EXPLANATORY NOTE

This report combines the reports on Form 10-Q for the quarterly period ended June 30, 2011 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, 2011 owned an approximate 95.6% ownership interest in ERPOP. The remaining 4.4% interest is owned by limited partners. As the sole general partner of ERPOP, EQR has exclusive control of ERPOP’s day-to-day management.

The Company is structured as an umbrella partnership REIT (“UPREIT”) and contributes all net proceeds from its various equity offerings to the Operating Partnership. In return for those contributions, the Company receives a number of OP Units (see definition below) in the Operating Partnership equal to the number of Common Shares it has issued in the equity offering. Contributions of properties to the Company can be structured as tax-deferred transactions through the issuance of OP Units in the Operating Partnership. Based on the terms of ERPOP’s partnership agreement, OP Units can be exchanged with Common Shares on a one-for-one basis. The Company maintains a one-for-one relationship between the OP Units of the Operating Partnership issued to EQR and the Common Shares issued to the public.

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.

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 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 public equity from time to time 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 the Company, which are contributed to the capital of the Operating Partnership in exchange for additional limited partnership interests in the Operating Partnership (“OP Units”) (on a one-for-one Common Share per OP Units 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, the issuance of secured and unsecured debt and equity securities, including additional OP Units, and proceeds received from disposition of certain properties and joint ventures.

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 and development joint venture partners. 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 significant 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 the Operating Partnership, the Company consolidates the Operating Partnership 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 promulgated under the Securities Act of 1933, as amended. 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. Operating results for the ~~quarter~~six months ended ~~March 31,~~June 30, 2011 are not necessarily indicative of the results that may be expected for the year ending December 31, 2011.

In preparation of the ~~Operating Partnership’s~~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 ~~sheet~~sheets at December 31, 2010 ~~has~~have been derived from the audited financial statements at that date but does 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 each of the Company’s and the Operating Partnership’s annual ~~report~~reports on Form 10-K for the year ended December 31, 2010.

Income and Other Taxes

~~The Operating Partnership~~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 ~~the Operating Partnership’s~~ income or loss in their tax returns; therefore no provision for federal income taxes has been made at the ERPOP level. Historically, the ~~Operating Partnership~~Company has generally only incurred certain state and local income, excise and franchise taxes. The ~~Operating Partnership~~Company has elected Taxable REIT Subsidiary (“TRS”) status for certain of its corporate subsidiaries ~~primarily those entities engaged in condominium conversion and corporate housing activities~~ 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 entities 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 ~~Operating Partnership’s~~Company’s deferred tax assets are generally the result of tax affected amortization of goodwill, differing depreciable lives on capitalized assets and the timing of expense recognition for certain accrued liabilities. As of ~~March 31,~~June 30, 2011, the ~~Operating Partnership~~Company has recorded a deferred tax asset of approximately $38.7 million, which is fully offset by a valuation allowance due to the uncertainty in forecasting future TRS taxable income.

Other

Effective January 1, 2010, in an effort to improve financial standards for transfers of financial assets, more stringent conditions for reporting a transfer of a portion of a financial asset as a sale (e.g. loan participations) are required, the concept of a “qualifying special-purpose entity” and special guidance for guaranteed mortgage securitizations are eliminated, other sale-accounting criteria is clarified and the initial measurement of a transferor’s interest in transferred financial assets is changed. This does not have a material effect on the ~~Operating Partnership’s~~Company’s consolidated results of operations or financial position.

Effective January 1, 2010, the analysis for identifying the primary beneficiary of a Variable Interest Entity (“VIE”) has been simplified by replacing the previous quantitative-based analysis with a framework that is based more on qualitative judgments. The analysis requires the primary beneficiary of a VIE to be identified as the party that both (a) has the power to direct the activities of a VIE that most significantly impact its economic performance and (b) has an obligation to absorb losses or a right to receive benefits that could potentially be significant to the VIE. For the ~~Operating Partnership,~~Company, this includes its consolidated development partnerships as the ~~Operating Partnership~~Company provides substantially all of the capital for these ventures (other than third party mortgage debt, if any). For the ~~Operating Partnership,~~Company, these requirements affected only disclosures and had no impact on the ~~Operating Partnership’s~~Company’s consolidated results of operations or financial position. See Note 6 for further discussion.

The ~~Operating Partnership~~Company is required to make certain disclosures regarding noncontrolling interests in consolidated limited-life subsidiaries. ~~The Operating Partnership~~For these consolidated entities, the Company is the controlling partner in various ~~consolidated~~ partnerships owning 2322 properties and ~~4,828~~4,371 apartment units and various completed and uncompleted development properties having a noncontrolling interest book value of ~~$7.7~~$3.3 million at ~~March 31,~~June 30, 2011. Some of these 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 ~~Operating Partnership,~~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 ~~March 31,~~June 30, 2011, the ~~Operating Partnership~~Company estimates the value of Noncontrolling Interest distributions would have been approximately ~~$64.1~~$63.4 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 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 ~~March 31,~~June 30, 2011 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 ~~Operating Partnership’s~~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 ~~Operating Partnership~~Company has no obligation to remit any consideration to the Noncontrolling Interests in these Partially Owned Properties.

Effective January 1, 2010, companies are required to separately disclose the amounts of significant transfers of assets and liabilities into and out of Level 1, Level 2 and Level 3 of the fair value hierarchy and the reasons for those transfers. Companies must also develop and disclose their policy for determining when transfers between levels are recognized. In addition, companies are required to provide fair value disclosures for each class rather than each major category of assets and liabilities. For fair value measurements using significant other observable inputs (Level 2) or significant unobservable inputs (Level 3), companies are required to disclose the valuation technique and the inputs used in determining fair value for each class of assets and liabilities. This does not have a material effect on the Operating Partnership’s consolidated results of operations or financial position. See Note 11 for further discussion.

Effective January 1, 2011, companies are required to separately disclose purchases, sales, issuances and settlements on a gross basis in the reconciliation of recurring Level 3 fair value measurements. This does not have a

material effect on the ~~Operating Partnership’s~~Company’s consolidated results of operations or financial position. See Note 11 for further discussion.

Effective January 1, 2012, companies will be required to separately disclose the amounts and reasons for any transfers of assets and liabilities into and out of Level 1 and Level 2 of the fair value hierarchy. For fair value measurements using significant unobservable inputs (Level 3), companies will be required to disclose quantitative information about the significant unobservable inputs used for all Level 3 measurements and a description of the Company’s valuation processes in determining fair value. In addition, companies will be required to provide a qualitative discussion about the sensitivity of recurring Level 3 measurements to changes in the unobservable inputs disclosed, including the interrelationship between inputs. Companies will also be required to disclose information about when the current use of a non-financial asset measured at fair value differs from its highest and best use and the hierarchy classification for items whose fair value is not recorded on the balance sheet but is disclosed in the notes. The Company does not expect this will have a material effect on its consolidated results of operations or financial position.

Effective January 1, 2009, issuers of certain convertible debt instruments that may be settled in cash on conversion were required to separately account for the liability and equity components of the instrument in a manner that reflects each issuer’s nonconvertible debt borrowing rate. As the ~~Operating Partnership~~Company is required to apply this retrospectively, the accounting for ~~the Operating Partnership’s~~its $650.0 million ($482.5 million outstanding at ~~March 31,~~June 30, 2011) 3.85% convertible unsecured notes that were issued in August 2006 and mature in August 2026 was affected. The ~~Operating Partnership~~Company recognized ~~$4.6~~$9.3 million and ~~$4.6~~$9.3 million in interest expense related to the stated coupon rate of 3.85% for the ~~quarters~~six months ended ~~March 31,~~June 30, 2011 and 2010, respectively. The amount of the conversion option as of the date of issuance calculated by the ~~Operating Partnership~~Company using a 5.80% effective interest rate was $44.3 million and is being amortized to interest expense over the expected life of the convertible notes (through the first put date on August 18, 2011). Total amortization of the cash discount and conversion option discount on the unsecured notes resulted in a reduction to earnings of approximately ~~$2.0~~$3.9 million and ~~$1.9~~$3.9 million, respectively, or $0.01 per share/Unit and $0.01 per share/Unit, respectively, for the ~~quarters~~six months ended ~~March 31,~~June 30, 2011 and 2010, and is anticipated to result in a reduction to earnings of approximately $5.0 million or $0.02 per share/Unit during the full year of 2011. In addition, the ~~Operating Partnership~~Company decreased the January 1, 2009 balance of retained earnings (included in general partner’s ~~capital)~~capital in the Operating Partnership’s financial statements) by $27.0 million, decreased the January 1, 2009 balance of notes by $17.3 million and increased the January 1, 2009 balance of paid in capital (included in general partner’s ~~capital)~~capital in the Operating Partnership’s financial statements) by $44.3 million. The carrying amount of the conversion option remaining in paid in capital (included in general partner’s ~~capital)~~capital in the Operating Partnership’s financial statements) was $44.3 million at both ~~March 31,~~June 30, 2011 and December 31, 2010. The unamortized cash and conversion option discounts totaled ~~$3.0~~$1.1 million and $5.0 million at ~~March 31,~~June 30, 2011 and December 31, 2010, respectively.

On June 16, 2011, the shareholders of EQR approved the Company’s 2011 Share Incentive Plan (the “2011 Plan”). The 2011 Plan reserved 12,980,741 Common Shares for issuance. In conjunction with the approval of the 2011 Plan, no further awards may be granted under the 2002 Share Incentive Plan. The 2011 Plan expires on June 16, 2021.

