We also had partial ownership interests in 6 unconsolidated outlet centers totaling approximately 2.1 million square feet, including 2 outlet centers in Canada. Our outlet centers and other assets are held by, and all of our operations are conducted by, Tanger Properties Limited Partnership and subsidiaries. Accordingly, the descriptions of our business, employees and properties are also descriptions of the business, employees and properties of the Operating Partnership. Unless the context indicates otherwise, the term “Company” refers to Tanger Factory Outlet Centers, Inc. and subsidiaries and the term “Operating Partnership” refers to Tanger Properties Limited Partnership and subsidiaries.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The unaudited consolidated financial statements included herein have been prepared pursuant to accounting principles generally accepted in the United States of America and should be read in conjunction with the consolidated financial statements and notes thereto of the Company’s and the Operating Partnership’s combined Annual Report on Form 10-K for the year ended December 31, 2021. The December 31, 2021 balance sheet data in this Form 10-Q was derived from audited financial statements. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the SEC’s rules and regulations, although management believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the financial statements for the interim periods have been made. The results of interim periods are not necessarily indicative of the results for a full year. The Company currently consolidates the Operating Partnership because it has (1) the power to direct the activities of the Operating Partnership that most significantly impact the Operating Partnership’s economic performance and (2) the obligation to absorb losses and the right to receive the residual returns of the Operating Partnership that could be potentially significant. We consolidate properties that are wholly-owned and properties where we own less than 100% but control such properties. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities (“VIE”). For joint ventures that are determined to be a VIE, we consolidate the entity where we are deemed to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance, and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. Our determination of the primary beneficiary considers all relationships between us and the VIE, including management agreements and other contractual arrangements. Investments in real estate joint ventures that we do not control but may exercise significant influence on are accounted for using the equity method of accounting. These investments are recorded initially at cost and subsequently adjusted for our equity in the joint venture’s net income or loss, cash contributions, distributions and other adjustments required under the equity method of accounting. For certain investments in real estate joint ventures, we record our equity in the venture’s net income or loss under the hypothetical liquidation at book value method of accounting due to the structures and the preferences we receive on the distributions from our joint ventures pursuant to the respective joint venture agreements for those joint ventures. Under this method, we recognize income and loss in each period based on the change in liquidation proceeds we would receive from a hypothetical liquidation of our investment based on depreciated book value. Therefore, income or loss may be allocated disproportionately as compared to the ownership percentages due to specified preferred return rate thresholds and may be more or less than actual cash distributions received and more or less than what we may receive in the event of an actual liquidation. We separately report investments in joint ventures for which accumulated distributions have exceeded investments in, and our share of net income or loss of, the joint ventures within other liabilities in the consolidated balance sheets because we are committed to provide further financial support to these joint ventures. The carrying amount of our investments in the Charlotte, Columbus, Galveston/Houston, and National Harbor joint ventures are less than zero because of financing or operating distributions that were greater than net income, as net income includes non-cash charges for depreciation and amortization. “Noncontrolling interests in the Operating Partnership” reflects the Non-Company LP’s percentage ownership of the Operating Partnership’s units. “Noncontrolling interests in other consolidated partnerships” consist of outside equity interests in partnerships or joint ventures not wholly-owned by the Company or the Operating Partnership that are consolidated with the financial results of the Company and Operating Partnership because the Operating Partnership exercises control over the entities that own the properties. Noncontrolling interests are initially recorded in the consolidated balance sheets at fair value based upon purchase price allocations. Income is allocated to the noncontrolling interests based on the allocation provisions within the partnership or joint venture agreements. Accounts Receivable Individual leases are assessed for collectability and upon the determination that the collection of rents is not probable, accrued rent and accounts receivable are written-off as an adjustment to rental revenue. Revenue from leases where collection is deemed to be less than probable is recorded on a cash basis until collectability is determined to be probable. Further we assess whether operating lease receivables, at a portfolio level, are appropriately valued based upon an analysis of balances outstanding, historical bad debt levels and current economic trends including discussions with tenants for potential lease amendments. Our estimate of the collectability of accrued rents and accounts receivable is based on the best information available to us at the time of preparing the financial statements. Straight-line rent adjustments recorded as a receivable in prepaids and other assets on the consolidated balance sheets was approximately $51.6 million as of March 31, 2022. Impairment of Long-Lived Assets Rental property held and used by us is reviewed for impairment in the event that facts and circumstances indicate that the carrying amount of an asset may not be recoverable. In such an event, we compare the estimated future undiscounted cash flows associated with the asset to the asset's carrying amount, and if less, recognize an impairment loss in an amount by which the carrying amount exceeds its fair value.

