Business Combinations [Abstract]
Acquisitions, Dispositions and Other Transactions	Acquisitions, Dispositions and Other Transactions During the period from January 1, 2019 through September 30, 2020, the Company acquired 27 communities that the Company formerly leased, disposed of 21 owned communities (including the conveyance of five communities to Ventas discussed below), and sold its ownership interest in its unconsolidated entry fee CCRC Venture (the "CCRC Venture") with Healthpeak Properties, Inc. ("Healthpeak"), and the Company's triple-net lease obligations on 14 communities were terminated. The acquisitions of formerly leased communities include the 18 communities acquired from Healthpeak described below and eight communities acquired pursuant to the exercise of a purchase option for a purchase price of $39.3 million, all of which occurred during the three months ended March 31, 2020. During the three months ended September 30, 2020, the Company acquired one formerly leased community pursuant to the exercise of a purchase option for a purchase price of $25.0 million. As of September 30, 2020, the Company owned 350 communities, leased 302 communities, and managed 74 communities. One unencumbered community in the CCRCs segment was classified as held for sale, resulting in $8.3 million being recorded as assets held for sale as of September 30, 2020. The closings of the various pending and expected transactions described within this note are, or will be, subject to the satisfaction of various closing conditions, including (where applicable) the receipt of regulatory approvals. However, there can be no assurance that the transactions will close or, if they do, when the actual closings will occur. Dispositions of Owned Communities During the nine months ended September 30, 2020, the Company completed the sale of two owned communities (excluding the conveyance of five communities to Ventas, discussed below) for cash proceeds of $38.1 million, net of transaction costs, and recognized a net gain on sale of assets of $2.7 million. During the year ended December 31, 2019, the Company completed the sale of 14 owned communities for cash proceeds of $85.4 million, net of transaction costs, and recognized a net gain on sale of assets of $5.5 million. The Company utilized a portion of the cash proceeds from the asset sales to repay approximately $5.1 million of associated mortgage debt and debt prepayment penalties. These dispositions included the sale of eight communities during the nine months ended September 30, 2019 for which the Company received cash proceeds of $44.1 million, net of transaction costs and recognized a net gain on sale of assets of $0.9 million for the nine months ended September 30, 2019. Ventas Lease Restructuring On July 26, 2020 (the "Effective Date"), the Company entered into definitive agreements with Ventas in connection with the restructuring of the Company’s lease arrangements with Ventas, including a Master Transaction Letter Agreement (the "Master Agreement"). Pursuant to the Master Agreement: •On the Effective Date the parties entered into the Amended and Restated Master Lease and Security Agreement (the "Master Lease") and Amended and Restated Guaranty (the "Guaranty"), which amended and restated the prior Master Lease and Security Agreement and prior Guaranty, each dated as of April 26, 2018 and as amended from time to time. Pursuant to the Master Lease, the Company continues to lease 120 communities for an aggregate initial annual minimum rent of approximately $100 million, which reflects a reduction of approximately $83 million of annual minimum rent in effect prior to the transaction. Effective on January 1 of each lease year, beginning January 1, 2022, the annual minimum rent will be subject to a 3% escalator. The initial term of the Master Lease ends December 31, 2025, with two 10-year extension options available to the Company. The annual minimum rent for the initial lease year of any such renewal term will be the greater of the fair market rental of the communities or the increased annual minimum rent for such lease year applying the foregoing 3% escalator. The Master Lease removed the prior provision that would have automatically extended the initial term in the event of the consummation of a change of control transaction by the Company. The Master Lease requires the Company to spend (or escrow with Ventas) a minimum of $1,500 per unit on a community-level basis and $3,600 per unit on an aggregate basis of all communities, in each case per 24-month period ending December 31 during the lease term, commencing with the 24-month period ending December 31, 2021. In addition, Ventas has agreed to fund costs associated with certain pre-approved capital expenditure projects in the aggregate amount of up to $37.8 million. Upon disbursement of such expenditures, the annual minimum rent under the Master Lease will increase by the amount of the disbursement multiplied by 50% of the sum of the then current 10-year treasury note rate and 4.5%. The transaction agreements with Ventas further provide that the Master Lease and certain other agreements between the parties will be cross-defaulted. The Company’s subsidiaries’ obligations under the Master Lease are guaranteed at the parent level pursuant to the Guaranty. The Guaranty removed the prior requirements that the Company satisfy, at the parent level, financial covenants and that the Company maintain a security deposit with Ventas. The Guaranty also removed