Description of Organization and Business Operations [Abstract]
Description of Organization and Business Operations	Note 1. Description of Organization and Business Operations Organization and General Vantage Energy Acquisition Corp. (the “ Company Initial Business Combination Securities Act JOBS Act At March 31, 2018, the Company had not commenced any operations. All activity for the period from February 8, 2017 (date of inception) through March 31, 2018 relates to the Company’s formation and the initial public offering (the “ Public Offering Units Private Placement Warrants Sponsor Overallotment Units The Company will not generate any operating revenues until after completion of its Initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on cash and cash equivalents from the net proceeds from the Public Offering. The fiscal year of the Company is the twelve-month calendar period from January 1 through December 31. The Company intends to finance its Initial Business Combination with proceeds from the Public Offering (Note 3) and the private placements of the Private Placement Warrants (Note 4) and forward purchase securities described in Note 4, the Company’s capital stock, debt or a combination of the foregoing. Upon the closings of the Public Offering, the sale of the Overallotment Units and the private placements of the Private Placement Warrants, approximately $552,000,000 was placed in a trust account (the “ Trust Account The registration statement for the Company’s Public Offering (as described in Note 3) was declared effective by the U.S. Securities and Exchange Commission (the “ SEC Trust Account The proceeds held in the Trust Account will be invested only in U.S. government securities with a maturity of one hundred eighty (180) days or less or in money market funds that meet certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended, and that invest only in direct U.S. government treasury obligations, as determined by the Company. Funds will remain in the Trust Account until the earlier of (i) the consummation of the Initial Business Combination or (ii) the distribution of the Trust Account proceeds as described below. The remaining proceeds outside the Trust Account may be used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses. The Company’s amended and restated certificate of incorporation provides that, other than the withdrawal of interest to pay franchise and income taxes, none of the funds held in the Trust Account will be released until the earliest of: (i) the completion of the Initial Business Combination; (ii) the redemption of any shares of Class A common stock included in the Units (the “ Public Shares Initial Business Combination The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Public Offering, although substantially all of the net proceeds of the Public Offering are intended to be generally applied toward consummating an Initial Business Combination. The Initial Business Combination must occur with one or more target businesses that together have a fair market value of at least 80% of the assets held in the Trust Account (excluding the deferred underwriting discounts and commissions and taxes payable on interest earned on the Trust Account) at the time of the agreement to enter into the Initial Business Combination. Furthermore, there is no assurance that the Company will be able to successfully effect an Initial Business Combination. The Company, after signing a definitive agreement for an Initial Business Combination, will either (i) seek stockholder approval of the Initial Business Combination at a meeting called for such purpose in connection with which stockholders may seek to redeem their Public Shares, regardless of whether they vote for or against the Initial Business Combination, for cash equal to their pro rata share of the aggregate amount on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest not previously released to the Company to pay its franchise and income taxes, or (ii) provide stockholders with the opportunity to sell their Public Shares to the Company by means of a tender offer (and thereby avoid the need for a stockholder vote) for an amount in cash equal to their pro rata share of the aggregate amount on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest not previously released to the Company to pay its franchise and income taxes. The decision as to whether the Company will seek stockholder approval of the Initial Business Combination or will allow stockholders to sell their Public Shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek stockholder approval, unless a vote is required by law or under NASDAQ rules. If the Company seeks stockholder approval, it will complete its Initial Business Combination only if a majority of the outstanding shares of common stock voted are voted in favor of the Initial Business Combination. However, in no event will the Company redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001. In such case, the Company would not proceed with the redemption of its Public Shares and the related Initial Business Combination, and instead may search for an alternate Initial Business Combination. If the Company holds a stockholder vote or there is a tender offer for shares in connection with an Initial Business Combination, a stockholder will have the right to redeem his, her or its Public Shares for an amount in cash equal to his, her or its pro rata share of the aggregate amount on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest not previously released to the Company to pay its franchise and income taxes. As a result, such Public Shares are recorded at redemption amount and classified as temporary equity upon the completion of the Public Offering, in accordance with the Financial Accounting Standards Board (“ FASB ASC Distinguishing Liabilities from Equity Pursuant to the Company’s amended and restated certificate of incorporation, if the Company is unable to complete the Initial Business Combination within 24 months from the closing of the Public Offering, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter subject to lawfully available funds therefor, 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 the Company’s franchise and income taxes (less up to $100,000 of such