Investments In Unconsolidated Real Estate Joint Ventures [Abstract]
Investments in Unconsolidated Real Estate Joint Ventures	Investments in Unconsolidated Real Estate Joint Ventures The equity method of accounting is used to account for each of the individual joint ventures. We have an ownership interest in the following unconsolidated real estate joint ventures: As of March 31, 2022 Joint Venture Outlet Center Location Ownership % Square Feet Carrying Value of Investment (in millions) Total Joint Venture Debt, Net (in millions) (1) Investments included in investments in unconsolidated joint ventures: RioCan Canada Various 50.0 % 665 83.0 — $ 83.0 Investments included in other liabilities: Columbus (2) Columbus, OH 50.0 % 355 $ (0.9) $ 70.9 Charlotte (2) Charlotte, NC 50.0 % 399 $ (17.3) $ 99.6 National Harbor (2) National Harbor, MD 50.0 % 341 (11.7) 94.6 Galveston/Houston (2) Texas City, TX 50.0 % 353 (13.9) 64.4 $ (43.8) As of December 31, 2021 Joint Venture Outlet Center Location Ownership % Square Feet Carrying Value of Investment (in millions) Total Joint Venture Debt, Net (in millions) (1) Investments included in investments in unconsolidated joint ventures: Columbus Columbus, OH 50.0 % 355 $ 0.2 $ 70.9 RioCan Canada Various 50.0 % 665 82.4 — $ 82.6 Investments included in other liabilities: Charlotte (2) Charlotte, NC 50.0 % 399 $ (16.2) $ 99.6 National Harbor (2) National Harbor, MD 50.0 % 341 (11.2) 94.5 Galveston/Houston (2) Texas City, TX 50.0 % 353 (14.0) 64.4 $ (41.4) (1) Net of debt origination costs of $1.0 million as of March 31, 2022 and $1.0 million as of December 31, 2021. (2) The negative carrying value is due to distributions exceeding contributions and increases or decreases from our equity in earnings of the joint venture. Fees we received for various services provided to our unconsolidated joint ventures were recognized in management, leasing and other services as follows (in thousands): Three months ended March 31, 2022 2021 Fee: Management and marketing $ 536 $ 509 Leasing and other fees 35 56 Expense reimbursements from unconsolidated joint ventures 956 807 Total Fees $ 1,527 $ 1,372 Our investments in real estate joint ventures are reduced by the percentage of the profits earned for leasing and development services associated with our ownership interest in each joint venture. Our carrying value of investments in unconsolidated joint ventures differs from our share of the assets reported in the “Condensed Combined Balance Sheets - Unconsolidated Joint Ventures” shown below due to adjustments to the book basis, including intercompany profits on sales of services that are capitalized by the unconsolidated joint ventures. The differences in basis (totaling $3.3 million and $3.4 million as of March 31, 2022 and December 31, 2021, respectively) are amortized over the various useful lives of the related assets. RioCan Canada In March 2021, the RioCan joint venture closed on the sale of its outlet center in Saint-Sauveur, for net proceeds of approximately $9.4 million. Our share of the proceeds was approximately $4.7 million. As a result of this transaction, we recorded a loss on the sale of $3.7 million. This includes a $3.6 million charge related to the foreign currency effect of the sale recorded in other income (expense), which had been previously recorded in other comprehensive income.

