Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization of the Company	Organization of the Company Tanger Factory Outlet Centers, Inc. and subsidiaries, which we refer to as the Company, 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 December 31, 2016 , we owned and operated 36 consolidated outlet centers, with a total gross leasable area of approximately 12.7 million square feet. All references to gross leasable area, square feet, occupancy, stores and store brands contained in the notes to the consolidated financial statements are unaudited. These outlet centers were 98% occupied and contained over 2,600 stores, representing approximately 400 store brands. We also had partial ownership interests in 8 unconsolidated outlet centers totaling approximately 2.3 million square feet, including 4 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, which we refer to as the Operating Partnership. 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 controls the Operating Partnership as its sole general partner. Tanger LP Trust holds a limited partnership interest. As of December 31, 2016 , the Company, through its ownership of Tanger GP Trust and Tanger LP Trust, owned 96,095,891 units of the Operating Partnership and other limited partners (the "Non-Company LPs") collectively owned 5,027,781 Class A common limited partnership units. Each Class A common limited partnership unit held by the Non-Company LPs is exchangeable for one of the Company's common shares, subject to certain limitations to preserve the Company's status as a REIT. Class B common limited partnership units, which are held by Tanger LP Trust, are not exchangeable for common shares of the Company.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation - The consolidated financial statements of the Company include its accounts and its consolidated subsidiaries, as well as the Operating Partnership and its consolidated subsidiaries. The consolidated financial statements of the Operating Partnership include its accounts and its consolidated subsidiaries. Intercompany balances and transactions have been eliminated in 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 or properties where we own less than 100% but we control. 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 various factors including the form of our ownership interest, our representation in an entity's governance, the size of our investment, our ability to participate in policy making decisions and the rights of the other investors to participate in the decision making process to replace us as manager and or liquidate the venture, if applicable. 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 venture's net income or loss, cash contributions, distributions and other adjustments required under the equity method of accounting. For certain of these investments, 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. In the event a basis difference is created between our underlying interest in the venture's net assets and our initial investment, we amortize such amount over the estimated life of the venture as a component of equity in earnings of unconsolidated joint ventures. 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 and Galveston/Houston 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 Company's consolidated financial statements, the “Noncontrolling interests in 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. Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Estimates are used in the calculations of impairment losses, costs capitalized to originate operating leases, costs incurred for the construction and development of properties, and the values of deferred lease costs and other intangibles related to the acquisition of properties. Actual results could differ from those estimates. Operating Segments - We focus exclusively on developing, acquiring, owning, operating, and managing outlet shopping centers. We aggregate the financial information of all outlet centers into one reportable operating segment because the outlet centers all have similar economic characteristics and provide similar products and services to similar types and classes of customers. Rental Property - Rental properties are recorded at cost less accumulated depreciation. Buildings, improvements and fixtures consist primarily of permanent buildings and improvements made to land such as infrastructure and costs incurred in providing rental space to tenants. The pre-construction stage of project development involves certain costs to secure land control and zoning and complete other initial tasks essential to the development of the project. These costs are transferred from other assets to construction in progress when the pre-construction tasks are completed. Costs of unsuccessful pre-construction efforts are expensed when the project is no longer probable and, if significant, are recorded as abandoned pre-development costs in the consolidated statement of operations. We also capitalize other costs incurred for the construction and development of properties, including interest, real estate taxes and payroll and related costs associated with employees directly involved. Capitalization of costs commences at the time the development of the property becomes probable and ceases when the property is substantially completed and ready for its intended use. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portion under construction. The amount of payroll and related costs capitalized for the construction and development of properties is based on our estimate of the amount of costs directly related to the construction or development of these assets. Interest costs are capitalized during periods of active construction for qualified expenditures based upon interest rates in place during the construction period until construction is substantially complete. This includes interest incurred on funds invested in or advanced to unconsolidated joint ventures for qualifying development activities until placed in service. Payroll and related costs and interest costs capitalized for the years ended December 31, 2016 , 2015 and 2014 were as follows (in thousands): 2016 2015 2014 Payroll and related costs capitalized $ 2,095 $ 2,989 $ 1,543 Interest costs capitalized $ 2,259 $ 3,448 $ 5,095 Depreciation is computed on the straight-line basis over the estimated useful lives of the assets. We generally use estimated lives of 33 years for buildings and improvements, 15 years for land improvements and 7 years for equipment. Tenant finishing allowances are amortized over the life of the associated lease. Capitalized interest costs are amortized over lives which are consistent with the constructed assets. Expenditures for ordinary maintenance and repairs are charged to operations as incurred while significant renovations and improvements which improve and/or extend the useful life of the asset are capitalized and depreciated over their estimated useful life. Depreciation expense related to rental property included in net income for each of the years ended December 31, 2016 , 2015 and 2014 was as follows (in thousands): 2016 2015 2014 Depreciation expense related to rental property $ 96,813 $ 85,872 $ 80,057 In accordance with accounting guidance for business combinations, we allocate the purchase price of acquisitions based on the fair value of land, building, tenant improvements, debt and deferred lease costs and other intangibles, such as the value of leases with above or below market rents, origination costs associated with the in-place leases, the value of in-place leases and tenant relationships, if any. We depreciate the amount allocated to building, deferred lease costs and other intangible assets over their estimated useful lives, which range up to 33 years. The values of the above and below market leases are amortized and recorded as either an increase (in the case of below market leases) or a decrease (in the case of above market leases) to rental income over the remaining term of the associated lease. The values of below market leases that are considered to have renewal periods with below market rents are amortized over the remaining term of the associated lease plus the renewal periods when the renewal is deemed probable to occur. The value associated with in-place leases is amortized over the remaining lease term and tenant relationships is amortized over the expected term, which includes an estimated probability of the lease renewal. If a tenant terminates its lease prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangibles is written off. The tenant improvements and origination costs are amortized as an expense over the remaining life of the lease (or charged against earnings if the lease is terminated prior to its contractual expiration date). We assess fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. These cash flow projections may be derived from various observable and unobservable inputs and assumptions. Also, we may utilize third-party valuation specialists. As a part of acquisition accounting, the amount by which the fair value of our previously held equity method investment exceeds the carrying book value is recorded as a gain on previously held interest in acquired joint venture. Direct costs to acquire existing outlet centers are expensed as incurred. Cash, Cash Equivalents and Restricted Cash - All highly liquid investments with an original maturity of three months or less at the date of purchase are considered to be cash equivalents. Cash balances at a limited number of banks may periodically exceed insurable amounts. We believe that we mitigate our risk by investing in or through major financial institutions. At December 31, 2016 and 2015 , we had cash equivalent investments in highly liquid money market accounts at major financial institutions of $672,000 and $671,000 , respectively. The restricted cash represents the cash proceeds from property sales that are being held by a qualified intermediary in anticipation of such amounts subsequently being invested in a tax efficient manner under Section 1031 of the Internal Revenue Code of 1986, as amended. Deferred Charges - Deferred charges include deferred lease costs and other intangible assets consisting of fees and costs incurred to originate operating leases and are amortized over the expected lease term. Deferred lease costs capitalized, including amounts paid to third-party brokers and payroll and related costs of employees directly involved in originating leases for the years ended December 31, 2016 , 2015 and 2014 were as follows (in thousands): 2016 2015 2014 Deferred lease costs capitalized $ 7,013 $ 7,803 $ 6,199 Of the amounts capitalized during 2016 , 2015 and 2014 the following were related to payroll and related costs (in thousands): 2016 2015 2014 Deferred lease costs capitalized- payroll and related costs $ 6,210 $ 6,236 $ 5,084 The amount of payroll and related costs capitalized is based on our estimate of the time and amount of costs directly related to originating leases. Deferred lease costs and other intangible assets also include the value of leases and origination costs deemed to have been acquired in real estate acquisitions. Deferred financing costs - Deferred financing costs include fees and costs incurred to obtain long-term financing and are amortized over the terms of the respective loans. Unamortized deferred financing costs are charged to expense when debt is retired before the maturity date. Captive Insurance - We have a wholly-owned captive insurance company that is responsible for losses up to certain deductible levels per occurrence for property damage (including wind damage from hurricanes) prior to third-party insurance coverage. Insurance losses are reflected in property operating expenses and include estimates of costs incurred, both reported and unreported. Impairment of Long-Lived Assets - Rental property held and used by us is reviewed for impairment in the event that facts and circumstances indicate 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 