Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation and Recent Developments	1. Basis of Presentation and Recent Developments Our financial statements and accompanying notes are prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). In our opinion, the accompanying consolidated financial statements of Tivity Health ® ® By their nature, estimates are subject to an inherent degree of uncertainty. Due We have reclassified certain items in prior periods to conform to current classifications. Following the acquisition of Nutrisystem (the “Merger”), we organize and manage our operations within two reportable segments, based on the types of products and services they offer: Healthcare and Nutrition. The Healthcare segment is comprised our legacy business and includes SilverSneakers ® senior fitness, Prime ® Fitness, WholeHealth Living ® and Wisely Well TM ® and the South Beach Diet ® programs. We have omitted certain financial information that is normally included in financial statements prepared in accordance with U.S. GAAP but that is not required for interim reporting purposes. You should read the accompanying consolidated financial statements in conjunction with the financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2019. Recent Developments On October 18, 2020, we entered into a Stock Purchase Agreement (“Purchase Agreement”) with Kainos NS Holdings LP, a Delaware limited partnership (“Parent”), and KNS Acquisition Corp., a Delaware corporation and indirect wholly owned subsidiary of Parent (“Purchaser,” and collectively with Parent, “Kainos”). Upon the terms and subject to the conditions set forth in the Purchase Agreement, the Company will sell to Kainos all of the issued and outstanding capital stock of Nutrisystem, for a cash purchase price of $575.0 million, subject to customary adjustments. The consummation of the transactions contemplated by the Purchase Agreement, which will result in the disposition of our Nutrition business (the “Nutrition Business”), is expected to occur in the fourth quarter of 2020. The Nutrition Business is comprised of Nutrisystem’s legacy business and includes the Nutrisystem and South Beach Diet programs (see Note 17). COVID-19 In January 2020, the Secretary of the U.S. Department of Health and Human Services (“HHS”) declared a national public health emergency due to a novel strain of coronavirus, which causes the disease known as “COVID-19.” In March 2020, the World Health Organization characterized the outbreak of COVID-19 as a global pandemic, and COVID-19 continues to spread throughout the United States and other countries. Many state and local governments, together with public health officials, have recommended and mandated precautions to mitigate the spread of COVID-19, including ordering closure of certain businesses and imposing stay-at-home orders and social distancing guidelines for individuals. Such measures have resulted in significantly reduced demand for many businesses that have continued in operation. By March 31, 2020, substantially all of the fitness centers in our national network were temporarily closed, which had an adverse impact on the results of operations in our Healthcare segment for the first quarter of 2020 because a significant member visits to a fitness partner location A substantial number of our fitness partner locations remained closed through April, with some locations reopening in May and additional locations reopening in June and throughout the third quarter of 2020. For the month of September 2020 , approximately % of our fitness partner locations reported at least one visit from our SilverSneakers program. For the second and third quarter s of 2020, t he average monthly total participation level s of our SilverSneakers members were significantly below historical levels, and we also experienced a decline in paid subscribers for Prime Fitness, each of which adversely impact ed revenues in our Healthcare segment. We do not believe that COVID-19-related developments had a material impact on the results of operations or cash flows of our Nutrition segment for the first, second, or third quarters of 2020. While overall we did not experience any significant disruptions, interruptions, or increased costs related to our supply chain, inventory, or distribution channels as a result of COVID-19, we experienced delays in fulfilling orders for our Nutrition segment’s products at certain of our warehouses due to some employees of our fulfillment provider testing positive for COVID-19 We have taken a number of actions in response to the pandemic, including the following: • Given the continued uncertainty surrounding COVID-19, in March 2020, we borrowed $75 million under our Revolving Credit Facility as a precautionary measure to increase our cash position and maintain financial flexibility. We repaid such $75 million in full in June 2020. As of September 30, 2020, outstanding debt under our credit agreement was $974.8 million, and we had $56.4 million of cash and cash equivalents. In the third quarter of 2020, we repaid $39.7 million of principal on the term loans under our credit agreement, resulting in our next required quarterly installment being due in March 2022. As of September 30, 2020, we had working capital of $4.8 million. While the COVID-19 pandemic has created significant uncertainty as to general economic and market conditions for the remainder of 2020 and beyond, as of the date of this report, we believe our cash on hand, expected cash flows from operations, net proceeds from the expected sale of our Nutrition segment, and anticipated available credit under the Credit Agreement (as defined below) will be sufficient to fund our operations, principal and interest payments, and capital expenditures for the next 12 months • We have taken a variety of measures to ensure the availability and functioning of our critical infrastructure, to promote the safety and security of our employees and to support the communities in which we operate. These measures include implementing remote working arrangements for employees where practicable. We are following public and private sector policies and initiatives to reduce the transmission of COVID-19, such as the imposition of travel restrictions, the promotion of social distancing, and the adoption of work-from-home arrangements. • We are focused on preserving our liquidity and managing our cash flow, including, but not limited to, managing our working capital, optimizing tax savings under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) and other COVID-19-related legislation, curtailing capital expenditures, reducing discretionary spending, and reducing compensation costs. o In April 2020, we furloughed 13% of our approximately 1,000 employees. In June 2020, some of these furloughed employees’ positions were eliminated (in addition to other position eliminations, resulting in approximately 8% of our employees being terminated), and we extended the furlough for substantially all of the remaining furloughed employees through the end of 2020. Also in June 2020, we placed an additional 2% of our total employees on furlough through the end of 2020. o Also in April 2020, the Compensation Committee of the Company’s Board of Directors (the “Board”) approved a 25% reduction in base salary for the Company’s executive officers and certain other employees for the period from April 20, 2020 through August 23, 2020. In June 2020, the Compensation Committee determined to extend such reductions in base salary through December 31, 2020 . Additionally, the Board approved a 100% reduction in the annual cash retainer and annual committee retainers payable to non-management members of the Board who stood for reelection at the 2020 Annual Meeting of Stockholders (except for Daniel G. Tully who did not receive compensation for his service on the Board) for a period of four months , beginning May 1, 2020. In June 2020, the Board determined to extend such reduction in cash compensation to the Board through December 31, 2020. o Effective at the end of July 2020, the Compensation Committee suspended the Company matching contribution to the Company’s 401(k) plan. As a result of the COVID-19 pandemic, in March 2020, we experienced a significant decline in the Company’s market capitalization and in the actual and forecasted operating results of our Healthcare segment, in addition to the unfavorable change in market conditions which consist of the Nutrisystem tradename and the SilverSneakers tradename) including $80.0 million related to the Nutrisystem tradename and $119.5 million related to goodwill allocated to the Nutrition segment. There were no impairment triggers during the second quarter of 2020 related to our goodwill or indefinite-lived intangible assets. During the third quarter of 2020, we recorded an additional impairment loss of $66.2 million related to goodwill allocated to the Nutrition segment (see Note 12).

