DOCUMENTS INCORPORATED BY REFERENCE:

This report combines the annual reports on Form 10-K for the year ended December 31, 20202021 of Essex Property Trust, Inc., a Maryland corporation, and Essex Portfolio, L.P., a Delaware limited partnership of which Essex Property Trust, Inc. is the sole general partner.

Unless stated otherwise or the context otherwise requires, references to the "Company," "we," "us," or "our" mean collectively Essex Property Trust, Inc. and those entities/subsidiaries owned or controlled by Essex Property Trust, Inc., including Essex Portfolio, L.P., and references to the "Operating Partnership," or "EPLP" mean Essex Portfolio, L.P. and those entities/subsidiaries owned or controlled by Essex Portfolio, L.P. Unless stated otherwise or the context otherwise requires, references to "Essex" mean Essex Property Trust, Inc., not including any of its subsidiaries.

Essex operates as a self-administered and self-managed real estate investment trust ("REIT"), and is the sole general partner of the Operating Partnership. As of December 31, 2020,2021, Essex owned approximately 96.6% of the ownership interest in the Operating Partnership with the remaining 3.4% interest owned by limited partners. As the sole general partner of the Operating Partnership, Essex has exclusive control of the Operating Partnership's day-to-day management.

The Company is structured as an umbrella partnership REIT ("UPREIT") and Essex contributes all net proceeds from its various equity offerings to the Operating Partnership. In return for those contributions, Essex receives a number of Operating Partnership limited partnership units ("OP Units," and the holders of such OP Units, "Unitholders") equal to the number of shares of common stock it has issued in the equity offerings. Contributions of properties to the Company can be structured as tax-deferred transactions through the issuance of OP Units, which is one of the reasons why the Company is structured in the manner outlined above. Based on the terms of the Operating Partnership's partnership agreement, OP Units can be exchanged into Essex common stock on a one-for-one basis. The Company maintains a one-for-one relationship between the OP Units issued to Essex and shares of common stock.

The Company believes that combining the reports on Form 10-K of Essex and the Operating Partnership into this single report provides the following benefits:

Management operates Essex and the Operating Partnership as one business. The management of Essex consists of the same members as the management of the Operating Partnership.

All of the Company's property ownership, development, and related business operations are conducted through the Operating Partnership and Essex has no material assets, other than its investment in the Operating Partnership. Essex's primary function is acting as the general partner of the Operating Partnership. As general partner with control of the Operating Partnership, Essex consolidates the Operating Partnership for financial reporting purposes. Therefore, the assets and liabilities of Essex and the Operating Partnership are the same on their respective financial statements. Essex also issues equity from time to time and guarantees certain debt of the Operating Partnership, as disclosed in this report. The Operating Partnership holds substantially all of the assets of the Company, including the Company's ownership interests in its co-investments. The Operating Partnership conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for the net proceeds from equity offerings by the Company, which are contributed to the capital of the Operating Partnership in exchange for OP Units (on a one-for-one share of common stock per OP Unit basis), the Operating Partnership generates all remaining capital required by the Company's business. These sources of capital include the Operating Partnership's working capital, net cash provided by operating activities, borrowings under its revolving credit facilities, the issuance of secured and unsecured debt and equity securities and proceeds received from disposition of certain properties and co-investments.

The Company believes it is important to understand the few differences between Essex and the Operating Partnership in the context of how Essex and the Operating Partnership operate as a consolidated company. Stockholders' equity, partners' capital and noncontrolling interest are the main areas of difference between the consolidated financial statements of Essex and those of the Operating Partnership. The limited partners of the Operating Partnership are accounted for as partners' capital in the Operating Partnership's consolidated financial statements and as noncontrolling interest in Essex's consolidated financial statements. The noncontrolling interest in the Operating Partnership's consolidated financial statements include the interest of unaffiliated partners in various consolidated partnerships and co-investment partners. The noncontrolling interest in Essex's

consolidated financial statements include (i) the same noncontrolling interest as presented in the Operating Partnership’s consolidated financial statements and (ii) OP Unitholders. The differences between stockholders' equity and partners' capital result from differences in the equity issued at Essex and Operating Partnership levels.

