Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies On February 7, 2007, in an action styled White Plains Plaza Realty, LLC v. TSI, LLC et al., the landlord of one of TSI, LLC’s former health and fitness clubs filed a lawsuit in the Appellate Division, Second Department of the Supreme Court of the State of New York against it and two of its health club subsidiaries alleging, among other things, breach of lease in connection with the decision to close the club located in a building owned by the plaintiff and leased to a subsidiary of TSI, LLC, the tenant, and take additional space in a nearby facility leased by another subsidiary of TSI, LLC. Following a determination of an initial award, which TSI, LLC and the tenant have paid in full, the landlord appealed the trial court’s award of damages, and on August 29, 2011, an additional award (amounting to approximately $900) (the “Additional Award”), was entered against the tenant, which has recorded a liability. Separately, TSI, LLC is party to an agreement with a third-party developer, which by its terms provides indemnification for the full amount of any liability of any nature arising out of the lease described above, including attorneys’ fees incurred to enforce the indemnity. As a result, the developer reimbursed TSI, LLC and the tenant the amount of the initial award in installments over time and also agreed to be responsible for the payment of the Additional Award, and the tenant has recorded a receivable related to the indemnification for the Additional Award. The developer and the landlord are currently litigating the payment of the Additional Award and judgment was entered against the developer on June 5, 2013, in the amount of approximately $1,045, plus interest, which judgment was upheld by the appellate court on April 29, 2015. TSI, LLC does not believe it is probable that TSI, LLC will be required to pay for any amount of the Additional Award. In addition to the litigation discussed above, the Company is involved in various other lawsuits, claims and proceedings incidental to the ordinary course of business, including personal injury, construction matters, employee relations claims and landlord tenant disputes. The results of litigation are inherently unpredictable. Any claims against the Company, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time and result in diversion of significant resources. The results of these other lawsuits, claims and proceedings cannot be predicted with certainty. The Company establishes accruals for loss contingencies when it has determined that a loss is probable and that the amount of loss, or range of loss, can be reasonably estimated. Any such accruals are adjusted thereafter as appropriate to reflect changes in circumstances. The Company concluded that an accrual for any such matters is not required as of December 31, 2017.