EQR has a share repurchase program authorized by the Board of Trustees under which it has authorization to repurchase up to $464.6 million of its shares as of June 30, 2011. No shares were repurchased during the six months ended June 30, 2011.

During the six months ended June 30, 2011, the Company acquired all of its partner’s interest in two consolidated partially owned properties consisting of 861 apartment units for $8.6 million. In conjunction with these transactions, the Company reduced paid in capital by $5.6 million and Noncontrolling Interests — Partially Owned Properties by $3.0 million.

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 LTIP Units, are collectively referred to as the “Noncontrolling Interests — Operating Partnership”. Subject to certain exceptions (including the “book-up” requirements of LTIP 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.

The Noncontrolling Interests — Operating Partnership 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 Noncontrolling Interests — Operating Partnership are differentiated and referred to as “Redeemable Noncontrolling Interests — Operating Partnership”. Instruments that require settlement in registered shares can not 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, 2011 and December 31, 2010.

The carrying value of the Redeemable Noncontrolling Interests — Operating Partnership is allocated based on the number of Redeemable Noncontrolling Interests — Operating Partnership Units in proportion to the number of Noncontrolling Interests — Operating Partnership Units in total. Such percentage of the total carrying value of Units which is ascribed to the Redeemable Noncontrolling Interests — Operating Partnership is then adjusted to the greater of carrying value or fair market value as described above. As of June 30, 2011, the Redeemable Noncontrolling Interests — Operating Partnership have a redemption value of approximately $438.1 million, which represents the value of Common Shares that would be issued in exchange with the Redeemable Noncontrolling Interests — Operating Partnership Units.

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 Company’s declaration of trust authorizes it to issue up to 100,000,000 preferred shares of beneficial interest, $0.01 par value per share (the “Preferred Shares”), with specific rights, preferences and other attributes as the Board of Trustees may determine, which may include preferences, powers and rights that are senior to the rights of holders of the Company’s Common Shares.

Per the terms of ERPOP’s partnership agreement, EQR contributes the net proceeds from all equity offerings to the capital of ~~the Operating Partnership~~ERPOP in exchange for additional OP Units (on a one-for-one Common Share per OP Unit basis). During the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, EQR issued approximately 3.0 million Common Shares at an average price of $50.84 per share for total consideration of approximately $154.5 million through the ATM program. Concurrent with these transactions, ~~the Operating Partnership~~ERPOP issued approximately 3.0 million OP Units to EQR. EQR has not issued any shares under this program since January 13, 2011. Including its February 2011 prospectus supplement which added approximately 5.7 million Common Shares, EQR has 10.0 million Common Shares remaining available for issuance under the ATM program as of June 30, 2011.

~~EQR has~~Equity Residential” in this note for a discussion of the Company’s 2011 Plan and share repurchase program authorized by the Board of Trustees under which it has authorization to repurchase up to $464.6 million of its shares as of March 31, 2011. No shares were repurchased during the quarter ended March 31, 2011.program.

During the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, the Operating Partnership acquired all of its partner’s interest in ~~one~~two consolidated partially owned ~~property~~properties consisting of ~~404~~861 apartment units for ~~$0.5~~$8.6 million. In conjunction with ~~this transaction,~~these transactions, the Operating Partnership reduced paid in capital (included in general partner’s ~~capital)~~capital in the Operating Partnership’s financial statements) by ~~$0.5~~$5.6 million and Noncontrolling Interests — Partially Owned Properties by $3.0 million.

The Limited Partners of the Operating Partnership as of ~~March 31,~~June 30, 2011 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 LTIP Units. Subject to certain exceptions (including the “book-up” requirements of LTIP Units), Limited Partners may exchange their Units with EQR for ~~EQR~~ 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 ~~EQR~~ 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 ~~EQR~~ 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 ~~EQR~~ Common Shares, such Limited Partner Units are differentiated and referred to as “Redeemable Limited Partner Units”. Instruments that require settlement in registered shares can not 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 ~~EQR~~ Common Shares for the remaining portion of the Limited Partner Units that are classified in permanent equity at ~~March 31,~~June 30, 2011 and December 31, 2010.

The carrying value of the Redeemable Limited Partner Units is allocated based on the number of Redeemable Limited Partner Units in proportion to the number of Limited Partner Units in total. Such percentage of the total carrying value of Limited 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 ~~March 31,~~June 30, 2011, the Redeemable Limited Partner Units have a redemption value of approximately ~~$416.3~~$438.1 million, which represents the value of ~~EQR~~ Common Shares that would be issued in exchange with the Redeemable Limited Partner Units.

The following table presents the change in the redemption value of the Redeemable Limited Partners for the ~~quarter~~six months ended ~~March 31,~~June 30, 2011 (amounts in thousands):

Derivative and Other Fair Value Instruments

The valuation of financial instruments requires the ~~Operating Partnership~~Company to make estimates and judgments that affect the fair value of the instruments. The ~~Operating Partnership,~~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 ~~Operating Partnership~~ Company

bases its estimates on current instruments with similar terms and maturities or on other factors relevant to the financial instruments.

The carrying values of the ~~Operating Partnership’s~~Company’s mortgage notes payable and unsecured notes were approximately ~~$4.6~~$4.4 billion and $5.1 billion, respectively, at ~~March 31,~~June 30, 2011. The fair values of the ~~Operating Partnership’s~~Company’s mortgage notes payable and unsecured notes were approximately ~~$4.5~~$4.4 billion and $5.4 billion, respectively, at ~~March 31,~~June 30, 2011. The fair values of the ~~Operating Partnership’s~~Company’s financial instruments (other than mortgage notes payable, unsecured notes, derivative instruments and investment securities) including cash and cash equivalents and other financial instruments, approximate their carrying or contract values.

In the normal course of business, the ~~Operating Partnership~~Company is exposed to the effect of interest rate changes. The ~~Operating Partnership~~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 following table summarizes the ~~Operating Partnership’s~~Company’s consolidated derivative instruments at ~~March 31,~~June 30, 2011 (dollar amounts are in thousands):

A three-level valuation hierarchy exists for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization 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 as follows:

	•		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 value measurement.

The following tables provide a summary of the fair value measurements at ~~March 31,~~June 30, 2011 and December 31, 2010 for each major category of assets and liabilities measured at fair value on a recurring basis:

~~14. Commitments and Contingencies~~

Commitments and Contingencies

The ~~Operating Partnership,~~Company, as an owner of real estate, is subject to various Federal, state and local environmental laws. Compliance by the ~~Operating Partnership~~Company with existing laws has not had a material adverse effect on the ~~Operating Partnership.~~Company. However, the ~~Operating Partnership~~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.

The ~~Operating Partnership~~Company is party to a housing discrimination lawsuit brought by a non-profit civil rights organization in April 2006 in the U.S. District Court for the District of Maryland. The suit alleges that the ~~Operating Partnership~~Company designed and built approximately 300 of its properties in violation of the accessibility requirements of the Fair Housing Act and Americans With Disabilities Act. The suit seeks actual and punitive damages, injunctive relief (including modification of non-compliant properties), costs and attorneys’ fees. The ~~Operating Partnership~~Company believes it has a number of viable defenses, including that a majority of the named properties were completed before the operative dates of the statutes in question and/or were not designed or built by the ~~Operating Partnership.~~Company. Accordingly, the ~~Operating Partnership~~Company is defending the suit vigorously. Due to the pendency of the ~~Operating Partnership’s~~Company’s defenses and the uncertainty of many other critical factual and legal issues, it is not possible to determine or predict the outcome of the suit or a possible loss or a range of loss, and no amounts have been accrued at ~~March 31,~~June 30, 2011. While no assurances can be given, the ~~Operating Partnership~~Company does not believe that the suit, if adversely determined, would have a material adverse effect on the ~~Operating Partnership.~~Company.

The ~~Operating Partnership~~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 ~~Operating Partnership.~~Company.

The ~~Operating Partnership~~Company has established a reserve and recorded a corresponding reduction to its net gain on sales of discontinued operations related to potential liabilities associated with its condominium conversion activities. The reserve

covers potential product liability related to each conversion. The ~~Operating Partnership~~Company periodically assesses the adequacy of the reserve and makes adjustments as necessary. During the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, the ~~Operating Partnership~~Company recorded additional reserves of approximately $0.1 million, paid

approximately ~~$0.2~~$0.6 million in settlements and legal fees and released approximately ~~$0.2~~$0.3 million of remaining reserves for settled claims. As a result, the ~~Operating Partnership~~Company had total reserves of approximately ~~$2.9~~$2.5 million at ~~March 31,~~June 30, 2011. While no assurances can be given, the ~~Operating Partnership~~Company does not believe that the ultimate resolution of these potential liabilities, if adversely determined, would have a material adverse effect on the ~~Operating Partnership.~~Company.

As of ~~March 31,~~June 30, 2011, the ~~Operating Partnership~~Company has four consolidated projects totaling 747 apartment units in various stages of development with commitments to fund of approximately $133.5 million and estimated completion dates ranging through September 30, 2013, as well as other completed development projects that are in various stages of lease up or are stabilized. ~~Some of the~~The projects ~~were~~under development are being developed solely by the ~~Operating Partnership,~~Company, while ~~others~~the completed development projects were either developed solely by the Company or co-developed with various third party development partners. The development venture agreements with partners are primarily deal-specific, with differing terms regarding profit-sharing, equity contributions, returns on investment, buy-sell agreements and other customary provisions. The partner is most often the “general” or “managing” partner of the development venture. The typical buy-sell arrangements contain appraisal rights and provisions that provide the right, but not the obligation, for the ~~Operating Partnership~~Company to acquire the partner’s interest in the project at fair market value upon the expiration of a negotiated time period (typically two to five years after substantial completion of the project).

