Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business Operations	1. Organization and Business Operations Organization and General Saban Capital Acquisition Corp. (the “Company”) was incorporated in the Cayman Islands on March 15, 2016. 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 (the “Business Combination”). 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”). The Company’s sponsor is Saban Sponsor LLC, a Delaware limited liability company (the “Sponsor”). At December 31, 2017, the Company had not commenced any significant operations. All activity for the period from March 15, 2016 (“Inception”) through December 31, 2017 relates to the Company’s formation and activities related to the initial public offering of Units (as defined below), each consisting of one of the Company’s Class A ordinary shares and one half of one warrant where each whole warrant entitles the holder to purchase one Class A ordinary share (the “Public Offering”). The Company will not generate any operating revenues until after completion of the Business Combination, at the earliest. The Company will generate non-operating st Cash Cash consisted of cash held at two U.S. financial institutions, and is subject to credit risk to the extent the balance exceeds federal deposit insurance limits. Financing The registration statement for the Company’s Public Offering was declared effective by the United States Securities and Exchange Commission (the “SEC”) on September 15, 2016. The Public Offering closed on September 21, 2016 (the “Close Date”). The Company’s Sponsor purchased an aggregate of 7,000,000 warrants at a purchase price of $1.00 per warrant, or $7,000,000 in the aggregate, in a private placement at the Close Date (the “Private Placement”). The warrants are included in additional paid-in The Company intends to finance a Business Combination with a portion of proceeds from its $250,000,000 Public Offering and $7,000,000 Private Placement (see Note 3). At the Close Date, proceeds from the Public Offering of $250,000,000, net of underwriting discounts of $5,000,000, and $5,000,000 of the Private Placement proceeds, 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 As of September 21, 2016, the net proceeds from the Public Offering and a portion of the Private Placement Proceeds were deposited in the Trust Account. The Trust Account may be invested only in U.S. government treasury bills with a maturity of one hundred and eighty (180) days or less or in money market funds investing solely in United States Treasuries and meeting certain conditions under Rule 2a-7 3a-1 2a-7. Funds will remain in the Trust Account except for the withdrawal of interest to pay taxes, if any, until the earliest of (i) the completion of the Business Combination, (ii) the redemption of any Public Shares (as defined below) properly tendered in connection with a shareholder vote to amend the amended and restated memorandum and articles of association to modify the substance and timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete its Business Combination within 24 months from the Close Date, or (iii) the redemption of all of the Company’s Public Shares if it is unable to complete the Business Combination within 24 months from the Close Date, subject to applicable law. The remaining proceeds outside the Trust Account may be used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses. 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 a Business Combination with (or acquisition of) a Target Business. As used herein, the “Target Business” must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account, net of any deferred underwriting commissions and taxes payable on interest earned, at the time of the Company signing a definitive agreement to proceed with a Business Combination. Furthermore, there is no assurance that the Company will be able to successfully effect a Business Combination. The Company, after signing a definitive agreement for a Business Combination, will either (i) seek shareholder approval of the 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 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 Business Combination, including interest but less taxes payable, or (ii) provide shareholders with the opportunity to sell their 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 commencement of the tender offer, including interest but less taxes payable. The decision as to whether the Company will seek shareholder approval of the Business Combination or will allow shareholders to sell their 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 NASDAQ rules. If the Company seeks shareholder approval, it will complete its Business Combination only if a majority of the issued and outstanding ordinary shares voted are voted in favor of the Business Combination. 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 Business Combination, and instead may search for an alternate Business Combination. If the Company holds a shareholder vote or there is a tender offer for its Public Shares in connection with a Business Combination, a public shareholder will have the right to redeem its Public 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 Business Combination, including interest but less taxes payable. As a result, such Public Shares are recorded at their redemption amount and classified as temporary equity in accordance with Accounting Standards Codification (“ASC”) 480, “Distinguishing Liabilities from Equity” (“ASC 480”) except for the portion of Public Shares required to maintain net tangible assets at least $5,000,001. That portion of Public Shares is classified as permanent shareholder’s equity. The Company has 24 months after the Close Date to complete a Business Combination. If the Company does not complete a Business