PART I

EXPLANATORY NOTE

This report combines the annual reports on Form 10-K for the year ended December 31, 2019 of Tanger Factory Outlet Centers, Inc. and Tanger Properties Limited 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.

Tanger Factory Outlet Centers, Inc. and subsidiaries is one of the largest owners and operators of outlet centers in the United States and Canada. The Company is a fully-integrated, self-administered and self-managed real estate investment trust ("REIT"), which, through its controlling interest in the Operating Partnership, focuses exclusively on developing, acquiring, owning, operating and managing outlet shopping centers. The outlet centers and other assets are held by, and all of the operations are conducted by, the Operating Partnership. Accordingly, the descriptions of the business, employees and properties of the Company are also descriptions of the business, employees and properties of the Operating Partnership. As the Operating Partnership is the issuer of our registered debt securities, we are required to present a separate set of financial statements for this entity.

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, 2019, the Company, through its ownership of Tanger GP Trust and Tanger LP Trust, owned 92,892,260 units of the Operating Partnership and other limited partners (the "Non-Company LPs") collectively owned 4,911,173 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.

Management operates the Company and the Operating Partnership as one enterprise. The management of the Company consists of the same members as the management of the Operating Partnership. These individuals are officers of the Company and employees of the Operating Partnership. The individuals that comprise the Company's Board of Directors are also the same individuals that make up Tanger GP Trust's Board of Trustees.

We believe combining the annual reports on Form 10-K of the Company and the Operating Partnership into this single report results in the following benefits:

• enhancing investors' understanding of the Company and the Operating Partnership by enabling investors to view the business as a whole in the same manner as management views and operates the business;

• eliminating duplicative disclosure and providing a more streamlined and readable presentation since a substantial portion of the disclosure applies to both the Company and the Operating Partnership; and

• creating time and cost efficiencies through the preparation of one combined report instead of two separate reports.

3

There are only a few differences between the Company and the Operating Partnership, which are reflected in the disclosure in this report. We believe it is important, however, to understand these differences between the Company and the Operating Partnership in the context of how the Company and the Operating Partnership operate as an interrelated consolidated company.

As stated above, the Company is a REIT, whose only material asset is its ownership of partnership interests of the Operating Partnership through its wholly-owned subsidiaries, the Tanger GP Trust and Tanger LP Trust. As a result, the Company does not conduct business itself, other than issuing public equity from time to time and incurring expenses required to operate as a public company. However, all operating expenses incurred by the Company are reimbursed by the Operating Partnership, thus the only material item on the Company's income statement is its equity in the earnings of the Operating Partnership. Therefore, the assets and liabilities and the revenues and expenses of the Company and the Operating Partnership are the same on their respective financial statements, except for immaterial differences related to cash, other assets and accrued liabilities that arise from public company expenses paid by the Company. The Company itself does not hold any indebtedness but does guarantee certain debt of the Operating Partnership, as disclosed in this report.

The Operating Partnership holds all of the outlet centers and other assets, including the ownership interests in consolidated and unconsolidated joint ventures. The Operating Partnership conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for net proceeds from public equity issuances by the Company, which are contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generates the capital required through its operations, its incurrence of indebtedness or through the issuance of partnership units.

Noncontrolling interests, shareholder's equity and partners' capital are the main areas of difference between the consolidated financial statements of the Company and those of the Operating Partnership. The limited partnership interests in the Operating Partnership held by the Non-Company LPs are accounted for as partners' capital in the Operating Partnership's financial statements and as noncontrolling interests in the Company's financial statements.

To help investors understand the significant differences between the Company and the Operating Partnership, this report presents the following separate sections for each of the Company and the Operating Partnership:

• Consolidated financial statements;

• The following notes to the consolidated financial statements:

• Debt of the Company and the Operating Partnership;

• Shareholders' Equity and Partners' Equity;

• Earnings Per Share and Earnings Per Unit;

• Accumulated Other Comprehensive Income of the Company and the Operating Partnership; and

• Liquidity and Capital Resources in the Management's Discussion and Analysis of Financial Condition and Results of Operations.

This report also includes separate Item 9A. Controls and Procedures sections and separate Exhibit 31 and 32 certifications for each of the Company and the Operating Partnership in order to establish that the Chief Executive Officer and the Chief Financial Officer of each entity have made the requisite certifications and that the Company and Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934 and 18 U.S.C. §1350.

The separate sections in this report for the Company and the Operating Partnership specifically refer to the Company and the Operating Partnership. In the sections that combine disclosure of the Company and the Operating Partnership, this report refers to actions or holdings as being actions or holdings of the Company. Although the Operating Partnership is generally the entity that enters into contracts and joint ventures and holds assets and debt, reference to the Company is appropriate because the business is one enterprise and the Company operates the business through the Operating Partnership.

4

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. The separate discussions of the Company and the Operating Partnership in this report should be read in conjunction with each other to understand the results of the Company on a consolidated basis and how management operates the Company.

ITEM 1. BUSINESS

The Company and the Operating Partnership

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 REIT, which focuses exclusively on developing, acquiring, owning, operating and managing outlet shopping centers. As of December 31, 2019, our consolidated portfolio consisted of 32 outlet centers, with a total gross leasable area of approximately 12.0 million square feet, which were 97% occupied and contained over 2,400 stores representing approximately 400 store brands. We also had partial ownership interests in 7 unconsolidated outlet centers totaling approximately 2.2 million square feet, including 3 outlet centers in Canada.

Our outlet centers and other assets are held by, and all of our operations are conducted by, Tanger Properties Limited Partnership and subsidiaries, which we refer to as the Operating Partnership. 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, 2019, the Company, through its ownership of the Tanger GP Trust and Tanger LP Trust, owned 92,892,260 units of the Operating Partnership and the Non-Company LPs collectively owned 4,911,173 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.

Ownership of the Company's common shares is restricted to preserve the Company's status as a REIT for federal income tax purposes. Subject to certain exceptions, a person may not actually or constructively own more than 4% of our common shares. We also operate in a manner intended to enable us to preserve our status as a REIT, including, among other things, making distributions with respect to our then outstanding common shares and preferred shares, if applicable, equal to at least 90% of our taxable income each year.

The Company is a North Carolina corporation that was incorporated in March 1993 and the Operating Partnership is a North Carolina partnership that was formed in May 1993. Our executive offices are currently located at 3200 Northline Avenue, Suite 360, Greensboro, North Carolina, 27408 and our telephone number is (336) 292-3010. Our website can be accessed at www.tangeroutlet.com. Copies of our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments thereto can be obtained, free of charge, on our website as soon as reasonably practicable after we file such material with, or furnish it to, the Securities and Exchange Commission (the "SEC"). The information found on, or otherwise accessible through, our website is not incorporated into, and does not form a part of, this Annual Report on Form 10-K or any other report or document we file with or furnish to the SEC.

Recent Developments

Dispositions of Consolidated Outlet Centers

During March 2019, we closed on the sale of four non-core consolidated outlet centers for total gross proceeds of $130.5 million, and total net proceeds of approximately $128.2 million, which resulted in a gain on sale of assets of $43.4 million. The four properties were located in Nags Head, North Carolina; Ocean City, Maryland; Park City, Utah; and Williamsburg, Iowa and represented 6.8% of the Company’s consolidated portfolio square footage. The proceeds from the sale of these unencumbered assets were used to pay down balances outstanding under our unsecured lines of credit.

Share Repurchase Program

In February 2019, the Company’s Board of Directors authorized the repurchase of an additional $44.3 million of our outstanding common shares for an aggregate authorization of $169.3 million until May 2021. The remaining amount authorized to be repurchased under the program as of December 31, 2019 was approximately $80.0 million.

The Outlet Concept

Outlet centers generally consist of stores operated by manufacturers and brand name retailers that sell primarily first quality, branded products, some of which are made specifically for the outlet distribution channel, to consumers at significant discounts from regular retail prices charged by department stores and specialty stores. Outlet centers offer advantages to manufacturers and brand name retailers as they are often able to charge customers lower prices for brand name and designer products by eliminating the third party retailer. Outlet centers also typically have lower operating costs than other retailing formats, enhancing their profit potential. Outlet centers enable retailers to optimize the size of production runs while continuing to maintain control of their distribution channels. Outlet centers also enable manufacturers and brand name retailers to establish a direct relationship with their customers.

We believe that outlet centers present an attractive opportunity for capital investment as many retailers view the outlet concept as a profitable distribution channel. However, due to present economic conditions, the availability of multiple retail channels, and the potential for increased competition from other outlet center developers, new developments or expansions may not provide an initial return on investment as high as has been historically achieved and there may not be as many opportunities to develop or expand.

Our Outlet Centers

Each of our outlet centers, except one joint venture property, carries the Tanger brand name. We believe that our tenants and consumers recognize the Tanger brand as one that provides outlet shopping centers where consumers can trust the brand, quality and price of the merchandise they purchase directly from the manufacturers and brand name retailers.

As one of the original participants in this industry, we have established long-standing relationships with many of our tenants that we believe is critical in developing and operating successful outlet centers.

Our consolidated outlet centers range in size from 104,009 to 739,110 square feet and are typically located at least 10 miles from major department stores and manufacturer-owned, full-price retail stores. Historically, manufacturers prefer these locations so that they do not compete directly with their major customers and their own stores. Many of our outlet centers are located near tourist destinations to attract tourists who consider shopping to be a recreational activity. Additionally, our centers are often situated in close proximity to interstate highways that provide accessibility and visibility to potential customers.

We have a diverse tenant base throughout our consolidated portfolio, comprised of approximately 400 manufacturers, brand name and discount apparel and home retailers such as American Eagle Outfitters, Banana Republic Factory Store, Calvin Klein, Coach, Gap Outlet, Hugo Boss Factory Store, Kate Spade New York, Lululemon Athletica, Nike Factory Store, North Face, Saks Fifth Avenue Off 5th, T.J. Maxx, Tory Burch, Under Armour, Vineyard Vines, West Elm Outlet, Williams-Sonoma Outlet, and many more.

6

No single tenant, including all of its store concepts, accounted for 10% or more of our combined base and percentage rental revenues during 2019, 2018 or 2017. As of December 31, 2019, no single tenant accounted for more than 8% of our leasable square feet or 7% of our combined base and percentage rental revenues.

A portion of our rental revenues are dependent on variable revenue sources. For the year ended December 31, 2019, the components of rental revenues are as follows (in thousands):

	2019
Rental revenues - fixed	$	360,513
Rental revenues - variable (1)	103,433
Rental revenues	$	463,946

(1) Primarily includes rents based on a percentage of tenant sales volume and reimbursable expenses such as common area expenses, utilities, insurance and real estate taxes.

Business History

Stanley K. Tanger, the Company's founder, entered the outlet center business in 1981. Prior to founding our company, Stanley K. Tanger and his son, Steven B. Tanger, our Chief Executive Officer, built and managed a successful family owned apparel manufacturing business, Tanger/Creighton, Inc., which included the operation of five outlet stores. Based on their knowledge of the apparel and retail industries, as well as their experience operating Tanger/Creighton, Inc.'s outlet stores, they recognized that there would be a demand for outlet centers where a number of manufacturers could operate in a single location and attract a large number of shoppers.

Steven B. Tanger joined the predecessor company in 1986, and by June 1993, the Tangers had developed 17 outlet centers totaling approximately 1.5 million square feet. In June 1993, we completed our initial public offering, making Tanger Factory Outlet Centers, Inc. the first publicly traded outlet center company. Since our initial public offering, we have grown our portfolio through the strategic development, expansion and acquisition of outlet centers and are now one of the largest owner operators of outlet centers in the United States and Canada.

Business Strategy

Our company has been built on a firm foundation of strong and enduring business relationships coupled with conservative business practices. We partner with many of the world's best known and most respected retailers and manufacturers. By fostering and maintaining strong tenant relationships with these successful, high volume companies, we have been able to solidify our position as a leader in the outlet industry for well over a quarter century. The confidence and trust that we have developed with our retail partners from the very beginning has allowed us to forge the impressive retail alliances that we enjoy today with our brand name retailers and manufacturers. Our seasoned team of real estate professionals utilize the knowledge and experience that we have gained to give us a competitive advantage in the outlet business.

As of December 31, 2019, our consolidated outlet centers were 97% occupied with average tenant sales of $395 per square foot. Our portfolio of properties has had an average occupancy rate of 95% or greater on December 31st of each year since the predecessor company was founded in 1981. We believe our ability to achieve this level of performance is a testament to our long-standing tenant relationships, industry experience and our expertise in the development, leasing and operation of outlet centers.

7

Growth Strategy

Our goal is to build shareholder value through a comprehensive, conservative plan for sustained, long-term growth. We focus our efforts on increasing rents in our existing outlet centers, renovating and expanding selected outlet centers and reaching new markets through ground-up developments or acquisitions of existing outlet centers. While we expect new development to continue to be important to the growth of our portfolio in the long-term. However, the number of new development opportunities may be limited or completed at a slower pace than historically given the current disruption in the retail environment caused in part by Internet competition and numerous store closings as a result of bankruptcy filings or brand wide restructuring of certain retailers. Future outlet centers may be wholly-owned by us or developed through joint venture arrangements.

Increasing rents at existing outlet centers

Our leasing team focuses on the marketing of available space to maintain our standard for high occupancy levels. The majority of our leases are negotiated to provide for inflation-based contractual rent increases or periodic fixed contractual rent increases and percentage rents. We have historically been able to renew many leases at higher base rents per square-foot and replace underperforming tenants with new or existing tenants in our portfolio. Given the current retail environment as discussed above, we may choose to renew certain tenants or execute leases with new tenants at lower rental rates to maintain a high portfolio occupancy rate.

Developing new outlet centers

We believe that there continue to be opportunities to introduce the Tanger brand in untapped or under-served markets across the United States and Canada in the long-term. We believe our 39 years of outlet industry experience, extensive development expertise and strong retail relationships give us a distinct competitive advantage.

In order to identify new markets across North America, we follow a general set of guidelines when evaluating opportunities for the development of new outlet centers. This typically includes seeking locations within markets that have at least one million people residing within a 30 to 40 mile radius with an average household income of at least $65,000 per year, frontage on a major interstate or roadway that has excellent visibility and a traffic count of at least 55,000 cars per day. Leading tourist, vacation and resort markets that receive at least five million visitors annually are also closely evaluated. Although our current goal is to target sites that are large enough to support outlet centers with approximately 60 to 90 stores totaling at least 250,000 to 350,000 square feet, we maintain the flexibility to vary our minimum requirements based on the unique characteristics of a site, tenant demand and our prospects for future growth and success.

In order to help ensure the viability of proceeding with a project, we gauge the interest of our retail partners first. We typically prefer to have signed leases or leases out for negotiation with tenants for at least 60% of the space in each outlet center prior to acquiring the site and beginning construction; however, we may choose to proceed with construction with less than 60% of the space pre-leased under certain circumstances. Construction of a new outlet center has typically taken us nine to twelve months from groundbreaking to grand opening of the outlet center.

Expanding and renovating existing outlet centers

Keeping our outlet shopping centers vibrant and growing is a key part of our formula for success. In order to maintain our reputation as the premiere outlet shopping destination in the markets that we serve, we have an ongoing program of renovations and expansions taking place at our outlet centers. Construction for expansion and renovation to existing properties typically takes less time, usually between six to nine months depending on the scope of the project.

Acquiring outlet centers

We may selectively choose to acquire individual properties or portfolios of properties that meet our strategic investment criteria. We believe that our extensive experience in the outlet center business, access to capital markets, familiarity with real estate markets and our management experience will allow us to evaluate and execute our acquisition strategy successfully over time. Through our tenant relationships, our leasing professionals have the ability to implement a re-merchandising strategy when needed to increase occupancy rates and value. We believe that our managerial skills, marketing expertise and overall outlet industry experience will also allow us to add long-term value and viability to these outlet centers.

8

Operating Strategy

Increasing cash flow to enhance the value of our properties and operations remains a primary business objective. Through targeted marketing and operational efficiencies, we strive to improve sales and profitability of our tenants and our outlet centers as a whole. Achieving higher base and percentage rents and generating additional income from temporary leasing, vending and other sources also remains an important focus and goal.

Leasing

Our long-standing retailer relationships and our focus on identifying emerging retailers allow us the ability to provide our shoppers with a collection of the world's most popular outlet stores. Tanger customers shop and save on their favorite brand name merchandise including men's, women's and children's ready-to-wear, lifestyle apparel, footwear, jewelry and accessories, tableware, housewares, luggage and home goods. In order for our outlet centers to perform at a high level, our leasing professionals continually monitor and evaluate tenant mix, store size, store location and sales performance. They also work to assist our tenants through re-sizing and re-location of retail space within each of our outlet centers for maximum sales of each retail unit across our portfolio.

Marketing

Our marketing plans deliver compelling, well-crafted messages and enticing promotions and events to targeted audiences. Our plans are based on a basic measure of success - increase sales and traffic for our retail partners and we will create successful outlet centers. Utilizing a strategic mix of print, radio, television, direct mail, our consumer website, Internet advertising, social networks, mobile applications and public relations, we consistently reinforce the Tanger brand. Our marketing efforts are also designed to build loyalty with current Tanger shoppers and create awareness with potential customers. The majority of consumer-marketing expenses incurred by us are reimbursable by our tenants.

Capital Strategy

We believe we achieve a strong and flexible financial position by attempting to: (1) maintain a conservative leverage position relative to our portfolio when pursuing new development, expansion and acquisition opportunities, (2) extend and sequence debt maturities, (3) manage our interest rate risk through a proper mix of fixed and variable rate debt, (4) maintain access to liquidity by using our lines of credit in a conservative manner and (5) preserve internally generated sources of capital by strategically divesting of our non-core assets and maintaining a conservative distribution payout ratio. We manage our capital structure to reflect a long-term investment approach and utilize multiple sources of capital to meet our requirements.

We intend to retain the ability to raise additional capital, including public debt or equity, to pursue attractive investment opportunities that may arise and to otherwise act in a manner that we believe to be in the best interests of our shareholders and unitholders. We are a well-known seasoned issuer with a shelf registration statement on Form S-3 that allows us to register unspecified amounts of different classes of securities. To generate capital to reinvest into other attractive investment opportunities, we may also consider the use of additional operational and developmental joint ventures, the sale or lease of outparcels on our existing properties and the sale of certain properties that do not meet our long-term investment criteria. Based on cash provided by operations, existing lines of credit, ongoing relationships with certain financial institutions and our ability to issue debt or equity subject to market conditions, we believe that we have access to the necessary financing to fund our planned capital expenditures during 2020.

We anticipate that adequate cash will be available to fund our operating and administrative expenses, regular debt service obligations, and the payment of dividends in accordance with REIT requirements in both the short and long-term. Although we receive most of our rental payments on a monthly basis, distributions to shareholders and unitholders are made quarterly and interest payments on the senior, unsecured notes are made semi-annually. Amounts accumulated for such payments will be used in the interim to reduce the outstanding borrowings under our existing lines of credit or invested in short-term money market or other suitable instruments adhering to our investment policies.

9

We believe our current balance sheet position is financially sound; however, due to the uncertainty and unpredictability of the capital and credit markets, we can give no assurance that affordable access to capital will exist between now and when our next significant debt maturity, which is our unsecured lines of credit. The unsecured lines of credit expire in 2021, with a one-year extension option that may extend the maturity to 2022. As a result, our current primary focus is to continually strengthen our capital and liquidity position by controlling and reducing construction and overhead costs, generating positive cash flows from operations to cover our distributions and reducing outstanding debt.

Competition

We carefully consider the degree of existing and planned competition in a proposed area before deciding to develop, acquire or expand a new outlet center. Our outlet centers compete for customers primarily with outlet centers built and operated by different developers, traditional shopping malls, full- and off-price retailers and e-commerce retailers. We believe that the majority of our customers visit outlet centers because they are intent on buying name-brand products at discounted prices. Traditional full-and off-price retailers and e-commerce retailers are often unable to provide such a variety and depth of name-brand products at attractive prices.

Because our revenues are ultimately linked to our tenants' success, we are affected by the same competitive factors, such as consumer spending habits and on-line shopping, as our tenants. Tenants of outlet centers are generally adverse to direct competition with major brick and mortar retailers and their own specialty stores. For this reason, our outlet centers generally compete only to a limited extent with traditional malls in or near metropolitan areas as our centers are typically located at least 10 miles from major department stores and manufacturer-owned, full-price retail stores. In recent years, some of our tenants have been adversely impacted by changes in consumer spending habits and the convenience of on-line shopping.

We compete with institutional pension funds, private equity investors, other REITs, individual owners of outlet centers, specialty stores and others who are engaged in the acquisition, development or ownership of outlet centers and stores. In addition, the number of entities competing to acquire or develop outlet centers has increased and may continue to increase in the future, which could increase demand for these outlet centers and the prices we must pay to acquire or develop them. Nevertheless, we believe the high barriers to entry in the outlet industry, including the need for extensive marketing programs to drive traffic to the centers and relationships with premier manufacturers and brand name retailers, will continue to limit the number of new outlet centers developed each year.

Financial Information

We have one reportable operating segment. For financial information regarding our segment, see our consolidated financial statements.

Corporate and Regional Headquarters

We rent space in an office building in Greensboro, North Carolina where our corporate headquarters is located as well as a regional office in Miami, Florida.

As of February 1, 2020, we maintain offices and employ on-site management at 34 consolidated and unconsolidated outlet centers. The managers closely monitor the operation, marketing and local relationships at each of their outlet centers.

10

Insurance

We believe that as a whole our properties are covered by adequate comprehensive liability, fire, flood, earthquake and extended loss insurance provided by reputable companies with commercially reasonable and customary deductibles and limits. Northline Indemnity, LLC, ("Northline"), a wholly-owned captive insurance subsidiary of the Operating Partnership, is responsible for losses up to certain levels for property damage (including wind damage from hurricanes) prior to third-party insurance coverage. Specified types and amounts of insurance are required to be carried by each tenant under their lease. There are however, types of losses, like those resulting from wars or nuclear radiation, which may either be uninsurable or not economically insurable in some or all of our locations. An uninsured loss could result in a loss to us of both our capital investment and anticipated profits from the affected property.

Employees

As of February 1, 2020, we had 285 full-time employees, located at our corporate headquarters in North Carolina, our regional office in Miami and 34 business offices. At that date, we also employed 351 part-time employees at various locations.

ITEM 1A.RISK FACTORS

Risks Related to Real Estate Investments

We may be unable to develop new outlet centers or expand existing outlet centers successfully.

We intend to continue to develop new outlet centers and expand existing outlet centers as opportunities arise. However, there are significant risks associated with our development activities in addition to those generally associated with the ownership and operation of established retail properties. While we have policies in place designed to limit the risks associated with development, these policies do not mitigate all development risks associated with a project. These risks include the following:

• significant expenditure of money and time on projects that may be delayed or never be completed;

• higher than projected construction costs;

• shortage of construction materials and supplies;

• failure to obtain zoning, occupancy or other governmental approvals or to the extent required, tenant approvals; and

• late completion because of construction delays, delays in the receipt of zoning, occupancy and other approvals or other factors outside of our control.

Any or all of these factors may impede our development strategy and adversely affect our overall business.

The economic performance and the market value of our outlet centers are dependent on risks associated with real property investments.

Real property investments are subject to varying degrees of risk. The economic performance and values of real estate may be affected by many factors, including changes in the national, regional and local economic climate, inflation, changes in government policies and regulations, unemployment rates, consumer confidence, consumer shopping preferences, local conditions such as an oversupply of space or a reduction in demand for real estate in the area, the attractiveness of the properties to tenants, competition from other available space, our ability to provide adequate maintenance and insurance and increased operating costs.

11

Real property investments are relatively illiquid.

Our outlet centers represent a substantial portion of our total consolidated assets. These assets are relatively illiquid. As a result, our ability to sell one or more of our outlet centers in response to any changes in economic or other conditions is limited. If we want to sell an outlet center, there can be no assurance that we will be able to dispose of it in the desired time period or that the sales price will exceed the cost of our investment.

Properties have been in the past and may be in the future subject to impairment charges which can adversely affect our financial results.