As of June 30, 2011, the Company has one unconsolidated project totaling 501 apartment units under development with commitments to fund of approximately $2.4 million and an estimated completion date in the second quarter of 2013. The Company is the managing member of the joint venture, is responsible for constructing the project and has given certain construction cost overrun guarantees. The buy-sell arrangements contain provisions that provide the right, but not the obligation, for the Company to acquire the partner’s interest or sell its interest at any time following the occurrence of certain pre-defined events (including at stabilization) described in the development venture agreement.

15. Reportable Segments

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by senior management. Senior management decides how resources are allocated and assesses performance on a monthly basis.

The ~~Operating Partnership’s~~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. Senior management evaluates the performance of each of our apartment communities individually and geographically, and both on a same store and non-same store basis; however, each of our apartment communities generally has similar economic characteristics, residents, products and services. The ~~Operating Partnership’s~~Company’s operating segments have been aggregated by geography in a manner identical to that which is provided to its chief operating decision maker.

The ~~Operating Partnership’s~~Company’s fee and asset management, development (including its partially owned properties), and condominium conversion ~~and corporate housing (Equity Corporate Housing or “ECH”)~~ activities are immaterial and do not individually meet the threshold requirements of a reportable segment and as such, have been aggregated in the “Other” segment in the tables presented below.

All revenues are from external customers and there is no customer who contributed 10% or more of the ~~Operating Partnership’s~~Company’s total revenues during the six months and quarters ended ~~March 31,~~June 30, 2011 and 2010, respectively.

The primary financial measure for the ~~Operating Partnership’s~~Company’s rental real estate segment is net operating income (“NOI”), which represents rental income less: 1) property and maintenance expense; 2) real estate taxes and insurance expense; and 3) property management expense (all as reflected in the accompanying consolidated statements of operations). The ~~Operating Partnership~~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 ~~Operating Partnership’s~~Company’s apartment communities. Current year NOI is compared to prior year NOI and current year budgeted NOI as a measure of financial performance. The following tables present NOI for each segment from our rental real estate specific to continuing operations for the six months and quarters ended ~~March 31,~~June 30, 2011 and 2010, respectively, as well as total assets at ~~March 31,~~June 30, 2011 (amounts in thousands):

	•		Repaid ~~$193.7~~$176.3 million in mortgage loans;

	•		~~Obtained $91.5 million~~Called for redemption its 3.85% convertible unsecured debt with a final maturity of ~~new mortgage loan proceeds;~~

	•		~~Acquired one operating property consisting of 322 apartment units for $100.0 million and one land parcel for $12.9 million;~~2026;

	•		Sold 15two properties containing ~~4,369~~685 apartment units for ~~$530.2~~$66.5 million; and

The interest rate on advances under the new credit facility will generally be LIBOR plus a spread (currently 1.15%) and the Company pays an annual facility fee of 0.2%. Both the spread and the facility fee are dependent on the credit rating of the Company’s long-term debt. ERPOP entered into the new revolving credit facility and EQR has guaranteed the revolving credit facility up to the maximum amount and for the full term of the facility. There is approximately $1.17 billion available on the new unsecured revolving credit facility as ~~a result, the maturity date is now October 5, 2012.~~of July 28, 2011.

For further information including definitions for capitalized terms not defined herein, refer to the consolidated financial statements and footnotes thereto included in each of the Company’s and the Operating Partnership’s Annual ~~Report~~Reports on Form 10-K for the year ended December 31, 2010.

Forward-Looking Statements

Forward-looking statements in this report 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 ~~Operating Partnership’s~~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 ~~Operating Partnership~~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 ~~Operating Partnership~~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 and/or develop 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 rates as well as higher than expected concessions. We may underestimate the costs necessary to bring an acquired property up to standards established for its intended market position or to complete a development property. Additionally, we expect that other ~~major~~ real estate investors with ~~significant~~ 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. The total number of ~~development~~ 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 ~~Operating Partnership~~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 economic and market conditions including ~~without limitation, new construction and excess inventory of multifamily housing and single family housing,~~ slow or negative employment growth ~~availability of low interest mortgages for single family home buyers~~ and household formation as well as the potential for geopolitical instability, all of which are beyond the ~~Operating Partnership’s~~Company’s control;

	•		Our residents may choose to leave our properties or not rent at all because owned housing has become a more attractive option for them due to, among other things, the availability of low interest mortgages, government programs and changes in social preferences; and

	•		Additional factors as discussed in Part I of both the Company’s and the Operating Partnership’s Annual ~~Report~~Reports on Form 10-K, particularly those under “Item 1A. Risk Factors”.

Forward-looking statements and related uncertainties are also included in the Notes to Consolidated Financial Statements in this report.

Business Objectives and Operating Strategies

The ~~Operating Partnership~~Company invests in apartment communities located in strategically targeted markets with the goal of maximizing our risk adjusted total return (operating income plus capital appreciation) on invested capital.

Our operating focus is on balancing occupancy and rental rates to maximize our revenue while exercising tight cost control to generate the highest possible return to our shareholders. Revenue is maximized by ~~driving~~attracting qualified ~~resident~~ prospects to our properties, cost-effectively converting ~~this traffic cost-effectively~~these prospects into new ~~leases~~residents at the highest rent possible, keeping our residents satisfied and renewing their leases at yet higher rents. While we believe that it is our high-quality, well-located assets that bring our customers to us, it is ~~our~~the customer service provided by our on-site personnel that keeps them renting with us and recommending us to their friends.

We use technology to engage our customers in the way that they want to be engaged. Many of our residents utilize our web-based resident portal which allows them to sign their lease, review their account and make payments, provide feedback and make service requests on-line.

We seek to maximize capital appreciation of our properties by investing in markets that are characterized by conditions favorable to multifamily property appreciation. These markets generally feature one or more of the following:

	•		High barriers to entry where, because of land scarcity or government regulation, it is difficult or costly to build new apartment properties, ~~leading to low~~creating limits on new supply;

	•		High single family home prices making our apartments a more economical housing choice;

	•		Strong economic growth leading to household formation and job growth, which in turn leads to high demand for our apartments; and

	•		An attractive quality of life leading to high demand and retention ~~and allowing~~that allows us to more ~~readily~~aggressively increase rents.

Acquisitions and developments may be financed from various sources of capital, which may include retained cash flow, issuance of additional equity and debt, ~~securities,~~ sales of properties and joint venture ~~agreements and collateralized and uncollateralized borrowings.~~agreements. In addition, the ~~Operating Partnership~~Company may acquire properties in transactions that include the issuance of limited partnership interests in the Operating Partnership (“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. ~~ERPOP~~The Company may ~~also~~ acquire land parcels to hold and/or sell based on market opportunities. The ~~Operating Partnership~~Company may also seek to acquire properties by purchasing defaulted or distressed debt that encumbers desirable properties in the hope of obtaining title to property through foreclosure or deed-in-lieu of foreclosure proceedings. The ~~Operating Partnership~~Company has also, in the past, converted some of its properties and sold them as condominiums but is not currently active in this line of business.

The ~~Operating Partnership~~Company primarily sources the funds for new property acquisitions in its core markets with the proceeds from selling assets that are older or located in non-core markets. Since ~~2006,~~2005, the ~~Operating Partnership~~Company has sold ~~almost 100,000~~over 121,000 apartment units for an aggregate sales price of approximately ~~$7.5~~$9.7 billion, ~~and~~ acquired ~~nearly 25,000~~over 38,000 apartment units in its core markets for approximately ~~$5.6 billion.~~$8.5 billion and began approximately $2.2 billion of development projects. We are currently ~~acquiring~~seeking to acquire and ~~developing~~develop assets primarily in the following targeted metropolitan areas: Boston, New York, Washington DC, South Florida, Southern California, San Francisco ~~Seattle~~ and ~~to a lesser extent Denver.~~Seattle. We also have investments (in the aggregate about ~~17.4%~~20.6% of our NOI at ~~March 31,~~June 30, 2011) in other markets including Denver, Atlanta, Phoenix, ~~Portland, Oregon,~~ New England ~~excluding Boston,~~(excluding Boston), Tampa, Orlando and Jacksonville but do not currently intend to acquire or develop new assets in these markets.

As part of its strategy, the ~~Operating Partnership~~Company purchases completed and fully occupied apartment properties, partially

completed or partially occupied properties or land on which apartment properties can be constructed. We intend to hold a diversified portfolio of assets across our target markets. As of ~~March 31,~~June 30, 2011, no single

metropolitan area accounted for more than 16.1% of our NOI, though no guarantee can be made that NOI concentration may not increase in the future.

We endeavor to attract and retain the best employees by providing them with the education, resources and opportunities to succeed. We provide many classroom and on-line training courses to assist our employees in interacting with prospects and residents as well as extensively train our customer service specialists in maintaining the equipment and appliances on our property sites. We actively promote from within and many senior corporate and property leaders have risen from entry level or junior positions. We monitor our employees’ engagement by surveying them annually and have consistently received high engagement scores.

