The Company will not generate any operating revenues&#13;until after completion of its Initial Business Combination, at the earliest. The Company will generate non-operating income in&#13;the form of interest income on cash from the proceeds derived from the Public Offering and investment securities purchased with&#13;such proceeds.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 16.5pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 16.5pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;i&gt;Sponsor&#13;and Financing&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 16.5pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;Company&amp;#8217;s sponsor is MP Acquisition Sponsor LLC, a Delaware limited liability company (the &amp;#8220;Sponsor&amp;#8221;).

On March 15, 2017, the Company consummated the Public Offering of 32,500,000 units (&amp;#8220;Units&amp;#8221;&#13;and, with respect to the Class A common stock included in the Units being offered, the &amp;#8220;Public Shares&amp;#8221;), which includes&#13;a partial exercise by Cantor Fitzgerald &amp;#38; Co., the sole underwriter for the Public Offering (the &amp;#8220;Underwriter&amp;#8221;)&#13;of its over-allotment option in the amount of 2,500,000 Units at $10.00 per Unit, generating gross proceeds of $325,000,000, which&#13;is described in Note 3.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 16.5pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Simultaneously&#13;with the closing of the Public Offering and the sale of the Units, the Company consummated a private placement (&amp;#8220;Private&#13;Placement&amp;#8221;) of an aggregate of 15,500,000 warrants (&amp;#8220;Private Placement Warrants&amp;#8221;) at a price of $0.50 per Private&#13;Placement Warrant, to the Sponsor and the Underwriter, generating gross proceeds of $7,750,000, which is described in Note 4.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 16.5pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Transaction&#13;costs amounted to $16,824,469, consisting of $6,000,000 of underwriting fees, $10,250,000 of deferred underwriting commissions&#13;(which are held in the Trust Account (defined below)) and $574,469 of Public Offering costs.

The proceeds held in the Trust Account may&#13;be invested only in U.S. government treasury bills with a maturity of 180 days or less or in money market funds investing solely&#13;in U.S. treasuries and meeting certain conditions under Rule 2a-7 under the Investment Company Act, as determined by the Company,&#13;until the earlier of: (i) the consummation of the Initial Business Combination, or (ii) the distribution of the Trust Account,&#13;as described below, if the Company is unable to complete the Initial Business Combination within 24 months from the closing of&#13;the Public Offering (the &amp;#8220;Combination Period&amp;#8221;) or upon any earlier liquidation of the Company.

The proceeds deposited in the Trust Account could become subject&#13;to the claims of the Company&amp;#8217;s creditors, if any, which could have priority over the claims of the Company&amp;#8217;s public&#13;stockholders.&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;i&gt;Initial&#13;Business Combination&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 24pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;Company&amp;#8217;s management has broad discretion with respect to the specific application of the net proceeds of the Public Offering,&#13;although substantially all of the net proceeds are intended to be applied generally toward consummating the Initial Business Combination.&#13;Nasdaq Capital Market (&amp;#8220;NASDAQ&amp;#8221;) rules provide that the Company&amp;#8217;s Initial Business Combination must be with&#13;one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account&#13;(less any deferred underwriting commissions and taxes payable on interest earned) at the time of the signing of a definitive agreement&#13;in connection with the Initial Business Combination. There is no assurance that the Company will be able to successfully affect&#13;an Initial Business Combination.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;Company will provide its stockholders with the opportunity to redeem all or a portion of their Public Shares upon the completion&#13;of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii)&#13;by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or&#13;conduct a tender offer will be made by the Company, solely in its discretion and will be based on a variety of factors such as&#13;the timing of the transaction and whether the terms of the transaction would require the Company to seek stockholder approval&#13;under applicable law or stock exchange listing requirement. The public stockholders will be entitled to redeem their shares for&#13;a pro rata portion of the amount then on deposit in the Trust Account ($10.00 per share, plus any pro rata interest earned on&#13;the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). The Company will proceed&#13;with an Initial Business Combination only if the Company has net tangible assets of at least $5,000,001 upon such consummation&#13;and a majority of the outstanding shares voted are voted in favor of the Initial Business Combination. If a stockholder vote is&#13;not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company&#13;will, pursuant to its Amended and Restated Certificate of Incorporation, conduct the redemptions pursuant to the tender offer&#13;rules of the SEC, and file tender offer documents with the SEC prior to completing an Initial Business Combination. If, however,&#13;a stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business&#13;or other legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy&#13;rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with an Initial Business&#13;Combination, the Company&amp;#8217;s directors, officers and the Sponsor have agreed to vote their Founder Shares (as defined in Note&#13;4) and any Public Shares they may acquire during or after this offering in favor of approving an Initial Business Combination.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 23.75pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;If&#13;the Company holds a stockholder vote or there is a tender offer for shares in connection with an Initial Business Combination,&#13;a public stockholder will have the right to redeem its shares for an amount in cash equal to its pro rata share of the aggregate&#13;amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination,&#13;including interest but less taxes payable. As a result, such shares of Class A common stock will be recorded at redemption amount&#13;and classified as temporary equity upon the completion of the Public Offering, in accordance with the Financial Accounting Standards&#13;Board (&amp;#8220;FASB&amp;#8221;) Accounting Standards Codification (&amp;#8220;ASC&amp;#8221;) 480, &amp;#8220;Distinguishing Liabilities from Equity.&amp;#8221;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 24pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;Company will also provide its stockholders with the opportunity to redeem all or a portion of their Public Shares in connection&#13;with any stockholder vote to approve an amendment to the Company&amp;#8217;s Amended and Restated Certificate of Incorporation that&#13;would affect the substance or timing of the Company&amp;#8217;s obligation to redeem 100% of Public Shares if it does not complete&#13;a Business Combination within the Combination Period.

