Item 1. |  | Business

General Development of 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. Unless the context requires otherwise, “we,” “our,” “us,” and the “Company” refer to Camden Property Trust and its consolidated subsidiaries. Our multifamily apartment communities are referred to as “communities,” “multifamily communities,” “properties,” or “multifamily properties” in the following discussion.
Our executive offices are located at 3 Greenway Plaza, Suite 1300, Houston, Texas 77046 and our telephone number is (713) 354-2500. Our website is located at www.camdenliving.com. On our website we make available free of charge our annual, quarterly, and current reports, and amendments to such reports, filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the Securities and Exchange Commission (the “SEC”). We also make available, free of charge on our website, our Guidelines on Governance, Code of Business Conduct and Ethics, Code of Ethical Conduct for Senior Financial Officers, and the charters of each of our Audit, Compensation, Nominating, and Corporate Governance Committees.
Our annual, quarterly, and current reports, proxy statements, and other information are electronically filed with the SEC. You may read and copy any materials we file with the SEC at the SEC’s Public Reference Room at 100 F Street, NE, Washington, D.C. 20549. Please contact the SEC at 1-800-SEC-0330 for further information about the operation of the SEC’s Public Reference Room. The SEC also maintains a website at www.sec.gov which contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC.
Financial Information about Segments
We are primarily engaged in the ownership, management, development, acquisition, and construction of multifamily apartment communities. As each of our communities has similar economic characteristics, residents, amenities, and services, our operations have been aggregated into one reportable segment. See our consolidated financial statements and notes included thereto in Item 15 of this Annual Report on Form 10-K for certain information required by Item 1.
Narrative Description of Business
As of December 31, 2010, we owned interests in, operated, or were developing 188 multifamily properties comprising 63,923 apartment homes across the United States. Of these 188 properties, two properties were under development and when completed will consist of a total of 607 apartment homes. In addition, we own land parcels we may develop into multifamily apartment communities.
Operating Strategy
We believe producing consistent earnings growth through property operations, development and acquisitions, achieving market balance, and recycling capital are crucial factors to our success. We rely heavily on our sophisticated property management capabilities and innovative operating strategies to help us maximize the earnings potential of our communities.
Real Estate Investments and Market Balance. We believe we are well positioned in our current markets and have the expertise to take advantage of new opportunities as they arise. These capabilities, combined with what we believe is a conservative financial structure, should allow us to concentrate our growth efforts toward selective opportunities to enhance our strategy of having a geographically diverse portfolio of assets which meet the requirements of our residents.
We continue to operate in our core markets which we believe provides an advantage due to economies of scale. We believe, where possible, it is best to operate with a strong base of properties in order to benefit from the personnel allocation and the market strength associated with managing several properties in the same market. However, consistent with our goal of generating sustained earnings growth, we intend to selectively dispose of properties and redeploy capital for various strategic reasons, including if we determine a property cannot meet long-term earnings growth expectations.

##### Table of Contents

Subject to market conditions, we intend to continue to look for opportunities to develop and acquire existing communities through our discretionary investment funds (the “Funds”), expand our development pipeline, and complete selective dispositions.
We intend to continue to focus on strengthening our capital and liquidity positions by generating positive cash flows from operations, reducing outstanding debt 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 secured mortgage notes, and the use of debt and equity offerings under our automatic shelf registration statement.
Sophisticated Property Management. We believe the depth of our organization enables us to deliver quality services, promote resident satisfaction, and retain residents, thereby reducing operating expenses. We manage our properties utilizing a staff of professionals and support personnel, including certified property managers, experienced apartment managers and leasing agents, and trained apartment maintenance technicians. Our on-site personnel are trained to deliver high quality services to our residents. We strive to motivate our on-site employees through incentive compensation arrangements based upon property operational results, rental rate increases, and level of lease renewals achieved.
Operations. We believe an intense focus on operations is necessary to realize consistent, sustained earnings growth. Ensuring resident satisfaction, increasing rents as market conditions allow, maximizing rent collections, maintaining property occupancy at optimal levels, and controlling operating costs comprise our principal strategies to maximize property financial results. We believe our web-based property management and revenue management systems strengthen on-site operations and allow us to quickly adjust rental rates as local market conditions change. Lease terms are generally staggered based on vacancy exposure by apartment type so lease expirations are matched to each property’s seasonal rental patterns. We generally offer leases ranging from six to fifteen months with individual property marketing plans structured to respond to local market conditions. In addition, we conduct ongoing customer service surveys to ensure timely response to residents’ changing needs and a high level of satisfaction.
Investments in Joint Ventures. We have entered into, and may continue in the future to enter into, joint ventures through which we own an indirect economic interest of less than 100% of the community or communities owned directly by the joint venture. See Note 8, “Investments in Joint Ventures,” and Note 14, “Commitments and Contingencies,” of the Notes to Consolidated Financial Statements for further discussion of our investments in joint ventures.
Competition
There are numerous housing alternatives which compete with our communities in attracting residents. Our properties compete directly with other multifamily properties as well as with condominiums and single-family homes which are available for rent or purchase in the markets in which our communities are located. This competitive environment could have a material adverse effect on our ability to lease apartment homes at our present communities or any newly developed or acquired community, as well as on the rents charged.
Employees
At December 31, 2010, we had approximately 1,750 employees, including executive, administrative, and community personnel.
Qualification as a Real Estate Investment Trust
As of December 31, 2010, we met the qualification of a REIT under Sections 856-860 of the Internal Revenue Code of 1986, as amended (the “Code”). As a result, we, with the exception of our taxable REIT subsidiaries, will not be subject to federal income tax to the extent we continue to meet certain requirements of the Code.

Item 1A. |  | Risk Factors

In addition to the other information contained in this Form 10-K, the following risk factors should be considered carefully in evaluating our business. Our business, financial condition, or results of operations could be materially adversely affected by any of these risks. Additional risks not presently known to us, or which we currently consider immaterial, may also impair our business and operations.
Risks Associated with Real Estate, Real Estate Capital, and Credit Markets
Volatility in capital and credit markets, or other unfavorable changes in economic conditions could adversely impact us.
The capital and credit markets experienced volatility and disruption particularly in the latter half of 2008 through the first quarter of 2010. This caused the spreads on prospective debt financings to fluctuate and made it more difficult to borrow money. In the event of renewed market disruption and volatility, we may not be able to obtain new debt financing or refinance our existing debt on favorable terms or at all, which would adversely affect our liquidity, our ability to make distributions to shareholders, acquire and dispose of assets and continue our development pipeline. Other weakened economic conditions, including job losses and high unemployment rates have adversely affected rental rates and occupancy levels. Unfavorable changes in economic conditions may have a material adverse impact on our cash flows and operating results.
Additional key economic risks which may affect conditions in the markets in which we operate include the following:

| • |  | local conditions, such as an oversupply of apartments or other housing available for rent, or a reduction in demand for apartments in the area;

| • |  | declines in the financial condition of our tenants, which may make it more difficult for us to collect rents from some tenants;

| • |  | changes in market rental rates;

| • |  | declines in mortgage interest rates and home pricing, making alternative housing more affordable;

| • |  | government or builder incentives which enable home buyers to put little or no money down, making alternative housing options more attractive;

| • |  | regional economic downturns which simultaneously affect one or more of our geographical markets; and

| • |  | increased operating costs, if these costs cannot be passed through to residents.

Short-term leases expose us to the effects of declining market rents.
Substantially all of our apartment leases are for a term of fifteen months or less. As these leases generally permit the residents to leave at the end of the lease term without penalty, our rental revenues are impacted by declines in market rents more quickly than if our leases were for longer terms.
We face risks associated with land holdings and related activities.
We hold land for future development and may in the future acquire additional land holdings. The risks inherent in purchasing, owning, and developing land increase as demand for apartments, or rental rates, decrease. Real estate markets are highly uncertain and, as a result, the value of undeveloped land has fluctuated significantly and may continue to fluctuate. In addition, carrying costs can be significant and can result in losses or reduced profitability. As a result, we hold certain land, and may in the future acquire additional land, in our development pipeline at a cost we may not be able to fully recover or at a cost which precludes our developing a profitable multifamily community. Given the uncertainty and volatility of the current economic environment, there is less market information available to us to utilize in estimating the fair value of our holdings; if additional market information becomes available in future periods which impacts our estimates of fair value, we may be required to take future impairment charges.

##### Table of Contents

Difficulties of selling real estate could limit our flexibility.
We intend to continue to evaluate the potential disposition of assets which may no longer meet our objectives. When we decide to sell an asset, we may encounter difficulty in finding buyers in a timely manner as real estate investments generally cannot be disposed of quickly, especially when market conditions are poor. These factors may limit our ability to vary our portfolio promptly in response to changes in economic or other conditions and may also limit our ability to utilize sales proceeds as a source of liquidity, which would adversely affect our ability to make distributions to shareholders or repay debt. In addition, the provisions of the Code relating to REITs limit our ability to earn a gain on the sale of property (unless we own the property through a subsidiary which will incur a taxable gain upon sale) if we have held the property less than two years, and this limitation may affect our ability to sell properties without adversely affecting returns to shareholders.
We could be negatively impacted by the condition of Fannie Mae or Freddie Mac.
Fannie Mae and Freddie Mac are a major source of financing for secured multifamily real estate. We and other multifamily companies depend heavily on Fannie Mae and Freddie Mac to finance growth by purchasing or guaranteeing apartment loans. In February 2011, the Obama administration released a report proposing Fannie Mae and Freddie Mac be gradually eliminated. The report proposed three possible courses for long-term reform of housing finance. A final decision by the government to eliminate Fannie Mae or Freddie Mac or reduce their acquisitions or guarantees of apartment loans may adversely affect interest rates, capital availability, and the development of multifamily communities.
Compliance or failure to comply with laws requiring access to our properties by disabled persons could result in substantial cost.
The Americans with Disabilities Act (“ADA”), the Fair Housing Amendments Act of 1988 (“FHAA”), and other federal, state, and local laws, rules, and regulations generally require public accommodations and apartment homes be made accessible to disabled persons. Noncompliance could result in the imposition of fines by the government or the award of damages to private litigants. These laws may require us to modify our existing properties. These laws may also restrict renovations by requiring improved access to such buildings by disabled persons or may require us to add other structural features which increase our construction costs. Legislation or regulations adopted in the future may impose further costs and obligations or restrictions on us with respect to improved access by disabled persons. We may incur unanticipated expenses which may be material to our financial condition or results of operations to comply with ADA, FHAA, and other federal, state, and local laws, or in connection with lawsuits brought by the government or private litigants.
Competition could limit our ability to lease apartments or increase or maintain rental income.
There are numerous housing alternatives which compete with our properties in attracting residents. Our properties compete directly with other multifamily properties as well as condominiums and single family homes which are available for rent or purchase in the markets in which our properties are located. This competitive environment could have a material adverse effect on our ability to lease apartment homes at our present properties or any newly developed or acquired property, as well as on the rents charged.
Risks Associated with Our Operations
Development and construction risks could impact our profitability.
We intend to continue to develop and construct multifamily apartment communities for our portfolio, and expect higher levels of development activity in 2011 as compared to recent years. Our development and construction activities may be exposed to a number of risks which may increase our construction costs and decrease our profitability including the following:

| • |  | inability to obtain, or delays in obtaining, necessary zoning, land-use, building, occupancy, and other required permits and authorizations;

4

##### Table of Contents

| • |  | increased materials, labor, problems with subcontractors, or other costs due to errors and omissions which occur in the design or construction process;

| • |  | inability to obtain financing with favorable terms for the development of a community;

| • |  | inability to complete construction and lease-up of a community on schedule;

| • |  | the expected occupancy and rental rates may differ from the actual results;

| • |  | incurring costs related to the abandonment of development opportunities which we have pursued and subsequently deemed unfeasible; and

| • |  | inability to successfully implement our development and construction strategy could adversely affect our results of operations and our ability to satisfy our financial obligations and pay distributions to shareholders.

