Business	Business Tanger Factory Outlet Centers, Inc. and subsidiaries is one of the largest owners and operators of outlet centers in the United States and Canada. We are a fully-integrated, self-administered and self-managed real estate investment trust (“REIT”) which, through our controlling interest in the Operating Partnership, focuses exclusively on developing, acquiring, owning, operating and managing outlet shopping centers. As of June 30, 2019 , we owned and operated 32 consolidated outlet centers, with a total gross leasable area of approximately 12.0 million square feet. We also had partial ownership interests in 7 unconsolidated outlet centers totaling approximately 2.2 million square feet, including 3 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. The terms “we”, “our” and “us” refer to the Company or the Company and the Operating Partnership together, as the text requires. The Company owns the majority of the units of partnership interest issued by the Operating Partnership through its two wholly-owned subsidiaries, Tanger GP Trust and Tanger LP Trust. Tanger GP Trust is the sole general partner of the Operating Partnership. Tanger LP Trust holds a limited partnership interest.

Organization, Consolidation and Presentation of Financial Statements [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, 2018 . The December 31, 2018 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. Certain prior period balances in the accompanying unaudited consolidated statements of operations have been reclassified or combined to conform to the current period presentation. 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 (“HLBV”) 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.

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.

(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 Six months ended June 30, June 30, 2019 2018 2019 2018 Fee: Management and marketing $ 561 $ 565 $ 1,128 $ 1,133 Leasing and other fees 9 65 40 110 Expense reimbursements from unconsolidated joint ventures 675 512 1,419 1,097 Total Fees $ 1,245 $ 1,142 $ 2,587 $ 2,340 Expense reimbursements from unconsolidated joint ventures were previously included in expense reimbursements in our June 30, 2018 Form 10-Q. As these revenues are not related to leases, the 2018 amounts have been reclassified to management, leasing and other services on the consolidated statements of operations to conform to the current year presentation. See Note 17 for discussion of adoption of Accounting Standards Codification Topic 842 “Leases”. 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 “Summary 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 $3.9 million and $4.1 million as of June 30, 2019 and December 31, 2018 , respectively) are amortized over the various useful lives of the related assets. RioCan Canada In May 2019 , the RioCan joint venture closed on the sale of its outlet center in Bromont, for net proceeds of approximately $6.4 million . Our share of the proceeds was approximately $3.2 million . As a result of this transaction, we recorded a foreign currency loss of approximately $3.6 million in other income (expense), which had been previously recorded in other comprehensive income.

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 June 30, 2019: Asset: Interest rate swaps (prepaids and other assets) $ 1,842 $ — $ 1,842 $ — Total assets $ 1,842 $ — $ 1,842 $ — Liabilities: Interest rate swaps (other liabilities) $ 1,658 $ — $ 1,658 $ — Total liabilities $ 1,658 $ — $ 1,658 $ — 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, 2018: Asset: Interest rate swaps (prepaids and other assets) $ 5,755 $ — $ 5,755 $ — Total assets $ 5,755 $ — $ 5,755 $ — Liabilities: Interest rate swaps (other liabilities) $ 6 $ — $ 6 $ — Total liabilities $ 6 $ — $ 6 $ — Fair values of interest rate swaps are approximated 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): June 30, 2019 December 31, 2018 Level 1 Quoted Prices in Active Markets for Identical Assets or Liabilities $ — $ — Level 2 Significant Observable Inputs 1,139,946 1,085,138 Level 3 Significant Unobservable Inputs 454,808 583,337 Total fair value of debt $ 1,594,754 $ 1,668,475 Recorded value of debt $ 1,586,309 $ 1,712,918 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.

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.

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 June 30, Six months ended June 30, 2019 2018 2019 2018 Numerator: Net income attributable to Tanger Factory Outlet Centers, Inc. $ 13,727 $ 22,969 $ 76,058 $ 45,807 Less allocation of earnings to participating securities (114 ) (313 ) (725 ) (576 ) Net income available to common shareholders of Tanger Factory Outlet Centers, Inc. $ 13,613 $ 22,656 $ 75,333 $ 45,231 Denominator: Basic weighted average common shares 93,187 93,298 93,245 93,470 Diluted weighted average common shares 93,187 93,298 93,245 93,470 Basic earnings per common share: Net income $ 0.15 $ 0.24 $ 0.81 $ 0.48 Diluted earnings per common share: Net income $ 0.15 $ 0.24 $ 0.81 $ 0.48 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. There were no securities which had a dilutive effect on earnings per common share for the three months and six months ended June 30, 2019 and 2018 . 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 both the three and six months ended June 30, 2019 , approximately 1.1 million notional units were excluded from the computation and for both the three and six months ended June 30, 2018 approximately 1.0 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 both the three and six months ended June 30, 2019 , 526,000 options were excluded from the computation, and for both the three and six months ended June 30, 2018 , approximately 558,000 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.

