Principles of Consolidation and Basis of Presentation

The accounts of the Company, its controlled subsidiaries and the variable interest entities (“VIEs”) in which it is the primary beneficiary are consolidated in the accompanying financial statements and prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). 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. All significant inter-company accounts and transactions have been eliminated. Certain reclassifications have been made to prior year amounts to conform to the current year’s presentation. Such reclassifications had no net effect on previously reported financial results.

Noncontrolling interest includes the 3.3% limited partner interests in the Operating Partnership not held by the Company at both December 31, 2015 and 2014. These percentages include the Operating Partnership’s vested long term incentive plan units (see Note 13).

The Company consolidates the Operating Partnership and 19 DownREIT limited partnerships (comprising eleven communities), since the Company is the primary beneficiary of these variable interest entities (“VIEs”). The Company has no assets or liabilities other than its investment in the Operating Partnership. The consolidated total assets and liabilities related to these DownREIT VIEs, net of intercompany eliminations, were approximately $241.0 million and $206.7 million, respectively, as of December 31, 2015, and $235.1 million and $209.1 million, respectively, as of December 31, 2014.

The DownREIT VIEs collectively own eleven apartment communities in which Essex Management Company (“EMC”) is the general partner, the Operating Partnership is a special limited partner, and the other limited partners were granted rights of redemption for their interests. Such limited partners can request to be redeemed and the Company, subject to certain restrictions, can elect to redeem their rights for cash or by issuing shares of its common stock on a one share per unit basis. Conversion values will be based on the market value of the Company's common stock at the time of redemption multiplied by the number of units stipulated under the above arrangements. The other limited partners receive distributions based on the Company's current dividend rate times the number of units held. Total DownREIT units outstanding were 963,172 and 974,790 as of December 31, 2015 and 2014 respectively, and the redemption value of the units, based on the closing price of the Company’s common stock totaled approximately $230.6 million and $201.4 million, as of December 31, 2015 and 2014, respectively. The carrying value of redeemable noncontrolling interest in the accompanying balance sheets was $45.5 million and $23.3 million as of December 31, 2015 and 2014, respectively. The amounts represent units of limited partners' interests in DownREIT VIEs as to which it is outside of the Company’s control to redeem the DownREIT units with Company common stock and may potentially be redeemed for cash, and are presented at either their redemption value or historical cost, depending on the limited partner's right to redeem their units as of the balance sheet date. The carrying value of DownREIT units as to which it is within the control of the Company to redeem the units with its common stock is $18.4 million and $30.8 million as of December 31, 2015 and 2014, respectively and is classified within noncontrolling interests in the accompanying consolidated balance sheets.

Interest holders in VIEs consolidated by the Company are allocated a priority of net income equal to the cash payments made to those interest holders or distributions from cash flow. The remaining results of operations are generally allocated to the Company.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU 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. In August 2015, the FASB deferred the effective date of the new standard by one year, and it is now effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted but not before the original effective date. The new standard may be applied using either a full retrospective or a modified approach upon adoption. The Company has not yet selected a transition method and is currently evaluating the impact of adopting the new standard on its consolidated results of operations and financial position.

In February 2015, the FASB issued ASU No. 2015-02 "Consolidation (Topic 810): Amendments to the Consolidation Analysis", which provides new consolidation guidance and makes changes to both the variable interest model and the voting model. Among other changes, the new standard specifically eliminates the presumption in the current voting model that a general partner controls a limited partnership or similar entity unless that presumption can be overcome. Generally, only a single limited partner that is able to exercise substantive kick-out rights will consolidate. The new standard will be effective for the Company beginning on January 1, 2016 and early adoption is permitted, including adoption in an interim period. The new standard must be applied using a modified retrospective approach by recording a cumulative-effect adjustment to equity/capital as of the beginning of the period of adoption or retrospectively to each period presented. The Company is currently evaluating the impact of adopting the new standard on its consolidated results of operations and financial position.

In April 2015, the FASB issued ASU No. 2015-03 "Simplifying the Presentation of Debt Issuance Costs", which requires companies to present debt financing costs as a direct deduction from the carrying amount of the associated debt liability rather than as an asset, consistent with the presentation of debt discounts on the consolidated balance sheets. The new standard will be effective for the Company beginning on January 1, 2016 and early adoption is permitted. The Company adopted this standard during the second quarter of 2015. This adoption resulted in a reclassification of $29.4 million in debt issuance costs, net of accumulated amortization, from an asset to a reduction to associated debt liabilities as of December 31, 2014.

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 will be effective for the Company beginning on January 1, 2018 and early adoption is permitted. The Company is currently evaluating the impact of this amendment on its consolidated results of operations and financial position.

