	1. Description of Business
	Business. Formed on May 25, 1993, Camden Property Trust, a Texas real estate investment trust (“REIT”), is primarily engaged in the ownership, management, development, redevelopment, 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, 2013, we owned interests in, operated, or were developing 184 multifamily properties comprised of 64,328 apartment homes across the United States. Of the 184 properties, 14 properties were under construction, and when completed will consist of a total of 4,354 apartment homes. Additionally, we are adding a subsequent phase to a stabilized community which will consist of 75 apartment homes and we own land holdings we may develop into multifamily apartment communities in the future.

	2. Summary of Significant Accounting Policies
	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 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.
	Acquisitions of Real Estate. Upon acquisition of real estate, we determine the fair value of tangible and intangible assets, which includes land, buildings (as-if-vacant), furniture and fixtures, the value of in-place leases, including above and below market leases, and acquired liabilities. In estimating these values, we apply methods similar to those used by independent appraisers of income-producing property. Upon the acquisition of a controlling interest of an investment in an unconsolidated joint venture, such joint venture is consolidated and our initial equity investment is remeasured to fair value at the date the controlling interest is acquired; any differences between the carrying value of the previously held equity investment is recognized in earnings at the time of obtaining control. Transaction costs associated with the acquisition of operating real estate assets are expensed. Estimates of fair value of acquired debt are based upon interest rates available for the issuance of debt with similar terms and remaining maturities. 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 net carrying value of below market leases is included in other liabilities in our consolidated balance sheets and the net carrying value of in-place leases is included in other assets, net, in our consolidated balance sheets.
	The carrying values of below market leases and in-place leases at December 31, 2013 and 2012 are as follows:
		December 31,
	(in millions)	2013			2012
	Below market leases (Gross carrying value)	$	0.4		$	0.9
	Accumulated amortization	(0.2		)	(0.2		)
	Value of below market leases, net	$	0.2		$	0.7
	In-place leases (Gross carrying value)	$	2.3		$	4.1
	Accumulated amortization	(1.1		)	(1.5		)
	Value of in-place leases, net	$	1.2		$	2.6
	The average amortization period of below market leases and in-place leases for each of the years ended December 31, 2013 and 2012 was approximately six months.
	Revenues recognized related to below market leases and amortization expense related to in-place leases for the years ended December 31, 2013, 2012 and 2011 are as follows:
			December 31,
	(in millions)		2013			2012		2011
	Revenues related to below market leases		$	1.1		$	1.4	$	—
	Amortization of in-place leases		$	5.6		$	13.1	$	3.9
	The unamortized value of the below market leases and in-place leases will be fully amortized during the year ended December 31, 2014.
	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 may exist 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. 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. When impairment exists, the long-lived asset is adjusted to its fair value. In addition, we evaluate our equity investments in joint ventures and if we believe there is an other than temporary decline in market value of our investment below our carrying value, we will record an impairment charge. We did not record any impairment charges for the years ended December 31, 2013, 2012 or 2011.
	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 the judgment and assumptions applied in the impairment analyses, 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 estimates, we may need to take material charges in future periods for impairments related to existing assets. Any such material non-cash charges could 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. 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. We begin capitalizing development, construction, and carrying costs when the development of the future real estate asset is probable and activities necessary to get the underlying real estate ready for its intended use have been initiated. 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 capitalized development 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. Capitalized interest was approximately $15.4 million, $12.5 million, and $8.8 million for the years ended December 31, 2013, 2012, and 2011, respectively. Capitalized real estate taxes were approximately $3.0 million, $2.8 million, and $1.4 million for the years ended December 31, 2013, 2012, and 2011, 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.
	We also incur expenditures related to renovation and construction of office space we lease and we capitalize these leasehold improvements as furniture, fixtures, equipment and other. We depreciate these costs using the straight-line method over the shorter of the lease term or the useful life of the improvement. During the third quarter of 2013, we relocated our corporate headquarters. In conjunction with this relocation, we capitalized approximately $12.2 million related to leasehold improvements which will be depreciated over the life of our new lease.
	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/liabilities (in-place leases and below market leases)	underlying lease term
	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 transaction. 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.
	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 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 satisfied.
	Fair Value. For financial assets and liabilities recorded at fair value on a recurring or non-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.
	In determining fair value, 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.
	Recurring Fair Value Disclosures. The valuation methodology we use to measure our deferred compensation plan investments is based on quoted market prices utilizing public information for the same transactions. Our deferred compensation plan investments are recorded at fair value on a recurring basis and included in other assets in our consolidated balance sheets.
	Non-recurring Fair Value Disclosures. Certain assets are measured at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. These assets primarily include long-lived assets which are recorded at fair value when they are impaired. The fair value methodologies used to measure long-lived assets are described above at "Asset Impairment." The inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy.
	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 interest and fee and asset management income, are recognized as earned. 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 generally 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. We operate in a single reportable segment which includes the ownership, management, development, redevelopment, acquisition, and construction of multifamily apartment communities. Each of our operating properties is considered a separate operating segment as each property earns revenues and incurs expenses, individual operating results are reviewed and discrete financial information is available. We do not distinguish or group our consolidated operations based on geography, size or type. Our multifamily apartment communities have similar economic characteristics and provide similar products and services to our residents. Further, all material operations are within the United States and no multifamily apartment community comprises more than 10% of consolidated revenues. As a result, our operating properties are aggregated into a single reportable segment. Our multifamily communities generate rental revenue and other income through the leasing of apartment homes, which comprised approximately 98% of our total property revenues and total non-property income, excluding income on deferred compensation plans, for each of the years ended December 31, 2013, 2012, and 2011.
	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. These estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances. Future events rarely develop exactly as forecasted, and the best estimates routinely require adjustment.