One of our wholly-owned subsidiaries is engaged in the business of providing general contracting services under construction contracts entered into between it and third-parties (including nonconsolidated subsidiaries). The terms of those construction contracts generally require this subsidiary to estimate the time and costs to complete a project, and to assume the risk the time and costs associated with its performance may be greater than anticipated. As a result, profitability on those contracts is dependent on the ability to accurately predict such factors. The time and costs necessary to complete a project may be affected by a variety of factors, including those listed above, many of which are beyond this subsidiary’s control. In addition, the terms of those contracts generally require this subsidiary to warrant its work for a period of time during which it may be required to repair, replace, or rebuild defective work. Further, additional trailing liabilities, based on various legal theories such as claims of negligent construction, may result from such projects, and these trailing liabilities may go on for a number of years depending on the length of the statutes of repose in various jurisdictions.
Our acquisition strategy may not produce the cash flows expected.
Subject to the requirements of the Funds, we may acquire additional operating properties on a select basis. Our acquisition activities are subject to a number of risks, including the following:

| • |  | we may not be able to successfully integrate acquired properties into our existing operations;

| • |  | our estimates of the costs, if any, of repositioning or redeveloping the acquired property may prove inaccurate;

| • |  | the expected occupancy and rental rates may differ from the actual results; and

| • |  | we may not be able to obtain adequate financing.

With respect to acquisitions of operating companies, we may not be able to identify suitable candidates on terms acceptable to us or may not achieve expected returns and other benefits as a result of integration challenges, such as personnel and technology.
Competition could adversely affect our ability to acquire properties.
We expect other real estate investors, including insurance companies, pension and investment funds, private investors, and other apartment REITs, will compete with us to acquire additional operating properties. This competition could increase prices for the type of properties we would likely pursue and adversely affect our ability to acquire these properties or the profitability of such properties upon acquisition.
Losses from catastrophes may exceed our insurance coverage.
We carry comprehensive property and liability insurance on our properties, which we believe is of the type and amount customarily obtained on similar real property assets by similar types of owners. We intend to obtain similar coverage for properties we acquire or develop in the future. However, some losses, generally of a catastrophic nature such as losses from floods, hurricanes, or earthquakes, may be subject to coverage limitations. We exercise our discretion in determining amounts, coverage limits, and deductible provisions of insurance to maintain appropriate insurance on our investments at a reasonable cost and on suitable terms. If we suffer a substantial loss, our insurance coverage may not be sufficient to pay the full current market value or current replacement value of our lost investment, as well as the anticipated future revenues from the property. Inflation, changes in building codes and ordinances, environmental considerations, and other factors also may reduce the feasibility of using insurance proceeds to replace a property after it has been damaged or destroyed.

##### Table of Contents

Investments through joint ventures involve risks not present in investments in which we are the sole investor.
We have invested and may continue to invest as a joint venture partner in joint ventures. These investments involve risks, including the possibility the other joint venture partner may have business goals which are inconsistent with ours, be in a position to take action or withhold consent contrary to our requests, or become insolvent and require us to assume and fulfill the joint venture’s financial obligations. We and our joint venture partner may each have the right to initiate a buy-sell arrangement, which could cause us to sell our interest, or acquire our joint venture partner’s interest, at a time when we otherwise would not have entered into such a transaction. Each joint venture agreement is individually negotiated, and our ability to operate, finance, and/or dispose of a community in our sole discretion may be limited to varying degrees depending on the terms of the joint venture agreement.
We face risks associated with investments in and management of discretionary funds.
We have formed the Funds which, through wholly-owned subsidiaries, we manage as the general partner and advisor. We have committed to invest 20% of the total equity interest in each of the Funds, up to $75 million in the aggregate; each of the Funds has total capital commitments of $187.5 million or $375 million in the aggregate. There are risks associated with the investment in and management of the Funds, including the following:

| • |  | investors in the Funds may fail to make their capital contributions when due and, as a result, the Funds may be unable to execute their investment objectives;

| • |  | the general partner of the Funds, our wholly-owned subsidiary, has unlimited liability for the third-party debts, obligations, and liabilities of the Funds pursuant to partnership law;

| • |  | investors in the Funds (other than us), by majority vote, may remove our subsidiary as the general partner of the Funds with or without cause and the Funds’ advisory boards, by a majority vote of their members, may remove our subsidiary as the general partner of the Funds at any time for cause;

| • |  | while we have broad discretion to manage the Funds and make investment decisions on behalf of the Funds, the investors or the advisory boards must approve certain matters, and as a result we may be unable to cause the Funds to make certain investments or implement certain decisions we consider beneficial;

| • |  | we are permitted to acquire land and develop communities outside of the Funds, but are generally prohibited from acquiring fully developed multifamily properties outside of the Funds until the earlier of (i) April 8, 2012, or (ii) such time as 90% of the Funds’ committed capital is invested, subject to certain exceptions;

| • |  | our ability to redeem all or a portion of our investments in the Funds is subject to significant restrictions; and

| • |  | we may be liable if the Funds fail to comply with various tax or other regulatory matters.

We depend on our key personnel.
Our success depends in part on our ability to attract and retain the services of executive officers and other personnel. There is substantial competition for qualified personnel in the real estate industry, and the loss of several of our key personnel could have an adverse effect on us.

##### Table of Contents

Changes in litigation risks could affect our business.
As a large publicly-traded owner of multifamily properties, we may become involved in legal proceedings, including consumer, employment, tort, or commercial litigation, which if decided adversely to or settled by us, could result in liability which is material to our financial condition or results of operations.
Tax matters, including failure to qualify as a REIT, could have adverse consequences.
We may not continue to qualify as a REIT in the future. The Internal Revenue Service may challenge our qualification as a REIT for prior years and new legislation, regulations, administrative interpretations, or court decisions may change the tax laws or the application of the tax laws with respect to qualification as a REIT or the federal tax consequences of such qualification.
For any taxable year we fail to qualify as a REIT and do not qualify under statutory relief provisions:

| • |  | we would be subject to federal income tax on our taxable income at regular corporate rates, including any applicable alternative minimum tax;

| • |  | we would be disqualified from treatment as a REIT for the four taxable years following the year in which we failed to qualify, thereby reducing our net earnings available for operations, including any distributions to shareholders, as we would be required to pay significant income taxes for the year or years involved; and

| • |  | our ability to expand our business and raise capital would be impaired, which may adversely affect the value of our common shares.

We may face other tax liabilities in the future which may impact our cash flow. These potential tax liabilities may be calculated on our income or property values at either the corporate or individual property levels. Any additional tax expense incurred would decrease the cash available for distribution to our shareholders.
Risks Associated with Our Indebtedness and Financing
Insufficient cash flows could limit our ability to make required payments for debt obligations or pay distributions to shareholders.
Substantially all of our income is derived from rental and other income from our multifamily communities. As a result, our performance depends in large part on our ability to collect rent from residents, which could be negatively affected by a number of factors, including the following:

| • |  | delay in resident lease commencements;

| • |  | decline in occupancy;

| • |  | failure of residents to make rental payments when due;

| • |  | the attractiveness of our properties to residents and potential residents;

| • |  | our ability to adequately manage and maintain our communities;

| • |  | competition from other available apartments and housing alternatives; and

| • |  | changes in market rents.

Cash flow could be insufficient to meet required payments of principal and interest with respect to debt financing. 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. This requirement limits the cash flow available to meet required principal payments on our debt.

##### Table of Contents

We have significant debt, which could have important adverse consequences.
As of December 31, 2010, we had outstanding debt of approximately $2.6 billion. This indebtedness could have important consequences, including:

| • |  | if a property is mortgaged to secure payment of indebtedness, and if we are unable to meet our mortgage obligations, we could sustain a loss as a result of foreclosure on the mortgaged property;

| • |  | our vulnerability to general adverse economic and industry conditions is increased; and

| • |  | our flexibility in planning for, or reacting to, changes in business and industry is limited.

The mortgages on our properties subject to secured debt, our unsecured credit facility, and the indentures under which our unsecured debt was issued contain customary restrictions, requirements, and other limitations, as well as certain financial and operating covenants including maintenance of certain financial ratios. Maintaining compliance with these provisions could limit our financial flexibility. A default in these provisions, if uncured, could require us to repay the indebtedness before the scheduled maturity date, which could adversely affect our liquidity and increase our financing costs.
We may be unable to renew, repay, or refinance our outstanding debt.
We are subject to the risk that indebtedness on our properties or our unsecured indebtedness will not be renewed, repaid, or refinanced when due or the terms of any renewal or refinancing will not be as favorable as the existing terms of such indebtedness. If we are unable to refinance our indebtedness on acceptable terms, or at all, we might be forced to dispose of one or more of the properties on disadvantageous terms, which might result in losses to us. Such losses could have a material adverse effect on us and our ability to make distributions to our shareholders and pay amounts due on our debt. Furthermore, if a property is mortgaged to secure payment of indebtedness and we are unable to meet mortgage payments, the mortgagee could foreclose on the property, appoint a receiver and exercise rights under an assignment of rents and leases, or pursue other remedies, all with a consequent loss of our revenues and asset value. Foreclosures could also create taxable income without accompanying cash proceeds, thereby hindering our ability to meet the REIT distribution requirements of the Code.
Variable rate debt is subject to interest rate risk.
We have mortgage debt with varying interest rates dependent upon various market indexes. In addition, we have a revolving credit facility bearing interest at a variable rate on all amounts drawn on the facility. We may incur additional variable rate debt in the future. Increases in interest rates on variable rate debt would increase our interest expense, unless we make arrangements which hedge the risk of rising interest rates, which would adversely affect net income and cash available for payment of our debt obligations and distributions to shareholders.
We may incur losses on interest rate hedging arrangements.
Historically, we have entered into agreements to reduce the risks associated with changes in interest rates, and we may continue to do so in the future. Although these agreements may partially protect against rising interest rates, they may also reduce the benefits to us if interest rates decline. If a hedging arrangement is not indexed to the same rate as the indebtedness which is hedged, we may be exposed to losses to the extent which the rate governing the indebtedness and the rate governing the hedging arrangement change independently of each other. Additionally, nonperformance by the other party to the hedging arrangement may subject us to increased credit risks.
Issuances of additional debt may adversely impact our financial condition.
Our capital requirements depend on numerous factors, including the rental and occupancy rates of our apartment properties, dividend payment rates to our shareholders, development and capital expenditures, costs of operations, and potential acquisitions. If our capital requirements vary materially from our plans, we may require additional financing earlier than anticipated. If we issue more debt, we could become more leveraged, resulting in increased risk of default on our obligations and an increase in our debt service requirements, both of which could adversely affect our financial condition and ability to access debt and equity capital markets in the future.

##### Table of Contents

Failure to maintain our current credit ratings could adversely affect our cost of funds, related margins, liquidity, and access to capital markets.
Moody’s and Standard & Poor’s, the major debt rating agencies, routinely evaluate our debt and have given us ratings of Baa1 and BBB, respectively, with stable outlooks, on our senior unsecured debt. These ratings are based on a number of factors, which include their assessment of our financial strength, liquidity, capital structure, asset quality, and sustainability of cash flow and earnings. Due to changes in market conditions, we may not be able to maintain our current credit ratings, which could adversely affect our cost of funds and related margins, liquidity, and access to capital markets.
Risks Associated with Our Shares
Share ownership limits and our ability to issue additional equity securities may prevent takeovers beneficial to shareholders.
For us to maintain our qualification as a REIT, we must have 100 or more shareholders during the year and not more than 50% in value of our outstanding shares may be owned, directly or indirectly, by five or fewer individuals. As defined for federal income tax purposes, the term “individuals” includes a number of specified entities. To minimize the possibility of us failing to qualify as a REIT under this test, our declaration of trust includes restrictions on transfers of our shares and ownership limits. The ownership limits, as well as our ability to issue other classes of equity securities, may delay, defer, or prevent a change in control. These provisions may also deter tender offers for our common shares which may be attractive to you or limit your opportunity to receive a premium for your shares which might otherwise exist if a third party were attempting to effect a change in control transaction.
Our share price will fluctuate.
The market price and trading volume of our common shares are subject to fluctuation due to general market conditions, the risks discussed in this report and other matters, including the following:

| • |  | operating results which vary from the expectations of securities analysts and investors;

| • |  | investor interest in our property portfolio;

| • |  | the reputation and performance of REITs;

| • |  | the attractiveness of REITs as compared to other investment vehicles;

| • |  | the results of our financial condition and operations;

| • |  | the perception of our growth and earnings potential;

| • |  | dividend payment rates;

| • |  | increases in market interest rates, which may lead purchasers of our common shares to demand a higher yield; and

| • |  | changes in financial markets and national economic and general market conditions.

The form, timing and/or amount of dividend distributions in future periods may vary and be impacted by economic and other considerations.
The form, timing and/or amount of dividend distributions will be declared at the discretion of our Board of Trust Managers and will depend on actual cash from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Code and other factors as the Board of Trust Managers may consider relevant. The Board of Trust Managers may modify the form, timing and/or amount of dividends from time to time.