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Relevant Accounting Standards	2 . Re c o a d In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04, “ Reference Rate Reform (“ASC 848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting”. ASC 848 contains temporary optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform, such as a transition away from the use of LIBOR. ASC 848 was effective for the Company as of January 1, 2020. The provisions of ASC 848 are available through December 31, 2022, at which time the reference rate replacement activity is expected to have been completed. The provisions of ASC 848 must be applied at a Topic, Subtopic or Industry Subtopic level for all transactions other than derivatives, which may be applied at a hedging relationship level. The accounting relief provided by ASC 848 is applicable only to legacy contracts if the amendments made to the agreements are solely for reference rate reform activities. Modifications that are unrelated to reference rate reform will scope out a given contract. ASC 848 allows for different elections to be made at different points in time, and the timing of those elections will be documented as applicable. For the avoidance of doubt, we intend to reassess the elections of optional expedients and exceptions included within ASC 848 related to our hedging activities and will document the election of these items on a quarterly basis. In March 2020, we elected the expedient that allows us to assume that our hedged interest payments are probable of occurring regardless of any expected modification in their terms related to reference rate reform. In addition, we have the option to change the method of assessing effectiveness upon a change in the critical terms of the derivative or the hedged transactions and upon the end of relief under ASC 848. In June 2020, we elected to (i) continue the method of assessing effectiveness as documented in the original hedge documentation and (ii) apply the expedient wherein the reference rate on the hypothetical derivative matches the reference rate on the hedging instrument. We will also apply the aforementioned elections to any future designated cash flow hedging relationship. In October 2018, the FASB issued ASU 2018-16, "Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (“SOFR”) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes" (“ASU 2018-16”), which adds the OIS rate based on SOFR as a U.S. benchmark interest rate to facilitate the LIBOR to SOFR transition and provide lead time for entities to prepare for changes to interest rate risk hedging strategies. ASU 2018-16 is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. As of September 30, 2020, the benchmark interest rate in our existing interest rate swap agreements is LIBOR. The adoption of this standard did not have an impact on our financial position, results of operations, or cash flows . In January 2017, the FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other” (“ASU 2017-04”), which simplifies the subsequent measurement of goodwill by eliminating step two from the goodwill impairment test. ASU 2017-04 is effective for annual and interim impairment tests in fiscal years beginning after December 15, 2019 and is required to be applied prospectively. Early adoption is allowed for annual goodwill impairment tests performed on testing dates after January 1, 2017. We adopted ASU 2017-04 on October 1, 2019. As further discussed in Note 12, we recorded impairment losses related to goodwill during the fourth quarter of 2019 and the first and third quarter s of 2020 . In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”), which changes the fair value measurement disclosure requirements of ASC 820. ASU 2018-13 is effective for fiscal years beginning on or after December 15, 2019, including interim periods therein, and is generally required to be applied retrospectively, except for certain components that are to be applied prospectively. The adoption of this standard did not have a material impact on our consolidated financial statements and related disclosures In August 2018, the FASB issued ASU No. 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” which requires implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement. This standard is effective for annual periods beginning after December 15, 2019, and interim periods within those fiscal years. The adoption of this standard did not have a material impact on our consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”), which requires companies to measure credit losses for financial assets held at the reporting date utilizing a methodology that reflects current expected credit losses over the lifetime of such assets. ASU 2016-13 was effective for the Company on January 1, 2020 and is generally required to be applied using the modified retrospective approach, with limited exceptions for specific instruments. The adoption of this standard did not have a material impact on our consolidated financial statements and related disclosures.

Revenue From Contract With Customer [Abstract]
Revenue Recognition	3 . Revenue Recognition We account for revenue from contracts with customers in accordance with Accounting Standards Codification (“ASC”) Topic 606. The unit of account in ASC Topic 606 is a performance obligation, which is a promise in a contract to transfer to a customer either a distinct good or service (or bundle of goods or services) or a series of distinct goods or services provided over a period of time. ASC Topic 606 requires that a contract's transaction price, which is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer, is to be allocated to each performance obligation in the contract based on relative standalone selling prices and recognized as revenue when or as the performance obligation is satisfied. Healthcare Segment Our Healthcare segment earns revenue primarily from three programs, SilverSneakers senior fitness, Prime Fitness and WholeHealth Living. We provide the SilverSneakers senior fitness program to members of Medicare Advantage, Medicare Supplement, and group retiree plans through our contracts with such plans. We offer Prime Fitness, a fitness facility access program, through contracts with commercial health plans, employers, and other sponsoring organizations that allow their members to individually purchase the program. We sell our WholeHealth Living program primarily to health plans. Except for Prime Fitness, our Healthcare segment’s customer contracts generally have initial terms of approximately three years. Some contracts allow the customer to terminate early and/or determine on an annual basis to which of their members they will offer our programs. For Prime Fitness, our contracts with commercial health plans, employers, and other sponsoring organizations generally have initial terms of approximately three years, while i . The significant majority of Healthcare segment’s customer contracts contain one performance obligation - to stand ready to provide access to our network of fitness locations and fitness programming - which is satisfied over time as services are rendered each month over the contract term. There are generally no performance obligations that are unsatisfied at the end of a particular month. There was no material revenue recognized during the three and nine months ended September 30, 2020 from performance obligations satisfied in a prior period. Our fees within the the average monthly total participation levels of our members were significantly lower than in the third quarter of 2019 due to the COVID-19 pandemic. As a result, revenues from PMPM fees represented 59% of SilverSneakers revenue for the third quarter of 2020, compared to 33% for the third quarter of 2019. Our Healthcare segment’s customer contracts include variable consideration, which is allocated to each distinct month over the contract term based on eligible members and/or member visits each month. The allocated consideration corresponds directly with the value to our customers of our services completed for the month. Under the majority of Healthcare segment’s contracts, we recognize revenue each month using the practical expedient available under ASC 606-10-55-18, which