PART I

ITEM 1. Business

General Development of Business .    Weingarten Realty Investors is a real estate investment trust (“REIT”) organized under the Texas Business Organizations Code. We, and our predecessor entity, began the ownership of shopping centers and other commercial real estate in 1948. Our primary business is leasing space to tenants in the shopping centers we own or lease. We also provide property management services for which we charge fees to either joint ventures where we are partners or other outside owners.

See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Item 7 and the Consolidated Financial Statements and Notes thereto included in Item 8 of this Annual Report on Form 10-K for the year ended December 31, 2017 , for information on certain recent developments of the Company.

Financial Information about Segments.     We are in the business of owning, managing and developing retail shopping centers. As each of our centers has similar characteristics and amenities, our operations have been aggregated into one reportable segment. See the Consolidated Financial Statements and Notes thereto included in Item 8 of this Annual Report on Form 10-K for further information regarding reportable segments.

Narrative Description of Business .    At December 31, 2017 , we owned or operated under long-term leases, either directly or through our interest in real estate joint ventures or partnerships, a total of 204 properties, which are located in 17 states spanning the country from coast to coast. The portfolio of properties contains approximately 41.3 million  square feet of gross leasable area that is either owned by us or others.

We also owned interests in 25 parcels of land held for development that totaled approximately 18.0 million square feet.

At December 31, 2017 , we employed 281 full-time persons; our principal executive offices are located at 2600 Citadel Plaza Drive, Houston, Texas 77008; and our phone number is (713) 866-6000. We also have 10 regional offices located in various parts of the United States (“U.S.”).

Investment and Operating Strategy.     Our goal is to remain a leader in owning and operating top-tier neighborhood and community shopping centers in certain markets of the U.S. We expect to achieve this goal by:

We may either purchase, develop or lease income-producing properties in the future, and may also participate with other entities in property ownership through partnerships, joint ventures or similar types of co-ownership.

We may invest in mortgages; however, we have traditionally invested in first mortgages to real estate joint ventures or partnerships in which we own an equity interest or to obtain control over a real estate asset that we desire to own. We may also invest in securities of other issuers for the purpose, among others, of exercising control over such entities, subject to the gross income and asset tests necessary for REIT qualification.

In acquiring and developing properties, we attempt to accumulate enough properties in a geographic area to allow for the establishment of a regional office, which enables us to obtain in-depth knowledge of the market from a leasing perspective and to have easy access to the property and our tenants from a management viewpoint.

We expect to continue our focus on the future growth of the portfolio in neighborhood and community shopping centers in markets where we currently operate throughout the U.S. Our markets of interest reflect high income and job growth, as well as high barriers-to-entry. Our attention is also focused on high quality, supermarket-anchored and necessity-based centers, which may include mixed-use properties containing this type of retail component.

Diversification from both a geographic and tenancy perspective is a critical component of our operating strategy. Our largest markets are located in California, Florida and Texas, which represent 11.2%, 18.0% and 28.4%, respectively, of our total properties' gross leasable area. With respect to tenant diversification, our two largest tenants, The Kroger Co. and TJX Companies, Inc., accounted for 2.8% and 2.3%, respectively, of our total base minimum rental revenues for the year ended December 31, 2017 . No other tenant accounted for more than 1.9% of our total base minimum rental revenues. Our anchor tenants are supermarkets, value-oriented apparel/discount stores and other retailers or service providers who generally sell basic necessity-type goods and services. We believe the stability of our anchor tenants, combined with convenient locations, attractive and well-maintained properties, high quality retailers and a strong tenant mix, should ensure the long-term success of our merchants and the viability of our portfolio.

Strategically, we strive to finance our growth and working capital needs in a conservative manner, including managing our debt maturities. Our senior debt credit ratings were BBB with a projected stable outlook from Standard & Poors and Baa1 with a projected stable outlook from Moody’s Investor Services as of December 31, 2017 . We intend to maintain a conservative approach to managing our balance sheet, which, in turn, should give us many options for raising debt or equity capital when needed. At December 31, 2017 and 2016 , our ratio of earnings to combined fixed charges and preferred dividends as defined by the Securities and Exchange Commission (“SEC”), not based on funds from operations attributable to common shareholders, was 4.74 to 1 and 4.05 to 1, respectively. Our debt to total assets before depreciation ratio was 38.6% and 42.0% at December 31, 2017 and 2016 , respectively.

We have a $200 million share repurchase plan under which we may repurchase common shares of beneficial interest ("common shares") from time-to-time in open-market or privately negotiated purchases based on management's evaluation of market conditions and other factors.

Our policies with respect to the investment and operating strategies discussed above are periodically reviewed by our Board of Trust Managers and may be modified without a vote of our shareholders.