We periodically evaluate long-lived assets to determine if there has been any impairment in their carrying values and record impairment losses if the undiscounted cash flows estimated to be generated by those assets are less than their carrying amounts or if there are other indicators of impairment.  If it is determined that an impairment has occurred, we would be required to record an impairment charge equal to the excess of the asset's carrying value over its estimated fair value, which could have a material adverse effect on our financial results in the accounting period in which the adjustment is made.  Our estimates of undiscounted cash flows expected to be generated by each property are based on a number of assumptions that are subject to economic and market uncertainties including, but not limited to, estimated hold period, terminal capitalization rates, demand for space, competition for tenants, changes in market rental rates and costs to operate each property. As these factors are difficult to predict and are subject to future events that may alter our assumptions, the future cash flows estimated in our impairment analysis may not be achieved.

Also, 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 is measured as the excess of the carrying amount of the investment over the estimated fair 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.

In recent years, we have recorded impairment charges related to both our long-lived assets and our investments in consolidated joint ventures. In addition, based upon current market conditions, one of our outlet centers has an estimated fair value significantly less than its recorded carrying value of approximately $100.0 million. However, based on our current plan with respect to that outlet center, we believe that its carrying amount is recoverable and therefore no impairment charge was recorded. Accordingly, we will continue to monitor circumstances and events in future periods that could affect inputs such as the expected holding period, operating cash flow forecasts and capitalization rates, utilized to determine whether an impairment charge is necessary.  As these inputs are difficult to predict and are subject to future events that may alter our assumptions, the future cash flows estimated by management in its impairment analysis may not be achieved, and actual losses or impairment may be realized in the future.

Dispositions may not achieve anticipated results.

From time to time, we have strategically disposed of assets, and may dispose of additional assets in the future, with the goal of improving the overall performance of our core portfolio. However, we may not achieve the results we originally anticipated at the time of disposition. If we are not successful at achieving the anticipated results, there is a potential for a significant adverse impact on our returns and our overall profitability.

12

We face competition for the acquisition and development of outlet centers, and we may not be able to complete acquisitions or developments that we have identified.

We intend to grow our business in part through acquisitions and new developments. We compete with institutional pension funds, private equity investors, other REITs, small owners of outlet centers, specialty stores and others who are engaged in the acquisition, development or ownership of outlet centers and stores. These competitors may succeed in acquiring or developing outlet centers themselves. Also, our potential acquisition targets may find our competitors to be more attractive acquirers because they may have greater marketing and financial resources, may be willing to pay more, or may have a more compatible operating philosophy. In addition, the number of entities competing to acquire or develop outlet centers has increased and may continue to increase in the future, which could increase demand for these outlet centers and the prices we must pay to acquire or develop them. If we pay higher prices for outlet centers, our profitability may be reduced. Also, once we have identified potential acquisitions, such acquisitions are subject to the successful completion of due diligence, the negotiation of definitive agreements and the satisfaction of customary closing conditions. We cannot assure you that we will be able to reach acceptable terms with the sellers or that these conditions will be satisfied.

We may be subject to environmental regulation.

Under various federal, state and local laws, ordinances and regulations, we may be considered an owner or operator of real property and may be responsible for paying for the disposal or treatment of hazardous or toxic substances released on or in our property or disposed of by us, as well as certain other potential costs which could relate to hazardous or toxic substances (including governmental fines and injuries to persons and property). This liability may be imposed whether or not we knew about, or were responsible for, the presence of hazardous or toxic substances.

Possible terrorist activity, other acts or threats of violence, public health crises and threats to public safety could adversely affect our financial condition and results of operations.

Terrorist attacks and threats of terrorist attacks, whether in the United States, Canada or elsewhere, or other acts or threats of violence may result in declining economic activity, which could harm the demand for goods and services offered by our tenants and the value of our properties and might adversely affect the value of an investment in our securities. Similarly, public health crises may negatively impact consumer spending. Such a resulting decrease in retail demand could make it difficult for us to renew or re-lease our properties and may adversely impact our results of operations to the extent our revenues are dependent on variable revenue sources.

Terrorist activities or violence also could directly affect the value of our properties through damage, destruction or loss. In addition, these acts and threats might erode business and consumer confidence and spending, and might result in increased volatility in national and international financial markets and economies. Any one of these events might decrease demand for real estate, decrease or delay the occupancy of our properties, impair the ability of tenants to meet their obligations under their existing leases, limit our access to capital, increase our cost of raising capital and/or give rise to third party claims.

Risks Related to our Business

Our earnings and therefore our profitability are dependent on rental income from real property.

Substantially all of our income is derived from rental income from real property. Our income and funds for distribution would be adversely affected if rental rates at our centers decrease, if a significant number of our tenants were unable to meet their obligations to us or if we were unable to lease a significant amount of space in our outlet centers on economically favorable lease terms. In addition, the terms of outlet store tenant leases traditionally have been significantly shorter than in other retail segments. There can be no assurance that any tenant whose lease expires in the future will renew such lease or that we will be able to re-lease space on economically favorable terms.

13

We are substantially dependent on the results of operations of our retail tenants and their bankruptcy, early termination or closing could adversely affect us.

Our operations are subject to the results of operations of our retail tenants. A portion of our rental revenues are derived from percentage rents that directly depend on the sales volume of certain tenants. Accordingly, declines in these tenants' results of operations would reduce the income produced by our properties. If the sales or profitability of our retail tenants decline sufficiently, whether due to a change in consumer preferences, legislative changes that increase the cost of their operations or otherwise, such tenants may be unable to pay their existing rents as such rents would represent a higher percentage of their sales. Any resulting leasing delays, failures to make payments or tenant bankruptcies could result in the termination of such tenants' leases.

A number of companies in the retail industry, including some of our tenants, have declared bankruptcy or have voluntarily closed all or certain of their stores in recent years. The bankruptcy of a major tenant or number of tenants may result in the closing of certain affected stores or reduction of rent for stores that remain operating. For example, in 2018 and 2019, our revenues were adversely affected by bankruptcy filings and other tenant closures during those periods. We expect other store closings to impact our operating results in 2020. In addition, certain of our lease agreements include co-tenancy and/or sales-based provisions that may allow a tenant to pay reduced rent and/or terminate a lease prior to its natural expiration if we fail to maintain certain occupancy levels or retain specified named tenants, or if the tenant does not achieve certain specified sales targets.

Re-leasing this space may take longer than our historical experience. In addition, we may be unable to replace the space at equal or greater rent, and/or we may incur significant tenant allowances to induce tenants to enter into leases. As such, the closings of a significant amount of stores could have a material adverse effect on our results of operations and could result in a lower level of funds for distribution.

Certain of our properties are subject to ownership interests held by third parties, whose interests may conflict with ours and thereby constrain us from taking actions concerning these properties which otherwise would be in our best interests and our shareholders' interests.

We own partial interests in outlet centers with various joint venture partners. The approval or consent of the other members of these joint ventures is required before we may sell, finance, expand or make other significant changes in the operations of these properties. We also may not have control over certain major decisions, including approval of the annual operating budgets, selection or termination of the property management company, leasing and the timing and amount of distributions, which could result in decisions that do not fully reflect our interests. To the extent such approvals or consents are required, we may experience difficulty in, or may be prevented from, implementing our plans and strategies with respect to expansion, development, property management, on-going operations, financing (for example, decisions as to whether to refinance or obtain financing, when and whether to pay down principal of any loan and whether and how to cure any defaults under loan documents) or other similar transactions with respect to such properties.

We face risks associated with climate change.

To the extent climate change causes changes in weather patterns, our properties in certain markets could experience, among other impacts, increases in storm intensity, rising sea levels and other natural disasters. Over time, these conditions could result in volatile or decreased demand for retail space at certain of our properties or, in extreme cases, our inability to operate the properties at all. Climate change may also have indirect effects on our business by increasing the cost of (or making unavailable) insurance on favorable terms, or at all, increasing the cost of energy at our properties or requiring us to spend funds to repair and protect our properties against such risks. Moreover, compliance with new laws or regulations related to climate change, including compliance with “green” building codes, may require us to make improvements to our existing properties or increase taxes and fees assessed on us or our properties.

14

An uninsured loss or a loss that exceeds our insurance policies on our outlet centers or the insurance policies of our tenants could subject us to lost capital and revenue on those outlet centers.

Some of the risks to which our outlet centers are subject, including risks of terrorist attacks, war, earthquakes, hurricanes and other natural disasters, are not insurable or may not be insurable in the future. Should a loss occur that is uninsured or in an amount exceeding the combined aggregate limits for the insurance policies noted above or in the event of a loss that is subject to a substantial deductible under an insurance policy, we could lose all or part of our capital invested in and anticipated revenue from one or more of our outlet centers, which could adversely affect our results of operations and financial condition, as well as our ability to make distributions to our shareholders.

Under the terms and conditions of our leases, tenants generally are required to indemnify and hold us harmless from liabilities resulting from injury to persons and contamination of air, water, land or property, on or off the premises, due to activities conducted in the leased space, except for claims arising from negligence or intentional misconduct by us or our agents. Additionally, tenants generally are required, at the tenant's expense, to obtain and keep in full force during the term of the lease, liability and property damage insurance policies issued by companies acceptable to us. These policies include liability coverage for bodily injury and property damage arising out of the ownership, use, occupancy or maintenance of the leased space. All of these policies may involve substantial deductibles and certain exclusions. Therefore, an uninsured loss or loss that exceeds the insurance policies of our tenants could also subject us to lost capital and revenue.

Consumer spending habits have changed and may continue to evolve.

Certain retailers have experienced, and may continue to experience for the foreseeable future considerable decreases in customer traffic in their retail stores, increased competition from alternative retail options such as those accessible via the Internet and other forms of pressure on their business models. As pressure on such retailers increases, their ability to maintain their stores, meet their obligations both to us and to their external lenders and suppliers, withstand takeover attempts by investors or rivals or avoid bankruptcy and/or liquidation may be impaired, adversely impacting our results of operations to the extent our revenues are dependent on variable revenue sources, and resulting in closures of their stores or their seeking a lease modification with us. Any lease renewal or modification could be unfavorable to us as the lessor and could decrease rents or expense recovery charges.

Our Canadian investments may subject us to different or greater risk from those associated with our domestic operations.

As of December 31, 2019, through a co-ownership arrangement with a Canadian REIT, we have an ownership interest in three properties in Canada.  Our operating results and the value of our Canadian operations may be impacted by any unhedged movements in the Canadian dollar. Canadian ownership activities carry risks that are different from those we face with our domestic properties. These risks include:

• adverse effects of changes in the exchange rate between the U.S. and Canadian dollar;

• changes in Canadian political and economic environments, regionally, nationally, and locally;

• challenges of complying with a wide variety of foreign laws;

• changes in applicable laws and regulations in the United States that affect foreign operations;

• property management services being provided directly by our 50/50 ​co-owner, not by us; and

• obstacles to the repatriation of earnings and cash.

Any or all of these factors may adversely impact our operations and financial results, as well as our overall business.

15

Our success significantly depends on our key personnel and our ability to attract and retain key personnel.

Our success depends upon the personal efforts and abilities of our senior management team and other key personnel. Although we believe we have a strong management team with relevant industry expertise, the extended loss of the services of key personnel could have a material adverse effect on the securities markets' view of our prospects and materially harm our business. Also, our success and the achievement of our goals are dependent upon our ability to attract and retain qualified employees.

Risks Related to our Indebtedness and Financial Markets

We are subject to the risks associated with debt financing.

We are subject to the risks associated with debt financing, including the risk that the cash provided by our operating activities will be insufficient to meet required payments of principal and interest. Disruptions in the capital and credit markets may adversely affect our operations, including the ability to fund the planned capital expenditures and potential new developments or acquisitions. Further, there is the risk that we will not be able to repay or refinance existing indebtedness or that the terms of any refinancing will not be as favorable as the terms of existing indebtedness. If we are unable to access capital markets to refinance our indebtedness on acceptable terms, we might be forced to dispose of properties on disadvantageous terms, which might result in losses.

The Operating Partnership guarantees debt or otherwise provides support for a number of joint venture properties.

Joint venture debt is the liability of the joint venture and is typically secured by a mortgage on the joint venture property. A default by a joint venture under its debt obligations may expose us to liability under a guaranty. We may elect to fund cash needs of a joint venture through equity contributions (generally on a basis proportionate to our ownership interests), advances or partner loans, although such funding is not typically required contractually or otherwise.

Our interest rate hedging arrangements may not effectively limit our interest rate risk exposure.

We manage our exposure to interest rate risk by periodically entering into interest rate hedging agreements to effectively fix a portion of our variable rate debt. Our use of interest rate hedging arrangements to manage risk associated with interest rate volatility may expose us to additional risks, including that a counterparty to a hedging arrangement may fail to honor its obligations. We enter into swaps that are exempt from the requirements of central clearing and/or trading on a designated contract market or swap execution facility pursuant to the applicable regulations and rules, and thus there may be more counterparty risk relative to others who do not utilize such exemption. Developing an effective interest rate risk strategy is complex and no strategy can completely insulate us from risks associated with interest rate fluctuations. There can be no assurance that our hedging activities will have the desired beneficial impact on our results of operations or financial condition. We might be subject to additional costs, such as transaction fees or breakage costs, if we terminate these arrangements.

Uncertainty relating to the determination of LIBOR and the phasing out of LIBOR after 2021 may adversely affect our results of operations, financial condition, liquidity and net worth.

In July 2017, the Financial Conduct Authority (“FCA”) that regulates the London Interbank Offered Rate (“LIBOR”) announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. As a result, the Federal Reserve Board and the Federal Reserve Bank of New York organized the Alternative Reference Rates Committee (“ARRC”), which identified the Secured Overnight Financing Rate (“SOFR”) as its preferred alternative to LIBOR in derivatives and other financial contracts. We are not able to predict when LIBOR may be limited or discontinued or when there will be sufficient liquidity in the SOFR market.

16

As of December 31, 2019, we had $401.4 million of debt and nine interest rate swaps with an aggregate notional value of $390.0 million outstanding that were indexed to LIBOR. In addition, we have a $600.0 million unsecured revolving line of credit facility that is indexed to LIBOR but had no borrowings under it.  We are monitoring and evaluating the risks related to potential changes in LIBOR availability, which include potential changes in interest paid on debt and amounts received and paid on interest rate swaps. In addition, the value of debt or derivative instruments tied to LIBOR could also be impacted when LIBOR is limited or discontinued and contracts must be transitioned to a new alternative rate. For some instruments, the method of transitioning to an alternative rate may be challenging, as they may require negotiation with the respective counterparty. If a contract is not transitioned to an alternative rate and LIBOR is discontinued, the impact on our contracts is likely to vary by contract.

While we expect LIBOR to be available in substantially its current form until the end of 2021, it is possible that LIBOR will become unavailable prior to that time. This could occur, for example, if a sufficient number of banks decline to make submissions to the LIBOR administrator. In that case, the risks associated with the transition to an alternative reference rate would be accelerated and/or magnified. Any of these events could have an adverse effect on our financing costs, and as a result, our financial condition, operating results and cash flows.

The market price of our common shares or other securities may fluctuate significantly in response to many factors.

Factors that could cause our securities to fluctuate significantly include but are not limited to; actual or anticipated variations in our operating results; cash flows or liquidity; changes in our earnings estimates or those of analysts; changes in our dividend policy; impairment charges affecting the carrying value of one or more of our outlet centers; changes in the general retail environment; shareholder activism and bankruptcy or brand-wide restructurings of retailers. In addition, a large proportion of our common shares has been and may continue to be traded by short sellers which may put pressure on the supply and demand for our common shares.

Risks Related to Federal Income Tax Laws

The Company's failure to qualify as a REIT could subject our earnings to corporate level taxation.

We believe that we have operated and intend to operate in a manner that permits the Company to qualify as a REIT under the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"). However, we cannot assure you that the Company has qualified or will remain qualified as a REIT. If in any taxable year the Company were to fail to qualify as a REIT and certain statutory relief provisions were not applicable, the Company would not be allowed a deduction for distributions to shareholders in computing taxable income and would be subject to U.S. federal income tax on our taxable income at the regular corporate rate. Also, we could be disqualified from treatment as a REIT for the four taxable years following the year during which qualification was lost. Accordingly, the Company's failure to qualify for taxation as a REIT would result in a significant reduction in cash available for distribution to our shareholders, and thus may adversely affect the market price and marketability of our securities.

The Company is required by law to make distributions to our shareholders.

To obtain the favorable tax treatment associated with the Company's qualification as a REIT, generally, the Company is required to distribute to its shareholders at least 90% of its net taxable income (excluding capital gains) each year. The Company depends upon distributions or other payments from the Operating Partnership to make distributions to the Company's common shareholders. The Company is allowed to satisfy the REIT income distribution requirement by distributing up to 80% of the dividends on its common shares in the form of additional common shares in lieu of paying dividends entirely in cash. Although we reserve the right to utilize this procedure in the future, we currently have no intent to do so.

Federal or state legislative or other actions could adversely affect our shareholders.

Future changes to tax laws may adversely affect the taxation of the REIT, its subsidiaries or its shareholders. These changes could have an adverse effect on an investment in our shares or on the market value or the resale potential of our assets.

17

These potential changes could generally result in REITs having fewer tax advantages, and may lead REITs to determine that it would be more advantageous to elect to be taxed, for federal income tax purposes, as a corporation.

Additionally, not all states automatically conform to changes in the Internal Revenue Code. This could increase the complexity of our compliance costs, and may subject us to additional tax and audit risk.

Risks Related to our Organizational Structure

The Company depends on distributions from the Operating Partnership to meet its financial obligations, including dividends.

The Company's operations are conducted by the Operating Partnership, and the Company's only significant asset is its interest in the Operating Partnership. As a result, the Company depends upon distributions or other payments from the Operating Partnership in order to meet its financial obligations, including its obligations under any guarantees or to pay dividends or liquidation payments to its common shareholders. As a result, these obligations are effectively subordinated to existing and future liabilities of the Operating Partnership. The Operating Partnership is a party to loan agreements with various bank lenders that require the Operating Partnership to comply with various financial and other covenants before it may make distributions to the Company. Although the Operating Partnership presently is in compliance with these covenants, there is no assurance that the Operating Partnership will continue to be in compliance and that it will be able to make distributions to the Company.

Risks Related to Cyber Security

Cyber-attacks or acts of cyber-terrorism could disrupt our business operations and information technology systems or result in the loss or exposure of confidential or sensitive customer, employee or Company information.

Our business operations and information technology systems may be attacked by individuals or organizations intending to disrupt our business operations and information technology systems, whether through cyber attacks or cyber-intrusions over the Internet, malware, computer viruses, attachments to e-mails, persons inside our organization, or persons with access to systems inside our organization. The risk of a security breach or disruption, particularly through cyber attacks or cyber-intrusion, including by computer hackers, foreign governments, and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. We use information technology systems to manage our outlet centers and other business processes. Disruption of those systems could adversely impact our ability to operate our business to provide timely service to our customers and maintain our relationships with our tenants. Accordingly, if such an attack or act of terrorism were to occur, our operations and financial results could be adversely affected. In addition, we use our information technology systems to protect confidential or sensitive customer, employee and Company information developed and maintained in the normal course of our business. Any attack on such systems that would result in the unauthorized release or loss of customer, employee or other confidential or sensitive data could have a material adverse effect on our business reputation, increase our costs and expose us to material legal claims and liability. As a result, if such an attack or act of terrorism were to occur, our operations and financial results and our share price could be adversely affected.

While we maintain some of our own critical information technology systems, we also depend on third parties to provide important information technology services relating to several key business functions, such as payroll, electronic communications and certain accounting and finance functions. Our measures to prevent, detect and mitigate these threats, including password protection, firewalls, backup servers, threat monitoring and periodic penetration testing, may not be successful in preventing a data breach or limiting the effects of a breach. Furthermore, the security measures employed by third-party service providers may prove to be ineffective at preventing breaches of their systems.

ITEM 1B. UNRESOLVED STAFF COMMENTS

There are no unresolved staff comments from the SEC for either the Company or the Operating Partnership.

ITEM 2. PROPERTIES

As of December 31, 2019, our consolidated portfolio consisted of 32 outlet centers totaling 12.0 million square feet located in 19 states. We own interests in seven other outlet centers totaling approximately 2.2 million square feet through unconsolidated joint ventures, including three outlet centers in Canada. Our consolidated outlet centers range in size from 104,009 to 739,110 square feet. The outlet centers are generally located near tourist destinations or along major interstate highways to provide visibility and accessibility to potential customers.

We believe that the outlet centers are well diversified geographically and by tenant and that we are not dependent upon any single property or tenant. The outlet center in Deer Park, New York is the only property that comprises 10% or more of our consolidated total assets as of December 31, 2019. No property comprises more than 10% of our consolidated revenues for the year ended December 31, 2019. See "Properties - Significant Property" for further details.

We have an ongoing strategy of acquiring outlet centers, developing new outlet centers and expanding existing outlet centers. See “Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources” for a discussion of the cost of such programs and the sources of financing thereof.

As of December 31, 2019, of the 32 outlet centers in our consolidated portfolio, we own the land underlying 26 and have ground leases on six. The following table sets forth information about the land leases on which all or a portion of the outlet centers are located:

Outlet Center	Acres	Expiration	Expiration including renewal terms at our option
Myrtle Beach Hwy 17, SC	40.0	2027	2096
Atlantic City, NJ	21.3	2101	2101
Sevierville, TN	43.6	2086	2086
Riverhead, NY	47.0	2024	2039
Mashantucket, CT (Foxwoods)	8.1	2040	2090
Rehoboth Beach, DE	2.7	2044	(1)

(1) Lease may be renewed at our option for additional terms of twenty years each.

Generally, our leases with our outlet center tenants typically have an initial term that ranges from 5 to 10 years and provide for the payment of fixed monthly rent in advance. There are often contractual base rent increases during the initial term of the lease. In addition, the rental payments are customarily subject to upward adjustments based upon tenant sales volume. A component of most leases includes a pro-rata share or escalating fixed contributions by the tenant for property operating expenses, including common area maintenance, real estate taxes, insurance and advertising and promotion, thereby reducing exposure to increases in costs and operating expenses resulting from inflation.

Significant Property

The Deer Park, New York outlet center is the only property that comprises 10% or more of our consolidated total assets. No property comprises more than 10% of our consolidated revenues.

Tenants at the Deer Park outlet center principally conduct retail sales operations. The following table shows occupancy and certain base rental information related to this property as of December 31, 2019, 2018, and 2017:

Deer Park	Square Feet	2019			2018			2017

Average base rental rates per weighted average square foot (1)		$	34.41		$	31.67		$	31.64

(1) Average annual base rent per square foot is calculated based on base rental revenues recognized during the year on a straight-line basis including non-cash adjustments to base rent required by GAAP and the effects of inducements and rent concessions.

Depreciation on the outlet centers is computed on the straight-line basis over the estimated useful lives of the assets. We generally use estimated lives up to 33 years for buildings, 15 years for land improvements and 7 years for equipment. Expenditures for ordinary repairs and maintenance are charged to operations as incurred while significant renovations and improvements, including tenant finishing allowances, which improve and/or extend the useful life of the asset are capitalized and depreciated over their estimated useful life. Real estate taxes assessed on this outlet center during 2019 amounted to $5.0 million. Real estate taxes for 2020 are estimated to be approximately $5.1 million.

The following table sets forth, as of December 31, 2019, scheduled lease expirations for the Deer Park outlet center assuming that none of the tenants exercise renewal options:

Holders

As of February 3, 2020, there were approximately 377 common shareholders of record.

Share Repurchases

In May 2017, we announced that our Board of Directors authorized the repurchase of up to $125 million of our outstanding common shares as market conditions warrant over a period commencing on May 19, 2017 and expiring on May 18, 2019. In February 2019, the Company’s Board of Directors authorized the repurchase of an additional $44.3 million of our outstanding common shares for an aggregate authorization of $169.3 million until May 2021. Repurchases may be made from time to time through open market, privately-negotiated, structured or derivative transactions (including accelerated stock repurchase transactions), or other methods of acquiring shares. The Company intends to structure open market purchases to occur within pricing and volume requirements of Rule 10b-18.  The Company may, from time to time, enter into Rule 10b5-1 plans to facilitate the repurchase of its shares under this authorization.

The following table summarizes our common share repurchases for the fiscal quarter ended December 31, 2019:

Period	Total number of shares purchased (1)	Average price paid per share		Total number of shares purchased as part of publicly announced plans or programs	Approximate dollar value of shares that may yet be purchased under the plans or programs (in millions)

The total number of shares withheld upon vesting was approximately 51,000 for the three months ended December 31, 2019.