than such carrying amount, recognize an impairment loss in an amount by which the carrying amount exceeds its fair value. Fair value is determined using an income approach whereby we consider the prevailing market income capitalization rates and stabilized net operating income projections. We recognized no impairment losses for our consolidated properties during the years ended December 31, 2016 , 2015 , and 2014 , respectively. See Note 6 for discussion of the impairment of our unconsolidated joint venture at the Bromont, Quebec outlet center during 2016. Rental Property Held For Sale - Rental properties designated as held for sale are stated at the lower of their carrying value or their fair value less costs to sell. We classify rental property as held for sale when our Board of Directors approves the sale of the assets and it meets the requirements of current accounting guidance. Subsequent to this classification, no further depreciation is recorded on the assets. Impairment of Investments - On a periodic basis, we assess whether there are any indicators that the value of our investments in unconsolidated joint ventures may be impaired. An investment is impaired only if management's estimate of the value of the investment is less than the carrying value of the investments, and such decline in value is deemed to be other than temporary. To the extent impairment has occurred, the loss shall be measured as the excess of the carrying amount of the investment over the value of the investment. Our estimates of value for each joint venture investment are based on a number of assumptions that are subject to economic and market uncertainties including, among others, estimated hold period, terminal capitalization rates, demand for space, competition for tenants, discount and capitalization rates, changes in market rental rates and operating costs of the property. As these factors are difficult to predict and are subject to future events that may alter our assumptions, the values estimated by us in our impairment analysis may not be realized. Sales of Real Estate - For sales transactions meeting the requirements for full profit recognition, the related assets and liabilities are removed from the balance sheet and the resulting gain or loss is recorded in the period the transaction closes. For sales transactions with continuing involvement after the sale, if the continuing involvement with the property is limited by the terms of the sales contract, profit is recognized at the time of sale and is reduced by the maximum exposure to loss related to the nature of the continuing involvement. Sales to entities in which we have or receive an interest are accounted for using partial sale accounting. For transactions that do not meet the criteria for a sale, we evaluate the nature of the continuing involvement, including put and call provisions, if present, and account for the transaction as a financing arrangement, profit-sharing arrangement, leasing arrangement or other alternate method of accounting, rather than as a sale, based on the nature and extent of the continuing involvement. Some transactions may have numerous forms of continuing involvement. In those cases, we determine which method is most appropriate based on the substance of the transaction. Discontinued Operations - Properties that are sold or classified as held for sale are classified as discontinued operations provided that the disposal represents a strategic shift that has (or will have) a major effect on our operations and financial results (e.g., a disposal of a major geographical area, a major line of business, a major equity method investment or other major parts of an entity). Derivatives - We selectively enter into interest rate protection agreements to mitigate the impact of changes in interest rates on our variable rate borrowings. The notional amounts of such agreements are used to measure the interest to be paid or received and do not represent the amount of exposure to loss. None of these agreements are used for speculative or trading purposes. We recognize all derivatives as either assets or liabilities in the consolidated balance sheets and measure those instruments at their fair value. We also measure the effectiveness, as defined by the relevant accounting guidance, of all derivatives. We formally document our derivative transactions, including identifying the hedge instruments and hedged items, as well as our risk management objectives and strategies for entering into the hedge transaction. At inception and on a quarterly basis thereafter, we assess the effectiveness of derivatives used to hedge transactions. If a cash flow hedge is deemed effective, we record the change in fair value in other comprehensive income (loss). If after assessment it is determined that a portion of the derivative is ineffective, then that portion of the derivative's change in fair value will be immediately recognized in earnings. Income Taxes - We operate in a manner intended to enable the Company to qualify as a REIT under the Internal Revenue Code. A REIT which distributes at least 90% of its taxable income to its shareholders each year and which meets certain other conditions is not taxed on that portion of its taxable income which is distributed to its shareholders. We intend to continue to qualify as a REIT and to distribute substantially all of the Company's taxable income to its shareholders. Accordingly, no provision has been made in the Company's consolidated financial statements for Federal income taxes. As a partnership, the allocated share of income or loss for the year with respect to the Operating Partnership is included in the income tax returns for the partners; accordingly, no provision has been made for Federal income taxes in the Operating Partnership's consolidated financial statements. In addition, we continue to evaluate uncertain tax positions. The tax years 2013 - 2016 remain open to examination by the major tax jurisdictions to which we are subject. With regard to the Company's unconsolidated Canadian joint ventures, deferred tax assets result principally from depreciation deducted under United States Generally Accepted Accounting Principles ("GAAP") that exceed capital cost allowances claimed under Canadian tax rules. A valuation allowance is provided if we believe all or some portion of the deferred tax asset may not be realized. We have determined that a full valuation allowance is required as we believe none of the deferred tax assets will be realized. For income tax purposes, distributions paid to the Company's common shareholders consist of ordinary income, capital gains, return of capital or a combination thereof. Dividends per share for the years ended December 31, 2016 , 2015 and 2014 were taxable as follows: Common dividends per share: 2016 2015 2014 Ordinary income $ 1.246 $ 1.285 $ 0.765 Capital gain 0.014 0.020 — Return of capital — — 0.180 $ 1.260 $ 1.305 $ 0.945 The following reconciles net income available to the Company's shareholders to taxable income available to common shareholders for the years ended December 31, 2016 , 2015 and 2014 (in thousands): 2016 2015 2014 Net income available to the Company's shareholders $ 193,744 $ 211,200 $ 74,011 Book/tax difference on: Depreciation and amortization 1,666 12,446 20,575 Sale of assets and interests in unconsolidated entities (8,688 ) (110,248 ) (9,524 ) Equity in earnings from unconsolidated joint ventures 4,305 6,772 12,910 Share-based payment compensation 4,596 4,751 (37,193 ) Gain on previously held interest in acquired joint venture (91,467 ) — — Other differences 6,294 (2,831 ) 1,205 Taxable income available to common shareholders $ 110,450 $ 122,090 $ 61,984 Revenue Recognition - Base rentals are recognized on a straight-line basis over the term of the lease. Straight-line rent adjustments recorded as a receivable in other assets on the consolidated balance sheets were approximately $46.8 million and $40.6 million as of December 31, 2016 and 2015 , respectively. As a provision of a tenant lease, if we make a cash payment to the tenant for purposes other than funding the construction of landlord assets, we defer the amount of such payments as a lease incentive. We amortize lease incentives as a reduction of base rental revenue over the term of the lease. Substantially all leases contain provisions which provide additional rents based on tenants' sales volume (“percentage rentals”) and reimbursement of the tenants' share of advertising and promotion, common area maintenance, insurance and real estate tax expenses. Percentage rentals are recognized when specified targets that trigger the contingent rent are met. Expense reimbursements are recognized in the period the applicable expenses are incurred. For certain tenants, we receive a fixed payment for common area maintenance ("CAM") which is recognized as revenue when earned. When not reimbursed by the fixed-CAM component, CAM expense reimbursements are based on the tenant's proportionate share of the allocable operating expenses for the property. Payments received from the early termination of leases are recognized as revenue from the time the payment is receivable until the tenant vacates the space. The values of the above and below market leases are amortized and recorded as either an increase (in the case of below market leases) or a decrease (in the case of above market leases) to rental income over the remaining term of the associated lease. If a tenant terminates its lease prior to the original contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related above or below market lease value will be written off. We receive development, leasing, loan guarantee, management and marketing fees from third parties and unconsolidated affiliates for services provided to properties held in joint ventures. Development and leasing fees received from unconsolidated affiliates are recognized as revenue when earned to the extent of the third party partners' ownership interest. Development and leasing fees earned to the extent of our ownership interest are recorded as a reduction to our investment in the unconsolidated affiliate. Loan guarantee fees are recognized over the term of the guarantee. Management fees and marketing fees are recognized as revenue when earned. Fees recognized from these activities are shown as management, leasing and other services in our consolidated statements of operations. Fees received from consolidated joint ventures are eliminated in consolidation. Concentration of Credit Risk - We perform ongoing credit evaluations of our tenants. Although the tenants operate principally in the retail industry, the properties are geographically diverse. No single tenant accounted for 10% or more of combined base and percentage rental income or gross leasable area during 2016 , 2015 or 2014 . Supplemental Cash Flow Information - We purchase capital equipment and incur costs relating to construction of new facilities, including tenant finishing allowances. Expenditures included in accounts payable and accrued expenses were as follows for the years ended December 31, 2016 , 2015 and 2014 (in thousands): 2016 2015 2014 Costs relating to construction included in accounts payable and accrued expenses $ 22,908 $ 28,665 $ 23,033 See Note 3, for additional non-cash information associated with our acquisitions of rental property. A non-cash financing activity that occurred during the 2015 period related to a special dividend of $21.2 million that was declared in December 2015 and paid in January 2016. Interest paid, net of interest capitalized was as follows for the years ended December 31, 2016 , 2015 and 2014 (in thousands): 2016 2015 2014 Interest paid, net of interest capitalized $ 50,270 $ 49,542 $ 55,379 Accounting for Equity-Based Compensation - We have a shareholder approved equity-based compensation plan, the Incentive Award Plan of Tanger Factory Outlet Centers and Tanger Properties Limited Partnership (Amended and Restated as of April 4, 2014) (the "Plan"), which covers our independent directors, officers and our employees. We may issue non-qualified options and other equity-based awards under the Plan. We account for our equity-based compensation plan under the fair value provisions of the relevant accounting guidance. Foreign Currency Translation - We have entered into a co-ownership agreement with RioCan Real Estate Investment Trust to develop and acquire outlet centers in Canada for which the functional currency is the local currency. The assets and liabilities related to our investments in Canada are translated from their functional currency into U.S. Dollars at the rate of exchange in effect on the balance sheet date. Income statement accounts are translated using the average exchange rate for the period. Our share of unrealized gains and losses resulting from the translation of these financial statements are reflected in equity as a component of accumulated other comprehensive income (loss) in the consolidated balance sheets. New Accounting Pronouncements - In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-01, Clarifying the Definition of a Business (Topic 805). ASU 2017-01 clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. ASU 2017-01 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted. The update should be applied prospectively. We plan to adopt ASU 2017-01 as of January 1, 2017 and do not expect the adoption to require any additional disclosures. We believe most of our future acquisitions of operating properties will qualify as asset acquisitions and most future transaction costs associated with these acquisitions will be capitalized. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This ASU requires that a statement of cash flows explain the change during the period in cash, cash equivalents, and amounts generally described as restricted cash. Amounts generally described as restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The update should be applied retrospectively to each period presented. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. We plan to adopt this pronouncement for our fiscal year beginning January 1, 2018, and the pronouncement will result in changes to our consolidated statements of cash flows such that restricted cash amounts will be included in the beginning-of-period and end-of-period cash and cash equivalents totals. In October 2016, the FASB issued ASU 2016-17, Interests Held through Related Parties That Are under Common Control. This ASU modifies existing guidance with respect to how a decision maker that holds an indirect interest in a VIE through a common control party determines whether it is the primary beneficiary of the VIE as part of the analysis of whether the VIE would need to be consolidated. Under this ASU, a decision maker would need to consider only its proportionate indirect interest in the VIE held through a common control party. As a result of this ASU, in certain cases, previous consolidation conclusions may change. This ASU is effective for fiscal years beginning after December 15, 2016. Since we have already adopted the amendments in ASU 2015-02 we are required to apply the amendments in this ASU, retrospectively to the beginning of 2016. We do not expect the adoption of ASU 2016-17 to have a material impact on the company's financial position, results of operations or cash flows. In August 2016, the FASB issued ASU No. 2016-15, the Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force), which finalizes Proposed ASU No. EITF-15F of the same name, and addresses stakeholders’ concerns regarding diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. This ASU is effective for fiscal years beginning after December 15, 2017 and for interim periods within those fiscal years, with early adoption permitted. The ASU should be adopted using a retrospective transition approach. We are currently evaluating the impact of adopting the new guidance, but we do not expect the adoption to have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires measurement and recognition of expected versus incurred credit losses for financial assets held. This ASU will be applied on a prospective basis for fiscal years and interim periods beginning after December 15, 2019, with early adoption permitted for fiscal years beginning and interim periods beginning after December 15, 2018. We are currently evaluating the impact of adopting the new guidance, but we do not expect the adoption to have a material impact on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on th

Acquisition of Rental Property [Abstract]
Acquisition of Rental Property	Acquisition of Rental Property 2016 Acquisitions Savannah In August 2016, the Savannah joint venture, which owned the outlet center in Pooler, Georgia distributed all outparcels along with $15.0 million in cash consideration to the other partner in exchange for the partner's ownership interest. We contributed the $15.0 million in cash consideration to the joint venture, which we funded with borrowings under our unsecured lines of credit. At the time of acquisition, the property was subject to a $96.9 million construction loan, with an interest rate of LIBOR + 1.65% , that would have matured in May 2017. In September 2016, we repaid the mortgage loan with borrowings under our unsecured lines of credit. The former joint venture is now wholly-owned by us and was consolidated in our financial results as of the acquisition date. Prior to this transaction, we owned a 50% legal interest in the joint venture since its formation and accounted for it under the equity method of accounting. However, due to preferred equity contributions we made to the joint venture, and the returns earned on those contributions, our estimated economic interest in the book value of the assets was approximately 98% . Therefore, substantially all of the earnings of the joint venture were previously recognized by us as equity in earnings of unconsolidated joint ventures. There was no contingent consideration associated with this acquisition. The joint venture incurred approximately $260,000 in third-party acquisition related costs for the acquisition of the venture partner's interest that were expensed as incurred. As a result of acquiring the remaining interest in the Savannah joint venture, we recorded a gain of $46.3 million which represented the difference between the carrying book value and the fair value of our previously held equity method investment in the joint venture. Non-cash investing activities related to the purchase of our partners' interest in the Savannah joint venture, include the assumption of debt totaling $96.9 million . In addition, rental property and lease related intangible assets and liabilities increased by a net of $46.3 million related to the fair value of our previously held interest in excess of our carrying amount; prepaids and other assets increased $250,000 and accounts payable and accrued expenses increased $2.1 million from the assumption of current assets and liabilities. Westgate In June 2016, we completed the purchase of our partners' interest in the Westgate joint venture, which owned the outlet center in Glendale, Arizona, for a total cash price of approximately $40.9 million . Prior to the transaction, we owned a 58% interest in the Westgate joint venture since its formation in 2012 and accounted for it under the equity method of accounting. The former joint venture is now wholly-owned by us and was consolidated in our financial results as of June 30, 2016. The total cash price included $39.0 million to acquire the 40% ownership interest held by the equity partner in the joint venture. We also purchased the remaining 2% noncontrolling ownership interests in the Westgate outlet center held in a consolidated partnership for a purchase price of $1.9 million . The acquisition of the noncontrolling ownership interest was recorded as an equity transaction and, as a result, the carrying balances of the noncontrolling interest were eliminated and the remaining difference between the purchase price and carrying balance was recorded as a reduction in additional-paid-in-capital. We funded the total purchase price with borrowings under our unsecured lines of credit. At the time of the acquisition, the property was subject to a $62.0 million mortgage loan, with an interest rate of LIBOR + 1.75% and a maturity in June 2017. In August 2016, we repaid the mortgage loan in full with proceeds from the public offering of $250.0 million in senior notes due 2026. There was no contingent consideration associated with this acquisition. We incurred approximately $127,000 in third-party acquisition related costs for the acquisition of our partners' interest in the Westgate joint venture that were expensed as incurred. As a result of acquiring the remaining interest in the Westgate joint venture, we recorded a gain of $49.3 million which represented the difference between the carrying book value and the fair value of our previously held equity method investment in the joint venture. Non-cash investing activities related to the purchase of our partners' interest in the Westgate joint venture, include the assumption of debt totaling $62.0 million . In addition, rental property and lease related intangible assets and liabilities increased by a net of $49.3 million related to the fair value of our previously held interest in excess of our carrying amount; prepaids and other assets increased $227,000 and accounts payable and accrued expenses increased $5.0 million from the assumption of current assets and liabilities. The following table illustrates the fair value of the aggregate consideration transferred to acquire the equity interests of the Savannah and Westgate properties at the acquisition date for the year ended 2016 (in thousands): Cash transferred for equity interests $ 54,000 Fair value of our previously held interests 145,581 Fair value of net assets $ 199,581 The following table illustrates the aggregate fair value of the amounts of the identifiable assets acquired and liabilities assumed and recognized at the acquisition date for the Savannah and Westgate properties acquired during the year ended 2016: Fair Value (in thousands) Weighted-Average Amortization Period (in years) Cash $ 8,781 Land 27,593 Buildings, improvements and fixtures 308,117 Deferred lease costs and other intangibles Above market lease value 15,882 7.2 Lease in place value 13,972 5.9 Lease and legal costs 10,264 6.4 Total deferred lease costs and other intangibles 40,118 Prepaids and other assets 477 Debt (158,994 ) Accounts payable and accrued expenses (7,183 ) Other liabilities (below market lease value) (19,328 ) 12.0 Total fair value of net assets $ 199,581 The fair values were determined based on an income approach, using a rental growth rate of 3.0% , a discount rate between 7.50% and 8.25% , and a terminal capitalization rate between 5.75% and 7.0% . The estimated fair values were determined to have primarily relied upon Level 3 inputs, as defined in Note 12. The Company has finalized the valuations and completed the purchase price allocations. During the measurement period, we adjusted the Westgate purchase price allocation based upon information that was received subsequent to the acquisition date that related to conditions that existed as of that date. This adjustment increased above market lease value by $1.6 million , and decreased buildings, improvements and fixtures by $5.6 million , below market lease value by $4.8 million , lease in place value by $628,000 and land by $150,000 . 2014 Acquisition In September 2011, we purchased substantially all of the economic interests in The Outlets at Hershey, a 248,000 square foot outlet center. A portion of the cash consideration paid to the buyer included a $6.2 million loan, which was included in other assets in the consolidated balance sheets, collateralized by their remaining ownership interest in the property. In October 2014, the loan was canceled in exchange for this remaining ownership interest in the property.

