Basis of Presentation	Basis of Presentation Town Sports International Holdings, Inc. (the “Company” or “TSI Holdings”) is a diversified holding company that owns subsidiaries engaged in a number of business and investment activities. References to “TSI LLC” refer to Town Sports International, LLC, and references to “TSI Group” refer to Town Sports Group, LLC, both of which are wholly-owned operating subsidiaries of the Company. As of June 30, 2019, the Company owned and operated 190 fitness clubs (“clubs”) under various brand names, primarily located in the United States of America. The Company’s operations are conducted mainly through its clubs and aggregated into one reportable segment. Each of the clubs has similar economic characteristics, services, product offerings and revenues are derived primarily from services to the Company’s members. The Company’s chief operating decision maker is the Chief Executive Officer. The operating segment is the level at which the chief operating decision maker manages the business and reviews operating performance in order to make business decisions and allocate resources. The Company determined that the business is managed and operating performance is reviewed on a consolidated company level and therefore that it has one operating segment.

The results for the three and six months ended June 30, 2019 are not necessarily indicative of the results for the entire year ending December 31, 2019. The Company continues to experience revenue pressure as the fitness industry continues to be highly competitive in the areas in which the Company operates. The Company continues to strategize on improving its financial results and focuses on increasing membership to increase revenue. The Company may consider additional actions within its control, including certain acquisitions, licensing arrangements, the closure of unprofitable clubs upon lease expiration and the sale of certain assets. 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 continue to successfully implement these initiatives could have a material adverse effect on the Company’s liquidity and its operations, and the Company would need to implement alternative plans that could include additional asset sales, additional reductions in operating costs, additional reductions in working capital, debt restructuring and the deferral of capital expenditures. There can be no assurance that such alternatives would be available to the Company or that the Company would be successful in their implementation. The Company’s 2013 Senior Credit Facility is due on November 15, 2020. The Company is currently evaluating its refinancing options. The Company, from time to time, communicates with its existing lenders and/or new potential lenders or investors regarding the availability of debt and/or equity financing to fund working capital and for general corporate purposes, including, without limitation, refinancing the Company’s existing debt and/or to fund acquisitions. Any potential financing will be subject to, among other factors, receipt of satisfactory terms which will depend on market and industry conditions as well as the Company’s operating performance at such time. There can be no assurance that the Company will be able to refinance its debt at market rates and as such may have to seek alternative financing. Certain reclassifications were made to the reported amounts in the consolidated balance sheet as of December 31, 2018 to conform to the presentation as of June 30, 2019. Change in Estimated Average Membership Life The average membership life was 20 months for the six months ended June 30, 2019 and 26 months for the full-year 2018. 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 an annual basis. Joining fees, as well as related direct and incremental expenses of membership acquisition, which may 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 within 45 days of enrollment. Annual fees are amortized over 12 months.