Results of Operations

2019 Compared to 2018

Net Income

Net income increased $47.2 million in 2019 compared to 2018. The increase in net income is partially due to:

• the $43.4 million gain recorded on the sale of the four outlet centers in March 2019, and

• inclusion in the 2018 period a $49.7 million impairment charge related to our Jeffersonville outlet center.

The increase was partially offset by a decrease in net income due to:

• the sale of the four outlet centers in March 2019 discussed above,

• an additional impairment charge in the 2019 period related to our Jeffersonville outlet center of $37.6 million.

• a $4.4 million charge in the 2019 period related to the accelerated recognition of compensation cost as a result of a transition agreement (the “COO Transition Agreement”) with the Company’s former President and Chief Operating Officer in connection with his retirement, and

• a $3.6 million foreign currency loss recorded in the 2019 period upon the sale of the Bromont property by the RioCan Canada joint venture.

In the tables below, information set forth for properties disposed includes the four outlet centers sold in late March 2019. See "General Overview" in previous section for a list of properties sold during 2019.

Rental Revenues

Rental revenues decreased $16.8 million in the 2019 period compared to the 2018 period. The following table sets forth the changes in various components of rental revenues (in thousands):

	2019			2018			Increase/(Decrease)
Rental revenues from existing properties	$	449,333		$	450,092		$	(759	)
Rental revenues from properties disposed	6,321			25,647			(19,326		)
Straight-line rent adjustments	7,721			5,843			1,878
Lease termination fees	1,615			1,246			369
Amortization of above and below market rent adjustments, net	(1,044		)	(2,121		)	1,077
	$	463,946		$	480,707		$	(16,761	)

Rental revenues from existing properties decreased primarily due to lower average occupancy and rent modifications for certain tenants, in large part as a result of a number of bankruptcy filings and other tenant closures during 2018 and 2019. The decreases were offset partially by higher percentage rental revenues and temporary tenant revenues.

As a result of combining all components of a lease due to the adoption of Accounting Standards Codification Topic 842 “Leases” (“ASC 842”), all fixed contractual payments, including consideration received from certain executory costs, are now recognized on a straight-line basis. For the year ended December 31, 2019, we recorded $6.4 million in rental revenues in our consolidated statements of operations to record executory costs on a straight-line basis. These incremental straight-line rents were partially offset by the adjustment of straight-line rents related to certain bankrupt tenants.

Other Revenues

The following table sets forth the changes in various components of other income (in thousands):

	2019		2018		Increase/(Decrease)
Other revenues from existing properties	$	8,919	$	8,670	$	249
Other revenues from property disposed	64		309		(245		)
	$	8,983	$	8,979	$	4

37

Management, Leasing and Other Services

Management, leasing and other services increased $424,000 in the 2019 period compared to the 2018 period. The following table sets forth the changes in various components of management, leasing and other services (in thousands):

	2019		2018		Increase/(Decrease)
Management and marketing	$	2,308	$	2,334	$	(26	)
Leasing and other fees	126		162		(36		)
Expense reimbursements from unconsolidated joint ventures	2,985		2,499		486
Total Fees	$	5,419	$	4,995	$	424

Property Operating Expenses

Property operating expenses decreased $2.7 million in the 2019 period compared to the 2018 period. The following table sets forth the changes in various components of property operating expenses (in thousands):

	2019		2018		Increase/(Decrease)
Property operating expenses from existing properties	$	149,590	$	147,185	$	2,405
Property operating expenses from property disposed	2,580		8,140		(5,560		)
Expenses related to unconsolidated joint ventures	2,985		2,499		486
Other property operating expense	2,579		2,633		(54		)
	$	157,734	$	160,457	$	(2,723	)

Property operating expenses incurred at existing properties during the 2019 period increased primarily due to higher property taxes at certain centers and higher portfolio-wide property insurance costs.

General and Administrative Expenses

General and administrative expenses in the 2019 period increased $9.6 million compared to the 2018 period, primarily as a result of the $4.4 million charge related to the COO Transition Agreement. In addition, general and administrative expenses increased by approximately $4.9 million due to the adoption of the lease accounting standard ASC 842 in 2019 which requires indirect internal leasing and legal costs to be expensed as incurred. In the 2018 period, a portion of these indirect costs were capitalized.

Impairment Charges

During 2018, we determined that the estimated future undiscounted cash flows of our Jeffersonville outlet center did not exceed the property's carrying value. This shortfall was due to an expected decline in operating results caused by anticipated store closures from bankruptcy filings and brand-wide restructurings and a shift in the local competitive environment. Accordingly we recorded a $49.7 million impairment charge in our consolidated statement of operations which equaled the excess of the carrying value of our Jeffersonville outlet center over its estimated fair value. During 2019, in anticipation of further store closings and declining operating results, we recorded an additional impairment charge of $37.6 million in our consolidated statement of operations which equaled the excess of the carrying value of our Jeffersonville outlet center over its estimated fair value.

38

Depreciation and Amortization

Depreciation and amortization expense decreased $8.4 million in the 2019 period compared to the 2018 period. The following table sets forth the changes in various components of depreciation and amortization (in thousands):

	2019		2018		Increase/(Decrease)
Depreciation and amortization expenses from existing properties	$	122,058	$	126,295	$	(4,237	)
Depreciation and amortization from property disposed	1,256		5,427		(4,171		)
	$	123,314	$	131,722	$	(8,408	)

Depreciation and amortization decreased at our existing properties primarily due to the lower basis in our Jeffersonville property due to the impairment recorded in the third quarter of 2018 and due to lease related intangibles recorded as part of the acquisition price of acquired properties, which are amortized over shorter lives, becoming fully depreciated during the reporting periods.

Interest Expense

Interest expense decreased $3.1 million in the 2019 period compared to the 2018 period primarily from the use of the net proceeds from the sale of four properties in March 2019, as well as other general operating cash flows to reduce amounts outstanding on our unsecured lines of credit in the 2019 period. The decrease was partially offset by higher interest rates related to $150.0 million of interest rate swap agreements. In August 2018, certain 30-day LIBOR interest rate swaps with a rate of 1.3% expired and were replaced with new interest rate swaps with a rate of 2.2%.

Gain on Sale of Assets and Interests in Unconsolidated Entities

In March 2019, we sold four outlet centers for net proceeds of approximately $128.2 million, which resulted in a gain on sale of assets of $43.4 million.

Equity in Earnings of Unconsolidated Joint Ventures

Equity in earnings of unconsolidated joint ventures increased approximately $6.9 million in the 2019 period compared to the 2018 period. In the table below, information set forth for properties disposed includes the RioCan joint venture’s Bromont outlet center, which was sold in May 2019. The following table sets forth the changes in various components of equity in earnings of unconsolidated joint ventures (in thousands):

	2019		2018			Increase/(Decrease)
Equity in earnings from existing properties	$	7,831	$	2,671		$	5,160
Equity in earnings from property disposed	8		(1,747		)	1,755
	$	7,839	$	924		$	6,915

The increase in equity in earnings from existing properties is primarily due to including our share of impairment charges totaling $5.3 million related to the Saint-Sauveur outlet center in Canada during the 2018 period. The increase is partially offset in 2019 due to the full year effect of higher interest rates from debt refinancings in 2018 which converted the mortgages at both our Charlotte and National Harbor joint ventures from variable to fixed interest rates. In June 2018, the Charlotte joint venture closed on a $100.0 million mortgage loan with a fixed interest rate of approximately 4.3% and a maturity date of July 2028. This loan replaced the $90.0 million mortgage loan with an interest rate of LIBOR + 1.45%. In December 2018, the National Harbor joint venture closed on a $95.0 million mortgage loan with a fixed interest rate of approximately 4.6% and a maturity date of January 2030. This loan replaced the $87.0 million construction loan with an interest rate of LIBOR + 1.65%.

2018 Compared to 2017

Through its ownership of the sole general partner of the Operating Partnership, the Company has the full, exclusive and complete responsibility for the Operating Partnership's day-to-day management and control. The Company causes the Operating Partnership to distribute all, or such portion as the Company may in its discretion determine, of its available cash in the manner provided in the Operating Partnership's partnership agreement. The Company receives proceeds from equity issuances from time to time, but is required by the Operating Partnership's partnership agreement to contribute the proceeds from its equity issuances to the Operating Partnership in exchange for partnership units of the Operating Partnership.

We are a well-known seasoned issuer with a shelf registration which expires in March 2021 that allows the Company to register various unspecified classes of equity securities and the Operating Partnership to register various unspecified classes of debt securities. As circumstances warrant, the Company may issue equity from time to time on an opportunistic basis, dependent upon market conditions and available pricing. The Operating Partnership may use the proceeds to repay debt, including borrowings under its lines of credit, develop new or existing properties, make acquisitions of properties or portfolios of properties, invest in existing or newly created joint ventures, or for general corporate purposes.

The liquidity of the Company is dependent on the Operating Partnership's ability to make sufficient distributions to the Company. The Operating Partnership is a party to loan agreements with various bank lenders that require the Operating Partnership to comply with various financial and other covenants before it may make distributions to the Company. The Company also guarantees some of the Operating Partnership's debt. If the Operating Partnership fails to fulfill its debt requirements, which trigger the Company's guarantee obligations, then the Company may be required to fulfill its cash payment commitments under such guarantees. However, the Company's only material asset is its investment in the Operating Partnership.

The Company believes the Operating Partnership's sources of working capital, specifically its cash flow from operations, and borrowings available under its unsecured credit facilities, are adequate for it to make its distribution payments to the Company and, in turn, for the Company to make its dividend payments to its shareholders and to finance its continued operations, growth strategy and additional expenses we expect to incur for at least the next twelve months. However, there can be no assurance that the Operating Partnership's sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including its ability to make distribution payments to the Company. The unavailability of capital could adversely affect the Operating Partnership's ability to pay its distributions to the Company, which will in turn, adversely affect the Company's ability to pay cash dividends to its shareholders.

We operate in a manner intended to enable us to qualify as a REIT under the Internal Revenue Code, or the Code. For the Company to maintain its qualification as a REIT, it must pay dividends to its shareholders aggregating annually at least 90% of its taxable income. While historically the Company has satisfied this distribution requirement by making cash distributions to its shareholders, it may choose to satisfy this requirement by making distributions of cash or other property, including, in limited circumstances, the Company's own shares. Based on our 2019 estimated taxable income, we were required to distribute approximately $105.3 million to our shareholders in order to maintain our REIT status as described above. For tax reporting purposes, we distributed approximately $131.5 million during 2019. If in any taxable year the Company were to fail to qualify as a REIT and certain statutory relief provisions were not applicable, we would not be allowed a deduction for distributions to shareholders in computing taxable income and would be subject to U.S. federal income tax (including any applicable alternative minimum tax for tax years prior to 2018) on our taxable income at the regular corporate rate.

40

As a result of this distribution requirement, the Operating Partnership cannot rely on retained earnings to fund its on-going operations to the same extent that other companies whose parent companies are not real estate investment trusts can. The Company may need to continue to raise capital in the equity markets to fund the Operating Partnership's working capital needs, as well as potential developments of new or existing properties, acquisitions or investments in existing or newly created joint ventures.

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. The Company does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities and the revenues and expenses of the Company and the Operating Partnership are the same on their respective financial statements, except for immaterial differences related to cash, other assets and accrued liabilities that arise from public company expenses paid by the Company. However, all debt is held directly or indirectly at the Operating Partnership level, and the Company has guaranteed some of the Operating Partnership's unsecured debt as discussed below. Because the Company consolidates the Operating Partnership, the section entitled "Liquidity and Capital Resources of the Operating Partnership" should be read in conjunction with this section to understand the liquidity and capital resources of the Company on a consolidated basis and how the Company is operated as a whole.

In May 2017, we announced that our Board of Directors authorized the repurchase of up to $125 million of our outstanding common shares as market conditions warrant over a period commencing on May 19, 2017 and expiring on May 18, 2019. In February 2019, the Company’s Board of Directors authorized the repurchase of an additional $44.3 million of our outstanding common shares for an aggregate authorization of $169.3 million until May 2021. Repurchases may be made from time to time through open market, privately-negotiated, structured or derivative transactions (including accelerated share repurchase transactions), or other methods of acquiring shares. The Company intends to structure open market purchases to occur within pricing and volume requirements of Rule 10b-18.  The Company may, from time to time, enter into Rule 10b5-1 plans to facilitate the repurchase of its shares under this authorization.

Shares repurchased during the years ended December 31, 2019, 2018 and 2017 were as follows:

	Year Ended December 31,
	2019		2018		2017
Total number of shares purchased	1,209,328		919,249		1,911,585
Average price paid per share	$	16.52	$	21.74	$	25.80
Total price paid exclusive of commissions and related fees (in thousands)	$	19,976	$	19,980	$	49,324

The remaining amount authorized to be repurchased under the program as of December 31, 2019 was approximately $80.0 million.

In January 2020, the Company's Board of Directors declared a $0.355 cash dividend per common share payable on February 14, 2020 to each shareholder of record on January 31, 2020, and the Trustees of Tanger GP Trust declared a $0.355 cash distribution per Operating Partnership unit to the Operating Partnership's unitholders.

Additionally in January 2020, the Company's Board of Directors declared a quarterly dividend of $0.3575 cash dividend per common share payable on May 15, 2020 to holders of record on April 30, 2020, and the Trustees of Tanger GP Trust declared $0.3575 cash distribution per Operating Partnership unit to the Operating Partnership's unitholders.

Liquidity and Capital Resources of the Operating Partnership

General Overview

In this “Liquidity and Capital Resources of the Operating Partnership” section, the terms “we”, “our” and “us” refer to the Operating Partnership or the Operating Partnership and the Company together, as the text requires.

Property rental income represents our primary source to pay property operating expenses, debt service, capital expenditures and distributions, excluding non-recurring capital expenditures and acquisitions. To the extent that our cash flow from operating activities is insufficient to cover such non-recurring capital expenditures and acquisitions, we finance such activities from borrowings under our unsecured lines of credit or from the proceeds from the Operating Partnership’s debt offerings and the Company’s equity offerings.

We believe we achieve a strong and flexible financial position by attempting to: (1) maintain a conservative leverage position relative to our portfolio when pursuing new development, expansion and acquisition opportunities, (2) extend and sequence debt maturities, (3) manage our interest rate risk through a proper mix of fixed and variable rate debt, (4) maintain access to liquidity by using our lines of credit in a conservative manner and (5) preserve internally generated sources of capital by strategically divesting of our non-core assets and maintaining a conservative distribution payout ratio. We manage our capital structure to reflect a long-term investment approach and utilize multiple sources of capital to meet our requirements.

Statements of Cash Flows

The following table sets forth our changes in cash flows from 2019 and 2018 (in thousands):

	2019			2018			Change
Net cash provided by operating activities	$	220,391		$	258,277		$	(37,886	)
Net cash provided by (used in) investing activities	99,289			(40,023		)	139,312
Net cash used in financing activities	(312,133		)	(215,203		)	(96,930		)
Effect of foreign currency rate changes on cash and equivalents	(19		)	(110		)	91
Net increase in cash and cash equivalents	$	7,528		$	2,941		$	4,587

Operating Activities

The primary cause for the decrease in net cash provided by operating activities in the 2019 period was due to the sale of the four outlet centers in March 2019 as well changes in working capital and a slight decline in year over year operating results for our remaining centers.

Investing Activities

The primary cause for the increase in net cash provided by investing activities was due to the net proceeds of approximately $128.2 million from the sale of the four outlet centers in the 2019 period. In addition, the 2019 period had lower levels of development activity than the 2018 period.

Financing Activities

The primary cause for the increase in net cash used in financing activities was due to the use of the proceeds from the sale of the four outlet centers to pay down our unsecured lines of credit.

42

Development Activities

Development in Unconsolidated Real Estate Joint Ventures

From time to time, we form joint venture arrangements to develop outlet centers. See "Off-Balance Sheet Arrangements" for a discussion of unconsolidated joint venture development activities.

Potential Future Developments, Acquisitions and Dispositions

As of the date of this filing, we are in the initial study period for potential new developments, including a potential site in Nashville, Tennessee. We may also use joint venture arrangements to develop other potential sites or acquire existing centers. There can be no assurance, however, that these potential future projects will ultimately be developed or that additional centers will be acquired.

In the case of projects to be wholly-owned by us, we expect to fund these projects with borrowings under our unsecured lines of credit and cash flow from operations, but may also fund them with capital from additional public debt and equity offerings. For projects to be developed through joint venture arrangements, we may use collateralized construction loans to fund a portion of the project, with our share of the equity requirements funded from sources described above.

We intend to continue to grow our portfolio by developing, expanding or acquiring additional outlet centers. However, you should note that any developments or expansions that we, or a joint venture that we have an ownership interest in, have planned or anticipated may not be started or completed as scheduled, or may not result in accretive net income or funds from operations ("FFO"). See the section "Non-GAAP Supplemental Earnings Measures" - "Funds From Operations" below for further discussion of FFO. In addition, we regularly evaluate acquisition or disposition proposals and engage from time to time in negotiations for acquisitions or dispositions of properties. We may also enter into letters of intent for the purchase or sale of properties. Any prospective acquisition or disposition that is being evaluated or which is subject to a letter of intent may not be consummated, or if consummated, may not result in an increase in earnings or liquidity.

Financing Arrangements

See Notes 8 and 9 to the Consolidated Financial Statements, for details of our current outstanding debt, financing transactions that have occurred over the past three years and debt maturities. As of December 31, 2019, unsecured borrowings represented 95% of our outstanding debt and 92% of the gross book value of our real estate portfolio was unencumbered. As of December 31, 2019, 1% of our outstanding debt, excluding variable rate debt with interest rate protection agreements in place, had variable interest rates and therefore was subject to market fluctuations.

We maintain unsecured lines of credit that, as of December 31, 2019, provided for borrowings of up to $600.0 million, including a separate $20.0 million liquidity line and a $580.0 million syndicated line. The syndicated line may be increased up to $1.2 billion through an accordion feature in certain circumstances. As of December 31, 2019, we had no borrowings and letters of credit totaling $170,000 outstanding under the lines of credit.

We intend to retain the ability to raise additional capital, including public debt or equity, to pursue attractive investment opportunities that may arise and to otherwise act in a manner that we believe to be in the best interests of our shareholders and unitholders. The Company is a well-known seasoned issuer with a joint shelf registration statement on Form S-3 with the Operating Partnership, expiring in March 2021, that allows us to register unspecified amounts of different classes of securities. To generate capital to reinvest into other attractive investment opportunities, we may also consider the use of additional operational and developmental joint ventures, the sale or lease of outparcels on our existing properties and the sale of certain properties that do not meet our long-term investment criteria. Based on cash provided by operations, existing lines of credit, ongoing relationships with certain financial institutions and our ability to sell debt or issue equity subject to market conditions, we believe that we have access to the necessary financing to fund the planned capital expenditures for at least the next twelve months.

43

We anticipate that adequate cash will be available to fund our operating and administrative expenses, regular debt service obligations, and the payment of dividends in accordance with REIT requirements in both the short and long-term. Although we receive most of our rental payments on a monthly basis, distributions to shareholders and unitholders are made quarterly and interest payments on the senior, unsecured notes are made semi-annually. Amounts accumulated for such payments will be used in the interim to reduce the outstanding borrowings under our existing unsecured lines of credit or invested in short-term money market or other suitable instruments.

We believe our current balance sheet position is financially sound; however, due to the uncertainty and unpredictability of the capital and credit markets, we can give no assurance that affordable access to capital will exist between now and when our next significant debt matures, which is our senior unsecured notes with a principal amount outstanding of $250.0 million and a maturity in December of 2023. Our unsecured lines of credit expire in 2021, with a one-year extension option that may extend the maturity to 2022.  At December 31, 2019, there was no balance outstanding on our unsecured lines of credit, which provide for borrowings up to $600.0 million.

The interest rate spreads associated with our unsecured lines of credit and our unsecured term loan are based on the higher of our two investment grade credit ratings.  Changes to our credit ratings could cause our interest rate spread to adjust accordingly. February 2020, due to a change in our credit rating, our interest rate spread over LIBOR on our $600.0 million unsecured line of credit facility increased from 0.875% to 1.0% and our annual facility fee increased from 0.15% to 0.20%. As of December 31, 2019, there we no outstanding balances under our unsecured lines of credit. In addition, our interest rate spread over LIBOR on our $350.0 million unsecured term loan increased from 0.90% to 1.0%.

Our debt agreements contain covenants that require the maintenance of certain ratios, including debt service coverage and leverage, and limit the payment of dividends such that dividends and distributions will not exceed funds from operations, as defined in the agreements, for the prior fiscal year on an annual basis or 95% on a cumulative basis. We have historically been and currently are in compliance with all of our debt covenants. We expect to remain in compliance with all our existing debt covenants; however, should circumstances arise that would cause us to be in default, the various lenders would have the ability to accelerate the maturity on our outstanding debt.

We believe our most restrictive financial covenants are contained in our senior, unsecured notes. Key financial covenants and their covenant levels, which are calculated based on contractual terms, include the following:

Senior unsecured notes financial covenants	Required	Actual
Total consolidated debt to adjusted total assets	< 60%	48	%
Total secured debt to adjusted total assets	< 40%	3	%
Total unencumbered assets to unsecured debt	> 150%	198	%

Capital Expenditures

The following table details our capital expenditures for the years ended December 31, 2019 and 2018, respectively (in thousands):

	2019			2018		Change
Capital expenditures analysis:
New outlet center developments and expansions	$	8,865		$	8,863	$	2
Renovations	2,930			4,690		(1,760		)
Second generation tenant allowances	18,189			15,729		2,460
Other capital expenditures	20,133			19,075		1,058
	50,117			48,357		1,760
Conversion from accrual to cash basis	(2,232		)	15,896		(18,128		)
Additions to rental property-cash basis	$	47,885		$	64,253	$	(16,368	)

Contractual Obligations and Commercial Commitments

The following table details our contractual obligations over the next five years and thereafter as of December 31, 2019 (in thousands):

Contractual Obligations	2020		2021		2022		2023		2024		Thereafter		Total
Debt (1)	$	3,566	$	57,193	$	4,436	$	254,768	$	605,140	$	657,206	$	1,582,309
Interest payments (2)	55,291		53,511		51,672		50,533		34,721		48,517		294,245
Operating leases	5,568		5,613		5,669		5,709		5,765		226,876		255,200
Other contractual obligations	1,431		1,239		1,158		1,148		1,148		4,527		10,651
	$	65,856	$	117,556	$	62,935	$	312,158	$	646,774	$	937,126	$	2,142,405

(1) These amounts represent total future cash payments related to debt obligations outstanding as of December 31, 2019.

(2) These amounts represent future interest payments related to our debt obligations based on the fixed and variable interest rates specified in the associated debt agreements, including the effects of our interest rate swaps. All of our variable rate debt agreements are based on the one month LIBOR rate, thus for purposes of calculating future interest amounts on variable interest rate debt, the one month LIBOR rate as of December 31, 2019 was used.

In addition to the contractual payment obligations shown in the table above, we have commitments of $1.8 million remaining as of December 31, 2019 related to contracts to complete construction, development activity at outlet centers, and other capital expenditures throughout our consolidated portfolio. These amounts would be primarily funded by amounts available under our unsecured lines of credit but could also be funded by other sources of capital, such as collateralized construction loans or public debt and equity offerings. In addition, we have commitments to pay approximately $15.9 million in tenant allowances for leases that are executed but where the tenant improvements have not been constructed. Payments are only made upon the tenant opening its store, completing its interior construction and submitting the necessary documentation required per its lease. There were no significant contractual commitments to complete construction and development activity related to our unconsolidated joint ventures as of December 31, 2019. In addition, commitments related to tenant allowances at our unconsolidated joint ventures totaled approximately $1.0 million at December 31, 2019, of which our portion was approximately $481,000. Contractual commitments represent only those costs subject to contracts which are legally binding agreements as of December 31, 2019 and do not necessarily represent the total cost to complete the projects.

45

Off-Balance Sheet Arrangements

We have partial ownership interests in seven unconsolidated outlet centers totaling approximately 2.2 million square feet, including 3 outlet centers in Canada. See Note 6 to the Consolidated Financial Statements for details of our individual joint ventures, including, but not limited to, carrying values of our investments, fees we receive for services provided to the joint ventures, recent development and financing transactions and condensed combined summary financial information.

We may elect to fund cash needs of a joint venture through equity contributions (generally on a basis proportionate to our ownership interests), advances or partner loans, although such funding is not typically required contractually or otherwise. 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 and intend to provide further financial support to these joint ventures. We believe our joint ventures will be able to fund their operating and capital needs during 2020 based on their sources of working capital, specifically cash flow from operations, access to contributions from partners, and ability to refinance debt obligations, including the ability to exercise upcoming extensions of near term maturities.

