Notes to Condensed Consolidated Financial Statements

(Unaudited)

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 September 30, 2016, we owned interests in, operated, or were developing 158 multifamily properties comprised of 54,925 apartment homes across the United States. Of the 158 properties, seven properties were under construction which will consist of a total of 2,419 apartment homes when completed. We also own land holdings which we may develop into multifamily communities in the future.

2. Summary of Significant Accounting Policies and Recent Accounting Pronouncements

Principles of Consolidation. Our condensed consolidated financial statements include our accounts and the accounts of other subsidiaries and joint ventures (including partnerships and limited liability companies) over which we have control. All intercompany transactions, balances, and profits have been eliminated in consolidation. Investments acquired or created are 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, or non-managing members, to assess whether the limited partners, or non-managing members, hold substantive kick-out or participating rights which indicate we do not have a controlling financial interest. At September 30, 2016, two of our consolidated operating partnerships are VIEs, of which we held between 92% and 94% of the outstanding common limited partnership units and the sole 1% general partnership interest of each consolidated operating partnership. As we are considered the primary beneficiary, we would continue to consolidate these operating partnerships.

Interim Financial Reporting. We have prepared these unaudited financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial statements and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, these statements do not include all information and footnote disclosures required for annual statements. While we believe the disclosures presented are adequate for interim reporting, these interim unaudited financial statements should be read in conjunction with the audited financial statements and notes included in our 2015 Annual Report on Form 10-K. Certain insignificant amounts in the unaudited condensed consolidated statements of cash flows for the nine months ended September 30, 2015 have been reclassified to conform to the current year presentation. These reclassifications had no impact on our condensed consolidated cash flows from operating, investing or financing activities. As a result of our adoption of Accounting Standards Update 2015-03 ("ASU 2015-03"),  "Simplifying the Presentation of Debt Issuance Costs," as supplemented by Accounting Standards Update 2015-15 ("ASU 2015-15"), "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements," as of December 31, 2015, we reclassified $0.3 million and $0.9 million of deferred financing charges relating to our unsecured credit facility to depreciation and amortization in our condensed consolidated statements of income and comprehensive income for the three and nine months ended September 30, 2015, respectively. We also reclassified $0.4 million and $1.3 million of deferred charges for the three and nine months ended September 30, 2015, respectively, to interest expense. In the opinion of management, all adjustments and eliminations, consisting of normal recurring adjustments, necessary for a fair representation of our financial statements for the interim period reported have been included. Operating results for the three and nine months ended September 30, 2016 are not necessarily indicative of the results which may be expected for the full year.

Asset Impairment. Long-lived assets are reviewed for impairment annually or whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Impairment 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, but not limited to, 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 utilize 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

9

below our carrying value, we will record an impairment charge. We did not record any impairment charges for the three and nine months ended September 30, 2016 or 2015.

The value of our properties under development depends on market conditions, including, but not limited to, 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.

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 certain activities necessary to prepare the underlying real estate 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 $4.5 million and $4.3 million for the three months ended September 30, 2016 and 2015, respectively, and was approximately $13.8 million and $14.9 million for the nine months ended September 30, 2016 and 2015, respectively. Capitalized real estate taxes were approximately $0.6 million and 0.9 million for the three months ended September 30, 2016 and 2015, respectively, and were approximately $3.3 million and $2.9 million for the nine months ended September 30, 2016 and 2015, respectively.

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 above and below market leases)	underlying lease term

Discontinued Operations. A property is classified as a discontinued operation when the disposal represents a strategic shift, such as disposal of a major line of business, a major geographical area or a major equity investment. The results of operations for properties sold or classified as held for sale at the end of the period, and meeting the above criteria of discontinued operations, are classified as discontinued operations for all periods presented. 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 meeting the criteria of discontinued operations 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 condensed consolidated balance sheets for all periods presented. Subsequent to classification of a property as held for sale, no further depreciation is recorded. Properties sold by our unconsolidated entities which do not meet the above criteria of discontinued operations are not included in discontinued operations and related gains or losses are reported as a component of equity in income of joint ventures.

10

Gains on sale of real estate are recognized using the full accrual or partial sale methods, as applicable, in accordance with GAAP, provided various criteria relating to the terms of sale and any subsequent involvement with the real estate sold are satisfied.

See Note 5, "Acquisitions, Dispositions and Discontinued Operations and Assets Held for Sale," for a discussion of discontinued operations for the three and nine months ended September 30, 2016 and 2015.

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 expect to receive to sell an asset, or pay to transfer a liability, in an orderly transaction with a market participant at the measurement date under current market conditions. 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 Measurements. 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 condensed consolidated balance sheets. The inputs associated with the valuation of our recurring deferred compensation plan investments are included in Level 1 of the fair value hierarchy.

Non-Recurring Fair Value Measurements. 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 if they are impaired using the fair value methodologies used to measure long-lived assets described above at "Asset Impairment." Non-recurring fair value disclosures are not provided for impairments on assets disposed during the period because they are no longer owned by us. The inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy, unless a quoted price for a similar long-lived asset in an active market exists, at which time they are included in Level 2 of the fair value hierarchy.

Financial Instrument Fair Value Disclosures. As of September 30, 2016 and December 31, 2015, the carrying values of cash and cash equivalents, short-term investments, 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. The carrying values of our notes receivable also approximate their fair values, which are based on certain factors, such as market interest rates, terms of the note and credit worthiness of the borrower. These financial instruments utilize Level 3 inputs. 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.

Notes Receivable. Our notes receivable, which are included in other assets, net, in our condensed consolidated balance sheets, relate to real estate secured loans to unaffiliated third parties. At September 30, 2016 and December 31, 2015, we had outstanding notes receivable balances of approximately $19.9 million and $13.2 million, respectively, and the weighted average interest rate on such notes was approximately 4.1% for each of the nine months ended September 30, 2016 and 2015. At September 30, 2016, we were also committed to funding additional amounts under one of the loans in the amount of approximately $1.5 million. Interest is recognized over the lives of the notes and is included in interest and other income in our consolidated statements of income and comprehensive income. We consider a note receivable to be impaired if it is probable we will not collect all contractually due principal and interest. We do not accrue interest when a note is considered impaired and an allowance is recorded for any principal and previously accrued interest which is not believed to be collectible.

11

Short-term Investments. At September 30, 2016, our short-term investments consists of certificates of deposit which have maturities of more than three months but less than one year.  The carrying value of our short-term investments approximate their fair values due to the short-term nature of these investments.

Recent Accounting Pronouncements. In January 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2016-01 ("ASU 2016-01"), "Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01 changes certain recognition, measurement, presentation, and disclosure requirements for financial instruments. This standard requires all equity investments, except those accounted for under the equity method of accounting or resulting in consolidation, to be measured at fair value with changes in fair value recognized in net income. This standard also simplifies the impairment assessment for equity investments without readily determinable fair values, amends the presentation requirements for changes in the fair value of financial liabilities, requires presentation of financial instruments by measurement category and form of financial asset, and eliminates the requirement to disclose the methods and significant assumptions used in estimating the fair value of financial instruments. ASU 2016-01 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is not permitted except for the amended presentation requirements for changes in the fair value of financial liabilities. We expect to adopt ASU 2016-01 as of January 1, 2018, and do not expect it to have a material impact on our consolidated financial statements upon adoption.

In February 2016, the FASB issued Accounting Standards Update 2016-02 ("ASU 2016-02"), "Leases." ASU 2016-02 requires lessees to recognize right-of-use assets and lease liabilities on the balance sheet for all leases of property, plant and equipment with lease terms greater than 12 months. Prior to this accounting standard, only capital leases were recognized on the balance sheet. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. This standard must be applied as of the beginning of the earliest comparative period presented in the year of adoption. We expect to adopt ASU 2016-02 as of January 1, 2019. We are currently evaluating the impact this standard may have on our consolidated financial statements upon adoption in conjunction with Accounting Standards Update 2014-09 ("ASU 2014-09"), "Revenue from Contracts with Customers" discussed below.

In May 2014, the FASB issued ASU 2014-09, which provides a single comprehensive revenue recognition model for contracts with customers (excluding certain contracts, such as lease contracts) to improve comparability within industries. ASU 2014-09 requires an entity to recognize revenue to reflect the transfer of goods or services to customers at an amount the entity expects to be paid in exchange for those goods and services and provide enhanced disclosures, all to provide more comprehensive guidance for transactions such as service revenue and contract modifications. In August 2015, the FASB deferred the effective date of ASU 2014-09 by one year, and it is now effective for interim and annual periods beginning after December 15, 2017. In March 2016, the FASB issued Accounting Standards Update 2016-08 ("ASU 2016-08"), "Principal versus Agent Considerations (Reporting Revenue Gross versus Net)." ASU 2016-08 amends ASU 2014-09 to assist in the decision of whether an entity is a principal or agent in a revenue transaction in which a third party is involved in providing goods or services to a customer of the entity. Early adoption of ASU 2014-09 is permitted but not before the original effective date, which applied to interim and annual periods beginning after December 15, 2016. ASU 2014-09 may be applied using either a full retrospective or a modified approach upon adoption. We expect to adopt this standard as of January 1, 2018, and we are currently evaluating the impact this standard may have on our consolidated financial statements upon adoption in conjunction with ASU 2016-02.

In March 2016, the FASB issued ASU 2016-07, "Simplifying the Transition to the Equity Method of Accounting." ASU 2016-07 eliminates the requirement to retroactively adjust an investment when the investment qualifies for use of the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence. Additionally, if the investment was previously accounted for as an available-for-sale security, any unrealized holding gain or loss in accumulated other comprehensive income would be recognized in earnings at the date the investment qualifies for the equity method of accounting. ASU 2016-07 is effective for interim and annual periods beginning after December 15, 2016, and early adoption is permitted. This standard must be applied prospectively. We expect to adopt ASU 2016-07 as of January 1, 2017, and do not expect it to have a material impact on our consolidated financial statements upon adoption.

In March 2016, the FASB issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 amends several aspects of the accounting for share-based payment transactions, including the income tax consequences, accrual of compensation cost, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016, and early adoption is permitted. The amendments in this standard must be applied prospectively, retrospectively, or as of the beginning of the earliest comparative period presented in the year of adoption, depending on the type of amendment. We expect to adopt ASU 2016-09 as of January 1, 2017, and we do not expect it to have a material impact on our consolidated financial statements upon adoption.

