1. Description of Business

Business. Formed on May 25, 1993, Camden Property Trust, a Texas real estate investment trust (“REIT”), is engaged in the ownership, management, development, acquisition, and construction of multifamily apartment communities. Our multifamily apartment communities are referred to as “communities,” “multifamily communities,” “properties,” or “multifamily properties” in the following discussion. As of March 31, 2011, we owned interests in, operated, or were developing 190 multifamily properties comprising 64,509 apartment homes across the United States. Of the 190 properties, three properties were under development, and when completed will consist of a total of 711 apartment homes. In addition, we own land parcels we may develop into multifamily apartment communities.

2. Summary of Significant Accounting Policies

Principles of Consolidation. Our condensed consolidated financial statements include our accounts and the accounts of other subsidiaries and joint ventures (including partnerships and limited liability companies) over which we have control. All intercompany transactions, balances, and profits have been eliminated in consolidation. Investments acquired or created are continuously evaluated based on the accounting guidance relating to variable interest entities (“VIEs”), which requires the consolidation of VIEs in which we are considered to be the primary beneficiary. If the investment is determined not to be a VIE, then the investment is evaluated for consolidation (primarily using a voting interest model) under the remaining consolidation guidance relating to real estate entities. If we are the general partner of a limited partnership, or manager of a limited liability company, we also consider the consolidation guidance relating to the rights of limited partners (non-managing members) to assess whether any rights held by the limited partners overcome the presumption of control by us.

Interim Financial Reporting. We have prepared these financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, these statements do not include all information and footnote disclosures required for annual financial statements. While we believe the disclosures presented are adequate for interim reporting, these interim financial statements should be read in conjunction with the audited financial statements and notes included in our 2010 Annual Report on Form 10-K. In the opinion of management, all adjustments and eliminations, consisting of normal recurring adjustments, necessary for a fair representation of our financial statements for the interim period reported have been included. Operating results for the three months ended March 31, 2011 are not necessarily indicative of the results which may be expected for the full year.

Asset Impairment. Long-lived assets are reviewed for impairment annually or whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Impairment exists if estimated future undiscounted cash flows associated with long-lived assets are not sufficient to recover the carrying value of such assets. We consider projected future discounted and undiscounted cash flows, trends, strategic decisions regarding future development plans, and other factors in our assessment of whether impairment conditions exist. When impairment exists, the long-lived asset is adjusted to its fair value. While we believe our estimates of future cash flows are reasonable, different assumptions regarding a number of factors, including market rents, economic conditions, and occupancies, could significantly affect these estimates. In estimating fair value, management uses appraisals, management estimates, and discounted cash flow calculations which maximize inputs from a marketplace participant’s perspective. In addition, we evaluate our equity investments in joint ventures and if we believe there is an other than temporary decline in market value of our investment, we will record an impairment charge.

The value of our properties under development depends on market conditions, including estimates of the project start date as well as estimates of demand for multifamily communities. We have reviewed market trends and other marketplace information and have incorporated this information as well as our current outlook into the assumptions we use in our impairment analyses. Due to, among other factors, the judgment and assumptions applied in the impairment analyses and the fact limited market information regarding the value of comparable land exists at this time, it is possible actual results could differ substantially from those estimated.

8

We believe the carrying value of our operating real estate assets, properties under development, and land is currently recoverable. However, if market conditions deteriorate or if changes in our development strategy significantly affect any key assumptions used in our fair value calculations, we may need to take material charges in future periods for impairments related to existing assets. Any such material non-cash charges would have an adverse effect on our consolidated financial position and results of operations.

Cash and Cash Equivalents. All cash and investments in money market accounts and other highly liquid securities with a maturity of three months or less at the date of purchase are considered to be cash and cash equivalents. We maintain the majority of our cash and cash equivalents at major financial institutions in the United States and deposits with these financial institutions may exceed the amount of insurance provided on such deposits; however, we regularly monitor the financial stability of these financial institutions and believe we are not currently exposed to any significant default risk with respect to these deposits.

Cost Capitalization. Real estate assets are carried at cost plus capitalized carrying charges. Carrying charges are primarily interest and real estate taxes which are capitalized as part of properties under development. Capitalized interest is generally based on the weighted average interest rate of our unsecured debt. Transaction costs associated with the acquisition of real estate assets are expensed. Expenditures directly related to the development and improvement of real estate assets are capitalized at cost as land and buildings and improvements. Indirect development costs, including salaries and benefits and other related costs directly attributable to the development of properties, are also capitalized. All construction and carrying costs are capitalized and reported in the balance sheet as properties under development until the apartment homes are substantially completed. Upon substantial completion of the apartment homes, the total cost for the apartment homes and the associated land is transferred to buildings and improvements and land, respectively.

As discussed above, carrying charges are principally interest and real estate taxes capitalized as part of properties under development and buildings and improvements. Capitalized interest was approximately $1.8 million for the three months ended March 31, 2011, and approximately $1.3 million for the three months ended March 31, 2010. Capitalized real estate taxes were approximately $0.4 million for the three months ended March 31, 2011, and approximately $0.3 million for the three months ended March 31, 2010.

Where possible, we stage our construction to allow leasing and occupancy during the construction period, which we believe minimizes the duration of the lease-up period following completion of construction. Our accounting policy related to properties in the development and leasing phase is to expense all operating expenses associated with completed apartment homes. We capitalize renovation and improvement costs we believe extend the economic lives of depreciable property. Capital expenditures subsequent to initial construction are capitalized and depreciated over their estimated useful lives.

Depreciation and amortization is computed over the expected useful lives of depreciable property on a straight-line basis with lives generally as follows:

	Estimated
	Useful Life
Buildings and improvements	5-35 years
Furniture, fixtures, equipment, and other	3-20 years
Intangible assets (in-place leases and above and below market leases)	underlying lease term

Derivative Financial Instruments. Derivative financial instruments are recorded in the condensed consolidated balance sheets at fair value and we do not apply master netting for financial reporting purposes. Accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows or other types of forecasted transactions are cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes attributable to the earnings effect of the hedged transactions. We may enter into derivative contracts which are intended to economically hedge certain of our risks, even though hedge accounting does not apply or we elect not to apply hedge accounting.

9

Income Recognition. Our rental and other property revenue is recorded when due from residents and is recognized monthly as it is earned. Other property revenue consists primarily of utility rebillings and administrative, application, and other transactional fees charged to our residents. Our apartment homes are rented to residents on lease terms generally ranging from six to fifteen months, with monthly payments due in advance. All other sources of income, including from interest and fee and asset management income, are recognized as earned. Nine of our properties are subject to rent control. Operations of multifamily properties acquired are recorded from the date of acquisition in accordance with the acquisition method of accounting. In management’s opinion, due to the number of residents, the types and diversity of submarkets in which our properties operate, and the collection terms, there is no significant concentration of credit risk.