the prior right of Ventas to terminate the Master Lease on the basis of parent level financial covenants. Pursuant to the terms of the Guaranty, the Company may consummate a change of control transaction without the need for consent of Ventas so long as certain objective conditions are satisfied, including the post-transaction guarantor’s maintaining a minimum tangible net worth of at least $600.0 million, having minimum levels of operational experience and reputation in the senior living industry, and paying a change of control fee of $25.0 million to Ventas. The Guaranty removed the prior provisions that would have required that such post-transaction guarantor satisfy a maximum leverage ratio level, that the Company fund additional capital expenditures, and that the Company extend the term upon the occurrence of the change in control transaction. Under the terms of the Guaranty, commencing January 1, 2024 (and until such time (if any) as the Company exercises its lease term extension option with respect to the Master Lease), Ventas shall have the right to terminate the Master Lease (with respect to one or more communities), provided that the trailing twelve month coverage ratio of each such community is less than 0.9x and provided further that the removal and termination of any such communities does not result in a portfolio coverage ratio with respect to the remaining communities in the Master Lease that is less than the portfolio coverage ratio prior to such removal and termination. •On the Effective Date, the Company entered into a Second Amended and Restated Omnibus Agreement with Ventas, which provides that if a default occurs and is continuing under certain other material leases or under certain material financings and if the same continues beyond the permitted cure period or the applicable landlord or lender exercises any material remedies, Ventas shall have the right to transition all or a portion of the communities from the Master Lease to a management arrangement with the Company pursuant to a market management agreement (which is terminable by either party). Notwithstanding the foregoing, Ventas may only transition one or more communities from the Master Lease to a management arrangement if such transition does not result in a portfolio coverage ratio with respect to the remaining communities in the Master Lease that is less than the portfolio coverage ratio prior to such transition. •On the Effective Date, the Company conveyed five owned communities to Ventas in full release and satisfaction of $78.4 million principal amount of indebtedness secured by the communities. Upon closing, the parties entered into new terminable, market rate management agreements pursuant to which the Company manages the communities. The Company also paid to Ventas $115.0 million in cash, released all security deposits under the former guaranty (which included the release of a $42.4 million deposit held by Ventas and the payment of $4.2 million in cash as settlement of the amount of letters of credit), and issued a $45.0 million unsecured interest-only promissory note to Ventas. The initial interest rate of the promissory note is 9.0% per annum and will increase by 0.50% on each anniversary of the date of issuance. The Company may prepay the outstanding principal amount in whole or in part at any time without premium or penalty. The promissory note matures on the earlier of December 31, 2025 or the occurrence of a change of control transaction (as defined in the Guaranty). •On the Effective Date, the Company issued to Ventas a warrant (the "Warrant") to purchase 16.3 million shares of the Company’s common stock, $0.01 par value per share, at a price per share of $3.00. The Warrant is exercisable at Ventas' option at any time and from time to time, in whole or in part, until December 31, 2025. The exercise price and the number of shares issuable on exercise of the Warrant are subject to certain anti-dilution adjustments, including for cash dividends, stock dividends, stock splits, reclassifications, non-cash distributions, certain repurchases of common stock and business combination transactions. To the extent that the number of shares owned by Ventas (including shares underlying the Warrant) would be more than 9.6% of the total combined voting power of all the Company’s classes of capital stock or of the total value of shares of all the Company’s classes of capital stock (the “Ownership Cap”) (other than as a result of actions taken by Ventas), the Company would generally be required to repurchase the number of shares necessary to avoid Ventas exceeding the Ownership Cap unless Ventas makes an election to require the Company to pay Ventas cash in lieu of issuing shares pursuant to the Warrant in excess of the Ownership Cap. The Warrant and the shares issuable upon exercise thereof have not been registered under the Securities Act of 1933, as amended, and were issued in a private placement pursuant to Section 4(a)(2) thereof. On the Effective Date, the parties entered into a Registration Rights Agreement, pursuant to which Ventas and its permitted transferees are entitled to certain registration rights. Pursuant to the terms of the agreement, the Company filed a shelf registration statement with the SEC with respect to the shares of common stock underlying the Warrant, which was declared effective on August 17, 2020. Ventas is entitled to customary underwritten offering, piggyback, and additional demand registration rights with respect to the