To help investors understand the significant differences between Essex and the Operating Partnership, this report on Form 10-K provides separate consolidated financial statements for Essex and the Operating Partnership; a single set of consolidated notes to such financial statements that includes separate discussions of stockholders' equity or partners' capital, and earnings per share/unit, as applicable; and a combined Management's Discussion and Analysis of Financial Condition and Results of Operations.

This report on Form 10-K also includes separate Part II, Item 9A. Controls and Procedures sections and separate Exhibits 31 and 32 certifications for each of Essex and the Operating Partnership in order to establish that the requisite certifications have been made and that Essex and the Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934 (the "Exchange Act") and 18 U.S.C. §1350.

In order to highlight the differences between Essex and the Operating Partnership, the separate sections in this report on Form 10-K for Essex and the Operating Partnership specifically refer to Essex and the Operating Partnership. In the sections that combine disclosure of Essex 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 directly or indirectly enters into contracts and co-investments and holds assets and debt, reference to the Company is appropriate because the Company is one business and the Company operates that business through the Operating Partnership. The separate discussions of Essex 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.

The information furnished in the accompanying consolidated balance sheets, statements of income, comprehensive income, equity, capital, and cash flows of the Company and the Operating Partnership reflect all adjustments which are, in the opinion of management, necessary for a fair presentation of the aforementioned consolidated financial statements for the periods and are normal and recurring in nature, except as otherwise noted.

The accompanying consolidated financial statements should be read in conjunction with the notes to such consolidated financial statements and Management's Discussion and Analysis of Financial Condition and Results of Operations herein.

The following is a summary of the principal risks that could adversely affect our business, operating results, cash flows and financial conditions.

Essex Property Trust, Inc. ("Essex"), a Maryland corporation, is an S&P 500 company that operates as a self-administered and self-managed real estate investment trust ("REIT"). Essex owns all of its interest in its real estate and other investments directly or indirectly through Essex Portfolio, L.P.

In this report, the terms the "Company," "we," "us," and "our" also refer to Essex Property Trust, Inc., the Operating Partnership and those entities/subsidiaries owned or controlled by Essex and/or the Operating Partnership.

Essex has elected to be treated as a REIT for federal income tax purposes, commencing with the year ended December 31, 1994. Essex completed its initial public offering on June 13, 1994. In order to maintain compliance with REIT tax rules, the Company utilizes taxable REIT subsidiaries for various revenue generating or investment activities. All taxable REIT subsidiaries are consolidated by the Company for financial reporting purposes.

The Company is engaged primarily in the ownership, operation, management, acquisition, development and redevelopment of predominantly apartment communities, located along the West Coast of the United States. As of December 31, 2020,2021, the Company owned or had ownership interests in 246252 operating apartment communities, aggregating 60,27261,911 apartment homes, excluding the Company's ownership in preferred equity co-investments, loan investments, onethree operating commercial building,buildings, and a development pipeline comprised of threeone consolidated projectsproject and threeone unconsolidated joint venture projectsproject aggregating 1,853371 apartment homes (collectively, the "Portfolio").

The information contained on the Company's website shall not be deemed to be incorporated into this report.

The following is a discussion of the Company’s business strategies in regards to real estate investment and management.

Recognizing that all real estate markets are cyclical, the Company regularly evaluates the results of its regional economic, and local market research, and adjusts the geographic focus of its portfolio accordingly. The Company seeks to increase its portfolio allocation in markets projected to have the strongest local economies and to decrease allocations in markets projected to have declining economic conditions. Likewise, the Company also seeks to increase its portfolio allocation in markets that have attractive property valuations and to decrease allocations in markets that have inflated valuations and low relative yields.

Acquisitions are an important component of the Company’s business plan. The tabletables below summarizessummarize acquisition activity for the year ended December 31, 20202021 ($ in millions):

As part of its strategic plan to own quality real estate in supply-constrained markets, the Company continually evaluates all of its communities and sells those which no longer meet its strategic criteria. The Company may use the capital generated from the dispositions to invest in higher-return communities, or other real estate investments or to repay debts.fund other commitments. The Company believes that the sale of these communities will not have a material impact on its future results of operations or cash flows nor will their sale materially affect its ongoing operations. In general, the Company seeks to offset the dilutive impact on long-term earnings and funds from operations from these dispositions through the positive impact of reinvestment of proceeds.

