COVID-19 Pandemic	Sep. 30, 2020
Unusual or Infrequent Items, or Both [Abstract]
COVID-19 Pandemic	COVID-19 Pandemic The United States broadly continues to experience the COVID-19 pandemic, which has significantly disrupted, and likely will continue to significantly disrupt for some period, the nation’s economy, the senior living industry, and the Company's business. Although a significant portion of the Company's corporate support associates began working from home in March 2020, the Company continues to serve and care for seniors through the pandemic. Due to the average age and prevalence of chronic medical conditions among the Company's residents and patients, they generally are at disproportionately higher risk of hospitalization and adverse outcomes if they contract COVID-19. Upon confirmation of positive COVID-19 exposure at a community, the Company follows government guidance regarding minimizing further exposure, including associates’ adhering to personal protection protocols, restricting new resident admissions, and in some cases isolating residents. Seeking to prevent the introduction of COVID-19 into the Company's communities, and to help control further exposure to infections within communities, in March 2020 the Company began restricting visitors at all of its communities to essential healthcare personnel and certain compassionate care situations, screening associates and permitted visitors, suspending group outings, modifying communal dining and programming to comply with social distancing guidelines and, in most cases, implementing in-room only dining and activities programming, requesting that residents refrain from leaving the community unless medically necessary, and requiring new residents and residents returning from a hospital or nursing home to isolate in their apartment for fourteen days. The Company began easing restrictions on a community-by-community basis in July 2020. Due to the vulnerable nature of the Company's residents, the Company expects restrictions at its communities to continue for some time, and it may revert to more restrictive measures if the pandemic worsens or as necessary to comply with regulatory requirements. The pandemic, including the related restrictions at the Company's communities, have significantly disrupted demand for senior living communities and the sales process, which typically includes in-person prospective resident visits within communities. The pandemic began to adversely impact the Company's occupancy and resident fee revenue during March 2020, as new resident leads, visits (including virtual visits), and move-in activity declined significantly compared to typical levels. Further deterioration of the Company's resident fee revenue will result from lower move-in activity and the resident attrition inherent in its business, which may increase due to the impacts of COVID-19. The Company's home health average daily census also began to decrease in March 2020 due to lower occupancy in its communities and fewer elective medical procedures and hospital discharges. Facility operating expense for the three and nine months ended September 30, 2020 includes $24.5 million and $95.1 million, respectively, of incremental direct costs to prepare for and respond to the pandemic, including costs for: acquisition of additional personal protective equipment ("PPE"), medical equipment, and cleaning and disposable food service supplies, enhanced cleaning and environmental sanitation, increased labor, increased workers compensation and health plan expense, consulting and professional services, and COVID-19 testing of residents and associates where not otherwise covered by government payor or third-party insurance sources. The Company is not able to reasonably predict the total amount of costs it will incur related to the pandemic, and such costs are likely to be substantial. As described further in Note 6, the Company also recorded non-cash impairment charges in its operating results of $8.2 million and $95.2 million for the three and nine months ended September 30, 2020, respectively, for its operating lease right-of-use assets and property, plant and equipment and leasehold intangibles, primarily due to the COVID-19 pandemic and lower than expected operating performance at communities for which assets were impaired. The Company has taken, and continues to take, actions to enhance and preserve its liquidity in response to the pandemic. During the nine months ended September 30, 2020, the Company has completed its financing plans in the regular course of business, including refinancing substantially all of its remaining 2020 and 2021 maturities. In addition, on August 31, 2020, the Company terminated its $250 million revolving credit facility and obtained $266.9 million of non-recourse mortgage financing on 16 communities, most of which had secured the credit facility prior to its termination. See Note 10 for further information regarding the Company's financings. During the nine months ended September 30, 2020, the Company accepted $36.1 million of cash for grants under the Public Health and Social Services Emergency Fund (the "Provider Relief Fund") and $87.5 million of accelerated/advanced Medicare payments, and it deferred $50.1 million of the employer portion of social security payroll taxes. Each of these programs were created or expanded under the Coronavirus Aid, Relief, and Economic Security Act of 2020 ("CARES Act"), as described below. The Company also has delayed or canceled a number of elective capital expenditure projects and suspended repurchases under its existing share repurchase program. On July 26, 2020, the Company restructured its 120 community triple-net master lease with Ventas, Inc. ("Ventas") in a multipart transaction. The components included, among other things, reducing the Company's initial annual minimum rent to $100 million, representing a reduction of approximately $86 million over the twelve months ending June 30, 2021, and removal of the prior requirements that the Company satisfy financial covenants and maintain a security deposit with Ventas. The Company paid a $119.2 million one-time cash lease payment to Ventas in connection with the transaction effective July 26, 2020. See Note 5 for more information about the Ventas Lease Restructuring. As of September 30, 2020, the Company's total liquidity was $490.7 million, consisting of $354.6 million of unrestricted cash and cash equivalents and $136.1 million of marketable securities. The Company continues to seek opportunities to enhance and preserve its liquidity, including through reducing expenses and elective capital expenditures, continuing to evaluate its financing structure and the state of debt markets, and seeking further government-sponsored financial relief related to the COVID-19 pandemic. There is no assurance that debt financing will continue to be available on terms consistent with the Company's expectations or at all, or that the Company's efforts will be successful in seeking further government-sponsored financial relief or regarding the amount of, or conditions required to qualify for, any such relief. In response to the pandemic, on March 27, 2020, the President signed the CARES Act into law, which was amended and expanded by the Paycheck Protection Program and Health Care Enhancement Act signed into law on April 24, 2020. The legislation provides liquidity and financial relief to