Organization and Plan of Business Operations
Organization and Plan of Business Operations	Note 1—Organization and Plan of Business Operations Organization and General Avista Healthcare Public Acquisition Corp. (the “Company”) was incorporated as a Cayman Islands exempted company on December 4, 2015. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”). The Company intends to focus its search for a target business in the healthcare industry, although it may seek to complete a Business Combination with an operating company in any industry or sector. The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (as amended, the “JOBS Act”). The Company’s sponsor is Avista Acquisition Corp. (the “Sponsor”), which was incorporated on December 4, 2015. At March 31, 2017, the Company had not commenced any operations. All activity through March 31, 2017 relates to the Company’s formation, its initial public offering of 30,000,000 units (the “Units”) at $10.00 per Unit, each consisting of one of the Company’s Class A ordinary shares, par value $0.0001 per share (the “Class A Shares”), and one warrant (the “Warrants”) to purchase one-half of one Class A Share (the “Public Offering”) and efforts directed towards locating a suitable initial Business Combination. The Company also granted the Underwriters (as defined below) of the Public Offering a 45-day option to purchase up to 4,500,000 additional Units to cover over-allotments (the “Over-allotment Option”). The Class A Shares sold as part of the Units in the Public Offering are sometimes referred to herein as the “public shares.” The Company will not generate any operating revenues until after completion of a Business Combination, at the earliest. The Company has selected December 31 as its fiscal year end. Financing The registration statement for the Company’s Public Offering was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on October 7, 2016. The Public Offering closed on October 14, 2016 (the “Close Date”). The Sponsor and certain other accredited investors (the “Initial Shareholders”) purchased an aggregate of 16,000,000 warrants (the “Private Placement Warrants”) at a purchase price of $0.50 per warrant, or $8,000,000 in the aggregate, in a private placement at the Close Date (the “Private Placement”). On November 28, 2016, the Company consummated the closing of the sale of 1,000,000 Units which were sold pursuant to the Over-allotment Option. The Company also consummated a simultaneous private placement of an additional 400,000 Private Placement Warrants with the Initial Shareholders. Following the closing of the Over-allotment Option and Private Placement, an additional $10,000,000 was placed into the Trust Account, after paying additional underwriting discounts of $200,000. The Company intends to finance a Business Combination with net proceeds from its $310,000,000 Public Offering and $8,200,000 Private Placement (see Note 3). Following the Public Offering, after paying underwriting discounts of $6,200,000 and funds designated for operational use of $2,000,000, the remaining net proceeds of $310,000,000 were deposited in a trust account with Continental Stock Transfer and Trust Company acting as trustee (the “Trust Account”) as described below. The Trust Account On January 6, 2017, the funds in the Trust Account were invested in U.S. government treasury bills, which matured on April 6, 2017. On April 6, 2017, the funds in the Trust Account were reinvested in US government treasury bills, maturing on July 6, 2017, until the earlier of (i) the consummation of the Business Combination and (ii) the Company’s failure to consummate a Business Combination within the prescribed time. Placing funds in the Trust Account may not protect those funds from third-party claims against the Company. Although the Company will seek to have all vendors, service providers (other than its independent auditors), prospective target businesses or other entities it engages execute agreements with the Company waiving any claim of any kind in or to any monies held in the Trust Account, there is no guarantee that such persons will execute such agreements. The Sponsor has agreed that it will be liable to the Company under certain circumstances if and to the extent any claims by such persons reduce the amount of funds in the Trust Account below a specified threshold. The Company has not independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believes that the Sponsor’s only assets are securities of the Company. Therefore, the Sponsor may not be able to satisfy those obligations should they arise. The remaining net proceeds (not held in the Trust Account) may be used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses as well as any taxes. The balance in the Trust Account as of March 31, 2017 was $310,359,511, of this amount $359,511 was accrued interest. Business Combination The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Public Offering, the sale of the Private Placement Warrants and the Over-allotment Option, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to successfully effect a Business Combination. The Company will provide the holders of the public shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their public shares upon the completion of the Business Combination, either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer, in either case at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest (which interest shall be net of taxes payable) divided by the number of then outstanding public shares. Notwithstanding the foregoing, if the Company seeks shareholder approval of the Business Combination and the Company does not conduct redemptions pursuant to the tender offer rules, a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the public shares. In connection with any shareholder vote required to approve any Business Combination, the Initial Shareholders have agreed (i) to vote any of their respective Ordinary Shares (as defined below) in favor of the Business Combination and (ii) not to redeem any of their Ordinary Shares in connection therewith. The NASDAQ rules require that the Business Combination must be with one or more target businesses that together have an aggregate fair market value equal to at least 80% of the balance in the Trust Account (less any Deferred Commissions (as defined below) and taxes payable on interest earned) at the time of the Company signing a definitive agreement in connection with the Business Combination. If the Company has not completed a Business Combination by October 14, 2018, 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 (which interest shall be net of taxes payable, and less up to $50,000 of interest to pay dissolution expenses) divided by the number of then outstanding public shares, which redemption will completely extinguish the rights of the Public Shareholders as Shareholders (including the right to receive further liquidation 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 shareholders and its Board of Directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In the event of a liquidation, the Public Shareholders will be entitled to receive a full pro rata interest in the Trust Account (initially anticipated to be approximately $10.00 per share, plus any pro rata interest earned on the