Location of Properties.     Our properties are located in 17 states, principally in the South, West Coast and Southeast Coast of the U.S. As of December 31, 2017 , we have 204 properties that were owned or operated under long-term leases, either directly or through our interest in real estate joint ventures or partnerships. Total revenues generated by our centers located in Houston and its surrounding areas was 19.6% of total revenue for the year ended December 31, 2017 , and an additional 9.2% of total revenue was generated in 2017 from centers that are located in other parts of Texas. An additional 17.5% and 16.7% , respectively, of total revenue was generated in 2017 in Florida and California. As of December 31, 2017 , we also had 25 parcels of land held for development, six of which were located in Houston and its surrounding areas and 11 of which were located in other parts of Texas. Because of our investments in Texas, including Houston and its surrounding areas, Florida and California, these economies could affect our business and operations more so than in other geographic areas.

Competition .    We compete with numerous other developers and real estate companies (both public and private), financial institutions and other investors engaged in the development, acquisition and operation of shopping centers in our trade areas. This results in competition for the acquisition of both existing income-producing properties and prime development sites.

We also compete for tenants to occupy the space that is developed, acquired and managed by our competitors. The principal competitive factors in attracting tenants in our market areas are location, price, anchor tenants and maintenance of properties. We believe our key competitive advantages include the favorable locations of our properties, the strong demographics surrounding our centers, knowledge of markets and customer bases, our ability to provide a retailer with multiple locations with quality anchor tenants and the practice of continuous maintenance and renovation of our properties.

Qualification as a Real Estate Investment Trust.     As of December 31, 2017 , we met the qualification requirements of a REIT under the Internal Revenue Code, as amended. As a result, we will not be subject to federal income tax to the extent we meet certain requirements of the Internal Revenue Code, with the exception of our taxable REIT subsidiary.

Financial Information .    Additional financial information concerning us is included in the Consolidated Financial Statements located in Item 8 herein.

ITEM 1A. Risk Factors

The risks described below could materially and adversely affect our shareholders and our results of operations, financial condition, liquidity and cash flows. In addition to these risks, our operations may also be affected by additional factors not presently known or that we currently consider immaterial to our operations.

Disruptions in the financial markets could affect our liquidity and have other adverse effects on us and the market price of our common shares of beneficial interest.

The U.S. and global equity and credit markets have experienced and may in the future experience significant price volatility, dislocations and liquidity disruptions, which could cause market prices of many stocks to fluctuate substantially and the spreads on prospective debt financings to widen considerably. These circumstances could materially impact liquidity in the financial markets, making terms for certain financings less attractive, and in certain cases result in the unavailability of certain types of financing. Uncertainties in the equity and credit markets may negatively impact our ability to access additional financing at reasonable terms or at all, which may negatively affect our ability to complete dispositions, form joint ventures or refinance our debt. A prolonged downturn in the equity or credit markets could cause us to seek alternative sources of potentially less attractive financing, and require us to adjust our business plan accordingly. In addition, these factors may make it more difficult for us to sell properties or adversely affect the price we receive for properties that we do sell, as prospective buyers may experience increased costs of financing or difficulties in obtaining financing. These events in the equity and credit markets may make it more difficult or costly for us to raise capital through the issuance of our common shares or preferred shares. These disruptions in the financial markets also may have a material adverse effect on the market value of our common shares and other adverse effects on us or the economy generally. There can be no assurances that government responses to any disruptions in the financial markets would restore consumer confidence, maintain stabilized markets or provide the availability of equity or credit financing.

Among the market conditions that may affect the value of our common shares and access to the capital markets are the following:

The volatility in the stock market can create price and volume fluctuations that may not necessarily be comparable to operating performance.

The economic performance and value of our shopping centers depend on many factors, each of which could have an adverse impact on our cash flows and operating results.

The economic performance and value of our properties can be affected by many factors, including the following:

Our properties consist primarily of neighborhood and community shopping centers and, therefore, our performance is linked to general economic conditions in the market for retail space. The market for retail space has been and could in the future be adversely affected by weakness in the national, regional and local economies where our properties are located, the adverse financial condition of some large retail companies, the ongoing consolidation in the retail sector, the excess amount of retail space in a number of markets and increasing consumer purchases through the Internet. To the extent that any of these conditions exist, they are likely to affect market rents for retail space. In addition, we may face challenges in the management and maintenance of the properties or encounter increased operating costs, such as real estate taxes, insurance and utilities, which may make our properties unattractive to tenants. A significant decrease in rental revenue and an inability to replace such revenues may adversely affect our profitability, the ability to meet debt and other financial obligations and pay dividends to shareholders.

We have properties that are geographically concentrated, and adverse economic or other conditions in that area could have a material adverse effect on us.

We are particularly susceptible to adverse economic or other conditions in markets where our properties are concentrated, including California, Florida and Texas. These adverse conditions include increased unemployment, industry slowdowns, including declining oil prices, business layoffs or downsizing, decreases in consumer confidence, relocations of businesses, changes in demographics, increases in real estate and other taxes, increases in regulations and natural disasters, any of which could have an increased material adverse effect on us than if our portfolio was more geographically diverse.

Our acquisition activities may not produce the cash flows that we expect and may be limited by competitive pressures or other factors.

