EXPLANATORY NOTE

This report combines the reports on Form 10-Q for the three and six month periods ended June 30, 2018 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” 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 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 offering. 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-Q of Essex and the Operating Partnership into this single report provides the following benefits:

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

• eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the disclosure applies to both Essex and the Operating Partnership; and

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

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 joint ventures. 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 joint ventures.

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 condensed 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 condensed consolidated financial statements and as noncontrolling interest in Essex’s condensed consolidated financial statements. The noncontrolling interest in the Operating Partnership's consolidated financial statements include the interest of unaffiliated partners in various condensed consolidated partnerships and joint venture partners. The noncontrolling interest in Essex's consolidated financial statements include (i) the same noncontrolling interest as presented in

iii

the Operating Partnership’s consolidated financial statements and (ii) OP Unit holders. 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-Q 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-Q also includes separate Part I, Item 4. 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-Q 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 joint ventures 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 unaudited condensed consolidated balance sheets, statements of income and 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 condensed consolidated financial statements for the interim periods and are normal and recurring in nature, except as otherwise noted.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the notes to such unaudited condensed consolidated financial statements and Management's Discussion and Analysis of Financial Condition and Results of Operations herein. Additionally, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2017.

Notes to Condensed Consolidated Financial Statements

June 30, 2018 and 2017

(Unaudited)

(1) Organization and Basis of Presentation

The accompanying unaudited condensed consolidated financial statements present the accounts of Essex Property Trust, Inc. (“Essex” or the “Company”), which include the accounts of the Company and Essex Portfolio, L.P. and its subsidiaries (the “Operating Partnership,” which holds the operating assets of the Company), prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q. In the opinion of management, all adjustments necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented have been included and are normal and recurring in nature. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2017.

All significant intercompany accounts and transactions have been eliminated in the unaudited condensed consolidated financial statements. Certain reclassifications have been made to conform to the current year’s presentation, including the reclassification of corporate-level property management expenses out of property operating, excluding real estate taxes to its own line item on the Company's condensed consolidated statements of income and comprehensive income. Additionally, $10.0 million and $9.3 million has been reclassified out of other assets and into building and improvements on the Company's condensed consolidated balance sheets as of June 30, 2018 and December 31, 2017, respectively.

The unaudited condensed consolidated financial statements for the three and six months ended June 30, 2018 and 2017 include the accounts of the Company and the Operating Partnership. Essex is the sole general partner of the Operating Partnership, with a 96.7% general partnership interest as of both June 30, 2018 and December 31, 2017. Total Operating Partnership limited partnership units (“OP Units,” and the holders of such OP Units, “Unitholders”) outstanding were 2,272,983 and 2,268,114 as of June 30, 2018 and December 31, 2017, respectively, and the redemption value of the units, based on the closing price of the Company’s common stock totaled approximately $543.4 million and $547.5 million as of June 30, 2018 and December 31, 2017, respectively.

As of June 30, 2018, the Company owned or had ownership interests in 247 operating apartment communities, comprising 59,982 apartment homes, excluding the Company’s ownership in preferred equity interest co-investments, one operating commercial building, six active developments and three loan investments. The operating apartment communities are located in Southern California (Los Angeles, Orange, San Diego, and Ventura counties), Northern California (the San Francisco Bay Area) and the Seattle metropolitan areas.

Accounting Pronouncements Adopted in the Current Year

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09 “Revenue from Contracts with Customers.” The new standard provides a single comprehensive revenue recognition model for contracts with customers (excluding certain contracts, such as lease contracts) to improve comparability within industries. The new standard requires an entity to recognize revenue to reflect the transfer of goods or services to customers at an amount the entity expects to be paid in exchange for those goods and services and provide enhanced disclosures, all to provide more comprehensive guidance for transactions such as service revenue and contract modifications. The new standard is effective for interim and annual periods beginning after December 15, 2017. The new standard may be applied using either a full retrospective or a modified approach upon adoption. The Company adopted ASU No. 2014-09 as of January 1, 2018 using the modified retrospective approach. See Note 3, Revenues, for further details.

In January 2016, the FASB issued ASU No. 2016-01 “Recognition and Measurement of Financial Assets and Financial Liabilities,” which requires changes to the classification and measurement of investments in certain equity securities and to the presentation of certain fair value changes for financial liabilities measured at fair value. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2016-01 as of January 1, 2018 using the modified retrospective method by applying a cumulative effect adjustment to retained earnings and partners' capital of $2.2 million, representing accumulated net unrealized gains of certain equity securities held by the Company. Furthermore, as a result of the adoption of this standard, the Company will recognize changes in the fair value of equity investments with readily determinable fair values through net income as opposed to comprehensive income.

(Unaudited)

In August 2016, the FASB issued ASU No. 2016-15 “Classification of Certain Cash Receipts and Cash Payments,” which requires entities to adhere to a uniform classification and presentation of certain cash receipts and cash payments in the statement of cash flows. The amendments in this update provide guidance on eight specific cash flow issues. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2016-15 as of January 1, 2018 using the retrospective transition method. This amendment did not have a material impact on the Company's consolidated results of operations or financial position.

In November 2016, the FASB issued ASU No. 2016-18 “Statement of Cash Flows,” which requires entities to include restricted cash and restricted cash equivalents in the reconciliation of beginning-of-period to the end-of-period of cash and cash equivalents in the statement of cash flows. This new standard seeks to eliminate the current diversity in practice in how changes in restricted cash and restricted cash equivalents is presented in the statement of cash flows. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2016-18 as of January 1, 2018 using the retrospective transition method. This amendment did not have a material impact on the Company's consolidated results of operations or financial position.

In January 2017, the FASB issued ASU No. 2017-01 “Business Combinations: Clarifying the Definition of a Business,” which provides a new framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Previously, U.S. GAAP did not specify the minimum inputs and processes required for an integrated set of assets and activities to meet the definition of a business, causing a broad interpretation of the definition of a business. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2017-01 as of January 1, 2018 prospectively. The Company expects that substantially all of its acquisitions of communities will qualify as asset acquisitions and transaction costs related to these acquisitions will be capitalized upon adoption.

In February 2017, the FASB issued ASU No. 2017-05 “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets,” which adds guidance for partial sales of nonfinancial assets, including partial sales of real estate. Historically, U.S. GAAP contained several different accounting models to evaluate whether the transfer of certain assets qualified for sale treatment. This new standard reduces the number of potential accounting models that might apply and clarifies which model does apply in various circumstances. Partial sales of nonfinancial assets are common in the real estate industry and include transactions in which the seller retains an equity interest in the entity that owns the assets or has an equity interest in the buyer. The new standard is effective for interim and annual periods beginning after December 15, 2017. Management performed an evaluation of all of the Company's contracts that may be affected by the new standard. The Company adopted ASU No. 2017-05 concurrently with the adoption of ASU No. 2014-09 “Revenue from Contracts with Customers” as of January 1, 2018 using the modified-retrospective method by applying a cumulative effect adjustment to retained earnings and partners' capital of $123.7 million, representing the partial sale of its membership interest in BEX II, LLC (“BEX II”) during the fourth quarter of 2016.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02 “Leases,” which requires an entity that is a lessee to classify leases as either finance or operating and to recognize a lease liability and a right-of-use asset for all leases that have a duration of greater than 12 months. Leases of 12 months or less will be accounted for similar to existing guidance for operating leases today. For lessors, accounting for leases under the new standard will be substantially the same as existing guidance for sales-type leases, direct financing leases, and operating leases, but eliminates current real estate specific provisions and changes the treatment of initial direct costs. The new standard will be effective for the Company beginning on January 1, 2019 and early adoption is permitted, including adoption in an interim period. The Company currently anticipates adopting the new standard on the effective date. The Company expects that its residential and commercial leases, where it is the lessor, will continue to be accounted for as operating leases under the new standard. As a result, the Company does not currently expect significant changes in the accounting for its lease revenues. For leases where the Company is the lessee, which includes various corporate office and ground leases, the Company will be required to recognize a right of use asset and related lease liability on its consolidated balance sheets upon adoption. The Company expects that its corporate office leases, where it is the lessee, will continue to be accounted for as operating leases. The Company also expects to elect a package of practical expedients, under which the Company would not be required to reassess the classification of existing ground leases. The Company is continuing to evaluate the impact of this amendment on its consolidated results of operations and financial position.

In June 2016, the FASB issued ASU No. 2016-13 “Measurement of Credit Losses on Financial Instruments,” which amends the current approach to estimate credit losses on certain financial assets, including trade and other receivables, available-for-sale securities, and other financial instruments. Generally, this amendment requires entities to establish a valuation allowance for the expected lifetime losses of these certain financial assets. Subsequent changes in the valuation allowance are recorded in current earnings and reversal of previous losses are permitted. Currently, U.S. GAAP requires entities to write down credit losses only when losses are probable and loss reversals are not permitted. The new standard will be effective for the Company beginning on January 1, 2020 and early adoption is permitted. The Company is currently evaluating the impact of this amendment on its consolidated results of operations and financial position.

In August 2017, the FASB issued ASU No. 2017-12 “Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities,” which, among other things, requires entities to present the earnings effect of hedging instruments in the same income statement line item in which the earnings effect of the hedged item is reported. The new standard also adds new disclosure requirements. This new standard will be effective for the Company beginning January 1, 2019 and early adoption is permitted. The Company is currently evaluating the impact of this amendment on its consolidated results of operations and financial position.

Marketable Securities

The Company reports its equity securities and available for sale debt securities at fair value, based on quoted market prices (Level 1 for the common stock and investment funds, Level 2 for the unsecured bonds and Level 3 for investments in mortgage backed securities, as defined by the FASB standard for fair value measurements). Any unrealized gain or loss in debt securities classified as available for sale is recorded as other comprehensive income. Unrealized gains and losses in equity securities, realized gains and losses in debt securities, interest income, and amortization of purchase discounts are included in interest and other income on the condensed consolidated statements of income and comprehensive income.

As of June 30, 2018 and December 31, 2017, equity securities and available for sale debt securities consisted primarily of investment-grade unsecured bonds, common stock and stock funds, investments in mortgage backed securities, and investment funds that invest in U.S. treasury or agency securities. As of June 30, 2018 and December 31, 2017, the Company classified its investments in mortgage backed securities, which mature in November 2019 and September 2020, as held to maturity, and accordingly, these securities are stated at their amortized cost. The discount on the mortgage backed securities is being amortized to interest income based on an estimated yield and the maturity date of the securities.

As of June 30, 2018 and December 31, 2017, marketable securities consist of the following ($ in thousands):

The Company uses the specific identification method to determine the cost basis of a debt security sold and to reclassify amounts from accumulated other comprehensive income for such securities. 

For the three months ended June 30, 2018 and 2017, the proceeds from sales and maturities of marketable securities totaled $9.4 million and $3.9 million, respectively, which resulted in $0.2 million in realized loss and $13,000 in realized gains, respectively, for such periods. For the six months ended June 30, 2018 and 2017, the proceeds from sales and maturities of marketable securities totaled $19.0 million and $28.8 million, respectively, which resulted in $0.5 million and $1.6 million in realized gains, respectively, for such periods.

For the three and six months ended June 30, 2018, the portion of equity security unrealized gains and losses that were recognized in income totaled $0.1 million in unrecognized gains and $0.8 million in unrealized losses and is included in interest and other income on the Company's condensed consolidated statements of income and comprehensive income.

Variable Interest Entities

In accordance with accounting standards for consolidation of variable interest entities (“VIEs”), the Company consolidates the Operating Partnership, 16 limited partnerships, comprising eight communities, (the “DownREIT limited partnerships,”) and eight co-investments as of June 30, 2018. The Company consolidates these entities because it is deemed the primary beneficiary. The Company has no assets or liabilities other than its investment in the Operating Partnership. The consolidated total assets and liabilities related to the eight consolidated co-investments and 16 DownREIT limited partnerships, net of intercompany eliminations, were approximately $835.2 million and $262.9 million, respectively, as of June 30, 2018 and $837.7 million and $265.5 million, respectively, as of December 31, 2017. Noncontrolling interests in these entities were $64.9 million and $66.7 million as of June 30, 2018 and December 31, 2017, respectively. The Company's financial risk in each VIE is limited to its equity investment in the VIE. As of June 30, 2018 and December 31, 2017, the Company did not have any other VIEs of which it was deemed to be the primary beneficiary and did not have any VIEs of which it was not deemed to be the primary beneficiary.

Equity-based Compensation

The cost of share- and unit-based compensation awards is measured at the grant date based on the estimated fair value of the awards. The estimated fair value of stock options and restricted stock granted by the Company are being amortized over the vesting period. The estimated grant date fair values of the long term incentive plan units (discussed in Note 12, “Equity Based Compensation Plans,” in the Company’s annual report on Form 10-K for the year ended December 31, 2017) are being amortized over the expected service periods.

