Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company’s 2006 Stock Incentive Plan, as amended and restated in April 2015 (the “2006 Plan”), authorizes the Company to issue up to 3,500,000 shares of common stock to employees, non-employee directors and consultants pursuant to awards of stock options, stock appreciation rights, restricted stock, in payment of performance shares or other stock-based awards. The Company amended the 2006 Plan to increase the aggregate number of shares of common stock issuable under the 2006 Plan by 1,000,000 shares to a total of 4,500,000 in May 2016, and by 2,000,000 shares to a total of 6,500,000 in May 2017. Under the 2006 Plan, stock options must be granted at a price not less than the fair market value of the stock on the date the option is granted, generally are not subject to re-pricing, and will not be exercisable more than ten years after the date of grant. Options granted under the 2006 Plan generally qualify as “non-qualified stock options” under the U.S. Internal Revenue Code. As of March 31, 2018, there were 2,040,831 shares available to be issued under the 2006 Plan. At March 31, 2018, the Company had 37,007 stock options outstanding and 1,363,917 shares of restricted stock outstanding under the 2006 Plan. Stock Option Awards The Company did not grant any stock options during the three months ended March 31, 2018. Total compensation expense, classified within Payroll and related on the condensed consolidated statements of operations, related to stock options outstanding was $5 for the three months ended March 31, 2017. There was no compensation expense related to stock options outstanding for the three months ended March 31, 2018. Restricted Stock Awards On February 1, 2018, the Company issued 13,115 shares of restricted stock under the 2006 Plan. The fair value per share for such restricted stock awards was $6.10, representing the closing stock price on the date of grant. These shares will vest in three equal installments on each of the first three anniversaries of the date of grant. The total compensation expense, classified within Payroll and related on the condensed consolidated statements of operations, related to restricted stock was $606 and $303 for the three months ended March 31, 2018 and 2017, respectively. The Company adjusted the forfeiture estimates to reflect actual forfeitures. The forfeiture adjustment reduced stock-based compensation expense by $4 and $141 for the three months ended March 31, 2018 and 2017, respectively. As of March 31, 2018, a total of $4,566 in unrecognized compensation expense related to restricted stock awards is expected to be recognized over a weighted-average period of 2.2 years. Stock Grants The Company issued 52,460 shares of common stock to members of the Company’s Board of Directors in respect of their annual retainer on February 1, 2018. The fair value of the shares issued was $6.10 per share and was expensed upon the date of grant. The total compensation expense, classified within general and administrative expenses, related to Board of Directors common stock grants was $320 and $368 for the three months ended March 31, 2018 and 2017, respectively. Management Stock Purchase Plan The Company adopted the 2018 Management Stock Purchase Plan in January 2018, and amended and restated it in March 2018 (the “MSPP”). The purpose of the MSPP is to provide eligible employees of the Company (corporate title of Director or above) an opportunity to voluntarily purchase the Company’s stock in a convenient manner. As of March 31, 2018, shares purchased under this plan did not have a material impact on the Company’s financial statements. The following is a summary of the MSPP, which is qualified in its entirety by the terms of the MSPP. Eligible employees may elect to use up to 20% of their cash compensation (as defined in the MSPP), but in no event more than $200 in any calendar year, to purchase the Company’s common stock generally on a quarterly basis on the open market through a broker (such purchased shares being referred to as “MSPP Shares”). If the participant holds the MSPP Shares for the requisite period specified in the Plan (two years from the purchase date) and remains an employee of the Company, the participant will receive an award of shares of restricted stock under the Company’s 2006 Stock Incentive Plan, as amended, in an amount equal to the number of MSPP Shares that satisfied the holding period. The award will vest on the second anniversary of the award date so long as the participant remains an employee on the vesting date. Awards granted under the Stock Incentive Plan in any calendar year as a result of participants holding the MSPP Shares for the requisite period will be the lesser of (i) 50% of the shares available for grant under the Stock Incentive Plan and (ii) the number of MSPP Shares that have satisfied the two year holding period. Employee Stock Purchase Plan In March 2018, the Board approved, subject to stockholder approval, the Town Sports International Holdings, Inc. Employee Stock Purchase Plan (the “ESPP”), effective as of June 15, 2018. Under the ESPP, an aggregate of 800,000 shares of common stock (subject to certain adjustments to reflect changes in the Company’s capitalization) are reserved and may be purchased by eligible employees who become participants in the ESPP. The purchase price per share of the common stock will be the lesser of 85% of the fair market value of a share of common stock on the offering date or 85% of the fair market value of a share of common stock on the purchase date. This plan has been deemed non-compensatory, and therefore, no compensation expense has been recorded.
