	Basis of Presentation
	The unaudited consolidated financial statements included herein have been prepared pursuant to accounting principles generally accepted in the United States of America and should be read in conjunction with the consolidated financial statements and notes thereto of the Company's and the Operating Partnership's combined Annual Report on Form 10-K for the year ended December 31, 2013. The December 31, 2013 balance sheet data in this Form 10-Q was derived from audited financial statements. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the SEC's rules and regulations, although management believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the financial statements for the interim periods have been made. The results of interim periods are not necessarily indicative of the results for a full year.
	Investments in real estate joint ventures that we do not control 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 (loss), cash contributions, distributions and other adjustments required under the equity method of accounting. These investments are evaluated for impairment when necessary. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities. For joint ventures that are determined to be variable interest entities, we consolidate the entity where we are deemed to be the primary beneficiary.
	We evaluate our real estate joint ventures in accordance with the Consolidation guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC"). As a result of our qualitative assessment, we concluded that our Westgate and Savannah joint ventures are Variable Interest Entities ("VIE") and all of our other joint ventures are not a VIE. Westgate and Savannah are each considered a VIE because the voting rights are disproportionate to the economic interests. Investments in real estate joint ventures in which we have a non-controlling ownership interest are accounted for using the equity method of accounting.
	After making the determination that Westgate and Savannah are VIEs, we performed an assessment to determine if we would be considered the primary beneficiary and thus be required to consolidate the balance sheets and results of operations. This assessment was based upon whether we had the following:
	a.	The power to direct the activities of the VIE that most significantly impact the entity's economic performance
	b.	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
	The operating, development, leasing, and management agreements of Westgate and Savannah provide that the activities that most significantly impact the economic performance of the ventures require unanimous consent. Accordingly, we determined that we do not have the power to direct the significant activities that affect the economic performance of the ventures and therefore, have applied the equity method of accounting. Our equity method investment in Westgate was approximately $15.8 million and in Savannah was approximately $20.8 million as of March 31, 2014 . We are unable to estimate our maximum exposure to loss at this time because our guarantees are limited and based on the future operating performance of Westgate and Savannah.
	"Noncontrolling interests in the Operating Partnership" reflects the Non-Company LP's percentage ownership of the Operating Partnership's units. "Noncontrolling interests in other consolidated partnerships" consist of outside equity interests in partnerships 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 their respective ownership interest.

	Tanger Factory Outlet Centers, Inc. and subsidiaries is one of the largest owners and operators of outlet centers in the United States. 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 March 31, 2014, we owned and operated 37 outlet centers, with a total gross leasable area of approximately 11.5 million square feet. We also had partial ownership interests in 7 outlet centers totaling approximately 1.7 million square feet, including 3 outlet centers in Canada.
	Our outlet centers and other assets are held by, and all of our operations are conducted by, Tanger Properties Limited Partnership and subsidiaries. Accordingly, the descriptions of our business, employees and properties are also descriptions of the business, employees and properties of the Operating Partnership. Unless the context indicates otherwise, the term, "Company", refers to Tanger Factory Outlet Centers, Inc. and subsidiaries and the term, "Operating Partnership", refers to Tanger Properties Limited Partnership and subsidiaries. The terms "we", "our" and "us" refer to the Company or the Company and the Operating Partnership together, as the text requires.
	The Company owns the majority of the units of partnership interest issued by the Operating Partnership through its two wholly-owned subsidiaries, Tanger GP Trust and Tanger LP Trust. Tanger GP Trust controls the Operating Partnership as its sole general partner. Tanger LP Trust holds a limited partnership interest. As of March 31, 2014, the Company, through its ownership of Tanger GP Trust and Tanger LP Trust, owned 95,845,714 units of the Operating Partnership and other limited partners (the "Non-Company LPs") collectively owned 5,123,512 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 REIT status. Class B common limited partnership units, which are held by Tanger LP Trust, are not exchangeable for common shares of the Company.