Reportable Segments. Our multifamily communities are geographically diversified throughout the United States, and management evaluates operating performance on an individual property level. As each of our apartment communities has similar economic characteristics, residents, and products and services, our apartment communities have been aggregated into one reportable segment. Our multifamily communities generate rental revenue and other income through the leasing of apartment homes, which comprised approximately 96.1% and 96.8% of our total property revenues and total non-property income, excluding income on deferred compensation plans, for the three months ended March 31, 2011 and 2010, respectively.

Use of Estimates. In the application of GAAP, management is required to make estimates and assumptions which affect the reported amounts of assets and liabilities at the date of the financial statements, results of operations during the reporting periods, and related disclosures. Our more significant estimates include estimates supporting our impairment analysis related to the carrying values of our real estate assets, estimates related to the valuation of our investments in joint ventures and estimates and assumptions used to determine the entity with the power to direct activities that most significantly impacts economic performance of potential variable interest entities. These estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances. Future events rarely develop exactly as forecasted, and the best estimates routinely require adjustment.

3. Share Data

Basic earnings per share are computed using net income attributable to common shareholders and the weighted average number of common shares outstanding. Diluted earnings per share reflect common shares issuable from the assumed conversion of common share options and share awards granted and units convertible into common shares. Only those items having a dilutive impact on our basic earnings per share are included in diluted earnings per share. Our unvested share-based awards are considered participating securities and are reflected in the calculation of basic and diluted earnings per share using the two-class method. The number of common share equivalent securities excluded from the diluted earnings per share calculation for the three months ended March 31, 2011, and 2010 was approximately 4.1 million and 5.1 million, respectively. These securities, which include common share options and share awards granted and units convertible into common shares, were excluded from the diluted earnings per share calculation as they are anti-dilutive.

4. Common Shares

We currently have an automatic shelf registration statement on file with the SEC which allows us to offer, from time to time, an unlimited amount of common shares, preferred shares, debt securities, or warrants. Our declaration of trust provides we may issue up to 110.0 million shares of beneficial interest, consisting of 100.0 million common shares and 10.0 million preferred shares. As of March 31, 2011, we had approximately 70.0 million common shares outstanding, net of treasury shares and shares held in our deferred compensation plans, and no preferred shares outstanding.

In March 2010, we originated an at-the-market (“ATM”) share offering program through which we can sell common shares having an aggregate offering price of up to $250 million from time to time into the existing trading market at current market prices as well as through negotiated transactions. We may, but shall have no obligation to, sell common shares through the ATM share offering program in amounts and at times as we determine. Actual sales from time to time may depend on a variety of factors including, among others, market conditions, the trading price of our common shares, and determinations of the appropriate sources of funding for us. During the three months ended March 31, 2011, we issued approximately 0.1 million common shares at an average price of $54.06 per share for total net consideration of approximately $3.8 million. In April 2011, we issued an additional 0.2 million common shares at an average price of $56.50 per share for total net considerations of approximately $10.1 million. Cumulative to date, we have issued approximately 5.1 million common shares at an average price of $48.73 for total net consideration of approximately $245.3 million. As of the date of this filing, we had common shares having an aggregate offering price of up to $0.5 million remaining available for sale under the ATM program.

5. Investments in Joint Ventures

As of March 31, 2011, our equity investments in unconsolidated joint ventures, which we account for utilizing the equity method of accounting, consisted of 17 joint ventures, with our ownership percentages ranging from 15% to 50%. We currently provide property management services to each of these joint ventures which own operating properties and may provide construction and development services to the joint ventures which own properties under development. The following table summarizes aggregate balance sheet and statement of income data for the unconsolidated joint ventures as of and for the periods presented:

	March 31,		December 31,
(in millions)	2011(1)		2010
Total assets	$	959.2	$	935.3
Total third-party debt		811.3		810.1
Total equity		132.8		105.3

	March 31,			March 31,
	2011			2010
Total revenues	$	33.0		$	33.7
Net loss		(2.6	)		(5.0	)
Equity in income (loss)(2)		0.4			(0.1	)

(1)	During the three months ended March 31, 2011, we sold our ownership interests in three joint ventures and one of our discretionary funds (the “Funds”) acquired three multifamily properties as further discussed below.
(2)	Equity in income (loss) excludes our ownership interest of fee income from various property management services with our joint ventures.

The joint ventures in which we have an interest have been funded in part with secured, third-party debt. As of March 31, 2011, we have no outstanding guarantees related to loans utilized for construction and development activities for our unconsolidated joint ventures.

We may earn fees for property management, construction, development, and other services related to joint ventures in which we own an interest. Fees earned for these services, excluding third-party construction fees, amounted to approximately $1.5 million and $1.6 million for the three months ended March 31, 2011 and 2010, respectively. We eliminate fee income from property management services provided to these joint ventures to the extent of our ownership.

12

During March 2011, we sold our ownership interests in three unconsolidated joint venture communities for total proceeds of approximately $19.3 million and recognized a gain of approximately $1.1 million.

During the three months ended March 31, 2011, one of our Funds, in which we have a 20% interest, acquired three multifamily properties for an aggregate net purchase price of approximately $122.6 million. The acquisitions were comprised of 352 units located in Houston, Texas, 355 units located in Dallas, Texas and 234 units located in Atlanta, Georgia.

In April 2011, we sold one of our development properties in Washington, D.C. to one of the Funds for approximately $9.4 million and we were reimbursed for previously written-off development costs, resulting in a gain of approximately $4.7 million.

We have a $500 million unsecured credit facility, with the option to increase this credit facility to $600 million at our election, which matures in August 2012 and may be extended at our option to August 2013. Interest rate spreads float on a margin based on LIBOR and are subject to change as our credit ratings change. Advances under the line of credit may be priced at the scheduled rates, or we may enter into bid rate loans with participating banks at rates below the scheduled rates. These bid rate loans have terms of 180 days or less and may not exceed the lesser of $250 million or the remaining amount available under the line of credit. The line of credit is subject to customary financial covenants and limitations, all of which we are in compliance.

Our line of credit provides us with the ability to issue up to $100 million in letters of credit. While our issuance of letters of credit does not increase our borrowings outstanding under our line of credit, it does reduce the amount available. At March 31, 2011, we had outstanding letters of credit totaling approximately $10.2 million, leaving approximately $489.8 million available under our unsecured line of credit.

At March 31, 2011 and 2010, the weighted average interest rate on our floating rate debt, which includes our unsecured line of credit, was 1.3% and 1.2%, respectively.

13

We repaid the remaining principal amount of our 7.69% senior unsecured notes, which matured on February 15, 2011, for a total of approximately $88.0 million.