We have a commitment to sustainability and consider the environmental impacts of our business activities. We have a dedicated in-house team that initiates and applies sustainable practices in all aspects of our business, including transactions, property operations and property management activities. With its high density, multifamily housing is, by its nature, an environmentally friendly property type. Our recent acquisition and development activities have been primarily concentrated in pedestrian-friendly urban locations near public transportation. When developing and renovating our properties, we strive to reduce energy and water usage by investing in energy saving technology while positively impacting the experience of our residents and the value of our assets. We continue to implement a combination of irrigation, lighting and HVAC improvements at our properties that will reduce energy and water consumption.

Current Environment

After much caution in 2009 due to the uncertainty in the economy and capital markets, late 2009 and early 2010 saw stabilization in the capital markets and modest improvements in the general economy. Property occupancy began to improve and in response, the Operating Partnership began acquiring assets and increasing rents for both new and renewing residents, which led to better operating and investment performance. The Operating Partnership increased rents to a greater extent in regions like the Northeast, where the economy was stronger and multifamily operating conditions were better. In 2010, the Operating Partnership ceased to hold the large cash balances (often $1.0 billion or more) that it held in 2009 in anticipation of debt maturities in an unsure capital markets climate. This had the result of increasing the Operating Partnership’s earnings by decreasing the amount of cash on hand that was earning limited interest income and instead was used to pay down higher cost debt. Finally, the Operating Partnership was aggressive in acquiring $1.5 billion of assets in its target markets in 2010.

~~Improvement continued throughout 2010, and in 2011 we~~We expect strong growth in full year same store revenue (anticipated increases ranging from ~~4.0%~~4.8% to ~~5.0%~~5.1%) and full year NOI (anticipated increases ranging from ~~5.0%~~7.0% to ~~7.5%~~8.0%) and are optimistic that the ~~improvement~~strength in fundamentals realized in 2010 and to date in 2011 will be sustained for the foreseeable future. Our strong operating results in the first ~~quarter~~half of 2011, with same store revenues up ~~4.0%~~4.5% and same store NOI up ~~7.3%~~7.4% over the ~~first quarter of~~same period in 2010, ~~now lead~~have led us to ~~believe that we may trend towards the higher end~~increase both of these same store ranges for the ~~year.~~year (from anticipated increases of 4.0% to 5.0% and 5.0% to 7.5%, respectively). Despite the anticipated improvement in operations, we ~~still~~ expect our full year Normalized Funds From Operations to fall ~~near~~toward the ~~midpoint~~lower end of our guidance ranges due to increased dilution from ~~our~~the combination of a greater than anticipated volume of dispositions and their accelerated ~~dispositions~~timing in the year (see further discussion below). as well as an increasing cap rate spread due to us reinvesting disposition proceeds in assets with lower initial yields.

The Company continues to sell non-core assets and reduce its exposure to non-core markets as we believe these assets do not fit into our long term plans and we can sell them for prices that we believe are favorable. Through July 28, 2011, we have sold 40 consolidated properties consisting of 11,952 apartment units for $1.24 billion. Based on the activity to date, the majority of our anticipated $1.5 billion in 2011 dispositions occurred in the first half of the year. The Company’s decision to accelerate the timing and increase the volume of dispositions combined with limited opportunities to reinvest the cash proceeds and/or reinvestment of the cash proceeds in assets with lower cap rates (see definition below) is dilutive to our per share results despite our strong operating performance. The Company defines dilution from transactions as the lost NOI from sales proceeds that were not reinvested in other apartment properties or were reinvested in properties with a lower cap rate. The dispositions have created a significant cash balance, which combined with the Company’s new unsecured revolving credit facility, allowed us to defer the unsecured debt offering that was previously targeted for the third quarter of 2011. The deferral of the target date for the forward starting swaps that hedge the debt offering resulted in an ineffectiveness charge of $2.6 million due to the forecasted transaction not occurring on its original target date.

Competition for the properties we are interested in acquiring is significant due to the overall improvement in market fundamentals. Based on the activity to date, we expect a slightly greater share of our $1.15 billion in anticipated 2011 acquisitions to occur in the latter half of the year. We believe our access to capital, our ability to execute large, complex transactions and our ability to efficiently stabilize large scale lease up properties provide us with a competitive advantage. The Company acquired seven consolidated properties consisting of 2,069 apartment units for $549.3 million, one commercial building for potential redevelopment for $11.8 million and one land parcel for $12.9 million during the six months ended June 30, 2011.

We currently have access to multiple sources of capital including the equity markets as well as both the secured and unsecured debt markets. In July 2010, the ~~Operating Partnership~~Company completed a $600.0 million unsecured ten year note offering with a coupon of 4.75% and an all-in effective interest rate of 5.09%. EQR also raised $291.9 million in equity under its ATM Common Share offering program in 2010 and has raised an additional $154.5 million under this program thus far in 2011.

In ~~response~~July 2011, the Company replaced its then existing unsecured revolving credit facility which was due to ~~what we believe is~~mature in February 2012 with a current robust market and favorable pricing for our non-strategic assets, we have accelerated our disposition program in 2011. Through April 28, 2011, we have sold 27 consolidated properties consisting of 7,100 apartment units for $792.0 million. Based on the activity to date, the majority of our anticipatednew $1.25 billion ~~in 2011 dispositions will occur in~~unsecured revolving credit facility maturing on July 13, 2014, subject to a one-year extension option exercisable by the ~~first half of~~Company. The Company believes that the ~~year. While the accelerated disposition program will result in increased dilution (due to the lost NOI from sales proceeds that were not reinvested in other apartment properties)~~new facility contains a diversified and strong bank group which ~~will negatively impact Normalized Funds From Operations, we believe that we can maximize long-term returns to our shareholders by selling non-strategic assets at current pricing levels.~~

Competition for the properties we are interested in acquiring is significant due to the overall improvement in market fundamentals and we expect a greater concentration of our 2011 acquisitions to occur in the latter half of the year. We believe our access to capital, our ability to execute large, complex transactions and our ability to efficiently stabilize large scale lease up properties provide us with a competitive advantage. The Operating Partnership acquired two consolidated properties consisting of 521 apartment units for $139.0 million and one commercial building for potential redevelopment for $11.8 million during the quarter ended March 31, 2011.increases its balance sheet flexibility going forward.

We believe that cash and cash equivalents, securities readily convertible to cash, current availability on our revolving credit facility and disposition proceeds for 2011 will provide sufficient liquidity to meet our funding

obligations relating to asset acquisitions, debt maturities and existing development projects through 2011. We expect that our remaining longer-term funding requirements will be met through some combination of new borrowings, equity issuances (including EQR’s ATM share offering program), property dispositions, joint ventures and cash generated from operations. There is significant uncertainty surrounding the futures of Fannie Mae and Freddie ~~Mac.~~Mac (the “Government Sponsored Enterprises” or “GSEs”). Through their lender originator networks, Fannie Mae and Freddie Mac are significant lenders both to the Company and to buyers of the Company’s properties. The two GSEs have a mandate to support affordable multifamily housing through their financing activities. Any changes to their mandates could have a significant impact on the ~~Operating Partnership~~Company and may, among other things, lead to lower values for our disposition assets and higher interest rates on our borrowings. Such changes may also provide an advantage to us by making the cost of financing single family home ownership more expensive and provide us a competitive advantage given the size of our balance sheet and the multiple sources of capital to which we have access.

We believe that the ~~Operating Partnership~~Company is well-positioned as of ~~March 31,~~June 30, 2011 because our properties are geographically diverse and were approximately 95.1% occupied ~~(95.0%~~(95.6% on a same store basis), little new multifamily rental supply will be added to most of our markets over the next several years and the long-term demographic picture is positive. We believe our strong balance sheet and ample liquidity will allow us to fund our debt maturities and development costs in the near term, and should also allow us to take advantage of investment opportunities in the future. As economic conditions continue to improve, the short-term nature of our leases and the limited supply of new rental housing being constructed should allow us to realize revenue growth and improvement in our operating results.

The ~~Operating Partnership~~Company anticipates that ~~2011~~growth in same store expenses comparing 2011 to 2010 will ~~only~~range from no change to an increase of 1.0% ~~to 2.0%~~ primarily due to modest increases in payroll expenses, real estate tax rates and utility cost growth (same store expenses increased 0.9% for 2010 when compared with the same period in the prior year). This follows three consecutive years of excellent expense control (same store expenses declined 0.1% between 2009 and 2008 and grew 2.2% between 2008 and 2007 and 2.1% between 2007 and 2006). Effective expense controls continued in the first ~~quarter~~half of 2011 as same store expenses declined ~~1.0%~~0.3% as compared to the ~~first quarter of~~same period in 2010. ~~The Operating Partnership now anticipates that its same store expenses will trend towards the lower end of its guidance range.~~

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 ~~Operating Partnership~~Company continued to invest in apartment properties located in strategically targeted markets during the ~~quarter~~six months ended ~~March 31,~~June 30, 2011 as follows:

Acquired $139.0 million of apartment properties consisting of two consolidated properties and 521 apartment units at a weighted average cap rate (see definition below) of 5.7%, both of which we deem to be in our strategic targeted markets;

~~Acquired a 97,000 square foot commercial building adjacent to our Harbor Steps apartment property in downtown Seattle for $11.8 million for potential redevelopment; and~~

Sold $261.8 million of consolidated apartment properties consisting of 12 properties and 2,731 apartment units at a weighted average cap rate of 6.7%, the majority of which was in exit or less desirable markets.