Combination within this time period, it shall (i) cease all operations except for the purposes 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, net of taxes payable (less up to $50,000 of such net interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the public shareholders’ rights as owners of Class A ordinary shares (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 remaining shareholders and the Company’s 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. The Initial Shareholders (as defined below) have entered into a letter agreement with the Company, pursuant to which they have waived their rights to liquidating distributions from the Trust Account with respect to their Founder Shares if the Company fails to complete a Business Combination within 24 months after the Close Date. However, if the Initial Shareholders acquire Public Shares after the Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete the Business Combination within 24 months after the Close Date. If the Company fails to complete a Business Combination within 24 months after the Close Date, the resulting redemption of the Company’s Class A ordinary shares will reduce the book value per share for the Founder Shares held by the Initial Shareholders, who would be the only remaining shareholders after such a redemption. If the Company completes a Business Combination within 24 months after the Close Date, the funds in the Trust Account will be used to pay for the Business Combination, redemptions of Class A ordinary shares, if any, the deferred underwriting commission of $8,750,000 and accrued expenses related to the Business Combination. Any funds remaining will be made available to the Company to provide working capital to finance the Company’s business operations.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. 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 Company’s financial position at December 31, 2017 and the results of operations and cash flows for the years presented. 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 Exchange Act, as amended (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 Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in financial institutions 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 values of the Company’s assets and liabilities which qualify as financial instruments under ASC 820, “Fair Value Measurements and Disclosures,” approximate the carrying amounts represented on the balance sheet. Redeemable Ordinary Shares All 25,000,000 Class A ordinary shares sold as part of the Units in the Public Offering contain a redemption feature as discussed in Note 1. In accordance with 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 ASC 480. Although the Company did not specify a maximum redemption threshold, its charter provides that in no event will it redeem its Class A ordinary shares in an amount that would cause its net tangible assets to fall below $5,000,001. Accordingly, at December 31, 2017, 23,812,549 of the Company’s 25,000,000 Class A ordinary shares were classified outside of permanent equity at their redemption value. Net Income/(Loss) per Ordinary Share The Company has two classes of ordinary shares, which are referred to as Class A ordinary shares and Class F ordinary shares. The Company’s public shareholders have the opportunity to redeem their shares upon the completion of the Business Combination at a per share price that is equal to the aggregate amount then on deposit in the Trust Account including interest, divided by the number of then outstanding Public Shares, subject to certain limitations. Accordingly, the Company uses the two-class two-class For the Year Ended For the Period from Class A Class F Class A Class F Basic and diluted net loss per share: Numerator: Allocation of net income (loss) $ 1,057,100 $ (142,118 ) $ (84,794 ) $ (176,859 ) Denominator: Weighted-average shares outstanding 25,000,000 6,247,006 8,677,500 5,670,000 Basic and diluted net loss per share $ 0.04 $ (0.02 ) $ (0.01 ) $ (0.03 ) Use of Estimates The preparation of the Company’s balance sheet in conformity with U.S. 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 balance sheet. Actual results could differ from those estimates. Offering Costs The Company complies with the requirements of ASC 340-10-S99-1 paid-in Income Taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes” (“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement 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. 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 Exempted companies are Cayman Islands companies wishing to conduct business outside the Cayman Islands and, as such, are exempted from complying with certain provisions of the Companies Law. As an exempted company, the Company has applied for and received a tax exemption undertaking from the Cayman Islands government that, in accordance with Section 6 of the Tax Concessions Law (2011 Revision) of the Cayman Islands, for a period of 20 years from the date of the undertaking, no law which is enacted in the Cayman Islands imposing any tax to be levied on profits, income, gains or appreciations shall apply to the Company or its operations and, in addition, that no tax to be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax shall be payable (i) on or in respect of the shares or other obligations of the Company or (ii) by way of the withholding in whole or in part of a payment of dividend or other distribution of income or capital by the Company to its shareholders or a payment of principal or interest or other sums due under a debenture or other obligation of the Company. Consequently, income taxes have not been reflected in the Financial Statements. Recent Accounting Pronouncements 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.

