PART I

Item 1. Business

General

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. Unless the context requires otherwise, “we,” “our,” “us,” and the “Company” refer to Camden Property Trust and its consolidated subsidiaries. Our multifamily apartment communities are referred to as “communities,” “multifamily communities,” “properties,” or “multifamily properties” in the following discussion.

Our corporate offices are located at 11 Greenway Plaza, Suite 2400, Houston, Texas 77046 and our telephone number is (713) 354-2500. Our website is located at www.camdenliving.com.

Narrative Description of Business

As of December 31, 2017, we owned interests in, operated, or were developing 162 multifamily properties comprised of 55,143 apartment homes across the United States. Of the 162 properties, seven properties were under construction and will consist of a total of 2,110 apartment homes when completed. We also own land holdings which we may develop into multifamily communities in the future.

Operating and Business Strategy

We believe producing consistent earnings growth through property operations, development and acquisitions, achieving market balance, and recycling capital are crucial factors to our success. We rely heavily on our sophisticated property management capabilities and innovative operating strategies to help us maximize the earnings potential of our communities.

Real Estate Investments and Market Balance. We believe we are well positioned in our current markets and have the expertise to take advantage of new opportunities as they arise. These capabilities, combined with what we believe is a conservative financial structure, should allow us to concentrate our growth efforts toward selective opportunities to enhance our strategy of having a geographically diverse portfolio of assets which meet the requirements of our residents.

We continue to operate in our core markets which we believe provides an advantage due to economies of scale. We believe, where possible, it is best to operate with a strong base of properties in order to benefit from the personnel allocation and the market strength associated with managing multiple properties in the same market. However, consistent with our goal of generating sustained earnings growth, we intend to selectively dispose of properties and redeploy capital for various strategic reasons, including if we determine a property cannot meet our long-term earnings growth expectations.

We try to maximize capital appreciation of our properties by investing in markets characterized by conditions favorable to multifamily property appreciation. These markets generally feature the following:

• Strong economic growth leading to household formation and job growth, which in turn should support higher demand for our apartments; and

• An attractive quality of life, which may lead to higher demand and retention for our apartments and allow us to more readily increase rents.

1

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 currently 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, cash flows generated from operations, draws on our unsecured credit facility or other short-term borrowing, the use of debt and equity offerings under our automatic shelf registration statement, proceeds from property dispositions, equity issued from our 2017 at-the-market ("ATM") share offering program, other unsecured borrowings, or secured mortgages.

Sophisticated Property Management. We believe the depth of our organization enables us to deliver quality services, promote resident satisfaction, and retain residents, thereby increasing our operating revenues and reducing our operating expenses. We manage our properties utilizing a staff of professionals and support personnel, including certified property managers, experienced apartment managers and leasing agents, and trained apartment maintenance technicians. Our on-site personnel are trained to deliver high-quality services to our residents, and we strive to motivate our on-site employees through incentive compensation arrangements based upon property operational results, rental rate increases, occupancy levels, and level of new leases and lease renewals achieved.

Operations. We believe an intense focus on operations is necessary to realize consistent, sustained earnings growth. Ensuring resident satisfaction, increasing rents as market conditions allow, maximizing rent collections, maintaining property occupancy at optimal levels, and controlling operating costs comprise our principal strategies to maximize property financial results. We believe our web-based property management and revenue management systems strengthen on-site operations and allow us to quickly adjust rental rates as local market conditions change. Lease terms are generally staggered based on vacancy exposure by apartment type so lease expirations are matched to each property's seasonal rental patterns. We generally offer leases ranging from six to eighteen months with individual property marketing plans structured to respond to local market conditions. In addition, we conduct ongoing customer service surveys to help ensure timely response to residents' changing needs and a high level of satisfaction.

Investments in Joint Ventures. We have entered into, and may continue in the future to enter into, joint ventures or partnerships, including limited liability companies, through which we own an indirect economic interest in less than 100% of the community or land owned by the joint venture or partnership. We currently have three discretionary investment Funds (the “Funds”), two of which are closed to future investments, and the third of which we formed in March 2015 for future multifamily investments of up to $450 million. See Note 8, “Investments in Joint Ventures,” and Note 14, “Commitments and Contingencies,” in the notes to Consolidated Financial Statements for further discussion of our investments in joint ventures.

Competition

There are numerous housing alternatives which compete with our communities in attracting residents. Our properties compete directly with other multifamily properties as well as condominiums, single-family homes, third-party providers of short-term rentals and serviced apartments, which are available for rent or purchase in the markets in which our communities are located. This competitive environment could have a material adverse effect on our ability to lease apartment homes at our present properties or any newly developed or acquired property, as well as on the rents realized.

Employees

At December 31, 2017, we had approximately 1,600 employees, including executive, administrative, and community personnel.

Qualification as a Real Estate Investment Trust

As of December 31, 2017, we met the qualification of a REIT under Sections 856-860 of the Internal Revenue Code of 1986, as amended (the “Code”). As a result, we, with the exception of our taxable REIT subsidiaries, will not be subject to federal income tax to the extent we continue to meet certain requirements of the Code.

Item 1A. Risk Factors

In addition to the other information contained in this Form 10-K, the following risk factors should be considered carefully in evaluating our business. Our business, financial condition, or results of operations could be materially adversely affected by any of these risks.

2

Risks Associated with Capital Markets, Credit Markets, and Real Estate

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.

The capital and credit markets are subject to volatility and disruption. We therefore may not be able to obtain new debt financing or refinance our existing debt on favorable terms or at all, which would adversely affect our liquidity, our ability to make distributions to shareholders, acquire assets and continue our development activities. Other weakened economic conditions, including job losses, high unemployment levels, stock market volatility, and uncertainty about the future, could adversely affect rental rates and occupancy levels. Unfavorable changes in economic conditions may have a material adverse impact on our cash flows and operating results.

Additional key economic risks which may adversely affect conditions in the markets in which we operate include the following:

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

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

• declines in market rental rates;

• low mortgage interest rates and home pricing, making alternative housing more affordable;

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

• regional economic downturns, including, but not limited to, business layoffs, downsizing and increased unemployment, which may impact one or more of our geographical markets; and

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

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

Our apartment leases are generally for a term of eighteen months or less. As these leases typically permit the residents to leave at the end of the lease term without penalty, our rental revenues are impacted by declines in market rents more quickly than if our leases were for longer terms.

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

There are numerous housing alternatives which compete with our properties in attracting residents. Our properties compete directly with other multifamily properties, condominiums, single-family homes, third-party providers of short-term rentals and serviced apartments, which are available for rent or purchase in the markets in which our properties are located. This competitive environment could have a material adverse effect on our ability to lease apartment homes at our present properties or any newly developed or acquired property, as well as on the rents realized.

We face risks associated with land holdings and related activities.

We hold land for future development and may in the future acquire additional land holdings. The risks inherent in purchasing, owning, and developing land increase as demand for apartments, or rental rates, decrease. Real estate markets are highly uncertain and, as a result, the value of undeveloped land may fluctuate significantly. In addition, carrying costs can be significant and can result in losses or reduced profitability. As a result, we hold certain land, and may in the future acquire additional land, in our development pipeline at a cost we may not be able to fully recover or at a cost which may preclude us from developing a profitable multifamily community. If there are subsequent changes in the fair market value of our land holdings which we determine is less than the carrying basis of our land holdings reflected in our financial statements plus estimated costs to sell, we may be required to take future impairment charges which would reduce our net income.

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

There is significant uncertainty surrounding the futures of Fannie Mae and Freddie Mac. Through their lender originator networks, Fannie Mae and Freddie Mac are significant lenders both to us and to buyers of our properties. Fannie Mae and Freddie Mac have a mandate to support multifamily housing through their financing activities and any changes to their mandates, further reductions in their size or the scale of their activities, or loss of their key personnel could have a significant adverse impact on us and may, among other things, lead to lower values for our assets and higher interest rates on our

3

borrowings. Fannie Mae's and Freddie Mac's regulator has set overall volume limits on most of Fannie Mae's and Freddie Mac's lending activities. The regulator in the future could require Fannie Mae and Freddie Mac to focus more of their lending activities on small borrowers or properties the regulator deems affordable, which may or may not include our assets, which could also adversely impact us. In addition, the members of the current Presidential administration and House and Senate banking committees have announced the reform of Fannie Mae and Freddie Mac is a priority, and there is uncertainty regarding the impact of these actions on us and buyers of our properties.

Risks Associated with Our Operations

Development, redevelopment and construction risks could impact our profitability.

We intend to continue to develop, redevelop and construct multifamily apartment communities for our portfolio. In 2018, we expect to incur costs between approximately $140 million and $160 million related to the construction of seven consolidated projects. Additionally, during 2018, we expect to incur costs between approximately $45 million and $55 million related to the start of new development activities, between approximately $37 million and $41 million related to repositions and revenue enhancing expenditures of existing properties and between approximately $28 million and $32 million in extensive redevelopment expenditures of existing properties. Our development, redevelopment and construction activities may be exposed to a number of risks which may increase our construction costs and decrease our profitability, including the following:

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

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

• inability to obtain financing with favorable terms;

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

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

• the incurrence of costs related to the abandonment of development opportunities which we have pursued and subsequently deemed unfeasible.

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

One of our wholly-owned subsidiaries is engaged in the business of providing general contracting services under construction contracts entered into between it and third parties (which may include our nonconsolidated affiliates). The terms of those construction contracts generally require this subsidiary to estimate the time and costs to complete a project to calculate the cost plus margin for the project fee, but not to exceed a maximum amount, and to assume the risk when these estimates may be greater than anticipated. As a result, profitability on those contracts is dependent on the ability to accurately predict such factors. The time and costs necessary to complete a project may be affected by a variety of factors, including, but not limited to, those listed above, many of which are beyond this subsidiary’s control. In addition, the terms of those contracts generally require this subsidiary to warrant its work for a period of time during which it may be required to repair, replace, or rebuild non-conforming work. Further, trailing liabilities, based on various legal theories such as claims of negligent construction, may result from such projects, and these trailing liabilities may go on for a number of years depending on the length of the statute of repose in the applicable jurisdictions.

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

We have invested and may continue to invest as a joint venture partner in joint ventures. These investments involve risks, including, but not limited to, the possibility the other joint venture partner may: have business goals which are inconsistent with ours, possess the ability to take or force action or withhold consent contrary to our requests, or become insolvent and require us to assume and fulfill the joint venture’s financial obligations. We and our joint venture partners may each have the right to initiate a buy-sell arrangement, which could cause us to sell our interest, or acquire a joint venture partner’s interest, at a time when we otherwise would not have entered into such a transaction. Each joint venture agreement is individually negotiated, and our ability to operate, finance, or dispose of a community in our sole discretion may be limited to varying degrees depending on the terms of the applicable joint venture agreement. The risks associated with our discretionary Funds, which we manage as the general partner and advisor, include, but are not limited to, the following:

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

4

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

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

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

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

Competition could adversely affect our ability to acquire properties.

We expect other real estate investors, including insurance companies, pension and investment funds, private investors, and other multifamily REITs, will compete with us to acquire additional operating properties. This competition could increase prices for the type of properties we would likely pursue and adversely affect our ability to acquire these properties or achieve the expected profitability of such properties upon acquisition.

Our acquisition strategy may not produce the cash flows expected.

We may acquire additional operating properties on a selective basis. Our acquisition activities are subject to a number of risks, including, but not limited to, the following:

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

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

• the expected occupancy, rental rates and operating expenses may differ from the actual results;

• we may not be able to obtain adequate financing; and

• we may not be able to identify suitable candidates on terms acceptable to us and may not achieve expected returns or other benefits as a result of integration challenges, such as personnel and technology.

Failure to qualify as a REIT could have adverse consequences.

We may not continue to qualify as a REIT in the future. Also, the Internal Revenue Service may challenge our qualification as a REIT for prior years.

For any taxable year we fail to qualify as a REIT and do not qualify under statutory relief provisions:

• we would be subject to federal income tax on our taxable income at regular corporate rates including, for taxable years ended before January 1, 2018, any applicable alternative minimum tax;

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

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

We may face other tax liabilities in the future which may impact our cash flow. These potential tax liabilities may be calculated on our income or property values at either the corporate or individual property levels. Any additional tax expense incurred would decrease the cash available for cash distributions to our common shareholders and non-controlling interest holders. Additionally, 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.

Tax laws have recently changed and may continue to change at any time, and any such legislative or other actions could have a negative effect on us.