12

In August 2016, the FASB issued Accounting Standards Update 2016-15 ("ASU 2016-15"), "Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)." ASU 2016-15 clarifies how several specific cash receipts and cash payments are to be presented and classified on the statement of cash flows, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration made after a business combination, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of predominance principle. ASU 2016-15 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted. Each amendment in this standard must be applied prospectively, retrospectively, or as of the beginning of the earliest comparative period presented in the year of adoption, depending on the type of amendment. We expect to adopt ASU 2016-15 as of January 1, 2018, and we are currently evaluating the impact this standard may have on our consolidated financial statements upon adoption.

3. Per Share Data

Basic earnings per share is computed using net income attributable to common shareholders and the weighted average number of common shares outstanding. Diluted earnings per share reflects 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 2.4 million and 2.6 million for the three months ended September 30, 2016 and 2015, respectively, and was approximately 2.5 million and 2.6 million for the nine months ended September 30, 2016 and 2015, 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 calculations as they are anti-dilutive.

The following table presents information necessary to calculate basic and diluted earnings per share for the periods indicated:

4. Common Shares

In November 2014, we created an ATM share offering program through which we can, but have no obligation to, sell common shares having an aggregate offering price of up to $331.3 million, with $315.3 million remaining available for sale as of the date of this filing. There were no shares sold during the nine months ended September 30, 2016 or 2015, and no shares have been sold through the date of this filing.

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 repurchased 4.3 million shares for a total of approximately $230.2 million from April 2007 through December 31, 2008 and there have not been any shares repurchased subsequent to that date. As of the date of this filing, the remaining dollar value of our common equity securities authorized to be repurchased under the program was approximately $269.8 million.

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 millionpreferred shares. At September 30, 2016, we had approximately87.5 million common shares outstanding, net of treasury shares and shares held in our deferred compensation arrangements, and no preferred shares outstanding.

In September 2016, our Board of Trust Managers declared a quarterly dividend of $0.75 per common share to our shareholders of record as of September 30, 2016. The quarterly dividend was paid on October 17, 2016. We paid equivalent amounts per unit to holders of the common unit partnerships.

In addition to our quarterly dividend, our Board of Trust Managers declared a special dividend of $4.25 per common share to our common shareholders of record as of September 23, 2016, consisting primarily of gains on dispositions completed in 2016. The special dividend was paid on September 30, 2016. We also paid equivalent amounts per unit to holders of the common operating partnership units.

5. Acquisitions, Dispositions and Discontinued Operations and Assets Held for Sale

Acquisitions of Land. In September 2016, we acquired approximately 2.4 acres of land in Denver, Colorado for $15.0 million. This acquisition was funded with cash on hand and from the use of $13.0 million which we had placed with a qualified intermediary in the second quarter of 2016 in connection with a like-kind exchange related to the sale of one of the Las Vegas properties discussed below. In 2016, we also acquired approximately 2.2 acres of land in Charlotte, North Carolina for approximately $4.9 million.

In 2015, we acquired approximately 49.6 acres of land located in Phoenix, Arizona and approximately 2.7 acres of land located in Los Angeles, California for an aggregate of approximately $45.8 million.

Sale of Operating Properties. During the three months ended September 30, 2016, we sold one dual-phased operating property and five other operating properties comprised of an aggregate of 2,906 apartment homes located in Landover and Frederick, Maryland, Fullerton, California, and Tampa, Altamonte Springs, and St. Petersburg, Florida for an aggregate of approximately $484.4 million, and recognized a gain of approximately $262.7 million. In June 2016, we sold one operating property comprised of 278 apartment homes located in Tampa, Florida for approximately $39.0 million, and recognized a gain of approximately $32.2 million.

In January 2015, we sold two operating properties, comprised of an aggregate of 1,116 apartment homes located in Tampa, Florida and Austin, Texas for an aggregate of approximately $114.4 million and we recognized a gain of approximately $85.1 million relating to these property sales.

Land Holding Dispositions. In February 2016, we sold approximately6.3acres of land adjacent to an operating property in Tampa, Florida for approximately$2.2 millionand recognized a gain of approximately$0.4 million. In March 2015, we sold a land holding adjacent to an operating property in Dallas, Texas for approximately $0.4 million and recognized a gain of approximately $0.1 million.

Discontinued Operations and Assets Held for Sale. In April 2016, we sold 15 operating properties, comprised of an aggregate of 4,918 apartment homes, with an average age of 23 years, a retail center and approximately 19.6 acres of land, all located in Las Vegas, Nevada, to an unaffiliated third party for an aggregate of approximately $630.0 million and recognized a gain of approximately $375.2 million. We placed $13.0 million of the proceeds from this disposition with a qualified intermediary for use in a like-kind exchange, which was classified as restricted cash at June 30, 2016. In September 2016, the exchange was successfully completed and the proceeds were released from escrow.

The operating properties, retail center, and land discussed above were classified as held for sale in the condensed consolidated balance sheet at December 31, 2015, and were made up of the following:

(in thousands)	December 31, 2015
Land	$	59,438

6. Investments in Joint Ventures

As of September 30, 2016, our equity investments in unconsolidated joint ventures, which we account for utilizing the equity method of accounting, consisted of three discretionary investment funds (collectively, the "Funds"), with our ownership percentages ranging from 20% to 31.3%. One of the Funds, in which we have a 20% ownership interest, did not own any properties for any periods presented. We provide property and asset management and other services to the Funds which own operating properties and we may also provide construction and development services to the Funds which own properties under development. The following table summarizes the combined balance sheet and statement of income data for the Funds as of and for the periods presented:

(in millions)	September 30, 2016		December 31, 2015
Total assets	$	729.3	$	748.0
Total third-party debt	521.0		527.0
Total equity	183.5		195.3

	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2016		2015		2016		2015
Total revenues	$	30.5	$	29.4	$	89.9	$	85.2
Net income	3.9		3.1		10.2		8.7
Equity in income (1)	1.9		1.6		5.1		4.5

(1) Equity in income excludes our ownership interest of fee income from various services provided by us to the Funds.

The Funds have been funded in part with secured third-party debt and, as of September 30, 2016, we had no outstanding guarantees related to debt of the Funds.

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 may earn a promoted equity interest if certain thresholds are met. We eliminate fee income for services provided to these joint ventures to the extent of our ownership. Fees earned for these services, net of eliminations, were approximately $1.3 million and $1.4 million for the three months ended September 30, 2016 and 2015, respectively, and were approximately $4.0 million and $4.4 million for the nine months ended September 30, 2016 and 2015, respectively.

(1) Unamortized debt discounts and debt issuance costs of $16.4 million and $18.6 million are included in senior unsecured and secured notes payable as of September 30, 2016 and December 31, 2015, respectively.

We have a $600 millionunsecured credit facility which matures inAugust 2019, with two six-month options to extend the maturity date at our election to August 2020. Additionally, we have the option to further increase our credit facility to $900 millionby either adding additional banks to the facility or obtaining the agreement of the existing banks to increase their commitments. The interest rate on our credit facility is based upon the London Interbank Offered Rate ("LIBOR") plus a margin which is subject to change as our credit ratings change. Advances under our credit facility 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$300 millionor the remaining amount available under our credit facility. Our credit facility is subject to customary financial covenants and limitations. We believe we are in compliance with all such financial covenants and limitations on the date of this filing.

Our credit facility provides us with the ability to issue up to $50 million in letters of credit. While our issuance of letters of credit does not increase our borrowings outstanding under our credit facility, it does reduce the amount available. At September 30, 2016, we had no balances outstanding on our $600 millioncredit facility and we had outstanding letters of credit totaling approximately$13.3 million, leaving approximately $586.7 millionavailable under our credit facility.

At September 30, 2016 and 2015, we had outstanding floating rate debt of approximately $206.1 million and $431.0 million, respectively, which also included our unsecured credit facility and unsecured short-term borrowings at September 30, 2015. The weighted average interest rate on such debt was approximately 1.4% and 1.0% for the nine months ended September 30, 2016 and 2015, respectively.

17

Our indebtedness had a weighted average maturity of approximately 5.1 years at September 30, 2016. The table below is a summary of the maturity dates of our outstanding debt and principal amortizations, and the weighted average interest rates on such debt, at September 30, 2016:

(in millions)	Amount		Weighted Average  Interest Rate

8. Share-based Compensation and Non-Qualified Deferred Compensation Plan

Incentive Compensation. During the second quarter of 2011, our Board of Trust Managers adopted, and 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.

At September 30, 2016, approximately 3.7 million fungible units were available under the 2011 Share Plan, which results in approximately 1.1 million common shares which may 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 2011 Share Plan, in increments ranging from 20% to 33.33% per year on each of the anniversaries of the date of grant. The 2011 Share 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 0.1 million options were exercised during the nine months ended September 30, 2016 and 2015, respectively. The total intrinsic value of options exercised was approximately $8.9 million and $2.0 million during the nine months ended September 30, 2016 and 2015, respectively. At September 30, 2016, there was no unrecognized compensation cost related to unvested options. At September 30, 2016, all options outstanding were exercisable and had a weighted average remaining life of approximately 2.2 years.

18

The following table summarizes outstanding share options, all of which were exercisable, at September 30, 2016:

	Options Outstanding and Exercisable (1)
Exercise Prices	Number	Weighted Average Price
$30.06	65,460
$75.17	26,752
$85.05	12,854
Total options	105,066	$	48.27

(1) The aggregate intrinsic value of options outstanding and exercisable at September 30, 2016 was $3.7 million. The aggregate intrinsic value was calculated as the excess, if any, between our closing share price of $83.74 per share on September 30, 2016 and the strike price of the underlying award.

Options Granted and Valuation Assumptions. During the nine months ended September 30, 2016, we granted approximately 13 thousand reload options. Reload options are granted for the number of shares tendered as payment for the exercise price upon the exercise of an option with a reload provision. The reload options granted have an exercise price equal to the fair market value of a common share on the date of grant and expire on the same date as the original options which were exercised. The reload options granted during the nine months ended September 30, 2016 vested immediately and approximately $0.1 million was expensed on the reload date. We estimate the fair values of each option award including reloads on the date of grant using the Black-Scholes option pricing model. The following assumptions were used for the reload options granted during the nine months ended September 30, 2016:

	Nine Months Ended September 30, 2016
Weighted average fair value of options granted	$6.71
Expected volatility	18.0%
Risk-free interest rate	0.9%
Expected dividend yield	3.8%
Expected life	3 years

Our computation of expected volatility for 2016 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, and 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 based on the historical dividend yield over the expected term of the options granted. Our computation of expected life is based upon historical experience of similar awards, giving consideration to the contractual terms of the share-based awards.