Acquisition of Rental Property	'
	Acquisition of Rental Property
	In October 2003, we and two other owners each having a 33.3% ownership interest, established a joint venture to develop and own a shopping center in Deer Park, New York ("Deer Park"). In August 2013, Deer Park successfully negotiated new financing of the debt obligations for the previous mortgage and mezzanine loans totaling approximately $238.5 million, with a $150.0 million mortgage loan. The new five year mortgage loan bears interest at a 150 basis point spread over LIBOR. The previous mortgage and mezzanine loans were in default, and as part of the refinancing, all default interest associated with the loans was waived. Utilizing funding from our existing unsecured lines of credit, we loaned approximately $89.5 million at a rate of LIBOR plus 3.25% and due on August 30, 2020 to Deer Park representing the remaining amount necessary to repay the previous mortgage and mezzanine loans.
	Subsequent to the debt extinguishment, we acquired an additional one-third interest in the Deer Park property from one of the other owners, bringing our total ownership to a two-thirds interest, for total consideration of approximately $27.9 million, including $13.9 million in cash and 450,576 in Class A common limited partnership units of Tanger Properties Limited Partnership, which are exchangeable for an equivalent number of the Company's common shares. This transaction was accounted for as a business combination resulting in the assets acquired and liabilities assumed being recorded at fair value as a result of the step acquisition. The fair value of the net assets acquired totaled $83.8 million, consisting of $319.4 million in rental property and lease related intangibles, $2.3 million in other identifiable assets and liabilities, and $237.9 million in debt. Upon acquiring an additional one-third interest, we determined, based on the acquisition agreement and other transaction documents which amended our rights with respect to the property and our obligations with respect to the additional one-third interest, that we control the property assets and direct the property’s significant activities and therefore, consolidate the property’s assets and liabilities as of August 30, 2013.
	Following the acquisition, we and the remaining owner restructured certain aspects of our ownership of the property, whereby we receive substantially all of the economics generated by the property and have substantial control over the property's financial activities. Under the new structure, we serve as property manager and control the management, leasing, marketing and other operations of the property. In addition, we and the remaining owner have entered into an agreement whereby they may require us to acquire their ownership interest in the property on the second anniversary of the acquisition date for a price of $28.4 million, and we have the option to acquire their ownership interest on the fourth anniversary of the acquisition date at the same price. Due to the remaining owner's ability to require us to purchase their interest, we have recorded an obligation to redeem their interest at the redemption price as a deferred financing obligation in the other liabilities section of the consolidated balance sheet.

	Investments in Unconsolidated Real Estate Joint Ventures
	Our investments in unconsolidated joint ventures as of March 31, 2014 and December 31, 2013 aggregated $171.0 million and $140.2 million, respectively. We have concluded based on the current facts and circumstances that the equity method of accounting should be used to account for each of the individual joint ventures below. At March 31, 2014 and December 31, 2013, we were members of the following unconsolidated real estate joint ventures:

	-1	Based on capital contribution and distribution provisions in the joint venture agreement, we expect our economic interest in the venture's cash flow to be greater than indicated in the Tanger Share column, which in this case, states our legal interest in this venture. 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.