Real Estate Rental Properties

Significant expenditures, which improve or extend the life of an asset and have a useful life of greater than one year, are capitalized. Operating real estate assets are stated at cost and consist of land, buildings and improvements, furniture, fixtures and equipment, and other costs incurred during their development, redevelopment and acquisition. Expenditures for maintenance and repairs are charged to expense as incurred.

The depreciable life of various categories of fixed assets is as follows:



Computer software and equipment	3 - 5 years
Interior apartment home improvements	5 years
Furniture, fixtures and equipment	5 years
Land improvements and certain exterior components of real property	10 years
Real estate structures	30 years

The Company capitalizes all costs incurred with the predevelopment, development or redevelopment of real estate assets or are associated with the construction or expansion of real property. Such capitalized costs include land, land improvements, allocated costs of the Company’s project management staff, construction costs, as well as interest and related loan fees, property taxes and insurance. Capitalization begins for predevelopment, development, and redevelopment projects when activity commences. Capitalization ends when the apartment home is completed and the property is available for a new resident or if the development activities cease.

The Company allocates the purchase price of real estate to land and building including personal property, and identifiable intangible assets, such as the value of above, below and in-place leases. The values of the above and below market leases are amortized and recorded as either a decrease (in the case of above market leases) or an increase (in the case of below market leases) to rental revenue over the remaining term of the associated leases acquired, which in the case of below market leases the Company assumes lessees will elect to renew their leases. The value of acquired in-place leases are amortized to expense over the term the Company expects to retain the acquired tenant, which is generally 15 months. The net carrying value of acquired in-place leases as of December 31, 2015 of $2.9 million is expected to be recognized in amortization expense primarily in 2016.

The Company performs the following evaluation for communities acquired:


(1)	adjust the purchase price for any fair value adjustments resulting from such things as assumed debt or contingencies;


(2)	estimate the value of the real estate “as if vacant” as of the acquisition date;


(3)	allocate that value among land and buildings including personal property;


(4)	compute the value of the difference between the “as if vacant” value and the adjusted purchase price, which will represent the total intangible assets;


(5)	compute the value of the above and below market leases and determine the associated life of the above market/ below market leases;


(6)	compute the value of the in-place leases and customer relationships, if any, and the associated lives of these assets.

Whenever events or changes in circumstances indicate that the carrying amount of a property held for investment or held for sale may not be fully recoverable, the carrying amount will be evaluated for impairment. If the sum of the expected future cash flows (undiscounted and without interest charges) is less than the carrying amount (including intangible assets) of a property held for investment, then the Company will recognize an impairment loss equal to the excess of the carrying amount over the fair value of the property. Fair value of a property is determined using conventional real estate valuation methods, such as discounted cash flow, the property’s unleveraged yield in comparison to the unleveraged yields and sales prices of similar communities that have been recently sold, and other third party information, if available. Communities held for sale are carried at the lower of cost and fair value less estimated costs to sell. As of December 31, 2015 and 2014, two and one properties were classified as held for sale, respectively. No impairment charges were recorded in 2015, 2014 or 2013.

In the normal course of business, the Company will receive purchase offers for its communities, either solicited or unsolicited. For those offers that are accepted, the prospective buyer will usually require a due diligence period before consummation of the transaction. It is not unusual for matters to arise that result in the withdrawal or rejection of the offer during this process. The Company classifies real estate as "held for sale" when all criteria under the accounting standard for the disposals of long-lived assets have been met.

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 the accounting standards. Therefore, the Company accounts for these 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.

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 distributions 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 (loss) from co-investments.

Revenues and Gains on Sale of Real Estate

Revenues from tenants renting or leasing apartment homes 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 recognizes gains on sales of real estate when a contract is in place, a closing has taken place, the buyer’s initial and continuing investment is adequate to demonstrate a commitment to pay for the property and the Company does not have a substantial continuing involvement with the property.

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.

Marketable Securities

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

The Company reports its available for sale 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 the limited partnership interests, as defined by the FASB standard for fair value measurements as discussed later in Note 2), and any unrealized gain or loss is recorded as other comprehensive income (loss).

Notes Receivable

Notes receivable relate to real estate financing arrangements including mezzanine and bridge loans and are secured by real estate. Interest is recognized over the life of the note as interest income.

Each note is analyzed to determine if it is impaired. A note is impaired if it is probable that the Company will not collect all contractually due principal and interest. The Company does not accrue interest when a note is considered impaired and an allowance is recorded for any principal and previously accrued interest that are not believed to be collectible. All cash receipts on impaired notes are applied to reduce the principal amount of such notes until the principal has been recovered and, thereafter, are recognized as interest income.