	3. Share Data
	Basic earnings per share are computed using net income attributable to common shareholders and the weighted average number of common shares outstanding. Diluted earnings per share reflect common shares issuable from the assumed conversion of common share options and share awards granted and units convertible into common shares. Only those items having a dilutive impact on our basic earnings per share are included in diluted earnings per share. Our unvested share-based awards are considered participating securities and are reflected in the calculation of basic and diluted earnings per share using the two-class method. The number of common share equivalent securities excluded from the diluted earnings per share calculation was approximately 2.1 million, 2.3 million, and 4.0 million for the years ended December 31, 2013, 2012, and 2011, 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.

	In May 2012, we created an at-the-market ("ATM") share offering program through which we can, but have no obligation to, sell common shares having an aggregate offering price of up to $300 million (the "2012 ATM program"), 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 by management of the appropriate sources of funding for us. The net proceeds for the year ended December 31, 2013 were used for general corporate purposes, which included funding for development and capital improvement projects.
	The following table presents activity under our 2012 ATM program for the periods presented (in thousands, except per share amounts):
		Year Ended December 31,
		2013		2012
	Total net consideration	$	40,044.10	$	173,607.50
	Common shares sold	555.1		2,607.90
	Average price per share	$	73.73	$	67.63
	As of the date of this filing, we had common shares having an aggregate offering price of up to $82.7 million remaining available for sale under the 2012 ATM program. No additional shares were sold subsequent to December 31, 2013 through the date of this filing.
	In May 2011, we created an ATM share offering program through which we could, but had no obligation to, sell common shares having an aggregate offering price of up to $300 million (the “2011 ATM program”), in amounts and at times as we determined, into the existing trading market at current market prices as well as through negotiated transactions. The net proceeds resulting from the 2011 ATM program were used to redeem all of our outstanding redeemable perpetual preferred units and for other general corporate purposes, which included funding for development activities, financing of acquisitions, repayment of notes payable and borrowings under our $500 million unsecured line of credit. The 2011 ATM program terminated in the second quarter of 2012, and no further common shares are available for sale under the 2011 ATM program.
	In March 2010, we created an ATM share offering program through which we could, but had no obligation to, sell common shares having an aggregate offering price of up to $250 million (the “2010 ATM program”), in amounts and at times as we determined, into the existing trading market at current market prices as well as through negotiated transactions. The 2010 ATM program terminated in the second quarter of 2011, and no further common shares are available for sale under the 2010 ATM program. The net proceeds during 2011 from the 2010 ATM program were used for general corporate purposes.
	The following table presents activity under our 2010 and 2011 ATM programs for the periods presented (in thousands, except per share amounts):
		Year ended December 31,

	Common shares sold	1,971.40		1,751.00
	Average price per share	$	66.01	$	61.95
	We currently have an automatic shelf registration statement which allows us to offer, from time to time, common shares, preferred shares, debt securities, or warrants. Our Amended and Restated Declaration of Trust provides we may issue up to 185 million shares of beneficial interest, consisting of 175 million common shares and 10 million preferred shares. At December 31, 2013, we had approximately 85.3 million common shares outstanding, net of treasury shares and shares held in our deferred compensation arrangements, and no preferred shares outstanding.

	At December 31, 2013, approximately 8% of our multifamily apartment homes were held in Camden Operating, L.P (“Camden Operating” or the “operating partnership”). Camden Operating has 11.9 million outstanding common limited partnership units and as of December 31, 2013, we held 92.1% of the outstanding common limited partnership units and the sole 1% general partnership interest of the operating partnership. The remaining common limited partnership units, comprising approximately 0.8 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 one of our ten trust managers owns Camden Operating common limited partnership units.
	At December 31, 2011, Camden Operating had 4.0 million of 7.0% Series B Cumulative Redeemable Perpetual Preferred Units outstanding. Distributions on the preferred units were payable quarterly in arrears. In February 2012, we redeemed all of these outstanding units at their redemption price of $25.00 per unit, or an aggregate of $100.0 million, plus accrued and unpaid distributions. In connection with this redemption, the unamortized issuance costs relating to these units of approximately $2.1 million were expensed in the first quarter of 2012.
	At December 31, 2013, approximately 26% of our multifamily apartment homes were held in Camden Summit Partnership, L.P. (the “Camden Summit Partnership”). The Camden Summit Partnership has 22.8 million outstanding common limited partnership units and as of December 31, 2013, we held 94.2% of the outstanding 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”), which 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.