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, the “Plan”), which covers our non-employee directors, officers, employees and consultants. For each common share issued by the Company, the Operating Partnership issues one corresponding unit of partnership interest to the Company’s wholly-owned subsidiaries. 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 Six months ended June 30, June 30, 2019 2018 2019 2018 Restricted common shares (1) $ 4,627 $ 2,366 $ 7,140 $ 4,855 Notional unit performance awards (1) 2,314 1,014 3,576 1,998 Options 41 99 84 192 Total equity-based compensation $ 6,982 $ 3,479 $ 10,800 $ 7,045 (1) Includes the accelerated recognition of compensation cost related to the planned retirement of an executive officer. Equity-based compensation expense capitalized as a part of rental property and deferred lease costs were as follows (in thousands): Three months ended Six months ended June 30, June 30, 2019 2018 2019 2018 Equity-based compensation expense capitalized $ 96 $ 461 $ 188 $ 552 Restricted Common Share and Restricted Share Unit Awards During February 2019, the Company granted approximately 309,000 in restricted common shares and restricted share units to the Company’s non-employee directors and the Company’s senior executive officers. The grant date fair value of the awards ranged from $19.01 to $21.73 per share. The non-employee directors’ restricted common shares vest ratably over a three year period and the senior executive officers’ restricted shares (other than our Chief Executive Officer’s) vest ratably over a three or five year period. Our Chief Executive Officer’s restricted shares vest on the first anniversary of the grant date and his restricted share units vest in two equal installments on the second and third anniversaries of the grant date. For the restricted shares and units issued to our Chief Executive Officer, the award agreements require him to hold shares or units issued to him for a minimum of three years following vesting or the share issuance date, as applicable. 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 81,000 and 89,000 for the six months ended June 30, 2019 and 2018 , 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 $1.8 million for the six months ended June 30, 2019 and $2.1 million for the six months ended June 30, 2018 . These amounts are reflected as financing activities within the consolidated statements of cash flows. 2019 Outperformance Plan In February 2019, the Compensation Committee of the Company approved the general terms of the Tanger Factory Outlet Centers, Inc. 2019 Outperformance Plan (the “2019 OPP”). The 2019 OPP 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, with respect to our Chief Executive Officer, retirement or (c) due to death or disability). The following table sets forth 2019 OPP performance targets and other relevant information about the 2019 OPP: Performance targets (1) Absolute portion of award: Percent of total award 33.3% Absolute total shareholder return range 19.1% - 29.5% 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) 30th - 80th Percentage of units to be earned 20%-100% Maximum number of restricted common shares that may be earned 531,827 Grant date fair value per share $ 12.09 (1) The number of restricted common shares received under the 2019 OPP 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 2019 OPP awards granted during the six months ended June 30, 2019 were determined at the grant dates using a Monte Carlo simulation pricing model and the following assumptions: Risk free interest rate (1) 2.6 % Expected dividend yield (2) 5.3 % Expected volatility (3) 24 % (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 dividends paid for the previous five-year period. (3)

