EXPLANATORY NOTE

This report combines the reports on Form 10-Q for the quarterly period ended June 30, 2017 of Equity Residential and ERP Operating Limited Partnership.  Unless stated otherwise or the context otherwise requires, references to “EQR” mean Equity Residential, a Maryland real estate investment trust (“REIT”), and references to “ERPOP” mean ERP Operating Limited Partnership, an Illinois limited partnership.  References to the “Company,” “we,” “us” or “our” mean collectively EQR, ERPOP and those entities/subsidiaries owned or controlled by EQR and/or ERPOP.  References to the “Operating Partnership” mean collectively ERPOP and those entities/subsidiaries owned or controlled by ERPOP.  The following chart illustrates the Company's and the Operating Partnership's corporate structure:

EQR is the general partner of, and as of June 30, 2017 owned an approximate 96.4% ownership interest in, ERPOP.  The remaining 3.6% interest is owned by limited partners.  As the sole general partner of ERPOP, EQR has exclusive control of ERPOP's day-to-day management. Management operates the Company and the Operating Partnership as one business. The management of EQR consists of the same members as the management of ERPOP.

The Company is structured as an umbrella partnership REIT (“UPREIT”) and EQR contributes all net proceeds from its various equity offerings to ERPOP.  In return for those contributions, EQR receives a number of OP Units (see definition below) in ERPOP equal to the number of Common Shares it has issued in the equity offering. The Company may acquire properties in transactions that include the issuance of OP Units as consideration for the acquired properties. Such transactions may, in certain circumstances, enable the sellers to defer in whole or in part, the recognition of taxable income or gain that might otherwise result from the sales.  This is one of the reasons why the Company is structured in the manner shown above.  Based on the terms of ERPOP's partnership agreement, OP Units can be exchanged with Common Shares on a one-for-one basis because the Company maintains a one-for-one relationship between the OP Units of ERPOP issued to EQR and the outstanding Common Shares.

The Company believes that combining the reports on Form 10-Q of EQR and ERPOP into this single report provides the following benefits:

• enhances investors' understanding of the Company 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 the Company and the Operating Partnership; and

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

The Company believes it is important to understand the few differences between EQR and ERPOP in the context of how EQR and ERPOP operate as a consolidated company.  All of the Company's property ownership, development and related business operations are conducted through the Operating Partnership and EQR has no material assets or liabilities other than its investment in ERPOP.  EQR's primary function is acting as the general partner of ERPOP.  EQR also issues equity from time to time, the net proceeds of which it is obligated to contribute to ERPOP, and guarantees certain debt of ERPOP, as disclosed in this report.  EQR does not have any indebtedness as all debt is incurred by the Operating Partnership.  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 EQR, which are contributed to the capital of ERPOP in exchange for additional partnership interests in ERPOP (“OP Units”) (on a one-for-one Common Share per OP Unit basis) or additional preference units in ERPOP (on a one-for-one preferred share per preference unit basis), the Operating Partnership generates all remaining capital required by the Company's business.  These sources include the Operating Partnership's working capital, net cash provided by operating activities, borrowings under its revolving credit facility and/or commercial paper program, the issuance of secured and unsecured debt and equity securities and proceeds received from disposition of certain properties and joint venture interests.

Shareholders' equity, partners' capital and noncontrolling interests are the main areas of difference between the consolidated financial statements of the Company and those of the Operating Partnership.  The limited partners of the Operating Partnership are accounted for as partners' capital in the Operating Partnership's financial statements and as noncontrolling interests in the Company's financial statements.  The noncontrolling interests in the Operating Partnership's financial statements include the interests of unaffiliated partners in various consolidated partnerships. The noncontrolling interests in the Company's financial statements include the same noncontrolling interests at the Operating Partnership level and limited partner OP Unit holders of the Operating Partnership.  The differences between shareholders' equity and partners' capital result from differences in the equity issued at the Company and Operating Partnership levels.

To help investors understand the differences between the Company and the Operating Partnership, this report provides separate consolidated financial statements for the Company and the Operating Partnership; a single set of consolidated notes to such financial statements that includes separate discussions of each entity's debt, noncontrolling interests and shareholders' equity or partners' capital, as applicable; and a combined Management's Discussion and Analysis of Financial Condition and Results of Operations section that includes discrete information related to each entity.

This report also includes separate Part I, Item 4. Controls and Procedures sections and separate Exhibits 31 and 32 certifications for each of the Company and the Operating Partnership in order to establish that the requisite certifications have been made and that the Company and the Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934 and 18 U.S.C. §1350.

In order to highlight the differences between the Company and the Operating Partnership, the separate sections in this report for the Company and the Operating Partnership specifically refer to the Company and the Operating Partnership.  In the sections that combine disclosure of the Company 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.

As general partner with control of ERPOP, EQR consolidates ERPOP for financial reporting purposes, and EQR essentially has no assets or liabilities other than its investment in ERPOP.  Therefore, the assets and liabilities of the Company and the Operating Partnership are the same on their respective financial statements.  The separate discussions of the Company 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.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.  In the opinion of management, all adjustments (consisting of normal recurring accruals) and certain reclassifications considered necessary for a fair presentation have been included.  Certain reclassifications have been made to the prior period financial statements in order to conform to the current year presentation.  These reclassifications did not have an impact on net income previously reported.  Operating results for the six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

In preparation of the Company’s financial statements in conformity with accounting principles generally accepted in the United States, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from these estimates.

The balance sheets at December 31, 2016 have been derived from the audited financial statements at that date but do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.

Income and Other Taxes

Due to the structure of EQR as a REIT and the nature of the operations of its operating properties, no provision for federal income taxes has been made at the EQR level.  In addition, ERPOP generally is not liable for federal income taxes as the partners recognize their proportionate share of income or loss in their tax returns; therefore no provision for federal income taxes has been made at the ERPOP level.  Historically, the Company has generally only incurred certain state and local income, excise and franchise taxes.  The Company has elected Taxable REIT Subsidiary (“TRS”) status for certain of its corporate subsidiaries and as a result, these entities will incur both federal and state income taxes on any taxable income of such entities after consideration of any net operating losses.

Deferred tax assets and liabilities applicable to the TRS are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.  These assets and liabilities are measured using enacted tax rates for which the temporary differences are expected to be recovered or settled.  The effects of changes in tax rates on deferred tax assets and liabilities are recognized in earnings in the period enacted.  The Company’s deferred tax assets are generally the result of tax affected suspended interest deductions, net operating losses, differing depreciable lives on capitalized assets and the timing of expense recognition for certain accrued liabilities.  As of June 30, 2017, the Company has recorded a deferred tax asset, which is fully offset by a valuation allowance due to the uncertainty of realization.  The Company currently anticipates electing REIT status for its primary TRS upon filing the 2016 tax return in the third quarter of 2017.  This election will be retroactive to January 1, 2016.

InFebruary2016,the FASB issued a new leases standard which sets out principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessors and lessees).  The new standard requires the following:

• Lessors – Leases will be accounted for using an approach that is substantially equivalent to existing guidance for operating, sales-type and financing leases, but aligned with the new revenue recognition standard.  Lessors will be required to allocate lease payments to separate lease and non-lease components of each lease agreement, with the non-lease components evaluated under the new revenue recognition standard.

19

• Lessees – Leases will be accounted for using a dual approach, classifying leases as either operating or finance based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee.  This classification will determine whether the lease expense is recognized on a straight-line basis over the term of the lease (for operating leases) or based on an effective interest method with a front-loaded expense recognition (for finance leases).  A lessee is also required to record a right-of-use asset and a lease liability on its balance sheet for all leases with a term of greater than 12 months regardless of their classification as operating or finance leases.  Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases.

The new standard will be effective for the Company beginning on January 1, 2019, with early adoption permitted, though the Company currently anticipates adopting the new standard on the effective date.  The new standard must be adopted using a modified retrospective method, which requires application of the new guidance at the beginning of the earliest comparative period presented and provides for certain practical expedients, which the Company currently anticipates electing.  The Company anticipates that its residential and retail/commercial leases where it is the lessor will continue to be accounted for as operating leases under the new standard.  Therefore, the Company does not currently anticipate significant changes in the accounting for its lease revenues.  The Company is also the lessee under various corporate office and ground leases, which it will be required to recognize right of use assets and related lease liabilities on its consolidated balance sheets upon adoption.  The Company currently anticipates that its corporate office leases where it is the lessee will continue to be accounted for as operating leases under the new standard.  Based on its anticipated election of the practical expedients, the Company would not be required to reassess the classification of existing ground leases and therefore these leases would continue to be accounted for as operating leases.  However, in the event we modify existing ground leases and/or enter into new ground leases after adoption of the new standard, such leases will likely be classified as finance leases.  The Company will continue to evaluate the impact of adopting the new leases standard on its consolidated results of operations and financial position.

In June 2016, the FASB issued a new standard which requires companies to adopt a new approach for estimating credit losses on certain types of financial instruments, such as trade and other receivables and loans.  The standard will require entities to estimate a lifetime expected credit loss for most financial instruments, including trade receivables.  The new standard will be effective for the Company beginning on January 1, 2020, with early adoption permitted beginning January 1, 2019.  TheCompanyiscurrentlyevaluatingtheimpactofadoptingthenewstandardonitsconsolidatedresultsofoperationsand financial position.

InAugust2016andOctober2016,theFASBissuednewstandardstoclarifyhowspecifictransactionsareclassifiedand presented on the statement of cash flows.  Among other clarifications, the new standards specifically provide guidance for the following items within the statement of cash flows which have required significant judgment in thepast:

• Cash payments related to debt prepayments or extinguishment costs are to be classified within financingactivities;

• The portion of the cash payment made to settle a zero-coupon bond or a bond with an insignificant cash coupon attributable to accreted interest related to a debt discount is to be classified as a cash outflow within operating activities, and the portion attributable to the principal is to be classified within financingactivities;

• Insurance settlement proceeds are to be classified based on the nature of theloss;

• Companies must elect to classify distributions received from equity method investees using either a cumulative earnings approach or a look-through approach and the election must be disclosed;and

• Restrictedcashwillbeincludedwithcashandcashequivalentsonthestatementofcashflows.  Totalcashandcash equivalents and restricted cash are to be reconciled to the related line items on the balancesheet.

InFebruary 2017,theFASB issuedanewstandardwhich clarifies the accounting treatment for partial sales of nonfinancial assets (i.e. real estate).  The standard clarifies that partial sales transactions include contributions of nonfinancial assets to a joint venture or other noncontrolled investee.  Companies must recognize a full gain or loss on transfers of nonfinancial assets to equity method investees.  The standard requires companies to derecognize distinct nonfinancial assets or distinct in substance nonfinancial assets in partial sale transactions when it does not have a controlling financial interest in the legal entity that holds the asset and transfers control of the asset.  Once the distinct nonfinancial asset is transferred, the company is required to measure any non-controlling interest it receives or retains at fair value and recognize a full gain or loss on the transaction.  If a company transfers ownership interests in a consolidated subsidiary and continues to maintain a controlling financial interest, the company does not derecognize the assets or liabilities, and accounts for the transaction as an equity transaction and no gain or loss is recognized. The new standard will be effective for the Company beginning on January 1, 2018 and early

adoption was permitted beginning on January 1, 2017.  The Company anticipates adopting the new standard concurrently with the new revenue recognition standard.  The new standard may be applied retrospectively to each prior period presented or prospectively with the cumulative effect recognized as of the date of adoption.  The Company is currently evaluating the impact of adopting the new standard on its consolidated results of operations and financial position.

The Company is the controlling partner in various consolidated partnerships owning 17 properties and 3,215 apartment units having a noncontrolling interest book value of $6.3 million at June 30, 2017.  The Company is required to make certain disclosures regarding noncontrolling interests in consolidated limited-life subsidiaries.  Of the consolidated entities described above, the Company is the controlling partner in limited-life partnerships owning four properties having a noncontrolling interest deficit balance of $7.4 million.  These four partnership agreements contain provisions that require the partnerships to be liquidated through the sale of their assets upon reaching a date specified in each respective partnership agreement.  The Company, as controlling partner, has an obligation to cause the property owning partnerships to distribute the proceeds of liquidation to the Noncontrolling Interests in these Partially Owned Properties only to the extent that the net proceeds received by the partnerships from the sale of their assets warrant a distribution based on the partnership agreements.  As of June 30, 2017, the Company estimates the value of Noncontrolling Interest distributions for these four properties would have been approximately $64.4 million (“Settlement Value”) had the partnerships been liquidated.  This Settlement Value is based on estimated third party consideration realized by the partnerships upon disposition of the four Partially Owned Properties and is net of all other assets and liabilities, including yield maintenance on the mortgages encumbering the properties, that would have been due on June 30, 2017 had those mortgages been prepaid.  Due to, among other things, the inherent uncertainty in the sale of real estate assets, the amount of any potential distribution to the Noncontrolling Interests in the Company's Partially Owned Properties is subject to change.  To the extent that the partnerships' underlying assets are worth less than the underlying liabilities, the Company has no obligation to remit any consideration to the Noncontrolling Interests in these Partially Owned Properties.

The equity positions of various individuals and entities that contributed their properties to the Operating Partnership in exchange for OP Units, as well as the equity positions of the holders of restricted units, are collectively referred to as the “Noncontrolling Interests – Operating Partnership”.  Subject to certain exceptions (including the “book-up” requirements of restricted units), the Noncontrolling Interests – Operating Partnership may exchange their Units with EQR for Common Shares on a one-for-one basis.  The carrying value of the Noncontrolling Interests – Operating Partnership (including redeemable interests) is allocated based on the number of Noncontrolling Interests – Operating Partnership Units in total in proportion to the number of Noncontrolling Interests – Operating Partnership Units in total plus the number of Common Shares.  Net income is allocated to the Noncontrolling Interests – Operating Partnership based on the weighted average ownership percentage during the period.

The Operating Partnership has the right but not the obligation to make a cash payment instead of issuing Common Shares to any and all holders of Noncontrolling Interests – Operating Partnership Units requesting an exchange of their OP Units with EQR.  Once the Operating Partnership elects not to redeem the Noncontrolling Interests – Operating Partnership Units for cash, EQR is obligated to deliver Common Shares to the exchanging holder of the Noncontrolling Interests – Operating Partnership Units.

TheNoncontrollingInterests–OperatingPartnershipUnitsareclassifiedaseithermezzanineequityorpermanentequity.  If EQR is required, either by contract or securities law, to deliver registered Common Shares, such Noncontrolling Interests – Operating Partnership are differentiated and referred to as “Redeemable Noncontrolling Interests – Operating Partnership”.  Instruments that require settlement in registered shares cannot be classified in permanent equity as it is not always completely within an issuer’s control to deliver registered shares.  Therefore, settlement in cash is assumed and that responsibility for settlement in cash is deemed to fall to the Operating Partnership as the primary source of cash for EQR, resulting in presentation in the mezzanine section of the balance sheet.  The Redeemable Noncontrolling Interests – Operating Partnership are adjusted to the greater of carrying value or fair market value based on the Common Share price of EQR at the end of each respective reporting period.  EQR has the ability to deliver unregistered Common Shares for the remaining portion of the Noncontrolling Interests – Operating Partnership Units that are classified in permanent equity at June 30, 2017 and December 31, 2016.

Net proceeds from EQR Common Share and Preferred Share (see definition below) offerings are contributed by EQR to ERPOP.  In return for those contributions, EQR receives a number of OP Units in ERPOP equal to the number of Common Shares it has issued in the equity offering (or in the case of a preferred equity offering, a number of preference units in ERPOP equal in number and having the same terms as the Preferred Shares issued in the equity offering).  As a result, the net offering proceeds from Common Shares and Preferred Shares are allocated between shareholders’ equity and Noncontrolling Interests – Operating Partnership to account for the change in their respective percentage ownership of the underlying equity of ERPOP.

The Limited Partners of the Operating Partnership as of June 30, 2017 include various individuals and entities that contributed their properties to the Operating Partnership in exchange for OP Units, as well as the equity positions of the holders of restricted units.  Subject to certain exceptions (including the “book-up” requirements of restricted units), Limited Partners may exchange their Units with EQR for Common Shares on a one-for-one basis.  The carrying value of the Limited Partner Units (including redeemable interests) is allocated based on the number of Limited Partner Units in total in proportion to the number of Limited Partner Units in total plus the number of General Partner Units.  Net income is allocated to the Limited Partner Units based on the weighted average ownership percentage during the period.

The Operating Partnership has the right but not the obligation to make a cash payment instead of issuing Common Shares to any and all holders of Limited Partner Units requesting an exchange of their OP Units with EQR.  Once the Operating Partnership elects not to redeem the Limited Partner Units for cash, EQR is obligated to deliver Common Shares to the exchanging limited partner.

The Limited Partner Units are classified as either mezzanine equity or permanent equity.  If EQR is required, either by contract or securities law, to deliver registered Common Shares, such Limited Partner Units are differentiated and referred to as “Redeemable Limited Partner Units”.  Instruments that require settlement in registered shares cannot be classified in permanent equity as it is not always completely within an issuer's control to deliver registered shares.  Therefore, settlement in cash is assumed and that responsibility for settlement in cash is deemed to fall to the Operating Partnership as the primary source of cash for EQR, resulting in presentation in the mezzanine section of the balance sheet.  The Redeemable Limited Partner Units are adjusted to the greater of carrying value or fair market value based on the Common Share price of EQR at the end of each respective reporting period.  EQR has the ability to deliver unregistered Common Shares for the remaining portion of the Limited Partner Units that are classified in permanent equity at June 30, 2017 and December 31, 2016.

In September 2009, the Company announced the establishment of an At-The-Market (“ATM”) share offering program which would allow EQR to sell Common Shares from time to time into the existing trading market at current market prices as wellasthroughnegotiatedtransactions.  PerthetermsofERPOP'spartnershipagreement,EQRcontributesthenetproceedsfrom all equity offerings to the capital of ERPOP in exchange for additional OP Units (on a one-for-one Common Share per OP Unit basis).  The program currently has a maturity of June 2019.  EQR has the authority to issue 13.0 million shares but has not issued any shares under this program since September 2012.

The Company may repurchase up to 13.0 million Common Shares under its share repurchase program.  No shares were repurchased during the six months ended June 30, 2017 and as a result, EQR has remaining authorization to repurchase up to 13.0 million of its shares under the repurchase program as of June 30, 2017.

Note: The above tables exclude EQR's ownership interest in ERPOP, private equity fund investments, and the Company's interests in unconsolidated joint ventures established in connection with the acquisition of certain real estate related assets from Archstone Enterprise LP ("Archstone").  These ventures owned certain Archstone assets and succeeded to certain residual Archstone liabilities/litigation, as well as responsibility for tax protection arrangements and third-party preferred interests in former Archstone subsidiaries.  The preferred interests had an aggregate liquidation value of $39.5 million at June 30, 2017.  The ventures are owned 60% by the Company.  See below for further discussion.  

