Commitments and Contingencies Disclosure [Abstract]
Other Contingencies	Note 15—Other Contingencies Line of Credit At June 30, 2020, the Company had a $475 million bank line of credit on which to draw for general corporate purposes. Amounts drawn under the line of credit are payable upon demand and generally bear interest at a float rate, based on the Company’s leverage ratio, and starting at LIBOR plus 115 basis points (or if LIBOR becomes unavailable, the higher of the Overnight Bank Funding Rate, plus 50 basis points and the Prime Rate). As of June 30, 2020 there were no borrowings under the line of credit. As of December 31, 2019 there were $10.0 million in borrowings under the line of credit. The line of credit requires the Company to satisfy two financial covenants, with which the Company is in compliance as of June 30, 2020. The line of credit expires on December 21, 2023. At June 30, 2020, the Company also had outstanding $64.9 million in irrevocable standby letters of credit, which relate to payment obligations under the Company’s insurance programs. In connection with the issuance of the letters of credit, the amount available under the line of credit was reduced by $64.9 million to $410.1 million at June 30, 2020. The letters of credit expire on January 2, 2021. Besides the $64.9 million letters of credit there are no other restrictions as to the amount which the Company can draw upon the $475 million line of credit. Tax Jurisdictions and Matters The Company provides services throughout the continental United States and is subject to numerous state and local taxing jurisdictions. In the ordinary course of business, a jurisdiction may contest the Company’s reporting positions with respect to the application of its tax code to the Company’s services, which could result in additional tax liabilities. The Company has tax matters with various taxing authorities. Because of the uncertainties related to both the probable outcomes and amount of probable assessments due, the Company is unable to make a reasonable estimate of a liability. The Company does not expect the resolution of any of these matters, taken individually or in the aggregate, to have a material adverse effect on the consolidated financial position or results of operations based on the Company’s best estimate of the outcomes of such matters. Legal Proceedings The Company is subject to various claims and legal actions in the ordinary course of business. Some of these matters include payroll and employee-related matters and examinations by governmental agencies. As the Company becomes aware of such claims and legal actions, the Company records accruals for any exposures that are probable and estimable. If adverse outcomes of such claims and legal actions are reasonably possible, Management assesses materiality and provides financial disclosure, as appropriate. As previously disclosed, the Securities and Exchange Commission (“SEC”) is conducting an investigation into the Company’s earnings per share (“EPS”) calculation practices. Following receipt of a letter from the SEC in November 2017 regarding its inquiry into those practices followed by a subpoena in March 2018, the Company authorized its outside counsel to conduct an internal investigation, under the direction of the Company’s Audit Committee, into matters related to the SEC subpoena. This investigation was completed in March 2019 and the Company continues to cooperate with the SEC’s investigation and document requests. On March 22, 2019, a putative shareholder class action lawsuit was filed against the Company and its Chief Executive Officer in the U.S. District Court for the Eastern District of Pennsylvania. The initial complaint, which was filed by a plaintiff purportedly on behalf of all purchasers of the Company’s securities between April 11, 2017 and March 4, 2019 (the "Class Period"), alleges violations of the federal securities laws in connection with the matters related to the Company’s EPS calculation practices. On September 17, 2019, the complaint was amended to, among other things, extend the Class Period to cover the period between April 8, 2014 and March 4, 2019, and to name additional individuals affiliated with the Company as defendants. The lead plaintiff seeks unspecified monetary damages and other relief on behalf of the plaintiff class. While the Company is vigorously defending against all litigation claims asserted, this litigation—along with the ongoing SEC investigation—could result in substantial costs to the Company and a diversion of the Company’s management’s attention and resources, which could harm its business. In addition, the uncertainty of the pending lawsuit or potential filing of additional lawsuits could lead to more volatility and a reduction in the Company’s stock price. At this time the Company is unable to reasonably estimate possible losses or form a judgment that an unfavorable outcome is either probable or remote. It is not currently possible to assess whether or not the outcome of these proceedings may have a material adverse effect on the Company. Government Regulations The Company’s customers are concentrated in the healthcare industry and are primarily providers of long-term care many of whom have been significantly impacted by COVID-19. For those customers who were impacted, the pandemic has resulted in increased operating costs, reductions in new resident admitants, and reduced census. The revenues of many of the Company’s customers are highly reliant on Medicare, Medicaid and third party payors’ reimbursement funding rates. New legislation or additional changes in existing regulations could directly impact the governmental reimbursement programs in which the customers participate. There have been several enacted and proposed federal and state relief measures as a result of COVID-19 which should provide support for these customers during this pandemic, however, the full benefit of any such programs would not be realized until these programs are fully implemented, government agencies issue applicable regulations or guidance and such relief is provided.