net 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. The Sponsor and the Company’s officers and directors have entered into a letter agreement with the Company, pursuant to which they have agreed to waive their rights to liquidating distributions from the Trust Account with respect to any Founder Shares (as defined below) held by them if the Company fails to complete the Initial Business Combination within 24 months of the closing of the Public Offering. However, if the Sponsor or any of the Company’s directors, officers or affiliates acquire shares of Class A common stock in or after the Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such shares if the Company fails to complete the Initial Business Combination within the prescribed time period. In the event of a liquidation, dissolution or winding up of the Company after an Initial Business Combination, the Company’s stockholders are entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class of stock, if any, having preference over the common stock. The Company’s stockholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the common stock, except that the Company will provide its stockholders with the opportunity to redeem their Public Shares for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account, upon the completion of the Initial Business Combination, subject to the limitations described herein. Liquidation and Going Concern: The Company only has 24 months from the closing date of the Public Offering (until April 17, 2019) to complete an Initial Business Combination. If the Company does not complete an Initial Business Combination within 24 months from the closing date of the Public Offering, 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 the Company’s franchise and income taxes (less up to $100,000 of such net 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 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. The Sponsor and the Company’s officers and directors have entered into a letter agreement with the Company, pursuant to which they have agreed to waive their rights to liquidating distributions from the Trust Account with respect to any Founder Shares (as defined below) held by them if the Company fails to complete the Initial Business Combination within 24 months of the closing of the Public Offering. However, if the Sponsor or any of the Company’s directors, officers or affiliates acquire shares of Class A common stock in or after the Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such shares if the Company fails to complete the Initial Business Combination within the prescribed time period. In the event of liquidation, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be less than the initial public offering price per Unit in the Public Offering. This 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 17, 2019. As of March 31, 2018, the Company may not have sufficient liquidity to meet its future obligations. Management has determined that the Company has access to funds from the Sponsor entity that are sufficient to fund the working capital needs of the Company until the Initial Business Combination or April 17, 2019.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited interim condensed financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“ GAAP The accompanying unaudited interim condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Form 10-K filed by the Company with the SEC on March 27, 2018. Emerging Growth Company 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 Securities Exchange Act of 1934, as amended) 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. Net Income (Loss) Per Share of Common Stock Net income (loss) per share of common stock is computed by dividing net income attributable to common shares by the weighted average number of shares of common stock outstanding during the period, plus, to the extent dilutive, the incremental number of shares of common stock to settle warrants, as calculated using the treasury stock method. An aggregate of 53,170,956 shares of Class A common stock subject to possible redemption at March 31, 2018 have been excluded from the calculation of basic net income per share of common stock since such shares, if redeemed, only participate in their pro rata share of the trust earnings. The Company has not considered the effect of the warrants sold in the Public Offering (including the consummation of the overallotment) and private placements of the Private Placement Warrants to purchase an aggregate of 27,093,333 shares of the Company’s Class A common stock in the calculation of diluted net income per share of common stock, since their inclusion would be anti-dilutive under the treasury stock method. At March 31, 2017, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company under the treasury stock method. As a result, diluted loss per common share is the same as basic loss per common share for the period. 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. Cash and Marketable Securities held in Trust Account The amounts held in the Trust Account represent net proceeds from the Public Offering and the private placements of Private Placement Warrants of $552,000,000 which were invested in a money market instrument that invests in U.S. Treasury Securities with original maturities of six months or less and are classified as restricted assets because such amounts can only be used by the Company in connection with the consummation of an Initial Business Combination. As of March 31, 2018, cash and marketable securities held in the Trust Account had a fair value of $242,807 and $555,849,755, respectively. At March 31, 2018, there was $4,092,562 of investment income held in the Trust Account available to be released to the Company to pay franchise and income taxes. As of December 31, 2017, cash and marketable securities held in the Trust Account had a fair value of $9,435 and $554,380,922, respectively. At December 31, 2017, there was $2,390,357 of investment income held in the Trust Account available to be released to the Company to pay franchise and income taxes. Redeemable Common Stock As discussed in Note 1, all of the 55,200,000 Public Shares contain a redemption feature which allows for the redemption of Class