Public Offering

Public Offering	12 Months Ended

Text Block [Abstract]
Public Offering	3. Public Offering In its Public Offering, the Company sold 25,000,000 Units at a price of $10.00 per Unit (the “Units”). Each Unit consists of one of the Company’s Class A ordinary shares, $0.0001 par value per share (each, a “Public Share”), and one half of one warrant (“Warrant”). Each whole warrant entitles the holder thereof to purchase one Class A ordinary share at a price of $11.50 per share. Warrants may be exercised only for a whole number of Class A ordinary shares; no fractional shares will be issued upon exercise of the Warrants. Each Warrant will become exercisable on the later of 30 days after the completion of the initial Business Combination or 12 months after the Close Date, and will expire after the earlier of five years after the completion of the initial Business Combination, or upon redemption or liquidation. Alternatively, if the Company does not complete a Business Combination within 24 months after the Close Date, the Warrants will expire worthless at the end of such period. If the Company is unable to deliver registered Class A ordinary shares to the holder upon exercise of Warrants issued in connection with the 25,000,000 Units during the exercise period, the Warrants will expire worthless, except to the extent that they may be exercised on a cashless basis in the circumstances described in the Warrant agreement. Once the Warrants become exercisable, the Company may redeem the outstanding Warrants in whole, but not in part, at a price of $0.01 per Warrant upon a minimum of 30 days’ prior written notice of redemption, and only in the event that the last sale price of the Company’s Public Shares equals or exceeds $18.00 (subject to adjustments) per share for any 20 trading days within the 30-trading The Company paid an underwriting discount of 2.00% of the gross proceeds of the Public Offering, or $5,000,000, to the underwriters at the Close Date, with an additional fee (the “Deferred Discount”) of 3.50% of the gross proceeds of the Public Offering, or $8,750,000, payable upon the Company’s completion of a Business Combination. The Deferred Discount will become payable to the underwriters from the amounts held in the Trust Account solely in the event the Company completes a Business Combination. The underwriters are not entitled to receive any of the interest earned on Trust Account funds that would be used to pay the Deferred Discount. The Deferred Discount is recorded as deferred underwriter compensation at the Company’s balance sheet.

Related Party Transactions Founder Shares On April 11, 2016, the Company’s Sponsor purchased 5,750,000 Class F ordinary shares (“Founder Shares”) for $25,000, or approximately $0.004 per share. In August 2016, the Company repurchased 99,000 Founder Shares from the Sponsor at their original per share issuance price and subsequently issued such number of Founder Shares pursuant to The 2016 Share Award Plan of the Company for the same per share price to certain individuals who will assist in the evaluation of investment opportunities, including 10,000 Founder Shares to Adam Chesnoff, the Company’s Director, President and Chief Executive Officer, 8,000 Founder Shares to Niveen Tadros, the Company’s Executive Vice President and General Counsel, 6,000 Founder Shares to Fred Gluckman, the Company’s Executive Vice President and Chief Financial Officer, and 4,000 Founder Shares to Philip Han, the Company’s Executive Vice President and Chief Investment Officer. In September 2016, the Company’s Sponsor transferred 30,000 Founder Shares to each of the Company’s independent director nominees at their original per share issue price (together with the Sponsor and the other individuals that received founder shares, the “Initial Shareholders). On September 15, 2016, we effected a pro rata share capitalization resulting in an increase in the total number of Founder Shares outstanding from 5,750,000 to 6,250,000 in order to maintain the ownership of Founder Shares by our Initial Shareholders at 20% of our issued and outstanding shares upon consummation of the Public Offering. Following the Public Offering and the pro rata share capitalization, our Sponsor held 6,044,570 Founder Shares, each of our three independent directors owned 32,610 Founder Shares, and the other individuals, including our executive officers, held 107,600 Founder Shares. On March 16, 2017, concurrent with Mr. Bruce Rosenblum’s resignation from our board of directors, the Company acquired 25,100 Founders Shares from Mr. Rosenblum and concurrent therewith, in connection with Mr. Casey Wasserman’s appointment to the board of directors, the Company re-issued The Founder Shares are identical to the Public Shares, and holders of Founder Shares have the same shareholder rights as public shareholders, except that: (i) the Founder Shares are subject to certain transfer restrictions; (ii) the Initial Shareholders have entered into a letter agreement with the Company, pursuant to which they have agreed (a) to waive their redemption rights with respect to their Founder Shares and the Public Shares in connection with the completion of a Business Combination and (b) to waive their rights to liquidating distributions