Operating Properties

The Company has various equity interests in certain limited partnerships owning 16 properties containing 2,783 apartment units.  Each partnership owns a multifamily property.  The Company is the general partner of these limited partnerships and is responsible for managing the operations and affairs of the partnerships as well as making all decisions regarding the businesses of the partnerships.  The limited partners are not able to exercise substantive kick-out or participating rights.  As a result, the partnerships qualify as VIEs.  The Company has a controlling financial interest in the VIEs and, thus, is the VIEs' primary beneficiary.  The Company has both the power to direct the activities of the VIEs that most significantly impact the VIEs' economic performance as well as the obligation to absorb losses or the right to receive benefits from the VIEs that could potentially be significant to the VIEs.  As a result, the partnerships are required to be consolidated on the Company's balance sheet.

The Company has a 75% equity interest in the Wisconsin Place joint venture.  The project contains a mixed-use site located in Chevy Chase, Maryland consisting of residential, retail, office and accessory uses, including underground parking facilities.  The joint venture owns the 432 unit residential component, but has no ownership interest in the retail and office components.  At June 30, 2017, the residential component had a net book value of $168.2 million.  The Company is the managing member and is responsible for conducting all administrative day-to-day matters and affairs of the joint venture as well as implementing all decisions with respect to the joint venture.  The limited partner is not able to exercise substantive kick-out or participating rights.  As a result, the joint venture qualifies as a VIE.  The Company has a controlling financial interest in the VIE and, thus, is the VIE's primary beneficiary.  The Company has both the power to direct the activities of the VIE that most significantly impact the VIE's economic performance as well as the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.  As a result, the entity that owns the residential component is required to be consolidated on the Company's balance sheet.

The Wisconsin Place joint venture also retains an unconsolidated interest in an entity that owns the land underlying the entire project and owns and operates the parking facility.  At June 30, 2017, the basis of this investment was $45.7 million.  The joint venture, as a limited partner, does not have substantive kick-out or participating rights in the entity.  As a result, the entity qualifies as a VIE.  The joint venture does not have a controlling financial interest in the VIE and is not the VIE's primary beneficiary.  The joint venture does not have the power to direct the activities of the VIE that most significantly impact the VIE's economic performance or the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.  As a result, the entity that owns the land and owns and operates the parking facility is unconsolidated and recorded using the equity method of accounting.

The Company has a 20% equity interest in each of the Nexus Sawgrass and Domain joint ventures.  The Nexus Sawgrass joint venture owns a 501 unit apartment property located in Sunrise, Florida and the Company's interest had a basis of $4.6 million at June 30, 2017.  The Domain joint venture owns a 444 unit apartment property located in San Jose, California and the Company's interest had a basis of $8.7 million at June 30, 2017.  Both properties were funded with long-term, non-recourse secured loans from the partner.  The mortgage loan on Nexus Sawgrass has a current unconsolidated outstanding balance of $48.6 million, bears interest at 5.60% and matures January 1, 2021.  The mortgage loan on Domain has a current unconsolidated outstanding balance of $96.8 million, bears interest at 5.75% and matures January 1, 2022.  While the Company is the managing member of both of the joint ventures, the joint venture partner has significant participating rights and has active involvement in and oversight of the operations.  As a result, the entities do not qualify as VIEs.  The Company alone does not have the power to direct the activities of the entities that most significantly impact the entities' economic performance and as a result, the entities are unconsolidated and recorded using the equity method of accounting.

Other

As the sole general partner of ERPOP, EQR has exclusive control of ERPOP's day-to-day management.  The limited partners are not able to exercise substantive kick-out or participating rights.  As a result, ERPOP qualifies as a VIE.  EQR has a controlling financial interest in ERPOP and, thus, is ERPOP's primary beneficiary.  EQR has the power to direct the activities of ERPOP that most significantly impact ERPOP's economic performance as well as the obligation to absorb losses or the right to receive benefits from ERPOP that could potentially be significant to ERPOP.  As a result, ERPOP is required to be consolidated on EQR's balance sheet.

In the first quarter of 2017, the Company agreed to a maximum investment of $5.0 million in a private equity fund which

29

primarily focuses on real estate technology investments.  The Company will account for the investment under the equity method of accounting.  As of June 30, 2017, the Company’s interest had a basis of approximately $0.9 million.

On February 27, 2013, in connection with the acquisition of Archstone, subsidiaries of the Company entered into three limited liability company agreements (collectively, the “Residual JV”).  The Residual JV owned certain Archstone assets and succeeded to certain residual Archstone liabilities/litigation.  The Residual JV is owned 60% by the Company and 40% by its joint venture partner.  TheCompany's basis at June 30, 2017 was a net obligation of $0.7 million.  The Residual JV is managed by a Management Committee consisting of two members from each of the Company and its joint venture partner.  Both partners have equal participation in the Management Committee and all significant participating rights are shared by both partners.  As a result, the Residual JV does not qualify as a VIE.  The Company alone does not have the power to direct the activities of the Residual JV that most significantly impact the Residual JV's economic performance and as a result, the Residual JV is unconsolidated and recorded using the equity method of accounting.  The Residual JV has sold all of the real estate assets that were acquired as part of the acquisition of Archstone, including all of the German assets, and is in the process of winding down all remaining activities.

On February 27, 2013, in connection with the acquisition of Archstone, a subsidiary of the Company entered into a limited liability company agreement (the “Legacy JV”), through which they assumed obligations of Archstone in the form of preferred interests, some of which are governed by tax protection arrangements.  At June 30, 2017, the remaining preferred interests had an aggregate liquidation value of $39.5 million, our share of which is included in other liabilities in the accompanying consolidated balance sheets.  Obligations of the Legacy JV are borne 60% by the Company and 40% by its joint venture partner.  The Legacy JV is managed by a Management Committee consisting of two members from each of the Company and its joint venture partner.  Both partners have equal participation in the Management Committee and all significant participating rights are shared by both partners.  As a result, the Legacy JV does not qualify as a VIE.  The Company alone does not have the power to direct the activities of the Legacy JV that most significantly impact the Legacy JV's economic performance and as a result, the Legacy JV is unconsolidated and recorded using the equity method of accounting.

9. Derivative and Other Fair ValueInstruments

The valuation of financial instruments requires the Company to make estimates and judgments that affect the fair value of the instruments.  The Company, where possible, bases the fair values of its financial instruments, including its derivative instruments, on listed market prices and third party quotes.  Where these are not available, the Company bases its estimates on current instruments with similar terms and maturities or on other factors relevant to the financial instruments.

In the normal course of business, the Company is exposed to the effect of interest rate changes.  The Company seeks to manage these risks by following established risk management policies and procedures including the use of derivatives to hedge interest rate risk on debt instruments.  The Company may also use derivatives to manage commodity prices in the daily operations of the business.

Athree-levelvaluationhierarchyexistsfordisclosureoffairvaluemeasurements.  Thevaluationhierarchyisbasedupon thetransparencyofinputstothevaluationofanassetorliabilityasofthemeasurementdate.  Afinancialinstrument’scategorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.  The three levels are defined asfollows:

• Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

• Level 2 – Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

• Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair valuemeasurement.

The Company’s derivative positions are valued using models developed by the respective counterparty as well as models developed internally by the Company that use as their basis readily observable market parameters (such as forward yield curves and credit default swap data).  Employee holdings other than Common Shares within the supplemental executive retirement plan (the “SERP”) are valued using quoted market prices for identical assets and are included in other assets and other liabilities on the consolidated balance sheets.  Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners are valued using the quoted market price of Common Shares.  The fair values disclosed for mortgage notes payable and unsecured debt (including its commercial paper) were calculated using indicative rates provided by lenders of similar loans in the case of mortgage notes payable and the private unsecured debt (including its commercial paper) and quoted market prices for each underlying issuance in the case of the public unsecured notes.

11. IndividuallySignificantDispositions

The Company executed an agreement with controlled affiliates of Starwood Capital Group ("Starwood") on October 23, 2015 to sell a portfolio of 72 operating properties consisting of 23,262 apartment units located in five markets across the United States for $5.365 billion (the "Starwood Transaction" or “Starwood Portfolio”).  The Starwood Portfolio represented substantially all of the assets in the Company’s South Florida and Denver markets and certain suburban assets in the Washington D.C., Seattle and Los Angeles markets.  On January 26 and 27, 2016, the Company closed on the sale of the entire portfolio described above.

37

The Company concluded that the Starwood Transaction did not qualify for discontinued operations reporting as it did not represent a strategic shift that had a major effect on the Company’s operations and financial results.  The Company has been investing only in its six coastal markets (Boston, New York, Washington D.C., Southern California, San Francisco and Seattle) and has not been acquiring or developing any new assets in its other markets.  Over the past several years, the Company has been repositioning its portfolio by selling its suburban assets located in markets outside its six core coastal markets.  The sale of the Starwood Portfolio represented the continuation of the above strategy.  However, the Company concluded that the Starwood Transaction did qualify as an individually significant component of the Company as the amount received upon disposal exceeded10%of total assets, and NOI (see definition in Note 13) of the Starwood Portfolio represented approximately 2.3% of consolidated NOI (for the approximate one-month period owned in 2016) for the six months ended June 30, 2016 and approximately 15.7% of consolidated NOI for the year ended December 31, 2015.  As a result, the following table summarizes the results of operations attributable to the Starwood Transaction for the six months and quarter ended June 30, 2016 (amounts in thousands):

12. Commitments andContingencies

The Company, as an owner of real estate, is subject to various Federal, state and local environmental laws.  Compliance by the Company with existing laws has not had a material adverse effect on the Company.  However, the Company cannot predict the impact of new or changed laws or regulations on its current properties or on properties that it may acquire in the future.  As of June 30, 2017, the Company does have an environmental reserve of approximately $3.9 million related to vacant land that it owns adjacent to one of its operating properties.

TheCompanyhasestablishedareserverelatedtovariouslitigationmattersassociatedwithitsMassachusettsproperties and periodically assesses the adequacy of the reserve and makes adjustments as necessary.  As of June 30, 2017,the reserve totaled approximately $0.9million.  While no assurances can be given, the Company does not believe that the ultimate resolution of any of these remaining litigation matters, if adversely determined, would have a material adverse effect on the Company.

The Company does not believe there is any other litigation pending or threatened against it that, individually or in the aggregate, may reasonably be expected to have a material adverse effect on the Company.

As of June 30, 2017, the Company has five wholly owned projects totaling 1,720 apartment units in various stages of development with commitments to fund of approximately $123.2 million and estimated completion dates ranging through December 31, 2018, as well as other completed development projects that are in various stages of lease up or are stabilized.

13. ReportableSegments

Operating segments are defined as components of an enterprise that engage in business activities from which they may earn revenues and incur expenses and about which discrete financial information is available that is evaluated regularly by the chiefoperatingdecisionmaker.  Thechiefoperatingdecisionmakerdecideshowresourcesareallocatedandassessesperformance on a recurring basis at leastquarterly.

The Company’s primary business is the acquisition, development and management of multifamily residential properties, which includes the generation of rental and other related income through the leasing of apartment units to residents.  The chief operating decision maker evaluates the Company's operating performance geographically by market and both on a same store and non-same store basis.  The Company’s same store operating segments located in its coastal markets represent its reportable segments.  The Company's operating segments located in its other markets (Phoenix) that are not material have also been included in the tables presented below.  

The Company’s fee and asset management and development activities are other business activities that do not constitute an operating segment and as such, have been aggregated in the "Other" category in the tables presented below.

The primary financial measure for the Company’s rental real estate segment is net operating income (“NOI”), which representsrentalincomeless:1) propertyandmaintenanceexpenseand2) realestatetaxesandinsuranceexpense(allasreflected in the accompanying consolidated statements of operations and comprehensive income).  TheCompanybelievesthat NOI is helpful to investors as a supplemental measure of its operating performance because it is a direct measure of the actual operating results of the Company’s apartment properties.  Revenues for all leases are reflected on a straight-line basis in accordance with GAAP for the current and comparable periods.

Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

For further information including definitions for capitalized terms not defined herein, refer to the consolidated financial statements and footnotes thereto included in the Company’s and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2016.

Forward-Looking Statements

Forward-looking statements are intended to be made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.  These statements are based on current expectations, estimates, projections and assumptions made by management.  While the Company's management believes the assumptions underlying its forward-looking statements are reasonable, such information is inherently subject to uncertainties and may involve certain risks, which could cause actual results, performance or achievements of the Company to differ materially from anticipated future results, performance or achievements expressed or implied by such forward-looking statements.  Many of these uncertainties and risks are difficult to predict and beyond management's control.  Forward-looking statements are not guarantees of future performance, results or events.  The forward-looking statements contained herein are made as of the date hereof and the Company undertakes no obligation to update or supplement these forward-looking statements.  Factors that might cause such differences include, but are not limited to the following:

• We intend to actively acquire, develop and rehab multifamily properties for rental operations as market conditions dictate.  We may also acquire multifamily properties that are unoccupied or in the early stages of lease up.  We may be unable to lease up these apartment properties on schedule, resulting in decreases in expected rental revenues and/or lower yields due to lower occupancy and rental rates as well as higher than expected concessions or higher than expected operating expenses.  We may not be able to achieve rents that are consistent with expectations for acquired, developed or rehabbed properties.  We may underestimate the costs necessary to bring an acquired property up to standards established for its intended market position, to complete a development property or to complete a rehab.  Additionally, we expect that other real estate investors with capital will compete with us for attractive investment opportunities or may also develop properties in markets where we focus our development and acquisition efforts.  This competition (or lack thereof) may increase (or depress) prices for multifamily properties.  We may not be in a position or have the opportunity in the future to make suitable property acquisitions on favorable terms.  We have acquired in the past and intend to continue to pursue the acquisition of properties, including large portfolios of properties, that could increase our size and result in alterations to our capital structure.  The total number of apartment units under development, costs of development and estimated completion dates are subject to uncertainties arising from changing economic conditions (such as the cost of labor and construction materials), competition and local government regulation;

• Debt financing and other capital required by the Company may not be available or may only be available on adverse terms;

• Labor and materials required for maintenance, repair, capital expenditure or development may be more expensive than anticipated;

• Occupancy levels and market rents may be adversely affected by national and local political, economic and market conditions including, without limitation, new construction and excess inventory of multifamily and owned housing/ condominiums, increasing portions of owned housing/condominium stock being converted to rental use, rental housing subsidized by the government, other government programs that favor single family rental housing or owner occupied housing over multifamily rental housing, slow or negative employment growth and household formation, the availability of low-interest mortgages or the availability of mortgages requiring little or no down payment for single family home buyers, changes in social preferences, governmental regulations (including rent control legislation and restrictions) and the potential for geopolitical instability, all of which are beyond the Company's control; and

Overview

Equity Residential (“EQR”), a Maryland real estate investment trust (“REIT”) formed in March 1993, is an S&P 500 company focused on the acquisition, development and management of rental apartment properties in urban and high-density suburban coastal gateway markets where today's renters want to live, work and play.  ERP Operating Limited Partnership (“ERPOP”), an Illinois limited partnership, was formed in May 1993 to conduct the multifamily residential property business of Equity Residential.  EQR has elected to be taxed as a REIT.  References to the “Company,” “we,” “us” or “our” mean collectively EQR, ERPOP and those entities/subsidiaries owned or controlled by EQR and/or ERPOP. References to the “Operating Partnership” mean collectively ERPOP and those entities/subsidiaries owned or controlled by ERPOP.

EQR is the general partner of, and as of June 30, 2017 owned an approximate 96.4% ownership interest in, ERPOP.  All of the Company’s property ownership, development and related business operations are conducted through the Operating Partnership and EQR has no material assets or liabilities other than its investment in ERPOP.  EQR issues equity from time to time, the net proceeds of which it is obligated to contribute to ERPOP, but does not have any indebtedness as all debt is incurred by the Operating Partnership.  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.

The Company’s corporate headquarters is located in Chicago, Illinois and the Company also operates property management offices in each of its six core coastal markets.  As of June 30, 2017, the Company had approximately 2,700 employees who provided real estate operations, leasing, legal, financial, accounting, acquisition, disposition, development and other support functions.

Business Objectives and Operating and Investing Strategies

The Company’s and the Operating Partnership’s business objectives and operating and investing strategies have not changed from the information included in the Company’s and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2016.

Current Environment

During the six months ended June 30, 2017, the Company acquired one property consisting of 136 apartment units for approximately $57.0 million and sold three consolidated rental properties consisting of 904 apartment units for approximately $266.7 million.  The Company also sold one land parcel for approximately $33.5 million during the six months ended June 30, 2017.  The Company currently budgets consolidated rental property acquisitions of approximately $500.0 million ($57.0 million of which already occurred during the six months ended June 30, 2017) during the year ending December 31, 2017 to be funded with proceeds from rental property dispositions.  The Company currently budgets consolidated rental property dispositions of approximately $500.0 million ($266.7 million of which already occurred during the six months ended June 30, 2017) during the year ending December 31, 2017.

The Company has been reducing its development spending and starts in response to high land prices and low projected returns on investment.  During the six months ended June 30, 2017, the Company did not start any development projects and substantially completed construction on one project representing 344 apartment units totaling approximately $108.7 million of development costs.  The Company has budgeted starting approximately $100.0 million of new development projects during the year ending December 31, 2017.  We currently budget spending approximately $300.0 million on development costs during the year ending December 31, 2017, primarily for projects currently under construction.  We expect that this capital will be primarily sourced with excess operating cash flow, future debt offerings and borrowings on our revolving credit facility and/or commercial paper program.

43

We currently have access to multiple sources of capital including the equity markets as well as both the secured and unsecured debt markets.  ERPOP now maintains long-term senior debt ratings of A- with Standard & Poor’s and Fitch and A3 with Moody’s, as Moody’s recently upgraded us effective July 17, 2017.  In August 2017, the Company completed a $400.0 million unsecured ten-year note offering with a coupon of 3.25% and an all-in effective interest rate of approximately 3.30% and completed a $300.0 million unsecured thirty-year note offering with a coupon of 4.00% and an all-in effective interest rate of approximately 4.10%.

We believe that cash and cash equivalents, securities readily convertible to cash, excess operating cash flow, current availability on our revolving credit facility and commercial paper program, future debt offerings and disposition proceeds for 2017 will provide sufficient liquidity to meet our funding obligations relating to asset acquisitions, debt maturities and/or prepayments, and existing and new development projects through 2017.  We expect that our remaining longer-term funding requirements will be met through some combination of new borrowings, equity issuances, property dispositions, joint ventures and cash generated from operations.

Same store revenues increased 2.3% during the six months ended June 30, 2017 as compared to the six months ended June 30, 2016, which was ahead of our expectations.  As a result, the Company now anticipates same store revenue increases ranging from 1.75% to 2.25%, as compared to the original guidance range of 1.0% to 2.25% that was provided in February 2017.  The Company’s primary goal in 2017 is to focus on retaining existing residents to drive renewal rate growth, which came in at 4.8% and 4.3% for the second quarter of 2017 and the first quarter of 2017, respectively.  Same store turnover declined by 0.7% for the first half of 2017 as compared to the same period in 2016.  With same store occupancy of 95.9% for the six months ended June 30, 2017, we also increased our occupancy expectations for full year 2017 from 95.7% to 95.8%.