Share Awards and Vesting. Share awards for employees generally have a vesting period of three to five years. The compensation cost for share awards is generally based on the market value of the shares on the date of grant and is amortized over the vesting period. In the event the holder of the share awards will reach both the retirement eligibility age of 65 years and the service requirements as defined in the 2011 Share Plan before the term in which the awards are scheduled to vest, the value of the share awards is amortized from the date of grant to the individual's retirement eligibility date. To estimate forfeitures, we use actual forfeiture history. At September 30, 2016, the unamortized value of previously issued unvested share awards was approximately $31.9 million, which is expected to be amortized over the next two years. The total fair value of shares vested during the nine months ended September 30, 2016 and 2015 was approximately $22.6 million and $18.1 million, respectively.

Total compensation cost for option and share awards charged against income was approximately $5.4 million and $4.8 million for the three months ended September 30, 2016 and 2015, respectively, and approximately $16.3 million and $13.7 million for the nine months ended September 30, 2016 and 2015, respectively. Total capitalized compensation cost for option and share awards was approximately $1.0 million and $0.9 million for the three months ended September 30, 2016 and 2015, respectively, and approximately $2.8 million and $2.6 million for the nine months ended September 30, 2016 and 2015, respectively.

The following table summarizes activity under our share incentive plans for the nine months ended September 30, 2016:

10. Commitments and Contingencies

Construction Contracts. As of September 30, 2016, we estimate the total additional cost to complete the seven consolidated projects currently under construction to be approximately $212.6 million. We expect to fund this amount through a combination of one or more of the following: cash and cash equivalents, short-term investments, cash flows generated from operations, draws on our unsecured credit facility, proceeds from property dispositions, the use of debt and equity offerings under our automatic shelf registration statement, equity issued from our ATM program, other unsecured borrowings and secured mortgages.

20

Other Commitments and 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 September 30, 2016, we had no earnest money deposits for potential acquisitions of land which are included in other assets, net in our condensed consolidated balance sheets.

Lease Commitments. At September 30, 2016, we had long-term leases covering certain land, office facilities, and equipment. Rental expense totaled approximately $1.0 million and $0.8 million for the three months ended September 30, 2016 and 2015, respectively, and approximately $3.1 million and $2.4 million for the nine months ended September 30, 2016 and 2015, respectively. Minimum annual rental commitments for the remainder of 2016 are $0.7 million, and for the years ending December 31, 2017 through 2020 are approximately $2.9 million, $2.7 million, $2.5 million, and $2.5 million, respectively, and approximately $11.1 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 or dispose of land or of a community in our sole discretion may be limited to varying degrees in our existing joint venture agreements and may be limited to varying degrees depending on the terms of future joint venture agreements.

11. Income Taxes

We have maintained and intend to maintain our election as a REIT under the Internal Revenue Code of 1986, as amended. In order for us to continue to qualify as a REIT we must meet a number of organizational and operational requirements, including a requirement to distribute annual dividends to our shareholders equal to a minimum of 90% of our adjusted taxable income. As a REIT, we generally will not be subject to federal income tax on our taxable income at the corporate level to the extent such income is distributed to our shareholders annually. If our taxable income exceeds our dividends in a tax year, REIT tax rules allow us to designate dividends from the subsequent tax year in order to avoid current taxation on undistributed income. If we fail to qualify as a REIT in any taxable year, we will be subject to federal and state income taxes at regular corporate rates, including any applicable alternative minimum tax. In addition, we may not be able to requalify as a REIT for the four subsequent taxable years. Historically, we have incurred only state and local income, franchise, and excise taxes. Taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to applicable federal, state, and local income taxes. Our consolidated operating partnerships are flow-through entities and are not subject to federal income taxes at the entity level.

We have recorded income, franchise, and excise taxes in the condensed consolidated statements of income and comprehensive income for the three and nine months ended September 30, 2016 and 2015 as income tax expense. Income taxes for the three and nine months ended September 30, 2016 primarily related to state income tax and federal taxes on certain of our taxable REIT subsidiaries. We have no significant temporary or permanent differences or tax credits associated with our taxable REIT subsidiaries.

We believe we have no uncertain tax positions or unrecognized tax benefits requiring disclosure as of and for the nine months ended September 30, 2016.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the condensed consolidated financial statements and notes appearing elsewhere in this report, as well as Part I, Item 1A, "Risk Factors" within our Annual Report on Form 10-K for the year ended December 31, 2015. Historical results and trends which might appear in the condensed 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.

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 these statements 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 which 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, either nationally or regionally in one or more of the markets in which we operate, could adversely impact us;

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

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

• We face risks associated with land holdings and related activities;

• Potential reforms to Fannie Mae and Freddie Mac could adversely affect us;

• Development, redevelopment and construction risks could impact our profitability;

• Investments through joint ventures and discretionary funds involve risks not present in investments in which we are the sole investor;

• Competition could adversely affect our ability to acquire properties;

• Our acquisition strategy may not produce the cash flows expected;

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

• Litigation risks could affect our business;

• Losses from catastrophes may exceed our insurance coverage;

• A cybersecurity incident and other technology disruptions could negatively impact our business;

• We have significant debt, which could have adverse consequences;

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

• Issuances of additional debt may adversely impact our financial condition;

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

• Variable rate debt is subject to interest rate risk;

• 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 amount of dividend distributions in future periods may vary and be impacted by economic and 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, redevelopment, acquisition, and construction of multifamily apartment communities. As of September 30, 2016, we owned interests in, operated, or were developing 158 multifamily properties comprised of 54,925 apartment homes across the United States. In addition, we own other land holdings which we may develop into multifamily apartment communities in the future.

Property Operations

Our results for each of the three and nine months ended September 30, 2016 reflect an increase in same store revenues of 3.7% and 4.2%, respectively, as compared to the same periods in 2015, due to higher average rental rates and increased other property income, which we believe were due to, among other matters, the continuation of improving economic conditions including job growth, favorable demographics, a manageable supply of new multifamily housing, and more individuals choosing to rent versus buy as evidenced by the moderating level of homeownership rates across the U.S. We believe U.S. economic and employment growth is likely to continue during the remainder of 2016 and the supply of new multifamily homes, although increasing, will likely remain at manageable levels. If economic conditions were to worsen, our operating results could be adversely affected.

Construction Activity

At September 30, 2016, we had seven projects under construction to be comprised of 2,419 apartment homes, with initial occupancy scheduled to occur within the next 21 months. As of September 30, 2016, we estimate the total additional cost to complete the construction of the seven projects to be approximately $212.6 million.

Acquisitions

In September 2016, we acquired approximately 2.4 acres of land in Denver, Colorado for $15.0 million. In 2016, we also acquired approximately 2.2 acres of land in Charlotte, North Carolina for approximately $4.9 million.

Dispositions

Operating properties: During the three months ended September 30, 2016, we sold one dual-phased property and five other operating properties comprised of an aggregate of 2,906 apartment homes located in Landover and Frederick, Maryland, Fullerton, California, and Tampa, Altamonte Springs, and St. Petersburg, Florida for an aggregate of approximately $484.4 million, and recognized a gain of approximately $262.7 million. In June 2016, we sold one operating property comprised of 278 apartment homes located in Tampa, Florida for approximately $39.0 million, and recognized a gain of approximately $32.2 million.

Land: In February 2016, we sold approximately6.3acres of land adjacent to an operating property in Tampa, Florida for approximately$2.2 millionand recognized a gain of approximately$0.4 million.

Discontinued operations: In April 2016, we sold 15 operating properties, comprised of an aggregate of 4,918 apartment homes, with an average age of 23 years, a retail center and approximately 19.6 acres of land, all located in Las Vegas, Nevada, to an unaffiliated third party for an aggregate of approximately $630.0 million and recognized a gain of approximately $375.2 million.

Future Outlook

Subject to market conditions, we intend to continue to seek opportunities to develop, redevelop and acquire existing communities. We also intend to evaluate our operating property and land development portfolio and plan to continue our practice of selective dispositions as market conditions warrant and opportunities arise.We expect to strengthen our capital and liquidity positions by continuing to focus on our core fundamentals which we believe are generating positive cash flows from operations, maintaining appropriate debt levels and leverage ratios, and controlling overhead costs. We intend to meet our near-term liquidity requirements through a combination of one or more of the following: cash and cash equivalents, short-term investments, cash flows generated from operations, draws on our unsecured credit facility, proceeds from property dispositions, the use of debt and equity offerings under our automatic shelf registration statement, equity issued from our at-the-market ("ATM") share offering program, other unsecured borrowings and secured mortgages.

As of September 30, 2016, we had approximately $313.7 million in cash and cash equivalents, $100.0 million in short-term investments, no balances outstanding on our $600 million unsecured credit facility, and no debt maturing through the remainder of 2016. As of the date of this filing, we had common shares having an aggregate offering price of up to $315.3 million remaining available for sale under our ATM program. We believe we are well-positioned with a strong balance sheet and sufficient liquidity to cover near-term debt maturities and new development, redevelopment, and other capital funding requirements. We will, however, continue to assess and take further actions we believe are prudent to meet our objectives and capital requirements.

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 for communities included in continuing operations are made on a dollars-per-weighted average apartment home basis in order to adjust for such changes in the number of apartment homes owned during each period. Selected weighted averages for the three and nine months ended September 30, 2016 and 2015 are as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2016			2015			2016			2015
Average monthly property revenue per apartment home	$	1,572		$	1,495		$	1,545		$	1,468
Annualized total property expenses per apartment home	$	6,884		$	6,638		$	6,682		$	6,415
Weighted average number of operating apartment homes owned 100%	46,702			47,405			47,426			46,963
Weighted average occupancy of operating apartment homes owned 100% *	95.8		%	96.1		%	95.5		%	95.8		%

* Our one student housing community is excluded from this calculation.

Management considers property net operating income ("NOI") to be an appropriate supplemental measure of operating performance to net income because it reflects the operating performance of our communities without allocation of corporate level property management overhead or general and administrative costs. We define NOI as total property income less property operating and maintenance expenses less real estate taxes. NOI is further detailed in the Property-Level NOI table as seen below. NOI is not defined by accounting principles generally accepted in the United States of America ("GAAP") and should not be considered an alternative to net income as an indication of our operating performance. Also, NOI should not be considered an alternative to net cash from operating activities as a measure of liquidity, or an indication of cash available to fund cash needs. Additionally, NOI as disclosed by other REITs may not be comparable to our calculation.

