DOCUMENTS INCORPORATED BY REFERENCE:

This report combines the annual reports on Form 10-K for the year ended December 31, 20182021 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, 2018,2021, 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 Unit holders.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 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

Acquisitions are an important component of the Company’s business plan, and during 2018,plan. The tables below summarize acquisition activity for the Company acquired ownership interests in two communities comprised of 384 apartment homes for $139.4 million. 

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. Generally,In general, the Company seeks to have anyoffset the dilutive impact ofon long-term earnings dilution resultingand funds from operations from these dispositions offset bythrough the positive impact of its acquisitions, development and redevelopment activities.reinvestment of proceeds.

In June 2018,For the year ended December 31, 2021, the Company sold Domain,four communities consisting of 912 apartment homes for 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, 2018,2021, the Company's development pipeline was comprised of fourone consolidated projectsproject under development and twoone unconsolidated joint venture projectsproject under development aggregating 1,861371 apartment homes, with total incurred costs of $812.0$156.0 million, and estimated remaining project costs of approximately $417.0$61.0 million, $310.0$32.6 million of which represents the Company's share of estimated remaining costs, for total estimated project costs of $1.2 billion.$217.0 million.

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, 2018,2021, 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):

During 2018,2021, the Company made regularly scheduled principal payments and loan payoffs of $297.5$3.5 million ofto its secured mortgage notes payable at an average interest rate of 5.1%2.9%.

The Company's $1.2 billion credit facility had an interest rate of LIBOR plus 0.875%0.775%, with a scheduled maturity date in December 2021September 2025 with one 18-month extension,three 6-month extensions, exercisable at the Company's option. In January 2019, the line of credit facility was amended such that the scheduled maturity date was extended to December 2022 with one 18-month extension, exercisable at the Company's option. The interest rate on the amended line is based on a tiered rate structure tied to the Company's corporate ratings and is currently at LIBOR plus 0.825%. The Company's $35.0 million working capital unsecured line of credit had an interest rate of LIBOR plus 0.875%0.775%, with a scheduled maturity date in January 2020.February 2023.

In September 2018,2021, the Company entered into a new equity distribution agreement pursuant to which the Company may offer and sell shares of its common stock having an aggregate gross sales price of up to $900.0 million (the "2018“2021 ATM Program"Program”). In connection with the 20182021 ATM Program, the Company may also enter into related forward sale agreements, whereby, at the Company’s discretion, itand may sell shares of its common stock under the 2018 ATM Program under forward salespursuant to these agreements. The use of a forward salessale agreement would allow the Company to lock in a share price on the sale of shares of its common stock at the time the agreement is executed, but defer receivingreceipt of the proceeds from the sale of shares until a later date.date should the Company elect to settle such forward sale agreement, in whole or in part, in shares of its common stock.

Upon entering into the 2018The 2021 ATM Program replaces the Company simultaneously terminated its existingCompany’s prior equity distribution agreements, which wereagreement entered into in March 2016 in connection with its prior at-the-market equity offering programSeptember 2018 (the "2016“2018 ATM Program"Program”)., which was terminated upon the establishment of the 2021 ATM Program. During the year ended December 31, 2018,2021, the Company did not sellissue any shares of its common stock through the 20182021 ATM Program or through the 20162018 ATM Program. Since commencement of the 2018 ATM Program, asAs of December 31, 2018, the Company has not sold any shares of its common stock and2021, there arewere no outstanding forward sale agreements, and $900.0 million of shares remainsremain available to be sold under the 20182021 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, 2018,2021, the Company had 1,8261,757 employees, ninety-nine percent (99%) of which were full-time employees, and of which 1,382 employees worked in operations and 375 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 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, 2018,2021, PWI had cash and marketable securities of approximately $86.6$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 Company believes that cash flows generated by its operations, existing cash and cash equivalents, marketable securities balances, availability under existing lines of credit, access to capital markets and the ability to generate cash from the disposition of real estate are sufficient to meet all of its reasonably anticipated cash needs during 2019.2022.

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.

Rent 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.