Capitalization Policy

The Company capitalizes all direct and certain indirect costs, including interest, real estate taxes and insurance, incurred during development and redevelopment activities. Interest is capitalized on real estate assets that require a period of time to get them ready for their intended use. The amount of interest capitalized is based upon the average amount of accumulated development expenditures during the reporting period. Included in capitalized costs are management’s estimates of the direct and incremental personnel costs and indirect project costs associated with the Company's development and redevelopment activities. Indirect project costs consist primarily of personnel costs associated with construction administration and development, including accounting, legal fees, and various corporate and community onsite costs that clearly relate to projects under development.

Fair Value of Financial Instruments

The Company values its financial instruments based on the fair value hierarchy of valuation techniques described in the FASB’s accounting standard for fair value measurements. Level 1 inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 inputs include quoted prices for similar assets and liabilities in active markets and inputs other than quoted prices observable for the asset or liability. Level 3 inputs are unobservable inputs for the asset or liability. The Company uses Level 1 inputs for the fair values of its cash equivalents and its marketable securities except for unsecured bonds and mortgage backed securities. The Company uses Level 2 inputs for its investments in unsecured bonds, notes receivable, notes payable, and derivative liabilities. These inputs include interest rates for similar financial instruments. The Company’s valuation methodology for derivatives is described in Note 9. The Company uses Level 3 inputs to estimate the fair value of its mortgage backed securities. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

Management believes that the carrying amounts of the outstanding balances under its notes and other receivables approximate fair value as of December 31, 2015 and 2014, 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 fixed rate debt with a carrying value of $4.8 billion and $4.4 billion, at December 31, 2015 and 2014, respectively, to be $4.8 billion and $4.6 billion. Management has estimated the fair value of the Company’s $525.3 million and $651.7 million of variable rate debt at December 31, 2015 and 2014, respectively, is $527.6 million and $656.3 million based on the terms of the Company’s existing variable rate debt 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 payable, other liabilities and dividends payable approximate fair value as of December 31, 2015 and 2014 due to the short-term maturity of these instruments. Marketable securities and derivative liabilities are carried at fair value as of December 31, 2015 and 2014.

At December 31, 2015 and 2014, the Company’s investments in mortgage backed securities had a carrying value of $80.4 million and $68.0 million, respectively. The Company estimated the fair value of investment in mortgage backed securities at December 31, 2015 and 2014 to be approximately $110.2 million and $96.0 million, respectively. 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 expected, discounted cash flows to estimate the fair value.

Interest Rate Protection, Swap, and Forward Contracts

The Company uses interest rate swaps, interest rate cap contracts, and forward starting swaps to manage interest rate risks. 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 primarily uses interest rate swaps and interest rate caps as part of its cash flow hedging strategy.

The Company records all derivatives on its consolidated balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.

For derivatives designated for accounting purposes as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. For derivatives designated for accounting purposes as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (outside of earnings) and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. The Company assesses the initial and ongoing effectiveness of each hedging relationship by comparing the changes in fair value or cash flows of the derivative hedging instrument with the changes in fair value or cash flows of the designated hedged item or transaction.

For derivatives not designated for accounting purposes as cash flow hedges, changes in fair value are recognized in earnings. All of the Company’s interest rate swaps are considered cash flow hedges. The change in fair value of the total return swaps is reported as total return swap income in the consolidated statements of income.

Income Taxes

Generally in any year in which ESS qualifies as a real estate investment trust (“REIT”) under the Internal Revenue Code (the “IRC”), it is not subject to federal income tax on that portion of its income that it distributes to stockholders. No provision for federal income taxes, other than the taxable REIT subsidiaries discussed below, has been made in the accompanying consolidated financial statements for each of the years in the three-year period ended December 31, 2015 as ESS has elected to be and believes it qualifies under the IRC as a REIT and has made distributions during the periods in amounts to preclude ESS from paying federal income tax.

In order to maintain compliance with REIT tax rules, the Company utilizes taxable REIT subsidiaries for various revenue generating or investment activities. The taxable REIT subsidiaries are consolidated by the Company. The activities and tax related provisions, assets and liabilities are not material.

As a partnership, the Operating Partnership is not subject to federal or state income taxes except that in order to maintain ESS’s compliance with REIT tax rules that are applicable to ESS, the Operating Partnership utilizes taxable REIT subsidiaries for various revenue generating or investment activities. The taxable REIT subsidiaries are consolidated by the Operating Partnership.

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.

Changes in Accumulated Other Comprehensive Loss by Component

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

Accounting Estimates

The preparation of consolidated financial statements, in accordance with 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, and its notes receivable. 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.