from the Trust Account with respect to their Founder Shares if the Company fails to complete a Business Combination within 24 months from the closing of the Public Offering, although they will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares they hold if the Company fails to complete a Business Combination within such time period; (iii) the Founder Shares are automatically convertible into Class A ordinary shares at the time of a Business Combination on a one-for-one basis, subject to adjustment pursuant to certain anti-dilution rights, as described in the Company’s Articles; and (iv) the Founder Shares are subject to registration rights. If the Company submits a Business Combination to its public shareholders for a vote, the Initial Shareholders have agreed to vote their Founder Shares and any public shares purchased during or after the Public Offering in favor of the Business Combination. Permitted transferees of the Initial Shareholders will be subject to the same obligations of the Initial Shareholders. Private Placement Warrants Simultaneously with the consummation of the Public Offering, the Sponsor purchased 7,000,000 warrants at a price of $1.00 per warrant, or $7,000,000 in the aggregate, in a Private Placement (the “Private Placement Warrants”). Each Private Placement Warrant entitles the holder to purchase one Class A ordinary share for $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants were placed in the Trust Account. The Private Placement Warrants may not be redeemed by the Company so long as they are held by the Sponsor. If any Private Placement Warrants are held by holders other than the Sponsor or certain permitted transferees, such Private Placement Warrants will be redeemable and exercisable by the holders on the same basis as the Warrants included in the Units sold under the Public Offering. The Sponsor has the option to exercise the Private Placement Warrants on a cashless basis. The Private Placement Warrants (including the Class A ordinary shares issuable upon exercise of the Private Placement Warrants) may not, subject to certain limited exceptions, be transferred, assigned or sold by it until 30 days after the completion of the Business Combination. If the Company does not complete a Business Combination within 24 months after the Close Date, the proceeds of the sale of the Private Placement Warrants held in the Trust Account will be used to fund the redemption of the Company’s Public Shares (subject to the requirements of applicable law), and the Private Placement Warrants will expire worthless. Registration Rights Holders of the Founder Shares and Private Placement Warrants and warrants that may be issued upon conversion of working capital loans (and any ordinary shares issuable upon the exercise of the Private Placement Warrants or warrants issued upon conversion of the working capital loans), have registration rights pursuant to a registration rights agreement signed on the Close Date requiring the Company to register such securities for resale (in the case of the Founder Shares, only after conversion to the Company’s Class A ordinary shares). The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities, Class A ordinary shares underlying the Private Placement Warrants and Class F ordinary shares. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed by the Company subsequent to its completion of a Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. 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 period, which occurs: (i) in the case of the Founder Shares, on the earlier of (A) one year after the completion of a Business Combination or (B) if, subsequent to a Business Combination, (x) the last reported sale price of the Class A ordinary 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 Related Party Notes Between Inception and the Close Date, the Sponsor loaned the Company $250,000 in unsecured promissory notes. The funds were used to pay up front expenses associated with the Public Offering. These notes were non-interest bearing and were repaid by netting against proceeds received from the Sponsor at the Close Date. Due to Related Party Saban Capital Group, Inc. is an affiliate of the Sponsor which advanced various costs on behalf of the Company. Total related party advances amounted to $32,239 for the year ended December 31, 2017 and were reported as general and administrative expenses. As of December 31, 2017, the amount due to related party was $3,502. Total related party advances amounted to $66,461 and the amount due were $4,849 for the period March 15, 2016 (inception) through December 31, 2016 and were reported as deferred offering costs and general administrative expenses. Administrative Service Agreement Effective September 15, 2016, the Company entered into an agreement to pay monthly expenses of $10,000 for office space, administrative services and support services to an affiliate of the Company’s Sponsor. The agreement terminates upon the earlier of the completion of a Business Combination or the liquidation of the Company. For the year ended December 31, 2017, the Company incurred expenses of $120,000 under this agreement. For the period March 15, 2016 (inception) through December 31, 2016, the Company incurred expenses of $35,000.

