Mar. 31, 2018
Equity [Abstract]
Equity and Stock-Based Compensation	Equity and Stock-Based Compensation Dividends—Common stock dividends declared for the three months ended March 31, 2018 and 2017, were $5.2 million and $5.1 million, respectively. Performance Stock Units—The compensation committee of the board of directors of the Company approves grants of PSUs to certain executive officers from time to time. The award agreements provide for the grant of a target number of PSUs that will be settled in shares of common stock of the Company, if and when the applicable vesting criteria have been achieved following the end of the performance and service period, generally, three years from the issuance date. The target number of PSUs may be adjusted from 0% to 200% based on achievement of a specified relative total stockholder return based on the formula determined by the Company’s Compensation Committee on the grant date. The performance criteria for the PSUs are based on market conditions under the relevant literature, and the PSUs were granted to non-employees. At March 31, 2018, the outstanding PSUs had a fair value of $2.6 million. We recorded compensation expense in the amount of $1.6 million and a credit of $800,000 due to lower fair values of the PSUs for the three months ended March 31, 2018 and 2017, respectively. During the three months ended March 31, 2018, approximately $1.6 million of the compensation expense was related to the accelerated vesting of PSUs granted to one of our executive officers upon his passing, in accordance with the terms of the awards. These amounts are included in “advisory services fee” on our condensed consolidated statements of operations. As of March 31, 2018, we had unamortized compensation expense of $2.4 million related to PSUs which is expected to be recognized over a period of 2.8 years, subject to future mark to market adjustments. Restricted Stock Units—Stock-based compensation expense of $825,000 and $118,000 was recognized for the three months ended March 31, 2018 and 2017, respectively, in connection with restricted stock units awarded to employees of Ashford LLC and is included in “advisory services fee” on our condensed consolidated statements of operations. During the three months ended March 31, 2018, approximately $640,000 of the compensation expense was related to the accelerated vesting of equity awards granted to one of our executive officers upon his passing, in accordance with the terms of the awards. There were also restricted stock units granted to certain employees of Remington Lodging, and the associated expenses are recorded as a component of “management fees” on our condensed consolidated statements of operations. For the three months ended March 31, 2018, expense related to such grants was $46,000. For the three months ended March 31, 2017, expense related to such grants was immaterial. In addition, stock-based compensation expense of $0 and $18,000 was recognized for the three months ended March 31, 2018 and 2017, respectively, in connection with common stock issued to our independent directors, which vested immediately, and is included in “corporate general and administrative” expense on our condensed consolidated statements of operations. At March 31, 2018, the outstanding restricted shares had a fair value of $5.3 million. At March 31, 2018, the unamortized cost of the unvested shares of restricted stock was $4.6 million, which will be expensed over a period of 3.6 years, subject to future mark to market adjustments, and have vesting dates between April 2018 and November 2021. Stock Repurchases—On December 5, 2017, our board of directors reapproved the stock repurchase program pursuant to which the board of directors granted a repurchase authorization to acquire shares of the Company’s common stock, par value $0.01 per share having an aggregate value of up to $50 million. The board of directors’ authorization replaced any previous repurchase authorizations. No shares were repurchased during the three months ended March 31, 2018 and 2017, pursuant to this authorization. As of March 31, 2018, we have purchased a cumulative 4.3 million shares of our common stock, for approximately $63.2 million, since the program’s inception on November 4, 2014. At-the-Market Equity Distribution Program—On December 11, 2017, the Company established an “at-the-market” equity distribution program pursuant to which it may, from time to time, sell shares of its Common Stock having an aggregate offering price of up to $50 million. As of March 31, 2018, no shares of our common stock have been sold under this program. Noncontrolling Interest in Consolidated Entities—A partner had noncontrolling ownership interests of 25% in two hotel properties with a total carrying value of $(4.8) million at both March 31, 2018 and December 31, 2017, respectively. Noncontrolling interests in consolidated entities were allocated a net loss of $42,000 and $21,000 for the three months ended March 31, 2018 and 2017, respectively.