As of February 17, 2011, there were 585 shareholders of record and approximately 19,335 beneficial owners of our common shares.
In January 2008, our Board of Trust Managers approved an increase of the April 2007 repurchase plan to allow for the repurchase of up to $500 million of our common equity securities through open market purchases, block purchases, and privately negotiated transactions. Under this program, we have repurchased 4.3 million shares for a total of approximately $230.2 million from April 2007 through December 31, 2010. The remaining dollar value of our common equity securities authorized to be repurchased under the program was approximately $269.8 million as of December 31, 2010. There were no repurchases of our equity securities during the year ended December 31, 2010.
In March 2010, we announced the creation of an at-the-market (“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, in amounts and at times as we determine, into the existing trading market at current market prices as well as through negotiated transactions. 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 year ended December 31, 2010, we issued approximately 4.9 million common shares at an average price of $48.37 per share for total net consideration of approximately $231.7 million. In January 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. As of the date of this filing, we had common shares having an aggregate offering price of up to $10.7 million remaining available for sale under the ATM program.
See Part III, Item 12, for a description of securities authorized for issuance under equity compensation plans.

(a) |  | Excludes discontinued operations.
(b) |  | Management considers Funds from Operations (“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 accounting principles generally accepted in the United States of America (“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 excluding depreciation, FFO can assist in the comparison of the operating performance of a company’s real estate between periods or as compared to different companies.
(c) |  | Includes discontinued operations.
(d) |  | Excludes apartment homes owned in joint ventures.

Item 7. |  | Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the consolidated financial statements and notes appearing elsewhere in this report. Historical results and trends which might appear in the consolidated financial statements should not be interpreted as being indicative of future operations.
We consider portions of this report to be “forward-looking” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, both as amended, with respect to our expectations for future periods. Forward-looking statements do not discuss historical fact, but instead include statements related to expectations, projections, intentions, or other items relating to the future; forward-looking statements are not guarantees of future performances, results, or events. Although we believe the expectations reflected in our forward-looking statements are based upon reasonable assumptions, we can give no assurance our expectations will be achieved. Any statements contained herein which are not statements of historical fact should be deemed forward-looking statements. Reliance should not be placed on these forward-looking statements as they are subject to known and unknown risks, uncertainties, and other factors beyond our control and could differ materially from our actual results and performance.
Factors that may cause our actual results or performance to differ materially from those contemplated by forward-looking statements include, but are not limited to, the following:

| • |  | volatility in capital and credit markets, or other unfavorable changes in economic conditions could adversely impact us;

| • |  | short-term leases expose us to the effects of declining market rents;

| • |  | we face risks associated with land holdings and related activities;

| • |  | difficulties of selling real estate could limit our flexibility;

| • |  | we could be negatively impacted by the condition of Fannie Mae or Freddie Mac;

| • |  | compliance or failure to comply with laws requiring access to our properties by disabled persons could result in substantial cost;

| • |  | competition could limit our ability to lease apartments or increase or maintain rental income;

| • |  | development and construction risks could impact our profitability;

| • |  | our acquisition strategy may not produce the cash flows expected;

| • |  | competition could adversely affect our ability to acquire properties;

| • |  | losses from catastrophes may exceed our insurance coverage;

| • |  | investments through joint ventures involve risks not present in investments in which we are the sole investor;

| • |  | we face risks associated with investments in and management of discretionary funds;

| • |  | we depend on our key personnel;

| • |  | changes in litigation risks could affect our business;

| • |  | tax matters, including failure to qualify as a REIT, could have adverse consequences;

| • |  | insufficient cash flows could limit our ability to make required payments for debt obligations or pay distributions to shareholders;

| • |  | we have significant debt, which could have important adverse consequences;

| • |  | we may be unable to renew, repay, or refinance our outstanding debt;

| • |  | variable rate debt is subject to interest rate risk;

| • |  | we may incur losses on interest rate hedging arrangements;

| • |  | issuances of additional debt may adversely impact our financial condition;

| • |  | failure to maintain our current credit ratings could adversely affect our cost of funds, related margins, liquidity, and access to capital markets;

| • |  | share ownership limits and our ability to issue additional equity securities may prevent takeovers beneficial to shareholders;

| • |  | our share price will fluctuate; and

| • |  | the form, timing and/or amount of dividend distributions in future periods may vary and be impacted by economic or other considerations.

These forward-looking statements represent our estimates and assumptions as of the date of this report, and we assume no obligation to update or supplement forward-looking statements because of subsequent events.

Executive Summary
We are primarily engaged in the ownership, management, development, acquisition and construction of multifamily apartment communities. As of December 31, 2010, we owned interests in, operated, or were developing 188 multifamily properties comprising 63,923 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.
The U.S. economy has experienced a significant recession. Record levels of job losses and higher unemployment rates negatively impacted our business, particularly in the latter half of 2008 through the first quarter of 2010, when we experienced declines in both rental rates and occupancy levels. Despite unemployment rates remaining at high levels, our results for the most recent three quarters reflect sequential rental revenue growth as well as an increase in rental revenue growth for the three months ended December 31, 2010 as compared to the same period in 2009, primarily due to improvements in rental rates and slight improvements in 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 2010, we acquired three multifamily properties, totaling 686 units, for an aggregate of approximately $63.0 million on behalf of one of our discretionary investment funds in which we have a 20% ownership interest. Additionally, we restructured three of our joint ventures, which collectively own an aggregate of 1,069 units, resulting in our acquiring a controlling ownership interest in each joint venture.
During the second half of 2010, we began construction on two development projects, comprised of approximately 607 units; initial occupancy is expected in the last half of 2011. As of December 31, 2010, we intend to incur approximately $57.2 million of additional costs on these projects. We expect to fund these amounts through available cash balances and draws upon our unsecured line of credit. We expect to start several additional development projects currently held in our development pipeline in 2011 and are evaluating additional development projects to commence during fiscal year 2011 and beyond.
During the fourth quarter of 2010, we received net proceeds of approximately $101.9 million and recognized a gain of approximately $9.6 million from the sale of two operating properties, containing 1,066 apartment homes to unaffiliated third parties.
Subject to market conditions, we intend to continue to look for opportunities to develop and acquire existing communities through the Funds, expand our development pipeline, and complete selective dispositions. We also intend to continue to focus on strengthening our capital and liquidity positions by generating positive cash flows from operations, reducing outstanding debt 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 secured mortgage notes, and the use of debt and equity offerings under our automatic shelf registration statement.
As of December 31, 2010, we had approximately $170.6 million in cash and cash equivalents and no balances outstanding on our $500 million unsecured line of credit. We have approximately $154.4 million of 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. During the year ended December 31, 2010, stabilization was achieved at four recently completed development properties as follows:

|  | Number of |  |  | Date of |  |  |  |
|  | Apartment |  |  | Construction |  |  | Date of |
Property and Location |  | Homes |  |  | Completion |  |  | Stabilization |

(1) |  | Camden Travis Street is a fully-consolidated joint venture, of which we retain a 25% ownership

Partial Sales and Dispositions to Joint Ventures Included in Continuing Operations
There were no partial sales or dispositions to joint ventures for the years ended December 31, 2010 or 2009.
In March 2008, we sold a development community in Austin, Texas, to one of the Funds for approximately $8.9 million. No gain or loss was recognized on the sale. In August 2008, we sold a stabilized community to the same Fund for approximately $44.2 million and recognized a gain of approximately $1.8 million on the sale.
Discontinued Operations
We intend to maintain a long-term strategy of managing our invested capital through the selective sale of properties and to utilize the proceeds to reduce our outstanding debt and leverage ratios and fund investments with higher anticipated growth prospects in our markets. Income from discontinued operations includes the operations of properties sold during the year ended December 31, 2010. The components of earnings classified as discontinued operations include separately identifiable property-specific revenues, expenses, depreciation, and interest expense, if any. Any gain or loss on the disposal of the properties held for sale is also classified as discontinued operations.
A summary of our 2010 dispositions is as follows:

During the year ended December 31, 2010, we recognized a gain of approximately $0.2 million from the sale of land in Houston, Texas. During the year ended December 31, 2008, we recognized a gain of approximately $1.1 million from the sale of land adjacent to our regional office in Las Vegas, Nevada. The gains on these sales were not included in discontinued operations as the operations and cash flows of these assets were not clearly distinguished, operationally or for reporting purposes, from the adjacent assets.
Development and Lease-Up Properties
We did not have any consolidated properties in lease-up at December 31, 2010.

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 years ended December 31 are as follows:

|  | 2010 |  |  | 2009 |  |  | 2008 |
Average monthly property revenue per apartment home |  | $ | 1,021 |  |  | $ | 1,036 |  |  | $ | 1,058 |
Annualized total property expenses per apartment home |  | $ | 4,970 |  |  | $ | 4,920 |  |  | $ | 4,862 |
Weighted average number of consolidated operating apartment homes |  |  | 49,801 |  |  |  | 49,206 |  |  |  | 48,246 |
Weighted average occupancy of consolidated operating apartment homes |  |  | 93.4 | % |  |  | 94.6 | % |  |  | 93.9 | %

Same store analysis:
Same store property revenues for the year ended December 31, 2010 decreased approximately $11.4 million, or 2.0%, from 2009. Same store rental revenues decreased approximately $11.8 million for the year ended December 31, 2010 as compared to 2009, primarily due to a 2.3% decline in average rental rates from 2009 for our same store portfolio during 2010, partially offset by a slight increase in average occupancy. The decline in average rental rates was due to the continuation of the recession through the first quarter of 2010, offset by improving rental rates and slight improvements in average occupancy levels for the most recent three quarters which we believe is due in part to the continued decline in home ownership rates and the limited supply of new rental housing. The decrease was also partially offset by a $0.4 million increase in other property revenue primarily due to increases from our utility rebilling programs.
Same store property revenues for the year ended December 31, 2009 decreased approximately $16.8 million, or 3.2%, from 2008. Same store rental revenues decreased approximately $23.9 million, or 5.2%, from 2008 due to a slight decline in average occupancy and a 5.0% decline in average rental rates for our same store portfolio due to, among other factors, the challenges within the multifamily industry resulting from a significant recession experienced within the U.S. This decrease was partially offset by an approximate $7.1 million increase in other property revenue primarily due to the continued rollout of our utility rebilling programs.

##### Table of Contents

Property expenses from our same store communities increased approximately $0.8 million, or 0.4%, for the year ended December 31, 2010, as compared to 2009. The increase was primarily due to expenses related to our utility rebilling programs discussed above, higher salaries, and increases in property insurance and repair and maintenance costs. These increases were partially offset by lower real estate taxes as a result of declining rates and valuations at a number our communities. Excluding the expenses associated with our utility rebilling programs, same store property expenses for 2010 decreased approximately $0.8 million, or 0.4%, from 2009.
Property expenses from our same store communities increased approximately $3.4 million, or 1.8%, for the year ended December 31, 2009, as compared to 2008. This increase was primarily due to expenses related to our utility rebilling programs discussed above and increases in property insurance costs. This increase was partially offset by lower property taxes resulting from declining rates and valuations at a number of our communities, and lower repair and maintenance, and marketing and leasing, expenses. Excluding the expenses associated with our utility rebilling programs, same store property expenses for 2009 declined approximately $0.2 million, or 0.1% from 2008.
Non-same store and development and lease-up analysis:
Property revenues from non-same store and development and lease-up communities increased approximately $10.3 million for the year ended December 31, 2010 as compared to 2009 and increased approximately $19.1 million for the year ended December 31, 2009 as compared to 2008. The increase in 2010 as compared to 2009 was primarily due to seven consolidated properties in our development and re-development pipelines reaching stabilization during 2009 and 2010, in addition to approximately $2.6 million of revenues recognized in the second half of 2010 related to three newly consolidated joint ventures as more fully described in Note 7, “Property Acquisitions, Discontinued Operations, and Impairments.” The increase in 2009 as compared to 2008 was primarily due to nine consolidated properties in our development and re-development pipelines reaching stabilization during 2008 and 2009.
Property expenses from non-same store and development and lease-up communities increased approximately $3.0 million for the year ended December 31, 2010 as compared to 2009 and increased approximately $5.3 million for 2009 as compared to 2008. The increases in both periods were due to a number of consolidated properties in our development and re-development pipelines reaching stabilization as discussed above. The increase in 2010 was also due to approximately $1.1 million of expenses recognized in the second half of 2010 related to three newly consolidated joint ventures as more fully described in Note 7, “Property Acquisitions, Discontinued Operations, and Impairments.”
Other property analysis:
Other property revenues decreased approximately $0.6 million and $2.7 million for the year ended December 31, 2010 as compared to 2009 and for the year ended December 31, 2009 as compared to 2008, respectively. The decrease for 2009 as compared to 2008 was primarily due to the sale of one of our communities to one of the Funds in 2008.
Other property expenses increased approximately $1.6 million for the year ended December 31, 2010 as compared to 2009 and decreased $1.3 million for the year ended December 31, 2009 as compared to 2008, respectively. The increases in 2010 as compared to 2009 primarily related to increases in property taxes expensed on land holdings for eight projects for which we decided in 2009 to postpone development. As a result, we ceased capitalization of expenses, including property taxes. The decrease in 2009 as compared to 2008 was primarily due to costs we incurred related to Hurricane Ike in September 2008.