Fair Value of Financial Instruments

Management believes that the carrying amounts of the outstanding balances under its lines of credit, and notes and other receivables approximate fair value as of June 30, 2018 and December 31, 2017, because interest rates, yields, and other terms for these instruments are consistent with yields and other terms currently available for similar instruments. Management has estimated that the fair value of the Company’s fixed rate debt with a carrying value of $5.1 billion and $4.9 billion, including premiums, discounts and debt financing costs, at June 30, 2018 and December 31, 2017, respectively, was approximately $5.1 billion and $5.0 billion. Management has estimated that the fair value of the Company’s $615.1 million and $792.9 million of variable rate debt, net of debt financing costs, at June 30, 2018 and December 31, 2017, respectively, was approximately $618.2 million and $793.9 million based on the terms of existing mortgage notes payable, unsecured debt, and variable rate demand notes compared to those available in the marketplace. Management believes that the carrying amounts of cash and cash equivalents, restricted cash, accounts payable and accrued liabilities, construction payables, other liabilities, and dividends payable approximate fair value as of June 30, 2018 and December 31, 2017 due to the short-term maturity of these instruments. Marketable securities, except mortgage backed securities, and derivatives are carried at fair value as of June 30, 2018 and December 31, 2017.

At June 30, 2018, the Company’s investments in mortgage backed securities had a carrying value of $118.0 million and the Company estimated the fair value to be approximately $127.2 million. At December 31, 2017, the Company’s investments in mortgage backed securities had a carrying value of $109.5 million and the Company estimated the fair value to be approximately $120.7 million. The Company determines the fair value of the mortgage backed securities based on unobservable inputs (level 3 of the fair value hierarchy) considering the assumptions that market participants would make in valuing these securities. Assumptions such as estimated default rates and discount rates are used to determine the expected discounted cash flows to estimate fair value.

Capitalization of Costs

The Company’s capitalized internal costs related to development and redevelopment projects were comprised primarily of employee compensation and totaled $4.5 million and $4.6 million during the three months ended June 30, 2018 and 2017, respectively, and $9.5 million and $9.4 million for the six months ended June 30, 2018 and 2017, respectively. The Company capitalizes leasing commissions associated with the lease-up of development communities and amortizes the costs over the life of the leases. The amounts capitalized for leasing commissions are immaterial for all periods presented.

Co-investments

The Company owns investments in joint ventures (“co-investments”) in which it has significant influence, but its ownership interest does not meet the criteria for consolidation in accordance with U.S. GAAP. Therefore, the Company accounts for co-investments using the equity method of accounting. Under the equity method of accounting, the investment is carried at the cost of assets contributed, plus the Company's equity in earnings less distributions received and the Company's share of losses. The significant accounting policies of the Company’s co-investment entities are consistent with those of the Company in all material respects.

Upon the acquisition of a controlling interest of a co-investment, the co-investment entity is consolidated and the transaction will be accounted for as a business combination if the entity meets the definition of a business pursuant to ASU No. 2017-01, or an asset acquisition if the entity is not determined to be a business. A majority of the co-investments, excluding the preferred equity investments, compensate the Company for its asset management services and some of these investments may provide promote income if certain financial return benchmarks are achieved. Asset management fees are recognized when earned, and promote fees are recognized when the earnings events have occurred and the amount is determinable and collectible. Any promote fees are reflected in equity income from co-investments.

The Company reports investments in co-investments where accumulated distributions have exceeded the Company’s investment as distributions in excess of investments in co-investments in the accompanying condensed consolidated balance sheets. As of December 31, 2017, the net investment of one of the Company’s co-investments was less than zero as a result of financing distributions in excess of the Company's investment in that co-investment. As a result of the Company's adoption of ASU No. 2017-05 on January 1, 2018, the carrying value of this co-investment was greater than zero as of June 30, 2018.

Accounting Estimates

The preparation of condensed consolidated financial statements, in accordance with U.S. GAAP, requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to acquiring, developing and assessing the carrying values of its real estate portfolio, its investments in and advances to joint ventures and affiliates, its notes receivables, and its qualification as a real estate investment trust (“REIT”). The Company bases its estimates on historical experience, current market conditions, and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may vary from those estimates and those estimates could be different under different assumptions or conditions.

Senior Unsecured Debt

In March 2018, the Company issued $300.0 million of 30-year 4.500% senior unsecured notes. The interest is paid semi-annually in arrears on March 15 and September 15 of each year commencing on September 15, 2018 until the maturity date of March 15, 2048. The Company used the net proceeds of this offering to repay indebtedness under its unsecured lines of credit and for other general corporate and working capital purposes.

Subsequent Events

None.

(3)  Revenues

On January 1, 2018, the Company adopted ASU 2014-09, “Revenue from Contracts with Customers” using a modified retrospective transition method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods after January 1, 2018 are presented under the new standard, while prior period amounts are not adjusted and continue to be reported in accordance with the old revenue recognition standard.

Based on a full analysis of applicable contracts, the Company determined that the new standard did not have an impact to reported revenues from prior or current periods.

Revenue Recognition

Revenue from Leasing

The Company generates revenues primarily from leasing apartment homes to tenants. Such leasing revenues are recorded when due from tenants and are recognized monthly as they are earned, which is not materially different than on a straight-line basis. Apartment homes are rented under short-term leases (generally, lease terms of 6 to 12 months). Revenues from tenants leasing commercial space are recorded on a straight-line basis over the life of the respective lease.

The Company also generates other property-related revenue through the leasing of apartment homes, including storage income, pet rent, and other miscellaneous revenue. Similar to rental income, such revenues are recorded when due from tenants and recognized monthly as they are earned.

Revenue from Contracts with Customers

Apart from rental and other property-related revenue, revenues from contracts with customers are recognized as control of the promised services is passed to the customer.

For customer contracts related to management and other fees from affiliates (which includes asset management and property management), the transaction price and amount of revenue to be recognized is determined each quarter based on the management fee calculated and earned for that month or quarter. The contract will contain a description of the service and the fee percentage for management services. Payments from such services are one month or one quarter in arrears of the service performed.

The Company netted development and redevelopment fees of $1.0 million and $0.6 million against general and administrative expenses for the three months ended June 30, 2018 and 2017, respectively, and $1.9 million and $1.4 million for the six months ended June 30, 2018 and 2017, respectively.

In November 2017, the Company provided a $29.5 million related party bridge loan to a property acquired by BEX III. The note receivable accrued interest at 3.5% and was paid off in January 2018. The bridge loan was classified within notes and other receivables in the accompanying condensed consolidated balance sheets and had no amount outstanding as of June 30, 2018.

The Company’s Chairman and founder, Mr. George M. Marcus, is the Chairman of the Marcus & Millichap Company (“MMC”), which is a parent company of a diversified group of real estate service, investment, and development firms. Mr. Marcus is also the Co-Chairman of Marcus & Millichap, Inc. (“MMI”), and Mr. Marcus owns a controlling interest in MMI, a national brokerage firm listed on the New York Stock Exchange. 

In May 2018, the Company made a commitment to fund a $26.5 million preferred equity investment in an entity whose sponsors include an MMC affiliated company. The entity wholly owns a 400 apartment home community located in Ventura, CA. This investment will accrue interest based on a 10.25% preferred return. The investment is scheduled to mature in May 2023. As of June 30, 2018, the Company had funded $20.4 million of the commitment. The remaining committed amount will be funded if and when requested by the sponsors.

In March 2017, the Company converted its existing $15.3 million preferred equity investment in Sage at Cupertino, a 230 apartment home community located in San Jose, CA, into a 40.5% common equity ownership interest in the property. The Company issued DownREIT units to the other members, including an MMC affiliate, based on an estimated property valuation of $90.0 million. At the time of the conversion, the property was encumbered by $52.0 million of mortgage debt. As a result of this transaction, the Company consolidates the property, based on a VIE analysis performed by the Company.

In 2015, the Company made preferred equity investments totaling $20.0 million in three entities affiliated with MMC that own apartment communities in California. The Company earns a 9.5% preferred return on each such investment. One $5.0 million investment, which was scheduled to mature in 2022, was fully redeemed in 2017. The remaining two investments are scheduled to mature in 2022.

As described in Note 5, Notes and Other Receivables, the Company has provided short-term loans to affiliates. As of June 30, 2018 and December 31, 2017, $4.2 million and $5.1 million, respectively, of short-term loans remained outstanding due from joint venture affiliates and is classified within notes and other receivables in the accompanying condensed consolidated balance sheets. In November 2016, the Company provided a $6.6 million mezzanine loan to a limited liability company in which MMC holds a significant ownership interest through subsidiaries. The mezzanine loan is classified within notes and other receivables in the accompanying condensed consolidated balance sheets and had an outstanding balance of $6.6 million and $6.7 million as of June 30, 2018 and December 31, 2017, respectively.

(10) Derivative Instruments and Hedging Activities

As of June 30, 2018, the Company had entered into interest rate swap contracts with an aggregate notional amount of $175.0 million that effectively fixed the interest rate on the $175.0 million unsecured term loan at 2.3%. These derivatives qualify for hedge accounting.

As of June 30, 2018, the Company had interest rate caps, which are not accounted for as hedges, totaling a notional amount of $9.9 million that effectively limit the Company’s exposure to interest rate risk by providing a ceiling on the underlying variable interest rate for $9.9 million of the Company’s tax exempt variable rate debt.

As of June 30, 2018 and December 31, 2017, the aggregate carrying value of the interest rate swap contracts was an asset of $8.5 million and $5.4 million, respectively, and is included in prepaid expenses and other assets on the condensed consolidated balance sheets. The aggregate carrying value of the interest rate caps was zero on the condensed consolidated balance sheets as of both June 30, 2018 and December 31, 2017.

Hedge ineffectiveness related to cash flow hedges, which is included in interest expense on the condensed consolidated statements of income and comprehensive income, was not significant for the three and six months ended June 30, 2018 and 2017.

Additionally, the Company has entered into total return swaps that effectively convert $256.3 million of mortgage notes payable to a floating interest rate based on the Securities Industry and Financial Markets Association Municipal Swap Index (“SIFMA”) plus a spread. The total return swaps provide fair market value protection on the mortgage notes payable to the counterparties during the initial period of the total return swap until the Company's option to call the mortgage notes at par can be exercised. The Company can currently call all total return swaps, with $256.3 million of the outstanding debt at par. These derivatives do not qualify for hedge accounting and had a carrying and fair value of zero at both June 30, 2018 and December 31, 2017. These total return swaps are scheduled to mature between September 2021 and November 2022. The realized gains of $2.2 million and $2.5 million for the three months ended June 30, 2018 and 2017, respectively, and $4.5 million and $5.1 million for the six months ended June 30, 2018 and 2017, respectively, were reported in the condensed consolidated statements of income and comprehensive income as total return swap income.

Item 2: Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the Company’s Condensed Consolidated Financial Statements and accompanying Notes thereto included elsewhere herein and with the Company’s 2017 annual report on Form 10-K for the year ended December 31, 2017. Capitalized terms not defined in this section have the meaning ascribed to them elsewhere in this Quarterly Report on Form 10-Q. The Company makes statements in this section that are forward-looking statements within the meaning of the federal securities laws. For a complete discussion of forward-looking statements, see the section in this Form 10-Q entitled “Forward-Looking Statements.”

Essex is a self-administered and self-managed REIT that acquires, develops, redevelops, and manages apartment communities in selected residential areas located on the West Coast of the United States. Essex owns all of its interests in its real estate investments, directly or indirectly, through the Operating Partnership. Essex is the sole general partner of the Operating Partnership and, as of June 30, 2018, had an approximately 96.7% general partner interest in the Operating Partnership.

The Company’s investment strategy has two components: constant monitoring of existing markets, and evaluation of new markets to identify areas with the characteristics that underlie rental growth. The Company’s strong financial condition supports its investment strategy by enhancing its ability to quickly shift acquisition, development, redevelopment, and disposition activities to markets that will optimize the performance of the portfolio.

As of June 30, 2018, the Company owned or had ownership interests in 247 operating apartment communities, comprising 59,982 apartment homes, excluding the Company’s ownership in preferred equity interest co-investments, one operating commercial building with approximately 106,564 square feet, six active developments and three loan investments. The Company’s apartment communities are located in the following major regions:

Southern California (Los Angeles, Orange, San Diego, and Ventura counties)

Northern California (the San Francisco Bay Area)

SeattleMetro (Seattle metropolitan area)

As of June 30, 2018, the Company’s development pipeline was comprised of four consolidated projects under development, two unconsolidated joint venture projects under development, and various consolidated predevelopment projects aggregating 1,861 apartment homes, with total incurred costs of $0.6 billion, and estimated remaining project costs of $0.6 billion, $0.5 billion of which represents the Company's estimated remaining costs, for total estimated project costs of $1.2 billion.

The Company’s consolidated apartment communities are as follows:

	As of June 30, 2018			As of June 30, 2017
	Apartment Homes	%		Apartment Homes	%
Southern California	22,964	47	%	23,343	47	%
Northern California	15,970	32	%	15,848	32	%
Seattle Metro	10,238	21	%	10,238	21	%
Total	49,172	100	%	49,429	100	%

Co-investments, including Wesco I, Wesco III, Wesco IV, LLC, Wesco V, CPPIB, BEXAEW, BEX II, and BEX III communities, developments under construction, and preferred equity interest co-investment communities are not included in the table presented above for both periods.

Comparison of the Three Months Ended June 30, 2018 to the Three Months Ended June 30, 2017

The Company’s average financial occupancy for the Company’s stabilized apartment communities or "Same-Property" (stabilized properties consolidated by the Company for the quarters ended June 30, 2018 and 2017) was 96.7% and 96.4% for the three months ended June 30, 2018 and 2017, respectively. Financial occupancy is defined as the percentage resulting from dividing actual rental revenue by total potential rental revenue. Actual rental revenue represents contractual rental revenue pursuant to leases without considering delinquency and concessions. Total potential rental revenue 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. The Company believes that financial occupancy is a meaningful measure of occupancy because it considers the value of each vacant apartment home at its estimated market rate.