The 2017 Tax Act was signed into law on December 22, 2017. The law includes significant changes to the U.S. corporate income tax system, including a Federal corporate rate reduction from 35% to 21% for non-REIT "C" corporations, which may cause investors to perceive investments in REITs to be less attractive than investments in the stock of non-REIT "C" corporations. The law also includes limitations on the deductibility of executive compensation, which may result in our being

5

required to pay higher dividends to continue to qualify as a REIT at a time and in an amount that otherwise may not be in the best interest for us or our shareholders.

In addition, tax laws remain under constant review by persons involved in the legislative process, at the Internal Revenue Service and the U.S. Department of Treasury, and by various state and local tax authorities. Changes to tax laws, regulations, or administrative interpretations, which may be applied retroactively could adversely affect us in a number of additional ways, including making it more difficult or more costly for us to qualify as a REIT or decreasing real estate values generally.

We cannot predict the full impact of the 2017 Tax Act or whether, when, in what forms, or with what effective dates the tax laws, regulations and administrative interpretations applicable to us or our shareholders may be further changed. Any of these matters may significantly affect our liquidity and results of operations, as well as the value of our shares.

Litigation risks could affect our business.

As a publicly-traded owner, manager and developer of multifamily properties, we may incur liability based on various conditions at our properties and the buildings thereon, and we also have become and in the future may become involved in legal proceedings, including consumer, employment, tort or commercial litigation, which if decided adversely to or settled by us, and not adequately covered by insurance, could result in liability which is material to our financial condition or results of operations.

Damage from catastrophic weather and other natural events could result in losses.

A certain number of our properties are located in areas that have experienced and may in the future experience catastrophic weather and other natural events from time to time, including fires, snow or ice storms, windstorms, tornadoes, hurricanes, earthquakes, flooding or other severe weather. These adverse weather or natural events could cause substantial damages or losses to our properties which could exceed our insurance coverage. In the event of a loss in excess of insured limits, we could lose our capital invested in the affected property, anticipated future revenue from the property, and could also continue to be obligated to repay any mortgage indebtedness or other obligations related to the property. Any such loss could materially and adversely affect our business, financial condition and results of operations.

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

We use technology in substantially all aspects of our business operations. We also use mobile devices, social networking, outside vendors and other online activities to connect with our employees, suppliers and residents. Such uses and the on-going advancement in technology give rise to potential cybersecurity risks with increasing sophistication, including but not limited to, security breach, espionage, system disruption, theft and inadvertent release of confidential information. Our business involves the storage and transmission of numerous classes of sensitive and confidential information and intellectual property, including residents' and suppliers' personal information, private information about employees, and financial and strategic information about us. Further, as we pursue our strategy to grow through acquisitions and developments and to pursue new initiatives to improve our operations, we are also expanding our information technologies, resulting in a larger technological presence and corresponding exposure to cybersecurity risk. If we fail to assess and identify cybersecurity risks associated with our operations, we may become increasingly vulnerable to such risks and may be liable for the consequential litigation and remediation costs. Additionally, the measures we have implemented to prevent security breaches and cyber incidents may not be effective and there can be no complete assurance of prevention or anticipation of such incidents. The theft, destruction, loss, misappropriation, or release of sensitive data, confidential information or intellectual property, or interference with our information technology systems or the technology systems of third parties on which we rely could result in business disruption, negative publicity, brand damage, violation of privacy laws, loss of residents, potential liability and competitive disadvantage, any of which could result in a material adverse effect on our financial condition or results of operations.

Our third-party service providers are primarily responsible for the security of their own information technology environments and in certain instances, we rely significantly on third-party service providers to supply and store our sensitive data in a secure manner. All of these third parties face potential risks relating to cybersecurity similar to ours which could disrupt their businesses and therefore adversely impact us. While we provide guidance and specific requirements in some cases, we do not directly control any of these parties' information technology security operations, or the amount of investment they place in guarding against cybersecurity threats. Accordingly, we are subject to any flaws in or breaches to their information technology systems or those which they operate for us, which could have a material adverse effect on our financial condition or results of operations.

6

Risks Associated with Our Indebtedness and Financing

We have significant debt, which could have adverse consequences.

As of December 31, 2017, we had outstanding debt of approximately $2.2 billion. This indebtedness could have adverse consequences, including, but not limited to, the following:

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

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

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

The mortgages on our properties subject to secured debt, our unsecured credit facilities, and the indenture under which our unsecured debt was issued, contain customary restrictions, requirements, and other limitations, as well as certain financial and operating covenants including maintenance of certain financial ratios. Maintaining compliance with these provisions could limit our financial flexibility. A default in these provisions, if uncured, could require us to repay the indebtedness before the scheduled maturity date, which could adversely affect our liquidity and increase our financing costs.

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

Substantially all of our income is derived from rental and other income from our multifamily communities. As a result, our performance depends in large part on our ability to collect rent from residents, which could be negatively affected by a number of factors, including, but not limited to, the following:

• delay in resident lease commencements;

• decline in occupancy;

• failure of residents to make rental payments when due;

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

• our ability to adequately manage and maintain our communities;

• competition from other available apartments and housing alternatives;

• changes in market rents; and

• increases in operating expenses.

Cash flow could be insufficient to meet required payments of principal and interest with respect to debt financing. In order for us to continue to qualify as a REIT we must meet a number of organizational and operational requirements, including a requirement to distribute annual dividends to our shareholders equal to a minimum of 90% of our adjusted taxable income. This requirement limits the cash available to meet required principal payments on our debt.

Issuances of additional debt may adversely impact our financial condition.

Our capital requirements depend on numerous factors, including the rental and occupancy rates of our multifamily properties, minimum dividend requirements to our equity holders, development, redevelopment and other capital expenditures, costs of operations, and potential acquisitions. If our capital requirements vary materially from our plans, we may require additional financing earlier than anticipated. If we issue more debt, we could become more leveraged, resulting in increased risk of default on our obligations and an increase in our debt service requirements, both of which could adversely affect our financial condition and ability to access debt and equity capital markets in the future.

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

We are subject to the risk indebtedness on our properties or our unsecured indebtedness will not be renewed, repaid, or refinanced when due or the terms of any renewal or refinancing will not be as favorable as the existing terms of such indebtedness. If we are unable to refinance our indebtedness on acceptable terms, or at all, we might be forced to dispose of one or more of the properties on disadvantageous terms, which might result in losses to us. Such losses could have a material adverse effect on us and our ability to pay amounts due on our debt and make distributions to our shareholders. Furthermore, if a property is mortgaged to secure payment of indebtedness and we are unable to meet mortgage payments, the mortgagee could foreclose on the property, appoint a receiver and exercise rights under an assignment of rents and leases, or pursue other

7

remedies, all with a consequent loss of our revenues and asset value. Foreclosures could also create taxable income without accompanying cash proceeds, thereby hindering our ability to meet the REIT distribution requirements of the Code.

We may be adversely affected by changes in LIBOR reporting practices or the method in which LIBOR is determined.

Our unsecured credit facilities and fair value of derivative instruments are indexed to the London Interbank Offered Rate ("LIBOR"). On July 27, 2017, the Financial Conduct Authority (the "FCA") announced its intention to phase out LIBOR rates by the end of 2021. It is not possible to predict the further effect of the rules of the FCA, any changes in the methods by which LIBOR is determined, or any other reforms to LIBOR which may be enacted in the United Kingdom, the European Union or elsewhere. Any such developments may cause LIBOR to perform differently than in the past, or cease to exist. In addition, any other legal or regulatory changes made by the FCA, ICE Benchmark Administration Limited, the European Money Markets Institute (formerly Euribor-EBF), the European Commission or any other successor governance or oversight body, or future changes adopted by such body, in the method by which LIBOR is determined or the transition from LIBOR to a successor benchmark may result in, among other things, a sudden or prolonged increase or decrease in LIBOR, a delay in the publication of LIBOR, trigger changes in the rules or methodologies in LIBOR discouraging market participants from continuing to administer or to participate in LIBOR's determination, and, in certain situations, could result in LIBOR no longer being determined and published. If a published U.S. dollar LIBOR rate is unavailable after 2021, the interest rates on our debt which is indexed to LIBOR will be determined using various alternative methods, any of which may result in interest obligations which are more than or do not otherwise correlate over time with the payments that would have been made on such debt if U.S. dollar LIBOR was available in its current form. Further, the same costs and risks which may lead to the discontinuation or unavailability of U.S. dollar LIBOR may make one or more of the alternative methods impossible or impracticable to determine. Any of these proposals or consequences could have a material adverse effect on our financing costs.

Rising interest rates could both increase our borrowing costs, thereby adversely affecting our cash flows and the amounts available for distribution to our shareholders, and decrease our share price, if investors seek higher yields through other investments.

We have mortgage debt with varying interest rates dependent upon various market indexes. In addition, we have an unsecured credit facility bearing interest at variable rates on all amounts drawn. We may incur additional variable rate debt in the future. Increases in interest rates would increase our interest expense, unless we make arrangements which hedge the risk of rising interest rates, and would increase the costs of refinancing existing debt and of issuing new debt. Accordingly, higher interest rates would adversely affect cash flow, net income, and cash available for payment of our debt obligations and distributions to shareholders.

An environment of rising interest rates could also lead holders of our securities to seek higher yields through other investments, which could adversely affect the market price of our shares. One of the factors which may influence the price of our stock in public markets is the annual distribution rate we pay as compared with the yields on alternative investments.

Failure to hedge effectively against interest rates may adversely affect results of operations.

From time-to-time, we may seek to manage our exposure to interest rate volatility by using interest rate hedging arrangements for debt instruments and future debt issuances. These agreements involve risks, such as the risk the counterparties may fail to honor their obligations under these arrangements, and these arrangements may not be effective in reducing our exposure to interest rate changes. Failure to hedge effectively against interest rate changes could have a material adverse effect on us and our ability to make distributions to our shareholders and pay amounts due on our debt.

Failure to maintain our current credit ratings could adversely affect our cost of funds, related margins, liquidity, and access to capital markets.

Moody’s, Fitch, and Standard & Poor's, the major debt rating agencies, routinely evaluate our debt and have given us ratings of A3 with stable outlook, A- with stable outlook, and BBB+ with stable outlook, respectively, on our senior unsecured debt. These ratings are based on a number of factors, which include their assessment of our financial strength, liquidity, capital structure, asset quality, and sustainability of cash flow and earnings. Due to changes in market conditions, we may not be able to maintain our current credit ratings, which could adversely affect our cost of funds and related margins, liquidity, and access to capital markets.

Risks Associated with Our Shares

Share ownership limits and our ability to issue additional equity securities may prevent takeovers beneficial to shareholders.

For us to maintain our qualification as a REIT, we must have 100 or more shareholders during the year and not more than 50% in value of our outstanding shares may be owned, directly or indirectly, by five or fewer individuals. As defined for federal

8

income tax purposes, the term “individuals” includes a number of specified entities. To minimize the possibility of us failing to qualify as a REIT under this test, our declaration of trust includes restrictions on transfers of our shares and ownership limits. The ownership limits, as well as our ability to issue other classes of equity securities, may delay, defer, or prevent a change in control. These provisions may also deter tender offers for our common shares which may be attractive to you or limit your opportunity to receive a premium for your shares which might otherwise exist if a third party were attempting to effect a change in control transaction.

Our share price will fluctuate.

The market price and trading volume of our common shares are subject to fluctuation due to general market conditions, the risks discussed in this report and other matters, including, but not limited to, the following:

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

• investor interest in our property portfolio;

• the reputation and performance of REITs;

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

• the results of our financial condition and operations;

• the perception of our growth and earnings potential;

• minimum dividend requirements;

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

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

The form, timing and amount of dividend distributions in future periods may vary and be impacted by economic and other considerations.

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

In the first quarter of 2018, the Company's Board of Trust Managers declared a first quarter dividend of $0.77 per common share to our common shareholders of record as of March 30, 2018. Future dividend payments are paid at the discretion of the Board of Trust Managers and depend on cash flows generated from operations, the Company's financial condition and capital requirements, distribution requirements under the REIT provisions of the Code and other factors which may be deemed relevant by our Board of Trust Managers. Assuming similar dividend distributions for the remainder of 2018, our annualized dividend rate for 2018 would be $3.08.

In September 2016, 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 of gains on dispositions of assets completed in 2016. The special dividend was in addition to our quarterly dividend of $0.75 per common share. We also paid equivalent amounts per unit to holders of the common operating partnership units.

