Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Organization	Basis of Presentation and Organization General. AlerisLife Inc., collectively with its consolidated subsidiaries, the Company, we, us or our, is a holding company incorporated in Maryland. Substantially all of our business is conducted by our two segments: (i) our residential segment through our Five Star Senior Living, or Five Star, brand and (ii) our lifestyle services segment primarily through our Ageility Physical Therapy Solutions and Ageility Fitness, or collectively Ageility, brands, as well as Windsong Home Health. The accompanying condensed consolidated financial statements of the Company are unaudited. Certain information and disclosures required by the rules and regulations of the Securities and Exchange Commission, or SEC, and the U.S. Generally Accepted Accounting Principles, or GAAP, for complete financial statements have been condensed or omitted pursuant to SEC rules and regulations related to interim financial statements. We believe the disclosures made are adequate to make the information presented not misleading. As of June 30, 2022, through our residential segment, we owned and operated or managed, 140 senior living communities located in 28 states with 19,973 living units, including 10,460 independent living apartments and 9,513 assisted living suites, which includes 1,817 Bridge to Rediscovery memory care units. We managed 120 of these senior living communities (17,886 living units) for Diversified Healthcare Trust, or DHC, and owned 20 of these senior living communities (2,087 living units). The foregoing numbers exclude living units categorized as out of service. Our lifestyle services segment provides a comprehensive suite of lifestyle services including Ageility rehabilitation and fitness, Windsong Home Health and other home based, concierge services at senior living communities we own and operate or manage as well as at unaffiliated senior living communities. As of June 30, 2022, Ageility operated ten inpatient rehabilitation clinics in senior living communities owned by DHC that are not operated by Five Star. As of June 30, 2022, Ageility operated 202 outpatient rehabilitation locations, of which 108 were located at Five Star operated senior living communities and 94 were located within senior living communities not operated by Five Star. The accompanying financial statements should be read in conjunction with the financial statements and notes contained in our Annual Report on Form 10-K for the year ended December 31, 2021, or Annual Report. In the opinion of our management, all adjustments, which include only normal recurring adjustments considered necessary for a fair presentation, have been included. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated. Our operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Estimates and Assumptions. The preparation of these condensed consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that may affect the amounts reported in these condensed consolidated financial statements and related notes. Significant estimates in our condensed consolidated financial statements relate to revenue recognition, including contractual allowances and implicit price concessions, recoverability of long-lived assets, self-insurance reserves and estimates concerning our provision for income taxes or valuation allowance related to deferred tax assets. Our actual results could differ from our estimates. We periodically review estimates and assumptions, and we reflect the effects of changes, if any, in the condensed consolidated financial statements in the period that they are determined. There have been no changes to our significant accounting policies disclosed in our Annual Report. See Note 2 to our Consolidated Financial Statements included in Part IV, Item 15 of our Annual Report. Recently Issued Accounting Pronouncements Not Yet Adopted. In June 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2016-13, Financial Instruments-Credit Losses (Topic 326) , which requires a financial asset or a group of financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. This ASU eliminates the probable initial recognition threshold and instead requires reflection of an entity’s current estimate of all expected credit losses. In addition, this ASU amends the current other-than-temporary impairment model for available for sale debt securities. The length of time that the fair value of an available for sale debt security has been below the amortized cost will no longer impact the determination of whether a credit loss exists and credit losses will now be limited to the difference between a security’s amortized cost basis and its fair value. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses , which amends the transition and effective date for nonpublic entities and smaller reporting companies, such as us, and clarifies that receivables arising from operating leases are not in the scope of this ASU. In November 2019, the FASB issued ASU No. 2019-11, Codification Improvements to Topic 326 , Financial Instruments-Credit Losses , which clarifies guidance around how to report expected recoveries. Entities will apply the provisions of the ASU as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. This ASU is effective for smaller reporting companies for reporting periods beginning after December 15, 2022. We are currently assessing the potential impact that the adoption of this ASU (and the related clarifying guidance issued by the FASB) will have on our condensed consolidated financial statements. In June 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820) - Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions , which clarifies that a contractual sale restriction prohibiting the sale of an equity security is a characteristic of the reporting entity holding the equity security and is not included in the equity security's unit of account. Accordingly, an entity should not consider the contractual sale restriction when measuring the equity security’s fair value. In addition, the ASU prohibits an entity from recognizing a contractual sale restriction as a separate unit of account. This ASU will be effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. We are currently assessing the potential impact that the adoption of this ASU will have on our condensed consolidated financial statements.