Our indebtedness, including our unsecured line of credit, had a weighted average maturity of 5.5 years at March 31, 2011. Scheduled repayments on outstanding debt assuming all contractual extensions, including our line of credit and scheduled principal amortizations, and the weighted average interest rate on maturing debt at March 31, 2011 are as follows:

			Weighted

7. Derivative Instruments and Hedging Activities

Risk Management Objective of Using Derivatives. We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of our debt funding and the use of derivative financial instruments. Specifically, we may enter into derivative financial instruments to manage exposures arising from business activities resulting in differences in the amount, timing, and duration of our known or expected cash payments principally related to our borrowings.

Cash Flow Hedges of Interest Rate Risk. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish these objectives, we primarily use interest rate swaps and caps as part of our interest rate risk management strategy. Interest rate swaps involve the receipt of variable rate amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate caps involve the receipt of variable rate amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an upfront premium.

Designated Hedges. The effective portion of changes in the fair value of derivatives designated and qualifying as cash flow hedges is recorded in accumulated other comprehensive income or loss and is subsequently reclassified into earnings in the period the hedged forecasted transaction affects earnings. Over the next twelve months, we estimate $22.3 million will be reclassified to interest expense. During the three months ending March 31, 2011 and 2010, such derivatives were used to hedge the variable cash flows associated with existing variable rate debt. The ineffective portion of the change in fair value of the derivatives, if any, is recognized directly in earnings. No portion was ineffective during the three months ended March 31, 2011 and 2010.

As of March 31, 2011, we had the following outstanding interest rate derivatives designated as cash flow hedges of interest rate risk:

Interest Rate Derivative	Number of Instruments		Notional Amount
Interest Rate Swaps		2	$516.6 million

Non-designated Hedges. Derivatives not designated as hedges are not speculative and are used to manage our exposure to interest rate movements and other identified risks. Non-designated hedges are either specifically non-designated by management or do not meet strict hedge accounting requirements. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings in other income or other expense.

14

As of March 31, 2011, we had the following outstanding interest rate derivative which was not designated as a hedge of interest rate risk:

Interest Rate Derivative	Number of Instruments		Notional Amount
Interest Rate Cap		1	$175.0 million

Credit-risk-related Contingent Features. Derivative financial investments expose us to credit risk in the event of non-performance by the counterparties under the terms of the interest rate hedge agreements. We believe we minimize our credit risk on these transactions by transacting with major creditworthy financial institutions. As part of our on-going control procedures, we monitor the credit ratings of counterparties and our exposure to any single entity, which we believe minimizes credit risk concentration.

Our agreements with each of our derivative counterparties contain provisions which provide the counterparty the right to declare a default on our derivative obligations if we are in default on any of our indebtedness, subject to certain thresholds. For all instances, these provisions include a default even if there is no acceleration of the indebtedness. Our agreements with each of our derivative counterparties also provide if we consolidate with, merge with or into, or transfer all or substantially all our assets to another entity and the creditworthiness of the resulting, surviving, or transferee entity is materially weaker than ours, the counterparty has the right to terminate the derivative obligations.

15

At March 31, 2011, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk (the “termination value”), related to these agreements was approximately $33.5 million. As of March 31, 2011, we had not posted any collateral related to these agreements. If we were in breach of any of these provisions at March 31, 2011, or terminated these agreements, we would have been required to settle our obligations at their aggregate termination value of approximately $33.5 million.

8. Share-based Compensation

Options. During the three months ended March 31, 2011, 0.2 million options were exercised at prices ranging from $30.06 to $48.02 per option. The total intrinsic value of options exercised during the three months ended March 31, 2011 was approximately $3.7 million. As of March 31, 2011, there was approximately $2.0 million of total unrecognized compensation cost related to unvested options, which is expected to be amortized over the next three years. At March 31, 2011, outstanding options and exercisable options had a weighted average remaining life of approximately 5.0 years and 3.9 years respectively.

The following table summarizes outstanding share options and exercisable options at March 31, 2011:

	Outstanding Options (1)				Exercisable Options (1)
			Weighted Average				Weighted Average
Range of Exercise Prices	Number		Price		Number		Price
$30.06-$41.91		560,668	$	33.10		266,963	$	36.45
$42.90-$44.00		350,063		43.52		312,800		43.47
$45.53-$73.32		680,681		49.68		527,530		50.16
Total options		1,591,412	$	42.48		1,107,293	$	44.96

(1) The aggregate intrinsic values of outstanding options and exercisable options at March 31, 2011 were $23.5 million and $13.8 million, respectively. The aggregate intrinsic values were calculated as the excess, if any, between our closing share price of $56.82 per share on March 31, 2011 and the strike price of the underlying award.

Valuation Assumptions. Options generally have a vesting period of three to five years. We estimate the fair values of each option award on the date of grant using the Black-Scholes option pricing model. No new options have been granted in 2011.

Share Awards and Vesting. Share awards generally have a vesting period of five years. The compensation cost for share awards is based on the market value of the shares on the date of grant and is amortized over the vesting period. To estimate forfeitures, we use actual forfeiture history. At March 31, 2011, the unamortized value of previously issued unvested share awards was approximately $36.7 million which is expected to be amortized over the next five years. The total fair value of shares vested during the three months ended March 31, 2011 and 2010 was approximately $10.6 million and $9.6 million, respectively, and approximately 2.6 million vested share awards were outstanding at March 31, 2011 with a weighted average issuance price of $39.41 per share.

Total compensation cost for option and share awards charged against income was approximately $2.9 million and $3.1 million for the three months ended March 31, 2011 and 2010, respectively. Total capitalized compensation cost for option and share awards was approximately $0.3 million and $0.5 million for the three months ended March 31, 2011 and 2010, respectively.

10. Commitments and Contingencies

Construction Contracts. As of March 31, 2011, we have construction commitments of approximately $56.6 million of additional expenditures on our construction projects currently under development. We expect to fund these amounts through available cash balances, cash flows generated from operations, draws on our unsecured credit facility, proceeds from property dispositions, and the use of debt and equity offerings under our automatic shelf registration statement.

Litigation. One of our wholly-owned subsidiaries previously acted as a general contractor for the construction of three apartment projects in Florida which were subsequently sold and converted to condominium units by unrelated third-parties. Each condominium association of those projects has asserted claims against our subsidiary alleging, in general, defective construction as a result of alleged negligence and an alleged failure to comply with building codes. Two of the associations have filed suit against our subsidiary and other unrelated third parties in Florida claiming damages, in unspecified amounts, for the costs of repair arising out of the alleged defective construction as well as the recovery of incidental and consequential damages resulting from such alleged negligence. Each of the suits is in a very early stage, and no significant discovery has been conducted. While we have denied liability to the associations, it is not possible to determine the potential outcome nor is it possible to estimate the amount of loss, if any, that would be associated with any potential adverse decision.