The unsecured lines of credit and senior unsecured notes include covenants that require the maintenance of certain ratios, including debt service coverage and leverage, and limit the payment of dividends such that dividends and distributions will not exceed funds from operations, as defined in the agreements, for the prior fiscal year on an annual basis or 95% of funds from operations on a cumulative basis. As of March 31, 2022, we believe we were in compliance with all of our debt covenants. Debt Maturities Maturities of the existing long-term debt as of March 31, 2022 for the next five years and thereafter are as follows (in thousands): Calendar Year Amount For the remainder of 2022 $ 3,360 2023 44,916 2024 305,130 2025 1,501 2026 355,705 Thereafter 700,000 Subtotal 1,410,612 Net discount and debt origination costs (14,075) Total $ 1,396,537 We have considered our short-term (one year or less from the date of filing these financial statements) liquidity needs and the adequacy of our estimated cash flows from operating activities and other financing sources to meet these needs. These other sources include but are not limited to: existing cash, ongoing relationships with certain financial institutions, our ability to sell debt or issue equity subject to market conditions and proceeds from the potential sale of non-core assets. We believe that we have access to the necessary financing to fund our short-term liquidity needs.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers are defined as follows: Tier Description Level 1 Observable inputs such as quoted prices in active markets Level 2 Inputs other than quoted prices in active markets that are either directly or indirectly observable Level 3 Unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions Fair Value Measurements on a Recurring Basis The following table sets forth our assets and liabilities that are measured at fair value within the fair value hierarchy (in thousands): Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Observable Inputs Significant Unobservable Inputs Total Fair value as of March 31, 2022: Assets: Short-term government securities ( cash and cash equivalents) $ 149,997 $ 149,997 $ — $ — Interest rate swaps (prepaids and other assets) 9,700 — 9,700 — Total assets $ 159,697 $ 149,997 $ 9,700 $ — Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Observable Inputs Significant Unobservable Inputs Total Fair value as of December 31, 2021: Asset: Short-term government securities ( cash and cash equivalents) $ 158,197 $ 158,197 $ — $ — Interest rate swaps (prepaids and other assets) $ 2,485 $ — $ 2,485 $ — Total assets $ 160,682 $ 158,197 $ 2,485 $ — Liabilities: Interest rate swaps (other liabilities) $ 459 $ — $ 459 $ — Total liabilities $ 459 $ — $ 459 $ — Short-term government securities Short-term government securities are highly liquid investments, which are classified as Level 1 in the fair value hierarchy because they are valued using quoted market prices in an active market. Interest rate swaps Fair values of interest rate swaps are estimated using Level 2 inputs based on current market data received from financial sources that trade such instruments and are based on prevailing market data and derived from third party proprietary models based on well recognized financial principles including counterparty risks, credit spreads and interest rate projections, as well as reasonable estimates about relevant future market conditions. Other Fair Value Disclosures The estimated fair value within the fair value hierarchy and recorded value of our debt consisting of senior unsecured notes, unsecured term loans, secured mortgages and unsecured lines of credit were as follows (in thousands): March 31, 2022 December 31, 2021 Level 1 Quoted Prices in Active Markets for Identical Assets or Liabilities $ — $ — Level 2 Significant Observable Inputs 990,555 1,079,234 Level 3 Significant Unobservable Inputs 362,563 366,103 Total fair value of debt $ 1,353,118 $ 1,445,337 Recorded value of debt $ 1,396,537 $ 1,397,076 Our senior unsecured notes are publicly-traded which provides quoted market rates. However, due to the limited trading volume of these notes, we have classified these instruments as Level 2 in the hierarchy. Our other debt is classified as Level 3 given the unobservable inputs utilized in the valuation. Our unsecured term loan, unsecured lines of credit and variable interest rate mortgages are all LIBOR based instruments. When selecting the discount rates for purposes of estimating the fair value of these instruments, we evaluated the original credit spreads and do not believe that the use of them differs materially from current credit spreads for similar instruments and therefore the recorded values of these debt instruments is considered their fair value. The carrying values of cash and cash equivalents, receivables, accounts payable, accrued expenses and other assets and liabilities are reasonable estimates of their fair values because of the short maturities of these instruments.

