ERP OPERATING LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.	1.Business

ERP Operating Limited Partnership (“ERPOP”), an Illinois limited partnership, was formed in May 1993 to conduct the multifamily residential property business of Equity Residential (“EQR”). EQR, a Maryland real estate investment trust (“REIT”) formed in March 1993, is an S&P 500 company focused on the acquisition, development and management of high quality apartment properties in top United States growth markets. EQR has elected to be taxed as a REIT.

EQR is the general partner of, and as of ~~March 31,~~June 30, 2008 owned an approximate 93.8% ownership interest in ERPOP. EQR is structured as an umbrella partnership REIT (“UPREIT”), under which all property ownership and business operations are conducted through ERPOP and its subsidiaries. References to the “Operating Partnership” include ERPOP and those entities owned or controlled by it. References to the “Company” mean EQR and the Operating Partnership.

As of ~~March 31,~~June 30, 2008, the Operating Partnership, directly or indirectly through investments in title holding entities, owned all or a portion of ~~565~~564 properties in 2423 states and the District of Columbia consisting of ~~149,769~~150,699 units. The ownership breakdown includes (table does not include various uncompleted development properties):

2.	Summary of Significant Accounting Policies

2.~~Summary of Significant Accounting Policies~~

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) and certain reclassifications considered necessary for a fair presentation have been included. Certain reclassifications have been made to the prior period financial statements in order to conform to the current year presentation. Operating results for the ~~quarter~~six months ended ~~March 31,~~June 30, 2008 are not necessarily indicative of the results that may be expected for the year ending December 31, 2008.

In preparation of the Operating Partnership’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 at December 31, 2007 has 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.

net income attributable to the parent and to the noncontrolling interest. This statement is effective for the

10

Operating Partnership on January 1, 2009. The Operating Partnership is currently evaluating the impact SFAS No. 160 will have on its consolidated results of operations and financial position.

In March 2008, the FASB issued SFAS No. 161,Disclosures about Derivative Instruments and Hedging Activities – an amendment of FASB Statement No. 133. SFAS No. 161 is intended to improve financial standards for derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entity’s financial position, financial performance, and cash flows. Among other requirements, entities are required to provide enhanced disclosures about: (1) how and why an entity uses derivative instruments; (2) how derivative instruments and related hedged items are accounted for under SFAS No. 133 and its related interpretations; and (3) how derivative instruments and related hedged items affect an entity’s financial position, financial performance and cash flows. SFAS No. 161 is effective for the Operating Partnership on January 1, 2009. The Operating Partnership is currently evaluating the impact SFAS No. 161 will have on its consolidated financial statements.

In May 2008, the FASB issued FSP No. APB 14-1,Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement) (“APB 14-1”). APB 14-1 requires the issuer of certain convertible debt instruments that may be settled in cash on conversion to separately account for the liability and equity components of the instrument in a manner that reflects the issuer’s nonconvertible debt borrowing rate. APB 14-1, which is applied retrospectively, is effective for the Operating Partnership beginning January 1, 2009. While the Operating Partnership is currently evaluating the impact APB 14-1 will have on its consolidated financial statements, it is likely to result in an increase to interest expense for all periods since the Operating Partnership issued its convertible notes in August 2006.

These shares were retired subsequent to the repurchases. Concurrent with these transactions, the Operating Partnership repurchased and retired 171,161 OP Units previously issued to EQR. Of the total shares repurchased, 71,161 shares were repurchased from employees at an average price of $38.25 per share (the average of the then current market prices) to cover the minimum statutory tax withholding obligations related to the vesting of employees’ restricted shares. The remaining 100,000 shares were repurchased in the open market at an average price of $35.74 per share. The Company also funded $4.6 million in January 2008 for the settlement of 125,000 Common Shares that were repurchased in December 2007 and recorded as other liabilities at December 31, 2007. EQR has authorization to repurchase an additional $469.3 million of its shares as of ~~March 31,~~June 30, 2008.

The Limited Partners of the Operating Partnership as of ~~March 31,~~June 30, 2008 include various individuals and entities that contributed their properties to the Operating Partnership in exchange for OP Units. Subject to

11

certain restrictions, the Limited Partners may exchange their OP Units for EQR Common Shares on a one-for-one basis.

EQR contributes all net proceeds from its various equity offerings (including proceeds from exercise of options for EQR Common Shares) to the Operating Partnership. 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).

~~10.~~~~Lines of Credit~~

TheThe Operating Partnership has an unsecured revolving credit facility with potential borrowings of up to $1.5 billion maturing on February 28, 2012, with the ability to increase available borrowings by an additional $500.0 million by adding additional banks to the facility or obtaining the agreement of existing banks to increase their commitments. Advances under the credit facility bear interest at variable rates based upon LIBOR at various interest periods plus a spread dependent upon the Operating Partnership’s credit rating or based on bids received from the lending group. EQR has guaranteed the Operating Partnership’s credit facility up to the maximum amount and for the full term of the facility.

As of ~~March 31,~~June 30, 2008, no amounts were outstanding and ~~$77.5~~$74.0 million was restricted (dedicated to support letters of credit and not available for borrowing) on the credit facility. During the ~~quarter~~six months ended ~~March 31,~~June 30, 2008, the weighted average interest rate under the credit facility was 4.29%.