Trust Fund not previously released to the Company and less up to $50,000 of interest to pay dissolution expenses). There will be no redemption rights or liquidating distributions with respect to the Founder Shares (as defined below) or the Private Placement Warrants, which will expire worthless if the Company fails to complete a Business Combination within the 24-month time period. Liquidity As of March 31, 2017, the Company had $345,377 in cash held outside of the Trust Account available for working capital purposes. In order to preserve liquidity, as of April 30, 2017, the affiliate of the Sponsor (the “Affiliate”) has agreed to defer payment of the monthly administrative fee under the Administrative Services Agreement until the initial Business Combination, at which time all such accrued but unpaid fees will be paid to the Affiliate. If needed to finance ongoing operating expenses, the Sponsor may, but is not obligated to, make working capital loans to the Company, as noted in Note 6. Based on the foregoing, management believes that the Company will have sufficient working capital to continue as a going concern.

Significant Accounting Policies	Note 2—Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed financial statements have been prepared in U.S dollars in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Certain information or footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all of the information and footnotes necessary for a comprehensive presentation of the financial position, results of operations or cash flows. In the opinion of management, the accompanying unaudited condensed financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The accompanying unaudited condensed financial statements should be read in conjunction with the Company’s final prospectus as filed with the SEC on October 10, 2016 and declared effective on October 7, 2016, as well as the Company’s form 8-K, as filed with the SEC on October 20, 2016. Operating results for the three months ended March 31, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 or any other future period. 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 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 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. Use of Estimates The preparation of the Company’s financial statements in conformity with US 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. Actual results could differ from those estimates. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. 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 FASB ASC 820, Fair Value Measurements and Disclosures, approximates the carrying amounts represented in the balance sheet. Fair Value Measurement ASC 820 establishes a fair value hierarchy that prioritizes and ranks the level of observability of inputs used to measure investments at fair value. The observability of inputs is impacted by a number of factors, including the type of investment, characteristics specific to the investment, market conditions and other factors. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements). Investments with readily available quoted prices or for which fair value can be measured from quoted prices in active markets will typically have a higher degree of input observability and a lesser degree of judgment applied in determining fair value. The three levels of the fair value hierarchy under ASC 820 are as follows: Level I — Quoted prices (unadjusted) in active markets for identical investments at the measurement date are used. Level II — Pricing inputs are other than quoted prices included within Level I that are observable for the investment, either directly or indirectly. Level II pricing inputs include quoted prices for similar investments in active markets, quoted prices for identical or similar investments in markets that are not active, inputs other than quoted prices that are observable for the investment, and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level III — Pricing inputs are unobservable and include situations where there is little, if any, market activity for the investment. The inputs used in determination of fair value require significant judgment and estimation. In some cases, the inputs used to measure fair value might fall within different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the investment is categorized in its entirety is determined based on the lowest level input that is significant to the investment. Assessing the significance of a particular input to the valuation of an investment in its entirety requires judgment and considers factors specific to the investment. The categorization of an investment within the hierarchy is based upon the pricing transparency of the investment and does not necessarily correspond to the perceived risk of that investment. Offering Costs The Company complies with the requirements of ASC 340-10-S99-1 and SEC Staff Accounting Bulletin Topic 5A; “Expenses of Offering”. The Company incurred offering costs in connection with its Public Offering of $833,589, primarily consisting of accounting and legal services, securities registration expenses and exchange listing fees, and excluding $6,200,000 in underwriting discounts and $10,850,000 in deferred underwriting discounts. These offering costs, along with underwriting discounts, were charged to shareholders’ equity. Net Income Per Share Net income/(loss) per ordinary share is computed by dividing net income attributable to ordinary shares by the weighted average number of ordinary shares outstanding during the period (excluding 29,490,640 Class A Shares subject to possible redemption as of March 31, 2017 and 1,125,000 Class B Shares subject to forfeiture as of March 31, 2016), plus, to the extent dilutive, the incremental number of Class A Shares to settle the Private Placement Warrants and the Warrants included in the Units. At March 31, 2017, the Company had outstanding warrants for the purchase of up to 23,700,000 Class A Shares. For the period ended March 31, 2017, the weighted average of these shares was excluded from the calculation of diluted net income per ordinary share since the exercise of the warrants is contingent on the occurance of future events. As a result, diluted net income per ordinary share is equal to basic net income/(loss) per ordinary share. Income Taxes The Company accounts for income taxes under FASB ASC 740, Income Taxes (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized. ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position 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. There were no unrecognized tax benefits as of March 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. There is currently no taxation imposed on income by the Government of the Cayman Islands. Recent Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying balance sheet. Subsequent Events On April 6, 2017, the Company invested the funds held in the Trust Account in U.S. Treasury Bills maturing on July 6, 2017. Other than the foregoing, management has performed an evaluation of subsequent events from March 31, 2017 through the date which these financial statements were issued. Based upon the review, management did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the financial statements.