	Our investments in real estate joint ventures are reduced by the percentage of the profits earned for leasing and development services associated with our ownership interest in each joint venture. Our carrying value of investments in unconsolidated joint ventures differs from our share of the assets reported in the "Summary Balance Sheets - Unconsolidated Joint Ventures" shown below due to adjustments to the book basis, including intercompany profits on sales of services that are capitalized by the unconsolidated joint ventures. The differences in basis (totaling $2.3 million and $1.6 million as of March 31, 2014 and December 31, 2013) are amortized over the various useful lives of the related assets.
	Charlotte, North Carolina
	In May 2013, we formed a 50/50 joint venture for the development of an outlet center in the Charlotte, NC market. Subsequently, during the third quarter of 2013, the joint venture began construction on the outlet center which will be located eight miles southwest of uptown Charlotte at the interchange of I-485 and Steele Creek Road (NC Highway 160), the two major thoroughfares for the city. The approximately 400,000 square foot project will feature approximately 90 brand name and designer stores and is expected to open during the third quarter of 2014.
	As of March 31, 2014, we and our partner had each contributed approximately $20.3 million in cash to the joint venture to fund development activities. We are providing development services to the project; and with our partner, are jointly providing leasing services. Our partner will provide property management and marketing services to the center once open.
	RioCan Canada
	We have entered into a 50/50 co-ownership agreement with RioCan Real Estate Investment Trust ("RioCan Joint Venture") to develop and acquire outlet centers in Canada. Any projects developed or acquired will be branded as Tanger Outlet Centers. We have agreed to provide leasing and marketing services to the venture and RioCan will provide development and property management services.
	In March of 2013, the RioCan Joint Venture acquired the land adjacent to the existing Cookstown Outlet Mall for $13.9 million. The land is being used for an expansion of the Cookstown Outlet Mall which began in May 2013. The expansion, which is expected to open in the fourth quarter of 2014, will add approximately 153,000 square feet and approximately 35 new brand name and designer outlet stores to the center.
	Also, during the second quarter of 2013, the joint venture purchased land for $28.7 million and broke ground on Tanger Outlets Ottawa, the first ground up development of a Tanger Outlet Center in Canada. Located in suburban Kanata off the TransCanada Highway (Highway 417) at Palladium Drive, this center will contain approximately 303,000 square feet and will feature approximately 80 brand name and designer outlet stores. The center is currently expected to open in the fourth quarter of 2014. As of March 31, 2014, we and our co-owner had each contributed $17.2 million in cash to fund development activities on these two projects.
	Savannah, Georgia
	In January 2014, we announced our plans to develop Tanger Outlets Savannah through a joint venture arrangement. The center will include approximately 385,000 square feet. The site is located on I-95, just north of I-16 in Pooler, Georgia, adjacent to the City of Savannah, and near the Savannah International Airport. As of March 31, 2014, our equity contributions totaled $20.9 million and our partner's equity contribution totaled $7.4 million. Contributions we make in excess of $7.4 million will earn a preferred rate of return equal to 8% from the date the contributions are made until the outlet center’s grand opening date, and then 10% annually thereafter.

The unamortized balance of the settled agreements as of March 31, 2014 and December 31, 2013 was approximately $645,000 and $741,000, respectively. As of March 31, 2014, we expect approximately $400,000 of deferred gains on derivative instruments in accumulated other comprehensive income to be reclassified into earnings during the next twelve months.

	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 March 31, 2014:
	Assets:
	Interest rate swaps (prepaids and other assets)	$	1,062	$	—	$	1,062	$	—
	Total assets	$	1,062	$	—	$	1,062	$	—
				Level 1		Level 2		Level 3
				Quoted Prices in Active Markets for Identical Assets or Liabilities		Significant Observable Inputs		Significant Unobservable Inputs

	Total assets	$	1,382	$	—	$	1,382	$	—
	The estimated fair value of our debt, consisting of senior unsecured notes, unsecured term loans, secured mortgages and unsecured lines of credit, at March 31, 2014 and December 31, 2013, was $1.4 billion and $1.4 billion, respectively, and its recorded value was $1.4 billion and $1.3 billion, respectively. Fair values were determined based on level 2 inputs using discounted cash flow analysis with an interest rate or credit spread similar to that of current market borrowing arrangements.
	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.