	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, margin, and excise 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 income, franchise, and excise taxes in the consolidated statements of income and comprehensive income for the years ended December 31, 2013, 2012 and 2011 as income tax expense. Income taxes for the years ended December 31, 2013, 2012 and 2011, primarily related to state income tax and federal taxes on certain of our taxable REIT subsidiaries. Income taxes for the year ended December 31, 2011 also included approximately $1.0 million associated with the gain recognized on the sale of an available-for-sale investment. We have no significant temporary differences or tax credits associated with our taxable REIT subsidiaries.
	The reconciliation of net income to REIT taxable income is set forth in the following table:

	We have taxable REIT subsidiaries which are subject to federal and state income taxes. At December 31, 2013, our taxable REIT subsidiaries had net operating loss carryforwards (“NOL’s”) of approximately $16.3 million which expire in years 2030 to 2033. Because NOL’s are subject to certain change of ownership, continuity of business, and separate return year limitations, and because we believe it is unlikely the available NOL’s will be utilized or if utilized, any amounts will be immaterial, no benefits related to 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, 2013 exceeded the tax basis by approximately $1.2 billion.
	Income Tax Expense – Current. For the tax years ended December 31, 2013, 2012, and 2011, we had current income tax expense of approximately $1.8 million, $1.2 million, and $2.2 million, respectively. Income tax for the year ended December 31, 2013 and 2012 was comprised mainly of state income tax, and federal income tax related to one of our taxable REIT subsidiaries. Income tax expense for the year ended December 31, 2011 included approximately $1.0 million associated with the gain recognized by one of our taxable REIT subsidiaries on the sale of an available-for-sale investment during 2011, and also is comprised of state income tax, and federal income tax related to another one of our taxable REIT subsidiaries.
	Income Tax Expense – Deferred. For the years ended December 31, 2013, 2012, and 2011, 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 2010 through 2012. Net income tax loss carry forwards and other tax attributes generated in years prior to 2010 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 2013. We believe we have no uncertain tax positions or unrecognized tax benefits requiring disclosure as of and for the periods presented.

	7. Acquisitions and Discontinued Operations
	Acquisitions of operating properties. During the year ended December 31, 2013, we completed the acquisition of three operating properties as follows:
	Acquisitions of Operating Properties		Location		Number of Apartment Homes	Date of Acquisition		Purchase Price
	Camden Post Oak		Houston, TX		356	4/10/13		$108.50
	Camden Sotelo		Tempe, AZ		170	9/11/13		34
	Camden Vantage		Atlanta, GA		592	9/18/13		82.5
	Consolidated total				1,118			$225.00
	During 2012, we acquired seven operating properties comprised of 2,114 units located in Dallas, Texas, Atlanta, Georgia, Ontario, California, Scottsdale, Arizona, and Denver, Colorado for approximately $356.0 million.
	In December 2012, we acquired the remaining 50% ownership interest in an unconsolidated joint venture, Camden Denver West, which owned one apartment community, containing 320 apartment homes located in Denver, Colorado, for approximately $15.9 million and assumed a secured note payable of approximately $26.2 million. As a result of acquiring a controlling interest in the former unconsolidated joint venture, our previously held equity interest was remeasured at fair value, resulting in a gain of approximately $17.2 million. The equity was remeasured utilizing the consideration paid for the acquired 50% ownership interest.
	As of December 31, 2011, we held a 20% ownership interest in twelve unconsolidated joint ventures which owned 12 apartment communities, containing 4,034 apartment homes located in Dallas, Houston, Las Vegas, Phoenix, and Southern California. In January 2012, we acquired the remaining 80% ownership interests in these joint ventures for approximately $99.5 million and assumed approximately $272.6 million in mortgage debt associated with these joint ventures, which was subsequently repaid in January 2012. As a result of acquiring a controlling interest in the former unconsolidated joint ventures, our previously held equity interest was remeasured at fair value, resulting in a gain of approximately $40.2 million. The equity was remeasured utilizing the consideration paid for the acquired 80% ownership interest.
	The following table summarizes the fair values of the assets acquired and liabilities assumed for the acquisition/consolidation of the operating properties described above as of the respective acquisition/consolidation dates (in millions):
			2013			2012
	Assets acquired:
		Buildings and improvements	$	192		$	622.9

