Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies For more information regarding our significant accounting policies and estimates, please refer to “Summary of Significant Accounting Policies” contained in the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the Securities and Exchange Commission (“SEC”) on March 31, 2022. In addition, refer to our revenue recognition note below related to our resident fees and services. The accompanying condensed consolidated balance sheet at December 31, 2021 has been derived from the audited consolidated financial statements at that date. We assume that users of these condensed consolidated financial statements have read or have access to the audited December 31, 2021 consolidated financial statements and contained in our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 31, 2022 and that the adequacy of additional disclosure needed for a fair presentation, except in regard to material contingencies, may be determined in that context. Accordingly, footnotes and other disclosures which would substantially duplicate those contained in our most recent Annual Report on Form 10-K for the year ended December 31, 2021 have been omitted in this report. Principles of Consolidation and Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, the Operating Partnership and its consolidated companies and are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). All intercompany accounts and transactions have been eliminated in consolidation. The accompanying financial information reflects all adjustments, which are, in the opinion of management, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods. Interim results of operations are not necessarily indicative of the results to be expected for the full year. Operating results for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. Restricted Cash The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the condensed consolidated balance sheets that sum to the total of the same such amounts shown on the condensed consolidated statements of cash flows. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ 2022 2021 Cash and cash equivalents ​ $ 13,705,000 ​ $ 10,488,000 Restricted cash ​ 2,696,000 ​ 2,673,000 Total cash, cash equivalents, and restricted cash shown on the condensed consolidated statements of cash flows ​ $ 16,401,000 ​ $ 13,161,000 ​ Coronavirus (COVID-19) The world was, and continues to be, impacted by the COVID-19 pandemic. The healthcare industry was among those most adversely affected by the COVID-19 pandemic. During 2021 and 2020 and continuing into 2022, two of our tenants experienced a material adverse effect on their operations related to COVID-19, which affected their ability to make their rent payments in 2021 (see Note 3 for further information on its impact on us). The extent to which COVID-19 could continue to impact our business, cash flow and results of operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the rate of public acceptance and usage of vaccines and the effectiveness of vaccines in limiting the spread of COVID-19 and its variants, resurgences of COVID-19 and, in particular, new and more contagious and/or vaccine resistant variants, actions taken to contain the spread of COVID-19 and how quickly and to what extent normal economic and operating conditions can resume. The fluidity of this situation precludes any prediction as to the ultimate material adverse impact on the demand for senior housing and skilled nursing and presents material uncertainty and risk with respect to our business, operations, financial condition and liquidity, including recording impairments, lease modifications and credit losses in future periods. Reclassification of Intangible Lease Assets The following table provides a reconciliation for the reclassification of our intangible lease assets as of December 31, 2021 in our consolidated ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As previously reported Increase (decrease) As reclassified Real estate assets, net ​ $ 192,862,000 ​ $ (13,760,000) ​ $ 179,102,000 Intangible lease assets, net ​ $ — ​ $ 14,687,000 ​ $ 14,687,000 Other assets, net ​ $ 1,349,000 ​ $ (927,000) ​ $ 422,000 Total assets ​ $ 219,126,000 ​ $ — ​ $ 219,126,000 ​ The intangible lease assets related to our prior acquisitions in 2021 were reclassified from real estate properties, net and other assets, net into a separate line item as of March 31, 2022. The result of this reclassification did not have any effect on our total assets, liabilities, accumulated deficit, net loss or statements of cash flows. Revenue Recognition - Resident Fees and Services We recognize resident fees and services revenue at the amount that we expect to be entitled to in exchange for providing resident care and services. Resident fees are recognized and billed monthly based on the contracted rate in the resident lease agreements and the reimbursements from Medicaid are based on contracted reimbursement rates. These amounts are paid directly from the residents and/or third-party payors (currently only Medicaid). Revenue is recognized as performance obligations are satisfied. Performance obligations are determined based on the nature of the services provided by us. The majority of resident fees and services is attributable to the portion of the base monthly lease fee in the resident lease agreement. The Company has elected the lessor practical expedient within ASC 842, Leases (“ASC 842”) and recognizes the resident fee revenue based upon the predominant component, either the lease or non-lease component, of the contracts. The