	•		Acquired $549.3 million of apartment properties consisting of seven consolidated properties and 2,069 apartment units at a weighted average cap rate (see definition below) of 5.2% and one land parcel for $12.9 million, all of which we deem to be in our strategic targeted markets;

	•		Acquired a 97,000 square foot commercial building adjacent to our Harbor Steps apartment property in downtown Seattle for $11.8 million for potential redevelopment; and

	•		Sold $1.2 billion of consolidated apartment properties consisting of 38 properties and 11,267 apartment units at a weighted average cap rate of 6.4% and one land parcel for $22.8 million, the majority of which was in exit or less desirable markets.

The ~~Operating Partnership’s~~Company’s primary financial measure for evaluating each of its apartment communities is net operating income (“NOI”). NOI represents rental income less property and maintenance expense, real estate tax and insurance expense and property management expense. The ~~Operating Partnership~~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 ~~Operating Partnership’s~~ Company’s

apartment communities. The cap rate is generally the first year NOI yield (net of replacements) on the ~~Operating Partnership’s~~Company’s investment.

Properties that the ~~Operating Partnership~~Company owned for all of both of the six months ended June 30, 2011 and 2010 (the “Six-Month 2011 Same Store Properties”), which represented 104,163 apartment units, and properties that the Company owned for all of both of the quarters ended ~~March 31,~~June 30, 2011 and 2010 (the ~~“First~~“Second Quarter 2011 Same Store Properties”), which represented ~~112,363~~105,730 apartment units, impacted the ~~Operating Partnership’s~~Company’s results of operations. ~~The First~~Both the Six-Month 2011 Same Store Properties and the Second Quarter 2011 Same Store Properties are discussed in the following paragraphs.

The ~~Operating Partnership’s~~Company’s acquisition, disposition and completed development activities also impacted overall results of operations for the six months and quarters ended ~~March 31,~~June 30, 2011 and 2010. The impacts of these activities are discussed in greater detail in the following paragraphs.

Comparison of the ~~quarter~~six months ended ~~March 31,~~June 30, 2011 to the ~~quarter~~six months ended ~~March 31,~~June 30, 2010

For the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, the ~~Operating Partnership~~Company reported diluted earnings per share/Unit of ~~$0.42~~$2.27 compared to ~~$0.18~~$0.21 per share/Unit in the same period of 2010. The difference is primarily due to higher gains from property sales in 2011 vs. 2010 and higher total property net operating income driven by the positive impact of the ~~Operating Partnership’s~~

Company’s same store and lease-up activity, partially offset by dilution from the ~~Operating Partnership’s~~Company’s 2010 and 2011 transaction activity.

For the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, income from continuing operations increased approximately ~~$17.1~~$45.6 million when compared to the ~~quarter~~six months ended ~~March 31,~~June 30, 2010. The increase in continuing operations is discussed below.

Revenues from the ~~First Quarter~~Six-Month 2011 Same Store Properties increased ~~$17.3~~$36.6 million primarily as a result of an increase in average rental rates charged to residents and an increase in ~~occupancy and a decrease in resident turnover.~~occupancy. Expenses from the ~~First Quarter~~Six-Month 2011 Same Store Properties decreased ~~$1.8~~$0.9 million primarily due to decreases in ~~repairs~~on-site payroll costs and ~~maintenance expenses~~leasing and ~~on-site payroll~~advertising costs, partially offset by increases in property management costs.

Same store NOI	$	279,708		$	260,652		$	543,716		$	506,236

For properties that the ~~Operating Partnership~~Company acquired prior to January 1, 2010 and expects to continue to own through December 31, 2011, the ~~Operating Partnership~~Company anticipates the following same store results for the full year ending December 31, 2011:


2011 Same Store Assumptions
Physical occupancy	95.2%	~~95.0~~	%
Revenue change	~~4.0%~~4.8% to ~~5.0%~~5.1%
Expense change	~~1.0%~~0.0% to ~~2.0%~~1.0%
NOI change	~~5.0%~~7.0% to ~~7.5%~~8.0%

The ~~Operating Partnership~~Company anticipates consolidated rental acquisitions of ~~$1.0~~$1.15 billion and consolidated rental dispositions of ~~$1.25~~

$1.5 billion and expects that acquisitions will have a ~~1.25%~~1.50% lower cap rate than dispositions for the full year ending December 31, 2011.

These 2011 assumptions are based on current expectations and are forward-looking.

Non-same store operating results increased approximately ~~$26.7~~$49.7 million and consist primarily of properties acquired in calendar years 2010 and 2011, as well as operations from the ~~Operating Partnership’s~~Company’s completed development ~~properties and corporate housing business.~~properties. Although the operations of both the non-same store assets and the same store assets have been positively impacted during the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, the non-same store assets have contributed a greater percentage of total NOI to the ~~Operating Partnership’s~~Company’s overall operating results primarily due to 2010 acquisitions, increasing occupancy for properties in lease-up and a longer ownership period in 2011 than 2010. This increase primarily resulted from:

	•		~~Development and other miscellaneous properties in lease-up of $9.3 million;~~

	•		~~Properties acquired in 2010 and 2011 of $13.4 million;~~

	•		~~Newly stabilized development properties of $1.0 million; and~~

	•		~~Partially offset by other miscellaneous properties of $1.1 million.~~

Development and other miscellaneous properties in lease-up of $20.2 million;

Properties acquired in 2010 and 2011 of $24.8 million;

Newly stabilized development properties of $2.0 million; and

Partially offset by other miscellaneous properties of $2.3 million.

See also Note 15 in the Notes to Consolidated Financial Statements for additional discussion regarding the ~~Operating Partnership’s~~Company’s segment disclosures.

Fee and asset management revenues, net of fee and asset management expenses, ~~increased~~decreased approximately ~~$0.4~~$0.1 million or ~~84.9%~~5.7% primarily ~~due to a decrease in asset management expenses, partially offset by the loss of fees~~ due to the unwinding of four institutional joint ventures during 2010.

Property management expenses from continuing operations include off-site expenses associated with the self-management of the ~~Operating Partnership’s~~Company’s properties as well as management fees paid to any third party management companies. These expenses increased approximately ~~$1.9~~$2.4 million or ~~9.2%~~5.9%. This increase is primarily attributable to an increase in payroll-related costs, which is largely a result of

the creation of the ~~Operating Partnership’s~~Company’s central business group, which moved certain administrative functions ~~off-site.~~off-site, and increases in education/conference costs and legal and professional fees.

Depreciation expense from continuing operations, which includes depreciation on non-real estate assets, increased approximately ~~$21.9~~$18.2 million or ~~15.0%~~6.0% primarily as a result of additional depreciation expense on properties acquired in 2010 and 2011, development properties placed in service and capital expenditures for all properties owned.

General and administrative expenses from continuing operations, which include corporate operating expenses, increased approximately ~~$0.7~~$1.5 million or ~~6.7%~~7.4% primarily due to an increase in payroll-related costs, which is largely a result of the acceleration of long-term compensation expense for retirement eligible ~~employees.~~employees, and increases in office rent. The ~~Operating Partnership~~Company anticipates that general and administrative expenses will approximate ~~$40.0~~$42.0 million to ~~$42.0~~$43.0 million for the year ending December 31, 2011. The above assumption is based on current expectations and is forward-looking.

Interest and other income from continuing operations decreased approximately ~~$1.2~~$3.6 million or ~~56.2%~~73.3% primarily as a result of insurance/litigation settlement proceeds that occurred induring the ~~quarter~~six months ended ~~March 31,~~June 30, 2010 and did not reoccur induring the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, partially offset by interest earned on cash and cash equivalents and investment securities due to larger overall cash balances during the six months ended June 30, 2011 as compared to the same period in 2010 and forfeited deposits for terminated disposition transactions. The ~~Operating Partnership~~Company anticipates that interest and other income will approximate ~~$2.0~~$1.5 million to ~~$3.0~~$2.0 million for the year ending December 31, 2011. The above assumption is based on current expectations and is forward-looking.

Other expenses from continuing operations ~~decreased~~increased approximately ~~$2.2~~$0.8 million or ~~50.6%~~12.7% primarily due to ~~a decrease in property acquisition costs incurred in conjunction with the Operating Partnership’s lower acquisition volume in 2011, partially offset by~~ an increase in the expensing of overhead (pursuit cost write-offs) as a result of a more active focus on sourcing new development ~~opportunities.~~opportunities, partially offset by a decrease in property acquisition costs incurred in conjunction with the Company’s lower acquisition volume in 2011.

Interest expense from continuing operations, including amortization of deferred financing costs, increased approximately ~~$7.3~~$16.5 million or ~~6.2%~~7.1% as a result of interest expense on the $600.0 million of unsecured notes that closed in July 2010, ~~and~~ lower capitalized interest ~~partially offset by a decrease in financing fees.~~and higher effective interest rates. During the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, the ~~Operating Partnership~~Company capitalized interest costs of approximately ~~$1.7~~$3.7 million as compared to ~~$4.4~~$7.9 million for the ~~quarter~~six months ended ~~March 31,~~June 30, 2010. This capitalization of interest primarily relates to consolidated projects under development. The effective interest cost on all indebtedness for the ~~quarter~~six months ended ~~March 31,~~June 30, 2011 was ~~5.13%~~5.26% as compared to ~~5.22%~~5.14% for the ~~quarter~~six months ended ~~March 31,~~June 30, 2010.