		Net assets acquired	$	224.1		$	511.1
	(1) Represents 100% of the fair value of assets of operating properties acquired which includes our previously held investments in the joint ventures acquired in 2012. Upon acquisition, we revalued our investments in these joint ventures which resulted in a fair value adjustment of assets of approximately $42.1 million for the year ended December 31, 2012.
	(2) Mortgage debt assumed in the amount of $272.6 million was subsequently repaid in January 2012 at face value.
	The related assets, liabilities, and results of operations for these acquisitions are included in the consolidated financial statements from the respective dates of acquisition. There was no contingent consideration associated with these acquisitions.
	The operating properties acquired in 2013 as discussed above contributed revenues of approximately $10.8 million and property expenses of approximately $4.5 million from their respective acquisition dates through December 31, 2013. The 13 former joint ventures and seven operating properties acquired in 2012 contributed revenues of approximately $52.8 million and property expenses of approximately $21.0 million from their respective acquisition/consolidation dates through December 31, 2012. Operating properties from three of these former joint ventures acquired in 2012 were sold during the fourth quarter of 2013. The operating properties sold contributed revenues and property expenses of approximately $6.4 million and $3.1 million, respectively, from their respective acquisition dates through December 31, 2012, and is included in income from discontinued operations disclosed below.
	The following unaudited pro forma summary presents consolidated information assuming the acquisitions of the 10 remaining former joint ventures and seven operating properties acquired in 2012, described above had occurred on January 1, 2011. The information below for the year ended December 31, 2012 contains pro forma results for the respective portions of the periods prior to the respective acquisition dates and actual results from the respective acquisition dates through the end of the periods.

	Acquisitions of land. During June 2013, we acquired approximately 38.8 acres in three land parcels located in Scottsdale, Chandler, and Tempe, Arizona for approximately $25.8 million. During the year ended December 31, 2012, we acquired approximately 22.6 acres in four land parcels located in Dallas, Texas, Austin, Texas, Plantation, Florida, and Charlotte, North Carolina for approximately $33.6 million. In January 2014, we acquired approximately 2.9 acres of land located in Houston, Texas for approximately $15.6 million.
	Acquisitions of non-controlling ownership interests. During the year ended December 31, 2012, we purchased the remaining non-controlling ownership interest in three fully consolidated joint ventures, comprised of 680 units located in Houston, Texas and Charlotte, North Carolina, for approximately $16.5 million. The acquisitions of the remaining ownership interest were recorded as equity transactions and, as a result, the carrying balances of the non-controlling interest were eliminated and the remaining difference between the purchase price and carrying balance was recorded as a reduction in additional-paid-in-capital. See Note 15, "Non-controlling interests" for the effect of changes in ownership interests of these joint ventures on the equity attributable to common shareholders.
	Discontinued Operations. For the years ended December 31, 2013, 2012 and 2011, income from discontinued operations included the results of operations of 12 operating properties, comprised of 3,931 apartment homes, sold during 2013. For the years ended December 31, 2012 and 2011, income from discontinued operations also included the results of operations of 11 operating properties, comprised of 3,213 apartment homes, sold during 2012. For the year ended December 31, 2011, income from discontinued operations also included the results of operations of two operating properties, comprised of 788 apartment homes, sold in December 2011.

	8. Investments in Joint Ventures
	Our equity investments in unconsolidated joint ventures, which we account for utilizing the equity method of accounting, consisted of two, four, and 17 joint ventures for the years ended December 31, 2013, 2012 and 2011, respectively. The two joint ventures in which we held an equity investment at December 31, 2013 are two discretionary investment funds (the "funds"), in which we have a 20% ownership. We provide property management services to joint ventures which own operating properties and we may provide construction and development services to the joint ventures which own properties under development. The following table summarizes the combined basis balance sheet and statement of income data for the unconsolidated joint ventures as of and for the periods presented:

	-1	Excludes approximately $20.6 million, $36.0 million, and $30.8 million of revenues for the years ended December 31, 2013, 2012, and 2011, respectively, related to discontinued operations from the sale of 16 operating properties within two of our unconsolidated joint ventures during 2013 and one operating property held for sale within one of our unconsolidated joint ventures at December 31, 2013. Revenues for the years ended December 31, 2012 and 2011 also excludes approximately $23.3 million, and $26.3 million, respectively, related to discontinued operations from the sale of seven operating properties within two of our unconsolidated joint ventures during 2012. Revenues for the year ended December 31, 2011 also excludes approximately $11.4 million related to discontinued operations from the sale of four operating properties within one of our unconsolidated joint ventures during the fourth quarter of 2011.
	-2	Includes approximately $7.8 million and $49.6 million of revenues for the years ended December 31, 2012 and 2011 related to one previously unconsolidated joint venture acquired by us in December 2012 and 12 previously unconsolidated joint ventures acquired by us in January 2012. Refer to Note 7, "Acquisitions and Discontinued Operations" for further discussion of these acquisitions.
	-3	Equity in income excludes our ownership interest of fee income from various property management services provided by us to our joint ventures.
	The funds in which we have a partial interest have been funded in part with secured third-party debt. As of December 31, 2013, we had no outstanding guarantees related to loans of our unconsolidated joint ventures.
	We may earn fees for property and asset management, construction, development, and other services related to joint ventures in which we own an equity interest and also may earn a promoted equity interest if certain thresholds are met. Fees earned for these services were approximately $10.0 million, $11.4 million, and $9.3 million for the years ended December 31, 2013, 2012, and 2011, respectively. We eliminate fee income for services provided to these joint ventures to the extent of our ownership.
	In May 2013, one of our unconsolidated joint ventures sold its 14 operating properties, comprised of 3,098 apartment homes in Las Vegas, Nevada, for approximately $200.2 million. Our proportionate share of the gain was approximately $13.1 million. Additionally, as a result of achieving certain performance measures as set forth in the joint venture agreement, we recognized a promoted equity interest of approximately $5.1 million in 2013. Our proportionate share of the gain and the promoted equity interest were reported as components of equity in income of joint ventures in the consolidated statements of income and comprehensive income.
	In December 2013, one of our funds sold two operating properties comprised of a total of 600 apartment homes for approximately $68.7 million. Our proportionate share of the gains on these transactions was approximately $3.2 million. At December 31, 2013, one of our funds had an operating property held for sale comprised of 240 apartment homes located in San Antonio, Texas. This property sold in February 2014.

