Accounting Policies [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS ChaSerg Technology Acquisition Corp. (the “Company”) was incorporated in Delaware on May 21, 2018. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company’s subsidiaries are comprised of CS Merger Sub 1 Inc., a wholly owned subsidiary of the Company incorporated on November 12, 2019 as a California corporation (“Merger Sub 1”), and CS Merger Sub 2 LLC., a wholly owned subsidiary of the Company incorporated on November 8, 2019 as a Delaware limited liability corporation (“Merger Sub 2”). Although the Company is not limited to a particular industry or sector for purposes of consummating a Business Combination, the Company intends to focus its search on companies in the technology industry. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of December 31, 2019, the Company had not commenced any operations. All activity for the period from May 21, 2018 (inception) through December 31, 2019 relates to the Company’s formation, its initial public offering (“Initial Public Offering”), which is described below, identifying a target company for a Business Combination and the proposed acquisition of Grid Dynamics International, Inc., a California corporation (“Grid Dynamics”) (see Note 6). The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The registration statement for the Company’s Initial Public Offering was declared effective on October 4, 2018. On October 10, 2018, the Company consummated the Initial Public Offering of 20,000,000 units (“Units” and, with respect to the Class A common stock included in the Units offered, the “Public Shares”) at $10.00 per Unit, generating gross proceeds of $200,000,000, which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 600,000 units (the “Placement Units”) at a price of $10.00 per Placement Unit in a private placement to ChaSerg Technology Sponsor LLC, a Delaware limited liability company (the “Sponsor”) and Cantor Fitzgerald & Co. (“Cantor”), generating gross proceeds of $6,000,000, which is described in Note 4. Following the closing of the Initial Public Offering on October 10, 2018, an amount of $200,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Placement Units was placed in a trust account (“Trust Account”) which was invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 180 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account, as described below. On October 25, 2018, in connection with the underwriters’ election to partially exercise their over-allotment option, the Company sold an additional 2,000,000 Units at $10.00 per Unit and sold an additional 40,000 Placement Units at $10.00 per Placement Unit, generating total gross proceeds of $20,400,000. Following such closing, an additional $20,000,000 of net proceeds ($10.00 per Unit) was deposited in the Trust Account, resulting in $220,000,000 ($10.00 per Unit) held in the Trust Account. Transaction costs amounted to $12,821,311, consisting of $4,400,000 of underwriting fees, $7,700,000 of deferred underwriting fees and $721,311 of legal and other costs. In addition, as of December 31, 2019, $141,583 of cash was held outside of the Trust Account and is available for working capital purposes. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of Placement Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act 1940, as amended (the “Investment Company Act”). The Company will provide its holders of the outstanding Public Shares (the “Public Stockholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account ($10.00 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its franchise and income tax obligations). The per-share amount to be distributed to Public Stockholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 6). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. The Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transactions is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the Company’s Sponsor has agreed to vote its Founder Shares (as defined in Note 5), Placement Shares (as defined in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each Public Stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Amended and Restated Certificate of Incorporation provides that a Public Stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Public Shares, without the prior consent of the Company. The Sponsor has agreed (a) to waive its redemption rights with respect to its Founder Shares, Placement Shares and Public Shares held by it in connection with the completion of a Business Combination and (b) not to propose an amendment to the Amended and Restated Certificate of Incorporation (i) that would affect the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if the Company does not complete a Business Combination or (ii) with respect to any other provision relating to stockholders’ rights or pre-business combination activity, unless the Company provides the Public Stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment. The Company has until April 9, 2020 to consummate a Business Combination (the “Combination Period”). If the Company is unable to complete a Business Combination by the end of the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company to pay franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period. The Sponsor has agreed to waive its liquidation rights with respect to the Founder Shares and Placement Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Sponsor acquires Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than $10.00 per share. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.00 per share or (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (except for the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Liquidity and Going Concern As of December 31, 2019, the Company had a cash balance of approximately $142,000 and a working capital deficit of approximately $5,419,000. In addition, the Company had $224,016,036 in the Trust Account, which includes interest income of approximately $4,016,000 from the Company’s investments in the Trust Account which is available to the Company to pay its tax obligations. The Company intends to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less taxes payable and deferred underwriting commissions) to complete its initial Business Combination. To the extent necessary, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required, up to $1,500,000. Such loans may be convertible into units of the post Business Combination entity at a price of $10.00 per unit. The units would be identical to the Placement Units (see Note 5). If the Company’s estimates of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, the Company may have insufficient funds available to operate its business prior to a Business Combination. Moreover, the Company may need to obtain additional financing either to complete a Business Combination or because it becomes obligated to redeem a significant number of its Public Shares upon completion of a Business Combination, in which case the Company may issue additional securities or incur debt in connection with such Business Combination. In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” management has determined that the working capital deficit and mandatory liquidation and subsequent dissolution raises substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after April 9, 2020.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the SEC. Principles of consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of consolidated 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 and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future events. Accordingly, the actual results could differ significantly from the Company’s estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of December 31, 2019 and 2018. Common Stock Subject to Possible Redemption The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock, sold in the Public Offering, features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. The shares of common stock sold in the private placements do not contain these rights. Accordingly, at December 31, 2019 and 2018, 20,589,710 and 20,921,905 shares of common stock subject to possible redemption, respectively, are presented as temporary equity, outside of the stockholders’ equity section of the Company’s consolidated balance sheets. Offering Costs Offering costs consist of legal, accounting, underwriting fees and other costs incurred through the balance sheet date that are directly related to the Initial Public Offering. Offering costs amounting to $12,821,311 were charged to stockholders’ equity upon the completion of the Initial Public Offering. Income Taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2019 and 2018. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. Net Income (Loss) Per Common Share Net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. The Company has not considered the effect of warrants sold in the Initial Public Offering and private placement to purchase 11,320,000 shares of Class A common stock in the calculation of diluted income (loss) per share, since the exercise of the warrants are contingent upon the occurrence of future events and the inclusion of such warrants would be anti-dilutive. The Company’s statement of operations includes a presentation of income (loss) per share for common shares subject to redemption in a manner similar to the two-class method of income per share. Net income per common share, basic and diluted for Class A redeemable common stock is calculated by dividing the interest income earned on the Trust Account (net of applicable franchise and income taxes of approximately $1,493,000 and $341,000 for the year ended December 31, 2019 and for the period from May 21, 2018 (inception) through December 31, 2018, respectively), by the weighted average number of Class A redeemable common stock outstanding during the period. Net loss per common share, basic and diluted for Class A and Class B non-redeemable common stock is calculated by dividing the net income (loss), less income attributable to Class A redeemable common stock, by the weighted average number of Class A and Class B non-redeemable common stock outstanding for the period. Class A and Class B non-redeemable common stock includes the Founder Shares and the Placement Units as these shares do not have any redemption features and do not participate in the income earned on the Trust Account. The following table reflects the calculation of basic and diluted net income (loss) per common share: Year Ended December 31, 2019 For the Period from May 21, 2018 (inception) Through December 31, 2018 Redeemable Common Stock Numerator: Earnings allocable to Redeemable Common Stock Interest Income $ 4,664,912 $ 1,158,467 