17

We are also subject to various legal proceedings and claims which arise in the ordinary course of business. Matters which arise out of allegations of bodily injury, property damage, and employment practices are generally covered by insurance. While the resolution of these legal proceedings and claims cannot be predicted with certainty, management believes the final outcome of such matters will not have a material adverse effect on our condensed consolidated financial statements.

Other Contingencies. In the ordinary course of our business, we issue letters of intent indicating a willingness to negotiate for acquisitions, dispositions, or joint ventures and also enter into arrangements contemplating various transactions. Such letters of intent and other arrangements are non-binding as to either party unless and until a definitive contract is entered into by the parties. Even if definitive contracts relating to the purchase or sale of real property are entered into, these contracts generally provide the purchaser with time to evaluate the property and conduct due diligence, during which periods the purchaser will have the ability to terminate the contracts without penalty or forfeiture of any deposit or earnest money. There can be no assurance definitive contracts will be entered into with respect to any matter covered by letters of intent or we will consummate any transaction contemplated by any definitive contract. Furthermore, due diligence periods for real property are frequently extended as needed. An acquisition or sale of real property becomes probable at the time the due diligence period expires and the definitive contract has not been terminated. We are then at risk under a real property acquisition contract, but generally only to the extent of any earnest money deposits associated with the contract, and are obligated to sell under a real property sales contract.

Lease Commitments. At March 31, 2011, we had long-term leases covering certain land, office facilities, and equipment. Rental expense totaled approximately $0.7 million and $0.8 million for the three months ended March 31, 2011 and 2010, respectively. Minimum annual rental commitments for the remainder of 2011 are $1.8 million, and for the years ending December 31, 2012 through 2015 are approximately $2.1 million, $2.0 million, $1.9 million, and $1.1 million, respectively, and $0.6 million in the aggregate thereafter.

Investments in Joint Ventures. We have entered into, and may continue in the future to enter into, joint ventures or partnerships (including limited liability companies) through which we own an indirect economic interest in less than 100% of the community or communities owned directly by the joint venture or partnership. Our decision whether to hold the entire interest in an apartment community ourselves, or to have an indirect interest in the community through a joint venture or partnership, is based on a variety of factors and considerations, including: (i) our projection, in some circumstances, that we will achieve higher returns on our invested capital or reduce our risk if a joint venture or partnership vehicle is used; (ii) our desire to diversify our portfolio of communities by market; (iii) our desire at times to preserve our capital resources to maintain liquidity or balance sheet strength; and (iv) the economic and tax terms required by a seller of land or of a community, who may prefer or who may require less payment if the land or community is contributed to a joint venture or partnership. Investments in joint ventures or partnerships are not limited to a specified percentage of our assets. Each joint venture or partnership agreement is individually negotiated, and our ability to operate and/or dispose of a community in our sole discretion is limited to varying degrees in our existing joint venture agreements and may be limited to varying degrees depending on the terms of future joint venture agreements.

11. Income Taxes

We have maintained and intend to maintain our election as a REIT under the Internal Revenue Code of 1986, as amended. In order for us to continue to qualify as a REIT, we must meet a number of organizational and operational requirements, including a requirement to distribute annual dividends to our shareholders equal to a minimum of 90% of our REIT taxable income, computed without regard to the dividends paid deduction and our net capital gains. As a REIT, we generally will not be subject to federal income tax on our taxable income at the corporate level to the extent such income is distributed to our shareholders annually. If our taxable income exceeds our dividends in a tax year, REIT tax rules allow us to designate dividends from the subsequent tax year in order to avoid current taxation on undistributed income. If we fail to qualify as a REIT in any taxable year, we will be subject to federal and state income taxes at regular corporate rates, including any applicable alternative minimum tax. In addition, we may not be able to requalify as a REIT for the four subsequent taxable years. Historically, we have incurred only state and local income, franchise, and excise taxes. Taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to applicable federal, state, and local income taxes. Our operating partnerships are flow-through entities and are not subject to federal income taxes at the entity level.

18

We have provided for income, franchise, and state income taxes in the condensed consolidated statements of income and comprehensive income for the three months ended March 31, 2011 and 2010. The income taxes during the three months ended March 31, 2011 are primarily related to approximately $1.0 million associated with the gain recognized on the sale of our available-for-sale investment discussed in Footnote 12, “Fair Value Disclosures,” below. Other tax expense is related to entity level taxes on certain ventures, state taxes, and federal taxes on certain of our taxable REIT subsidiaries. We have no significant temporary differences or tax credits associated with our taxable REIT subsidiaries.

We believe we have no uncertain tax positions or unrecognized tax benefits requiring disclosure as of and for the three months ended March 31, 2011.

12. Fair Value Disclosures

For financial assets and liabilities fair valued on a recurring basis, fair value is the price we would receive to sell an asset, or pay to transfer a liability, in an orderly transaction with a market participant at the measurement date. In the absence of such data, fair value is estimated using internal information consistent with what market participants would use in a hypothetical transaction which occurs at the transaction date.

Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions; preference is given to observable inputs. These two types of inputs create the following fair value hierarchy:

• Level 1: Quoted prices for identical instruments in active markets.

• Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

• Level 3: Significant inputs to the valuation model are unobservable.

The following table presents information about our financial assets and liabilities measured at fair value as of March 31, 2011 and December 31, 2010 under the fair value hierarchy discussed above.

	March 31, 2011								December 31, 2010

Deferred Compensation Plan Investments. The estimated fair values of investment securities classified as deferred compensation plan investments are included in Level 1 and are based on quoted market prices utilizing public information for the same transactions or information provided through third-party advisors. Our deferred compensation plan investments are recorded in other assets in our condensed consolidated balance sheets. The balance at March 31, 2011 also reflects approximately $8.6 million of participant withdrawals from our deferred compensation plan investments during the quarter.

Available-for-sale Investment. During February 2011, we received proceeds from the sale of our available-for-sale investment of approximately $4.5 million, resulting in a gross realized gain of approximately $4.3 million. This available-for-sale investment was included in Level 1 in the preceding table as of December 31, 2010 and was valued using quoted market prices.

Derivative Financial Instruments. The estimated fair values of derivative financial instruments are included in Level 2 and are valued using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and volatility. The fair values of interest rate swaps and caps are estimated using the market standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments, which consider the impact of any credit enhancements to the contracts, are incorporated in the fair values to account for potential nonperformance risk, including our own nonperformance risk and the respective counterparty’s nonperformance risk. The fair value of interest rate caps are determined using the market standard methodology of discounting the future expected cash receipts which would occur if variable interest rates rise above the strike rate of the caps. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observed market interest rate curves and volatilities.