As of February 8, 2018, there were approximately 387 shareholders of record and approximately 34,624 beneficial owners of our common shares.

In May 2017, we created an at-the market ("ATM") share offering program through which we can, but have no obligation to, sell common shares having an aggregate offering price of up to $315.3 million (the "2017 ATM program"), in amounts and at times as we determine, into the existing trading market at current market prices as well as through negotiated transactions. Actual sales from time to time may depend on a variety of factors including, among others, market conditions, the trading price of our common shares, and determinations by management of the appropriate sources of funding for us. During the year ended December 31, 2017, we issued approximately 28.1 thousand common shares under the 2017 ATM program at our average price of $90.44 per share for a total net consideration of approximately $2.5 million. The proceeds from the sale of our common shares under the 2017 ATM program are intended to be used for general corporate purposes, which may include reducing future borrowings under our $600 million unsecured line of credit, the repayment of other indebtedness, the redemption or other repurchase of outstanding debt or equity securities, funding for development activities, and financing for acquisitions.

As of the date of this filing, we had common shares having an aggregate offering price of up to $312.8 million remaining available for sale under the 2017 ATM program. No additional shares were sold under the 2017 ATM program subsequent to December 31, 2017 through the date of this filing.

17

In November 2014, we created an ATM share offering program through which we could, but had no obligation to, sell common shares having an aggregate offering price of up to $331.3 million (the "2014 ATM program"). Concurrently with the creation of the 2017 ATM program in May 2017 discussed above, we terminated the 2014 ATM program and rolled the $315.3 million remaining available for sale under the 2014 ATM program into the 2017 ATM program. Upon its termination, no further common shares were available for sale under the 2014 ATM program.

See Part III, Item 12, for a description of securities authorized for issuance under equity compensation plans.

We have a repurchase plan approved by our Board of Trust Managers which allows for the repurchase of up to $500 million of our common equity securities through open market purchases, block purchases, and privately negotiated transactions. As of the date of this filing, the remaining dollar value of our common equity securities authorized to be repurchased under this program was approximately $269.8 million. There were no repurchases under this program for the years ended December 31, 2017, 2016, or 2015.

(c) Includes operating properties held for sale at net book value and excludes discontinued operating properties and joint ventures for all periods presented.

(d) Management considers Funds from Operations (“FFO”) and adjusted FFO ("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 accounting principles generally accepted in the United States of America (“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 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. See "Funds from Operations and Adjusted FFO" in Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" for reconciliations of net income attributable to common shareholders to FFO and AFFO.

(e) Includes operating properties held for sale and discontinued operating properties held for sale for all periods presented.

(f) Excludes apartment homes owned in joint ventures.

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

The following discussion should be read in conjunction with the consolidated financial statements and notes appearing elsewhere in this report. Historical results and trends which might appear in the consolidated financial statements should not be interpreted as being indicative of future operations.

We consider portions of this report to be “forward-looking” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, both as amended, with respect to our expectations for future periods. Forward-looking statements do not discuss historical fact, but instead include statements related to expectations, projections, intentions, or other items relating to the future; forward-looking statements are not guarantees of future performance, results, or events. Although we believe the expectations reflected in our forward-looking statements are based upon reasonable assumptions, we can give no assurance our expectations will be achieved. Any statements contained herein which are not statements of historical fact should be deemed forward-looking statements. Reliance should not be placed on these forward-looking statements as 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;

• Failure to qualify as a REIT could have adverse consequences;

• Tax laws have recently changed and may continue to change at any time, and any such legislative or other actions could have a negative effect on us;

• Litigation risks could affect our business;

• Damage from catastrophic weather and other natural events could result in losses;

• 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;

• We may be adversely affected by changes in LIBOR reporting practices or the method in which LIBOR is determined;

• Rising interest rates could both increase our borrowing costs, thereby adversely affecting our cash flows and the amounts available for distribution to our shareholders, and decrease our share price, if investors seek higher yields through other investments;

• Failure to hedge effectively against interest rates may adversely affect results of operations;

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

21

• 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. Overall, we focus on investing in markets characterized by high-growth economic conditions, strong employment, and attractive quality of life which we believe leads to higher demand and retention of our apartments. As of December 31, 2017, we owned interests in, operated, or were developing 162 multifamily properties comprised of 55,143 apartment homes across the United States as detailed in the following Property Portfolio table. In addition, we own other land holdings which we may develop into multifamily apartment communities in the future.

Property Operations

Our results for the year ended December 31, 2017 reflect an increase in same store revenues of 2.9% as compared to 2016. These increases were due to higher average rental rates and increased other property income, which we believe was primarily attributable to improving job growth, favorable demographics, a manageable supply of new multifamily housing, and in part to more individuals choosing to rent versus buy as evidenced by the continued low level of homeownership rates, all of which have resulted in higher rental rates. We also believe the continued low levels of homeownership rates are mainly attributable to difficulties in obtaining mortgage loans as well as changing demographic trends, both of which promote apartment rentals. We also believe U.S. economic and employment growth is likely to continue during 2018 and the supply of new multifamily homes will likely remain at manageable levels. If economic conditions were to worsen, our operating results could be adversely affected.

Construction Activity

At December 31, 2017, we had seven projects under construction comprised of 2,110 apartment homes, with stabilization expected to be completed within the next 39 months. As of December 31, 2017, we estimate the additional cost to complete the construction of the seven projects to be approximately $282.3 million.

Acquisitions

Operating properties: In June 2017, we purchased one operating property, Camden Buckhead Square, comprised of 250 apartment homes, located in Atlanta, Georgia for approximately $58.3 million. In January 2018, we acquired one operating property comprised of 358 apartment homes located in St. Petersburg for approximately $126.9 million. In February 2018, we acquired one operating property comprised of 333 apartment homes located in Orlando, Florida for approximately $81.4 million.

Land: In April 2017, we acquired approximately 8.2 acres of land in San Diego, California for $20.0 million.

Dispositions

In December 2017, we soldoneoperating property, comprised of1,005apartment homes, located in Corpus Christi, Texas for approximately$78.4 millionand recognized a gain of approximately$43.2 million.

Hurricanes

In August 2017, Hurricane Harvey impacted certain multifamily communities within our Texas portfolio. In September 2017, Hurricane Irma impacted certain multifamily communities throughout the state of Florida, and in the Atlanta, Georgia and Charlotte, North Carolina areas. We incurred approximately $3.9 million in expenses at our wholly-owned multifamily communities impacted by these hurricanes which is recorded in property operating and maintenance expenses, with no insurance recoveries anticipated. We also incurred approximately $0.7 million in other storm-related expenses relating to these hurricanes, which are recorded in general and administrative expenses. Additionally, we recognized $0.4 million, representing our share of ownership interest of hurricane-related expenses incurred by the multifamily communities of the Funds, which is recorded in equity in income of joint ventures.

22

Other

In September 2017, we issued approximately 4.8 million common shares in a public equity offering and received approximately $442.5 million in net proceeds. We also issued approximately 28,111 shares under our 2017 ATM program during the year ended December 31, 2017 and received approximately $2.5 million in net proceeds.

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 currently 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, cash flows generated from operations, draws on our unsecured credit facility or other short-term borrowing, the use of debt and equity offerings under our automatic shelf registration statement, proceeds from property dispositions, equity issued from our 2017 ATM program, other unsecured borrowings, or secured mortgages.

As of December 31, 2017, we had approximately $368.5 million in cash and cash equivalents, $586.6 million available under our $600.0 million unsecured credit facility and $45.0 million available under our $45.0 million unsecured short-term borrowing facility. 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 2017 ATM program. We believe scheduled payments of debt in 2018 are manageable at approximately $173.7 million which represents approximately 7.9% of our total outstanding debt, and includes amortization of debt discounts and debt issuance costs, net of scheduled principal payments of approximately $1.3 million. 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 years ended December 31 are as follows:

	2017			2016			2015
Average monthly property revenue per apartment home	$	1,625		$	1,556		$	1,479
Annualized total property expenses per apartment home (1)	$	7,114		$	6,634		$	6,392
Weighted average number of operating apartment homes owned 100%	46,210			46,934			47,088
Weighted average occupancy of operating apartment homes owned 100% (2)	95.4		%	95.3		%	95.7		%

(1) 2017 includes approximately $3.9 million of storm-related expenses relating to Hurricanes Harvey and Irma for the year ended December 31, 2017.

(2) Our one student housing community, which was sold in December 2017, 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 an 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, should not be considered an alternative to net cash from operating activities as a measure of liquidity, and should not be considered an indication of cash available to fund cash needs. Additionally, NOI as disclosed by other REITs may not be comparable to our calculation.

Same Store Analysis

Year ended December 2017 compared to year ended December 2016

Same store property NOI increased approximately $11.1 million for the year ended December 31, 2017 as compared to the same period in 2016. This increase was due to an increase of approximately $22.5 million in same store property revenues for the year ended December 31, 2017, partially offset by an increase of approximately $11.4 million in same store property expenses for the year ended December 31, 2017, as compared to the same period in 2016.

The $22.5 million increase in same store property revenue for the year ended December 31, 2017 as compared to the same period in 2016, was due in part to an increase in same store rental revenues of approximately $16.4 million for the year ended December 31, 2017, which was primarily due to a 2.9% increase in average rental rates for our same store portfolio for the year ended December 31, 2017, as compared to the same period in 2016. The increase in same store property revenue was also due to an increase of approximately $6.1 million in other property revenue for the year ended December 31, 2017 as compared to the same period in 2016, primarily due to increases in income from our bulk internet rebilling program and miscellaneous fee income.

30

The $11.4 million increase in same store property expense for the year ended December 31, 2017 as compared to the same period in 2016, was primarily due to increased costs of approximately $4.4 million associated with our bulk internet and other utility rebilling programs and a $3.9 million increase in real estate taxes as a result of higher property valuations at a number of our communities. These increases were also due to higher property insurance expenses of approximately $1.8 million during the year ended December 31, 2017 as compared to the same period in 2016.

Year ended December 2016 compared to year ended December 2015

Same store property NOI increased approximately $22.1 million for the year ended December 31, 2016 as compared to the same period in 2015. This increase was due to an increase of approximately $27.9 million in same store property revenues for the year ended December 31, 2016, partially offset by an increase of approximately $5.8 million in same store property expenses for the year ended December 31, 2016, as compared to the same period in 2015.

The $27.9 million increase in same store property revenue for the year ended December 31, 2016 as compared to the same period in 2015, was due in part to an increase in same store rental revenues of approximately $17.4 million for the year ended December 31, 2016, which was primarily due to a 3.2% increase in average rental rates for our same store portfolio for the year ended December 31, 2016, as compared to the same period in 2015. The increase in same store property revenue was also due to an increase of approximately $10.5 million in other property revenue for the year ended December 31, 2016 as compared to the same period in 2015, primarily due to increases in income from our bulk internet rebilling program and miscellaneous fee income.

The $5.8 million increase in same store property expense for the year ended December 31, 2016 as compared to the same period in 2015, was primarily due to increased costs of approximately $5.5 million associated with our bulk internet and other utility rebilling programs and a $2.5 million increase in real estate taxes as a result of higher property valuations at a number of our communities. These increases were partially offset by decreased property insurance expenses of approximately $3.0 million during the year ended December 31, 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 $21.0 million for the year ended December 31, 2017 as compared to the same period in 2016. The increase was due to an increase of approximately $33.5 million in revenues for the year ended December 31, 2017, partially offset by an increase of approximately $12.5 million in expenses for the year ended December 31, 2017, as compared to the same period in 2016. The increases in property revenues and expenses from our non-same store communities were primarily due to the stabilization of four operating properties in 2016 and four operating properties in 2017 and the acquisition of one operating property in 2017. The increases in property revenues and expenses from our development and lease-up communities were primarily due to the timing of completion and partial lease up of one property during 2016 and 2017, and the partial lease-up of one property which was under construction at December 31, 2017.

Property NOI from non-same store and development and lease-up communities increased approximately $21.2 million for the year ended December 31, 2016 as compared to the same period in 2015. The increase was due to an increase of approximately $33.3 million in revenues for the year ended December 31, 2016, partially offset by an increase of approximately $12.1 million in expenses for the year ended December 31, 2016, as compared to the same period 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 in 2015 and four operating properties in 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 three properties during 2015 and two properties during 2016, and the partial lease-up of two properties which was under construction at December 31, 2016.