(1) Same store communities are communities we owned and were stabilized as of January 1, 2015, excluding assets held for sale. Non-same store communities are stabilized communities not owned or stabilized as of January 1, 2015, excluding assets held for sale. Management believes same store information is useful as it allows both management and investors to determine financial results over a particular period for the same set of communities. Development and lease-up communities are non-stabilized communities we have acquired or developed since January 1, 2015, excluding assets held for sale. Dispositions/other includes those communities disposed of or held for sale which are not classified as discontinued operations. Other includes non-multifamily rental properties, below market lease amortization related to acquired communities, and expenses related to land holdings not under active development.

Same Store Analysis

Same store property NOI increased approximately $5.2 million and $16.0 million for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. These increases were due to increases of approximately $6.7 million and $22.3 million in same store property revenues for the three and nine months ended September 30, 2016, respectively, partially offset by increases of approximately $1.5 million and $6.3 million in same store property expenses for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015.

The $6.7 million and $22.3 million increases in same store property revenues during the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015, were due in part to increases in same store rental revenues of approximately $4.1 million and $14.0 million during the three and nine months ended September 30, 2016, respectively, which were primarily due to a 3.1% and 3.5% increase in average rental rates for our same store portfolio during the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. The increases in same store property revenues were also due to increases of approximately $2.6 million and $8.3 million in other property revenue during the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015, primarily due to increases in income from our bulk internet rebilling program and miscellaneous income.

The $1.5 million and $6.3 million increases in same store property expenses during the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015, were primarily due to higher real estate taxes as a result of increased property valuations at a number of our communities and higher bulk internet rebilling program expenses. These increases were partially offset by decreased property insurance expenses during the nine month ended September 30, 2016, as compared to the same period in 2015.

Non-same Store and Development and Lease-up Analysis

Property NOI from non-same store and development and lease-up communities increased approximately $5.4 million and $15.9 million for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. These increases were due to increases of approximately $8.0 million and $24.6 million in revenues for the three and nine months ended September 30, 2016, respectively, partially offset by increases of approximately $2.6 million and $8.7 million in expenses for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. The increases in property revenues and expenses from our non-same store communities were primarily due to the stabilization of five operating properties during 2015 and three operating properties during the nine months ended September 30, 2016. The increases in property revenues and expenses from our development and lease-up communities were primarily due to the completion and partial lease up of one property during 2015 and two properties during the nine months ended September 30, 2016, and the partial lease-up of two properties which were under construction at September 30, 2016.

Dispositions/Other Property Analysis

Dispositions/other property NOI decreased approximately $4.7 million and $5.0 million for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. These decreases were primarily due to the dispositions of one operating property in the fourth quarter of 2015, one operating property in June 2016, and one dual-phase operating property and five other operating properties in the third quarter of 2016.

Fee and asset management income decreased approximately $0.2 million and increased approximately $0.1 million for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. The decrease for the three months ended September 30, 2016 was primarily due to lower construction fees earned resulting from a decrease in third-party construction activity and lower development and construction fees earned due to the timing of one development community started and completed by one of our Funds in 2015. The $0.1 million increase in fee and asset management fees for the nine months ended September 30, 2016 was primarily due to higher construction fees earned resulting from an increase in third-party construction activity and increased property revenue by the operating properties owned by the Funds, which resulted in increased property management fees. This increase was partially offset by a decrease in development and construction fees earned due to the timing of the commencement and completion of the development of one community by one of our Funds in 2015.

Interest and other income increased approximately $0.8 million and approximately $1.1 million for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. These increases were due to higher interest income earned on investments in cash and short-term investments due to an increase in average cash balances and an increase in average note receivable balances outstanding on our real estate secured loans to unaffiliated third parties during the three and six months ended September 30, 2016, as compared to the same periods in 2015.

Our deferred compensation plans recognized income of approximately $3.5 million and $4.8 million during the three and nine months ended September 30, 2016, respectively, and incurred losses of approximately $3.4 million and $1.9 million during the three and nine months ended September 30, 2015, respectively. These changes were related to the performance of the investments held in deferred compensation plans for participants and were directly offset by the expense (benefit) related to these plans, as discussed below.

Property management expense, which represents regional supervision and accounting costs related to property operations, decreased approximately $0.1 million and increased approximately $1.7 million for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. The decrease for the three months ended September 30, 2016 was primarily related to a decrease in expenses due to the timing of education programs to our regional employees, partially offset by increases in salaries, benefits, and incentive compensation expenses. The increase for the nine months ended September 30, 2016 was primarily due to increases in salaries, benefits, and incentive compensation expenses due to higher deferred compensation amortization resulting from the accelerated vesting relating to certain executive officers

meeting the retirement eligibility and service requirements as defined in the 2011 Share Plan, partially offset by lower discretionary costs. Property management expense was 2.5% and 2.7% of total property revenues for the three months ended September 30, 2016 and 2015, respectively, and was 2.9% and 2.8% of total property revenues for the nine months ended September 30, 2016 and 2015, respectively.

Fee and asset management expense, which represents expenses related to third-party construction projects and property management of our joint ventures, decreased approximately $0.3 million and $0.6 million for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. These decreases were primarily due to lower professional fees incurred in managing our joint ventures and lower expenses incurred as a result of decreases in development and construction activity relating to the timing of one development community started and completed by one of the Funds in 2015. The decrease for the nine months ended September 30, 2016 was partially offset by higher expenses related to an increase in third-party construction activity during the nine months ended September 30, 2016, as compared to the same period in 2015.

General and administrative expense decreased approximately $1.0 million and increased approximately $1.7 million for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. The decrease for the three months ended September 30, 2016 was primarily due to a higher amount of salary costs allocated to the operating properties sold during the third quarter 2016, partially offset by lower professional fees. The increase for the nine months ended September 30, 2016 was primarily due to increases in salaries, benefits, and incentive compensation expenses, due to higher deferred compensation amortization costs resulting from the accelerated vesting relating to certain trust managers and executive officers meeting the retirement eligibility and service requirements as defined in the 2011 Share Plan, and an increase in the value of awards granted in 2016 as compared to the value of awards which were fully vested during the same period in 2015. This increase was also due to an increase in professional fees and administrative expenses, as compared to the same period in 2015. General and administrative expenses were 4.9% and 5.5% of total property revenues and non-property income, excluding income (loss) on deferred compensation plans, for the three months ended September 30, 2016 and 2015, respectively, and 5.2% and 5.3% of total property revenues and non-property income, excluding income (loss) on deferred compensation plans, for the nine months ended September 30, 2016 and 2015, respectively.

Interest expense for the three and nine months ended September 30, 2016decreased approximately $0.6 million and $3.6 million, respectively, as compared to the same periods in 2015. The decrease for the three months ended September 30, 2016 was primarily due to lower interest expense on our unsecured credit facility as there were no balances outstanding during the three months ended September 30, 2016 as compared to having an increase in borrowings on our unsecured credit facility during the same period in 2015.

The $3.6 million decrease in interest expense for the nine months ended September 30, 2016 was primarily due to the repayment of a $250 million, 5.08% senior unsecured notes payable in June 2015. The decrease was partially offset by lower capitalized interest during the nine months ended September 30, 2016, resulting from lower average balances in our development pipeline. The decrease was further offset by an increase in interest expense relating to borrowings on our unsecured credit facility during the first six months of 2016, and higher interest expense recognized on our variable rate debt due to higher weighted average interest rates during the nine months ended September 30, 2016 as compared to the same period in 2015.

Depreciation and amortization expense increased approximately $1.5 million and $8.1 million for the three and nine months ended September 30, 2016, respectively as compared to the same periods in 2015. These increases were primarily due to the completion of units in our development pipeline, the completion of repositions, and increases in capital improvements placed in service during 2016 and 2015. These increases were partially offset by a decrease in depreciation expense related to the disposition of one operating property during the fourth quarter of 2015, one operating property in June 2016, and the disposition of one dual-phased operating property and five other operating properties during the three months ended September 30, 2016.

Our deferred compensation plans incurred expenses of approximately $3.5 million and $4.8 million during the three and nine months ended September 30, 2016, respectively, and recognized a benefit of $3.4 million and $1.9 million during the nine months ended September 30, 2015, respectively. These changes were related to the performance of the investments held in deferred compensation plans for participants and were directly offset by the income (loss) related to these plans, as discussed in the non-property income section above.

During the three months ended September 30, 2016, we recognized an approximate $262.7 million gain related to the sale of one dual-phased property and five operating properties comprised of 2,906 apartment homes as compared to no sales during the same period in 2015. During the nine months ended September 30, 2016, we also recognized an approximate $32.2 million gain related to the sale of one operating property comprised of 278 apartment homes and an approximate $0.4 million gain related to the sale of 6.3 acres of land adjacent to an operating property in Tampa, Florida. During the nine months ended September 30, 2015, we recognized an approximate $85.1 million gain on sale of two operating properties comprised of 1,116 apartment homes, and a $0.1 million gain on sale of a land holding adjacent to an operating property in Dallas, Texas.

Equity in income of joint ventures increased approximately $0.3 million and $0.6 million for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. These increases were primarily due to increases in earnings resulting from higher rental and other property revenues from the operating properties owned by the Funds and the stabilization of one operating property owned by the Funds during the first quarter of 2016. During the period from the lease-up to commencement of stabilization, we recognized our proportionate share of losses. These increases were partially offset by higher real estate taxes as a result of increased property valuations of a number of the Fund communities. These increases were further offset by increases in interest expense and property taxes incurred during the three and nine months ended September 30, 2016 by an operating property owned by one of the Funds. These expenses were capitalized during the three and nine months ended September 30, 2015 while this property was under construction.

Funds from Operations ("FFO") and Adjusted FFO ("AFFO")

Management considers FFO and AFFO to be appropriate measures of the financial performance of an equity REIT. The National Association of Real Estate Investment Trusts ("NAREIT") currently defines FFO as net income (computed in accordance with GAAP), excluding gains (or losses) associated with previously depreciated operating properties, real estate depreciation and amortization, impairments of depreciable assets, and adjustments for unconsolidated joint ventures. Our calculation of diluted FFO also assumes conversion of all potentially dilutive securities, including certain non-controlling 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 assist in the comparison of the operating performance of a company's real estate investments between periods or to different companies.

AFFO is calculated utilizing FFO less recurring capitalized expenditures which are necessary to help preserve the value of and maintain the functionality at our communities. We also consider AFFO to be a useful supplemental measure because it is frequently used by analysts and investors to evaluate a REIT's operating performance between periods or different companies. Our definition of recurring capital expenditures may differ from other REITs, and there can be no assurance our basis for computing this measure is comparable to other REITs.

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

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 equity.