Shareholders' Equity of the Company	Shareholders’ Equity of the Company Dividend Declaration In January 2022, the Company's Board of Directors declared a $0.1825 cash dividend per common share payable on February 15, 2022 to each shareholder of record on January 31, 2022, and in its capacity as General Partner of the Operating Partnership, a $0.1825 cash distribution per Operating Partnership unit to the Operating Partnership's unitholders. At-the-Market Offering Under our at-the-market share offering program (“ATM Offering”), which commenced February 2021, we may offer and sell our common shares, $0.01 par value per share (“Common Shares”), having an aggregate gross sales price of up to $250.0 million (the “Shares”). We may sell the Shares in amounts and at times to be determined by us but we have no obligation to sell any of the Shares. Actual sales, if any, will depend on a variety of factors to be determined by us from time to time, including, among other things, market conditions, the trading price of the Common Shares, capital needs and determinations by us of the appropriate sources of funding. We currently intend to use the net proceeds from the sale of shares pursuant to the ATM Offering for working capital and general corporate purposes. As of March 31, 2022, we had approximately $60.1 million remaining available for sale under the ATM Offering program. The following table sets forth information regarding settlements under our ATM offering program: Three months ended March 31, 2022 2021 Number of common shares settled during the period — 6,867,078 Average price per share $ — $ 19.02 Aggregate gross proceeds (in thousands) $ — $ 130,638 Aggregate net proceeds after commissions and fees (in thousands) $ — $ 128,655 Share Repurchase Program In May 2021, the Company’s Board of Directors authorized the repurchase of up to $80.0 million of the Company’s outstanding shares through May 31, 2023. This authorization replaced a previous repurchase authorization for approximately $80.0 million that expired in May 2021. In June 2020, we amended our debt agreements primarily to improve future covenant flexibility and such amendments included a prohibition on share repurchases for twelve months starting July 1, 2020 (the “Repurchase Covenant”). The Company temporarily suspended share repurchases for the twelve months starting July 1, 2020 and ending on June 30, 2021 in light of a repurchase covenant. On July 1, 2021, the Repurchase Covenant expired.

Partners' Equity of the Operating Partnership	Partners’ Equity of the Operating Partnership All units of partnership interest issued by the Operating Partnership have equal rights with respect to earnings, dividends and net assets. When the Company issues common shares upon the exercise of options, the grant of restricted common share awards, or the exchange of Class A common limited partnership units, the Operating Partnership issues a corresponding Class B common limited partnership unit to Tanger LP Trust, a wholly-owned subsidiary of the Company. Likewise, when the Company repurchases its outstanding common shares, the Operating Partnership repurchases a corresponding Class B common limited partnership unit held by Tanger LP Trust. The following table sets forth the changes in outstanding partnership units for the three months ended March 31, 2022 and March 31, 2021: Limited Partnership Units General Partnership Units Class A Class B Total Balance December 31, 2020 1,000,000 4,794,643 92,569,801 97,364,444 Grant of restricted common share awards by the Company, net of forfeitures — — 469,675 469,675 Issuance of deferred units 100,000 — 6,767,078 6,767,078 Units withheld for employee income taxes — — (111,977) (111,977) Balance March 31, 2021 1,100,000 4,794,643 99,694,577 104,489,220 Balance December 31, 2021 1,100,000 4,761,559 102,984,734 107,746,293 Grant of restricted common share awards by the Company, net of forfeitures — — 512,398 512,398 Issuance of units — — — — Options exercised — — 1,900 1,900 Units withheld for employee income taxes — — (129,971) (129,971) Balance March 31, 2022 1,100,000 4,761,559 103,369,061 108,130,620

Earnings Per Share of the Company	Earnings Per Share of the Company The following table sets forth a reconciliation of the numerators and denominators in computing the Company’s earnings per share (in thousands, except per share amounts): Three months ended March 31, 2022 2021 Numerator: Net income attributable to Tanger Factory Outlet Centers, Inc. $ 20,518 $ 4,133 Less allocation of earnings to participating securities (215) (207) Net income available to common shareholders of Tanger Factory Outlet Centers, Inc. $ 20,303 $ 3,926 Denominator: Basic weighted average common shares 103,520 94,812 Effect of notional units 802 288 Effect of outstanding options 736 717 Diluted weighted average common shares 105,058 95,817 Basic earnings per common share: Net income $ 0.20 $ 0.04 Diluted earnings per common share: Net income $ 0.19 $ 0.04 We determine diluted earnings per share based on the weighted average number of common shares outstanding combined with the incremental weighted average shares that would have been outstanding assuming all potentially dilutive securities were converted into common shares at the earliest date possible. Notional units granted under our equity compensation plan are considered contingently issuable common shares and are included in earnings per share if the effect is dilutive using the treasury stock method and the common shares would be issuable if the end of