Summary of Significant Accoun17

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. 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 Company’s financial position at December 31, 2017 and the results of operations and cash flows for the years presented.
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 Securities Exchange Act, as amended (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
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 financial institutions 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 values of the Company’s assets and liabilities which qualify as financial instruments under ASC 820, “Fair Value Measurements and Disclosures,” approximate the carrying amounts represented on the balance sheet.
Redeemable Ordinary Shares	Redeemable Ordinary Shares All 25,000,000 Class A ordinary shares sold as part of the Units in the Public Offering contain a redemption feature as discussed in Note 1. In accordance with 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 ASC 480. Although the Company did not specify a maximum redemption threshold, its charter provides that in no event will it redeem its Class A ordinary shares in an amount that would cause its net tangible assets to fall below $5,000,001. Accordingly, at December 31, 2017, 23,812,549 of the Company’s 25,000,000 Class A ordinary shares were classified outside of permanent equity at their redemption value.
Net Income/(Loss) per Ordinary Share	Net Income/(Loss) per Ordinary Share The Company has two classes of ordinary shares, which are referred to as Class A ordinary shares and Class F ordinary shares. The Company’s public shareholders have the opportunity to redeem their shares upon the completion of the Business Combination at a per share price that is equal to the aggregate amount then on deposit in the Trust Account including interest, divided by the number of then outstanding Public Shares, subject to certain limitations. Accordingly, the Company uses the two-class two-class For the Year Ended For the Period from Class A Class F Class A Class F Basic and diluted net loss per share: Numerator: Allocation of net income (loss) $ 1,057,100 $ (142,118 ) $ (84,794 ) $ (176,859 ) Denominator: Weighted-average shares outstanding 25,000,000 6,247,006 8,677,500 5,670,000 Basic and diluted net loss per share $ 0.04 $ (0.02 ) $ (0.01 ) $ (0.03 )
Use of Estimates	Use of Estimates The preparation of the Company’s balance sheet in conformity with U.S. 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 balance sheet. Actual results could differ from those estimates.
Offering Costs	Offering Costs The Company complies with the requirements of ASC 340-10-S99-1 paid-in
Income Taxes	Income Taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes” (“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement 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. 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 Exempted companies are Cayman Islands companies wishing to conduct business outside the Cayman Islands and, as such, are exempted from complying with certain provisions of the Companies Law. As an exempted company, the Company has applied for and received a tax exemption undertaking from the Cayman Islands government that, in accordance with Section 6 of the Tax Concessions Law (2011 Revision) of the Cayman Islands, for a period of 20 years from the date of the undertaking, no law which is enacted in the Cayman Islands imposing any tax to be levied on profits, income, gains or appreciations shall apply to the Company or its operations and, in addition, that no tax to be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax shall be payable (i) on or in respect of the shares or other obligations of the Company or (ii) by way of the withholding in whole or in part of a payment of dividend or other distribution of income or capital by the Company to its shareholders or a payment of principal or interest or other sums due under a debenture or other obligation of the Company. Consequently, income taxes have not been reflected in the Financial Statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements 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.
