The Company's derivative assets include interest rate caps that effectively manage the risk above certain interest rates for a portion of the Company's variable rate debt. The derivative positions are valued using models developed internally by the respective counterparty that use as their basis readily available observable market parameters (such as forward yield curves) and are classified within Level 2 of the valuation hierarchy. The Company considers the credit risk of its counterparties when evaluating the fair value of its derivatives. The following table summarizes the Company's interest rate cap instruments as of December 31, 2020:

The Company estimates the fair value of its debt using a discounted cash flow analysis based upon the Company's current borrowing rate for debt with similar maturities and collateral securing the indebtedness. The Company had outstanding long-term debt with a carrying amount of approximately $3.9 billion and $3.6 billion as of December 31, 2020 and 2019, respectively. Fair value of the long-term debt approximates carrying amount in all periods presented. The Company's fair value of long-term debt disclosure is classified within Level 2 of the valuation hierarchy.

On July 26, 2020, the Company issued to Ventas a warrant to purchase up to 16.3 million shares of the Company’s common stock, at a price per share of $3.00. The fair value of this warrant of $22.9 million as of July 26, 2020 was estimated using the Black-Scholes option-pricing model utilizing a stock price volatility assumption of 65% which is considered a Level 2 input of the valuation hierarchy.

Although the Company cannot predict with reasonable certainty the ultimate impacts of the COVID-19 pandemic, the Company concluded that the impacts of the pandemic have adversely affected the Company’s projections of revenue, expense, and cash flow for its senior housing community long-lived assets and constitute an indicator of potential impairment. Accordingly, the Company assessed its long-lived assets for recoverability. Refer to Note 3 for additional information on the COVID-19 pandemic.

In estimating the recoverability of asset groups for purposes of the Company’s long-lived asset impairment testing during the year ended December 31, 2020, the Company utilized future cash flow projections that are developed internally. Any estimates of future cash flow projections necessarily involve predicting unknown future circumstances and events and require significant management judgments and estimates. In arriving at the cash flow projections, the Company considers its estimates of the impacts of the pandemic, historic operating results, approved budgets and business plans, future demographic factors, expected growth rates, estimated asset holding periods, and other factors.

As of December 31, 2020 there was a wide range of possible outcomes as a result of the pandemic, as there was a high degree of uncertainty about its ultimate impact. Management’s estimates of the impact of the pandemic are highly dependent on variables that are difficult to predict, as further described in Note 3. Future events may indicate differences from management's current judgments and estimates which could, in turn, result in future impairments.

During the three months ended March 31, 2018, the Company identified qualitative indicators of impairment of goodwill, including a significant decline in the Company's stock price and market capitalization for a sustained period during the three months ended March 31, 2018. As a result, the Company performed an interim quantitative goodwill impairment test as of March 31, 2018, which included a comparison of the estimated fair value of each reporting unit to which the goodwill has been assigned with the reporting unit's carrying amount.

In estimating the fair value of the reporting units for purposes of the quantitative goodwill impairment test, the Company utilized an income approach, which included future cash flow projections that are developed internally. Any estimates of future cash flow projections necessarily involve predicting unknown future circumstances and events and require significant management judgments and estimates. In arriving at the cash flow projections, the Company considered its historic operating results, approved budgets and business plans, future demographic factors, expected growth rates, and other factors. In using the income approach to estimate the fair value of reporting units for purposes of its goodwill impairment test, the Company made certain key assumptions. Those assumptions include future revenues, facility operating expenses, and cash flows, including sales proceeds that the Company would receive upon a sale of the communities using estimated capitalization rates, all of which are considered Level 3 inputs in the valuation hierarchy. The Company corroborated the estimated capitalization rates used in these calculations with capitalization rates observable from recent market transactions. Future cash flows are discounted at a rate that is consistent with a weighted average cost of capital from a market participant perspective. The weighted average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt holders of a business enterprise. The Company also considered market based measures such as earnings multiples in its analysis of estimated fair values of its reporting units.