Washington D.C. was originally expected to post improved same store revenue results for 2017 as compared to 2016 as continuing job growth allowed the elevated levels of new supply in this market to be absorbed.  During the second quarter of 2017, this job growth weakened throughout the market.  Same store revenues increased 1.4% in the six months ended June 30, 2017 as compared to the same period in 2016, which was lower than our original expectations.  We expect to produce same store revenue growth of approximately 1.4% in 2017, which is relatively consistent with the prior year and slightly lower than our original expectations of 1.8% for this market.

In the New York market, elevated deliveries of new luxury supply are having an impact on our ability to raise rents as renters trend towards affordability over neighborhood loyalty.  There has also been a reduction in the rate of job growth in the financial services sector and technology sector, which are important demand drivers in the market.  Due in part to our strong same store occupancy levels (96.0% for the six months ended June 30, 2017), we have used fewer concessions in the first half of 2017 than we originally expected and anticipate that trend to continue in the second half of 2017. As a result, same store revenues were flat in the six months ended June 30, 2017 as compared to the same period in 2016, which was slightly above our expectations.  We still expect there to be a decline in same store revenues of approximately 0.3% for full year 2017, which is better than our original expectations of a decline of 1.5% for this market.

We have a cautious outlook for Boston as the market continues to feel the impact from an elevated level of deliveries of new supply in the downtown and Cambridge submarkets with approximately 75% of this new supply competing with our properties.  Job growth has continued to improve in the market which is a positive sign that the additional supply may be absorbed without significant disruption.  Same store revenues increased 1.5% in the six months ended June 30, 2017 as compared to the same period in 2016, which was consistent with our expectations.  We expect to produce same store revenue growth of approximately 1.5%in 2017, which is consistent with our original expectations for this market.

Seattle is producing solid rental rate growth driven by the continued growth in technology jobs in the market.  While new supply remains elevated in this market, the strong job growth has enabled that supply to be quickly absorbed with little market disruption.  Same store revenues increased 6.3% in the six months ended June 30, 2017 as compared to the same period in 2016, which exceeded our expectations.  We expect Seattle to produce same store revenue growth of approximately 5.75% in 2017, which is better than our original expectations of 4.25% for this market.

44

San Francisco experienced significant volatility during 2016 peak leasing season as certain submarkets experienced elevated levels of new luxury supply combined with slower job growth in the technology sector.  Thus far in 2017, the market seems to have stabilized with the lease-up environment generally more accommodating.  While job growth in San Francisco appears to have slowed compared to previous years, it still remains above the national average.  As a result, we continue to see strong demand throughout the market, although the rate at which we can increase rents remains somewhat modest. Same store revenues increased 2.5% in the six months ended June 30, 2017 as compared to the same period in 2016, which was slightly ahead of our expectations.  We expect to produce same store revenue growth of approximately 1.8% in 2017, which is better than our original expectations of 1.0% for this market.

Southern California, which includes Los Angeles, Orange County and San Diego, is performing well and is positioned to be one of our better performing markets in 2017.  Widely dispersed new supply, very good economic growth and adequate levels of job growth in the market are driving strong revenue growth. Same store revenues increased 4.0% in the six months ended June 30, 2017 as compared to the same period in 2016, which was consistent with our expectations.  We expect to produce same store revenue growth of approximately 3.8%in 2017, which is consistent with our original expectations for this market.  We expect Orange County and San Diego to perform slightly better than Los Angeles for full year 2017 as compared to 2016.

Same store expenses increased 3.9% during the six months ended June 30, 2017 as compared to the six months ended June 30, 2016.  The Company anticipates that 2017 same store expenses will increase 3.25% to 4.0% as compared to the original guidance range of 3.0% to 4.0% that was provided in February 2017, significantly impacted by the following items:

• Real estate taxes increased 4.2% during the six months ended June 30, 2017 as compared to the same period in 2016 and are estimated to increase between 4.0% and 4.5% for the full year 2017 as compared to 2016 due primarily to increased values, mainly in Boston and Seattle.  We also expect 1.8 percentage points of the increase to come from 421-a tax abatement benefits expiring in New York;

• Payroll costs increased 6.3% during the six months ended June 30, 2017 as compared to the same period in 2016 and are estimated to increase 6.0% for the full year 2017 as compared to 2016 (compared to the original guidance range of 4.0% to 5.0%) primarily due to an increase in on-site staffing to assure the service levels necessary to remain competitive with new supply, higher on-site wages due to competition from new supply and higher medical and workers compensation costs than originally anticipated;

• Utilities increased 2.0% during the six months ended June 30, 2017 as compared to the same period in 2016 and are estimated to increase approximately 2.0% for the full year 2017 as compared to 2016 primarily due to moderate increases in natural gas costs, partially offset by lower gas usage and lower prices for electricity;

• Repairs and maintenance expenses increased 3.5% during the six months ended June 30, 2017 as compared to the same period in 2016.  Included in this category are approximately $0.7 million of costs incurred as a result of significant wind and rain storm damage in California in January 2017.  Without the California wind and rain storm damage costs, same store repair and maintenance expenses would have only increased 1.6% during the six months ended June 30, 2017 as compared to the same period in 2016.  This category is estimated to increase between 3.0% and 4.0% for the full year 2017 as compared to 2016 primarily due to approximately $1.0 million in costs related to minimum wage increases that impact our outside cleaning and landscaping vendors and the approximate $0.7 million in storm damage costs noted above; and

• Leasing and advertising increased 7.5% during the six months ended June 30, 2017 as compared to the same period in 2016.  The increase was driven by increased resident referral and broker fees (especially in New York and San Francisco) and higher spending on resident activities as part of our focus on retaining those residents.  Despite the increase in the first six months of 2017, we expect this category to be flat for the full year 2017 as compared to 2016.

Same store NOI increased 1.7% during the six months ended June 30, 2017 as compared to the six months ended June 30, 2016, which was ahead of our expectations.  As a result, the Company now anticipates same store NOI increases ranging from 0.75% to 1.75%, as compared to the original guidance range of 0.0% to 2.0% that was provided in February 2017, for the full year 2017 as a result of the above same store revenue and expense expectations.

The Company expects total overhead costs (property management expense and general and administrative expense) to decline approximately $3.0 million in 2017 over 2016 as we have largely completed right sizing our overhead platform to our smaller asset size.  As certain of the Company's overhead costs are fixed and/or not quickly scalable, the Company anticipates overhead costs as a percentage of total revenues will remain elevated as compared to 2015 levels, though slightly lower as compared to 2016 levels.

45

We believe that the Company is well-positioned in the long-term as a result of favorable demographics and increasing consumer preferences for the flexibility of rental housing.  As of June 30, 2017, the Company's same store occupancy was 95.8% and its total portfolio-wide occupancy, which includes development properties in various stages of lease-up, was 93.9%.  We believe our markets/metro areas will continue to see increased luxury multifamily supply, especially in our urban core locations, and there will continue to be periods of disruption as new development projects lease up.  We believe over the longer term that our markets will absorb future supply because of the strong long-term demand in these markets as exhibited by our current high occupancy levels and increasing household formations.  We have seen evidence of this in Seattle as elevated levels of new supply have been absorbed and rental rates continue to grow.  We also anticipate supply declining in our markets beginning in 2018, with the possible exception of New York, because of high construction costs, lower revenue growth and development lenders materially reducing their lending activities due to regulatory pressures and concerns over markets being overbuilt.

The current environment information presented above is based on current expectations and is forward-looking.

Results of Operations

In conjunction with our business objectives and operating strategy, the Company continued to invest in apartment properties located in our six coastal markets and sell apartment properties located primarily in the less dense portion of suburban markets and/or properties that are functionally or locationally challenged during the six months ended June 30, 2017 as follows:

• Acquired one consolidated apartment property consisting of 136 apartment units for approximately $57.0 million, at an Acquisition Cap Rate (see definition below) of 5.0%;

• Sold three consolidated apartment properties consisting of 904 apartment units for approximately $266.7 million, at a weighted average Disposition Yield (see definition below) of 5.3% and generating an Unlevered IRR (see definition below) of 14.1%; and

• Substantially completed construction on one project consisting of 344 apartment units totaling approximately $108.7 million of development costs and stabilized two development projects consisting of 801 apartment units totaling $514.0 million of development costs.

The Company's primary financial measure for evaluating each of its apartment communities is net operating income (“NOI”).  NOI represents rental income less direct property operating expenses (including real estate taxes and insurance).  The Company believes that NOI is helpful to investors as a supplemental measure of its operating performance because it is a direct measure of the actual operating results of the Company’s apartment properties.

The definition of certain terms described above or below are as follows:

• Acquisition Cap Rate – NOI that the Company anticipates receiving in the next 12 months (or the year two or three stabilized NOI for properties that are in lease-up at acquisition) less an estimate of property management costs/management fees allocated to the project (generally ranging from 2.0% to 4.0% of revenues depending on the size and income streams of the asset) and less an estimate for in-the-unit replacement capital expenditures (generally ranging from $100-$450 per apartment unit depending on the age and condition of the asset) divided by the gross purchase price of the asset.  The weighted average Acquisition Cap Rate for acquired properties is weighted based on the projected NOI streams and the relative purchase price for each respective property.

• Disposition Yield – NOI that the Company anticipates giving up in the next 12 months less an estimate of property management costs/management fees allocated to the project (generally ranging from 2.0% to 4.0% of revenues depending on the size and income streams of the asset) and less an estimate for in-the-unit replacement capital expenditures (generally ranging from $100-$450 per apartment unit depending on the age and condition of the asset) divided by the gross sale price of the asset.  The weighted average Disposition Yield for sold properties is weighted based on the projected NOI streams and the relative sales price for each respective property.

• Unlevered Internal Rate of Return (“IRR”) – The Unlevered IRR on sold properties is the compound annual rate of return calculated by the Company based on the timing and amount of: (i) the gross purchase price of the property plus any direct acquisition costs incurred by the Company; (ii) total revenues earned during the Company’s ownership period; (iii) total direct property operating expenses (including real estate taxes and insurance) incurred during the Company’s ownership period; (iv) capital expenditures incurred during the Company’s ownership period; and (v) the gross sales price of the property net of selling costs.  Each of the items (i) through (v) is calculated in accordance with generally accepted accounting principles (“GAAP”).  

Properties that the Company owned and were stabilized (see definition below) for all of both of the six months ended June 30,

46

2017 and 2016 (the “Six-Month 2017 Same Store Properties”), which represented 70,400 apartment units, and properties that the Company owned and were stabilized for all of both of the quarters ended June 30, 2017 and 2016 (the “Second Quarter 2017 Same Store Properties”), which represented 71,354 apartment units, impacted the Company’s results of operations.  Both the Six-Month 2017 Same Store Properties and the Second Quarter 2017 Same Store Properties are discussed in the following paragraphs.

The following tables provide a rollforward of the apartment units included in Same Store Properties and a reconciliation of apartment units included in Same Store Properties to those included in Total Properties for the six months and quarter ended June 30, 2017:

Note: Properties are considered "stabilized" when they have achieved 90% occupancy for three consecutive months.  Properties are included in Same Store when they are stabilized for all of the current and comparable periods presented.

(1) Consists of one property containing 285 apartment units (Playa Pacifica in Hermosa Beach, California) which was removed from the same store portfolio in the first quarter of 2015 due to a major renovation in which significant portions of the property were taken offline for extended time periods and one property containing 71 apartment units (Acton Courtyard in Berkeley, California) which was removed from the same store portfolio in the third quarter of 2016 due to an affordable housing dispute which required significant portions of the property to be vacant for an extended releasing period.  As of June 30, 2017 and 2016, Playa Pacifica had an occupancy of 92.3% and 56.0%, respectively.  As of June 30, 2017 and September 30, 2016, Acton Courtyard had an occupancy of 97.2% and 67.6%, respectively.  These properties will not return to the same store portfolio until they are stabilized for all of the current and comparable periods presented.

(2) Consists of three properties containing 853 apartment units that are wholly owned by the Company but the entire projects are master leased to a third party corporate housing provider and the Company earns monthly net rental income.

(3) Consists of properties in various stages of lease-up and properties where lease-up has been completed but the properties were not stabilized for the comparable periods presented.

The Company’s acquisition, disposition and completed development activities also impacted overall results of operations for the six months and quarters ended June 30, 2017 and 2016.  The impacts of these activities are discussed in greater detail in the following paragraphs.

Comparison of the six months ended June 30, 2017 to the six months ended June 30, 2016

For the six months ended June 30, 2017, the Company reported diluted earnings per share/unit of $0.92 compared to $10.36 per share/unit in the same period of 2016.  The difference is primarily due to approximately $9.58 per share/unit in higher gains on

47

property sales and $0.12 per share/unit in higher gains on sales of non-operating assets in 2016 compared to 2017 as a direct result of the significant sales activity in 2016 compared to 2017, partially offset by $0.28 per share/unit in higher debt extinguishment costs incurred in 2016 as compared to 2017.

For the six months ended June 30, 2017, income from continuing operations decreased approximately $3.6 billion when compared to the six months ended June 30, 2016.  The decrease in continuing operations is discussed below.

For the six months ended June 30, 2017, consolidated rental income increased 0.4%, consolidated operating expenses (comprised of property and maintenance and real estate taxes and insurance) increased 2.2% and consolidated NOI decreased 0.3% when compared to the six months ended June 30, 2016.  The decline in NOI is primarily a result of the Company’s significant disposition activity in 2016, partially offset by improved NOI from same store and lease-up properties.

Revenues from the Six-Month 2017 Same Store Properties increased $25.5 million primarily as a result of an increase in average rental rates charged to residents.  Expenses from the Six-Month 2017 Same Store Properties increased $12.4 million primarily as a result of an increase in real estate taxes, on-site payroll costs, leasing and advertising and repairs and maintenance expenses.  The following tables provide comparative same store results and statistics for the Six-Month 2017 Same Store Properties:

The Company anticipates consolidated rental acquisitions of $500.0 million and consolidated rental dispositions of $500.0 million and expects that the Acquisition Cap Rate will be 0.50% lower than the Disposition Yield for the full year ending December 31, 2017.

These 2017 assumptions are based on current expectations and are forward-looking.

Non-same store NOI results decreased approximately $16.1 million compared to the first half of 2016 and consist primarily of properties acquired in calendar years 2016 and 2017, operations from the Company’s development properties and operations prior to disposition from 2016 and 2017 sold properties.  This decrease primarily resulted from:

• The lost NOI from 2016 and 2017 dispositions of $37.9 million; and

• A partial offset from development and newly stabilized development properties in lease-up of $19.2 million, operating properties acquired in 2016 and 2017 of $4.4 million, operating activities from other non-same store properties (including three master leased properties) of $0.9 million and operating activities from other miscellaneous operations.

See also Note 13 in the Notes to Consolidated Financial Statements for additional discussion regarding the Company’s segment disclosures.

Fee and asset management revenues decreased approximately $2.8 million or 88.5% primarily as a result of lower revenue earned on management of the Company's military housing ventures at Joint Base Lewis McChord due to the sale of the Company's entire interest in the management contracts and related rights associated with these ventures in the second quarter of 2016.

Property management expenses include off-site expenses associated with the self-management of the Company’s properties as well as management fees paid to any third party management companies.  These expenses decreased approximately $0.6 million or 1.4%.  This decrease is primarily attributable to a decrease in payroll-related costs, partially offset by increases in temporary contractors.  The Company anticipates that property management expenses will approximate $83.0 million to $85.0 million for the year ending December 31, 2017.  The above assumption is based on current expectations and is forward-looking.

General and administrative expenses, which include corporate operating expenses, decreased approximately $7.2 million or 20.6% primarily due to a decrease in payroll-related costs.  The Company anticipates that general and administrative expenses will approximate $50.0 million to $52.0 million for the year ending December 31, 2017, excluding charges of approximately $0.4 million related to the overlap of accounting costs for the Company's current and former executive compensation programs.  The above assumption is based on current expectations and is forward-looking.

Depreciation expense, which includes depreciation on non-real estate assets, increased approximately $9.9 million or 2.8% primarily as a result of additional depreciation expense on properties acquired in 2016 and 2017 and development properties placed in service, partially offset by lower depreciation from properties sold in 2016 and 2017.

Interest and other income decreased approximately $57.8 million or 97.0%.  This decrease is primarily attributable to the approximate $52.4 million gain from the sale of the Company's entire interest in the management contracts and related rights associated with the military housing ventures at Joint Base Lewis McChord during the six months ended June 30, 2016, along with the sale of the Company’s 421-a real estate tax certificates in 2016, both of which did not reoccur in 2017.  The Company anticipates that interest and other income will approximate $1.0 million for the year ending December 31, 2017, excluding certain non-comparable insurance/litigation settlement proceeds.  The above assumption is based on current expectations and is forward-looking.

Other expenses decreased approximately $1.9 million or 47.5% primarily due to a decrease in transaction and pursuit costs of approximately $2.4 million as a result of a decline in acquisitions and development in 2017 as compared to 2016, partially offset by an increase in litigation settlements.  In addition, the Company anticipates that substantially all of its transactions will now be accounted for as asset acquisitions, which means that transaction costs will largely be capitalized, as a result of its adoption of the new definition of a business standard effective January 1, 2017.  See Note 2 in the Notes to Consolidated Financial Statements for further discussion.

Interest expense, including amortization of deferred financing costs, decreased approximately $105.9 million or 34.4% primarily as a result of $107.8 million in lower debt extinguishment costs in 2017 as compared to 2016.  The effective interest cost on all indebtedness for the six months ended June 30, 2017 was 4.53% as compared to 4.70% for the six months ended June 30, 2016.  The Company anticipates that interest expense from continuing operations, excluding debt extinguishment costs/prepayment penalties, will approximate $367.6 million to $375.8 million and capitalized interest will approximate $24.0 million to $28.0 million for the year ending December 31, 2017.  The above assumptions are based on current expectations and are forward-looking.

Income and other tax expense decreased approximately $0.3 million or 36.8% primarily due to decreases in various state and local taxes related to the Company's elevated disposition activity in 2016 vs. 2017.  The Company anticipates that income and other tax expense will approximate $1.0 million for the year ending December 31, 2017.  The above assumption is based on current expectations and is forward-looking.

Net gain on sales of real estate properties decreased approximately $3.7 billion as a result of the sale of 83 consolidated

50

apartment properties (including the Starwood Portfolio) during the six months ended June 30, 2016 as compared to only three consolidated apartment property sales during the six months ended June 30, 2017, all of which did not meet the criteria for reporting discontinued operations.  See Note 11 in the Notes to Consolidated Financial Statements for further discussion.

Net gain on sales of land parcels increased approximately $7.4 million or 63.5% due to the gain on sale of one land parcel with a lower basis during the during the six months ended June 30, 2017 as compared to the gain on sales of three land parcels during the six months ended June 30, 2016.

Comparison of the quarter ended June 30, 2017 to the quarter ended June 30, 2016

For the quarter ended June 30, 2017, the Company reported diluted earnings per share/unit of $0.53 compared to $0.59 per share/unit in the same period of 2016.  The difference is primarily due to approximately $0.14 per share/unit in lower gains on sales of non-operating assets in the second quarter of 2017 compared to the same period in 2016 partially offset by approximately $0.08 per share/unit in higher gains on property sales in the second quarter of 2017 compared to the same period in 2016.