Related Party Transactions
Related Party Transactions	Note 6—Related Party Transactions Related Party Loans The Company issued to the Sponsor on December 14, 2015, as amended and restated on September 1, 2016, an unsecured promissory note pursuant to which the Company was permitted to borrow up to $300,000 in aggregate principal amount. Between inception and the Close Date, the Company borrowed $300,000. This note was non-interest bearing and was repaid in full to the Sponsor at the Close Date. The Sponsor may make a working capital loan to the Company and up to $1,500,000 of such loan may be converted into warrants, at the price of $0.50 per warrant at the option of the Sponsor. Such warrants would be identical to the Private Placement Warrants. Administrative Services Agreement The Company presently occupies office space provided by an Affiliate. The Affiliate has agreed that, until the Company consummates a Business Combination, it will make such office space, as well as certain support services, available to the Company, as may be required by the Company from time to time. The Company will pay the Affiliate an aggregate of $10,000 per month for such office space and support services. As of April 30, 2017, the Affiliate has agreed to defer payment of the monthly administrative fee under the Administrative Services Agreement until the initial Business Combination, at which time all such accrued but unpaid fees will be paid to the Affiliate. Private Placement Warrants The Initial Shareholders purchased 16,000,000 Private Placement Warrants at $0.50 per warrant (for an aggregate purchase price of $8,000,000) from the Company in a Private Placement on the Close Date. A portion of the proceeds from the sale of the Private Placement Warrants were placed into the Trust Account. The Initial Shareholders have also purchased an additional 400,000 Private Placement Warrants at $0.50 per warrant (for an aggregate purchase price of $200,000) simultaneously with the underwriter’s exercise of the Over-Allotment Option. Each Private Placement Warrant is exercisable for one-half of one Class A Share. Two Private Placement Warrants must be exercised for one whole Class A Share at a price of $11.50 per share. The Private Placement Warrants are identical to the Warrants included in the Units to be sold in the Public Offering except that the Private Placement Warrants: (i) will not be redeemable by the Company and (ii) may be exercised for cash or on a cashless basis, as described in the registration statement relating to the Public Offering, so long as they are held by the Initial Shareholders or any of their permitted transferees. Additionally, the Initial Shareholders have agreed not to transfer, assign or sell any of the Private Placement Warrants, including the Class A Shares issuable upon exercise of the Private Placement Warrants (except to certain permitted transferees), until 30 days after the completion of the Business Combination. Founder Shares In connection with the organization of the Company, on December 14, 2015, an aggregate of 8,625,000 Class B Shares (the “Founder Shares”) were sold to the Sponsor at a price of approximately $0.003 per share, for an aggregate price of $25,000. In October 2016, the Sponsor transferred 50,000 Founder Shares to each of the Company’s independent directors at a price per share of approximately $0.003 per share. In addition, at such time, each of our independent directors purchased an additional 421,250 Founder Shares from our Sponsor at a price per share of approximately $0.003 per share. The 8,625,000 Founder Shares included an aggregate of up to 1,125,000 shares that were subject to forfeiture if the Over-allotment Option was not exercised in full by the Underwriters in order to maintain the Initial Shareholders’ ownership at 20% of the issued and outstanding Ordinary Shares upon completion of the Public Offering. Following the partial exercise of the Over-allotment Option, 875,000 Founder Shares were forfeited in order to maintain the Initial Shareholder’s ownership at 20% of the issued and outstanding Ordinary shares. The Founder Shares are identical to the Class A Shares included in the Units sold in the Public Offering, except that the Founder Shares (i) have the voting rights described in Note 7, (ii) are subject to certain transfer restrictions described below, and (iii) are convertible into Class A Shares on a one-for-one basis, subject to adjustment pursuant to the anti-dilution provisions contained therein. The Founder Shares may not be transferred, assigned or sold until the earlier of (i) one year after the completion of the Business Combination and (ii) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction after the Business Combination that results in all of the Public Shareholders having the right to exchange their Class A Shares for cash, securities or other property. Notwithstanding the foregoing, if the last sale price of the Class A Shares equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 trading day period commencing at least 150 days after the Business Combination, the Founder Shares will be released from the lock-up.