Our joint ventures are typically encumbered by a mortgage on the joint venture property. We provide guarantees to lenders for our joint ventures which include standard non-recourse carve out indemnifications for losses arising from items such as but not limited to fraud, physical waste, payment of taxes, environmental indemnities, misapplication of insurance proceeds or security deposits and failure to maintain required insurance. A default by a joint venture under its debt obligations may expose us to liability under the guaranty. For construction and mortgage loans, we may include a guaranty of completion as well as a principal guaranty ranging from 5% to 100% of principal.  The principal guarantees include terms for release based upon satisfactory completion of construction and performance targets including occupancy thresholds and minimum debt service coverage tests. Our joint ventures may contain make whole provisions in the event that demands are made on any existing guarantees.

RioCan Canada

In May 2019, the RioCan joint venture closed on the sale of its outlet center in Bromont, for net proceeds of approximately $6.4 million. Our share of the proceeds was approximately $3.2 million. As a result of this transaction, we recorded a foreign currency loss of approximately $3.6 million in other income (expense), which had been previously recorded in other comprehensive income (loss).

Debt of unconsolidated joint ventures

The following table details information regarding the outstanding debt of the unconsolidated joint ventures and guarantees of such debt provided by us as of December 31, 2019 (dollars in millions):

Joint Venture	Total Joint Venture Debt			Maturity Date	Interest Rate		Percent Guaranteed by the Operating Partnership		Maximum Guaranteed Amount by the Company
Charlotte	$	100.0		July 2028	4.27	%	—	%	$	—
Columbus (1)	85.0			November 2020	LIBOR + 1.65%		7.5	%	6.4
Galveston/Houston	80.0			July 2020	LIBOR + 1.65%		12.5	%	10.0
National Harbor	95.0			January 2030	4.63	%	—	%	—
RioCan Canada	9.1			May 2020	5.75	%	33.0	%	3.0
Debt premium and debt origination costs	(1.1		)
	$	368.0							$	19.4

(1) In October 2019, the joint venture exercised its option to extend the mortgage loan for one year to November 2020 under the same terms. The mortgage loan has one remaining one-year extension option.

46

Our joint ventures are generally subject to buy-sell provisions which are customary for joint venture agreements in the real estate industry. Either partner may initiate these provisions (subject to any applicable lock up period), which could result in either the sale of our interest or the use of available cash or additional borrowings to acquire the other party's interest. Under these provisions, one partner sets a price for the property, then the other partner has the option to either (1) purchase their partner's interest based on that price or (2) sell its interest to the other partner based on that price. Since the partner other than the partner who triggers the provision has the option to be the buyer or seller, we do not consider this arrangement to be a mandatory redeemable obligation.

Impairments

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, the joint venture recognizes an impairment loss in an amount by which the carrying amount exceeds its fair value.

During 2018 and 2017 the Rio-Can joint venture recognized impairment charges related to its properties located in Bromont, Quebec and Saint Sauveur, Quebec. The impairment charges were primarily driven by, among other things, new competition in the market and changes in market capitalization rates. While the joint venture believes the Saint Sauveur property is recorded at fair value, there can be no assurance that additional impairment charges will not be recognized.

The table below summarizes the impairment charges taken during 2018 and 2017 (in thousands):

		Impairment Charges(1)
	Outlet Center	Total		Our Share
2018	Bromont and Saint Sauveur	$	14,359	$	7,180
2017	Bromont and Saint Sauveur	18,042		9,021

(1) The fair value was determined using an income approach considering the prevailing market income capitalization rates for similar assets.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with U.S. generally accepted accounting principles (“GAAP”) and the Company’s discussion and analysis of its financial condition and operating results require the Company’s management to make judgments, assumptions and estimates that affect the amounts reported. Note 2, Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K describes the significant accounting policies and methods used in the preparation of the Company’s consolidated financial statements. Management bases its estimates on historical experience and on various other assumptions it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates, and such differences may be material. Management believes the Company’s critical accounting policies and estimates are those related to principles of consolidation, rental property, impairment of long-lived assets, impairment of investments and revenue recognition. Management considers these policies critical because they are both important to the portrayal of the Company’s financial condition and operating results, and they require management to make judgments and estimates about inherently uncertain matters. The Company’s senior management has reviewed these critical accounting policies and related disclosures with the Audit Committee of the Company’s Board of Directors.

47

Impairments

Based upon current market conditions, one of our outlet centers has an estimated fair value significantly less than its recorded carrying value of approximately $100.0 million. However, based on our current plan with respect to that outlet center, we believe that its carrying amount is recoverable and therefore no impairment charge was recorded. Accordingly, we will continue to monitor circumstances and events in future periods that could affect inputs such as the expected holding period, operating cash flow forecasts and capitalization rates, utilized to determine whether an impairment charge is necessary.  As these inputs are difficult to predict and are subject to future events that may alter our assumptions, the future cash flows estimated by management in its impairment analysis may not be achieved, and actual losses or impairment may be realized in the future. The total projected undiscounted cash flows did not significantly exceed the carrying value and therefore we can provide no assurance that material impairment charges with respect to our outlet centers will not occur in 2020 or future periods.

New Accounting Pronouncements

See Note 2 and Note 21 to the consolidated financial statements for information on recently adopted accounting standards and new accounting pronouncements issued.

New Auditing Standard

On June 1, 2017, the Public Company Accounting Oversight Board issued Auditing Standard 3101, The Auditor's Report on an Audit of Financial Statements When the Auditor Expresses an Unqualified Opinion (“AS 3101”). As a result of AS 3101, the most significant change to the auditor’s report on the financial statements is a new requirement to describe critical audit matters arising from the audit of the current period’s financial statements in the auditor’s report. The requirements related to critical audit matters in AS 3101 were effective for audits of fiscal years ending on or after June 30, 2019, for large accelerated filers; and for fiscal years ending on or after December 15, 2020, for all other companies to which the requirements apply. Therefore, critical audit matters are included in the Report of Independent Registered Public Accounting Firm for Tanger Factory Outlet Centers, Inc.'s consolidated financial statements as of and for the year ended December 31, 2019, and will be included in the Report of Independent Registered Public Accounting Firm for Tanger Properties Limited Partnership's consolidated financial statements as of and for the year ended December 31, 2020.

NON-GAAP SUPPLEMENTAL MEASURES

Funds From Operations

FFO is a widely used measure of the operating performance for real estate companies that supplements net income (loss) determined in accordance with GAAP.  We determine FFO based on the definition set forth by the National Association of Real Estate Investment Trusts (“NAREIT”), of which we are a member. In December 2018, NAREIT issued “NAREIT Funds From Operations White Paper - 2018 Restatement” which clarifies, where necessary, existing guidance and consolidates alerts and policy bulletins into a single document for ease of use. NAREIT defines FFO as net income/(loss) available to the Company’s common shareholders computed in accordance with GAAP, excluding (i) depreciation and amortization related to real estate, (ii) gains or losses from sales of certain real estate assets, (iii) gains and losses from change in control, (iv) impairment write-downs of certain real estate assets and investments in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity and (v) after adjustments for unconsolidated partnerships and joint ventures calculated to reflect FFO on the same basis.

FFO is intended to exclude historical cost depreciation of real estate as required by GAAP which assumes that the value of real estate assets diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization of real estate assets, gains and losses from property dispositions and extraordinary items, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, development activities and interest costs, providing perspective not immediately apparent from net income.

We present FFO because we consider it an important supplemental measure of our operating performance. In addition, a portion of cash bonus compensation to certain members of management is based on our FFO or Adjusted Funds From Operations (“AFFO”), which is described in the section below. We believe it is useful for investors to have enhanced transparency into how we evaluate our performance and that of our management. In addition, FFO is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, many of which present FFO when reporting their results. FFO is also widely used by us and others in our industry to evaluate and price potential acquisition candidates. NAREIT has encouraged its member companies to report their FFO as a supplemental, industry-wide standard measure of REIT operating performance.

FFO has significant limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

• FFO does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments;

• FFO does not reflect changes in, or cash requirements for, our working capital needs;

• Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and FFO does not reflect any cash requirements for such replacements; and

• Other companies in our industry may calculate FFO differently than we do, limiting its usefulness as a comparative measure.

Because of these limitations, FFO should not be considered as a measure of discretionary cash available to us to invest in the growth of our business or our dividend paying capacity. We compensate for these limitations by relying primarily on our GAAP results and using FFO only as a supplemental measure.

49

Adjusted Funds From Operations

We present AFFO as a supplemental measure of our performance. We define AFFO as FFO further adjusted to eliminate the impact of certain items that we do not consider indicative of our ongoing operating performance. These further adjustments are itemized in the table below. You are encouraged to evaluate these adjustments and the reasons we consider them appropriate for supplemental analysis. In evaluating AFFO you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation. Our presentation of AFFO should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

We present AFFO because we believe it assists investors and analysts in comparing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. In addition, we believe it is useful for investors to have enhanced transparency into how we evaluate management’s performance and the effectiveness of our business strategies. We use AFFO when certain material, unplanned transactions occur as a factor in evaluating management’s performance and to evaluate the effectiveness of our business strategies, and may use AFFO when determining incentive compensation.

AFFO has limitations as an analytical tool. Some of these limitations are:

• AFFO does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments;

• AFFO does not reflect changes in, or cash requirements for, our working capital needs;

• Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and AFFO does not reflect any cash requirements for such replacements;

• AFFO does not reflect the impact of certain cash charges resulting from matters we consider not to be indicative of our ongoing operations; and

• Other companies in our industry may calculate AFFO differently than we do, limiting its usefulness as a comparative measure.

Because of these limitations, AFFO should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP. We compensate for these limitations by relying primarily on our GAAP results and using AFFO only as a supplemental measure.

Portfolio Net Operating Income and Same Center NOI

We present portfolio net operating income (“Portfolio NOI”) and same center net operating income (“Same Center NOI”) as supplemental measures of our operating performance. Portfolio NOI represents our property level net operating income which is defined as total operating revenues less property operating expenses and excludes termination fees and non-cash adjustments including straight-line rent, net above and below market rent amortization, impairment charges and gains or losses on the sale of assets recognized during the periods presented. We define Same Center NOI as Portfolio NOI for the properties that were operational for the entire portion of both comparable reporting periods and which were not acquired or subject to a material expansion or non-recurring event, such as a natural disaster, during the comparable reporting periods.

We believe Portfolio NOI and Same Center NOI are non-GAAP metrics used by industry analysts, investors and management to measure the operating performance of our properties because they provide performance measures directly related to the revenues and expenses involved in owning and operating real estate assets and provide a perspective not immediately apparent from net income, FFO or AFFO. Because Same Center NOI excludes properties developed, redeveloped, acquired and sold; as well as non-cash adjustments, gains or losses on the sale of outparcels and termination rents; it highlights operating trends such as occupancy levels, rental rates and operating costs on properties that were operational for both comparable periods. Other REITs may use different methodologies for calculating Portfolio NOI and Same Center NOI, and accordingly, our Portfolio NOI and Same Center NOI may not be comparable to other REITs.

Portfolio NOI and Same Center NOI should not be considered alternatives to net income (loss) or as an indicator of our financial performance since they do not reflect the entire operations of our portfolio, nor do they reflect the impact of general and administrative expenses, acquisition-related expenses, interest expense, depreciation and amortization costs, other non-property income and losses, the level of capital expenditures and leasing costs necessary to maintain the operating performance of our properties, or trends in development and construction activities which are significant economic costs and activities that could materially impact our results from operations. Because of these limitations, Portfolio NOI and Same Center NOI should not be viewed in isolation or as a substitute for performance measures calculated in accordance with GAAP. We compensate for these limitations by relying primarily on our GAAP results and using Portfolio NOI and Same Center NOI only as supplemental measures.

Outlet centers sold:
Nags Head, Ocean City, Park City, and Williamsburg	March 2019

Economic Conditions and Outlook

The majority of our leases contain provisions designed to mitigate the impact of inflation. Such provisions include clauses for the escalation of base rent and clauses enabling us to receive percentage rentals based on tenants' gross sales (above predetermined levels), which generally increase as prices rise. A component of most leases includes a pro-rata share or escalating fixed contributions by the tenant for property operating expenses, including common area maintenance, real estate taxes, insurance and advertising and promotion, thereby reducing exposure to increases in costs and operating expenses resulting from inflation.

A portion of our rental revenues are derived from percentage rents that directly depend on the sales volume of certain tenants. Accordingly, declines in these tenants' sales would reduce the income produced by our properties. If the sales or profitability of our retail tenants decline sufficiently, whether due to a change in consumer preferences, legislative changes that increase the cost of their operations or otherwise, such tenants may be unable to pay their existing rents as such rents would represent a higher percentage of their sales.

Our outlet centers typically include well-known, national, brand name companies. By maintaining a broad base of well-known tenants and a geographically diverse portfolio of properties located across the United States, we believe we reduce our operating and leasing risks. No one tenant (including affiliates) accounts for more than 8% of our square feet or 7% of our rental revenues.

Due to the relatively short-term nature of our tenants’ leases, a significant portion of the leases in our portfolio come up for renewal each year. As of January 1, 2019, we had approximately 1.3 million square feet, or 11% of our consolidated portfolio at that time coming up for renewal during 2019, excluding the outlet centers sold in March 2019. As of December 31, 2019, we had renewed approximately 77% of this space. In addition, for the twelve months ended December 31, 2019, we completed renewals and re-tenanted space totaling 1.5 million square feet at a blended 2.7% increase in average base rental rates compared to the expiring rates. During 2020, approximately 1.7 square feet, or 14%, of our current consolidated portfolio will come up for renewal.

53

The current challenging retail environment has impacted our business as our operations are subject to the operating results and operating decisions of our retail tenants. As is typical in the retail industry, certain tenants have closed, or will close, certain stores by terminating their lease prior to its natural expiration or as a result of filing for protection under bankruptcy laws, or may request modifications to their existing lease terms. During the year ended December 31, 2019, we recaptured approximately 198,000 square feet within the consolidated portfolio related to bankruptcies and brand-wide restructurings by retailers, compared to 126,000 square feet during the year ended December 31, 2018.

We expect other store closings to impact our operating results in 2020. We have already recaptured 303,000 square feet in January 2020 related to all of the Dressbarn and Kitchen Collection stores and certain Forever 21 and Destination Maternity stores. If not released, this would represent a reduction of approximately 350 basis points of Same Center NOI. We also estimate that there may be 322,000 to 372,000 square feet of potential additional store closings that are unknown or unresolved at this time. Largely due to the number of recent and/or anticipated bankruptcy filings, store closings and rent adjustments, we currently expect our Same Center NOI for 2020 to decline compared to 2019. 

We believe outlet stores will continue to be a profitable and fundamental distribution channel for many brand name manufacturers. While we continue to attract and retain additional tenants, if we were unable to successfully renew or re-lease a significant amount of this space on favorable economic terms or in a timely manner, the loss in rent and our Same Center NOI could be further negatively impacted in 2020. Occupancy at our consolidated centers was 97.0% and 96.8% as of December 31, 2019 and 2018, respectively.

ITEM 7A.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

We are exposed to various market risks, including changes in interest rates. Market risk is the potential loss arising from adverse changes in market rates and prices, such as interest rates.

Interest Rate Risk

We may periodically enter into certain interest rate protection and interest rate swap agreements to effectively convert existing floating rate debt to a fixed rate basis. We do not enter into derivatives or other financial instruments for trading or speculative purposes. We currently have interest rate swap agreements to fix the interest rates on outstanding debt with notional amounts totaling $390.0 million. See Note 10 to the Consolidated Financial Statements for additional details related to our outstanding derivatives.

As of December 31, 2019, 1% of our outstanding consolidated debt, excluding the amount of variable rate debt with interest rate protection agreements in place, had variable interest rates and therefore was subject to market fluctuations. A change in the LIBOR index of 100 basis points would result in an increase or decrease of approximately $114,000 in interest expense on an annual basis.

The interest rate spreads associated with our unsecured lines of credit and our unsecured term loan are based on the higher of our two investment grade credit ratings. Changes to our credit ratings could cause our interest rate spread to adjust accordingly. In February 2020, due to a change in our credit rating, our interest rate spread over LIBOR on our $600.0 million unsecured line of credit facility increased from 0.875% to 1.0% and our annual facility fee increased from 0.15% to 0.20%. As of December 31, 2019, there were no outstanding balances under our unsecured lines of credit. In addition, our interest rate spread over LIBOR on our $350.0 million unsecured term loan increased from 0.90% to 1.0%. If additional decreases to our credit ratings occurs, interest expense could increase depending upon the level of downgrade.

The information presented herein is merely an estimate and has limited predictive value.  As a result, the ultimate effect upon our operating results of interest rate fluctuations will depend on the interest rate exposures that arise during the period, our hedging strategies at that time and future changes in the level of interest rates.

54

The estimated fair value and recorded value of our debt consisting of senior unsecured notes, unsecured term loans, secured mortgages and unsecured lines of credit was as follows (in thousands):

	December 31, 2019		December 31, 2018
Fair value of debt	$	1,603,814	$	1,668,475
Recorded value of debt	$	1,569,773	$	1,712,918

A 100 basis point increase from prevailing interest rates at December 31, 2019 and December 31, 2018 would result in a decrease in fair value of total consolidated debt of approximately $62.9 million and $65.6 million, respectively. Refer to Note 11 to the consolidated financial statements for a description of our methodology in calculating the estimated fair value of debt. Considerable judgment is necessary to develop estimated fair values of financial instruments. Accordingly, the estimates presented herein are not necessarily indicative of the amounts we could realize on the disposition of the financial instruments.

Foreign Currency Risk

We are also exposed to foreign currency risk on investments in outlet centers that are located in Canada. Our currency exposure is concentrated in the Canadian Dollar. To mitigate the risk related to changes in foreign currency, cash flows received from our Canadian joint ventures are either reinvested to fund ongoing Canadian development activities, if applicable, or converted to U.S. dollars and utilized to repay amounts outstanding under our unsecured lines of credit. Accordingly, cash held in Canadian Dollars at any point in time is insignificant. We generally do not hedge currency translation exposures.

ITEM 9A. CONTROLS AND PROCEDURES

Tanger Factory Outlet Centers, Inc.

(a) Evaluation of disclosure control procedures.

The Chief Executive Officer, Steven B. Tanger (Principal Executive Officer), and Chief Financial Officer, James F. Williams (Principal Financial Officer), evaluated the effectiveness of the Company's disclosure controls and procedures on December 31, 2019 and concluded that, as of that date, the Company's disclosure controls and procedures were effective to ensure that the information the Company is required to disclose in its filings with the SEC under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms, and to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company's management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

(b) Management's report on internal control over financial reporting.

Internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, is a process designed by, or under the supervision of, the Company's Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, and effected by the Company's board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.  The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining policies and procedures designed to maintain the adequacy of the Company's internal control over financial reporting, including those policies and procedures that:

(1) Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

(2) Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

(3) Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements.

The Company's management has evaluated the effectiveness of the Company's internal control over financial reporting as of December 31, 2019 based on the criteria established in a report entitled Internal Control-Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission.  Based on our assessment and those criteria, the Company's management has concluded that the Company's internal control over financial reporting was effective at the reasonable assurance level as of December 31, 2019.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

The effectiveness of the Company's internal control over financial reporting as of December 31, 2019 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which appears herein.

(c) There were no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during our last fiscal quarter ended December 31, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The table below provides information as of December 31, 2019 with respect to compensation plans under which our equity securities are authorized for issuance. 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 "common shares" is meant to also include corresponding units of the Operating Partnership.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Tanger Factory Outlet Centers, Inc.    

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Tanger Factory Outlet Centers, Inc. and subsidiaries (the "Company") as of December 31, 2019 and 2018, the related consolidated statements of operations, comprehensive income, shareholders' equity, and cash flows, for each of the three years in the period ended December 31, 2019, and the related notes and the schedule listed in the Index at Item 15(a)(2) (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 19, 2020, expressed an unqualified opinion on the Company's internal control over financial reporting.

Change in Accounting Principle

As discussed in Note 21 to the financial statements, effective January 1, 2019, the Company adopted Financial Accounting Standards Board Accounting Standards Codification Topic 842, Leases, using the modified retrospective approach.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Impairment of long-lived assets - Refer to Notes 2 and 11 to the financial statements

Critical Audit Matter Description

Rental property held and used by the Company is reviewed for impairment in the event that facts and circumstances indicate that the carrying amount of an asset may not be recoverable. In such event, the Company compares the estimated future undiscounted cash flows associated with the asset to the asset’s carrying amount, and if less than such carrying amount, recognizes an impairment loss in an amount by which the carrying amount exceeds its fair value. The cash flow estimates used both for determining recoverability and estimating fair value are inherently judgmental and reflect current and projected trends in rental, occupancy, capitalization, and discount rates, and estimated holding periods for the applicable assets. Total rental property as of December 31, 2019, was approximately $1.9 billion. During the year ended December 31, 2019, the Company recorded an impairment charge of approximately $37.6 million.

Given the Company’s cash flow estimates used both for determining recoverability and estimating fair value to determine impairment require management to make significant estimates and assumptions related to current and projected trends in rental, occupancy, capitalization, and discount rates, and estimated holding periods, performing audit procedures to evaluate the reasonableness of management’s undiscounted and discounted future cash flows analysis required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists.

F-1

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the undiscounted or discounted future cash flows analysis and the assessment of expected remaining holding period included the following, among others:

• We tested the effectiveness of controls over management’s evaluation of the recoverability of rental property assets and management’s estimate of fair value to determine impairment, including those over rental, occupancy, capitalization, and discount rates, and estimated holding periods.

• We evaluated the undiscounted and discounted future cash flows analysis, including estimates of rental, occupancy, capitalization, and discount rates, and estimated holding periods for each rental property asset with possible impairment indicators by (1) evaluating the source information and assumptions used by management, which included the use of our fair value specialists for certain of these assumptions, and (2) testing the mathematical accuracy of the undiscounted and discounted future cash flows analysis.

• We evaluated the reasonableness of management’s undiscounted and discounted future cash flows analysis by comparing management’s projections to the Company’s historical results and external market sources.

Impairment of Investments - Refer to Notes 2 and 6 to the financial statements

Critical Audit Matter Description

On a periodic basis, the Company assesses whether there are any indicators that the value of the 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 an other than temporary impairment has occurred, the loss shall be measured as the excess of the carrying amount of the investment over the value of the investment. The Company’s 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, the discount and capitalization rates. As the discount and capitalization rates are difficult to predict, the values estimated by the Company in the impairment analysis may not be realized. Total investments in unconsolidated joint ventures as of December 31, 2019, were $94.7 million.

Given the Company’s evaluation of the impairment of investments in unconsolidated joint ventures requires management to make significant estimates and assumptions related to the discount and capitalization rates, performing audit procedures to evaluate the reasonableness of management’s analysis and assessment required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the discount and capitalization rates included the following, among others:

• We tested the effectiveness of controls over management’s selection of the discount and capitalization rates and management’s evaluation of whether the impairments in their investments in unconsolidated joint ventures are other than temporary.

• We evaluated the reasonableness of the valuation methodology.

• With the assistance of our fair value specialists, we evaluated the discount and capitalization rates by evaluating the source information and assumptions used by management.

• We tested the mathematical accuracy for each of management’s fair value estimates.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Tanger Factory Outlet Centers, Inc.  and subsidiaries (the “Company”) as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2019, of the Company and our report dated February 19, 2020, expressed an unqualified opinion on those financial statements and included an explanatory paragraph regarding the Company’s adoption of a new accounting standard.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS OF

TANGER FACTORY OUTLET CENTERS, INC. AND

TANGER PROPERTIES LIMITED PARTNERSHIP

1. 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 Tanger Properties Limited Partnership and subsidiaries, which we refer to as the Operating Partnership, focuses exclusively on developing, acquiring, owning, operating and managing outlet shopping centers. As of December 31, 2019, we owned and operated 32 consolidated outlet centers, with a total gross leasable area of approximately 12.0 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 97% occupied and contained over 2,400 stores, representing approximately 400 store brands. We also had partial ownership interests in 7 unconsolidated outlet centers totaling approximately 2.2 million square feet, including 3 outlet centers in Canada.