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 Company’s expenses to own and maintain its properties could adversely impact the Company’s financial condition and results of operations.

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 have not have initiated such a transaction.

From time to time, the Company, through the Operating Partnership, investsmakes certain co-investments in corporations, limited partnerships, limited liability companies or otherthe form of preferred equity investments in third-party entities that have been formed for the purpose of acquiring, developing, financing, or managing real property. For example, the Company has made co-investments in the form of preferred equity investments in third party entities that own real estate and may continue in the future to make such preferred equity or other co-investments. With preferred equity investments and certain other co-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. Furthermore, the Operating Partnership may not have the power to remove a majority of the board of directors (in the case of a corporation) or the general partner or partners (in the case of a limited partnership) of such co-investment in the event that its operations conflict with the Operating Partnership’s objectives. The Operating Partnership may not be able to dispose of its interests in such co-investment. In the event that such co-investment becomesor the partners in such co-investment become insolvent or failsbankrupt 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.

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 whichthat 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 existing 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 harmaffect 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, and costs related to injuries to third persons andparties and/or damage to theira third party's property.

Properties which we intendplan 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. While suchDespite these assessments, are conducted in accordance with applicable "all appropriate inquiry" standards, 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.

Certain environmental laws impose liability for release of asbestos-containing materials ("ACMs") into the air or exposure to lead-based paint ("LBP"), and third parties may seek recovery from owners or operators of apartment communities for personal injury associated with ACMs or LBP.

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 property. The Company believes its mold policies and proactive response to address any known mold existence reduce its risk of loss from these cases;affected property, however, no assurance can be provided that the Company has identified and responded to all mold occurrences.

All theof 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 in most cases property vulnerability analysisanalyses based on structural evaluations ofby 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, assetsproperties owned by the Company's co-investments.

The Company carries other types of insurance coverage related to a variety of risks and exposures.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.

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.

Mr. Marcus has agreed not to divulge any confidential or proprietary information that may be received by him in his capacity as Chairman of the Company to any of his affiliated companies and that he will absent himself from any and all discussions by Essex's Board of Directors regarding any proposed acquisition and/or development of an apartment community where it appears that there may be a conflict of interest with any of his affiliated companies. Notwithstanding this agreement, Mr. Marcus and his affiliated entities may potentially compete with the Company in acquiring and/or developing apartment communities, which competition may be detrimental to the Company. In addition, due to such potential competition for real estate investments, Mr. Marcus and his affiliated entities may have a conflict of interest with the Company, which may be detrimental to the interests of the Essex's stockholders and the Operating Partnership's unitholders.

The statute permits various exemptions from its provisions, including business combinations that are exempted by the board of directors prior to the time that the interested stockholder becomes an interested stockholder. These voting provisions do not apply if the stockholders receive a minimum price, as defined under the Maryland General Corporation Law. As permitted by the statute, the Board of Directors of Essex irrevocably has elected to exempt any business combination among the Company, George M. Marcus, who is the chairman of the Company, and MMC or any entity owned or controlled by Mr. Marcus and MMC. Consequently, the five-year prohibition and supermajority vote requirements described above will not apply to any business combination between the Company, Mr. Marcus, or MMC. As a result, the Company may in the future enter into business combinations with Mr. Marcus and MMC, without compliance with the supermajority vote requirements and other provisions of the Maryland Business Combination Act.

The Company’s Charter authorizes the issuance of additional shares of common stock or preferred stock and the setting of the preferences, rights and other terms of such stock without the approval of the holders of the common stock. The Company may establish one or more classes or series of stock that could delay, defer or prevent a transaction or a change in control. Such a transaction might involve a premium price for the Company’s stock or otherwise be in the best interests of the holders of

The Company’s Charter contains provisions limiting the transferability and ownership of shares of capital stock, which may delay, defer or prevent a transaction or a change in control. For example, subject to receiving an exemption from the Board of Directors, potential acquirers may not purchase more than 6% in value of the stock (other than qualified pension trusts which can acquire 9.9%). This may discourage tender offers that may be attractive to the holders of common stock and limit the opportunity for stockholders to receive a premium for their shares of common stock.