provides that revenue is recognized in the amount for which we have the right to invoice. Although we evaluate our financial performance and make resource allocation decisions based upon the results of our two reportable segments, we believe the following information depicts how our Healthcare segment revenues and cash flows are affected by economic factors. The following table sets forth Healthcare revenue disaggregated by program. Revenue from our SilverSneakers program is predominantly contracted with Medicare Advantage and Medicare Supplement plans. (In thousands) Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 SilverSneakers $ 68,613 $ 124,602 $ 239,377 $ 370,524 Prime Fitness 21,687 30,499 73,545 88,993 WholeHealth Living 5,040 4,752 14,835 13,783 Other (1) 141 126 9,339 687 $ 95,481 $ 159,979 $ 337,096 $ 473,987 (1) For the nine months ended September 30, 2020, other revenue in the table above includes $6.8 million from a well-being program with a large employer. For the three and nine months ended September 30, 2020, other revenue in the table above also includes $0.1 million and $2.2 million, respectively, of Wisely Well revenue. Sales and usage-based taxes are excluded from revenues. Nutrition Segment Our Nutrition segment earns revenue from four sources: direct to consumer, retail, QVC and other. Revenue is measured based on the consideration specified in a contract with a customer and excludes any sales incentives and amounts collected on behalf of third parties. As explained in more detail below, revenue is recognized upon satisfaction of the performance obligation by transferring control over a product to a Nutrition segment customer. Direct-mail advertising costs are expensed as incurred. We recognize an asset for the carrying amount of product to be returned and for costs to obtain a contract if the amortization is more than one year in duration. We expense costs to obtain a contract as incurred if the amortization period is less than one year. We sell pre-packaged foods directly to weight loss program participants primarily through the Internet and telephone (referred to as the direct to consumer channel), through QVC (a television shopping network), and select retailers. Pre-packaged foods include both frozen and non-frozen (ready-to-go), shelf-stable products. Products sold through the direct to consumer channel, both frozen and non-frozen, may be sold separately (a la carte) or as part of a packaged monthly meal plan for which customers pay at the point of sale. Products sold through QVC are payable by QVC upon our shipment of the product to the end consumer. For both the direct to consumer channel and QVC, we recognize revenue at a point in time, i.e., at the shipping point. Direct to consumer customers may return unopened ready-to-go Nutrisystem products within 30 days after purchase in order to receive a refund or credit. Frozen Nutrisystem products are refundable only if the order is canceled within 14 days after delivery. South Beach Diet products are not refundable. Products sold to retailers include both frozen and non-frozen products and are payable by the retailer upon receipt. We recognize revenue at a point in time, i.e., when the retailers take possession of the product. Certain retailers have the right to return unsold products. We account for the shipment of frozen and non-frozen, ready-to-go products as separate performance obligations. The consideration, including variable consideration for product returns, is allocated between frozen and non-frozen products based on their standalone selling prices. The amount of revenue recognized is adjusted for expected returns, which are estimated based on historical data. In addition to our pre-packaged foods, we sell prepaid gift cards through a wholesaler that are redeemable through the Internet or telephone. Prepaid gift cards represent grants of rights to goods to be provided in the future to gift card buyers. The wholesaler has the right to return all unsold prepaid gift cards. The wholesaler’s retail selling price of the gift cards is deferred in the balance sheet and recognized as revenue when we have satisfied our performance obligation, i.e., when a gift card holder redeems the gift card with us. We recognize breakage amounts (the estimated amount of unused gift cards) as revenue, in proportion to the actual gift card redemptions exercised by gift card holders in relation to the total expected redemptions of gift cards. We utilize historical experience in estimating the total expected breakage and period over which the gift cards will be redeemed. Sales and other taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the Company from a Nutrition segment customer are excluded from revenue and presented on a net basis. After control over a product has transferred to a Nutrition segment customer, shipping and handling costs associated with outbound freight are accounted for as a fulfillment cost and are included in revenue and cost of revenue in the accompanying consolidated statements of operations. Revenue from shipping and handling charges was $5.8 million and $18.7 million for the three and nine months ended September 30, 2020, respectively, and $5.3 million and $13.4 million for the three and six months ended September 30, 2019 (from March 8, 2019 forward), respectively.

The contract liabilities (deferred revenue) primarily relate to sale of prepaid gift cards and unshipped foods, which are deferred until such time as the Company has satisfied its performance obligations. Significant changes in the contract liabilities (deferred revenue) balance during the period are as follows: Three Months Ended September 30, Nine Months Ended September 30, (In thousands) 2020 2020 Revenue recognized that was included in the contract liability (deferred revenue) balance on January 1, 2020 $ (931 ) $ (7,692 ) Increases due to cash received for prepaid gift cards sold or unshipped food, excluding amounts recognized as revenue, reduced by (decreases) due to returns $ 3,202 $ 9,989 The following table includes estimated revenue from the prepaid gift cards expected to be recognized in the future related to performance obligations that are unsatisfied (or partially satisfied) at the end of the reporting period: (In thousands) Remaining 2020 $ 1,303 2021 3,097 2022 1,649 2023 993 2024 692 2025 286 $ 8,020 We apply the practical expedient in subtopic ASC 606-10-50-14 and do not disclose information about remaining performance obligations that have original expected durations of one year or less. We review the reserves for our customer returns at each reporting period and adjust them to reflect data available at that time. To estimate reserves for returns, we consider actual return rates in preceding periods and changes in product offerings or marketing methods that might impact returns going forward. To the extent the estimate of returns changes, we will adjust the reserve, which will impact the amount of revenue recognized in the period of the adjustment. The provision for estimated returns for the three and nine months ended September 30, 2020 was $3.7 million and $13.0 million, respectively, and for the three and nine months ended September 30, 2019 ( he reserve for estimated returns incurred but not received and processed was In October 2020, we entered into the Purchase Agreement that will result in the disposition of our Nutrition segment, which is expected to occur in the fourth quarter of 2020 (see Note 17).

Inventories	4 . Inventories Inventories consist principally of packaged food held in external fulfillment locations. We value inventories at the of cost or net realizable value, with cost determined using the first-in, first-out method. We continually assess quantities of inventory on hand to identify excess or obsolete inventory and record a provision for any estimated loss. We estimate the reserve for excess and obsolete inventory primarily on forecasted demand and/or our ability to sell the products, introduction of new products and packaging, future production requirements, and changes in consumer behavior. The reserve for excess and obsolete inventory was $2.2 million and $1.8 million at September 30, 2020 and December 31, 2019, respectively.