Our outlet centers and other assets are held by, and all of our operations are conducted by 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, 2019, the Company, through its ownership of Tanger GP Trust and Tanger LP Trust, owned 92,892,260 units of the Operating Partnership and other limited partners (the "Non-Company LPs") collectively owned 4,911,173 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.

2. Summary of Significant Accounting Policies

Reclassifications- Certain prior period balances in the accompanying consolidated statements of operations have been reclassified or combined to conform to the current period presentation. See Note 6 and Note 21 for additional details on the amounts reclassified.

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.

F-18

We consolidate properties that are wholly-owned or properties where we own less than 100% but control such properties. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities ("VIE"). For joint ventures that are determined to be a VIE, we consolidate the entity where we are deemed to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance, and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. Our determination of the primary beneficiary considers 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. As of December 31, 2019, we did not have a joint venture that was a VIE.

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.

The carrying amount of our investments in the Charlotte, Columbus, Galveston/Houston and National Harbor joint ventures are less than zero because of financing or operating distributions that were greater than net income, as net income includes non-cash charges for depreciation and amortization.

Noncontrolling interests - In the 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 or losses are 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.

F-19

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, 2019, 2018 and 2017 were as follows (in thousands):

	2019		2018		2017
Payroll and related costs capitalized	$	1,581	$	1,521	$	2,345
Interest costs capitalized	$	25	$	93	$	2,289

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, 2019, 2018 and 2017 was as follows (in thousands):

	2019		2018		2017
Depreciation expense related to rental property	$	107,129	$	114,198	$	107,845

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 are 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.

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.

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 internal leasing costs for the years ended December 31, 2019, 2018 and 2017 were as follows (in thousands):

	2019		2018		2017
Deferred lease costs capitalized- payroll and related costs	$	679	$	6,007	$	6,098
Total deferred lease costs capitalized	$	5,142	$	6,703	$	6,584

Due to the adoption of Accounting Standards Codification Topic 842 "Leases" ("ASC 842") on January 1, 2019, only direct internal leasing costs are capitalized and indirect internal leasing costs previously capitalized are now expensed. 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.

F-21

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. The cash flow estimates used both for determining recoverability and estimating fair value are inherently judgmental and reflect current and projected trends in rental, occupancy, capitalization, and discount rates, and estimated holding periods for the applicable assets. The estimated fair value is based primarily on the income approach. The income approach involves discounting the estimated income stream and reversion (presumed sale) value of a property over an estimated holding period to a present value at a risk-adjusted rate. Discount rates and terminal capitalization rates utilized in this approach are derived from property-specific information, market transactions and other financial and industry data.

During the fourth quarter of 2019 and third quarter 2018, we recorded a $37.6 million and $49.7 million, respectively, impairment charge in our consolidated statement of operations which equaled the excess of the carrying value of our Jeffersonville outlet center over its estimated fair value. See Note 11 for additional information on the fair market value calculation. We recognized no impairment losses for our consolidated properties during the year ended December 31, 2017. See Note 6 for discussion of the impairment of our unconsolidated joint ventures at the Bromont, Quebec and Saint Sauveur, Quebec outlet centers during the years ended December 31, 2018 and 2017.

In addition, based upon current market conditions, one of our outlet centers has an estimated fair value significantly less than its recorded carrying value of approximately $100.0 million. However, based on our current plan with respect to that outlet center, we believe that its carrying amount is recoverable and therefore no impairment charge was recorded. Accordingly, we will continue to monitor circumstances and events in future periods that could affect inputs such as the expected holding period, operating cash flow forecasts and capitalization rates, utilized to determine whether an impairment charge is necessary.  As these inputs are difficult to predict and are subject to future events that may alter our assumptions, the future cash flows estimated by management in its impairment analysis may not be achieved, and actual losses or impairment may be realized in the future.

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 or if circumstances exist, 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 an other than temporary 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 of real estate where we have consideration to which we are entitled in exchange for transferring the real estate, the related assets and liabilities are removed from the balance sheet and the resultant gain or loss is recorded in the period the transaction closes. Any post sale involvement is accounted for as a separate performance obligations and when the separate performance obligations are satisfied, the sales price allocated to each is recognized.

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.

F-22

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 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.

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 2016 - 2019 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 it is not probable that 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, 2019, 2018 and 2017 were taxable as follows:

Common dividends per share:	2019		2018		2017
Ordinary income	$	1.3261	$	1.3919	$	1.1660

Revenue Recognition - As a lessor, substantially all of our revenues are earned from arrangements that are within the scope of ASC 842. We utilized the practical expedient in ASU 2018-11 to account for lease and non-lease components as a single component which resulted in all of our revenues associated with leases being recorded as rental revenues in the consolidated statements of operations. Base rentals are recognized on a straight-line basis over the term of the lease. Tenant expense reimbursements are recognized in the period the applicable expenses are incurred. As a result of combining all components of a lease, all fixed contractual payments, including consideration received from certain executory costs, are now recognized on a straight-line basis. Straight-line rent adjustments recorded as a receivable in other assets on the consolidated balance sheets were approximately $61.6 million and $57.5 million as of December 31, 2019 and 2018, respectively. Common area maintenance expense reimbursements are based on the tenant's proportionate share of the allocable operating expenses for the property. 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. The majority of our 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. 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. Expense reimbursements from unconsolidated joint ventures are recognized in the period the applicable expenses are incurred.

Uncollectible Tenant Revenues - Due to the adoption of ASC 842 effective January 1, 2019, uncollectible tenant revenues were recorded as a contra-revenue adjustment in 2019. If it is determined collection is not probable we record revenues on a cash basis. Previously in 2018 and 2017, these adjustments were recorded in general and administrative expense.

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 2019, 2018 or 2017.

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, 2019, 2018 and 2017 (in thousands):

	2019		2018		2017
Costs relating to construction included in accounts payable and accrued expenses	$	17,619	$	15,772	$	32,060

Interest paid, net of interest capitalized was as follows for the years ended December 31, 2019, 2018 and 2017 (in thousands):

	2019		2018		2017
Interest paid, net of interest capitalized	$	57,237	$	60,529	$	56,730

Information related to non-cash assets and liabilities recorded as a result of the adoption of ASC 842 in 2019 was as follows (in thousands):

	2019
Non-Cash operating lease right-of-use assets exchanged for operating lease liabilities	$	87,679
Non-Cash operating lease liabilities exchanged for operating right-of-use assets	$	92,354

The difference between the recorded operating lease liabilities and operating right-of-use assets represents the accrued straight-line rent liability of $5.0 million and our prepaid rent balances of $307,000 previously recognized under Accounting Standards Codification Topic 840 “Leases” (“ASC 840”) that were reclassified to the operating leases right-of use assets under ASC 842. 

Accounting for Equity-Based Compensation - We have a shareholder approved equity-based compensation plan, the Incentive Award Plan of Tanger Factory Outlet Centers, Inc. 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 and we estimate expected forfeitures in determining compensation cost.

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.

Recently adopted accounting standards (other than ASC 842 Leases, see Note 21)

In October 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2018-16, Inclusion of the Secured Overnight Financing Rate (“SOFR”) Overnight Index Swap (“OIS”) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes to Accounting Standards Codification 815. ASU 2018-16 expands the list of U.S. benchmark interest rates permitted in the application of hedge accounting by adding the OIS rate based on SOFR as an eligible benchmark interest rate. The mandatory effective date for calendar year-end public companies was January 1, 2019. The adoption of ASU 2018-16 as of January 1, 2019 did not have a material impact on our consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. ASU 2018-07 amends prior employee share-based payment guidance to include nonemployee share-based payment transactions for acquiring services or property. This ASU now aligns the determination of the measurement date, the accounting for performance conditions, and the accounting for share-based payments after vesting in addition to other items. The provisions of ASU 2018-07 were effective for us as of January 1, 2019 using a modified transition method upon adoption, and early adoption was permitted. The adoption of ASU 2018-07 as of January 1, 2019 did not have a material impact on our consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. The new guidance made more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amended the presentation and disclosure requirements and changed how companies assess effectiveness. It is intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The adoption of ASU 2017-12 as of January 1, 2019 did not have a material impact on our consolidated financial statements.

F-25

Recently issued accounting standards to be adopted

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 is intended to improve the effectiveness of disclosures required by entities regarding recurring and nonrecurring fair value measurements. ASU 2018-13 is effective for reporting periods beginning after December 15, 2019, with early adoption permitted. The adoption of ASU 2018-13 will not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13 to amend the accounting for credit losses for certain financial instruments. Under the new guidance, an entity recognizes its estimate of expected credit losses as an allowance, which the FASB believes will result in more timely recognition of such losses. In November 2018, the FASB released ASU No. 2018-19 “Codification Improvements to Topic 326, Financial Instruments - Credit Losses.” This ASU clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20 “Financial Instruments - Credit Losses.” Instead, impairment of receivables arising from operating leases should be accounted for under Subtopic 842-30 “Leases - Lessor.” ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The adoption of this new guidance will not have a material impact on our consolidated financial statements.

3.    Acquisition of Rental Property

2017 Acquisition

Foxwoods

In November 2017, we successfully settled litigation with the estate of our former partner in the Foxwoods, Connecticut joint venture.  In return for mutual releases and no cash consideration, the estate tendered its partnership interest to the Company. Prior to this settlement, we had a 100% economic interest in the consolidated joint venture as a result of our preferred equity interest and the capital and distribution provisions in the joint venture agreement.

4. Disposition of Properties

The following table sets forth the properties sold for the years ended 2019 and 2017 (in thousands). No properties were sold during 2018.

Lancaster Expansion

In September 2017, we opened a 123,000 square foot expansion of our outlet center in Lancaster, Pennsylvania.

6. 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, 2019

					$	(32.5	)

(1) Net of debt origination costs and including premiums of $1.1 million and $1.4 million as of December 31, 2019 and 2018, respectively.

(2) 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 and intend to provide further financial support to these joint ventures. 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 and equity in earnings of the joint ventures.

F-27

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,
	2019		2018		2017
Fees:
Management and marketing	$	2,308	$	2,334	$	2,310
Leasing and other fees	126		162		142
Expense reimbursements from unconsolidated joint ventures	2,985		2,499		1,212
Total Fees	$	5,419	$	4,995	$	3,664

Expense reimbursements from unconsolidated joint ventures were previously included in expense reimbursements in our Form 10-K for the year ended December 31, 2018. As these revenues are not related to leases, the 2018 amounts have been reclassified to management, leasing and other services on the consolidated statements of operations to conform to the current year presentation. See Note 21 for discussion of adoption of ASC 842.

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 $3.8 million and $4.1 million as of December 31, 2019 and 2018, 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. In June 2018, the Charlotte joint venture closed on a $100.0 million mortgage loan with a fixed interest rate of approximately 4.3% and a maturity date of July 2028. The proceeds from the loan were used to pay off the existing $90.0 million mortgage loan with an interest rate of LIBOR + 1.45%, which had an original maturity date of November 2018. The joint venture distributed the incremental net loan proceeds of $9.3 million equally to the partners. Our partner is providing property management, marketing and leasing services to the joint venture.

Columbus

In June 2016, we opened an approximately 355,000 square foot outlet center in Columbus, Ohio. The development was initially fully funded with equity contributed to the joint venture by Tanger and its partner. 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 matured 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. In October 2019, the joint venture exercised its first option to extend the mortgage loan for one year to November 2020 under the same terms. We are providing property management, marketing and leasing services to the joint venture.

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. In July 2017, the joint venture amended and restated the initial construction loan, which had an outstanding balance of $65.0 million, to increase the amount available to borrow from $70.0 million to $80.0 million and extended the maturity date until July 2020 with two one-year options. The amended and restated loan also changed the interest rate from LIBOR + 1.50% to LIBOR + 1.65%. At the closing of the amendment, the joint venture distributed the net proceeds of approximately $14.5 million equally between the partners. We are providing property management, marketing and leasing services to the outlet center.

F-28

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 December 2018, the National Harbor joint venture closed on a $95.0 million mortgage loan with a fixed interest rate of approximately 4.6% and a maturity date of January 2030. The proceeds from the loan were used to pay off the $87.0 million construction loan with an interest rate of LIBOR + 1.65%, which had an original maturity date of November 2019. The joint venture distributed the incremental net loan proceeds of $7.4 million equally to the partners.

RioCan Canada

We have a 50/50 co-ownership agreement with RioCan Real Estate Investment Trust to operate and manage outlet centers in Canada. We provide leasing and marketing services for the outlet centers and RioCan provides 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 2016, the co-owners commenced construction on a 39,000 square foot expansion, which opened during the second quarter of 2017 to bring the total square feet of the outlet center to approximately 357,000.

Other properties owned by the RioCan Canada co-owners include Cookstown Outlet Mall and Les Factoreries Saint-Sauveur. Cookstown Outlet Mall is approximately 308,000 square feet and Les Factoreries Saint-Sauveur is approximately 116,000 square feet.

In May 2019, the RioCan joint venture closed on the sale of its 161,000 square foot outlet center in Bromont, for net proceeds of approximately $6.4 million. Our share of the proceeds was approximately $3.2 million. As a result of this transaction, we recorded a foreign currency loss of approximately $3.6 million in other income (expense), which had been previously recorded in other comprehensive income.

During 2018 and 2017, the Rio-Can joint venture recognized impairment charges related to its Bromont and Saint Sauveur properties. The impairment charges were primarily driven by, among other things, new competition in the market and changes in market capitalization rates.

The table below summarizes the impairment charges taken during 2018 and 2017 (in thousands):

		Impairment Charge(1)
	Outlet Center	Total		Our Share
2018	Bromont and Saint Sauveur	$	14,359	$	7,180
2017	Bromont and Saint Sauveur	$	18,042	$	9,021

(1) The fair value was determined using an income approach considering the prevailing market income capitalization rates for similar assets.

The syndicated line may be increased up to $1.2 billion through an accordion feature in certain circumstances. As of December 31, 2019, letters of credit totaling $170,000 were issued under the lines of credit.

The unsecured lines of credit and senior unsecured notes include covenants that require the maintenance of certain ratios, including debt service coverage and leverage, and limit the payment of dividends such that dividends and distributions will not exceed funds from operations, as defined in the agreements, for the prior fiscal year on an annual basis or 95% of funds from operations on a cumulative basis. As of December 31, 2019, we believe we were in compliance with all of our debt covenants.

2018 Transactions

Increased Borrowing Capacity and Extension of Unsecured Lines of Credit

In January 2018, we closed on amendments to our unsecured lines of credit, which increased the borrowing capacity from $520.0 million to $600.0 million and extended the maturity date from October 2019 to October 2021, with a one-year extension option. We also reduced the interest rate spread over LIBOR from 0.90% to 0.875%, and increased the incremental borrowing availability through an accordion feature on the syndicated line from $1.0 billion to $1.2 billion. Loan origination costs associated with the amendments totaled approximately $2.3 million.

Southaven Mortgage

In February 2018, the consolidated joint venture that owns the Tanger outlet center in Southaven, Mississippi amended and restated the $60.0 million mortgage loan secured by the property that was scheduled to mature in April 2018. The amended and restated loan reduced the principal balance to $51.4 million, increased the interest rate from LIBOR + 1.75% to LIBOR + 1.80% and extended the maturity to April 2021, with a two-year extension option. In March 2018, the consolidated joint venture entered into an interest rate swap, effective March 1, 2018, that fixed the base LIBOR rate at 2.47% on a notional amount of $40.0 million through January 31, 2021.

Unsecured Term Loan

In October 2018, we amended and restated our unsecured term loan, increasing the size of the loan from $325.0 million to $350.0 million, extending the maturity from April 2021 to April 2024, and reducing the interest rate spread over LIBOR from 0.95% to 0.90%. The $25.0 million of proceeds were used to pay down the balances outstanding under our unsecured lines of credit.

2017 Transactions

$300.0 Million Unsecured Senior Notes due 2027

In July 2017, we completed an underwritten public offering of $300.0 million of 3.875% senior notes due 2027 (the "2027 Notes"). The 2027 Notes priced at 99.579% of the principal amount to yield 3.926% to maturity. The 2027 Notes pay interest semi-annually at a rate of 3.875% per annum and mature on July 15, 2027. The net proceeds from the offering, after deducting the underwriting discount and offering expenses, were approximately $295.9 million. In August 2017, we used the net proceeds from the sale of the 2027 Notes, together with borrowings under our unsecured lines of credit, to redeem all of our 6.125% senior notes due 2020 (the "2020 Notes") (approximately $300.0 million in aggregate principal amount outstanding). The 2020 Notes were redeemed at par plus a “make-whole” premium of approximately $34.1 million. In addition, we wrote off approximately $1.5 million of unamortized debt discount and debt origination costs related to the 2020 Notes.

Foxwoods Debt Repayment

In November 2017, we repaid the $70.3 million floating rate mortgage loan secured by the Foxwoods property with borrowings under its unsecured floating rate lines of credit.

(1) Asset balances are recorded in prepaids and other assets on the consolidated balance sheets and liabilities are recorded in other liabilities on the consolidated balance sheets.

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.

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.

11.    Fair Value Measurements

Fair value guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers are defined as follows:

Tier	Description
Level 1	Observable inputs such as quoted prices in active markets
Level 2	Inputs other than quoted prices in active markets that are either directly or indirectly observable
Level 3	Unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions

Fair Value Measurements on a Recurring Basis

The following table sets forth our assets and liabilities that are measured at fair value within the fair value hierarchy (in thousands):

			Level 1		Level 2		Level 3
			Quoted Prices in Active Markets for Identical Assets or Liabilities		Significant Observable Inputs		Significant Unobservable Inputs
	Total
Fair value as of December 31, 2019:
Asset:
Interest rate swaps (prepaids and other assets)	$	1,018	$	—	$	1,018	$	—
Total assets	$	1,018	$	—	$	1,018	$	—
Liabilities:
Interest rate swaps (other liabilities)	$	1,442	$	—	$	1,442	$	—
Total liabilities	$	1,442	$	—	$	1,442	$	—

			Level 1		Level 2		Level 3
			Quoted Prices in Active Markets for Identical Assets or Liabilities		Significant Observable Inputs		Significant Unobservable Inputs
	Total
Fair value as of December 31, 2018:
Assets:
Interest rate swaps (prepaids and other assets)	$	5,755	$	—	$	5,755	$	—
Total assets	$	5,755	$	—	$	5,755	$	—
Liabilities:
Interest rate swaps (other liabilities)	$	6	$	—	$	6	$	—
Total liabilities	$	6	$	—	$	6	$	—

F-36

Fair values of interest rate swaps are approximated using Level 2 inputs based on current market data received from financial sources that trade such instruments and are based on prevailing market data and derived from third party proprietary models based on well recognized financial principles including counterparty risks, credit spreads and interest rate projections, as well as reasonable estimates about relevant future market conditions.

Fair Value Measurements on a Nonrecurring Basis

The following table sets forth our assets that are measured at fair value on a nonrecurring basis 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, 2019:
Asset:
Long-lived assets	$	10,000	$	—	$	—	$	10,000
Fair value as of September 30, 2018:
Asset:
Long-lived assets	$	50,000	$	—	$	—	$	50,000

During the third quarter 2018, we determined that the estimated future undiscounted cash flows of our Jeffersonville outlet center did not exceed the property's carrying value. This shortfall was due to an expected decline in operating results caused by anticipated store closures from bankruptcy filings and brand-wide restructurings and a shift in the local competitive environment. Accordingly we recorded a $49.7 million impairment charge in our consolidated statement of operations which equaled the excess of the carrying value of our Jeffersonville outlet center over its estimated fair value. The estimated fair value was based on the income approach. The income approach involves discounting the estimated income stream and reversion (presumed sale) value of a property over an estimated holding period to a present value at a risk-adjusted rate.

During the fourth quarter of 2019, in anticipation of further store closings and declining operating results, we recorded an additional impairment charge of $37.6 million in our consolidated statement of operations which equaled the excess of the carrying value of our Jeffersonville outlet center over its estimated fair value. The estimated fair value was based on the income approach.

Discount rates and terminal capitalization rates utilized in the approach above were derived from property-specific information, market transactions and other financial and industry data. The terminal capitalization rate and discount rate are significant unobservable inputs in determining the fair value. These inputs are classified under Level 3 in the fair value hierarchy above.

The table below summarizes the terminal capitalization rate and discount rate used:

	December 31, 2019		September 30, 2018
Terminal capitalization rate	12	%	10	%
Discount rate	13	%	10	%

F-37

Other Fair Value Disclosures

The estimated fair value and recorded value of our debt as of December 31, 2019 and 2018 were as follows (in thousands):

	2019		2018
Level 1 Quoted Prices in Active Markets for Identical Assets or Liabilities	$	—	$	—
Level 2 Significant Observable Inputs	1,169,481		1,085,138
Level 3 Significant Unobservable Inputs	434,333		583,337
Total fair value of debt	$	1,603,814	$	1,668,475
Recorded value of debt	$	1,569,773	$	1,712,918

Our senior unsecured notes are publicly-traded which provides quoted market rates. However, due to the limited trading volume of these notes, we have classified these instruments as Level 2 in the hierarchy. Our other debt is classified as Level 3 given the unobservable inputs utilized in the valuation. Our unsecured term loan, unsecured lines of credit and variable interest rate mortgages are all LIBOR based instruments. When selecting the discount rates for purposes of estimating the fair value of these instruments, we evaluated the original credit spreads and do not believe that the use of them differs materially from current credit spreads for similar instruments and therefore the recorded values of these debt instruments is considered their fair value.

The carrying values of cash and cash equivalents, receivables, accounts payable, accrued expenses and other assets and liabilities are reasonable estimates of their fair values because of the short maturities of these instruments.

12.    Shareholders' Equity of the Company

As discussed in Note 14, each Class A common limited partnership unit is exchangeable for one common share of the Company. The following table sets forth the number of Class A common limited partnership units exchanged for an equal number of common shares for the years ended December 31, 2019, 2018 and 2017:

Share Repurchase Program

In May 2017, the Company announced that our Board of Directors authorized the repurchase of up to $125.0 million of its outstanding common shares as market conditions warrant over a period commencing on May 19, 2017 and expiring on May 18, 2019.  In February 2019, the Company’s Board of Directors authorized the repurchase of an additional $44.3 million of our outstanding common shares for an aggregate authorization of $169.3 million until May 2021. Repurchases may be made from time to time through open market, privately-negotiated, structured or derivative transactions (including accelerated share repurchase transactions), or other methods of acquiring shares. The Company intends to structure open market purchases to occur within pricing and volume requirements of Rule 10b-18.  The Company may, from time to time, enter into Rule 10b5-1 plans to facilitate the repurchase of its shares under this authorization.

F-38

Shares repurchased during the years ended December 31, 2019, 2018 and 2017 were as follows:

	Year Ended December 31,

The remaining amount authorized to be repurchased under the program as of December 31, 2019 was approximately $80.0 million.

13.    Partners' Equity of the Operating Partnership

All units of partnership interest issued by the Operating Partnership have equal rights with respect to earnings, dividends and net assets. When the Company issues common shares upon the exercise of options, the issuance of restricted share awards or the exchange of Class A common limited partnership units, the Operating Partnership issues a corresponding Class B common limited partnership unit to Tanger LP Trust, a wholly-owned subsidiary of the Company. Likewise, when the Company repurchases its outstanding common shares, the Operating Partnership repurchases corresponding Class B common limited partnership units held by Tanger LP Trust.

The following table sets forth the changes in outstanding partnership units for the years ended December 31, 2019, 2018 and 2017:

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 2019 and 2018, 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, 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, and units repurchased by the Operating Partnership as a result of the Company's repurchase of its outstanding common shares. As discussed in Note 13, for the years ended December 31, 2019 and 2018, Non-Company LPs exchanged 49,511 and 34,749 Class A common limited partnership units of the Operating Partnership, respectively, for an equal number of common shares of the Company. In addition, for the years ended December 31, 2019 and 2018, the Company repurchased approximately 1,209,328 and 919,249 common shares, respectively, on the open market and the Operating Partnership repurchased an equal number of units held by the Company.

The changes in the Company's ownership interests in the subsidiaries impacted consolidated equity during the periods shown as follows (in thousands):

	2019		2018
Net income attributable to Tanger Factory Outlet Centers, Inc.	$	87,855	$	43,655

15.    Earnings Per Share of the Company

The following table sets forth a reconciliation of the numerators and denominators in computing earnings per share for the years ended December 31, 2019, 2018 and 2017 (in thousands, except per share amounts):

	2019			2018			2017

Effect of outstanding options and certain restricted common shares	—			1			16
Diluted weighted average common shares	92,808			93,310			94,522
Basic earnings per common share:
Net income	$	0.93		$	0.45		$	0.71
Diluted earnings per common share:
Net income	$	0.93		$	0.45		$	0.71

We determine diluted earnings per share based on the weighted average number of common shares outstanding combined with the incremental weighted average shares that would have been outstanding assuming all potentially dilutive securities were converted into common shares at the earliest date possible. There were no material securities which had a dilutive effect on earnings per common share for the years ended December 31, 2019 and 2018.

