Description of Organization and Business Operations	Note 1. Description of Organization and Business Operations Organizational and General Regalwood Global Energy Ltd. (the “Company”) is a blank check company incorporated in the Cayman Islands on September 14, 2017. 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 (an “Initial Business Combination”). Although the Company is not limited to a particular industry or geographic region for purposes of consummating its Initial Business Combination, the Company intends to make investments in oil and gas exploration and production, midstream, refining and marketing and energy services companies outside of North America that may provide opportunities for attractive risk-adjusted returns. 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 (the “JOBS Act”). As of September 30, 2019, the Company had not yet commenced operations. All activity through September 30, 2019 relates to the Company’s formation, the preparation for the initial public offering (the “Public Offering”) and the search for a prospective Initial Business Combination. The Company will not generate any operating revenues until after completion of its Initial Business Combination, at the earliest. The Company generates non-operating The Company intends to finance its Initial Business Combination with proceeds from the Public Offering (Note 3), the sale of the Private Placement Warrants (Note 3), and additional issuances of the Company’s capital stock, debt or a combination of the foregoing. Upon the closings of the Public Offering and the sale of the Private Placement Warrants, $300,000,000 was placed in a trust account (the “Trust Account”) (discussed below). The registration statement for the Company’s Public Offering (as described in Note 3) was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on November 30, 2017. On October 3, 2018, the Company received notice from the New York Stock Exchange (the “NYSE”) that it was not currently in compliance with the requirement of Section 802.01B of the New York Stock Exchange Listed Company Manual (the “Manual”) that the Company’s Class A ordinary shares be held by a minimum of 300 public shareholders. Pursuant to such notice, the Company is subject to the procedures set forth in Sections 801 and 802 of the Manual. The Company submitted a business plan that demonstrates how the Company expects to return to compliance with the minimum public shareholders requirement within 18 months of receipt of the notice. The Company anticipates that it will satisfy this listing requirement within such time period once it locates a target business with which to consummate an initial business combination. Trust Account The proceeds held in the Trust Account are and will be invested only in U.S. government securities with a maturity of one hundred eighty (180) days or less or in money market funds that meet certain conditions under Rule 2a-7 The Company’s amended and restated memorandum and articles of association provide that, other than the withdrawal of interest to pay tax obligations, none of the funds held in the Trust Account will be released until the earliest of: (i) the completion of the Initial Business Combination; (ii) the redemption of any Class A ordinary shares included in the Units (the “Public Shares”) sold in the Public Offering that have been properly tendered in connection with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association to affect the substance or timing of its obligation to redeem 100% of such Public Shares if it has not consummated an Initial Business Combination within 24 months from the closing of the Public Offering; or (iii) the redemption of 100% of the Public Shares if the Company is unable to complete an Initial Business Combination within 24 months from the closing of the Public Offering. The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the Company’s public shareholders. Initial Business Combination The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Public Offering, although substantially all of the net proceeds of the Public Offering are intended to be generally applied toward consummating an Initial Business Combination. If the Company’s securities continue to be listed on the NYSE, the Initial Business Combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on income earned on the Trust Account) at the time of the agreement to enter into the Initial Business Combination. Furthermore, there is no assurance that the Company will be able to successfully effect an Initial Business Combination. The Company, after signing a definitive agreement for an Initial Business Combination, will either (i) seek shareholder approval of the Initial Business Combination at a meeting called for such purpose in connection with which shareholders may seek to redeem their shares, regardless of whether they vote for or against the Initial Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable, or (ii) provide shareholders with the opportunity to sell their Public Shares to the Company by means of a tender offer (and thereby avoid the need for a shareholder vote) for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable. However, 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. In such case, the Company would not proceed with the redemption of its Public Shares and the related Initial Business Combination, and instead may search for an alternate Initial Business Combination. The decision as to whether the Company will seek shareholder approval of the Initial Business Combination or will allow shareholders to sell their Public Shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek shareholder approval, unless a vote is required by law or under NYSE rules. If the Company seeks shareholder approval, it will complete its Initial Business Combination only if a majority of the ordinary shares voted are voted in favor of the Initial Business Combination. If the Company holds a shareholder vote or there is a tender offer for shares in connection with an Initial Business Combination, a public shareholder will have the right to redeem its shares for an amount in cash equal to its pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable. As a result, such Class A ordinary shares are classified