	We have a $500 million unsecured credit facility which matures in September 2015 with an option to extend at our election to September 2016. Additionally, we have the option to increase this credit facility to $750 million by either adding additional banks to the credit facility or obtaining the agreement of the existing banks in the credit facility to increase their commitments. The interest rate is based upon LIBOR plus a margin which is 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. We believe we are in compliance with all such financial covenants and limitations.
	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, 2013, we had no balances outstanding on our $500 million unsecured line of credit and we had outstanding letters of credit totaling approximately $11.3 million, leaving approximately $488.7 million available under our unsecured line of credit. As an alternative to our unsecured line of credit, from time to time, we may borrow using an unsecured overnight borrowing facility. Our use of short-term borrowings does not decrease the amount available under our unsecured line of credit. At December 31, 2013, we had no short-term borrowings outstanding.
	In December 2013, we issued from our existing shelf registration statement $250 million aggregate principal amount of 4.25% senior unsecured notes due January 2024 (the “2024 Notes”). The 2024 Notes were offered to the public at 99.814% of their face amount with a yield to maturity of 4.27%. We received net proceeds of approximately $247.4 million, net of underwriting discounts and other offering expenses. Interest on the 2024 Notes is payable semi-annually on July 15 and January 15, beginning July 15, 2014. We may redeem the 2024 Notes, in whole or in part, at any time at a redemption price equal to the principal amount and accrued interest of the notes being redeemed, plus a make-whole provision. If, however, we redeem the 2024 Notes 90 days or fewer prior to the maturity date, the redemption price will equal 100% of the principal amount of the 2024 Notes to be redeemed plus accrued and unpaid interest on the amount being redeemed to the redemption date. The 2024 Notes are direct, senior unsecured obligations and rank equally with all of our other unsecured and unsubordinated indebtedness. We used the proceeds from this offering to pay at maturity the $200 million aggregate principal amount outstanding of our 5.375% Senior Notes due December 15, 2013, plus accrued and unpaid interest to the date of maturity, and the remainder for general corporate purposes, which included property development in the ordinary course of business, capital expenditures and working capital.
	At December 31, 2013 and 2012, the weighted average interest rate on our floating rate debt was approximately 1.0% and 1.1%, respectively.
	Our indebtedness had a weighted average maturity of 6.9 years at December 31, 2013. Scheduled repayments on outstanding debt, including scheduled principal amortizations, and the weighted average interest rate on maturing debt at December 31, 2013 were as follows:

10. Derivative Financial 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. In August 2011, our interest rate swap, with a notional amount of $16.6 million, matured and settled. As a result of the settlement, we did not have any designated hedges as of December 31, 2011. The effective portion of changes in the fair value of derivatives designated and qualifying as cash flow hedges was recorded through settlement in accumulated other comprehensive income and was subsequently reclassified into earnings in the period the hedged forecasted transaction affected earnings. Through August 2011, this derivative was used to hedge the variable cash flows associated with existing variable rate debt.

Non-designated Hedges. Derivatives are not entered into for speculative purposes and are used to manage our exposure to interest rate movements and other identified risks. Our 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 interest and other income (loss).

In connection with the repayment of a $500 million term loan on June 6, 2011, we discontinued the hedging relationship on a $500 million interest rate swap used as a cash flow hedge as of May 31, 2011. Upon repayment of the loan, which eliminated the probable future variable monthly interest payments that were being hedged, we recognized a non-cash charge of approximately $29.8 million which included the accelerated reclassification of amounts previously recorded in accumulated other comprehensive loss related to this swap. Subsequent changes in the market value of the interest rate swap, which matured in October 2012, were recorded directly in earnings in interest and other income (loss).