Intangible Assets and Goodwill	5 . Intangible Assets and Goodwill The COVID-19 pandemic has had and is having an adverse impact on the overall economy, resulting in rapidly changing market and economic conditions that have impacted the Company. In March 2020, we experienced a significant decline in the Company’s market capitalization and in the actual and forecasted operating results of our Healthcare segment, in addition to the unfavorable change in market conditions. As a result, management concluded that there were triggering events during the first quarter of 2020 necessitating an impairment evaluation of our goodwill and indefinite-lived intangible assets . Through this evaluation, management concluded that the fair value of goodwill allocated to the Nutrition business unit as well as the fair value of the Nutrisystem tradename were below their carrying amounts, and i 119.5 Nutrisystem . On October 18, 2020, we accepted an offer to sell the Nutrition business unit for $575.0 million, which indicated that the fair value for the Nutrition business unit was below its carrying value as of September 30, 2020. We performed an impairment assessment in accordance with the held and used model and determined that the fair values of all assets and liabilities allocated to the Nutrition segment exceeded their carrying amounts recorded an impairment loss of $66.2 None A reconciliation of our goodwill balance is as follows: (In thousands) Healthcare Nutrition Consolidated Balance, January 1, 2020 $ 334,680 $ 319,955 $ 654,635 Impairment loss — (185,698 ) $ (185,698 ) Balance, September 30, 2020 $ 334,680 $ 134,257 $ 468,937 At September 30, 2020 and December 31, 2019, intangible assets not subject to amortization consist of tradenames of $509.0 million and $ 589.0

Incom Taxes For the three months ended September 30, 2020, we had income tax expense of $2.2 million on a pre-tax loss of $40.2 million, primarily due to the nondeductible goodwill impairment loss of $66.2 million recorded during the third quarter of 2020. For the nine months ended September 30, 2020 and 2019, we had an effective tax benefit rate of 3.1% and an effective income tax rate of 33.4%, respectively. For the nine months ended September 30, 2020, our effective tax benefit rate was lower than our statutory benefit rate primarily due to the nondeductible goodwill impairment losses of $119.5 million and $66.2 million recorded during the first and third quarters, respectively. For the nine months ended September 30, 2019, our effective income tax rate was higher than our statutory tax rate due to nondeductible expenses related to the acquisition of Nutrisystem as well as two adjustments related to the acquisition that collectively increased our income tax expense for such period by approximately $2.7 million: (i) We file income tax returns in the U.S. Federal jurisdiction and in various state and foreign

Leases [Abstract]
Leases	9 . Leases We maintain lease agreements principally for our office spaces and certain equipment. In addition, certain of our contracts, such as those with our fulfillment vendor related to our warehouse space or contracts with certain equipment vendors, contain embedded leases. We maintain two sublease agreements with respect to one of our office locations, each of which continues through the initial term of our master lease agreement. Such sublease income and payments, while they reduce our rent expense, are not considered in the value of the right-of-use asset or lease liability. With the exception of two finance leases related to a network server and office equipment, all of our leases are classified as operating leases In the second quarter of 2020, we negotiated rent deferrals for our Nutrition segment’s corporate office in Fort Washington, Pennsylvania. The amended contract provides a total deferral of $0.4 million on a portion of the June, July, and August 2020 lease payments, with no substantive changes to the original contract. We have been repaying this deferral in 12 equal monthly installments beginning in September 2020. Consistent with updated guidance from the FASB in April 2020, we have elected to treat the COVID-19 pandemic-related rent deferrals as accrued liabilities. During the deferral periods we will continue to recognize expense as if no deferral had been provided. The following table shows the components of lease expense for the three and nine months ended September 30, 2020 and 2019: Three Months Ended September 30, Nine Months Ended September 30, (In thousands) 2020 2019 2020 2019 Finance lease cost: Amortization of leased assets $ 162 $ 12 $ 485 $ 36 Interest of lease liabilities 19 2 67 5 Operating lease cost 3,675 3,924 11,025 10,444 Short-term lease cost 154 134 420 283 Total lease cost before subleases $ 4,010 $ 4,072 $ 11,997 $ 10,768 Sublease income (1,344 ) (1,378 ) (4,108 ) (4,078 ) Total lease cost, net $ 2,666 $ 2,694 $ 7,889 $ 6,690 Supplemental cash flow information related to leases is as follows: Three Months Ended September 30, Nine Months Ended September 30, (In thousands) 2020 2019 2020 2019 Cash paid for amounts included in the measurement of lease liabilities Operating cash flow attributable to operating leases $ (2,912 ) $ (1,701 ) $ (8,524 ) $ (6,809 ) Operating cash flow attributable to finance leases (19 ) (2 ) (67 ) (5 ) Financing cash flow attributable to finance leases (158 ) (11 ) (464 ) (34 ) Supplemental noncash information: Right-of-use assets obtained in exchange for operating lease liabilities (1) — 4,711 — 53,683 Right-of-use assets obtained in exchange for finance lease liabilities (1) — — — 181 (1) No new leases were entered into during the nine months ended September

The Credit Agreement provides us with (i) a $350.0 million term loan A facility (“Term Loan A”), (ii) an $830.0 million term loan B facility (“Term Loan B” and, together with Term Loan A, the “Term Loans”), (iii) a $125.0 million revolving credit facility that includes a $35.0 million sublimit for swingline loans and a $50.0 million sublimit for letters of credit (the “Revolving Credit Facility”; Term Loan A, Term Loan B and the Revolving Credit Facility are sometimes herein referred to collectively as the “Credit Facilities”), and (iv) uncommitted incremental accordion facilities in an aggregate amount at any date equal to the greater of $125.0 million or 50% of our consolidated EBITDA for the then-preceding four fiscal quarters, plus additional amounts based on, among other things, satisfaction of certain financial ratio requirements. As of September 30, 2020, outstanding debt under the Credit Agreement was $974.8 million, and availability under the Revolving Credit Facility totaled $124.5 million as calculated under the most restrictive covenant. We are required to repay Term Loan A loans in consecutive quarterly installments, each in the amount of 2.50% of the aggregate initial amount of such loans, payable beginning on June 30, 2019 and on the last day of each succeeding quarter thereafter until maturity on March 8, 2024, at which time the entire outstanding principal balance of such loans is due and payable in full. We are required to repay Term Loan B loans in consecutive quarterly installments, each in the amount of 0.75% of the aggregate initial amount of such loans, payable beginning on June 30, 2019 and on the last day of each succeeding quarter thereafter until maturity on March 8, 2026, at which time the entire outstanding principal balance of such loans is due and payable in full. We are permitted to make voluntary prepayments of borrowings under the Term Loans at any time without penalty. From March 8, 2019 through September 30 , 2020 The Credit Agreement contains a financial covenant that requires us to maintain maximum ratios or levels of consolidated total net debt to consolidated adjusted EBITDA, calculated as provided in the Credit Agreement (the “Net Leverage Ratio”), of 5.75:1.00 for all test dates occurring on or after December 31, 2019 but prior to December 31, 2020, 5.25:1.00 for all test dates occurring on or after December 31, 2020 but prior to December 31, 2021, and 4.75:1.00 for all test dates occurring on or after December 31, 2021. As of September 30, 2020, we were in compliance with all of the covenant requirements of the Credit Agreement, and our Net Leverage Ratio was equal to 3.81. Based on our current assumptions with respect to the COVID-19 pandemic, including, among other things, the divestiture of the Nutrition Business and the resulting paydown of principal on the term loans under our Credit Agreement, our fitness partner locations reopening and/or remaining open , and the average monthly total participation levels of our members at such locations, we currently believe we will be in compliance with the Net Leverage Ratio covenant over the next 12 months. We will continue to monitor our projected ability to comply with all covenants under the Credit Agreement, including the Net Leverage Ratio . Borrowings under the Credit Agreement bear interest at variable rates based on a margin or spread in excess of either (1) one-month, two-month, three-month or six-month LIBOR (or, with the approval of all lenders holding the particular class of loans, 12-month LIBOR), which may not be less than zero, or (2) the greatest of (a) the prime lending rate of the agent bank for the particular facility, (b) the federal funds rate plus 0.50%, and (c) one-month LIBOR plus 1.00% (the “Base Rate”), as selected by the Company. The LIBOR margin for Term Loan A loans is 4.25%, the LIBOR margin for Term Loan B loans is 5.25% and the LIBOR margin for revolving loans varies between 3.75% and 4.25%, depending on our total Net Leverage Ratio. The Base Rate margin for Term Loan A loans is 3.25%, the Base Rate margin for Term Loan B loans is 4.25% and the Base Rate margin for revolving loans varies between 2.75% and 3.25%, depending on our total Net Leverage Ratio. In May 2019, we entered into eight amortizing interest rate swap agreements, each of which matures in May 2024. Under these agreements, we receive a variable rate of interest based on LIBOR, and we pay a fixed rate of interest equal to approximately 2.2% plus a spread, as described in the preceding sentences. As of September 30, 2020, these interest rate swap agreements had current notional amounts totaling $800.0 million. The Credit Agreement also provides for annual commitment fees ranging between 0.250% and 0.500% of the unused commitments under the Revolving Credit Facility, depending on our total Net Leverage Ratio, and annual letter of credit fees on the daily outstanding availability under outstanding letters of credit at the applicable LIBOR margin for the Revolving Credit Facility, depending on our total Net Leverage Ratio. Extensions of credit under the Credit Agreement are secured by guarantees from substantially all of the Company’s active material domestic subsidiaries and by security interests in substantially all of Company’s and such subsidiaries’ assets. The Credit Agreement contains a financial covenant that requires us to maintain specified maximum ratios or levels of consolidated total net debt to EBITDA, calculated as provided in the Credit Agreement. The Credit Agreement also contains various other affirmative and negative covenants customary for financings of this type that, subject to certain exceptions, impose restrictions and limitations on the Company and certain of the Company’s subsidiaries with respect to, among other things, indebtedness; liens; negative pledges; restricted payments (including dividends, distributions, buybacks, redemptions, repurchases with respect to equity interests, and payments, redemptions, retirements, purchases, acquisitions, defeasance, exchange, conversion, cancellation or termination with respect to junior lien, subordinated or unsecured debt); restrictions on subsidiary distributions; loans, advances, guarantees, acquisitions and other investments; mergers and other fundamental changes; sales and other dispositions of assets (including equity interests in subsidiaries); sale/leaseback transactions; transactions with affiliates; conduct of business; amendments and waivers of organizational documents and material junior debt agreements; and changes to fiscal year.