Notional units granted under our equity compensation plan are considered contingently issuable common shares and are included in earnings per share if the effect is dilutive using the treasury stock method and the common shares would be issuable if the end of the reporting period were the end of the contingency period. For the years ended December 31, 2019, 2018, and 2017, approximately 1.1 million, 1.0 million and 603,000 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 or because they were anti-dilutive.

With respect to outstanding options, the effect of dilutive common shares is determined using the treasury stock method whereby outstanding options are assumed exercised at the beginning of the reporting period and the exercise proceeds from such options and the average measured but unrecognized compensation cost during the period are assumed to be used to repurchase our common shares at the average market price during the period. For the years ended December 31, 2019, 2018 and 2017, approximately 523,000, 535,000 and 169,000 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.

Net income	$	0.93		$	0.45		$	0.71
Diluted earnings per common unit:

We determine diluted earnings per unit based on the weighted average number of common units outstanding combined with the incremental weighted average units that would have been outstanding assuming all potentially dilutive securities were converted into common units at the earliest date possible. There were no material securities which had a dilutive effect on earnings per common share for the years ended December 31, 2019 and 2018.

Notional units granted under our equity compensation plan are considered contingently issuable common units and are included in earnings per unit if the effect is dilutive using the treasury stock method and the common units would be issuable if the end of the reporting period were the end of the contingency period. For the years ended December 31, 2019, 2018, and 2017, approximately 1.1 million, 1.0 million and 603,000 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 or because they were anti-dilutive. The notional units are considered contingently issuable common units and are included in earnings per unit if the effect is dilutive using the treasury stock method.

With respect to outstanding options, the effect of dilutive common units 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 units at the average market price during the period. The market price of a common unit is considered to be equivalent to the market price of a Company common share. For the years ended December 31, 2019, 2018 and 2017, approximately 523,000, 535,000 and 169,000 options were excluded from the computation, respectively.

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.

17.    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.

As of December 31, 2019, we may issue up to 18.7 million common shares under the Plan. Shares remaining available for future issuance totaled approximately 3,854,000 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, 2019, 2018 and 2017, respectively, as follows (in thousands):

	2019		2018		2017
Restricted common shares	$	12,036	$	9,870	$	9,395
Notional unit performance awards	5,918		4,356		3,913
Options	166		443		277
Total equity-based compensation	$	18,120	$	14,669	$	13,585

Equity-based compensation expense capitalized as a part of rental property and deferred lease costs were as follows (in thousands):

	2019		2018		2017
Equity-based compensation expense capitalized	$	384	$	1,131	$	1,044

As of December 31, 2019, there was $15.3 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 2.4 years.

Restricted Common Share and Restricted Share Unit Awards

During 2019, 2018 and 2017, the Company granted approximately 309,000, 407,000 and 253,000 restricted common shares and restricted share units, respectively, to the Company's non-employee directors and the Company's senior executive officers. The non-employee directors' restricted common shares generally vest ratably over a three year period and the senior executive officers' restricted common shares (other than our Chief Executive Officer's) generally vest ratably over periods ranging from three to five years. For the restricted common shares and restricted share units issued to our chief executive officer during 2019, 2018 and 2017, the award agreements generally require him to hold the shares or units issued to him for a minimum of three years following each applicable vesting date or the share issuance date, as applicable. Compensation expense related to the amortization of the deferred compensation is being recognized in accordance with the vesting schedule of the restricted common shares and restricted share units. For all of the restricted common share and restricted share unit awards described above, the grant date fair value of the awards were determined based upon the closing market price of the Company's common shares on the day prior to the grant date.

F-43

The following table summarizes information related to unvested restricted common shares and restricted share units outstanding for the years ended December 31, 2019, 2018, and 2017:

(1) Includes 44,452 restricted share units.

(2) Includes 51,217 restricted share units.

The table above excludes restricted common shares earned under the 2014 Outperformance Plan. In connection with the 2014 Outperformance Plan, we issued approximately 184,000 restricted common shares in January 2017, with approximately 94,000 vesting immediately and the remaining 90,000 vesting in January 2018, contingent upon continued employment with the Company through the vesting date (unless terminated prior thereto (a) by the Company without cause, (b) by participant for good reason or (c) due to death or disability).

The total value of restricted common shares vested during the years ended 2019, 2018 and 2017 was $9.2 million, $9.2 million and $12.4 million, respectively. During 2019, 2018 and 2017, we withheld shares with value equivalent to the employees' 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 approximately 132,000, 89,000 and 70,000 for 2019, 2018 and 2017, 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 $2.5 million, $2.1 million and $2.4 million for 2019, 2018 and 2017, respectively, which are reflected as a financing activity within the consolidated statements of cash flows.

Notional Unit Performance Awards

Outperformance Plan

Each year, the Compensation Committee of Tanger Factory Outlet Centers, Inc. approves the terms and the number of awards to be granted under the Tanger Factory Outlet Centers, Inc. Outperformance Plan (the “OPP"). The OPP is a long-term 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 absolute total shareholder return) and its share price appreciation relative to its peer group (or relative total shareholder return) over a three-year measurement period. For all recipients (other than our chief executive officer), any shares earned at the end of the three-year measurement period are subject to a time-based vesting schedule, with 50% of the shares vesting immediately following the measurement period, and the remaining 50% vesting one year thereafter, contingent upon continued employment with the Company through the vesting date (unless terminated prior thereto (a) by the Company without cause, (b) by participant for good reason or (c) due to death or disability. For our chief executive officer, any shares earned at the end of the three-year measurement period remain subject to a time-based vesting schedule and are issued following vesting, with 50% of the shares vesting immediately following issuance, 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 due to retirement or (c) due to death or disability).

The following table sets forth OPP performance targets and other relevant information about each plan:

(1) The number of restricted common shares received under the 2019 and 2018 OPP will be determined on a pro-rata basis by linear interpolation between total shareholder return thresholds, both for absolute total shareholder return and for relative total shareholder return amongst the Company's peer group. The peer group is based on companies included in the FTSE NAREIT Retail Index.

(2) The performance shares for the 2017 OPP will convert on a pro-rata basis by linear interpolation between share price appreciation thresholds, both for absolute total shareholder return and for relative total shareholder return. The share price for the purposes of calculation of share price appreciation will be adjusted on a penny-for-penny basis with respect to any dividend payments made during the measurement period. The peer group is based on companies included in the SNL Equity REIT index.

(3) On February 15, 2019, the measurement period for the 2016 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 2016 OPP performance awards were automatically forfeited.

(4) On December 31, 2017, the measurement period for the 2015 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 2015 OPP performance awards were automatically forfeited.

F-45

The fair values of the OPP awards granted during the years ended December 31, 2019, 2018, and 2017 were determined at the grant dates using a Monte Carlo simulation pricing model and the following assumptions:

	2019		2018		2017
Risk free interest rate (1)	2.55	%	2.40	%	1.52	%
Expected dividend yield (2)	5.3	%	4.8	%	3.4	%
Expected volatility (3)	24	%	27	%	19	%

(1) Represents the interest rate as of the grant date on U.S. 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, 2019, 2018, and 2017:

During February 2018, the Company granted 331,000 options to non-executive employees of the Company. The exercise price of the options granted during the first quarter of 2018 was $21.94 per share 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, which resulted in a weighted average grant date fair value per share of $3.62 and included the following weighted-average assumptions: expected dividend yield 6.24%; expected life of 7.1 years; expected volatility of 32.47%; a risk-free rate of 2.8%; and forfeiture rates of 3.0% to 10.0% dependent upon the employee's position within the Company. The total intrinsic value of options exercised during the year ended December 31, 2017 was $8,000. For both the years ended December 31, 2019 and 2018, no options were exercised.

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, 2019, 2018 and 2017, we contributed approximately $889,000, $872,000 and $862,000, respectively, to the 401(k) Retirement Savings Plan.

21.    Lease Agreements

On January 1, 2019, we adopted ASC 842, which supersedes ASC 840. We adopted ASC 842 using the modified retrospective approach, whereby there was no cumulative effect adjustments to retained earnings on adoption and prior periods were not restated. Accordingly, our leases and lease related costs, as both lessee and lessor, and lease related receivables, as lessor, are presented under ASC 842 for the year ended December 31, 2019 and under ASC 840 the year ended December 31, 2018.

As a lessor, substantially all of our revenues are earned from arrangements that are within the scope of ASC 842. We utilized the practical expedient in ASU 2018-11 to account for lease and non-lease components as a single component which resulted in all of our revenues associated with leases being recorded as rental revenues in the consolidated statements of operations. As a result of the adoption of ASC 842, the amounts disclosed in our Annual Report on Form 10-K for the year ended December 31, 2018 as base rentals, percentage rentals and expense reimbursements have now been combined into rental revenues on the consolidated statements of operations to conform to the current year presentation. In addition, certain amounts previously included in expense reimbursements in our Annual Report on Form10-K for the year ended December 31, 2018, which are not related to leases have been reclassified to management, leasing and other services and other revenues on the consolidated statements of operations to conform to the current year presentation. See Note 6 for additional details on the amounts reclassified to management, leasing and other services.

ASC 842 requires certain other accounting changes effective January 1, 2019 where prior year amounts are not reclassified or restated. Uncollectible tenant revenues previously recorded in general and administrative expense are recorded in rental revenues as a contra-revenue account in 2019. As a result of combining all components of a lease, all fixed contractual payments, including consideration received from certain executory costs, are now recognized on a straight-line basis. For the year ended December 31, 2019, we recorded a straight-line rent adjustment of $6.4 million in rental revenues in our consolidated statements of operations to record revenues from executory costs on a straight-line basis. In addition, direct internal leasing costs are capitalized, however, indirect internal leasing costs previously capitalized are now expensed. We only capitalize the portion of these types of costs incurred that are a direct result of an executed lease. For the year ended December 31, 2019, lease costs of approximately $4.9 million were expensed which would have been capitalized under ASC 840.

As a lessee, the new standard also provides a number of optional provisions, known as practical expedients, which companies may elect to adopt to facilitate implementation. We elected the package of practical expedients which, among other items, precludes us from needing to reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification of any expired or existing leases, and (3) initial direct costs for any existing leases.

Information as Lessor Under ASC 842

As of December 31, 2019, we were the lessor to over 2,400 stores in our 32 consolidated outlet centers, under operating leases with initial terms that expire from 2020 to 2035, with certain agreements containing extension options. We also have certain agreements which require tenants to pay their portion of reimbursable expenses such as common area expenses, utilities, insurance and real estate taxes.

For the year ended December 31, 2019, the components of rental revenues are as follows (in thousands):

	2019
Rental revenues - fixed	$	360,513
Rental revenues - variable (1)	103,433
Rental revenues	$	463,946

(1) Primarily includes rents based on a percentage of tenant sales volume and reimbursable expenses such as common area expenses, utilities, insurance and real estate taxes.

Information as Lessor Under ASC 840

As of December 31, 2018, we were the lessor to over 2,600 stores in our 36 consolidated outlet centers, under operating leases with initial terms that expire from 2019 to 2033. The majority of our leases contain provisions which provide additional rents based on tenants’ sales volume. Percentage rentals are recognized when specified targets that trigger the contingent rent are met.

Future minimum lease receipts under non-cancelable operating leases as of December 31, 2018, excluding the effect of straight-line rent and variable rentals, are as follows (in thousands):

Information as Lessee Under ASC 842

Adoption of the new standard resulted in the recording of operating lease right-of-use assets and operating lease liabilities, of $90.4 million and $95.1 million, respectively, as of January 1, 2019 equal to the present value of the minimum lease payments required under each lease. The difference between the recorded operating lease liability and operating right-of-use assets represents the accrued straight-line rent liability and our prepaid rent balances previously recognized under ASC 840.  In March 2019, we sold our Ocean City outlet center, which had an operating lease right-of-use asset and operating lease liability of approximately $2.5 million.

Our non-cancelable operating leases, with terms in excess of one year, have terms, including certain extension options, that expire from 2028 to 2101. Certain extension options, which are reasonably certain at inception, are used in the calculation of our operating lease right-of-use assets based on the economic life of the asset. Leases with an initial term of 12 months or less (short-term leases) are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. The majority of our operating lease expense is related to ground leases at the following outlet centers: Myrtle Beach Hwy 17, Atlantic City, Sevierville, Riverhead, Foxwoods and Rehoboth Beach and the lease of our corporate office in Greensboro, North Carolina.

F-51

For the year ended December 31, 2019, the components of lease costs are as follows (in thousands):

	2019
Operating lease costs	$	5,519
Short-term lease costs	2,297
Variable lease costs (1)	231
Total lease costs	$	8,047

(1) Our variable lease costs relate to our ground leases where increases in payments are based on center financial performance.

The discount rate applied to measure each operating lease right-of-use asset and operating lease liability is based on our incremental borrowing rate (“IBR”). We consider the general economic environment and our credit rating and factor in various financing and asset specific adjustments to ensure the IBR is appropriate based on the intended use of the underlying lease. The lease term and discount rates are as follows:

	2019
Weighted - average remaining lease term (years)	50
Weighted - average discount rate	5.0	%

Cash flow information related to leases for the year ended December 31, 2019 was as follows (in thousands):

Information as Lessee Under ASC 840

As of December 31, 2018, our non-cancelable operating leases have terms, including certain extension options, that expire from 2019 to 2101. Rental payments for these leases totaled approximately $7.2 million and $7.1 million, for the years ended December 31, 2018 and 2017, respectively. As of December 31, 2018, the majority of our rental payments are related to ground leases at the following outlet centers: Myrtle Beach Hwy 17, Atlantic City, Ocean City, Sevierville, Riverhead, Foxwoods and Rehoboth Beach and the lease of our corporate office in Greensboro, North Carolina. The contingent portion of our ground lease payments is based on center performance and/or changes in an index.

22.    Commitments and Contingencies

Commitments and Contingencies of Consolidated Properties

Capital expenditure commitments

Commitments to complete construction of our ongoing capital projects and other capital expenditure requirements amounted to approximately $17.7 million at December 31, 2019.

Litigation

We are also subject to legal proceedings and claims, which arise from time to time in the ordinary course of our business and have not been finally adjudicated. In our opinion, the ultimate resolution of these matters is not expected to have a material effect on our consolidated financial statements. We record a liability in our consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. We review these estimates each accounting period as additional information is known and adjust the loss provision when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, we estimate and disclose the possible loss or range of loss to the extent necessary to make the consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in our consolidated financial statements.

Employment Agreements

We are party to employment agreements with certain executives that provide for compensation and certain other benefits. The agreements also provide for severance payments under certain circumstances.

Commitments and Contingencies of Unconsolidated Properties

Capital expenditure commitments

Contractual commitments for ongoing capital projects and other capital expenditure requirements related to our unconsolidated joint ventures amounted to approximately $1.0 million at December 31, 2019, of which our portion was approximately $481,000. Contractual commitments represent only those costs subject to contracts which are legal binding agreements as of December 31, 2019 and do not necessary represent the total cost to complete the projects.

F-53

Debt

We provide guarantees to lenders for our joint ventures which include standard non-recourse carve out indemnifications for losses arising from items such as but not limited to fraud, physical waste, payment of taxes, environmental indemnities, misapplication of insurance proceeds or security deposits and failure to maintain required insurance. For construction and mortgage loans, we may include a guaranty of completion as well as a principal guaranty ranging from 5% to 100% of principal.  The principal guarantees include terms for release based upon satisfactory completion of construction and performance targets including occupancy thresholds and minimum debt service coverage tests. Our joint ventures may contain make whole provisions in the event that demands are made on any existing guarantees. As of December 31, 2019, the maximum amount of joint venture debt guaranteed by the Company is $19.4 million.

EXHIBIT 4.2

DESCRIPTION OF COMMON SHARES

Tanger Factory Outlet Centers, Inc. (the “Company”) has authority to issue 300,000,000 common shares, $0.01 par value per share.

General

The following description of our common shares sets forth certain general terms and provisions of our common shares. The statements below describing our common shares are in all respects subject to and qualified in their entirety by reference to the applicable provisions of our Amended and Restated Articles of Incorporation, as amended (“charter”), and bylaws.

Terms

Each of our outstanding common shares is be entitled to one vote on all matters presented to shareholders for a vote. Holders of our common shares do not have, nor are subject to, any pre-emptive or similar rights.

Except for the election of a director to fill a vacancy on the board of directors, the election of directors by holders of one or more class or series of our preferred shares, or in the event of a contested election, directors are elected by the holders of our common shares at each annual meeting of shareholders by a majority of the votes cast. In the event of a contested election, directors are elected by a plurality of the votes cast by the shares entitled to vote in the election. Holders of our common shares do not have cumulative voting rights for the election of directors. A director may be removed by a majority of votes cast. If a director is elected by a voting group of shareholders, only the shareholders of that voting group may participate in a vote to remove him.

Dividends and other distributions may be paid to the holders of our common shares if and when declared by the board of directors of the Company out of funds legally available therefor.

Under North Carolina law, shareholders are generally not liable for our debts or obligations. Payment and declaration of dividends on our common shares and purchases of our shares are subject to certain limitations under North Carolina law and will be subject to certain restrictions if we fail to pay dividends on one or more series of our preferred shares. If we were to experience a liquidation, dissolution or winding up, each of our common shares would, subject to the rights of any holders of our preferred shares to receive preferential distributions, be entitled to participate equally in the assets available for distribution to them after payment of, or adequate provision for, all our known debts and liabilities.

Restrictions on Ownership and Transfer

For us to qualify as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”), not more than 50% in value of our outstanding capital stock may be owned, actually or constructively, by five or fewer individuals during the last half of our taxable year. This requirement is referred to as the “five or fewer” requirement. For purposes of this five or fewer requirement, individuals include the entities that are set forth in Section 542(a)(2) of the Code. Attribution rules in the Code determine if any individual or entity constructively owns our stock under the “five or fewer” requirement. Our capital stock also must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of 12 months, or during a proportionate part of a shorter taxable year. In addition, rent from a related party tenant is not qualifying income for purposes of the gross income tests under the Code. A related party tenant is generally a tenant in which the REIT or an owner of 10% or more of the REIT owns, actually or constructively, 10% or more of the equity interests, by vote or value. To assist us in meeting these requirements, we may take certain actions to limit the actual, beneficial or constructive ownership by a single person or entity of our outstanding equity securities.

Subject to certain exceptions specified in our charter, no shareholder (other than Stanley K. Tanger, our founder and the deceased father of Steven B. Tanger, Steven B. Tanger, members of their families, affiliated entities and their transferees) may own, or be deemed to own by virtue of the constructive ownership provisions of the Code, more than 4% of our outstanding common shares. Our charter provides that Stanley K. Tanger, Steven B. Tanger, members of their families, affiliated entities and their transferees may acquire additional common shares, but may not acquire additional shares, such that the five largest beneficial owners of our common shares, taking into account the 4% limit and certain exemptions from such limit that the board of directors has granted to other shareholders, could hold more than 49% of our outstanding common shares. The constructive ownership rules are complex and may cause common shares owned actually or constructively by a group of related individuals and/or entities to be constructively owned by one individual or entity. As a result, the acquisition of less than 4% of our outstanding common shares (or the acquisition of an interest in an entity which owns our common shares) by an individual or entity could cause that individual

or entity (or another individual or entity) to constructively own in excess of 4% of our outstanding common shares, and thus subject those common shares to the ownership limit in our charter.

If the board of directors shall at any time determine in good faith that a person intends to acquire or own, has attempted to acquire or own or may acquire or own common shares in the Company in violation of the above limit, the board of directors shall take such action as it deems advisable to refuse to give effect to, or to prevent such ownership or acquisition, including, but not limited to, the redemption of our common shares, refusal to give effect to the ownership or acquisition on our books or instituting proceedings to enjoin such ownership or acquisition.

The board of directors may waive the limit with respect to a particular shareholder if evidence satisfactory to the board of directors and our tax counsel is presented that such ownership will not then or in the future jeopardize our status as a REIT. As a condition of such waiver, the board of directors may require opinions of counsel satisfactory to it and/or an undertaking from the applicant with respect to preserving our REIT status. If our common shares are issued in excess of the ownership limit in our charter, or if our shares are transferred in a way that would cause our shares to be beneficially owned by fewer than 100 persons, then the issuance or transfer shall be void, and the intended transferee will acquire no rights to our shares.

The ownership limits described above will be automatically removed if our board of directors determines that it is no longer in our best interest to attempt to qualify, or to continue to qualify, as a REIT. Except as otherwise described above, any change in our ownership limits would require an amendment to our charter. Except for an amendment that would create dissenters’ rights, an amendment to our charter requiring shareholder approval will be adopted if the number of votes cast for it exceeds the number of votes cast against it at a shareholder meeting at which a quorum exists. In addition to preserving our status as a REIT, the ownership limit may have the effect of precluding an acquisition of control of the REIT without the approval of the board of directors.

All certificates representing our common shares will bear a legend referring to the restrictions described above.

All persons who own a specified percentage (or more) of our outstanding capital shares must annually file an affidavit with us containing information regarding their ownership of our capital shares, as set forth in the applicable Treasury Regulations promulgated under the Code. Under current Treasury Regulations, the percentage is set between 0.5% and 5%, depending on the number of record holders of our capital shares. In addition, each shareholder shall upon demand be required to disclose to us in writing the information with respect to the direct, indirect and constructive ownership of our capital shares as the board of directors deems necessary to comply with the provisions of the Code applicable to a REIT or to comply with the requirements of any taxing authority or governmental agency.

Anti-Takeover Considerations

In addition to the above, our charter and bylaws contain provisions that could delay, defer, or prevent a change in control of the Company or management. These provisions could also discourage a proxy contest and make it more difficult for shareholders to elect directors and take other corporate actions. As a result, these provisions could limit the price that investors are willing to pay in the future for our common shares. Such provisions include, but are not limited to, the following:

• Authorizing the board of directors to issue preferred shares;

• Prohibiting cumulative voting in the election of directors;

• Limiting the persons who may call special meetings of shareholders; and

• Establishing advance notice requirements for nominations for election to the board of directors for proposing matters that can be acted on by shareholders at shareholder meetings.

(1) Includes premiums and net of debt discount and unamortized debt origination costs. Excludes $2.0 million of unamortized debt origination costs related to unsecured lines of credit as of December 31, 2019 recorded in prepaids and other assets in the Consolidated Balance Sheet. Unamortized debt origination costs were $11.2 million and $14.1 million as of December 31, 2019 and 2018, respectively. Amortization of deferred debt origination costs included in interest expense for the years ended December 31, 2019, 2018 and 2017 was $3.0 million, $3.1 million and $3.3 million, respectively.

(2) The effective interest rate assigned during the purchase price allocation to this assumed mortgage during the acquisition in 2011 was 5.05%.

(3) Principal and interest due monthly with remaining principal due at maturity.

Certain of our properties, which had a net book value of approximately $174.2 million at December 31, 2019, serve as collateral for mortgages payable. We maintain unsecured lines of credit that, as of December 31, 2019, provided for borrowings of up to $600.0 million, including a separate $20.0 million liquidity line and a $580.0 million syndicated line. The syndicated line may be increased up to $1.2 billion through an accordion feature in certain circumstances. As of December 31, 2019, letters of credit totaling $170,000 were issued under the lines of credit.

The unsecured lines of credit and senior unsecured notes include covenants that require the maintenance of certain ratios, including debt service coverage and leverage, and limit the payment of dividends such that dividends and distributions will not exceed funds from operations, as defined in the agreements, for the prior fiscal year on an annual basis or 95% of funds from operations on a cumulative basis. As of December 31, 2019, we believe we were in compliance with all of our debt covenants.

2018 Transactions

Increased Borrowing Capacity and Extension of Unsecured Lines of Credit

In January 2018, we closed on amendments to our unsecured lines of credit, which increased the borrowing capacity from $520.0 million to $600.0 million and extended the maturity date from October 2019 to October 2021, with a one-year extension option. We also reduced the interest rate spread over LIBOR from 0.90% to 0.875%, and increased the incremental borrowing availability through an accordion feature on the syndicated line from $1.0 billion to $1.2 billion. Loan origination costs associated with the amendments totaled approximately $2.3 million.