Company has determined that the lease component is the predominant component and the services included under the resident agreements have the same timing and pattern of transfer and are performance obligations that are satisfied over time. Resident services consist of care level services and certain other ancillary services (i.e., housekeeping, laundry, etc.). These services are provided and paid for in addition to the standard fees included in each resident lease (i.e., room and board, standard meals, etc.). Laws and regulations concerning government programs, including Medicare and Medicaid, are complex and subject to varying interpretation. As a result of investigations by governmental agencies, various healthcare organizations have received requests for information and notices regarding alleged noncompliance with those laws and regulations, which, in some instances, have resulted in organizations entering into significant settlement agreements. Compliance with such laws and regulations may also be subject to future government review and interpretation as well as significant regulatory action, including fines, penalties and potential exclusion from the related programs. There can be no assurance that regulatory authorities will not challenge our compliance with these laws and regulations, and it is not possible to determine the impact (if any) such claims or penalties would have upon us. Settlements with third-party payors for retroactive adjustments due to audits, reviews or investigations are considered variable consideration and are included in the determination of the estimated transaction price for providing patient care. These settlements are estimated based on the terms of the payment agreement with the payor, correspondence from the payor and our historical settlement activity, including an assessment to ensure that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustment is subsequently resolved. Estimated settlements are adjusted in future periods as adjustments become known (that is, new information becomes available), or as years are settled or are no longer subject to such audits, reviews and investigation.

Investments in Real Estate Properties As of March 31, 2022 and December 31, 2021, our investments in real estate properties including those held by our consolidated subsidiaries (excluding the 35 properties owned by our unconsolidated Equity-Method Investments) are set forth below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ 2022 2021 Land ​ $ 15,565,000 ​ $ 15,565,000 Buildings and improvements ​ 166,989,000 ​ 166,989,000 Less: accumulated depreciation ​ (12,546,000) ​ (11,395,000) Buildings and improvements, net ​ 154,443,000 ​ 155,594,000 Furniture and fixtures ​ 12,137,000 ​ 12,137,000 Less: accumulated depreciation ​ (4,626,000) ​ (4,194,000) Furniture and fixtures, net ​ 7,511,000 ​ 7,943,000 Real estate properties, net ​ $ 177,519,000 ​ $ 179,102,000 ​ For the three months ended March 31, 2022 and 2021, depreciation and amortization expense (excluding lease intangibles amortization and leasing commission amortization) was approximately $1.6 million and $0.4 million, respectively. As of March 31, 2022, our portfolio consisted of 18 real estate properties, 17 of which were 100% leased to the tenants of the related facilities. The remaining property is leased to an affiliated subsidiary (see below under Pennington Gardens Operations LLC). During 2021, our tenants for the Pennington Gardens and Sundial Assisted Living facilities experienced a material adverse effect on their operations related to COVID-19 and other operator issues that affected their ability to make their rent payments in 2022 and 2021. As a result, we experienced the following impacts: Pennington Gardens Operations LLC In March 2021, under a receivership, we began recording rent payments on a cash basis for our Pennington Gardens facility and wrote off the remaining straight-line rent receivable of $0.4 million. In October 2021, we reached an agreement with the tenant to terminate the lease. We notified the lender and the U.S. Department of Housing and Urban Development (“HUD”) and requested emergency approval to change the operator and terminate the lease. On February 3, 2022, the current receiver, who was acting as the operator, received the license to be the licensed operator. As such, on February 10, 2022, the tenant’s lease was terminated, and we received $0.2 million from the tenant as part of the settlement agreement which was recorded in total rental revenues in the condensed consolidated statements of operations for the three months ended March 31, 2022. Concurrently, we entered into a new lease agreement with Pennington Gardens Operations LLC, the newly formed operating company for Pennington Gardens, which is a wholly owned subsidiary of SHOP TRS LLC, a recently formed wholly-owned taxable REIT subsidiary of Summit. As such, the operations of Pennington Gardens are consolidated in our financial statements beginning February 11, 2022, and all intercompany transactions have been eliminated. For the three months ended March 31, 2022, revenues from Pennington Gardens Operations are recorded under resident fees and services and costs are recorded under resident costs in the condensed consolidated statements of operations. Sundial Operations LLC For our Sundial Assisted Living facility in Redding, California, in October 2021, we reached an agreement with the tenant to terminate the lease, and we are currently requesting approval from HUD to terminate the lease and install a new licensed operator/manager.