During 2020, the Company identified indicators of impairment of goodwill, including the COVID-19 pandemic and a significant decline in the Company's stock price and market capitalization for a sustained period. Refer to Note 3 for additional information on the COVID-19 pandemic. As a result, the Company performed an interim quantitative goodwill impairment test as of March 31, 2020. The Company’s quantitative goodwill impairment test as of March 31, 2020 included reduced estimates of projected future cash flows as a result of changes to significant assumptions using information known or knowable about the COVID-19 pandemic, including current industry and economic trends, changes in business plans, and changes in expected revenue and facility operating expense growth rates. Additionally, the Company considered the additional risk within the future cash flow estimates when selecting risk-adjusted discount rates. As of December 31, 2020, the Company also considered that the estimated Health Care Services reporting unit fair value, based upon the transaction price for the Health Care Services segment as described in Note 21, exceeds its carrying amount.

The Company concluded that the remaining goodwill for all reporting units was not impaired as of October 1, 2020 and 2019 (the Company's annual measurement date) and as of December 31, 2020 and 2019. Goodwill allocated to the Company's Independent Living and Health Care Services reporting units is approximately $27.3 million and $126.8 million, respectively, as of December 31, 2020 and 2019.

Determining the fair value of the Company's reporting units involves the use of significant estimates and assumptions that are unpredictable and inherently uncertain. These estimates and assumptions include revenue and expense growth rates and operating margins used to calculate projected future cash flows and risk-adjusted discount rates. Future events may indicate differences from management's current judgments and estimates which could, in turn, result in future impairments. Future events that may result in impairment charges include differences in the projected occupancy rates or monthly service fee rates, changes in the cost structure of existing communities, changes in reimbursement rates from Medicare for healthcare services, and changes in healthcare reform. Significant adverse changes in the Company's future revenues and/or operating margins, significant changes in the market for healthcare services, senior housing or the valuation of the real estate of senior living communities, as well as other events and circumstances, including, but not limited to, increased competition, changes in reimbursement rates from Medicare for healthcare services, and changing economic or market conditions, including market control premiums, could result in changes in fair value and the determination that additional goodwill is impaired.

During the years ended December 31, 2020, 2019, and 2018, the Company evaluated property, plant and equipment and leasehold intangibles for impairment and identified properties with a carrying amount of the assets in excess of the estimated future undiscounted net cash flows expected to be generated by the assets. The Company compared the estimated fair value of the assets to their carrying amount for these identified properties and recorded an impairment charge for the excess of carrying amount over fair value. The Company recorded property, plant and equipment and leasehold intangibles non-cash impairment charges in its operating results of $29.3 million, $27.2 million, and $78.0 million for the years ended December 31, 2020, 2019, and 2018, respectively. The fair values of the assets of these communities were primarily determined utilizing a discounted cash flow approach or direct capitalization method considering stabilized facility operating income and market capitalization rates. These fair value measurements are considered Level 3 measurements within the valuation hierarchy. The range of capitalization rates utilized was 6.5% to 9.0%, depending upon the property type, geographical location, and the quality of the respective community. The Company corroborated the estimated fair values with a sales comparison approach with information observable from recent market transactions. These impairment charges are primarily due to the COVID-19 pandemic, lower than expected operating performance at these properties, or the Company's decision to dispose of assets and reflect the amount by which the carrying amounts of the assets exceeded their estimated fair value.

During the years ended December 31, 2020 and 2019, the Company evaluated operating lease right-of-use assets for impairment and identified communities with a carrying amount of the assets in excess of the estimated future undiscounted net cash flows expected to be generated by the assets. The Company compared the estimated fair value of the assets to their carrying amount for these identified communities and recorded an impairment charge for the excess of carrying amount over fair value. The Company recognized the right-of-use assets for the operating leases for 35 communities on the consolidated balance sheet as of March 31, 2020 at the estimated fair value of $106.7 million. During the three months ended June 30, 2020, the Company recognized the right-of-use assets for the operating leases for nine communities on the consolidated balance sheet at the estimated fair value of $10.3 million. During the three months ended September 30, 2020, the Company recognized the right-of-use assets for the operating leases for two communities on the consolidated balance sheets as of September 30, 2020 at