A common stock under the Company’s liquidation or tender offer/stockholder approval provisions. In accordance with FASB ASC 480, redemption provisions not solely within the control of the Company require the security to be classified outside of permanent equity. Ordinary liquidation events, which involve the redemption and liquidation of all of the entity’s equity instruments, are excluded from the provisions of FASB ASC 480. Although the Company has not specified a maximum redemption threshold, its amended and restated certificate of incorporation provides that in no event will the Company redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001. The Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of the security at the end of each reporting period. Increases or decreases in the carrying amount of redeemable shares of Class A common stock shall be affected by charges against additional paid-in capital. At March 31, 2018, 53,170,956 of the 55,200,000 Public Shares were classified outside of permanent equity. At December 31, 2017, 53,046,079 of the 55,200,000 Public Shares were classified outside of permanent equity. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of cash accounts in a financial institution which, at times, may exceed the Federal depository insurance coverage of $250,000. The Company has not experienced losses on these accounts, and management believes the Company is not exposed to significant risks on such accounts. Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC 820, “ Fair Value Measurements and Disclosures Use of Estimates The preparation of the financial statements in conformity with GAAP requires the Company’s 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 expenses during the reporting period. Actual results could differ from those estimates. Income Taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC 740, “ Income Taxes FASB 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. There were no unrecognized tax benefits as of March 31, 2018 or December 31, 2017. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties at March 31, 2018 or December 31, 2017. 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. The Company may be subject to potential examination by federal, state, and city taxing authorities in the areas 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. Related Parties The Company follows subtopic ASC 850-10 for the identification of related parties and disclosure of related party transactions. Pursuant to Section 850-10-20, the related parties include: (a) affiliates of the Company (“Affiliate” means, with respect to any specified person, any other person that, directly or indirectly through one or more intermediaries, controls, is controlled by or is under common control with such person, as such terms are used in and construed under Rule 405 under the Securities Act); (b) entities for which investments in their equity securities would be required, absent the election of the fair value option under the Fair Value Option Subsection of Section 825-10-15, to be accounted for by the equity method by the investing entity; (c) trusts for the benefit of employees, such as pension and profit-sharing trusts that are managed by or under the trusteeship of management; (d) principal owners of the Company; (e) management of the Company; (f) other parties with which the Company may deal if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests; and (g) other parties that can significantly influence the management or operating policies of the transacting parties or that have an ownership interest in one of the transacting parties and can significantly influence the other to an extent that one or more of the transacting parties might be prevented from fully pursuing its own separate interests. Subsequent Events The Company evaluates subsequent events and transactions that occur after the balance sheet date for potential recognition or disclosure. Any material events that occur between the balance sheet date and the date that the financial statements were issued are disclosed as subsequent events, while the financial statements are adjusted to reflect any conditions that existed at the balance sheet date. Recent Accounting Pronouncements The Company’s management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have an effect on the Company’s financial statements.

Public Offering	Note 3. Public Offering In April 2017, the Company closed its Public Offering of 55,200,000 Units at a price of $10.00 per Unit, with gross proceeds of $552,000,000 from the sale of Units. The closings occurred on April 17, 2017 with respect to 48,000,000 Units and on April 19, 2017 with respect to 7,200,000 Units related to the exercise of the underwriters’ overallotment option. Each Unit consists of one share of the Company’s Class A common stock, $0.0001 par value per share, and one-third of one warrant (each, a “ Warrant Warrants Simultaneous with the closing of the Public Offering on April 17, 2017, the Sponsor purchased an aggregate of 7,733,333 Private Placement Warrants at a price of $1.50 per whole warrant (approximately $11,600,000 in the aggregate) in a private placement. Simultaneously with the closing of the overallotment, the Company consummated the private placement of an additional 960,000 Private Placement Warrants to the Sponsor, generating gross proceeds of approximately $1,440,000. The Company paid underwriting discounts and commissions of 2.0% of the per Unit offering price to the underwriters at the closing of the Public Offering, with an additional fee (the “ Deferred Discount

Related Party Transactions [Abstract]