For the quarter ended June 30, 2017, income from continuing operations decreased approximately $24.2 million when compared to the quarter ended June 30, 2016.  The decrease in continuing operations is discussed below.

For the quarter ended June 30, 2017, consolidated rental income increased 2.9%, consolidated operating expenses (comprised of property and maintenance and real estate taxes and insurance) increased 7.5% and consolidated NOI increased 1.0% when compared to the quarter ended June 30, 2016. The increase in NOI is primarily a result of improved NOI from same store and lease-up properties.

Revenues from the Second Quarter 2017 Same Store Properties increased $11.8 million primarily as a result of an increase in average rental rates charged to residents and decrease in turnover.  Expenses from the Second Quarter 2017 Same Store Properties increased $6.6 million primarily as a result of an increase in real estate taxes, on-site payroll costs and utilities expenses.  The following tables provide comparative same store results and statistics for the Second Quarter 2017 Same Store Properties:

Non-same store NOI results decreased approximately $1.0 million compared to the second quarter of 2016 and consist primarily of

52

properties acquired in calendar years 2016 and 2017, operations from the Company’s development properties and operations prior to disposition from 2016 to 2017 sold properties.  This decrease primarily resulted from:

• The lost NOI from 2016 and 2017 dispositions of $9.2 million;

• A decrease in operating activities from other miscellaneous operations; and

• A partial offset from development and newly stabilized development properties in lease-up of $7.7 million, operating properties acquired in 2016 and 2017 of $1.4 million and operating activities from other non-same store properties (including three master leased properties) of $0.4 million.

See also Note 13 in the Notes to Consolidated Financial Statements for additional discussion regarding the Company’s segment disclosures.

Property management expenses include off-site expenses associated with the self-management of the Company’s properties as well as management fees paid to any third party management companies.  These expenses increased approximately $0.6 million or 2.8%.  This increase is primarily attributable to an increase in temporary contractors, computer operations and legal and professional fees, partially offset by decreases in payroll-related costs. 

General and administrative expenses, which include corporate operating expenses, decreased approximately $4.7 million or 25.5% primarily due to a decrease in payroll-related costs.

Depreciation expense, which includes depreciation on non-real estate assets, increased approximately $3.8 million or 2.1% primarily as a result of additional depreciation expense on properties acquired in 2016 and 2017 and development properties placed in service, partially offset by lower depreciation from properties sold in 2016 and 2017.

Interest and other income decreased approximately $55.4 million or 97.9%.  This decrease is primarily attributable to the approximate $52.4 million gain from the sale of the Company's entire interest in the management contracts and related rights associated with the military housing ventures at Joint Base Lewis McChord during the quarter ended June 30, 2016, along with the sale of the Company’s 421-a real estate tax certificates in 2016, both of which did not reoccur in 2017.

Other expenses decreased approximately $0.5 million or 30.7% primarily due to a decrease in transaction and pursuit costs as a result of a decline in acquisitions and development in 2017 as compared to 2016.  In addition, the Company anticipates that substantially all of its transactions will now be accounted for as asset acquisitions, which means that transaction costs will largely be capitalized, as a result of its adoption of the new definition of a business standard effective January 1, 2017.  See Note 2 in the Notes to Consolidated Financial Statements for further discussion.

Interest expense, including amortization of deferred financing costs, increased approximately $4.5 million or 5.1% primarily as a result of lower capitalized interest in the first six months of 2017 as compared to same period in 2016 as a result of the Company’s decline in development activity.  The effective interest cost on all indebtedness for the quarter ended June 30, 2017 was 4.45% as compared to 4.74% for quarter ended June 30, 2016.

Income and other tax expense decreased approximately $0.2 million or 46.7% primarily due to decreases in various state and local taxes related to the Company's elevated disposition activity in 2016 vs. 2017.

Net gain on sales of real estate properties increased approximately $30.4 million or 52.9% as a result of higher gains on the sale of two consolidated apartment properties during the quarter ended quarter ended June 30, 2017 as compared to the three consolidated property sales during the quarter ended June 30, 2016, all of which did not meet the criteria for reporting discontinued operations.  See Note 11 to Consolidate Financial Statements for further discussion.

Liquidity and Capital Resources

EQR issues public equity from time to time and guarantees certain debt of the Operating Partnership.  EQR does not have any indebtedness as all debt is incurred by the Operating Partnership.

As of January 1, 2017, the Company had approximately $77.2 million of cash and cash equivalents and the amount available on its revolving credit facility was $1.96 billion (net of $20.6 million which was restricted/dedicated to support letters of credit and net of $20.0 million in principal outstanding on the commercial paper program).  After taking into effect the various transactions discussed in the following paragraphs and the net cash provided by operating activities, the Company's cash and cash equivalents balance at June

53

30, 2017 was approximately $37.7 million and the amount available on its revolving credit facility was $1.22 billion (net of $12.1 million which was restricted/dedicated to support letters of credit, net of $265.0 million outstanding on the revolving credit facility and net of $500.0 million in principal outstanding on the commercial paper program).

During the six months ended June 30, 2017, the Company generated proceeds from various transactions, which included the following:

• Disposed of three consolidated rental properties and one land parcel, receiving net proceeds of approximately $297.3 million; and

• Issued approximately 0.2 million Common Shares related to share option exercises and ESPP purchases and received net proceeds of $10.3 million, which were contributed to the capital of the Operating Partnership in exchange for additional OP Units (on a one-for-one Common Share per OP Unit basis).

During the six months ended June 30, 2017, the above proceeds along with net cash flow from operations and borrowings from the Company's revolving line of credit and commercial paper program were primarily utilized to:

• Acquire one consolidated property for approximately $57.1 million in cash;

• Invest $175.9 million primarily in development projects;

• Repay $377.4 million of mortgage loans and incur prepayment penalties of approximately $12.3 million; and

• Repay $394.1 million of 5.750% unsecured notes at maturity.

In September 2009, EQR announced the establishment of an At-The-Market (“ATM”) share offering program which would allow EQR to sell Common Shares from time to time into the existing trading market at current market prices as well as through negotiated transactions.  Per the terms of ERPOP’s partnership agreement, EQR contributes the net proceeds from all equity offerings to the capital of ERPOP in exchange for additional OP Units (on a one-for-one Common Share per OP Unit basis).  EQR may, but shall have no obligation to, sell Common Shares through the ATM share offering program in amounts and at times to be determined by EQR.  Actual sales will depend on a variety of factors to be determined by EQR from time to time, including (among others) market conditions, the trading price of EQR’s Common Shares and determinations of the appropriate sources of funding for EQR.  The program currently has a maturity of June 2019.  EQR has the authority to issue 13.0 million shares but has not issued any shares under this program since September 2012.  Through July 28, 2017, EQR has cumulatively issued approximately 16.7 million Common Shares at an average price of $48.53 per share for total consideration of approximately $809.9 million.

Depending on its analysis of market prices, economic conditions and other opportunities for the investment of available capital, EQR may repurchase its Common Shares pursuant to its existing share repurchase program authorized by the Board of Trustees.  The Company may repurchase up to 13.0 million Common Shares under this program. No open market repurchases have occurred since 2008.  As of July 28, 2017, EQR has remaining authorization to repurchase up to 13.0 million of its shares.  

Depending on its analysis of prevailing market conditions, liquidity requirements, contractual restrictions and other factors, the Company may from time to time seek to repurchase and retire its outstanding debt in open market or privately negotiated transactions.

(1) Net of the effect of any derivative instruments.  Weighted average rates are as of June 30, 2017.

(3) Includes a $500.0 million 5.19% mortgage loan with a maturity date of October 1, 2019 that can be prepaid at par beginning October 1, 2018.

(4) Includes a $550.0 million 6.08% mortgage loan with a maturity date of March 1, 2020 that can be prepaid at par beginning March 1, 2019.  Also includes a $500.0 million 5.78% mortgage loan with a maturity date of July 1, 2020 that can be prepaid at par beginning July 1, 2019.

(5) Includes $265.0 million outstanding on the Company’s unsecured revolving credit facility.

EQR and ERPOP currently have an active universal shelf registration statement for the issuance of equity and debt securities that automatically became effective upon filing with the SEC on June 28, 2016 and expires on June 28, 2019.  Per the terms of ERPOP's partnership agreement, EQR contributes the net proceeds of all equity offerings to the capital of ERPOP in exchange for additional OP Units (on a one-for-one Common Share per OP Unit basis) or preference units (on a one-for-one preferred share per preference unit basis).

The Company generally expects to meet its short-term liquidity requirements, including capital expenditures related to maintaining its existing properties and scheduled unsecured note and mortgage note repayments, through its working capital, net cash provided by operating activities and borrowings under the Company’s revolving credit facility and commercial paper program.  Under normal operating conditions, the Company considers its cash provided by operating activities to be adequate to meet operating requirements and payments of distributions.

The Company has a flexible dividend policy which it believes will generate payouts closely aligned with the actual annual operating results of the Company’s core business and provide transparency to investors.  Beginning in 2014, the Company began paying its regular annual dividend based on 65% of the midpoint of the range of Normalized FFO guidance customarily provided as part of the Company's fourth quarter earnings release.  The Company expects the 2017 regular annual dividend payout will be $2.015 per share/unit and the Company intends to pay four regular quarterly dividends of $0.50375 per share/unit in 2017.  All future dividends remain subject to the discretion of the Board of Trustees. The above assumption is based on current expectations and is forward-looking.

While our current dividend policy makes it less likely that we will over distribute, it will also lead to a dividend reduction more quickly should operating results deteriorate or large portfolio sales occur.  However, whether due to changes in the dividend policy or otherwise, there may be times when the Company experiences shortfalls in its coverage of distributions, which may cause the Company to consider reducing its distributions and/or using the proceeds from property dispositions or additional financing transactions to make up the difference.  Should these shortfalls occur for lengthy periods of time or be material in nature, the Company's financial condition may be adversely affected and it may not be able to maintain its current distribution levels.  The Company believes that its expected 2017 operating cash flow will be sufficient to cover capital expenditures and regular dividends/distributions.

The Company also expects to meet its long-term liquidity requirements, such as lump sum unsecured note and mortgage debt maturities, property acquisitions, financing of construction and development activities through the issuance of secured and unsecured debt and equity securities, including additional OP Units, proceeds received from the disposition of certain properties and joint ventures and cash generated from operations after all distributions.  In addition, the Company has significant unencumbered properties available to secure additional mortgage borrowings in the event that the public capital markets are unavailable or the cost of alternative sources of capital is too high.  The fair value of and cash flow from these unencumbered properties are in excess of the requirements the Company must maintain in order to comply with covenants under its unsecured notes, line of credit and commercial paper program.  Of the $25.5 billion in investment in real estate on the Company’s balance sheet at June 30, 2017, $19.2 billion or 75.5% was unencumbered.  However, there can be no assurances that these sources of capital will be available to the Company in the future on acceptable terms or otherwise.

ERPOP's long-term senior debt ratings and short-term commercial paper ratings as well as EQR's long-term preferred equity ratings as of July 28, 2017 are as follows:

	Standard & Poor's	Moody's	Fitch
ERPOP's long-term senior debt rating	A-	A3 (1)	A-
ERPOP's short-term commercial paper rating	A-2	P-2	F-2
EQR's long-term preferred equity rating	BBB	Baa1 (1)	BBB

(1) The long-term credit ratings listed above reflect the one-level upgrade by Moody’s effective July 17, 2017.

On November 3, 2016, the Company replaced its existing $2.5 billion facility with a $2.0 billion unsecured revolving credit facility maturing January 10, 2022.  The Company has the ability to increase available borrowings by an additional $750.0 million by adding additional banks to the facility or obtaining the agreement of existing banks to increase their commitments.  The interest rate on advances under the facility will generally be LIBOR plus a spread (currently 0.825%), or based on bids received from the lending group, and the Company pays an annual facility fee (currently 12.5 basis points).  Both the spread and the facility fee are dependent on the credit rating of the Company's long-term debt.

On February 2, 2015, the Company entered into an unsecured commercial paper note program in the United States.  The Company may borrow up to a maximum of $500.0 million under this program subject to market conditions.  The notes will be sold under customary terms in the United States commercial paper note market and will rank pari passu with all of the Company's other unsecured senior indebtedness.  As of July 28, 2017, there was a balance of $500.0 million outstanding on the commercial paper program.

As of July 28, 2017, $415.0 million was outstanding and the amount available on the revolving credit facility was $1.07 billion (net of $12.1 million which was restricted/dedicated to support letters of credit, net of $415.0 million outstanding on the revolving credit facility and net of $500.0 million in principal outstanding on the commercial paper program).  This facility may, among other potential uses, be used to fund property acquisitions, costs for certain properties under development and short-term liquidity requirements.

See Note 14 in the Notes to Consolidated Financial Statements for discussion of the events which occurred subsequent to June 30, 2017.

Capitalization of Fixed Assets and Improvements to Real Estate

The Company’s and the Operating Partnership’s capital expenditures policy has not changed from the information included in the Company’s and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2016.

For the six months ended June 30, 2017, our actual capital expenditures to real estate included the following (amounts in thousands except for apartment unit and per apartment unit amounts):

57

Capital Expenditures to Real Estate

For the Six Months Ended June 30, 2017

	Total Apartment Units (1)		Replacements (2)		Avg. Per Apartment Unit		Building Improvements (3)		Avg. Per Apartment Unit		Total		Avg. Per Apartment Unit
Same Store Properties (4)		70,400	$	40,233	$	572	$	46,477	$	660	$	86,710	$	1,232
Non-Same Store Properties (5)		5,689		922		170		1,286		237		2,208		407
Other (6)		—		129				250				379
Total		76,089	$	41,284			$	48,013			$	89,297

(1) Total Apartment Units – Excludes 945 unconsolidated apartment units for which capital expenditures to real estate are self-funded and do not consolidate into the Company's results.

(2) Replacements – Includes new expenditures inside the apartment units such as appliances, mechanical equipment, fixtures and flooring, including carpeting.  Replacements for same store properties also include $22.0 million spent during the six months ended June 30, 2017 on apartment unit renovations/rehabs (primarily kitchens and baths) on approximately 1,650 same store apartment units (equating to approximately $13,300 per apartment unit rehabbed) designed to reposition these units for higher rental levels in their respective markets.  

(3) Building Improvements – Includes roof replacement, paving, amenities and common areas, building mechanical equipment systems, exterior painting and siding, major landscaping, vehicles and office and maintenance equipment.

(4) Same Store Properties – Primarily includes all properties acquired or completed that are stabilized prior to January 1, 2016, less properties subsequently sold.

(5) Non-Same Store Properties – Primarily includes all properties acquired during 2016 and 2017, plus any properties in lease-up and not stabilized as of January 1, 2016. Per apartment unit amounts are based on a weighted average of 5,421 apartment units.

(6) Other – Primarily includes expenditures for properties sold and properties under development.

The Company estimates that during 2017 it will spend approximately $2,600 per apartment unit of capital expenditures, inclusive of apartment unit renovation/rehab costs, or $1,900 per apartment unit excluding apartment unit renovation/rehab costs. During 2017, the Company expects to spend approximately $50.0 million for unit renovation/rehab costs on same store properties at an average cost of $11,000 per apartment unit rehabbed.  These anticipated amounts represent an increase as a percentage of rental revenues, in the cost per unit and in the absolute dollar amounts over 2016. These increases include approximately $17.0 million or approximately $250 per apartment unit of additional estimated expenditures for resident focused renovation projects such as common areas and fitness centers in order to remain competitive with the new luxury supply being delivered in many of our markets. We will continue to create value from our properties by doing those rehabs that meet our investment criteria.  The above assumptions are based on current expectations and are forward-looking.

During the six months ended June 30, 2017, the Company’s total non-real estate capital additions, such as computer software, computer equipment, and furniture and fixtures and leasehold improvements to the Company’s property management offices and its corporate offices, were approximately $0.7 million.  The Company expects to fund approximately $2.5 million in total non-real estate capital additions for the remainder of 2017.  These anticipated fundings represent a decrease over 2016, which is primarily driven by the substantial completion of the implementation of new systems during 2016.  The above assumption is based on current expectations and is forward-looking.

Capital expenditures to real estate and non-real estate capital additions are generally funded from net cash provided by operating activities and from investment cash flow.

Derivative Instruments

In the normal course of business, the Company is exposed to the effect of interest rate changes.  The Company seeks to manage these risks by following established risk management policies and procedures including the use of derivatives to hedge interest rate risk on debt instruments.  The Company may also use derivatives to manage commodity prices in the daily operations of the business.

The Company has a policy of only entering into contracts with major financial institutions based upon their credit ratings and other factors.  When viewed in conjunction with the underlying and offsetting exposure that the derivatives are designed to hedge, the Company has not sustained a material loss from these instruments nor does it anticipate any material adverse effect on its net income or financial position in the future from the use of derivatives it currently has in place.

58

See Note 9 in the Notes to Consolidated Financial Statements for additional discussion of derivative instruments at June 30, 2017.

Other

Total distributions paid in July 2017 amounted to $191.7 million (excluding distributions on Partially Owned Properties), which included certain distributions declared during the second quarter ended June 30, 2017.

Off-Balance Sheet Arrangements and Contractual Obligations

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 operating and/or other activities.  See Notes 2 and 6 in the Notes to Consolidated Financial Statements for additional discussion regarding the Company’s investments in partially owned entities.  See also Note 12 in the Notes to Consolidated Financial Statements for discussion regarding the Company’s development projects.

The Company’s contractual obligations for the next five years and thereafter have not changed materially from the amounts and disclosures included in the Company’s and the Operating Partnership’s Annual Report on Form 10-K for the year ended December 31, 2016.  See the updated debt maturity schedule included in Liquidity and Capital Resources for further discussion.

Critical Accounting Policies and Estimates

The Company’s and the Operating Partnership’s critical accounting policies and estimates have not changed materially from the information included in the Company’s and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2016.

(1) The National Association of Real Estate Investment Trusts (“NAREIT”) defines funds from operations (“FFO”) (April 2002 White Paper) as net income (computed in accordance with accounting principles generally accepted in the United States (“GAAP”)), excluding gains (or losses) from sales and impairment write-downs of depreciable operating properties, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.  Adjustments for unconsolidated partnerships and joint ventures will be calculated to reflect funds from operations on the same basis.  The April 2002 White Paper states that gain or loss on sales of property is excluded from FFO for previously depreciated operating properties only.  

(2) Normalized funds from operations (“Normalized FFO”) begins with FFO and excludes:

• the impact of any expenses relating to non-operating asset impairment and valuation allowances;

• pursuit cost write-offs;

• gains and losses from early debt extinguishment, including prepayment penalties, preferred share/preference unit redemptions and the cost related to the implied option value of non-cash convertible debt discounts;

• gains and losses on the sales of non-operating assets, including gains and losses from land parcel sales, net of the effect of income tax benefits or expenses; and

• other miscellaneous items.