We intend to acquire existing commercial properties to the extent that suitable acquisitions can be made on advantageous terms. Acquisitions of commercial properties involve risks such as:

In addition, we may not be in a position or have the opportunity in the future to make suitable property acquisitions on advantageous terms due to competition for such properties with others engaged in real estate investment. Our inability to successfully acquire new properties may have an adverse effect on our results of operations.

Turmoil in capital markets could adversely impact acquisition activities and pricing of real estate assets.

Volatility in the capital markets could impact the availability of debt financing due to numerous factors, including the tightening of underwriting standards by lenders and credit rating agencies. These factors directly affect a lender’s ability to provide debt financing as well as increase the cost of available debt financing. As a result, we may not be able to obtain debt financing on favorable terms or at all. This may result in future acquisitions generating lower overall economic returns, which may adversely affect our results of operations and dividends paid to shareholders. Furthermore, any turmoil in the capital markets could adversely impact the overall amount of capital available to invest in real estate, which may result in price or value decreases of real estate assets.

Our real estate assets may be subject to impairment charges.

Periodically, we assess whether there are any indicators that the value of our real estate assets, including any capitalized costs and any identifiable intangible assets, may be impaired. A property's value is impaired only if the estimate of the aggregate future undiscounted cash flows without interest charges to be generated by the property are less than the carrying value of the property. In estimating cash flows, we consider factors such as expected future operating income, trends and prospects, the effects of demand, competition and other factors. If we are evaluating the potential sale of an asset or development/redevelopment alternatives, the undiscounted future cash flows consider the most likely course of action at the balance sheet date based on current plans, intended holding periods and available market information. Determining whether a property is impaired and, if impaired, the amount of write-down to fair value requires a significant amount of judgment by management and is based on the best information available to management at the time of evaluation. If market conditions deteriorate or management’s plans for certain properties change, additional write-downs could be required in the future, and any future impairment could have a material adverse effect on our results of operations in the period in which the charge is taken.

Reduction of rental income would adversely affect our profitability, our ability to meet our debt obligations and our ability to pay dividends to our shareholders.

The substantial majority of our income is derived from rental income from real property. As a result, our performance depends on our ability to collect rent from tenants. Our income and funds to pay dividends would be negatively affected if a significant number of our tenants, or any of our major tenants (as discussed in more detail below):

Any of these actions could result in the termination of the tenants’ lease and the loss of rental income attributable to the terminated leases. In addition, lease terminations by an anchor tenant or a failure by that anchor tenant to occupy the premises could also result in lease terminations or reductions in rent by other tenants in the same shopping center under the terms of some leases. In these events, we cannot be sure that any tenant whose lease expires will renew that lease or that we will be able to re-lease space on economically advantageous terms. Furthermore, certain costs remain fixed even though a property may not be fully occupied. The loss of rental revenues from a number of our tenants and our inability to replace such tenants, particularly in the case of a substantial tenant with leases in multiple locations, may adversely affect our profitability, our ability to meet debt and other financial obligations and our ability to pay dividends to the shareholders.

Adverse effects on the success and stability of our anchor tenants, could lead to reductions of rental income.

Our rental income could be adversely affected in the event of a downturn in the business, or the bankruptcy or insolvency of, any anchor store or anchor tenant. Anchor tenants generally occupy large amounts of square footage, pay a significant portion of the total rents at a property and contribute to the success of other tenants by drawing significant numbers of customers to a property. The closing of one or more anchor stores at a property could adversely affect that property and result in lease terminations or reductions in rent from other tenants, whose leases may permit termination or rent reduction in those circumstances or whose own operations may suffer as a result. Furthermore, tenant demand for certain of our anchor spaces may decrease, and as a result, we may see an increase in vacancy and/or a decrease in rents for those spaces, which could have a negative impact to our rental income.

Adverse effects resulting from a shift in retail shopping from brick and mortar stores to online shopping may impact our operating results.

Online sales for many retailers has become a fundamental part of their business in addition to operating brick and mortar stores. Additionally, online sales from companies without physical stores has increased significantly. Although many of the retailers operating in our properties sell groceries, value-oriented apparel and other necessity-based type goods or provide services, including entertainment and dining, the shift to online shopping may cause certain of our tenants to reduce the size or number of their retail locations in the future. As a result, this could negatively affect our ability to lease space and our operating results.

We face significant competition in the leasing market, which may decrease or prevent increases in the occupancy and rental rates of our properties.

We compete with numerous developers, owners and operators of retail properties, many of which own properties similar to, and in the same market sectors as, our properties. If our competitors offer space at rental rates below current market rates, or below the rental rates we currently charge our tenants, we may lose existing or potential tenants, or we may be forced to reduce rental rates in order to attract new tenants and retain existing tenants when their leases expire.

Also, if our competitors develop additional retail properties in locations near our properties, there may be increased competition for customer traffic and creditworthy tenants, which may result in fewer tenants or decreased cash flows from tenants, or both, and may require us to make capital improvements to properties that we would not have otherwise made. Our tenants also face increasing competition from other forms of marketing of goods, such as direct mail and Internet marketing, which may decrease cash flow from such tenants. As a result, our financial condition and our ability to pay dividends to our shareholders may be adversely affected.