As a result, we recorded an impairment on certain furniture, fixtures and building improvements for the three and six months ended June 30, 2021 of $890, which is recorded in other residential expenses in the condensed consolidated statement of operations. Insurance proceeds received for property damages to the previously leased community caused by the fire of $1,500 were subsequently transferred to PEAK. No impairment charges were recorded for the three and six months ended June 30, 2022. We recorded depreciation expense relating to our property and equipment of $2,757 and $2,699 for the three months ended June 30, 2022 and 2021, respectively, and $5,442 and $5,390 for the six months ended June 30, 2022 and 2021, respectively.

Income Taxes	Income TaxesWe recognized a benefit for income taxes of $9 and a provision for income taxes of $68 for the three and six months ended June 30, 2022, respectively, and a provision for income taxes of $158 and $358 for the three and six months ended June 30, 2021, respectively. The benefit and provision for income taxes for the three and six months ended June 30, 2022 and 2021 is related to state income taxes.We previously determined it was more likely than not that a majority of our net deferred tax assets would not be realized and concluded that a valuation allowance was required, which eliminated the majority of our net deferred tax assets recorded in our condensed consolidated balance sheets. In the future, if we believe that we will more likely than not realize the benefit of these deferred tax assets, we will adjust our valuation allowance and recognize an income tax benefit, which may affect our results of operations.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share	Net Income (Loss) Per Share Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of outstanding common shares outstanding during the period. When applicable, net income (loss) per share—diluted reflects the more dilutive earnings per share using the weighted average number of our common shares calculated using the two-class method, or the treasury stock method. The following table provides a reconciliation of the weighted average number of common shares used in the calculation of basic and diluted net loss per share (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Weighted average shares outstanding—basic 31,810 31,552 31,799 31,541 Effect of dilutive securities: unvested share awards — — — — Weighted average shares outstanding—diluted (1) 31,810 31,552 31,799 31,541 _______________________________________ (1) For the three months ended June 30, 2022 and 2021, 1,415 and 150 of our unvested common shares were not included in the calculation of net loss per share—diluted because to do so would have been anti-dilutive. For the six months ended June 30, 2022 and 2021, 1,173 and 141, respectively, of our unvested common shares were not included in the calculation of the net loss per share—diluted because to do so would have been antidilutive.

Cash equivalents are reported in our condensed consolidated balance sheets as cash and cash equivalents and current and long-term restricted cash and cash equivalents. Cash equivalents include $20,363 and $23,546 of balances that were restricted at June 30, 2022 and December 31, 2021, respectively. In addition to the cash equivalents of $37,564 and $26,417 at June 30, 2022 and December 31, 2021, respectively, reflected above, there were cash balances of $66,259 and $64,116 and restricted cash balances of $2,513 and $2,406 at June 30, 2022 and December 31, 2021, respectively. (2) The fair value of our equity investments is readily determinable. During the six months ended June 30, 2022 and 2021, we received gross proceeds of $521 and $741, respectively, in connection with the sales of equity investments and recorded gross realized gains totaling $0 and $175, respectively, and gross realized losses totaling $45 and $0, respectively. (3) As of June 30, 2022, our debt investments, which are classified as available for sale, had a fair value of $8,733 with an amortized cost of $9,223; the difference between the fair value and amortized cost amounts resulted from net unrealized losses of $490, inclusive of unrealized gains of $6. As of December 31, 2021, our debt investments had a fair value of $10,375 with an amortized cost of $10,079; the difference between the fair value and amortized cost amounts resulted from net unrealized gains of $296, inclusive of unrealized losses of $10. Debt investments include $7,081 and $6,907 of balances that were restricted as of June 30, 2022 and December 31, 2021, respectively. At June 30, 2022, 86 debt investments we held, with a fair value of $7,383, had been in a loss position for less than 12 months and one of the debt investments we held, with a fair value of $49, had been in a loss position for greater than 12 months. We do not believe these investments are impaired primarily because they have not been in a loss position for an extended period of time, the financial conditions of the issuers of these investments remain strong with solid fundamentals as of June 30, 2022, we do not intend to sell the investments and it is not more likely than not that we will be required to sell the investments before recovery, and other factors that support our conclusion that the loss is temporary. During the six months ended June 30, 2022 and 2021, we received gross proceeds of $705 and $1,294, respectively, in connection with the sales of debt investments and recorded gross realized losses of $(3) and $0, respectively, and gross realized gains of $1 and $18, respectively, during the six months ended June 30, 2022 and 2021. We record gains and losses on the sales of these investments using the specific identification method. The amortized cost basis and fair value of available for sale debt securities at June 30, 2022, by contractual maturity, are shown below: Amortized Cost Fair Value Due in one year or less $ 997 $ 1,000 Due after one year through five years 4,353 4,240 Due after five years through ten years 2,835 2,592 Due after ten years 1,038 901 Total $ 9,223 $ 8,733 Our financial assets (which include cash equivalents and investments) have been valued at the transaction price and subsequently valued, at the end of each reporting period, utilizing third-party pricing services or other market observable data. During the six months ended June 30, 2022, we did not change the type of inputs used to determine the fair value of any of our assets and liabilities that we measure at fair value. The carrying value of accounts receivable and accounts payable approximates fair value as of June 30, 2022 and December 31, 2021. The carrying value and fair value of our debt was $67,501 and $58,445, respectively, as of June 30, 2022 and $6,783 and $7,689, respectively, as of December 31, 2021. These are categorized in Level 3 of the fair value hierarchy. We estimate the fair value of our debt by using discounted cash flow analyses and currently prevailing market terms as of the measurement date. Non-Recurring Fair Value Measures We review the carrying value of our long-lived assets, including our right-of-use assets and property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset or asset group may not

Debt Disclosure [Abstract]
Indebtedness	Indebtedness On January 27, 2022, certain of our subsidiaries entered into a credit and security agreement, or the Credit Agreement, with MidCap Funding VIII Trust as administrative agent and a lender, or MidCap. Under the terms of the Credit Agreement, we entered into a $95,000 senior secured term loan, or the Loan, $63,000 of which was funded upon effectiveness of the Credit Agreement, including approximately $3,200 in closing costs. The remaining proceeds include $12,000 for capital improvements at senior living communities we own and an opportunity for another $20,000 that is available to us upon achieving certain financial targets. Certain of our subsidiaries are borrowers under the Credit Agreement and we and one of our subsidiaries provided a payment guarantee of up to $40,000 of the obligations under the Credit Agreement as well as non-recourse carve-outs. The guaranty is evidenced by a Guaranty and Security Agreement, or the Guaranty Agreement, made by us and one of our subsidiaries in favor of MidCap. Pursuant to the Guaranty Agreement, our subsidiary granted MidCap a security interest on all of the assets of the subsidiary. The Guaranty Agreement requires us and our subsidiary to comply with various covenants, including restricting our ability to make distributions to shareholders. The Loan is secured by real estate mortgages on 14 senior living communities owned by us, our assets and certain related collateral. The maturity date of the Loan is January 27, 2025. Subject to the payment of an extension fee of 35 basis points and meeting certain other conditions, we may elect to extend the stated maturity date of the Loan for two one year periods. We are required to pay interest on outstanding amounts at an annual base rate of the Secured Overnight Financing Rate, or SOFR, plus a term SOFR adjustment of 11 basis points (subject to a minimum base rate of 50 basis points) plus 450 basis points. The Credit Agreement requires interest only payments for the first two years and requires mandatory prepayment of the Loan on account of certain events of default. Voluntary prepayments made within 18 months of the effective date of the Loan will be subject to a prepayment fee equal to the greater of the present value of remaining interest payments relating to the principal amount being repaid or 0.50% of the outstanding balance of the Loan as of the date of prepayment. The Loan may thereafter be voluntarily prepaid without premium or penalty. The Company will be required to pay an exit fee between 1.0% and 1.5%, subject to the conditions set forth in the Credit Agreement, upon any prepayment of the Loan, which would be in addition to any prepayment fees that may be payable. The Loan provides for acceleration of payment of all amounts outstanding upon the occurrence and continuation of certain events of default, including a change of control of us, as defined in the Credit Agreement. The default rate of interest is 5.0% per annum in excess of the rate otherwise payable under the Credit Agreement. The Credit Agreement also contains a number of financial and other covenants including covenants that restrict the borrowers' ability to incur indebtedness or to pay or make distributions under certain circumstances and requires us to maintain certain financial ratios which become effective beginning March 31, 2023. The Credit Agreement also contains certain representations and warranties and reporting obligations. The annual interest rate on the Loan as of June 30, 2022 was 6.3%. We incurred aggregate interest expense related to our Loan of $1,064 and $1,779 for the three and six months ended June 30, 2022. The Loan replaced our $65,000 secured revolving credit facility, the Credit Facility, which was governed by a credit agreement with a syndicate of lenders, and was scheduled to expire on June 12, 2022, before it was terminated on January 27, 2022. No borrowings were outstanding under the Credit Facility at the time we entered into the Credit Agreement. We were required to pay a quarterly commitment fee of 0.35% per annum on the unused portion of the available capacity under our Credit Facility. We also had a letter of credit issued under the Credit Facility which was terminated when we replaced the Credit Facility with the Loan. We incurred aggregate interest expense related to our Credit Facility of $0 and $205 for the three months ended June 30, 2022 and 2021, and $28 and $458 for the six months ended June 30, 2022 and 2021, respectively. At June 30, 2022, one of our senior living communities was encumbered by a mortgage note. This mortgage note contains standard mortgage covenants. We recorded a discount in connection with the assumption of this mortgage note as part of our acquisition of the senior living community secured by this mortgage in order to record this mortgage note at its then estimated fair value. We amortize this discount as an increase in interest expense until the maturity of this mortgage note. This mortgage note requires payments of principal and interest monthly until maturity. The following table is a summary of this mortgage note as of June 30, 2022: Balance as of June 30, 2022 Contractual Stated Effective Maturity Date Monthly Lender Type $ 6,769 (1) 6.20 % 6.70 % September 2032 $ 72 Federal Home Loan Mortgage Corporation _______________________________________ (1) Contractual principal payments excluding unamortized discount of $190. We incurred interest expense, net of discount amortization, of $112 and $118 with respect to the mortgage note for the three months ended June 30, 2022 and 2021, respectively, and $227 and $240 for the six months ended June 30, 2022 and 2021, respectively. As of June 30, 2022, the required principal payments due during the next five years and thereafter under the terms of our mortgage note and Loan are as follows: Year Mortgage Loan Principal Payment Total 2022 $ 223 $ — $ 223 2023 469 — 469 2024 498 1,008 1,506 2025 531 61,992 62,523 2026 565 — 565 Thereafter 4,483 — 4,483 Total 6,769 63,000 69,769 Less: Unamortized net discount and issuance costs (190) (2,078) (2,268) Total debt 6,579 60,922 67,501 Less: Current portion of debt (429) — (429) Long-term debt $ 6,150 $ 60,922 $ 67,072 At July 29, 2022, we had one irrevocable standby letter of credit outstanding, totaling $23,850. This letter of credit, which secures our workers' compensation insurance program, is collateralized by $19,521 of cash equivalents and $4,329 of debt and equity investments. This letter of credit expires in June 2023 and is automatically extended for one-year terms unless notice of nonrenewal is provided prior to the end of the applicable term. At June 30, 2022, the cash equivalents collateralizing this letter of credit are classified as current restricted cash and cash equivalents in our condensed consolidated balance sheets, and the debt and equity investments collateralizing this letter of credit are classified as current restricted debt and equity investments in our condensed consolidated balance sheets. We believe we were in compliance with all applicable covenants under our Loan and mortgage note as of June 30, 2022.

The principal changes to the management arrangements include: • We agreed to cooperate with DHC to transition the operations for 107 senior living communities owned by DHC with approximately 7,400 living units that we then managed to other third party managers and to close one senior living community with approximately 100 living units, without payment of any termination fee to us; • DHC no longer has the right to sell up to an additional $682,000 of senior living communities managed by us and terminate our management of those senior living communities without payment of a termination fee to us upon sale; • DHC's ability to terminate the management agreement was revised: (i) to not commence until 2025; (ii) the maximum number of senior living communities that may be terminated was reduced to 10% (from 20%) of the total managed portfolio by revenue per year; and (iii) to provide that achieving less than 80% (rather than 90%) of budgeted earnings before interest, taxes, and depreciation and amortization, or EBITDA, will be required to qualify as a “Non-Performing Asset.” DHC will not be obligated to pay any termination fee to us if it exercises these termination rights; • We continue to manage for DHC 120 senior living communities we managed for it as of June 9, 2021; • We closed the 27 skilled nursing units in continuing care retirement communities, or CCRCs, that we continue to manage for DHC as independent or assisted living communities, which had 1,532 living units; • The incentive fee that we may earn in any calendar year for the senior living communities that we continue to manage for DHC will no longer be subject to a cap, any senior living communities that are undergoing a major renovation or repositioning will be excluded from the calculation of the incentive fee and the incentive fee calculation will be reset pursuant to the terms of the management agreements as a result of expected capital projects DHC is planning in the next five years; • The RMR Group LLC, or RMR, assumed oversight of major community renovation or repositioning activities at the senior living communities that we continue to manage for DHC; and • The term of our existing management agreements with DHC was extended by two years to December 31, 2036. Pursuant to the Master Management Agreement, we receive a management fee equal to 5% of the gross revenues realized at the applicable senior living communities plus reimbursement for our direct costs and expenses related to such communities. We also receive 3% of construction costs for construction projects we manage at the senior living communities we managed. We may also receive an annual incentive fee equal to 15% of the amount by which the annual EBITDA of all senior living communities on a combined basis exceeds the target EBITDA for all senior living communities on a combined basis for such calendar year. The target EBITDA for those senior living communities on a combined basis is increased annually based on the greater of the annual increase of the Consumer Price Index, or CPI, or 2%, plus 6% of any capital investments funded at the managed senior living communities on a combined basis in excess of the target capital investment. Unless otherwise agreed, the target capital investment increases annually based on the greater of the annual increase of CPI or 2%. Any senior living communities that are undergoing a major renovation or repositioning are excluded from the calculation of the incentive fee. The Master Management Agreement expires in 2036, subject to our right to extend for two consecutive five year terms if we achieve certain performance targets for the combined managed communities portfolio, unless earlier terminated. Pursuant to the Master Management Agreement, beginning in 2025, DHC will have the right to terminate up to 10% of the senior living communities, based on total revenues per year for failure to meet 80% of a target EBITDA for the applicable period. As part of the repositioning of our residential management business, we transitioned the management of 107 senior living communities that we managed for DHC with approximately 7,400 living units to new operators during the third and fourth quarters of 2021. We closed one senior living community with approximately 100 living units that we managed for DHC in February 2022. During the year ended December 31, 2021, we closed all 1,532 skilled nursing facility, or SNF, living units within the 27 CCRC communities, of which 1,473 living units were closed during the three months ended June 30, 2021. For the three and six months ended June 30, 2021, we recognized $4,378 and $9,619, respectively, of residential management fees related to the management of these senior living communities and living units. As of June 30, 2022 and 2021, we managed 120 and 228 senior living communities, respectively, for DHC. We earned residential management fees of $8,174 and $12,109 from the senior living communities we managed for DHC for the three months ended June 30, 2022 and 2021, respectively, and $16,216 and $25,019 for the six months ended June 30, 2022 and 2021, respectively.

These amounts are included in residential management fees in our condensed consolidated statements of operations. We also provide lifestyle services to residents at some of the senior living communities we manage for DHC, such as rehabilitation and wellness services. At senior living communities we manage for DHC where we provide rehabilitation and wellness services on an outpatient basis, the residents, third party payers or government programs pay us for those rehabilitation and wellness services. At senior living communities we previously managed for DHC where we currently provide or previously provided inpatient rehabilitation and wellness services, DHC generally pays us for these services and charges for such services are included in amounts charged to residents, third party payers or government programs. We earned revenues of $1,736 and $2,630 for the three months ended June 30, 2022 and 2021, respectively, and $3,652 and $8,071 for the six months ended June 30, 2022 and 2021, respectively, for lifestyle services we provided at senior living communities we previously managed for DHC and that were payable by DHC. These amounts are included in lifestyle services revenues in our condensed consolidated statements of operations.

See Note 1 to our Consolidated Financial Statements included in Part IV, Item 5 of our Annual Report for additional information about our management agreements with DHC. We previously leased four senior living communities from PEAK. On September 30, 2021, we and PEAK terminated our leases for all four communities that we leased from PEAK. These four communities had approximately 200 living units and had residential revenues of $1,554 and lease expense of $735 for the three months ended June 30, 2021 and $3,436 and $1,461 for the six months ended June 30, 2021, respectively.

As of the date of that renewal, the annual lease payments were scheduled to range from $1,026 to $1,395 over the term of the lease. On January 10, 2022, we and the ABP Trust subsidiary further amended the lease, which reduced the leased space from approximately 41,000 square feet to approximately 30,000 square feet.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We have been, are currently, and expect in the future to be involved in claims, lawsuits, and regulatory and other government audits, investigations and proceedings arising in the ordinary course of our business, some of which may involve material amounts. Also, the defense and resolution of these claims, lawsuits, and regulatory and other government audits, investigations and proceedings may require us to incur significant expense. Loss contingency provisions are recorded for probable and estimable losses at our best estimate of a loss or, when a best estimate cannot be made, at our estimate of the minimum loss. These estimates are often developed prior to knowing the amount of the ultimate loss, require the application of considerable judgment and are refined as additional information becomes known. Accordingly, we are often initially unable to develop a best estimate of loss and therefore the estimated minimum loss amount, which could be zero, is recorded; then, as information becomes known, the minimum loss amount is updated, as appropriate. In July 2021, we became aware of a potential issue with respect to completion of a form at one of the SNFs we previously managed for DHC. As a result of this discovery, we have made a voluntary self-disclosure to the Office of the Inspector General of HHS, or OIG, pursuant to the OIG's Provider Self-Disclosure Protocol. We submitted our initial disclosure to the OIG in January 2022, and are in discussions with the OIG regarding possible damages. Based on the costs that we have incurred or expect to incur, including estimated OIG imposed penalties, and factoring in DHC's related obligations, we have recorded a total of $288 to general and administrative expenses in our consolidated statements of operations in the fourth quarter of 2021 and second quarter of 2022. In connection with our arrangement with Compass Group, or the Compass Agreement, to manage resident dining at the senior living communities we own or manage, we are obligated to repay amounts totaling $1,433 and $1,232, respectively, for incentives and transition costs incurred by the Compass Group in relation to the twenty communities that had been transitioned as of June 30, 2022, of which $1,231 and $969, respectively, would be reimbursable by DHC, if we terminate the agreement prior to the end of 72 months, or January 1, 2028. The repayments amounts are also subject to interest. We expect the majority of the remaining senior living communities to transition dining services to Compass Group in the next twelve months.

Subsequent Events [Abstract]
Subsequent Event	Subsequent Event On July 2, 2022, we entered into an agreement to terminate the lease for our headquarters with a termination date of September 30, 2022. We also entered into a separate agreement to assume a lease from Sonesta for our headquarters as of September 1, 2022 at 255 Washington Street, Newton, Massachusetts. See Note 14 for further information on these lease agreements. On August 3, 2022, we announced a restructuring plan based on a comprehensive operational review that was completed by Alvarez & Marsal, or A&M. The recommendations made by A&M include general and administrative cost reductions, a corporate reorganization that is designed to enhance accountability and certain operational changes to support team members to ensure the delivery of high-quality experiences to residents and customers and to increase occupancy at the Company’s senior living communities. Pursuant to this restructuring plan, we intend to eliminate certain positions in our corporate team. We expect to complete this restructuring by the middle of 2023. In connection with implementing this restructuring plan, we expect to incur non-recurring cash expenses of up to $6,100. These expenses are expected to include up to $200 of retention payments, up to $2,600 of severance, benefits and transition expenses, and up to $3,300 of restructuring expenses.

Accounting Policies [Abstract]
Estimates and Assumptions	The preparation of these condensed consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that may affect the amounts reported in these condensed consolidated financial statements and related notes. Significant estimates in our condensed consolidated financial statements relate to revenue recognition, including contractual allowances and implicit price concessions, recoverability of long-lived assets, self-insurance reserves and estimates concerning our provision for income taxes or valuation allowance related to deferred tax assets.Our actual results could differ from our estimates. We periodically review estimates and assumptions, and we reflect the effects of changes, if any, in the condensed consolidated financial statements in the period that they are determined.
Recently Issued Accounting Pronouncements Not Yet Adopted	In June 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2016-13, Financial Instruments-Credit Losses (Topic 326) , which requires a financial asset or a group of financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. This ASU eliminates the probable initial recognition threshold and instead requires reflection of an entity’s current estimate of all expected credit losses. In addition, this ASU amends the current other-than-temporary impairment model for available for sale debt securities. The length of time that the fair value of an available for sale debt security has been below the amortized cost will no longer impact the determination of whether a credit loss exists and credit losses will now be limited to the difference between a security’s amortized cost basis and its fair value. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses , which amends the transition and effective date for nonpublic entities and smaller reporting companies, such as us, and clarifies that receivables arising from operating leases are not in the scope of this ASU. In November 2019, the FASB issued ASU No. 2019-11, Codification Improvements to Topic 326 , Financial Instruments-Credit Losses , which clarifies guidance around how to report expected recoveries. Entities will apply the provisions of the ASU as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. This ASU is effective for smaller reporting companies for reporting periods beginning after December 15, 2022. We are currently assessing the potential impact that the adoption of this ASU (and the related clarifying guidance issued by the FASB) will have on our condensed consolidated financial statements. In June 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820) - Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions , which clarifies that a contractual sale restriction prohibiting the sale of an equity security is a characteristic of the reporting entity holding the equity security and is not included in the equity security's unit of account. Accordingly, an entity should not consider the contractual sale restriction when measuring the equity security’s fair value. In addition, the ASU prohibits an entity from recognizing a contractual sale restriction as a separate unit of account. This ASU will be effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. We are currently assessing the potential impact that the adoption of this ASU will have on our condensed consolidated financial statements.

Cash equivalents are reported in our condensed consolidated balance sheets as cash and cash equivalents and current and long-term restricted cash and cash equivalents. Cash equivalents include $20,363 and $23,546 of balances that were restricted at June 30, 2022 and December 31, 2021, respectively. In addition to the cash equivalents of $37,564 and $26,417 at June 30, 2022 and December 31, 2021, respectively, reflected above, there were cash balances of $66,259 and $64,116 and restricted cash balances of $2,513 and $2,406 at June 30, 2022 and December 31, 2021, respectively. (2) The fair value of our equity investments is readily determinable. During the six months ended June 30, 2022 and 2021, we received gross proceeds of $521 and $741, respectively, in connection with the sales of equity investments and recorded gross realized gains totaling $0 and $175, respectively, and gross realized losses totaling $45 and $0, respectively. (3) As of June 30, 2022, our debt investments, which are classified as available for sale, had a fair value of $8,733 with an amortized cost of $9,223; the difference between the fair value and amortized cost amounts resulted from net unrealized losses of $490, inclusive of unrealized gains of $6. As of December 31, 2021, our debt investments had a fair value of $10,375 with an amortized cost of $10,079; the difference between the fair value and amortized cost amounts resulted from net unrealized gains of $296, inclusive of unrealized losses of $10. Debt investments include $7,081 and $6,907 of balances that were restricted as of June 30, 2022 and December 31, 2021, respectively. At June 30, 2022, 86 debt investments we held, with a fair value of $7,383, had been in a loss position for less than 12 months and one of the debt investments we held, with a fair value of $49, had been in a loss position for greater than 12 months. We do not believe these investments are impaired primarily because they have not been in a loss position for an extended period of time, the financial conditions of the issuers of these investments remain strong with solid fundamentals as of June 30, 2022, we do not intend to sell the investments and it is not more likely than not that we will be required to sell the investments before recovery, and other factors that support our conclusion that the loss is temporary. During the six months ended June 30, 2022 and 2021, we received gross proceeds of $705 and $1,294, respectively, in connection with the sales of debt investments and recorded gross realized losses of $(3) and $0, respectively, and gross realized gains of $1 and $18, respectively, during the six months ended June 30, 2022 and 2021. We record gains and losses on the sales of these investments using the specific identification method.