Commitments and Contingencies	1 1 . Commitment an Contingencies Shareholder Lawsuits: Weiner Lawsuit and Consolidated Derivative Lawsuit On November 6, 2017, United Healthcare issued a press release announcing expansion of its fitness benefits (“United Press Release”), and the market price of the Company's shares of common stock, par value $.001 per share (“Common Stock”) dropped on that same day. In connection with the United Press Release, four lawsuits were filed against the Company. On November 20, 2017, Eric Weiner, claiming to be a stockholder of the Company, filed a complaint on behalf of stockholders who purchased Common Stock between February 24, 2017 and November 3, 2017 (“Weiner Lawsuit”). The Weiner Lawsuit was filed as a class action in the U.S. District Court for the Middle District of Tennessee, naming as defendants the Company, the Company's chief executive officer, chief financial officer and a former executive who served as both chief accounting officer and interim chief financial officer. The complaint alleges that the defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Rule 10b-5 promulgated under the Exchange Act in making false and misleading statements and omissions related to the United Press Release. The complaint seeks monetary damages on behalf of the purported class. On April 3, 2018, the Court entered an order appointing the Oklahoma Firefighters Pension and Retirement System as lead plaintiff and designated counsel for the lead plaintiff. . We are currently unable to predict the probable outcome of the Weiner Lawsuit or to reasonably estimate a range of potential loss, if any. We intend to vigorously defend ourselves against the Weiner Lawsuit. On January 26, 2018 and August 24, 2018, individuals claiming to be stockholders of the Company filed shareholder derivative actions, on behalf of the Company, in the U.S. District Court for the Middle District of Tennessee, naming the Company as a nominal defendant and certain current and former executives and directors as defendants. On October 15, 2018, the two complaints were consolidated (the “Consolidated Derivative Lawsuit”). On May 15, 2019, a consolidated amended complaint was filed. The consolidated amended complaint asserts claims for violation of Section 10(b), 14(a), and 29(b) of the Exchange Act, breach of fiduciary duty, waste of corporate assets, and unjust enrichment. Plaintiffs seek to recover damages on behalf of the Company, certain corporate governance and internal procedural reforms, and other equitable relief. On May 19, 2020, after the parties entered into a Memorandum of Understanding (“MOU”) to resolve the Consolidated Derivative Lawsuit, the case was remanded to the District Court to review and effectuate the proposed MOU settlement. On October 9, 2020, the parties filed a Stipulation of Settlement (the “Settlement”) with the District Court. The principal terms of the Settlement provide for certain corporate governance changes in exchange for a release of claims. On October 27, 2020, the District Court entered an order preliminarily approving the Settlement. The final settlement approval hearing is set for February 19, 2021 . Shareholder Lawsuits: Strougo, Cobb, and Delaware Lawsuits On February 25, 2020, Robert Strougo, claiming to be a stockholder of the Company, filed a complaint on behalf of stockholders who purchased C ommon S tock between March 8, 2019 and February 19, 2020 (the "Strougo Lawsuit"). The Strougo Lawsuit was filed as a putative class action in the U.S. District Court for the Middle District of Tennessee, naming the Company, the Company's chief financial officer and former chief executive officer as defendants. The complaint alleges that the defendants violated Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated under the Exchange Act in making false and misleading statements and omissions related to the performance of the Nutrisystem business that the Company acquired on March 8, 2019 . The complaint seeks monetary damages on behalf of the purported class. On August 18, 2020, the Court appointed Sheet Metal Workers Local No. 33, Cleveland District, Pension Fund as lead pl aintiff. The deadline for lead plaintiff to file its amended complaint is November 13, 2020. On April 9, 2020, John Cobb, claiming to be a stockholder of the Company, filed a derivative complaint in the United States District Court for the Middle District of Tennessee naming the Company as a nominal defendant and certain directors and the Company’s former chief executive officer and current chief financial officer as defendants (the “Cobb Lawsuit”). The complaint asserted claims for breach of Section 14(a) of the Exchange Act, breach of fiduciary duty, waste of corporate assets, failure of internal controls, and unjust enrichment, largely tracking the factual allegations in the Strougo Lawsuit. The plaintiff seeks monetary damages on behalf of the Company, restitution, and certain corporate governance and internal procedural reforms. On June 9, 2020, the United States Magistrate Judge approved the parties’ stipulation to stay the case pending the resolution of defendants’ anticipated motion to dismiss in the Strougo case. In July 2020, three putative derivative complaints were filed in the United States District Court for the District of Delaware by the following individuals claiming to be stockholders of the Company: Patrick Yerby, Thomas R. Conte, Melvyn Klein, and Mark Ridendour (the “Delaware Derivative Lawsuits”). The complaints largely track the allegations, named defendants, asserted claims, and requested relief of the Cobb Lawsuit. The three Delaware Derivative Lawsuits have been consolidated and stayed on terms similar to that entered in the Cobb Lawsuit. Given the uncertainty of litigation and the preliminary stage of the Strougo Lawsuit, Cobb Lawsuit and Delaware Derivative Lawsuits, we are currently unable to predict the probable outcome of the matters or to reasonably estimate a range of potential loss, if any. We intend to vigorously defend ourselves against these lawsuits. Trademark Lawsuit: Pacific Packaging Lawsuit On May 31, 2019, Pacific Packaging Concepts, Inc. (“Pacific Packaging”) filed a complaint in the U.S. District Court for the Central District of California, Western Division, naming as defendants two subsidiaries of the Company; Nutrisystem, Inc. and Nutri/System IPHC, Inc. In its complaint, Pacific Packaging alleged that the defendants’ use of Pacific Packaging’s federally registered trademark, Fresh Start, in advertisements for its weight management program and shakes constitutes federal trademark infringement, counterfeit trademark infringement, false designation of origin, federal trademark dilution, unfair competition, false advertising, common law unfair competition, and common law trademark infringement. The complaint seeks injunctive relief and monetary damages in an unspecified amount. On August 29, 2019, the defendants filed their Answer to Complaint. Given the uncertainty of litigation and the preliminary stage of the case, we are currently not able to predict the probable outcome of the matter or to reasonably estimate a range of potential loss, if any. We intend to vigorously defend ourselves against this complaint. Other Additionally, from time to time, we are subject to contractual disputes, claims and legal proceedings that arise in the ordinary course of our business. Some of the legal proceedings pending against us as of the date of this report are expected to be covered by insurance policies. As these matters are subject to inherent uncertainties, our view of these matters may change in the future. We expense legal costs as incurred