shares underlying the Warrant. As a result of the modification of the community leases with Ventas, the Company reduced the carrying amount of lease obligations and assets under leases by $370.0 million and $159.5 million, respectively, in the three months ended September 30, 2020. As the Company's community leases do not contain an implicit rate, the Company utilized its incremental borrowing rate based on information available on the Effective Date to determine the present value of remaining lease payments for the community leases with Ventas. Additionally, the results and financial position of the five communities conveyed to Ventas were deconsolidated from the Company's financial statements prospectively as of the Effective Date. As of the Effective Date, the Warrant was recognized as a component of stockholders’ equity at its estimated fair value of $22.9 million. The Company’s net cash provided by operating activities for the nine months ended September 30, 2020 includes the $119.2 million one-time cash lease payment made to Ventas in connection with its lease restructuring transaction effective July 26, 2020. See Note 13 for more information regarding the adjustments to the Company’s condensed consolidated balance sheet as a result of this transaction. Healthpeak CCRC Venture and Master Lease Transactions On October 1, 2019, the Company entered into definitive agreements, including a Master Transactions and Cooperation Agreement (the "MTCA") and an Equity Interest Purchase Agreement (the "Purchase Agreement"), providing for a multi-part transaction with Healthpeak. The parties subsequently amended the agreements to include one additional entry fee CCRC community as part of the sale of the Company's interest in the CCRC Venture (rather than removing the community from the CCRC Venture for joint marketing and sale). The components of the multi-part transaction include: •CCRC Venture Transaction. Pursuant to the Purchase Agreement, on January 31, 2020, Healthpeak acquired the Company's 51% ownership interest in the CCRC Venture, which held 14 entry fee CCRCs, for a purchase price of $289.2 million, net of a $5.9 million post-closing net working capital adjustment paid to Healthpeak during the three months ended June 30, 2020 (representing an aggregate valuation of $1.06 billion less portfolio debt, subject to a net working capital adjustment). The $289.2 million of cash received from Healthpeak is presented within net cash used in investing activities for the nine months ended September 30, 2020. The Company recognized a $369.8 million gain on sale of assets for the nine months ended September 30, 2020, and the Company derecognized the net equity method liability for the sale of the ownership interest in the CCRC Venture. At the closing, the parties terminated the Company's existing management agreements on the 14 entry fee CCRCs, Healthpeak paid the Company a $100.0 million management agreement termination fee, and the Company transitioned operations of the entry fee CCRCs to a new operator. The Company recognized $100.0 million of management fee revenue for the three months ended March 31, 2020 for the management termination fee. Prior to the January 31, 2020 closing, the parties moved the remaining two entry fee CCRCs into a new unconsolidated venture on substantially the same terms as the CCRC Venture to accommodate the sale of such two communities expected to occur in 2021. Subsequent to these transactions, the Company will have exited substantially all of its entry fee CCRC operations. •Master Lease Transactions. Pursuant to the MTCA, on January 31, 2020, the parties amended and restated the existing master lease pursuant to which the Company continues to lease 25 communities from Healthpeak, and the Company acquired 18 formerly leased communities from Healthpeak, at which time the 18 communities were removed from the master lease. At the closing, the Company paid $405.5 million to acquire such communities and to reduce its annual rent under the amended and restated master lease. The $405.5 million of cash paid to Healthpeak and $1.7 million of direct acquisition costs are presented within net cash used in investing activities for the nine months ended September 30, 2020. The Company funded the community acquisitions with $192.6 million of non-recourse mortgage financing and the proceeds from the multi-part transaction. In addition, Healthpeak has agreed to terminate the lease for one leased community. With respect to the continuing 24 communities, the Company's amended and restated master lease: (i) has an initial term to expire on December 31, 2027, subject to two extension options at the Company's election for ten years each, which must be exercised with respect to the entire pool of leased communities; (ii) the initial annual base rent for the 24 communities is $41.7 million and is subject to an escalator of 2.4% per annum on April 1st of each year; and (iii) Healthpeak has agreed to make available up to $35.0 million for capital expenditures for a five-year period related to the 24 communities at an initial lease rate of 7.0%. As a result of the community acquisition transaction, the Company recognized a $19.7 million gain on debt extinguishment during the three months ended March 31, 2020 and derecognized the $105.1 million carrying amount of financing lease obligations for eight communities which were previously subject to sale-leaseback transactions in which the Company was deemed to have continuing involvement.
