense are presented below (in thousands): Three Months Ended Six Months Ended 2019 2018 2019 2018 Credit Facility: Interest expense at 12.0% $ — $ 3,156 $ — $ 6,882 PIK interest at 3.0% — 793 — 1,724 Accretion expense for funded debt — 5,181 — 10,599 Make-whole applicable premium — — — 3,103 Accretion expense for GP Sponsor note payable 57 160 185 367 Interest on other borrowings 59 33 163 57 Total interest expense $ 116 $ 9,323 $ 348 $ 22,732 Other Debt Financing Expenses The components of other debt financing expenses are presented below (in thousands): Three Months Ended Six Months Ended 2019 2018 2019 2018 Write-off of DDIC related to Credit Facility $ — $ — $ — $ 7,169 Collateral monitoring fees — 659 — 1,435 Amortization of DDIC related to unfunded debt — 343 — 686 Unused line fees — 223 — 439 Amortization of prepaid agent fees and other — 114 — 227 Total other debt financing fees $ — $ 1,339 $ — $ 9,956

The aggregate cash proceeds from the Initial Private Placement were $133.0 million in cash (after taking into account a discount of $7.0 million , but before the incremental and direct transaction costs associated with the Initial Private Placement of $4.6 million ). The Company used the net proceeds from the 2018 SPA to repay all outstanding indebtedness and various fees and expenses under the former Credit Facility as discussed in Note 4, and to pay certain fees and expenses of the Purchasers and the Company in connection with the 2018 SPA. Agreements Related to Private Placement Transactions In connection with the completion of the Initial Private Placement, the Company, among other customary closing actions, (i) filed a Certificate of Designations with the State of Delaware setting forth the rights, preferences, privileges, qualifications, restrictions and limitations on the Series A Preferred Stock (the “CoD”), (ii) entered into a Registration Rights Agreement with the Purchasers setting forth certain registration rights of the Purchasers (the “Registration Rights Agreement”), (iii) delivered a Convertible Note to each Purchaser, and (iv) entered into a Security Agreement (the “Security Agreement”) in respect of the Company’s assets collateralizing the amounts that may become payable pursuant to the Promissory Notes if certain redemption provisions of the Series A Preferred Stock are triggered in the future. In connection with both the March 2019 and June 2019 Private Placements, the Company entered into a securities purchase agreement, a Registration Rights Agreement, a First (March 2019) and Second (June 2019) Amendment to the Security Agreement, as well as issued Convertible Notes to each investor, in each case substantially in the same form as entered into by the Company in the Initial Private Placement. Certificate of Designations of the Series A Preferred Stock and Dividends The CoD authorizes the issuance of up to 180,000 shares of Series A Preferred Stock. The holders of Series A Preferred Stock are entitled to (i) a cash dividend of 10.0% per annum (the “Cash Dividend”), payable quarterly in arrears, and (ii) a payment-in-kind dividend of 3.0% per annum (the “PIK Dividend” and together with the Cash Dividend, the “Dividends”). The PIK dividend is accrued quarterly in arrears for the first five years following the Closing and thereafter all Dividends accruing on such Series A Preferred Stock will be payable in cash at a rate of 13.0% per annum. The Series A Preferred Stock is classified as mezzanine equity in the Company’s consolidated balance sheet as of June 30, 2019 and December 31, 2018 since the holders have redemption rights beginning on July 19, 2023 (and earlier under certain circumstances). As required under the CoD, the Cash Dividends and PIK Dividends for the period in which the Series A Preferred Stock was outstanding during the second quarter of 2019 were settled on July 1, 2019 to holders of record on June 16, 2019. Accordingly, the Company accrued a current liability for accrued Cash Dividends through June 30, 2019 for $3.8 million . A long-term liability was recorded for $1.1 million of PIK Dividends that accrued through June 30, 2019, and that were settled through the issuance of 1,115 shares of Series A Preferred Stock on July 1, 2019. Presented below is a summary of total and per share dividends declared through June 30, 2019 (dollars in thousands, except per share amounts): Dividends Payable in: Total Dividends Cash PIK Dividends Per Share Dividends payable as of December 31, 2018 $ 3,521 $ 1,056 $ 4,577 $ 32.50 Cash Dividends 10% per annum 3,593 — 3,593 25.00 PIK Dividends 3% per annum — 1,065 1,065 7.41 Fractional PIK shares settled for cash 13 — 13 0.09 Less dividends settled January 2, 2019 (3,566 ) (1,062 ) (4,628 ) (32.62 ) Dividends payable as of March 31, 2019 3,561 1,059 4,620 31.13 Cash Dividends 10% per annum 3,747 — 3,747 25.00 PIK Dividends 3% per annum — 1,115 1,115 7.44 Fractional PIK shares settled for cash 9 — 9 0.06 Less dividends settled April 1, 2019 (3,561 ) (1,059 ) (4,620 ) (30.82 ) Dividends payable as of June 30, 2019 $ 3,756 $ 1,115 $ 4,871 $ 31.84 The liquidation value of the Series A Preferred Stock is convertible into shares of Common Stock at an initial conversion rate of $10.00 per share for a total of 15.3 million shares of Common Stock based on 152,967 shares of Series A Preferred Stock outstanding as of June 30, 2019. Each share of Series A Preferred Stock is convertible at the holder’s option into one share of Common Stock at a conversion price equal to the quotient of (i) the Liquidation Preference (as defined below), and (ii) $10.00 (subject to appropriate adjustment in the event of a stock split, stock dividend, combination or other similar recapitalization) (the “Per Share Amount”). The Company has the right to convert outstanding shares of Series A Preferred Stock into Common Stock for the Per Share Amount after July 19, 2021, if the Company’s volume weighted average stock price for at least 30 trading days of the 45 consecutive trading days immediately preceding such conversion is greater than $11.50 per share. The Company can exercise this right to convert twice per calendar year for a maximum number of shares of Common Stock that has publicly traded over the 60 consecutive trading days prior to the conversion date (less any shares of Common Stock that have been issued pursuant to any such conversion during such 60 -day period). The Series A Preferred Stock will become mandatorily redeemable, upon the election by the holders of a majority of the then outstanding shares, on or after July 19, 2023. Any and all of the then outstanding liquidation value of the Series A Preferred Stock plus any capitalized PIK Dividends and any unpaid accrued Cash Dividends not previously included in the Liquidation Preference (the “Redemption Amount”) is required to be repaid in full in cash on such redemption date or satisfied in the form of obligations under the Convertible Notes. Additionally, in certain circumstances the Company may require the holders of shares of the Series A Preferred Stock to convert into shares of Common Stock in lieu of cash payable upon redemption. The Series A Preferred Stock will also become mandatorily redeemable at any time upon the reasonable determination of the holders of a majority of the Series A Preferred