Fee and asset management income, which represents income related to asset management, third-party construction and development projects and property management, increased approximately $0.2 million for the year ended December 31, 2010 as compared to 2009 and decreased approximately $1.2 million for the year ended December 31, 2009 as compared to 2008. The increase for 2010 was primarily related to an increase in third-party construction activities, offset by decreases in development and construction fees earned on our development joint ventures as compared to 2009 due to the completion of construction activities during 2009 and 2010. The increase was further offset by decreases in fees earned on our stabilized joint ventures due to declines in property revenues. The decrease for 2009 was primarily related to overall declines in development and construction fees earned on our development joint ventures in 2009 as compared to 2008 due to the completion of the associated construction activities at several joint venture communities in 2008 and 2009. The decrease in 2009 was partially offset by an increase in third-party construction activities in 2009.
Interest and other income increased approximately $5.8 million for 2010 as compared to 2009 and decreased approximately $1.9 million for 2009 as compared to 2008. The increase for 2010 was primarily due to the recognition of approximately $2.7 million of other income resulting from indemnification provisions in an operating joint venture agreement which expired in January 2010, and recognition of approximately $4.2 million of other income as a result of the dissolution of a joint venture and purchase by our joint venture partner of the third-party debt made by this joint venture from the note holder, which relieved us from our guarantee of our proportionate interest of this debt; we had previously recorded a charge for this indemnification. These increases were partially offset by an approximate $0.9 million decrease in interest income due to declines in interest income on our mezzanine loan portfolio related primarily to the lower balances of outstanding mezzanine loans due in part to conversion of mezzanine loans into additional equity interests in certain of our joint ventures in 2009 and 2010.
The $1.9 million decrease in 2009 as compared to 2008 was primarily due to declines in interest income on our mezzanine loan portfolio related to contractual reductions in interest rates, reductions in interest earned on certain variable rate mezzanine notes due to declines in LIBOR, and lower balances of outstanding mezzanine loans due in part to the conversion of mezzanine loans into additional equity interests in certain of our joint ventures in 2009.
Our deferred compensation plans earned income of approximately $11.6 million and $14.6 million in 2010 and 2009, respectively, and incurred losses of $33.4 million in 2008. The changes were related to the performance of the investments held in the deferred compensation plans for plan participants and were directly offset by the expense (benefit) related to these plans, as set forth in the table below.

Property management expense, which represents regional supervision and accounting costs related to property operations, increased approximately $1.1 million for the year ended December 31, 2010 as compared to 2009 and decreased approximately $1.0 million for 2009 as compared to 2008. Property management expenses were 3.3%, 3.1%, and 3.3% of total property revenues for the years ended December 31, 2010, 2009, and 2008, respectively. The $1.1 million increase in 2010 was primarily due to increases in salary and benefits, rental, marketing, and travel expenses as compared to 2009. The decrease in 2009 as compared to 2008 was due primarily to lower travel and legal expenses.
Fee and asset management expense, which represents expenses related to asset management, third-party construction and development projects and property management, was relatively flat in 2010 as compared to 2009 due in part to an increase in third-party construction activities, offset by decreases in development and construction on our development joint ventures as compared to 2009 due to the completion of construction activities during 2009 and 2010. The $1.2 million decrease for 2009 as compared to 2008 was primarily due to declines in development and construction activities related to our development joint ventures in 2009 as compared to 2008 due to the completion of the associated construction activities at several joint venture communities in 2008 and 2009.
General and administrative expenses decreased approximately $0.5 million during the year ended December 31, 2010 as compared to 2009 and decreased approximately $0.3 million during the year ended December 31, 2009 as compared to 2008. General and administrative expenses were 4.9% of total revenues, excluding income or loss on deferred compensation plans, for the year ended December 31, 2010, and 5.0% for each of the years ended December 31, 2009, and 2008. The decrease in 2010 as compared to 2009 was primarily due to a decrease in legal costs and other discretionary expenses, $1.6 million in severance payments made in connection with a reduction in force of certain construction and development staff in January 2009, and separation costs relating to the retirement of one executive officer during the fourth quarter of 2009. These decreases were partially offset by an increase in long-term incentive compensation of approximately $1.6 million during 2010 as compared to 2009. The decrease for 2009 as compared to 2008 was primarily due to various cost-saving initiatives implemented in 2009, and increased expenses in 2008 which did not recur in 2009 associated with the abandonment of potential acquisitions. The decrease was partially offset by $1.6 million in severance payments made in connection with the reduction in force of certain construction and development staff in 2009, and separation costs relating to the retirement of one executive officer during the fourth quarter of 2009.
Interest expense decreased approximately $2.4 million during the year ended December 31, 2010 as compared to 2009 and decreased approximately $4.1 million during the year ended December 31, 2009 as compared to 2008. The decrease in 2010 was primarily due to using the net proceeds of $272.1 million from the equity offering completed during the second quarter of 2009 and approximately $231.7 million in net proceeds from our ATM program during 2010 to retire outstanding debt, prior to its maturity, of approximately $325.0 million during the first six months of 2009 and repay maturing secured and unsecured notes during 2009 and 2010, as well as reduce the balances outstanding on our unsecured line of credit. This decrease was partially offset by the increased interest expense incurred on our $420 million credit facility entered into during the second quarter of 2009 and lower capitalized interest of approximately $4.6 million in 2010 as compared to 2009 primarily due to the completion of communities in our development pipeline and our decision in fiscal year 2009 to postpone the development of land holdings for eight future projects.

The decrease for 2009 as compared to 2008 was primarily due to decreases in indebtedness as a result of early retirement of outstanding debt of approximately $325.0 million during the first six months of 2009. This decrease in interest expense was partially offset by a decrease in capitalized interest of approximately $7.4 million during the year ended December 31, 2009 as compared to 2008 as a result of the completion of units in our development pipeline and our decision in fiscal year 2008 not to continue with five future development projects. The decrease was further offset by higher interest rates on existing indebtedness resulting from paying down amounts outstanding under our unsecured line of credit with proceeds from our $420 million credit facility entered into in April 2009 and our $380 million credit facility entered into in September 2008.
Depreciation and amortization expense increased approximately $1.5 million during the year ended December 31, 2010 as compared to 2009 and increased approximately $2.8 million during the year ended December 31, 2009 as compared to 2008. The increase in 2010 as compared to 2009 was primarily due to new development and capital improvements placed in service during 2009 and 2010 and the consolidation of three joint ventures during the second half of 2010, which were previously accounted for under the equity method of accounting. These increases were partially offset by an increase in the number of assets being fully depreciated in 2010 as compared to 2009. The increase in 2009 as compared to 2008 was primarily due to completion of new development and capital improvements placed in service in 2009 as compared to the previous year.
Amortization of deferred financing costs increased approximately $0.2 million during the year ended December 31, 2010 as compared to 2009 and increased approximately $1.0 million during the year ended December 31, 2009 as compared to 2008. The increase for 2010 as compared to 2009 was primarily due to additional financing costs incurred on our $500 million unsecured credit facility, entered into in August 2010, and on our $420 million credit facility, entered into the second quarter of 2009. These increases were partially offset by lower amortization of deferred financing costs related to the repurchase and retirement of certain series of notes during 2010 and 2009. The increase for 2009 as compared to 2008 was primarily due to the amortization of our financing costs incurred upon the extension of our unsecured credit facility in October 2009, and financing costs related to our $380 million credit facility completed in September 2008 and our $420 million credit facility completed in April 2009. This increase was partially offset by the repurchase and retirement of certain series of notes during 2009.
Our deferred compensation plans incurred expenses of approximately $11.6 million and $14.6 million in 2010 and 2009, respectively, and earned a benefit of approximately $33.4 million in 2008. The changes were related to the performance of the investments held in the deferred compensation plans for plan participants and were directly offset by the income (loss) related to these plans, as discussed above.

Gain on sale of properties, including land, totaled approximately $0.2 million and $2.9 million for the years ended December 31, 2010 and December 31, 2008, respectively. The gain in 2008 was due to the partial sale of properties to one of the Funds and a gain on the sale of a land parcel in Las Vegas, Nevada to an unaffiliated third party. There was no gain on sale of properties, including land, for the year ended December 31, 2009.

Loss on early retirement of debt was approximately $2.6 million for the year ended December 31, 2009 due to the repurchase and retirement of approximately $325.0 million of various unsecured and secured notes from unrelated third parties for approximately $327.5 million during the first two quarters of 2009. Gain on early retirement of debt was approximately $13.6 million for the year ended December 31, 2008 due to the repurchases and retirements of debt, including a tender offer for certain series of outstanding debt which resulted in the repurchase and retirement of approximately $108.3 million of debt from unrelated third parties for approximately $100.6 million, and the repurchases and retirements of approximately $82.7 million of various series of other outstanding debt from unrelated third parties for approximately $75.7 million. The gain (loss) on early retirement of debt for these transactions also includes reductions for the write-off of applicable loan costs. There was no gain (loss) on early retirement of debt for the year ended December 31, 2010.
The impairment associated with land development activities for the year ended December 31, 2009 of approximately $85.6 million includes approximately $72.2 million related to land holdings for eight projects, and approximately $13.4 million related to a land development joint venture we put on hold. The impairment associated with land development activities for the year ended December 31, 2008 of approximately $51.3 million reflects impairments in the value of land holdings for several potential development projects, including approximately $48.6 million related to land holdings for five projects, approximately $1.6 million in the value of a land parcel held for future development, and approximately $1.1 million for costs capitalized for a potential joint venture development we did not develop. These impairment charges for land are the difference between each parcel’s estimated fair value and the carrying value. There were no impairments associated with land development activities for the year ended December 31, 2010.
During the fourth quarter of 2010, we wrote-off a $1.0 million investment associated with a technology investment which we determined was no longer recoverable.
Equity in income (loss) of joint ventures decreased approximately $1.5 million for the year ended December 31, 2010 as compared to 2009, and increased approximately $2.0 million for the year ended December 31, 2009 as compared to 2008. The decrease for 2010 as compared to 2009 was primarily the result of decreases in earnings by our stabilized operating joint ventures due to declines in rental income, and the recognition of net operating losses by certain development joint ventures during the lease-up phase of operations. The decreases were further impacted by the consolidation of three operating joint ventures during the second half of 2010, which were previously accounted for in accordance with the equity method of accounting. These decreases were partially offset by increases in earnings in development joint ventures reaching or nearing stabilization during 2009 and 2010. The increase for 2009 as compared to 2008 was primarily the result of certain properties owned by development joint ventures reaching or nearing stabilization in 2009 partially offset by declining earnings at our stabilized operating joint ventures due to declines in rental income.
We had current income tax expense of approximately $1.6 million, $1.0 million, and $0.8 million for the tax years ended December 31, 2010, 2009, and 2008, respectively. The increase in taxes in 2010 as compared to 2009 primarily related to an increase in federal income taxes resulting from increased profitability in our construction activities conducted in a taxable REIT subsidiary. The increase in taxes in 2009 as compared to 2008 primarily related to an increase in state income taxes.