We may be unable to collect balances due from tenants in bankruptcy.

A tenant that files for bankruptcy protection may not continue to pay us rent. A bankruptcy filing by or relating to one of our tenants or a lease guarantor would bar all efforts by us to collect pre-bankruptcy debts from the tenant or the lease guarantor, or their property, unless the bankruptcy court permits us to do so. A tenant or lease guarantor bankruptcy could delay our efforts to collect past due balances under the relevant leases and could ultimately preclude collection of these sums. If a lease is rejected by a tenant in bankruptcy, we would have only a general unsecured claim for damages. As a result, it is likely that we would recover substantially less than the full value of any unsecured claims it holds, if at all.

Our development, redevelopment and construction activities could adversely affect our operating results.

We intend to continue the selective development, redevelopment and construction of retail properties in accordance with our development and underwriting policies as opportunities arise. Our development, redevelopment and construction activities include risks that:

Additionally, the time frame required for development, redevelopment, construction and lease-up of these properties means that we may have to wait years for a significant cash return. If any of the above events occur, the development and redevelopment of properties may hinder our growth and have an adverse effect on our results of operations, including additional impairment charges. Also, new development activities, regardless of whether or not they are ultimately successful, typically require substantial time and attention from management.

There is a lack of operating history with respect to any recent acquisitions and redevelopment or development of properties, and we may not succeed in the integration or management of additional properties.

These properties may have characteristics or deficiencies currently unknown to us that affect their value or revenue potential. It is also possible that the operating performance of these properties may decline under our management. We also may not have the experience in developing and managing mixed-use properties and may need to rely on external resources which may not perform as we expected. As we acquire additional properties, we will be subject to risks associated with managing new properties, including lease-up and tenant retention. In addition, our ability to manage our growth effectively will require us to successfully integrate any new acquisitions into our existing management structure. We may not succeed with this integration or effectively manage additional properties. Also, newly acquired properties may not perform as expected.

Real estate property investments are illiquid, and therefore, we may not be able to dispose of properties when desirable or on favorable terms.

Real estate property investments generally cannot be disposed of quickly. In addition, the Internal Revenue Code imposes restrictions on the ability of a REIT to dispose of properties that are not applicable to other types of real estate companies. Our ability to dispose of properties on advantageous terms depends on factors beyond our control, including competition from other sellers and the availability of attractive financing for potential buyers of our properties, and we cannot predict the various market conditions affecting real estate investments that will exist at any particular time in the future. Therefore, we may not be able to quickly vary our portfolio in response to economic or other conditions promptly or on favorable terms, which could cause us to incur extended losses and reduce our cash flows and adversely affect dividends paid to shareholders.

As part of our capital recycling program, we intend to sell our non-core assets and may not be able to recover our investments, which may result in losses to us.

There can be no assurance that we will be able to recover the current carrying amount of all of our owned and partially owned non-core properties and investments in the future. Our failure to do so would require us to recognize impairment charges in the period in which we reached that conclusion, which could adversely affect our business, financial condition, operating results and cash flows.

Credit ratings may not reflect all the risks of an investment in our debt or equity securities and rating changes could adversely effect our revolving credit facility.

Our credit ratings are an assessment by rating agencies of our ability to pay our debts when due. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of our debt. Credit ratings may be revised or withdrawn at any time by the rating agency at its sole discretion. Additionally, our revolving credit facility fees are based on our credit ratings. We do not undertake any obligation to maintain the ratings or to advise holders of our debt of any change in ratings. Each agency's rating should be evaluated independently of any other agency's rating.

There can be no assurance that we will be able to maintain our current credit ratings. Adverse changes in our credit ratings could impair our ability to obtain additional debt and equity financing on favorable terms, if at all, and could significantly reduce the market price of our publicly-traded securities.

Our cash flows and operating results could be adversely affected by required payments of debt or related interest and other risks of our debt financing.

We are generally subject to risks associated with debt financing. These risks include:

If a property is mortgaged to secure payment of indebtedness and we cannot make the mortgage payments, we may have to surrender the property to the lender with a consequent loss of any prospective income and equity value from such property. Any of these risks can place strains on our cash flows, reduce our ability to grow and adversely affect our results of operations.

We may be adversely affected by changes in LIBOR reporting practices or the method in which LIBOR is determined.