Hurricane Expenses

We incurred approximately $3.9 million of expenses at our wholly-owned multifamily communities impacted by Hurricanes Harvey and Irma in August and September 2017, respectively, with no insurance recoveries anticipated, during the year ended December 31, 2017.

Dispositions/Other Property Analysis

Dispositions/other property NOI decreased approximately $21.1 million for the year ended December 31, 2017 as compared to the same period in 2016. The decrease was primarily due to the disposition of one dual-phased operating property and six other operating properties in 2016 and the disposition of one operating property in 2017.

Dispositions/other property NOI decreased approximately $12.8 million for the year ended December 31, 2016 as compared to the same period in 2015. The decrease was primarily due to the disposition of three operating properties in 2015, and the disposition of one dual-phase operating property and six other operating properties in 2016.

Fee and asset management income, which represents income related to property management of our joint ventures and fees from third-party construction projects, increased approximately $1.3 million for the year ended December 31, 2017 as compared to 2016 and decreased approximately $0.1 million for the year ended December 31, 2016 as compared to 2015. The increase for 2017 as compared to 2016 was primarily due to an increase in higher third-party construction activity and higher fees earned on capital projects at Fund communities. The slight decrease for 2016 as compared to 2015 was primarily due to a

32

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, partially offset by higher third-party construction activity.

Interest and other income increased approximately $0.8 million for the year ended December 31, 2017, as compared to 2016, and increased approximately $1.6 million for the year ended December 31, 2016 as compared to 2015. The increase for the year ended December 31, 2017 was primarily due to higher interest income earned on investments in cash and cash equivalents due to maintaining higher average cash balances throughout the year ended December 31, 2017, as compared to the same period in 2016. The increase for 2016 was 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 interest income earned due to higher average note receivable balances outstanding on our real estate secured loans to unaffiliated third parties in 2016, as compared to the same period in 2015.

Our deferred compensation plans recognized income of approximately $16.6 million in 2017, income of approximately $5.5 million in 2016 and a loss of approximately $0.3 million in 2015. 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. The increase in 2017 as compared to 2016 was also due to higher diversification of participants' fully vested share awards into other equity securities in 2016 and 2017.

Property management expenses, which primarily represent regional supervision and accounting costs related to property operations, increased approximately $0.6 million for the year ended December 31, 2017 as compared to 2016 and increased approximately $2.1 million for the year ended December 31, 2016 as compared to 2015. The increase for 2017 as compared to 2016 was primarily related to higher salary and benefit costs, higher professional expenses and higher education programs provided to our regional employees. The increase for 2016 as compared to 2015 was primarily due to increases in salaries, benefits and incentive compensation expenses. Property management expenses were 2.9% of total property revenues for each of the years ended December 31, 2017 and 2016, and were 2.8% of total property revenues for the year ended December 31, 2015.

Fee and asset management expense, which represents expenses related to property management of our joint ventures and fees from third-party construction projects, increased approximately $0.1 million for the year ended December 31, 2017 as compared to 2016 and decreased approximately $0.9 million for the year ended December 31, 2016 as compared to 2015. The slight increase for 2017 as compared to 2016 was primarily due to higher expenses relating to an increase in third-party construction activity in 2017 as compared to 2016. The decrease for 2016 as compared to 2015 was 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 was partially offset by higher expenses relating to an increase in third-party construction activity in 2016 as compared to 2015.

General and administrative expenses increased approximately $3.2 million during the year ended December 31, 2017 as compared to 2016 and increased approximately $1.2 million during the year ended December 31, 2016 as compared to 2015. General and administrative expenses were 5.5%, 5.4% and 5.5% of total revenues, excluding income (loss) on deferred

33

compensation plans, for the years ended December 31, 2017, 2016 and 2015, respectively. The increase for the year ended December 31, 2017 as compared to 2016 was primarily due to higher salary and benefit costs, $0.7 million of storm-related expenses related to Hurricanes Harvey and Irma in August and September 2017, and higher professional expenses. The increase for the year ended December 31, 2016 as compared to 2015 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 Incentive Plan of Camden Property Trust, and an increase in the value of awards granted in 2016 as compared to the value of awards which vested during the same period in 2015.

Interest expense decreased approximately $6.4 million for the year ended December 31, 2017 as compared to 2016 and decreased approximately $4.2 million for the year ended December 31, 2016 as compared to 2015. The decrease in interest expense in 2017 as compared to 2016 was primarily due to the repayment of a $246.8 million, 5.83% senior unsecured note payable in May 2017. The decrease was partially offset by lower capitalized interest during the year ended December 31, 2017, resulting from lower average balances in our development pipeline.

The decrease in interest expense in 2016 as compared to 2015 was primarily due to the repayment of a $250.0 million, 5.08% senior unsecured note payable in June 2015. The decrease was partially offset by lower capitalized interest during the year ended December 31, 2016, resulting from lower average balances in our development pipeline, and higher interest expense recognized on our variable rate debt due to higher weighted average interest rates in 2016 as compared to the same period in 2015.

Depreciation and amortization expense increased approximately $13.8 million for the year ended December 31, 2017 as compared to 2016 and increased approximately $9.2 million for the year ended December 31, 2016 as compared to 2015. The increase in 2017 as compared to 2016 was primarily due to the completion of units in our development pipeline, the acquisition of one operating property in 2017, the completion of repositions, and increases in capital improvements placed in service during 2017 and 2016. The increase was partially offset by a decrease in depreciation expense related to the disposition of one dual-phased operating property and six other operating properties in 2016, and one operating property in 2017.

The increase in depreciation and amortization expense in 2016 as compared to 2015 was 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. The increase was partially offset by a decrease in depreciation expense related to the disposition of one operating property during the fourth quarter of 2015, and the dispositions of one dual-phased operating property and six other operating properties in 2016.

Our deferred compensation plans incurred an expense of approximately $16.6 million in 2017, an expense of approximately $5.5 million in 2016 and a benefit of approximately $0.3 million in 2015. 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. The increase in 2017 as compared to 2016 was also due to higher diversification of participants' fully vested share awards into other equity securities in 2016 and 2017.

The $0.3 million loss on early retirement of debt during the year ended December 31, 2017 related to the early retirement of our $30.7 million tax-exempt secured note payable which was scheduled to mature in 2028. The loss on early retirement of debt primarily includes the applicable unamortized loan costs.

In 2017, we recognized a gain of approximately $43.2 million related to the sale of one operating property, which compares to an approximate $294.9 million gain recognized in 2016 related to the sale of one dual-phased property and six other operating properties, and an approximate $104.0 million gain recognized in 2015 related to the sale of three operating properties. For the year ended 2016, we also sold 6.3 acres of land adjacent to an operating property in Tampa, Florida for a gain of approximately $0.4 million and for the year ended 2015, we also sold two land holdings adjacent to operating properties in Dallas and Houston, Texas for a gain of approximately $0.3 million.

34

Equity in income of joint ventures decreased approximately $0.3 million for the year ended December 31, 2017 as compared to 2016, and increased approximately $1.0 million for the year ended December 31, 2016 as compared to 2015. The decrease in 2017 was primarily due to the recognition of approximately $0.4 million of expenses, representing our share of ownership interest of hurricane-related expenses incurred by the Fund multifamily communities due to Hurricanes Harvey and Irma in August and September 2017. The decrease in 2017 was also due to higher interest expense recognized by three operating properties owned by the Funds which refinanced existing variable construction loans into permanent financing arrangements at higher rates. These decreases were partially offset by an increase in earnings resulting from higher rental and other property revenues from the operating properties owned by the Funds.

The increase in equity in income in 2016 as compared to 2015 was primarily due to an increase 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 one of the Funds during the first quarter of 2016. The increase was partially offset by higher real estate taxes as a result of increased property valuations at a number of the communities owned by the Funds. The increase was further offset by an increase in interest expense incurred during the year ended December 31, 2016 resulting from interest capitalized during the year ended December 31, 2015 while an operating property was under construction.

Income tax expense decreased approximately $0.4 million for the year ended December 31, 2017, as compared to 2016, and decreased approximately $0.3 million for the year ended December 31, 2016, as compared to 2015. The decrease in 2017 was primarily due to an approximate $0.5 million state income tax refund received in 2017, partially offset by an increase in taxable income related to our third party construction activities conducted in a taxable REIT subsidiary. The decrease in 2016 was primarily due to lower state tax rates in 2016 as compared to 2015, partially offset by an increase in taxable income related to our third party construction activities conducted in a taxable REIT subsidiary.

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 the sale of previously depreciated operating properties, real estate depreciation and amortization, impairments of depreciable assets, and adjustments for unconsolidated joint ventures to reflect FFO on the same basis. 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 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.

Reconciliations of net income attributable to common shareholders to FFO and AFFO for the years ended December 31 are as follows:

Liquidity and Capital Resources

Financial Condition and Sources of Liquidity

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

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

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

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

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

Our interest expense coverage ratio, net of capitalized interest, was approximately 5.8, 5.5, and 5.2 times for the years ended December 31, 2017, 2016, and 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 80.0%, 78.3%, and 79.9% of our properties were unencumbered at December 31, 2017, 2016, and 2015, respectively. Our weighted average maturity of debt was approximately 4.3 years at December 31, 2017.

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

Our primary sources of liquidity are cash and cash equivalents on hand and cash flow generated from operations. Other sources may include one or more of the following: availability under our unsecured credit facility and other short-term borrowing, the use of debt and equity offerings under our automatic shelf registration statement, proceeds from property

36

dispositions, equity issued from our 2017 ATM program, and other unsecured borrowings or secured mortgages. We believe our liquidity and financial condition are sufficient to meet all of our reasonably anticipated cash needs during 2018 including:

• normal recurring operating expenses;

• current debt service requirements, including debt maturities;

• 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 cost of funds, and our ability to access capital markets.

Cash Flows

The following is a discussion of our cash flows for the years ended December 31, 2017 and 2016.

Net cash from operating activities was approximately $434.7 million during the year ended December 31, 2017 as compared to approximately $443.1 million during the year ended December 31, 2016. The decrease was primarily due to the disposition of 15 operating properties, a retail center, and approximately 19.6 acres of land classified as discontinued operations, and the disposition of one dual-phased operating property and six other operating properties during 2016 and one operating property during 2017. The decrease was also due to higher cash bonuses paid to employees in 2017 as compared to 2016. The decrease was partially offset by a 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 eight operating properties reaching stabilization during 2016 and 2017, the timing of completion and partial lease-up of one operating property during 2016 and 2017, the partial lease-up of one property which was under construction at December 31, 2017, and the acquisition of one operating property in 2017. See further discussions of our 2017 operations as compared to 2016 in "Results of Operations."

Net cash used in investing activities during the year ended December 31, 2017 totaled approximately $189.8 million as compared to net cash from investing activities of approximately $690.4 million during the year ended December 31, 2016. During 2017, we had cash outflows for property development and capital improvements of approximately $299.1 million. During 2017, we also acquired an operating property located in Atlanta, Georgia for approximately $58.3 million, and had increases of $2.0 million in a note receivable balance outstanding on a real estate secured loan to an unaffiliated third party. These outflows were partially offset by cash receipts of $100.0 million from the maturity of a short-term investment, and proceeds from the disposition of one operating property of $76.9 million. During 2016, we received approximately $623.0 million 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 from the sale of one dual-phase operating property and six other operating properties and one land holding. These cash inflows in 2016 were partially offset by cash outflows for property development and capital improvements of approximately $343.0 million. The decrease in property development and capital improvements for 2017, as compared to the same period in 2016, was primarily due to the timing and completion of six consolidated operating properties in 2016 and 2017, partially offset by an increase in redevelopment expenditures relating to our reposition program at several of our operating properties. The property development and capital improvements during 2017 and 2016, included the following:

	December 31,
(in millions)	2017		2016
Expenditures for new development, including land	$	163.1	$	220.4
Capitalized interest, real estate taxes, and other capitalized indirect costs	25.3		29.8
Reposition expenditures	40.4		23.1
Capital expenditures	70.3		69.7
Total	$	299.1	$	343.0

During the year ended December 31, 2016, cash outflows in investing activities also included the purchase of a short-term investment for $100.0 million and increases of $7.5 million in a note receivable balance outstanding on a real estate secured loans to an unaffiliated third party.