(1) Fair Value Hedges – Converts outstanding fixed rate debt to a floating interest rate.

(2) Forward Starting Swaps – Designed to partially fix the interest rate in advance of a planned future debt issuance.

(3) Development Cash Flow Hedges – Converts outstanding floating rate debt to a fixed interest rate.

On ~~March~~ 31, June 30, 2008, the net derivative instruments were reported at their fair value as other liabilities of approximately ~~$5.2~~$3.4 million and other assets of ~~$5.0~~$3.2 million. As of ~~March 31,~~June 30, 2008, there were approximately ~~$25.1~~$20.5 million in deferred losses, net, included in accumulated other comprehensive loss. Based on the estimated fair values of the net derivative instruments at ~~March 31,~~June 30, 2008, the Operating Partnership may recognize an

16

estimated ~~$5.7~~$5.0 million of accumulated other comprehensive loss as additional interest expense during the twelve months ending ~~March 31,~~June 30, 2009.

In February 2008, the Operating Partnership paid approximately $13.2 million to terminate three forward starting swaps in conjunction with the issuance of a $500.0 million 11.5 year mortgage loan. The entire amount has been deferred as a component of accumulated other comprehensive loss and will be recognized as an increase to interest expense over the first ten years of the mortgage loan.

SFAS No. 157 establishes a three-level valuation hierarchy 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.~~

16Level 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 Operating Partnership’s derivative positions are valued using models developed by the respective counterparty as well as models developed internally by the Operating Partnership that use as their basis readily observable market parameters (such as forward yield curves and credit default swap data) and are classified within Level 2 of the valuation hierarchy. In addition, employee holdings other than EQR Common Shares within the supplemental executive retirement plan (the “SERP”) have a fair value of ~~$54.7~~$60.6 million as of ~~March 31,~~June 30, 2008 and are included in other assets and other liabilities on the consolidated balance sheet. These SERP investments are valued using quoted market prices for identical assets and are classified within Level 1 of the valuation hierarchy.

14.
Commitments and Contingencies                               ~~Commitments and Contingencies~~
The Operating Partnership, as an owner of real estate, is subject to various Federal, state and local environmental laws. Compliance by the Operating Partnership with existing laws has not had a material adverse effect on the Operating Partnership. However, the Operating Partnership 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 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 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 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. Accordingly, the Operating Partnership is defending the suit vigorously.
19
Due to the pendency of the Operating Partnership’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 and as a result, no amounts have been accrued at ~~March 31,~~June 30, 2008. While no assurances can be given, the Operating Partnership does not believe that the suit, if adversely determined, would have a material adverse effect on the Operating Partnership.
The Operating Partnership does not believe there is any other litigation pending or threatened against it that, individually or in the aggregate, reasonably may be expected to have a material adverse effect on the Operating Partnership.
The Operating Partnership 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 periodically assesses the adequacy of the reserve and makes adjustments as necessary. During the six months ended June 30, 2008, the Operating Partnership recorded additional reserves of approximately $0.2 million for current projects and $3.2 million for various projects sold prior to 2008 and paid approximately $0.3 million in settlements. As a result, the Operating Partnership had total reserves of approximately $10.5 million at June 30, 2008. While no assurances can be given, the Operating Partnership does not believe that the ultimate resolution of these potential liabilities, if adversely determined, would have a material adverse effect on the Operating Partnership.
During the years ended December 31, 2005 and 2004, the Operating Partnership established a reserve and recorded a corresponding expense, net of insurance receivables, for estimated uninsured property damage at certain of its properties caused by various hurricanes in each respective year. During the ~~quarter~~six months ended ~~March 31,~~June 30, 2008, the Operating Partnership received the remaining accrued receivable of $1.8 million. As of ~~March 31,~~June 30, 2008, the remaining reserve balance is ~~$0.7~~$0.3 million and is included in other liabilities on the consolidated balance sheets.
As of ~~March 31,~~June 30, 2008, the Operating Partnership has 1311 projects totaling ~~4,484~~3,733 units in various stages of development with estimated completion dates ranging through June 30, 2011. Some of the projects are developed solely by the Operating Partnership, while others are 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 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). However, the buy-sell provisions with one partner covering three projects does require the Operating Partnership to purchase the partner’s interest in the projects at fair market value five years following the receipt of the final certificate of occupancy on the last developed property (in Q1 2009).
~~15.~~                               ~~Reportable Segments~~

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.
19

The Operating Partnership’s primary business is owning, managing, and operating multifamily residential properties, which include 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 operating segments have been aggregated by geography in a manner identical to
20
that which is provided to its chief operating decision maker.
The Operating Partnership’s fee and asset management, development (including FIN No. 46 partially owned properties), 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 as provided for in SFAS No. 131 and as such, have been aggregated 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 total revenues during the six months and quarters ended ~~March 31,~~June 30, 2008 and 2007, respectively.
The primary financial measure for the Operating Partnership’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 believes that NOI is helpful to investors as a supplemental measure of the operating performance of a real estate company because it is a direct measure of the actual operating results of the Operating Partnership’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 ~~table presents~~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, 2008 and 2007, respectively, as well as total assets ~~for the quarter ended March 31,~~at June 30, 2008 (amounts in thousands):