Although we have determined the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default. However, as of March 31, 2011, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

Other Fair Value Disclosures. As of March 31, 2011 and December 31, 2010, the carrying value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued expenses and other liabilities, and distributions payable approximated fair value based on the short-term nature of these instruments.

In calculating the fair value of our notes receivable and notes payable, interest rates and spreads reflect current creditworthiness and market conditions available for the issuance of notes receivable and notes payable with similar terms and remaining maturities. The following table presents the carrying and estimated fair value of our notes receivable and notes payable at March 31, 2011 and December 31, 2010:

	March 31, 2011				December 31, 2010
	Carrying		Estimated		Carrying		Estimated
(in millions)	Value		Fair Value		Value		Fair Value
Notes receivable — affiliates	$	—	$	—	$	3.2	$	3.2
Fixed rate notes payable (1)		2,244.6		2,308.6		2,333.5		2,386.0
Floating rate notes payable		229.9		212.9		230.3		212.7

(1) Includes a $500 million term loan entered into in 2007 and $16.6 million of a construction loan entered into in 2008 which are effectively fixed by the use of interest rate swaps but evaluated for estimated fair value at the floating rate.

Nonrecurring Fair Value Disclosures. Nonfinancial assets and nonfinancial liabilities measured on a nonrecurring basis primarily relate to impairment of long-lived assets or investments. There were no events during the three months ended March 31, 2011 which required fair value adjustments of our nonfinancial assets and nonfinancial liabilities.

13. Dispositions and Assets Held for Sale

Discontinued Operations and Assets Held for Sale. For the three months ended March 31, 2010, income from discontinued operations included the results of operations of two operating properties, containing 1,066 apartment homes, classified as held for sale subsequent to March 31, 2010 and sold in the fourth quarter of 2010. We had no assets classified as held for sale as of and for the three months ended March 31, 2011, and, accordingly, there was no income from discontinued operations for the three months ended March 31, 2011.

The following is a summary of income from discontinued operations for the three months ended March 31, 2010:

Executive Summary

We are primarily engaged in the ownership, management, development, acquisition and construction of multifamily apartment communities. As of March 31, 2011, we owned interests in, operated, or were developing 190 multifamily properties comprising 64,509 apartment homes across the United States as detailed in the following Property Portfolio table. In addition, we own other land parcels we may develop into multifamily apartment communities.

Despite unemployment rates remaining at high levels, our results for the most recent quarter reflect an increase in rental revenue growth for the three months ended March 31, 2011 as compared to the same period in 2010 primarily due to improvements in rental rates and average occupancy levels. We believe these improvements may be due in part to the continued decline in home ownership rates and the limited supply of new rental housing. We expect improvements in rental rates and occupancy to continue in 2011 and believe sustained revenue growth will depend on, among other things, the timing and extent of employment growth, supply levels of new multifamily housing, and the continuation of the decline in home ownership rates.

In the first quarter of 2011, one of our discretionary investment funds (the “Funds”), in which we have a 20% ownership interest, acquired three multifamily properties, totaling 941 units, for an aggregate net purchase price of approximately $122.6 million. During March 2011, we sold our ownership interests in three unconsolidated joint ventures for total proceeds of approximately $19.3 million and recognized a gain of approximately $1.1 million. Two of the joint ventures sold own multifamily properties in Houston, Texas and comprised 459 units, and one joint venture owns 6.1 pre-development acres in Houston, Texas. In April 2011, we sold one of our land development properties in Washington, D.C. to one of the Funds for approximately $9.4 million and we were reimbursed for previously written-off development costs, resulting in a gain of approximately $4.7 million. Construction commenced on this project subsequent to quarter-end and will comprise approximately 276 units.

During the second half of 2010, we began construction on two development projects, comprised of approximately 607 units with initial occupancy expected in the last half of 2011. During the three months ended March 31, 2011, we began construction on one development project comprising approximately 104 units with initial occupancy expected in early 2012. As of March 31, 2011, we have construction commitments of approximately $56.6 million of additional costs on these projects. Subsequent to quarter-end, we began construction on three development projects comprised of approximately 978 units and we expect to start several additional development projects currently held in our development pipeline later in 2011 and beyond.

Subject to market conditions, we intend to continue to look for opportunities to develop and acquire existing communities, expand our development pipeline, and complete selective dispositions. We also intend to continue to strengthen our capital and liquidity positions by continuing to focus on our core fundamentals, generating positive cash flows from operations, maintaining appropriate debt levels and leverage ratios, and controlling overhead costs. We intend to meet our liquidity requirements through available cash balances, cash flows generated from operations, draws on our unsecured credit facility, proceeds from property dispositions, and the use of debt and equity offerings under our automatic shelf registration statement.

As of March 31, 2011, we had approximately $98.8 million in cash and cash equivalents and no balances outstanding on our $500 million unsecured line of credit. We have approximately $66.5 million of remaining debt maturities in 2011, excluding scheduled principal amortizations. We believe we are well-positioned with a strong balance sheet and sufficient liquidity to cover near-term debt maturities and new development funding requirements. We will, however, continue to assess and take further actions where prudent to meet our objectives and capital requirements.

Stabilized Communities

We generally consider a property stabilized once it reaches 90% occupancy at the beginning of a period. No consolidated properties reached stabilization during the three months ended March 31, 2011.

Acquisitions and Dispositions of Joint Ventures

During the three months ended March 31, 2011, one of the Funds in which we have a 20% interest acquired three multifamily properties for an aggregate net purchase price of approximately $122.6 million. The acquisitions were comprised of 352 units located in Houston, Texas; 355 units located in Dallas, Texas; and 234 units located in Atlanta, Georgia.

During March 2011, we sold our ownership interests in three unconsolidated joint ventures for total proceeds of approximately $19.3 million and recognized a gain of approximately $1.1 million. Two of the joint ventures own multifamily properties in Houston, Texas with 459 units, and one joint venture owns 6.1 acres of land in Houston, Texas which is in pre-development.

Development and Lease-Up Properties

We did not have any consolidated properties in lease-up at March 31, 2011.

At March 31, 2011, we had three consolidated properties under construction as follows:

							Included in		Estimated
	Number of						Properties		Date of		Estimated
($ in millions)	Apartment		Estimated		Cost		Under		Construction		Date of
Property and Location	Homes		Cost		Incurred		Development		Completion		Stabilization
Camden La Vina Orlando, FL		420	$	61.0	$	32.8	$	32.8		2Q12		3Q14

Total		711	$	107.0	$	48.7	$	48.7

Our condensed consolidated balance sheet at March 31, 2011 included approximately $220.6 million related to properties under development and land. Of this amount, approximately $48.7 million related to our projects currently under development. In addition, we had approximately $171.9 million primarily invested in land held for future development, which includes approximately $93.2 million related to projects we expect to begin constructing during the next two years, and approximately $78.7 million related to land tracts which we may develop in the future.

At March 31, 2011, we had an investment in an unconsolidated joint venture community which was in lease-up:

				Number of		Total		% Leased

Refer to Note 5, “Investments in Joint Ventures” in the notes to condensed consolidated financial statements for further discussion of our joint venture investments.

Results of Operations

Changes in revenues and expenses related to our operating properties from period to period are due primarily to the performance of stabilized properties in the portfolio, the lease-up of newly constructed properties, acquisitions, and dispositions. Where appropriate, comparisons of income and expense on communities included in continuing operations are made on a dollars-per-weighted average apartment home basis in order to adjust for such changes in the number of apartment homes owned during each period. Selected weighted averages for the three months ended March 31, 2011 and 2010 are as follows:

	Three Months Ended
	March 31,
($ in thousands)	2011			2010
Average monthly property revenue per apartment home	$	1,056		$	1,006
Annualized total property expenses per apartment home	$	5,026		$	4,997
Weighted average number of operating apartment homes owned 100%		50,881			49,512
Weighted average occupancy of operating apartment homes owned 100%		93.9	%		93.3	%

Property-level operating results

The following tables present the property-level revenues and property-level expenses, excluding discontinued operations, for the three months ended March 31, 2011 as compared to the same period in 2010:

Same store communities are communities we owned and were stabilized as of January 1, 2010. Non-same store communities are stabilized communities we have acquired, developed or re-developed after January 1, 2010. Development and lease-up communities are non-stabilized communities we have acquired or developed after January 1, 2010. Other includes results from non-multifamily rental properties and expenses relating to land holdings no longer under active development.

Same store analysis

Same store property revenues for the three months ended March 31, 2011 increased $5.3 million, or 3.7%, from the same period in 2010. Same store rental revenues for the three months ended March 31, 2011 increased $4.2 million from the same period in 2010 due to a 3.1% increase in average rental rates and a 0.5% increase in average occupancy for our same store portfolio which we believe is due in part to the continued decline in home ownership rates and the limited supply of new rental housing. Additionally, there was a $1.1 million increase for the three months ended March 31, 2011 in other property revenue primarily due to increases from our utility rebilling programs.

Property expenses from our same store communities increased $0.1 million, or 0.2%, for the three months ended March 31, 2011 as compared to the same period in 2010. The increase in same store property expenses was primarily due to increases in utility expenses, increased salaries and benefits due to increases in base salaries, and higher medical benefit costs, and slightly higher repairs and maintenance expenses. These increases were partially offset by lower real estate taxes as a result of declining property tax rates and property valuations at a number of our communities, and reduced property insurance costs due to lower self-insured property losses. Excluding the expenses associated with our utility rebilling programs, same store property expenses for this period decreased approximately $0.3 million, or 0.5%, as compared to the same period in 2010.

26

Non-same store analysis

Property revenues and expenses from non-same store and development and lease-up communities increased $6.4 million and $2.1 million, respectively, for the three months ended March 31, 2011 as compared to the same period in 2010. The increases during the period were primarily due to approximately $4.9 million of revenue and approximately $2.0 million of expense recognized during the three months ended March 31, 2011 related to three joint venture communities we consolidated during the second half of 2010, which were previously accounted for in accordance with the equity method of accounting. The increases were also related to two properties in our re-development and development pipelines reaching stabilization during the second and third quarters of 2010.

Other property analysis

Other property expenses decreased $0.2 million for the three months ended March 31, 2011 as compared to the same period in 2010. The decrease was primarily related to decreases in property taxes expensed on land holdings for five projects which were approved in 2010 and 2011 for development activities. As a result, we started capitalizing expenses, including property taxes, on these five projects.

Non-property income

	Three Months Ended

Total non-property income	$	12,563	$	8,365	$	4,198		50.2	%

Fee and asset management income was $1.8 million for each of the three month periods ended March 31, 2011 and 2010. Increases in property management fees due to acquisitions by one of the Funds were offset by a corresponding decrease due to our consolidation of three joint venture communities in the second half of 2010, which were previously accounted for in accordance with the equity method of accounting.

Interest and other income increased $1.7 million for the three months ended March 31, 2011 as compared to the same period in 2010. During the three months ended March 31, 2011, we recognized approximately $4.3 million in other income from the sale of our available-for-sale investment. During the three months ended March 31, 2010, we recognized approximately $2.7 million of other income relating to the expiration of an indemnification provision related to one of our operating joint ventures.

27

Income on deferred compensation plans increased $2.5 million for the three months ended March 31, 2011 as compared to the same period in 2010. This increase was related to the performance of the investments held in deferred compensation plans for participants and was directly offset by the expense related to these plans, as discussed below.

Total other expenses	$	100,367	$	92,512	$	7,855			8.5	%

Property management expense, which represents regional supervision and accounting costs related to property operations, increased approximately $0.1 million for the three months ended March 31, 2011 as compared to the same period in 2010. Property management expenses were 3.3% and 3.5% of total property revenues for the three months ended March 31, 2011 and 2010, respectively. The increase in 2011 was primarily due to an increase in training costs for our property management personnel.

Fee and asset management expense, which represents expenses related to third-party construction projects and property management, remained relatively flat for the three months ended March 31, 2011 as compared to the same period in 2010. This was primarily due to an increase in costs associated with additional properties acquired by the Fund during the second half of 2010 through the first quarter of 2011, which was offset by lower legal and other discretionary expenses during the three months ended March 31, 2011 as compared to the same period in 2010.

General and administrative expense increased $2.4 million for the three months ended March 31, 2011 as compared to the same period in 2010. This increase was primarily due to $2.1 million for one-time bonuses awarded to all non-executive employees, and an approximate $0.2 million increase in long-term incentive compensation during the three months ended March 31, 2011 as compared to the same period in 2010. Excluding the one-time bonus awards, general and administrative expenses were 4.6% and 4.8% of total property revenues and non-property income for the three months ended March 31, 2011 and 2010, respectively.

Interest expense for the three months ended March 31, 2011 decreased approximately $1.8 million as compared to the same period in 2010. The decrease was primarily due to retirement of maturing unsecured notes payable during 2010 and 2011. The decrease was also due to increased capitalized interest of approximately $0.5 million during the first quarter 2011 as compared to the same period in 2010 due to higher average balances in our development pipeline. These decreases were partially offset by an increase in secured notes payable relating to debt assumed in conjunction with the consolidation of two joint venture communities during the second half of 2010 which were previously accounted for using the equity method of accounting.

Depreciation and amortization increased $3.9 million for the three months ended March 31, 2011 as compared to the same period in 2010 due to an increase in new development and capital improvements placed in service during 2010, and the consolidation of three joint venture communities during the second half of 2010 which were previously accounted for using the equity method of accounting.

Amortization of deferred financing costs increased approximately $0.8 million for the three months ended March 31, 2011 as compared to the same period in 2010. This increase was primarily due to the amortization of the financing costs incurred on our $500 million unsecured credit facility entered into in August 2010.

Expense on deferred compensation plans increased $2.5 million during the three months ended March 31, 2011 as compared to the same period in 2010. This increase was related to the performance of the investments held in deferred compensation plans for participants and was directly offset by the income related to these plans, as discussed above.

Gain on sale of unconsolidated joint venture interests totaled approximately $1.1 million for the three months ended March 31, 2011 due to the sale of our ownership interests in three unconsolidated joint venture communities.

Equity in income (loss) of joint ventures increased approximately $0.5 million for the three months ended March 31, 2011 as compared to the same period in 2010. The increase was primarily the result of development properties held by our joint ventures reaching stabilization in late 2010 and early 2011 of approximately $0.5 million and an overall increase in earnings by our stabilized operating joint ventures of approximately $0.1 million primarily due to increases in rental income. These increases were partially offset by losses recognized by one of our Funds of approximately $0.2 million, primarily due to increased amortization of in-place leases over the underlying lease term.

During the three months ended March 31, 2011 and 2010, we incurred entity-level taxes for our operating partnerships and taxable REIT subsidiaries and other state and local taxes totaling approximately $1.3 million. The increase during the three months ended March 31, 2011 as compared to the same period in 2010 was due to approximately $1.0 million associated with income taxes associated with the gain recognized on the sale of our available-for-sale investment.

Income allocated to noncontrolling interests from continuing operations increased $0.8 million for the three months ended March 31, 2011 as compared to the same period in 2010. The increase was primarily due to an increase in earnings within a fully-consolidated joint venture which reached stabilization during the third quarter 2010, of which we retain a 25% ownership.

Funds from Operations (“FFO”)

Management considers FFO to be an appropriate measure of the financial performance of an equity REIT. The National Association of Real Estate Investment Trusts (“NAREIT”) currently defines FFO as net income (computed in accordance with GAAP), excluding gains (or losses) associated with the sale of previously depreciated operating properties, real estate depreciation and amortization, and adjustments for unconsolidated joint ventures. Our calculation of diluted FFO also assumes conversion of all potentially dilutive securities, including certain noncontrolling interests, which are convertible into common shares. We consider FFO to be an appropriate supplemental measure of operating performance because, by excluding gains or losses on dispositions of operating properties and depreciation, FFO can help in the comparison of the operating performance of a company’s real estate investments between periods or as compared to different companies.

29

To facilitate a clear understanding of our consolidated historical operating results, we believe FFO should be examined in conjunction with net income attributable to common shareholders as presented in the condensed consolidated statements of income and comprehensive income and data included elsewhere in this report. FFO is not defined by GAAP and should not be considered as an alternative to net income attributable to common shareholders as an indication of our operating performance. Additionally, FFO as disclosed by other REITs may not be comparable to our calculation.

Reconciliations of net income attributable to common shareholders to diluted FFO for the three months ended March 31, 2011 and 2010 are as follows:

Liquidity and Capital Resources

Financial Condition and Sources of Liquidity

We intend to maintain a strong balance sheet and preserve our financial flexibility, which we believe should enhance our ability to identify and capitalize on investment opportunities as they become available. We intend to maintain what management believes is a conservative capital structure by:

• extending and sequencing the maturity dates of our debt where practicable;

• managing interest rate exposure using what management believes to be prudent levels of fixed and floating rate debt;

• maintaining what management believes to be conservative coverage ratios; and

• using what management believes to be a prudent combination of debt and common and preferred equity.

Our interest expense coverage ratio, net of capitalized interest, was 2.9 and 2.5 times for the three months ended March 31, 2011, and 2010, respectively. This ratio is a method for calculating the amount of operating cash flows available to cover interest expense and is calculated by dividing interest expense for the period into the sum of property revenues and expenses, non-property income, other expenses, income from discontinued operations, after adding back depreciation, amortization, and interest expense from both continuing and discontinued operations. At March 31, 2011 and 2010, 71.2% and 72.8%, respectively, of our properties (based on invested capital) were unencumbered. Our weighted average maturity of debt, including our line of credit, was 5.5 years at March 31, 2011.

For the longer term, we intend to continue to focus on strengthening our capital and liquidity position by generating positive cash flows from operations, maintaining appropriate debt levels and leverage ratios, and controlling overhead costs.

30

Our primary source of liquidity is cash flow generated from operations. Other sources include available cash balances, the availability under our unsecured credit facility and other short-term borrowings, proceeds from dispositions of properties and other investments, and the use of debt and equity offerings under our automatic shelf registration statement. We believe our liquidity and financial condition are sufficient to meet all of our reasonably anticipated cash needs during 2011 including:

• normal recurring operating expenses;

• current debt service requirements;

• recurring capital expenditures;

• initial funding of property developments, acquisitions, and joint venture investments; and

• the minimum dividend payments required to maintain our REIT qualification under the Code.

Factors which could increase or decrease our future liquidity include but are not limited to volatility in capital and credit markets, sources of financing, our ability to complete asset sales, the effect our debt level and decreases in credit ratings could have on our costs of funds and our ability to access capital markets.

Cash Flows

Certain sources and uses of cash, such as the level of discretionary capital expenditures, and repurchases of debt and common shares are within our control and are adjusted as necessary based upon, among other factors, market conditions. The following is a discussion of our cash flows for the three months ended March 31, 2011 and 2010.

Net cash provided by operating activities was $54.4 million during the three months ended March 31, 2011 as compared to $41.8 million for the same period in 2010. The increase was primarily due to growth in property revenues from our stabilized communities. See further discussions of our first quarter 2011 operations as compared to 2010 in our “Results of Operations” discussion above. The increase in net cash from operating activities was also due to the timing of payments in operating accounts, primarily relating to accounts payable and accrued liabilities, offset by the $2.1 million payment of a one-time special bonus awarded to all non-executive employees during the three months ended March 31, 2011.

Net cash used in investing activities during the three months ended March 31, 2011 totaled $7.8 million as compared to $11.7 million during the three months ended March 31, 2010. Cash outflows for property development and capital improvements were $23.1 million during the three months ended March 31, 2011 as compared to $11.1 million for the same period in 2010 due primarily to an increase in construction and development activity in 2011 as compared to 2010. Additionally, cash outflows for investments in joint ventures were approximately $12.3 million during the three months ended March 31, 2011 as compared to $0.3 million during the same period in 2010. The cash outflow for 2011 primarily relates to three acquisitions made in the first quarter of 2011 by one of the Funds in which we own a 20% interest. These outflows were partially offset by proceeds received from the sale of our available-for-sale investment of $4.5 million, proceeds of $19.3 million from the sale of our interest in three unconsolidated joint venture communities and payments received on notes receivable from affiliates of approximately $3.3 million.