Income and Franchise Tax $ (1,493,035 ) $ (340,715 ) Net Earnings $ 3,171,877 $ 817,752 Denominator: Weighted Average Redeemable Common Stock Redeemable Common Stock, Basic and Diluted 22,000,000 21,654,321 Earnings/Basic and Diluted Redeemable Common Stock $ 0.14 $ 0.04 Non-Redeemable Common Stock Numerator: Net Loss minus Redeemable Net Earnings Net (Loss) Income $ (3,321,949 ) $ 615,364 Redeemable Net Earnings $ (3,171,877 ) $ (817,752 ) Non-Redeemable Net Loss $ (6,493,826 ) $ (202,388 ) Denominator: Weighted Average Non-Redeemable Common Stock Non-Redeemable Common Stock, Basic and Diluted (1) 6,140,000 5,733,422 Loss/Basic and Diluted Non-Redeemable Common Stock $ (1.06 ) $ (0.04 ) Note: As of December 31, 2019 and 2018, basic and diluted shares are the same as there are no securities that are dilutive to the Company’s common stockholders. (1) The weighted average non-redeemable common stock for the year ended December 31, 2019 includes the effect of 717,500 Private Units, which were issued in conjunction with the initial public offering on February 11, 2019. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times may exceed the Federal Depository Insurance Coverage of $250,000. At December 31, 2019 and 2018, the Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the accompanying consolidated balance sheets, primarily due to their short-term nature. Recent Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s consolidated financial statements.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	NOTE 5. RELATED PARTY TRANSACTIONS Founder Shares On May 30, 2018, the Sponsor purchased 5,750,000 shares (the “Founder Shares”) of the Company’s Class B common stock for an aggregate price of $25,000. The Founder Shares included an aggregate of up to 750,000 shares subject to forfeiture to the extent that the underwriters’ over-allotment option was not exercised in full or in part, so that the Sponsor would own, on an as-converted basis, 20% of the Company’s issued and outstanding shares after the Initial Public Offering (assuming the Sponsor did not purchase any Public Shares in the Initial Public Offering and excluding the Placement Units). As a result of the underwriters’ election to partially exercise their over-allotment option, 250,000 Founder Shares were forfeited and 500,000 Founder Shares are no longer subject to forfeiture. The Founder Shares will automatically convert into Class A common stock upon consummation of a Business Combination on a one-for-one basis, subject to certain adjustments, as described in Note 7. The Sponsor has agreed, subject to limited exceptions, not to transfer, assign or sell any of its Founder Shares until the earlier to occur of: (A) one year after the completion of a Business Combination or (B) subsequent to a Business Combination, (x) if the last sale price of the Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a Business Combination, or (y) the date on which the Company completes a liquidation, merger, capital stock exchange or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of common stock for cash, securities or other property. Related Party Advances During year ended December 31, 2019, the Company’s Sponsor advanced an aggregate of $20,000 to be used for working capital purposes. The advances are non-interest bearing, unsecured and due on demand. Advances amounting to $20,000 were outstanding as of December 31, 2019. Related Party Loans On May 23, 2018, the Company issued a promissory note to the Sponsor, pursuant to which the Company borrowed an aggregate of $300,000 to cover expenses related to the Initial Public Offering (the “Promissory Note”). The Promissory Note was non-interest bearing and payable on the earlier of March 31, 2019 or the completion of the Initial Public Offering. The Promissory Note was repaid upon the consummation of the Initial Public Offering on October 10, 2018. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $1,500,000 of such Working Capital Loans may be convertible into units of the post Business Combination entity at a price of $10.00 per unit. The units would be identical to the Placement Units. Convertible Promissory Note – Related Party In November 2019, the Company issued an unsecured convertible promissory note to the Sponsor, pursuant to which the Company borrowed an aggregate principal amount of $300,000. The note is non-interest bearing and payable upon the consummation of a Business Combination. The note may be converted upon consummation of a Business Combination into additional Private Units at a price of $10.00 per Unit (see below). As of December 31, 2019, there was $300,000 outstanding under the promissory note. Administrative Support Agreement The Company entered into an agreement whereby, commencing on October 10, 2018 through the earlier of the Company’s consummation of a Business Combination and its liquidation, to pay an affiliate of the Sponsor a total of $15,000 per month for office space, utilities and secretarial and administrative support. For the year ended December 31, 2019 and for the period from May 21, 2018 (inception) through December 31, 2018, the Company incurred $180,000 and $30,000 in fees for these services, respectively. At December 31, 2019 and 2018, $75,000 and $30,000 of such fees is included in accounts payable and accrued expenses in the accompanying consolidated balance sheets, respectively.