Equity Method Investments and 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 December 31, 2016 Joint Venture Outlet Center Location Ownership % Square Feet (in 000's) Carrying Value of Investment (in millions) Total Joint Venture Debt, Net (in millions) (1) Columbus Columbus, OH 50.0 % 355 $ 6.7 $ 84.2 National Harbor National Harbor, MD 50.0 % 341 4.1 86.1 RioCan Canada Various 50.0 % 901 117.3 11.1 $ 128.1 $ 181.4 Charlotte (3) Charlotte, NC 50.0 % 398 $ (2.5 ) $ 89.7 Galveston/Houston (3) Texas City, TX 50.0 % 353 (3.8 ) 64.9 $ (6.3 ) $ 154.6 As of December 31, 2015 Joint Venture Outlet Center Location Ownership % Square Feet (in 000's) Carrying Value of Investment (in millions) Total Joint Venture Debt, Net (in millions) (1) Columbus Columbus, OH 50.0 % — $ 21.1 $ — National Harbor National Harbor, MD 50.0 % 339 6.1 85.8 RioCan Canada Various 50.0 % 870 117.2 11.3 Savannah (2) Savannah, GA 50.0 % 377 44.4 87.6 Westgate Glendale, AZ 58.0 % 411 12.3 61.9 $ 201.1 $ 246.6 Charlotte (3) Charlotte, NC 50.0 % 398 $ (1.1 ) $ 89.6 Galveston/Houston (3) Texas City, TX 50.0 % 353 $ (1.5 ) $ 64.7 $ (2.6 ) $ 154.3 (1) Net of debt origination costs and including premiums of $1.6 million and $3.3 million as of December 31, 2016 and December 31, 2015, respectively. (2) Based on capital contribution and distribution provisions in the joint venture agreement, our economic interest in the venture's cash flow was greater than indicated in the Ownership column, which states our legal interest in this venture. As of December 31, 2015, based upon the liquidation proceeds we would have received from a hypothetical liquidation of our investment based on depreciated book value, our estimated economic interest in the venture was approximately 98% . Our economic interest may fluctuate based on a number of factors, including mortgage financing, partnership capital contributions and distributions, and proceeds from gains or losses of asset sales. (3) The negative carrying value is due to the distributions of proceeds from mortgage loans and quarterly distributions of excess cash flow exceeding the original contributions from the partners. Fees we received for various services provided to our unconsolidated joint ventures were recognized in management, leasing and other services as follows (in thousands): Year Ended December 31, 2016 2015 2014 Fees: Development and leasing $ 651 $ 1,827 $ 725 Loan guarantee 452 746 463 Management and marketing 2,744 2,853 2,403 Total Fees $ 3,847 $ 5,426 $ 3,591 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 $3.7 million and $3.9 million as of December 31, 2016 and 2015 , respectively) are amortized over the various useful lives of the related assets. Charlotte In July 2014, we opened an approximately 398,000 square foot outlet center in Charlotte, North Carolina that was developed through, and is owned by, a joint venture formed in May 2013. Construction of the outlet center, which commenced during the third quarter of 2013, was initially funded with equal equity contributions by the partners. In November 2014, the joint venture closed on an interest-only mortgage loan for $90.0 million at an interest rate of LIBOR + 1.45% . The loan initially matures in November 2018, with the option to extend the maturity for one additional year. The joint venture received net loan proceeds of $89.4 million and distributed them equally to the partners. Our partner is providing property management, marketing and leasing services to the joint venture. During construction, we provided development services to the joint venture and joint leasing services with our partner. Columbus In June 2016, we opened an approximately 355,000 square foot outlet center in Columbus, Ohio. As of December 31, 2016 , we and our partner had each contributed $47.5 million to fund development activities. In November 2016, the joint venture closed on an interest-only mortgage loan of $85.0 million at an interest rate of LIBOR + 1.65% . The loan initially matures in November 2019, with two one -year extension options. The joint venture received net loan proceeds of $84.2 million and distributed them equally to the partners. We are providing property management, marketing and leasing services to the joint venture. During construction, our partner provided development services to the joint venture and we, along with our partner, provided joint leasing services. Galveston/Houston In October 2012, we opened an approximately 353,000 square foot outlet center in Texas City, Texas that was developed through, and is owned by, a joint venture formed in June 2011. The development was initially fully funded with equity contributed to the joint venture by Tanger and its partner. In July 2013, the joint venture closed on a $70.0 million mortgage loan with a rate of LIBOR + 1.50% and a maturity date of July 2017, with the option to extend the maturity for one additional year. The joint venture received total loan proceeds of $65.0 million and distributed the net proceeds equally to the partners. We used our share of the proceeds to reduce amounts outstanding under our unsecured lines of credit. We are providing property management, marketing and leasing services to the outlet center. National Harbor In November 2013, we opened an approximately 341,000 square foot outlet center at National Harbor in the Washington, D.C. Metro area that was developed through, and is owned by, a joint venture formed in May 2011. In November 2014, the joint venture amended the initial construction loan to increase the amount available to borrow from $62.0 million to $87.0 million and extended the maturity date until November 2019. The loan carries an interest rate of LIBOR + 1.65% . At the closing of the amendment, the joint venture distributed approximately $19.0 million equally between the partners. The loan balance as of December 31, 2016 was approximately $87.0 million . We are providing property management, marketing and leasing services to the joint venture. RioCan Canada We have a 50 /50 co-ownership agreement with RioCan Real Estate Investment Trust to develop and acquire outlet centers in Canada. Under the agreement, any outlet centers developed or acquired will be branded as Tanger Outlet Centers. We have agreed to provide leasing and marketing services for the outlet centers and RioCan has agreed to provide development and property management services. In October 2014, the co-owners opened Tanger Outlets Ottawa, the first ground up development of a Tanger Outlet Center in Canada. In March 2016, the co-owners opened an approximately 28,000 square foot expansion related to an anchor tenant bringing the total square feet of the outlet center to approximately 316,000 square feet. In 2016, the co-owners commenced construction on a 40,000 square foot expansion, which is expected to open during the second quarter of 2017. In November 2014, the co-owners opened an approximately 149,000 square foot expansion to the existing Cookstown Outlet Mall, bringing the total square feet of the outlet center to approximately 308,000 square feet. Other properties owned by the RioCan Canada co-owners include Les Factoreries Saint-Sauveur and Bromont Outlet Mall. Les Factoreries Saint-Sauveur is approximately 116,000 square feet and the Bromont Outlet Mall is approximately 161,000 square feet. Rental property held and used by our joint ventures are reviewed for impairment in the event that facts and circumstances indicate the carrying amount of an asset may not be recoverable. In such an event, the estimated future undiscounted cash flows associated with the asset is compared to the asset's carrying amount, and if less than such carrying amount, recognize an impairment loss in an amount by which the carrying amount exceeds its fair value. During 2016, the joint venture determined for its Bromont, Quebec outlet center that the estimated future undiscounted cash flows of that property did not exceed the property's carrying value based on the reduction in the property's net operating income. Therefore, the joint venture recorded a $5.8 million non-cash impairment charge in its statement of operations, which equaled the excess of the property's carrying value over its fair value. The fair value was determined using the income approach whereby the joint venture considered the prevailing market income capitalization rates and stabilized net operating income projections. Our share of this impairment charge, $2.9 million , was recorded in equity in earnings of unconsolidated joint ventures in our consolidated statement of operations. Savannah In May 2016, the joint venture expanded the outlet center in Savannah by approximately 42,000 square feet, bringing the outlet center's total gross leasable area to approximately 419,000 square feet. As described in Note 3, we acquired our partners' interest in the Savannah joint venture in August 2016 and have consolidated the property for financial reporting purposes since the acquisition date. Westgate/Glendale As described in Note 3, we acquired our partners' interest in the Westgate joint venture in June 2016 and have consolidated the property for financial reporting purposes since the acquisition date. Wisconsin Dells In February 2015, we sold our equity interest in the joint venture that owned the outlet center located in Wisconsin Dells, Wisconsin for approximately $15.6 million , representing our share of the sales price totaling $27.7 million less our share of the outstanding debt, which totaled $12.1 million . As a result of this transaction, we recorded a gain of approximately $13.7 million in the first quarter of 2015, which represented the difference between the carrying value of our equity method investment and the net proceeds received. Condensed combined summary financial information of joint ventures accounted for using the equity method as of December 31, 2016 and 2015 is as follows (in thousands): Condensed Combined Balance Sheets - Unconsolidated Joint Ventures 2016 2015 Assets Land $ 88,015 $ 103,046 Buildings, improvements and fixtures 503,548 615,662 Construction in progress, including land under development 13,037 62,308 604,600 781,016 Accumulated depreciation (67,431 ) (60,629 ) Total rental property, net 537,169 720,387 Cash and cash equivalents 27,271 28,723 Deferred lease costs, net 13,612 18,399 Prepaids and other assets 12,567 14,455 Total assets $ 590,619 $ 781,964 Liabilities and Owners' Equity Mortgages payable, net $ 335,971 $ 400,935 Accounts payable and other liabilities 20,011 31,805 Total liabilities 355,982 432,740 Owners' equity 234,637 349,224 Total liabilities and owners' equity $ 590,619 $ 781,964 Condensed Combined Statements of Operations- Unconsolidated Joint Ventures: Year Ended December 31, 2016 2015 2014 Revenues $ 106,766 $ 106,042 $ 78,625 Expenses: Property operating 39,576 40,639 30,986 General and administrative 349 571 621 Asset impairment 5,838 — — Abandoned development costs — — 472 Depreciation and amortization 32,930 34,516 23,426 Total expenses 78,693 75,726 55,505 Operating income 28,073 30,316 23,120 Interest expense (8,946 ) (8,674 ) (5,459 ) Other non-operating income 6 19 — Net income $ 19,133 $ 21,661 $ 17,661 The Company and Operating Partnership's share of: Net income $ 10,872 $ 11,484 $ 9,053 Depreciation and asset impairments (real estate related) $ 21,829 $ 20,052 $ 12,212