Income and other tax expense from continuing operations ~~was consistent between~~increased $0.4 million as a result of Tennessee franchise tax refunds received during the ~~periods under comparison.~~six months ended June 30, 2010 that did not reoccur during the six months ended June 30, 2011. The ~~Operating Partnership~~Company anticipates that income and other tax expense will approximate $0.5 million to $1.5 million for the year ending December 31, 2011. The above assumption is based on current expectations and is forward-looking.

Loss from investments in unconsolidated entities decreased approximately ~~$0.5~~$0.9 million as compared to the ~~quarter~~six months ended ~~March 31,~~June 30, 2010 primarily due to the unwinding of four institutional joint ventures during 2010.

Net gain on sales of unconsolidated entities decreased approximately ~~$0.5~~$5.6 million primarily due to both the gain on sale and revaluation of seven previously unconsolidated properties that were acquired from the Company’s joint venture partner and the gain on sale for two unconsolidated properties that occurred during the ~~quarter~~six months ended ~~March 31,~~June 30, 2010 ~~that~~and did not reoccur during the ~~quarter~~six months ended ~~March 31,~~June 30, 2011.

Net gain on sales of land parcels increased approximately $4.2 million due to the sale of a land parcel located in suburban Washington D.C. during the six months ended June 30, 2011 as compared to no land sales during the six months ended June 30, 2010.

Discontinued operations, net increased approximately ~~$58.1~~$601.2 million ~~or 86.3%~~ between the periods under comparison. This increase is primarily due to higher gains from property sales during the ~~quarter~~six months ended ~~March 31,~~June 30, 2011 compared to the same period in 2010, partially offset by properties sold in 2011 which reflect operations for none of or a partial period in 2011 in contrast to a full or partial period in 2010. See Note 13 in the Notes to Consolidated Financial Statements for further discussion.

Comparison of the quarter ended June 30, 2011 to the quarter ended June 30, 2010

For the quarter ended June 30, 2011, the Company reported diluted earnings per share/Unit of $1.85 compared to $0.02 per share/Unit in the same period of 2010. The difference is primarily due to higher gains from property sales in 2011 vs. 2010 and higher total property net operating income driven by the positive impact of the Company’s same store and lease-up activity, partially offset by dilution from the Company’s 2010 and 2011 transaction activity.

For the quarter ended June 30, 2011, income from continuing operations increased approximately $31.1 million when compared to the quarter ended June 30, 2010. The increase in continuing operations is discussed below.

Revenues from the Second Quarter 2011 Same Store Properties increased $20.9 million primarily as a result of an increase in average rental rates charged to residents and an increase in occupancy. Expenses from the Second Quarter 2011 Same Store Properties increased $1.2 million primarily due to increases in repairs and maintenance expenses and property management costs, partially offset by decreases in on-site payroll costs.

Non-same store operating results increased approximately $24.2 million and consist primarily of properties acquired in calendar years 2010 and 2011, as well as operations from the Company’s completed development properties. Although the operations of both the non-same store assets and the same store assets have been positively impacted during the quarter ended June 30, 2011, the non-same store assets have contributed a greater percentage of total NOI to the Company’s overall operating results primarily due to 2010 acquisitions, increasing occupancy for properties in lease-up and a longer ownership period in 2011 than 2010.

Newly stabilized development properties of $1.0 million; and

Partially offset by other miscellaneous properties of $1.2 million.

See also Note 15 in the Notes to Consolidated Financial Statements for additional discussion regarding the Company’s segment disclosures.

Fee and asset management revenues, net of fee and asset management expenses, decreased approximately $0.5 million or 34.8% primarily due to the unwinding of four institutional joint ventures during 2010.

Property management expenses from continuing operations 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 $0.5 million or 2.5%. This increase is primarily attributable to an increase in payroll-related costs, which is largely a result of the creation of the Company’s central business group, which moved certain administrative functions off-site and increases in education/conference costs and legal and professional fees.

Depreciation expense from continuing operations, which includes depreciation on non-real estate assets, decreased approximately $3.6 million or 2.2% primarily as a result of a decrease in the amortization of in-place leases due to lower acquisition volume in 2011 compared to 2010.

General and administrative expenses from continuing operations, which include corporate operating expenses, increased approximately $0.8 million or 8.1% primarily due to an increase in payroll-related costs, which is largely a result of the acceleration of long-term compensation expense for retirement eligible employees and increases in office rent.

Interest and other income from continuing operations decreased approximately $2.3 million or 89.3% primarily as a result of insurance/litigation settlement proceeds that occurred in the quarter ended June 30, 2010 and did not reoccur in the quarter ended June 30, 2011, partially offset by interest earned on cash and cash equivalents and investment securities due to larger overall cash balances during the quarter ended June 30, 2011 as compared to the same period in 2010.

Other expenses from continuing operations increased approximately $3.0 million primarily due to an increase in property acquisition costs and an increase in the expensing of overhead (pursuit cost write-offs) as a result of a more active focus on sourcing new development opportunities.

Interest expense from continuing operations, including amortization of deferred financing costs, increased approximately $8.9 million or 7.7% as a result of interest expense on the $600.0 million of unsecured notes that closed in July 2010, lower capitalized interest and higher effective interest rates. During the quarter ended June 30, 2011, the Company capitalized interest costs of approximately $2.0 million as compared to $3.5 million for the quarter ended June 30, 2010. This capitalization of interest primarily relates to consolidated projects under development. The effective interest cost on all indebtedness for the quarter ended June 30, 2011 was 5.39% as compared to 5.06% for the quarter ended June 30, 2010.

Income and other tax expense from continuing operations increased $0.4 million as a result of Tennessee franchise tax refunds received during the quarter ended June 30, 2010 that did not reoccur during the quarter ended June 30, 2011.

Loss from investments in unconsolidated entities decreased approximately $0.5 million as compared to the quarter ended June 30, 2010 primarily due to the unwinding of four institutional joint ventures during 2010.

Net gain on sales of unconsolidated entities decreased approximately $5.1 million primarily due to the gain on sale and revaluation of seven previously unconsolidated properties that were acquired from the Company’s joint venture partner that occurred during the quarter ended June 30, 2010 and did not reoccur during the quarter ended June 30, 2011.

Net gain on sales of land parcels increased approximately $4.2 million due to the sale of a land parcel located in suburban Washington D.C. during the quarter ended June 30, 2011 as compared to no land sales during the quarter ended June 30, 2010.

Discontinued operations, net increased approximately $540.5 million between the periods under comparison. This increase is primarily due to higher gains from property sales during the quarter ended June 30, 2011 compared to the same period in 2010, partially offset by properties sold in 2011 which reflect operations for none of or a partial period in 2011 in contrast to a full or partial period in 2010.

As of January 1, 2011, the ~~Operating Partnership~~Company had approximately $431.4 million of cash and cash equivalents, its restricted 1031 exchange proceeds totaled $103.9 million and it had $1.28 billion available under its revolving credit facility (net of $147.3 million which was restricted/dedicated to support letters of credit and $75.0 million which had been committed by a now bankrupt financial institution and is not available for borrowing). After taking into effect the various transactions discussed in the following paragraphs and the net cash provided by operating activities, the ~~Operating Partnership’s~~Company’s cash and cash equivalents balance at ~~March 31,~~June 30, 2011 was approximately ~~$306.1~~$604.8 million, its restricted 1031 exchange proceeds totaled

~~$212.8~~ $278.9 million and the amount available on ~~the Operating Partnership’s~~its revolving credit facility was $1.34 billion (net of ~~$83.7~~$81.9 million which was restricted/dedicated to support letters of credit and net of the $75.0 million discussed above).

During the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, the ~~Operating Partnership~~Company generated proceeds from various transactions, which included the following:

	•		~~Disposed of 12 consolidated properties, receiving net proceeds of approximately $258.2 million;~~

	•		~~Obtained $0.7 million in new mortgage financing; and~~

Disposed of 38 consolidated properties and one land parcel, receiving net proceeds of approximately $1.2 billion;

	•	~~Issued approximately 4.2 million Units (including EQR Common Shares issued under EQR’s ATM program – see further discussion below) and received net proceeds of $190.0 million.~~

~~During the quarter ended March 31, 2011, the above proceeds were primarily utilized to:~~

Obtained $135.2 million in new mortgage financing; and

	•		~~Acquire two rental properties and a 97,000 square foot commercial building for approximately $123.9 million;~~

	•		~~Invest $29.8 million primarily in development projects; and~~

	•		~~Repay $205.0 million of mortgage loans and $93.1 million of unsecured notes.~~

Issued approximately 5.7 million Common Shares (including Common Shares issued under the ATM program — see further discussion below) and received net proceeds of $241.5 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, 2011, the above proceeds were primarily utilized to:

Acquire seven rental properties, a 97,000 square foot commercial building and one land parcel for approximately $475.4 million;

Invest $63.6 million primarily in development projects; and

Repay $640.8 million of mortgage loans and $93.1 million of unsecured notes.

In September 2009, EQR announced the establishment of an At-The-Market (“ATM”) share offering program which would allow EQR to sell up to 17.0 million Common Shares from time to time over the next three years 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 ~~the Operating Partnership~~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. During the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, EQR issued approximately 3.0 million Common Shares at an average price of $50.84 per share for total consideration of approximately $154.5 million through the ATM ~~share offering~~ program. EQR has not issued any shares under this program since January 13, 2011. Through ~~April~~July 28, 2011, EQR has cumulatively issued approximately 12.7 million Common Shares at an average price of $44.94 per share for total consideration of approximately $570.1 million. Including its February 2011 prospectus supplement which added approximately 5.7 million Common Shares, EQR has 10.0 million Common Shares remaining available for issuance under the ATM program as of ~~March 31,~~July 28, 2011.