as temporary equity upon the completion of the Public Offering, in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, “ Distinguishing Liabilities from Equity Pursuant to the Company’s amended and restated memorandum and articles of association, if the Company is unable to complete an Initial Business Combination within 24 months from the closing of the Public Offering, 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, subject to lawfully available funds therefor, redeem the Public Shares, at a per-share In the event of a liquidation, dissolution or winding up of the Company after an Initial Business Combination, the Company’s shareholders are entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class of ordinary shares, if any, having preference over the ordinary shares. The Company’s shareholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the ordinary shares, except that the Company will provide its shareholders with the opportunity to redeem their Public Shares for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account, upon the completion of the Initial Business Combination, subject to the limitations described herein. Mandatory Liquidation and Going Concern Considerations The Company only has 24 months from the closing date of the Public Offering (until December 5, 2019) to complete an Initial Business Combination. If the Company does not complete an Initial Business Combination within 24 months from the closing date of the Public Offering, 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 In the event of liquidation, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be less than the Public Offering price per Unit. As of September 30, 2019, the Company does not have sufficient liquidity to meet its future obligations. Management has determined that the Company will receive advances from the Sponsor or funds in the form of working capital loans of up to $1,500,000 from the Sponsor entity that are sufficient to fund the working capital needs of the Company until the Initial Business Combination or December 5, 2019 (See Note 4). In connection with the Company’s 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”,

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of presentation The accompanying unaudited condensed interim 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 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 September 30, 2019 and the results of operations and cash flows for the periods 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 condensed interim financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K Emerging growth company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act, and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, 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 Exchange Act of 1934, as amended) 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 Use of estimates The preparation of financial statements in conformity with GAAP 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 revenues and expenses during the reporting periods. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near-term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and c e The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. Concentration of credit risk Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times may exceed the Federal depository insurance coverage of $250,000. As of September 30, 2019 and December 31, 2018, the Company had not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Fair value of financial instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, “ Fair Value Measurements and Disclosures Income taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740, “ Income Taxes FASB ASC Topic 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 There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman Islands income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statements. Redeemable ordinary shares The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in FASB ASC Topic 480 “ Distinguishing Liabilities from Equity As discussed in Note 1, all of the 30,000,000 Public Shares contain a redemption feature which allows for the redemption of such shares under the Company’s amended and restated memorandum and articles of association. In accordance with FASB ASC Topic 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 Topic 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 securities 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, or in the absence of additional paid in capital, retained earnings. Accordingly, as of September 30, 2019 and December 31, 2018, 29,464,253 and 29,009,303, respectively, of 30,000,000 Public Shares were classified outside of permanent equity. Private p w Each whole Private Placement Warrant is exercisable for one whole Class A ordinary share at a price of $11.50 per share. A portion of the purchase price of the Private Placement Warrants has been added to the proceeds from the Public Offering to be held in the Trust Account such that at the closing of the Public Offering $300,000,000 was held in the Trust Account. If an Initial Business Combination is not completed within 24 months from the closing of the Public Offering, the proceeds from the sale of the Private Placement Warrants held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable Net income (loss) per ordinary share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “ Earnings Per Share. The Company’s condensed interim statements of operations include a presentation of net income (loss) per share for ordinary shares subject to redemption in a manner similar to the two-class Related p The Company follows FASB ASC subtopic 850-10 Pursuant to Section 850-10-20, Section 825-10-15, Subsequent e The Company evaluates subsequent events and transactions that occur after the balance sheet date for potential recognition or disclosure. Any material events that occur between the balance sheet date and the date that the financial statements were issued are disclosed as subsequent events, while the financial statements are adjusted to reflect any conditions that existed at the balance sheet date. Recent a p The Company’s management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.