Concentration of Risk
Concentration of Risk	9. Concentration of Risk Our cash is generally invested in short-term money market instruments. As of March 31, 2022, we had cash and cash equivalent accounts in excess of FDIC-insured limits. However, we do not believe the risk associated with this excess is significant. As of March 31, 2022, we owned eight properties in Georgia, four properties in California, three properties in Oregon, one property in Texas, one property in Illinois, and one property in Arizona (excluding the 35 properties held by our Equity-Method Investments). Accordingly, there is a geographic concentration of risk subject to economic conditions in certain states. Additionally, for the three months ended March 31, 2022, we leased our 18 real estate properties to 16 different tenants under long-term triple net leases, and three of the 16 tenants each represented more than 10% of our rental revenue. For the three months ended March 31, 2021, we leased our seven real estate properties to five different tenants under long-term triple net leases, and four of the five tenants each represented more than 10% of our rental revenue. As of March 31, 2022, our GA8 Properties are considered to be a significant asset concentration as the aggregate net assets of the GA8 Properties were greater than 20% of our total assets due to cross-default provisions in the leases.

Fair Value Measurements of Financial Instruments
Fair Value Measurements of Financial Instruments	10. Fair Value Measurements of Financial Instruments Our condensed consolidated balance sheets include the following financial instruments: cash and cash equivalents, restricted cash, tenant and other receivables, certain other assets, accounts payable and accrued liabilities, security deposits and loans payable. With the exception of the loans payable discussed below, we consider the carrying values to approximate fair value for such financial instruments because of the short period of time between origination of the instruments and their expected payment. As of March 31, 2022 and December 31, 2021, the fair value of loans payable was $177.1 million and $177.3 million, compared to the principal balance (excluding debt discount) of $184.6 million and $184.9 million, respectively. The fair value of loans payable was estimated using lending rates available to us for financial instruments with similar terms and maturities. To estimate fair value as of March 31, 2022, we utilized discount rates ranging from 4.0% to 12.0% and a weighted average discount rate of 6.0%. As the inputs to our valuation estimate are neither observable in nor supported by market activity, our loans payable are classified as Level 3 liability within the fair value hierarchy. As a result of our ongoing analysis for potential impairment of our investments in real estate, we may be required to adjust the carrying value of certain assets to their estimated fair values, or estimated fair value less selling costs, under certain circumstances. No impairments were recorded during the three months ended March 31, 2022 and 2021. At March 31, 2022 and December 31, 2021, we do not have any financial assets or financial liabilities that are measured at fair value on a recurring basis in our condensed consolidated financial statements.