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
For further information including definitions for capitalized terms not defined herein, refer to the consolidated financial statements and footnotes thereto included in the Operating Partnership’s annual report on Form 10-K for the year ended ~~December31,~~December 31, 2007.
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 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 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 ~~assumes~~undertakes no obligation to update or supplement these forward-looking ~~statements because of subsequent events.~~statements. Factors that might cause such differences include, but are not limited to the following:

—
·We intend to actively acquire and develop multifamily properties for rental operations and/or conversion into condominiums, as well as upgrade and sell existing properties as individual condominiums. We may underestimate the costs necessary to bring an acquired or development property up to standards established for its intended market position. 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 efforts. This competition may increase prices for multifamily properties or decrease the price at which we expect to sell individual properties. We may not be in a position or have the opportunity in the future to make suitable property acquisitions on favorable terms. We also plan to develop more properties ourselves in addition to co-investing with our development partners for either the rental or condominium market, depending on opportunities in each submarket. This may increase the overall level of risk associated with our developments. The total number of development units, cost 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;
·                  ~~Sources of capital to the Operating Partnership or labor and materials required for maintenance, repair, capital expenditure or development are 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 of multifamily housing, slow employment growth, availability of low interest mortgages for single-family home buyers and the potential for geopolitical instability, all of which are beyond the Operating Partnership’s control; and
·                  ~~Additional factors as discussed in Part I of the Annual Report on Form 10-K, particularly those under “Risk Factors”.~~

EQR, a Maryland real estate investment trust (“REIT”) formed in March 1993, is an S&P 500 company focused on the acquisition, development and management of high quality apartment properties in top United States growth markets. EQR has elected to be taxed as a REIT.
EQR is one of the largest publicly traded real estate companies and is the largest publicly traded owner of multifamily properties (based on the aggregate market value of its outstanding Common Shares, the number of apartment units wholly owned and total revenues earned). The Operating Partnership’s corporate headquarters are located in Chicago, Illinois and the Operating Partnership also operates ~~approximately 35~~ property management offices throughout the United States. The Operating Partnership has approximately ~~4,700~~4,800 employees who provide real estate operations, leasing, legal, financial, accounting, acquisition, disposition, development and other support functions.
Business Objectives and Operating Strategies
The Operating Partnership seeks to maximize current income, capital appreciation of each property and the total return for its shareholders. The Operating Partnership’s strategy for accomplishing these objectives includes:

—
·Leveraging our size and scale in four critical ways:

—
·Investing in apartment communities located in strategically targeted markets, to maximize our total return on an enterprise level;
·~~Meeting the needs of our residents by offering a wide array of product choices and a commitment to service;~~
·~~Engaging, retaining, and attracting the best employees by providing them with the education, resources and opportunities to succeed; and~~
·~~Sharing resources, customers and best practices in property management and across the enterprise.~~

Acquisition, Development and Disposition Strategies
The Operating Partnership anticipates that future property acquisitions, developments and dispositions will occur within the United States. 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, joint venture agreements and collateralized and uncollateralized borrowings. In addition, the

2426

Operating Partnership 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. In addition, ERPOP may acquire or develop multifamily properties specifically to convert directly into condominiums as well as upgrade and sell existing properties as individual condominiums. ERPOP may also acquire land parcels to hold and/or sell based on market opportunities.
When evaluating potential acquisitions, developments and dispositions, the Operating Partnership generally considers the following factors:

—
strategically targeted markets;
—
income levels and employment growth trends in the relevant market;
—
employment and household growth and net migration of the relevant market’s population;
—
barriers to entry that would limit competition (zoning laws, building permit availability, supply of undeveloped or developable real estate, local building costs and construction costs, among other factors);
—
the location, construction quality, condition and design of the property;
—
the current and projected cash flow of the property and the ability to increase cash flow;
—
the potential for capital appreciation of the property;
—
the terms of resident leases, including the potential for rent increases;
—
the potential for economic growth and the tax and regulatory environment of the community in which the property is located;
—
the occupancy and demand by residents for properties of a similar type in the vicinity (the overall market and submarket);
—
the prospects for liquidity through sale, financing or refinancing of the property;
—
the benefits of integration into existing operations;
—
purchase prices and yields of available existing stabilized properties, if any;
—
competition from existing multifamily properties, residential properties under development and the potential for the construction of new multifamily properties in the area; and
—
opportunistic selling based on demand and price of high quality assets, including condominium conversions.

·~~opportunistic selling based on demand and price of high quality assets, including condominium conversions.~~
The Operating Partnership generally reinvests the proceeds received from property dispositions primarily to achieve its acquisition and development strategies and at times to fund its share repurchase activities. In addition, when feasible, the Operating Partnership may structure these transactions as tax-deferred exchanges.
Current Environment
The increasing slowdown in the economy coupled with continued job losses and/or lack of job growth leads us to be cautious regarding expected performance for the remainder of 2008. Revenue growth may moderate in most of our major markets if the economic slowdown continues to impact existing and prospective residents. Markets with little employment loss should perform better than markets with employment issues caused by the single family home crisis.
Results of Operations
In conjunction with our business objectives and operating strategy, the Operating Partnership has continued to invest or recycle its capital investment in apartment communities located in strategically targeted markets during the ~~quarter~~six months ended ~~March~~ 31,June 30, 2008. In summary, we:

·~~Acquired $41.9 million of properties consisting of 2 properties and 171 units, both of which we deem to be in our strategic targeted markets; and~~27
·~~Sold $271.6 million of properties consisting of 15 properties and 3,317 units, as well as 41 condominium units for $9.4 million.~~
—
Acquired $336.9 million of properties consisting of 6 properties and 1,837 units and an uncompleted development property for $31.7 million, all of which we deem to be in our strategic targeted markets; and
—
Sold $478.5 million of properties consisting of 23 properties and 5,282 units, as well as 73 condominium units for $15.5 million.
The Operating Partnership’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
25

Partnership believes that NOI is helpful to investors as a supplemental measure of the operating performance of a real estate company because it is a direct measure of the actual operating results of the Operating Partnership’s apartment communities.
Properties that the Operating Partnership owned for all of both of the six months ended June 30, 2008 and 2007 (the “Six-Month 2008 Same Store Properties”), which represented 119,546 units, and properties that the Operating Partnership owned for all of both of the quarters ended ~~March 31,~~June 30, 2008 and 2007 (the ~~“First~~“Second Quarter 2008 Same Store Properties”), which represented ~~121,826~~123,246 units, impacted the Operating Partnership’s results of operations. ~~The First~~Both the Six-Month 2008 Same Store Properties and the Second Quarter 2008 Same Store Properties are discussed in the following paragraphs.
The Operating Partnership’s acquisition, disposition and completed development activities also impacted overall results of operations for the six months and quarters ended ~~March~~ ~~31,~~June 30, 2008 and 2007. 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, 2008 to the ~~quarter~~six months ended ~~March 31,~~June 30, 2007
For the ~~quarter~~six months ended ~~March~~ 31,June 30, 2008, income from continuing operations increased by approximately ~~$18.5~~$47.7 million when compared to the ~~quarter~~six months ended ~~March~~ 31,June 30, 2007. The increase in continuing operations is discussed below.
Revenues from the ~~First Quarter~~Six-Month 2008 Same Store Properties increased ~~$15.2~~$32.3 million primarily as a result of higher rental rates charged to residents. Expenses from the ~~First Quarter~~Six-Month 2008 Same Store Properties increased ~~$2.7~~$6.4 million primarily due to higher utilities, payroll and real estate taxes.

For properties that the Operating Partnership acquired prior to January 1, 2007 and expects to continue to own through December 31, 2008, the Operating Partnership anticipates the following same store results for the full year ending December 31, 2008:

~~2.50%~~2.25% to ~~3.25%~~
2.50%
NOI change
~~3.00%~~3.50% to ~~4.75%~~
4.00%
These 2008 assumptions are based on current expectations and are forward-looking.
Non-same store operating results increased ~~$23.9~~$42.5 million and consist primarily of properties acquired in calendar years 2008 and 2007 as well as operations from completed development properties and our corporate housing business.
See also Note 15 in the Notes to Consolidated Financial Statements for additional discussion regarding the Operating Partnership’s segment disclosures.
Fee and asset management revenues, net of fee and asset management expenses, increased ~~$0.2~~$0.6 million primarily due to an increase in revenue earned on the management of our military housing venture at Fort Lewis, ~~as well as~~partially offset by a decrease in asset management expenses from managing fewer properties for third parties and unconsolidated entities. As of ~~March 31,~~June 30, 2008 and 2007, the Operating Partnership managed 14,472 and ~~15,025~~15,086 units, respectively, primarily for unconsolidated entities and our military housing venture at Fort Lewis.
Property management expenses from continuing operations include off-site expenses associated with the self-management of the Operating Partnership’s properties as well as management fees paid to any third party management companies. These expenses decreased by approximately ~~$3.7~~$6.7 million or ~~14.8%~~14.1%. This decrease is primarily attributable to lower overall payroll-related costs as a result of a decrease in the number of properties in the Operating Partnership’s portfolio, as well as a decrease in ~~third party management~~legal and professional fees.
Depreciation expense from continuing operations, which includes depreciation on non-real estate assets, increased ~~$7.7~~$9.7 million primarily as a result of additional depreciation expense on properties acquired in 2007 and 2008 and capital expenditures for all properties owned.
General and administrative expenses from continuing operations, which include corporate operating expenses, increased ~~$3.1~~$3.4 million primarily as a result of a ~~$1.7~~$2.2 million increase in severance related costs in 2008 (see Note 16) as well as a ~~$1.6~~$1.7 million expense recovery recorded for the ~~quarter~~six months ended ~~March 31,~~June 30, 2007 related to a certain lawsuit in Florida. The Operating Partnership anticipates that general and
29
administrative expenses will approximate ~~$48.0~~$46.0 million to ~~$50.0~~$48.0 million for the year ending December 31, 2008. The above assumption is based on current expectations and is forward-looking.
Impairment from continuing operations ~~decreased $0.1~~increased $0.3 million primarily as a result of an increase in the ~~write-off~~write-offs of various pursuit and out-of-pocket costs for a terminated development ~~transaction~~transactions during the ~~quarter~~six months ended ~~March 31, 2007, partially offset by the write-off of various deferred sales costs on halted condominium conversions during the quarter ended March 31, 2008~~
June 30, 2008.
Interest and other income from continuing operations increased ~~$0.9~~$2.0 million primarily as a result of an increase in ~~forfeited deposits and~~ insurance/litigation settlement proceeds and forfeited deposits, partially offset by a decrease in interest on cash and restricted deposits. The Operating Partnership anticipates that interest and other income will approximate ~~$5.0~~$12.5 million to ~~$10.0~~$14.5 million for the year ending December 31, 2008. The above assumption is based on current expectations and is forward-looking.
27