The Maryland General Corporation Law restricts the voting rights of holders of shares deemed to be "control shares." Under the Maryland General Corporation Law, "control shares" are those which, when aggregated with any other shares held by the acquirer, entitle the acquirer to exercise voting power within specified ranges. Although the Bylaws exempt the Company from the control share provisions of the Maryland General Corporation Law, the Board of Directors may amend or eliminate the provisions of the Bylaws at any time in the future. Moreover, any such amendment or elimination of such provision of the Bylaws may result in the application of the control share provisions of the Maryland General Corporation Law not only to control shares which may be acquired in the future, but also to control shares previously acquired. If the provisions of the Bylaws are amended or eliminated, the control share provisions of the Maryland General Corporation Law could delay, defer or

prevent a transaction or change in control that might involve a premium price for the stock or otherwise be in the best interests of the Company’s stockholders.

The Company’s Charter and Bylaws as well as Maryland General Corporation Law also contain other provisions that may impede various actions by stockholders without approval of Essex’s Board of Directors, and that in turn may delay, defer or prevent a transaction, including a change in control that might involve a premium price for the stock or otherwise be in the best interests of the Company'sCompany’s stockholders. Those provisions include, among others:

The Company’s portfolio as of December 31, 20182021 (including communities owned by unconsolidated joint ventures, but excluding communities underlying preferred equity investments) was comprised of 245252 stabilized operating apartment communities (comprising 59,66161,911 apartment homes), of which 26,69526,245 apartment homes are located in Southern California, 21,14623,141 apartment homes are located in Northern California, and 11,82012,525 apartment homes are located in the Seattle metropolitan area. The Company’s apartment communities accounted for 99.3% of the Company’s revenues for the year ended December 31, 2018.2021.

Financial occupancy is defined as the percentage resulting from dividing actual rental revenueincome by total potentialscheduled rental revenue.income. Total potentialscheduled rental revenueincome represents the value of all apartment homes, with occupied apartment homes valued at contractual rental rates pursuant to leases and vacant apartment homes valued at estimated market rents. When calculating actual rents for occupied apartment homes and market rents for vacant apartment homes, delinquencies and concessions are not taken into account. The Company believes that financial occupancy is a meaningful measure of occupancy because it considers the value of each vacant unit at its estimated market rate. Financial occupancy may not completely reflect short-term trends in physical occupancy and financial occupancy rates, and the Company's calculation of financial occupancy may not be comparable to financial occupancy as disclosed by other REITs. Market rates are determined using the recently signed effective rates on new leases at the property and are used as the starting point in the determination of the market rates of vacant apartment homes. The Company may increase or decrease these rates based on a variety of factors, including overall supply and demand for housing, concentration of new apartment deliveries within the same submarket which can cause periodic disruption due to greater rental concessions to increase leasing velocity, and rental affordability.

For communities that are development properties in lease-up without stabilized occupancy figures, the Company believes the physical occupancy rate is the appropriate performance metric. While a community is in the lease-up phase, the Company’s primary motivation is to stabilize the property, which may entail the use of rent concessions and other incentives, and thus financial occupancy which is based on contractual revenueincome is not considered the best metric to quantify occupancy.

The Company’s communities are primarily urban and suburban high density wood frame communities comprising of three to seven stories above grade construction with structured parking situated on 1-10 acres of land with densities averaging between 30-80+ units per acre. As of December 31, 2018,2021, the Company’s communities include 103104 garden-style, 129138 mid-rise, and 1310 high-rise communities. Garden-style communities are generally defined as on-grade properties with two and/or three-story buildings with no structured parking while mid-rise communities are generally defined as properties with three to seven story buildings and some structured parking. High-rise communities are typically defined as properties with buildings that are greater than seven stories, are steel or concrete framed, and frequently have structured parking. The communities have an average of approximately 244246 apartment homes, with a mix of studio, one-, two- and some three-bedroom apartment homes. A wide variety of amenities are available at the Company’s communities, including covered parking, fireplaces, swimming pools, clubhouses with fitness facilities, volleyball and playground areas and tennis courts.dog parks.