In April 2016, we entered into four separate interest rate swap agreements, effective April 13, 2016 that fix the base LIBOR rate at an average of 1.03% on notional amounts totaling $175.0 million through January 1, 2021. The derivative financial instruments are comprised of interest rate swaps, which are designated and qualify as cash flow hedges, each with a separate counterparty. We do not use derivatives for trading or speculative purposes and currently do not have any derivatives that are not designated as hedges. The effective portion of changes in the fair value of derivatives designated and qualifying as cash flow hedges is recorded in accumulated other comprehensive loss and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivative, if significant, is recognized directly in earnings. For the year ended December 31, 2016 , the ineffective portion was not significant. The following table represents the effect of the derivative financial instruments on the accompanying consolidated financial statements for the years ended December 31, 2016 , 2015 and 2014 , respectively (in thousands): 2016 2015 2014 Interest Rate Swaps (Effective Portion): Amount of gain (loss) recognized in OCI on derivative $ 4,609 $ (711 ) $ (2,028 )

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 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 December 31, 2016: Asset: Interest rate swaps (prepaids and other assets) $ 3,993 $ — $ 3,993 $ — Total assets $ 3,993 $ — $ 3,993 $ — 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, 2015: Liability: Interest rate swaps (other liabilities) $ (616 ) $ — $ (616 ) $ — Total liabilities $ (616 ) $ — $ (616 ) $ — The estimated fair value and recorded value of our debt as of December 31, 2016 and 2015 were as follows (in thousands): 2016 2015 Level 1 Quoted Prices in Active Markets for Identical Assets or Liabilities $ — $ — Level 2 Significant Observable Inputs 1,137,976 836,361 Level 3 Significant Unobservable Inputs 566,668 779,472 Total fair value of debt $ 1,704,644 $ 1,615,833 Recorded value of debt $ 1,687,866 $ 1,551,924 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.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Noncontrolling interests in the Operating Partnership relate to the interests in the Operating Partnership owned by Non-Company LPs as discussed in Note 2. The noncontrolling interests in other consolidated partnerships consist of outside equity interests in partnerships 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. In 2016 and 2015, adjustments of the noncontrolling interest in the Operating Partnership were made as a result of the changes in the Company's ownership of the Operating Partnership from additional units received in connection with the Company's issuance of common shares upon the exercise of options and grants of share-based compensation awards, and additional units received upon the exchange of Class A common limited partnership units of the Operating Partnership into an equal number of common shares of the Company. As discussed in Note 13, for the years ended December 31, 2016 and 2015 , Non-Company LPs exchanged 24,962 and 25,663 Class A common limited partnership units of the Operating Partnership, respectively, for an equal number of common shares of the Company.

The notional units 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 years ended December 31, 2016 , 2015 , and 2014 , 501,446 , 859,450 and 644,850 units were excluded from the computation, respectively, because these units would not have been issuable if the end of the reporting period were the end of the contingency period. Notional units granted in 2010 were converted into 933,769 restricted common shares in January 2014. The restricted common shares vested on December 31, 2014 and were considered participating securities through the vesting date. 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 years ended December 31, 2016 , 2015 and 2014 , 141,300 , 227,400 and 259,000 options were excluded from the computation, respectively, 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.

Certain of the Company's unvested restricted common share awards contain non-forfeitable rights to distributions or distribution equivalents. The impact of the corresponding unvested restricted unit awards on earnings per unit has been calculated using the two-class method whereby earnings are allocated to the unvested restricted unit awards based on distributions declared and the unvested restricted units' participation rights in undistributed earnings. Unvested restricted common units that do not contain non-forfeitable rights to dividends or dividend equivalents are included in the diluted earnings per unit computation if the effect is dilutive, using the treasury stock method.

Equity-Based Compensation

Equity-Based Compensation	12 Months Ended

Tanger Factory Outlet Centers, Inc [Member]
Equity-Based Compensation	Equity-Based Compensation 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 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 may issue up to 15.4 million common shares under the Plan. Through December 31, 2016 , we had granted 7,543,760 options, net of options forfeited; 5,014,072 restricted common share awards, net of restricted common shares forfeited or withheld for employees' tax obligations; and notional units which may result in the issuance of a maximum of 759,176 common shares. Shares remaining available for future issuance totaled 2,082,992 common shares. The amount and terms of the awards granted under the Plan were determined by the Board of Directors (or the Compensation Committee of the Board of Directors). We recorded equity-based compensation expense in general and administrative expenses in the consolidated statements of operations for the years ended December 31, 2016 , 2015 and 2014 , respectively, as follows (in thousands): 2016 2015 2014 Restricted common shares $ 10,976 $ 11,220 $ 9,978 Notional unit performance awards 3,967 3,030 4,313 Options 376 462 459 Total equity-based compensation $ 15,319 $ 14,712 $ 14,750 Equity-based compensation expense capitalized as a part of rental property and deferred lease costs were as follows (in thousands): 2016 2015 2014 Equity-based compensation expense capitalized $ 985 $ 837 $ 709 As of December 31, 2016 , there was $25.1 million of total unrecognized compensation cost related to unvested common equity-based compensation arrangements granted under the Plan. That cost is expected to be recognized over a weighted-average period of 2.0 years. Restricted Common Share Awards During 2016 , 2015 and 2014 , the Company granted 286,524 , 357,844 and 373,960 restricted common shares, respectively, to the independent directors and the senior executive officers. The independent directors' restricted common shares vest ratably over a three year period and the senior executive officers' restricted common shares vest ratably over a four or five year period. For the restricted shares issued to our chief executive officer during 2016, 2015 and 2014, the restricted share agreements require him to hold the shares for a minimum of three years following each applicable vesting date thereof. Compensation expense related to the amortization of the deferred compensation is being recognized in accordance with the vesting schedule of the restricted shares. For all of the restricted common share awards described above, the grant date fair value of the award was determined based upon the closing market price of the Company's common shares on the day prior to the grant date and the associated compensation expense is being recognized in accordance with the vesting schedule of each grant. The following table summarizes information related to unvested restricted common shares outstanding for the years ended December 31, 2016 , 2015 , and 2014 : Unvested Restricted Common Shares Number of shares Weighted average grant date fair value Outstanding at December 31, 2013 1,057,966 $ 26.91 Granted (1) 1,307,729 26.50 Vested (1,266,245 ) 24.67 Forfeited — — Outstanding at December 31, 2014 1,099,450 $ 29.01 Granted 357,844 36.69 Vested (371,299 ) 28.12 Forfeited — — Outstanding at December 31, 2015 1,085,995 $ 31.84 Granted 286,524 29.64 Vested (388,851 ) 31.30 Forfeited (104,400 ) 34.13 Outstanding at December 31, 2016 879,268 $ 31.09 (1) Includes 933,769 shares granted under the 2010 Multi Year Performance Plan. The total value of restricted common shares vested during the years ended 2016 , 2015 and 2014 was $12.7 million , $13.1 million and $46.6 million , respectively. During 2016 , 2015 and 2014 , we withheld shares with value equivalent to the employees' minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. The total number of shares withheld were 66,760 , 31,863 and 412,239 for 2016 , 2015 and 2014 , respectively, and were 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 $2.2 million , $1.1 million and $15.5 million for 2016 , 2015 and 2014 , respectively, which is reflected as a financing activity within the consolidated statements of cash flows. Notional Unit Performance Awards Outperformance Plan Every year since 2013, the Compensation Committee of Tanger Factory Outlet Centers, Inc. approved the terms of the Tanger Factory Outlet Centers, Inc. Outperformance Plan (the “OPP"). The OPP is a long-term incentive long-term performance based incentive compensation plan. Recipients may earn units which may convert, subject to the achievement of the goals described below, into restricted common shares of the Company based on the Company’s absolute share price appreciation (or total shareholder return) and its share price appreciation relative to its peer group 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 dates (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 OPP performance targets and other relevant information about each plan: 2016 OPP 2015 OPP 2014 OPP (1) 2013 OPP (2) Performance targets (3) Absolute portion of award: Percent of total award 50% 60% 70% 70% Absolute share price appreciation range 18% - 35% 25% - 35% 25% - 35% 25% - 35% Percentage of units to be earned 20%-100% 33%-100% 33%-100% 33%-100% Relative portion of award: Percent of total award 50% 40% 30% 30% Percentile rank of peer group range (4) 40th - 70th 50th - 70th 50th - 70th 50th - 70th Percentage of units to be earned 20%-100% 33%-100% 33%-100% 33%-100% Maximum number of restricted common shares that may be earned 321,900 306,600 329,700 315,150 Grant date fair value per share $ 15.10 $ 15.85 $ 14.71 $ 13.99 (1) On December 31, 2016, the measurement period for the 2014 OPP expired. Based on the Company’s absolute share price appreciation (or total shareholder return) over the three year measurement period, we issued 184,455 restricted common shares in January 2017, with 94,663 vesting immediately and the remaining 89,792 vesting in January 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). Our relative total shareholder return for the 2014 OPP did not meet the minimum share price appreciation and no shares were earned under this component of the 2014 OPP. (2) On December 31, 2015, the measurement period for the 2013 OPP expired and neither of the Company’s absolute nor relative total shareholder returns were sufficient for employees to earn, and therefore become eligible to vest in, any restricted shares under the plan. Accordingly, all 2013 OPP performance awards were automatically forfeited. (3) The performance shares for the OPP will convert on a pro-rata basis by linear interpolation between share price appreciation thresholds, both for absolute share price appreciation and for relative share price appreciation amongst the Company's peer group. The share price targets will be reduced on a dollar-for-dollar basis with respect to any dividend payments made during the measurement period. (4) The peer group is based on companies included in the SNL Equity REIT index. The fair values of the OPP awards granted during the years ended December 31, 2016 , 2015 , and 2014 were determined at the grant dates using a Monte Carlo simulation pricing model and the following assumptions: 2016 2015 2014 Risk free interest rate (1) 1.05 % 0.86 % 0.67 % Expected dividend yield (2) 3.1 % 2.7 % 2.8 % Expected volatility (3) 21 % 20 % 27 % (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) 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. The following table sets forth OPP activity for the years ended December 31, 2016 , 2015 , and 2014 : Unvested OPP Awards (1) Number of units Weighted average grant date fair value Outstanding as of December 31, 2013 315,150 $ 13.99 Awarded 329,700 14.71 Forfeited — — Outstanding as of December 31, 2014 644,850 $ 14.36 Awarded 306,600 15.85 Forfeited (407,150 ) 14.28 Outstanding as of December 31, 2015 544,300 $ 15.26 Awarded 321,900 15.10 Forfeited (107,024 ) 14.77 Outstanding as of December 31, 2016 759,176 $ 15.36 (1) Excludes the 2010 Multi Year Performance Plan that had a four year measurement period. 