Shareholders' Equity
Shareholders' Equity	Note 7—Shareholders’ Equity Preferred Shares The Company is authorized to issue 1,000,000 preferred shares with a par value of $0.0001. The Company’s board of directors will be authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. The board of directors will be able to, without shareholder approval, issue preferred shares with voting and other rights that could adversely affect the voting power and other rights of the holders of the Ordinary Shares and could have anti-takeover effects. At March 31, 2017 there were no preferred shares issued or outstanding. Ordinary Shares The Company is authorized to issue 200,000,000 Class A Shares, with a par value of $0.0001 each, and 20,000,000 Class B ordinary shares, with a par value of $0.0001 each (the “Class B Shares” and, together with the Class A Shares, the “Ordinary Shares”). Holders of the Ordinary Shares are entitled to one vote for each Ordinary Share; provided, that only holders of the Class B Shares have the right to vote on the election of directors prior to the Business Combination. The Class B Shares will automatically convert into Class A Shares at the time of the Business Combination, on a one-for-one basis, subject to adjustment for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional Class A Shares, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in the Public Offering and related to the closing of the Business Combination, the ratio at which the Class B Shares shall convert into Class A Shares will be adjusted (unless the holders of a majority of the outstanding Class B ordinary shares agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of Class A Shares issuable upon conversion of all Class B Shares will equal, in the aggregate, 20% of the sum of all Ordinary Shares outstanding upon completion of the Public Offering plus all Class A Shares and equity-linked securities issued or deemed issued in connection with the Business Combination, excluding any Ordinary Shares or equity-linked securities issued, or to be issued, to any seller in the Business Combination. Holders of Founder Shares may also elect to convert their Class B Shares into an equal number of Class A Shares, subject to adjustment as provided above, at any time. At March 31, 2017 there were 31,000,000 Class A Shares issued and outstanding, of which 29,490,640 shares were subject to possible redemption and are classified outside of shareholders’ equity at the balance sheet date and 7,750,000 Class B Shares issued and outstanding. Redeemable Ordinary Shares The Class A Shares subject to possible redemption will be recorded at redemption value and classified as temporary equity in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 480, Distinguishing Liabilities from Equity. The Company will proceed with a Business Combination only if it has net tangible assets of at least $5,000,001 upon consummation of the Business Combination and, in the case of a shareholder vote, a majority of the outstanding Ordinary Shares voted are voted in favor of the Business Combination. Accordingly, at March 31, 2017, 29,490,640 of the Company’s 31,000,000 Class A Shares were classified outside of permanent equity at their redemption value.

Significant Accounting Policies (Policies)	3 Months Ended
Significant Accounting Policies (Policies)	Mar. 31, 2017
Significant Accounting Policies
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed financial statements have been prepared in U.S dollars in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Certain information or footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all of the information and footnotes necessary for a comprehensive presentation of the financial position, results of operations or cash flows. In the opinion of management, the accompanying unaudited condensed financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The accompanying unaudited condensed financial statements should be read in conjunction with the Company’s final prospectus as filed with the SEC on October 10, 2016 and declared effective on October 7, 2016, as well as the Company’s form 8-K, as filed with the SEC on October 20, 2016. Operating results for the three months ended March 31, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 or any other future period.
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 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 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.
Use of Estimates	Use of Estimates The preparation of the Company’s financial statements in conformity with US 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. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.
Concentration of Credit Risk	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	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.