Commitments and Contingencies Disclosure [Text Block]	NOTE 6. COMMITMENTS Registration Rights Pursuant to a registration rights agreement entered into on October 4, 2018, the holders of the Founder Shares, Placement Units (including securities contained therein) and securities that may be issued upon conversion of Working Capital Loans (and any shares of Class A common stock issuable upon the exercise of the Placement Warrants and warrants that may be issued upon conversion of working capital loans and upon conversion of the Founder Shares) will be entitled to registration rights requiring the Company to register such securities for resale (in the case of the Founder Shares, only after conversion to Class A common stock). The holders of the majority of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of a Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. Notwithstanding the foregoing, the underwriters may not exercise their demand and “piggyback” registration rights after five (5) and seven (7) years after the effective date of the registration statement and may not exercise their demand rights on more than one occasion. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Underwriting Agreement The Company granted the underwriters a 45-day option to purchase up to 3,000,000 additional Units to cover over-allotments at the Initial Public Offering price less the underwriting discounts and commissions. On October 25, 2018, the underwriters elected to partially exercise their over-allotment option to purchase 2,000,000 Units at a purchase price of $10.00 per Unit. In connection with the closing of the Initial Public Offering and the over-allotment option, the underwriters were paid a cash underwriting discount $4,400,000. In addition, the underwriters are entitled to a deferred fee of $0.35 per Unit, or $7,700,000 in the aggregate. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement. Merger Agreement On November 13, 2019, the Company, Merger Sub 1 and Merger Sub 2 (collectively, the “ChaSerg Parties”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Grid Dynamics and Automated Systems Holdings Limited (“ASL”), a company incorporated in Bermuda with limited liability, solely in its capacity as representative of the stockholders of Grid Dynamics immediately prior to the consummation of the business combination. Pursuant to the Merger Agreement, (i) Merger Sub 1 will be merged with and into Grid Dynamics, with Grid Dynamics surviving the merger on the terms and subject to the conditions set forth in the Merger Agreement (the “Initial Merger”), and (ii) as part of the same overall transaction, immediately following the Initial Merger, Grid Dynamics will be merged with and into Merger Sub 2, with Merger Sub 2 surviving on the terms and subject to the conditions set forth in the Merger Agreement (the “Second Step Merger” and, together with the Initial Merger, the “Mergers”). The purchase price will be paid to Grid Dynamics stockholders as of immediately prior to the consummation of the Business Combination in a combination of stock and cash consideration. The aggregate merger consideration (the “Merger Consideration”) to be paid pursuant to the Merger Agreement will be an amount equal to: (i) $130,000,000, subject to certain reductions (the “Cash Consideration”) and (ii) 25,523,810 shares of the Company’s Class A Common Stock (the “Share Consideration”). The Cash Consideration is subject to reduction in an amount equal to: $13,500,000 multiplied by (x) the balance of the trust account (the “Trust Account”) established by the Company for the benefit of its public stockholders as at the date of the signing of the Merger Agreement minus the Available Parent Cash, divided by (y) 30% of the Trust Account balance as at the date of the signing of the Merger Agreement, where such adjustment amount can be no more than $13,500,000 and no less than $0, and is offset by an equivalent increase in the Share Consideration. The Share Consideration is subject to customary adjustment at closing by an amount of shares of the Company’s Class A Common Stock to account for changes in working capital, indebtedness and excess cash. Excess cash also includes an adjustment mechanism for funds that are used between signing and closing for specified acquisitions. The Share Consideration is also subject to adjustment for earnings before income taxes, depreciation and amortization (“EBITDA”) performance targets, whereby the Share Consideration is reduced by $1,500,000 for every $100,000 by which the estimated total EBITDA in 2019 is below $23,800,000. The post-closing adjustment of the Share Consideration is capped at 857,143 shares of the Company’s Class A Common Stock which will be placed in escrow at closing. The obligations of the parties to consummate the Merger are subject to various conditions, including, among other things: (i) the approval of Grid Dynamics’s stockholders; (ii) the approval of the Company’s stockholders at a special meeting of the Company’s stockholders; (iii) the approval of the shareholders of ASL, including Teamsun Technology (HK) Limited (“Teamsun HK”), a company listed on the Stock Exchange of Hong Kong Limited (“HKEX”); (iv) the approval of the shareholders of Beijing Teamsun Technology Co. Ltd. (“Teamsun”), including the largest stockholder of Teamsun (the “Teamsun Affiliate”); (v) the receipt of requisite government and securities exchange approvals, including approval related to the Hart-Scott Rodino Antitrust Improvements Act of 1976, as amended, and approval from the HKEX; (vi) after giving effect to the right of the Company’s public stockholders to redeem their shares of the Company’s Class A Common Stock (the “Redemption”), the Company having at least $5,000,001 in net tangible assets in the Trust Account; and (vii) after giving effect to the Redemption and the receipt of any additional equity sold by the Company, the total cash and cash equivalents of the Company shall be at least 70% of the Trust Account balance as of the date of signing of the Merger Agreement. The Merger will be consummated subject to the deliverables and provisions as further described in the Merger Agreement.