37

Net cash used in financing activities totaled approximately $112.9 million during the year ended December 31, 2017 as compared to approximately $904.2 million during the year ended December 31, 2016. During 2017, we repaid our 5.83% senior unsecured note payable of approximately $246.8 million, as well as our tax-exempt secured note payable of approximately $30.7 million. We also used approximately $280.8 million to pay distributions to common shareholders and non-controlling interest holders. These cash outflows were partially offset by net proceeds of approximately $445.0 million from the issuances of approximately 4.8 million common shares through an equity offering completed in September 2017 and issuances under our 2017 ATM program. During 2016, we had payments, net of proceeds, of $244.0 million on our unsecured credit facility and other short-term borrowings. We also used approximately $663.4 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.

The following is a discussion of our cash flows for the years ended December 31, 2016 and 2015.

Net cash from operating activities was approximately $443.1 million during the year ended December 31, 2016 as compared to approximately $423.2 million during the year ended December 31, 2015. The increase was primarily due to higher net property-level NOI, primarily due to the growth in revenues attributable to increased rental rates from our same store communities and growth in the number of non-same store properties resulting from the stabilization of nine operating properties in 2015 and 2016, the completion and partial lease-up of two operating properties in 2016, and the partial lease-up of two properties under construction at December 31, 2016. The increase was also 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 in 2016, as well as the disposition of three other operating properties in 2015 and the disposition of one dual-phased operating property and six other operating properties in 2016. See further discussions of our 2016 operations as compared to 2015 in "Results of Operations."

Net cash from investing activities during the year ended December 31, 2016 totaled approximately $690.4 million as compared to net cash used in investing activities of approximately $293.2 million during the year ended December 31, 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 approximately $515.8 million, net of expenses, from the sale of one dual-phased operating property and six other properties and one land holding. These cash inflows were partially offset by cash outflows for property development and capital improvements of approximately $343.0 million during 2016 as compared to approximately $411.8 million in 2015, primarily due to the completion of nine operating properties in 2015 and 2016, and the completion of repositions at several of our operating properties. The expenditures related to property development and capital improvements during the years ended December 31, 2016 and 2015 included the following:

	December 31,
(in millions)	2016		2015
Expenditures for new development, including land	$	220.4	$	285.8
Capitalized interest, real estate taxes, and other capitalized indirect costs	29.8		30.9
Reposition expenditures	23.1		31.2
Capital expenditures	69.7		63.9
Total	$	343.0	$	411.8

During the year ended December 31, 2016, cash outflows from investing activities also included the purchase of a short-term investment for $100.0 million. During the year ended December 31, 2015, cash outflows also included $13.8 million relating to capital improvements and reposition expenditures from our discontinued operations. These cash outflows were offset by proceeds of approximately $145.0 million from the sale of three operating properties and two land holdings.

Net cash used in financing activities totaled approximately $904.2 million during the year ended December 31, 2016 as compared to approximately $273.2 million during the year ended December 31, 2015. During 2016, we had net payments of $244.0 million on our unsecured credit facility and other short-term borrowings. We also used approximately $663.4 million to pay distributions to common shareholders and non-controlling interest holders which included the $4.25 per common share special dividend payment made on September 30, 2016. During 2015, we used $250.0 million to repay maturing unsecured notes payable and approximately $3.0 million to pay principal amortization payments. We also used approximately $253.1 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 2015 were partially offset by net proceeds from our unsecured line of credit and other short-term borrowings of $244.0 million. 

38

Financial Flexibility

We have a $600.0 million unsecured 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 $900.0 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 this credit facility is based upon LIBOR plus a margin which is subject to change as our credit ratings change. Advances under this 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 $300.0 million or the remaining amount available under the 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 $50.0 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 December 31, 2017, we had no balances outstanding on our $600.0 million credit facility and we had outstanding letters of credit totaling approximately $13.4 million, leaving approximately $586.6 million available under our credit facility.

We also have a $45.0 million unsecured short-term borrowing facility which matures in May 2018. The interest rate is based on LIBOR plus 0.95%. At December 31, 2017, we had no balances outstanding on this unsecured short-term borrowing facility, leaving $45.0 million available under this 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 million preferred shares. At December 31, 2017 we had approximately 92.7 million common shares outstanding, net of treasury shares and shares held in our deferred compensation arrangements, and no preferred shares outstanding.

In May 2017, we created an at-the market ("ATM") share offering program through which we can, but have no obligation to, sell common shares having an aggregate offering price of up to $315.3 million (the "2017 ATM program"), in amounts and at times as we determine, into the existing trading market at current market prices as well as through negotiated transactions. Actual sales from time to time may depend on a variety of factors including, among others, market conditions, the trading price of our common shares, and determinations by management of the appropriate sources of funding for us. The proceeds from the sale of our common shares under the 2017 ATM program are intended to be used for general corporate purposes, which may include reducing future borrowings under our $600.0 million unsecured line of credit, the repayment of other indebtedness, the redemption or other repurchase of outstanding debt or equity securities, funding for development activities, and financing for acquisitions. As of the date of this filing, we had common shares having an aggregate offering price of up to $312.8 million remaining available for sale under the 2017 ATM program. No additional shares under the 2017 ATM program were sold subsequent to December 31, 2017 through the date of this filing.

We believe our ability to access capital markets is enhanced by our senior unsecured debt ratings by Moody’s, Fitch, and Standard and Poor's, which are currently A3 with stable outlook, A- with stable 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. We believe scheduled payments of debt in 2018 are manageable at approximately $173.7 million which represents approximately 7.9% of our total outstanding debt, and includes amortization of debt discounts and debt issuance costs, net of scheduled principal payments of approximately $1.3 million. See Note 9, “Notes Payable,” in the notes to Consolidated Financial Statements for further discussion of scheduled maturities.

We estimate the additional cost to complete the construction of the seven consolidated projects to be approximately $282.3 million. Of this amount, we expect to incur costs between approximately $140 million and $160 million during 2018 and to incur the remaining costs during 2019 and 2020. Additionally, we expect to incur costs between approximately $45 million and $55 million related to the start of new development activities, between approximately $37 million and $41 million of repositions and revenue enhancing expenditures, between approximately $28 million and $32 million in redevelopment expenditures and between approximately $65 million and $69 million of additional recurring capital expenditures during 2018.

We anticipate meeting our near-term liquidity requirements through a combination of one or more of the following: cash and cash equivalents, cash flows generated from operations, draws on our unsecured credit facility or other short-term

39

borrowing, the use of debt and equity offerings under our automatic shelf registration statement, proceeds from property dispositions, equity issued from 2017 our ATM program, other unsecured borrowings, or secured mortgages. We continue to evaluate our operating properties 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 December2017, we announced our Board of Trust Managers had declared a quarterly dividend of $0.75 per common share to our common shareholders of record as of December 15, 2017. This dividend was subsequently paid on January 17, 2018 and we paid equivalent amounts per unit to holders of common operating partnership units. When aggregated with previous 2017 dividends, this distribution to common shareholders and holders of the common operating partnership units equates to an annual dividend rate of $3.00 per share or unit for the year ended December 31, 2017.

In the first quarter of 2018, the Company's Board of Trust Managers declared a first quarter dividend of $0.77 per common share to our common shareholders of record as of March 30, 2018. Future dividend payments are paid at the discretion of the Board of Trust Managers and depend on cash flows generated from operations, the Company's financial condition and capital requirements, distribution requirements under the REIT provisions of the Code and other factors which may be deemed relevant by our Board of Trust Managers. Assuming similar dividend distributions for the remainder of 2018, our annualized dividend rate for 2018 would be $3.08.

The following table summarizes our known contractual cash obligations as of December 31, 2017:

(in millions)	Total		2018		2019		2020			2021		2022		Thereafter
Debt maturities (1)	$	2,204.6	$	173.7	$	643.0	$	(1.2	)	$	249.1	$	349.3	$	790.7
Interest payments (2)	356.6		90.1		63.3		55.5			49.1		43.3		55.3
Non-cancelable lease payments	20.6		2.9		2.8		2.8			2.8		2.6		6.7
	$	2,581.8	$	266.7	$	709.1	$	57.1		$	301.0	$	395.2	$	852.7

(1) Includes amortization of debt discounts and debt issuance costs, net of scheduled principal payments.

(2) Includes contractual interest payments for our senior unsecured notes and secured notes. The interest payments on certain secured notes with floating interest rates were calculated based on the interest rates in effect as of December 31, 2017.

Off-Balance Sheet Arrangements

The joint ventures in which we have an interest have been funded in part with secured, third-party debt. At December 31, 2017, our unconsolidated joint ventures had outstanding debt of approximately $514.5 million, of which our proportionate share was approximately $161.0 million. As of December 31, 2017, we had no outstanding guarantees related to the loans of our unconsolidated joint ventures.

Inflation

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

Critical Accounting Policies

The preparation of our financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the balance sheet date, and the amounts of revenues and expenses recognized during the reporting period. These estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances. The following is a discussion of our critical accounting policies. For a discussion of all of our significant accounting policies, see Note 2, "Summary of Significant Accounting Policies and Recent Accounting Pronouncements," to the accompanying consolidated financial statements.

Principles of Consolidation. We may enter into various joint venture agreements with unrelated third parties to hold or develop real estate assets. We must determine for each of these joint ventures whether to consolidate the entity or account for our investment under the equity or cost basis of accounting. Investments acquired or created are 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

40

consolidation primarily using a voting interest model. In determining if we have a controlling financial interest, we consider factors such as ownership interests, authority to make decisions, kick-out rights and participating rights. We evaluate our accounting for investments on a quarterly basis or when a reconsideration event (as defined by GAAP) with respect to our investments occurs. The analysis required to identify VIEs and primary beneficiaries is complex and requires substantial management judgment.

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 undiscounted cash flows, trends, strategic decisions regarding future development plans, and other factors in our assessment of whether impairment conditions exist. While we believe our estimates of future cash flows are reasonable, different assumptions regarding a number of factors, including market rents, economic conditions, and occupancies, could significantly affect these estimates. In estimating fair value, management uses appraisals, management estimates, and discounted cash flow calculations which 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.

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

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

Cost Capitalization. Real estate assets are carried at cost plus capitalized carrying charges. Carrying charges are primarily interest and real estate taxes which are capitalized as part of properties under development. Capitalized interest is generally based on the weighted average interest rate of our unsecured debt. Expenditures directly related to the development and improvement of real estate assets are capitalized at cost as land and buildings and improvements. Indirect development costs, including salaries and benefits and other related costs directly attributable to the development of properties, are also capitalized. We begin capitalizing development, construction, and carrying costs when the development of the future real estate asset is probable and activities necessary to 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. Included in capitalized costs are indirect costs associated with our development and redevelopment activities. The estimates used by management require judgment, and accordingly we believe cost capitalization to be a critical accounting estimate.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to certain market risks inherent in our operations. These risks generally arise from transactions entered into in the normal course of business. We believe our primary market risk exposure relates to interest rate risk. We do not enter into derivatives or other financial instruments for trading or speculative purposes.

The table below provides information about our liabilities sensitive to changes in interest rates as of December 31, 2017 and 2016.

	December 31, 2017							December 31, 2016
	Amount (in  millions)		Weighted Average Maturity (in years)	Weighted Average Interest Rate		% Of Total		Amount (in  millions)		Weighted Average Maturity (in years)	Weighted Average Interest Rate		% Of Total
Fixed rate debt	$	2,029.6	4.6	4.5	%	92.1	%	$	2,274.9	5.0	4.7	%	91.7	%
Variable rate debt	175.0		0.8	1.9		7.9		205.7		3.2	1.4	%	8.3	%

We have historically used variable rate indebtedness available under our unsecured credit facility and other short-term borrowings to initially fund acquisitions and our development pipeline. To the extent we utilize our unsecured credit facility and increase our variable rate indebtedness, our exposure to increases in interest rates will also increase.

For fixed rate debt, interest rate changes affect the fair market value but do not impact net income attributable to common shareholders or cash flows. Conversely, for floating rate debt, interest rate changes generally do not affect the fair market value but do impact net income attributable to common shareholders and cash flows, assuming other factors are held constant. Holding other variables constant, a one percentage point variance in interest rates would change the unrealized fair market value of the fixed rate debt by approximately $82.2 million. The net income attributable to common shareholders and cash flows impact on the next year resulting from a one percentage point variance in interest rates on floating rate debt would be approximately $1.8 million, holding all other variables constant.

We currently use interest rate swaps to reduce the impact of interest rate fluctuations on certain indebtedness, not for trading or speculative purposes. During the year ended December 31, 2017, we had three forward interest rate swap agreements with a total notional amount of $200.0 million that become effective October 31, 2018 to hedge a portion of anticipated future fixed rate debt issuances. We expect to cash settle these contracts relating to these outstanding swaps upon the issuance of debt in 2018 and either pay or receive cash for the fair value of the swap at time of settlement. The impact of settling our position, assuming debt is issued as expected, will be recognized over the life of the issued debt as an adjustment to interest expense.