30

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. 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 disclosed by other REITs.

The Company does not take into account delinquency and concessions to calculate actual rent for occupied apartment homes and market rents for vacant apartment homes. The calculation of financial occupancy compares contractual rates for occupied apartment homes to estimated market rents for unoccupied apartment homes, and thus the calculation compares the gross value of all apartment homes excluding delinquency and concessions. For apartment 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 an apartment 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 revenue, is not considered the best metric to quantify occupancy.

The regional breakdown of the Company’s Same-Property portfolio for financial occupancy for the three months ended June 30, 2018 and 2017 is as follows:

	Three Months Ended June 30,
	2018		2017
Southern California	96.8	%	96.2	%
Northern California	96.7	%	96.7	%
Seattle Metro	96.3	%	96.2	%

Total Property Revenues		$	346,526	$	336,766	$	9,760	2.9	%

Same-Property Revenues increased by $8.7 million or 2.8% to $321.3 million in the second quarter of 2018 from $312.6 million in the second quarter of 2017. The increase was primarily attributable to an increase of 2.2% in average rental rates from $2,181 per apartment home in the second quarter of 2017 to $2,229 per apartment home in the second quarter of 2018. 

Non-Same Property Revenues increased by $1.1 million or 4.6% to $25.2 million in the second quarter of 2018 from $24.1 million in the second quarter of 2017. The increase was primarily due to revenue generated from Station Park Green - Phase I, a development community, that began producing rental income during the first quarter of 2018.

Management and other fees from affiliates remained relatively flat at $2.2 million in the second quarter of 2018 compared to $2.3 million in the second quarter of 2017.

Property operating expenses, excluding real estate taxes increased $2.3 million or 4.1% to $58.2 million for the second quarter of 2018 compared to $55.9 million for the second quarter of 2017 primarily due to an increase of $1.1 million in maintenance and repairs and an increase of $0.6 million in utilities expenses. Same-Property operating expenses, excluding real estate taxes, increased by $1.6 million or 3.0% for the second quarter of 2018 compared to the second quarter of 2017, primarily due to a $0.9 million increase in maintenance and repairs.

31

Real estate taxes increased $1.1 million or 3.2% to $36.0 million for the second quarter of 2018 compared to $34.9 million for the second quarter of 2017 primarily due to increases in tax rates and property valuations. Same-Property real estate taxes increased by $0.2 million or 0.7% to $34.3 million in the second quarter of 2018 compared to $34.1 million in the second quarter of 2017, primarily due to increases in tax rates and property valuations.

Corporate-level property management expenses increased $0.3 million or 4.0% to $7.8 million in the second quarter of 2018 compared to $7.5 million in the second quarter of 2017, primarily due to an increase in corporate-level property management and staffing costs supporting the communities.

Depreciation and amortization expense increased by $1.4 million or 1.2% to $119.3 million for the second quarter of 2018 compared to $117.9 million for the second quarter of 2017, primarily due to the completion of the Station Park Green - Phase I development during the first and second quarters of 2018 as well as an increase in redevelopment activity between the second quarter of 2017 and the second quarter of 2018.

Interest expense decreased $0.5 million or 0.9% to $56.3 million for the second quarter of 2018 compared to $56.8 million for the second quarter of 2017, primarily due to various debt that was paid off or matured and regular principal amortization during and after the second quarter of 2017, which resulted in a decrease in interest expense of $3.6 million for the second quarter of 2018. Additionally, there was a $0.9 million increase in capitalized interest in the second quarter of 2018, which was due to an increase in development costs as compared to the same period in 2017. These decreases to interest expense were partially offset by an increase in average outstanding debt primarily as a result of the issuance of $350.0 million senior unsecured notes due May 1, 2027 in April 2017 and $300.0 million senior unsecured notes due March 15, 2048 in March 2018, which resulted in an increase of $4.0 million interest expense for the second quarter of 2018.

Total return swap income of $2.2 million in the second quarter of 2018 consists of monthly settlements related to the Company's total return swap contracts that were entered into during 2015 in connection with issuing fixed rate tax-exempt mortgage notes. The decrease of $0.3 million for the second quarter of 2018 compared to the second quarter of 2017 was due to less favorable interest rates.

Interest and other income increased by $1.5 million or 27.8% to $6.9 million for the second quarter of 2018 compared to $5.4 million for the second quarter of 2017, primarily due to an increase in marketable securities and other interest income of $1.2 million in the second quarter of 2018.

Equity income from co-investments increased $4.7 million or 45.6% to $15.0 million for the second quarter of 2018 compared to $10.3 million for the second quarter of 2017, primarily due to an increase in income from preferred equity investments of $3.3 million and an increase of $1.3 million in income from early redemption of preferred equity investments.

Management and other fees from affiliates remained relatively flat at $4.5 million for the six months ended June 30, 2018 and 2017.

Property operating expenses, excluding real estate taxes increased $3.4 million or 3.0% to $115.4 million for the six months ended June 30, 2018 compared to $112.0 million for the six months ended June 30, 2017 primarily due to an increase of $1.5 million in maintenance and repairs as well as an increase of $1.4 million in administrative expenses. Same-Property operating expenses, excluding real estate taxes, increased by $2.4 million or 2.3% to $108.7 million for the six months ended June 30, 2018 compared to the six months ended June 30, 2017, primarily due to a $1.1 million increase in maintenance and repairs and an increase of $1.0 million in administrative expenses.

Real estate taxes increased $2.9 million or 4.1% to $73.7 million for the six months ended June 30, 2018 compared to $70.8 million for the six months ended June 30, 2017 due primarily to increases in tax rates and property valuations. Same-Property real estate taxes increased by $1.6 million or 2.4% to $68.7 million for the six months ended June 30, 2018 compared to $67.1 million for the six months ended June 30, 2017 primarily due to increases in tax rates and property valuations.

Corporate-level property management expenses increased $0.6 million or 4.0% to $15.6 million for the six months ended June 30, 2018 compared to $15.0 million for the six months ended June 30, 2017 primarily due to an increase in corporate-level property management and staffing costs supporting the communities.

Depreciation and amortization expense increased by $5.0 million or 2.1% to $238.4 million for the six months ended June 30, 2018 compared to $233.4 million for the six months ended June 30, 2017, primarily due to the completion of the Station Park Green - Phase I development during the first and second quarters of 2018, the consolidation of Sage at Cupertino in March 2017, as well as an increase in redevelopment activity between the second quarter of 2017 and the second quarter of 2018.

Interest expense decreased $0.3 million or 0.3% to $111.1 million for the six months ended June 30, 2018 compared to $111.4 million for the six months ended June 30, 2017, primarily due to various debt that was paid off or matured and regular principal amortization during and after the six months ended June 30, 2017, which resulted in a decrease in interest expense of $6.8 million for the six months ended June 30, 2018. Additionally, there was a $1.8 million increase in capitalized interest in the six months ended June 30, 2018, which was due to an increase in development costs as compared to the same period in 2017. These decreases to interest expense were partially offset by an increase in average outstanding debt primarily as a result of the issuance of $350.0 million senior unsecured notes due May 1, 2027 in April 2017 and $300.0 million senior unsecured notes due March 15, 2048 in March 2018, which resulted in an increase of $8.3 million interest expense for the six months ended June 30, 2018 and $2.7 million for the six months ended June 30, 2017.

33

Total return swap income of $4.5 million for the six months ended June 30, 2018 consists of monthly settlements related to the Company's total return swap contracts that were entered into during 2015 in connection with issuing fixed rate tax-exempt mortgage notes. The decrease of $0.6 million for the six months ended June 30, 2018 compared to the six months ended June 30, 2017 was due to less favorable interest rates.

Interest and other income increased by $0.7 million or 5.8% to $12.8 million for the six months ended June 30, 2018 compared to $12.1 million for the six months ended June 30, 2017, primarily due to an increase in marketable securities and other interest income of $2.1 million, partially offset by a decrease in the gain on sale of marketable securities of $1.1 million.

Equity income from co-investments increased $26.6 million or 125.5% to $47.8 million for the six months ended June 30, 2018 compared to $21.2 million for the six months ended June 30, 2017, primarily due to $20.5 million of promote income from the BEXAEW joint venture recognized during the first quarter of 2018 as well as an increase in income from preferred equity investments of $5.6 million.

Liquidity and Capital Resources

As of June 30, 2018, the Company had $160.9 million of unrestricted cash and cash equivalents and $207.2 million in marketable securities, of which $89.2 million were equity securities or available for sale debt securities. 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 the next twelve months. The timing, source and amounts of cash flows provided by financing activities and used in investing activities are sensitive to changes in interest rates and other fluctuations in the capital markets environment, which can affect the Company's plans for acquisitions, dispositions, development and redevelopment activities.

As of June 30, 2018, Fitch Ratings (“Fitch”), Moody’s Investor Service (“Moody's”), and Standard and Poor's (“S&P”) credit agencies rate the Company and the Operating Partnership, BBB+/Positive, Baa1/Stable, and BBB+/Stable, respectively.

As of June 30, 2018, the Company had two unsecured lines of credit aggregating $1.24 billion. In January 2018, the Company’s unsecured credit facility was amended, and the line’s capacity was increased from $1.0 billion to $1.2 billion. As of June 30, 2018, there was no amount outstanding on this unsecured line of credit. The underlying interest rate is based on a tiered rate structure tied to the Company's credit ratings and was LIBOR plus 0.875% as of June 30, 2018. In connection with the January 2018 amendment, the scheduled maturity date of this facility was extended to December 2021, with one 18-month extension, exercisable at the Company's option. In January 2018, the Company’s working capital unsecured line of credit was also amended, and the line’s capacity was increased from $25.0 million to $35.0 million. As of June 30, 2018, there was $2.7 million outstanding on this unsecured line of credit. The underlying interest rate on the $35.0 million line is based on a tiered rate structure tied to the Company's credit ratings and was LIBOR plus 0.875% as of June 30, 2018. In connection with the January 2018 amendment, the scheduled maturity date of this facility was extended to January 2020.

In March 2018, the Company issued $300.0 million of 30-year 4.500% senior unsecured notes. The interest is paid semi-annually in arrears on March 15 and September 15 of each year commencing on September 15, 2018 until the maturity date of March 15, 2048. The Company used the net proceeds of this offering to repay indebtedness under its unsecured credit facilities and for other general corporate and working capital purposes.

The Company has entered into equity distribution agreements with Cantor Fitzgerald & Co, Barclays Capital Inc., BMO Capital Markets Corp., BNP Paribas Securities Corp., Capital One Securities, Inc., Citigroup Global Markets Inc., Jefferies LLC, J.P. Morgan Securities LLC, Mitsubishi UFJ Securities (USA), Inc., and UBS Securities LLC. During the six months ended June 30, 2018, the Company did not issue any shares pursuant to its equity distribution program. Under this program, the Company may from time to time sell shares of common stock into the existing trading market at current market prices, and the Company anticipates using the net proceeds, which are contributed to the Operating Partnership, to pay down debt, acquire apartment communities, fund the development pipeline and for other general corporate purposes. As of June 30, 2018, the Company may sell an additional 4,654,556 shares under the current equity distribution program.

In December 2015, the Company’s board of directors authorized a stock repurchase plan to allow the Company to acquire shares in an aggregate of up to $250.0 million. During the six months ended June 30, 2018, the Company repurchased 16,834 shares of its common stock totaling $3.8 million, including commissions, at an average price of $224.13 per share. As of June 30, 2018, the Company had $245.2 million of purchase authority remaining under the stock repurchase plan.

Essex pays quarterly dividends from cash available for distribution. Until it is distributed, cash available for distribution is invested by the Company primarily in investment grade securities held available for sale or is used by the Company to reduce balances outstanding under its line of credit. 

Development and Predevelopment Pipeline

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 June 30, 2018, the Company’s development pipeline was comprised of four consolidated projects under development, two unconsolidated joint venture projects under development and various consolidated predevelopment projects, aggregating 1,861 apartment homes, with total incurred costs of $0.6 billion, and estimated remaining project costs of approximately $0.6 billion, $0.5 billion of which represents the Company's estimated remaining costs, for total estimated project costs of $1.2 billion.

The Company expects to fund the development and predevelopment pipeline by using a combination of some or all of the following sources: its working capital, amounts available on its credit facilities, construction loans, net proceeds from public and private equity and debt issuances, and proceeds from the disposition of assets, if any.

Redevelopment Pipeline

The Company defines redevelopment communities as existing properties owned or recently acquired, which have been targeted for additional investment by the Company with the expectation of increased financial returns through property improvement. During redevelopment, apartment homes may not be available for rent and, as a result, may have less than stabilized operations. As of June 30, 2018, the Company had ownership interests in five major redevelopment communities aggregating 1,727 apartment homes with estimated redevelopment costs of $140.1 million, of which approximately $36.4 million remains to be expended. The Company has the ability to cease funding of the redevelopment pipeline as needed.

Derivative Activity

The Company uses interest rate swaps, interest rate caps, and total return swap contracts to manage certain interest rate risks. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The fair values of interest rate swaps and total return swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements.