Stockholders' Equity Note [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	NOTE 7. STOCKHOLDERS’ EQUITY Preferred Stock Common Stock Class A Common Stock Class B Common Stock Holders of Class A common stock and Class B common stock will vote together as a single class on all other matters submitted to a vote of stockholders except as required by law. The shares of Class B common stock will automatically convert into shares of Class A common stock at the time of a Business Combination on a one-for-one basis, subject to adjustment. In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amounts offered in the Initial Public Offering and related to the closing of a Business Combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as-converted basis, 20% of the sum of the total number of all shares of common stock outstanding upon the completion of the Initial Public Offering (not including the shares of Class A common stock underlying the Placement Units) plus all shares of Class A common stock and equity-linked securities issued or deemed issued in connection with a Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in a Business Combination, any private placement-equivalent warrants issued, or to be issued, to any seller in a Business Combination, any private placement equivalent securities issued to the Sponsor or its affiliates upon conversion of loans made to the Company). Holders of Founder Shares may also elect to convert their shares of Class B common stock into an equal number of shares of Class A common stock, subject to adjustment as provided above, at any time. Warrants th Once the warrants become exercisable, the Company may redeem the Public Warrants: ● in whole and not in part; ● at a price of $0.01 per warrant; ● upon not less than 30 days’ prior written notice of redemption; and ● if, and only if, the reported last sale price of the Company’s Class A common stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders. ● If, and only if, there is a current registration statement in effect with respect to the shares of Class A common stock underlying such warrants. The Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Placement Warrants and the Class A common stock issuable upon the exercise of the Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Placement Warrants will be exercisable on a cashless basis and be non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of shares of Class A common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuance of Class A common stock at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the warrants. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

In assessing the realization of the deferred tax assets, management considers whether it is more likely than not that some portion of all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. For the year ended December 31, 2019 and for the period from May 21, 2018 (inception) through December 31, 2018, the change in the valuation allowance was $1,363,704 and $42,501, respectively. A reconciliation of the federal income tax rate to the Company’s effective tax rate at December 31, 2019 and 2018 is as follows: Year Ended December 31, 2019 May 21, 2018 (inception) Through December 31, 2018 Statutory federal income tax rate 21.0 % 21.0 % State taxes, net of federal tax benefit % 0.0 % Change in valuation allowance (55.0 )% 5.1 % Income tax provision (34.0 )% 26.1 % The Company files income tax returns in the U.S. federal jurisdiction in various state and local jurisdictions and is subject to examination by the various taxing authorities.

Fair Value Disclosures [Abstract]
Fair Value Measurement and Measurement Inputs, Recurring and Nonrecurring [Text Block]	NOTE 9. FAIR VALUE MEASUREMENTS The Company classifies its U. S. Treasury and equivalent securities as held-to-maturity in accordance with ASC 320 “Investments - Debt and Equity Securities.” Held-to-maturity securities are those securities which the Company has the ability and intent to hold until maturity. Held-to-maturity treasury securities are recorded at amortized cost on the accompanying consolidated balance sheets and adjusted for the amortization or accretion of premiums or discounts. At December 31, 2019, assets held in the Trust Account were comprised of $667 in cash and $224,015,369 in money market funds which are invested in U.S Treasury Securities. At December 31, 2018, assets held in the Trust Account were comprised of $24,616 in cash and $221,133,851 in U.S. Treasury Bills. During the year ended December 31, 2019, the Company withdrew $1,807,343 of interest income from the Trust account to pay its franchise and income tax obligations. The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities: Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active. Level 3: Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability. The following table presents information about the Company’s assets that are measured at fair value on a recurring basis at December 31, 2019 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value: Description Level December 31, Assets: Marketable securities held in Trust Account – U.S. Treasury Securities Money Market Fund 1 $ 224,015,369 The gross holding losses and fair value of held-to-maturity securities at December 31, 2018 are as follows: Held-To-Maturity Amortized Gross Fair December 31, 2018 U.S. Treasury Securities (Mature on 4/11/2019) $ 110,548,511 $ (11,025 ) $ 110,537,486 December 31, 2018 U.S. Treasury Securities (Mature on 4/4/2019) $ 110,585,340 $ (6,208 ) $ 110,579,132

SUBSEQUENT EVENTS The Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the financial statements were issued. Other than as described below, the Company did not identify subsequent events that would have required adjustment or disclosure in the financial statements. On February 27, 2020, the Company amended its underwriting agreement with Cantor pursuant to which Cantor agreed to forfeit 75% of the aggregate $7,700,000 deferred fee, or $5,775,000, that would otherwise be payable to them upon the consummation of a Business Combination. The forfeiture of the deferred fee will only apply in the event that the Company consummates the Business Combination with Grid Dynamic. On February 27, 2020, the Company entered into a capital markets advisory agreement (the “Capital Market Advisory Agreement”) with Cantor pursuant to which the Company engaged Cantor to act as a capital markets advisor in connection with the Company’s proposed Business Combination with Grid Dynamics. The Company has agreed to pay Cantor a cash fee of $4,525,000, of which the Company may reduce the fee by up to $455,000, solely to the extent such amount is paid to Northland Securities Inc. and Benchmark Investments Inc. The fee is payable to Cantor upon the consummation of the Business Combination with Grid Dynamics.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.