In June 2020,For the year ended December 31, 2021, the Company completed a portfolio sale which consistedsold four communities consisting of two apartment communities with 429912 apartment homes One South Market and Museum Park, both located in San Jose, CA, for a total contract price of $232.0 million, resulting in a gain of $16.6 million for the Company.approximately $330.0 million.

The Company defines development projects as new communities that are being constructed, or are newly constructed and are in a phase of lease-up and have not yet reached stabilized operations. As of December 31, 2020,2021, the Company's development pipeline was comprised of threeone consolidated projectsproject under development and threeone unconsolidated joint venture projectsproject under development aggregating 1,853371 apartment homes, with total incurred costs of $948.0$156.0 million, and estimated remaining project costs of approximately $174.0$61.0 million, $118.0$32.6 million of which represents the Company's share of estimated remaining costs, for total estimated project costs of $1.1 billion.

The Company defines predevelopment projects as proposed communities in negotiation or in the entitlement process with an expected high likelihood of becoming entitled development projects. As of December 31, 2020,2021, the Company had various consolidated predevelopment projects. The Company may also acquire land for future development purposes or sale.

The following table sets forth information regarding the Company’s development pipeline ($ in millions):

The 2021 ATM Program replaces the Company’s prior equity distribution agreement entered into in September 2018 (the “2018 ATM Program”), which was terminated upon the establishment of the 2021 ATM Program. During the year ended December 31, 2020,2021, the Company did not issue any shares of common stock through its equity distribution program.the 2021 ATM Program or through the 2018 ATM Program.

The Company has entered into, and may continue in the future to enter into, joint ventures or partnerships (including limited liability companies) through which we own an indirect economic interest in less than 100% of the community or land or other investments owned directly by the joint venture or partnership. For each joint venture the Company holds a non-controlling interest in the venture and earns customary management fees and may earn development fees, asset property management fees, and a promote interest.

The Company has also made, and may continue in the future to make, preferred equity investments in various multifamily development projects. The Company earns a preferred rate of return on these investments.

The Company is headquartered in San Mateo, CA, and has regional offices in Woodland Hills, CA; Irvine, CA; San Diego, CA and Bellevue, WA. As of December 31, 2020,2021, the Company had 1,7991,757 employees, ninety-eightninety-nine percent (98%(99%) of which were full-time employees, and of which 1,4831,382 employees worked in operations and 316375 were employed in the corporate offices. The Company's mission is to create quality communities in premier locations and it is critical to the Company's mission that it attracts, trains and retains a talented and diverse team by providing a better place to work and significant opportunities for professional growth. The Company's culture supports its mission and is guided by its core values: to act with integrity, to care about what matters, to do right with urgency, to lead at every level and to seek fairness. The Company seeks to reinforce those values within its workforce.

The Company is committed to pay equity and conducts a pay equity analysis on an annual basis. The Company's pay equity analysis for 20202021 indicated a zero percent (0%) pay gap between men and women.

Additionally, the Company offers a housing discount for associates that live at Company communities, and additionally offers retirement support, associate discount programs, and health benefit credits for participation in wellness programs. In 2021, the Company revised its wellness program to ensure associates had increased ability to rest and recharge including additional days off and resources to encourage physical, mental, and financial well-being. The Company engages in an annual compensation study to ensure that its compensation is aligned with market standards and that the Company is appropriately compensating its top performers. In 2019, the Company accomplished its goal of raising the minimum wage for all associates to $15 per hour.

In order to engage and promote communication with our associates and solicit meaningful feedback on our efforts to create a positive work environment, the Company has issuedissues engagement pulse surveys to all associates annually, and has begun transitioning to a shorter and more frequent pulse survey format in 2020.annually. The results of the 20202021 survey indicate that 93%94% of surveyed associates consider that their day-to-day work directly impacts the Company’s mission and vision, 91%94% believe that their opinions and ideas matter at Essex, and 93%94% feel that the Company supports diversity, equity and inclusion in the workplace.