the reporting period were the end of the contingency period. For the three months ended March 31, 2022, approximately 139,000 notional units were excluded from the computation and for the three months ended March 31, 2021, approximately 1.1 million notional units were excluded from the computation because these notional units either would not have been issuable if the end of the reporting period were the end of the contingency period or as they were anti-dilutive. With respect to outstanding options, the effect of dilutive common shares is determined using the treasury stock method, whereby outstanding options are assumed exercised at the beginning of the reporting period and the exercise proceeds from such options and the average measured but unrecognized compensation cost during the period are assumed to be used to repurchase our common shares at the average market price during the period. For the three months ended March 31, 2022, approximately 297,000 options were excluded from the computation and for the three months ended March 31, 2021, approximately 403,000 options were excluded from the computation, as they were anti-dilutive. The assumed exchange of the partnership units held by the Non-Company LPs as of the beginning of the year, which would result in the elimination of earnings allocated to the noncontrolling interest in the Operating Partnership, would have no impact on earnings per share since the allocation of earnings to a common limited partnership unit, as if exchanged, is equivalent to earnings allocated to a common share. Certain of the Company’s unvested restricted common share awards contain non-forfeitable rights to dividends or dividend equivalents. The impact of these unvested restricted common share awards on earnings per share has been calculated using the two-class method whereby earnings are allocated to the unvested restricted common share awards based on dividends declared and the unvested restricted common shares’ participation rights in undistributed earnings. Unvested restricted common shares that do not contain non-forfeitable rights to dividends or dividend equivalents are included in the diluted earnings per share computation if the effect is dilutive, using the treasury stock method.

Share-based Payment Arrangement [Abstract]
Equity-Based Compensation of the Company	Equity-Based Compensation of the Company We have a shareholder approved equity-based compensation plan, the Incentive Award Plan of Tanger Factory Outlet Centers, Inc. and Tanger Properties Limited Partnership (as amended and restated on April 4, 2014), as amended (the “Plan”), which covers our non-employee directors, officers, employees and consultants. Per the Operating Partnership agreement, when a common share is issued by the Company, the Operating Partnership issues one corresponding unit of partnership interest to the Company’s wholly-owned subsidiary, the Tanger LP Trust. Therefore, when the Company grants an equity-based award, the Operating Partnership treats each award as having been granted by the Operating Partnership. In the discussion below, the term “we” refers to the Company and the Operating Partnership together and the term “shares” is meant to also include corresponding units of the Operating Partnership. We recorded equity-based compensation expense in general and administrative expenses in our consolidated statements of operations as follows (in thousands): Three months ended March 31, 2022 2021 Restricted common shares (1) $ 1,569 $ 2,573 Notional unit performance awards (1) 1,045 1,149 Options 94 123 Total equity-based compensation $ 2,708 $ 3,845 (1) The three months ended March 31, 2021, includes the accelerated recognition of compensation cost. Equity-based compensation expense capitalized as a part of rental property and deferred lease costs were as follows (in thousands): Three months ended March 31, 2022 2021 Equity-based compensation expense capitalized $ 38 $ 64 Restricted Common Share and Restricted Share Unit Awards During February 2022, the Company granted approximately 383,000 restricted common shares and restricted share units to the Company’s non-employee directors and the Company’s executive officers. The grant date fair value of the awards was $16.62 per share. The restricted common shares vest ratably over a three year period on January 4th of each year for non-employee directors and on February 15th of each year for executive officers. Compensation expense related to the amortization of the deferred compensation is being recognized in accordance with the vesting schedule of the restricted shares. For certain shares that vest during the period, we withhold shares with value equivalent up to the employees’ maximum statutory obligation for the applicable income and other employment taxes, and remit cash to the appropriate taxing authorities. The total number of shares withheld upon vesting were approximately 130,000 and 112,000 for the three months ended March 31, 2022 and 2021, respectively. The total number of shares withheld was based on the value of the restricted common shares on the vesting date as determined by our closing share price on the day prior to the vesting date. Total amounts paid for the employees’ tax obligation to taxing authorities were $2.1 million and $1.6 million for the three months ended March 31, 2022 and 2021, respectively. These amounts are reflected as financing activities within the consolidated statements of cash flows. 