Stock then outstanding of the occurrence of a Material Adverse Effect or the occurrence of a Material Litigation Effect (as such terms are defined in the CoD), with the Redemption Amounts payable automatically becoming payment obligations pursuant to the Convertible Notes with a concurrent cancellation of the shares of the Series A Preferred Stock, unless under certain circumstances, the Company redeems the Series A Preferred Stock for cash at such time. Prior to July 19, 2021, the Company will have the right to redeem up to $80.0 million of shares of the Series A Preferred Stock for cash amounts equal to the Redemption Amount which would include a make-whole premium that provides the holders thereof with full yield maintenance as if the Series A Preferred Stock was held until July 19, 2021, provided that such redemptions are subject to certain conditions and limitations. After July 19, 2021, the Company will have the right to redeem shares of Series A Preferred Stock for a cash per share amount equal to the Redemption Amount. The holders of Series A Preferred Stock may exercise their conversion rights prior to any optional redemption. In the event of a liquidation, dissolution or winding up of the Company, the Series A Preferred Stock is entitled to a liquidation preference in the amount of the greater of (i) $1,000 plus accrued but unpaid Dividends (the “Liquidation Preference”), and (ii) the per share amount of all cash, securities and other property to be distributed in respect of the Common Stock such holder would have been entitled to receive for its Series A Preferred Stock on an as-converted basis. In the event of a liquidation, dissolution or winding up of the Company prior to July 19, 2021, the holders are entitled to a make-whole premium that provides the holders thereof with full yield maintenance as if the shares of Series A Preferred Stock were held until July 19, 2021. Until approximately 95% of the Series A Preferred Stock or Convertible Notes are no longer outstanding, the Company is restricted from incurring Indebtedness (as defined in the June 2019 SPA, March 2019 SPA and 2018 SPA), subject to certain exceptions. Registration Rights Agreement The original Registration Rights Agreement required the Company to register the resale of the shares of Common Stock and Series A Preferred Stock issued pursuant to the 2018 SPA. The Company satisfied such registration requirements in November 2018. The Registration Rights Agreements, entered into in connection with both the March 2019 and June 2019 Private Placements, require the Company to register the resale of the shares of Common Stock and Series A Preferred Stock pursuant to the March 2019 SPA and the June 2019 SPA within 120 days of the respective March 7, 2019 and June 20, 2019 closing dates. The Company satisfied such registration requirements in July 2019. Each such Registration Rights Agreement also includes customary “piggyback” registration rights, suspension rights, indemnification, contribution, and assignment provisions.

The 2007 Plan and the 2013 Plan are collectively referred to as the “Stock Plans”. For additional information about the Stock Plans, please refer to Note 8 to the Company’s consolidated financial statements for the year ended December 31, 2018 , included in the 2018 Form 10-K. The information presented below provides an update for activity under the Stock Plans for the six months ended June 30, 2019 . Restricted Stock Units For the six months ended June 30, 2019 , the Board of Directors granted restricted stock units (“RSUs”) under the 2013 Plan for an aggregate of approximately 878,000 shares of Common Stock to members of the Board of Directors, officers and employees of the Company. These RSUs vest over periods ranging from 12 to 36 months from the respective grant dates and the awards are subject to forfeiture upon termination of employment or service on the Board of Directors. Based on the weighted average fair market value of the Common Stock on the date of grant of $5.23 per share, the aggregate fair value for the shares underlying the RSUs amounted to $4.6 million as of the grant date that will be recognized as compensation cost over the vesting period. Accordingly, compensation expense of approximately $0.5 million and $0.2 million was recognized for the three months ended June 30, 2019 and 2018 , respectively. Compensation expense of approximately $1.0 million and $0.4 million was recognized for the six months ended June 30, 2019 and 2018, respectively. As of June 30, 2019, the unrecognized expense of $3.7 million is expected to be charged to expense on a straight-line basis as the RSUs vest over a weighted-average period of approximately 2.2 years . Stock Options On February 13, 2019, the Board of Directors authorized an increase of approximately 2.6 million shares available for grant under the 2013 Plan. For the six months ended June 30, 2019 , the Board of Directors granted stock options for the purchase of an aggregate of approximately 0.5 million shares of Common Stock at an exercise prices that were equal to or greater than the fair market value of the Common Stock on the date of grant.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES In December 2017, the U.S. Tax Cuts and Jobs Act of 2017 (“Tax Act”) was enacted into law which significantly revises the Internal Revenue Code of 1986, as amended. The Tax Act, among other things, contains significant changes to corporate taxation, including a flat corporate tax rate of 21% , limitation of the tax deduction for interest expense to 30% of adjusted earnings, limitation of the deduction for newly generated net operating losses to 80% of current year taxable income and elimination of net operating loss carrybacks, one time taxation of offshore earnings at reduced rates regardless of whether they are repatriated (the “Transition Tax”), future taxation of certain classes of offshore earnings regardless of whether they are repatriated, immediate deductions for certain new investments instead of deductions for depreciation expense over time, and modifying or repealing many business deductions and credits beginning in 2018. The imposition of the Transition Tax may reduce or eliminate U.S. federal deferred taxes on the unremitted earnings of the Company’s foreign subsidiaries. However, the Company may still be liable for withholding taxes, state taxes, or other income taxes that might be incurred upon the repatriation of foreign earnings. The Company has not made any provision for additional income taxes on undistributed earnings of its foreign subsidiaries. For the three months ended June 30, 2019 and 2018 , our effective rate was 13.2% and (2.2)% , respectively. For the six months ended June 30 2019 and 2018, our effective tax rate was 7.7% and (5.1)% , respectively. Our income tax expense was attributable to earnings in foreign jurisdictions subject to income taxes. For both the three and six months ended June 30, 2019 and 2018 , no income tax expense was recorded in the United States as a result of historical net operating losses being incurred. The Company did not have any material changes to its conclusions regarding valuation allowances for deferred income tax assets or uncertain tax positions for the three months ended June 30, 2019 and 2018 .