The Company purchases general liability and property insurance coverage, including loss of rent, for each of its communities. The Company also purchases limited earthquake, terrorism, environmental and flood insurance. There are certain types of losses which may not be covered or could exceed coverage limits. The insurance programs are subject to deductibles and self-insured retentions in varying amounts. The Company utilizes a wholly owned insurance subsidiary, Pacific Western Insurance LLC ("PWI") to self-insure certain earthquake and property losses. As of December 31, 2020,2021, PWI had cash and marketable securities of approximately $152.8$198.1 million, and is consolidated in the Company's financial statements.

There are numerous housing alternatives that compete with the Company’s communities in attracting tenants. These include other apartment communities, condominiums and single-family homes. If the demand for the Company’s communities is reduced or if competitors develop and/or acquire competing housing, rental rates and occupancy may drop which may have a material adverse effect on the Company’s financial condition and results of operations.

The Company faces competition from other REITs, businesses and other entities in the acquisition, development and operation of apartment communities. Some competitors are larger and have greater financial resources than the Company. This competition may result in increased costs of apartment communities the Company acquires and/or develops.

The timing, source and amounts of cash flows provided by financing activities and used in investing activities are sensitive to changes in interest rates, stock price, and other fluctuations in the capital markets environment, which can affect the Company’s plans for acquisitions, dispositions, development and redevelopment activities.

The Company intends to continue to operate in a manner that will not subject it to regulation under the Investment Company Act of 1940. The Company may in the future (i) issue securities senior to its common stock, (ii) fund acquisition activities with borrowings under its line of credit and (iii) offer shares of common stock and/or units of limited partnership interest in the Operating Partnership or affiliated partnerships as partial consideration for property acquisitions. The Company from time to time acquires partnership interests in partnerships and joint ventures, either directly or indirectly through subsidiaries of the Company, when such entities’ underlying assets are real estate.

The Company invests primarily in apartment communities that are located in predominantly coastal markets within Southern California, Northern California, and the Seattle metropolitan area. The Company currently intends to continue to invest in apartment communities in such regions. However, these practices may be reviewed and modified periodically by management.

In addition, rentRent control or rent stabilization laws, and new such laws that may be implemented, and other regulatory restrictions may limit our ability to increase rents and pass through new or increased operating costs to our tenants. There has been a recent increase in municipalities, including those in which we own properties, considering or being urged by advocacy groups to consider rent control or rent stabilization laws and regulations or take other actions which could limit our ability to raise rents based solely on market conditions. These initiatives and any other future enactments of rent control or rent stabilization laws or other laws regulating multifamily housing, as well as any lawsuits against the Company arising from such rent control or other laws, may reduce rental revenues or increase operating costs. Such laws and regulations limit our ability to charge market rents, increase rents, evict tenants or recover increases in our operating expenses and could reduce the value of our communities or make it more difficult for us to dispose of properties in certain circumstances. Expenses associated with our investment in these communities, such as debt service, real estate taxes, insurance and maintenance costs, are generally not reduced when circumstances cause a reduction in rental income from the community. Furthermore, such regulations may negatively impact our ability to attract higher-paying tenants to such communities.

Our properties may also incur significant costs or losses related to legislative mandates including shelter-in-place orders, business shut-downs, quarantines, infection or other related factors, which may result in a negative impact on our occupancy levels. For example, many companies initially required, and now are continuing to allow or require, employees to “work from home” for an extended period of time, causing some tenants to move away from the urban centers temporarily or permanently. Some businesses have been ordered to temporarily shut down, such as indoor dining, and many have permanently closed due to deteriorating economic conditions, which has contributed to the shuttering of some commercial spaces in downtown areas, and the temporary, or possibly permanent, deterioration of neighborhoods in and around some of our urban communities, which may be further worsened by increases in homelessness and crime as a result of the effects of the pandemic on some individuals and communities. Moreover, we typically conduct aspects of our leasing activity on-site at our apartment communities. Reductions in the ability and willingness of prospective residents to visit our communities due to the COVID-19 pandemic could reduce rental revenue and ancillary operating revenue produced by our properties. Additionally, in connection with an outbreak that directly impacts one or more of our corporate offices or apartment communities, we may experience negative publicity and/or an unwillingness of prospective residents to visit or ultimately choose to live in our communities, which could directly affect our rental revenue. In addition, we have incurred costs associated with protecting our employees and residents, including the purchase of personal protective equipment and disinfecting our properties, and those costs may continue to increase.crime. There may also be an increased risk of material litigation due to the effects of the COVID-19 pandemic, including litigation brought by our residents or employees. To the extent our management or personnel are impacted in significant numbers by the COVID-19 pandemic and are not available or allowed to conduct work, our business and operating results may be negatively impacted. Additionally, our corporate offices remain closed as we have instituted “work from home” measures for our corporate associates, which may impact productivity and our employees’ overall mental health.