Alternative Capital Sources

The Company utilizes co-investments as an alternative source of capital for investments in both operating and development communities. As of June 30, 2018, the Company had an interest in 814 apartment homes in communities actively under development with joint ventures for total estimated costs of $0.6 billion. Total estimated remaining costs total approximately $0.3 billion, of which the Company estimates that its remaining investment in these development joint ventures will be approximately $0.2 billion. In addition, the Company had an interest in 10,810 apartment homes of operating communities with joint ventures for a total book value of $0.9 billion as of June 30, 2018.

Off-Balance Sheet Arrangements

The Company has various unconsolidated interests in certain joint ventures. The Company does not believe that these unconsolidated investments have a materially different impact on its liquidity, cash flows, capital resources, credit or market risk than its consolidated operations. See Note 4, Co-investments, in the Notes to Condensed Consolidated Financial Statements for carrying values and combined summarized financial information of these unconsolidated investments.

Critical Accounting Policies and Estimates

The preparation of condensed consolidated financial statements, in accordance with U.S. GAAP, requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. The Company defines critical accounting policies as those accounting policies that require the

35

Company’s management to exercise their most difficult, subjective and complex judgments. The Company’s critical accounting policies and estimates relate principally to the following key areas: (i) accounting for business combinations; (ii) consolidation under applicable accounting standards for entities that are not wholly owned; (iii) assessing the carrying values of the Company's real estate properties and investments in and advances to joint ventures and affiliates; and (iv) internal cost capitalization. The Company bases its estimates on historical experience, current market conditions, and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from those estimates made by management.

The Company’s critical accounting policies and estimates have not changed materially from the information reported in Note 2, Summary of Critical and Significant Accounting Policies, in the Company’s annual report on Form 10-K for the year ended December 31, 2017.

Funds from Operations Attributable to Common Stockholders and Unitholders

Funds from Operations Attributable to Common Stockholders and Unitholders (“FFO”) is a financial measure that is commonly used in the REIT industry.  The Company presents FFO as a supplemental operating performance measure. FFO is not used by the Company as, nor should it be considered to be, an alternative to net earnings computed under U.S. GAAP as an indicator of the Company’s operating performance or as an alternative to cash from operating activities computed under U.S. GAAP as an indicator of the Company’s ability to fund its cash needs.

FFO is not meant to represent a comprehensive system of financial reporting and does not present, nor does it intend to present, a complete picture of the Company's financial condition and operating performance. The Company believes that net earnings computed under U.S. GAAP is the primary measure of performance and that FFO is only meaningful when it is used in conjunction with net earnings. The Company considers FFO and FFO excluding non-recurring items and acquisition costs (referred to as “Core FFO”) to be useful financial performance measurements of an equity REIT because, together with net income and cash flows, FFO and Core FFO provide investors with additional bases to evaluate operating performance and ability of a REIT to incur and service debt and to fund acquisitions and other capital expenditures and ability to pay dividends. Further, the Company believes that its consolidated financial statements, prepared in accordance with U.S. GAAP, provide the most meaningful picture of its financial condition and its operating performance.

In calculating FFO, the Company follows the definition for this measure published by the National Association of Real Estate Investment Trusts (“NAREIT”), which is the leading REIT industry association. The Company believes that, under the NAREIT FFO definition, the two most significant adjustments made to net income are (i) the exclusion of historical cost depreciation and (ii) the exclusion of gains and losses from the sale of previously depreciated properties. The Company agrees that these two NAREIT adjustments are useful to investors for the following reasons:

(a) historical cost accounting for real estate assets in accordance with U.S. GAAP assumes, through depreciation charges, that the value of real estate assets diminishes predictably over time. NAREIT stated in its White Paper on Funds from Operations “since real estate asset values have historically risen or fallen with market conditions, many industry investors have considered presentations of operating results for real estate companies that use historical cost accounting to be insufficient by themselves.” Consequently, NAREIT’s definition of FFO reflects the fact that real estate, as an asset class, generally appreciates over time and depreciation charges required by U.S. GAAP do not reflect the underlying economic realities.

(b) REITs were created as a legal form of organization in order to encourage public ownership of real estate as an asset class through investment in firms that were in the business of long-term ownership and management of real estate.  The exclusion, in NAREIT’s definition of FFO, of gains and losses from the sales of previously depreciated operating real estate assets allows investors and analysts to readily identify the operating results of the long-term assets that form the core of a REIT’s activity and assists in comparing those operating results between periods.

Management believes that it has consistently applied the NAREIT definition of FFO to all periods presented. However, there is judgment involved and other REITs’ calculation of FFO may vary from the NAREIT definition for this measure, and thus their disclosure of FFO may not be comparable to the Company’s calculation.

(1) Interest rate swaps generally are adjusted to fair value through other comprehensive income (loss). However, because certain of the Company's interest rate swaps do not have a 0% LIBOR floor, while related hedged debt in these cases is subject to a 0% LIBOR floor, the portion of the change in fair value of these interest rate swaps attributable to this mismatch, if any, is recorded as a non-cash interest rate hedge ineffectiveness through interest expense.

(2) Assumes conversion of all dilutive outstanding operating partnership interests in the Operating Partnership and excludes all DownREIT limited partnership units for which the Operating Partnership has the ability and intention to redeem the units for cash and does not consider them to be common stock equivalents.

Net Operating Income

Net operating income (“NOI”) and Same-Property NOI are considered by management to be an important supplemental performance measure to earnings from operations included in the Company’s consolidated statements of income. The presentation of Same-Property NOI assists with the presentation of the Company’s operations prior to the allocation of depreciation and any corporate-level or financing-related costs. NOI reflects the operating performance of a community and allows for an easy comparison of the operating performance of individual communities or groups of communities. In addition, because prospective buyers of real estate have different financing and overhead structures, with varying marginal impacts to overhead by acquiring real estate, NOI is considered by many in the real estate industry to be a useful measure for determining

38

the value of a real estate asset or group of assets. The Company defines Same-Property NOI as Same-Property revenue less Same-Property operating expenses, including property taxes. Please see the reconciliation of earnings from operations to Same-Property NOI, which in the table below is the NOI for stabilized properties consolidated by the Company for the periods presented ($ in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,

Item 3: Quantitative and Qualitative Disclosures About Market Risks

Interest Rate Hedging Activities

The Company’s objective in using derivatives is to add stability to interest expense and to manage its exposure to interest rate movements or other identified risks. To accomplish this objective, the Company uses interest rate swaps as part of its cash flow hedging strategy. As of June 30, 2018, the Company has entered into five interest rate swap contracts to mitigate the risk of changes in the interest-related cash outflows on $175.0 million of the Company's unsecured term debt. As of June 30, 2018, the Company also had $269.9 million of secured variable rate indebtedness, of which $9.9 million is subject to interest rate cap protection. All of the Company's interest rate swaps are designated as cash flow hedges as of June 30, 2018. The following table summarizes the notional amount, carrying value, and estimated fair value of the Company’s cash flow hedge derivative instruments used to hedge interest rates as of June 30, 2018. The notional amount represents the aggregate amount of a particular security that is currently hedged at one time, but does not represent exposure to credit, interest rates, or market risks. The table also includes a sensitivity analysis to demonstrate the impact on the Company’s derivative instruments from an increase or decrease in 10-year Treasury bill interest rates by 50 basis points, as of June 30, 2018.

				Carrying and		Estimated Carrying Value
	Notional		Maturity	Estimated		50		-50
($ in thousands)	Amount		Date Range	Fair Value		Basis Points		Basis Points
Cash flow hedges:
Interest rate swaps	$	175,000	2022	$	8,473	$	11,378	$	5,602
Interest rate caps	9,924		2019	—		—		—
Total cash flow hedges	$	184,924	2019-2022	$	8,473	$	11,378	$	5,602

Additionally, the Company has entered into total return swap contracts, with an aggregate notional amount of $256.3 million that effectively convert $256.3 million of fixed mortgage notes payable to a floating interest rate based on the SIFMA plus a spread and have a carrying value of zero at June 30, 2018. The Company is exposed to insignificant interest rate risk on these swaps as the related mortgages are callable, at par, by the Company, co-terminus with the termination of any related swap. These derivatives do not qualify for hedge accounting.

39

Interest Rate Sensitive Liabilities

The Company is exposed to interest rate changes primarily as a result of its lines of credit and long-term debt used to maintain liquidity and fund capital expenditures and expansion of the Company's real estate investment portfolio and operations. The Company’s interest rate risk management objective is to limit the impact of interest rate changes on earnings and cash flows and to lower its overall borrowing costs. To achieve its objectives, the Company borrows primarily at fixed rates and may enter into derivative financial instruments such as interest rate swaps, caps, and treasury locks in order to mitigate its interest rate risk on a related financial instrument. The Company does not enter into derivative or interest rate transactions for speculative purposes.

The Company’s interest rate risk is monitored using a variety of techniques. The table below presents the principal amounts and weighted average interest rates by year of expected maturity to evaluate the expected cash flows.

For the Years Ended	2018			2019		2020		2021		2022		Thereafter		Total			Fair value
($ in thousands, except for interest rates)
Fixed rate debt	$	119,502		606,251		694,273		544,138		341,692		2,768,858		$	5,074,714		$	5,055,937
Average interest rate	5.8		%	4.4	%	5.0	%	4.5	%	3.8	%	3.8	%	4.2		%
Variable rate debt (1)	$	277		592		3,318		708		350,774		266,950		$	622,619		$	618,156
Average interest rate	2.5		%	2.5	%	2.7	%	2.5	%	2.8	%	2.3	%	2.6		%

(1) $175.0 million is subject to interest rate swap agreements, $9.9 million is subject to interest rate caps, and $256.3 million is subject to total return swaps.

The table incorporates only those exposures that exist as of June 30, 2018. It does not consider those exposures or positions that could arise after that date. As a result, the Company's ultimate realized gain or loss, with respect to interest rate fluctuations and hedging strategies would depend on the exposures that arise prior to settlement.

2018 STOCK AWARD INCENTIVE AND COMPENSATION PLAN

NON-EMPLOYEE DIRECTOR EQUITY AWARD

RESTRICTED STOCK AWARD AGREEMENT

1.Grant of Restricted Shares.

(a)    Award. Essex Property Trust, Inc., a Maryland corporation (the “Company”), hereby grants to the Grantee (the “Grantee”) named in the Notice of Restricted Stock Award (the “Notice”), an award (the “Award”) of the number of shares of Common Stock set forth in the Notice (the “Restricted Shares”), subject to the terms and provisions of the Notice, this Restricted Stock Award Agreement (the “Agreement”) and the Company’s 2018 StockAward and Incentive Compensation Plan, as amended from time to time (the “Plan”), all of which are incorporated herein by reference.

(b)    Definitions. Unless otherwise defined herein, the terms defined in the Plan shall have the same defined meanings in this Agreement.

(c)    Incorporation of Terms of Plan. The Award of Restricted Shares is subject to the terms and conditions of the Plan, each of which is incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan shall control.

2.Consideration. The Restricted Shares have been issued to the Grantee in consideration for prior service with the Company.

3.Conditions and Restrictions.

(a)Vesting. Subject to the conditions and restrictions of this Section 3, the Restricted Shares shall be fully vested as of the date of grant set forth in the Notice (the “Grant Date”).

(b)Transfer Restrictions. Notwithstanding anything in the Notice or this Agreement and notwithstanding the fully vested status of the Restricted Shares, the Restricted Shares granted to the Grantee hereunder may not be sold, transferred by gift, pledged, hypothecated, or otherwise transferred or disposed of by the Grantee (including withholding of Shares to satisfy tax withholding obligations) during the Transfer Restriction Period. Any attempt to transfer Restricted Shares in violation of this Section 3 will be null and void and will be disregarded. “Transfer Restriction Period” for purposes of this Agreement means the period commencing on the Grant Date and ending on the first anniversary thereof.

4.Issuance of Restricted Shares. As of the Grant Date, the Restricted Shares will be issued by the Company and registered in the Grantee’s name on the stock transfer books of the Company. The Restricted Shares shall remain in the physical custody of the Company or its designee at all times until the expiration of the Transfer Restriction Period and all other terms and conditions in this Agreement have been satisfied. Only whole shares of Common Stock shall be issued.

5.Refusal to Transfer. The Company shall not be required (i) to transfer on its books any shares of Common Stock that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such shares of Common Stock or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such shares of Common Stock shall have been so transferred.

6.Shareholder Rights. Subject to the restrictions set forth in the Plan and the Agreement, Grantee shall possess all the rights and privileges of a shareholder of the Company for all the Restricted Shares while the Award is subject to stop-transfer instructions, or otherwise held by the Company or its designee, including the right to vote and receive dividends with respect to the Restricted Shares.

7.Taxes. The Grantee is advised to review with his or her own tax advisors the Federal, state, local and, if applicable, non-U.S. tax consequences of the transactions contemplated by the grant of the Restricted Shares. The Grantee is relying solely on such advisors and is not relying in any part on any statement or representation of the Company or any of its agents. Neither the Company nor any Related Entity shall be responsible for withholding any income tax, social security, unemployment, disability insurance or other tax obligations that become legally due by the Grantee in connection with any aspect of the Restricted Shares, including the award of the Restricted Shares, vesting or issuance of the Restricted Shares, or sale of the Restricted Shares (“Tax-Related Items”). The Grantee is solely responsible for timely reporting all income derived from the Restricted Shares on the Grantee’s personal tax return and paying all Tax-Related Items, and shall indemnify the Company and all Related Entities and hold them harmless from and against all claims, damages, losses and expenses, including reasonable fees and expenses of attorneys, relating to any obligation imposed by law on the Company or any Related Entity to pay any Tax-Related Items.