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	1 2 . Fai Valu Measu r ments We account for certain assets and liabilities at fair value. Fair value is defined as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date, assuming the transaction occurs in the principal or most advantageous market for that asset or liability. Fair Value Hierarchy The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are: Level 1: Quoted prices in active markets for identical assets or liabilities; Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-based valuation techniques in which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3: Unobservable inputs that are supported by little or no market activity and typically reflect management's estimates of assumptions that market participants would use in pricing the asset or liability. Asse t i e i e n i T he following table presents our assets and liabilities measured at fair value on a recurring basis at September 30, 2020 and December 31, 2019. Level 2 (In thousands) September 30, 2020 December 31, 2019 Liabilities: Interest rate swap agreements $ 40,583 $ 16,238 The fair values of interest rate swap agreements are primarily determined based on the present value of future cash flows using internal models and third-party pricing services with observable inputs, including interest rates, yield curves and applicable credit spreads. Asse t i e i Non- e n i We measure certain assets at fair value on a nonrecurring basis in the fourth quarter of each year, including the following: • reporting units measured at fair value as part of a goodwill impairment test; and • indefinite-lived intangible assets measured at fair value for impairment assessment. Each of these assets above is classified as Level 3 within the fair value hierarchy. The COVID-19 pandemic has had and is having an adverse impact on the overall economy, resulting in rapidly changing market and economic conditions that have impacted the Company. In March 2020, we experienced a significant decline in the Company’s market capitalization and in the actual and forecasted operating results of our Healthcare segment, in addition to the unfavorable change in market conditions. As a result, management concluded that there were triggering events during the first quarter of 2020 necessitating an impairment evaluation of our goodwill (for each of our reporting units) and indefinite-lived intangible assets (which consist of the Nutrisystem tradename and the SilverSneakers tradename). We estimated the fair value of each reporting unit using a combination of a discounted cash flow model and a market-based approach, and we reconciled the aggregate fair value of our reporting units to our consolidated market capitalization. Estimating fair value requires significant judgments, including management’s estimate of future cash flows of each reporting unit (which is dependent on internal forecasts of projected income), estimation of the long-term growth rates of future revenues for our reporting units, the terminal growth rate of revenue, the tax rate, and determination of the weighted average cost of capital, as well as relevant comparable company revenue and earnings multiples and market participant acquisition premium for the market-based approaches. Changes in these estimates and assumptions could materially affect the estimate of fair value and goodwill impairment for each reporting unit. There is significant uncertainty relating to the potential future impacts of the COVID-19 pandemic on our business and the overall market. Certain significant inputs used in the estimation of fair value were adversely impacted by the changing market and economic conditions discussed above, most notably the weighted average cost of capital, resulting in a lower estimated fair value for each of our reporting units. Before we performed the impairment analysis during the first quarter, the estimated fair value of the Nutrition reporting unit was equal to its carrying value due to an impairment loss we recorded in the fourth quarter of 2019. Because there was no excess of estimated fair value over carrying value (“headroom”) for the Nutrition reporting unit at the beginning of 2020, the decrease in the estimated fair value of the Nutrition reporting unit during the first quarter of 2020 resulted in an impairment of the carrying value of goodwill for the Nutrition reporting unit, and we recorded a $119.5 million goodwill impairment loss (see Note 5). For the Healthcare reporting unit, the fair value of the reporting unit exceeded its carrying amount, and we determined that the carrying value of goodwill was not impaired. Also during the first quarter of 2020, we estimated the fair value of indefinite-lived intangible assets, which consisted of two tradenames (the Nutrisystem tradename and the SilverSneakers tradename), using the relief-from-royalty method, which required significant assumptions such as the long-term growth rate of future revenues, the royalty rate for such revenue, and a discount rate. Changes in these estimates and assumptions could materially affect the estimate of fair value for the tradenames. Similar to the goodwill impairment analysis described above, the discount rate used in the estimation of fair value of the tradenames was adversely impacted by the changing market and economic conditions discussed above, resulting in a lower estimated fair value for each tradename. D ue to an impairment loss recorded in the fourth quarter of 2019 related to the Nutrisystem tradename and goodwill, the estimated fair value of the Nutrisystem tradename was equal to its carrying value at the beginning of 2020. The decrease in the estimated fair value of the Nutrisystem tradename during the first quarter of 2020 resulted in an impairment of the tradename, and we recorded an $80.0 million impairment loss related to the Nutrisystem tradename. Based on our impairment assessment of the SilverSneakers tradename, we determined that the carrying value of the tradename was not impaired as of the measurement date (see Note 5). On October 18, 2020, we accepted an offer to sell the Nutrition business unit for $575.0 million (subject to the terms and conditions set forth in the Purchase Agreement), which indicated that the fair value for the Nutrition business unit was below its carrying value as of September 30, 2020. We performed an impairment assessment in accordance with the held and used model and determined that the fair values of all assets and liabilities allocated to the Nutrition segment recorded an impairment million for the third quarter of 2020 related to goodwill allocated to the Nutrition segment (see Note 5).