Rimini I Litigation In January 2010, certain subsidiaries of Oracle Corporation (together with its subsidiaries individually and collectively, “Oracle”) filed a lawsuit, Oracle USA, Inc. et al. v. Rimini Street, Inc. et al. (United States District Court for the District of Nevada) (“Rimini I”), against the Company and its Chief Executive Officer, Seth Ravin, alleging that certain of the Company’s processes violated Oracle’s license agreements with its customers and that the Company committed acts of copyright infringement and violated other federal and state laws. The litigation involved the Company’s business processes and the manner in which the Company provided services to its clients. To provide software support and maintenance services to its clients, the Company requests access to a separate environment for developing and testing the updates to the software programs. Prior to July 2014, PeopleSoft, J.D. Edwards, and Siebel clients switching from Oracle to the Company’s enterprise software support were given a choice of two models for hosting the development and testing environment for their software: the environment could be hosted on the client’s servers or on the Company’s servers. In addition to other allegations, Oracle challenged the Rimini Street-hosted model for certain Oracle license agreements with its customers that contained site-based restrictions. Oracle alleged that its license agreements with these customers restrict licensees’ rights to provide third parties, such as the Company, with copies of Oracle software and restrict where a licensee may physically install the software. Oracle alleged that, in the course of providing services, the Company violated such license agreements and illegally downloaded software and support materials without authorization. Oracle further alleged that the Company impaired its computer systems in the course of downloading materials for the Company’s clients. Oracle filed amended complaints (together, “Oracle’s amended complaint”) in April 2010 and June 2011. Specifically, Oracle’s amended complaint asserted the following causes of action: copyright infringement; violations of the Federal Computer Fraud and Abuse Act; violations of the Computer Data Access and Fraud Act; violations of Nevada Revised Statute 205.4765; breach of contract; inducing breach of contract; intentional interference with prospective economic advantage; negligent interference with prospective economic advantage; unfair competition; trespass to chattels; unjust enrichment/restitution; unfair practices; and a demand for an accounting. Oracle’s amended complaint sought the entry of a preliminary and permanent injunction prohibiting the Company from copying, distributing, using, or creating derivative works based on Oracle Software and Support Materials except as allowed by express license from Oracle; from using any software tool to access Oracle Software and Support Materials; and from engaging in other actions alleged to infringe Oracle’s copyrights or were related to its other causes of action. The parties conducted extensive fact and expert discovery from 2010 through mid-2012. In March and September 2012, Oracle filed two motions seeking partial summary judgment as to, among other things, its claim of infringement of certain copyrighted works owned by Oracle. In February 2014, the District Court issued a ruling on Oracle’s March 2012 motion for partial summary judgment (i) granting summary judgment on Oracle’s claim of copyright infringement as it related to two of the Company’s PeopleSoft clients and (ii) denying summary judgment on Oracle’s claim with respect to one of the Company’s J.D. Edwards clients and one of the Company’s Siebel clients. The parties stipulated that the licenses among clients were substantially similar for purposes of the Rimini I action. In August 2014, the District Court issued a ruling on Oracle’s September 2012 motion for partial summary judgment (i) granting summary judgment on Oracle’s claim of copyright infringement as it relates to Oracle Database and (ii) dismissing the Company’s first counterclaim for defamation, business disparagement and trade libel and the Company’s third counterclaim for unfair competition. In response to the February 2014 ruling, the Company revised its business practices to eliminate the processes determined to be infringing. This process was completed no later than July 2014. A jury trial in Rimini I commenced in September 2015. On October 13, 2015, the jury returned a verdict against the Company finding that (i) the Company was liable for innocent copyright infringement, (ii) the Company and Mr. Ravin were each liable for violating certain state computer access statutes, (iii) Mr. Ravin was not liable for copyright infringement, and (iv) neither the Company nor Mr. Ravin were liable for inducing breach of contract or intentional interference with prospective economic advantage. The jury determined that the copyright infringement did not cause Oracle to suffer lost profits, that the copyright infringement was not willful, and did not award punitive damages. Following post-trial motions, Oracle was awarded a final judgment of $124.4 million in October 2016, consisting of copyright infringement damages based on the fair market value license damages theory, damages for violation of certain state computer access statutes, prejudgment interest, and attorneys’ fees and costs. In addition, the District Court entered a permanent injunction prohibiting the Company from using certain processes. The Company accounted for the $124.4 million judgment to Oracle by recording accrued legal settlement expense of (i) $100.0 million for the year ended December 31, 2014, (ii) $21.4 million for the year ended December 31, 2015, and (iii) pre-judgment interest of $3.0 million for the period from January l, 2016 through October 31, 2016. Appeal of Rimini I Litigation On October 31, 2016, the Company paid the full judgment amount of approximately $124.4 million to Oracle, and appealed the case to the United States Court of Appeals for the Ninth Circuit (the “Court of Appeals”) to appeal findings (i) and (ii) above as well as the injunction and attorneys’ fee award, non-taxable expenses, and interest. With respect to the injunction entered by the District Court, the Company argued on appeal that the injunction was vague and contains overly broad language that could be read to cover some of the Company’s current business practices that were not adjudicated to be infringing at trial and the injunction should not have been issued under applicable law. On December 6, 2016, the Court of Appeals granted the Company’s emergency motion for a stay of the permanent injunction pending resolution of the underlying appeal and agreed to consider the appeal on an expedited basis. The Court of Appeals heard argument on July 13, 2017. On January 