If the Company becomes obligated to withhold any Tax-Related Items, prior to any relevant taxable or tax withholding event, as applicable, the Grantee shall pay or make adequate arrangements satisfactory to the Company to satisfy all Tax-Related Items. In this regard, the Grantee hereby authorizes the Company or its agent, at the Company’s discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following methods:

(a)    withholding from wages or other cash compensation otherwise payable to the Grantee by the Company, and/or

(b)    following the expiration of the Transfer Restriction Period, withholding from the proceeds of the sale of Restricted Shares, either through a voluntary sale or through a mandatory sale arranged by the Company (on the Grantee’s behalf pursuant to this authorization); and/or

(c)    following the expiration of the Transfer Restriction Period, delivery of Restricted Shares subject to the Award.

Depending on the withholding method, the Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates, including maximum applicable rates, in which case the Grantee will receive a refund of any over-withheld amount in cash and will have no entitlement to the equivalent in Shares. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Grantee will be deemed to have been issued the full number of Restricted Shares, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of the Grantee’s participation in the Plan.

The Grantee further acknowledges that the Company (1) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Restricted Shares, including, but not limited to, the grant, vesting or issuance of the Restricted Shares, the subsequent sale of Shares acquired pursuant to such issuance and the receipt of any dividends and/or any dividend equivalents; and (2) does not commit to and is under no obligation to structure the terms of the Award or any aspect of the Restricted Shares to reduce or eliminate the Grantee’s liability for Tax-Related Items or achieve any particular tax result.

8.Stop-Transfer Notices. In order to ensure compliance with the restrictions on transfer set forth in this Agreement and the Notice, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

9.Additional Conditions to Issuance of Shares of Common Stock. If at any time the Company determines, in its discretion, that the listing, registration or qualification of the shares of Common Stock upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of shares to Grantee (or his estate), such issuance will not occur unless and until such listing, registration, qualification, consent or approval will have been effected or obtained free of any conditions not acceptable to the Company. The Company will make all reasonable efforts to meet the requirements of any such state or federal law or securities exchange and to obtain any such consent or approval of any such governmental authority.

10.Entire Agreement: Governing Law. The Notice, the Plan and this Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and the Grantee with respect to the subject matter hereof, and may not be modified adversely to the Grantee’s interest except by means

2

of a writing signed by the Company and the Grantee. Nothing in the Notice, the Plan or this Agreement (except as expressly provided therein) is intended to confer any rights or remedies on any persons other than the parties. The Notice, the Plan and this Agreement are to be construed in accordance with and governed by the internal laws of the State of California without giving effect to any choice of law rule that would cause the application of the laws of any jurisdiction other than the internal laws of the State of California to the rights and duties of the parties.

11.Conformity to Securities Laws. The Grantee acknowledges that the Plan and this Agreement are intended to conform to the extent necessary with all provisions of the Securities Act, and the Exchange Act, and any and all regulations and rules promulgated thereunder by the U.S. Securities and Exchange Commission, including, without limitation, Rule 16b-3 under the Exchange Act.

To the extent permitted by Applicable Law, the Plan and this Agreement shall be deemed amended to the extent necessary to conform to such laws, rules and regulations.

12.Headings. The captions used in the Notice and this Agreement are inserted for convenience and shall not be deemed a part of the Award for construction or interpretation.

13.Administration and Interpretation. The grant of the Award and the vesting of the Restricted Shares shall be administered in accordance with the provisions of the Plan, as the same may be amended from time to time. Any question or dispute regarding the administration or interpretation of the Notice, the Plan or this Agreement shall be submitted by the Grantee or by the Company to the Administrator. The resolution of such question or dispute by the Administrator shall be final and binding on all persons.

14.Plan Governs. This Agreement is subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Agreement and one or more provisions of the Plan, the provisions of the Plan will govern.

15.Venue and Waiver of Jury Trial. The parties agree that any suit, action, or proceeding arising out of or relating to the Notice, the Plan or this Agreement shall be brought in the United States District Court for the Northern District of California (or should such court lack jurisdiction to hear such action, suit or proceeding, in a California state court in the County of Santa Clara) and that the parties shall submit to the jurisdiction of such court. The parties irrevocably waive, to the fullest extent permitted by law, any objection the party may have to the laying of venue for any such suit, action or proceeding brought in such court. THE PARTIES ALSO EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR MAY HAVE TO A JURY TRIAL OF ANY SUCH SUIT, ACTION OR PROCEEDING. If any one or more provisions of this Section 15 shall for any reason be held invalid or unenforceable, it is the specific intent of the parties that such provisions shall be modified to the minimum extent necessary to make it or its application valid and enforceable.

16.Notices. Any notice required or permitted hereunder shall be given in writing and shall be deemed effectively given upon personal delivery, upon deposit for delivery by an internationally recognized express mail courier service or upon deposit in the United States mail by certified mail (if the parties are within the United States), with postage and fees prepaid, addressed to the other party at its address as shown in these instruments, or to such other address as such party may designate in writing from time to time to the other party.

17.Restrictions on Resale. The Grantee hereby agrees not to sell any Shares at a time when Applicable Laws, Company policies or an agreement between the Company and its underwriters prohibit a sale. This restriction will apply as long as the Grantee’s Continuous Service continues and for such period of time after the termination of the Grantee’s Continuous Service as the Company may specify.

18.Successors and Assigns. The Company may assign any of its rights under this Agreement to single or multiple assignees, and this Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Agreement shall be binding upon the Grantee and his or her heirs, executors, administrators, successors and assign.

3

19.Severability. Should any provision of the Notice, the Plan or this Agreement be determined to be illegal or unenforceable, such provision shall be enforced to the fullest extent allowed by law and the other provisions shall nevertheless remain effective and shall remain enforceable.

20.No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Grantee’s participation in the Plan or the Grantee’s acquisition or sale of the underlying Shares. The Grantee is hereby advised to consult with his or her own personal tax, legal and financial advisors regarding the Grantee’s participation in the Plan before taking any action related to the Plan.

21.Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means.

ESSEX PROPERTY TRUST, INC.
2018 STOCK AWARD AND INCENTIVE COMPENSATION PLAN

NON-EMPLOYEE DIRECTOR EQUITY AWARD

NON-QUALIFIED STOCK OPTION AWARD AGREEMENT

1.Grant of Option. Essex Property Trust, Inc., a Maryland corporation (the “Company”), hereby grants to the Grantee (the “Grantee”) named in the Notice of Non-Qualified Stock Option Award (the “Notice”), an option (the “Option”) to purchase the Total Number of Shares of Common Stock subject to the Option (the “Shares”) set forth in the Notice, at the Exercise Price per Share set forth in the Notice (the “Exercise Price”), subject to the terms and provisions of the Notice, this Non-Qualified Stock Option Award Agreement (the “Option Agreement”) and the Company’s 2018 Stock Award and Incentive Compensation Plan (the “Plan”), as amended from time to time, all of which are incorporated herein by reference. Unless otherwise defined herein, the terms defined in the Plan shall have the same defined meanings in this Option Agreement.

The Option is intended to be treated as a Non-Qualified Stock Option and not qualify as an Incentive Stock Option as defined in Section 422 of the Code.

2.Exercise of Option.

(a) Right to Exercise.

(i)The Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice and with the applicable provisions of the Plan and this Option Agreement. The Option shall be subject to the provisions of Section 11 of the Plan relating to the exercisability or termination of the Option in the event of a Change in Control. The Grantee shall be subject to reasonable limitations on the number of requested exercises during any monthly or weekly period as determined by the Administrator. In no event shall the Company issue fractional Shares.

(ii)Any Shares issued upon exercise of the Option shall be subject to the transfer restrictions set forth in Section 3(b), below.

(b)Method of Exercise. The Option shall be exercisable only by delivery of an exercise notice (a form of which is attached as Exhibit A) or by such other procedure as specified from time to time by the Administrator which shall state the election to exercise the Option, the whole number of Shares in respect of which the Option is being exercised, and such other provisions as may be required by the Administrator. The exercise notice shall be delivered in person, by certified mail, or by such other method (including electronic transmission) as determined from time to time by the Administrator to the Company accompanied by payment of the Exercise Price. The Option shall be deemed to be exercised upon receipt by the Company of such notice accompanied by the Exercise Price, which, to the extent selected, shall be deemed to be satisfied by use of the broker-dealer sale and remittance procedure to pay the Exercise Price provided in Section 4(d), below.

(c)Taxes. The Grantee is advised to review with his or her own tax advisors the Federal, state, local and, if applicable, non-U.S. tax consequences of the transactions contemplated by the grant of the Option. The Grantee is relying solely on such advisors and is not relying in any part on any statement or representation of the Company or any of its agents. Neither the Company nor any Related Entity shall be responsible for withholding any income tax, social

security, unemployment, disability insurance or other tax obligations that become legally due by the Grantee in connection with any aspect of the Option, including the grant of the Option, vesting of the Option, or sale of the underlying Shares (“Tax-Related Items”). The Grantee is solely responsible for timely reporting all income derived from the Option on the Grantee’s personal tax return and paying all Tax-Related Items, and shall indemnify the Company and all Related Entities and hold them harmless from and against all claims, damages, losses and expenses, including reasonable fees and expenses of attorneys, relating to any obligation imposed by law on the Company or any Related Entity to pay any Tax-Related Items.If the Company becomes obligated to withhold any Tax-Related Items, prior to any relevant taxable or tax withholding event, as applicable, the Grantee shall pay or make adequate arrangements satisfactory to the Company to satisfy all Tax-Related Items. In this regard, the Grantee hereby authorizes the Company or its agent, at the Company’s discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following methods:

(i)withholding from director fees or other cash compensation otherwise payable to the Grantee by the Company or the Company’s employer (if different); and/or

(ii)following the expiration of the Transfer Restriction Period, withholding from the proceeds of the sale of Shares acquired upon exercise of the Option, either through a voluntary sale or through a mandatory sale arranged by the Company (on the Grantee’s behalf pursuant to this authorization); and/or

(iii)following the expiration of the Transfer Restriction Period (as defined below), withholding in Shares to be issued upon exercise of the Option.

Depending on the withholding method, the Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates, including maximum applicable rates, in which case the Grantee will receive a refund of any over-withheld amount in cash and will have no entitlement to the equivalent in Shares. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Grantee will be deemed to have been issued the full number of Shares subject to the exercised portion of the Option, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of the Grantee’s participation in the Plan.

The Grantee further acknowledges that the Company (1) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option, including, but not limited to, the grant or vesting of the Option, the issuance of Shares under the Option, the subsequent sale of Shares acquired pursuant to such issuance and the receipt of any dividends and/or any dividend equivalents; and (2) does not commit to and is under no obligation to structure the terms of the Option or any aspect of the Option to reduce or eliminate the Grantee’s liability for Tax-Related Items or achieve any particular tax result.

3.Restrictions.

(a)Restrictions on Exercise. The Option may not be exercised if the issuance of the Shares subject to the Option upon such exercise would constitute a violation of any Applicable Laws.

(b)Transfer Restrictions. Notwithstanding anything in the Notice or this Option Agreement or the vested status of the Option, any Shares that are issued pursuant to the exercise of an Option may not be sold, transferred by gift, pledged, hypothecated, or otherwise transferred or disposed of by the Grantee (including withholding Shares issuable under the Option to satisfy tax withholding obligations and the sale of Shares pursuant to a broker-assisted “cashless exercise,” as contemplated under Section 4(d), below) during the Transfer Restriction Period. Any attempt to transfer Shares in violation of this Section 3(b) will be null and void and will be disregarded. “Transfer Restriction Period” for purposes of this Option Agreement means the period commencing on the Date of Award (as defined in the Notice) and ending on the first anniversary thereof.

2

(i)    Shares Issued During Transfer Restriction Period. Any Shares issued upon exercise of the Option prior to the expiration of the Transfer Restriction Period shall be registered in the Grantee’s name on the stock transfer books of the Company and shall remain in the physical custody of the Company or its designee at all times until the expiration of the Transfer Restriction Period and all other terms and conditions in this Option Agreement have been satisfied. Only whole Shares shall be issued.

(ii)    Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Option Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.

(iii)    Stop-Transfer Notices. In order to ensure compliance with the restrictions on transfer set forth in this Section 3, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

(iv)    Shareholder Rights. Subject to the restrictions set forth in the Plan and this Option Agreement, Grantee shall possess all the rights and privileges of a shareholder of the Company for all the Shares that are issued upon the exercise of the Option while the Shares are subject to stop-transfer instructions, or otherwise held by the Company or its designee, including the right to vote and receive dividends with respect to the Shares.

4.Method of Payment. Payment of the Exercise Price shall be by any of the following, or a combination thereof, at the election of the Grantee; provided, however, that such exercise method does not then violate any Applicable Laws:

(a) cash;

(b) check;

(c)following the expiration of the Transfer Restriction Period, surrender of Shares or delivery of a properly executed form of attestation of ownership of Shares as the Administrator may require which have a Fair Market Value on the date of surrender or attestation equal to the aggregate Exercise Price of the Shares as to which the Option is being exercised; or

(d)following the expiration of the Transfer Restriction Period, payment through a broker-dealer sale and remittance procedure pursuant to which the Grantee (i) shall provide written instructions to a Company-designated brokerage firm to effect the immediate sale of some or all of the purchased Shares and remit to the Company sufficient funds to cover the aggregate Exercise Price payable for the purchased Shares and (ii) shall provide written directives to the Company to deliver the certificates for the purchased Shares directly to such brokerage firm in order to complete the sale transaction.