Income allocated to noncontrolling interests from continuing operations increased approximately $1.3 million in 2010 as compared to 2009, and decreased $4.5 million in 2009 as compared to 2008. During 2009, we recognized an approximately $72.2 million impairment associated with land holdings for eight projects we had put on hold, of which $3.6 million represented certain operating partnerships’ interests of the impairment. Excluding this impairment charge, income allocated to noncontrolling interests from continuing operations decreased approximately $2.3 million and $0.8 million in 2010 as compared to 2009, and 2009 as compared to 2008, respectively. The $2.3 million decrease in 2010 as compared to 2009 was primarily due to the completion during the three months ended March 31, 2010 and subsequent lease-up of a property by a fully consolidated joint venture of which we retain a 25% ownership, which resulted in our recording depreciation and interest expense on the property, upon completion of construction, in excess of income recognized during the lease-up period. The decrease was also due to lower earnings associated with properties held by operating partnerships during 2010 as compared to 2009. The $0.8 million decrease in 2009 was primarily due to lower earnings associated with properties held by operating partnerships during 2009 as compared to 2008.

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 accounting principles generally accepted in the United States of America (“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 one compare the operating performance of a company’s real estate between periods or as compared to different companies.
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 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 years ended December 31 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 approximately 2.6 times for each of the years ended December 31, 2010, 2009, and 2008. Our interest expense coverage ratio 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. This ratio is a method for calculating the amount of operating cash flows available to cover interest expense. At December 31, 2010, 2009, and 2008, approximately 71.1%, 72.8%, and 78.3%, 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 December 31, 2010.
For the longer term, we intend to continue to focus on strengthening our capital and liquidity position by generating positive cash flows from operations, reducing outstanding debt and leverage ratios, and controlling overhead costs.
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, secured mortgage debt, 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, joint venture investments, and notes receivable; 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 years ended December 31, 2010 and 2009.
Net cash provided by operating activities was approximately $224.0 million during the year ended December 31, 2010 as compared to approximately $217.7 million during the year ended December 31, 2009. The increase was primarily due to lower interest expense and changes in operating accounts. The increase was partially offset by declines in property net operating income in 2010 as compared to 2009.
Net cash provided by investing activities during the year ended December 31, 2010 totaled approximately $35.2 million as compared to net cash used by investing activities of approximately $69.5 million during the year ended December 31, 2009. Cash outflows for property development, acquisition, and capital improvements were approximately $63.7 million during 2010 as compared to approximately $72.8 million during 2009. This decrease was due to the timing of completions of communities in our development pipeline and a reduction in construction and development activity in 2010 as compared to 2009. Cash inflows from sales of properties including land and discontinued operations were approximately $102.8 million for the year ended December 31, 2010 as compared to approximately $28.1 million for the year ended December 31, 2009. Additionally, cash outflows for investments in joint ventures were $6.5 million for the year ended December 31, 2010 as compared to $23.2 million in 2009. The decrease in cash outflows for investments in joint ventures in 2010 as compared to 2009 was primarily a result of our $22.2 million equity investment in one of our joint ventures during the third quarter 2009.

##### Table of Contents

Net cash used in financing activities totaled approximately $152.8 million during the year ended December 31, 2010 primarily as a result of the repayment of maturing outstanding unsecured notes payable of approximately $137.6 million, repayment of approximately $165.6 million of secured notes assumed in connection with obtaining controlling interests in three joint ventures and distributions paid to common shareholders, perpetual preferred unit holders, and noncontrolling interest holders of approximately $135.6 million. The cash outflows were partially offset by cash receipts of approximately $231.7 million relating to proceeds received from the sale of approximately 4.9 million common shares throughout fiscal year 2010 under our ATM share offering program. Cash outflows were further offset by decreases in accounts receivable from affiliates of approximately $4.2 million relating to proceeds received from participant withdrawals from our deferred compensation plans and approximately $53.0 million for proceeds received from secured notes payable relating to a secured credit agreement for a newly consolidated joint venture and $4.7 million for advances under a construction loan for one of our communities completing construction during 2010. Net cash provided by financing activities totaled approximately $91.4 million during the year ended December 31, 2009. During the year ended December 31, 2009, we used a total of approximately $648.7 million of cash to repay outstanding notes payable consisting of approximately $169.9 million of outstanding notes payable stemming from our April 2009 tender offer, the early retirement of outstanding debt consisting of approximately $139.1 million of secured notes, and approximately $18.2 million of senior unsecured notes. The remaining outstanding notes payable payments were primarily for maturing secured and unsecured notes payable of approximately $176.5 million, and payments of all remaining amounts outstanding on our unsecured line of credit. Also in 2009, $152.7 million was used for distributions paid to common shareholders, perpetual preferred unit holders, and noncontrolling interest holders. The cash outflows were offset by cash receipts of $420 million from a secured credit facility entered into during the second quarter, approximately $20.8 million of cash receipts from secured notes relating to a construction loan for a consolidated joint venture and net proceeds of approximately $272.1 million from the completion of our equity offering in May 2009.
Financial Flexibility
In August 2010, we entered into a $500 million unsecured credit facility, with the option to increase this credit facility to $600 million, which matures in August 2012 and may be extended at our option to August 2013. This facility replaces our $600 million unsecured credit facility which was scheduled to mature in January 2011. 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 December 31, 2010, we had outstanding letters of credit totaling approximately $10.2 million, leaving 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 million shares of beneficial interest, consisting of 100 million common shares and 10 million preferred shares. As of December 31, 2010, we had approximately 69.6 million common shares outstanding, net of treasury shares and shares held in our deferred compensation arrangements, and no preferred shares outstanding.
In March 2010, we announced the creation of 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, in amounts and at times as we determine, into the existing trading market at current market prices as well as through negotiated transactions. 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. As of the day of this filing, we had common shares having an aggregate offering price of up to $10.7 million remaining 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 2011, approximately $154.4 million of unsecured debt, excluding scheduled principal amortizations, are scheduled to mature. See Note 9, “Notes Payable,” of the Notes to Consolidated Financial Statements for further discussion of scheduled maturities. Additionally, we intend to incur approximately $57.2 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 secured mortgage notes, 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 December 2010, we announced our Board of Trust Managers had declared a dividend distribution of $0.45 per share to our common shareholders of record as of December 20, 2010. The dividend was subsequently paid on January 18, 2011. We paid equivalent amounts per unit to holders of common operating partnership units. When aggregated with previous 2010 dividends, this distribution to common shareholders and holders of common operating partnership units equates to an annual dividend rate of $1.80 per share or unit for the year ended December 31, 2010.
The following table summarizes our known contractual cash obligations as of December 31, 2010:

(in millions) |  | Total |  |  | 201 1 |  |  | 201 2 |  |  | 201 3 |  |  | 201 4 |  |  | 201 5 |  |  | Thereafter |

(1) |  | Includes scheduled principal amortizations.
(2) |  | Includes contractual interest payments for our senior unsecured notes, medium-term notes, and secured notes. Interest payments on hedged loans were calculated based on the interest rates effectively fixed by the interest rate swap agreements. The interest payments on certain secured notes with floating interest rates were calculated based on the interest rates in effect as of December 31, 2010 or the most recent practicable date.

Off-Balance Sheet Arrangements
The joint ventures in which we have an interest have been funded in part with secured, third-party debt. We have guaranteed no more than our proportionate interest, totaling approximately $11.0 million, of two loans utilized for construction and development activities for our joint ventures. We are also committed to additional funding under a mezzanine loan provided to one joint venture and our commitment to fund additional amounts under this mezzanine loan was an aggregate of approximately $6.0 million at December 31, 2010.
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
The preparation of our financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the balance sheet date, and the amounts of revenues and expenses recognized during the reporting period. These estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances. The following is a discussion of our critical accounting estimates. For a discussion of all of our significant accounting policies, see Note 2 to the accompanying consolidated financial statements.

##### Table of Contents

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 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.
Principles of Consolidation. We may enter into various joint venture agreements with unrelated third parties to hold or develop real estate assets. We must determine for each of these joint ventures whether to consolidate the entity or account for our investment under the equity or cost basis of accounting. 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 in 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. We evaluate our accounting for investments on a quarterly basis or when a reconsideration event (as defined in GAAP) with respect to our investments occurs. The analysis required to identify VIEs and primary beneficiaries is complex and requires substantial management judgment. Accordingly, we believe the decisions made to choose an appropriate accounting framework are critical.
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 that maximize inputs from a marketplace participant’s perspective.
In addition, we evaluate our 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.
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.
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 our 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. Included in capitalized costs are management’s estimates of indirect costs associated with our development and redevelopment activities. The estimates used by management require judgment, and accordingly we believe cost capitalization to be a critical accounting estimate.

Item 7A. |  | Quantitative and Qualitative Disclosures About Market Risk

We are exposed to certain market risks inherent in our operations. These risks generally arise from transactions entered into in the normal course of business. We believe our primary market risk exposure relates to interest rate risk. We do not enter into derivatives or other financial instruments for trading or speculative purposes.
The table below provides information about our assets and our liabilities sensitive to changes in interest rates as of December 31, 2010 and 2009:

|  | December 31, 2010 |  |  | December 31, 2009 |
|  |  |  |  |  | Weighted |  |  | Weighted |  |  |  |  |  |  |  |  |  |  | Weighted |  |  | Weighted |  |  |  |

|  | (in millions) |  |  | (in years) |  |  | Rate |  |  | Total |  |  | (in millions) |  |  | (in years) |  |  | Rate |  |  | Total |
Fixed rate debt (1) |  | $ | 2,333.5 |  |  |  | 5.2 |  |  |  | 5.4 | % |  |  | 91.0 | % |  | $ | 2,396.8 |  |  |  | 5.2 |  |  |  | 5.5 | % |  |  | 91.3 | %
Variable rate debt |  |  | 230.3 |  |  |  | 9.0 |  |  |  | 1.3 |  |  |  | 9.0 |  |  |  | 228.4 |  |  |  | 10.1 |  |  |  | 1.2 |  |  |  | 8.7 |

(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 an interest rate swap (see discussion below).

We have historically used variable rate indebtedness available under our revolving credit facility to initially fund acquisitions and our development pipeline. To the extent we utilize our revolving credit facility thereby increasing our variable rate indebtedness, our exposure to increases in interest rates will also increase.
For fixed rate debt, interest rate changes affect the fair market value but do not impact net income attributable to common shareholders or cash flows. Conversely, for floating rate debt, interest rate changes generally do not affect the fair market value but do impact net income attributable to common shareholders and cash flows, assuming other factors are held constant. Holding other variables constant, a one percentage point variance in interest rates would change the unrealized fair market value of the fixed rate debt by approximately $94.6 million. The net income attributable to common shareholders and cash flows impact on the next year resulting from a one percentage point variance in interest rates on floating rate debt, excluding debt effectively fixed by interest rate swap agreements described below, would be approximately $2.3 million, holding all other variables constant. We currently use interest rate hedges to reduce the impact of interest rate fluctuations on certain variable indebtedness, not for trading or speculative purposes. Under the hedge agreements:

| • |  | we agree to pay a counterparty the interest that would have been incurred on a fixed principal amount at a fixed interest rate; and

| • |  | the counterparty agrees to pay us the interest rate that would have been incurred on the same principal amount at an assumed floating interest rate tied to a particular market index.

As of December 31, 2010, the effect of our hedge agreements was to fix the interest rate on approximately $516.6 million of our variable rate debt. Had the hedge agreements not been in place during 2010, our annual interest costs would have been approximately $23.3 million lower, based on balances and reported interest rates through the year as the variable interest rates were less than the effective interest rates on the associated hedge agreements. Additionally, if the variable interest rates on this debt had been 100 basis points higher through 2010 and the hedge agreements not been in place, our annual interest cost would have been approximately $5.8 million higher. Derivative financial instruments 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 dealing 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, thus minimizing credit risk concentration. We believe the likelihood of realized losses from counterparty non-performance is remote.

Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934 as follows:
A process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of trustees, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

| • |  | Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;

| • |  | Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

| • |  | Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2010. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.
Based on our assessment, management concluded our internal control over financial reporting is effective as of December 31, 2010.
Deloitte & Touche LLP, an independent registered public accounting firm, has issued an attestation report regarding the effectiveness of our internal controls over financial reporting, which is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Trust Managers and Shareholders of
Camden Property Trust
Houston, Texas
We have audited the internal control over financial reporting of Camden Property Trust and subsidiaries (the “Company”) as of December 31, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of trust managers, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and the board of trust managers of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule of the Company as of and for the year ended December 31, 2010 and our report dated February 24, 2011 expressed an unqualified opinion on those financial statements and financial statement schedule.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Trust Managers and Shareholders of
Camden Property Trust
Houston, Texas
We have audited the accompanying consolidated balance sheets of Camden Property Trust and subsidiaries (the “Company”) as of December 31, 2010 and 2009, and the related consolidated statements of income and comprehensive income, equity, and cash flows for each of the three years in the period ended December 31, 2010. Our audits also included the financial statement schedule listed in the Index at Item 15. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Camden Property Trust and subsidiaries as of December 31, 2010 and 2009, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2010, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 24, 2011 expressed an unqualified opinion on the Company’s internal control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Description of 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 December 31, 2010, we owned interests in, operated, or were developing 188 multifamily properties comprising 63,923 apartment homes across the United States. Of these 188 properties, two properties were under development and when completed will consist of a total of 607 apartment homes. In addition, we own land parcels we may develop into multifamily apartment communities.
2. Summary of Significant Accounting Policies and Recent Accounting Pronouncements
Principles of Consolidation. Our 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.
Allocations of Purchase Price. Upon the acquisition of real estate, we allocate the purchase price between tangible and intangible assets, which includes land, buildings, furniture and fixtures, the value of in-place leases, including above and below market leases, and acquired liabilities. When allocating the purchase price to acquired properties, we allocate costs to the estimated intangible value of in-place leases and above or below market leases and to the estimated fair value of furniture and fixtures, land, and buildings on a value determined by assuming the property was vacant by applying methods similar to those used by independent appraisers of income-producing property. Depreciation is computed on a straight-line basis over the remaining useful lives of the related tangible assets. The value of in-place leases and above or below market leases is amortized over the estimated average remaining life of leases in place at the time of acquisition. The unamortized value of in-place leases at December 31, 2010, was approximately $3.9 million. Amortization expense will be recognized over the remaining life of these in-place leases in 2011. Estimates of fair value of acquired debt are based upon interest rates available for the issuance of debt with similar terms and remaining maturities.
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 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.

F-9

##### Table of Contents

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 $5.7 million, $10.3 million, and $17.7 million for the years ended December 31, 2010, 2009, and 2008, respectively. Capitalized real estate taxes were approximately $0.8 million, $1.9 million, and $3.4 million for the years ended December 31, 2010, 2009, and 2008, respectively.
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 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.

##### Table of Contents

Discontinued Operations. A property is classified as a discontinued operation when (i) the operations and cash flows of the property can be clearly distinguished and have been or will be eliminated from our ongoing operations; (ii) the property has either been disposed of or is classified as held for sale; and (iii) we will not have any significant continuing involvement in the operations of the property after the disposal transactions. Significant judgments are involved in determining whether a property meets the criteria for discontinued operations reporting and the period in which these criteria are met. A property is classified as held for sale when (i) management commits to a plan to sell and it is actively marketed; (ii) it is available for immediate sale in its present condition and the sale is expected to be completed within one year; and (iii) it is unlikely significant changes to the plan will be made or the plan will be withdrawn. In isolated instances, assets held for sale may exceed one year due to events or circumstances beyond our control.
The results of operations for properties sold during the period or classified as held for sale at the end of the current period are classified as discontinued operations in the current and prior periods. The property-specific components of earnings classified as discontinued operations include separately identifiable property-specific revenues, expenses, depreciation, and interest expense, if any. The gain or loss resulting from the eventual disposal of the held for sale properties is also classified within discontinued operations. Real estate assets held for sale are measured at the lower of carrying amount or fair value less costs to sell and are presented separately in the accompanying consolidated balance sheets. Subsequent to classification of a property as held for sale, no further depreciation is recorded. Properties sold by our unconsolidated entities are not included in discontinued operations and related gains or losses are reported as a component of equity in income (loss) of joint ventures.
Gains on sale of real estate are recognized using the full accrual or partial sale methods, as applicable, in accordance with accounting principles generally accepted in the United States of America (“GAAP”), provided various criteria relating to the terms of sale and any subsequent involvement with the real estate sold are met.
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. Eight 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.
Insurance. Our primary lines of insurance coverage are property, general liability, and health and workers’ compensation. We believe our insurance coverage adequately insures our properties against the risk of loss attributable to fire, earthquake, hurricane, tornado, flood, and other perils and adequately insures us against other risks. Losses are accrued based upon our estimates of the aggregate liability for claims incurred using certain actuarial assumptions followed in the insurance industry and based on our experience.
Other Assets, Net. Other assets in our consolidated financial statements include investments under deferred compensation plans, deferred financing costs, non-real estate leasehold improvements and equipment, prepaid expenses, the value of in-place leases net of related accumulated amortization, available-for-sale investments, and other miscellaneous receivables. Investments under deferred compensation plans are classified as trading securities and are adjusted to fair market value at period end. See further discussion of our investments under deferred compensation plans in Note 11, “Share-based Compensation and Benefit Plans.” Deferred financing costs are amortized no longer than the terms of the related debt on the straight-line method, which approximates the effective interest method. Corporate leasehold improvements and equipment are depreciated using the straight-line method over the shorter of the expected useful lives or the lease terms which range from three to ten years. Our available-for-sale investments are carried at fair value with unrealized gains and losses included in accumulated other comprehensive income (loss), a separate component of shareholders’ equity.
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 97% of our total property revenues and total non-property income, excluding income (loss) on deferred compensation plans for the year ended December 31, 2010, and approximately 98% for each of the years ended December 31, 2009, and 2008.

##### Table of Contents

Restricted Cash. Restricted cash consists of escrow deposits held by lenders for property taxes, insurance and replacement reserves, cash required to be segregated for the repayment of residents’ security deposits, and escrowed amounts related to our development and acquisition activities. Substantially all restricted cash is invested in demand and short-term instruments.
Share-based Compensation. Compensation expense associated with share-based awards is recognized in our consolidated statements of income and comprehensive income using the grant-date fair values. Compensation cost for all share-based awards, including options, requires measurement at estimated fair value on the grant date and recognition of compensation expense over the requisite service period for awards expected to vest. The fair value of stock option grants is estimated using the Black-Scholes valuation model. Valuation models require the input of assumptions, including judgments to estimate the expected stock price volatility, expected life, and forfeiture rate. The compensation cost for share-based awards is based on the market value of the shares on the date of grant.
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 (loss) 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 was approximately 4.8 million, 4.9 million, and 5.2 million for the years ended December 31, 2010, 2009, and 2008, 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
In January 2008, our Board of Trust Managers approved an increase of the April 2007 repurchase plan to allow for the repurchase of up to $500 million of our common equity securities through open market purchases, block purchases, and privately negotiated transactions. Under this program, we have repurchased 4.3 million shares for a total of approximately $230.2 million from April 2007 through December 31, 2010. The remaining dollar value of our common equity securities authorized to be repurchased under the program was approximately $269.8 million as of December 31, 2010. There were no repurchases of our equity securities during the year ended December 31, 2010.
In March 2010, we announced the creation of an at-the-market (“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, in amounts and at times as we determine, into the existing trading market at current market prices as well as through negotiated transactions. 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 year ended December 31, 2010, we issued approximately 4.9 million common shares at an average price of $48.37 per share for total net consideration of approximately $231.7 million. In January 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. As of the date of this filing, we had common shares having an aggregate offering price of up to $10.7 million remaining available for sale under the ATM program.

F-13

##### Table of Contents

We currently have an automatic shelf registration statement on file with the Securities and Exchange Commission 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 million shares of beneficial interest, consisting of 100 million common shares and 10 million preferred shares. As of December 31, 2010, we had approximately 69.6 million common shares outstanding, net of treasury shares and shares held in our deferred compensation arrangements, and no preferred shares outstanding.
5. Operating Partnerships
At December 31, 2010, approximately 12% of our multifamily apartment homes were held in Camden Operating, L.P (“Camden Operating” or the “operating partnership”). Camden Operating has issued both common and preferred limited partnership units. As of December 31, 2010, we held 89.8% of the common limited partnership units and the sole 1% general partnership interest of the operating partnership. The remaining common limited partnership units, comprising approximately 1.1 million units, are primarily held by former officers, directors, and investors of Paragon Group, Inc., which we acquired in 1997. Each common limited partnership unit is redeemable for one common share of Camden or cash at our election. Holders of common limited partnership units are not entitled to rights as shareholders prior to redemption of their common limited partnership units. No member of our management owns Camden Operating common limited partnership units, and two of our ten trust managers own Camden Operating common limited partnership units.
Camden Operating has $100 million of 7.0% Series B Cumulative Redeemable Perpetual Preferred Units outstanding. Distributions on the preferred units are payable quarterly in arrears. The Series B preferred units were redeemable beginning in December 2008 by the operating partnership for cash at par plus the amount of any accumulated and unpaid distributions. There were no redemptions as of December 31, 2010. The preferred units are convertible beginning in 2015 by the holder into a fixed number of corresponding Series B Cumulative Redeemable Perpetual Preferred Shares of Camden. The Series B preferred units are subordinate to present and future debt.
We are the controlling managing member interest in Oasis Martinique, LLC, which owns one property in Orange County, California and is included in our consolidated financial statements. The remaining interests, comprising approximately 0.4 million units, are exchangeable into approximately 0.3 million of our common shares.
At December 31, 2010, approximately 25% of our multifamily apartment homes were held in Camden Summit Partnership, L.P. (the “Camden Summit Partnership”). The Camden Summit Partnership has issued common limited partnership units. As of December 31, 2010, we held 94.0% of the common limited partnership units and the sole 1% general partnership interest of the Camden Summit Partnership. The remaining common limited partnership units, comprising approximately 1.1 million units, are primarily held by former officers, directors, and investors of Summit Properties Inc. (“Summit”), a company we acquired in 2005. Each common limited partnership unit is redeemable for one common share of Camden or cash at our election. Holders of common limited partnership units are not entitled to rights as shareholders prior to redemption of their common limited partnership units. No member of our management owns Camden Summit Partnership common limited partnership units, and two of our ten trust managers own Camden Summit Partnership common limited partnership units.
6. 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 margin taxes. Taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to applicable federal, state, and local income and margin taxes. Our operating partnerships are flow-through entities and are not subject to federal income taxes at the entity level. We have provided for federal, state, and local income, franchise, and margin taxes in the consolidated statements of income and comprehensive income for the years ended December 31, 2010, 2009 and 2008. These taxes are primarily for margin taxes and entity level state income and franchise taxes on certain ventures, and federal taxes on one of our taxable REIT subsidiaries. We have no significant temporary differences or tax credits associated with our taxable REIT subsidiaries.

We have taxable REIT subsidiaries which are subject to federal and state income taxes. At December 31, 2010, our taxable REIT subsidiaries had net operating loss carryforwards (“NOL’s”) of approximately $25.1 million which expire in years 2019 to 2030. Because NOL’s are subject to certain change of ownership, continuity of business, and separate return year limitations, and because it is unlikely the available NOL’s will be utilized or because we consider any amounts possibly utilized to be immaterial, no benefits of these NOL’s have been recognized in our consolidated financial statements.
The carrying value of net assets reported in our consolidated financial statements at December 31, 2010 exceeded the tax basis by approximately $843.9 million.
Income Tax Expense — Current. For the tax years ended December 31, 2010, 2009, and 2008, we had current income tax expense of approximately $1.6 million, $1.0 million, and $0.8 million, respectively. The 2010 tax expense was comprised mainly of entity level state income taxes on certain ventures and federal income tax on one of our taxable REIT subsidiaries. The 2009 and 2008 amounts were comprised mainly of state income taxes.
Income Tax Expense — Deferred. For the years ended December 31, 2010, 2009, and 2008, our deferred tax expense was not significant.