Commitments and Contingencies
Commitments and Contingencies	11. Commitments and Contingencies We inspect our properties under a Phase I assessment for the presence of hazardous or toxic substances. While there can be no assurance that a material environmental liability does not exist, we are not currently aware of any environmental liability with respect to the properties that would have a material effect on our consolidated financial condition, results of operations and cash flows. Further, we are not aware of any environmental liability or any unasserted claim or assessment with respect to an environmental liability that we believe would require additional disclosure or the recording of a loss contingency. Our commitments and contingencies include the usual obligations of real estate owners and licensed operators in the normal course of business. In the opinion of management, these matters are not expected to have a material impact on our consolidated financial condition, results of operations and cash flows. We are also subject to contingent losses resulting from litigation against the Company. Legal Proceedings In September 2015, a bankruptcy petition was filed against Healthcare Real Estate Partners, LLC (“HCRE”) by the investors in Healthcare Real Estate Fund, LLC and Healthcare Real Estate Qualified Purchasers Fund, LLC (collectively, the “Funds”). HCRE did not timely respond to the involuntary petition and the Bankruptcy Court entered an Order of Relief making HCRE a debtor in bankruptcy. As a result, HCRE was removed as manager under the Funds’ operating agreement. Thereafter the Company became the manager of the Funds and purchased the investors’ interests in the Funds for approximately $0.9 million. Following the subsequent dismissal of the involuntary bankruptcy petition filed against it, HCRE filed a motion for attorneys’ fees and damages and a separate complaint for violation of the automatic stay against the petitioning creditors and the Company in the United States Bankruptcy Court of the District of Delaware. The Bankruptcy Court granted a motion to dismiss the complaint for violation of the automatic stay filed jointly by the petitioning creditors and us, and dismissed the complaint with prejudice. HCRE appealed the Bankruptcy Court’s decision to the United States District Court for the District of Delaware which affirmed the Bankruptcy Court’s dismissal of the complaint in a decision dated September 9, 2018. On October 11, 2018, HCRE appealed the District Court’s decision affirming the Bankruptcy Court’s dismissal of the complaint to the United States Court of Appeals for the Third Circuit. On October 22, 2019, the Third Circuit granted HCRE’s appeal, reversing the District Court and holding that HCRE could assert the adversary complaint seeking damages for violation of the automatic stay. The Company filed a Petition for Rehearing on November 5, 2019 asserting that HCRE is not entitled to assert a claim for damages for violation of the automatic stay. This Petition was denied and the mandate was issued sending the matter back to the Bankruptcy Court. The Bankruptcy Court held a status conference on February 4, 2021, and subsequently entered scheduling orders to govern discovery and pretrial matters, and discovery is ongoing. The parties have filed dispositive motions, including a motion filed by the Company and the petitioning creditors for judgment on the pleadings. On February 4, 2022, the Bankruptcy Court entered an order denying the motion for judgment on the pleadings on the basis that the Bankruptcy Court would consider the points raised therein after trial. The Bankruptcy Court also entered an order denying HCRE’s motion to dismiss certain counterclaims and severing certain other counterclaims asserted by the petitioning creditors and the Company against HCRE on jurisdictional grounds, with the effect that such counterclaims may be pursued in the United States District Court. The Bankruptcy Court subsequently entered a further amended scheduling order, directing that remaining discovery be completed by May 15, 2022 and scheduling a final pretrial conference for August 17, 2022. Based on the assessment by management of the numerous legal arguments that can be raised on this claim, the Company believes that a loss is currently not probable or estimable under ASC 450, “Contingencies”, and as of December 31, 2021 no accrual has been made with regard to the claim. We will continue to vigorously defend ourselves against all of HCRE’s remaining alleged claims. Indemnification and Employment Agreements We have entered into indemnification agreements with certain of our executive officers and directors which indemnify them against all judgments, penalties, fines and amounts paid in settlement and all expenses actually and reasonably incurred by him or her in connection with any proceeding. Additionally, effective October 19, 2021, we entered into new employment agreements with our executive officers for a term of three years. These employment agreements include customary terms relating to salary, bonus, position, duties and benefits (including eligibility for equity compensation), as well as a cash payment following a change in control of the Company, as defined in such agreements. Management of our Equity-Method Investments As the manager of our Equity-Method Investments, we are responsible for the day-to-day management. Additionally, we could be subject to a capital call from our Equity-Method Investments.