Interest expense from continuing operations, including amortization of deferred financing costs, increased approximately ~~$6.5~~$0.8 million primarily as a result of higher overall debt levels outstanding due to the Company’s 2007 share repurchase activity and its pre-funding of its 2008 debt maturities, partially offset by a reduction of debt extinguishment costs and lower overall effective interest rates. During the ~~quarter~~six months ended ~~March~~ 31,June 30, 2008, the Operating Partnership capitalized interest costs of approximately ~~$14.7~~$29.5 million as compared to ~~$7.9~~$17.9 million for the ~~quarter~~six months ended ~~March 31,~~June 30, 2007. 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, 2008 was ~~5.61%~~5.55% as compared to ~~5.93%~~6.02% for the ~~quarter~~six months ended ~~March~~ 31,June 30, 2007. The Operating Partnership anticipates that interest expense (including discontinued operations) will approximate ~~$470.0~~$475.0 million to ~~$490.0~~$485.0 million for the year ending December 31, 2008. The above assumption is based on current expectations and is forward-looking.
Income and other tax expense from continuing operations increased ~~$2.3~~$3.9 million primarily due to a change in the estimate for Texas state taxes and an increase in franchise taxes. The Operating Partnership anticipates that income and other tax expense will approximate $5.0 million to $6.0 million for the year ending December 31, 2008. The above assumption is based on current expectations and is forward-looking.
Loss from investments in unconsolidated entities decreased ~~$0.1~~$0.2 million as compared to the ~~quarter~~six months ended ~~March 31,~~June 30, 2007 due to improved operating performance at the Operating Partnership’s partially owned unconsolidated entities.
Net gain on sales of land parcels decreased $4.5 million as a result of the sale of one vacant land parcel during the six months ended June 30, 2007 versus no sales occurring during the six months ended June 30, 2008.
Discontinued operations, net decreased approximately ~~$3.0~~$192.0 million between the periods under comparison. This decrease is primarily due to the number and mix of ~~those~~ properties sold during the ~~quarter~~six months ended ~~March 31,~~June 30, 2008 as compared to the same period in 2007 and the operations of those properties. See Note 13 in the Notes to Consolidated Financial Statements for further discussion.
Comparison of the quarter ended June 30, 2008 to the quarter ended June 30, 2007
For the quarter ended June 30, 2008, income from continuing operations increased by approximately $29.6 million when compared to the quarter ended June 30, 2007. The increase in continuing operations is discussed below.
Revenues from the Second Quarter 2008 Same Store Properties increased $17.6 million primarily as a result of higher rental rates charged to residents. Expenses from the Second Quarter 2008 Same Store Properties increased $3.9 million primarily due to higher utilities and real estate taxes.

See also Note 15 in the Notes to Consolidated Financial Statements for additional discussion regarding the Operating Partnership’s segment disclosures.
Fee and asset management revenues, net of fee and asset management expenses, increased $0.5 million during the quarter ended June 30, 2008 primarily due to an increase in revenue earned on the management of our military housing venture at Fort Lewis, partially offset by a decrease in asset management expenses from managing fewer properties for third parties and unconsolidated entities.
Property management expenses from continuing operations include off-site expenses associated with the self-management of the Operating Partnership’s properties as well as management fees paid to any third party management companies. These expenses decreased by approximately $3.0 million or 13.2%. This decrease is primarily attributable to lower overall payroll-related costs as a result of a decrease in the number of properties in the Operating Partnership’s portfolio, as well as a decrease in legal and professional fees.
Depreciation expense from continuing operations, which includes depreciation on non-real estate assets, increased $2.0 million primarily as a result of additional depreciation expense on properties acquired in 2007 and 2008, as well as capital expenditures for all properties owned.
31
General and administrative expenses from continuing operations, which include corporate operating expenses, increased $0.3 million primarily as a result of a $0.5 million increase in severance related costs in 2008 (see Note 16).
Impairment from continuing operations increased $0.4 million primarily as a result of an increase in the write-offs of various pursuit and out-of-pocket costs for terminated development transactions during the quarter ended June 30, 2008.
Interest and other income from continuing operations increased $1.0 million primarily as a result of $1.2 million received during the quarter ended June 30, 2008 for the settlement of an eminent domain case with the state of California.
Interest expense from continuing operations, including amortization of deferred financing costs, decreased approximately $5.7 million primarily due to a reduction of debt extinguishment costs and lower overall effective interest rates, partially offset by higher overall debt levels outstanding due to the Company’s 2007 share repurchase activity and its pre-funding of its 2008 debt maturities. During the quarter ended June 30, 2008, the Operating Partnership capitalized interest costs of approximately $14.8 million as compared to $10.0 million for the quarter ended June 30, 2007. This capitalization of interest primarily relates to consolidated projects under development. The effective interest cost on all indebtedness for the quarter ended June 30, 2008 was 5.47% as compared to 6.10% for the quarter ended June 30, 2007.
Income and other tax expense from continuing operations increased $1.5 million primarily due to a change in the estimate for Texas state taxes and an increase in franchise taxes.
Loss from investments in unconsolidated entities was consistent between the periods under comparison.
Net gain on sales of land parcels decreased $4.5 million as a result of the sale of one vacant land parcel during the quarter ended June 30, 2007 versus no sales occurring during the quarter ended June 30, 2008.
Discontinued operations, net decreased approximately $189.4 million between the periods under comparison. This decrease is primarily due to the number and mix of properties sold during the quarter ended June 30, 2008 as compared to the same period in 2007 and the operations of those properties. See Note 13 in the Notes to Consolidated Financial Statements for further discussion.
Liquidity and Capital Resources
As of January 1, 2008, the Operating Partnership had approximately $50.8 million of cash and cash equivalents and $1.3 billion available under its revolving credit facility (net of $80.8 million which was restricted/dedicated to support letters of credit and 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 cash and cash equivalents balance at ~~March 31~~,June 30, 2008 was approximately ~~$502.6~~$273.6 million and the amount available on the Operating Partnership’s revolving credit facility was $1.4 billion (net of ~~$77.5~~$74.0 million which was restricted/dedicated to support letters of credit and not available for borrowing). The significant increase in the Operating Partnership’s cash and cash equivalents balance since December 31, 2007 is a direct result of its decision to pre-fund its 2008 debt maturities with the closing of a $500.0 million secured mortgage pool in March 2008. See ~~Note~~Notes 8 and 10 in the Notes to Consolidated Financial Statements for further discussion.
During the ~~quarter~~six months ended ~~March~~ ~~31,~~June 30, 2008, the Operating Partnership generated proceeds from various transactions, which included the following:

·~~Disposed of 17 properties and various individual condominium units, receiving net proceeds of approximately $284.3 million;~~32
·Obtained $563.1 million in new mortgage financing and terminated three forward starting swaps designated to hedge the first $150.0 million of one of the loan issuances, making payments of $13.2 million; and
·~~Issued approximately 0.2 million OP Units and received net proceeds of $5.8 million.~~
—
Disposed of 23 properties and various individual condominium units, receiving net proceeds of approximately $494.2 million;
—
Obtained $619.7 million in new mortgage financing and terminated three forward starting swaps designated to hedge the first $150.0 million of one of the loan issuances, making payments of $13.2 million; and

The Operating Partnership 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, generally through its working capital, net cash provided by operating activities and borrowings under its revolving credit facility. The Operating Partnership considers its cash provided by operating activities to be adequate to meet operating requirements and payments of distributions. The Operating Partnership 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 unsecured notes and equity securities, including

3236

additional OP Units, and proceeds received from the disposition of certain properties as well as joint ventures. In addition, the Operating Partnership 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 must maintain in order to comply with covenants under its unsecured notes and line of credit. Of the ~~$18.3~~$18.7 billion in investment in real estate on the Operating Partnership’s balance sheet at ~~March 31,~~June 30, 2008, ~~$11.3~~$11.6 billion or ~~61.5%~~62.2%, was unencumbered.
As of ~~May 1,~~July 31, 2008, the Operating Partnership’s senior debt credit ratings from Standard & Poors (“S&P”), Moody’s and Fitch are BBB+, Baa1 and A-, respectively. As of ~~May 1,~~July 31, 2008, EQR’s preferred equity ratings from S&P, Moody’s and Fitch are ~~BBB,~~BBB-, Baa2 and BBB+, respectively.
The Operating Partnership has a long-term revolving credit facility with potential borrowings of up to $1.5 billion which matures in February 2012. This facility may, among other potential uses, be used to fund property acquisitions, costs for certain properties under development and short term liquidity requirements. As of ~~May 1,~~July 31, 2008, no amounts were outstanding under this facility.
See Note 16 in the Notes to Consolidated Financial Statements for discussion of the events which occurred subsequent to ~~March 31,~~June 30, 2008.
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 unit). These include:                  ~~Replacements~~ ~~(inside the 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.~~
o
flooring such as carpets, hardwood, vinyl, linoleum or tile;
o
appliances;
o
mechanical equipment such as individual furnace/air units, hot water heaters, etc;
o
furniture and fixtures such as kitchen/bath cabinets, light fixtures, ceiling fans, sinks, tubs, toilets, mirrors, countertops, etc; and
o
blinds/shades.
All replacements are depreciated over a five-year estimated useful life. We expense as incurred all make-ready maintenance and turnover costs such as cleaning, interior painting of individual units and the repair of any replacement item noted above.