60

(3) The Company believes that FFO and FFO available to Common Shares and Units / Units are helpful to investors as supplemental measures of the operating performance of a real estate company, because they are recognized measures of performance by the real estate industry and by excluding gains or losses related to dispositions of depreciable property and excluding real estate depreciation (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO and FFO available to Common Shares and Units / Units can help compare the operating performance of a company’s real estate between periods or as compared to different companies.  The Company also believes that Normalized FFO and Normalized FFO available to Common Shares and Units / Units are helpful to investors as supplemental measures of the operating performance of a real estate company because they allow investors to compare the Company's operating performance to its performance in prior reporting periods and to the operating performance of other real estate companies without the effect of items that by their nature are not comparable from period to period and tend to obscure the Company's actual operating results.  FFO, FFO available to Common Shares and Units / Units, Normalized FFO and Normalized FFO available to Common Shares and Units / Units do not represent net income, net income available to Common Shares / Units or net cash flows from operating activities in accordance with GAAP.  Therefore, FFO, FFO available to Common Shares and Units / Units, Normalized FFO and Normalized FFO available to Common Shares and Units / Units should not be exclusively considered as alternatives to net income, net income available to Common Shares / Units or net cash flows from operating activities as determined by GAAP or as a measure of liquidity.  The Company's calculation of FFO, FFO available to Common Shares and Units / Units, Normalized FFO and Normalized FFO available to Common Shares and Units / Units may differ from other real estate companies due to, among other items, variations in cost capitalization policies for capital expenditures and, accordingly, may not be comparable to such other real estate companies.  

(4) FFO available to Common Shares and Units / Units and Normalized FFO available to Common Shares and Units / Units are calculated on a basis consistent with net income available to Common Shares / Units and reflects adjustments to net income for preferred distributions and premiums on redemption of preferred shares/preference units in accordance with GAAP.  The equity positions of various individuals and entities that contributed their properties to the Operating Partnership in exchange for OP Units are collectively referred to as the "Noncontrolling Interests –Operating Partnership".  Subject to certain restrictions, the Noncontrolling Interests –Operating Partnership may exchange their OP Units for Common Shares on a one-for-one basis.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

The Company’s and the Operating Partnership’s market risk has not changed materially from the amounts and information reported in Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk, to the Company’s and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2016.  See the Current Environment section of Item 2.

Exhibit 10.1

AGE 62 RETIREMENT AGREEMENT

This Age 62 Retirement Agreement (this “Agreement”) is entered into by and between Equity Residential (“Equity” or the “Company”) and Bruce C. Strohm (“Executive”) as of June 21, 2017.

Witnesseth

Whereas, Executive is currently an officer of Equity and an employee of an Equity affiliate; and

Whereas, Executive has elected to voluntarily retire, effective 12:01 AM on January 1, 2018, (the “Retirement Date”), in accordance with the age 62 retirement provisions of Equity’s Share Incentive Plans relating to hires prior to 2009, after which he will no longer will be an officer or employee; and

Whereas, Executive and Equity wish to memorialize certain terms and conditions relating to Executive’s retirement;

NOW, THEREFORE, in consideration of the mutual covenants and promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Equity and Executive voluntarily and knowingly agree as follows:

1. For the purposes of this Agreement, the term “Equity” includes:  Equity Residential, Equity Residential Management, L.L.C., Equity Residential Services, L.L.C., Equity Residential Properties Management Limited Partnership, ERP Operating Limited Partnership, Equity Residential Properties Management Limited Partnership II, Equity Residential Properties Management Corp., Equity Residential Properties Management Corp.

    b. Pursuant to the Executive Retirement Benefits Agreement entered into by Executive and Equity Residential in February 2001, Equity will continue to provide Executive, his spouse and eligible dependents with company sponsored medical, dental and vision health insurance benefits and life insurance benefits, (initially at the same amount of coverage in existence as of the Retirement Date) for the period from the Retirement Date until Executive’s death, subject to the same terms and conditions (including making the same monthly contributions as existing employees) as are applicable to active full-time Equity employees.  The Company sponsored life insurance shall be subject to the provider’s standard age reduction schedule for active full-time employees, and Equity will not provide Executive with any disability or accidental death or dismemberment benefits after the Retirement Date.  Also, from and after the date that the Executive (and/or the Executive’s spouse, as applicable) becomes eligible for Medicare (typically the age of 65), the Executive (and/or his spouse, as applicable) is required to enroll in Medicare Parts A & B, and Medicare will be such individual’s primary insurer (and Equity’s plan will be secondary).  Equity will credit the Executive for the amount the Executive pays for Medicare Part B on behalf of himself (and/or his spouse) against the monthly contributions the Executive would otherwise pay for coverage under the Equity plan.  Equity’s obligations to provide Executive with the benefits hereunder shall survive any sale of Equity and/or its discontinuation of any such company sponsored plans and shall be binding on its successors and assigns, in which case Equity and/or its successors and assigns shall remain obligated to provide Executive with similar benefits as offered from time to time by other large public company sponsored health and life insurance plans.  Executive acknowledges that the value of Equity’s cost of providing insurance to Executive and his spouse as described in this paragraph may be taxable to Executive.  

    c. Effective on the Retirement Date, Executive will be fully vested in the split dollar life insurance policies purchased by Equity on his behalf in December, 1997, and any cash surrender value applicable thereto.  At the Retirement Date, Equity will release its collateral assignment of such policies, thereby releasing its right to receive any portion of the life insurance benefits and premiums paid by Equity. The cash surrender value may be taxable to Executive, in which case applicable withholdings and other required deductions will be made.

    d. Executive agrees that after the Retirement Date, and upon request, he will cooperate with and assist Equity from time to time in the investigation and defense of claims brought by or against Equity, and Equity shall reasonably compensate Executive for his time and efforts.  

8. Executive agrees not to make false or disparaging remarks about Equity or any Equity executive officer or trustee.

9. Executive acknowledges that in his capacity as an Equity officer and employee, he has obtained or had revealed to him a great deal of information of the utmost confidentiality, including but not limited to information of a personal nature about present and former employees of Equity, Equity’s internal policies and procedures, Equity’s financial performance and condition, and Equity’s business plans and strategies. Executive further understands and acknowledges that some of this information (“Confidential Information”) is protected from disclosure by the attorney/client privilege, self-critical analysis privilege or other legally recognized privilege.  Executive therefore agrees that at no time, unless he has obtained prior written consent from Equity’s General Counsel, will he use for his benefit or the benefit of any third party, or disclose to anyone, any Confidential Information.  Executive further agrees that if he is uncertain as to whether particular information is subject to the prohibitions of this paragraph, he will consult with Equity’s General Counsel before using or disclosing such information.   The term “Confidential Information” as used in this paragraph does not include information which (i) is or has become a matter of public record other than by way of an unauthorized disclosure by Executive; (ii) is generally known in the multi-family residential industry; (iii) is non-privileged and has been disclosed by Equity to people outside the Equity organization; or (iv) is required to be disclosed by law.  Executive agrees to immediately notify Equity’s General Counsel in the event he is contacted by any party (including, without limitation, process servers) seeking to institute or associate Executive with legal proceedings that involve Equity or Executive’s service at Equity.  As an attorney who has provided legal services to Equity, Executive agrees that if in the course of any legal proceedings it becomes reasonably appropriate for him to assert attorney-client privilege or similar confidentiality obligations in connection with his legal representation of Equity, Executive shall do so.

10. Executive acknowledges and agrees that due to the uniqueness of his services and confidential nature of the Confidential Information he possesses, the covenants set forth herein are reasonable and necessary for the protection of the legitimate business interests of Equity.

11. Except as provided below, Executive hereby fully, finally, and unconditionally releases Equity from any and all claims, suits, demands, charges, debts, grievances, costs, attorneys’ fees or injuries of every kind or nature, whether known or unknown, absolute or contingent, suspected or unsuspected, which Executive had or now has against Equity based on any matter or thing occurring or arising prior to the date of this Agreement, including but not limited to claims arising out of or relating to Executive’s employment with Equity or the separation of Executive’s employment from Equity.  This release includes, but is not limited to, claims for breach of any implied or express employment contract, wrongful discharge or layoff, constructive discharge, retaliatory discharge, defamation, intentional or negligent infliction of emotional distress, invasion of privacy, negligence, impairment of economic opportunity or other common law matters; claims for wages, bonuses or other compensation; and claims of any constitutional right or discrimination based on age, color, concerted activity, disability, marital status, national origin, parental status, race, religion, retaliation, sex, sexual orientation, source of income or veteran’s status, including but not limited to claims arising under Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1991, the Americans With Disabilities Act, the Age Discrimination In Employment Act Of 1967, the Older Workers Benefit Protection Act, the

Executive Retirement Income Security Act, the Equal Pay Act, the Family And Medical Leave Act, and any amendments to any of these statutes, as well as any other state and local statutes and ordinances prohibiting discrimination in employment, including but not limited to the laws of the states of  Illinois and any other state or locale in which Equity conducts business.  Executive further waives any right to monetary recovery should any administrative agency pursue any released claim on Executive’s behalf.  If for any reason any such agency takes the position that a pending charge has been brought on Executive’s behalf or encompasses Executive, Executive agrees to immediately advise the agency in writing that he does not wish to be involved in the matter and that the agency should terminate all efforts on Executive’s behalf, all claims having been fully and fairly satisfied by this Agreement.    Nothing in this paragraph shall affect or be deemed to compromise Executive’s rights or remedies under any Equity benefit plan or compensation program in which he participates, including but not limited to the Supplemental Executive Retirement Plan, Advantage Retirement Plan (“401K”), Executive Long-Term Incentive Plan, provisions of the limited partnership agreement of ERP Operating Limited Partnership relating to LTIP Units, and the 2011 Share Incentive Plan.  Also excluded from this release are any claims or administrative charges which cannot be waived by law, claims relating to enforcement of the Agreement, and claims for indemnification arising under law, by-laws or contract.  EXECUTIVE UNDERSTANDS AND AGREES THAT THIS RELEASE FOREVER BARS EXECUTIVE FROM SUING, ARBITRATING OR OTHERWISE ASSERTING A CLAIM AGAINST EQUITY ON ANY RELEASED CLAIM.

12. It is expressly understood by Executive and Equity that, Equity does not, in any way, either directly or indirectly, by inference or otherwise, admit to any liability or wrongdoing, to any violation under any law, statute, regulation, ordinance or contract or waive defenses as to those matters within the scope of this Agreement and that no court, agency, or arbitrator has found Equity so liable or to have committed any such violation.

13. Not later than 90 days following the Retirement Date, Executive shall submit a final travel and expense report to Equity itemizing all outstanding travel and business expenses which have not been previously reimbursed.  The report will include all information and supporting documentation normally provided under Equity’s practices and procedures. Equity shall promptly reimburse Executive for any such reimbursable expenses.

14. As a condition to the receipt of the payments and other benefits described in this Agreement, except those to be provided before the Retirement Date or otherwise required by law, Executive agrees that within twenty-one (21) days after the Retirement Date, he will sign and be bound by the original of the General Release and Waiver Agreement attached to this Agreement as Exhibit A, such release to be provided to Executive on or about the Retirement Date.

15. This Agreement sets forth all of the terms and conditions of the agreement between the parties on the matters set forth in this Agreement and shall be considered and understood to be a contractual commitment and not a mere recital.  This Agreement shall be binding upon Equity and its successors and assigns and upon Executive and his agents, heirs, executors, representatives and assigns (including spouse and eligible dependents as applicable hereunder).  Each party shall bear and pay his or its own costs and attorneys’ fees with regard to the negotiations involved with entering into this Agreement.

16. A waiver of any right under this Agreement must be in writing to be effective.  If any portion of this Agreement is held invalid by operation of law, the remaining terms of this Agreement shall not be affected.  The language of all parts of this Agreement shall in all cases be construed as a whole, according to its fair meaning, and not strictly for or against either of the parties.  This Agreement shall be governed by and construed in accordance with the laws of the State of Illinois, (without giving effect to the conflict of laws principles thereof) except to the extent federal laws apply.

17. Equity and Executive agree that notwithstanding any other agreement between Equity and Executive, any claim, lawsuit, arbitration or other litigation directly or indirectly arising from or related to this Agreement shall be instituted exclusively in the courts of Cook County, Illinois.  In the event of a breach by either party of any term of this Agreement, in addition to injunctive relief or any other damages, the non-breaching party may recover all costs and expense reasonably incurred by it in enforcing this Agreement or defending against a suit brought in violation of this Agreement, including reasonable attorneys’ fees.

18. Executive acknowledges that this Agreement constitutes written notice from Equity that it advises Executive to seek legal counsel before signing this Agreement, and that he has had an opportunity to do so.

19. In case any one or more of the provisions contained in this Agreement shall, for any reason under the laws of the jurisdiction, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability under the laws of such jurisdiction shall not affect any other provisions of this Agreement, but this Agreement shall be construed to minimize the effect of such invalid, illegal or unenforceable provision and to give the greatest effect to the transactions contemplated by this Agreement; provided, however, that any such invalidity, illegality or unenforceability in any jurisdiction shall not invalidate such provision in any other jurisdiction.

20. This Agreement cannot be modified, withdrawn, rescinded or supplemented in any manner after the date upon which it is executed except in a writing signed by both parties.  Executive acknowledges that in executing this Agreement he does not rely on any inducements, promises or representations made by Equity other than those expressly stated herein.  Executive further declares that he has read this Agreement and fully understands its terms and contents, including his rights and obligations hereunder, and freely, voluntarily and without coercion enters into this Agreement.

In Witness Whereof, this Agreement has been executed as of the above date.

ARTICLE 1INTRODUCTION

1.1Purpose of Plan

EQR initially adopted the Plan to provide a means by which certain employees could elect to defer receipt of portions of their Compensation and to provide opportunities for such individuals to save for retirement.  This Plan shall apply to amounts which were not earned and vested as of December 31, 2004 and are therefore subject to Code Section 409A.  Amounts which were earned and vested as of December 31, 2004 shall remain subject to the terms of a separate plan, The Equity Residential Grandfathered Supplemental Executive Retirement Plan.  Except as otherwise indicated, the provisions of this Plan as amended and restated in this document are effective April 1, 2017 and apply only to Elective Deferrals and Share Deferrals made on or after that date and all Accounts which have not been fully distributed.  Prior deferrals and prior distribution elections are subject to the provisions of the Plan in effect at the time of the deferral or distribution election.

1.2Status of Plan

Except with respect to the participation of Eligible Trustees, it is intended that the Plan be "a plan which is unfunded and is maintained by an employer primarily for the purpose of providing deferred compensation for a select group of management or "highly compensated employees" within the meaning of Sections 201(2), 301(a)(3) and 401(a)(1) of ERISA, and that the Plan be interpreted and administered consistent with that intent.  The Plan is also intended to comply in all respects with Code Section 409A and it is intended that the Plan be interpreted consistent with that intent.

1.3Good Faith Compliance

Notwithstanding anything in this Plan to the contrary, EQR may permit a Participant to take an action prior to December 31, 2008 inconsistent with this Plan so long as such action is either:  (i) permitted under the transitional rules contained in Treasury Regulations and other guidance issued pursuant to Code Section 409A, or (ii) is otherwise consistent with a reasonable good faith interpretation of Code Section 409A.

4.1Elective Deferrals of Compensation

(a)An individual who is an Eligible Employee or Eligible Trustee may elect to defer receipt of a whole percentage or whole dollar amount of up to 25% (or 100% in the case of an Eligible Trustee) of the Compensation (exclusive of any Incentive Pay) otherwise payable to him or her, on and after a subsequent Entry Date for the applicable Plan Year.  In addition, subject to the provisions of subsection (b) (iii) below, an Eligible Employee may elect to defer up to 100% of any Incentive Pay payable during a Plan Year.  Also, an Eligible Employee may separately elect to defer from his salary in any Plan Year, an amount equal up to 100% of the elective deferrals refunded to such Eligible Employee from the Equity Residential Advantage

QB\5950970.23 5

Retirement Savings Plan during such Plan Year.  An Eligible Employee or Eligible Trustee who desires to elect such a deferral shall complete and submit an Enrollment Form (in writing or electronically) with the Plan Administrator.

(b)Each Enrollment Form shall be effective as described in clauses (i), (ii), (iii) or (iv) below.

(i) An Enrollment Form with respect to salary and commissions paid from and after the Entry Date shall be submitted on or before a deadline established by the Plan Administrator, but in no event later than the date that precedes such Entry Date.

(ii) Notwithstanding clause (i), in the case of a Participant's Initial Entry Date, the Enrollment Form will be effective with respect to salary and commissions received for services performed after the Enrollment Form is submitted, if it is filed within 30 days after the Participant's Initial Entry Date.

(iii) An Enrollment Form with respect to Incentive Pay which qualifies as Performance Based Compensation (including, without limitation, with respect to the Development Incentive Plan) shall be submitted on or before a deadline established by the Plan Administrator, but in no event later than:  (i) with respect to Performance Based Compensation which is earned over a predefined performance period, the date which is six months prior to the end of the predefined performance period; or (ii) with respect to Performance Based Compensation which is not earned over a pre-defined performance period, a date determined by the Plan Administrator which is at least six months prior to the end of the performance period in which the Performance Based Compensation is earned.  An enrollment form with respect to Incentive Pay which does not qualify as Performance Based Compensation, shall be submitted before the first day of the performance period on which the Incentive Pay is based.  

(iv) An Enrollment Form with respect to elective deferrals refunded to such Eligible Employee from the Equity Residential Advantage Retirement Savings Plan shall be submitted before January 1 of the Plan Year in which the elective deferrals from the Equity Residential Advantage Retirement Savings Plan are refunded.  Deferrals pursuant to this provision shall be made from salary paid in April of the Plan Year in which the elective deferrals under the Equity Residential Retirement Savings Plan are refunded.  The Employer may, in its sole discretion, spread the deferrals over more than one pay cycle.

QB\5950970.23 6

(c)Each Enrollment Form shall be effective for all Compensation to which such Enrollment Form applies.  At the Plan Administrator’s discretion, an election to defer salary or commissions also shall apply from and after subsequent Entry Dates unless changed as provided herein, or until such time (if any) that the Participant is suspended from making Elective Deferrals or Share Deferrals pursuant to the Plan, as provided under Section 3.3.

(d)A Participant’s Enrollment Form shall designate the whole percentage or whole dollar amount of such Participant’s Compensation deferrals to be credited to one or more of the Participant’s Retirement Sub-Accounts or to one or more of the Participant’s In-Service Sub-Accounts.  New Sub-Accounts shall be established based on Participant Enrollment Forms and shall be effective with respect to Compensation to which such Enrollment Forms apply.  At the Plan Administrator’s discretion, in the absence of a specific designation of the applicable Sub-Account, the Compensation deferrals shall be allocated to the Sub-Accounts designated in the last valid election.  Unless the Plan Administrator handles otherwise, deferral of salary equal to the elective deferrals refunded from the Equity Residential Advantage Retirement Savings Plan shall be credited to the same Sub-Accounts in the same proportions as other elective salary deferrals.  

4.2Share Deferrals

(a)An individual who is an Eligible Employee or Eligible Trustee and who is to receive a grant of a Restricted Share may elect to defer, with respect to a Restricted Share, the ownership of the Share.  An Eligible Employee or Eligible Trustee who desires to elect a Share Deferral shall complete and file an Enrollment Form with the Plan Administrator.  