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. As of ~~March 31,~~July 28, 2011, EQR had authorization to repurchase $464.6 million of its shares. See Note 3 in the Notes to Consolidated Financial Statements for further discussion.

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

The ~~Operating Partnership’s~~Company’s total debt summary and debt maturity schedules as of ~~March 31,~~June 30, 2011 are as follows:

The ~~Operating Partnership~~Company generally expects to meet its short-term liquidity requirements, including capital expenditures related to maintaining its existing properties and certain scheduled unsecured note and mortgage note repayments, through its working capital, net cash provided by operating activities and borrowings under ~~its~~the Company’s revolving credit facility. Under normal operating conditions, the ~~Operating Partnership~~Company considers its cash provided by operating activities to be adequate to meet operating requirements and payments of distributions. However, there may be times when the ~~Operating Partnership~~Company experiences shortfalls in its coverage of distributions, which may cause the ~~Operating Partnership~~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 ~~Operating Partnership’s~~Company’s financial condition may be adversely affected and it may not be able to maintain its current distribution levels.

During the fourth quarter of 2010, ~~EQR~~the Company announced a new dividend policy which it believes will generate payouts more closely aligned with the actual annual operating results of the ~~Operating Partnership’s~~Company’s core business and provide transparency to investors. ~~EQR and the Operating Partnership intend~~The Company intends to pay an annual cash dividend equal to approximately 65% of Normalized ~~FFO.~~FFO for the year. The ~~Operating Partnership~~Company anticipates the expected dividend payout will be $1.56 to ~~$1.62~~$1.59 per share/Unit ($0.3375 per share/Unit for each of the first three quarters with the balance for the fourth quarter) for the year ending December 31, 2011 to bring the total payment for the year to approximately 65% of Normalized ~~FFO.~~FFO for the year. The above assumption is based on current expectations and is forward-looking. The new dividend policy will lead to a dividend reduction more quickly than in the past should operating results deteriorate and make it less likely that the ~~Operating Partnership~~Company will over distribute. The ~~Operating Partnership~~Company believes that its expected 2011 operating cash flow will be sufficient to cover capital expenditures and distributions.

The ~~Operating Partnership~~Company also expects to meet its long-term liquidity requirements, such as scheduled unsecured note and mortgage debt maturities, property acquisitions, financing of construction and development activities and capital improvements through the issuance of secured and unsecured debt and equity securities, including additional OP Units, and proceeds received from the disposition of certain properties ~~as well as~~and joint ventures. In addition, the ~~Operating Partnership~~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 ~~Operating Partnership~~Company must maintain in order to comply with covenants under its unsecured notes and line of credit. Of the ~~$19.7~~$19.5 billion in investment in real estate on the ~~Operating Partnership’s~~Company’s balance sheet at ~~March 31,~~June 30, 2011, $12.7 billion or ~~64.6%~~65.2% was unencumbered. However, there can be no assurances that these sources of capital will be available to the ~~Operating~~

~~Partnership~~Company in the future on acceptable terms or otherwise.

~~The Operating Partnership’s~~ERPOP’s credit ratings from Standard & Poor’s (“S&P”), Moody’s and Fitch for its outstanding senior debt are BBB+, Baal and BBB+, respectively. EQR’s equity ratings from S&P, Moody’s and Fitch for its outstanding preferred equity are BBB+, Baa2 and BBB-, respectively. During the fourth quarter of 2010, Fitch downgraded ~~the Operating Partnership’s~~ERPOP’s credit rating from A- to BBB+ and EQR’s equity rating from BBB+ to BBB-, which did not have an effect on ~~the Operating Partnership’s~~EQR’s cost of funds. During the first quarter of 2011, Moody’s raised its outlook for both EQR and ~~the Operating Partnership~~ERPOP from negative outlook to stable outlook.

The ~~Operating Partnership has a~~Company’s $1.425 billion (net of $75.0 million which had been committed by a now bankrupt financial institution and is not available for borrowing) long-term revolving credit facility was replaced with a new $1.25 billion unsecured revolving credit facility maturing on July 13, 2014, subject to a one-year extension option exercisable by the Company. The interest rate on advances under the new credit facility will generally be LIBOR plus a spread (currently 1.15%) and the Company pays an annual facility fee of 0.2%. Both the spread and the facility fee are dependent on the credit rating of the Company’s long-term debt. As of July 28, 2011, there was available borrowings as of ~~April 28, 2011 of $1.31~~$1.17 billion (net of ~~$114.1~~$81.9 million which was restricted/dedicated to support letters of credit) on the new revolving credit ~~and net of the $75.0 million discussed above) that matures in February 2012 (see Note 10 in the Notes to Consolidated Financial Statements for further discussion).~~facility. This facility may, among other potential uses, be used to fund property acquisitions, costs for certain properties under development

and short-term liquidity requirements.

In 2010, a portion of the parking garage collapsed at one of the ~~Operating Partnership’s~~Company’s rental properties (Prospect Towers in Hackensack, New Jersey). The ~~Operating Partnership~~Company estimates that the costs related to such collapse (both expensed and capitalized), including providing for residents’ interim needs, lost revenue and garage reconstruction, will be approximately $14.0 million, after insurance reimbursements of $8.0 million. Costs to rebuild the garage are capitalized as incurred. Other costs, like those to accommodate displaced residents, lost revenue due to a portion of the project being temporarily unavailable for occupancy and legal costs, reduce earnings as they are incurred. Generally, insurance proceeds are recorded as increases to earnings as they are received. During the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, the ~~Operating Partnership~~Company received approximately $1.6 million in insurance proceeds which offset expenses of ~~$0.9~~$1.3 million that were recorded relating to this loss and are included in real estate taxes and insurance on the consolidated statements of operations. In addition, the ~~Operating Partnership~~Company estimates that its lost revenues approximated ~~$0.4~~$0.6 million during the ~~quarter~~six months ended ~~March 31,~~June 30, 2011 as a result of lost occupancy in the high-rise tower following the collapse. Through ~~April~~July 28, 2011, the ~~Operating Partnership~~Company has cumulatively received approximately $5.6 million in insurance proceeds which partially offsets expenses of ~~$6.4~~$6.8 million and the ~~Operating Partnership’s~~Company’s estimate of its lost revenues, which approximated ~~$1.9~~$2.1 million. None of the amounts referenced above impact same store results.

See Note 16 in the Notes to Consolidated Financial Statements for discussion of the events which occurred subsequent to ~~March 31,~~June 30, 2011.

Capitalization of Fixed Assets and Improvements to Real Estate

Our policy with respect to capital expenditures is generally to capitalize expenditures that improve the value of the property or extend the useful life of the component asset of the property. We track improvements to real estate in two major categories and several subcategories:

•

Replacements(inside the apartment unit). These include:

	•		~~flooring such as carpets, hardwood, vinyl, linoleum or tile;~~

	•		~~appliances;~~

	•		~~mechanical equipment such as individual furnace/air units, hot water heaters, etc;~~

	•		~~furniture and fixtures such as kitchen/bath cabinets, light fixtures, ceiling fans, sinks, tubs, toilets, mirrors, countertops, etc; and~~

	•		~~blinds/shades.~~

flooring such as carpets, hardwood, vinyl, linoleum or tile;

appliances;

mechanical equipment such as individual furnace/air units, hot water heaters, etc;

furniture and fixtures such as kitchen/bath cabinets, light fixtures, ceiling fans, sinks, tubs, toilets, mirrors, countertops, etc; and

blinds/shades.

All replacements are depreciated over a five to ten-year estimated useful life. We expense as incurred all make-ready maintenance and turnover costs such as cleaning, interior painting of individual apartment units and the repair of any replacement item noted above.

•

Building improvements (outside the apartment unit). These include:

	•		roof replacement and major repairs;

	•		~~paving or major resurfacing of parking lots, curbs and sidewalks;~~

	•		~~amenities and common areas such as pools, exterior sports and playground equipment, lobbies, clubhouses, laundry rooms, alarm and security systems and offices;~~

	•		~~major building mechanical equipment systems;~~

	•		~~interior and exterior structural repair and exterior painting and siding;~~

	•		~~major landscaping and grounds improvement; and~~

paving or major resurfacing of parking lots, curbs and sidewalks;

amenities and common areas such as pools, exterior sports and playground equipment, lobbies, clubhouses, laundry rooms, alarm and security systems and offices;

major building mechanical equipment systems;

interior and exterior structural repair and exterior painting and siding;

major landscaping and grounds improvement; and

vehicles and office and maintenance equipment.

All building improvements are depreciated over a five to ten-year estimated useful life. We capitalize building improvements and upgrades only if the item: (i) exceeds $2,500 (selected projects must exceed $10,000); (ii) extends the useful life of the asset; and (iii) improves the value of the asset.

For the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, our actual improvements to real estate totaled approximately ~~$29.9~~$64.9 million. This includes the following (amounts in thousands except for apartment unit and per apartment unit amounts):

(1)		Total Apartment Units –— Excludes ~~4,805~~4,850 military housing apartment units for which repairs and maintenance expenses and capital expenditures to real estate are self-funded and do not consolidate into the ~~Operating Partnership’s~~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 ~~$8.9~~$18.2 million spent ~~in Q1~~during the six months ended June 30, 2011 on apartment unit renovations/rehabs (primarily kitchens and baths) on ~~1,132~~2,497 apartment units (equating to about ~~$7,900~~$7,300 per apartment unit rehabbed) designed to reposition these assets for higher rental levels in their respective markets.