8, 2018, the Court of Appeals reversed certain awards totaling $50.3 million made in Oracle’s favor during and after the Company’s 2015 jury trial in Rimini I and vacated and remanded others, including the injunction that had previously been stayed by the Court of Appeals on December 6, 2016, and all awards and judgments against Mr. Ravin. The Court of Appeals reversed awards previously paid by the Company as part of the $124.4 million judgment, consisting of an award under state computer access statutes and taxable expenses and interest totaling $21.3 million , Oracle’s attorneys’ fees of $28.5 million (that was subsequently remanded to the District Court), and post-judgment interest of $0.5 million . The Court of Appeals also vacated and remanded the injunction originally ordered by the District Court. Although the Court of Appeals affirmed the findings of infringement against Rimini (which the jury had found to be “innocent” infringement) for the processes that the Company ceased using no later than July 2014, it stated in the opinion that the Company “provided third-party support for Oracle's enterprise software, in lawful competition with Oracle's direct maintenance services.” As mandated by the Court of Appeals, on March 30, 2018 Oracle paid the Company $21.5 million for the reversal of the award under state computer access statutes and taxable expenses and interest totaling $21.3 million , and post-judgment interest of $0.2 million . Due to collection of this award in cash, the Company recognized a recovery of the 2016 judgment for $21.3 million and interest income of $0.2 million for the year ended December 31, 2018. Additionally, in May 2018, by stipulation of the parties, Oracle deposited $ 28.5 million into an escrow account with the District Court pending a decision by the District Court on the remanded attorneys’ fees award. On August 14, 2018, the District Court (i) imposed an injunction that was substantially identical to the injunction that the Court of Appeals had vacated in January 2018, and (ii) again awarded Oracle $28.5 million in attorneys’ fees, which were paid by funds deposited by Oracle with the District Court in May 2018. On August 16, 2018, the Company filed a notice of appeal of the District Court’s renewed injunction and its decision to return the $28.5 million attorneys’ fee award to Oracle. The Company also filed in the District Court a motion to stay the injunction pending appeal. On September 11, 2018, the District Court denied the motion, but granted a temporary 60-day stay for the Company to seek a stay with the Court of Appeals. On September 14, 2018, the Company filed a motion with the Court of Appeals, seeking a stay of the permanent injunction pending appeal and requesting a decision before the expiration of the temporary stay entered by the District Court. On November 5, 2018, the Court of Appeals denied the Company’s motion for a stay pending appeal of the injunction issued by the District Court without addressing the merits of the Company’s appeal, and it confirmed the briefing schedule for the appeal. The Company is pursuing an appeal of the injunction and the attorneys’ fee award. The Company has incurred additional expenses in the range of 1% to 2% of revenue for additional labor costs because, as drafted, the injunction contains language that could be read to cover some current support practices that are being litigated in the “Rimini II” lawsuit (described below) and that have not been found to be infringing. Briefing on the appeal to the Court of Appeals was completed on March 14, 2019, and on July 12, 2019, the Court of Appeals heard oral arguments on the appeal. The Company does not expect a ruling from the Court of Appeals until December 2019 or January 2020, but the opinion could be issued before or after these dates. As long as the injunction is still in place, Oracle may file contempt proceedings against the Company at any time to attempt to enforce its interpretation of the injunction or if it has reason to believe the Company is not in compliance with express terms of the injunction. T he Company believes that it is in compliance with the terms of the injunction insofar as they are comprehensible and within the scope of the judgment in Rimini I. On February 27, 2019, Oracle filed in the District Court a motion to reopen discovery in Rimini I and a motion to modify the protective order in Rimini II to permit Oracle to use discovery from Rimini II in Rimini I, in a purported effort to investigate whether the Company is complying with the injunction. On April 4, 2019, the District Court granted Oracle’s motion to reopen discovery in Rimini I, and on May 14, 2019, the District Court granted Oracle’s motion to modify the protective order in Rimini II to permit Oracle to use discovery from that case in Rimini I. Pursuant to the discovery scheduling order issued in Rimini I, Oracle is permitted to conduct limited discovery regarding Rimini’s compliance with the injunction. Discovery is set to close on October 8, 2019, and the deadline for Oracle to file an order to show cause for contempt is October 20, 2019. Petition for Rehearing En Banc and Appeal to the United States Supreme Court In January 2018, the Company filed a petition for rehearing en banc with the Court of Appeals regarding two other components of the final judgment awarded to Oracle. First, the Company asked the Court of Appeals to rehear the calculation of prejudgment interest, arguing that the District Court set the interest rate using a date that precedes the filing of Oracle's complaint, which resulted in an additional judgment amount of approximately $20.2 million that was paid by the Company to Oracle in October 2016. Second, the Company asked the Court of Appeals to rehear the award of non-taxable expenses, arguing that this decision is in direct conflict with decisions in other federal circuit courts and decisions of the Supreme Court of the United States (the “U.S. Supreme Court”) and resulted in the Company paying approximately $12.8 million that it would not have had to pay in other court jurisdictions. The Court of Appeals denied the petition for rehearing en banc on March 2, 2018, and the mandate was issued on March 13, 2018. On May 31, 2018, the Company filed a petition for writ of certiorari in the U.S. Supreme Court appealing the decision of the Court of Appeals on the non-taxable expenses issue. On September 27, 2018, the U.S. Supreme Court granted the Company’s petition for a writ of certiorari . Briefing on the Company’s appeal was completed in early 2019, and a hearing on the appeal was held on January 14, 2019. On March 4, 2019, the U.S. Supreme Court issued a unanimous decision reversing earlier decisions by the lower courts and ruling that Oracle must return approximately $12.8 million in non-taxable expenses that the Company had previously paid to