The Underwriter also agreed to waive its rights to deferred underwriting commissions held in the&#13;Trust Account in the event the Company does not consummate the Initial Business Combination within the Combination Period and,&#13;in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption&#13;of the Public Shares.

The JOBS Act provides that a company can elect to opt out of the extended transition period and&#13;comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The&#13;Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and&#13;it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the&#13;new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company&amp;#8217;s&#13;financial statements with another public company which is neither an emerging growth company nor an emerging growth company which&#13;has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting&#13;standards used.&lt;/font&gt;&lt;/p&gt;</mpac:EmergingGrowthCompanyPolicyTextBlock>

At March 31, 2017, the Company had outstanding warrants to purchase 24,000,000&#13;shares of common stock. These shares were excluded from the calculation of diluted loss per share of common stock because their&#13;inclusion would have been antidilutive. As a result, diluted loss per common share is the same as basic loss per common share&#13;for the periods. At March 31, 2016, the Company did not have any dilutive securities and other contracts that could, potentially,&#13;be exercised or converted into common stock and then share in the earnings of the Company under the treasury stock method.&lt;/font&gt;&lt;/p&gt;</us-gaap:EarningsPerSharePolicyTextBlock>

In accordance with FASB ASC 480, redemption provisions not solely within the control of the Company require&#13;the security to be classified outside of permanent equity. Ordinary liquidation events, which involve the redemption and liquidation&#13;of all of the entity&amp;#8217;s equity instruments, are excluded from the provisions of FASB ASC 480. Although the Company has not&#13;specified a maximum redemption threshold, its amended and restated certificate of incorporation provides that in no event will&#13;the Company redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 24pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of the security to&#13;equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable Class&#13;A common stock shall be affected by charges against additional paid in capital. Accordingly, at March 31, 2017, 31,092,025 of&#13;the 32,500,000 shares of Class A common stock included in the Units were classified outside of permanent equity at its redemption&#13;value.

Deferred tax assets&#13;and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary&#13;differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates&#13;is recognized in income in the period that included the enactment date.

There were no unrecognized tax benefits as of March 31,&#13;2017. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts&#13;were accrued for the payment of interest and penalties at March 31, 2017. The Company is currently not aware of any issues under&#13;review that could result in significant payments, accruals or material deviation from its position. The Company is subject to&#13;income tax examinations by major taxing authorities since inception.

The JOBS Act provides that a company can elect to opt out of the extended transition period and&#13;comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The&#13;Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and&#13;it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the&#13;new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company&amp;#8217;s&#13;financial statements with another public company which is neither an emerging growth company nor an emerging growth company which&#13;has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting&#13;standards used.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;i&gt;Net&#13;Loss Per Common Share&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;b&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Net&#13;loss per common share is computed by dividing net loss applicable to common stockholders by the weighted average number of common&#13;shares outstanding during the period, plus, to the extent dilutive, the incremental number of shares of common stock to settle&#13;warrants, as calculated using the treasury stock method. At March 31, 2017, the Company had outstanding warrants to purchase 24,000,000&#13;shares of common stock. These shares were excluded from the calculation of diluted loss per share of common stock because their&#13;inclusion would have been antidilutive. As a result, diluted loss per common share is the same as basic loss per common share&#13;for the periods.

In accordance with FASB ASC 480, redemption provisions not solely within the control of the Company require&#13;the security to be classified outside of permanent equity. Ordinary liquidation events, which involve the redemption and liquidation&#13;of all of the entity&amp;#8217;s equity instruments, are excluded from the provisions of FASB ASC 480. Although the Company has not&#13;specified a maximum redemption threshold, its amended and restated certificate of incorporation provides that in no event will&#13;the Company redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 24pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of the security to&#13;equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable Class&#13;A common stock shall be affected by charges against additional paid in capital. Accordingly, at March 31, 2017, 31,092,025 of&#13;the 32,500,000 shares of Class A common stock included in the Units were classified outside of permanent equity at its redemption&#13;value.

Deferred tax assets&#13;and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary&#13;differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates&#13;is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary,&#13;to reduce deferred tax assets to the amount expected to be realized.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 24pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;FASB&#13;ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement&#13;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&#13;likely than not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits as of March 31,&#13;2017. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts&#13;were accrued for the payment of interest and penalties at March 31, 2017. The Company is currently not aware of any issues under&#13;review that could result in significant payments, accruals or material deviation from its position. The Company is subject to&#13;income tax examinations by major taxing authorities since inception. At March 31, 2017 and December 31, 2016, the Company had&#13;no material deferred tax assets.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 24pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;i&gt;Marketable&#13;Securities Held in Trust Account&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;b&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;amounts held in the Trust Account represent proceeds from the Public Offering and the Private Placement of $325,000,000 which&#13;were invested in a money market instrument that invests in United States treasury obligations with original maturities of six&#13;months or less and can only be used by the Company in connection with the consummation of an Initial Business Combination.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;i&gt;Recent&#13;Accounting Pronouncements&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Management&#13;does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have&#13;a material effect on the Company&amp;#8217;s financial statements.&lt;/font&gt;&lt;/p&gt;</us-gaap:BasisOfPresentationAndSignificantAccountingPoliciesTextBlock>

The exercise price and number of shares of common stock issuable upon exercise&#13;of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization,&#13;merger or consolidation. However, the warrants will not be adjusted for issuance of common stock at a price below its exercise&#13;price. Additionally, in no event will the Company be required to net cash settle the warrants. If the Company is unable to complete&#13;an Initial Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account,&#13;holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution&#13;from the Company&amp;#8217;s assets held outside of the Trust Account with the respect to such warrants.