	Diluted earnings per common share:
	Net income	$	0.15		$	0.16
	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. Notional units granted in 2010 were converted into 933,769 restricted common shares in January 2014. The restricted common shares vest on December 31, 2014 and will be considered participating securities through the vesting date.
	The computation of diluted earnings per share excludes options to purchase common shares when the exercise price is greater than the average market price of the common shares for the period.   For the three months ended March 31, 2014, 279,000 options were excluded from the computation and for the three months ended 2013 no options were excluded from the computation. The assumed exchange of the partnership units held by the Non-Company LPs as of the beginning of the year, which would result in the elimination of earnings allocated to the noncontrolling interest in the Operating Partnership, would have no impact on earnings per share since the allocation of earnings to a common limited partnership unit, as if exchanged, is equivalent to earnings allocated to a common share.
	Certain of the Company's unvested restricted common share awards contain non-forfeitable rights to dividends or dividend equivalents. The impact of these unvested restricted common share awards on earnings per share has been calculated using the two-class method whereby earnings are allocated to the unvested restricted common share awards based on dividends declared and the unvested restricted common shares' participation rights in undistributed earnings. Unvested restricted common shares that do not contain non-forfeitable rights to dividends or dividend equivalents are included in the diluted earnings per share computation if the effect is dilutive, using the treasury stock method.

	Equity Based Compensation of the Company
	We have a shareholder approved equity-based compensation plan, the Amended and Restated Incentive Award Plan of Tanger Factory Outlet Centers and Tanger Properties Limited Partnership (the "Plan"), which covers our independent directors, officers and our employees. For each common share issued by the Company, the Operating Partnership issues one corresponding unit of partnership interest to the Company's wholly owned subsidiaries. Therefore, when the Company grants an equity based award, the Operating Partnership treats each award as having been granted by the Operating Partnership. In the discussion below, the term "we" refers to the Company and the Operating Partnership together and the term "shares" is meant to also include corresponding units of the Operating Partnership.
	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 will vest on December 31, 2014 contingent on continued employment through the vesting date. In accordance with the plan, on December 31, 2013, we paid approximately $3.8 million which represented cumulative dividends that would have been paid to the award recipients had the number of earned common shares been issued at the beginning of the performance period.
	In February 2014, the Company's Board of Directors approved the grant of 282,500 options to non-executive employees of the Company. The exercise price of the options granted during the first quarter of 2014 is $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.
	During February 2014, the Company's Board of Directors approved grants of 373,960 restricted common shares to the Company's independent directors and the Company's senior executive officers. The grant date fair value of the awards ranged from $27.90 to $33.82 per share. The independent directors' restricted common shares vest ratably over a three year period and the senior executive officers' restricted shares vest ratably over a five year period. For the grant to our chief executive officer, the grant has a provision that requires the chief executive officer to hold the shares for a minimum of three years following the vesting date. Compensation expense related to the amortization of the deferred compensation is being recognized in accordance with the vesting schedule of the restricted shares.
	In February 2014, the Compensation Committee of the Company approved the general terms of the Tanger Factory Outlet Centers, Inc. 2014 Outperformance Plan (the “2014 OPP"). The 2014 OPP provides for the grant of performance shares under the Amended and Restated Incentive Award Plan of Tanger Factory Outlet Centers, Inc. The 2014 OPP is a long-term incentive compensation plan pursuant to which award recipients may earn up to an aggregate of 329,700 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 from January 1, 2014 through December 31, 2016.
	We recorded share-based compensation expense in general and administrative expenses in our consolidated statements of operations as follows (in thousands):
		Three months ended
		March 31,
		2014		2013
	Restricted common shares	$	2,306	$	1,889
	Notional unit performance awards	946		528
	Options	114		43
	Total share-based compensation	$	3,366	$	2,460
	Share-based compensation expense capitalized as a part of rental property and deferred lease costs for the three months ended March 31, 2014 and 2013 was $159,000 and $21,000, respectively.

	In April 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (the "Final Standard"). Under the Final Standard, only disposals representing a strategic shift in operations (e.g., a disposal of a major geographic area, a major line of business or a major equity method investment) will be presented as discontinued operations. Under current U.S. GAAP, companies that sell a single investment property are generally required to report the sale as a discontinued operation, which requires the companies to reclassify earnings from continuing operations for all periods presented.
	The Final Standard is effective in the first quarter of 2015 for public entities with calendar year ends. The FASB will permit early adoption of the Final Standard, beginning in the first quarter of 2014, but only for disposals or classifications as held for sale that have not been reported in financial statements previously issued or available for issuance. We are currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements.