Oracle (plus interest of $0.2 million ). As mandated by the U.S. Supreme Court, on April 5, 2019, Oracle paid the Company $13.0 million (the principal amount plus post-judgment interest). The award received by the Company will be required to be shared on a pro rata basis with an insurance company that previously paid for part of the judgment and reimbursed a portion of defense costs after deducting the costs of all of our past and pending appeal and remand proceedings in Rimini I. As a result of the U.S. Supreme Court decision, the Company recognized a recovery of the non-taxable expenses for $12.8 million and interest income of $0.2 million for the six months ended June 30, 2019, excluding any contractual amounts due to the insurance company. Rimini II Litigation In October 2014, the Company filed a separate lawsuit, Rimini Street Inc. v. Oracle Int‘l Corp. (United States District Court for the District of Nevada) (“Rimini II”), against Oracle seeking a declaratory judgment that the Company’s revised development processes, in use since at least July 2014, do not infringe certain Oracle copyrights. In February 2015, Oracle filed a counterclaim alleging copyright infringement, which included (i) the same allegations asserted in Rimini I but limited to clients not addressed in Rimini I, and (ii) new allegations that the Company’s revised support processes also infringe Oracle copyrights. Oracle’s counterclaim also included allegations of violation of the Lanham Act, intentional interference with prospective economic advantage, breach of contract and inducing breach of contract, unfair competition, and unjust enrichment/restitution. It also sought an accounting. On February 28, 2016, Oracle filed amended counterclaims adding allegations of violation of the Digital Millennium Copyright Act. On December 19, 2016, the Company filed an amended complaint against Oracle asking for a declaratory judgment of non-infringement of copyright and alleging intentional interference with contract, intentional interference with prospective economic advantage, violation of the Nevada Deceptive Trade Practices Act, violation of the Lanham Act, and violation of California Business & Professions Code §17200 et seq. On January 17, 2017, Oracle filed a motion to dismiss the Company’s amended claims and filed its third amended counterclaims, adding three new claims for a declaratory judgment of no intentional interference with contractual relations, no intentional interference with prospective economic advantage, and no violation of California Business & Professions Code §17200 et seq. On February 14, 2017, the Company filed its answer and motion to dismiss Oracle’s third amended counterclaim. On March 7, 2017, Oracle filed a motion to strike the Company’s copyright misuse affirmative defense. By stipulation of the parties, the District Court granted the Company’s motion to file its third amended complaint to add claims arising from Oracle’s purported revocation of access by the Company to its support websites on behalf of the Company’s clients, which was filed and served on May 2, 2017. By agreement of the parties, Oracle filed its motion to dismiss the Company’s third amended complaint on May 30, 2017, and the Company’s opposition was filed on June 27, 2017, and Oracle’s reply was filed on July 11, 2017. On September 22, 2017, the District Court issued an order granting in part and denying in part the Company’s motion to dismiss Oracle’s third amended counterclaims. The District Court granted the Company’s motion to dismiss Oracle's intentional interference with prospective economic advantage and unjust enrichment counterclaims. On October 5, 2017, Oracle filed a motion for reconsideration of the District Court’s September 22, 2017 Order. The Company filed its opposition to Oracle’s motion for reconsideration on October 19, 2017. Oracle filed its reply to its motion for reconsideration on October 26, 2017. On November 7, 2017, the District Court issued an order granting in part and denying in part Oracle’s motion to dismiss the Company’s third amended complaint. The District Court granted Oracle’s motion to dismiss as to the Company’s third cause of action for a declaratory judgment that Oracle has engaged in copyright misuse, fifth cause of action for intentional interference with prospective economic advantage; sixth cause of action for a violation of Nevada’s Deceptive Trade Practices Act under the “bait and switch” provision of NRS § 598.0917; and seventh cause of action for violation of the Lanham Act. The District Court denied Oracle’s motion as to the Company’s causes of action for intentional interference with contractual relations, violation of Nevada Deceptive Trade Practices Act, under the “false and misleading” provision of NRS § 598.0915(8) and unfair competition. On November 17, 2017 the District Court denied Oracle’s motion for reconsideration of the District Court’s September 22, 2017 Order. On June 5, 2018, the District Court denied the Company’s motion for reconsideration of the District Court’s November 7, 2017 Order. Fact discovery with respect to the above action substantially ended by March 2018, and expert discovery ended in September 2018. Briefing on the parties’ motions for summary judgment was completed December 14, 2018, and the parties await the District Court’s ruling on those motions. On February 27, 2019, Oracle filed a motion to modify the protective order to permit Oracle to use discovery from Rimini II in Rimini I, in connection with injunction compliance issues. On May 14, 2019, the District Court granted Oracle’s motion, permitting Oracle to use in Rimini I the discovery gathered in Rimini II. There is currently no trial date scheduled, and the Company does not expect a trial to occur in this matter earlier than 2021, but the trial could occur earlier or later than that. At this time, the Company does not have sufficient information regarding possible damages exposure for the counterclaims asserted by Oracle or possible recovery by the Company in connection with its claims against Oracle. Both parties are seeking injunctive relief in addition to monetary damages in this matter. As a result, an estimate of the range of loss cannot be reasonably determined. The Company also believes that an award for damages is not probable, so no accrual has been made as of June 30, 2019. Other Litigation From time to time, the Company may be a party to litigation and subject to claims incident to the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on its business. Regardless of the outcome, litigation can have an adverse impact on the Company because of judgment, defense and settlement costs, diversion of management resources and other factors. At each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under ASC 450, Contingencies . Legal fees are expensed as incurred. Insurance Settlement