Use of Estimates	Use of Estimates The preparation of consolidated 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 and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future events. Accordingly, the actual results could differ significantly from the Company’s estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of December 31, 2019 and 2018.
Common Stock Subject to Possible Redemption	Common Stock Subject to Possible Redemption The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock, sold in the Public Offering, features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. The shares of common stock sold in the private placements do not contain these rights. Accordingly, at December 31, 2019 and 2018, 20,589,710 and 20,921,905 shares of common stock subject to possible redemption, respectively, are presented as temporary equity, outside of the stockholders’ equity section of the Company’s consolidated balance sheets.
Offering Costs	Offering Costs Offering costs consist of legal, accounting, underwriting fees and other costs incurred through the balance sheet date that are directly related to the Initial Public Offering. Offering costs amounting to $12,821,311 were charged to stockholders’ equity upon the completion of the Initial Public Offering.
Income Taxes	Income Taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2019 and 2018. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.
Net Income (Loss) Per Common Share	Net Income (Loss) Per Common Share Net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. The Company has not considered the effect of warrants sold in the Initial Public Offering and private placement to purchase 11,320,000 shares of Class A common stock in the calculation of diluted income (loss) per share, since the exercise of the warrants are contingent upon the occurrence of future events and the inclusion of such warrants would be anti-dilutive. The Company’s statement of operations includes a presentation of income (loss) per share for common shares subject to redemption in a manner similar to the two-class method of income per share. Net income per common share, basic and diluted for Class A redeemable common stock is calculated by dividing the interest income earned on the Trust Account (net of applicable franchise and income taxes of approximately $1,493,000 and $341,000 for the year ended December 31, 2019 and for the period from May 21, 2018 (inception) through December 31, 2018, respectively), by the weighted average number of Class A redeemable common stock outstanding during the period. Net loss per common share, basic and diluted for Class A and Class B non-redeemable common stock is calculated by dividing the net income (loss), less income attributable to Class A redeemable common stock, by the weighted average number of Class A and Class B non-redeemable common stock outstanding for the period. Class A and Class B non-redeemable common stock includes the Founder Shares and the Placement Units as these shares do not have any redemption features and do not participate in the income earned on the Trust Account. The following table reflects the calculation of basic and diluted net income (loss) per common share: Year Ended December 31, 2019 For the Period from May 21, 2018 (inception) Through December 31, 2018 Redeemable Common Stock Numerator: Earnings allocable to Redeemable Common Stock Interest Income $ 4,664,912 $ 1,158,467 Income and Franchise Tax $ (1,493,035 ) $ (340,715 ) Net Earnings $ 3,171,877 $ 817,752 Denominator: Weighted Average Redeemable Common Stock Redeemable Common Stock, Basic and Diluted 22,000,000 21,654,321 Earnings/Basic and Diluted Redeemable Common Stock $ 0.14 $ 0.04 Non-Redeemable Common Stock Numerator: Net Loss minus Redeemable Net Earnings Net (Loss) Income $ (3,321,949 ) $ 615,364 Redeemable Net Earnings $ (3,171,877 ) $ (817,752 ) Non-Redeemable Net Loss $ (6,493,826 ) $ (202,388 ) Denominator: Weighted Average Non-Redeemable Common Stock Non-Redeemable Common Stock, Basic and Diluted (1) 6,140,000 5,733,422 Loss/Basic and Diluted Non-Redeemable Common Stock $ (1.06 ) $ (0.04 ) Note: As of December 31, 2019 and 2018, basic and diluted shares are the same as there are no securities that are dilutive to the Company’s common stockholders.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times may exceed the Federal Depository Insurance Coverage of $250,000. At December 31, 2019 and 2018, the Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.