The tables below present the effect of our derivative financial instruments in the consolidated statements of income and comprehensive income for the years ended December 31 (in millions).

Share-Based Compensation	'
	11. Share-based Compensation and Benefit Plans
	Incentive Compensation. During the second quarter of 2011, our Board of Trust Managers adopted, and on May 11, 2011 our shareholders approved, the 2011 Share Incentive Plan of Camden Property Trust (as amended, the “2011 Share Plan”). Under the 2011 Share Plan, we may issue up to a total of approximately 9.1 million fungible units (the “Fungible Pool Limit”), which is comprised of approximately 5.8 million new fungible units plus approximately 3.3 million fungible units previously available for issuance under our 2002 share incentive plan based on a 3.45 to 1.0 fungible unit to full value award conversion ratio. Fungible units represent the baseline for the number of shares available for issuance under the 2011 Share Plan. Different types of awards are counted differently against the Fungible Pool Limit, as follows:
	•	Each share issued or to be issued in connection with an award, other than an option, right or other award which does not deliver the full value at grant of the underlying shares, will be counted against the Fungible Pool Limit as 3.45 fungible pool units;
	•	Options and other awards which do not deliver the full value at grant of the underlying shares and which expire more than five years from date of grant will be counted against the Fungible Pool Limit as one fungible pool unit; and
	•	Options, rights and other awards which do not deliver the full value at grant and expire five years or less from the date of grant will be counted against the Fungible Pool Limit as 0.83 of a fungible pool unit.
	As of December 31, 2013, approximately 6.7 million fungible units were available under the 2011 Share Plan, which results in approximately 1.9 million common shares which could be granted pursuant to full value awards based on the 3.45 to 1.0 fungible unit to full value award conversion ratio.
	Awards which may be granted under the 2011 Share Plan include incentive share options, non-qualified share options (which may be granted separately or in connection with an option), share awards, dividends and dividend equivalents and other equity based awards. Persons eligible to receive awards under the 2011 Share Plan are trust managers, directors of our affiliates, executive and other officers, key employees and consultants, as determined by the Compensation Committee of our Board of Trust Managers. The 2011 Share Plan will expire on May 11, 2021.
	Options. New 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. Approximately 0.2 million and 0.5 million options were exercised during the years ended December 31, 2013 and 2012, respectively. Options were exercised at prices ranging from $30.06 to $62.32 per option during the year ended December 31, 2013 and at prices ranging from $30.06 to $51.37 per option during the year ended December 31, 2012.
	The total intrinsic value of options exercised was approximately $5.3 million, $12.2 million, and $9.6 million during the years ended December 31, 2013, 2012 and 2011, respectively. At December 31, 2013, there was no unrecognized compensation cost related to remaining unvested options which vest in January, 2014. At December 31, 2013, outstanding options and exercisable options had a weighted average remaining life of approximately 3.2 years and 2.9 years, respectively.
	The following table summarizes outstanding share options and exercisable options at December 31, 2013:
		Outstanding Options (1)						Exercisable Options (1)

	-1	The aggregate intrinsic value of outstanding and exercisable options at December 31, 2013 was approximately $9.8 million and $7.2 million, respectively. The aggregate intrinsic values were calculated as the excess, if any, between our closing share price of $56.88 per share on December 31, 2013 and the strike price of the underlying award.
	Valuation Assumptions. Options generally have a vesting period of three to five years. We estimate the fair values of each option award on the date of grant using the Black-Scholes option pricing model. No new options were granted in 2013, 2012 or 2011.
	Share Awards and Vesting. Share awards generally have a vesting period of three to 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, 2013, the unamortized value of previously issued unvested share awards was approximately $35.7 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, 2013, 2012 and 2011 was approximately $15.9 million, $13.9 million, and $11.5 million, respectively.
	Total compensation cost for option and share awards charged against income was approximately $14.7 million, $13.7 million, and $12.3 million for 2013, 2012 and 2011, respectively. Total capitalized compensation cost for option and share awards was approximately $2.2 million, $1.4 million, and $0.9 million for 2013, 2012 and 2011, respectively.