Southaven Mortgage

In February 2018, the consolidated joint venture that owns the Tanger outlet center in Southaven, Mississippi amended and restated the $60.0 million mortgage loan secured by the property that was scheduled to mature in April 2018. The amended and restated loan reduced the principal balance to $51.4 million, increased the interest rate from LIBOR + 1.75% to LIBOR + 1.80% and extended the maturity to April 2021, with a two-year extension option. In March 2018, the consolidated joint venture entered into an interest rate swap, effective March 1, 2018, that fixed the base LIBOR rate at 2.47% on a notional amount of $40.0 million through January 31, 2021.

Unsecured Term Loan

In October 2018, we amended and restated our unsecured term loan, increasing the size of the loan from $325.0 million to $350.0 million, extending the maturity from April 2021 to April 2024, and reducing the interest rate spread over LIBOR from 0.95% to 0.90%. The $25.0 million of proceeds were used to pay down the balances outstanding under our unsecured lines of credit.

2017 Transactions

$300.0 Million Unsecured Senior Notes due 2027

In July 2017, we completed an underwritten public offering of $300.0 million of 3.875% senior notes due 2027 (the "2027 Notes"). The 2027 Notes priced at 99.579% of the principal amount to yield 3.926% to maturity. The 2027 Notes pay interest semi-annually at a rate of 3.875% per annum and mature on July 15, 2027. The net proceeds from the offering, after deducting the underwriting discount and offering expenses, were approximately $295.9 million. In August 2017, we used the net proceeds from the sale of the 2027 Notes, together with borrowings under our unsecured lines of credit, to redeem all of our 6.125% senior notes due 2020 (the "2020 Notes") (approximately $300.0 million in aggregate principal amount outstanding). The 2020 Notes were redeemed at par plus a “make-whole” premium of approximately $34.1 million. In addition, we wrote off approximately $1.5 million of unamortized debt discount and debt origination costs related to the 2020 Notes.

Foxwoods Debt Repayment

In November 2017, we repaid the $70.3 million floating rate mortgage loan secured by the Foxwoods property with borrowings under its unsecured floating rate lines of credit.

Debt Maturities

Maturities of the existing long-term debt as of December 31, 2019 for the next five years and thereafter are as follows (in thousands):

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2019

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.

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 control such properties. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities ("VIE"). For joint ventures that are determined to be a VIE, we consolidate the entity where we are deemed to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance, and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. Our determination of the primary beneficiary considers 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. As of December 31, 2019, we did not have a joint venture that was a VIE.

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.

The carrying amount of our investments in the Charlotte, Columbus, Galveston/Houston and National Harbor joint ventures are less than zero because of financing or operating distributions that were greater than net income, as net income includes non-cash charges for depreciation and amortization.

Noncontrolling interests

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 or losses are 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, 2019, 2018 and 2017 were as follows (in thousands):

	2019		2018		2017
Payroll and related costs capitalized	$	1,581	$	1,521	$	2,345
Interest costs capitalized	$	25	$	93	$	2,289

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, 2019, 2018 and 2017 was as follows (in thousands):

	2019		2018		2017
Depreciation expense related to rental property	$	107,129	$	114,198	$	107,845

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 are 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.

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.

Deferred Charges

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 internal leasing costs for the years ended December 31, 2019, 2018 and 2017 were as follows (in thousands):

	2019		2018		2017
Deferred lease costs capitalized- payroll and related costs	$	679	$	6,007	$	6,098
Total deferred lease costs capitalized	$	5,142	$	6,703	$	6,584

Due to the adoption of Accounting Standards Codification Topic 842 "Leases" ("ASC 842") on January 1, 2019, only direct internal leasing costs are capitalized and indirect internal leasing costs previously capitalized are now expensed. 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

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 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. The cash flow estimates used both for determining recoverability and estimating fair value are inherently judgmental and reflect current and projected trends in rental, occupancy, capitalization, and discount rates, and estimated holding periods for the applicable assets. The estimated fair value is based primarily on the income approach. The income approach involves discounting the estimated income stream and reversion (presumed sale) value of a property over an estimated holding period to a present value at a risk-adjusted rate. Discount rates and terminal capitalization rates utilized in this approach are derived from property-specific information, market transactions and other financial and industry data.

During the fourth quarter of 2019 and third quarter 2018, we recorded a $37.6 million and $49.7 million, respectively, impairment charge in our consolidated statement of operations which equaled the excess of the carrying value of our Jeffersonville outlet center over its estimated fair value. See Note 11 for additional information on the fair market value calculation. We recognized no impairment losses for our consolidated properties during the year ended December 31, 2017. See Note 6 for discussion of the impairment of our unconsolidated joint ventures at the Bromont, Quebec and Saint Sauveur, Quebec outlet centers during the years ended December 31, 2018 and 2017.

In addition, based upon current market conditions, one of our outlet centers has an estimated fair value significantly less than its recorded carrying value of approximately $100.0 million. However, based on our current plan with respect to that outlet center, we believe that its carrying amount is recoverable and therefore no impairment charge was recorded. Accordingly, we will continue to monitor circumstances and events in future periods that could affect inputs such as the expected holding period, operating cash flow forecasts and capitalization rates, utilized to determine whether an impairment charge is necessary.  As these inputs are difficult to predict and are subject to future events that may alter our assumptions, the future cash flows estimated by management in its impairment analysis may not be achieved, and actual losses or impairment may be realized in the future.

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.

Impairment of Investments

Impairment of Investments - On a periodic basis or if circumstances exist, 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 an other than temporary 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

Sales of Real Estate - For sales of real estate where we have consideration to which we are entitled in exchange for transferring the real estate, the related assets and liabilities are removed from the balance sheet and the resultant gain or loss is recorded in the period the transaction closes. Any post sale involvement is accounted for as a separate performance obligations and when the separate performance obligations are satisfied, the sales price allocated to each is recognized.

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 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.

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 2016 - 2019 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 it is not probable that 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 - As a lessor, substantially all of our revenues are earned from arrangements that are within the scope of ASC 842. We utilized the practical expedient in ASU 2018-11 to account for lease and non-lease components as a single component which resulted in all of our revenues associated with leases being recorded as rental revenues in the consolidated statements of operations. Base rentals are recognized on a straight-line basis over the term of the lease. Tenant expense reimbursements are recognized in the period the applicable expenses are incurred. As a result of combining all components of a lease, all fixed contractual payments, including consideration received from certain executory costs, are now recognized on a straight-line basis. Straight-line rent adjustments recorded as a receivable in other assets on the consolidated balance sheets were approximately $61.6 million and $57.5 million as of December 31, 2019 and 2018, respectively. Common area maintenance expense reimbursements are based on the tenant's proportionate share of the allocable operating expenses for the property. 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. The majority of our 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. 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. Expense reimbursements from unconsolidated joint ventures are recognized in the period the applicable expenses are incurred.

Uncollectible Tenant Revenues - Due to the adoption of ASC 842 effective January 1, 2019, uncollectible tenant revenues were recorded as a contra-revenue adjustment in 2019. If it is determined collection is not probable we record revenues on a cash basis. Previously in 2018 and 2017, these adjustments were recorded in general and administrative expense.

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 2019, 2018 or 2017.

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, Inc. 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 and we estimate expected forfeitures in determining compensation cost.

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

Recently adopted accounting standards (other than ASC 842 Leases, see Note 21)

In October 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2018-16, Inclusion of the Secured Overnight Financing Rate (“SOFR”) Overnight Index Swap (“OIS”) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes to Accounting Standards Codification 815. ASU 2018-16 expands the list of U.S. benchmark interest rates permitted in the application of hedge accounting by adding the OIS rate based on SOFR as an eligible benchmark interest rate. The mandatory effective date for calendar year-end public companies was January 1, 2019. The adoption of ASU 2018-16 as of January 1, 2019 did not have a material impact on our consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. ASU 2018-07 amends prior employee share-based payment guidance to include nonemployee share-based payment transactions for acquiring services or property. This ASU now aligns the determination of the measurement date, the accounting for performance conditions, and the accounting for share-based payments after vesting in addition to other items. The provisions of ASU 2018-07 were effective for us as of January 1, 2019 using a modified transition method upon adoption, and early adoption was permitted. The adoption of ASU 2018-07 as of January 1, 2019 did not have a material impact on our consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. The new guidance made more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amended the presentation and disclosure requirements and changed how companies assess effectiveness. It is intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The adoption of ASU 2017-12 as of January 1, 2019 did not have a material impact on our consolidated financial statements.

Recently issued accounting standards to be adopted

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 is intended to improve the effectiveness of disclosures required by entities regarding recurring and nonrecurring fair value measurements. ASU 2018-13 is effective for reporting periods beginning after December 15, 2019, with early adoption permitted. The adoption of ASU 2018-13 will not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13 to amend the accounting for credit losses for certain financial instruments. Under the new guidance, an entity recognizes its estimate of expected credit losses as an allowance, which the FASB believes will result in more timely recognition of such losses. In November 2018, the FASB released ASU No. 2018-19 “Codification Improvements to Topic 326, Financial Instruments - Credit Losses.” This ASU clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20 “Financial Instruments - Credit Losses.” Instead, impairment of receivables arising from operating leases should be accounted for under Subtopic 842-30 “Leases - Lessor.” ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The adoption of this new guidance will not have a material impact on our consolidated financial statements

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Commitments and Contingencies of Consolidated Properties

Capital expenditure commitments

Commitments to complete construction of our ongoing capital projects and other capital expenditure requirements amounted to approximately $17.7 million at December 31, 2019.

Litigation

We are also subject to legal proceedings and claims, which arise from time to time in the ordinary course of our business and have not been finally adjudicated. In our opinion, the ultimate resolution of these matters is not expected to have a material effect on our consolidated financial statements. We record a liability in our consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. We review these estimates each accounting period as additional information is known and adjust the loss provision when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, we estimate and disclose the possible loss or range of loss to the extent necessary to make the consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in our consolidated financial statements.

Employment Agreements

We are party to employment agreements with certain executives that provide for compensation and certain other benefits. The agreements also provide for severance payments under certain circumstances.

Commitments and Contingencies of Unconsolidated Properties

Capital expenditure commitments

Contractual commitments for ongoing capital projects and other capital expenditure requirements related to our unconsolidated joint ventures amounted to approximately $1.0 million at December 31, 2019, of which our portion was approximately $481,000. Contractual commitments represent only those costs subject to contracts which are legal binding agreements as of December 31, 2019 and do not necessary represent the total cost to complete the projects.

Debt

We provide guarantees to lenders for our joint ventures which include standard non-recourse carve out indemnifications for losses arising from items such as but not limited to fraud, physical waste, payment of taxes, environmental indemnities, misapplication of insurance proceeds or security deposits and failure to maintain required insurance. For construction and mortgage loans, we may include a guaranty of completion as well as a principal guaranty ranging from 5% to 100% of principal.  The principal guarantees include terms for release based upon satisfactory completion of construction and performance targets including occupancy thresholds and minimum debt service coverage tests. Our joint ventures may contain make whole provisions in the event that demands are made on any existing guarantees. As of December 31, 2019, the maximum amount of joint venture debt guaranteed by the Company is $19.4 million.

(1) The number of restricted common shares received under the 2019 and 2018 OPP will be determined on a pro-rata basis by linear interpolation between total shareholder return thresholds, both for absolute total shareholder return and for relative total shareholder return amongst the Company's peer group. The peer group is based on companies included in the FTSE NAREIT Retail Index.

(2) The performance shares for the 2017 OPP will convert on a pro-rata basis by linear interpolation between share price appreciation thresholds, both for absolute total shareholder return and for relative total shareholder return. The share price for the purposes of calculation of share price appreciation will be adjusted on a penny-for-penny basis with respect to any dividend payments made during the measurement period. The peer group is based on companies included in the SNL Equity REIT index.

(3) On February 15, 2019, the measurement period for the 2016 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 2016 OPP performance awards were automatically forfeited.

(4) On December 31, 2017, the measurement period for the 2015 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 2015 OPP performance awards were automatically forfeited.

Schedule of Share-based Payment Award, Stock Options, Valuation Assumptions

The fair values of the OPP awards granted during the years ended December 31, 2019, 2018, and 2017 were determined at the grant dates using a Monte Carlo simulation pricing model and the following assumptions:

	2019		2018		2017
Risk free interest rate (1)	2.55	%	2.40	%	1.52	%
Expected dividend yield (2)	5.3	%	4.8	%	3.4	%
Expected volatility (3)	24	%	27	%	19	%

(1) Represents the interest rate as of the grant date on U.S. 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.

Leasing Agreements

Leases [Abstract]

Leasing Agreements

Lease Agreements

On January 1, 2019, we adopted ASC 842, which supersedes ASC 840. We adopted ASC 842 using the modified retrospective approach, whereby there was no cumulative effect adjustments to retained earnings on adoption and prior periods were not restated. Accordingly, our leases and lease related costs, as both lessee and lessor, and lease related receivables, as lessor, are presented under ASC 842 for the year ended December 31, 2019 and under ASC 840 the year ended December 31, 2018.

As a lessor, substantially all of our revenues are earned from arrangements that are within the scope of ASC 842. We utilized the practical expedient in ASU 2018-11 to account for lease and non-lease components as a single component which resulted in all of our revenues associated with leases being recorded as rental revenues in the consolidated statements of operations. As a result of the adoption of ASC 842, the amounts disclosed in our Annual Report on Form 10-K for the year ended December 31, 2018 as base rentals, percentage rentals and expense reimbursements have now been combined into rental revenues on the consolidated statements of operations to conform to the current year presentation. In addition, certain amounts previously included in expense reimbursements in our Annual Report on Form10-K for the year ended December 31, 2018, which are not related to leases have been reclassified to management, leasing and other services and other revenues on the consolidated statements of operations to conform to the current year presentation. See Note 6 for additional details on the amounts reclassified to management, leasing and other services.

ASC 842 requires certain other accounting changes effective January 1, 2019 where prior year amounts are not reclassified or restated. Uncollectible tenant revenues previously recorded in general and administrative expense are recorded in rental revenues as a contra-revenue account in 2019. As a result of combining all components of a lease, all fixed contractual payments, including consideration received from certain executory costs, are now recognized on a straight-line basis. For the year ended December 31, 2019, we recorded a straight-line rent adjustment of $6.4 million in rental revenues in our consolidated statements of operations to record revenues from executory costs on a straight-line basis. In addition, direct internal leasing costs are capitalized, however, indirect internal leasing costs previously capitalized are now expensed. We only capitalize the portion of these types of costs incurred that are a direct result of an executed lease. For the year ended December 31, 2019, lease costs of approximately $4.9 million were expensed which would have been capitalized under ASC 840.

As a lessee, the new standard also provides a number of optional provisions, known as practical expedients, which companies may elect to adopt to facilitate implementation. We elected the package of practical expedients which, among other items, precludes us from needing to reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification of any expired or existing leases, and (3) initial direct costs for any existing leases.

Information as Lessor Under ASC 842

As of December 31, 2019, we were the lessor to over 2,400 stores in our 32 consolidated outlet centers, under operating leases with initial terms that expire from 2020 to 2035, with certain agreements containing extension options. We also have certain agreements which require tenants to pay their portion of reimbursable expenses such as common area expenses, utilities, insurance and real estate taxes.

For the year ended December 31, 2019, the components of rental revenues are as follows (in thousands):

	2019
Rental revenues - fixed	$	360,513
Rental revenues - variable (1)	103,433
Rental revenues	$	463,946

(1) Primarily includes rents based on a percentage of tenant sales volume and reimbursable expenses such as common area expenses, utilities, insurance and real estate taxes.

Future minimum lease receipts under non-cancelable operating leases as of December 31, 2019, excluding the effect of straight-line rent and variable rentals, are as follows (in thousands):

2020	$	316,397

Information as Lessor Under ASC 840

As of December 31, 2018, we were the lessor to over 2,600 stores in our 36 consolidated outlet centers, under operating leases with initial terms that expire from 2019 to 2033. The majority of our leases contain provisions which provide additional rents based on tenants’ sales volume. Percentage rentals are recognized when specified targets that trigger the contingent rent are met.

Future minimum lease receipts under non-cancelable operating leases as of December 31, 2018, excluding the effect of straight-line rent and variable rentals, are as follows (in thousands):

Information as Lessee Under ASC 842

Adoption of the new standard resulted in the recording of operating lease right-of-use assets and operating lease liabilities, of $90.4 million and $95.1 million, respectively, as of January 1, 2019 equal to the present value of the minimum lease payments required under each lease. The difference between the recorded operating lease liability and operating right-of-use assets represents the accrued straight-line rent liability and our prepaid rent balances previously recognized under ASC 840.  In March 2019, we sold our Ocean City outlet center, which had an operating lease right-of-use asset and operating lease liability of approximately $2.5 million.

Our non-cancelable operating leases, with terms in excess of one year, have terms, including certain extension options, that expire from 2028 to 2101. Certain extension options, which are reasonably certain at inception, are used in the calculation of our operating lease right-of-use assets based on the economic life of the asset. Leases with an initial term of 12 months or less (short-term leases) are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. The majority of our operating lease expense is related to ground leases at the following outlet centers: Myrtle Beach Hwy 17, Atlantic City, Sevierville, Riverhead, Foxwoods and Rehoboth Beach and the lease of our corporate office in Greensboro, North Carolina.

For the year ended December 31, 2019, the components of lease costs are as follows (in thousands):

	2019
Operating lease costs	$	5,519
Short-term lease costs	2,297
Variable lease costs (1)	231
Total lease costs	$	8,047

(1) Our variable lease costs relate to our ground leases where increases in payments are based on center financial performance.

The discount rate applied to measure each operating lease right-of-use asset and operating lease liability is based on our incremental borrowing rate (“IBR”). We consider the general economic environment and our credit rating and factor in various financing and asset specific adjustments to ensure the IBR is appropriate based on the intended use of the underlying lease. The lease term and discount rates are as follows:

	2019
Weighted - average remaining lease term (years)	50
Weighted - average discount rate	5.0	%

Cash flow information related to leases for the year ended December 31, 2019 was as follows (in thousands):

Total lease payments	$	255,200
Less imputed interest	163,963
Present value of lease liabilities	$	91,237

Information as Lessee Under ASC 840

As of December 31, 2018, our non-cancelable operating leases have terms, including certain extension options, that expire from 2019 to 2101. Rental payments for these leases totaled approximately $7.2 million and $7.1 million, for the years ended December 31, 2018 and 2017, respectively. As of December 31, 2018, the majority of our rental payments are related to ground leases at the following outlet centers: Myrtle Beach Hwy 17, Atlantic City, Ocean City, Sevierville, Riverhead, Foxwoods and Rehoboth Beach and the lease of our corporate office in Greensboro, North Carolina. The contingent portion of our ground lease payments is based on center performance and/or changes in an index.

Partners' Equity of the Operating Partnership

Partners' Equity of the Operating Partnership

All units of partnership interest issued by the Operating Partnership have equal rights with respect to earnings, dividends and net assets. When the Company issues common shares upon the exercise of options, the issuance of restricted share awards or the exchange of Class A common limited partnership units, the Operating Partnership issues a corresponding Class B common limited partnership unit to Tanger LP Trust, a wholly-owned subsidiary of the Company. Likewise, when the Company repurchases its outstanding common shares, the Operating Partnership repurchases corresponding Class B common limited partnership units held by Tanger LP Trust.

The following table sets forth the changes in outstanding partnership units for the years ended December 31, 2019, 2018 and 2017:

Equity-Based Compensation

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.

As of December 31, 2019, we may issue up to 18.7 million common shares under the Plan. Shares remaining available for future issuance totaled approximately 3,854,000 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, 2019, 2018 and 2017, respectively, as follows (in thousands):

	2019		2018		2017
Restricted common shares	$	12,036	$	9,870	$	9,395
Notional unit performance awards	5,918		4,356		3,913
Options	166		443		277
Total equity-based compensation	$	18,120	$	14,669	$	13,585

Equity-based compensation expense capitalized as a part of rental property and deferred lease costs were as follows (in thousands):

	2019		2018		2017
Equity-based compensation expense capitalized	$	384	$	1,131	$	1,044

As of December 31, 2019, there was $15.3 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 2.4 years.

Restricted Common Share and Restricted Share Unit Awards

During 2019, 2018 and 2017, the Company granted approximately 309,000, 407,000 and 253,000 restricted common shares and restricted share units, respectively, to the Company's non-employee directors and the Company's senior executive officers. The non-employee directors' restricted common shares generally vest ratably over a three year period and the senior executive officers' restricted common shares (other than our Chief Executive Officer's) generally vest ratably over periods ranging from three to five years. For the restricted common shares and restricted share units issued to our chief executive officer during 2019, 2018 and 2017, the award agreements generally require him to hold the shares or units issued to him for a minimum of three years following each applicable vesting date or the share issuance date, as applicable. Compensation expense related to the amortization of the deferred compensation is being recognized in accordance with the vesting schedule of the restricted common shares and restricted share units. For all of the restricted common share and restricted share unit awards described above, the grant date fair value of the awards were determined based upon the closing market price of the Company's common shares on the day prior to the grant date.

The following table summarizes information related to unvested restricted common shares and restricted share units outstanding for the years ended December 31, 2019, 2018, and 2017:

(2) Includes 51,217 restricted share units.

The table above excludes restricted common shares earned under the 2014 Outperformance Plan. In connection with the 2014 Outperformance Plan, we issued approximately 184,000 restricted common shares in January 2017, with approximately 94,000 vesting immediately and the remaining 90,000 vesting in January 2018, contingent upon continued employment with the Company through the vesting date (unless terminated prior thereto (a) by the Company without cause, (b) by participant for good reason or (c) due to death or disability).

The total value of restricted common shares vested during the years ended 2019, 2018 and 2017 was $9.2 million, $9.2 million and $12.4 million, respectively. During 2019, 2018 and 2017, we withheld shares with value equivalent to the employees' 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 approximately 132,000, 89,000 and 70,000 for 2019, 2018 and 2017, 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 $2.5 million, $2.1 million and $2.4 million for 2019, 2018 and 2017, respectively, which are reflected as a financing activity within the consolidated statements of cash flows.

Notional Unit Performance Awards

Outperformance Plan

Each year, the Compensation Committee of Tanger Factory Outlet Centers, Inc. approves the terms and the number of awards to be granted under the Tanger Factory Outlet Centers, Inc. Outperformance Plan (the “OPP"). The OPP is a long-term 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 absolute total shareholder return) and its share price appreciation relative to its peer group (or relative total shareholder return) over a three-year measurement period. For all recipients (other than our chief executive officer), any shares earned at the end of the three-year measurement period are subject to a time-based vesting schedule, with 50% of the shares vesting immediately following the measurement period, and the remaining 50% vesting one year thereafter, contingent upon continued employment with the Company through the vesting date (unless terminated prior thereto (a) by the Company without cause, (b) by participant for good reason or (c) due to death or disability. For our chief executive officer, any shares earned at the end of the three-year measurement period remain subject to a time-based vesting schedule and are issued following vesting, with 50% of the shares vesting immediately following issuance, 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 due to retirement or (c) due to death or disability).

The following table sets forth OPP performance targets and other relevant information about each plan:

(1) The number of restricted common shares received under the 2019 and 2018 OPP will be determined on a pro-rata basis by linear interpolation between total shareholder return thresholds, both for absolute total shareholder return and for relative total shareholder return amongst the Company's peer group. The peer group is based on companies included in the FTSE NAREIT Retail Index.

(2) The performance shares for the 2017 OPP will convert on a pro-rata basis by linear interpolation between share price appreciation thresholds, both for absolute total shareholder return and for relative total shareholder return. The share price for the purposes of calculation of share price appreciation will be adjusted on a penny-for-penny basis with respect to any dividend payments made during the measurement period. The peer group is based on companies included in the SNL Equity REIT index.

(3) On February 15, 2019, the measurement period for the 2016 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 2016 OPP performance awards were automatically forfeited.

(4) On December 31, 2017, the measurement period for the 2015 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 2015 OPP performance awards were automatically forfeited.