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	1 3 . Derivative Instruments and Hedging Activities We use derivative instruments to manage differences in the amount, timing, and duration of our known or expected cash payments related to our outstanding debt (i.e., interest rate risk) erivatives are designated and qualify as a hedge of the exposure to variability in expected future cash flows and are therefore considered cash flow hedges. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting , and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting . We classify cash flows from settlement of our cash flow hedges in the same category as the cash flows from the related hedged items, generally within the operating activities in the consolidated statements of cash flows. We do not use derivatives for trading or speculative purposes and currently do not have any derivatives that are not designated as hedges . Cash Flow Hedges of Interest Rate Risk Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps as part of our interest rate risk management strategy. The counterparties to the interest rate swap agreements expose us to credit risk in the event of nonperformance by such counterparties. However, at September 30, 2020 Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for our making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. In May 2019, we entered into eight amortizing interest rate swap agreements, each of which matures in May 2024. Under these agreements, we receive a variable rate of interest based on LIBOR, and we pay a fixed rate of interest equal to approximately 2.2% plus a spread (see Note 10). As of September 30, 2020, these interest rate swap agreements had current notional amounts totaling $800.0 million. We record derivatives that are designated and qualify as cash flow hedges at estimated fair value in the consolidated balance sheet, with the related gains and losses recorded in accumulated other comprehensive income or loss ("accumulated OCI") and subsequently reclassified into interest expense in the same period(s) during which the hedged transaction affects earnings Amounts reported in accumulated OCI related to derivatives will be reclassified to interest expense as we make interest payments on our variable-rate debt. The estimated gross fair values of derivative instruments and their classification on the consolidated balance sheet at September 30, 2020 and December 31, 2019 were as follows: (In thousands) September 30, 2020 December 31, 2019 Liabilities: Derivatives designated as hedging instruments: Current portion of long-term liabilities $ 15,140 $ 4,947 Other long-term liabilities 25,443 11,291 $ 40,583 $ 16,238 The following table presents the effect of cash flow hedge accounting on accumulated OCI as of September 30 (In thousands) For the Three Months Ended For the Nine Months Ended Derivatives in Cash Flow Hedging Relationships September 30, 2020 September 30, 2019 September 30, 2020 September 30, 2019 Loss related to effective portion of derivatives recognized in accumulated OCI, gross of tax effect $ 396 $ 5,076 $ 33,168 $ 21,220 Gain (loss) related to effective portion of derivatives reclassified from accumulated OCI to interest expense, gross of tax effect $ (4,219 ) $ 39 $ (8,823 ) $ 199

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	14. Earning (Loss) Pe Sha r We use the two-class method to calculate earnings per share as the unvested restricted stock awards outstanding under our equity incentive plan are participating shares with nonforfeitable rights to dividends. Under the two-class method, we compute earnings per share of Common Stock by dividing the sum of distributed earnings to common stockholders (currently not applicable as we do not pay dividends) and undistributed earnings allocated to common stockholders by the weighted average number of outstanding shares of Common Stock for the period. In applying the two-class method, we allocate undistributed earnings to both shares of Common Stock and participating securities based on the number of weighted average shares outstanding during the period. Any undistributed losses are not allocated to unvested restricted stock as the restricted stockholders are not obligated to share in the losses.

Subsequent Events [Abstract]
Subsequent Events	17. Subsequent Events On October 18, 2020, we entered into the Stock Purchase Agreement with Kainos. Upon the terms and subject to the conditions set forth in the Purchase Agreement, the Company will sell to Kainos all of the issued and outstanding capital stock of Nutrisystem, for a cash purchase price of $575.0 million, subject to customary adjustments. The consummation of the transactions contemplated by the Purchase Agreement, which will result in the disposition of our Nutrition Business, is expected to occur in the fourth quarter of 2020. The Nutrition Business is comprised of Nutrisystem’s legacy business and includes the Nutrisystem and South Beach Diet programs (see Notes 5 and 12). Because management did not have the authority to commit to a plan to sell the Nutrition Business at September 30, 2020, we concluded that the held for sale criteria was not met in the third quarter of 2020. Upon obtaining Board approval to sell the Nutrition Business on October 18, 2020, we met all of the criteria to classify the Nutrition Business as held for sale. We have concluded that the disposition of the Nutrition Business represents a strategic shift that will have a major effect on our operations and financial results. Accordingly, we expect to report the Nutrition Business as discontinued operations for the fourth quarter of 2020 and beyond. Based on the accepted purchase price of $575.0 million for the Nutrition Business in October 2020, we concluded that the fair value for the Nutrition business unit was below its carrying value as of September 30, 2020. We performed an impairment assessment in accordance with the held and used model and determined that the fair value of all assets and liabilities allocated to the Nutrition segment exceeded their carrying amounts as of September 30, 2020, except for goodwill. As a result, we million for the third quarter of 2020 related to goodwill allocated to the Nutrition segment.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation and Recent Developments	Our financial statements and accompanying notes are prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). In our opinion, the accompanying consolidated financial statements of Tivity Health ® ® By their nature, estimates are subject to an inherent degree of uncertainty. Due We have reclassified certain items in prior periods to conform to current classifications. Following the acquisition of Nutrisystem (the “Merger”), we organize and manage our operations within two reportable segments, based on the types of products and services they offer: Healthcare and Nutrition. The Healthcare segment is comprised our legacy business and includes SilverSneakers ® senior fitness, Prime ® Fitness, WholeHealth Living ® and Wisely Well TM ® and the South Beach Diet ® programs. We have omitted certain financial information that is normally included in financial statements prepared in accordance with U.S. GAAP but that is not required for interim reporting purposes. You should read the accompanying consolidated financial statements in conjunction with the financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2019. Recent Developments On October 18, 2020, we entered into a Stock Purchase Agreement (“Purchase Agreement”) with Kainos NS Holdings LP, a Delaware limited partnership (“Parent”), and KNS Acquisition Corp., a Delaware corporation and indirect wholly owned subsidiary of Parent (“Purchaser,” and collectively with Parent, “Kainos”). Upon the terms and subject to the conditions set forth in the Purchase Agreement, the Company will sell to Kainos all of the issued and outstanding capital stock of Nutrisystem, for a cash purchase price of $575.0 million, subject to customary adjustments. The consummation of the transactions contemplated by the Purchase Agreement, which will result in the disposition of our Nutrition business (the “Nutrition Business”), is expected to occur in the fourth quarter of 2020. The Nutrition Business is comprised of Nutrisystem’s legacy business and includes the Nutrisystem and South Beach Diet programs (see Note 17). COVID-19 In January 2020, the Secretary of the U.S. Department of Health and Human Services (“HHS”) declared a national public health emergency due to a novel strain of coronavirus, which causes the disease known as “COVID-19.” In March 2020, the World Health Organization characterized the outbreak of COVID-19 as a global pandemic, and COVID-19 continues to spread throughout the United States and other countries. Many state and local governments, together with public health officials, have recommended and mandated precautions to mitigate the spread of COVID-19, including ordering closure of certain businesses and imposing stay-at-home orders and social distancing guidelines for individuals. Such measures have resulted in significantly reduced demand for many businesses that have continued in operation. By March 31, 2020, substantially all of the fitness centers in our national network were temporarily closed, which had an adverse impact on the results of operations in our Healthcare segment for the first quarter of 2020 because a significant member visits to a fitness partner location A substantial number of our fitness partner locations remained closed through April, with some locations reopening in May and additional locations reopening in June and throughout the third quarter of 2020. For the month of September 2020 , approximately % of our fitness partner locations reported at least one visit from our SilverSneakers program. For the second and third quarter s of 2020, t he average monthly total participation level s of our SilverSneakers members were significantly below historical levels, and we also experienced a decline in paid subscribers