·
—
Building improvements (outside the unit). These include:                  ~~Building improvements (~~~~outside the 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~~
·                  ~~vehicles and office and maintenance equipment.~~
o
roof replacement and major repairs;
o
paving or major resurfacing of parking lots, curbs and sidewalks;
o
amenities and common areas such as pools, exterior sports and playground equipment, lobbies, clubhouses, laundry rooms, alarm and security systems and offices;
o
major building mechanical equipment systems;
o
interior and exterior structural repair and exterior painting and siding;
o
major landscaping and grounds improvement; and
o
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, 2008, our actual improvements to real estate totaled approximately ~~$40.7~~$86.4 million. This includes the following (amounts in thousands except for unit and per unit amounts):

~~(3)  New Acquisition Properties – Wholly Owned Properties acquired during 2006, 2007 and 2008.~~

(2)
Established Properties – Wholly Owned Properties acquired prior to January 1, 2006.
(3)
New Acquisition Properties – Wholly Owned Properties acquired during 2006, 2007 and 2008. Per unit amounts are based on a weighted average of 17,766 units.
(4)
Other – Includes properties either partially owned or sold during the period, commercial space, corporate housing and condominium conversions. Also includes $16.4 million included in replacements spent on various assets related to major renovations and repositioning of these assets.
For 2008, the Operating Partnership estimates an annual stabilized run rate of approximately $1,100 per unit of capital expenditures for its established properties. The above assumption is based on current expectations and is forward-looking.
During the ~~quarter~~six months ended ~~March~~ ~~31,~~June 30, 2008, the Operating Partnership’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 property management offices and its corporate offices, were approximately ~~$1.0~~$1.4 million. The Operating Partnership expects to fund approximately ~~$2.7~~$2.4 million in ~~total~~ additions to non-real estate property for the remainder of 2008. 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.
Derivative Instruments
In the normal course of business, the Operating Partnership is exposed to the effect of interest rate changes. The Operating Partnership ~~limits~~seeks to limit these risks by following established risk management policies and procedures including the use of derivatives to hedge interest rate risk on debt instruments.
The Operating Partnership 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 has not sustained a material loss from those instruments nor does it anticipate any material adverse effect on its net income or financial position in the future from the use of derivatives.
See Note 11 in the Notes to Consolidated Financial Statements for additional discussion of derivative instruments at ~~March~~ 31,June 30, 2008.

3438

Other
Total distributions paid in ~~April~~July 2008 amounted to ~~$141.8~~$141.9 million (excluding distributions on Partially Owned Properties), which included certain distributions declared during the ~~first~~second quarter ended ~~March~~ ~~31,~~June 30, 2008.
Off-Balance Sheet Arrangements and Contractual Obligations
The Operating Partnership has co-invested in various properties that are unconsolidated and accounted for under the equity method of accounting. Management does not believe these investments have a materially different impact upon the Operating Partnership’s liquidity, cash flows, capital resources, credit or market risk than its property management and ownership activities. During 2000 and 2001, the Operating Partnership entered into institutional ventures with an unaffiliated partner. At the respective closing dates, the Operating Partnership sold and/or contributed 45 properties containing 10,846 units to these ventures and retained a 25% ownership interest in the ventures. The Operating Partnership’s joint venture partner contributed cash equal to 75% of the agreed-upon equity value of the properties comprising the ventures, which was then distributed to the Operating Partnership. The Operating Partnership’s strategy with respect to these ventures was to reduce its concentration of properties in a variety of markets. The Operating Partnership sold one property consisting of 400 units during the year ended December 31, 2007.
As of ~~March~~ ~~31,~~June 30, 2008, the Operating Partnership has 1311 projects totaling ~~4,484~~3,733 units in various stages of development with estimated completion dates ranging through June 30, 2011. The development agreements currently in place are discussed in detail in Note 14 of the Operating Partnership’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 investments in partially owned entities.
The Operating Partnership’s contractual obligations for the next five years and thereafter have not changed materially from the amounts and disclosures included in its annual report 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 Operating Partnership has identified six 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 six critical accounting policies are:
Impairment of Long-Lived Assets, Including Goodwill
The Operating Partnership periodically evaluates its long-lived assets, including its investments in real estate and goodwill, for indicators of permanent impairment. The judgments regarding the existence of impairment indicators are based on factors such as operational performance, market conditions, expected holding period of each asset and legal and environmental concerns. Future events could occur which would cause the Operating Partnership to conclude that impairment indicators exist and an impairment loss is warranted.

3539

Depreciation of Investment in Real Estate
The Operating Partnership 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 estimated useful life, all of which are judgmental determinations.
Cost Capitalization
See theCapitalization of Fixed Assets and Improvements to Real Estate section for discussion of the policy with respect to capitalization vs. expensing of fixed asset/repair and maintenance costs. In addition, the Operating Partnership capitalizes the payroll and associated costs of employees directly responsible for and who spend all of 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.
The Operating Partnership follows the guidance in SFAS No. 67,Accounting for Costs and Initial Rental Operations of Real Estate Projects, for all development projects and uses its professional judgment in determining whether such costs meet the criteria for capitalization or must be expensed as incurred. The Operating Partnership capitalizes interest, real estate taxes and insurance and payroll and associated costs for those individuals directly responsible for and who spend all of 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 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 renovation at selected properties when additional incremental employees are hired.
Fair Value of Financial Instruments, Including Derivative Instruments
The Operating Partnership follows the guidance under SFAS No. 157 when valuing its financial instruments. The valuation of financial instruments under SFAS No. 107 and SFAS No. 133, as amended, requires the Operating Partnership to make estimates and judgments that affect the fair value of the instruments. The Operating Partnership, 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 bases its estimates on current instruments with similar terms and maturities or on other factors relevant to the financial statements.
Revenue Recognition
Rental income attributable to residential leases is recorded on a straight-line basis, which is not materially different than if it were recorded when due from residents and is recognized monthly as it ~~is earned, which is not materially different than on a straight-line basis.~~was earned. Leases entered into between a resident and a property for the rental of an apartment unit are generally year-to-year, renewable upon consent of both parties on an annual or monthly basis. Fee and asset management revenue and interest income are recorded on an accrual basis.
Share-Based Compensation
The Company accounts for its share-based compensation in accordance with SFAS No. 123(R),Share-Based Payment, effective January 1, 2006, which results in compensation expense being recorded based on the fair value of the share compensation granted.
36