The Company may experience increased costs associated with capital improvements and routine property maintenance, such as repairs to the foundation, exterior walls, and rooftops of its properties, as its properties advance through their life-cycles. In some cases, we may spend more than budgeted amounts to make necessary improvements or maintenance. Increases in the

Joint venture partners often have shared control over the development and operation of the joint venture assets. Therefore, it is possible that a joint venture partner in an investment might become bankrupt, or have economic or business interests or goals that are inconsistent with the Company’s business interests or goals, or be in a position to take action contrary to the Company’s instructions or requests, or its policies or objectives. Consequently, a joint venture partner's actions might subject property owned by the joint venture to additional risk. Although the Company seeks to maintain sufficient influence over any joint venture to achieve its objectives, the Company may be unable to take action without its joint venture partners’ approval. A joint venture partner might fail to approve decisions that are in the Company’s best interests. Should a joint venture partner become bankrupt, the Company could become liable for such partner’s share of joint venture liabilities. In some instances, the Company and the joint venture partner may each have the right to trigger a buy-sell arrangement, which could cause the Company to sell its interest, or acquire a partner’s interest, at a time when the Company otherwise would not have initiated such a transaction.

The Company also owns properties indirectly under "DownREIT" structures. The Company has entered into, and in the future may enter into, transactions that could require the Company to pay the tax liabilities of partners that contribute assets into DownREITs, joint ventures or the Operating Partnership, in the event that certain taxable events, which are within the Company’s control, occur. Although the Company plans to hold the contributed assets or, if such assets consist of real property, defer recognition of gain on sale of such assets pursuant to the like-kind exchange rules under Section 1031 of the Internal Revenue Code of 1986, as amended (the "Code"), the Company can provide no assurance that the Company will be able to do so and if such tax liabilities were incurred they could have a material impact on its financial position.

Also, from time to time, the Company invests in properties which may be subject to certain shared facilities agreements with homeowners'homeowners’ associations and other entities and/or invests in properties subject to ground leases where a subtenant may have certain similar rights to that of a party under such a shared facilities agreement. For such properties,agreement and the Company'sCompany’s ability to control the expenditure of capital improvementsexpenditures, make necessary repairs and its allocation with such other partiescontrol certain decisions may adversely affect the Company's business, financial condition and results of operations.

These transactions or any other acquisitions involve risks and uncertainties. For example, as a consequence of such transactions, we may assume unknown liabilities, which could ultimately lead to material costs for us. In addition, the integration of acquired businesses or other acquisitions may not be successful and could result in disruption to other parts of our business. To integrate acquired businesses or other acquisitions, we must implement our management information systems, operating systems and internal controls, and assimilate and manage the personnel of the acquired operations. The expected synergies from acquisitions may not be fully realized, which could result in increased costs or other issues and have an adverse effect on our business. There can be no assurance that all pre-acquisition property due diligence will have identified all material issues that might arise with respect to such acquired business and its properties or as to any such other acquisitions. Any future acquisitions we make may also require significant additional debt or equity financing, which, in the case of debt financing, would increase our leverage and potentially affect our credit ratings and, in the case of equity or equity-linked financing, could be dilutive to Essex's stockholders and the Operating Partnership's unitholders. Additionally, the value of these investments could decline for a variety of reasons. These and other factors could affect our ability to achieve anticipated levels of profitability at acquired operations or realize other anticipated benefits of an acquisition, and could adversely affect our business, financial condition and results of operations.