for Prime Fitness, each of which adversely impact ed revenues in our Healthcare segment. We do not believe that COVID-19-related developments had a material impact on the results of operations or cash flows of our Nutrition segment for the first, second, or third quarters of 2020. While overall we did not experience any significant disruptions, interruptions, or increased costs related to our supply chain, inventory, or distribution channels as a result of COVID-19, we experienced delays in fulfilling orders for our Nutrition segment’s products at certain of our warehouses due to some employees of our fulfillment provider testing positive for COVID-19 We have taken a number of actions in response to the pandemic, including the following: • Given the continued uncertainty surrounding COVID-19, in March 2020, we borrowed $75 million under our Revolving Credit Facility as a precautionary measure to increase our cash position and maintain financial flexibility. We repaid such $75 million in full in June 2020. As of September 30, 2020, outstanding debt under our credit agreement was $974.8 million, and we had $56.4 million of cash and cash equivalents. In the third quarter of 2020, we repaid $39.7 million of principal on the term loans under our credit agreement, resulting in our next required quarterly installment being due in March 2022. As of September 30, 2020, we had working capital of $4.8 million. While the COVID-19 pandemic has created significant uncertainty as to general economic and market conditions for the remainder of 2020 and beyond, as of the date of this report, we believe our cash on hand, expected cash flows from operations, net proceeds from the expected sale of our Nutrition segment, and anticipated available credit under the Credit Agreement (as defined below) will be sufficient to fund our operations, principal and interest payments, and capital expenditures for the next 12 months • We have taken a variety of measures to ensure the availability and functioning of our critical infrastructure, to promote the safety and security of our employees and to support the communities in which we operate. These measures include implementing remote working arrangements for employees where practicable. We are following public and private sector policies and initiatives to reduce the transmission of COVID-19, such as the imposition of travel restrictions, the promotion of social distancing, and the adoption of work-from-home arrangements. • We are focused on preserving our liquidity and managing our cash flow, including, but not limited to, managing our working capital, optimizing tax savings under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) and other COVID-19-related legislation, curtailing capital expenditures, reducing discretionary spending, and reducing compensation costs. o In April 2020, we furloughed 13% of our approximately 1,000 employees. In June 2020, some of these furloughed employees’ positions were eliminated (in addition to other position eliminations, resulting in approximately 8% of our employees being terminated), and we extended the furlough for substantially all of the remaining furloughed employees through the end of 2020. Also in June 2020, we placed an additional 2% of our total employees on furlough through the end of 2020. o Also in April 2020, the Compensation Committee of the Company’s Board of Directors (the “Board”) approved a 25% reduction in base salary for the Company’s executive officers and certain other employees for the period from April 20, 2020 through August 23, 2020. In June 2020, the Compensation Committee determined to extend such reductions in base salary through December 31, 2020 . Additionally, the Board approved a 100% reduction in the annual cash retainer and annual committee retainers payable to non-management members of the Board who stood for reelection at the 2020 Annual Meeting of Stockholders (except for Daniel G. Tully who did not receive compensation for his service on the Board) for a period of four months , beginning May 1, 2020. In June 2020, the Board determined to extend such reduction in cash compensation to the Board through December 31, 2020. o Effective at the end of July 2020, the Compensation Committee suspended the Company matching contribution to the Company’s 401(k) plan. As a result of the COVID-19 pandemic, in March 2020, we experienced a significant decline in the Company’s market capitalization and in the actual and forecasted operating results of our Healthcare segment, in addition to the unfavorable change in market conditions which consist of the Nutrisystem tradename and the SilverSneakers tradename) including $80.0 million related to the Nutrisystem tradename and $119.5 million related to goodwill allocated to the Nutrition segment. There were no impairment triggers during the second quarter of 2020 related to our goodwill or indefinite-lived intangible assets. During the third quarter of 2020, we recorded an additional impairment loss of $66.2 million related to goodwill allocated to the Nutrition segment (see Note 12).
Recent Relevant Accounting Standards	In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04, “ Reference Rate Reform (“ASC 848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting”. ASC 848 contains temporary optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform, such as a transition away from the use of LIBOR. ASC 848 was effective for the Company as of January 1, 2020. The provisions of ASC 848 are available through December 31, 2022, at which time the reference rate replacement activity is expected to have been completed. The provisions of ASC 848 must be applied at a Topic, Subtopic or Industry Subtopic level for all transactions other than derivatives, which may be applied at a hedging relationship level. The accounting relief provided by ASC 848 is applicable only to legacy contracts if the amendments made to the agreements are solely for reference rate reform activities. Modifications that are unrelated to reference rate reform will scope out a given contract. ASC 848 allows for different elections to be made at different points in time, and the timing of those elections will be documented as applicable. For the avoidance of doubt, we intend to reassess the elections of optional expedients and exceptions included within ASC 848 related to our hedging activities and will document the election of these items on a quarterly basis. In March 2020, we elected the expedient that allows us to assume that our hedged interest payments are probable of occurring regardless of any expected modification in their terms related to reference rate reform. In addition, we have the option to change the method of assessing effectiveness upon a change in the critical terms of the derivative or the hedged transactions and upon the end of relief under ASC 848. In June 2020, we elected to (i) continue the method of assessing effectiveness as documented in the original hedge documentation and (ii) apply the expedient wherein the reference rate on the hypothetical derivative matches the reference rate on the hedging instrument. We will also apply the aforementioned elections to any future designated cash flow hedging relationship. In October 2018, the FASB issued ASU 2018-16, "Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (“SOFR”) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes" (“ASU 2018-16”), which adds the OIS rate based on SOFR as a U.S. benchmark interest rate to facilitate the LIBOR to SOFR transition and provide lead time for entities to prepare for changes to interest rate risk hedging strategies. ASU 2018-16 is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. As of September 30, 2020, the benchmark interest rate in our existing interest rate swap agreements is LIBOR. The adoption of this standard did not have an impact on our financial position, results of operations, or cash flows . In January 2017, the FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other” (“ASU 2017-04”), which simplifies the subsequent measurement of goodwill by eliminating step two from the goodwill impairment test. ASU 2017-04 is effective for annual and interim impairment tests in fiscal years beginning after December 15, 2019 and is required to be applied prospectively. Early adoption is allowed for annual goodwill impairment tests performed on testing dates after January 1, 2017. We adopted ASU 2017-04 on October 1, 2019. As further discussed in Note 12, we recorded impairment losses related to goodwill during the fourth quarter of 2019 and the first and third quarter s of 2020 . In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”), which changes the fair value measurement disclosure requirements of ASC 820. ASU 2018-13 is effective for fiscal years beginning on or after December 15, 2019, including interim periods therein, and is generally required to be applied retrospectively, except for certain components that are to be applied prospectively. The adoption of this standard did not have a material impact on our consolidated financial statements and related disclosures In August 2018, the FASB issued ASU No. 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” which requires implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement. This standard is effective for annual periods beginning after December 15, 2019, and interim periods within those fiscal years. The adoption of this standard did not have a material impact on our consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”), which requires companies to measure credit losses for financial assets held at the reporting date utilizing a methodology that reflects current expected credit losses over the lifetime of such assets. ASU 2016-13 was effective for the Company on January 1, 2020 and is generally required to be applied using the modified retrospective approach, with limited exceptions for specific instruments. The adoption of this standard did not have a material impact on our consolidated financial statements and related disclosures.