Agreement On March 31, 2017, the Company entered into a Settlement Agreement, Release and Policy Buyback Agreement (the “Settlement Agreement”) with an insurance company that previously provided coverage for the defense costs related to the Oracle litigation referred to as Rimini II. The Settlement Agreement provided for aggregate payments to the Company of $24.0 million and resulted in the termination of coverage under the insurance policies. Prior to execution of the Settlement Agreement, the insurance company reimbursed the Company an aggregate of $4.7 million of defense costs, and pursuant to the settlement agreed to make an additional payment to the Company of $19.3 million that was received in April 2017. In April 2017, the Company paid $0.6 million of settlement expenses, and the remaining $18.7 million of settlement proceeds was used to make a mandatory $14.1 million principal payment, and a $4.6 million make-whole applicable premium payment due to the Lenders pursuant to the terms of the Credit Facility discussed in Note 4. The Settlement Agreement was initially accounted for by recognizing a deferred insurance settlement liability for $19.3 million . This deferred insurance settlement liability was reduced as legal defense costs related to Rimini II were incurred subsequent to March 31, 2017. Accordingly, the deferred insurance settlement liability was eliminated as of March 31, 2018 due to legal defense costs of $11.3 million incurred for the year ended December 31, 2017, resulted in a reduction of the deferred insurance settlement liability to $8.0 million as of December 31, 2017. There was no remaining liability as of December 31, 2018. Governmental Inquiry On March 2, 2018, the Company received a federal grand jury subpoena, issued from the United States District Court for the Northern District of California, requesting the Company produce certain documents relating to specified support and related operational practices. The Company is cooperating with this inquiry and has complied with the related document request. Proceeds from the U.S. Supreme Court Decision On April 5, 2019, the Company received payment from Oracle of $13.0 million related to the U.S. Supreme Court ruling on March 4, 2019, which reversed earlier decisions by the lower courts that Oracle must return approximately $12.8 million in non-taxable expenses previously paid by the Company plus post-judgment interest. The award is required to be shared with an insurance company on pro rata basis, whereby the insurance company may be entitled to 60% of the award after deducting the Company's costs for all appeal and remand proceedings. As a result, the Company has recognized a recovery of non-taxable expenses of $12.8 million and recorded interest income of $0.2 million for the six months ended June 30, 2019. The Company also recognized costs of $4.3 million , during the six months ended June 30, 2019, reflecting the current estimate of the amounts owed to the insurance company to date pursuant to the Settlement Agreement described above. This liability is subject to decrease as additional costs related to any future Rimini I appeal and remand proceedings are incurred. Liquidated Damages The Company enters into agreements with clients that contain provisions related to liquidated damages that would be triggered in the event that the Company is no longer able to provide services to these clients. The maximum cash payments related to these liquidated damages is approximately $31.4 million and $30.4 million as of June 30, 2019 and December 31, 2018 , respectively. To date, the Company has not incurred any costs as a result of such provisions and has not accrued any liabilities related to such provisions in these unaudited condensed consolidated financial statements.

Earnings Per Share [Abstract]
EARNINGS (LOSS) PER SHARE	EARNINGS (LOSS) PER SHARE We compute earnings per share in accordance with ASC Topic 260, Earnings per Share (“ASC 260”), which requires earnings per share for each class of stock to be calculated using the two-class method. The holders of Series A Preferred Stock are entitled to participate in Common Stock dividends, if and when declared, on a one -to-one per-share basis. Accordingly, in periods in which the Company has net income, earnings per share will be computed using the two-class method whereby the pro rata dividends on Common Stock that are also distributable to the holders of Series A Preferred Stock will be deducted from earnings applicable to common stockholders, regardless of whether a dividend is declared for such undistributed earnings. Under the two-class method, earnings for the reporting period are allocated between the holders of our Common Stock and the Series A Preferred Stock based on their respective participation rights in undistributed earnings. Basic earnings per Common Stock share is computed by dividing net income attributable to common stockholders by the weighted average number of shares of basic Common Stock outstanding. Net income allocated to the holders of our Series A Preferred Stock is calculated based on the shareholders’ proportionate share of the weighted average shares of Common Stock outstanding on an if-converted basis. Diluted earnings per Common Stock share is calculated by adjusting the basic earnings per Common Stock share for the effects of potential dilutive Common Stock shares outstanding such as stock options, restricted stock units and warrants. For both the three months and six months ended June 30, 2019 and 2018 , basic and diluted net earnings per share of Common Stock were computed by dividing the net income attributable to common stockholders by the weighted average number of common shares outstanding during the respective periods. The following table sets forth the computation of basic and diluted net income attributable to common stockholders for both the three and six months ended June 30, 2019 and 2018 (in thousands, except per share amounts): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Income attributable to common stockholders: Net income (loss) $ 4,087 $ (25,446 ) $ 15,911 $ (21,939 ) Dividends and accretion related to Series A Preferred Stock: Cash dividends declared (3,747 ) — (7,340 ) — PIK dividends declared (1,124 ) — (2,202 ) — Accretion of discount (1,449 ) — (2,808 ) — (2,233 ) (25,446 ) 3,561 (21,939 ) Undistributed earnings allocated using the two-class method — — (655 ) — Net income (loss) attributable to common stockholders $ (2,233 ) $ (25,446 ) $ 2,906 $ (21,939 ) 2019 2018 2019 2018 Weighted average number of shares of Common Stock outstanding 65,535 59,800 65,080 59,534 Additional shares outstanding if Series A Preferred Stock is converted to Common Stock 14,989 — 14,681 — Total shares outstanding if Series A Preferred Stock is converted to Common Stock 80,524 59,800 79,761 59,534 Percentage of shares allocable