Related Party Transactions [Abstract]
Related Party Transactions	Note 4. Related Party Transactions Founder Shares In September 2017, the Sponsor entered into a Securities Subscription Agreement, for the purchase of 8,625,000 Class B ordinary shares by the Sponsor (the “Founder Shares”) in exchange for a capital contribution of $25,000, or approximately $0.003 per share. As used herein, unless the context otherwise requires, “Founder Shares” shall be deemed to include the Class A ordinary shares issuable upon conversion thereof. The Founder Shares are identical to the Public Shares except that the Founder Shares are Class B ordinary shares which automatically convert into Class A ordinary shares at the time of the Company’s Initial Business Combination and are subject to certain transfer restrictions, as described in more detail below. The Sponsor agreed, subject to limited exceptions, not to transfer, assign or sell any of its Founder Shares until the earliest of (a) one year after the completion of the Initial Business Combination or (b) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction after an Initial Business Combination that results in all of the Company’s shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property. Any permitted transferees will be subject to the same restrictions and other agreements of the Sponsor with respect to any Founder Shares. Notwithstanding the foregoing, if the closing price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading The Sponsor agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the Initial Business Combination. In January 2018, the underwriters’ over-allotment option expired and as a result the Sponsor forfeited 1,125,000 Class B ordinary shares. Registration Rights The holders of Founder Shares, Private Placement Warrants and Warrants that may be issued upon conversion of working capital loans, if any, will be entitled to registration rights (in the case of the Founder Shares, only after conversion of such shares to Class A ordinary shares) pursuant to a registration rights agreement entered into in connection with the consummation of the Public Offering. These holders will be entitled to certain demand and “piggyback” registration rights. However, the registration rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lock-up Forward Purchase Agreement On December 5, 2017, the Company entered into a forward purchase agreement (the “Forward Purchase Agreement”) pursuant to which the Sponsor agreed to purchase Units consisting of up to 25,000,000 Class A ordinary shares, plus up to 8,333,333 warrants (the “Forward Purchase Warrants”), for an aggregate purchase price of up to $250,000,000 or $10.00 per unit (collectively, the “Forward Purchase Units”). The Forward Purchase Warrants have the same terms as the Private Placement Warrants. The obligations under the Forward Purchase Agreement do not depend on whether any public shareholders elect to redeem their shares in connection with the Initial Business Combination and provide the Company with a minimum funding level for the Initial Business Combination. Additionally, the obligations of the Sponsor to purchase the Forward Purchase Units are subject to termination prior to the closing of the sale of such Units by mutual written consent of the Company and the Sponsor, or automatically: (i) if the Initial Business Combination is not consummated within 24 months from the closing of the Public Offering, unless extended up to a maximum of sixty (60) days in accordance with the amended and restated memorandum and articles of association; or (ii) if the Sponsor or the Company become subject to any voluntary or involuntary petition under the United States federal bankruptcy laws or any state insolvency law, in each case which is not withdrawn within sixty (60) days after being filed, or a receiver, fiscal agent or similar officer is appointed by a court for business or property of the Sponsor or the Company in each case which is not removed, withdrawn or terminated within sixty (60) days after such appointment. In addition, the obligations of the Sponsor to purchase the Forward Purchase Units are subject to fulfillment of customary closing conditions, including that the Initial Business Combination must be consummated substantially concurrently with the purchase of the Forward Purchase Units. Promissory Note — Related Party The Sponsor agreed to loan the Company up to $300,000 to be used for the payment of costs related to the Public Offering. The loan was non-interest Advances from Related Parties An Affiliate of the Company’s executive officers and the Sponsor paid certain administrative expenses and offering costs on behalf of the Company. These advances were due on demand and were non-interest A A Administrative Service Fee The Company agreed, commencing on the effective date of the Public Offering through the earlier of the Company’s consummation of an Initial Business Combination and its liquidation, to pay an Affiliate of the Sponsor a monthly fee of up to $20,000 for office space, and secretarial and administrative services. The Company incurred $60,000 for such expenses under the administrative services agreement for the three months ended September 30, 2019 and 2018. The Company incurred $180,000 for such expenses under the administrative services agreement for the nine months ended September 30, 2019 and 2018.