5.Termination or Change of Continuous Service. In the event the Grantee’s Continuous Service terminates, the Grantee may exercise the Option, but only prior to the expiration of the Post-Termination Exercise Period set forth in the Notice. In no event, however, shall the Option be exercised

later than the Expiration Date set forth in the Notice. In the event of the Grantee’s change in status from Employee, Director or Consultant to any other status of Employee, Director or Consultant, the Option shall remain in effect. Except as provided in Sections 6, 7 and 8 below, if the Grantee does not exercise the Option prior to the expiration of the Post-Termination Exercise Period, the Option shall terminate.

3

6.Retirement of Grantee. If the Grantee’s Continuous Service terminates at a time when the Grantee’s combined age and years of Continuous Service is equal to or greater than 68, then the Grantee may exercise the Option, but only prior to the expiration of the period ending on the third anniversary of date the Grantee’s Continuous Service terminates (but in no event later than the Expiration Date). If the Grantee does not exercise the Option prior to the expiration of the time specified herein, the Option shall terminate.

7.Disability of Grantee. In the event the Grantee’s Continuous Service terminates as a result of his or her Disability, the Grantee may exercise the Option, but only prior to the expiration of twelve (12) months from the date the Grantee’s Continuous Service terminates (and in no event later than the Expiration Date). If the Grantee does not exercise the Option prior to the expiration of the time specified herein, the Option shall terminate.

8.Death of Grantee. In the event of the termination of the Grantee’s Continuous Service as a result of his or her death, or in the event of the Grantee’s death during the Post-Termination Exercise Period or during the twelve (12) month period following the Grantee’s termination of Continuous Service as a result of his or her Disability, the person who acquired the right to exercise the Option pursuant to Section 9 below may exercise the Option prior to the expiration of twelve (12) months from the date of death (but in no event later than the Expiration Date). If the Option is not exercised prior to the expiration of the time specified herein, the Option shall terminate.

9.Transferability of Option. The Option may not be transferred in any manner other than by will or by the laws of descent and distribution; provided, however, that the Option may be transferred during the lifetime of the Grantee to the extent and in the manner authorized by the Administrator. Notwithstanding the foregoing, the Grantee may designate one or more beneficiaries of the Grantee’s Option in the event of the Grantee’s death on a beneficiary designation form provided by the Administrator. Following the death of the Grantee, the Option, to the extent provided in Section 8 above, may be exercised (a) by the person or persons designated under the deceased Grantee’s beneficiary designation or (b) in the absence of an effectively designated beneficiary, by the Grantee’s legal representative or by any person empowered to do so under the deceased Grantee’s will or under the then applicable laws of descent and distribution. The Option may not be pledged, alienated, attached or otherwise encumbered, and any purported pledge, alienation, attachment or encumbrance of the Option shall be void and unenforceable against the Company or any Related Entity. The terms of the Option shall be binding upon the executors, administrators, heirs, successors and transferees of the Grantee.

10.Term of Option. The Option must be exercised no later than the Expiration Date set forth in the Notice or such earlier date as otherwise provided herein. After the Expiration Date or such earlier date, the Option shall be of no further force or effect and may not be exercised.

11.Entire Agreement: Governing Law. The Notice, the Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and the Grantee with respect to the subject matter hereof, and may not be modified adversely to the Grantee’s interest except by means of a writing signed by the Company and the Grantee. Nothing in the Notice, the Plan or this Option Agreement (except as expressly provided therein) is intended to confer any rights or remedies on any persons other than the parties. The Notice, the Plan and this Option Agreement are to be construed in accordance with and

governed by the internal laws of the State of California without giving effect to any choice of law rule that would cause the application of the laws of any jurisdiction other than the internal laws of the State of California to the rights and duties of the parties. Should any provision of the Notice, the Plan or this Option Agreement be determined to be illegal or unenforceable, such provision shall be enforced to the fullest extent allowed by law and the other provisions shall nevertheless remain effective and shall remain enforceable.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Basis of Presentation

Organization and Basis of Presentation

The accompanying unaudited condensed consolidated financial statements present the accounts of Essex Property Trust, Inc. (“Essex” or the “Company”), which include the accounts of the Company and Essex Portfolio, L.P. and its subsidiaries (the “Operating Partnership,” which holds the operating assets of the Company), prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q. In the opinion of management, all adjustments necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented have been included and are normal and recurring in nature. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2017.

All significant intercompany accounts and transactions have been eliminated in the unaudited condensed consolidated financial statements. Certain reclassifications have been made to conform to the current year’s presentation, including the reclassification of corporate-level property management expenses out of property operating, excluding real estate taxes to its own line item on the Company's condensed consolidated statements of income and comprehensive income. Additionally, $10.0 million and $9.3 million has been reclassified out of other assets and into building and improvements on the Company's condensed consolidated balance sheets as of June 30, 2018 and December 31, 2017, respectively.

The unaudited condensed consolidated financial statements for the three and six months ended June 30, 2018 and 2017 include the accounts of the Company and the Operating Partnership. Essex is the sole general partner of the Operating Partnership, with a 96.7% general partnership interest as of both June 30, 2018 and December 31, 2017. Total Operating Partnership limited partnership units (“OP Units,” and the holders of such OP Units, “Unitholders”) outstanding were 2,272,983 and 2,268,114 as of June 30, 2018 and December 31, 2017, respectively, and the redemption value of the units, based on the closing price of the Company’s common stock totaled approximately $543.4 million and $547.5 million as of June 30, 2018 and December 31, 2017, respectively.

As of June 30, 2018, the Company owned or had ownership interests in 247 operating apartment communities, comprising 59,982 apartment homes, excluding the Company’s ownership in preferred equity interest co-investments, one operating commercial building, six active developments and three loan investments. The operating apartment communities are located in Southern California (Los Angeles, Orange, San Diego, and Ventura counties), Northern California (the San Francisco Bay Area) and the Seattle metropolitan areas.

Accounting Pronouncements Adopted in the Current Year

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09 “Revenue from Contracts with Customers.” The new standard provides a single comprehensive revenue recognition model for contracts with customers (excluding certain contracts, such as lease contracts) to improve comparability within industries. The new standard requires an entity to recognize revenue to reflect the transfer of goods or services to customers at an amount the entity expects to be paid in exchange for those goods and services and provide enhanced disclosures, all to provide more comprehensive guidance for transactions such as service revenue and contract modifications. The new standard is effective for interim and annual periods beginning after December 15, 2017. The new standard may be applied using either a full retrospective or a modified approach upon adoption. The Company adopted ASU No. 2014-09 as of January 1, 2018 using the modified retrospective approach. See Note 3, Revenues, for further details.

In January 2016, the FASB issued ASU No. 2016-01 “Recognition and Measurement of Financial Assets and Financial Liabilities,” which requires changes to the classification and measurement of investments in certain equity securities and to the presentation of certain fair value changes for financial liabilities measured at fair value. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2016-01 as of January 1, 2018 using the modified retrospective method by applying a cumulative effect adjustment to retained earnings and partners' capital of $2.2 million, representing accumulated net unrealized gains of certain equity securities held by the Company. Furthermore, as a result of the adoption of this standard, the Company will recognize changes in the fair value of equity investments with readily determinable fair values through net income as opposed to comprehensive income.

In August 2016, the FASB issued ASU No. 2016-15 “Classification of Certain Cash Receipts and Cash Payments,” which requires entities to adhere to a uniform classification and presentation of certain cash receipts and cash payments in the statement of cash flows. The amendments in this update provide guidance on eight specific cash flow issues. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2016-15 as of January 1, 2018 using the retrospective transition method. This amendment did not have a material impact on the Company's consolidated results of operations or financial position.

In November 2016, the FASB issued ASU No. 2016-18 “Statement of Cash Flows,” which requires entities to include restricted cash and restricted cash equivalents in the reconciliation of beginning-of-period to the end-of-period of cash and cash equivalents in the statement of cash flows. This new standard seeks to eliminate the current diversity in practice in how changes in restricted cash and restricted cash equivalents is presented in the statement of cash flows. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2016-18 as of January 1, 2018 using the retrospective transition method. This amendment did not have a material impact on the Company's consolidated results of operations or financial position.

In January 2017, the FASB issued ASU No. 2017-01 “Business Combinations: Clarifying the Definition of a Business,” which provides a new framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Previously, U.S. GAAP did not specify the minimum inputs and processes required for an integrated set of assets and activities to meet the definition of a business, causing a broad interpretation of the definition of a business. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2017-01 as of January 1, 2018 prospectively. The Company expects that substantially all of its acquisitions of communities will qualify as asset acquisitions and transaction costs related to these acquisitions will be capitalized upon adoption.

In February 2017, the FASB issued ASU No. 2017-05 “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets,” which adds guidance for partial sales of nonfinancial assets, including partial sales of real estate. Historically, U.S. GAAP contained several different accounting models to evaluate whether the transfer of certain assets qualified for sale treatment. This new standard reduces the number of potential accounting models that might apply and clarifies which model does apply in various circumstances. Partial sales of nonfinancial assets are common in the real estate industry and include transactions in which the seller retains an equity interest in the entity that owns the assets or has an equity interest in the buyer. The new standard is effective for interim and annual periods beginning after December 15, 2017. Management performed an evaluation of all of the Company's contracts that may be affected by the new standard. The Company adopted ASU No. 2017-05 concurrently with the adoption of ASU No. 2014-09 “Revenue from Contracts with Customers” as of January 1, 2018 using the modified-retrospective method by applying a cumulative effect adjustment to retained earnings and partners' capital of $123.7 million, representing the partial sale of its membership interest in BEX II, LLC (“BEX II”) during the fourth quarter of 2016.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02 “Leases,” which requires an entity that is a lessee to classify leases as either finance or operating and to recognize a lease liability and a right-of-use asset for all leases that have a duration of greater than 12 months. Leases of 12 months or less will be accounted for similar to existing guidance for operating leases today. For lessors, accounting for leases under the new standard will be substantially the same as existing guidance for sales-type leases, direct financing leases, and operating leases, but eliminates current real estate specific provisions and changes the treatment of initial direct costs. The new standard will be effective for the Company beginning on January 1, 2019 and early adoption is permitted, including adoption in an interim period. The Company currently anticipates adopting the new standard on the effective date. The Company expects that its residential and commercial leases, where it is the lessor, will continue to be accounted for as operating leases under the new standard. As a result, the Company does not currently expect significant changes in the accounting for its lease revenues. For leases where the Company is the lessee, which includes various corporate office and ground leases, the Company will be required to recognize a right of use asset and related lease liability on its consolidated balance sheets upon adoption. The Company expects that its corporate office leases, where it is the lessee, will continue to be accounted for as operating leases. The Company also expects to elect a package of practical expedients, under which the Company would not be required to reassess the classification of existing ground leases. The Company is continuing to evaluate the impact of this amendment on its consolidated results of operations and financial position.

In June 2016, the FASB issued ASU No. 2016-13 “Measurement of Credit Losses on Financial Instruments,” which amends the current approach to estimate credit losses on certain financial assets, including trade and other receivables, available-for-sale securities, and other financial instruments. Generally, this amendment requires entities to establish a valuation allowance for the expected lifetime losses of these certain financial assets. Subsequent changes in the valuation allowance are recorded in current earnings and reversal of previous losses are permitted. Currently, U.S. GAAP requires entities to write down credit losses only when losses are probable and loss reversals are not permitted. The new standard will be effective for the Company beginning on January 1, 2020 and early adoption is permitted. The Company is currently evaluating the impact of this amendment on its consolidated results of operations and financial position.

In August 2017, the FASB issued ASU No. 2017-12 “Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities,” which, among other things, requires entities to present the earnings effect of hedging instruments in the same income statement line item in which the earnings effect of the hedged item is reported. The new standard also adds new disclosure requirements. This new standard will be effective for the Company beginning January 1, 2019 and early adoption is permitted. The Company is currently evaluating the impact of this amendment on its consolidated results of operations and financial position.

Marketable Securities

The Company reports its equity securities and available for sale debt securities at fair value, based on quoted market prices (Level 1 for the common stock and investment funds, Level 2 for the unsecured bonds and Level 3 for investments in mortgage backed securities, as defined by the FASB standard for fair value measurements). Any unrealized gain or loss in debt securities classified as available for sale is recorded as other comprehensive income. Unrealized gains and losses in equity securities, realized gains and losses in debt securities, interest income, and amortization of purchase discounts are included in interest and other income on the condensed consolidated statements of income and comprehensive income.

As of June 30, 2018 and December 31, 2017, equity securities and available for sale debt securities consisted primarily of investment-grade unsecured bonds, common stock and stock funds, investments in mortgage backed securities, and investment funds that invest in U.S. treasury or agency securities. As of June 30, 2018 and December 31, 2017, the Company classified its investments in mortgage backed securities, which mature in November 2019 and September 2020, as held to maturity, and accordingly, these securities are stated at their amortized cost. The discount on the mortgage backed securities is being amortized to interest income based on an estimated yield and the maturity date of the securities.