to Series A Preferred Stock 18.6 % — % 18.4 % — % Weighted average number of shares of Common Stock outstanding: Basic 65,535 59,800 65,080 59,534 Effect of dilutive securities: Origination Agent warrants — — — — Stock options — — 4,028 — Restricted stock units — — 94 — Diluted 65,535 59,800 69,202 59,534 Net earnings (loss) per share attributable to common stockholders: Basic $ (0.03 ) $ (0.43 ) $ 0.04 $ (0.37 ) Diluted $ (0.03 ) $ (0.43 ) $ 0.04 $ (0.37 ) For the six months ended June 30, 2019, share-based awards for approximately 21.5 million shares were not included in the computation of diluted earnings per share as they were anti-dilutive. For the three months ended June 30, 2019 and 2018 as well as the six months ended June 30, 2018, basic and diluted loss per share attributable to common stockholders were the same because all Common Stock equivalents were anti-dilutive. As of June 30, 2019 and 2018, the following potential Common Stock equivalents were excluded from the computation of diluted net (loss) per share for the respective periods ending on these dates since the impact of inclusion was anti-dilutive (in thousands): 2019 2018 Series A Preferred Stock 15,297 — Restricted stock units 918 176 Stock options 10,076 12,706 Warrants 18,128 18,128 Total 44,419 31,010

FINANCIAL INSTRUMENTS AND SIGNIFICANT CONCENTRATIONS	FINANCIAL INSTRUMENTS AND SIGNIFICANT CONCENTRATIONS Fair Value Measurements Fair value is defined as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. When determining fair value, the Company considers the principal or most advantageous market in which it transacts, and considers assumptions that market participants would use when pricing the asset or liability. Additional information on fair value measurements is included in Note 13 to the Company’s consolidated financial statements for the year ended December 31, 2018, included in the 2018 Form 10-K. As discussed in Note 5, the fair value for our Series A Preferred Stock issuances on June 20, 2019 and March 7, 2019 were determined to be $3.0 million and $5.3 million , respectively, which were utilized to determine the basis for allocating the net proceeds. The fair value was determined by utilizing a combination of a discounted cash flow methodology related to funds generated by the Series A Preferred Stock, along with the BSM option-pricing model in relation to the conversion feature. Key assumptions applied for the discounted cash flow and BSM analysis included (i) three different scenarios whereby the Series A Preferred Stock would remain outstanding between 4 and 5 years along with a probability weighting assigned to each scenario, (ii) an implied yield of the Series A Preferred Stock ranging from 20.9% to 22.9% calibrated to the transaction values as of June 20, 2019 and March 7, 2019, respectively, (iii) risk-free interest rates of 1.72% and 2.44% , and (iv) historical volatility of 30.0% . For the three and six months ended June 30, 2018, the Company’s embedded derivative liability was the only liability that was carried at fair value on a recurring basis and was classified within Level 3 of the fair value hierarchy. Details of the embedded derivative, including valuation methodology and key assumptions and estimates used, were disclosed in Part II, Item 8 of our 2018 Form 10-K, in the Company's audited consolidated financial statements for the year ended December 31, 2018, within Note 5. All embedded derivative liabilities were eliminated on July 19, 2018 upon termination of the Credit Facility. These embedded derivatives had an aggregate fair value of $7.8 million and $1.6 million as of June 30, 2018 and December 31, 2017, respectively. The change in fair value of embedded derivatives resulted in the Company recognizing a loss of $6.7 million and $6.2 million for the three and six months ended June 30, 2018, respectively. The Company’s policy is to recognize asset or liability transfers among Level 1, Level 2 and Level 3 as of the actual date of the events or change in circumstances that caused the transfer. As of June 30, 2019, the Company does not have any assets or liabilities that are carried at fair value on a recurring basis. The carrying amounts of the Company’s financial instruments including cash and cash equivalents, restricted cash, accounts receivable, accounts payable, and accrued liabilities approximate fair values due to their short-term maturities. Based on borrowing rates currently available to the Company for debt with similar terms, the carrying value of capital lease obligations approximate fair value as of the respective balance sheet dates. Significant Concentrations The Company attributes revenues to geographic regions based on the location of its customers’ contracting entity. The following table shows revenues by geographic region (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 United States of America $ 44,019 $ 39,297 $ 86,890 $ 79,042 International 23,937 23,352 47,326 43,412 Total $ 67,956 $ 62,649 $ 134,216 $ 122,454 No customers represented more than 10% of revenue for the both three months and six months ended June 30, 2019 and 2018 . As of June 30, 2019 and December 31, 2018 , no customers accounted for more than 10% of total net accounts receivable. Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, restricted cash, and accounts receivable. The Company maintains its cash, cash equivalents and restricted cash at high-quality financial institutions, primarily in the United States of America. Deposits, including those held in foreign branches of global banks, may exceed the amount of insurance provided on such deposits. As of June 30, 2019 and December 31, 2018 , the Company had cash, cash equivalents and restricted cash with a single financial institution for an aggregate of $42.1 million and $19.9 million , respectively. As of June 30, 2019 and December 31, 2018 , the Company had restricted cash of $0.4 million and $0.4 million , respectively. The Company has never experienced any losses related to these balances. Generally, credit risk with respect to accounts receivable is diversified due to the number of entities comprising the Company’s customer base and their dispersion across different geographies and industries. The Company performs ongoing credit evaluations on certain customers and generally does not require collateral on accounts receivable. The Company maintains reserves for potential bad debts and historically such losses are generally not significant.

Accounting Policies [Abstract]
Nature of Business	Nature of Business Rimini Street, Inc. (“the Company”) is a global provider of enterprise software support services. The Company’s subscription-based software support products and services offer enterprise software licensees a choice of solutions that replace or supplement the support products and services offered by enterprise software vendors.