2010 Multi Year Performance Plan During the first quarter of 2010, the Company's Compensation Committee approved the general terms of the Tanger Factory Outlet Centers, Inc. 2010 Multi-Year Performance Plan, (the "2010 Multi Year Performance Plan"). Under the 2010 Multi-Year Performance Plan, we granted 392,000 notional units, net of notional units forfeited, to award recipients as a group, which would convert into restricted common shares on a one-for one basis, one-for two basis, or one-for- three basis depending upon the amount by which the Company's common shares appreciated above a minimum level over a four year performance period ending December 31, 2013, not to exceed a total value of approximately $32.2 million . Based on the Company's performance over the four year measurement period, we issued 933,769 restricted common shares in January 2014 which vested on December 31, 2014 contingent on continued employment through the vesting date. The fair value of the awards were calculated using a Monte Carlo simulation pricing model. Option Awards In February 2014, the Company granted 282,500 options to non-executive employees of the Company. The exercise price of the options granted during the first quarter of 2014 was $32.02 which equaled the closing market price of the Company's common shares on the day prior to the grant date. The options expire 10 years from the date of grant and 20% of the options become exercisable in each of the first five years commencing one year from the date of grant. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions: expected dividend yield 2.8% ; expected life of 7 years; expected volatility of 32% ; a risk-free rate of 2.46% ; and forfeiture rates of 3.0% to 13.5% dependent upon the employee's position within the Company. Options outstanding at December 31, 2016 had the following weighted average exercise prices and weighted average remaining contractual lives: Options Outstanding Options Exercisable Exercise prices Options Weighted average exercise price Weighted remaining contractual life in years Options Weighted average exercise price $ 26.06 63,200 $ 26.06 4.15 63,200 $ 26.06 32.02 179,000 32.02 7.00 52,400 32.02 242,200 $ 30.46 6.26 115,600 $ 28.76 A summary of option activity under the Plan for the years ended December 31, 2016 , 2015 , and 2014 (aggregate intrinsic value amount in thousands): Options Shares Weighted-average exercise price Weighted-average remaining contractual life in years Aggregate intrinsic value Outstanding as of December 31, 2013 166,300 24.13 Granted 282,500 32.02 Exercised (47,000 ) 19.22 Forfeited (31,300 ) 31.11 Outstanding as of December 31, 2014 370,500 $ 30.20 8.12 $ 2,759 Granted — — Exercised (28,400 ) 27.76 Forfeited (23,700 ) $ 31.58 Outstanding as of December 31, 2015 318,400 $ 30.32 7.19 $ 924 Granted — — Exercised (59,700 ) 29.31 Forfeited (16,500 ) 31.86 Outstanding as of December 31, 2016 242,200 $ 30.46 6.26 $ 1,287 Vested and Expected to Vest as of December 31, 2016 231,064 $ 30.39 6.22 $ 1,245 Exercisable as of December 31, 2016 115,600 $ 28.76 5.44 $ 811 The total intrinsic value of options exercised during the years ended December 31, 2016 , 2015 and 2014 was $469,000 , $200,000 and $724,000 , respectively. 401(k) Retirement Savings Plan We have a 401(k) Retirement Savings Plan covering substantially all employees who meet certain age and employment criteria. An employee may invest pretax earnings in the 401(k) plan up to the maximum legal limits (as defined by Federal regulations). This plan allows participants to defer a portion of their compensation and to receive matching contributions for a portion of the deferred amounts. During the years ended December 31, 2016 , 2015 and 2014 , we contributed approximately $828,000 , $742,000 and $703,000 , respectively, to the 401(k) Retirement Savings Plan.

Summary of Significant Accoun35

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation - The consolidated financial statements of the Company include its accounts and its consolidated subsidiaries, as well as the Operating Partnership and its consolidated subsidiaries. The consolidated financial statements of the Operating Partnership include its accounts and its consolidated subsidiaries. Intercompany balances and transactions have been eliminated in consolidation.
Noncontrolling interests	Noncontrolling interests - In the Company's consolidated financial statements, the “Noncontrolling interests in 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.
Use of Estimates	Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Estimates are used in the calculations of impairment losses, costs capitalized to originate operating leases, costs incurred for the construction and development of properties, and the values of deferred lease costs and other intangibles related to the acquisition of properties. Actual results could differ from those estimates.
Operating Segments	Operating Segments - We focus exclusively on developing, acquiring, owning, operating, and managing outlet shopping centers. We aggregate the financial information of all outlet centers into one reportable operating segment because the outlet centers all have similar economic characteristics and provide similar products and services to similar types and classes of customers
Rental Property	Rental Property - Rental properties are recorded at cost less accumulated depreciation. Buildings, improvements and fixtures consist primarily of permanent buildings and improvements made to land such as infrastructure and costs incurred in providing rental space to tenants. The pre-construction stage of project development involves certain costs to secure land control and zoning and complete other initial tasks essential to the development of the project. These costs are transferred from other assets to construction in progress when the pre-construction tasks are completed. Costs of unsuccessful pre-construction efforts are expensed when the project is no longer probable and, if significant, are recorded as abandoned pre-development costs in the consolidated statement of operations. We also capitalize other costs incurred for the construction and development of properties, including interest, real estate taxes and payroll and related costs associated with employees directly involved. Capitalization of costs commences at the time the development of the property becomes probable and ceases when the property is substantially completed and ready for its intended use. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portion under construction. The amount of payroll and related costs capitalized for the construction and development of properties is based on our estimate of the amount of costs directly related to the construction or development of these assets. Interest costs are capitalized during periods of active construction for qualified expenditures based upon interest rates in place during the construction period until construction is substantially complete. This includes interest incurred on funds invested in or advanced to unconsolidated joint ventures for qualifying development activities until placed in service. Payroll and related costs and interest costs capitalized for the years ended December 31, 2016 , 2015 and 2014 were as follows (in thousands): 2016 2015 2014 Payroll and related costs capitalized $ 2,095 $ 2,989 $ 1,543 Interest costs capitalized $ 2,259 $ 3,448 $ 5,095 Depreciation is computed on the straight-line basis over the estimated useful lives of the assets. We generally use estimated lives of 33 years for buildings and improvements, 15 years for land improvements and 7 years for equipment. Tenant finishing allowances are amortized over the life of the associated lease. Capitalized interest costs are amortized over lives which are consistent with the constructed assets. Expenditures for ordinary maintenance and repairs are charged to operations as incurred while significant renovations and improvements which improve and/or extend the useful life of the asset are capitalized and depreciated over their estimated useful life. Depreciation expense related to rental property included in net income for each of the years ended December 31, 2016 , 2015 and 2014 was as follows (in thousands): 2016 2015 2014 Depreciation expense related to rental property $ 96,813 $ 85,872 $ 80,057 In accordance with accounting guidance for business combinations, we allocate the purchase price of acquisitions based on the fair value of land, building, tenant improvements, debt and deferred lease costs and other intangibles, such as the value of leases with above or below market rents, origination costs associated with the in-place leases, the value of in-place leases and tenant relationships, if any. We depreciate the amount allocated to building, deferred lease costs and other intangible assets over their estimated useful lives, which range up to 33 years. The values of the above and below market leases are amortized and recorded as either an increase (in the case of below market leases) or a decrease (in the case of above market leases) to rental income over the remaining term of the associated lease. The values of below market leases that are considered to have renewal periods with below market rents are amortized over the remaining term of the associated lease plus the renewal periods when the renewal is deemed probable to occur. The value associated with in-place leases is amortized over the remaining lease term and tenant relationships is amortized over the expected term, which includes an estimated probability of the lease renewal. If a tenant terminates its lease prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangibles is written off. The tenant improvements and origination costs are amortized as an expense over the remaining life of the lease (or charged against earnings if the lease is terminated prior to its contractual expiration date). We assess fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. These cash flow projections may be derived from various observable and unobservable inputs and assumptions. Also, we may utilize third-party valuation specialists. As a part of acquisition accounting, the amount by which the fair value of our previously held equity method investment exceeds the carrying book value is recorded as a gain on previously held interest in acquired joint venture. Direct costs to acquire existing outlet centers are expensed as incurred.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash - All highly liquid investments with an original maturity of three months or less at the date of purchase are considered to be cash equivalents. Cash balances at a limited number of banks may periodically exceed insurable amounts. We believe that we mitigate our risk by investing in or through major financial institutions. At December 31, 2016 and 2015 , we had cash equivalent investments in highly liquid money market accounts at major financial institutions of $672,000 and $671,000 , respectively. The restricted cash represents the cash proceeds from property sales that are being held by a qualified intermediary in anticipation of such amounts subsequently being invested in a tax efficient manner under Section 1031 of the Internal Revenue Code of 1986, as amended.