(3)		Same Store Properties –— Primarily includes all properties acquired or completed and stabilized prior to January 1, 2010, less properties subsequently sold.

(4)		Non-Same Store Properties –— Primarily includes all properties acquired during 2010 and 2011, plus any properties in lease-up and not stabilized as of January 1, 2010. Per apartment unit amounts are based on a weighted average of ~~10,137~~10,369 apartment units.

(5)		Other –— Primarily includes expenditures for properties sold during the period.

For 2011, the ~~Operating Partnership~~Company estimates that it will spend approximately $1,200 per apartment unit of capital expenditures for its same store properties inclusive of apartment unit renovation/rehab costs, or $850 per apartment unit excluding apartment unit renovation/rehab costs. For 2011, the ~~Operating Partnership~~Company estimates that it will spend $41.0 million rehabbing 5,500 apartment units (equating to about $7,500 per apartment unit rehabbed). The above assumptions are based on current expectations and are forward-looking.

During the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, the ~~Operating Partnership’s~~Company’s total non-real estate capital additions, such as computer software, computer equipment, and furniture and fixtures and leasehold improvements to the ~~Operating Partnership’s~~Company’s property management offices and its corporate offices, were approximately ~~$2.7~~$4.0 million. The ~~Operating Partnership~~Company expects to fund approximately ~~$5.8~~$4.5 million in total additions to non-real estate property for the remainder of 2011. The above assumption is based on current expectations and is forward-looking.

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

Derivative Instruments

The ~~Operating Partnership~~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 ~~Operating Partnership~~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.

See Note 11 in the Notes to Consolidated Financial Statements for additional discussion of derivative instruments at

~~March 31,~~ June 30, 2011.

Other

Total distributions paid in ~~April~~July 2011 amounted to ~~$106.4~~$107.0 million (excluding distributions on Partially Owned Properties), which included certain distributions declared during the ~~first~~second quarter ended ~~March 31,~~June 30, 2011.

Off-Balance Sheet Arrangements and Contractual Obligations

In 2010, the ~~Operating Partnership~~Company admitted an 80% institutional partner to an entity owning a developable land parcel in Florida in exchange for $11.7 million in cash and retained a 20% equity interest. This land parcel is now unconsolidated. Total project cost is approximately ~~$76.1~~$78.2 million and construction ~~is expected to start in~~will be predominantly funded with a long-term, non-recourse secured loan from the ~~second quarter of 2011.~~partner. The ~~Operating Partnership~~Company is responsible for constructing the project and has given certain construction cost overrun guarantees. The ~~Operating Partnership’s~~Company’s remaining funding obligation is currently estimated at approximately ~~$2.3~~$2.4 million. The ~~Operating Partnership’s~~Company’s strategy with respect to this venture was to reduce its financial risk related to the development of this property. However, management does not believe that this investment has a materially different impact upon the ~~Operating Partnership’s~~Company’s liquidity, cash flows, capital resources, credit or market risk than its other consolidated development activities.

As of ~~March 31,~~June 30, 2011, the ~~Operating Partnership~~Company has four consolidated projects totaling 747 apartment units and one unconsolidated project totaling 501 apartment units in various stages of development with estimated completion dates ranging through September 30, 2013, as well as other completed development projects that are in various stages of lease up or are stabilized. The development agreements currently in place are discussed in detail in Note 14 of the ~~Operating Partnership’s~~Company’s Consolidated Financial Statements.

See also Notes 2 and 6 in the Notes to Consolidated Financial Statements for additional discussion regarding the ~~Operating Partnership’s~~Company’s investments in partially owned entities.

The ~~Operating Partnership’s~~Company’s contractual obligations for the next five years and thereafter have not changed materially from the amounts and disclosures included in ~~its~~each of the Company’s and the Operating Partnership’s annual ~~report~~reports on Form 10-K, other than as it relates to scheduled debt maturities. See the updated debt maturity schedule included in Liquidity and Capital Resources for further discussion.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to use judgment in the application of accounting policies, including making estimates and assumptions. If our judgment or interpretation of the facts and circumstances relating to various transactions had been different or different assumptions were made, it is possible that different accounting policies would have been applied, resulting in different financial results or different presentation of our financial statements.

The ~~Operating Partnership~~Company has identified five significant accounting policies as critical accounting policies. These critical accounting policies are those that have the most impact on the reporting of our financial condition and those requiring significant judgments and estimates. With respect to these critical accounting policies, management believes that the application of judgments and estimates is consistently applied and produces financial information that fairly presents the results of operations for all periods presented. The five critical accounting policies are:

Acquisition of Investment Properties

The ~~Operating Partnership~~Company allocates the purchase price of properties to net tangible and identified intangible assets acquired based on their fair values. In making estimates of fair values for purposes of allocating purchase price, the ~~Operating Partnership~~Company utilizes a number of sources, including independent appraisals that may be obtained in connection with the acquisition or financing of the respective property, our own analysis of recently acquired and existing comparable properties in our portfolio and other market data. The ~~Operating Partnership~~Company also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the fair value of the tangible and intangible assets acquired.

Impairment of Long-Lived Assets

The ~~Operating Partnership~~Company periodically evaluates its long-lived assets, including its investments in real estate, for indicators of impairment. The judgments regarding the existence of impairment indicators are based on factors such as operational performance, market conditions and legal and environmental concerns, as well as the ~~Operating~~

~~Partnership’s~~Company’s ability to hold and its intent with regard to each asset. Future events could occur which would cause the ~~Operating Partnership~~Company to conclude that impairment indicators exist and an impairment loss is warranted.

Depreciation of Investment in Real Estate

The ~~Operating Partnership~~Company depreciates the building component of its investment in real estate over a 30-year estimated useful life, building improvements over a 5-year to 10-year estimated useful life and both the furniture, fixtures and equipment and replacements components over a 5-year to 10-year estimated useful life, all of which are judgmental determinations.

Cost Capitalization

See theCapitalization of Fixed Assets and Improvements to Real Estatesection for a discussion of the ~~Operating Partnership’s~~Company’s policy with respect to capitalization vs. expensing of fixed asset/repair and maintenance costs. In addition, the ~~Operating Partnership~~Company capitalizes an allocation of the payroll and associated costs of employees directly responsible for and who spend their time on the supervision of major capital and/or renovation projects. These costs are reflected on the balance sheet as an increase to depreciable property.

For all development projects, the ~~Operating Partnership~~Company uses its professional judgment in determining whether such costs meet the criteria for capitalization or must be expensed as incurred. The ~~Operating Partnership~~Company capitalizes interest, real estate taxes and insurance and payroll and associated costs for those individuals directly responsible for and who spend their time on development activities, with capitalization ceasing no later than 90 days following issuance of the certificate of occupancy. These costs are reflected on the balance sheet as construction-in-progress for each specific property. The ~~Operating Partnership~~Company expenses as incurred all payroll costs of on-site employees working directly at our properties, except as noted above on our development properties prior to certificate of occupancy issuance and on specific major renovations at selected properties when additional incremental employees are hired.

Funds From Operations and Normalized Funds From Operations

For the ~~quarter~~six months ended ~~March 31,~~June 30, 2011, Funds From Operations (“FFO”) available to Common Shares and Units / Units and Normalized FFO available to Common Shares and Units / Units increased ~~$28.0~~$33.9 million, or ~~19.3%~~10.6%, and ~~$24.9~~$36.6 million, or ~~16.6%~~11.3%, respectively, as compared to the six months ended June 30, 2010.

For the quarter ended June 30, 2011, FFO available to Common Shares and Units / Units and Normalized FFO available to Common Shares and Units / Units increased $5.9 million, or 3.4%, and $11.7 million, or 6.7%, respectively, as compared to the quarter ended ~~March 31,~~June 30, 2010.

(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 of depreciable property, 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. Once the ~~Operating Partnership~~Company commences the conversion of apartment units to condominiums, it simultaneously discontinues depreciation of such property.

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

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

	•		property acquisition and other transaction costs related to mergers and acquisitions and pursuit cost write-offs (other expenses);

	•		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 and condominium sales, net of the effect of income tax benefits or expenses; and

	•		other miscellaneous non-comparable items.


(3)		The ~~Operating Partnership~~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 ~~Operating Partnership~~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 ~~Operating Partnership’s~~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 ~~Operating Parntership’s~~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 accounting principles generally accepted in the United States. 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 2.		Unregistered Sales of Equity Securities and Use of Proceeds

(a) Unregistered Common Shares Issued in the Quarter Ended June 30, 2011 — Equity Residential

During the quarter ended June 30, 2011, EQR issued 260,790 Common Shares in exchange for 260,790 OP Units held by various limited partners of the Operating Partnership. OP Units are generally exchangeable into Common Shares on a one-for-one basis or, at the option of the Operating Partnership, the cash equivalent thereof, at any time one year after the date of issuance. These shares were either registered under the Securities Act of 1933, as amended (the “Securities Act”), or issued in reliance on an exemption from registration under Section 4(2) of the Securities Act and the rules and regulations promulgated thereunder, as these were transactions by an issuer not involving a public offering. In light of the manner of the sale and information obtained by EQR from the limited partners in connection with these transactions, EQR believes it may rely on these exemptions.