Derivative financial investments expose us to credit risk in the event of non-performance by the counterparties under the terms of the interest rate hedge agreements. The Company has agreements with derivative counterparties containing provisions where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company's default on the indebtedness. As of December 31, 2017, the fair value of derivatives in a net liability position, which excludes any adjustment for nonperformance risk, related to these agreements was approximately $0.5 million.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934 as follows:

A process designed by, or under the supervision of, the Company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the Company's board of trust managers, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

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

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

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

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2017. In making this assessment, management used the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on our assessment, management concluded our internal control over financial reporting is effective as of December 31, 2017.

Deloitte & Touche LLP, an independent registered public accounting firm, has issued an attestation report regarding the effectiveness of our internal control over financial reporting, which is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trust Managers and Shareholders of Camden Property Trust

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Camden Property Trust and subsidiaries (the “Company”) as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the financial statements as of and for the year ended December 31, 2017, of the Company and our report dated February 16, 2018, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

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 December 31, 2017, approximately 2.9 million fungible units were available under the 2011 Share Plan, which results in approximately 0.8 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trust Managers and Shareholders of Camden Property Trust

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Camden Property Trust and subsidiaries (the “Company”) as of December 31, 2017 and 2016, the related consolidated statements of income and comprehensive income, equity, and cash flows, for each of the three years in the period ended December 31, 2017, and the related notes and the schedules listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 16, 2018, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company's auditor since 1993.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business

Business. Formed on May 25, 1993, Camden Property Trust, a Texas real estate investment trust (“REIT”), is primarily engaged in the ownership, management, development, redevelopment, acquisition, and construction of multifamily apartment communities. Our multifamily apartment communities are referred to as “communities,” “multifamily communities,” “properties,” or “multifamily properties” in the following discussion. As of December 31, 2017, we owned interests in, operated, or were developing 162 multifamily properties comprised of 55,143 apartment homes across the United States. Of the 162 properties, seven properties were under construction, and will consist of a total of 2,110 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 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. In determining if we have a controlling financial interest, we consider factors such as ownership interests, authority to make decisions, kick-out rights and participating rights. At December 31, 2017, 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 continue to consolidate these operating partnerships.

Acquisitions of Real Estate. Upon acquisition of real estate, we determine the fair value of tangible and intangible assets, which includes land, buildings (as-if-vacant), furniture and fixtures, the value of in-place leases, including above and below market leases, and acquired liabilities. In estimating these values, we apply methods similar to those used by independent appraisers of income-producing property. Upon our adoption of Accounting Standard Update 2017-01 ("ASU 2017-01") on January 1, 2017, as discussed below in Recent Accounting Pronouncements, we believe most future transaction costs relating to acquisition of operating assets will be capitalized. Prior to our adoption of ASU 2017-01 transaction costs associated with the acquisition of operating assets were expensed as incurred. Estimates of fair value of acquired debt are based upon interest rates available for the issuance of debt with similar terms and remaining maturities. Depreciation is computed on a straight-line basis over the remaining useful lives of the related tangible assets. The value of in-place leases and above or below market leases is amortized over the estimated average remaining life of leases in place at the time of acquisition. The net carrying value of below market leases is included in other liabilities in our consolidated balance sheets and the net carrying value of in-place leases is included in other assets, net in our consolidated balance sheets.

During the year ended December 31, 2017, we recognized amortization expense related to in-place leases of approximately $1.3 million. During the year ended December 31,2015, we recognized revenues related to below market leases of approximately $0.1 million and amortization expense related to in-place leases of approximately $0.5 million. We did not recognize any revenue or amortization expense related to below market or in-place leases for the year ended December 31, 2016.

The weighted average amortization period of in-place leases was approximately six months for the year ended December 31, 2017. The weighted average amortization period of below market leases and in-place leases were approximately eight months for the year ended December 31, 2015.

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 undiscounted cash flows, trends, strategic decisions regarding future development plans, and other factors in our assessment of whether impairment conditions exist. While we believe our estimates of future cash flows are reasonable, different assumptions regarding a number of factors, including market rents, economic conditions, and occupancies, could significantly affect these estimates. In estimating fair value, management uses appraisals, management estimates, and discounted cash flow calculations which 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 years ended December 31, 2017, 2016, or 2015.

The value of our properties under development depends on market conditions, including estimates of the project start date as well as estimates of demand for multifamily communities. We have reviewed market trends and other marketplace

F-9

information and have incorporated this information as well as our current outlook into the assumptions we use in our impairment analyses. Due to the judgment and assumptions applied in the impairment analyses, it is possible actual results could differ substantially from those estimated.

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

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

Short-term Investments. Our short-term investments consisted of certificates of deposit which have original maturities of more than three months but less than one year.

Cost Capitalization. Real estate assets are carried at cost plus capitalized carrying charges. Carrying charges are primarily interest and real estate taxes which are capitalized as part of properties under development. Capitalized interest is generally based on the weighted average interest rate of our unsecured debt. Expenditures directly related to the development and improvement of real estate assets are capitalized at cost as land and buildings and improvements. Indirect development costs, including salaries and benefits and other related costs directly attributable to the development of properties, are also capitalized. We begin capitalizing development, construction, and carrying costs when the development of the future real estate asset is probable and activities necessary to 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. As apartment homes within development properties are completed, the total capitalized development cost of each apartment home is transferred from properties under development including land to buildings and improvements.

As discussed above, carrying charges are principally interest and real estate taxes capitalized as part of properties under development. Capitalized interest was approximately $15.2 million, $18.2 million, and $19.3 million for the years ended December 31, 2017, 2016, and 2015, respectively. Capitalized real estate taxes were approximately $2.4 million, $4.5 million, and $3.6 million for the years ended December 31, 2017, 2016, and 2015, respectively.

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

We also incur expenditures related to renovation and construction of office space we lease and we capitalize these leasehold improvements as furniture, fixtures, equipment and other. We depreciate these costs using the straight-line method over the shorter of the lease term or the useful life of the improvement.

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

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

Derivative Financial Instruments. Derivative financial instruments are recorded in the consolidated balance sheets at fair value and we do not apply master netting for financial reporting purposes. Accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows

F-10

or other types of forecasted transactions are cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes attributable to the earnings effect of the hedged transactions. We may enter into derivative contracts which are intended to economically hedge certain of our risks, for which hedge accounting does not apply or we elect not to apply hedge accounting.

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 during the period 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 consolidated balance sheets. Subsequent to classification of a property as held for sale, no further depreciation is recorded. Consolidated operating properties sold or classified as held for sale, which do not meet the above criteria of discontinued operations are not included in discontinued operations and the related gains and losses are included in continuing operations. 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 accounting principles generally accepted in the United States of America ("GAAP"), provided various criteria relating to the terms of sale and any subsequent involvement with the real estate sold are satisfied.

See Note 7, "Acquisitions, Dispositions, and Discontinued Operations," for discussion of discontinued operations for the year ended December 31, 2016. There were no discontinued operations for the years ended 2017 or 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 receive to sell an asset, or pay to transfer a liability, in an orderly transaction with a market participant at the measurement date. In the absence of such data, fair value is estimated using internal information consistent with what market participants would use in a hypothetical transaction.

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

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

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

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

Recurring Fair Value Measurements. The following describes the valuation methodologies we use to measure different financial instruments at fair value on a recurring basis:

Deferred Compensation Plan Investments. The estimated fair values of investment securities classified as deferred compensation plan investments are based on quoted market prices utilizing public information for the same transactions. Our deferred compensation plan investments are recorded in other assets in our 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.

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

F-11

rates rise above the strike rate of the caps. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observed market interest rate curves and volatilities.

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

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 December 31, 2017 and 2016, 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 value of our notes receivable, which are included in other assets, net in our consolidated balance sheets, approximates their fair value. The estimated fair values 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.

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

Reclassifications. Certain reclassifications have been made to amounts in prior period financial statements to conform to the current period presentation. We reclassified certain insignificant amounts in the consolidated statements of cash flows for the years ended December 31, 2016 and 2015. These reclassifications had no impact on our consolidated cash flows from operating, investing or financing activities.

Insurance. Our primary lines of insurance coverage are property, general liability, health, and workers’ compensation. We believe our insurance coverage adequately insures our properties against the risk of loss attributable to fire, earthquake, hurricane, tornado, flood, and other perils and adequately insures us against other risks. Losses are accrued based upon our estimates of the aggregate liability for claims incurred using certain actuarial assumptions followed in the insurance industry and based on our experience.

Other Assets, Net. Other assets in our consolidated financial statements include investments under deferred compensation plans, deferred financing costs, non-real estate leasehold improvements and equipment, notes receivable, prepaid expenses, the value of in-place leases net of related accumulated amortization, and other miscellaneous receivables. Investments under deferred compensation plans are classified as trading securities and are adjusted to fair market value at period end. For a further discussion of our investments under deferred compensation plans, see Note 11, “Share-based Compensation and Benefit Plans.” Deferred financing costs are related to our unsecured credit facility and unsecured short-term borrowing facility, and are amortized no longer than the terms of the related facilities on the straight-line method, which approximates the effective interest method. Corporate leasehold improvements and equipment are depreciated using the straight-line method over the shorter of the expected useful lives or the lease terms which generally range from three to ten years.

Our notes receivable relate to real estate secured loans to unaffiliated third parties. At December 31, 2017 and 2016, we had one outstanding note receivable balance of approximately $18.8 million and $17.2 million, respectively. The weighted average interest rates were approximately 4.0% for each of the years ended December 31, 2017 and 2016 related to such note.

F-12

At December 31, 2017, construction was complete on this project and we were not committed to fund any additional amounts under the note. Interest is recognized over the life of the note 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. All cash receipts on impaired notes are applied to reduce the principal amount of such notes until the principal has been recovered and, thereafter, are recognized as interest income. There were no impairments as of December 31, 2017 or 2016.

Reportable Segments. We operate in a single reportable segment which includes the ownership, management, development, redevelopment, acquisition, and construction of multifamily apartment communities. Each of our operating properties is considered a separate operating segment as each property earns revenues and incurs expenses, individual operating results are reviewed and discrete financial information is available. We do not distinguish or group our consolidated operations based on geography, size or type. Our multifamily apartment communities have similar long-term economic characteristics and provide similar products and services to our residents. Further, all material operations are within the United States and no multifamily apartment community comprises more than 10% of consolidated revenues. As a result, our operating properties are aggregated into a single reportable segment. Our multifamily communities generate rental revenue and other income through the leasing of apartment homes, which comprised approximately 99% of our total property revenues and total non-property income, excluding income on deferred compensation plans, for each of the years ended December 31, 2017, 2016, and 2015.

Restricted Cash. Restricted cash consists of escrow deposits held by lenders for property taxes, insurance and replacement reserves, cash required to be segregated for the repayment of residents’ security deposits, and escrowed amounts related to our development and acquisition activities. Substantially all restricted cash is invested in demand and short-term instruments.

Share-based Compensation. Compensation expense associated with share-based awards is recognized in our consolidated statements of income and comprehensive income using the grant-date fair values. Compensation cost for all share-based awards, including options, requires measurement at estimated fair value on the grant date and recognition of compensation expense over the requisite service period for awards expected to vest. The fair value of stock option grants is estimated using the Black-Scholes valuation model. Valuation models require the input of assumptions, including judgments to estimate the expected stock price volatility, expected life, and forfeiture rate. The compensation cost for share-based awards is based on the market value of the shares on the date of grant.

Use of Estimates. In the application of GAAP, management is required to make estimates and assumptions which affect the reported amounts of assets and liabilities at the date of the financial statements, results of operations during the reporting periods, and related disclosures. Our more significant estimates include estimates supporting our impairment analysis related to the carrying values of our real estate assets. These estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances. Future events rarely develop exactly as forecasted, and the best estimates routinely require adjustment.

Recent Accounting Pronouncements. In January 2017, the Financial Accounting Standards Board ("FASB") issued ASU 2017-01, "Clarifying the Definition of a Business (Topic 805)." ASU 2017-01 clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. ASU 2017-01 is effective for interim and annual periods beginning after December 15, 2017, early adoption was permitted, and we adopted ASU 2017-01 as of January 1, 2017. We believe most of our future acquisitions of operating properties will qualify as asset acquisitions and most future transaction costs associated with these acquisitions will be capitalized.