As of December 31, 2017, we had outstanding approximately $217.9 million of debt that was indexed to the London Interbank Offered Rate (“LIBOR”); however, we have swapped $200 million of that amount to a fixed rate. On July 27, 2017, the Financial Conduct Authority (the “FCA”) announced its intention to phase out LIBOR rates by the end of 2021. It is not possible to predict the further effect of the rules of the FCA, any changes in the methods by which LIBOR is determined, or any other reforms to LIBOR that may be enacted in the United Kingdom, the European Union or elsewhere. Any such developments may cause LIBOR to perform differently than in the past, or cease to exist. In addition, any other legal or regulatory changes made by the FCA, ICE Benchmark Administration Limited, the European Money Markets Institute (formerly Euribor-EBF), the European Commission or any other successor governance or oversight body, or future changes adopted by such body, in the method by which LIBOR is determined or the transition from LIBOR to a successor benchmark may result in, among other things, a sudden or prolonged increase or decrease in LIBOR, a delay in the publication of LIBOR, and changes in the rules or methodologies in LIBOR, which may discourage market participants from continuing to administer or to participate in LIBOR’s determination, and, in certain situations, could result in LIBOR no longer being determined and published. If a published U.S. dollar LIBOR rate is unavailable after 2021, the interest rates on our debt which is indexed to LIBOR will be determined using various alternative methods, any of which may result in interest obligations which are more than or do not otherwise correlate over time with the payments that would have been made on such debt if U.S. dollar LIBOR was available in its current form. Further, the same costs and risks that may lead to the discontinuation or unavailability of U.S. dollar LIBOR may make one or more of the alternative methods impossible or impracticable to determine. Any of these proposals or consequences could have a material adverse effect on our financing costs.

Rising interest rates could increase our borrowing costs, thereby adversely affecting our cash flows and the amounts available for dividends to our shareholders, and decrease our share price, if investors seek higher yields through other investments.

We have indebtedness with interest rates that vary depending on market indices. Also, our credit facilities bear interest at variable rates. We may incur variable-rate debt in the future. Increases in interest rates on variable-rate debt would increase our interest expense, which would negatively affect net income and cash available for payment of our debt obligations and dividends to shareholders. In addition, an increase in interest rates could adversely affect the market value of our outstanding debt, as well as increase the cost of refinancing and the issuance of new debt or securities. An environment of rising interest rates could also lead holders of our securities to seek higher yields through other investments, which could adversely affect the market price of our shares. One of the factors which may influence the price of our shares in public markets is the annual dividend rate we pay as compared with the yields on alternative investments.

Our financial condition could be adversely affected by financial covenants.

Our credit facilities and public debt indentures under which our indebtedness is, or may be, issued contain certain financial and operating covenants, including, among other things, certain coverage ratios, as well as limitations on our ability to incur secured and unsecured indebtedness, restrictions on our ability to sell all or substantially all of our assets and engage in mergers and consolidations and certain acquisitions. These covenants could limit our ability to obtain additional funds needed to address cash shortfalls or pursue growth opportunities or transactions that would provide substantial return to our shareholders. In addition, a breach of these covenants could cause a default under or accelerate some or all of our indebtedness, which could have a material adverse effect on our financial condition.

Property ownership through real estate partnerships and joint ventures could limit our control of those investments and reduce our expected return.

Real estate partnership or joint venture investments may involve risks not otherwise present for investments made solely by us, including the possibility that our partner or co-venturer might become bankrupt, that our partner or co-venturer might at any time have different interests or goals than us, and that our partner or co-venturer may take action contrary to our instructions, requests, policies or objectives. Other risks of joint venture investments could include impasse on decisions, such as a sale or refinance, because neither our partner or co-venturer nor we would have full control over the partnership or joint venture. These factors could limit the return that we receive from those investments or cause our cash flows to be lower than our estimates.

Volatility in market and economic conditions may impact our partners’ ability to perform in accordance with our real estate joint venture and partnership agreements resulting in a change in control or the liquidation plans of its underlying properties.

Changes in control of our investments could result if any reconsideration events occur, such as amendments to our real estate joint venture and partnership agreements, changes in debt guarantees or changes in ownership due to required capital contributions. Any changes in control will result in the revaluation of our investments to fair value, which could lead to an impairment. We are unable to predict whether, or to what extent, a change in control may result or the impact of adverse market and economic conditions may have to our partners.

If we fail to qualify as a REIT in any taxable year, we will be subject to U.S. federal income tax as a regular corporation and could have significant tax liability.

We intend to operate in a manner that allows us to qualify as a REIT for U.S. federal income tax purposes. However, REIT qualification requires us to satisfy numerous requirements (some on an annual or quarterly basis) established under highly technical and complex provisions of the Internal Revenue Code, for which there are a limited number of judicial or administrative interpretations. Our status as a REIT requires an analysis of various factual matters and circumstances that are not entirely within our control. Accordingly, it is not certain we will be able to qualify and remain qualified as a REIT for U.S. federal income tax purposes. Even a technical or inadvertent violation of the REIT requirements could jeopardize our REIT qualification. If we fail to qualify as a REIT in any tax year, then:

Even if we remain qualified as a REIT, we may face other tax liabilities that reduce our cash flow. We may also be subject to certain U.S. federal, state and local taxes on our income and property either directly or at the level of our subsidiaries. Any of these taxes would decrease cash available for dividends to our shareholders.

Tax laws have recently changed and may continue to change at any time, and any such legislative or other actions could have a negative effect on us.