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The unaudited condensed consolidated financial statements, which include the accounts of the Company and its wholly owned subsidiaries, are prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”). All significant intercompany balances and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, certain information and footnote disclosures required by GAAP for complete financial statements have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the unaudited condensed consolidated financial statements have been included. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements for the year ended December 31, 2018 , included in the Company’s 2018 Annual Report on Form 10-K as filed with the SEC on March 14, 2019 (the “ 2018 Form 10-K”). The accompanying condensed consolidated balance sheet and related disclosures as of December 31, 2018 have been derived from the Company’s audited financial statements. The Company’s financial condition as of June 30, 2019 , and operating results for both the three and six months ended June 30, 2019 are not necessarily indicative of the financial condition and results of operations that may be expected for any future interim period or for the year ending December 31, 2019 .
Use of Estimates	Use of Estimates The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in its consolidated financial statements and accompanying notes. The Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes are reasonable under the circumstances, to determine the carrying values of assets and liabilities that are not readily apparent from other sources. The Company’s significant accounting estimates include, but are not necessarily limited to, accounts receivable, valuation assumptions for stock options, deferred income taxes and the related valuation allowances, and the evaluation and measurement of contingencies. To the extent there are material differences between the Company’s estimates and the actual results, the Company’s future consolidated results of operation may be affected.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Standards. The following accounting standards were adopted during the first quarter of fiscal year 2019 : In May 2017, the FASB issued ASU No. 2017-9, Compensation-Stock Compensation: Scope of Modification Accounting , which provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This standard does not change the accounting for modifications of share-based payment awards but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. This standard did not have a material impact for the Company during the three and six months ended June 30, 2019. In August 2018, the SEC adopted a final rule that extends the current annual requirement to disclose changes in stockholders’ equity to interim periods and also requires interim disclosure of dividends per share for each class of shares (including the Company’s Series A Preferred Stock). These disclosure provisions became effective beginning in the first quarter of 2019, whereby the Company is required to disclose changes in stockholders’ deficit for the current and comparative fiscal quarters as well as the current and comparative year-to-date periods presented in interim condensed consolidated financial statements. The Company has provided an unaudited condensed consolidated statement of stockholders' deficit for the three and six months ended June 30, 2019 and 2018. The following accounting standards are not yet effective; Management has not completed its evaluation to determine the impact that adoption of these standards will have on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which supersedes nearly all existing revenue recognition standards under U.S. GAAP. The new standard provides a five-step process for recognizing revenue that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard also requires expanded qualitative and quantitative disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The new standard allows for two transition methods: (i) a full retrospective method applied to each prior reporting period presented, or (ii) a modified retrospective method applied with the cumulative effect of adoption recognized on adoption date. The Company currently intends to adopt this standard using the full retrospective method. Due to the Company’s emerging growth company status and certain elections made, the new standard is effective for the Company in fiscal year 2019. As an emerging growth company for interim reporting purposes, we can elect to initially apply the standard either in the year of adoption or in the subsequent year. The Company has elected to adopt the standard for interim reporting purposes beginning in the first quarter of fiscal 2020. As a result of this election, fiscal year 2019 interim periods will continue to be reported under legacy GAAP while full year 2019 results will be reported under the new standard. We have made significant progress in our analysis of how the standard will impact our revenue, but we have not completed our evaluation and therefore the full impact upon adoption of this standard is not known and cannot be reasonably estimated. Based on our preliminary evaluation to date, we believe that the primary change will be the accelerated timing of revenue recognition for certain contracts due to the removal of the current limitation associated with revenue contingent upon the future delivery of support services. In addition, we expect to capitalize costs incurred to obtain new client contracts, which is primarily comprised of sales commissions. Such costs, which are expensed as incurred under the current standard, will be capitalized and amortized over their estimated useful lives under the new standard. We will complete our evaluation during fiscal year 2019. In February 2016, the FASB issued ASU No. 2016-02, Leases , which requires organizations that lease assets (“lessees”) to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases with lease terms of more than 12 months. Under the new standard, both finance and operating leases will be required to be recognized on the balance sheet. Additional quantitative and qualitative disclosures, including significant judgments made by management, will also be required. The standard will be effective for the Company beginning in the first quarter of fiscal 2020. Early adoption is permitted, and the new standard was initially required to be adopted retrospectively to each prior reporting period presented upon initial adoption. However, in July 2018 the FASB issued ASU No. 2018-11 Targeted Improvements , which provides lessees the option to apply the new leasing standard to all open leases as of the adoption date by recognizing a cumulative-effect adjustment to accumulated deficit in the period of adoption without restating prior periods. The Company is still evaluating which transition approach will be implemented upon its adoption of ASU No. 2016-02.
Earnings Per Share	We compute earnings per share in accordance with ASC Topic 260, Earnings per Share (“ASC 260”), which requires earnings per share for each class of stock to be calculated using the two-class method. The holders of Series A Preferred Stock are entitled to participate in Common Stock dividends, if and when declared, on a one -to-one per-share basis. Accordingly, in periods in which the Company has net income, earnings per share will be computed using the two-class method whereby the pro rata dividends on Common Stock that are also distributable to the holders of Series A Preferred Stock will be deducted from earnings applicable to common stockholders, regardless of whether a dividend is declared for such undistributed earnings. Under the two-class method, earnings for the reporting period are allocated between the holders of our Common Stock and the Series A Preferred Stock based on their respective participation rights in undistributed earnings. Basic earnings per Common Stock share is computed by dividing net income attributable to common stockholders by the weighted average number of shares of basic Common Stock outstanding. Net income allocated to the holders of our Series A Preferred Stock is calculated based on the shareholders’ proportionate share of the weighted average shares of Common Stock outstanding on an if-converted basis. Diluted earnings per Common Stock share is calculated by adjusting the basic earnings per Common Stock share for the effects of potential dilutive Common Stock shares outstanding such as stock options, restricted stock units and warrants.