Investments in real property create a potential for environmental liabilities on the part of the owner of such real property. The Company carries certain limited insurance coverage for this type of environmental risk as to its properties; however, such coverage is not fully available for all properties and, as to those properties for which limited coverage is fully available, it may not apply to certain claims arising from known conditions present on those properties. In general, in connection with the ownership (direct or indirect), operation, financing, management and development of its communities, the Company could be considered as the owner or operator of such properties or as having arranged for disposal or treatment of hazardous substances present there and therefore may be potentially liable for removal or clean-up costs, as well as certain other costs and environmental liabilities. The Company may also be subject to governmental fines, costs related to injuries to third parties and/or damage to a third party's property.

Properties which we plan to acquire undergo a pre-acquisition Phase I environmental site assessment, which is intended to afford the Company protection against so-called "owner liability" under the primary federal environmental law, as well as further environmental assessment, which may involve invasive techniques such as soil or ground water sampling where conditions warranting such further assessment are identified and seller’s consent is obtained. Despite these assessments, no assurance can be given that all environmental conditions present on or beneath or emanating from a given property will be discovered or that the full nature and extent of those conditions which are discovered will be adequately ascertained and quantified.

In connection with our ownership, operation and development of communities, from time to time we undertake remedial action in response to the presence of subsurface or other contaminants, including contaminants in soil, groundwater and soil vapor beneath or affecting our buildings. The Company does so pursuant to appropriate environmental regulatory requirements with the objective of obtaining regulatory closure or a no further action determination that will allow for future use, development and sale of any impacted community.

Mold growth may occur when excessive moisture accumulates in buildings or on building materials, particularly if the moisture problem remains undiscovered or is not addressed in a timely manner. Although the occurrence of mold at multifamily and other structures, and the need to remediate such mold, is not a new phenomenon, there has been increased awareness in recent

years that certain molds may in some instances lead to adverse health effects, including allergic or other reactions. The Company has adopted policies for promptly addressing and resolving reports of mold when it is detected, and to minimize any impact mold might have on tenants of the affected property. The Company believes its mold policies and proactive response to address any known mold existence reduce its risk of loss from these cases;property, however, no assurance can be provided that the Company has identified and responded to all mold occurrences.

All of our communities are located in areas that are subject to earthquake activity. The Company evaluates its financial loss exposure to seismic events by using actuarial loss models developed by the insurance industry and property vulnerability analyses based on structural evaluations by seismic consultants. The Company manages this exposure, where considered appropriate, desirable, and cost-effective, by upgrading properties to increase their resistance to forces caused by seismic events, by considering available funds and coverages provided by PWI and/or, in some cases, by purchasing seismic insurance. Purchasing seismic insurance coverage can be costly and such seismic insurance is in limited supply. As a result, the Company may experience a shortage in desired coverage levels if market conditions are such that insurance is not available, or the cost of the insurance makes it, in management's view, not economically practical. The Company may purchase limited earthquake insurance for certain high-density properties and, in most cases, properties owned by the Company's co-investments.

The Company carries other types of insurance coverage related to a variety of risks and exposures, including cyber risk insurance. There has been a reduction in the number of insurance companies in the market offering certain types of insurance the Company has previously purchased and premiums have materially increased for certain types of insurance coverage. Based on market conditions, the Company may change or potentially eliminate insurance coverages, or increase levels of self-insurance. Further, we cannot assure you that the Company will not incur losses, which could be material, due to uninsured risks, deductibles and self-insured retentions, and/or losses in excess of coverage limits.

We have significant investments in large metropolitan markets, such as the metropolitan markets in Southern California, Northern California, and Seattle. These markets may in the future be the target of actual or threatened terrorist attacks. Future terrorist attacks in these markets could directly or indirectly damage our communities, both physically and financially, or cause losses that exceed our insurance coverage. Our communities could also directly or indirectly be the location or target of actual or threatened terrorist attacks, crimes, shootings, other acts of violence or other incidents beyond our control, the occurrence of which could directly impact the value of our communities through damage, destruction, loss or increased security costs, as well as operational losses due to reduction of traffic and rental demand for our communities, and the availability of insurance for such acts may be limited or may be subject to substantial costs. If such an incident were to occur at one of our communities, we

may also be subject to significant liability claims. Such events and losses could significantly affect our ability to operate those communities and materially impair our ability to achieve our expected results. Additionally, we may be obligated to continue to pay any mortgage indebtedness and other obligations relating to affected properties.