	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:
		2013				2012			2011
	Shares purchased	17,171				20,137			19,914
	Weighted average fair value of shares purchased	$	62.59			$	67.8		$	63.29
	Expense recorded (in millions)	$	0.2			$	0.3		$	0.3
	In January 2014, approximately 9,167 shares were purchased under the ESPP related to the 2013 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 only in use for deferrals made prior to 2005, including bonuses related to service in 2004 but paid in 2005. 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 value of the assets of the rabbi trust is consolidated into our financial statements. 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, 2013 and 2012, approximately 1.9 million share awards were held in the rabbi trust. Additionally, as of December 31, 2013 and 2012, the rabbi trust held trading securities totaling approximately $41.3 million and $35.7 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 liability due to participants is adjusted accordingly.
	At December 31, 2013 and 2012, approximately $25.4 million and $25.7 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. In 2004, we established a Non-Qualified Deferred Compensation Plan (the “Plan”) which is an unfunded arrangement established and maintained primarily for the benefit of a select group of participants. Eligible participants commence participation in the Plan on the date the deferral election first becomes effective. We 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, 2013 and 2012, approximately 1.2 million and 1.0 million share awards, respectively, were held in the Plan. Additionally, as of December 31, 2013 and 2012, the Plan held trading securities totaling approximately $18.1 million and $15.2 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 liability due to participants is adjusted accordingly.
	In July 2013, we amended and restated the Plan to permit diversification of fully vested share awards into other equity securities subject to a six month holding period, which resulted in the fully vested awards and the proportionate share of nonvested awards eligible for diversification being reclassified from additional paid in capital to temporary equity in our consolidated balance sheets. The share awards are adjusted to their redemption value at each reporting period, with the redemption value based on the market value of the shares at the end of the reporting period. Changes in value from period to period are charged to distributions in excess of net income attributable to common shareholders in our consolidated statements of equity and perpetual preferred units. The following table summarizes the eligible share award activity as recorded in temporary equity from July 31, 2013, the effective date of the amended and restated Plan, through December 31, 2013:
	(in thousands)
	Temporary equity:

	Change in classification of share awards		37,958
	Change in redemption value of share awards		9,575
	Diversification of share awards		(353		)
	Non-qualified deferred compensation share awards at December 31, 2013		$	47,180
	401(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 the years ended December 31, 2013, 2012 and 2011 was approximately $2.2 million, $2.2 million and $1.8 million, respectively. 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.

Financial Instrument Fair Value Disclosures. As of December 31, 2013 and 2012, the carrying values of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and distributions payable represent fair value because of the short-term nature of these instruments. The carrying value of restricted cash approximates its fair value based on the nature of our assessment of the ability to recover these amounts. In calculating the fair value of our notes payable, interest rate and spread assumptions reflect current credit worthiness and market conditions available for the issuance of notes payable with similar terms and remaining maturities. These financial instruments utilize Level 2 inputs.

Commitments and Contingencies Disclosure [Abstract]	'
Commitments And Contingencies	'
	14. Commitments and Contingencies
	Construction Contracts. As of December 31, 2013, we estimate the additional costs to complete 13 consolidated projects currently under construction to be approximately $541.2 million. We expect to fund these amounts through a combination of cash flows generated from operations, draws on our unsecured credit facility or other short-term borrowings, proceeds from property dispositions, the use of debt and equity offerings under our automatic shelf registration statement, equity issued from our ATM programs, other unsecured borrowings and secured mortgages.
	Litigation. One of our wholly-owned subsidiaries previously acted as a general contractor for the construction of an apartment project in Florida which was subsequently sold and converted to condominium units by an unrelated third-party. The condominium association instituted a lawsuit against our subsidiary and other unrelated third-parties in Florida alleging negligent construction and failure to comply with building codes and claimed damages for the costs of repair arising out of the alleged defective construction as well as the recovery of incidental and consequential damages resulting from such alleged negligence. This matter was mediated in December 2013 and the terms of a settlement were agreed upon, subject to the finalization of settlement documentation, pursuant to which we will make a one-time payment to the association in an amount which is not material.
	We are also subject to various legal proceedings and claims which arise in the ordinary course of business. Matters which arise out of allegations of bodily injury, property damage, and employment practices are generally covered by insurance. While the resolution of these legal proceedings and claims cannot be predicted with certainty, management believes the final outcome of such matters will not have a material adverse effect on our 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. At December 31, 2013, we had made earnest money deposits of approximately $2.5 million for potential acquisitions of operating properties and land, of which approximately $2.1 million is non-refundable.
	Lease Commitments. At December 31, 2013, we had long-term leases covering certain land, office facilities and equipment. Rental expense totaled approximately $2.8 million, $2.6 million, and $2.8 million for the years ended December 31, 2013, 2012 and 2011, respectively. Minimum annual rental commitments for the years ending December 31, 2014 through 2018 are approximately $2.8 million, $2.3 million, $2.6 million, $2.7 million, and $2.5 million, respectively, and approximately $15.4 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 land owned directly by the joint venture or partnership. Our decision whether to hold the entire interest in an apartment community or land ourselves, or to have an indirect interest in the community or land 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 investments 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 land or 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.
	Employment Agreements. At December 31, 2013, we had employment agreements with 13 of our senior officers, the terms of which expire at various times through August 20, 2014. 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 10 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.