The Tax Cuts and Jobs Act of 2017 ("Tax Act") was signed into law on December 22, 2017. The law includes significant changes to the U.S. corporate income tax system, including a Federal corporate rate reduction from 35% to 21% for non-REIT "C" corporations, which may cause investors to perceive investments in REITs to be less attractive than investments in the stock of non-REIT “C” corporations. The law also includes limitations on the deductibility of executive compensation, which may result in our being required to pay higher dividends to continue to qualify as a REIT at a time and in an amount that otherwise may not be in our and our shareholders’ best interests.

In addition, tax laws remain under constant review by persons involved in the legislative process, at the Internal Revenue Service ("IRS") and the U.S. Department of the Treasury, and by various state and local tax authorities. Changes to tax laws, regulations, or administrative interpretations, which may be applied retroactively, could adversely affect us in a number of additional ways, including making it more difficult or more costly for us to qualify as a REIT or decreasing real estate values generally.

We cannot predict the full impact of the Tax Act or whether, when, in what forms, or with what effective dates, the tax laws, regulations, and administrative interpretations applicable to us or our shareholders may be further changed.

Compliance with REIT requirements may negatively affect our operating decisions.

To maintain our status as a REIT for U.S. federal income tax purposes, we must meet certain requirements, on an ongoing basis, including requirements regarding our sources of income, the nature and diversification of our assets, the amounts we distribute to our shareholders and the ownership of our common shares. We may also be required to pay dividends to our shareholders when we do not have funds readily available for distribution or at times when our funds are otherwise needed to fund capital expenditures or debt service obligations.

As a REIT, we must distribute at least 90% of our annual net taxable income (excluding net capital gains) to our shareholders. To the extent that we satisfy this distribution requirement, but distribute less than 100% of our net taxable income, we will be subject to U.S. federal corporate income tax on our undistributed taxable income. From time to time, we may generate taxable income greater than our income for financial reporting purposes, or our net taxable income may be greater than our cash flow available for distribution to our shareholders. If we do not have other funds available in these situations, we could be required to borrow funds, sell a portion of our securities at unfavorable prices or find other sources of funds in order to meet the REIT distribution requirements.

Our common shares dividend policy may change in the future.

The timing, amount and composition of any future dividends to our common shareholders will be at the sole discretion of our Board of Trust Managers and will depend upon a variety of factors as to which no assurance can be given. Our ability to make dividends to our common shareholders depends, in part, upon our operating results, overall financial condition, the performance of our portfolio (including occupancy levels and rental rates), our capital requirements, access to capital, our ability to qualify for taxation as a REIT and general business and market conditions. Any change in our dividend policy could have an adverse effect on the market price of our common shares.

Our declaration of trust contains certain limitations associated with share ownership.

To maintain our status as a REIT, our declaration of trust prohibits any individual from owning more than 9.8% of our outstanding common shares. This restriction is likely to discourage third parties from acquiring control without the consent of our Board of Trust Managers, even if a change in control were in the best interests of our shareholders.

Also, our declaration of trust requires the approval of the holders of 80% of our outstanding common shares and the approval by not less than 50% of the outstanding common shares not owned by any related person (a person owning more than 50% of our common shares) to consummate a business transaction such as a merger. There are certain exceptions to this requirement; however, the 80% approval requirement could make it difficult for us to consummate a business transaction even if it is in the best interests of our shareholders.

There may be future dilution of our common shares.

Our declaration of trust authorizes our Board of Trust Managers to, among other things, issue additional common or preferred shares or securities convertible or exchangeable into equity securities, without shareholder approval. We may issue such additional equity or convertible securities to raise additional capital. The issuance of any additional common or preferred shares or convertible securities could be substantially dilutive to holders of our common shares. Moreover, to the extent that we issue restricted shares, options, or warrants to purchase our common shares in the future and those options or warrants are exercised or the restricted shares vest, our shareholders may experience further dilution. Holders of our common shares have no preemptive rights that entitle them to purchase a pro rata share of any offering of shares of any class or series and, therefore, such sales or offerings could result in increased dilution to our shareholders.

We may issue debt and equity securities or securities convertible into equity securities, any of which may be senior to our common shares as to distributions and in liquidation, which could negatively affect the value of our common shares.

In the future, we may attempt to increase our capital resources by entering into unsecured or secured debt or debt-like financings, or by issuing additional debt or equity securities, which could include issuances of medium-term notes, senior notes, subordinated notes, secured debt, guarantees, preferred shares, hybrid securities, or securities convertible into or exchangeable for equity securities. In the event of our liquidation, our lenders and holders of our debt and, if any, preferred securities would receive distributions of our available assets before distributions to the holders of our common shares. Because any decision to incur debt and issue securities in future offerings may be influenced by market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing, or nature of our future financings. Further, market conditions could require us to accept less favorable terms for the issuance of our securities in the future.

Our declaration of trust contains certain limitations that make removal of our Trust Managers difficult, which could limit our shareholders ability to effect changes to our management.