certain businesses, among other things. The impacts to the Company of certain provisions of the CARES Act are summarized below. •During the three and nine months ended September 30, 2020, the Company accepted $2.6 million and $36.1 million of cash for grants from the Provider Relief Fund, respectively, which was expanded by the CARES Act to provide grants or other funding mechanisms to eligible healthcare providers for healthcare related expenses or lost revenues attributable to COVID-19. The accepted grants were made available pursuant to the following distributions from the Provider Relief Fund: •$28.9 million pursuant to the Phase 1 General Distribution, which generally related to home health, hospice, outpatient therapy, and skilled nursing care provided through the Company's Health Care Services and CCRCs segments. •$4.6 million pursuant to the Skilled Nursing Facility Targeted Distribution, which generally related to the Company's certified skilled nursing facilities. •$2.6 million pursuant to the Nursing Home Infection Control Distribution, which related to its skilled nursing care provided through its CCRCs segments. Further funding may become available to the Company from this distribution based on an incentive program that measures skilled nursing facilities’ COVID-19 infection rates and mortality. The Company has applied for additional grants made available pursuant to the Provider Relief Fund's Phase 2 General Distribution, generally related to its senior housing segments. The amount of such grants are expected to be based on 2% of a portion of the Company's 2018 revenues from patient care. The Company has also applied for additional grants pursuant to the Provider Relief Fund’s Phase 3 General Distribution, for which HHS allocated up to $20 billion. According to HHS’ guidance, eligible applicants will receive grant amounts to ensure that they have received approximately 2% of their annual patient care revenue, plus an additional percentage of their change in revenues minus their operating expenses, in each case from patient care attributable to COVID-19. Grants from the Provider Relief Fund are subject to the terms and conditions of the program, including that such funds may only be used to prevent, prepare for, and respond to COVID-19 and will reimburse only for healthcare related expenses or lost revenues that are attributable to COVID-19. The permissible uses of grants from the Nursing Home Infection Control Distribution are further limited to certain infection control expenses. During the three and nine months ended September 30, 2020, the Company recognized $8.6 million and $35.0 million, respectively, of the grants as other operating income based upon its estimates of its satisfaction of the conditions of the grants during such period. As of September 30, 2020, $1.1 million of unrecognized grants were included in refundable fees and deferred revenue within the Company's condensed consolidated balance sheets. The $36.1 million of grants accepted from the Provider Relief Fund during the nine months ended September 30, 2020 has been presented within net cash provided by (used in) operating activities within the Company's condensed consolidated statement of cash flows. •During the three and nine months ended September 30, 2020, the Company received $2.5 million and $87.5 million, respectively, under the Accelerated and Advance Payment Program administered by CMS, which was temporarily expanded by the CARES Act. Under the program, the Company requested acceleration/advancement of 100% of its Medicare payment amount for a three-month period. The Continuing Appropriations Act, 2021 and Other Extensions Act, enacted on October 1, 2020, amended the repayment terms for accelerated/advanced payments. As amended, recoupment of accelerated/advanced payments will begin one year after payments were issued. Payments will be recouped at a rate of 25% of Medicare payments for the first eleven months following the anniversary of issuance and at a rate of 50% of Medicare payments for the next six months. Any outstanding balance of accelerated/advanced payments will be due following such recoupment period. As of September 30, 2020, $87.5 million is recognized in refundable fees and deferred revenue within the condensed consolidated balance sheets. The $87.5 million received has been presented within net cash provided by operating activities within the Company's condensed consolidated statement of cash flows. •Under the CARES Act, the Company has elected to defer payment of the employer portion of social security payroll taxes incurred from March 27, 2020 to December 31, 2020. One-half of such deferral amount will become due on each of December 31, 2021 and December 31, 2022. As of September 30, 2020, the Company has deferred payment of $50.1 million under the program and presented such amount within other liabilities within the Company's condensed consolidated balance sheets. •The CARES Act temporarily suspended the 2% Medicare sequestration for the period May 1, 2020 to December 31, 2020, which primarily benefits the Company's Health Care Services segment. The Company cannot predict with reasonable certainty the impacts that COVID-19 ultimately will have on its business, results of operations, cash flow, and liquidity, and its response efforts may continue to delay or negatively impact its strategic initiatives, including plans for future growth. The ultimate impacts of COVID-19 will depend on many factors, some of which cannot be foreseen, including the duration, severity, and breadth of the pandemic and any resurgence of the disease; the impact of COVID-19 on the nation’s economy and debt and equity markets and the local economies in its markets; the development and availability of COVID-19 testing, therapeutic agents, and vaccines and the prioritization of such resources among businesses and demographic groups; government financial and regulatory relief efforts that may become available to business and individuals, including its ability to qualify for and satisfy the terms and conditions of financial relief; perceptions regarding the safety of senior living communities during and after the pandemic; changes in demand for senior living communities and the Company's ability to adapt its sales and marketing efforts to meet that demand; the impact of COVID-19 on its residents’ and their families’ ability to afford its resident fees, including due to changes in unemployment rates, consumer confidence, and equity markets caused by COVID-19; changes in the acuity levels of its residents; the disproportionate impact of COVID-19 on seniors generally and those residing in its communities; the duration and costs of its response efforts, including increased equipment, supplies, labor, litigation, testing, and other expenses; the impact of COVID-19 on its ability to complete financings, refinancings, or other transactions (including dispositions) or to generate sufficient cash flow to cover required interest and lease payments and to satisfy financial and other covenants in its debt and lease documents; increased regulatory requirements, including unfunded, mandatory testing; increased enforcement actions resulting from COVID-19, including those that may limit its collection efforts for delinquent accounts; and the frequency and magnitude of legal actions and liability claims that may arise due to COVID-19 or its response efforts.