Our interest expense coverage ratio, net of capitalized interest, was approximately 5.4 and 5.5 for the three and nine months ended September 30, 2016, and approximately 5.3 and 5.1 for the three and nine months ended September 30, 2015, respectively. This ratio is a method for calculating the amount of operating cash flows available to cover interest expense and is calculated by dividing interest expense for the period into the sum of property revenues and expenses, non-property income, other expenses and income from discontinued operations, after adding back depreciation, amortization, and interest expense from both continuing and discontinued operations. Approximately 78.2% and 79.9% of our properties were unencumbered at September 30, 2016 and 2015, respectively. Our weighted average maturity of debt was approximately 5.1 years at September 30, 2016.

We also intend to strengthen our capital and liquidity positions by continuing to focus on our core fundamentals, which we believe are generating positive cash flows from operations, maintaining appropriate debt levels and leverage ratios, and controlling overhead costs.

Our primary source of liquidity is cash and cash equivalents, short-term investments, and cash flows generated from operations. Other sources may include one or more of the following: availability under our unsecured credit facility, proceeds from property dispositions, the use of debt and equity offerings under our automatic shelf registration statement, equity issued

33

from our ATM program, other unsecured borrowings and secured mortgages. We believe our liquidity and financial condition are sufficient to meet all of our reasonably anticipated cash needs during 2016 including:

• normal recurring operating expenses;

• current debt service requirements, including debt maturities;

• recurring and non-recurring capital expenditures;

• reposition expenditures;

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

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

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

Cash Flows

The following is a discussion of our cash flows for the nine months ended September 30, 2016 and 2015.

Net cash from operating activities was approximately $357.5 million during the nine months ended September 30, 2016 as compared to approximately $317.7 million for the same period in 2015. The increase was primarily due to higher property-level net operating income, primarily due to the growth in revenues attributable to increased rental rates at our same store communities and growth in the number of non-same store properties resulting from the stabilization of eight operating properties in 2015 and the first nine months of 2016, the completion and partial lease-up of two operating properties during the first nine months of 2016, and the partial lease-up of two properties which were under construction at September 30, 2016. The increase was also partially due to an approximate $10.0 million bonus paid to employees in 2015 relating to the restructuring of the Funds in December 2014. The increase was partially offset by a decrease related to the disposition of 15 operating properties, a retail center, and approximately 19.6 acres of land classified as discontinued operations, as well as the disposition of one other operating property during 2015 and the disposition of one dual-phased operating property and six other operating properties during the nine months ended September 30, 2016. See further discussions of our 2016 operations as compared to 2015 in "Results of Operations."

Net cash from investing activities during the nine months ended September 30, 2016 totaled approximately $766.6 million as compared to net cash used in investing activities of approximately $231.9 million for the same period in 2015. During 2016, we received approximately $623.0 million, net of expenses, from the sale of 15 operating properties, a retail center, and approximately 19.6 acres of land classified as discontinued operations, as well as $515.8 million, net of expenses, from the sale of one dual-phase operating property and six other properties and one land holding. These inflows were partially offset by cash outflows for property development and capital improvements of approximately $262.7 million during the nine months ended September 30, 2016 as compared to approximately $328.3 million for the same period in 2015, primarily due to the completion of eight consolidated operating properties in 2015 and the nine months ended September 30, 2016, and the completion of repositions at several of our operating properties. The property development and capital improvements during the nine months ended September 30, 2016 and 2015, included the following:

	Nine Months Ended September 30,
(in millions)	2016		2015
Expenditures for new development, including land	$	171.7	$	232.2
Capitalized interest, real estate taxes, and other capitalized indirect costs	22.2		24.0
Reposition expenditures	16.5		25.3
Capital expenditures	52.3		46.8
Total	$	262.7	$	328.3

During the nine months ended September 30, 2016, cash outflows also included the purchase of a short-term investment for $100.0 million. During the nine months ended September 30, 2015, cash outflows were partially offset by proceeds of approximately $112.2 million from the sale of two operating properties and one land holding.

34

Net cash used in financing activities totaled approximately $821.0 million for the nine months ended September 30, 2016 as compared to approximately $229.3 million during the same period in 2015. During the nine months ended September 30, 2016, we had net payments of $244.0 million on our unsecured credit facility and other short-term borrowings. We also used approximately $580.5 million to pay distributions to common shareholders and non-controlling interest holders which included the payment of the $4.25 per common share special dividend paid on September 30, 2016. During the nine months ended September 30, 2015, we used $250.0 million to repay maturing unsecured notes payable, approximately $188.9 million to pay distributions to common shareholders and non-controlling interest holders, and approximately $9.5 million to acquire the remaining non-controlling interests in two consolidated joint ventures. The cash flows for the nine months ended September 30, 2015 were partially offset by net proceeds from our unsecured line of credit and other short-term borrowings of $223.0 million.

Financial Flexibility

We have a $600 millionunsecured credit facility which matures in August 2019, with two six-month options to extend the maturity date at our election to August 2020. Additionally, we have the option to further increase our credit facility to $900 million by either adding additional banks to the facility or obtaining the agreement of the existing banks to increase their commitments. The interest rate on our credit facility is based upon the London Interbank Offered Rate ("LIBOR") plus a margin which is subject to change as our credit ratings change. Advances under our credit facility 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 $300 million or the remaining amount available under our credit facility. Our credit facility is subject to customary financial covenants and limitations. We believe we are in compliance with all such financial covenants and limitations on the date of this filing.

Our credit facility provides us with the ability to issue up to $50 million in letters of credit. While our issuance of letters of credit does not increase our borrowings outstanding under our credit facility, it does reduce the amount available. At September 30, 2016, we had no balances outstanding on our credit facility and we had outstanding letters of credit totaling approximately$13.3 million, leaving approximately $586.7 millionavailable under our credit facility.

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 millionpreferred shares. At September 30, 2016, we had approximately87.5 million common shares outstanding, net of treasury shares and shares held in our deferred compensation arrangements, and no preferred shares outstanding.

In November 2014, we created an ATM share offering program through which we can, but have no obligation to, sell common shares having an aggregate offering price of up to $331.3 million, in amounts and at times as we determine, into the existing trading market at current market prices as well as through privately 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. We intend to use the net proceeds from any future sales under the ATM program for general corporate purposes, which may include reducing future borrowings under our unsecured credit facility, the repayment of other indebtedness, the redemption or other repurchase of outstanding debt or equity securities, funding for development, redevelopment and investment projects and financing for acquisitions. As of the date of this filing, we had common shares having an aggregate offering price of up to $315.3 million remaining available for sale under the ATM program.

We believe our ability to access capital markets is enhanced by our senior unsecured debt ratings by Fitch, Moody's, and Standard and Poor's, which are currently A- with stable outlook, Baa1 with positive outlook, and BBB+ with stable outlook, respectively. We believe our ability to access capital markets is also enhanced 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 credit facility. As of the date of this filing, we have no debt maturing through the remainder of 2016. See Note 7, "Notes Payable," in the notes to Condensed Consolidated Financial Statements for further discussion of scheduled maturities.

We estimate the additional cost to complete the construction of seven consolidated projects to be approximately $212.6 million. Of this amount, we expect to incur costs between approximately $40 million and $45 million during the remainder of 2016 and to incur the remaining costs during 2017 and 2018. Additionally, we expect to incur costs up to $10 million related to

35

the start of new development activities, between approximately $1 million and $2 million of additional redevelopment expenditures and between approximately $14 million and $16 million of additional recurring capital expenditures during the remainder of 2016.

We intend to meet our near-term liquidity requirements through a combination of one or more of the following: cash and cash equivalents, short-term investments, cash flows generated from operations, draws on our unsecured credit facility, proceeds from property dispositions, the use of debt and equity offerings under our automatic shelf registration statement, equity issued from our ATM share offering program, other unsecured borrowings and secured mortgages. We intend to evaluate our operating property and land development portfolio and plan to continue our practice of selective dispositions as market conditions warrant and opportunities arise.

As a REIT, we are subject to a number of organizational and operational requirements, including a requirement to distribute current dividends to our shareholders equal to a minimum of 90% of our annual taxable income. In order to minimize paying income taxes, our general policy is to distribute at least 100% of our taxable income. In September 2016, our Board of Trust Managers declared a special dividend of $4.25 per common share and a quarterly dividend of $0.75 per common share to our common shareholders of record as of September 23, 2016 and September 30, 2016, respectively. The special dividend, consisting primarily of gains on dispositions completed in 2016, was paid on September 30, 2016 and the quarterly dividend was paid on October 17, 2016. We paid equivalent amounts per unit to holders of the common operating partnership units. Excluding the special dividend and assuming similar quarterly dividend distributions for the remainder of 2016, our annualized dividend rate would be $3.00 per share or unit for the year ending December 31, 2016.

Off-Balance Sheet Arrangements

The joint ventures in which we have an interest have been funded in part with secured, third-party debt. At September 30, 2016, our unconsolidated joint ventures had outstanding debt of approximately $521.0 million, of which our proportionate share was approximately $163.1 million. As of September 30, 2016, we had no outstanding guarantees related to the debt of our unconsolidated joint ventures.

Inflation

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

Critical Accounting Policies

Our critical accounting policies have not changed from information reported in our Annual Report on Form 10-K for the year ended December 31, 2015.

Recent Accounting Pronouncements. See Note 2, "Summary of Significant Accounting Policies and Recent Accounting Pronouncements," in the notes to Condensed Consolidated Financial Statements for further discussion of recent accounting pronouncements issued during the nine months ended September 30, 2016.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

No material changes to our exposures to market risk have occurred since our Annual Report on Form 10-K for the year ended December 31, 2015.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures.

Description of Business

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 September 30, 2016, we owned interests in, operated, or were developing 158 multifamily properties comprised of 54,925 apartment homes across the United States. Of the 158 properties, seven properties were under construction which will consist of a total of 2,419 apartment homes when completed. We also own land holdings which we may develop into multifamily communities in the future.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies and Recent Accounting Pronouncements

2. Summary of Significant Accounting Policies and Recent Accounting Pronouncements

Principles of Consolidation. Our condensed consolidated financial statements include our accounts and the accounts of other subsidiaries and joint ventures (including partnerships and limited liability companies) over which we have control. All intercompany transactions, balances, and profits have been eliminated in consolidation. Investments acquired or created are 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, or non-managing members, to assess whether the limited partners, or non-managing members, hold substantive kick-out or participating rights which indicate we do not have a controlling financial interest. At September 30, 2016, two of our consolidated operating partnerships are VIEs, of which we held between 92% and 94% of the outstanding common limited partnership units and the sole 1% general partnership interest of each consolidated operating partnership. As we are considered the primary beneficiary, we would continue to consolidate these operating partnerships.