Related Party Transactions	Note 4. Related Party Transactions Founder Shares In February 2017, the Sponsor purchased 11,500,000 shares of the Company’s Class B common stock (the “ Founder Shares The Founder Shares are identical to the Public Shares except that the Founder Shares are shares of the Company’s Class B common stock which automatically convert into shares of the Company’s Class A common stock at the time of the Company’s Initial Business Combination and are subject to certain transfer restrictions, as described in more detail below. In April 2017, the Company effected a stock dividend of 2,300,000 shares of the Company’s Class B common stock, resulting in the Sponsor holding an aggregate of 13,800,000 Founder Shares. On April 10, 2017, the Sponsor transferred an aggregate of 80,000 Founder Shares to the Company’s independent directors at their original purchase price. In connection with the Public Offering, the holders of the Founder Shares agreed to forfeit up to 1,800,000 Founder Shares to the extent that the overallotment option in connection with the Public Offering was not exercised in full by the underwriters so that the holders of the Founder Shares would own 20.0% of the Company’s issued and outstanding shares of common stock after the Public Offering. As described above, the underwriters exercised their overallotment option in connection with the Public Offering in full, and therefore none of the Founder Shares were forfeited. The holders of the Founder Shares agreed, subject to limited exceptions, not to transfer, assign or sell any of their Founder Shares until the earlier to occur of: (A) one year after the completion of the Initial Business Combination or (B) subsequent to the Initial Business Combination, (x) if the last sale price of the Company’s 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 the Initial Business Combination, or (y) the date on which the Company completes a liquidation, merger, 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. Private Placement Warrants Upon the closing of the Public Offering on April 17, 2017 and April 19, 2017, the Sponsor purchased an aggregate of 8,693,333 Private Placement Warrants at a price of $1.50 per whole warrant (approximately $13,040,000 in the aggregate) in a private placement that occurred simultaneously with the closing of the Public Offering. Each whole Private Placement Warrant is exercisable for one whole share of the Company’s Class A common stock at a price of $11.50 per share. A portion of the purchase price of the Private Placement Warrants was added to the proceeds from the Public Offering held in the Trust Account. If the Initial Business Combination is not completed within 24 months from the closing of the Public Offering, the proceeds from the sale of the Private Placement Warrants held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law), and the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable and exercisable on a cashless basis so long as they are held by the Sponsor or its permitted transferees. The Sponsor and the Company’s officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the Initial Business Combination. Forward Purchase Agreement On April 10, 2017, the Company entered into forward purchase agreement pursuant to which the Sponsor agreed to purchase an aggregate of up to 40,000,000 shares of Class A common stock, plus an aggregate of up to 13,333,333 warrants, for a purchase price of $10.00 per forward purchase unit, or an aggregate purchase price of up to $400,000,000, in a private placement that will close simultaneously with the closing of the Initial Business Combination. The forward purchase warrants will have the same terms as the Private Placement Warrants so long as they are held by the Sponsor or its permitted transferees, and the forward purchase shares will be identical to Public Shares, except that the forward purchase shares will be subject to transfer restrictions and certain registration rights. Any forward purchase warrant held by a holder other than the Sponsor or its permitted transferees will have the same terms as the warrants included in the Units sold in the Public Offering. Registration Rights The holders of Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of working capital loans, if any, will be entitled to registration rights (in the case of the Founder Shares, only after conversion of such shares to shares of Class A common stock) pursuant to a registration rights agreement signed on April 10, 2017. These holders will be entitled to certain demand and “piggyback” registration rights. 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 the applicable lock-up period for the securities to be registered. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Related Party Loans On February 14, 2017, the Sponsor agreed to loan the Company an aggregate of up to $200,000 to cover expenses related to the Public Offering pursuant to an unsecured promissory note (the “ Note Advances from Related Parties An affiliate of the Company’s executive officers and the Sponsor paid certain administrative expenses and offering costs on behalf of the Company. These advances are due on demand and are non-interest bearing. During the period February 8, 2017 (date of inception) to March 31, 2017, these related parties paid $25,857 of offering costs and other expenses on behalf of the Company. During the three months ended March 31, 2018, these related parties paid $79,792 of other expenses on behalf of the Company. As of March 31, 2018, the amount due to the related parties was $0.

Upon completion of the Initial Business Combination or the Company’s liquidation, the Company will cease paying these monthly fees. The Company accrued administrative fees due to the Sponsor of $30,000 for the three months ended March 31, 2018.

Fair Value Measurements The following table presents information about the Company’s assets that are measured on a recurring basis as of March 31, 2018 and December 31, 2017 and indicates the fair value hierarchy of the valuation techniques that the Company utilized to determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable, such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs are unobservable data points for the asset or liability, and includes situations where there is little, if any, market activity for the asset or liability.

Summary of Significant Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim condensed financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“ GAAP The accompanying unaudited interim condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Form 10-K filed by the Company with the SEC on March 27, 2018.
Emerging Growth Company	Emerging Growth Company 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 Securities Exchange Act of 1934, as amended) 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.