Any EQR Common Shares issued pursuant to EQR’s incentive equity compensation and employee share purchase plans will result in the Operating Partnership issuing OP Units to EQR on a one-for-one basis, with the Operating Partnership receiving the net cash proceeds of such issuances.

40
The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. This model is only one method of valuing options and the Company’s use of this model should not be interpreted as an endorsement of its accuracy. Because the Company’s share options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its share options and the actual value of the options may be significantly different.
Funds From Operations
For the ~~quarter~~six months ended ~~March 31,~~June 30, 2008, Funds From Operations (“FFO”) available to OP Units ~~decreased~~increased by ~~$2.5~~$0.2 million or ~~1.4%~~0.1%, as compared to the six months ended June 30, 2007.
For the quarter ended June 30, 2008, FFO available to OP Units increased by $2.7 million, or 1.5%, as compared to the quarter ended ~~March 31,~~June 30, 2007.
The following is a reconciliation of net income to FFO available to OP Units for the six months and quarters ended ~~March 31,~~June 30, 2008 and 2007:

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 commences the conversion of units to condominiums, it simultaneously discontinues depreciation of such property. FFO available to OP Units is calculated on a basis consistent with net income available to OP Units and reflects adjustments to net income for preferred distributions and premiums on redemption of preference units/interests in accordance with accounting principles generally accepted in the United States.

The Operating Partnership believes that FFO and FFO available to OP 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 OP Units can help compare the operating performance of a company’s real estate between periods or as compared to different companies. FFO and FFO available to OP Units do not represent net income, net income available to OP Units or net cash flows from operating activities in accordance with GAAP. Therefore, FFO and FFO available to OP Units should not be exclusively considered as alternatives to net income,The Operating Partnership believes that FFO and FFO available to OP 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 OP Units can help compare the operating performance of a company’s real estate between periods or as compared to different companies.

Therefore, FFO and FFO available to OP Units should not be exclusively considered as alternatives to net income,~~ net income available to OP Units or net cash flows from operating activities as determined by GAAP or as measures of liquidity. The Operating Partnership’s calculation of FFO and FFO available to OP 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.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
The Operating Partnership’s market risk has not changed materially from the amounts and information reported in Item 7A,Quantitative and Qualitative Disclosures About Market Risk, to the Operating Partnership’s Form 10-K for the year ended December 31, 2007. See also Note 11 in the Notes to Consolidated Financial Statements for additional discussion of derivative instruments.
Item 4. Controls and Procedures
(a)Evaluation of Disclosure Controls and Procedures:
Effective as of ~~March 31,~~June 30, 2008, the Operating Partnership carried out an evaluation, under the supervision and with the participation of the Operating Partnership’s management, including the Chief Executive Officer and Chief Financial Officer of EQR, of the effectiveness of the Operating Partnership’s disclosure controls and procedures pursuant to Exchange Act Rules 13a-15 and 15d-15. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures are effective to ensure that information required to be disclosed by the Operating Partnership in its Exchange Act filings is recorded, processed, summarized and reported within the periods specified in the SEC’s rules and forms.
(b) Changes in Internal Control over Financial Reporting:
During the first quarter of 2008, the Operating Partnership completed the implementation of a new general ledger and accounts payable system designed to integrate its financial and operating platforms. The Operating Partnership believes this implementation constitutes an improvement to its internal control over financial reporting.
~~Except for the preceding change, there~~There were no changes to the internal control over financial reporting of the Operating Partnership identified in connection with the Operating Partnership’s evaluation referred to above that occurred during the ~~first~~second quarter of 2008 that have materially affected, or are reasonably likely to materially affect, the Operating Partnership’s internal control over financial reporting.

Item 1.  Legal Proceedings
The Operating Partnership 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 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 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. Accordingly, the Operating Partnership is defending the suit vigorously. Due to the pendency of the Operating Partnership’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 and as a result, no amounts have been accrued at March 31, 2008. While no assurances can be given, the Operating Partnership does not believe that the suit, if adversely determined, will have a material adverse effect on the Operating Partnership.
The Operating Partnership does not believe that there ishave been any ~~other litigation pending or threatened against it that, individually or~~material developments in the ~~aggregate, reasonably may be expected to have a material adverse effect on~~legal proceedings that were discussed in Part I, Item 3 of the Operating ~~Partnership.~~Partnership’s Form 10-K for the year ended December 31, 2007.
Item 1A.  Risk Factors
There have been no material changes related to the risk factors that were discussed in Part I, Item 1A of the Operating Partnership’s Form 10-K for the year ended December 31, 2007.