The company and its subsidiaries’ income tax returns are subject to examination by federal, state and local tax jurisdictions for years 2007 through 2009. Net income tax loss carryforwards and other tax attributes generated in years prior to 2007 are also subject to challenge in any examination of those tax years. The company and its subsidiaries are not under any notice of audit from any taxing authority at year end 2010. We believe we have no uncertain tax positions or unrecognized tax benefits requiring disclosure for the periods presented.
7. Property Acquisitions, Discontinued Operations, and Impairments
Acquisitions. During 2010, we acquired three multifamily properties for an aggregate of approximately $63.0 million on behalf of one of our discretionary investment funds (the “Fund”) in which we have a 20% ownership interest. The acquisitions were comprised of 306 units located in Houston, Texas, 110 units located in Atlanta, Georgia and 270 units located in Corpus Christi, Texas.
In August 2010, the ownership of one of our joint ventures, which owns a multifamily property located in Irvine, California, was restructured and resulted in our ownership interest increasing from 30% to 99.99%. We previously accounted for this joint venture in accordance with the equity method of accounting. Following this restructuring, we have consolidated this entity for financial reporting purposes. At the time of this restructuring, we recorded the assets and liabilities of the joint venture at fair value, which resulted in an increase of real estate assets of approximately $92.7 million and a reduction to investments in joint ventures and notes receivable-affiliates of approximately $21.2 million and $20.7 million, respectively. We did not record a gain or loss on this restructuring as the net consideration approximated the fair market value of the net assets received. Subsequent to this restructuring, we repaid the joint venture’s existing $52.1 million secured note, which accrued interest at LIBOR plus 2.25%, and the joint venture entered into a 35 year secured credit agreement with a third-party lender in the amount of $53.0 million with an effective annual interest rate of approximately 4.35%.
In December 2010, the ownership of two of our joint ventures, which own multifamily properties located in Houston, Texas and College Park, Maryland, were restructured and resulted in our ownership interests increasing from 30% to 99.99%. We previously accounted for these joint ventures in accordance with the equity method of accounting. Following this restructuring, we have consolidated these entities for financial reporting purposes. At the time of this restructuring, we recorded the assets and liabilities of the joint ventures at fair value, which resulted in an increase of real estate assets of approximately $146.2 million and a reduction to investments in joint ventures and notes receivable-affiliates of approximately $2.4 million and $14.3 million, respectively. We did not record a gain or loss on this restructuring as the net consideration approximated the fair market value of the net assets received. Subsequent to this restructuring, we repaid one joint venture’s existing $108.8 million secured note, which accrued interest at LIBOR plus 2.0%. Additionally, we assumed the debt of one of the joint venture’s secured notes with third-party lenders for approximately $27.2 million, and repaid one of the secured notes for approximately $4.6 million. The remaining $22.6 million secured note matures in May 2019 and has an effective annual interest rate of 5.33%.
The following is a summary of revenue and earnings, which represents property revenue less property expenses, for the three restructured joint ventures from their respective consolidation dates through December 31, 2010:

Impairment. The impairment associated with land development activities for the years ended December 31, 2009 and 2008 totaled approximately $72.2 million and $50.2 million, respectively, for the difference between the estimated fair value and the carrying value of various land holdings for development projects we either placed on hold or planned to not pursue.
Impairment for the year ended December 31, 2009 included $13.4 million of costs capitalized and exit costs associated with a land development joint venture we placed on hold. In the fourth quarter of 2010, this joint venture was dissolved. Refer to Note 8, “Investments in Joint Ventures,” for further discussion.
During the fourth quarter of 2010, we wrote-off a $1.0 million investment associated with a technology investment which we determined was no longer recoverable.

8. Investments in Joint Ventures
As of December 31, 2010, our equity investments in unconsolidated joint ventures, which we account for utilizing the equity method of accounting, consisted of 20 joint ventures, with our ownership percentages ranging from 15% to 72%. We provide property management services to the majority of these joint ventures which own operating properties and may provide asset management services in addition to 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 December 31 (in millions):

|  | 2010 (2) |  |  | 2009 |
Total assets |  | $ | 935.3 |  |  | $ | 1,202.0 |
Total third-party debt |  |  | 810.1 |  |  |  | 980.9 |
Total equity |  |  | 105.3 |  |  |  | 151.9 |

|  | 2010 |  |  | 2009 |  |  | 2008 |
Total revenues |  | $ | 137.6 |  |  | $ | 137.3 |  |  | $ | 127.1 |
Net income (loss) |  |  | (19.1 | ) |  |  | (18.0 | ) |  |  | (18.7 | )
Equity in income (loss) (1) |  |  | (0.8 | ) |  |  | 0.7 |  |  |  | (1.3 | )

(1) |  | Equity in income (loss) of unconsolidated joint ventures excludes our ownership interest of fee income from various property management services and interest income from mezzanine loans with our joint ventures.
(2) |  | During 2010, we consolidated three joint ventures previously accounted for in accordance with the equity method. Refer to Note 7, “Property Acquisitions, Discontinued Operations and Impairments,” for further discussion of these restructurings.

The joint ventures in which we have an interest have been funded in part with secured third-party debt. We have guaranteed no more than our proportionate interest, totaling approximately $11.0 million, of two loans utilized for construction and development activities for our joint ventures.
Mezzanine loans we have made to affiliated joint ventures are recorded as “Notes receivable — affiliates” and as of December 31, 2010 and 2009, the balance was $3.2 million and $45.8 million, respectively. At December 31, 2010, we had one mezzanine loan outstanding and our commitment to fund additional amounts under this mezzanine loan was approximately $6.0 million.
We may earn fees for property and asset management, construction, development, and other services related primarily to joint ventures in which we own an interest. Fees earned for these services amounted to approximately $8.2 million, $8.0 million, and $9.2 million for the years ended December 31, 2010, 2009, and 2008, respectively. We eliminate fee income from property management services provided to these joint ventures to the extent of our ownership.
On April 15, 2010, a $24.5 million secured third-party construction note made by one of our joint ventures which owns a multifamily property located in Houston, Texas, originally scheduled to mature in April 2010, was contractually extended to April 2011. Concurrent with the construction note extension, our $8.2 million mezzanine loan to this joint venture was converted into an additional $7.2 million common equity interest in the joint venture (with a preference on distribution of cash flows) and $1.0 million common equity interest in the joint venture (without such preference).
In the fourth quarter of 2010, we dissolved a joint venture located in Austin, Texas. In connection with the dissolution, our joint venture partner purchased the third-party debt made by this joint venture from the note holder, which relieved us of our guarantee of our proportionate interest of this debt of approximately $4.2 million; we had previously recorded a charge for this indemnification. Accordingly, we recorded the $4.2 million as other income in our 2010 consolidated statements of income and comprehensive income.
In February 2011, the Fund acquired one multifamily property for approximately $44.5 million. The multifamily property is located in Houston, TX and is comprised of 352 apartment homes.

In August 2010, we entered into a $500 million unsecured credit facility, with the option to increase this credit facility to $600 million, which matures in August 2012 and may be extended at our option to August 2013. This facility replaced our $600 million unsecured credit facility which was scheduled to mature in January 2011. 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 December 31, 2010, we had outstanding letters of credit totaling approximately $10.2 million, leaving approximately $489.8 million available under our unsecured line of credit.
As part of the 2005 Summit merger, we assumed certain debt and recorded approximately $33.9 million as a fair value adjustment which is being amortized over the respective debt terms. As of December 31, 2010, approximately $0.4 million of the fair value adjustment remained unamortized and substantially all of the remaining adjustment will be recorded as an adjustment to interest expense in 2011. We recorded amortization of the fair value adjustment, which resulted in a decrease of interest expense of approximately $1.1 million, $2.3 million, and $5.4 million during the years ended December 31, 2010, 2009, and 2008, respectively.

Subsequent to the restructuring of one of our unconsolidated joint ventures in August 2010, this now fully consolidated joint venture entered into a 35 year secured credit agreement with a third-party lender in the amount of $53.0 million with an effective annual interest rate of approximately 4.35%. Refer to Note 7, “Property Acquisitions, Discontinued Operations, and Impairments,” for further discussion of this transaction.
As part of the joint venture restructurings in December 2010, we assumed the debt of one of the joint venture’s secured notes with a third-party lender for approximately $22.6 million, which matures in May 2019 and has an effective annual interest rate of 5.33%. See Note 7, “Property Acquisitions, Discontinued Operations and Impairments,” for further discussion of these restructurings.
At December 31, 2010 and 2009, the weighted average interest rate on our floating rate debt, which includes our unsecured line of credit, was approximately 1.3% and 1.2%, respectively.
Our indebtedness, including our unsecured line of credit, had a weighted average maturity of approximately 5.5 years at December 31, 2010. Scheduled repayments on outstanding debt, including our line of credit and scheduled principal amortizations, and the weighted average interest rate on maturing debt at December 31, 2010 are as follows:

2016 and thereafter |  |  | 1,149.3 |  |  |  | 4.6 |
Total |  | $ | 2,563.8 |  |  |  | 5.1 | %

The remaining principal amount outstanding on our 7.69% senior unsecured notes matured and was repaid in February 2011 for a total of approximately $88.0 million.
10. 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 an additional $22.6 million will be reclassified to interest expense. 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 years ended December 31, 2010, 2009, and 2008.

##### Table of Contents

As of December 31, 2010, 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.
As of December 31, 2010, 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 |

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. We believe the likelihood of realized losses from counterparty non-performance is remote.
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.
At December 31, 2010, 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 $38.6 million. As of December 31, 2010, we had not posted any collateral related to these agreements. If we were in breach of any of these provisions at December 31, 2010, or terminated these agreements, we would have been required to settle our obligations at their aggregate termination value of approximately $38.6 million.
11. Share-based Compensation and Benefit Plans
Incentive Plan. During 2002, our Board of Trust Managers adopted, and our shareholders approved, the 2002 Share Incentive Plan of Camden Property Trust (the “2002 Share Plan”). Under the 2002 Share Plan, we may issue up to 10% of the total of (i) the number of our common shares outstanding as of the plan date, February 5, 2002, plus (ii) the number of our common shares reserved for issuance upon conversion of securities convertible into or exchangeable for our common shares, plus (iii) the number of our common shares held as treasury shares. Compensation awards eligible to be granted under the 2002 Share Plan include various forms of incentive awards, including incentive share options, non-qualified share options, and share awards. The class of eligible persons which can receive grants of incentive awards under the 2002 Share Plan consists of key employees, consultants, and non-employee trust managers as determined by the Compensation Committee of our Board of Trust Managers. The 2002 Share Plan does not have a termination date; however, no incentive share options will be granted under this plan after February 5, 2012.

Options. Options are exercisable, subject to the terms and conditions of the plan, in increments ranging from 20% to 33.33% per year on each of the anniversaries of the date of grant. The plan provides that the exercise price of an option will be determined by the Compensation Committee of the Board of Trust Managers on the day of grant, and to date all options have been granted at an exercise price that equals the fair market value on the date of grant. Options exercised during 2010 were exercised at prices ranging from $25.88 to $48.02 per option. At December 31, 2010, outstanding options and exercisable options were at prices ranging from $30.06 to $73.32 per option and had a weighted average remaining contractual life of approximately 5.1 years and 3.6 years, respectively.
The total intrinsic value of options exercised was approximately $1.5 million, $0.1 million, and $0.5 million during the years ended December 31, 2010, 2009 and 2008, respectively. As of December 31, 2010, there was approximately $2.3 million of total unrecognized compensation cost related to unvested options, which is expected to be amortized over the next four years.
The following table summarizes share outstanding options and exercisable options at December 31, 2010:

|  | Outstanding Options(1) |  |  | Exercisable Options(1) |
Range of |  |  |  |  |  | Weighted |  |  |  |  |  |  | Weighted |

$42.90-$44.00 |  |  | 508,835 |  |  |  | 43.32 |  |  |  | 452,940 |  |  |  | 43.25 |

Total options |  |  | 1,837,990 |  |  | $ | 42.39 |  |  |  | 1,160,776 |  |  | $ | 45.36 |

(1) |  | The aggregate intrinsic value of outstanding and exercisable options at December 31, 2010 was approximately $22.2 million and $10.9 million, respectively. The aggregate intrinsic values were calculated as the excess, if any, between our closing share price of $53.98 per share on December 31, 2010 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.
The following assumptions were used for options granted during each respective period:

|  | Year Ended |
|  | December 31, |
|  | 2010 |  |  | 2009 |  |  | 2008 |
Weighted average fair value of options granted |  | $ | 11.69 |  |  | $ | 3.06 |  |  | $ | 5.06 |
Expected volatility |  | 35.6% - 39.2% |  |  |  | 33.0 | % |  |  | 20.5 | %
Risk-free interest rate |  | 3.6% - 3.7% |  |  |  | 2.6 | % |  |  | 3.6 | %
Expected dividend yield |  | 4.1% - 4.4% |  |  |  | 9.3 | % |  |  | 5.8 | %
Expected life (in years) |  | 7 - 9 |  |  |  | 7 |  |  |  | 7 |

Our computation of expected volatility for 2010 is based on the historical volatility of our common shares over a time period equal to the expected life of the option and ending on the grant date. The interest rate for periods within the contractual life of the award is based on the U.S. Treasury yield curve in effect at the time of grant. The expected dividend yield on our common shares is estimated using the annual dividends paid in the prior year and the market price on the date of grant. Our computation of expected life for 2010 is estimated based on historical experience of similar awards, giving consideration to the contractual terms of the share-based awards.
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 December 31, 2010, the unamortized value of previously issued unvested share awards was approximately $22.1 million which is expected to be amortized over the next four years. The total fair value of shares vested during the years ended December 31, 2010, 2009, and 2008 was approximately $10.6 million, $10.2 million, and $8.8 million, respectively, and there were a total of 2.4 million vested share awards outstanding at December 31, 2010 with a weighted average issuance price of $38.72. At December 31, 2010, there were approximately 1.3 million share awards and options available for issuance.