Net cash used in financing activities totaled $118.4 million for the three months ended March 31, 2011, primarily as a result of the repayment of maturing outstanding unsecured notes payable of $88.0 million, and distributions paid to common shareholders, perpetual preferred unit holders, and noncontrolling interest holders of $35.3 million. These cash outflows were partially offset by cash receipts of $3.8 million relating to proceeds received from the issuance of 0.1 million common shares under our ATM share offering program. Cash outflows were further offset by decreases in accounts receivable from affiliates of approximately $1.9 million relating to proceeds received from participant withdrawals from one of our deferred compensation plans. During the three months ended March 31, 2010, we used approximately $65.7 million in financing activities primarily to repay approximately $55.3 million of outstanding unsecured notes payable and distributions paid to common shareholders, perpetual preferred unit holders, and noncontrolling interest holders of $33.2 million. The cash outflows were partially offset by cash receipts of $17.2 million relating to proceeds received from the issuance of 0.4 million common shares under our ATM share offering program. Cash outflows were further offset by decreases in accounts receivable from affiliates of approximately $3.5 million relating to proceeds received from participant withdrawals from one of our deferred compensation plans and approximately $1.8 million for proceeds received from a construction loan for a consolidated joint venture.

Financial Flexibility

We have a $500 million unsecured credit facility, with the option to increase this credit facility to $600 million at our election, which matures in August 2012 and may be extended at our option to August 2013. Interest rate spreads float on a margin based on LIBOR and are subject to change as our credit ratings change. Advances under the line of credit may be priced at the scheduled rates, or we may enter into bid rate loans with participating banks at rates below the scheduled rates. These bid rate loans have terms of 180 days or less and may not exceed the lesser of $250 million or the remaining amount available under the line of credit. The line of credit is subject to customary financial covenants and limitations, all of which we are in compliance.

Our line of credit provides us with the ability to issue up to $100 million in letters of credit. While our issuance of letters of credit does not increase our borrowings outstanding under our line of credit, it does reduce the amount available. At March 31, 2011, we had outstanding letters of credit totaling approximately $10.2 million, and had approximately $489.8 million available under our unsecured line of credit.

We currently have an automatic shelf registration statement on file with the SEC which allows us to offer, from time to time, an unlimited amount of common shares, preferred shares, debt securities, or warrants. Our declaration of trust provides we may issue up to 110.0 million shares of beneficial interest, consisting of 100.0 million common shares and 10.0 million preferred shares. As of March 31, 2011, we had approximately 70.0 million common shares outstanding, net of treasury shares and shares held in our deferred compensation plans, and no preferred shares outstanding.

In March 2010, we originated our ATM share offering program through which we may, but have no obligation to, sell common shares having an aggregate offering price of up to $250 million from time to time into the existing trading market at current market prices as well as through negotiated transactions. We may, but shall have no obligation to, sell common shares through the ATM share offering program in amounts and at times as we determine. Actual sales from time to time may depend on a variety of factors including, among others, market conditions, the trading price of our common shares and determinations of the appropriate sources of funding for us. During the three months ended March 31, 2011, we issued 0.1 million common shares at an average price of $54.06 per share for total net consideration of approximately $3.8 million. In April 2011, we issued an additional 0.2 million common shares at an average price of $56.50 per share for total net considerations of approximately $10.1 million. Cumulative to date, we have issued approximately 5.1 million common shares at an average price of $48.73 for total net consideration of approximately $245.3 million. As of the date of this filing, we had common shares having an aggregate offering price of up to $0.5 million remaining available for sale under the ATM program.

We believe our ability to access capital markets is enhanced by our senior unsecured debt ratings by Moody’s and Standard and Poor’s, which are currently Baa1 and BBB, respectively, with stable outlooks, as well as by our ability to borrow on a secured basis from various institutions including banks, Fannie Mae, Freddie Mac, or life insurance companies. However, we may not be able to maintain our current credit ratings and may not be able to borrow on a secured or unsecured basis in the future.

Future Cash Requirements and Contractual Obligations

One of our principal long-term liquidity requirements includes the repayment of maturing debt, including any future borrowings under our unsecured line of credit. During the remainder of 2011, approximately $66.5 million of debt, excluding scheduled principal amortizations of $3.3 million, is scheduled to mature. Additionally, we have construction commitments of approximately $56.6 million of additional capital expenditures on our current development projects and we expect to fund these amounts through available cash balances and draws on our unsecured line of credit. We intend to meet our near-term liquidity requirements through available cash balances, cash flows generated from operations, draws on our unsecured credit facility, proceeds from property dispositions, and the use of debt and equity offerings under our automatic shelf registration statement.

In order for us to continue to qualify as a REIT, we are required to distribute annual dividends to our shareholders equal to a minimum of 90% of our REIT taxable income, computed without regard to the dividends paid deduction and our net capital gains. In March 2011, we announced our Board of Trust Managers had declared a quarterly dividend of $0.49 per share, which represented a $0.04 per share increase from the previous $0.45 per share dividend, to our common shareholders of record as of March 31, 2011. The dividend was subsequently paid on April 18, 2011, and we paid equivalent amounts per unit to holders of the common operating partnership units. Assuming similar dividend distributions for the remainder of 2011, our annualized dividend rate for 2011 would be $1.96 per share or unit.

32

Off-Balance Sheet Arrangements

The joint ventures in which we have an interest have been funded in part with secured, third-party debt. As of March 31, 2011, we have no outstanding guarantees related to loans utilized for construction and development activities for our unconsolidated joint ventures.

Inflation

Substantially all of our apartment leases are for a term generally ranging from six to fifteen months. In an inflationary environment, we may realize increased rents at the commencement of new leases or upon the renewal of existing leases. We believe the short-term nature of our leases generally minimizes our risk from the adverse effects of inflation.

Critical Accounting Policies

Our critical accounting policies have not changed materially from information reported in our Annual Report on Form 10-K for the year ended December 31, 2010.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

No material changes to our exposures to market risk have occurred since our Annual Report on Form 10-K for the year ended December 31, 2010.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. We carried out an evaluation, under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report pursuant to Securities Exchange Act (“Exchange Act”) Rules 13a-15(e) and 15d-15(e). Based on the evaluation, the Chief Executive Officer and Chief Financial Officer concluded the disclosure controls and procedures as of the end of the period covered by this report are effective to ensure information required to be disclosed by us in our Exchange Act filings is recorded, processed, summarized, and reported within the periods specified in the Securities and Exchange Commission’s rules and forms.

Changes in Internal Controls. There were no changes in our internal control over financial reporting (identified in connection with the evaluation required by paragraph (d) in Rules 13a-15 and 15d-15 under the Exchange Act) during our most recent fiscal quarter which have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