(b)An election pursuant to paragraph (a) with respect to Restricted Shares which are Performance-Based Compensation but are not vested based on performance criteria must be made at least six months prior to the end of the performance period on which the award grant is based.  If said Restricted Shares are subject to vesting based on performance criteria such election shall be made at least six months prior to the end of the performance period on which the vesting is based.  

(c)Notwithstanding the foregoing provisions of this Section 4.2, the Participant's Account shall not hold any Restricted Share deferred by the Participant in accordance with paragraph (a) above.  Instead, the Plan Administrator shall credit to the Participant's Account an amount equal to the number of Share Units equal to the number of Restricted Shares that would otherwise be received by the Participant.  Notwithstanding the foregoing, the Funding Trustee may hold Shares.

(d)An Enrollment Form for an election pursuant to paragraph (a) shall designate whether the Restricted Shares deferred by the Participant shall be credited to one or more of the Participant’s Retirement Sub-Accounts or to one or more of the Participant’s In-Service Sub-Accounts and in what percentage.  New Sub-Accounts shall be established based on Participant Enrollment Forms and shall be effective with respect to the Restricted Shares to which such Enrollment Form applies. At the Plan Administrator’s discretion, in the absence of a specific designation of the applicable Sub-Account, the deferrals shall be allocated to the Sub-Accounts designated in the last valid elections with respect to Share Deferrals.

QB\5950970.23 7

(e)With respect to dividend equivalents relating to Shares subject to a Share Deferral election made pursuant to paragraph (a), the Enrollment Form for such Share Deferral shall automatically be deemed an election by the Participant to:  (i) not defer distribution of any dividend equivalents from the subject Shares prior to vesting; and (ii) defer distribution of dividend equivalents from the subject Shares at and following vesting.  The deferral of such dividend equivalents shall be allocated to the Sub-Account(s) designated for the related Shares.  Notwithstanding the foregoing, Participants making a Share Deferral election with respect to Shares granted under EQR's Long Term Incentive Plan for executives may, at the Plan Administrator's discretion, make deferral elections with respect to related dividend equivalents that are different than the automatic elections described in this paragraph (e).

4.3Enrollment Forms

All Enrollment Forms submitted pursuant to Article 4 shall be irrevocable (i) with respect to Elective Deferrals under Section 4.1, and (ii) for Share Deferrals under Section 4.2, with respect to the Restricted Shares subject thereto.  Notwithstanding the foregoing, if an Unforeseeable Emergency occurs with respect to a Participant, he or she may revoke his or her Enrollment Form (but only to the extent reasonably needed to relieve the Unforeseeable Emergency) and only prospectively.  

4.4Employer Contribution.

Employer Contributions may be made at any time in the Employer’s sole discretion.  Such Employer Contributions shall be allocated to the Accounts and Sub-Accounts of Eligible Employees in the amounts determined by the Employer in its sole discretion and shall be subject to such vesting, distribution and other rules as are determined by the Employer in its sole discretion.

ARTICLE 5
ACCOUNTS

5.1Accounts

The Plan Administrator shall establish an Account and such Sub-Accounts as are appropriate for each Participant reflecting Elective Deferrals, Share Deferrals and Employer Contributions credited to the Participant together with any adjustments for income, gain or loss and any payments from the Account.  Elective Deferrals will be credited to the Account and Sub-Accounts of each applicable Participant as of the later of the date they are received by the Funding Trustee or the date the Funding Trustee receives from the Plan Administrator such instructions as the Funding Trustee may reasonably require to allocate the amount received among the investments maintained by the Funding Trustee.  Share Units attributable to Share Deferrals will be credited to the Account and Sub-Accounts of the Participant on the date a Restricted Share is granted.  Employer Contributions shall be credited in the manner determined by the Employer.  As soon as practicable following the last business day of each calendar quarter, the Plan Administrator (or its designee) shall provide the Participant with a statement of such Participant's Account reflecting the income, gains and losses (realized and unrealized), amounts of deferrals and distributions with respect to such Account since the prior statement, provided that such statement may reflect Share Units relating to unvested Shares to the extent reasonably practicable.  

QB\5950970.23 8

5.2Investments

(a)The assets of the Funding Trust shall be invested in such investments, including Shares, as the Funding Trustee shall determine.  The Funding Trustee may (but is not required to) consider the Employer's or a Participant's investment preferences when investing such assets including that the Funding Trustee hold mutual funds (load or no-load).

(b)Expense charges for transactions performed at the request of each Participant shall be paid from each respective Participant’s Account and will be listed on the quarterly statement for such Account.  Other Plan charges and administrative expenses may be paid by the Employer or by the Participant if disclosed to the Participant in advance.

(c)Notwithstanding anything in this Section 5.2 to the contrary, a Participant who elects to defer Restricted Shares and is credited with Share Units in such Participant’s Account shall be prohibited from converting his or her Share Units to any other investment and all Share Units held in a Participant's Account shall be distributed in kind as Shares, subject to the terms of Article 7 hereof.

(d)Subject to paragraph (a) above, a Participant may request that different Sub-Accounts reflect the Funding Trust’s investment in different mutual funds or other investments.

ARTICLE 6
VESTING

Except as otherwise provided with respect to an Employer Contribution and subject to the actual vesting terms of grants of Restricted Shares, a Participant shall at all times have a fully vested and non-forfeitable right to all Elective Deferrals and Share Deferrals credited to his or her Account, adjusted for income, gain and loss attributable thereto.

ARTICLE 7
PAYMENTS

7.1Election as to Time and Form of Payment

(a)Subject to the limitations of this Article 7, a Participant may specify on the Participant's Enrollment Form the distribution date at which each of the Participant's Sub-Accounts will be paid or commence to be paid to the Participant.  Such commencement date for the Participant’s Retirement Sub-Accounts may be the Participant's Separation from Service or in any January following the Participant's Separation from Service.

(b)The Participant's election with respect to the distribution of each of the Participant’s Retirement Sub-Accounts under this Section 7.1 may provide for payments to be made in the form of:

(i) A single lump-sum payment;

QB\5950970.23 9

(ii) Annual installments over a period elected by the Participant of up to ten (10) years, the amount of each installment to equal the then balance of the Sub-Account divided by the number of installments remaining to be paid; or

(iii) a combination of (i) and (ii).  

All distributions must be completed within ten (10) years of the Participant's Separation from Service.  To the extent that a Restricted Share vests after a Participant’s Separation from Service, the Participant shall receive the portion of the Participant’s Account attributable to such Restricted Share on the later of the date such amount would otherwise be paid or the date such Restricted Share vests.

(c)A Participant may elect to distribute an In-Service Sub-Account under this Section 7 in any Plan Year which is at least two years after the year in which deferrals are first made to such Sub-Account.  Distribution of any Participant’s In-Service Sub-Account under this Section 7 shall be made at the Participant’s election in a lump sum or in installments over a period of up to 4 years during a calendar month determined by the Plan Administrator.  Notwithstanding any election made pursuant to this Section 7 (but subject to Section 7.1(g) in the case of a Specified Employee) upon Separation from Service all In-Service Sub-Accounts, other than those payable in installments where installment payments have already commenced prior to Separation from Service, shall be distributed in the manner specified in the most recent distribution election form executed with respect to the initial Retirement Sub-Account of the Participant.

(d)A Participant may change a date and/or form elected for distribution pursuant to paragraphs (a), (b) and (c); provided that (i) the change is filed with the Plan Administrator at least one year before the date on which the previously elected distribution date occurs; (ii) the new distribution date and/or form does not take effect for a year after the new election is made; and (iii) the first distribution under the new election occurs no earlier than 5 years after the date on which the distribution would otherwise have occurred.

(e)Except as provided in Sections 7.2, 7.3 and 7.4, payments from a Participant's Account shall be made in accordance with the Participant's elections under this Section 7.1.  If no election is made by a Participant with respect to all or a part of a Participant's Deferrals, or an election is invalid, distribution shall be made in a single lump sum upon the Participant's Separation from Service.

(f)Payments from a Participant's Account shall be in cash or in kind (comprising assets of the Funding Trust), as determined by the Funding Trustee except that all Share Units held in a Participant's Account shall be distributed in Shares.  The Funding Trustee may (but is not required to) consider the Employer's or a Participant's preferences when determining the form in which payment is made from the Participant's Account.

QB\5950970.23 10

(g)Notwithstanding any provision of this Plan to the contrary, no payments to a Specified Employee shall be made during the 6 months after such Specified Employee's Separation from Service unless the Separation from Service is due to death.  Any payments delayed pursuant to this Section 7.1(g) shall be paid immediately following the end of such 6 month period.

(h)Notwithstanding any provision in this Plan to the contrary, if the Participant's Account is less than the applicable dollar amount under Code Section 402(g) at the time of the Participant's Separation from Service, the Participant shall receive the value of his or her Account in the form of a lump sum distribution.

7.2Separation from Service

Upon a Participant's Separation from Service for any reason other than death, the vested portion of the Participant's Account shall be paid to the Participant according to the Participant's distribution election made in accordance with the Plan.  

7.3Death

(a)If a Participant dies prior to the complete distribution of his or her Account, the vested portion of the Participant's Account shall be paid to the Participant's designated beneficiary or beneficiaries, according to the Participant's distribution elections made in accordance with the Plan, which election may provide that distributions are accelerated in the event of the Participant's death.  To the extent distributions are accelerated, the beneficiary or beneficiaries may elect to receive the distributions in the calendar year of the Participant's death (if administratively feasible) or in the subsequent calendar year.

(b)A Participant may designate a beneficiary by notifying the Plan Administrator in writing, at any time before Participant's death, on a form prescribed by the Plan Administrator for that purpose.  A Participant may revoke any beneficiary designation or designate a new beneficiary at any time without the consent of a beneficiary or any other person.  If no beneficiary is designated or no designated beneficiary survives the Participant, payment shall be made to the Participant's surviving spouse, or, if none, to the Participant's issue per stirpes, in accordance with the Participant's distribution election.  If no spouse or issue survives the Participant, payment shall be made in a single payment to the Participant's estate.

7.4Withdrawal Due to Unforeseeable Emergency

If a Participant experiences an Unforeseeable Emergency, the Plan Administrator, in its sole discretion, may pay to the Participant only that portion, if any, of the vested portion of such Participant's Account which the Plan Administrator determines is necessary to satisfy the emergency need, including any amounts necessary to pay any federal, state or local income taxes reasonably anticipated to result from the distribution.  A Participant requesting an emergency payment shall apply for the payment in writing using a form prescribed by the Plan Administrator for that purpose and shall provide such additional information as the Plan Administrator may require including the Sub-Account from which the distribution is to be made.  

QB\5950970.23 11

8.4Indemnification of Plan Administrator

EQR agrees to indemnify and to defend to the fullest extent permitted by law any officer(s) or employee(s) who serve as Plan Administrator (including any such individual who formerly served as Plan Administrator) against all liabilities, damages, costs and expenses (including reasonable attorneys' fees and amounts paid in settlement of any claims approved by EQR in writing in advance) occasioned by any act or omission to act in connection with the Plan, if such act or omission is in good faith.

ARTICLE 9
CLAIMS PROCEDURES

A Participant, beneficiary or an authorized representative (a "claimant") shall make all claims for benefits under the Plan in writing addressed to the Plan Administrator at the address of EQR.  Each claim shall be reviewed by the Plan Administrator within a reasonable time after it is submitted, but in no event longer than ninety (90) days after it is received by the Plan Administrator.  If a claim is wholly or partially denied, the claimant shall be sent written notice of such fact.  If a decision on a claim cannot be rendered by the Plan Administrator within the ninety (90) day period, the Plan Administrator may extend the period in which to render the decision up to one hundred eighty (180) days after receipt of the written claim.  The denial notice, which shall be written in a manner calculated to be understood by the claimant, shall contain (a) the specific reason(s) for the adverse determination, (b) reference to the specific Plan provisions on which the adverse determination is based, (c) a description of any additional material information necessary for the claim to be granted and an explanation of why such information is necessary, and (d) a description of the Plan's claim review procedures, the time limits under the procedures and a statement regarding the claimant's right to bring a civil action under Section 502(a) of the Employee Retirement Income Security Act of 1974 ("ERISA") following an adverse benefit determination on appeal.

Within sixty (60) days after receipt by the claimant of written notice of the denial, the claimant or his duly authorized representative may appeal such denial by filing a written application for review with the Plan Administrator at the address of EQR.  Each such application shall state the grounds upon which the claimant seeks to have the claim reviewed.  The claimant or his representative may request access to all pertinent documents relative to the claim for the purpose of preparing the application.  The Plan Administrator will then review the decision and notify the claimant in writing of the result within sixty (60) days of receipt of the application for review.  The sixty (60) day period may be extended if specific circumstances require an extension of time for processing, in which case the decision shall be rendered as soon as possible, but no later than one hundred twenty (120) days after receipt of the application for review.  The appeal denial notice, which shall be written in a manner calculated to be understood by the claimant, shall contain (a) the specific reason or reasons for the adverse determination, (b) reference to the specific Plan provisions on which the adverse determination is based, (c) a statement that the claimant is entitled to receive, upon written request and free of charge, access to and copies of all documents, records and other information relevant to the benefit claim, and (d) a statement regarding the claimant's right to bring a civil action under Section 502(a) of ERISA following an adverse benefit determination on appeal.

QB\5950970.23 13

ARTICLE 10AMENDMENT AND TERMINATION

10.1Amendment

EQR shall have the right to amend the Plan from time to time, subject to Section 10.3 and 10.4, by an instrument in writing which has been executed on its behalf by a duly authorized officer.

10.2Termination of Plan

The Plan is strictly a voluntary undertaking on the part of the Employers and shall not be deemed to constitute a contract between an Employer and any Eligible Employee (or any other employee) or any Eligible Trustee, a consideration for, or an inducement or condition of employment for, the performance of the services by any Eligible Employee (or other employee) or any Eligible Trustee.  EQR reserves the right to terminate the Plan at any time, subject to Section 10.3, by an instrument in writing which has been executed on its behalf by a duly authorized officer.  Upon termination, EQR may (a) elect to continue to maintain the Funding Trust to pay benefits hereunder as they become due as if the Plan had not terminated or (b) direct the Funding Trustee to pay promptly to Participants (or their beneficiaries) the vested balance of their Accounts.  For purposes of the preceding sentence, in the event clause (b) is implemented, the Account balance of all Participants who are in the employ of an Employer at the time the Funding Trustee is directed to pay such balances shall become fully vested and nonforfeitable.  After Participants and their beneficiaries are paid all Plan benefits to which they are entitled, all remaining assets of the Funding Trust shall be returned to the Employers.

10.3Existing Rights

No amendment or termination of the Plan shall adversely affect the rights of any Participant with respect to amounts that have been credited to his or her Account prior to the date of such amendment or termination.

10.4409A

No amendment or termination of the Plan shall cause the Plan to violate Code Section 409A.

QB\5950970.23 14

ARTICLE 11MISCELLANEOUS

11.1No Funding

The Plan constitutes a mere promise by the Employers to make payments in accordance with the terms of the Plan and Participants and beneficiaries shall have the status of general unsecured creditors of the Employers.  Nothing in the Plan will be construed to give any employee or any other person rights to any specific assets of an Employer or of any other person.  In all events, it is the intent of the Employers that the Plan be treated as unfunded for tax purposes and for purposes of Title I of ERISA.  Subject to the foregoing, EQR shall establish and maintain a "rabbi" trust for the purpose of providing benefits under the terms of the Plan.

11.2Non-assignability

None of the benefits, payments, proceeds or claims of any Participant or beneficiary shall be subject to any claim of any creditor of any Participant or beneficiary and, in particular, the same shall not be subject to attachment or garnishment or other legal process by any creditor of such Participant or beneficiary, nor shall any Participant or beneficiary have any right to alienate, anticipate, commute, pledge, encumber or assign any of the benefits or payments or proceeds which he or she may expect to receive, contingently or otherwise under the Plan.

Notwithstanding the foregoing, a domestic relations order, as defined in Code Section 414(p)(1)(B), may provide that a Participant’s rights with respect to all or a part of the Participant's Account are transferred to an alternate payee.  Such domestic relations order may provide that payments to the alternate payee will be accelerated and that such payments will be paid in a different form than the form elected by the Participant, so long as the form is permitted by the Plan.

11.3Limitation of Participant's Rights

Nothing contained in the Plan shall confer upon any person a right to be employed or to continue in the employ of an Employer or on the Board of Trustees of EQR, or interfere in any way with the right of an Employer to terminate the employment of a Participant in the Plan at any time, with or without cause.

11.4Participants Bound

Any action with respect to the Plan taken by the Plan Administrator or the Funding Trustee or any action authorized by or taken at the direction of the Plan Administrator, an Employer or the Funding Trustee shall be conclusive upon all Participants and beneficiaries entitled to benefits under the Plan.

QB\5950970.23 15

11.5Receipt and Release

Any payment to any Participant or beneficiary in accordance with the provisions of the Plan shall, to the extent thereof, be in full satisfaction of all claims against the Employers, the Plan Administrator and the Funding Trustee under the Plan, and the Plan Administrator may require such Participant or beneficiary, as a condition precedent to such payment, to execute a receipt and release to such effect.  If any Participant or beneficiary is determined by the Plan Administrator to be incompetent by reason of physical or mental disability or age to give a valid receipt and release, the Plan Administrator may cause the payment or payments becoming due to such person to be made to another person for his or her benefit without responsibility on the part of the Plan Administrator, the Employers or the Funding Trustee to follow the application of such funds.

11.6Governing Law

The Plan shall be construed, administered, and governed in all respects under and by the laws of the State of Illinois to the extent not superseded by federal law.  If any provision shall be held by a court of competent jurisdiction to be invalid or unenforceable, the remaining provisions hereof shall continue to be fully effective.

11.7Headings and Subheadings

Headings and subheadings in this Plan are inserted for convenience only and are not to be considered in the construction of the provisions hereof.

(1) For the years ended December 31, 2016, 2015 and 2014, and the six months ended June 30, 2017 and 2016, the ratios have been increased primarily due to gains on the sales of real estate properties that were not included in discontinued operations as a result of the Company’s adoption of the new accounting standard effective January 1, 2014.

(2) For the year ended December 31, 2013, the coverage deficiency approximated $219.8 million.  All 2013 and prior year ratios have been reduced due to the disposition of properties which resulted in the inclusion of those properties in discontinued operations. The ratios have been further reduced due to non-cash depreciation expense and impairment charges and premiums on the redemption of Preferred Shares/Preference Units. The Company was in compliance with its unsecured public debt covenants for all periods presented.

Summary Of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.  In the opinion of management, all adjustments (consisting of normal recurring accruals) and certain reclassifications considered necessary for a fair presentation have been included.  Certain reclassifications have been made to the prior period financial statements in order to conform to the current year presentation.  These reclassifications did not have an impact on net income previously reported.  Operating results for the six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

In preparation of the Company’s financial statements in conformity with accounting principles generally accepted in the United States, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from these estimates.

The balance sheets at December 31, 2016 have been derived from the audited financial statements at that date but do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.