Fair Value Measurement	Fair Value Measurement ASC 820 establishes a fair value hierarchy that prioritizes and ranks the level of observability of inputs used to measure investments at fair value. The observability of inputs is impacted by a number of factors, including the type of investment, characteristics specific to the investment, market conditions and other factors. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements). Investments with readily available quoted prices or for which fair value can be measured from quoted prices in active markets will typically have a higher degree of input observability and a lesser degree of judgment applied in determining fair value. The three levels of the fair value hierarchy under ASC 820 are as follows: Level I — Quoted prices (unadjusted) in active markets for identical investments at the measurement date are used. Level II — Pricing inputs are other than quoted prices included within Level I that are observable for the investment, either directly or indirectly. Level II pricing inputs include quoted prices for similar investments in active markets, quoted prices for identical or similar investments in markets that are not active, inputs other than quoted prices that are observable for the investment, and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level III — Pricing inputs are unobservable and include situations where there is little, if any, market activity for the investment. The inputs used in determination of fair value require significant judgment and estimation. In some cases, the inputs used to measure fair value might fall within different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the investment is categorized in its entirety is determined based on the lowest level input that is significant to the investment. Assessing the significance of a particular input to the valuation of an investment in its entirety requires judgment and considers factors specific to the investment. The categorization of an investment within the hierarchy is based upon the pricing transparency of the investment and does not necessarily correspond to the perceived risk of that investment.
Offering Costs	Offering Costs The Company complies with the requirements of ASC 340-10-S99-1 and SEC Staff Accounting Bulletin Topic 5A; “Expenses of Offering”. The Company incurred offering costs in connection with its Public Offering of $833,589, primarily consisting of accounting and legal services, securities registration expenses and exchange listing fees, and excluding $6,200,000 in underwriting discounts and $10,850,000 in deferred underwriting discounts. These offering costs, along with underwriting discounts, were charged to shareholders’ equity.
Net Income Per Share	Net Income Per Share Net income/(loss) per ordinary share is computed by dividing net income attributable to ordinary shares by the weighted average number of ordinary shares outstanding during the period (excluding 29,490,640 Class A Shares subject to possible redemption as of March 31, 2017 and 1,125,000 Class B Shares subject to forfeiture as of March 31, 2016), plus, to the extent dilutive, the incremental number of Class A Shares to settle the Private Placement Warrants and the Warrants included in the Units. At March 31, 2017, the Company had outstanding warrants for the purchase of up to 23,700,000 Class A Shares. For the period ended March 31, 2017, the weighted average of these shares was excluded from the calculation of diluted net income per ordinary share since the exercise of the warrants is contingent on the occurance of future events. As a result, diluted net income per ordinary share is equal to basic net income/(loss) per ordinary share.
Income Taxes	Income Taxes The Company accounts for income taxes under FASB ASC 740, Income Taxes (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized. ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position 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. There were no unrecognized tax benefits as of March 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. There is currently no taxation imposed on income by the Government of the Cayman Islands.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying balance sheet.
Subsequent Events	Subsequent Events On April 6, 2017, the Company invested the funds held in the Trust Account in U.S. Treasury Bills maturing on July 6, 2017. Other than the foregoing, management has performed an evaluation of subsequent events from March 31, 2017 through the date which these financial statements were issued. Based upon the review, management did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the financial statements.

Commitments	Note 4—Commitments Underwriting Agreement The Company entered into an agreement with the underwriters (the “Underwriters”) of the Public Offering (“Underwriting Agreement”) that required the Company to pay an underwriting discount of 2.0% of the gross proceeds of the Public Offering and Over-allotment Option to the Underwriters at the Close Date of the Public Offering. The Company will pay the Underwriters a deferred underwriting discount of 3.5% of the gross proceeds of the Public Offering and Over-allotment Option (“Deferred Commissions”) at the time of the closing of the Business Combination. The Deferred Commission was placed in the Trust Account at the completion of the Public Offering and will be forfeited if the Company is unable to complete a Business Combination in the prescribed time. Registration Rights Holders of the Founder Shares, the Private Placement Warrants, and warrants that may be issued on conversion of working capital loans (and any Class A Shares issuable upon exercise of such warrants and upon conversion of the Founder Shares) will be entitled to registration rights with respect to such securities (in the case of the Founder Shares, only after conversion to Class A Shares) pursuant to an agreement signed on the effective date of the Public Offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities for resale. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the Business Combination. However, the registration rights agreement will provide that the Company will not permit any registration statement to become effective until termination of applicable lock-up periods with respect to such securities.