As of June 30, 2018 and December 31, 2017, marketable securities consist of the following ($ in thousands):

	June 30, 2018

The Company uses the specific identification method to determine the cost basis of a debt security sold and to reclassify amounts from accumulated other comprehensive income for such securities. 

For the three months ended June 30, 2018 and 2017, the proceeds from sales and maturities of marketable securities totaled $9.4 million and $3.9 million, respectively, which resulted in $0.2 million in realized loss and $13,000 in realized gains, respectively, for such periods. For the six months ended June 30, 2018 and 2017, the proceeds from sales and maturities of marketable securities totaled $19.0 million and $28.8 million, respectively, which resulted in $0.5 million and $1.6 million in realized gains, respectively, for such periods.

For the three and six months ended June 30, 2018, the portion of equity security unrealized gains and losses that were recognized in income totaled $0.1 million in unrecognized gains and $0.8 million in unrealized losses and is included in interest and other income on the Company's condensed consolidated statements of income and comprehensive income.

Variable Interest Entities

In accordance with accounting standards for consolidation of variable interest entities (“VIEs”), the Company consolidates the Operating Partnership, 16 limited partnerships, comprising eight communities, (the “DownREIT limited partnerships,”) and eight co-investments as of June 30, 2018. The Company consolidates these entities because it is deemed the primary beneficiary. The Company has no assets or liabilities other than its investment in the Operating Partnership. The consolidated total assets and liabilities related to the eight consolidated co-investments and 16 DownREIT limited partnerships, net of intercompany eliminations, were approximately $835.2 million and $262.9 million, respectively, as of June 30, 2018 and $837.7 million and $265.5 million, respectively, as of December 31, 2017. Noncontrolling interests in these entities were $64.9 million and $66.7 million as of June 30, 2018 and December 31, 2017, respectively. The Company's financial risk in each VIE is limited to its equity investment in the VIE. As of June 30, 2018 and December 31, 2017, the Company did not have any other VIEs of which it was deemed to be the primary beneficiary and did not have any VIEs of which it was not deemed to be the primary beneficiary.

Equity-based Compensation

The cost of share- and unit-based compensation awards is measured at the grant date based on the estimated fair value of the awards. The estimated fair value of stock options and restricted stock granted by the Company are being amortized over the vesting period. The estimated grant date fair values of the long term incentive plan units (discussed in Note 12, “Equity Based Compensation Plans,” in the Company’s annual report on Form 10-K for the year ended December 31, 2017) are being amortized over the expected service periods.

Fair Value of Financial Instruments

Management believes that the carrying amounts of the outstanding balances under its lines of credit, and notes and other receivables approximate fair value as of June 30, 2018 and December 31, 2017, because interest rates, yields, and other terms for these instruments are consistent with yields and other terms currently available for similar instruments. Management has estimated that the fair value of the Company’s fixed rate debt with a carrying value of $5.1 billion and $4.9 billion, including premiums, discounts and debt financing costs, at June 30, 2018 and December 31, 2017, respectively, was approximately $5.1 billion and $5.0 billion. Management has estimated that the fair value of the Company’s $615.1 million and $792.9 million of variable rate debt, net of debt financing costs, at June 30, 2018 and December 31, 2017, respectively, was approximately $618.2 million and $793.9 million based on the terms of existing mortgage notes payable, unsecured debt, and variable rate demand notes compared to those available in the marketplace. Management believes that the carrying amounts of cash and cash equivalents, restricted cash, accounts payable and accrued liabilities, construction payables, other liabilities, and dividends payable approximate fair value as of June 30, 2018 and December 31, 2017 due to the short-term maturity of these instruments. Marketable securities, except mortgage backed securities, and derivatives are carried at fair value as of June 30, 2018 and December 31, 2017.

At June 30, 2018, the Company’s investments in mortgage backed securities had a carrying value of $118.0 million and the Company estimated the fair value to be approximately $127.2 million. At December 31, 2017, the Company’s investments in mortgage backed securities had a carrying value of $109.5 million and the Company estimated the fair value to be approximately $120.7 million. The Company determines the fair value of the mortgage backed securities based on unobservable inputs (level 3 of the fair value hierarchy) considering the assumptions that market participants would make in valuing these securities. Assumptions such as estimated default rates and discount rates are used to determine the expected discounted cash flows to estimate fair value.

Capitalization of Costs

The Company’s capitalized internal costs related to development and redevelopment projects were comprised primarily of employee compensation and totaled $4.5 million and $4.6 million during the three months ended June 30, 2018 and 2017, respectively, and $9.5 million and $9.4 million for the six months ended June 30, 2018 and 2017, respectively. The Company capitalizes leasing commissions associated with the lease-up of development communities and amortizes the costs over the life of the leases. The amounts capitalized for leasing commissions are immaterial for all periods presented.

Co-investments

The Company owns investments in joint ventures (“co-investments”) in which it has significant influence, but its ownership interest does not meet the criteria for consolidation in accordance with U.S. GAAP. Therefore, the Company accounts for co-investments using the equity method of accounting. Under the equity method of accounting, the investment is carried at the cost of assets contributed, plus the Company's equity in earnings less distributions received and the Company's share of losses. The significant accounting policies of the Company’s co-investment entities are consistent with those of the Company in all material respects.

Upon the acquisition of a controlling interest of a co-investment, the co-investment entity is consolidated and the transaction will be accounted for as a business combination if the entity meets the definition of a business pursuant to ASU No. 2017-01, or an asset acquisition if the entity is not determined to be a business. A majority of the co-investments, excluding the preferred equity investments, compensate the Company for its asset management services and some of these investments may provide promote income if certain financial return benchmarks are achieved. Asset management fees are recognized when earned, and promote fees are recognized when the earnings events have occurred and the amount is determinable and collectible. Any promote fees are reflected in equity income from co-investments.

The Company reports investments in co-investments where accumulated distributions have exceeded the Company’s investment as distributions in excess of investments in co-investments in the accompanying condensed consolidated balance sheets. As of December 31, 2017, the net investment of one of the Company’s co-investments was less than zero as a result of financing distributions in excess of the Company's investment in that co-investment. As a result of the Company's adoption of ASU No. 2017-05 on January 1, 2018, the carrying value of this co-investment was greater than zero as of June 30, 2018.

Accounting Estimates

The preparation of condensed consolidated financial statements, in accordance with U.S. GAAP, requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to acquiring, developing and assessing the carrying values of its real estate portfolio, its investments in and advances to joint ventures and affiliates, its notes receivables, and its qualification as a real estate investment trust (“REIT”). The Company bases its estimates on historical experience, current market conditions, and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may vary from those estimates and those estimates could be different under different assumptions or conditions.

Revenue from Contract with Customer [Abstract]

Revenues

Revenues

On January 1, 2018, the Company adopted ASU 2014-09, “Revenue from Contracts with Customers” using a modified retrospective transition method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods after January 1, 2018 are presented under the new standard, while prior period amounts are not adjusted and continue to be reported in accordance with the old revenue recognition standard.

Based on a full analysis of applicable contracts, the Company determined that the new standard did not have an impact to reported revenues from prior or current periods.

Revenue Recognition

Revenue from Leasing

The Company generates revenues primarily from leasing apartment homes to tenants. Such leasing revenues are recorded when due from tenants and are recognized monthly as they are earned, which is not materially different than on a straight-line basis. Apartment homes are rented under short-term leases (generally, lease terms of 6 to 12 months). Revenues from tenants leasing commercial space are recorded on a straight-line basis over the life of the respective lease.

The Company also generates other property-related revenue through the leasing of apartment homes, including storage income, pet rent, and other miscellaneous revenue. Similar to rental income, such revenues are recorded when due from tenants and recognized monthly as they are earned.

Revenue from Contracts with Customers

Apart from rental and other property-related revenue, revenues from contracts with customers are recognized as control of the promised services is passed to the customer.

For customer contracts related to management and other fees from affiliates (which includes asset management and property management), the transaction price and amount of revenue to be recognized is determined each quarter based on the management fee calculated and earned for that month or quarter. The contract will contain a description of the service and the fee percentage for management services. Payments from such services are one month or one quarter in arrears of the service performed.

In November 2017, the Company provided a $29.5 million related party bridge loan to a property acquired by BEX III. The note receivable accrued interest at 3.5% and was paid off in January 2018. The bridge loan was classified within notes and other receivables in the accompanying condensed consolidated balance sheets and had no amount outstanding as of June 30, 2018.

The Company’s Chairman and founder, Mr. George M. Marcus, is the Chairman of the Marcus & Millichap Company (“MMC”), which is a parent company of a diversified group of real estate service, investment, and development firms. Mr. Marcus is also the Co-Chairman of Marcus & Millichap, Inc. (“MMI”), and Mr. Marcus owns a controlling interest in MMI, a national brokerage firm listed on the New York Stock Exchange. 

In May 2018, the Company made a commitment to fund a $26.5 million preferred equity investment in an entity whose sponsors include an MMC affiliated company. The entity wholly owns a 400 apartment home community located in Ventura, CA. This investment will accrue interest based on a 10.25% preferred return. The investment is scheduled to mature in May 2023. As of June 30, 2018, the Company had funded $20.4 million of the commitment. The remaining committed amount will be funded if and when requested by the sponsors.

In March 2017, the Company converted its existing $15.3 million preferred equity investment in Sage at Cupertino, a 230 apartment home community located in San Jose, CA, into a 40.5% common equity ownership interest in the property. The Company issued DownREIT units to the other members, including an MMC affiliate, based on an estimated property valuation of $90.0 million. At the time of the conversion, the property was encumbered by $52.0 million of mortgage debt. As a result of this transaction, the Company consolidates the property, based on a VIE analysis performed by the Company.

In 2015, the Company made preferred equity investments totaling $20.0 million in three entities affiliated with MMC that own apartment communities in California. The Company earns a 9.5% preferred return on each such investment. One $5.0 million investment, which was scheduled to mature in 2022, was fully redeemed in 2017. The remaining two investments are scheduled to mature in 2022.

Segment Information

Segment Information

The Company's segment disclosures present the measure used by the chief operating decision makers for purposes of assessing each segment's performance. The Company's chief operating decision makers are comprised of several members of its executive management team who use net operating income (“NOI”) to assess the performance of the business for the Company's reportable operating segments. NOI represents total property revenue less direct property operating expenses.

The executive management team evaluates the Company's operating performance geographically. The Company defines its reportable operating segments as the three geographical regions in which its communities are located: Southern California, Northern California, and Seattle Metro.

Excluded from segment revenues and NOI are management and other fees from affiliates and interest and other income. Non-segment revenues and NOI included in the following schedule also consist of revenue generated from commercial properties and properties that have been sold. Other non-segment assets include items such as real estate under development, co-investments, real estate held for sale, net, cash and cash equivalents, marketable securities, notes and other receivables, and prepaid expenses and other assets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities

Derivative Instruments and Hedging Activities

As of June 30, 2018, the Company had entered into interest rate swap contracts with an aggregate notional amount of $175.0 million that effectively fixed the interest rate on the $175.0 million unsecured term loan at 2.3%. These derivatives qualify for hedge accounting.

As of June 30, 2018, the Company had interest rate caps, which are not accounted for as hedges, totaling a notional amount of $9.9 million that effectively limit the Company’s exposure to interest rate risk by providing a ceiling on the underlying variable interest rate for $9.9 million of the Company’s tax exempt variable rate debt.

As of June 30, 2018 and December 31, 2017, the aggregate carrying value of the interest rate swap contracts was an asset of $8.5 million and $5.4 million, respectively, and is included in prepaid expenses and other assets on the condensed consolidated balance sheets. The aggregate carrying value of the interest rate caps was zero on the condensed consolidated balance sheets as of both June 30, 2018 and December 31, 2017.

Hedge ineffectiveness related to cash flow hedges, which is included in interest expense on the condensed consolidated statements of income and comprehensive income, was not significant for the three and six months ended June 30, 2018 and 2017.

Additionally, the Company has entered into total return swaps that effectively convert $256.3 million of mortgage notes payable to a floating interest rate based on the Securities Industry and Financial Markets Association Municipal Swap Index (“SIFMA”) plus a spread. The total return swaps provide fair market value protection on the mortgage notes payable to the counterparties during the initial period of the total return swap until the Company's option to call the mortgage notes at par can be exercised. The Company can currently call all total return swaps, with $256.3 million of the outstanding debt at par. These derivatives do not qualify for hedge accounting and had a carrying and fair value of zero at both June 30, 2018 and December 31, 2017. These total return swaps are scheduled to mature between September 2021 and November 2022.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Consolidation Policy

The accompanying unaudited condensed consolidated financial statements present the accounts of Essex Property Trust, Inc. (“Essex” or the “Company”), which include the accounts of the Company and Essex Portfolio, L.P. and its subsidiaries (the “Operating Partnership,” which holds the operating assets of the Company), prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q. In the opinion of management, all adjustments necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented have been included and are normal and recurring in nature. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2017.

All significant intercompany accounts and transactions have been eliminated in the unaudited condensed consolidated financial statements. Certain reclassifications have been made to conform to the current year’s presentation, including the reclassification of corporate-level property management expenses out of property operating, excluding real estate taxes to its own line item on the Company's condensed consolidated statements of income and comprehensive income.