Leases [Abstract]
Leases	Leases On January 1, 2019, we adopted ASC 842, which supersedes ASC 840. We adopted ASC 842 using the modified retrospective approach, whereby there was no cumulative effect adjustments to retained earnings on adoption and prior periods were not restated. Accordingly, our leases and lease related costs, as both lessee and lessor, and lease related receivables, as lessor, are presented under ASC 842 as of and for the three and six months ended June 30, 2019 and under ASC 840 as of December 31, 2018 and for the three and six months ended June 30, 2018. As a lessor, substantially all of our revenues are earned from arrangements that are within the scope of ASC 842. We utilized the practical expedient in ASU 2018-11 to account for lease and non-lease components as a single component which resulted in all of our revenues associated with leases being recorded as rental revenues in the consolidated statements of operations. As a result of the adoption of ASC 842, the amounts disclosed in our 2018 second quarter 10-Q as base rentals, percentage rentals and expense reimbursements have now been combined into rental revenues on the consolidated statements of operations to conform to the current year presentation. In addition, certain amounts previously included in expense reimbursements in our 2018 second quarter 10-Q, which are not related to leases have been reclassified to management, leasing and other services on the consolidated statements of operations to conform to the current year presentation. See Note 4 for additional details. ASC 842 requires certain other accounting changes effective January 1, 2019 where prior year amounts are not reclassified or restated. Uncollectible tenant revenues previously recorded in general and administrative expense are recorded in rental revenues as a contra-revenue account in 2019. As a result of combining all components of a lease, all fixed contractual payments, including consideration received from certain executory costs, are now recognized on a straight line basis. For the three and six months ended June 30, 2019 , we recorded a straight-line rent adjustment of $1.7 million and $3.2 million , respectively, in rental revenues in our consolidated statements of operations to record revenues from executory costs on a straight-line basis. In addition, direct internal leasing costs are capitalized, however, indirect internal leasing costs previously capitalized are now expensed. We only capitalize the portion of these types of costs incurred that are a direct result of an executed lease. For the three and six months ended June 30, 2019 , lease costs of approximately $1.1 million and $2.1 million , respectively, were expensed which would have been capitalized under ASC 840. As a lessee, the new standard also provides a number of optional provisions, known as practical expedients, which companies may elect to adopt to facilitate implementation. We elected the package of practical expedients which, among other items, precludes us from needing to reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification of any expired or existing leases, and (3) initial direct costs for any existing leases. Information as Lessor Under ASC 842 As of June 30, 2019 , we were the lessor to over 2,300 stores in our 32 consolidated outlet centers, under operating leases with initial terms that expire from 2019 to 2032 , with certain agreements containing extension options. We also have certain agreements which require tenants to pay their portion of reimbursable expenses such as common area expenses, utilities, insurance and real estate taxes. For the three and six months ended June 30, 2019 , the components of rental revenues are as follows (in thousands): Three months ended June 30, 2019 Six months ended June 30, 2019 Rental revenues - fixed $ 89,262 $ 182,721 Rental revenues - variable (1) 23,123 49,618 Rental revenues $ 112,385 $ 232,339 (1) Primarily includes rents based on a percentage of tenant sales volume and reimbursable expenses such as common area expenses, utilities, insurance and real estate taxes. Future minimum lease receipts under non-cancelable operating leases as of June 30, 2019 , excluding the effect of straight-line rent and variable rentals, are as follows (in thousands): For the remainder of 2019 $ 161,791 2020 315,266 2021 278,847 2022 243,310 2023 209,258 2024 173,803 Thereafter 325,913 $ 1,708,188 Information as Lessor Under ASC 840 As of December 31, 2018, we were the lessor to over 2,600 stores in our 36 consolidated outlet centers, under operating leases with initial terms that expire from 2019 to 2033. The majority of our leases contain provisions which provide additional rents based on tenants’ sales volume. Percentage rentals are recognized when specified targets that trigger the contingent rent are met. Future minimum lease receipts under non-cancelable operating leases as of December 31, 2018, excluding the effect of straight-line rent and variable rentals, are as follows (in thousands): 2019 $ 285,343 2020 265,361 2021 229,553 2022 195,808 2023 164,845 Thereafter 364,844 $ 1,505,754 Information as Lessee Under ASC 842 Adoption of the new standard resulted in the recording of operating lease right-of-use assets and operating lease liabilities, of $90.4 million and $95.1 million , respectively, as of January 1, 2019 equal to the present value of the minimum lease payments required under each lease. The difference between the recorded operating lease liability and operating right-of-use assets represents the accrued straight-line rent liability and our prepaid rent balances previously recognized under ASC 840. In March 2019, we sold our Ocean City outlet center, which had an operating lease right-of-use asset and operating lease liability of approximately $2.5 million . Our non-cancelable operating leases, with terms in excess of one year, have terms, including certain extension options, that expire from 2028 to 2101. Certain extension options, which are reasonably certain at inception, are used in the calculation of our operating lease right-of-use assets based on the economic life of the asset. Leases with an initial term of 12 months or less (short-term leases) are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. The majority of our operating lease expense is related to ground leases at the following outlet centers: Myrtle Beach Hwy 17, Atlantic City, Sevierville, Riverhead, Foxwoods and Rehoboth Beach and the lease of our corporate office in Greensboro, North Carolina. For the three and six months ended June 30, 2019 , the components of lease costs are as follows (in thousands): Three months ended Six months ended Operating lease costs $ 1,372 $ 2,776 Short-term lease costs 571 1,163 Variable lease costs (1) 53 131 Total lease costs $ 1,996 $ 4,070 (1) Our variable lease costs relate to our ground leases where increases in payments are based on center financial performance. The discount rate applied to measure each operating lease right-of-use asset and operating lease liability is based on our incremental borrowing rate (“IBR”). We consider the general economic environment and our credit rating and factor in various financing and asset specific adjustments to ensure the IBR is appropriate based on the intended use of the underlying lease. The lease term and discount rates are as follows: June 30, 2019 Weighted - average remaining lease term (years) 50 Weighted - average discount rate 5.0 % Cash flow information related to leases for the six months ended June 30, 2019 (in thousands): June 30, 2019 Operating cash outflows related to operating leases $ 2,788 Maturities of lease liabilities as of June 30, 2019 for the next five years and thereafter are as follows (in thousands): For the remainder of 2019 $ 2,782 2020 5,568 2021 5,613 2022 5,669 2023 5,709 2024 5,765 Thereafter 226,837 Total lease payments $ 257,943 Less imputed interest 165,851 Present value of lease liabilities $ 92,092 Information as Lessee Under ASC 840 As of December 31, 2018, our non-cancelable operating leases have terms, including certain extension options, that expire from 2019 to 2101. Rental payments for these leases totaled approximately $1.8 million and $3.6 million , respectively for the three and six months ended June 30, 2018. As of December 31, 2018, the majority of our rental payments are related to ground leases at the following outlet centers: Myrtle Beach Hwy 17, Atlantic City, Ocean City, Sevierville, Riverhead, Foxwoods and Rehoboth Beach and the lease of our corporate office in Greensboro, North Carolina. The contingent portion of our ground lease payments is based on center performance and/or changes in an index. For operating leases as of December 31, 2018, minimum lease payments for the next five years and thereafter are as follows (in thousands): 2019 $ 7,526 2020 7,311 2021 7,140 2022 7,127 2023 7,167 Thereafter 258,438 Total minimum payment $ 294,709