For further information, including definitions of capitalized terms not defined herein, refer to the consolidated financial statements and footnotes thereto included in the Company’s and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2016.

Income and Other Taxes

Due to the structure of EQR as a REIT and the nature of the operations of its operating properties, no provision for federal income taxes has been made at the EQR level.  In addition, ERPOP generally is not liable for federal income taxes as the partners recognize their proportionate share of income or loss in their tax returns; therefore no provision for federal income taxes has been made at the ERPOP level.  Historically, the Company has generally only incurred certain state and local income, excise and franchise taxes.  The Company has elected Taxable REIT Subsidiary (“TRS”) status for certain of its corporate subsidiaries and as a result, these entities will incur both federal and state income taxes on any taxable income of such entities after consideration of any net operating losses.

Deferred tax assets and liabilities applicable to the TRS are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.  These assets and liabilities are measured using enacted tax rates for which the temporary differences are expected to be recovered or settled.  The effects of changes in tax rates on deferred tax assets and liabilities are recognized in earnings in the period enacted.  The Company’s deferred tax assets are generally the result of tax affected suspended interest deductions, net operating losses, differing depreciable lives on capitalized assets and the timing of expense recognition for certain accrued liabilities.  As of June 30, 2017, the Company has recorded a deferred tax asset, which is fully offset by a valuation allowance due to the uncertainty of realization.  The Company currently anticipates electing REIT status for its primary TRS upon filing the 2016 tax return in the third quarter of 2017.  This election will be retroactive to January 1, 2016.

Recently Issued Accounting Pronouncements

InMay2014,theFinancialAccountingStandardsBoard(the"FASB")issuedacomprehensivenewrevenuerecognition standard entitled Revenue from Contracts with Customers that will supersede nearly all existing revenue recognition guidance.  Thenewstandardspecificallyexcludesleaserevenue.  Thenewstandard’scoreprincipleisthatacompanywillrecognizerevenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expectstobeentitledinexchangeforthosegoodsorservices.  Companieswilllikelyneedtousemorejudgmentandmakemore estimatesthanundercurrentrevenuerecognitionguidance.  Thesemayincludeidentifyingperformanceobligationsinthecontract, estimating the amount of variable consideration, if any, to include in the transaction price and allocating the transaction price to each separate performance obligation.  The new standard may be applied retrospectively to each prior period presented or prospectively with the cumulative effect, if any, recognized as of the date of adoption.  The Company anticipates selecting the modified retrospective transition method with a cumulative effect recognized as of the date of adoption and will adoptthenewstandardeffectiveJanuary1,2018, when effective.  TheCompanyiscontinuingtoevaluatethestandard;however,wedonotexpect itsadoptiontohaveasignificantimpactontheconsolidatedfinancialstatements,asinexcessof90%oftotalrevenuesconsistof rental income from leasing arrangements, which is specifically excluded from the standard.  In addition, the Company'sfee and assetmanagementactivitiesareimmaterialnowthatitsolditsinterestinJointBaseLewisMcChord in 2016andgiventhenatureofitsdispositiontransactions,thereshouldbenochangesinaccountingunderthenewstandard.

InJanuary2016,theFASBissuedanewstandardwhichrequirescompaniestomeasureallequitysecuritieswithreadily determinablefairvaluesatfairvalueonthebalancesheet,withchangesinfairvaluerecognizedinnetincome.  Thenewstandard will be effective for the Company beginning on January 1, 2018.  The Company does not expect that this will have a material effect on its consolidated results of operations or financialposition.

InFebruary2016,the FASB issued a new leases standard which sets out principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessors and lessees).  The new standard requires the following:

• Lessors – Leases will be accounted for using an approach that is substantially equivalent to existing guidance for operating, sales-type and financing leases, but aligned with the new revenue recognition standard.  Lessors will be required to allocate lease payments to separate lease and non-lease components of each lease agreement, with the non-lease components evaluated under the new revenue recognition standard.

• Lessees – Leases will be accounted for using a dual approach, classifying leases as either operating or finance based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee.  This classification will determine whether the lease expense is recognized on a straight-line basis over the term of the lease (for operating leases) or based on an effective interest method with a front-loaded expense recognition (for finance leases).  A lessee is also required to record a right-of-use asset and a lease liability on its balance sheet for all leases with a term of greater than 12 months regardless of their classification as operating or finance leases.  Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases.

The new standard will be effective for the Company beginning on January 1, 2019, with early adoption permitted, though the Company currently anticipates adopting the new standard on the effective date.  The new standard must be adopted using a modified retrospective method, which requires application of the new guidance at the beginning of the earliest comparative period presented and provides for certain practical expedients, which the Company currently anticipates electing.  The Company anticipates that its residential and retail/commercial leases where it is the lessor will continue to be accounted for as operating leases under the new standard.  Therefore, the Company does not currently anticipate significant changes in the accounting for its lease revenues.  The Company is also the lessee under various corporate office and ground leases, which it will be required to recognize right of use assets and related lease liabilities on its consolidated balance sheets upon adoption.  The Company currently anticipates that its corporate office leases where it is the lessee will continue to be accounted for as operating leases under the new standard.  Based on its anticipated election of the practical expedients, the Company would not be required to reassess the classification of existing ground leases and therefore these leases would continue to be accounted for as operating leases.  However, in the event we modify existing ground leases and/or enter into new ground leases after adoption of the new standard, such leases will likely be classified as finance leases.  The Company will continue to evaluate the impact of adopting the new leases standard on its consolidated results of operations and financial position.

In June 2016, the FASB issued a new standard which requires companies to adopt a new approach for estimating credit losses on certain types of financial instruments, such as trade and other receivables and loans.  The standard will require entities to estimate a lifetime expected credit loss for most financial instruments, including trade receivables.  The new standard will be effective for the Company beginning on January 1, 2020, with early adoption permitted beginning January 1, 2019.  TheCompanyiscurrentlyevaluatingtheimpactofadoptingthenewstandardonitsconsolidatedresultsofoperationsand financial position.

InAugust2016andOctober2016,theFASBissuednewstandardstoclarifyhowspecifictransactionsareclassifiedand presented on the statement of cash flows.  Among other clarifications, the new standards specifically provide guidance for the following items within the statement of cash flows which have required significant judgment in thepast:

• Cash payments related to debt prepayments or extinguishment costs are to be classified within financingactivities;

• The portion of the cash payment made to settle a zero-coupon bond or a bond with an insignificant cash coupon attributable to accreted interest related to a debt discount is to be classified as a cash outflow within operating activities, and the portion attributable to the principal is to be classified within financingactivities;

• Insurance settlement proceeds are to be classified based on the nature of theloss;

• Companies must elect to classify distributions received from equity method investees using either a cumulative earnings approach or a look-through approach and the election must be disclosed;and

• Restrictedcashwillbeincludedwithcashandcashequivalentsonthestatementofcashflows.  Totalcashandcash equivalents and restricted cash are to be reconciled to the related line items on the balancesheet.

Thenewstandardsmustbeappliedretrospectivelytoallperiodspresentedintheconsolidatedfinancialstatementsandtheywill beeffectivefortheCompanybeginningonJanuary1,2018,withearlyadoptionpermitted.  TheCompanyiscurrentlyevaluating the impact of adopting the new standards on its consolidated results of operations and financialposition.

InFebruary 2017,theFASB issuedanewstandardwhich clarifies the accounting treatment for partial sales of nonfinancial assets (i.e. real estate).  The standard clarifies that partial sales transactions include contributions of nonfinancial assets to a joint venture or other noncontrolled investee.  Companies must recognize a full gain or loss on transfers of nonfinancial assets to equity method investees.  The standard requires companies to derecognize distinct nonfinancial assets or distinct in substance nonfinancial assets in partial sale transactions when it does not have a controlling financial interest in the legal entity that holds the asset and transfers control of the asset.  Once the distinct nonfinancial asset is transferred, the company is required to measure any non-controlling interest it receives or retains at fair value and recognize a full gain or loss on the transaction.  If a company transfers ownership interests in a consolidated subsidiary and continues to maintain a controlling financial interest, the company does not derecognize the assets or liabilities, and accounts for the transaction as an equity transaction and no gain or loss is recognized. The new standard will be effective for the Company beginning on January 1, 2018 and early adoption was permitted beginning on January 1, 2017.  The Company anticipates adopting the new standard concurrently with the new revenue recognition standard.  The new standard may be applied retrospectively to each prior period presented or prospectively with the cumulative effect recognized as of the date of adoption.  The Company is currently evaluating the impact of adopting the new standard on its consolidated results of operations and financial position.

The Company is the controlling partner in various consolidated partnerships owning 17 properties and 3,215 apartment units having a noncontrolling interest book value of $6.3 million at June 30, 2017.  The Company is required to make certain disclosures regarding noncontrolling interests in consolidated limited-life subsidiaries.  Of the consolidated entities described above, the Company is the controlling partner in limited-life partnerships owning four properties having a noncontrolling interest deficit balance of $7.4 million.  These four partnership agreements contain provisions that require the partnerships to be liquidated through the sale of their assets upon reaching a date specified in each respective partnership agreement.  The Company, as controlling partner, has an obligation to cause the property owning partnerships to distribute the proceeds of liquidation to the Noncontrolling Interests in these Partially Owned Properties only to the extent that the net proceeds received by the partnerships from the sale of their assets warrant a distribution based on the partnership agreements.  As of June 30, 2017, the Company estimates the value of Noncontrolling Interest distributions for these four properties would have been approximately $64.4 million (“Settlement Value”) had the partnerships been liquidated.  This Settlement Value is based on estimated third party consideration realized by the partnerships upon disposition of the four Partially Owned Properties and is net of all other assets and liabilities, including yield maintenance on the mortgages encumbering the properties, that would have been due on June 30, 2017 had those mortgages been prepaid.  Due to, among other things, the inherent uncertainty in the sale of real estate assets, the amount of any potential distribution to the Noncontrolling Interests in the Company's Partially Owned Properties is subject to change.  To the extent that the partnerships' underlying assets are worth less than the underlying liabilities, the Company has no obligation to remit any consideration to the Noncontrolling Interests in these Partially Owned Properties.

The equity positions of various individuals and entities that contributed their properties to the Operating Partnership in exchange for OP Units, as well as the equity positions of the holders of restricted units, are collectively referred to as the “Noncontrolling Interests – Operating Partnership”.  Subject to certain exceptions (including the “book-up” requirements of restricted units), the Noncontrolling Interests – Operating Partnership may exchange their Units with EQR for Common Shares on a one-for-one basis.  The carrying value of the Noncontrolling Interests – Operating Partnership (including redeemable interests) is allocated based on the number of Noncontrolling Interests – Operating Partnership Units in total in proportion to the number of Noncontrolling Interests – Operating Partnership Units in total plus the number of Common Shares.  Net income is allocated to the Noncontrolling Interests – Operating Partnership based on the weighted average ownership percentage during the period.

The Operating Partnership has the right but not the obligation to make a cash payment instead of issuing Common Shares to any and all holders of Noncontrolling Interests – Operating Partnership Units requesting an exchange of their OP Units with EQR.  Once the Operating Partnership elects not to redeem the Noncontrolling Interests – Operating Partnership Units for cash, EQR is obligated to deliver Common Shares to the exchanging holder of the Noncontrolling Interests – Operating Partnership Units.

TheNoncontrollingInterests–OperatingPartnershipUnitsareclassifiedaseithermezzanineequityorpermanentequity.  If EQR is required, either by contract or securities law, to deliver registered Common Shares, such Noncontrolling Interests – Operating Partnership are differentiated and referred to as “Redeemable Noncontrolling Interests – Operating Partnership”.  Instruments that require settlement in registered shares cannot be classified in permanent equity as it is not always completely within an issuer’s control to deliver registered shares.  Therefore, settlement in cash is assumed and that responsibility for settlement in cash is deemed to fall to the Operating Partnership as the primary source of cash for EQR, resulting in presentation in the mezzanine section of the balance sheet.  The Redeemable Noncontrolling Interests – Operating Partnership are adjusted to the greater of carrying value or fair market value based on the Common Share price of EQR at the end of each respective reporting period.  EQR has the ability to deliver unregistered Common Shares for the remaining portion of the Noncontrolling Interests – Operating Partnership Units that are classified in permanent equity at June 30, 2017 and December 31, 2016.

Net proceeds from EQR Common Share and Preferred Share (see definition below) offerings are contributed by EQR to ERPOP.  In return for those contributions, EQR receives a number of OP Units in ERPOP equal to the number of Common Shares it has issued in the equity offering (or in the case of a preferred equity offering, a number of preference units in ERPOP equal in number and having the same terms as the Preferred Shares issued in the equity offering).  As a result, the net offering proceeds from Common Shares and Preferred Shares are allocated between shareholders’ equity and Noncontrolling Interests – Operating Partnership to account for the change in their respective percentage ownership of the underlying equity of ERPOP.

The Limited Partners of the Operating Partnership as of June 30, 2017 include various individuals and entities that contributed their properties to the Operating Partnership in exchange for OP Units, as well as the equity positions of the holders of restricted units.  Subject to certain exceptions (including the “book-up” requirements of restricted units), Limited Partners may exchange their Units with EQR for Common Shares on a one-for-one basis.  The carrying value of the Limited Partner Units (including redeemable interests) is allocated based on the number of Limited Partner Units in total in proportion to the number of Limited Partner Units in total plus the number of General Partner Units.  Net income is allocated to the Limited Partner Units based on the weighted average ownership percentage during the period.

The Operating Partnership has the right but not the obligation to make a cash payment instead of issuing Common Shares to any and all holders of Limited Partner Units requesting an exchange of their OP Units with EQR.  Once the Operating Partnership elects not to redeem the Limited Partner Units for cash, EQR is obligated to deliver Common Shares to the exchanging limited partner.

The Limited Partner Units are classified as either mezzanine equity or permanent equity.  If EQR is required, either by contract or securities law, to deliver registered Common Shares, such Limited Partner Units are differentiated and referred to as “Redeemable Limited Partner Units”.  Instruments that require settlement in registered shares cannot be classified in permanent equity as it is not always completely within an issuer's control to deliver registered shares.  Therefore, settlement in cash is assumed and that responsibility for settlement in cash is deemed to fall to the Operating Partnership as the primary source of cash for EQR, resulting in presentation in the mezzanine section of the balance sheet.  The Redeemable Limited Partner Units are adjusted to the greater of carrying value or fair market value based on the Common Share price of EQR at the end of each respective reporting period.  EQR has the ability to deliver unregistered Common Shares for the remaining portion of the Limited Partner Units that are classified in permanent equity at June 30, 2017 and December 31, 2016.

The carrying value of the Redeemable Limited Partner Units is allocated based on the number of Redeemable Limited PartnerUnitsinproportiontothenumberofLimitedPartnerUnitsintotal.  SuchpercentageofthetotalcarryingvalueofLimited Partner Units which is ascribed to the Redeemable Limited Partner Units is then adjusted to the greater of carrying value or fair market value as described above.  As of June 30, 2017, the Redeemable Limited Partner Units have a redemption value of approximately$380.5million,whichrepresentsthevalueofCommonSharesthatwouldbeissuedinexchangefortheRedeemable Limited PartnerUnits.

In September 2009, the Company announced the establishment of an At-The-Market (“ATM”) share offering program which would allow EQR to sell Common Shares from time to time into the existing trading market at current market prices as wellasthroughnegotiatedtransactions.  PerthetermsofERPOP'spartnershipagreement,EQRcontributesthenetproceedsfrom all equity offerings to the capital of ERPOP in exchange for additional OP Units (on a one-for-one Common Share per OP Unit basis).  The program currently has a maturity of June 2019.  EQR has the authority to issue 13.0 million shares but has not issued any shares under this program since September 2012.

The Company may repurchase up to 13.0 million Common Shares under its share repurchase program.  No shares were repurchased during the six months ended June 30, 2017 and as a result, EQR has remaining authorization to repurchase up to 13.0 million of its shares under the repurchase program as of June 30, 2017.

Note: The above tables exclude EQR's ownership interest in ERPOP, private equity fund investments, and the Company's interests in unconsolidated joint ventures established in connection with the acquisition of certain real estate related assets from Archstone Enterprise LP ("Archstone").  These ventures owned certain Archstone assets and succeeded to certain residual Archstone liabilities/litigation, as well as responsibility for tax protection arrangements and third-party preferred interests in former Archstone subsidiaries.  The preferred interests had an aggregate liquidation value of $39.5 million at June 30, 2017.  The ventures are owned 60% by the Company.  See below for further discussion.  

Operating Properties

The Company has various equity interests in certain limited partnerships owning 16 properties containing 2,783 apartment units.  Each partnership owns a multifamily property.  The Company is the general partner of these limited partnerships and is responsible for managing the operations and affairs of the partnerships as well as making all decisions regarding the businesses of the partnerships.  The limited partners are not able to exercise substantive kick-out or participating rights.  As a result, the partnerships qualify as VIEs.  The Company has a controlling financial interest in the VIEs and, thus, is the VIEs' primary beneficiary.  The Company has both the power to direct the activities of the VIEs that most significantly impact the VIEs' economic performance as well as the obligation to absorb losses or the right to receive benefits from the VIEs that could potentially be significant to the VIEs.  As a result, the partnerships are required to be consolidated on the Company's balance sheet.

The Company has a 75% equity interest in the Wisconsin Place joint venture.  The project contains a mixed-use site located in Chevy Chase, Maryland consisting of residential, retail, office and accessory uses, including underground parking facilities.  The joint venture owns the 432 unit residential component, but has no ownership interest in the retail and office components.  At June 30, 2017, the residential component had a net book value of $168.2 million.  The Company is the managing member and is responsible for conducting all administrative day-to-day matters and affairs of the joint venture as well as implementing all decisions with respect to the joint venture.  The limited partner is not able to exercise substantive kick-out or participating rights.  As a result, the joint venture qualifies as a VIE.  The Company has a controlling financial interest in the VIE and, thus, is the VIE's primary beneficiary.  The Company has both the power to direct the activities of the VIE that most significantly impact the VIE's economic performance as well as the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.  As a result, the entity that owns the residential component is required to be consolidated on the Company's balance sheet.

The Wisconsin Place joint venture also retains an unconsolidated interest in an entity that owns the land underlying the entire project and owns and operates the parking facility.  At June 30, 2017, the basis of this investment was $45.7 million.  The joint venture, as a limited partner, does not have substantive kick-out or participating rights in the entity.  As a result, the entity qualifies as a VIE.  The joint venture does not have a controlling financial interest in the VIE and is not the VIE's primary beneficiary.  The joint venture does not have the power to direct the activities of the VIE that most significantly impact the VIE's economic performance or the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.  As a result, the entity that owns the land and owns and operates the parking facility is unconsolidated and recorded using the equity method of accounting.