Financial Instruments	Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the accompanying consolidated balance sheets, primarily due to their short-term nature.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s consolidated financial statements.

Registration rights, description	Notwithstanding the foregoing, the underwriters may not exercise their demand and “piggyback” registration rights after five (5) and seven (7) years after the effective date of the registration statement and may not exercise their demand rights on more than one occasion. The Company will bear the expenses incurred in connection with the filing of any such registration statements.
Underwriting commitments, description	The Company granted the underwriters a 45-day option to purchase up to 3,000,000 additional Units to cover over-allotments at the Initial Public Offering price less the underwriting discounts and commissions. On October 25, 2018, the underwriters elected to partially exercise their over-allotment option to purchase 2,000,000 Units at a purchase price of $10.00 per Unit. In connection with the closing of the Initial Public Offering and the over-allotment option, the underwriters were paid a cash underwriting discount $4,400,000. In addition, the underwriters are entitled to a deferred fee of $0.35 per Unit, or $7,700,000 in the aggregate. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement. Merger Agreement On November 13, 2019, the Company, Merger Sub 1 and Merger Sub 2 (collectively, the “ChaSerg Parties”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Grid Dynamics and Automated Systems Holdings Limited (“ASL”), a company incorporated in Bermuda with limited liability, solely in its capacity as representative of the stockholders of Grid Dynamics immediately prior to the consummation of the business combination. Pursuant to the Merger Agreement, (i) Merger Sub 1 will be merged with and into Grid Dynamics, with Grid Dynamics surviving the merger on the terms and subject to the conditions set forth in the Merger Agreement (the “Initial Merger”), and (ii) as part of the same overall transaction, immediately following the Initial Merger, Grid Dynamics will be merged with and into Merger Sub 2, with Merger Sub 2 surviving on the terms and subject to the conditions set forth in the Merger Agreement (the “Second Step Merger” and, together with the Initial Merger, the “Mergers”). The purchase price will be paid to Grid Dynamics stockholders as of immediately prior to the consummation of the Business Combination in a combination of stock and cash consideration. The aggregate merger consideration (the “Merger Consideration”) to be paid pursuant to the Merger Agreement will be an amount equal to: (i) $130,000,000, subject to certain reductions (the “Cash Consideration”) and (ii) 25,523,810 shares of the Company’s Class A Common Stock (the “Share Consideration”). The Cash Consideration is subject to reduction in an amount equal to: $13,500,000 multiplied by (x) the balance of the trust account (the “Trust Account”) established by the Company for the benefit of its public stockholders as at the date of the signing of the Merger Agreement minus the Available Parent Cash, divided by (y) 30% of the Trust Account balance as at the date of the signing of the Merger Agreement, where such adjustment amount can be no more than $13,500,000 and no less than $0, and is offset by an equivalent increase in the Share Consideration. The Share Consideration is subject to customary adjustment at closing by an amount of shares of the Company’s Class A Common Stock to account for changes in working capital, indebtedness and excess cash. Excess cash also includes an adjustment mechanism for funds that are used between signing and closing for specified acquisitions. The Share Consideration is also subject to adjustment for earnings before income taxes, depreciation and amortization (“EBITDA”) performance targets, whereby the Share Consideration is reduced by $1,500,000 for every $100,000 by which the estimated total EBITDA in 2019 is below $23,800,000. The post-closing adjustment of the Share Consideration is capped at 857,143 shares of the Company’s Class A Common Stock which will be placed in escrow at closing. The obligations of the parties to consummate the Merger are subject to various conditions, including, among other things: (i) the approval of Grid Dynamics’s stockholders; (ii) the approval of the Company’s stockholders at a special meeting of the Company’s stockholders; (iii) the approval of the shareholders of ASL, including Teamsun Technology (HK) Limited (“Teamsun HK”), a company listed on the Stock Exchange of Hong Kong Limited (“HKEX”); (iv) the approval of the shareholders of Beijing Teamsun Technology Co. Ltd.