In February 2017, the FASB issued ASU 2017-05, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets." ASU 2017-05 clarifies the definition of an in-substance nonfinancial asset and changes the accounting for partial sales of nonfinancial assets to be more consistent with the accounting for a sale of a business pursuant to ASU 2017-01. This update is effective for interim and annual periods beginning after December 15, 2017 using a full retrospective or modified retrospective method and is required to be adopted in conjunction with ASU 2014-09, "Revenue from Contracts with Customers" discussed below. We adopted ASU 2017-05 as of January 1, 2018, along with our adoption of ASU 2014-09, using the modified retrospective method and it did not have a material impact on our consolidated financial statements. We believe most of our future contributions of nonfinancial assets to our joint ventures, if any, will result in the recognition of a full gain or loss as if we sold 100% of the nonfinancial asset and we will also measure our retained interest at fair value.

In May 2014, the FASB issued ASU 2014-09 which prescribes a single, common revenue standard to replace most existing revenue recognition guidance in GAAP, including most industry-specific requirements. The standard outlines a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied. Several ASUs have been issued since the issuance of ASU 2014-09 which modify certain sections of the new revenue recognition standard, and are

F-13

intended to promote a more consistent interpretation and application of the principles outlined in the standard. We adopted ASU 2014-09, and all related amendments, effective January 1, 2018 using the modified retrospective with cumulative-effect transition method which requires us to recognize the cumulative effect of initially applying the new revenue standard as an adjustment, if any, to the opening balance of retained earnings. We have identified our revenue streams and finalized our evaluation of the impact on our consolidated financial statements and internal accounting processes. Upon adoption, we will present certain revenue streams, which are currently included as a component of our other property revenues, as rental revenues due to the nature and timing of revenue recognition for these revenue streams. The new presentation will be applied prospectively upon adoption as this adjustment will not have an impact upon total property revenues or the opening balance of retained earnings and the adoption of ASU 2014-09 and its related amendments will not have a material impact on our consolidated financial statements as the majority of our revenue is derived from real estate lease contracts. Had ASU 2014-09 been effective as of January 1, 2017, we would have reclassified approximately $21.9 million from other property revenue to rental revenue for the year end December 31, 2017.

In February 2016, the FASB issued ASU 2016-02, "Leases." ASU 2016-02 supersedes the current accounting for leases and while retaining two distinct types of leases, finance and operating, (i) requires lessees to record a right of use asset and a related liability for the rights and obligations associated with a lease, regardless of lease classification, and recognize lease expense in a manner similar to current accounting (ii) eliminates most real estate specific lease provisions, and (iii) aligns many of the underlying lessor model principles with those in the new revenue standard. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. We are required to adopt ASU 2016-02 using the modified retrospective approach which requires us to record leases existing as of or are entered into after the beginning of the earliest comparative period presented in the financial statements under the new lease standard. We anticipate adopting ASU 2016-02 as of January 1, 2019. Based on our assessments, most of our operating lease commitments will be subject to the new guidance and recognized as operating lease liabilities and right-of-use assets upon adoption and believe our adoption of the new leasing standard will have an immaterial increase in the assets and liabilities on our consolidated balance sheets, with no material impact to our consolidated statements of income and comprehensive income. However, the ultimate impact will depend on our lease portfolio as of the adoption date.

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 we adopted ASU 2016-09 as of January 1, 2017. Upon adoption we elected to recognize forfeitures of share-based payment awards as they occur, rather than estimating forfeitures at the time awards are granted. Historically, our estimated forfeitures approximated actual forfeitures and the impact of the change in policy upon our adoption of ASU 2016-09 did not have a material impact on our consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, "Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)." ASU 2016-15 clarifies how eight 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 retrospectively. We adopted ASU 2016-15 as of January 1, 2018 using the retrospective method by applying the cumulative earnings approach to classify distributions received from our equity method investees and it did not have a material effect on our consolidated statements of cash flows upon adoption.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." ASU 2017-12 amends the hedge accounting model to provide better insight to risk management activities in the financial statements, reduces the complexity in cash flow hedges of interest rate risk, eliminates the requirement to separately measure and report hedge ineffectiveness, requires the entire change in the fair value of a hedging instrument included in the assessment of the hedge effectiveness to be recorded in other comprehensive income, with amounts reclassified to earnings to be presented in the same line item used to present the earnings effect of the hedged item when the hedged item affects earnings and allows the initial prospective quantitative assessment of hedge effectiveness to be performed at any time after hedge designation, but no later than the first quarterly effectiveness testing date. ASU 2017-12 is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The amendments in this standard must be applied using the modified retrospective approach for cash flow and net investment hedge relationships existing on the date of adoption. We adopted ASU 2017-12 in the third quarter of 2017, and this adoption had no impact upon adoption as we had no hedging activities in the prior periods presented.

3. Per Share Data

Basic earnings per share are computed using net income attributable to common shareholders and the weighted average number of common shares outstanding. Diluted earnings per share reflect common shares issuable from the assumed conversion of common share options and share awards granted and units convertible into common shares. Only those items having a dilutive impact on our basic earnings per share are included in diluted earnings per share. Our unvested share-based awards are considered participating securities and are reflected in the calculation of basic and diluted earnings per share using the two-class method. The number of common share equivalent securities excluded from the diluted earnings per share calculation was approximately 1.5 million, 2.4 million, and 2.6 million for the years ended December 31, 2017, 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 calculation as they are anti-dilutive.

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

In May 2017, we created an at-the market ("ATM") share offering program through which we can, but have no obligation to, sell common shares having an aggregate offering price of up to $315.3 million (the "2017 ATM program"), in amounts and at times as we determine, into the existing trading market at current market prices as well as through negotiated transactions. Actual sales from time to time may depend on a variety of factors including, among others, market conditions, the trading price of our common shares, and determinations by management of the appropriate sources of funding for us. The proceeds from the sale of our common shares under the 2017 ATM program are intended to be used for general corporate purposes, which may include reducing future borrowings under our $600 million unsecured line of credit, the repayment of other indebtedness, the redemption or other repurchase of outstanding debt or equity securities, funding for development activities, and financing for acquisitions.

The following table presents activity under the 2017 ATM program for the year ended December 31, 2017:

(in thousands, except per share amounts)	Year Ended December 31, 2017
Total net consideration	$	2,513.6
Common shares sold	28.1
Average price per share	$	90.44

As of the date of this filing, we had common shares having an aggregate offering price of up to $312.8 million remaining available for sale under the 2017 ATM program. No additional shares were sold under the 2017 ATM program subsequent to December 31, 2017 through the date of this filing.

In November 2014, we created an ATM share offering program through which we could, but had no obligation to, sell common shares having an aggregate offering price of up to $331.3 million (the "2014 ATM program"). Concurrently with the creation of the 2017 ATM program in May 2017 discussed above, we terminated the 2014 ATM program and rolled the $315.3 million remaining available for sale under the 2014 ATM program into the 2017 ATM program. Upon termination, no further common shares were available for sale under the 2014 ATM program.

We have a repurchase plan approved by our Board of Trust Managers which allows for the repurchase of up to $500 million of our common equity securities through open market purchases, block purchases, and privately negotiated transactions. 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. There were no repurchases for the years ended December 31, 2017, 2016, or 2015 under this program.

We currently have an automatic shelf registration statement which allows us to offer, from time to time, common shares, preferred shares, debt securities, or warrants. Our Amended and Restated Declaration of Trust provides we may issue up to 185 million shares of beneficial interest, consisting of 175 million common shares and 10 million preferred shares. At December 31, 2017, we had approximately 92.7 million common shares outstanding, net of treasury shares and shares held in our deferred compensation arrangements, and no preferred shares outstanding. In September 2017, we issued approximately 4.8 million common shares in a public equity offering and received approximately $442.5 million in net proceeds. We intend to use the net proceeds for general corporate purposes, which may include financing for acquisitions and funding for development activities, reducing borrowings under our $600 million unsecured line of credit, the repayment of indebtedness, and the redemption or other repurchase of outstanding debt or equity securities.

In addition to our 2016 quarterly dividends, 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 of gains on dispositions of assets completed in 2016, which was paid on September 30, 2016. We also paid equivalent amounts per unit to holders of the common operating partnership units.

5. Operating Partnerships

At December 31, 2017, approximately 4% of our consolidated multifamily apartment homes were held in Camden Operating, L.P. (“Camden Operating” or the “operating partnership”). Camden Operating has 11.9 million outstanding common limited partnership units and as of December 31, 2017, we held 92% of the outstanding common limited partnership units and the sole 1% general partnership interest of the operating partnership. The remaining common limited partnership units, comprising approximately 0.8 million units, are primarily held by former officers, directors, and investors of Paragon Group, Inc., which we acquired in 1997. Each common limited partnership unit is redeemable for one common share of Camden Property Trust or cash at our election. Holders of common limited partnership units are not entitled to rights as shareholders prior to redemption of their common limited partnership units. No member of our management owns Camden Operating common limited partnership units.

F-16

At December 31, 2017, approximately 34% of our consolidated multifamily apartment homes were held in Camden Summit Partnership, L.P. (the “Camden Summit Partnership”). Camden Summit Partnership has 22.8 million outstanding common limited partnership units and as of December 31, 2017, we held 94% of the outstanding common limited partnership units and the sole 1% general partnership interest of Camden Summit Partnership. The remaining common limited partnership units, comprising approximately 1.1 million units, are primarily held by former officers, directors, and investors of Summit Properties Inc., which we acquired in 2005. Each common limited partnership unit is redeemable for one common share of Camden Property Trust or cash at our election and holders of common limited partnership units are not entitled to rights as shareholders prior to redemption of their common limited partnership units. No member of our management owns Camden Summit Partnership common limited partnership units, and two of our ten trust managers own Camden Summit Partnership common limited partnership units.

6. Income Taxes

We have maintained and intend to maintain our election as a REIT under the Internal Revenue Code of 1986, as amended. In order for us to continue to qualify as a REIT we must meet a number of organizational and operational requirements, including a requirement to distribute annual dividends to our shareholders equal to a minimum of 90% of our 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 for taxable years ended before January 1, 2018 any applicable alternative minimum tax. In addition, we may not be able to requalify as a REIT for the four subsequent taxable years. Historically, we have incurred only state and local income, franchise, and excise taxes. Taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to applicable federal, state, and local income taxes. Our operating partnerships are flow-through entities and are not subject to federal income taxes at the entity level.

We have recorded income, franchise, and excise taxes in the consolidated statements of income and comprehensive income for the years ended December 31, 2017, 2016 and 2015 as income tax expense. Income taxes for the years ended December 31, 2017, 2016 and 2015, 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.

For income tax purposes, distributions to common shareholders are characterized as ordinary income, capital gains or as a return of a shareholder's invested capital. A summary of the income tax characterization of our distributions paid per common share for the years ended December 31, 2017, 2016 and 2015 is set forth in the following table:

	Year Ended December 31,
	2017		2016		2015
Common Share Distributions
Ordinary income	$	2.38	$	—	$	1.88
Long-term capital gain	0.41		5.02		0.70
Unrecaptured Sec. 1250 gain	0.21		2.23		0.22
Total	$	3.00	$	7.25	$	2.80

We have taxable REIT subsidiaries which are subject to federal and state income taxes. At December 31, 2017, our taxable REIT subsidiaries had immaterial net operating loss carryforwards (“NOL’s”) which expire in years 2034 to 2037. Because NOL’s are subject to certain change of ownership, continuity of business, and separate return year limitations, and because we believe it is unlikely the available NOL’s will be utilized or if utilized, any amounts will be immaterial, no benefits related to these NOL’s have been recognized in our consolidated financial statements.

The carrying value of net assets reported in our consolidated financial statements at December 31, 2017 exceeded the tax basis by approximately $1.3 billion.

Income Tax Expense. For the tax year ended December 31, 2017, we had income tax expense of approximately $1.2 million, and $1.6 million and $1.9 million for the tax years ended December 31, 2016 and 2015, respectively. The income tax expense for the year ended December 31, 2017 also included a tax benefit which related to a state income tax refund received of approximately $0.5 million. Income tax for the years ended December 31, 2017, 2016, and 2015 was comprised mainly of state income tax and federal income tax related to one of our taxable REIT subsidiaries.

F-17

Income Tax Expense – Deferred. For the years ended December 31, 2017, 2016, and 2015, our deferred tax expense was not significant.

