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”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (“SEC”), and reflect all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the financial position as of June 30, 2017 and the results of operations and cash flows for the period presented. Certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. Interim results are not necessarily indicative of results for a full year. The accompanying unaudited interim condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the final prospectus filed by the Company with the SEC on March 30, 2017 and with the audited balance sheet included in the Form 8-K filed by the Company with the SEC on April 10, 2017 and the unaudited pro forma balance sheet included in the Form 8-K filed by the Company with the SEC on April 26, 2017. *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 and Exchange Act of 1934, as amended, or the “Exchange Act”) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an 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 statement 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 Loss Per Common Share* Net loss per common share is computed by dividing net loss applicable to common stockholders by the weighted average number of common shares 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. The weighted average shares outstanding for the three and six months ended June 30, 2017 excludes 629,472 shares which were subsequently forfeited by the Sponsor (see Note 4). At June 30, 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. *Concentration of Credit Risk* Financial instruments that potentially subject the Company to concentrations 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 the FASB ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheet. *Use of Estimates* The preparation of 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 revenues and expenses during the reporting period. Actual results could differ from those estimates. *Deferred Offering Costs* The Company complies with the requirements of the FASB ASC 340-10-S99-1 and SEC Staff Accounting Bulletin Topic 5A—“Expenses of Offering.” The Company incurred approximately $674,000 of offering costs in connection with preparation for the Public Offering. These costs together with the underwriting discounts of $20,752,661 (including $13,206,239 of which payment is deferred), were charged to additional paid in capital upon completion of the Public Offering in April 2017. *Income Taxes* The Company follows the asset and liability method of accounting for income taxes under FASB ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. 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 June 30, 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 June 30, 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. During the three and six months ended June 30, 2017, the Company recorded income tax expense of $170,349 primarily related to interest income earned on the trust account. Until the Company completes an Initial Business Combination, its general and administrative expenses will be deferred for tax purposes. At June 30, 2017, the Company has a deferred tax asset of approximately $372,000 primarily related to the deferral of its general and administrative expenses. Management has determined that a full valuation allowance on the deferred tax asset is appropriate at this time after consideration of all available positive and negative evidence related to the realization of the deferred tax asset. The Company’s effective tax rate for the three and six months ended June 30, 2017 was -30% which is a result of the full valuation allowance against its deferred tax asset. *Recent Accounting Pronouncements* The Company’s management does not believe any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.

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”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (“SEC”), and reflect all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the financial position as of June 30, 2017 and the results of operations and cash flows for the period presented. Certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. Interim results are not necessarily indicative of results for a full year.

The accompanying unaudited interim condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the final prospectus filed by the Company with the SEC on March 30, 2017 and with the audited balance sheet included in the Form 8-K filed by the Company with the SEC on April 10, 2017 and the unaudited pro forma balance sheet included in the Form 8-K filed by the Company with the SEC on April 26, 2017.

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 and Exchange Act of 1934, as amended, or the “Exchange Act”) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an 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 statement 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 Loss Per Common Share

Net loss per common share is computed by dividing net loss applicable to common stockholders by the weighted average number of common shares 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. The weighted average shares outstanding for the three and six months ended June 30, 2017 excludes 629,472 shares which were subsequently forfeited by the Sponsor (see Note 4). At June 30, 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.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations 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 the FASB ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheet.

Use of Estimates

The preparation of 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 revenues and expenses during the reporting period. Actual results could differ from those estimates.

Deferred Offering Costs

The Company complies with the requirements of the FASB ASC 340-10-S99-1 and SEC Staff Accounting Bulletin Topic 5A—“Expenses of Offering.” The Company incurred approximately $674,000 of offering costs in connection with preparation for the Public Offering. These costs together with the underwriting discounts of $20,752,661 (including $13,206,239 of which payment is deferred), were charged to additional paid in capital upon completion of the Public Offering in April 2017.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under FASB ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

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 June 30, 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 June 30, 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.

During the three and six months ended June 30, 2017, the Company recorded income tax expense of $170,349 primarily related to interest income earned on the trust account. Until the Company completes an Initial Business Combination, its general and administrative expenses will be deferred for tax purposes.

At June 30, 2017, the Company has a deferred tax asset of approximately $372,000 primarily related to the deferral of its general and administrative expenses. Management has determined that a full valuation allowance on the deferred tax asset is appropriate at this time after consideration of all available positive and negative evidence related to the realization of the deferred tax asset.

The Company’s effective tax rate for the three and six months ended June 30, 2017 was -30% which is a result of the full valuation allowance against its deferred tax asset.

Recent Accounting Pronouncements

The Company’s management does not believe any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.