Interim Financial Reporting. We have prepared these unaudited financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial statements and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, these statements do not include all information and footnote disclosures required for annual statements. While we believe the disclosures presented are adequate for interim reporting, these interim unaudited financial statements should be read in conjunction with the audited financial statements and notes included in our 2015 Annual Report on Form 10-K. Certain insignificant amounts in the unaudited condensed consolidated statements of cash flows for the nine months ended September 30, 2015 have been reclassified to conform to the current year presentation. These reclassifications had no impact on our condensed consolidated cash flows from operating, investing or financing activities. As a result of our adoption of Accounting Standards Update 2015-03 ("ASU 2015-03"),  "Simplifying the Presentation of Debt Issuance Costs," as supplemented by Accounting Standards Update 2015-15 ("ASU 2015-15"), "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements," as of December 31, 2015, we reclassified $0.3 million and $0.9 million of deferred financing charges relating to our unsecured credit facility to depreciation and amortization in our condensed consolidated statements of income and comprehensive income for the three and nine months ended September 30, 2015, respectively. We also reclassified $0.4 million and $1.3 million of deferred charges for the three and nine months ended September 30, 2015, respectively, to interest expense. In the opinion of management, all adjustments and eliminations, consisting of normal recurring adjustments, necessary for a fair representation of our financial statements for the interim period reported have been included. Operating results for the three and nine months ended September 30, 2016 are not necessarily indicative of the results which may be expected for the full year.

Asset Impairment. Long-lived assets are reviewed for impairment annually or whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Impairment 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, but not limited to, 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 utilize 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 three and nine months ended September 30, 2016 or 2015.

The value of our properties under development depends on market conditions, including, but not limited to, 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.

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 certain activities necessary to prepare the underlying real estate 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 $4.5 million and $4.3 million for the three months ended September 30, 2016 and 2015, respectively, and was approximately $13.8 million and $14.9 million for the nine months ended September 30, 2016 and 2015, respectively. Capitalized real estate taxes were approximately $0.6 million and 0.9 million for the three months ended September 30, 2016 and 2015, respectively, and were approximately $3.3 million and $2.9 million for the nine months ended September 30, 2016 and 2015, respectively.

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 above and below market leases)	underlying lease term

Discontinued Operations. A property is classified as a discontinued operation when the disposal represents a strategic shift, such as disposal of a major line of business, a major geographical area or a major equity investment. The results of operations for properties sold or classified as held for sale at the end of the period, and meeting the above criteria of discontinued operations, are classified as discontinued operations for all periods presented. 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 meeting the criteria of discontinued operations 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 condensed consolidated balance sheets for all periods presented. Subsequent to classification of a property as held for sale, no further depreciation is recorded. Properties sold by our unconsolidated entities which do not meet the above criteria of discontinued operations 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 GAAP, provided various criteria relating to the terms of sale and any subsequent involvement with the real estate sold are satisfied.

See Note 5, "Acquisitions, Dispositions and Discontinued Operations and Assets Held for Sale," for a discussion of discontinued operations for the three and nine months ended September 30, 2016 and 2015.

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 expect to receive to sell an asset, or pay to transfer a liability, in an orderly transaction with a market participant at the measurement date under current market conditions. 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 Measurements. 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 condensed consolidated balance sheets. The inputs associated with the valuation of our recurring deferred compensation plan investments are included in Level 1 of the fair value hierarchy.

Non-Recurring Fair Value Measurements. 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 if they are impaired using the fair value methodologies used to measure long-lived assets described above at "Asset Impairment." Non-recurring fair value disclosures are not provided for impairments on assets disposed during the period because they are no longer owned by us. The inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy, unless a quoted price for a similar long-lived asset in an active market exists, at which time they are included in Level 2 of the fair value hierarchy.

Financial Instrument Fair Value Disclosures. As of September 30, 2016 and December 31, 2015, the carrying values of cash and cash equivalents, short-term investments, 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. The carrying values of our notes receivable also approximate their fair values, which are based on certain factors, such as market interest rates, terms of the note and credit worthiness of the borrower. These financial instruments utilize Level 3 inputs. 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.

Notes Receivable. Our notes receivable, which are included in other assets, net, in our condensed consolidated balance sheets, relate to real estate secured loans to unaffiliated third parties. At September 30, 2016 and December 31, 2015, we had outstanding notes receivable balances of approximately $19.9 million and $13.2 million, respectively, and the weighted average interest rate on such notes was approximately 4.1% for each of the nine months ended September 30, 2016 and 2015. At September 30, 2016, we were also committed to funding additional amounts under one of the loans in the amount of approximately $1.5 million. Interest is recognized over the lives of the notes and is included in interest and other income in our consolidated statements of income and comprehensive income. We consider a note receivable to be impaired if it is probable we will not collect all contractually due principal and interest. We do not accrue interest when a note is considered impaired and an allowance is recorded for any principal and previously accrued interest which is not believed to be collectible.

Short-term Investments. At September 30, 2016, our short-term investments consists of certificates of deposit which have maturities of more than three months but less than one year.  The carrying value of our short-term investments approximate their fair values due to the short-term nature of these investments.

Recent Accounting Pronouncements. In January 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2016-01 ("ASU 2016-01"), "Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01 changes certain recognition, measurement, presentation, and disclosure requirements for financial instruments. This standard requires all equity investments, except those accounted for under the equity method of accounting or resulting in consolidation, to be measured at fair value with changes in fair value recognized in net income. This standard also simplifies the impairment assessment for equity investments without readily determinable fair values, amends the presentation requirements for changes in the fair value of financial liabilities, requires presentation of financial instruments by measurement category and form of financial asset, and eliminates the requirement to disclose the methods and significant assumptions used in estimating the fair value of financial instruments. ASU 2016-01 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is not permitted except for the amended presentation requirements for changes in the fair value of financial liabilities. We expect to adopt ASU 2016-01 as of January 1, 2018, and do not expect it to have a material impact on our consolidated financial statements upon adoption.

In February 2016, the FASB issued Accounting Standards Update 2016-02 ("ASU 2016-02"), "Leases." ASU 2016-02 requires lessees to recognize right-of-use assets and lease liabilities on the balance sheet for all leases of property, plant and equipment with lease terms greater than 12 months. Prior to this accounting standard, only capital leases were recognized on the balance sheet. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. This standard must be applied as of the beginning of the earliest comparative period presented in the year of adoption. We expect to adopt ASU 2016-02 as of January 1, 2019. We are currently evaluating the impact this standard may have on our consolidated financial statements upon adoption in conjunction with Accounting Standards Update 2014-09 ("ASU 2014-09"), "Revenue from Contracts with Customers" discussed below.

In May 2014, the FASB issued ASU 2014-09, which provides a single comprehensive revenue recognition model for contracts with customers (excluding certain contracts, such as lease contracts) to improve comparability within industries. ASU 2014-09 requires an entity to recognize revenue to reflect the transfer of goods or services to customers at an amount the entity expects to be paid in exchange for those goods and services and provide enhanced disclosures, all to provide more comprehensive guidance for transactions such as service revenue and contract modifications. In August 2015, the FASB deferred the effective date of ASU 2014-09 by one year, and it is now effective for interim and annual periods beginning after December 15, 2017. In March 2016, the FASB issued Accounting Standards Update 2016-08 ("ASU 2016-08"), "Principal versus Agent Considerations (Reporting Revenue Gross versus Net)." ASU 2016-08 amends ASU 2014-09 to assist in the decision of whether an entity is a principal or agent in a revenue transaction in which a third party is involved in providing goods or services to a customer of the entity. Early adoption of ASU 2014-09 is permitted but not before the original effective date, which applied to interim and annual periods beginning after December 15, 2016. ASU 2014-09 may be applied using either a full retrospective or a modified approach upon adoption. We expect to adopt this standard as of January 1, 2018, and we are currently evaluating the impact this standard may have on our consolidated financial statements upon adoption in conjunction with ASU 2016-02.

In March 2016, the FASB issued ASU 2016-07, "Simplifying the Transition to the Equity Method of Accounting." ASU 2016-07 eliminates the requirement to retroactively adjust an investment when the investment qualifies for use of the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence. Additionally, if the investment was previously accounted for as an available-for-sale security, any unrealized holding gain or loss in accumulated other comprehensive income would be recognized in earnings at the date the investment qualifies for the equity method of accounting. ASU 2016-07 is effective for interim and annual periods beginning after December 15, 2016, and early adoption is permitted. This standard must be applied prospectively. We expect to adopt ASU 2016-07 as of January 1, 2017, and do not expect it to have a material impact on our consolidated financial statements upon adoption.

In March 2016, the FASB issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 amends several aspects of the accounting for share-based payment transactions, including the income tax consequences, accrual of compensation cost, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016, and early adoption is permitted. The amendments in this standard must be applied prospectively, retrospectively, or as of the beginning of the earliest comparative period presented in the year of adoption, depending on the type of amendment. We expect to adopt ASU 2016-09 as of January 1, 2017, and we do not expect it to have a material impact on our consolidated financial statements upon adoption.

In August 2016, the FASB issued Accounting Standards Update 2016-15 ("ASU 2016-15"), "Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)." ASU 2016-15 clarifies how several specific cash receipts and cash payments are to be presented and classified on the statement of cash flows, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration made after a business combination, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of predominance principle. ASU 2016-15 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted. Each amendment in this standard must be applied prospectively, retrospectively, or as of the beginning of the earliest comparative period presented in the year of adoption, depending on the type of amendment. We expect to adopt ASU 2016-15 as of January 1, 2018, and we are currently evaluating the impact this standard may have on our consolidated financial statements upon adoption.

Earnings Per Share [Abstract]

Per Share Data

3. Per Share Data

Basic earnings per share is computed using net income attributable to common shareholders and the weighted average number of common shares outstanding. Diluted earnings per share reflects 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 2.4 million and 2.6 million for the three months ended September 30, 2016 and 2015, respectively, and was approximately 2.5 million and 2.6 million for the nine months ended September 30, 2016 and 2015, 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 calculations as they are anti-dilutive.

The following table presents information necessary to calculate basic and diluted earnings per share for the periods indicated:

4. Common Shares

In November 2014, we created an ATM share offering program through which we can, but have no obligation to, sell common shares having an aggregate offering price of up to $331.3 million, with $315.3 million remaining available for sale as of the date of this filing. There were no shares sold during the nine months ended September 30, 2016 or 2015, and no shares have been sold through the date of this filing.