2022 Performance Share Plan During February 2022, the Compensation Committee of the Company approved the general terms of the Tanger Factory Outlet Centers, Inc. 2022 Performance Share Plan (the “2022 PSP”) covering the Company's executive officers whereby a maximum of approximately 555,000 restricted common shares may be earned if certain share price appreciation goals are achieved over a three year measurement period. The 2022 PSP is a long-term incentive compensation plan. Recipients may earn units which may convert into restricted common shares of the Company based on the Company’s absolute share price appreciation (or absolute total shareholder return) and its share price appreciation relative to its peer group (or relative total shareholder return) over a three-year measurement period. Any shares earned at the end of the three-year measurement period are subject to a time-based vesting schedule, with 50% of the shares vesting immediately following the measurement period, and the remaining 50% vesting one year thereafter, contingent upon continued employment with the Company through the vesting date (unless terminated prior thereto (a) by the Company without cause, (b) by participant for good reason or, (c) due to death or disability). The following table sets forth 2022 PSP performance targets and other relevant information about the 2022 PSP: Performance targets (1) Absolute portion of award: Percent of total award 33.3% Absolute total shareholder return range 26.0 % - 40.5% Percentage of units to be earned 20 % - 100% Relative portion of award: Percent of total award 66.7% Percentile rank of peer group range (2) 30 th - 80th Percentage of units to be earned 20 % - 100% Maximum number of restricted common shares that may be earned 555,349 February grant date fair value per share $ 11.68 (1) The number of restricted common shares received under the 2022 PSP will be determined on a pro-rata basis by linear interpolation between total shareholder return thresholds, both for absolute total shareholder return and for relative total shareholder return amongst the Company’s peer group. (2) The peer group is based on companies included in the FTSE NAREIT Retail Index. The fair values of the 2022 PSP awards granted during the three months ended March 31, 2022 were determined at the grant dates using a Monte Carlo simulation pricing model and the following assumptions: Risk free interest rate (1) 1.7 % Expected dividend yield (2) 5.7 % Expected volatility (3) 65 % (1) Represents the interest rate as of the grant date on US treasury bonds having the same life as the estimated life of the restricted unit grants. (2) The dividend yield is calculated utilizing the average dividend yield over the previous three-year period and the current dividend yield as of the valuation date. (3) Based on a mix of historical and implied volatility for our common shares and the common shares of our peer index companies over the measurement period. 2019 Performance Share Plan On February 17, 2022, the measurement period for the 2019 Performance Share Plan (the “2019 PSP") expired. Based on the Company’s relative total shareholder return over the three year measurement period, we issued 96,592 restricted common shares in February 2022, with 58,569 vesting immediately and the remaining 38,023 vesting in February one year thereafter, contingent upon continued employment with the Company through the vesting date. Our absolute share price appreciation (or total shareholder return) for the 2019 OPP did not meet the minimum share price appreciation and no shares were earned under this component of the 2019 OPP.

New Accounting Pronouncements	New Accounting PronouncementsRecently issued accounting standardsOn March 12, 2020, the FASB issued Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or other reference rates expected to be discontinued because of reference rate reform. This ASU is effective as of March 12, 2020 through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848), which refines the scope of Topic 848 and clarifies some of its guidance. Specifically, certain provisions in Topic 848, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. Amendments to the expedients and exceptions in Topic 848 capture the incremental consequences of the scope clarification and tailor the existing guidance to derivative instruments affected by the discounting transition. The amendments are effective immediately for all entities. An entity may elect to apply the amendments on a full retrospective basis. We have not adopted any of the optional expedients or exceptions through March 31, 2022, but will continue to evaluate the possible adoption of any such expedients or exceptions during the effective period as circumstances evolve.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited consolidated financial statements included herein have been prepared pursuant to accounting principles generally accepted in the United States of America and should be read in conjunction with the consolidated financial statements and notes thereto of the Company’s and the Operating Partnership’s combined Annual Report on Form 10-K for the year ended December 31, 2021. The December 31, 2021 balance sheet data in this Form 10-Q was derived from audited financial statements. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the SEC’s rules and regulations, although management believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the financial statements for the interim periods have been made. The results of interim periods are not necessarily indicative of the results for a full year.