The Company has a 20% equity interest in each of the Nexus Sawgrass and Domain joint ventures.  The Nexus Sawgrass joint venture owns a 501 unit apartment property located in Sunrise, Florida and the Company's interest had a basis of $4.6 million at June 30, 2017.  The Domain joint venture owns a 444 unit apartment property located in San Jose, California and the Company's interest had a basis of $8.7 million at June 30, 2017.  Both properties were funded with long-term, non-recourse secured loans from the partner.  The mortgage loan on Nexus Sawgrass has a current unconsolidated outstanding balance of $48.6 million, bears interest at 5.60% and matures January 1, 2021.  The mortgage loan on Domain has a current unconsolidated outstanding balance of $96.8 million, bears interest at 5.75% and matures January 1, 2022.  While the Company is the managing member of both of the joint ventures, the joint venture partner has significant participating rights and has active involvement in and oversight of the operations.  As a result, the entities do not qualify as VIEs.  The Company alone does not have the power to direct the activities of the entities that most significantly impact the entities' economic performance and as a result, the entities are unconsolidated and recorded using the equity method of accounting.

Other

As the sole general partner of ERPOP, EQR has exclusive control of ERPOP's day-to-day management.  The limited partners are not able to exercise substantive kick-out or participating rights.  As a result, ERPOP qualifies as a VIE.  EQR has a controlling financial interest in ERPOP and, thus, is ERPOP's primary beneficiary.  EQR has the power to direct the activities of ERPOP that most significantly impact ERPOP's economic performance as well as the obligation to absorb losses or the right to receive benefits from ERPOP that could potentially be significant to ERPOP.  As a result, ERPOP is required to be consolidated on EQR's balance sheet.

In the first quarter of 2017, the Company agreed to a maximum investment of $5.0 million in a private equity fund which primarily focuses on real estate technology investments.  The Company will account for the investment under the equity method of accounting.  As of June 30, 2017, the Company’s interest had a basis of approximately $0.9 million.

On February 27, 2013, in connection with the acquisition of Archstone, subsidiaries of the Company entered into three limited liability company agreements (collectively, the “Residual JV”).  The Residual JV owned certain Archstone assets and succeeded to certain residual Archstone liabilities/litigation.  The Residual JV is owned 60% by the Company and 40% by its joint venture partner.  TheCompany's basis at June 30, 2017 was a net obligation of $0.7 million.  The Residual JV is managed by a Management Committee consisting of two members from each of the Company and its joint venture partner.  Both partners have equal participation in the Management Committee and all significant participating rights are shared by both partners.  As a result, the Residual JV does not qualify as a VIE.  The Company alone does not have the power to direct the activities of the Residual JV that most significantly impact the Residual JV's economic performance and as a result, the Residual JV is unconsolidated and recorded using the equity method of accounting.  The Residual JV has sold all of the real estate assets that were acquired as part of the acquisition of Archstone, including all of the German assets, and is in the process of winding down all remaining activities.

On February 27, 2013, in connection with the acquisition of Archstone, a subsidiary of the Company entered into a limited liability company agreement (the “Legacy JV”), through which they assumed obligations of Archstone in the form of preferred interests, some of which are governed by tax protection arrangements.  At June 30, 2017, the remaining preferred interests had an aggregate liquidation value of $39.5 million, our share of which is included in other liabilities in the accompanying consolidated balance sheets.  Obligations of the Legacy JV are borne 60% by the Company and 40% by its joint venture partner.  The Legacy JV is managed by a Management Committee consisting of two members from each of the Company and its joint venture partner.  Both partners have equal participation in the Management Committee and all significant participating rights are shared by both partners.  As a result, the Legacy JV does not qualify as a VIE.  The Company alone does not have the power to direct the activities of the Legacy JV that most significantly impact the Legacy JV's economic performance and as a result, the Legacy JV is unconsolidated and recorded using the equity method of accounting.

Fair Value Disclosures [Abstract]

Derivative and Other Fair Value Instruments

9. Derivative and Other Fair ValueInstruments

The valuation of financial instruments requires the Company to make estimates and judgments that affect the fair value of the instruments.  The Company, where possible, bases the fair values of its financial instruments, including its derivative instruments, on listed market prices and third party quotes.  Where these are not available, the Company bases its estimates on current instruments with similar terms and maturities or on other factors relevant to the financial instruments.

In the normal course of business, the Company is exposed to the effect of interest rate changes.  The Company seeks to manage these risks by following established risk management policies and procedures including the use of derivatives to hedge interest rate risk on debt instruments.  The Company may also use derivatives to manage commodity prices in the daily operations of the business.

Athree-levelvaluationhierarchyexistsfordisclosureoffairvaluemeasurements.  Thevaluationhierarchyisbasedupon thetransparencyofinputstothevaluationofanassetorliabilityasofthemeasurementdate.  Afinancialinstrument’scategorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.  The three levels are defined asfollows:

• Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

• Level 2 – Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

• Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair valuemeasurement.

The Company’s derivative positions are valued using models developed by the respective counterparty as well as models developed internally by the Company that use as their basis readily observable market parameters (such as forward yield curves and credit default swap data).  Employee holdings other than Common Shares within the supplemental executive retirement plan (the “SERP”) are valued using quoted market prices for identical assets and are included in other assets and other liabilities on the consolidated balance sheets.  Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners are valued using the quoted market price of Common Shares.  The fair values disclosed for mortgage notes payable and unsecured debt (including its commercial paper) were calculated using indicative rates provided by lenders of similar loans in the case of mortgage notes payable and the private unsecured debt (including its commercial paper) and quoted market prices for each underlying issuance in the case of the public unsecured notes.

ThecarryingvaluesoftheCompany’smortgagenotespayableandunsecureddebt (including its commercial paper and line of credit)wereapproximately$3.7billionand $5.2billion,respectively,atJune 30, 2017.  ThefairvaluesoftheCompany’smortgagenotespayableandunsecureddebt (including its commercial paper and line of credit)were approximately $3.8 billion (Level 2) and $5.4 billion (Level 2), respectively, at June 30, 2017.  The carrying values of the Company'smortgagenotespayableandunsecureddebt(includingitscommercialpaper)wereapproximately$4.1billionand $4.9 billion, respectively, at December 31, 2016.  The fair values of the Company’s mortgage notes payable and unsecured debt (includingitscommercialpaper)wereapproximately$4.2billion(Level2)and$5.0billion(Level2),respectively,atDecember 31, 2016.  The fair values of the Company’s financial instruments (other than mortgage notes payable, unsecured notes, commercial paper, line of creditandderivativeinstruments),includingcashandcashequivalentsandotherfinancialinstruments,approximatetheircarrying or contractvalues.

Individually Significant Dispositions

11. IndividuallySignificantDispositions

The Company executed an agreement with controlled affiliates of Starwood Capital Group ("Starwood") on October 23, 2015 to sell a portfolio of 72 operating properties consisting of 23,262 apartment units located in five markets across the United States for $5.365 billion (the "Starwood Transaction" or “Starwood Portfolio”).  The Starwood Portfolio represented substantially all of the assets in the Company’s South Florida and Denver markets and certain suburban assets in the Washington D.C., Seattle and Los Angeles markets.  On January 26 and 27, 2016, the Company closed on the sale of the entire portfolio described above.

The Company concluded that the Starwood Transaction did not qualify for discontinued operations reporting as it did not represent a strategic shift that had a major effect on the Company’s operations and financial results.  The Company has been investing only in its six coastal markets (Boston, New York, Washington D.C., Southern California, San Francisco and Seattle) and has not been acquiring or developing any new assets in its other markets.  Over the past several years, the Company has been repositioning its portfolio by selling its suburban assets located in markets outside its six core coastal markets.  The sale of the Starwood Portfolio represented the continuation of the above strategy.  However, the Company concluded that the Starwood Transaction did qualify as an individually significant component of the Company as the amount received upon disposal exceeded 10% of total assets, and NOI (see definition in Note 13) of the Starwood Portfolio represented approximately 2.3% of consolidated NOI (for the approximate one-month period owned in 2016) for the six months ended June 30, 2016 and approximately 15.7% of consolidated NOI for the year ended December 31, 2015.  As a result, the following table summarizes the results of operations attributable to the Starwood Transaction for the six months and quarter ended June 30, 2016 (amounts in thousands):

The Company, as an owner of real estate, is subject to various Federal, state and local environmental laws.  Compliance by the Company with existing laws has not had a material adverse effect on the Company.  However, the Company cannot predict the impact of new or changed laws or regulations on its current properties or on properties that it may acquire in the future.  As of June 30, 2017, the Company does have an environmental reserve of approximately $3.9 million related to vacant land that it owns adjacent to one of its operating properties.

TheCompanyhasestablishedareserverelatedtovariouslitigationmattersassociatedwithitsMassachusettsproperties and periodically assesses the adequacy of the reserve and makes adjustments as necessary.  As of June 30, 2017,the reserve totaled approximately $0.9million.  While no assurances can be given, the Company does not believe that the ultimate resolution of any of these remaining litigation matters, if adversely determined, would have a material adverse effect on the Company.

The Company does not believe there is any other litigation pending or threatened against it that, individually or in the aggregate, may reasonably be expected to have a material adverse effect on the Company.

As of June 30, 2017, the Company has five wholly owned projects totaling 1,720 apartment units in various stages of development with commitments to fund of approximately $123.2 million and estimated completion dates ranging through December 31, 2018, as well as other completed development projects that are in various stages of lease up or are stabilized.

Segment Reporting [Abstract]

Reportable Segments

13. ReportableSegments

Operating segments are defined as components of an enterprise that engage in business activities from which they may earn revenues and incur expenses and about which discrete financial information is available that is evaluated regularly by the chiefoperatingdecisionmaker.  Thechiefoperatingdecisionmakerdecideshowresourcesareallocatedandassessesperformance on a recurring basis at leastquarterly.

The Company’s primary business is the acquisition, development and management of multifamily residential properties, which includes the generation of rental and other related income through the leasing of apartment units to residents.  The chief operating decision maker evaluates the Company's operating performance geographically by market and both on a same store and non-same store basis.  The Company’s same store operating segments located in its coastal markets represent its reportable segments.  The Company's operating segments located in its other markets (Phoenix) that are not material have also been included in the tables presented below.  

The Company’s fee and asset management and development activities are other business activities that do not constitute an operating segment and as such, have been aggregated in the "Other" category in the tables presented below.

The primary financial measure for the Company’s rental real estate segment is net operating income (“NOI”), which representsrentalincomeless:1) propertyandmaintenanceexpenseand2) realestatetaxesandinsuranceexpense(allasreflected in the accompanying consolidated statements of operations and comprehensive income).  TheCompanybelievesthat NOI is helpful to investors as a supplemental measure of its operating performance because it is a direct measure of the actual operating results of the Company’s apartment properties.  Revenues for all leases are reflected on a straight-line basis in accordance with GAAP for the current and comparable periods.

Summary Of Significant Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.  In the opinion of management, all adjustments (consisting of normal recurring accruals) and certain reclassifications considered necessary for a fair presentation have been included.  Certain reclassifications have been made to the prior period financial statements in order to conform to the current year presentation.  These reclassifications did not have an impact on net income previously reported.  Operating results for the six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

In preparation of the Company’s financial statements in conformity with accounting principles generally accepted in the United States, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from these estimates.

The balance sheets at December 31, 2016 have been derived from the audited financial statements at that date but do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.

For further information, including definitions of capitalized terms not defined herein, refer to the consolidated financial statements and footnotes thereto included in the Company’s and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2016.

Income and Other Taxes

Income and Other Taxes

Due to the structure of EQR as a REIT and the nature of the operations of its operating properties, no provision for federal income taxes has been made at the EQR level.  In addition, ERPOP generally is not liable for federal income taxes as the partners recognize their proportionate share of income or loss in their tax returns; therefore no provision for federal income taxes has been made at the ERPOP level.  Historically, the Company has generally only incurred certain state and local income, excise and franchise taxes.  The Company has elected Taxable REIT Subsidiary (“TRS”) status for certain of its corporate subsidiaries and as a result, these entities will incur both federal and state income taxes on any taxable income of such entities after consideration of any net operating losses.

Deferred tax assets and liabilities applicable to the TRS are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.  These assets and liabilities are measured using enacted tax rates for which the temporary differences are expected to be recovered or settled.  The effects of changes in tax rates on deferred tax assets and liabilities are recognized in earnings in the period enacted.  The Company’s deferred tax assets are generally the result of tax affected suspended interest deductions, net operating losses, differing depreciable lives on capitalized assets and the timing of expense recognition for certain accrued liabilities.  As of June 30, 2017, the Company has recorded a deferred tax asset, which is fully offset by a valuation allowance due to the uncertainty of realization.  The Company currently anticipates electing REIT status for its primary TRS upon filing the 2016 tax return in the third quarter of 2017.  This election will be retroactive to January 1, 2016.

InJanuary2016,theFASBissuedanewstandardwhichrequirescompaniestomeasureallequitysecuritieswithreadily determinablefairvaluesatfairvalueonthebalancesheet,withchangesinfairvaluerecognizedinnetincome.  Thenewstandard will be effective for the Company beginning on January 1, 2018.  The Company does not expect that this will have a material effect on its consolidated results of operations or financialposition.

InFebruary2016,the FASB issued a new leases standard which sets out principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessors and lessees).  The new standard requires the following:

• Lessors – Leases will be accounted for using an approach that is substantially equivalent to existing guidance for operating, sales-type and financing leases, but aligned with the new revenue recognition standard.  Lessors will be required to allocate lease payments to separate lease and non-lease components of each lease agreement, with the non-lease components evaluated under the new revenue recognition standard.

• Lessees – Leases will be accounted for using a dual approach, classifying leases as either operating or finance based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee.  This classification will determine whether the lease expense is recognized on a straight-line basis over the term of the lease (for operating leases) or based on an effective interest method with a front-loaded expense recognition (for finance leases).  A lessee is also required to record a right-of-use asset and a lease liability on its balance sheet for all leases with a term of greater than 12 months regardless of their classification as operating or finance leases.  Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases.

The new standard will be effective for the Company beginning on January 1, 2019, with early adoption permitted, though the Company currently anticipates adopting the new standard on the effective date.  The new standard must be adopted using a modified retrospective method, which requires application of the new guidance at the beginning of the earliest comparative period presented and provides for certain practical expedients, which the Company currently anticipates electing.  The Company anticipates that its residential and retail/commercial leases where it is the lessor will continue to be accounted for as operating leases under the new standard.  Therefore, the Company does not currently anticipate significant changes in the accounting for its lease revenues.  The Company is also the lessee under various corporate office and ground leases, which it will be required to recognize right of use assets and related lease liabilities on its consolidated balance sheets upon adoption.  The Company currently anticipates that its corporate office leases where it is the lessee will continue to be accounted for as operating leases under the new standard.  Based on its anticipated election of the practical expedients, the Company would not be required to reassess the classification of existing ground leases and therefore these leases would continue to be accounted for as operating leases.  However, in the event we modify existing ground leases and/or enter into new ground leases after adoption of the new standard, such leases will likely be classified as finance leases.  The Company will continue to evaluate the impact of adopting the new leases standard on its consolidated results of operations and financial position.

In June 2016, the FASB issued a new standard which requires companies to adopt a new approach for estimating credit losses on certain types of financial instruments, such as trade and other receivables and loans.  The standard will require entities to estimate a lifetime expected credit loss for most financial instruments, including trade receivables.  The new standard will be effective for the Company beginning on January 1, 2020, with early adoption permitted beginning January 1, 2019.  TheCompanyiscurrentlyevaluatingtheimpactofadoptingthenewstandardonitsconsolidatedresultsofoperationsand financial position.

InAugust2016andOctober2016,theFASBissuednewstandardstoclarifyhowspecifictransactionsareclassifiedand presented on the statement of cash flows.  Among other clarifications, the new standards specifically provide guidance for the following items within the statement of cash flows which have required significant judgment in thepast:

• Cash payments related to debt prepayments or extinguishment costs are to be classified within financingactivities;

• The portion of the cash payment made to settle a zero-coupon bond or a bond with an insignificant cash coupon attributable to accreted interest related to a debt discount is to be classified as a cash outflow within operating activities, and the portion attributable to the principal is to be classified within financingactivities;

• Insurance settlement proceeds are to be classified based on the nature of theloss;

• Companies must elect to classify distributions received from equity method investees using either a cumulative earnings approach or a look-through approach and the election must be disclosed;and

• Restrictedcashwillbeincludedwithcashandcashequivalentsonthestatementofcashflows.  Totalcashandcash equivalents and restricted cash are to be reconciled to the related line items on the balancesheet.

InFebruary 2017,theFASB issuedanewstandardwhich clarifies the accounting treatment for partial sales of nonfinancial assets (i.e. real estate).  The standard clarifies that partial sales transactions include contributions of nonfinancial assets to a joint venture or other noncontrolled investee.  Companies must recognize a full gain or loss on transfers of nonfinancial assets to equity method investees.  The standard requires companies to derecognize distinct nonfinancial assets or distinct in substance nonfinancial assets in partial sale transactions when it does not have a controlling financial interest in the legal entity that holds the asset and transfers control of the asset.  Once the distinct nonfinancial asset is transferred, the company is required to measure any non-controlling interest it receives or retains at fair value and recognize a full gain or loss on the transaction.  If a company transfers ownership interests in a consolidated subsidiary and continues to maintain a controlling financial interest, the company does not derecognize the assets or liabilities, and accounts for the transaction as an equity transaction and no gain or loss is recognized. The new standard will be effective for the Company beginning on January 1, 2018 and early adoption was permitted beginning on January 1, 2017.  The Company anticipates adopting the new standard concurrently with the new revenue recognition standard.  The new standard may be applied retrospectively to each prior period presented or prospectively with the cumulative effect recognized as of the date of adoption.  The Company is currently evaluating the impact of adopting the new standard on its consolidated results of operations and financial position.

Other

The Company is the controlling partner in various consolidated partnerships owning 17 properties and 3,215 apartment units having a noncontrolling interest book value of $6.3 million at June 30, 2017.  The Company is required to make certain disclosures regarding noncontrolling interests in consolidated limited-life subsidiaries.  Of the consolidated entities described above, the Company is the controlling partner in limited-life partnerships owning four properties having a noncontrolling interest deficit balance of $7.4 million.  These four partnership agreements contain provisions that require the partnerships to be liquidated through the sale of their assets upon reaching a date specified in each respective partnership agreement.  The Company, as controlling partner, has an obligation to cause the property owning partnerships to distribute the proceeds of liquidation to the Noncontrolling Interests in these Partially Owned Properties only to the extent that the net proceeds received by the partnerships from the sale of their assets warrant a distribution based on the partnership agreements.  As of June 30, 2017, the Company estimates the value of Noncontrolling Interest distributions for these four properties would have been approximately $64.4 million (“Settlement Value”) had the partnerships been liquidated.  This Settlement Value is based on estimated third party consideration realized by the partnerships upon disposition of the four Partially Owned Properties and is net of all other assets and liabilities, including yield maintenance on the mortgages encumbering the properties, that would have been due on June 30, 2017 had those mortgages been prepaid.  Due to, among other things, the inherent uncertainty in the sale of real estate assets, the amount of any potential distribution to the Noncontrolling Interests in the Company's Partially Owned Properties is subject to change.  To the extent that the partnerships' underlying assets are worth less than the underlying liabilities, the Company has no obligation to remit any consideration to the Noncontrolling Interests in these Partially Owned Properties.
