Equity [Abstract]
Equity	Equity Common Stock The authorized common stock of the Company consists of 300,000,000 shares. Holders of the Company’s common stock are entitled to one vote for each share of common stock. As of June 30, 2016, there were 89,222,418 shares of common stock issued and outstanding and warrants to purchase 25,012,500 shares of common stock at a strike price of $11.50. Prior to the completion of the Business Combination, the Company had 62,531,250 shares of common stock issued and outstanding, consisting of 50,025,000 shares originally sold as part of units issued in the Company’s IPO, consummated on June 11, 2014, and 12,506,250 shares of Founder Shares that were issued to Sponsor prior to the IPO. All of the 50,025,000 shares of common stock sold as part of the units in the IPO contained a redemption feature which allowed for the redemption of such shares. These redemption provisions generally required the Company to classify these shares outside of permanent equity, except for certain provisions related to ordinary liquidations involving the redemption and liquidation of all of the Company’s equity instruments that allowed the Company to classify a certain amount related to these shares as permanent equity at each reporting period. At March 31, 2016, 47,512,924 of the 50,025,000 public shares with a value of $475.2 million were classified outside of permanent equity at their redemption value. On June 9, 2016, in connection with the completion of the Business Combination, 47,512,924 shares were reclassified into equity and 29,793,320 shares were redeemed at $10.02 per share. Additionally, the Company issued (i) 27,673,604 new shares of common stock at $10.00 per share to the Selling Equityholders as consideration, (ii) 23,492,306 new shares of common stock at a price of $10.00 per share in private placements with eligible purchasers, (iii) 3,078,578 new shares of common stock to settle the payment of an aggregate of $30.8 million in fees and disbursements outstanding and due to certain of WLRH’s advisors in connection with services and work performed by the advisors, including shares issued to pay the liability of $18.3 million for deferred underwriting fees due upon the completion of a Business Combination from the original IPO and (iv) 2,240,000 new shares of common stock in exchange for 22,400,000 warrants to purchase shares of common stock privately placed to Sponsor at the time of the IPO. In connection with the completion of the Business Combination, the Sponsor (on behalf of the Company) transferred 30,000 original Founder Shares to the Company’s prior independent directors (“Director Founder Shares”) in connection with services previously rendered to the Company and 3,554,240 Founder Shares with a fair value of $30.2 million to the Selling Equityholders. The fair value of the Founder Shares transferred to the Company’s prior independent directors was recorded as an equity contribution and a transaction related costs for the three months ended June 30, 2016. The fair value of the Founder Shares transferred to the directors and Selling Equityholders was estimated using a Monte Carlo simulation model. The 3,554,240 of Founder Shares that were transferred to the Selling Equityholders was a component of the Business Combination purchase consideration and was recorded by the Company as an equity contribution and included in the purchase consideration. See Note 3. In connection with the consummation of the Business Combination, the Founder Shares other than the Director Founder Shares became subject to forfeiture on the tenth anniversary of the Closing Date unless: •with respect to 50% of such Founder Shares, the last sale price of the Company’s common stock as quoted on NASDAQ equals or exceeds $12.50 per share (as adjusted for stock splits, dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 trading day period; and •with respect to the remaining 50% of such Founder Shares, the last sale price of the Company’s common stock equals or exceeds $15.00 per share (as adjusted for stock splits, dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 trading day period; or •the post-combination company completes a liquidation, merger, stock exchange or other similar transaction that results in all or substantially all of its shareholders having the right to exchange their shares of common stock for consideration in cash, securities or other property or any transaction involving a consolidation, merger, proxy contest, tender offer or similar transaction in which the post-combination company is the surviving entity which results in a change in the majority of the Company’s board of directors or management team or the Company’s post-combination shareholders immediately prior to such transaction ceasing to own a majority of the surviving entity immediately after such transaction. Such Founder Shares other than the Director Founder Shares will not participate in dividends or other distributions with respect to the shares prior to these targets being met, whereupon the Founder Shares shall be entitled to all dividends and distributions paid on the common stock after the Business Combination as if they had been holders of record entitled to receive distributions on the applicable record date. Preferred Stock The authorized preferred stock of the Company consists of 1,000,000 shares. As of June 30, 2016, there were no shares of preferred stock issued and outstanding. The Company’s amended and restated certificate of incorporation provides that shares of preferred stock may be issued from time to time in one or more series. The Board of Directors is 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 is able, without shareholder approval, to issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the Common Stock and could have anti-takeover effects. The ability of the Board of Directors to issue preferred stock without shareholder approval could have the effect of delaying, deferring or preventing a change of control of the Company. Offering Costs Offering costs associated with the IPO, consummated on June 11, 2014, consisting principally of professional and registration fees incurred of $28.5 million (including $27.5 million in underwriters’ fees) were charged to shareholders’ equity upon the completion of the IPO. The Company paid upfront underwriting fees of approximately 1.84% ($9.2 million) of the per unit offering price to the underwriters at the close of the IPO with an additional fee of 3.66% ($18.3 million) of the gross offering proceeds payable upon the Company’s completion of a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination. These deferred underwriting costs were paid with the issuance of common stock in connection with the Business Combination.