Accounting Pronouncement Adopted in the Current Year and Recent Accounting Pronouncements

Accounting Pronouncements Adopted in the Current Year

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09 “Revenue from Contracts with Customers.” The new standard provides a single comprehensive revenue recognition model for contracts with customers (excluding certain contracts, such as lease contracts) to improve comparability within industries. The new standard requires an entity to recognize revenue to reflect the transfer of goods or services to customers at an amount the entity expects to be paid in exchange for those goods and services and provide enhanced disclosures, all to provide more comprehensive guidance for transactions such as service revenue and contract modifications. The new standard is effective for interim and annual periods beginning after December 15, 2017. The new standard may be applied using either a full retrospective or a modified approach upon adoption. The Company adopted ASU No. 2014-09 as of January 1, 2018 using the modified retrospective approach. See Note 3, Revenues, for further details.

In January 2016, the FASB issued ASU No. 2016-01 “Recognition and Measurement of Financial Assets and Financial Liabilities,” which requires changes to the classification and measurement of investments in certain equity securities and to the presentation of certain fair value changes for financial liabilities measured at fair value. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2016-01 as of January 1, 2018 using the modified retrospective method by applying a cumulative effect adjustment to retained earnings and partners' capital of $2.2 million, representing accumulated net unrealized gains of certain equity securities held by the Company. Furthermore, as a result of the adoption of this standard, the Company will recognize changes in the fair value of equity investments with readily determinable fair values through net income as opposed to comprehensive income.

In August 2016, the FASB issued ASU No. 2016-15 “Classification of Certain Cash Receipts and Cash Payments,” which requires entities to adhere to a uniform classification and presentation of certain cash receipts and cash payments in the statement of cash flows. The amendments in this update provide guidance on eight specific cash flow issues. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2016-15 as of January 1, 2018 using the retrospective transition method. This amendment did not have a material impact on the Company's consolidated results of operations or financial position.

In November 2016, the FASB issued ASU No. 2016-18 “Statement of Cash Flows,” which requires entities to include restricted cash and restricted cash equivalents in the reconciliation of beginning-of-period to the end-of-period of cash and cash equivalents in the statement of cash flows. This new standard seeks to eliminate the current diversity in practice in how changes in restricted cash and restricted cash equivalents is presented in the statement of cash flows. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2016-18 as of January 1, 2018 using the retrospective transition method. This amendment did not have a material impact on the Company's consolidated results of operations or financial position.

In January 2017, the FASB issued ASU No. 2017-01 “Business Combinations: Clarifying the Definition of a Business,” which provides a new framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Previously, U.S. GAAP did not specify the minimum inputs and processes required for an integrated set of assets and activities to meet the definition of a business, causing a broad interpretation of the definition of a business. The new standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU No. 2017-01 as of January 1, 2018 prospectively. The Company expects that substantially all of its acquisitions of communities will qualify as asset acquisitions and transaction costs related to these acquisitions will be capitalized upon adoption.

In February 2017, the FASB issued ASU No. 2017-05 “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets,” which adds guidance for partial sales of nonfinancial assets, including partial sales of real estate. Historically, U.S. GAAP contained several different accounting models to evaluate whether the transfer of certain assets qualified for sale treatment. This new standard reduces the number of potential accounting models that might apply and clarifies which model does apply in various circumstances. Partial sales of nonfinancial assets are common in the real estate industry and include transactions in which the seller retains an equity interest in the entity that owns the assets or has an equity interest in the buyer. The new standard is effective for interim and annual periods beginning after December 15, 2017. Management performed an evaluation of all of the Company's contracts that may be affected by the new standard. The Company adopted ASU No. 2017-05 concurrently with the adoption of ASU No. 2014-09 “Revenue from Contracts with Customers” as of January 1, 2018 using the modified-retrospective method by applying a cumulative effect adjustment to retained earnings and partners' capital of $123.7 million, representing the partial sale of its membership interest in BEX II, LLC (“BEX II”) during the fourth quarter of 2016.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02 “Leases,” which requires an entity that is a lessee to classify leases as either finance or operating and to recognize a lease liability and a right-of-use asset for all leases that have a duration of greater than 12 months. Leases of 12 months or less will be accounted for similar to existing guidance for operating leases today. For lessors, accounting for leases under the new standard will be substantially the same as existing guidance for sales-type leases, direct financing leases, and operating leases, but eliminates current real estate specific provisions and changes the treatment of initial direct costs. The new standard will be effective for the Company beginning on January 1, 2019 and early adoption is permitted, including adoption in an interim period. The Company currently anticipates adopting the new standard on the effective date. The Company expects that its residential and commercial leases, where it is the lessor, will continue to be accounted for as operating leases under the new standard. As a result, the Company does not currently expect significant changes in the accounting for its lease revenues. For leases where the Company is the lessee, which includes various corporate office and ground leases, the Company will be required to recognize a right of use asset and related lease liability on its consolidated balance sheets upon adoption. The Company expects that its corporate office leases, where it is the lessee, will continue to be accounted for as operating leases. The Company also expects to elect a package of practical expedients, under which the Company would not be required to reassess the classification of existing ground leases. The Company is continuing to evaluate the impact of this amendment on its consolidated results of operations and financial position.

In June 2016, the FASB issued ASU No. 2016-13 “Measurement of Credit Losses on Financial Instruments,” which amends the current approach to estimate credit losses on certain financial assets, including trade and other receivables, available-for-sale securities, and other financial instruments. Generally, this amendment requires entities to establish a valuation allowance for the expected lifetime losses of these certain financial assets. Subsequent changes in the valuation allowance are recorded in current earnings and reversal of previous losses are permitted. Currently, U.S. GAAP requires entities to write down credit losses only when losses are probable and loss reversals are not permitted. The new standard will be effective for the Company beginning on January 1, 2020 and early adoption is permitted. The Company is currently evaluating the impact of this amendment on its consolidated results of operations and financial position.

In August 2017, the FASB issued ASU No. 2017-12 “Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities,” which, among other things, requires entities to present the earnings effect of hedging instruments in the same income statement line item in which the earnings effect of the hedged item is reported. The new standard also adds new disclosure requirements. This new standard will be effective for the Company beginning January 1, 2019 and early adoption is permitted. The Company is currently evaluating the impact of this amendment on its consolidated results of operations and financial position.

Marketable Securities

Marketable Securities

The Company reports its equity securities and available for sale debt securities at fair value, based on quoted market prices (Level 1 for the common stock and investment funds, Level 2 for the unsecured bonds and Level 3 for investments in mortgage backed securities, as defined by the FASB standard for fair value measurements). Any unrealized gain or loss in debt securities classified as available for sale is recorded as other comprehensive income. Unrealized gains and losses in equity securities, realized gains and losses in debt securities, interest income, and amortization of purchase discounts are included in interest and other income on the condensed consolidated statements of income and comprehensive income.

As of June 30, 2018 and December 31, 2017, equity securities and available for sale debt securities consisted primarily of investment-grade unsecured bonds, common stock and stock funds, investments in mortgage backed securities, and investment funds that invest in U.S. treasury or agency securities. As of June 30, 2018 and December 31, 2017, the Company classified its investments in mortgage backed securities, which mature in November 2019 and September 2020, as held to maturity, and accordingly, these securities are stated at their amortized cost. The discount on the mortgage backed securities is being amortized to interest income based on an estimated yield and the maturity date of the securities.

Variable Interest Entities

Variable Interest Entities

In accordance with accounting standards for consolidation of variable interest entities (“VIEs”), the Company consolidates the Operating Partnership, 16 limited partnerships, comprising eight communities, (the “DownREIT limited partnerships,”) and eight co-investments as of June 30, 2018. The Company consolidates these entities because it is deemed the primary beneficiary. The Company has no assets or liabilities other than its investment in the Operating Partnership. The consolidated total assets and liabilities related to the eight consolidated co-investments and 16 DownREIT limited partnerships, net of intercompany eliminations, were approximately $835.2 million and $262.9 million, respectively, as of June 30, 2018 and $837.7 million and $265.5 million, respectively, as of December 31, 2017. Noncontrolling interests in these entities were $64.9 million and $66.7 million as of June 30, 2018 and December 31, 2017, respectively. The Company's financial risk in each VIE is limited to its equity investment in the VIE. As of June 30, 2018 and December 31, 2017, the Company did not have any other VIEs of which it was deemed to be the primary beneficiary and did not have any VIEs of which it was not deemed to be the primary beneficiary.

Equity-based Compensation

Equity-based Compensation

The cost of share- and unit-based compensation awards is measured at the grant date based on the estimated fair value of the awards. The estimated fair value of stock options and restricted stock granted by the Company are being amortized over the vesting period. The estimated grant date fair values of the long term incentive plan units (discussed in Note 12, “Equity Based Compensation Plans,” in the Company’s annual report on Form 10-K for the year ended December 31, 2017) are being amortized over the expected service periods.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Management believes that the carrying amounts of the outstanding balances under its lines of credit, and notes and other receivables approximate fair value as of June 30, 2018 and December 31, 2017, because interest rates, yields, and other terms for these instruments are consistent with yields and other terms currently available for similar instruments. Management has estimated that the fair value of the Company’s fixed rate debt with a carrying value of $5.1 billion and $4.9 billion, including premiums, discounts and debt financing costs, at June 30, 2018 and December 31, 2017, respectively, was approximately $5.1 billion and $5.0 billion. Management has estimated that the fair value of the Company’s $615.1 million and $792.9 million of variable rate debt, net of debt financing costs, at June 30, 2018 and December 31, 2017, respectively, was approximately $618.2 million and $793.9 million based on the terms of existing mortgage notes payable, unsecured debt, and variable rate demand notes compared to those available in the marketplace. Management believes that the carrying amounts of cash and cash equivalents, restricted cash, accounts payable and accrued liabilities, construction payables, other liabilities, and dividends payable approximate fair value as of June 30, 2018 and December 31, 2017 due to the short-term maturity of these instruments. Marketable securities, except mortgage backed securities, and derivatives are carried at fair value as of June 30, 2018 and December 31, 2017.

At June 30, 2018, the Company’s investments in mortgage backed securities had a carrying value of $118.0 million and the Company estimated the fair value to be approximately $127.2 million. At December 31, 2017, the Company’s investments in mortgage backed securities had a carrying value of $109.5 million and the Company estimated the fair value to be approximately $120.7 million. The Company determines the fair value of the mortgage backed securities based on unobservable inputs (level 3 of the fair value hierarchy) considering the assumptions that market participants would make in valuing these securities. Assumptions such as estimated default rates and discount rates are used to determine the expected discounted cash flows to estimate fair value.

Capitalization of Costs

Capitalization of Costs

The Company’s capitalized internal costs related to development and redevelopment projects were comprised primarily of employee compensation and totaled $4.5 million and $4.6 million during the three months ended June 30, 2018 and 2017, respectively, and $9.5 million and $9.4 million for the six months ended June 30, 2018 and 2017, respectively. The Company capitalizes leasing commissions associated with the lease-up of development communities and amortizes the costs over the life of the leases. The amounts capitalized for leasing commissions are immaterial for all periods presented.

Co-investments

Co-investments

The Company owns investments in joint ventures (“co-investments”) in which it has significant influence, but its ownership interest does not meet the criteria for consolidation in accordance with U.S. GAAP. Therefore, the Company accounts for co-investments using the equity method of accounting. Under the equity method of accounting, the investment is carried at the cost of assets contributed, plus the Company's equity in earnings less distributions received and the Company's share of losses. The significant accounting policies of the Company’s co-investment entities are consistent with those of the Company in all material respects.

Upon the acquisition of a controlling interest of a co-investment, the co-investment entity is consolidated and the transaction will be accounted for as a business combination if the entity meets the definition of a business pursuant to ASU No. 2017-01, or an asset acquisition if the entity is not determined to be a business. A majority of the co-investments, excluding the preferred equity investments, compensate the Company for its asset management services and some of these investments may provide promote income if certain financial return benchmarks are achieved. Asset management fees are recognized when earned, and promote fees are recognized when the earnings events have occurred and the amount is determinable and collectible. Any promote fees are reflected in equity income from co-investments.

The Company reports investments in co-investments where accumulated distributions have exceeded the Company’s investment as distributions in excess of investments in co-investments in the accompanying condensed consolidated balance sheets. As of December 31, 2017, the net investment of one of the Company’s co-investments was less than zero as a result of financing distributions in excess of the Company's investment in that co-investment. As a result of the Company's adoption of ASU No. 2017-05 on January 1, 2018, the carrying value of this co-investment was greater than zero as of June 30, 2018.

Changes in Accumulated Other Comprehensive Loss

Amounts reclassified from accumulated other comprehensive loss in connection with derivatives are recorded in interest expense on the condensed consolidated statements of income and comprehensive income. Realized gains and losses on available for sale debt securities are included in interest and other income on the condensed consolidated statements of income and comprehensive income.

Cash, Cash Equivalents and Restricted Cash

Cash, Cash Equivalents and Restricted Cash

Highly liquid investments with original maturities of three months or less when purchased are classified as cash equivalents. Restricted cash balances relate primarily to reserve requirements for capital replacement at certain communities in connection with the Company’s mortgage debt.

Accounting Estimates

Accounting Estimates

The preparation of condensed consolidated financial statements, in accordance with U.S. GAAP, requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to acquiring, developing and assessing the carrying values of its real estate portfolio, its investments in and advances to joint ventures and affiliates, its notes receivables, and its qualification as a real estate investment trust (“REIT”). The Company bases its estimates on historical experience, current market conditions, and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may vary from those estimates and those estimates could be different under different assumptions or conditions.