Although the Company may carry insurance for potential losses associated with its communities, employees, tenants, and compliance with applicable laws, it may still incur losses due to uninsured risks, deductibles, copayments or losses in excess of applicable insurance coverage and those losses may be material. In the event of a substantial loss, insurance coverage may not be able to cover the full replacement cost of the Company’s lost investment, or the insurance carrier may become insolvent and not be able to cover the full amount of the insured losses. Changes in building codes and ordinances, environmental considerations and other factors might also affect the Company’s ability to replace or renovate an apartment community after it has been damaged or destroyed. In addition, certain causalities and/or losses incurred may expose the Company in the future to higher insurance premiums.

Public utilities, especially those that provide water and electric power, are fundamental for the consistent operation of our communities. The delayed delivery or any material reduction or prolonged interruption of these services may cause tenants to terminate their leases or may result in a reduction of rents and/or increase in our costs or other issues.In addition, we may fail to provide quality housing and continuous access to amenities as a result of other factors, including government mandated closures, due to health concerns, mechanical failure, power outage, human error, vandalism, physical or electronic security breaches, war, terrorism or similar events.Additionally, residents may choose not to use such facilities or amenities as a matter of social distancing or for other reasons, which may cause our communities to become less appealing to such residents. Such service interruptions, closures or lack of use of facilities, mechanical failures or other events may also expose us to additional liability claims and damage our reputation and brand and could cause tenants to terminate or not renew their leases, or prospective tenants to seek housing elsewhere. Any such failures could impair our ability to continue providing quality housing and consistent operation of our communities, which could adversely affect our business, financial condition and results of operations.

We face risks associated with land holdings and related activities. We hold land for future development and may in the future acquire additional land holdings. The risks inherent in purchasing, owning and developing land increase as demand for apartments, or rental rates, decrease. Real estate markets are highly uncertain and, as a result, the value of undeveloped land may fluctuate significantly. In addition, carrying costs can be significant and can result in losses or reduced profitability. As a result, we hold certain land, and may, in the future acquire additional land, in our development pipeline at a cost we may not be able to fully recover or at a cost which may preclude our developing a profitable multifamily community. If there are subsequent changes in the fair value of our land holdings which we determine is less that the carrying basis of our land holdings reflected in our financial statements plus estimated costs to sell, we may be required to take future impairment changes which could have a material adverse effect on our results of operations.

Although we have taken steps to abide by privacy and security laws, and to protect the security of our information systems and maintain confidential tenant, prospective tenant and employee information, the compliance and security measures put in place by the Company, and such vendors, cannot guarantee perfect compliance or provide absolute security, and the Company and our vendors' compliance systems and/or information technology infrastructure may be vulnerable to criminal cyber-attacks or data security incidents, including, ransom of data, such as, without limitation, tenant and/or employee information, due to employee error, malfeasance, or other vulnerabilities. Any such incident could compromise the Company’s or such vendors'vendors’ networks (or the networks or systems of third parties that facilitate the Company’s or such vendors’ business activities), and the information stored by the Company or such vendors could be accessed, misused, publicly disclosed, corrupted, lost, or stolen, resulting in fraud, including wire fraud related to Company assets, or other harm. Moreover, if there is a compliance failure, or if a data security incident or breach affects the Company’s systems or such vendors'vendors’ systems, whether through a breach of the Company’s systems or a breach of the systems of third parties, or results in the unauthorized release of personally identifiable information, the Company’s reputation and brand could be materially damaged, which could increase our costs in attracting and retaining tenants, and other serious consequences may result. Such potential other consequences include, without limitation, that the Company and certain executive officers may be exposed to a risk of litigation, and possible liability, including, without limitation, government enforcement actions, and private litigation;

Privacy and information security risks have generally increased in recent years because of the proliferation of new technologies, such as ransomware, and the increased sophistication and activities of perpetrators of cyber-attacks. In light of the increased risks, we have dedicated additional Company resources to strengthening the security of the Company’s computer systems, including maintainingWe maintain cyber risk insurance which may provide some coverage for certain risks arising out of cyber breaches. However, there can be no assurance that our cyber risk insurance will be sufficient in the event of a cyber incident.