Equity	3 Months Ended

Equity
Equity	12. Equity Share-Based Compensation Plans Upon the grant of stock options, we determine the exercise price by using our estimated per-share value, which is calculated by aggregating the estimated fair value of our investments in real estate and the estimated fair value of our other assets, subtracting the book value of our liabilities, utilizing a discount for the fact that the shares are not currently traded on a national securities exchange and a lack of a control premium, and divided by the total by the number of our common shares outstanding at the time the options were granted. The fair value of each grant is estimated on the date of grant using the Black-Scholes option-pricing model. Assumptions required by the model include the risk-free interest rate, the expected life of the options, the expected stock price volatility over the expected life of the options, and the expected distribution yield. Compensation expense for employee stock options is recognized ratably over the vesting term. The expected life of the options was based on the simplified method as we do not have sufficient historical exercise data. The risk-free interest rate was based on the U.S. Treasury yield curve at the date of grant with maturity dates approximating the expected term of the options at the date of grant. Volatility was based on historical volatility of the stock prices for a sample of publicly traded companies with risk profiles similar to ours. The valuation model applied in this calculation utilizes highly subjective assumptions that could potentially change over time, including the expected stock price volatility and the expected life of an option. The following table summarizes our stock options as of March 31, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ ​ ​ Weighted ​ Average ​ ​ ​ ​ ​ ​ ​ Average ​ Remaining ​ Aggregate ​ ​ ​ ​ Exercise ​ Contractual ​ Intrinsic ​ Options Price Term Value Options outstanding at January 1, 2022 1,867,908 ​ $ 2.09 ​ ​ ​ Granted — ​ ​ ​ ​ ​ Exercised — ​ ​ ​ ​ ​ Cancelled/forfeited — ​ ​ ​ ​ ​ Options outstanding at March 31, 2022 1,867,908 ​ $ 2.09 5.56 ​ $ 1,597,000 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Options exercisable at March 31, 2022 1,855,963 ​ $ 2.08 5.55 ​ $ 1,588,000 ​ For our outstanding non-vested options as of March 31, 2022, the weighted average grant date fair value per share was $0.57. As of March 31, 2022, we have unrecognized stock-based compensation expense related to unvested stock options which is expected to be recognized as follows: ​ ​ ​ ​ ​ Years Ending December 31, ​ ​ April 1, 2022 to December 31, 2022 ​ $ 6,000 2023 ​ 1,000 ​ ​ $ 7,000 ​ The stock-based compensation expense reported for the three months ended March 31, 2022 and 2021 was approximately $8,000 and $36,000, respectively, and is included in general and administrative expense in the condensed consolidated statements of operations.

Subsequent Events	13. Subsequent Events Office lease On April 1, 2022, we entered into a temporary space license agreement (“Temporary License”) and a standard office lease (“New Lease”) with Lakehills CM-CG LLC. ​ The Temporary License, for space located in Laguna Hills, California, begins on April 22, 2022 and expires on the date we move out of such temporary office space or five (5) days after the substantial completion of certain tenant improvements in the office space subject to the New Lease, but in no event later than March 31, 2023. We are entitled to use such office space at no cost during the term of the Temporary License. ​ Concurrent with the execution of the Temporary License, we entered into the New Lease which begins on or about November 1, 2022 for a period of sixty-six (66) months, with a five-year renewal option. The office space subject to the New Lease is also located in Laguna Hills, California. The New Lease provides for the abatement of the base rent for the second full calendar month through the seventh full calendar month of the lease term. The initial annual base rent is $204,399 and increases three percent (3%) each year on the anniversary date of the commencement of the New Lease. Stock Options On April 1, 2022, we granted 81,000 stock options to our non-executive employees under our Summit Healthcare REIT, Inc. 2015 Omnibus Incentive Plan (“Incentive Plan”). The stock options vest monthly beginning on May 1, 2022 and continuing over a three-year period through April 1, 2025. The options expire 10 years from the grant date.

All intercompany accounts and transactions have been eliminated in consolidation. The accompanying financial information reflects all adjustments, which are, in the opinion of management, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods. Interim results of operations are not necessarily indicative of the results to be expected for the full year. Operating results for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022.