Deferred Charges	The amount of payroll and related costs capitalized is based on our estimate of the time and amount of costs directly related to originating leases. Deferred lease costs and other intangible assets also include the value of leases and origination costs deemed to have been acquired in real estate acquisitions. Deferred Charges - Deferred charges include deferred lease costs and other intangible assets consisting of fees and costs incurred to originate operating leases and are amortized over the expected lease term.
Captive Insurance	Captive Insurance - We have a wholly-owned captive insurance company that is responsible for losses up to certain deductible levels per occurrence for property damage (including wind damage from hurricanes) prior to third-party insurance coverage. Insurance losses are reflected in property operating expenses and include estimates of costs incurred, both reported and unreported.
Impairment of Long-Lived Assets	Impairment of Investments - On a periodic basis, we assess whether there are any indicators that the value of our investments in unconsolidated joint ventures may be impaired. An investment is impaired only if management's estimate of the value of the investment is less than the carrying value of the investments, and such decline in value is deemed to be other than temporary. To the extent impairment has occurred, the loss shall be measured as the excess of the carrying amount of the investment over the value of the investment. Our estimates of value for each joint venture investment are based on a number of assumptions that are subject to economic and market uncertainties including, among others, estimated hold period, terminal capitalization rates, demand for space, competition for tenants, discount and capitalization rates, changes in market rental rates and operating costs of the property. As these factors are difficult to predict and are subject to future events that may alter our assumptions, the values estimated by us in our impairment analysis may not be realized. Impairment of Long-Lived Assets - Rental property held and used by us is reviewed for impairment in the event that facts and circumstances indicate 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 than such carrying amount, recognize an impairment loss in an amount by which the carrying amount exceeds its fair value. Fair value is determined using an income approach whereby we consider the prevailing market income capitalization rates and stabilized net operating income projections. We recognized no impairment losses for our consolidated properties during the years ended December 31, 2016 , 2015 , and 2014 , respectively.
Rental Property Held For Sale	Rental Property Held For Sale - Rental properties designated as held for sale are stated at the lower of their carrying value or their fair value less costs to sell. We classify rental property as held for sale when our Board of Directors approves the sale of the assets and it meets the requirements of current accounting guidance. Subsequent to this classification, no further depreciation is recorded on the assets.
Sales of Real Estate	Sales of Real Estate - For sales transactions meeting the requirements for full profit recognition, the related assets and liabilities are removed from the balance sheet and the resulting gain or loss is recorded in the period the transaction closes. For sales transactions with continuing involvement after the sale, if the continuing involvement with the property is limited by the terms of the sales contract, profit is recognized at the time of sale and is reduced by the maximum exposure to loss related to the nature of the continuing involvement. Sales to entities in which we have or receive an interest are accounted for using partial sale accounting. For transactions that do not meet the criteria for a sale, we evaluate the nature of the continuing involvement, including put and call provisions, if present, and account for the transaction as a financing arrangement, profit-sharing arrangement, leasing arrangement or other alternate method of accounting, rather than as a sale, based on the nature and extent of the continuing involvement. Some transactions may have numerous forms of continuing involvement. In those cases, we determine which method is most appropriate based on the substance of the transaction.
Discontinued Operations	Discontinued Operations - Properties that are sold or classified as held for sale are classified as discontinued operations provided that the disposal represents a strategic shift that has (or will have) a major effect on our operations and financial results (e.g., a disposal of a major geographical area, a major line of business, a major equity method investment or other major parts of an entity).
Derivatives	Derivatives - We selectively enter into interest rate protection agreements to mitigate the impact of changes in interest rates on our variable rate borrowings. The notional amounts of such agreements are used to measure the interest to be paid or received and do not represent the amount of exposure to loss. None of these agreements are used for speculative or trading purposes. We recognize all derivatives as either assets or liabilities in the consolidated balance sheets and measure those instruments at their fair value. We also measure the effectiveness, as defined by the relevant accounting guidance, of all derivatives. We formally document our derivative transactions, including identifying the hedge instruments and hedged items, as well as our risk management objectives and strategies for entering into the hedge transaction. At inception and on a quarterly basis thereafter, we assess the effectiveness of derivatives used to hedge transactions. If a cash flow hedge is deemed effective, we record the change in fair value in other comprehensive income (loss). If after assessment it is determined that a portion of the derivative is ineffective, then that portion of the derivative's change in fair value will be immediately recognized in earnings.
Income Taxes	Income Taxes - We operate in a manner intended to enable the Company to qualify as a REIT under the Internal Revenue Code. A REIT which distributes at least 90% of its taxable income to its shareholders each year and which meets certain other conditions is not taxed on that portion of its taxable income which is distributed to its shareholders. We intend to continue to qualify as a REIT and to distribute substantially all of the Company's taxable income to its shareholders. Accordingly, no provision has been made in the Company's consolidated financial statements for Federal income taxes. As a partnership, the allocated share of income or loss for the year with respect to the Operating Partnership is included in the income tax returns for the partners; accordingly, no provision has been made for Federal income taxes in the Operating Partnership's consolidated financial statements. In addition, we continue to evaluate uncertain tax positions. The tax years 2013 - 2016 remain open to examination by the major tax jurisdictions to which we are subject. With regard to the Company's unconsolidated Canadian joint ventures, deferred tax assets result principally from depreciation deducted under United States Generally Accepted Accounting Principles ("GAAP") that exceed capital cost allowances claimed under Canadian tax rules. A valuation allowance is provided if we believe all or some portion of the deferred tax asset may not be realized. We have determined that a full valuation allowance is required as we believe none of the deferred tax assets will be realized. For income tax purposes, distributions paid to the Company's common shareholders consist of ordinary income, capital gains, return of capital or a combination thereof.
Revenue Recognition	Revenue Recognition - Base rentals are recognized on a straight-line basis over the term of the lease. Straight-line rent adjustments recorded as a receivable in other assets on the consolidated balance sheets were approximately $46.8 million and $40.6 million as of December 31, 2016 and 2015 , respectively. As a provision of a tenant lease, if we make a cash payment to the tenant for purposes other than funding the construction of landlord assets, we defer the amount of such payments as a lease incentive. We amortize lease incentives as a reduction of base rental revenue over the term of the lease. Substantially all leases contain provisions which provide additional rents based on tenants' sales volume (“percentage rentals”) and reimbursement of the tenants' share of advertising and promotion, common area maintenance, insurance and real estate tax expenses. Percentage rentals are recognized when specified targets that trigger the contingent rent are met. Expense reimbursements are recognized in the period the applicable expenses are incurred. For certain tenants, we receive a fixed payment for common area maintenance ("CAM") which is recognized as revenue when earned. When not reimbursed by the fixed-CAM component, CAM expense reimbursements are based on the tenant's proportionate share of the allocable operating expenses for the property. Payments received from the early termination of leases are recognized as revenue from the time the payment is receivable until the tenant vacates the space. The values of the above and below market leases are amortized and recorded as either an increase (in the case of below market leases) or a decrease (in the case of above market leases) to rental income over the remaining term of the associated lease. If a tenant terminates its lease prior to the original contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related above or below market lease value will be written off. We receive development, leasing, loan guarantee, management and marketing fees from third parties and unconsolidated affiliates for services provided to properties held in joint ventures. Development and leasing fees received from unconsolidated affiliates are recognized as revenue when earned to the extent of the third party partners' ownership interest. Development and leasing fees earned to the extent of our ownership interest are recorded as a reduction to our investment in the unconsolidated affiliate. Loan guarantee fees are recognized over the term of the guarantee. Management fees and marketing fees are recognized as revenue when earned. Fees recognized from these activities are shown as management, leasing and other services in our consolidated statements of operations. Fees received from consolidated joint ventures are eliminated in consolidation.