In the future, the Company may expend additional resources to continue to enhance the Company’s information security measures to investigate and remediate any information security vulnerabilities and/or to further ensure compliance with privacy and information security laws. Despite these steps, there can be no assurance that the Company will not suffer a significant data security incident in the future, that unauthorized parties will not gain access to sensitive data stored on the Company’s systems, or that any such incident will be discovered in a timely manner. Any failure in or breach of the Company'sCompany’s information security systems, those of third party service providers, or a breach of other third party systems that ultimately impacts the operational or information security systems of the Company as a result of cyber-attacks or information security breaches could result in a wide range of potentially serious harm to our business and results of operations. Additionally, government agencies involved in investigating any potential data security incidents may impose injunctive relief or other civil or criminal penalties on the Company and/or certain executives, which could, among other things, divert the attention of management, impact the Company's ability to collect and use tenant information, materially increase data security costs and/or otherwise require us to alter how we operate our business. Further, the techniques used by criminals to obtain unauthorized access to sensitive data, such as phishing and other forms of human engineering, are increasing in sophistication and are often novel or change frequently; accordingly, the Company may be unable to anticipate these techniques or implement adequate preventative measures.

Our properties may also incur significant costs or losses related to legislative mandates which may result in a negative impact on our occupancy levels. For example, many companies initially required, and now are continuing to allow or require, employees to “work from home” for an extended period of time, causing some tenants to move away from the urban centers temporarily or permanently. Some businesses many have permanently closed due to deteriorating economic conditions, which has contributed to the temporary, or possibly permanent, deterioration of neighborhoods in and around some of our urban communities, obtain new financing,which may be further worsened by increases in homelessness and refinance existing borrowing at competitive rates couldcrime. There may also be adversely affected, which would impactan increased risk of material litigation due to the Company's financial standing and related credit rating. In addition, ifeffects of the COVID-19 pandemic, including litigation brought by our residents or employees.

From time to time, the Company, through the Operating Partnership, makes certain co-investments in the form of preferred equity investments in third-party entities that have been formed for the purpose of acquiring, developing, financing, throughor managing real property. With preferred equity investments and certain other sourcesco-investments, the Operating Partnership’s interest in a particular entity is typically less than a majority of the outstanding voting interests of that entity. Therefore, the Operating Partnership’s ability to control the daily operations of such co-investment may be limited. The Operating Partnership may not be able to dispose of its interests in such co-investment. In the event that such co-investment or the partners in such co-investment become insolvent or bankrupt or fail to develop or operate the property in the manner anticipated and expected, the Operating Partnership may not receive the expected return in its expected timeframe or at all and may lose up to its entire investment in, and any advances to, the co-investment. Additionally, the preferred return negotiated on these co-investments may be lower than the Company's cost of funds. The Company may also incur losses if any guarantees or indemnifications were made by the Company.

These transactions or any other acquisitions involve risks and uncertainties. In addition, the integration of acquired businesses or other acquisitions may not be successful and could result in disruption to other parts of our liquidity,business. To integrate acquired businesses or other acquisitions, we must implement our management information systems, operating systems and internal controls, and assimilate and manage the personnel of the acquired operations. There can be no assurance that all pre-acquisition property due diligence will have identified all material issues that might arise with respect to such acquired business and its properties or as to any such other acquisitions. Any future acquisitions we make may also require significant additional debt or equity financing, which, in the case of secured financings,debt financing, would increase our leverage and potentially affect our credit ratings and, in the case of equity or equity-linked financing, could resultbe dilutive to Essex's stockholders and the Operating Partnership's unitholders. Additionally, the value of these investments could decline for a variety of reasons. These and other factors could affect our ability to achieve anticipated levels of profitability at acquired operations or realize other anticipated benefits of an acquisition, and could adversely affect our business, financial condition and results of operations.