Employee Share Purchase Plan (“ESPP”). We have established an ESPP for all active employees and officers who have completed one year of continuous service. Participants may elect to purchase our common shares through payroll deductions and/or through semi-annual contributions. At the end of each six-month offering period, each participant’s account balance is applied to acquire common shares at 85% of the market value, as defined, on the first or last day of the offering period, whichever price is lower. We currently use treasury shares to satisfy ESPP share requirements. Each participant must hold the shares purchased for nine months in order to receive the discount, and a participant may not purchase more than $25,000 in value of shares during any plan year, as defined. The following table presents information related to our ESPP:

|  | 2010 |  |  | 2009 |  |  | 2008 |
Shares purchased |  |  | 29,100 |  |  |  | 34,649 |  |  |  | 25,939 |
Weighted average fair value of shares purchased |  | $ | 50.70 |  |  | $ | 35.68 |  |  | $ | 37.81 |
Expense recorded (in millions) |  | $ | 0.5 |  |  | $ | 0.4 |  |  | $ | 0.1 |

In January 2011, approximately 21,825 shares were purchased under the ESPP related to the 2010 plan year.
Rabbi Trust. We established a rabbi trust for a select group of participants in which share awards granted under the share incentive plan and salary and other cash amounts earned may be deposited. The rabbi trust is an irrevocable trust and no portion of the trust fund may be used for any purpose other than the delivery of those assets to the participants. The assets held in the rabbi trust are subject to the claims of our general creditors in the event of bankruptcy or insolvency. The rabbi trust is in use only for deferrals made prior to 2005, including bonuses related to service in 2004 but paid in 2005.
The value of the assets of the rabbi trust are consolidated into our financial statements based on GAAP. Granted share awards held by the rabbi trust are classified in equity in a manner similar to the manner in which treasury stock is accounted. Subsequent changes in the fair value of the shares are not recognized. The deferred compensation obligation is classified as an equity instrument and changes in the fair value of the amount owed to the participant are not recognized. At December 31, 2010 and 2009, approximately 2.0 million share awards were held in the rabbi trust. Additionally, as of December 31, 2010 and 2009, the rabbi trust held trading securities totaling approximately $53.1 million and $61.7 million, respectively, which represents cash deferrals made by plan participants. Market value fluctuations on these trading securities are recognized in income in accordance with GAAP and the fair value of the liability due to participants is adjusted accordingly.
At December 31, 2010 and 2009, approximately $31.4 million and $34.7 million, respectively, was required to be paid to us by plan participants upon the withdrawal of any assets from the rabbi trust, and is included in “Accounts receivable-affiliates” in our consolidated financial statements.
Non-Qualified Deferred Compensation Plan. The Non-Qualified Deferred Compensation Plan (the “Plan”), effective December 1, 2004, is an unfunded arrangement established and maintained primarily for the benefit of a select group of participants. Eligible participants shall commence participation in the Plan on the date the deferral election first becomes effective. We will credit to the participant’s account an amount equal to the amount designated as the participant’s deferral for the plan year as indicated in the participant’s deferral election(s). Any modification to or termination of the Plan will not reduce a participant’s right to any vested amounts already credited to his or her account. At December 31, 2010 and 2009, approximately 0.7 million and 0.5 million share awards, respectively, were held in the Plan. Additionally, as of December 31, 2010 and 2009, the Plan held trading securities totaling approximately $14.3 million and $12.1 million, respectively, which represents cash deferrals made by plan participants. Market value fluctuations on these trading securities are recognized in income in accordance with GAAP and the fair value of the liability due to participants is adjusted accordingly.
4 01(k) Savings Plan. We have a 401(k) savings plan, which is a voluntary defined contribution plan. Under the savings plan, every employee is eligible to participate, beginning on the date the employee has completed six months of continuous service with us. Each participant may make contributions to the savings plan by means of a pre-tax salary deferral, which may not be less than 1% or more than 60% of the participant’s compensation. The federal tax code limits the annual amount of salary deferrals which may be made by any participant. We may make matching contributions on the participant’s behalf up to a predetermined limit. The matching contribution made for each of the years ended December 31, 2010 and 2009, was approximately $1.3 million, and was approximately $1.4 million for the year ended December 31, 2008. A participant’s salary deferral contribution is 100% vested and nonforfeitable. A participant will become vested in our matching contributions 33% after one year of service, 67% after two years of service and 100% after three years of service. Administrative expenses under the savings plan were paid by us and were not significant for all periods presented.

12. Fair Value Measurements
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 December 31, 2010 and 2009 under the fair value hierarchy discussed above (there was no Level 3 activity during the periods presented):

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 consolidated balance sheets. The balance at December 31, 2010 also reflects approximately $16.3 million of participant withdrawals from our deferred compensation plan investments during 2010.

##### Table of Contents

Available-for-sale Investment. A company in which we had a recorded value of approximately $0.2 million completed an initial public offering during the three months ending September 30, 2010. We have classified this investment as available-for-sale under the Accounting Standards Codification (the “Codification”) and recorded this security as a component of other assets, with any unrealized gains or losses, net of tax, included in accumulated other comprehensive income (loss). The available-for-sale investment is included in Level 1 in the preceding table and is valued using quoted market prices. The following table sets forth the maturity, cost, gross unrealized gains, and fair value of our available-for-sale investment held as of December 31, 2010 (we did not have any available-for-sale investments at December 31, 2009):

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, both 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 by us and our counterparties. However, as of December 31, 2010, 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 December 31, 2010 and 2009, management estimated the carrying value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued expenses and other liabilities, and distributions payable approximated their 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 for the years ended December 31 (in millions):

|  | December 31, 2010 |  |  | December 31, 2009 |
|  | Carrying |  |  | Estimated |  |  | Carrying |  |  | Estimated |
|  | Value |  |  | Fair Value |  |  | Value |  |  | Fair Value |
Notes receivable — affiliates |  | $ | 3.2 |  |  | $ | 3.2 |  |  | $ | 45.8 |  |  | $ | 46.1 |
Fixed rate notes payable (1) |  |  | 2,333.5 |  |  |  | 2,386.0 |  |  |  | 2,396.8 |  |  |  | 2,380.9 |
Floating rate notes payable |  |  | 230.3 |  |  |  | 212.7 |  |  |  | 228.4 |  |  |  | 189.4 |

(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 utilizing level 3 inputs, primarily relate to impairment of long-lived assets or investments, and also consolidation of joint ventures as disclosed at Note 7, “Property Acquisitions, Discontinued Operations and Impairments.”

14. Commitments and Contingencies
Construction Contracts. As of December 31, 2010, we intend to incur approximately $57.2 million of additional expenditures on our construction projects currently under development. We expect to fund these amounts through available cash balances and draws on our unsecured line of credit.
Litigation. We are 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 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 December 31, 2010, we had long-term leases covering certain land, office facilities, and equipment. Rental expense totaled approximately $2.9 million for the year ended December 31, 2010 and totaled approximately $3.0 million for each of the years ended December 31, 2009 and 2008. Minimum annual rental commitments for the years ending December 31, 2011 through 2015 are approximately $2.5 million, $2.1 million, $1.9 million, $1.8 million, and $1.1 million, respectively, and approximately $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.
We have discretionary investment vehicles (the “Funds”) to make direct and indirect investments in multifamily real estate throughout the United States, primarily through acquisitions of operating properties and certain land parcels which will be acquired by or contributed to the Funds for development. The Funds will serve, until the earlier of (i) April 8, 2012, or (ii) such time as 90% of the Funds’ committed capital is invested, as the exclusive vehicles through which we will acquire fully-developed multifamily properties, subject to certain exceptions. These exceptions include properties acquired in tax-deferred transactions, follow-on investments made with respect to prior investments, significant transactions which include the issuance of our securities, significant individual asset and portfolio acquisitions, significant merger and acquisition activities, acquisitions which are inadvisable or inappropriate for the Funds, transactions with our existing ventures, contributions or sales of properties to or entities in which we remain an investor, and transactions approved by the Funds’ advisory board. The Funds will not restrict our development activities and will terminate on April 8, 2018. We are currently targeting acquisitions for the Funds where value creation opportunities are present through one or more of the following: redevelopment activities, market cycle opportunities, or improved property operations. One of our wholly-owned subsidiaries is the general partner of each of the Funds, and we have committed 20% of the total equity of each of the Funds, up to $75 million in the aggregate. We have received commitments to each of the Funds from an unaffiliated investor of $150 million and on December 31, 2008 the Funds were closed to additional investors. Our total capital contributions made to one of the Funds through December 31, 2010 was approximately $10.6 million.
Employment Agreements. At December 31, 2010, we had employment agreements with nine of our senior officers, the terms of which expire at various times through August 20, 2011. Such agreements provide for minimum salary levels, as well as various incentive compensation arrangements, which are payable based on the attainment of specific goals. The agreements also provide for severance payments plus a gross-up payment if certain situations occur, such as termination without cause or a change of control. In the case of six of the agreements, the severance payment equals one times the respective current annual base salary in the case of termination without cause and 2.99 times the respective average annual base salary over the previous three fiscal years in the case of a change of control and a termination of employment or a material adverse change in the scope of their duties. In the case of one agreement, the severance payment equals one times the respective current annual base salary for termination without cause and 2.99 times the greater of current gross income or average gross income over the previous three fiscal years in the case of a change of control. In the case of the other two agreements, the severance payment generally equals 2.99 times the respective average annual compensation over the previous three fiscal years in connection with, among other things, a termination without cause or a change of control, and the officer would be entitled to receive continuation and vesting of certain benefits in the case of such termination.
15. Postretirement Benefits
We maintain a postretirement benefit for two former officers of Summit, who also serve on our Board of Trust Managers. Benefits received by these former employees include medical benefits and office space. Participants in the postretirement plan contribute to the cost of the medical benefits. Our contribution for medical benefits is limited to amounts between $450 and $730 per month per participant and dependents. We contributed approximately $0.2 million for office space during the year ended December 31, 2010 and expect to contribute $0.2 million for office space in 2011. For measurement purposes, an 8.5% rate of increase in the per capita cost of covered health care claims were assumed; the rate was assumed to decrease until 2024 at which point the annual rate would be 4.5% and remain at that level thereafter.

As of December 31, the status of our defined postretirement benefit plan, calculated using generally accepted actuarial principles and procedures, was as follows:

(in thousands) |  | 2010 |  |  | 2009 |
Postretirement benefit obligation, beginning of year |  | $ | 2,949 |  |  | $ | 2,978 |
Interest cost |  |  | 174 |  |  |  | 181 |

Accumulated postretirement benefit obligation, end of year |  | $ | 2,844 |  |  | $ | 2,949 |

(1) |  | Included in other comprehensive income in our Consolidated Statements of Income and Comprehensive Income.

The weighted average discount rate used to determine the value of accumulated postretirement benefit obligation for the years ended December 31, 2010 and 2009 was 6.10% and 6.29%, respectively. As of December 31, 2010, we had accrued for the approximate $2.8 million postretirement liabilities in other liabilities in our consolidated balance sheets.
The benefits expected to be paid in each of the next five fiscal years, and in the aggregate for the five fiscal years thereafter, are as follows:

(in thousands) |  | Estimated Benefit |
Year Beginning January 1 |  | Payment |
2011 |  | $ | 218 |
2012 |  |  | 223 |
2013 |  |  | 228 |
2014 |  |  | 233 |
2015 |  |  | 239 |
2016-2020 |  |  | 1,278 |
Total |  | $ | 2,419 |

The estimated benefit payments are based on assumptions about future events. Actual benefit payments may vary significantly from these estimates.
A 1% increase or decrease in assumed health care cost trend rates has no significant effect on the interest cost component of net periodic postretirement benefit costs. A 1% increase or decrease in assumed health care cost trend rates would increase or decrease the accumulated postretirement benefit obligation by approximately $0.3 million.
16. Noncontrolling Interests
The following table summarizes the effect of changes in our ownership interest in subsidiaries on the equity attributable to us for each of the years ended December 31:
