Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Organization and Business Operations	1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS Modern Media Acquisition Corp. (the “Company,” “we,” “us” or “our”) was initially formed as a Delaware limited liability company on June 9, 2014 under the name of M Acquisition Company I LLC. On January 3, 2017, the Company converted from a limited liability company to a Delaware C Corporation and changed its name to Modern Media Acquisition Corp. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, recapitalization or similar business combination with one or more businesses that the Company has not yet identified (a “Business Combination”). The Company has neither engaged in any operations nor generated significant revenue to date. All activity through September 30, 2017 relates to the Company’s formation, its initial public offering (“Initial Public Offering”), which is described below, and its search for a Business Combination. The registration statement for the Company’s Initial Public Offering was declared effective on May 11, 2017. On May 17, 2017 (the “Closing Date”), the Company completed its Initial Public Offering of 20,700,000 units (“Units” and, with respect to the common stock included in the Units offered, the “Public Shares”), which included the full exercise by the underwriters of their over-allotment option in the amount of 2,700,000 Units at $10.00 per Unit, generating gross proceeds of $207,000,000. The Units are described in Note 3. On May 11, 2017, the Company declared and paid to its stockholders a stock dividend (the “Stock Dividend”) of approximately 0.20475 shares for each share then held. As a result thereof, the total number of Founder Shares (as defined in Note 5) outstanding increased from 4,312,500 to 5,175,000. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 7,320,000 warrants (the “Private Placement Warrants”) at a price of $1.00 per warrant in a private placement to the Company’s sponsor, Modern Media Sponsor LLC (the “Sponsor”), generating gross proceeds of $7,320,000, which is described in Note 4. Transaction costs amounted to $12,309,271, consisting of $3,600,000 of underwriting fees, $7,785,000 of deferred underwriting fees payable (which are held in the Trust Account (as defined below)) and $924,271 of other costs. Following the closing of the Initial Public Offering, $209,070,000 ($10.10 per Unit) of the net proceeds from the sale of the Units and the Private Placement Warrants was placed in a trust account (the “Trust Account”) and has been 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 an open-ended investment company that holds itself out as a money market fund meeting certain conditions under Rule 2a-7 The Company’s management has broad discretion with respect to the specific application of the net proceeds from the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward completing a Business Combination. Nasdaq Capital Market (“NASDAQ”) rules provide that the Company’s initial Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (excluding any deferred underwriting commissions and taxes payable on interest earned on the funds held in the Trust Account) at the time of signing a definitive agreement in connection with a Business Combination. However, the Company will only complete a Business Combination if the post-Business Combination 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. There is no assurance that the Company will be able to successfully effect a Business Combination. The Company will provide its 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. Except as discussed below, the stockholders will be entitled to redeem their Public Shares at a per-share per-share The Initial Stockholders have agreed to waive their redemption rights with respect to their Founder Shares and any Public Shares they may acquire (i) in connection with the completion of a Business Combination, (ii) in connection with a stockholder vote to amend the Company’s Second Amended and Restated Certificate of Incorporation to modify the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if it does not complete a Business Combination within the Combination Period (as defined below), and (with respect to their Founder Shares only), (iii) if the Company fails to complete a Business Combination within the Combination Period and (iv) upon the Company’s liquidation (although the Initial Stockholders will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares they hold if the Company fails to complete a Business Combination within the Combination Period). Notwithstanding the foregoing redemption rights, if the Company seeks stockholder approval of its Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Second 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 Exchange Act), will be restricted from redeeming its Public Shares with respect to an aggregate of 20.0% or more of the shares sold in the Initial Public Offering without the Company’s consent. However, there will be no restriction on the Company’s stockholders’ ability to vote all of their Public Shares for or against a Business Combination. The Company has 18 months from the Closing Date to complete a Business Combination (or 21 months from the Closing Date if the Company has executed a letter of intent, agreement in principle or definitive agreement for a Business Combination within 18 months from the Closing Date but has not completed a Business Combination within such 18 month period (the “Combination Period”)). If the Company is unable to complete a Business Combination within 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, and subject to having lawfully available funds therefor, redeem the Public Shares, at a per-share The underwriters have agreed to waive their rights to their deferred underwriting commission held in the Trust Account in the event the Company does not complete a Business Combination during the Combination Period and, in such event, such amounts will be included with the 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 (including Trust Account assets) will be only $10.10 per share. In order to protect the amounts held in the Trust Account, the Company has entered into an agreement with the Sponsor (the “Indemnifier”), pursuant to which the Indemnifier has agreed to be liable to the Company if and to the extent any claims by a vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a Business Combination, reduce the amount of funds in the Trust Account below a specified threshold. This liability does 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 its Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933 (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Indemnifier 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 Indemnifier will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, 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.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The accompanying unaudited condensed financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q S-X The accompanying unaudited financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K 10-K 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 auditor 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 Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and 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 periods. 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 confirming events. Accordingly, the actual results could differ significantly from those 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 September 30, 2017 or March 31, 2017. Cash and marketable securities held in Trust Account At September 30, 2017, the assets held in the Trust Account were held in cash and marketable securities. 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 (if any) 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 features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at September 30, 2017, 19,510,075 shares of common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet. Offering costs Offering costs consist principally of legal, accounting, underwriting fees and other costs incurred that are directly related to the Initial Public Offering. Offering costs of $12,309,271 were charged to stockholders’ equity upon the completion of the Initial Public Offering. Income taxes Prior to January 3, 2017, the Company was a limited liability company and taxed as a partnership; the income or loss was required to be reported by each respective member on their separate income tax returns. Therefore, no provision for income taxes has been provided in the accompanying financial statements for periods prior to January 3, 2017. Effective January 3, 2017, the Company converted to a C Corporation. Had the Company been subject to federal and state income taxes for the six months ended September 30, 2016, the Company determined that the provision for income taxes would have been insignificant due to the Company’s immaterial net loss for the period presented in the statements of operations, and, accordingly, the Company did not present pro forma income tax disclosures in the accompanying statements of operations for this period to illustrate what the Company’s net loss would have been had the income taxes been provided for as though the Company were subject to taxes as a C Corporation. The Company complies with the accounting and reporting requirements of ASC Topic 740 “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Deferred tax assets were deemed to be immaterial as of September 30, 2017 and March 31, 2017. ASC Topic 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 The Company may be subject to potential examination by federal, state and city taxing authorities in the area of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with federal, state and city tax laws. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Net income (loss) per common share The Company complies with accounting and disclosure requirements of ASC Topic 260, “Earnings Per 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. Shares of common stock subject to possible redemption at September 30, 2017 have been excluded from the calculation of basic income (loss) per share since such shares, if redeemed, only participate in their pro rata share of the Trust Account earnings. The Company has not considered the effect of (1) warrants sold in the Initial Public Offering and private placement to purchase 17,670,000 shares of common stock and (2) rights sold in the Initial Public Offering that are convertible into 2,070,000 shares of common stock, in the calculation of diluted income (loss) per share, since the exercise of the warrants and the conversion of the rights into shares of common stock is contingent upon the occurrence of future events. Diluted net income per share for the three and six months ended September 30, 2017 includes the impact of 25,875,000 and 20,643,132 shares of common stock, respectively. 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 September 30, 2017 and March 31, 2017, the Company had not experienced losses on this account, and management believes the Company is not exposed to significant risks on such account. Fair value of 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 balance sheets, primarily due to their short-term nature. Recently issued accounting standards 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 financial statements.

Private Placement	4. PRIVATE PLACEMENT Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased 7,320,000 Private Placement Warrants at $1.00 per warrant (for an aggregate purchase price of $7,320,000). Each Private Placement Warrant is exercisable to purchase one share of the Company’s common stock at $11.50 per share. The proceeds from the Private Placement Warrants were added to the proceeds from the Initial Public Offering held in the Trust Account. There are no redemption rights or liquidating distributions from the Trust Account with respect to the Private Placement Warrants. If the Company does not complete a Business Combination within the Combination Period, the proceeds of the sale of the Private Placement Warrants will be used to fund the required redemption of the Company’s Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless.

Related Party Transactions [Abstract]
Related Party Transactions	5. RELATED PARTY TRANSACTIONS Founder Shares In June 2014, the Company was formed by MIHI LLC (“MIHI”), at which point MIHI paid an aggregate purchase price of $25,000, or approximately $250.00 per share, for its ownership interest in the Company. Prior to this initial investment, the Company had no assets, tangible or intangible. In January 2017, MIHI transferred its ownership interest in the Company, consisting of 100 shares of the Company’s common stock, to the Sponsor for no consideration. The per share price for the common stock was determined by dividing the amount initially contributed to the Company by the number of common stock issued. On February 15, 2017, the Company completed a 71,875 to one stock split (the “Stock Split”) of its common stock and, as a result, 7,187,500 shares of the Company’s common stock were outstanding (the “Founder Shares”). The Sponsor subsequently sold certain of such shares to certain of the Company’s officers and/or directors, and thereafter, the Sponsor surrendered 2,875,000 Founder Shares to the Company for no consideration. On May 11, 2017, the Company declared and paid to its stockholders the Stock Dividend of approximately 0.20475 shares for each share then held. All of the stockholders other than the Sponsor surrendered to the Company for no consideration the shares of common stock received by them in the Stock Dividend. As a result thereof, the total number of Founder Shares outstanding increased from 4,312,500 to 5,175,000 and the number of Founder Shares held by the Sponsor increased from 4,212,500 to 5,075,000. The holders of the Founder Shares have agreed not to transfer, assign or sell any of their Founder Shares (except to certain permitted transferees) until the earlier of one year after the completion of a Business Combination or earlier if, subsequent to a Business Combination, (i) the last reported closing price of the common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading “Lock-Up Promissory Note — Related Party As of March 31, 2017, the Company’s Sponsor had committed to provide loans to the Company of up to $650,000 for expenses related to the Company’s formation and the Initial Public Offering. The loans were non-interest Related Party Loans In order to finance potential transaction costs in connection with a Business Combination, (i) the Sponsor has committed to loan the Company up to an aggregate of $500,000 in the event that funds held outside of the Trust Account are insufficient to fund expenses relating to investigating and selecting a target business and other working capital requirements after the Initial Public Offering and prior to a Business Combination and (ii) the Sponsor, an affiliate of the Sponsor or certain of the Company’s officers and directors may, but are not obligated to, loan the Company any additional funds as may be required (“Working Capital Loans”), which will be repaid only upon the completion of a Business Combination. If the Company does not complete a Business Combination, the Company may use a portion of any funds held outside the Trust Account to repay the Working Capital Loans; however, no proceeds from the Trust Account may be used for such repayment. Up to $1,000,000 of such Working Capital Loans may be convertible into warrants of the post-Business Combination entity at a price of $1.00 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants with respect to exercise price, exercisability and exercise period, except as provided in the Company’s registration statement filed in connection with the Initial Public Offering. There were no Working Capital Loans outstanding as of September 30, 2017 or March 31, 2017.

COMMITMENTS AND CONTINGENCIES Registration Rights Pursuant to a registration rights agreement entered into on the Closing Date, the holders of the Founder Shares and Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans, if any, and their respective permitted transferees (and any shares of common stock issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans, if any) are entitled to registration rights. The holders of these securities are entitled to make up to three demands, in the case of the Founder Shares and the Private Placement Warrants (and any shares of common stock issuable upon the exercise of the Private Placement Warrants), excluding short form demands, and one demand, in the case of the warrants that may be issued upon the conversion of Working Capital Loans (and any shares of common stock issuable upon the exercise of such warrants), that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to other registration statements filed by the Company and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the registration rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of any applicable lock-up Deferred Underwriting Commission The underwriters were paid a cash underwriting discount of $0.20 per Unit, or $3,600,000 in the aggregate, upon the closing of the Initial Public Offering. In addition, the underwriters are entitled to a deferred fee of $0.38 per Unit, or $7,785,000 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. Right of First Refusal The Company granted Macquarie Capital (USA) Inc., an affiliate of the Sponsor and an underwriter of the Initial Public Offering, a right of first refusal for a period of 36 months from the closing date of the Initial Public Offering to provide to the Company certain financial advisory, underwriting, capital raising, and other services for which they may receive fees. The actual amount of fees to be paid will vary significantly based on the size of any transaction and the extent to which other investments banks are involved. Deferred Legal Fees The Company is obligated to pay deferred legal fees of $300,000 upon the consummation of a Business Combination for services performed in connection with the Initial Public Offering. If no Business Combination is consummated, the Company will not be obligated to pay such fee.

Further, there are no contractual penalties for failure to deliver securities to the holders of the Public Rights upon consummation of a Business Combination. Additionally, in no event will the Company be required to net cash settle the Public Rights. Accordingly, the Public Rights may expire worthless.

Furthermore, the Private Placement Warrants will expire five years after the completion of a Business Combination or earlier upon the Company’s liquidation. Additionally, the Private Placement Warrants are non-redeemable The Company may redeem the Public Warrants (the “30-day • in whole and not in part; • at a price of $0.01 per warrant; • upon a minimum of 30 days’ prior written notice of redemption; • if, and only if, the last reported closing price of the Company’s common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading • if, and only if, there is an effective registration statement in effect with respect to the shares of common stock underlying such warrants at the time of redemption and a current prospectus relating to those shares of common stock is available throughout the 30-day 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 is described in the warrant agreement. The exercise price and number of shares of common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuance of common stock at a price below their 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.

Fair Value Measurements	8. FAIR VALUE MEASUREMENTS The Company follows the guidance in ASC 820 for its financial assets and liabilities that are re-measured non-financial re-measured 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 September 30, 2017 and March 31, 2017, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value: Description Level September 30, March 31, Assets: Cash and marketable securities held in Trust Account 1 $ 209,550,060 $ —

Summary of Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accompanying unaudited condensed financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q S-X The accompanying unaudited financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K 10-K
Emerging growth company	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 auditor 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
Use of estimates	Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and 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 periods. 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 confirming events. Accordingly, the actual results could differ significantly from those 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 September 30, 2017 or March 31, 2017.
Cash and marketable securities held in Trust Account	Cash and marketable securities held in Trust Account At September 30, 2017, the assets held in the Trust Account were held in cash and marketable securities.
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 (if any) 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 features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at September 30, 2017, 19,510,075 shares of common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet.
Offering costs	Offering costs Offering costs consist principally of legal, accounting, underwriting fees and other costs incurred that are directly related to the Initial Public Offering. Offering costs of $12,309,271 were charged to stockholders’ equity upon the completion of the Initial Public Offering.
Income taxes	Income taxes Prior to January 3, 2017, the Company was a limited liability company and taxed as a partnership; the income or loss was required to be reported by each respective member on their separate income tax returns. Therefore, no provision for income taxes has been provided in the accompanying financial statements for periods prior to January 3, 2017. Effective January 3, 2017, the Company converted to a C Corporation. Had the Company been subject to federal and state income taxes for the six months ended September 30, 2016, the Company determined that the provision for income taxes would have been insignificant due to the Company’s immaterial net loss for the period presented in the statements of operations, and, accordingly, the Company did not present pro forma income tax disclosures in the accompanying statements of operations for this period to illustrate what the Company’s net loss would have been had the income taxes been provided for as though the Company were subject to taxes as a C Corporation. The Company complies with the accounting and reporting requirements of ASC Topic 740 “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Deferred tax assets were deemed to be immaterial as of September 30, 2017 and March 31, 2017. ASC Topic 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 The Company may be subject to potential examination by federal, state and city taxing authorities in the area of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with federal, state and city tax laws. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.
Net income (loss) per common share	Net income (loss) per common share The Company complies with accounting and disclosure requirements of ASC Topic 260, “Earnings Per 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. Shares of common stock subject to possible redemption at September 30, 2017 have been excluded from the calculation of basic income (loss) per share since such shares, if redeemed, only participate in their pro rata share of the Trust Account earnings. The Company has not considered the effect of (1) warrants sold in the Initial Public Offering and private placement to purchase 17,670,000 shares of common stock and (2) rights sold in the Initial Public Offering that are convertible into 2,070,000 shares of common stock, in the calculation of diluted income (loss) per share, since the exercise of the warrants and the conversion of the rights into shares of common stock is contingent upon the occurrence of future events. Diluted net income per share for the three and six months ended September 30, 2017 includes the impact of 25,875,000 and 20,643,132 shares of common stock, respectively.
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 September 30, 2017 and March 31, 2017, the Company had not experienced losses on this account, and management believes the Company is not exposed to significant risks on such account.
Fair value of financial instruments	Fair value of 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 balance sheets, primarily due to their short-term nature.
Recently issued accounting standards	Recently issued accounting standards 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 financial statements.