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 repurchased 4.3 million shares for a total of approximately $230.2 million from April 2007 through December 31, 2008 and there have not been any shares repurchased subsequent to that date. As of the date of this filing, the remaining dollar value of our common equity securities authorized to be repurchased under the program was approximately $269.8 million.

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 millionpreferred shares. At September 30, 2016, we had approximately87.5 million common shares outstanding, net of treasury shares and shares held in our deferred compensation arrangements, and no preferred shares outstanding.

In September 2016, our Board of Trust Managers declared a quarterly dividend of $0.75 per common share to our shareholders of record as of September 30, 2016. The quarterly dividend was paid on October 17, 2016. We paid equivalent amounts per unit to holders of the common unit partnerships.

In addition to our quarterly dividend, our Board of Trust Managers declared a special dividend of $4.25 per common share to our common shareholders of record as of September 23, 2016, consisting primarily of gains on dispositions completed in 2016. The special dividend was paid on September 30, 2016. We also paid equivalent amounts per unit to holders of the common operating partnership units.

6. Investments in Joint Ventures

As of September 30, 2016, our equity investments in unconsolidated joint ventures, which we account for utilizing the equity method of accounting, consisted of three discretionary investment funds (collectively, the "Funds"), with our ownership percentages ranging from 20% to 31.3%. One of the Funds, in which we have a 20% ownership interest, did not own any properties for any periods presented. We provide property and asset management and other services to the Funds which own operating properties and we may also provide construction and development services to the Funds which own properties under development. The following table summarizes the combined balance sheet and statement of income data for the Funds as of and for the periods presented:

(in millions)	September 30, 2016		December 31, 2015
Total assets	$	729.3	$	748.0

(1) Equity in income excludes our ownership interest of fee income from various services provided by us to the Funds.

The Funds have been funded in part with secured third-party debt and, as of September 30, 2016, we had no outstanding guarantees related to debt of the Funds.

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 may earn a promoted equity interest if certain thresholds are met. We eliminate fee income for services provided to these joint ventures to the extent of our ownership. Fees earned for these services, net of eliminations, were approximately $1.3 million and $1.4 million for the three months ended September 30, 2016 and 2015, respectively, and were approximately $4.0 million and $4.4 million for the nine months ended September 30, 2016 and 2015, respectively.

We have a $600 millionunsecured credit facility which matures inAugust 2019, with two six-month options to extend the maturity date at our election to August 2020. Additionally, we have the option to further increase our credit facility to $900 millionby either adding additional banks to the facility or obtaining the agreement of the existing banks to increase their commitments. The interest rate on our credit facility is based upon the London Interbank Offered Rate ("LIBOR") plus a margin which is subject to change as our credit ratings change. Advances under our credit facility 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$300 millionor the remaining amount available under our credit facility. Our credit facility is subject to customary financial covenants and limitations. We believe we are in compliance with all such financial covenants and limitations on the date of this filing.

Our credit facility provides us with the ability to issue up to $50 million in letters of credit. While our issuance of letters of credit does not increase our borrowings outstanding under our credit facility, it does reduce the amount available. At September 30, 2016, we had no balances outstanding on our $600 millioncredit facility and we had outstanding letters of credit totaling approximately$13.3 million, leaving approximately $586.7 millionavailable under our credit facility.

At September 30, 2016 and 2015, we had outstanding floating rate debt of approximately $206.1 million and $431.0 million, respectively, which also included our unsecured credit facility and unsecured short-term borrowings at September 30, 2015. The weighted average interest rate on such debt was approximately 1.4% and 1.0% for the nine months ended September 30, 2016 and 2015, respectively.

Share-based Compensation and Non-Qualified Deferred Compensation Plan

Share-based Compensation [Abstract]

Share-based Compensation and Non-Qualified Deferred Compensation Plan

8. Share-based Compensation and Non-Qualified Deferred Compensation Plan

Incentive Compensation. During the second quarter of 2011, our Board of Trust Managers adopted, and 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.

At September 30, 2016, approximately 3.7 million fungible units were available under the 2011 Share Plan, which results in approximately 1.1 million common shares which may 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 2011 Share Plan, in increments ranging from 20% to 33.33% per year on each of the anniversaries of the date of grant. The 2011 Share 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 0.1 million options were exercised during the nine months ended September 30, 2016 and 2015, respectively. The total intrinsic value of options exercised was approximately $8.9 million and $2.0 million during the nine months ended September 30, 2016 and 2015, respectively. At September 30, 2016, there was no unrecognized compensation cost related to unvested options. At September 30, 2016, all options outstanding were exercisable and had a weighted average remaining life of approximately 2.2 years.

The following table summarizes outstanding share options, all of which were exercisable, at September 30, 2016:

	Options Outstanding and Exercisable (1)
Exercise Prices	Number	Weighted Average Price
$30.06	65,460
$75.17	26,752
$85.05	12,854
Total options	105,066	$	48.27

(1) The aggregate intrinsic value of options outstanding and exercisable at September 30, 2016 was $3.7 million. The aggregate intrinsic value was calculated as the excess, if any, between our closing share price of $83.74 per share on September 30, 2016 and the strike price of the underlying award.

Options Granted and Valuation Assumptions. During the nine months ended September 30, 2016, we granted approximately 13 thousand reload options. Reload options are granted for the number of shares tendered as payment for the exercise price upon the exercise of an option with a reload provision. The reload options granted have an exercise price equal to the fair market value of a common share on the date of grant and expire on the same date as the original options which were exercised. The reload options granted during the nine months ended September 30, 2016 vested immediately and approximately $0.1 million was expensed on the reload date. We estimate the fair values of each option award including reloads on the date of grant using the Black-Scholes option pricing model. The following assumptions were used for the reload options granted during the nine months ended September 30, 2016:

	Nine Months Ended September 30, 2016
Weighted average fair value of options granted	$6.71
Expected volatility	18.0%
Risk-free interest rate	0.9%
Expected dividend yield	3.8%
Expected life	3 years

Our computation of expected volatility for 2016 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, and 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 based on the historical dividend yield over the expected term of the options granted. Our computation of expected life is based upon historical experience of similar awards, giving consideration to the contractual terms of the share-based awards.

Share Awards and Vesting. Share awards for employees generally have a vesting period of three to five years. The compensation cost for share awards is generally based on the market value of the shares on the date of grant and is amortized over the vesting period. In the event the holder of the share awards will reach both the retirement eligibility age of 65 years and the service requirements as defined in the 2011 Share Plan before the term in which the awards are scheduled to vest, the value of the share awards is amortized from the date of grant to the individual's retirement eligibility date. To estimate forfeitures, we use actual forfeiture history. At September 30, 2016, the unamortized value of previously issued unvested share awards was approximately $31.9 million, which is expected to be amortized over the next two years. The total fair value of shares vested during the nine months ended September 30, 2016 and 2015 was approximately $22.6 million and $18.1 million, respectively.

Total compensation cost for option and share awards charged against income was approximately $5.4 million and $4.8 million for the three months ended September 30, 2016 and 2015, respectively, and approximately $16.3 million and $13.7 million for the nine months ended September 30, 2016 and 2015, respectively. Total capitalized compensation cost for option and share awards was approximately $1.0 million and $0.9 million for the three months ended September 30, 2016 and 2015, respectively, and approximately $2.8 million and $2.6 million for the nine months ended September 30, 2016 and 2015, respectively.

The following table summarizes activity under our share incentive plans for the nine months ended September 30, 2016:

	Options Outstanding		Weighted Average Exercise / Grant Price		Nonvested Share Awards Outstanding		Weighted Average Exercise /  Grant Price
Options and nonvested share awards outstanding at December 31, 2015	295,205		$	42.49	750,246		$	68.09

Commitments and Contingencies

10. Commitments and Contingencies

Construction Contracts. As of September 30, 2016, we estimate the total additional cost to complete the seven consolidated projects currently under construction to be approximately $212.6 million. We expect to fund this amount through a combination of one or more of the following: cash and cash equivalents, short-term investments, cash flows generated from operations, draws on our unsecured credit facility, proceeds from property dispositions, the use of debt and equity offerings under our automatic shelf registration statement, equity issued from our ATM program, other unsecured borrowings and secured mortgages.

Other Commitments and 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 September 30, 2016, we had no earnest money deposits for potential acquisitions of land which are included in other assets, net in our condensed consolidated balance sheets.

Lease Commitments. At September 30, 2016, we had long-term leases covering certain land, office facilities, and equipment. Rental expense totaled approximately $1.0 million and $0.8 million for the three months ended September 30, 2016 and 2015, respectively, and approximately $3.1 million and $2.4 million for the nine months ended September 30, 2016 and 2015, respectively. Minimum annual rental commitments for the remainder of 2016 are $0.7 million, and for the years ending December 31, 2017 through 2020 are approximately $2.9 million, $2.7 million, $2.5 million, and $2.5 million, respectively, and approximately $11.1 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 or dispose of land or of a community in our sole discretion may be limited to varying degrees in our existing joint venture agreements and may be limited to varying degrees depending on the terms of future joint venture agreements.

11. Income Taxes

We have maintained and intend to maintain our election as a REIT under the Internal Revenue Code of 1986, as amended. In order for us to continue to qualify as a REIT we must meet a number of organizational and operational requirements, including a requirement to distribute annual dividends to our shareholders equal to a minimum of 90% of our adjusted taxable income. As a REIT, we generally will not be subject to federal income tax on our taxable income at the corporate level to the extent such income is distributed to our shareholders annually. If our taxable income exceeds our dividends in a tax year, REIT tax rules allow us to designate dividends from the subsequent tax year in order to avoid current taxation on undistributed income. If we fail to qualify as a REIT in any taxable year, we will be subject to federal and state income taxes at regular corporate rates, including any applicable alternative minimum tax. In addition, we may not be able to requalify as a REIT for the four subsequent taxable years. Historically, we have incurred only state and local income, franchise, and excise taxes. Taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to applicable federal, state, and local income taxes. Our consolidated operating partnerships are flow-through entities and are not subject to federal income taxes at the entity level.

We have recorded income, franchise, and excise taxes in the condensed consolidated statements of income and comprehensive income for the three and nine months ended September 30, 2016 and 2015 as income tax expense. Income taxes for the three and nine months ended September 30, 2016 primarily related to state income tax and federal taxes on certain of our taxable REIT subsidiaries. We have no significant temporary or permanent differences or tax credits associated with our taxable REIT subsidiaries.

