Subsequent Events [Abstract]
Subsequent Events	Note 9 — Subsequent Events The Company follows the guidance in Section 855-10-50 of the FASB Accounting Standards Codification for the disclosure of subsequent events. The Company evaluated subsequent events through the date when the financial statements were issued. On February 26, 2018, the Company entered into a Contribution Agreement dated February 26, 2018 with Priority Investment Holdings, LLC and Priority Incentive Equity Holdings, LLC to acquire all of the outstanding equity interests of Priority Holdings, LLC, a leading provider of B2C and B2B payment processing solutions. On March 26, 2018, the Company entered into an Amended and Restated Contribution Agreement with the Interest Holders (as amended and restated, the “Purchase Agreement”). Upon the closing of the transactions contemplated in the Purchase Agreement, M I will acquire (the “Acquisition”) 100% of the issued and outstanding equity securities of Priority, as well as assume certain of Priority’s debt, in exchange for a number of shares of our common stock equal to Priority’s equity value (which the Purchase Agreement defines as of the signing date as $947,835,000 enterprise value of Priority less the net debt of Priority at closing, subject to certain adjustments as described below) divided by $10.30. If Priority acquires any businesses prior to the closing of the Acquisition that increase Priority’s Adjusted EBITDA in aggregate by more than $9 million, Priority’s enterprise value will increase by multiplying the incremental increase in Adjusted EBITDA of such acquisition by 12.5, provided that estimated synergies related to any such acquisitions included in the Adjusted EBITDA calculation of Priority shall be capped at 20% of the Adjusted EBITDA of the applicable acquisition with respect to the 12-month period immediately preceding the consummation of such acquisition. In connection with the Acquisition, we will change our name to Priority Technology Holdings, Inc. In addition, any cash that Priority spends to acquire any technology assets, up to $5,000,000, to purchase securities from the Founders pursuant to the Promote Agreement described below or to extend the time we have to complete a business combination, such amounts will be included in the calculation of net debt as cash and cash equivalents (which would reduce the amount of net debt, effectively increasing the assumed enterprise value of Priority and increasing the number of shares that would be issued to the Interest Holders). An additional 9.8 million shares may be issued as earn out consideration to the Interest Holders and members of management or other service providers of the post-Acquisition company—4.9 million shares for the first earn out and 4.9 million shares for the second earn out. For the first earn out, Adjusted EBITDA must be no less than $82.5 million for the year ending December 31, 2018 and the stock price must have traded in excess of $12.00 for any 20 trading days within any consecutive 30-day trading period at any time on or before December 31, 2019. For the second earn out, Adjusted EBITDA must be no less than $91.5 million for the year ending December 31, 2019 and the stock price must have traded in excess of $14.00 for any 20 trading days within any consecutive 30-day trading period at any time between January 1, 2019 and December 31, 2020. In the event that the first earn out targets are not met, the entire 9.8 million shares may be issued if the second earn out targets are met. Concurrently with the Purchase Agreement, our founding stockholders (the “Founders”) and Priority entered into a purchase agreement (the “Promote Agreement”) pursuant to which Priority agreed to purchase 421,107 of the units issued to the Founders in a private placement immediately prior to M I’s initial public offering, and 453,210 shares of common stock of M I issued to the Founders for an aggregate purchase price of approximately $2.1 million. In addition, pursuant to the Promote Agreement, the Founders will forfeit 174,863 founder’s shares at the closing of the Acquisition, which shares may be reissued to the Founders if one of the earn outs described above is achieved. In addition, the Founders and Thomas C. Priore, the Executive Chairman of Priority (“TCP”), entered into a letter agreement (the “Letter Agreement”) pursuant to which the Founders granted TCP (i) the right to purchase the Founders’ remaining shares of our common stock at the prevailing market price subject to certain conditions including a floor of $10.30 per share and (ii) a right of first refusal on the shares. On March 13, 2018, the Company issued promissory notes in the aggregate principal amount of $132,753 to its sponsors (M SPAC LLC, M SPAC Holdings I, LLC and M SPAC Holdings II, LLC). The $132,753 received by the Company upon issuance of the notes was deposited into the Company’s trust account for the benefit of its public stockholders in order to extend the period of time the Company has to complete a business combination for an additional one month, from March 19, 2018 to April 19, 2018. The notes do not bear interest and are payable five business days after the date the Company completes a business combination.

The Company follows the guidance in Section 855-10-50 of the FASB Accounting Standards Codification for the disclosure of subsequent events. The Company evaluated subsequent events through the date when the financial statements were issued.

On February 26, 2018, the Company entered into a Contribution Agreement dated February 26, 2018 with Priority Investment Holdings, LLC and Priority Incentive Equity Holdings, LLC to acquire all of the outstanding equity interests of Priority Holdings, LLC, a leading provider of B2C and B2B payment processing solutions. On March 26, 2018, the Company entered into an Amended and Restated Contribution Agreement with the Interest Holders (as amended and restated, the “Purchase Agreement”).

Upon the closing of the transactions contemplated in the Purchase Agreement, M I will acquire (the “Acquisition”) 100% of the issued and outstanding equity securities of Priority, as well as assume certain of Priority’s debt, in exchange for a number of shares of our common stock equal to Priority’s equity value (which the Purchase Agreement defines as of the signing date as $947,835,000 enterprise value of Priority less the net debt of Priority at closing, subject to certain adjustments as described below) divided by $10.30.
