Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation As of June 30, 2016, Town Sports International Holdings, Inc. (the “Company” or “TSI Holdings”), through its wholly-owned subsidiary, Town Sports International, LLC (“TSI, LLC”), operated 149 fitness clubs (“clubs”) and two BFX Studio (“studio”) locations. The clubs are composed of 102 clubs in the New York metropolitan market under the “New York Sports Clubs” brand name, 27 clubs in the Boston market under the “Boston Sports Clubs” brand name, 12 clubs (one of which is partly-owned) in the Washington, D.C. market under the “Washington Sports Clubs” brand name, five clubs in the Philadelphia market under the “Philadelphia Sports Clubs” brand name and three clubs in Switzerland. We also have one partly-owned club that operated under a different brand name in Washington, D.C. as of June 30, 2016. The Company’s operating segments are New York Sports Clubs, Boston Sports Clubs, Philadelphia Sports Clubs, Washington Sports Clubs and the clubs the Company owned in Switzerland, which is the level at which the chief operating decision makers review discrete financial information and make decisions about segment profitability based on earnings before income tax depreciation and amortization. The Company has determined that these operating segments have similar economic characteristics and meet the criteria which permit them to be aggregated into one reportable segment. Beginning in the first quarter of 2016, the Company's chief operating decision makers do not review studio financial information separately for purposes of making operating decisions and assessing financial performance. Accordingly, the Company manages and reports results through one reportable segment. Previously, the Company managed and reported results through two reportable segments: clubs and studio. Certain reclassifications were made to the reported amounts on the condensed consolidated balance sheet as of December 31, 2015 to conform to the presentation as of June 30, 2016. The condensed consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The condensed consolidated financial statements should be read in conjunction with the Company’s December 31, 2015 consolidated financial statements and notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. The year-end condensed consolidated balance sheet data included within this Form 10-Q was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (“US GAAP”). Certain information and footnote disclosures that are normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted pursuant to SEC rules and regulations. The information reflects all normal and recurring adjustments which, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the interim periods set forth herein. The results for the three and six months ended June 30, 2016 are not necessarily indicative of the results for the entire year ending December 31, 2016. The Company has been experiencing declining revenue from members for several years as the fitness industry continues to be highly competitive in the geographic regions in which the Company competes. New members have been joining at lower monthly rates and cancellations of members paying higher rates will continue to negatively impact the Company's results and liquidity if these trends are not reversed. In response to this, the Company initiated cost savings initiatives in 2015 that continued into fiscal 2016 to help mitigate the impact the decline in revenue has had on its profitability and cash flow from operations. In December 2015, TSI Holdings purchased $29,829 principal amount of debt outstanding under the 2013 Senior Credit Facility in the open market for $10,947, or 36.7% of face value. On April 21, 2016, TSI Holdings settled a transaction to purchase $8,705 principal amount of debt outstanding under the 2013 Senior Credit Facility for $3,787, or 43.5% of face value. On May 6, 2016, TSI Holdings settled another transaction to purchase $62,447 principal amount of debt outstanding under the 2013 Senior Credit Facility for $25,978, or 41.6% of face value. The April and May transactions created gain on extinguishment of debt in the six months ended June 30, 2016 with a tax effect of $13,451. When this was netted with our operating loss, it resulted in a tax provision for the six months ended June 30, 2016 of $12,082. All of the above purchased debt was transferred to Town Sports International, LLC and cancelled. The Company’s ability to fund operations and capital expenditures is dependent upon its ability to generate sufficient cash from operations coupled with cash on hand. The Company believes it has sufficient liquidity from a combination of cash on hand and cash to be generated from operations to fund anticipated capital expenditures and currently scheduled debt service. As further described in Note 3 - Long-Term Debt, the Company maintains a senior credit facility with its lenders which contains a term loan facility and a revolving loan facility. The terms of the senior credit facility include a financial covenant under which the Company is currently not able to utilize more than 25%, or $11,250, of the revolving loan facility. The Company will continue not to be able to utilize more than 25% of the revolving loan facility until it has a total leverage ratio, as defined, of no greater than 4.50:1.00. The revolving loan facility is scheduled to mature in November 2018. The Company continues to focus on increasing membership in existing clubs to increase revenue. The Company may consider additional actions within its control, including the sale of certain assets, additional club closures and entering into arrangements with revenue generating partnerships, some of which will utilize a “shop-in-shop” concept. The Company may also consider additional strategic alternatives including opportunities to reduce TSI LLC's existing debt and further cost savings initiatives, among other possibilities, if any. The Company’s ability to continue to meet its obligations is dependent on its ability to generate positive cash flow from a combination of initiatives, including those mentioned above. Failure to successfully implement these initiatives could have a material adverse effect on our liquidity and our operations and we would need to implement alternative plans that could include additional asset sales, additional reductions in operating costs, deferral of capital expenditures, further reductions in working capital and debt restructurings. There can be no assurance that such alternatives would be available to the Company or that the Company would be successful in their implementation. Change in Estimated Average Membership Life The average membership life was 25 months for the three and six months ended June 30, 2016 and 22 months for the full year of 2015. The Company monitors factors that might affect the estimated average membership life including retention trends, attrition trends, membership sales volumes, membership composition, competition, and general economic conditions, and adjusts the estimate as necessary on a quarterly basis. Joining fees, as well as related direct and incremental expenses of membership acquisition, which include sales commissions, bonuses and related taxes and benefits, are deferred and recognized, on a straight-line basis, in operations over the estimated average membership life or 12 months to the extent these costs are related to the first annual fee paid at the time of enrollment. Annual fees are amortized over 12 months.