Our declaration of trust provides that a Trust Manager may only be removed for cause upon the affirmative vote of holders of two-thirds of the total votes authorized to be cast by shares outstanding and entitled to be voted. Vacancies may be filled by either a majority of the remaining Trust Managers or elected by the vote of holders of at least two-thirds of the outstanding shares at the Annual Meeting or a special meeting of the shareholders. These requirements provide limitations to make changes in our management by removing and replacing Trust Managers and may prevent a change of control that is in the best interests of our shareholders.

Loss of our key personnel could adversely affect the value of our common shares and operations.

We are dependent on the efforts of our key executive personnel. A significant number of persons in our management group are eligible for retirement. Although we believe qualified replacements could be found for these key executives and other members of our management group, the loss of their services could adversely affect the value of our common shares and operations.

Changes in accounting standards may adversely impact our reported financial condition and results of operations.

The Financial Accounting Standards Board (“FASB”), in conjunction with the SEC, continually engages in projects to evaluate additions or changes to current accounting standards which could impact how we currently account for our material transactions. We believe that these and other potential proposals could have varying degrees of impact on us ranging from minimal to material. At this time, we are unable to predict with certainty which, if any, proposals may be passed or what level of impact any such proposal could have on us, except as disclosed in Item 8.

We could be subject to litigation that may negatively impact our cash flows, financial condition and results of operations.

From time to time, we may be a defendant in lawsuits and regulatory proceedings relating to our business. Due to the inherent uncertainties of litigation and regulatory proceedings, we cannot accurately predict the ultimate outcome of any such litigation or proceedings. We could experience a negative impact to our cash flows, financial condition and results of operations due to an unfavorable outcome.

Compliance with certain laws and governmental rules and regulations may require us to make unintended expenditures that adversely affect our cash flows.

All of our properties are required to comply with certain laws and governmental rules and regulations, including the Americans with Disabilities Act, fire and safety regulations, building codes and other land use regulations, as they may be in effect or adopted by governmental agencies and bodies and become applicable to our properties. We may be required to make substantial capital expenditures to comply with those requirements, and these expenditures could have a material adverse effect on our ability to meet the financial obligations and pay dividends to our shareholders.

An uninsured loss or a loss that exceeds the policies on our properties could subject us to lost capital or revenue on those properties.

Under the terms and conditions of the leases currently in force on our properties, tenants generally are required to indemnify and hold us harmless from liabilities resulting from injury to persons, air, water, land or property, on or off the premises, due to activities conducted on the properties, except for claims arising from our negligence or intentional misconduct or that of our agents. Tenants are generally required, at the tenant’s expense, to obtain and keep in full force during the term of the lease, liability and tenant's property damage insurance policies. We have obtained comprehensive liability, casualty, property, flood, earthquake, environmental and rental loss insurance policies on our properties. All of these policies may involve substantial deductibles and certain exclusions. In addition, we cannot assure the shareholders that the tenants will properly maintain their insurance policies or have the ability to pay the deductibles. Should a loss occur that is uninsured or in an amount exceeding the combined aggregate limits for the 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 the properties, which could have a material adverse effect on our operating results and financial condition, as well as our ability to pay dividends to the shareholders.

We may be subject to liability under environmental laws, ordinances and regulations.

Under various federal, state and local laws, ordinances and regulations, we may be considered an owner or operator of real property or have arranged for the disposal or treatment of hazardous or toxic substances. As a result, we may become liable for the costs of disposal or treatment of hazardous or toxic substances released on or in our property. We may also be liable for certain other potential costs that could relate to hazardous or toxic substances (including governmental fines and injuries to persons and property). We may incur such liability whether or not we knew of, or were responsible for, the presence of such hazardous or toxic substances.

Natural disasters and severe weather conditions could have an adverse effect on our cash flow and operating results.

Changing weather patterns and climatic conditions, such as global warming, may have added to the unpredictability and frequency of natural disasters in some parts of the world and created additional uncertainty as to future trends and exposures. Our operations are located in many areas that have experienced and may in the future experience natural disasters and severe weather conditions such as hurricanes, tornadoes, earthquakes, droughts, floods and fires. The occurrence of natural disasters or severe weather conditions can delay new development and redevelopment projects, increase investment costs to repair or replace damaged properties, increase future property insurance costs, and negatively impact the tenant demand for lease space. Additionally, these weather conditions may also disrupt our tenants business, which could affect the ability of some tenants to pay rent and may reduce the willingness of residents to remain in or move to the affected area. Intense weather conditions during the last decade have caused our cost of property insurance to increase significantly. If insurance is unavailable to us or is unavailable on acceptable terms, or if our insurance is not adequate to cover business interruption or losses from these events, our earnings, liquidity or capital resources could be adversely affected.

Our business and operations would suffer in the event of system failures.

Despite the implementation of security measures and the existence of a disaster recovery and business continuity plans for our internal information technology systems, our systems are vulnerable to damages from any number of sources, including computer viruses, unauthorized access, energy blackouts, natural disasters, terrorism, war and telecommunication failures. Any system failure or accident that causes interruptions in our operations could result in a material disruption to our business. We may also incur additional costs to remedy damages caused by such disruptions.

