Significant Accounting Policies (Policies)

12 Months Ended

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation

The accompanying financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America and pursuant to the rules and regulations of the SEC.

Earnings Per Share, Policy [Policy Text Block]

Net Loss Per Ordinary Share

Basic net income (loss) per ordinary share is computed by dividing net income (loss) by the weighted average number of ordinary shares outstanding during the period. Diluted net income/loss per share is computed by dividing net income (loss) per share by the weighted average number of ordinary shares outstanding (including shares subject to redemption), plus, to the extent dilutive, the incremental number of ordinary shares to settle private placement warrants held by the Sponsor, as calculated using the treasury stock method. Class A ordinary shares subject to possible redemption for the periods presented have been excluded from the calculation of basic income (loss) per ordinary shares since such shares, if redeemed, only participate in their pro rata share of the trust earnings. The redeemable shares are included within the diluted per share calculation for the year ended December 31, 2016. The Company has not considered the effect of warrants sold in the Initial Public Offering in the calculation of diluted income (loss) per share, since their inclusion would be anti-dilutive.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

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.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value of 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,” approximates the carrying amounts represented in the balance sheet with the exception of investments in Trust, as they are carried at amortized cost.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 revenue and expenses during the reporting period. Actual results could differ from those estimates.

Offering Costs Policy [Policy Text Block]

Offering Costs

The Company complies with the requirements of FASB ASC 340-10-S99-1 and SEC Staff Accounting Bulletin (“SAB”) Topic 5A, “Expenses of Offering.” Offering costs of approximately $28,290,000, consisting principally of underwriter discounts of $27,500,000 (including approximately $19,500,000 of which payment is deferred) and approximately $790,000 of professional, printing, filing, regulatory and other costs were charged to shareholders’ equity upon completion of the Public Offering. Approximately $0 and $100,000 of such offering expenses were accrued but unpaid at December 31, 2016 and 2015, respectively.

Stockholders' Equity Note, Redeemable Preferred Stock, Issue, Policy [Policy Text Block]

Redeemable Ordinary Shares

As discussed in Note 1, all of the 50,000,000 Class A ordinary shares sold as parts of the Units in the Public Offering contain a redemption feature which allows for the redemption of Class A ordinary shares under the Company's amended and restated memorandum and articles of association. 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 memorandum and articles of association provide 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 to equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable Class A ordinary shares shall be affected by charges against additional paid in capital. Accordingly, at December 31, 2016 and 2015, 47,702,674 and 47,646,408 shares, respectively, of the 50,000,000 Class A ordinary shares included in the Units were classified outside of permanent equity at its redemption value.

Income Tax, Policy [Policy Text Block]

Income Taxes

The Company complies with the accounting and reporting requirements of FASB ASC 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 amounts expected to be realized.

There were no unrecognized tax benefits as of December 31, 2016. 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. 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 December 31, 2016. 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 has been subject to income tax examinations by major taxing authorities since inception.

There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman federal income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company's financial statements. The Company's management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting Pronouncements

In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). ASU 2014-15 provides guidance on management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The amendments in ASU 2014-15 are effective for annual reporting periods ending after December 15, 2016 and for annual and interim periods thereafter. Early adoption is permitted. The Company has adopted the methodologies prescribed by ASU 2014-15, and it did not have an effect on its financial position or results of operations.

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