Concentration of Credit Risk	Concentration of Credit Risk - We perform ongoing credit evaluations of our tenants. Although the tenants operate principally in the retail industry, the properties are geographically diverse. No single tenant accounted for 10% or more of combined base and percentage rental income or gross leasable area during 2016 , 2015 or 2014 .
Accounting for Equity-Based Compensation	Accounting for Equity-Based Compensation - We have a shareholder approved equity-based compensation plan, the Incentive Award Plan of Tanger Factory Outlet Centers and Tanger Properties Limited Partnership (Amended and Restated as of April 4, 2014) (the "Plan"), which covers our independent directors, officers and our employees. We may issue non-qualified options and other equity-based awards under the Plan. We account for our equity-based compensation plan under the fair value provisions of the relevant accounting guidance.
Foreign Currency Translation	Foreign Currency Translation - We have entered into a co-ownership agreement with RioCan Real Estate Investment Trust to develop and acquire outlet centers in Canada for which the functional currency is the local currency. The assets and liabilities related to our investments in Canada are translated from their functional currency into U.S. Dollars at the rate of exchange in effect on the balance sheet date. Income statement accounts are translated using the average exchange rate for the period. Our share of unrealized gains and losses resulting from the translation of these financial statements are reflected in equity as a component of accumulated other comprehensive income (loss) in the consolidated balance sheets.
New Accounting Pronouncements	New Accounting Pronouncements - In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-01, Clarifying the Definition of a Business (Topic 805). ASU 2017-01 clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. ASU 2017-01 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted. The update should be applied prospectively. We plan to adopt ASU 2017-01 as of January 1, 2017 and do not expect the adoption to require any additional disclosures. We believe most of our future acquisitions of operating properties will qualify as asset acquisitions and most future transaction costs associated with these acquisitions will be capitalized. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This ASU requires that a statement of cash flows explain the change during the period in cash, cash equivalents, and amounts generally described as restricted cash. Amounts generally described as restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The update should be applied retrospectively to each period presented. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. We plan to adopt this pronouncement for our fiscal year beginning January 1, 2018, and the pronouncement will result in changes to our consolidated statements of cash flows such that restricted cash amounts will be included in the beginning-of-period and end-of-period cash and cash equivalents totals. In October 2016, the FASB issued ASU 2016-17, Interests Held through Related Parties That Are under Common Control. This ASU modifies existing guidance with respect to how a decision maker that holds an indirect interest in a VIE through a common control party determines whether it is the primary beneficiary of the VIE as part of the analysis of whether the VIE would need to be consolidated. Under this ASU, a decision maker would need to consider only its proportionate indirect interest in the VIE held through a common control party. As a result of this ASU, in certain cases, previous consolidation conclusions may change. This ASU is effective for fiscal years beginning after December 15, 2016. Since we have already adopted the amendments in ASU 2015-02 we are required to apply the amendments in this ASU, retrospectively to the beginning of 2016. We do not expect the adoption of ASU 2016-17 to have a material impact on the company's financial position, results of operations or cash flows. In August 2016, the FASB issued ASU No. 2016-15, the Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force), which finalizes Proposed ASU No. EITF-15F of the same name, and addresses stakeholders’ concerns regarding diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. This ASU is effective for fiscal years beginning after December 15, 2017 and for interim periods within those fiscal years, with early adoption permitted. The ASU should be adopted using a retrospective transition approach. We are currently evaluating the impact of adopting the new guidance, but we do not expect the adoption to have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires measurement and recognition of expected versus incurred credit losses for financial assets held. This ASU will be applied on a prospective basis for fiscal years and interim periods beginning after December 15, 2019, with early adoption permitted for fiscal years beginning and interim periods beginning after December 15, 2018. We are currently evaluating the impact of adopting the new guidance, but we do not expect the adoption to have a material impact on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016 including interim periods within that reporting period and may be applied on a modified retrospective basis as a cumulative-effect adjustment to retained earnings as of the date of adoption. Early adoption is permitted. The adoption of this amendment is not expected to have a material impact on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting, this standard eliminates the requirement that when an existing cost method investment qualifies for use of the equity method, an investor must restate its historical financial statements, as if the equity method had been used during all previous periods. Under the new guidance, at the point an investment qualifies for the equity method, any unrealized gain or loss in accumulated other comprehensive income/(loss) ("AOCI") will be recognized through earnings. The standard is effective for interim and annual reporting periods beginning after December 15, 2016, although early adoption is permitted. The adoption of the guidance will be applied prospectively to increases in the level of ownership interest or degree of influence occurring after the new standards effective date. Additional transition disclosures are not required upon adoption. We do not expect that the adoption of this standard will have a material impact on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-06, Derivatives and Hedging (Topic 815) – Contingent Put and Call Options in Debt Instruments (“ASU 2016-06”), which will reduce diversity of practice in identifying embedded derivatives in debt instruments. ASU 2016-06 clarifies that the nature of an exercise contingency is not subject to the “clearly and closely” criteria for purposes of assessing whether the call or put option must be separated from the debt instrument and accounted for separately as a derivative. ASU No. 2016-06 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2016. Entities are required to apply the guidance to existing debt instruments using a modified retrospective transition method as of the period of adoption. We are currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases. ASU 2016-02, codified in ASC 842, amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU 2016-02 will be effective beginning in the first quarter of 2019. Early adoption of ASU 2016-02 as of its issuance is permitted. The new leases standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. Based on a preliminary assessment, we expect our significant operating lease commitments, primarily ground leases, will be required to be recognized as operating lease liabilities and right-of-use assets upon adoption, resulting in an increase in the assets and liabilities on our consolidated balance sheets. We are continuing our evaluation, which may identify additional impacts this standard will have on our consolidated financial statements and related disclosures. In February 2015, FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership and affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. ASU 2015-02 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. During the first quarter of 2016, we adopted ASU No. 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis" and this adoption did not have a material impact on our financial position, results of operations or cash flows. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which requires management to evaluate, at each annual and interim reporting period, whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued and provide related disclosures. This ASU is effective for annual periods ending after December 15, 2016 and interim periods thereafter, early adoption is permitted. We adopted this standard as of December 31, 2016. The adoption of this ASU did not have an impact on our consolidated balance sheets, statements of operations, cash flows or disclosures but may result in more disclosure surrounding the Company's plans for addressing significant upcoming debt maturities. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We are required to adopt the new pronouncement in the first quarter of fiscal 2018 using one of two retrospective application methods. In March, April and May 2016 the FASB issued the following amendments to clarify the implementation guidance: ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing and ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606)—Narrow-Scope Improvements and Practical Expedients. We will adopt ASU 2014-09 effective January 1, 2018. We have identified our revenue streams and are in the process of evaluating the impact on our consolidated financial statements and internal accounting processes; however, as the majority of our revenue is derived from real estate lease contracts we do not expect the adoption of ASU 2014-09 or related amendments and modifications by the FASB will have a material impact on the amount of revenue we recognize in our consolidated financial statements.

Based on the Company’s absolute share price appreciation (or total shareholder return) over the three year measurement period, we issued 184,455 restricted common shares in January 2017, with 94,663 vesting immediately and the remaining 89,792 vesting in January 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). Our relative total shareholder return for the 2014 OPP did not meet the minimum share price appreciation and no shares were earned under this component of the 2014 OPP. (2) On December 31, 2015, the measurement period for the 2013 OPP expired and neither of the Company’s absolute nor relative total shareholder returns were sufficient for employees to earn, and therefore become eligible to vest in, any restricted shares under the plan. Accordingly, all 2013 OPP performance awards were automatically forfeited. (3) The performance shares for the OPP will convert on a pro-rata basis by linear interpolation between share price appreciation thresholds, both for absolute share price appreciation and for relative share price appreciation amongst the Company's peer group. The share price targets will be reduced on a dollar-for-dollar basis with respect to any dividend payments made during the measurement period. (4) The peer group is based on companies included in the SNL Equity REIT index.
Schedule of Share-based Payment Award, Stock Options, Valuation Assumptions	The fair values of the OPP awards granted during the years ended December 31, 2016 , 2015 , and 2014 were determined at the grant dates using a Monte Carlo simulation pricing model and the following assumptions: 2016 2015 2014 Risk free interest rate (1) 1.05 % 0.86 % 0.67 % Expected dividend yield (2) 3.1 % 2.7 % 2.8 % Expected volatility (3) 21 % 20 % 27 % (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) 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.