We face risks relating to cybersecurity attacks, loss of confidential information and other business disruptions.

Our business is at risk from and may be impacted by cybersecurity attacks, including attempts to gain unauthorized access to our confidential data and other electronic security breaches. Such cybersecurity attacks can range from individual attempts to gain unauthorized access to our information technology systems to more sophisticated security threats. In addition to our own information technology systems, third parties have been engaged to provide information technology services relating to several key business functions, such as payroll, human resources, electronic communications and certain finance functions. While we and such third parties employ a number of measures to prevent, detect and mitigate these threats including a defense in depth strategy of firewalls, intrusion sensors, malware detection, password protection, backup servers, user training and periodic penetration testing, there is no guarantee such efforts will be successful in preventing a cybersecurity attack. As our reliance on technology has increased, so have the risks posed to our systems, both internal and those we have outsourced. Cybersecurity incidents could compromise the confidential information of our tenants, employees and third-party vendors and disrupt and affect the efficiency of our business operations.

None.

ITEM 2. Properties

At December 31, 2017 , we owned or operated under long-term leases, either directly or through our interest in real estate joint ventures or partnerships, a total of 204 centers, primarily neighborhood, community and power shopping centers, which are located in 17 states spanning the country from coast to coast with approximately 41.3 million square feet of gross leasable area. Our centers are located principally in the South, West Coast and Southeast Coast of the U.S. with concentrations in California, Florida, and Texas. We also owned interests in 25 parcels of land that totaled approximately 18.0 million square feet at December 31, 2017 of which approximately 17.7 million square feet of land may be used for new development or sold, and the remaining is adjacent to our existing operating centers, which may be used for expansion of those centers.

In 2017 , no single center accounted for more than 7.3% of our total assets or 3.3% of base minimum rental revenues. The five largest centers, in the aggregate, represented approximately 11.1% of our base minimum rental revenues for the year ended December 31, 2017 ; otherwise, none of the remaining centers accounted for more than 1.8% of our base minimum rental revenues during the same period.

Our centers are designed to attract local area customers and are typically anchored by a supermarket or other national tenants (such as Kroger, HEB or T.J. Maxx). The centers are primarily neighborhood and community shopping centers that often include discounters, value-oriented retailers and specialty grocers as additional anchors or tenants, and typically range in size from 50,000 to 600,000 square feet of building area. Very few of the centers have climate-controlled common areas, but are designed to allow retail customers to park their automobiles in close proximity to any retailer in the center. Our centers are customarily constructed of masonry, steel and glass, and all have lighted, paved parking areas, which are typically landscaped with berms, trees and shrubs. They are generally located at major intersections in close proximity to neighborhoods that have existing populations sufficient to support retail activities of the types conducted in our centers.

We actively embrace various initiatives that support the future of environmentally friendly shopping centers. Our primary areas of focus include energy efficiency, waste recycling, water conservation and construction/development best practices. We recognize there are economic, environmental and social implications associated with the full range of our sustainability efforts, and that a commitment to incorporating sustainable practices will add long-term value to our centers.

As of December 31, 2017 , the weighted average occupancy rate for our centers was 94.8% compared to 94.3% as of December 31, 2016 . The average base rent per square foot was approximately $18.69 in 2017 , $17.93 in 2016 , $16.92 in 2015 , $16.24 in 2014 and $15.66 in 2013 for our centers.

We have approximately 5,400 separate leases with 3,700 different tenants. Included among our top revenue-producing tenants are: The Kroger Co., TJX Companies, Inc., Ross Stores, Inc., H-E-B Grocery Company, LP, Albertsons Companies, Inc., Office Depot, Inc., PetSmart, Inc., Bed, Bath & Beyond Inc., 24 Hour Fitness Worldwide, Inc. and Whole Foods Market, Inc. The diversity of our tenant base is also evidenced by the fact that our largest tenant, The Kroger Co., accounted for only 2.8% of base minimum rental revenues during 2017 .

New Development

At December 31, 2017 , we had three projects in various stages of development that were partially or wholly owned. We have funded $140.4 million through December 31, 2017 on these projects. We estimate our aggregate net investment upon completion to be $363.1 million . These projects are forecasted to have an average stabilized return on investment of approximately 5.5% when completed. Effective January 1, 2017, we stabilized a development in White Marsh, Maryland, moving it to our operating property portfolio, which added 136,000 square feet to the portfolio at an estimated cost per square foot of $337.52. This development was 100% leased with an investment of $46 million and an 8% yield.

Upon completion, the estimated costs and square footage to be added to the portfolio for the three projects are as follows:

GLA includes 4.5 million square feet of our partners’ ownership interest in these properties and 10.4 million square feet not owned or managed by us. Additionally, encumbrances on our properties total $.4 billion . See Schedule III for additional information.

The following table is a detailed list of centers by state and includes our share of both consolidated and unconsolidated real estate partnerships and joint ventures as of December 31, 2017 :