Net Income (Loss) Per Share of Common Stock	Net Income (Loss) Per Share of Common Stock Net income (loss) per share of common stock is computed by dividing net income attributable to common shares by the weighted average number of shares of common stock outstanding during the period, plus, to the extent dilutive, the incremental number of shares of common stock to settle warrants, as calculated using the treasury stock method. An aggregate of 53,170,956 shares of Class A common stock subject to possible redemption at March 31, 2018 have been excluded from the calculation of basic net income per share of common stock since such shares, if redeemed, only participate in their pro rata share of the trust earnings. The Company has not considered the effect of the warrants sold in the Public Offering (including the consummation of the overallotment) and private placements of the Private Placement Warrants to purchase an aggregate of 27,093,333 shares of the Company’s Class A common stock in the calculation of diluted net income per share of common stock, since their inclusion would be anti-dilutive under the treasury stock method. At March 31, 2017, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company under the treasury stock method. As a result, diluted loss per common share is the same as basic loss per common share for the period.
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.
Cash and Marketable Securities held in Trust Account	Cash and Marketable Securities held in Trust Account The amounts held in the Trust Account represent net proceeds from the Public Offering and the private placements of Private Placement Warrants of $552,000,000 which were invested in a money market instrument that invests in U.S. Treasury Securities with original maturities of six months or less and are classified as restricted assets because such amounts can only be used by the Company in connection with the consummation of an Initial Business Combination. As of March 31, 2018, cash and marketable securities held in the Trust Account had a fair value of $242,807 and $555,849,755, respectively. At March 31, 2018, there was $4,092,562 of investment income held in the Trust Account available to be released to the Company to pay franchise and income taxes. As of December 31, 2017, cash and marketable securities held in the Trust Account had a fair value of $9,435 and $554,380,922, respectively. At December 31, 2017, there was $2,390,357 of investment income held in the Trust Account available to be released to the Company to pay franchise and income taxes.
Redeemable Common Stock	Redeemable Common Stock As discussed in Note 1, all of the 55,200,000 Public Shares contain a redemption feature which allows for the redemption of Class A common stock under the Company’s liquidation or tender offer/stockholder approval provisions. In accordance with FASB ASC 480, redemption provisions not solely within the control of the Company require the security to be classified outside of permanent equity. Ordinary liquidation events, which involve the redemption and liquidation of all of the entity’s equity instruments, are excluded from the provisions of FASB ASC 480. Although the Company has not specified a maximum redemption threshold, its amended and restated certificate of incorporation provides that in no event will the Company redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001. The Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of the security at the end of each reporting period. Increases or decreases in the carrying amount of redeemable shares of Class A common stock shall be affected by charges against additional paid-in capital. At March 31, 2018, 53,170,956 of the 55,200,000 Public Shares were classified outside of permanent equity. At December 31, 2017, 53,046,079 of the 55,200,000 Public Shares were classified outside of permanent equity.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of cash accounts in a financial institution which, at times, may exceed the Federal depository insurance coverage of $250,000. The Company has not experienced losses on these accounts, and management believes the Company is not exposed to significant risks on such accounts.
Financial Instruments	Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC 820, “ Fair Value Measurements and Disclosures
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with GAAP requires the Company’s 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 expenses during the reporting period. Actual results could differ from those estimates.
Income Taxes	Income Taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC 740, “ Income Taxes FASB 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. There were no unrecognized tax benefits as of March 31, 2018 or December 31, 2017. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties at March 31, 2018 or December 31, 2017. 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. The Company may be subject to potential examination by federal, state, and city taxing authorities in the areas 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.
Related Parties	Related Parties The Company follows subtopic ASC 850-10 for the identification of related parties and disclosure of related party transactions. Pursuant to Section 850-10-20, the related parties include: (a) affiliates of the Company (“Affiliate” means, with respect to any specified person, any other person that, directly or indirectly through one or more intermediaries, controls, is controlled by or is under common control with such person, as such terms are used in and construed under Rule 405 under the Securities Act); (b) entities for which investments in their equity securities would be required, absent the election of the fair value option under the Fair Value Option Subsection of Section 825-10-15, to be accounted for by the equity method by the investing entity; (c) trusts for the benefit of employees, such as pension and profit-sharing trusts that are managed by or under the trusteeship of management; (d) principal owners of the Company; (e) management of the Company; (f) other parties with which the Company may deal if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests; and (g) other parties that can significantly influence the management or operating policies of the transacting parties or that have an ownership interest in one of the transacting parties and can significantly influence the other to an extent that one or more of the transacting parties might be prevented from fully pursuing its own separate interests.
Subsequent Events	Subsequent Events The Company evaluates subsequent events and transactions that occur after the balance sheet date for potential recognition or disclosure. Any material events that occur between the balance sheet date and the date that the financial statements were issued are disclosed as subsequent events, while the financial statements are adjusted to reflect any conditions that existed at the balance sheet date.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company’s management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have an effect on the Company’s financial statements.