New Accounting Pronouncements	New Accounting Pronouncements Recently adopted accounting standards (other than ASC 842 Leases) In October 2018, the FASB issued Accounting Standards Update (“ASU”) 2018-16, Inclusion of the Secured Overnight Financing Rate (“SOFR”) Overnight Index Swap (“OIS”) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes to Accounting Standards Codification 815. ASU 2018-16 expands the list of U.S. benchmark interest rates permitted in the application of hedge accounting by adding the OIS rate based on SOFR as an eligible benchmark interest rate. The mandatory effective date for calendar year-end public companies was January 1, 2019. The adoption of ASU 2018-16 as of January 1, 2019 did not have a material impact on our consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. ASU 2018-07 amends prior employee share-based payment guidance to include nonemployee share-based payment transactions for acquiring services or property. This ASU now aligns the determination of the measurement date, the accounting for performance conditions, and the accounting for share-based payments after vesting in addition to other items. The provisions of ASU 2018-07 were effective for us as of January 1, 2019 using a modified transition method upon adoption, and early adoption was permitted. The adoption of ASU 2018-07 as of January 1, 2019 did not have a material impact on our consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. The new guidance made more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amended the presentation and disclosure requirements and changed how companies assess effectiveness. It is intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The adoption of ASU 2017-12 as of January 1, 2019 did not have a material impact on our consolidated financial statements. Recently issued accounting standards to be adopted In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 is intended to improve the effectiveness of disclosures required by entities regarding recurring and nonrecurring fair value measurements. ASU 2018-13 is effective for reporting periods beginning after December 15, 2019, with early adoption permitted. The adoption of ASU 2018-13 will not have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13 to amend the accounting for credit losses for certain financial instruments. Under the new guidance, an entity recognizes its estimate of expected credit losses as an allowance, which the FASB believes will result in more timely recognition of such losses. In November 2018, the FASB released ASU No. 2018-19 “Codification Improvements to Topic 326, Financial Instruments - Credit Losses.” This ASU clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20 “Financial Instruments - Credit Losses.” Instead, impairment of receivables arising from operating leases should be accounted for under Subtopic 842-30 “Leases - Lessor.” ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The adoption of this new guidance will not have a material impact on our consolidated financial statements.

Accounting Policies [Abstract]
Basis of Accounting	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, 2018 . The December 31, 2018 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 (“HLBV”) 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.
