Equity [Abstract]
Stockholders' Equity	12. STOCKHOLDERS’ EQUITY As of September 30, 2018, 93,234,871 shares of common stock were issued on the accompanying unaudited condensed consolidated balance sheet, which excludes 1,184,400 unvested shares of common stock and 1,896,150 unvested restricted stock units held by certain participants in the Company’s equity compensation plans (see Note 11–Equity-Based Compensation) and includes 6,519,773 shares of treasury stock held by the Company. Dividends In 2016, the Board suspended the Company’s then existing quarterly dividend policy to allow greater flexibility to deploy capital to opportunities that offer the greatest long term returns to shareholders, such as, but not limited to, investments in new attractions, debt repayments or share repurchases. As of September 30, 2018, the Company had approximately $0.1 million recorded as dividends payable in the accompanying unaudited condensed consolidated balance sheet related to unvested time restricted shares and unvested performance restricted shares with a performance condition considered probable of being achieved. These shares, which were granted prior to the dividend suspension, carry dividend rights and therefore the dividends accumulate and will be paid as the shares vest in accordance with the underlying equity compensation grants. These dividend rights will be forfeited if the shares do not vest. Share Repurchase Program The Board has authorized the repurchase of up to $250.0 million of the Company’s common stock (the “Share Repurchase Program”). Under the Share Repurchase Program, the Company is authorized to repurchase shares through open market purchases, privately-negotiated transactions or otherwise in accordance with applicable federal securities laws, including through Rule 10b5-1 trading plans and under Rule 10b-18 of the Exchange Act. The Share Repurchase Program has no time limit and may be suspended or discontinued completely at any time. The number of shares to be purchased and the timing of purchases will be based on the level of the Company’s cash balances, general business and market conditions, and other factors, including legal requirements, debt covenant restrictions and alternative investment opportunities. The Company has remaining authorization for up to $190.0 million for future repurchases under the Share Repurchase Program as of September 30, 2018. There were no share repurchases during the three and nine months ended September 30, 2018 and 2017.