Summary Of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'
Principles Of Consolidation	'
	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 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	'
	Acquisitions of Real Estate. Upon acquisition of real estate, we determine the fair value of tangible and intangible assets, which includes land, buildings (as-if-vacant), furniture and fixtures, the value of in-place leases, including above and below market leases, and acquired liabilities. In estimating these values, we apply methods similar to those used by independent appraisers of income-producing property. Upon the acquisition of a controlling interest of an investment in an unconsolidated joint venture, such joint venture is consolidated and our initial equity investment is remeasured to fair value at the date the controlling interest is acquired; any differences between the carrying value of the previously held equity investment is recognized in earnings at the time of obtaining control. Transaction costs associated with the acquisition of operating real estate assets are expensed. Estimates of fair value of acquired debt are based upon interest rates available for the issuance of debt with similar terms and remaining maturities. 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 net carrying value of below market leases is included in other liabilities in our consolidated balance sheets and the net carrying value of in-place leases is included in other assets, net, in our consolidated balance sheets.
	The carrying values of below market leases and in-place leases at December 31, 2013 and 2012 are as follows:
		December 31,
	(in millions)	2013			2012
	Below market leases (Gross carrying value)	$	0.4		$	0.9
	Accumulated amortization	(0.2		)	(0.2		)
	Value of below market leases, net	$	0.2		$	0.7
	In-place leases (Gross carrying value)	$	2.3		$	4.1
	Accumulated amortization	(1.1		)	(1.5		)
	Value of in-place leases, net	$	1.2		$	2.6
	The average amortization period of below market leases and in-place leases for each of the years ended December 31, 2013 and 2012 was approximately six months.
	Revenues recognized related to below market leases and amortization expense related to in-place leases for the years ended December 31, 2013, 2012 and 2011 are as follows:
			December 31,
	(in millions)		2013			2012		2011
	Revenues related to below market leases		$	1.1		$	1.4	$	—
	Amortization of in-place leases		$	5.6		$	13.1	$	3.9
	The unamortized value of the below market leases and in-place leases will be fully amortized during the year ended December 31, 2014.
Asset Impairment	'
	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 may exist 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. 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. When impairment exists, the long-lived asset is adjusted to its fair value. In addition, we evaluate our equity investments in joint ventures and if we believe there is an other than temporary decline in market value of our investment below our carrying value, we will record an impairment charge. We did not record any impairment charges for the years ended December 31, 2013, 2012 or 2011.
	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 the judgment and assumptions applied in the impairment analyses, 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 estimates, we may need to take material charges in future periods for impairments related to existing assets. Any such material non-cash charges could have an adverse effect on our consolidated financial position and results of operations.
Cash and Cash Equivalents	'
	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	'
	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. 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. We begin capitalizing development, construction, and carrying costs when the development of the future real estate asset is probable and activities necessary to get the underlying real estate ready for its intended use have been initiated. 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 capitalized development 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. Capitalized interest was approximately $15.4 million, $12.5 million, and $8.8 million for the years ended December 31, 2013, 2012, and 2011, respectively. Capitalized real estate taxes were approximately $3.0 million, $2.8 million, and $1.4 million for the years ended December 31, 2013, 2012, and 2011, 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.
	We also incur expenditures related to renovation and construction of office space we lease and we capitalize these leasehold improvements as furniture, fixtures, equipment and other. We depreciate these costs using the straight-line method over the shorter of the lease term or the useful life of the improvement. During the third quarter of 2013, we relocated our corporate headquarters. In conjunction with this relocation, we capitalized approximately $12.2 million related to leasehold improvements which will be depreciated over the life of our new lease.
	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/liabilities (in-place leases and below market leases)	underlying lease term
Discontinued Operations	'
	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 transaction. 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.
	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 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 satisfied.
Fair Value	'
	Fair Value. For financial assets and liabilities recorded at fair value on a recurring or non-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.
	In determining fair value, 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.
	Recurring Fair Value Disclosures. The valuation methodology we use to measure our deferred compensation plan investments is based on quoted market prices utilizing public information for the same transactions. Our deferred compensation plan investments are recorded at fair value on a recurring basis and included in other assets in our consolidated balance sheets.
	Non-recurring Fair Value Disclosures. Certain assets are measured at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. These assets primarily include long-lived assets which are recorded at fair value when they are impaired. The fair value methodologies used to measure long-lived assets are described above at "Asset Impairment." The inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy.
Income Recognition	'
	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 interest and fee and asset management income, are recognized as earned. 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	'
	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, 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 generally 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	'
	Reportable Segments. We operate in a single reportable segment which includes the ownership, management, development, redevelopment, acquisition, and construction of multifamily apartment communities. Each of our operating properties is considered a separate operating segment as each property earns revenues and incurs expenses, individual operating results are reviewed and discrete financial information is available. We do not distinguish or group our consolidated operations based on geography, size or type. Our multifamily apartment communities have similar economic characteristics and provide similar products and services to our residents. Further, all material operations are within the United States and no multifamily apartment community comprises more than 10% of consolidated revenues. As a result, our operating properties are aggregated into a single reportable segment. Our multifamily communities generate rental revenue and other income through the leasing of apartment homes, which comprised approximately 98% of our total property revenues and total non-property income, excluding income on deferred compensation plans, for each of the years ended December 31, 2013, 2012, and 2011.
Restricted Cash	'
	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	'
	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	'
	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. 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.