Coronavirus (COVID-19)	Coronavirus (COVID-19) The world was, and continues to be, impacted by the COVID-19 pandemic. The healthcare industry was among those most adversely affected by the COVID-19 pandemic. During 2021 and 2020 and continuing into 2022, two of our tenants experienced a material adverse effect on their operations related to COVID-19, which affected their ability to make their rent payments in 2021 (see Note 3 for further information on its impact on us). The extent to which COVID-19 could continue to impact our business, cash flow and results of operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the rate of public acceptance and usage of vaccines and the effectiveness of vaccines in limiting the spread of COVID-19 and its variants, resurgences of COVID-19 and, in particular, new and more contagious and/or vaccine resistant variants, actions taken to contain the spread of COVID-19 and how quickly and to what extent normal economic and operating conditions can resume. The fluidity of this situation precludes any prediction as to the ultimate material adverse impact on the demand for senior housing and skilled nursing and presents material uncertainty and risk with respect to our business, operations, financial condition and liquidity, including recording impairments, lease modifications and credit losses in future periods.
Reclassification of Intangible Lease Assets	Reclassification of Intangible Lease Assets The following table provides a reconciliation for the reclassification of our intangible lease assets as of December 31, 2021 in our consolidated ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As previously reported Increase (decrease) As reclassified Real estate assets, net ​ $ 192,862,000 ​ $ (13,760,000) ​ $ 179,102,000 Intangible lease assets, net ​ $ — ​ $ 14,687,000 ​ $ 14,687,000 Other assets, net ​ $ 1,349,000 ​ $ (927,000) ​ $ 422,000 Total assets ​ $ 219,126,000 ​ $ — ​ $ 219,126,000 ​ The intangible lease assets related to our prior acquisitions in 2021 were reclassified from real estate properties, net and other assets, net into a separate line item as of March 31, 2022. The result of this reclassification did not have any effect on our total assets, liabilities, accumulated deficit, net loss or statements of cash flows.
Revenue Recognition - Resident Fees and Services	Revenue Recognition - Resident Fees and Services We recognize resident fees and services revenue at the amount that we expect to be entitled to in exchange for providing resident care and services. Resident fees are recognized and billed monthly based on the contracted rate in the resident lease agreements and the reimbursements from Medicaid are based on contracted reimbursement rates. These amounts are paid directly from the residents and/or third-party payors (currently only Medicaid). Revenue is recognized as performance obligations are satisfied. Performance obligations are determined based on the nature of the services provided by us. The majority of resident fees and services is attributable to the portion of the base monthly lease fee in the resident lease agreement. The Company has elected the lessor practical expedient within ASC 842, Leases (“ASC 842”) and recognizes the resident fee revenue based upon the predominant component, either the lease or non-lease component, of the contracts. The Company has determined that the lease component is the predominant component and the services included under the resident agreements have the same timing and pattern of transfer and are performance obligations that are satisfied over time. Resident services consist of care level services and certain other ancillary services (i.e., housekeeping, laundry, etc.). These services are provided and paid for in addition to the standard fees included in each resident lease (i.e., room and board, standard meals, etc.). Laws and regulations concerning government programs, including Medicare and Medicaid, are complex and subject to varying interpretation. As a result of investigations by governmental agencies, various healthcare organizations have received requests for information and notices regarding alleged noncompliance with those laws and regulations, which, in some instances, have resulted in organizations entering into significant settlement agreements. Compliance with such laws and regulations may also be subject to future government review and interpretation as well as significant regulatory action, including fines, penalties and potential exclusion from the related programs. There can be no assurance that regulatory authorities will not challenge our compliance with these laws and regulations, and it is not possible to determine the impact (if any) such claims or penalties would have upon us. Settlements with third-party payors for retroactive adjustments due to audits, reviews or investigations are considered variable consideration and are included in the determination of the estimated transaction price for providing patient care. These settlements are estimated based on the terms of the payment agreement with the payor, correspondence from the payor and our historical settlement activity, including an assessment to ensure that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustment is subsequently resolved. Estimated settlements are adjusted in future periods as adjustments become known (that is, new information becomes available), or as years are settled or are no longer subject to such audits, reviews and investigation.