We believe we have no uncertain tax positions or unrecognized tax benefits requiring disclosure as of and for the nine months ended September 30, 2016.

Summary of Significant Accounting Policies and Recent Accounting Pronouncements (Policies)

Sep. 30, 2016

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation. Our condensed consolidated financial statements include our accounts and the accounts of other subsidiaries and joint ventures (including partnerships and limited liability companies) over which we have control. All intercompany transactions, balances, and profits have been eliminated in consolidation. Investments acquired or created are 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, or non-managing members, to assess whether the limited partners, or non-managing members, hold substantive kick-out or participating rights which indicate we do not have a controlling financial interest. At September 30, 2016, two of our consolidated operating partnerships are VIEs, of which we held between 92% and 94% of the outstanding common limited partnership units and the sole 1% general partnership interest of each consolidated operating partnership. As we are considered the primary beneficiary, we would continue to consolidate these operating partnerships.

Interim Financial Reporting

Interim Financial Reporting. We have prepared these unaudited financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial statements and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, these statements do not include all information and footnote disclosures required for annual statements. While we believe the disclosures presented are adequate for interim reporting, these interim unaudited financial statements should be read in conjunction with the audited financial statements and notes included in our 2015 Annual Report on Form 10-K. Certain insignificant amounts in the unaudited condensed consolidated statements of cash flows for the nine months ended September 30, 2015 have been reclassified to conform to the current year presentation. These reclassifications had no impact on our condensed consolidated cash flows from operating, investing or financing activities. As a result of our adoption of Accounting Standards Update 2015-03 ("ASU 2015-03"),  "Simplifying the Presentation of Debt Issuance Costs," as supplemented by Accounting Standards Update 2015-15 ("ASU 2015-15"), "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements," as of December 31, 2015, we reclassified $0.3 million and $0.9 million of deferred financing charges relating to our unsecured credit facility to depreciation and amortization in our condensed consolidated statements of income and comprehensive income for the three and nine months ended September 30, 2015, respectively. We also reclassified $0.4 million and $1.3 million of deferred charges for the three and nine months ended September 30, 2015, respectively, to interest expense. In the opinion of management, all adjustments and eliminations, consisting of normal recurring adjustments, necessary for a fair representation of our financial statements for the interim period reported have been included. Operating results for the three and nine months ended September 30, 2016 are not necessarily indicative of the results which may be expected for the full year.

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, but not limited to, 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 utilize 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 three and nine months ended September 30, 2016 or 2015.

The value of our properties under development depends on market conditions, including, but not limited to, 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.

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 certain activities necessary to prepare the underlying real estate 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 $4.5 million and $4.3 million for the three months ended September 30, 2016 and 2015, respectively, and was approximately $13.8 million and $14.9 million for the nine months ended September 30, 2016 and 2015, respectively. Capitalized real estate taxes were approximately $0.6 million and 0.9 million for the three months ended September 30, 2016 and 2015, respectively, and were approximately $3.3 million and $2.9 million for the nine months ended September 30, 2016 and 2015, respectively.

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 above and below market leases)	underlying lease term

Discontinued Operations

Discontinued Operations. A property is classified as a discontinued operation when the disposal represents a strategic shift, such as disposal of a major line of business, a major geographical area or a major equity investment. The results of operations for properties sold or classified as held for sale at the end of the period, and meeting the above criteria of discontinued operations, are classified as discontinued operations for all periods presented. 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 meeting the criteria of discontinued operations 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 condensed consolidated balance sheets for all periods presented. Subsequent to classification of a property as held for sale, no further depreciation is recorded. Properties sold by our unconsolidated entities which do not meet the above criteria of discontinued operations 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 GAAP, provided various criteria relating to the terms of sale and any subsequent involvement with the real estate sold are satisfied.

See Note 5, "Acquisitions, Dispositions and Discontinued Operations and Assets Held for Sale," for a discussion of discontinued operations for the three and nine months ended September 30, 2016 and 2015.

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 expect to receive to sell an asset, or pay to transfer a liability, in an orderly transaction with a market participant at the measurement date under current market conditions. 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 Measurements. 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 condensed consolidated balance sheets. The inputs associated with the valuation of our recurring deferred compensation plan investments are included in Level 1 of the fair value hierarchy.

Non-Recurring Fair Value Measurements. 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 if they are impaired using the fair value methodologies used to measure long-lived assets described above at "Asset Impairment." Non-recurring fair value disclosures are not provided for impairments on assets disposed during the period because they are no longer owned by us. The inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy, unless a quoted price for a similar long-lived asset in an active market exists, at which time they are included in Level 2 of the fair value hierarchy.

Financial Instrument Fair Value Disclosures. As of September 30, 2016 and December 31, 2015, the carrying values of cash and cash equivalents, short-term investments, 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. The carrying values of our notes receivable also approximate their fair values, which are based on certain factors, such as market interest rates, terms of the note and credit worthiness of the borrower. These financial instruments utilize Level 3 inputs. 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.

Notes Receivable

Notes Receivable. Our notes receivable, which are included in other assets, net, in our condensed consolidated balance sheets, relate to real estate secured loans to unaffiliated third parties. At September 30, 2016 and December 31, 2015, we had outstanding notes receivable balances of approximately $19.9 million and $13.2 million, respectively, and the weighted average interest rate on such notes was approximately 4.1% for each of the nine months ended September 30, 2016 and 2015. At September 30, 2016, we were also committed to funding additional amounts under one of the loans in the amount of approximately $1.5 million. Interest is recognized over the lives of the notes and is included in interest and other income in our consolidated statements of income and comprehensive income. We consider a note receivable to be impaired if it is probable we will not collect all contractually due principal and interest. We do not accrue interest when a note is considered impaired and an allowance is recorded for any principal and previously accrued interest which is not believed to be collectible.

Short-term Investments

Short-term Investments. At September 30, 2016, our short-term investments consists of certificates of deposit which have maturities of more than three months but less than one year.  The carrying value of our short-term investments approximate their fair values due to the short-term nature of these investments.

Recent Accounting Pronouncements

Recent Accounting Pronouncements. In January 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2016-01 ("ASU 2016-01"), "Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01 changes certain recognition, measurement, presentation, and disclosure requirements for financial instruments. This standard requires all equity investments, except those accounted for under the equity method of accounting or resulting in consolidation, to be measured at fair value with changes in fair value recognized in net income. This standard also simplifies the impairment assessment for equity investments without readily determinable fair values, amends the presentation requirements for changes in the fair value of financial liabilities, requires presentation of financial instruments by measurement category and form of financial asset, and eliminates the requirement to disclose the methods and significant assumptions used in estimating the fair value of financial instruments. ASU 2016-01 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is not permitted except for the amended presentation requirements for changes in the fair value of financial liabilities. We expect to adopt ASU 2016-01 as of January 1, 2018, and do not expect it to have a material impact on our consolidated financial statements upon adoption.

In February 2016, the FASB issued Accounting Standards Update 2016-02 ("ASU 2016-02"), "Leases." ASU 2016-02 requires lessees to recognize right-of-use assets and lease liabilities on the balance sheet for all leases of property, plant and equipment with lease terms greater than 12 months. Prior to this accounting standard, only capital leases were recognized on the balance sheet. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. This standard must be applied as of the beginning of the earliest comparative period presented in the year of adoption. We expect to adopt ASU 2016-02 as of January 1, 2019. We are currently evaluating the impact this standard may have on our consolidated financial statements upon adoption in conjunction with Accounting Standards Update 2014-09 ("ASU 2014-09"), "Revenue from Contracts with Customers" discussed below.

In May 2014, the FASB issued ASU 2014-09, which provides a single comprehensive revenue recognition model for contracts with customers (excluding certain contracts, such as lease contracts) to improve comparability within industries. ASU 2014-09 requires an entity to recognize revenue to reflect the transfer of goods or services to customers at an amount the entity expects to be paid in exchange for those goods and services and provide enhanced disclosures, all to provide more comprehensive guidance for transactions such as service revenue and contract modifications. In August 2015, the FASB deferred the effective date of ASU 2014-09 by one year, and it is now effective for interim and annual periods beginning after December 15, 2017. In March 2016, the FASB issued Accounting Standards Update 2016-08 ("ASU 2016-08"), "Principal versus Agent Considerations (Reporting Revenue Gross versus Net)." ASU 2016-08 amends ASU 2014-09 to assist in the decision of whether an entity is a principal or agent in a revenue transaction in which a third party is involved in providing goods or services to a customer of the entity. Early adoption of ASU 2014-09 is permitted but not before the original effective date, which applied to interim and annual periods beginning after December 15, 2016. ASU 2014-09 may be applied using either a full retrospective or a modified approach upon adoption. We expect to adopt this standard as of January 1, 2018, and we are currently evaluating the impact this standard may have on our consolidated financial statements upon adoption in conjunction with ASU 2016-02.

In March 2016, the FASB issued ASU 2016-07, "Simplifying the Transition to the Equity Method of Accounting." ASU 2016-07 eliminates the requirement to retroactively adjust an investment when the investment qualifies for use of the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence. Additionally, if the investment was previously accounted for as an available-for-sale security, any unrealized holding gain or loss in accumulated other comprehensive income would be recognized in earnings at the date the investment qualifies for the equity method of accounting. ASU 2016-07 is effective for interim and annual periods beginning after December 15, 2016, and early adoption is permitted. This standard must be applied prospectively. We expect to adopt ASU 2016-07 as of January 1, 2017, and do not expect it to have a material impact on our consolidated financial statements upon adoption.

In March 2016, the FASB issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 amends several aspects of the accounting for share-based payment transactions, including the income tax consequences, accrual of compensation cost, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016, and early adoption is permitted. The amendments in this standard must be applied prospectively, retrospectively, or as of the beginning of the earliest comparative period presented in the year of adoption, depending on the type of amendment. We expect to adopt ASU 2016-09 as of January 1, 2017, and we do not expect it to have a material impact on our consolidated financial statements upon adoption.

In August 2016, the FASB issued Accounting Standards Update 2016-15 ("ASU 2016-15"), "Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)." ASU 2016-15 clarifies how several specific cash receipts and cash payments are to be presented and classified on the statement of cash flows, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration made after a business combination, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of predominance principle. ASU 2016-15 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted. Each amendment in this standard must be applied prospectively, retrospectively, or as of the beginning of the earliest comparative period presented in the year of adoption, depending on the type of amendment. We expect to adopt ASU 2016-15 as of January 1, 2018, and we are currently evaluating the impact this standard may have on our consolidated financial statements upon adoption.