Consolidation	The Company currently consolidates the Operating Partnership because it has (1) the power to direct the activities of the Operating Partnership that most significantly impact the Operating Partnership’s economic performance and (2) the obligation to absorb losses and the right to receive the residual returns of the Operating Partnership that could be potentially significant. We consolidate properties that are wholly-owned and properties where we own less than 100% but control such properties. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities (“VIE”). For joint ventures that are determined to be a VIE, we consolidate the entity where we are deemed to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance, and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. Our determination of the primary beneficiary considers all relationships between us and the VIE, including management agreements and other contractual arrangements. Investments in real estate joint ventures that we do not control but may exercise significant influence on are accounted for using the equity method of accounting. These investments are recorded initially at cost and subsequently adjusted for our equity in the joint venture’s net income or loss, cash contributions, distributions and other adjustments required under the equity method of accounting. For certain investments in real estate joint ventures, we record our equity in the venture’s net income or loss under the hypothetical liquidation at book value method of accounting due to the structures and the preferences we receive on the distributions from our joint ventures pursuant to the respective joint venture agreements for those joint ventures. Under this method, we recognize income and loss in each period based on the change in liquidation proceeds we would receive from a hypothetical liquidation of our investment based on depreciated book value. Therefore, income or loss may be allocated disproportionately as compared to the ownership percentages due to specified preferred return rate thresholds and may be more or less than actual cash distributions received and more or less than what we may receive in the event of an actual liquidation. We separately report investments in joint ventures for which accumulated distributions have exceeded investments in, and our share of net income or loss of, the joint ventures within other liabilities in the consolidated balance sheets because we are committed to provide further financial support to these joint ventures. The carrying amount of our investments in the Charlotte, Columbus, Galveston/Houston, and National Harbor joint ventures are less than zero because of financing or operating distributions that were greater than net income, as net income includes non-cash charges for depreciation and amortization.
Accounts Receivable	Accounts ReceivableIndividual leases are assessed for collectability and upon the determination that the collection of rents is not probable, accrued rent and accounts receivable are written-off as an adjustment to rental revenue. Revenue from leases where collection is deemed to be less than probable is recorded on a cash basis until collectability is determined to be probable. Further we assess whether operating lease receivables, at a portfolio level, are appropriately valued based upon an analysis of balances outstanding, historical bad debt levels and current economic trends including discussions with tenants for potential lease amendments. Our estimate of the collectability of accrued rents and accounts receivable is based on the best information available to us at the time of preparing the financial statements. Straight-line rent adjustments recorded as a receivable in prepaids and other assets on the consolidated balance sheets was approximately $51.6 million as of March 31, 2022.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Rental property held and used by us is reviewed for impairment in the event that facts and circumstances indicate that the carrying amount of an asset may not be recoverable. In such an event, we compare the estimated future undiscounted cash flows associated with the asset to the asset's carrying amount, and if less, recognize an impairment loss in an amount by which the carrying amount exceeds its fair value.
Recently issued accounting standards	Recently issued accounting standardsOn March 12, 2020, the FASB issued Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or other reference rates expected to be discontinued because of reference rate reform. This ASU is effective as of March 12, 2020 through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848), which refines the scope of Topic 848 and clarifies some of its guidance. Specifically, certain provisions in Topic 848, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. Amendments to the expedients and exceptions in Topic 848 capture the incremental consequences of the scope clarification and tailor the existing guidance to derivative instruments affected by the discounting transition. The amendments are effective immediately for all entities. An entity may elect to apply the amendments on a full retrospective basis. We have not adopted any of the optional expedients or exceptions through March 31, 2022, but will continue to evaluate the possible adoption of any such expedients or exceptions during the effective period as circumstances evolve.