the estimated fair value of $3.0 million. During the three months ended December 31, 2020, the Company recognized the right-of-use assets for the operating leases for five communities on the consolidated balance sheet at the estimated fair value of $2.3 million. In the aggregate, the Company recorded a non-cash impairment charge of $76.3 million and $10.2 million for the years ended December 31, 2020 and 2019, respectively, to operating lease right-of-use assets. These 2020 impairment charges are primarily due to the COVID-19 pandemic and the lower than expected operating performance at these communities and reflect the amount by which the carrying amounts of the assets exceeded their estimated fair value.

The Company's adoption of ASU 2016-02 resulted in the recognition of the right-of-use assets for the operating leases for 25 communities to be recognized on the consolidated balance sheet as of January 1, 2019 at the estimated fair value of $56.6 million, and $58.1 million of previously unrecognized right-of-use asset impairments were recognized as a cumulative effect adjustment to accumulated deficit as the Company determined that the long-lived assets of such communities were not recoverable as of such date. See Note 2 for more information regarding the recognition of right-of-use assets for operating leases upon the adoption of ASU 2016-02.

The fair values of the operating lease right-of-use assets were estimated utilizing a discounted cash flow approach based upon projected community cash flows and market data, including management fees and a market supported lease coverage ratio, all of which are considered Level 3 inputs within the valuation hierarchy. The estimated future cash flows were discounted at a rate that is consistent with a weighted average cost of capital from a market participant perspective. The range of discount rates utilized was 9.0% to 12.3%, depending upon the property type, geographical location, and the quality of the respective community.

The Company evaluates realization of its investment in ventures accounted for using the equity method if circumstances indicate that the Company's investment is other than temporarily impaired. During the years ended December 31, 2020 and 2018 the Company recorded $1.5 million and $33.4 million, respectively, of non-cash impairment charges for investments in unconsolidated ventures. These impairment charges are primarily due to lower than expected operating performance at the communities owned by the unconsolidated ventures and reflect the amount by which the carrying amounts of the investments exceeded their estimated fair value. During the year ended December 31, 2019, the Company did not record impairment expense for its investment in unconsolidated ventures.

During the years ended December 31, 2020, 2019, and 2018, the Company recognized $0.2 million, $1.3 million, and $15.6 million, respectively, of impairment charges for assets held for sale. These impairment charges are primarily due to the excess of carrying amount over the estimated selling price less costs to dispose. The Company determines the fair value of the communities based primarily on purchase and sale agreements from prospective purchasers (Level 2 input). Refer to Note 4 for more information about the Company's community dispositions and assets held for sale.

During the years ended December 31, 2019 and 2018, the Company identified indicators of impairment for the Company's home health care licenses, primarily due to significant underperformance relative to historical and projected operating results, the impact of lower reimbursement rates from Medicare for home health care services, and an increased competitive environment in the home health care industry. The Company performed a quantitative impairment test, which included a comparison of the estimated fair value of the Company's home health care licenses to the carrying amount. In estimating the fair value of the home health licenses for purposes of the quantitative impairment test, the Company utilized an income approach, which included future cash flow projections that are developed internally. Any estimates of future cash flow projections necessarily involve predicting unknown future circumstances and events and require significant management judgments and estimates. In arriving at the cash flow projections, the Company considered its historic operating results, approved budgets and business plans, future demographic factors, expected growth rates, and other factors, all of which are considered Level 3 inputs in the valuation hierarchy. Based on the results of the Company's quantitative impairment test, the Company determined that the carrying amount of certain of the Company's home health care licenses exceeded their estimated fair value. As a result, the Company recorded a non-cash impairment charge of $7.6 million and $9.1 million for the years ended December 31, 2019 and 2018, respectively, to intangible assets within the Health Care Services segment.