The fair values of the OPP awards granted during the years ended December 31, 2019, 2018, and 2017 were determined at the grant dates using a Monte Carlo simulation pricing model and the following assumptions:

	2019		2018		2017
Risk free interest rate (1)	2.55	%	2.40	%	1.52	%
Expected dividend yield (2)	5.3	%	4.8	%	3.4	%
Expected volatility (3)	24	%	27	%	19	%

(1) Represents the interest rate as of the grant date on U.S. 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, 2019, 2018, and 2017:

Exercisable as of December 31, 2019	284,500		$	28.61	4.27	$	—

During February 2018, the Company granted 331,000 options to non-executive employees of the Company. The exercise price of the options granted during the first quarter of 2018 was $21.94 per share 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, which resulted in a weighted average grant date fair value per share of $3.62 and included the following weighted-average assumptions: expected dividend yield 6.24%; expected life of 7.1 years; expected volatility of 32.47%; a risk-free rate of 2.8%; and forfeiture rates of 3.0% to 10.0% dependent upon the employee's position within the Company. The total intrinsic value of options exercised during the year ended December 31, 2017 was $8,000. For both the years ended December 31, 2019 and 2018, no options were exercised.

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, 2019, 2018 and 2017, we contributed approximately $889,000, $872,000 and $862,000, respectively, to the 401(k) Retirement Savings Plan.

Share Repurchase Program

In May 2017, the Company announced that our Board of Directors authorized the repurchase of up to $125.0 million of its outstanding common shares as market conditions warrant over a period commencing on May 19, 2017 and expiring on May 18, 2019.  In February 2019, the Company’s Board of Directors authorized the repurchase of an additional $44.3 million of our outstanding common shares for an aggregate authorization of $169.3 million until May 2021. Repurchases may be made from time to time through open market, privately-negotiated, structured or derivative transactions (including accelerated share repurchase transactions), or other methods of acquiring shares. The Company intends to structure open market purchases to occur within pricing and volume requirements of Rule 10b-18.  The Company may, from time to time, enter into Rule 10b5-1 plans to facilitate the repurchase of its shares under this authorization.

Shares repurchased during the years ended December 31, 2019, 2018 and 2017 were as follows:

	Year Ended December 31,
	2019		2018		2017

Earnings Per Unit of the Operating Partnership

The following table sets forth a reconciliation of the numerators and denominators in computing earnings per unit for the years ended December 31, 2019, 2018 and 2017 (in thousands, except per unit amounts):

	2019			2018			2017
Numerator
Net income attributable to partners of the Operating Partnership	$	92,533		$	45,984		$	71,611
Allocation of earnings to participating securities	(1,336		)	(1,211		)	(1,209		)
Net income available to common unitholders of the Operating Partnership	$	91,197		$	44,773		$	70,402
Denominator
Basic weighted average common units	97,766			98,302			99,533
Effect of outstanding options and certain restricted common units	—			1			16
Diluted weighted average common units	97,766			98,303			99,549
Basic earnings per common unit:
Net income	$	0.93		$	0.45		$	0.71
Diluted earnings per common unit:
Net income	$	0.93		$	0.45		$	0.71

We determine diluted earnings per unit based on the weighted average number of common units outstanding combined with the incremental weighted average units that would have been outstanding assuming all potentially dilutive securities were converted into common units at the earliest date possible. There were no material securities which had a dilutive effect on earnings per common share for the years ended December 31, 2019 and 2018.

Notional units granted under our equity compensation plan are considered contingently issuable common units and are included in earnings per unit if the effect is dilutive using the treasury stock method and the common units would be issuable if the end of the reporting period were the end of the contingency period. For the years ended December 31, 2019, 2018, and 2017, approximately 1.1 million, 1.0 million and 603,000 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 or because they were anti-dilutive. The notional units are considered contingently issuable common units and are included in earnings per unit if the effect is dilutive using the treasury stock method.

With respect to outstanding options, the effect of dilutive common units 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 units at the average market price during the period. The market price of a common unit is considered to be equivalent to the market price of a Company common share. For the years ended December 31, 2019, 2018 and 2017, approximately 523,000, 535,000 and 169,000 options were excluded from the computation, respectively.

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.

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 Tanger Properties Limited Partnership and subsidiaries, which we refer to as the Operating Partnership, focuses exclusively on developing, acquiring, owning, operating and managing outlet shopping centers. As of December 31, 2019, we owned and operated 32 consolidated outlet centers, with a total gross leasable area of approximately 12.0 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 97% occupied and contained over 2,400 stores, representing approximately 400 store brands. We also had partial ownership interests in 7 unconsolidated outlet centers totaling approximately 2.2 million square feet, including 3 outlet centers in Canada.

Our outlet centers and other assets are held by, and all of our operations are conducted by 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, 2019, the Company, through its ownership of Tanger GP Trust and Tanger LP Trust, owned 92,892,260 units of the Operating Partnership and other limited partners (the "Non-Company LPs") collectively owned 4,911,173 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.

Noncontrolling Interests

Dec. 31, 2019

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 2019 and 2018, 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, 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, and units repurchased by the Operating Partnership as a result of the Company's repurchase of its outstanding common shares. As discussed in Note 13, for the years ended December 31, 2019 and 2018, Non-Company LPs exchanged 49,511 and 34,749 Class A common limited partnership units of the Operating Partnership, respectively, for an equal number of common shares of the Company. In addition, for the years ended December 31, 2019 and 2018, the Company repurchased approximately 1,209,328 and 919,249 common shares, respectively, on the open market and the Operating Partnership repurchased an equal number of units held by the Company.

The changes in the Company's ownership interests in the subsidiaries impacted consolidated equity during the periods shown as follows (in thousands):

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 and intend to provide further financial support to these joint ventures. 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 and equity in earnings of the joint ventures.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Reclassifications- Certain prior period balances in the accompanying consolidated statements of operations have been reclassified or combined to conform to the current period presentation. See Note 6 and Note 21 for additional details on the amounts reclassified.

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 control such properties. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities ("VIE"). For joint ventures that are determined to be a VIE, we consolidate the entity where we are deemed to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance, and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. Our determination of the primary beneficiary considers 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. As of December 31, 2019, we did not have a joint venture that was a VIE.

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.

The carrying amount of our investments in the Charlotte, Columbus, Galveston/Houston and National Harbor joint ventures are less than zero because of financing or operating distributions that were greater than net income, as net income includes non-cash charges for depreciation and amortization.

Noncontrolling interests - In the 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 or losses are 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, 2019, 2018 and 2017 were as follows (in thousands):

	2019		2018		2017
Payroll and related costs capitalized	$	1,581	$	1,521	$	2,345
Interest costs capitalized	$	25	$	93	$	2,289

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, 2019, 2018 and 2017 was as follows (in thousands):

	2019		2018		2017
Depreciation expense related to rental property	$	107,129	$	114,198	$	107,845

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 are 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.

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.

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 internal leasing costs for the years ended December 31, 2019, 2018 and 2017 were as follows (in thousands):

	2019		2018		2017
Deferred lease costs capitalized- payroll and related costs	$	679	$	6,007	$	6,098
Total deferred lease costs capitalized	$	5,142	$	6,703	$	6,584

Due to the adoption of Accounting Standards Codification Topic 842 "Leases" ("ASC 842") on January 1, 2019, only direct internal leasing costs are capitalized and indirect internal leasing costs previously capitalized are now expensed. 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. The cash flow estimates used both for determining recoverability and estimating fair value are inherently judgmental and reflect current and projected trends in rental, occupancy, capitalization, and discount rates, and estimated holding periods for the applicable assets. The estimated fair value is based primarily on the income approach. The income approach involves discounting the estimated income stream and reversion (presumed sale) value of a property over an estimated holding period to a present value at a risk-adjusted rate. Discount rates and terminal capitalization rates utilized in this approach are derived from property-specific information, market transactions and other financial and industry data.

During the fourth quarter of 2019 and third quarter 2018, we recorded a $37.6 million and $49.7 million, respectively, impairment charge in our consolidated statement of operations which equaled the excess of the carrying value of our Jeffersonville outlet center over its estimated fair value. See Note 11 for additional information on the fair market value calculation. We recognized no impairment losses for our consolidated properties during the year ended December 31, 2017. See Note 6 for discussion of the impairment of our unconsolidated joint ventures at the Bromont, Quebec and Saint Sauveur, Quebec outlet centers during the years ended December 31, 2018 and 2017.

In addition, based upon current market conditions, one of our outlet centers has an estimated fair value significantly less than its recorded carrying value of approximately $100.0 million. However, based on our current plan with respect to that outlet center, we believe that its carrying amount is recoverable and therefore no impairment charge was recorded. Accordingly, we will continue to monitor circumstances and events in future periods that could affect inputs such as the expected holding period, operating cash flow forecasts and capitalization rates, utilized to determine whether an impairment charge is necessary.  As these inputs are difficult to predict and are subject to future events that may alter our assumptions, the future cash flows estimated by management in its impairment analysis may not be achieved, and actual losses or impairment may be realized in the future.

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 or if circumstances exist, 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 an other than temporary 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 of real estate where we have consideration to which we are entitled in exchange for transferring the real estate, the related assets and liabilities are removed from the balance sheet and the resultant gain or loss is recorded in the period the transaction closes. Any post sale involvement is accounted for as a separate performance obligations and when the separate performance obligations are satisfied, the sales price allocated to each is recognized.

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 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.

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 2016 - 2019 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 it is not probable that 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, 2019, 2018 and 2017 were taxable as follows:

Common dividends per share:	2019		2018		2017
Ordinary income	$	1.3261	$	1.3919	$	1.1660
Capital gain	—		0.0006		—
Return of capital	0.0889		—		0.1865
	$	1.4150	$	1.3925	$	1.3525

The following reconciles net income available to the Company's shareholders to taxable income available to common shareholders for the years ended December 31, 2019, 2018 and 2017 (in thousands):

	2019			2018			2017
Net income available to the Company's shareholders	$	87,855		$	43,655		$	68,002

Other differences	8,948			(630		)	(1,089		)
Taxable income available to common shareholders	$	116,960		$	122,703		$	84,763

Revenue Recognition - As a lessor, substantially all of our revenues are earned from arrangements that are within the scope of ASC 842. We utilized the practical expedient in ASU 2018-11 to account for lease and non-lease components as a single component which resulted in all of our revenues associated with leases being recorded as rental revenues in the consolidated statements of operations. Base rentals are recognized on a straight-line basis over the term of the lease. Tenant expense reimbursements are recognized in the period the applicable expenses are incurred. As a result of combining all components of a lease, all fixed contractual payments, including consideration received from certain executory costs, are now recognized on a straight-line basis. Straight-line rent adjustments recorded as a receivable in other assets on the consolidated balance sheets were approximately $61.6 million and $57.5 million as of December 31, 2019 and 2018, respectively. Common area maintenance expense reimbursements are based on the tenant's proportionate share of the allocable operating expenses for the property. 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. The majority of our 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. 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. Expense reimbursements from unconsolidated joint ventures are recognized in the period the applicable expenses are incurred.

Uncollectible Tenant Revenues - Due to the adoption of ASC 842 effective January 1, 2019, uncollectible tenant revenues were recorded as a contra-revenue adjustment in 2019. If it is determined collection is not probable we record revenues on a cash basis. Previously in 2018 and 2017, these adjustments were recorded in general and administrative expense.

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 2019, 2018 or 2017.

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, 2019, 2018 and 2017 (in thousands):

	2019		2018		2017
Costs relating to construction included in accounts payable and accrued expenses	$	17,619	$	15,772	$	32,060

Interest paid, net of interest capitalized was as follows for the years ended December 31, 2019, 2018 and 2017 (in thousands):

	2019		2018		2017
Interest paid, net of interest capitalized	$	57,237	$	60,529	$	56,730

Information related to non-cash assets and liabilities recorded as a result of the adoption of ASC 842 in 2019 was as follows (in thousands):

	2019
Non-Cash operating lease right-of-use assets exchanged for operating lease liabilities	$	87,679
Non-Cash operating lease liabilities exchanged for operating right-of-use assets	$	92,354

The difference between the recorded operating lease liabilities and operating right-of-use assets represents the accrued straight-line rent liability of $5.0 million and our prepaid rent balances of $307,000 previously recognized under Accounting Standards Codification Topic 840 “Leases” (“ASC 840”) that were reclassified to the operating leases right-of use assets under ASC 842. 

Accounting for Equity-Based Compensation - We have a shareholder approved equity-based compensation plan, the Incentive Award Plan of Tanger Factory Outlet Centers, Inc. 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 and we estimate expected forfeitures in determining compensation cost.

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.

Recently adopted accounting standards (other than ASC 842 Leases, see Note 21)

In October 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2018-16, Inclusion of the Secured Overnight Financing Rate (“SOFR”) Overnight Index Swap (“OIS”) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes to Accounting Standards Codification 815. ASU 2018-16 expands the list of U.S. benchmark interest rates permitted in the application of hedge accounting by adding the OIS rate based on SOFR as an eligible benchmark interest rate. The mandatory effective date for calendar year-end public companies was January 1, 2019. The adoption of ASU 2018-16 as of January 1, 2019 did not have a material impact on our consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. ASU 2018-07 amends prior employee share-based payment guidance to include nonemployee share-based payment transactions for acquiring services or property. This ASU now aligns the determination of the measurement date, the accounting for performance conditions, and the accounting for share-based payments after vesting in addition to other items. The provisions of ASU 2018-07 were effective for us as of January 1, 2019 using a modified transition method upon adoption, and early adoption was permitted. The adoption of ASU 2018-07 as of January 1, 2019 did not have a material impact on our consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. The new guidance made more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amended the presentation and disclosure requirements and changed how companies assess effectiveness. It is intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The adoption of ASU 2017-12 as of January 1, 2019 did not have a material impact on our consolidated financial statements.

Recently issued accounting standards to be adopted

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 is intended to improve the effectiveness of disclosures required by entities regarding recurring and nonrecurring fair value measurements. ASU 2018-13 is effective for reporting periods beginning after December 15, 2019, with early adoption permitted. The adoption of ASU 2018-13 will not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13 to amend the accounting for credit losses for certain financial instruments. Under the new guidance, an entity recognizes its estimate of expected credit losses as an allowance, which the FASB believes will result in more timely recognition of such losses. In November 2018, the FASB released ASU No. 2018-19 “Codification Improvements to Topic 326, Financial Instruments - Credit Losses.” This ASU clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20 “Financial Instruments - Credit Losses.” Instead, impairment of receivables arising from operating leases should be accounted for under Subtopic 842-30 “Leases - Lessor.” ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The adoption of this new guidance will not have a material impact on our consolidated financial statements.

(1) Net of debt origination costs and including premiums of $1.1 million and $1.4 million as of December 31, 2019 and 2018, respectively.

(2) 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 and intend to provide further financial support to these joint ventures. 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 and equity in earnings of the joint ventures.

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,
	2019		2018		2017
Fees:
Management and marketing	$	2,308	$	2,334	$	2,310

Expense reimbursements from unconsolidated joint ventures	2,985		2,499		1,212
Total Fees	$	5,419	$	4,995	$	3,664

Expense reimbursements from unconsolidated joint ventures were previously included in expense reimbursements in our Form 10-K for the year ended December 31, 2018. As these revenues are not related to leases, the 2018 amounts have been reclassified to management, leasing and other services on the consolidated statements of operations to conform to the current year presentation. See Note 21 for discussion of adoption of ASC 842.

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 $3.8 million and $4.1 million as of December 31, 2019 and 2018, 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. In June 2018, the Charlotte joint venture closed on a $100.0 million mortgage loan with a fixed interest rate of approximately 4.3% and a maturity date of July 2028. The proceeds from the loan were used to pay off the existing $90.0 million mortgage loan with an interest rate of LIBOR + 1.45%, which had an original maturity date of November 2018. The joint venture distributed the incremental net loan proceeds of $9.3 million equally to the partners. Our partner is providing property management, marketing and leasing services to the joint venture.

Columbus

In June 2016, we opened an approximately 355,000 square foot outlet center in Columbus, Ohio. The development was initially fully funded with equity contributed to the joint venture by Tanger and its partner. 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 matured 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. In October 2019, the joint venture exercised its first option to extend the mortgage loan for one year to November 2020 under the same terms. We are providing property management, marketing and leasing services to the joint venture.

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. In July 2017, the joint venture amended and restated the initial construction loan, which had an outstanding balance of $65.0 million, to increase the amount available to borrow from $70.0 million to $80.0 million and extended the maturity date until July 2020 with two one-year options. The amended and restated loan also changed the interest rate from LIBOR + 1.50% to LIBOR + 1.65%. At the closing of the amendment, the joint venture distributed the net proceeds of approximately $14.5 million equally between the partners. 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 December 2018, the National Harbor joint venture closed on a $95.0 million mortgage loan with a fixed interest rate of approximately 4.6% and a maturity date of January 2030. The proceeds from the loan were used to pay off the $87.0 million construction loan with an interest rate of LIBOR + 1.65%, which had an original maturity date of November 2019. The joint venture distributed the incremental net loan proceeds of $7.4 million equally to the partners.

RioCan Canada

We have a 50/50 co-ownership agreement with RioCan Real Estate Investment Trust to operate and manage outlet centers in Canada. We provide leasing and marketing services for the outlet centers and RioCan provides 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 2016, the co-owners commenced construction on a 39,000 square foot expansion, which opened during the second quarter of 2017 to bring the total square feet of the outlet center to approximately 357,000.

Other properties owned by the RioCan Canada co-owners include Cookstown Outlet Mall and Les Factoreries Saint-Sauveur. Cookstown Outlet Mall is approximately 308,000 square feet and Les Factoreries Saint-Sauveur is approximately 116,000 square feet.

In May 2019, the RioCan joint venture closed on the sale of its 161,000 square foot outlet center in Bromont, for net proceeds of approximately $6.4 million. Our share of the proceeds was approximately $3.2 million. As a result of this transaction, we recorded a foreign currency loss of approximately $3.6 million in other income (expense), which had been previously recorded in other comprehensive income.

During 2018 and 2017, the Rio-Can joint venture recognized impairment charges related to its Bromont and Saint Sauveur properties. The impairment charges were primarily driven by, among other things, new competition in the market and changes in market capitalization rates.

The table below summarizes the impairment charges taken during 2018 and 2017 (in thousands):

		Impairment Charge(1)
	Outlet Center	Total		Our Share
2018	Bromont and Saint Sauveur	$	14,359	$	7,180
2017	Bromont and Saint Sauveur	$	18,042	$	9,021

(1) The fair value was determined using an income approach considering the prevailing market income capitalization rates for similar assets.

2017 Acquisition

Foxwoods

In November 2017, we successfully settled litigation with the estate of our former partner in the Foxwoods, Connecticut joint venture.  In return for mutual releases and no cash consideration, the estate tendered its partnership interest to the Company. Prior to this settlement, we had a 100% economic interest in the consolidated joint venture as a result of our preferred equity interest and the capital and distribution provisions in the joint venture agreement.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair value guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers are defined as follows:

Tier	Description
Level 1	Observable inputs such as quoted prices in active markets
Level 2	Inputs other than quoted prices in active markets that are either directly or indirectly observable
Level 3	Unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions

Fair Value Measurements on a Recurring Basis

The following table sets forth our assets and liabilities that are measured at fair value within the fair value hierarchy (in thousands):

			Level 1		Level 2		Level 3
			Quoted Prices in Active Markets for Identical Assets or Liabilities		Significant Observable Inputs		Significant Unobservable Inputs
	Total
Fair value as of December 31, 2019:
Asset:
Interest rate swaps (prepaids and other assets)	$	1,018	$	—	$	1,018	$	—
Total assets	$	1,018	$	—	$	1,018	$	—
Liabilities:
Interest rate swaps (other liabilities)	$	1,442	$	—	$	1,442	$	—
Total liabilities	$	1,442	$	—	$	1,442	$	—

			Level 1		Level 2		Level 3
			Quoted Prices in Active Markets for Identical Assets or Liabilities		Significant Observable Inputs		Significant Unobservable Inputs
	Total
Fair value as of December 31, 2018:
Assets:
Interest rate swaps (prepaids and other assets)	$	5,755	$	—	$	5,755	$	—
Total assets	$	5,755	$	—	$	5,755	$	—
Liabilities:
Interest rate swaps (other liabilities)	$	6	$	—	$	6	$	—
Total liabilities	$	6	$	—	$	6	$	—

Fair values of interest rate swaps are approximated using Level 2 inputs based on current market data received from financial sources that trade such instruments and are based on prevailing market data and derived from third party proprietary models based on well recognized financial principles including counterparty risks, credit spreads and interest rate projections, as well as reasonable estimates about relevant future market conditions.

Fair Value Measurements on a Nonrecurring Basis

The following table sets forth our assets that are measured at fair value on a nonrecurring basis 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, 2019:
Asset:
Long-lived assets	$	10,000	$	—	$	—	$	10,000
Fair value as of September 30, 2018:
Asset:
Long-lived assets	$	50,000	$	—	$	—	$	50,000

During the third quarter 2018, we determined that the estimated future undiscounted cash flows of our Jeffersonville outlet center did not exceed the property's carrying value. This shortfall was due to an expected decline in operating results caused by anticipated store closures from bankruptcy filings and brand-wide restructurings and a shift in the local competitive environment. Accordingly we recorded a $49.7 million impairment charge in our consolidated statement of operations which equaled the excess of the carrying value of our Jeffersonville outlet center over its estimated fair value. The estimated fair value was based on the income approach. The income approach involves discounting the estimated income stream and reversion (presumed sale) value of a property over an estimated holding period to a present value at a risk-adjusted rate.

During the fourth quarter of 2019, in anticipation of further store closings and declining operating results, we recorded an additional impairment charge of $37.6 million in our consolidated statement of operations which equaled the excess of the carrying value of our Jeffersonville outlet center over its estimated fair value. The estimated fair value was based on the income approach.

Discount rates and terminal capitalization rates utilized in the approach above were derived from property-specific information, market transactions and other financial and industry data. The terminal capitalization rate and discount rate are significant unobservable inputs in determining the fair value. These inputs are classified under Level 3 in the fair value hierarchy above.

The table below summarizes the terminal capitalization rate and discount rate used:

	December 31, 2019		September 30, 2018
Terminal capitalization rate	12	%	10	%
Discount rate	13	%	10	%

Other Fair Value Disclosures

The estimated fair value and recorded value of our debt as of December 31, 2019 and 2018 were as follows (in thousands):

	2019		2018
Level 1 Quoted Prices in Active Markets for Identical Assets or Liabilities	$	—	$	—
Level 2 Significant Observable Inputs	1,169,481		1,085,138
Level 3 Significant Unobservable Inputs	434,333		583,337
Total fair value of debt	$	1,603,814	$	1,668,475
Recorded value of debt	$	1,569,773	$	1,712,918

Our senior unsecured notes are publicly-traded which provides quoted market rates. However, due to the limited trading volume of these notes, we have classified these instruments as Level 2 in the hierarchy. Our other debt is classified as Level 3 given the unobservable inputs utilized in the valuation. Our unsecured term loan, unsecured lines of credit and variable interest rate mortgages are all LIBOR based instruments. When selecting the discount rates for purposes of estimating the fair value of these instruments, we evaluated the original credit spreads and do not believe that the use of them differs materially from current credit spreads for similar instruments and therefore the recorded values of these debt instruments is considered their fair value.

The carrying values of cash and cash equivalents, receivables, accounts payable, accrued expenses and other assets and liabilities are reasonable estimates of their fair values because of the short maturities of these instruments.

Earnings Per Share of the Company

Net income	$	0.93		$	0.45		$	0.71
Diluted earnings per common share:
Net income	$	0.93		$	0.45		$	0.71

We determine diluted earnings per share based on the weighted average number of common shares outstanding combined with the incremental weighted average shares that would have been outstanding assuming all potentially dilutive securities were converted into common shares at the earliest date possible. There were no material securities which had a dilutive effect on earnings per common share for the years ended December 31, 2019 and 2018.

Notional units granted under our equity compensation plan are considered contingently issuable common shares and are included in earnings per share if the effect is dilutive using the treasury stock method and the common shares would be issuable if the end of the reporting period were the end of the contingency period. For the years ended December 31, 2019, 2018, and 2017, approximately 1.1 million, 1.0 million and 603,000 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 or because they were anti-dilutive.

With respect to outstanding options, the effect of dilutive common shares is determined using the treasury stock method whereby outstanding options are assumed exercised at the beginning of the reporting period and the exercise proceeds from such options and the average measured but unrecognized compensation cost during the period are assumed to be used to repurchase our common shares at the average market price during the period. For the years ended December 31, 2019, 2018 and 2017, approximately 523,000, 535,000 and 169,000 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.