Shareholders’ Equity Class A Ordinary Shares Class B Ordinary Shares as-converted Holders of Class A ordinary shares and Class B ordinary shares will vote together as a single class on all matters submitted to a vote of shareholders except as required by law. Preference Shares Warrants The Private Placement Warrants are identical to the Warrants, except that the Private Placement Warrants and the Class A ordinary shares issuable upon exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of an Initial Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be non-redeemable The Company may call the Warrants for redemption (except with respect to the Private Placement Warrants): • in whole and not in part; • at a price of $0.01 per warrant; • upon a minimum of 30 days’ prior written notice of redemption; and • if, and only if, the last reported closing price of the ordinary shares equals or exceeds $18.00 per share for any 20 trading days within a 30-trading If the Company calls the Warrants for redemption, management will have the option to require all holders that wish to exercise the Warrants to do so on a “cashless basis,” as described in the warrant agreement, the exercise price and number of Class A ordinary shares issuable upon exercise of the Warrants may be adjusted in certain circumstances including in the event of a share dividend, or recapitalization, reorganization, merger or consolidation. However, the Warrants will not be adjusted for issuance of Class A ordinary shares at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the warrant shares. If the Company is unable to complete an Initial Business Combination within 24 months from the consummation of the Public Offering and the Company liquidates the funds held in the Trust Account, holders of Warrants will not receive any of such funds with respect to their Warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such Warrants. Accordingly, the Warrants may expire worthless.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accompanying unaudited condensed interim 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 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 September 30, 2019 and the results of operations and cash flows for the periods 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 condensed interim financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K
Emerging growth company	Emerging growth company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act, and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, 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 Exchange Act of 1934, as amended) 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
Use of estimates	Use of estimates The preparation of financial statements in conformity with GAAP 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 revenues and expenses during the reporting periods. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near-term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.
Cash and cash equivalents	Cash and c e The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents.
Concentration of credit risk	Concentration of credit risk Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times may exceed the Federal depository insurance coverage of $250,000. As of September 30, 2019 and December 31, 2018, the Company had not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.
Fair value of financial instruments	Fair value of financial instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, “ Fair Value Measurements and Disclosures
Income taxes	Income taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740, “ Income Taxes FASB ASC Topic 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 There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman Islands income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statements.
Redeemable ordinary shares	Redeemable ordinary shares The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in FASB ASC Topic 480 “ Distinguishing Liabilities from Equity As discussed in Note 1, all of the 30,000,000 Public Shares contain a redemption feature which allows for the redemption of such shares under the Company’s amended and restated memorandum and articles of association. In accordance with FASB ASC Topic 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 Topic 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 securities 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, or in the absence of additional paid in capital, retained earnings. Accordingly, as of September 30, 2019 and December 31, 2018, 29,464,253 and 29,009,303, respectively, of 30,000,000 Public Shares were classified outside of permanent equity.
Private placement warrants	Private p w Each whole Private Placement Warrant is exercisable for one whole Class A ordinary share at a price of $11.50 per share. A portion of the purchase price of the Private Placement Warrants has been added to the proceeds from the Public Offering to be held in the Trust Account such that at the closing of the Public Offering $300,000,000 was held in the Trust Account. If an Initial Business Combination is not completed within 24 months from the closing of the Public Offering, the proceeds from the sale of the Private Placement Warrants held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable
Net income (loss) per ordinary share	Net income (loss) per ordinary share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “ Earnings Per Share. The Company’s condensed interim statements of operations include a presentation of net income (loss) per share for ordinary shares subject to redemption in a manner similar to the two-class
Related parties	Related p The Company follows FASB ASC subtopic 850-10 Pursuant to Section 850-10-20, Section 825-10-15,
Subsequent events	Subsequent e The Company evaluates subsequent events and transactions that occur after the balance sheet date for potential recognition or disclosure. Any material events that occur between the balance sheet date and the date that the financial statements were issued are disclosed as subsequent events, while the financial statements are adjusted to reflect any conditions that existed at the balance sheet date.
Recent accounting pronouncements	Recent a p The Company’s management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.