Camden Property Trust's and our subsidiaries’ income tax returns are subject to examination by federal, state and local tax jurisdictions for years 2014 through 2016. NOL's and other tax attributes generated in years prior to 2014 are also subject to challenge in any examination of those tax years. We believe we have no uncertain tax positions or unrecognized tax benefits requiring disclosure as of and for the periods presented.

Tax reform. The 2017 Tax Act was passed on December 22, 2017 which includes a number of changes to the corporate income tax system, including but not limited to a reduction in the statutory federal corporate income tax rate from 35% to 21% for non-REIT “C” corporations, changes to deductions for certain pass-through business income, and possible limitations on interest expense, depreciation and the deductibility of executive compensation. As a REIT, we generally will not be subject to federal income tax on our taxable income at the corporate level and do not believe any of the changes from the 2017 Tax Act will have a material impact on our consolidated financial statements.

7. Acquisitions, Dispositions, and Discontinued Operations

Asset Acquisition of Operating Property. In June 2017, we purchased one operating property, Camden Buckhead Square, comprised of 250 apartment homes, located in Atlanta, Georgia, for approximately $58.3 million. In January 2018, we acquired one operating property comprised of 358 apartment homes located in St. Petersburg, Florida, for approximately $126.9 million. In February 2018, we acquired one operating property comprised of 333 apartment homes located in Orlando, Florida, for approximately $81.4 million.

Acquisitions of Land. In April 2017, we acquired approximately 8.2 acres of land in San Diego, California for approximately $20.0 million. During the year ended December 31, 2016, we acquired an aggregate of approximately 4.6 acres of land located in Denver, Colorado and Charlotte, North Carolina for approximately $19.9 million.

Acquisition of Non-controlling Ownership Interest. We did not acquire any additional non-controlling ownership interest in 2017 or 2016. In March 2015, we purchased the remaining 0.01% non-controlling interest in two fully consolidated joint ventures, which own an aggregate of 798 apartment homes located in College Park, Maryland and Irvine, California, for approximately $9.5 million. The acquisitions of the remaining ownership interests were recorded as equity transactions and, as a result, the carrying balances of the non-controlling interest were eliminated and the remaining difference between the purchase price and carrying balance was recorded as a reduction in additional paid-in capital. See Note 15, "Non-controlling Interests," for the effect of changes in ownership interests of these former joint ventures on the equity attributable to common shareholders.

Land Holding Dispositions. During the year ended December 31, 2017, we did not sell any land. During the year ended December 31, 2016, we sold approximately 6.3 acres of land adjacent to an operating property in Tampa, Florida for approximately $2.2 million and recognized a gain of approximately $0.4 million. During the year ended December 31, 2015, we sold two land holdings adjacent to operating properties in Dallas and Houston, Texas for approximately $1.1 million and recognized a gain of approximately $0.3 million.

Sale of Operating Properties.In December 2017, we soldoneoperating property, comprised of1,005apartment homes, located in Corpus Christi, Texas for approximately$78.4 millionand recognized a gain of approximately$43.2 million.

During the year ended December 31, 2016, we sold one dual-phased property and six other operating properties comprised of an aggregate of 3,184 apartment homes with an average age of 24 years, located in Landover and Frederick, Maryland; Fullerton, California; and Tampa, Altamonte Springs, and St. Petersburg, Florida for an aggregate of approximately $523.4 million, and recognized a gain of approximately $294.9 million. During the year ended December 31, 2015, we sold three operating properties, comprised of an aggregate of 1,376 apartment homes located in Brandon and Tampa, Florida and Austin, Texas for an aggregate of approximately $147.4 million and recognized a gain of approximately $104.0 million relating to these property sales.

Discontinued Operations. During the year ended December 31, 2017, we did not have any discontinued operations. During the years ended December 31, 2016 and 2015, we had discontinued operations related to the sale in April 2016 of 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, net of closing costs. There were no additional discontinued operations during the year ended December 31, 2015.

F-18

The following is a summary of income from discontinued operations for the years ended December 31, 2016 and 2015 relating to the 15 operating properties and the retail center sold in April 2016:

8. Investments in Joint Ventures

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") at December 31, 2017, 2016, and 2015, with our ownership interest ranging from 20.0% to 31.3%. In March 2015, we completed the formation of a third fund with an unaffiliated third party for additional multifamily investments of up to $450.0 million. We have a 20.0% ownership interest in this third fund, and it did not own any properties in 2017, 2016, or 2015. 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)	2017		2016
Total assets	$	715.9	$	726.9
Total third-party debt	514.5		518.7
Total equity	174.5		184.0

	2017		2016		2015
Total revenues	$	121.9	$	119.8	$	114.5
Net income (1)	13.5		14.8		12.0
Equity in income (2) (3)	6.8		7.1		6.2

(1) Net income for the year ended December 31, 2017 includes approximately $1.3 million of property expense relating to Hurricanes Harvey and Irma in August and September 2017.

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

(3) Equity in income for the year ended December 31, 2017 includes our ownership interest of the hurricane related expenses of approximately $0.4 million.

The Funds in which we have a partial interest have been funded in part with secured third-party debt. As of December 31, 2017, 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 $5.8 million, $5.3 million, and $5.8 million for the years ended December 31, 2017, 2016, and 2015, respectively.

Value of real estate assets, at cost, subject to secured notes	$	1,534.9	$	1,598.9

(1) Unamortized debt discounts and debt issuance costs of $12.3 million and $15.7 million are included in senior unsecured and secured notes payable as of December 31, 2017 and 2016, respectively.

In August 2015, we amended and restated our $500 million unsecured credit facility, which extended the maturity date from September 2015 to August 2019, with two six-month options to extend the maturity date at our election to August 2020, and increased the availability to $600 million, with the option to further increase it 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 this 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 this 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 the credit facility. This 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 December 31, 2017, we had no balances outstanding on our $600 million credit facility and we had outstanding letters of credit totaling approximately $13.4 million, leaving approximately $586.6 million available under our credit facility.

In May 2017, we used cash and borrowings from our existing unsecured credit facility to repay the principal amount of our 5.83% senior unsecured note payable, which was scheduled to mature on May 15, 2017, for a total of $246.8 million, plus accrued interest. Also, in May 2017, we entered into a $45.0 million unsecured short-term borrowing facility which matures in May 2018. The interest rate is based on LIBOR plus 0.95%. At December 31, 2017, we had no balances outstanding on this unsecured short-term borrowing facility, leaving $45.0 million available under this facility.

In February 2017, we used available cash on-hand to repay our tax-exempt secured note payable of approximately $30.7 million, which was scheduled to mature in 2028. As a result of the early repayment, we expensed approximately $0.3 million of unamortized loan costs, which are reflected in the loss on early retirement of debt in our consolidated statements of income and comprehensive income.

At December 31, 2017 and 2016, we had outstanding floating rate debt of approximately $175.0 million and $205.7 million, respectively. The weighted average interest rate on this debt was approximately 1.9% and 1.4% for the years ended December 31, 2017 and 2016, respectively.

F-20

Our indebtedness had a weighted average maturity of 4.3 years at December 31, 2017. 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 December 31, 2017:

(in millions) (1)	Amount			Weighted Average Interest Rate
2018	$	173.7		1.9	%
2019	643.0			5.4
2020 (2)	(1.2		)	—
2021	249.1			4.8
2022	349.3			3.2
Thereafter	790.7			4.4
Total	$	2,204.6		4.3	%

(1) Includes all available extension options.

(2) Includes amortization of debt discounts and debt issuance costs, net of scheduled principal payments.

10. Derivative Financial Instruments and Hedging Activities

Risk Management Objective of Using Derivatives. We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of our debt funding and the use of derivative financial instruments. Specifically, we may enter into derivative financial instruments to manage exposures arising from business activities resulting in differences in the amount, timing, and duration of our known or expected cash payments principally related to our borrowings. See Note 2, "Summary of Significant Accounting Policies and Recent Accounting Pronouncements" for a further discussion of derivative financial instruments.

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

Designated Hedges. Effective with our adoption of ASU 2017-12, the gain or loss on the derivatives designated and qualifying as cash flow hedges is reported as a component of other comprehensive income or loss and subsequently reclassified into earnings in the period the hedged forecasted transaction affects earnings and presented in the same line item as the earnings effect of the hedged item. At December 31, 2017, we had a total of three designated hedges outstanding with a total notional value of $200.0 million. In August 2017, we entered into a forward interest rate swap agreement with a notional amount of $100.0 million that becomes effective October 31, 2018 to hedge a portion of an anticipated future fixed rate debt issuance. In November 2017, we entered into two forward interest swap agreements with a notional amount of $50.0 million each and both become effective October 31, 2018 to hedge a portion of anticipated future fixed rate debt issuances. As of December 31, 2017, the amount expected to be reclassified into earnings in the next 12 months as a decrease to interest expense is immaterial. See Note 13, "Fair Value Measurements" for a further discussion of the fair value of our derivative financial instrument.

Non-Designated Hedges. Derivatives are not entered into for trading or speculative purposes and are used to manage our exposure to interest rate movements and other identified risks. Our non-designated hedges are either specifically non-designated by management or do not meet strict hedge accounting requirements. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings in interest and other income. At December 31, 2017, we did not have any non-designated hedges outstanding. At December 31, 2016, we had one outstanding interest rate cap with a notional amount of $175.0 million which was not designated as a hedge of interest rate risk. The fair value changes for this derivative was not material.

The table below presents the fair value of our derivative financial instruments as well as their classification in the consolidated balance sheets at December 31, 2017:

F-21

	Asset Derivatives			Liability Derivatives
(in millions)	Balance Sheet Location	Fair Value		Balance Sheet Location	Fair Value
Derivatives designated as hedging instruments
Interest Rate Swaps	Other Assets	$	2.2	Other Liabilities	$	0.5

The table below presents the effect of our derivative financial instruments in the consolidated statements of income (loss) and comprehensive income for the year ended December 31, 2017:

Derivatives in Cash Flow Hedging Relationships	Unrealized Gain Recognized in Other Comprehensive  Income (“OCI”) on  Derivatives		Location of Gain Reclassified from Accumulated OCI into Income	Amount of Gain Reclassified from Accumulated OCI into Income
	2017			2017
Interest Rate Swaps	$	1.7	Interest expense	N/A

Credit-Risk-Related Contingent Features. Derivative financial investments expose us to credit risk in the event of non-performance by the counterparties under the terms of the interest rate hedge agreements. The Company has agreements with derivative counterparties that contain provisions where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company's default on the indebtedness. As of December 31, 2017, the fair value of derivatives in a net liability position, which excludes any adjustment for nonperformance risk, related to these agreements was approximately $0.5 million.

11. Share-based Compensation and Benefit Plans

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 December 31, 2017, approximately 2.9 million fungible units were available under the 2011 Share Plan, which results in approximately 0.8 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 plan, in increments ranging from 20% to 33.33% per year on each of the anniversaries of the date of grant. The plan provides that the exercise price of an option will be determined by the Compensation Committee of the Board of Trust Managers on the day of grant, and to date all options have been granted at an exercise price that equals the fair market value on the date of grant. Approximately 0.1 million, 0.2 million and 0.1 million options were exercised during the years ended December 31, 2017, 2016, and 2015, respectively. The total

F-22

intrinsic value of options exercised was approximately $2.2 million, $8.9 million, and $2.0 million during the years ended December 31, 2017, 2016 and 2015, respectively. At December 31, 2017, there was no unrecognized compensation cost related to unvested options. At December 31, 2017, all options outstanding were exercisable and had a weighted average remaining life of approximately 1.1 years.

The following table summarizes outstanding share options, all of which were exercisable, at December 31, 2017:

	Options Outstanding and Exercisable (1)
Exercise Prices	Number	Weighted Average Price
$30.06	26,114	$	30.06
$75.17	15,388	75.17
$80.89 - $85.05	27,476	82.84
Total options	68,978	$	61.15

(1) The aggregate intrinsic value of options outstanding and exercisable at December 31, 2017 was approximately $2.1 million. The aggregate intrinsic value was calculated as the excess, if any, between our closing share price of $92.06 per share on December 31, 2017 and the strike price of the underlying award.

Options Granted and Valuation Assumptions. During the years ended December 31, 2017, 2016, and 2015, we granted approximately 15 thousand, 13 thousand and 27 thousand reload options, respectively. 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 years ended December 31, 2017, 2016 and 2015 vested immediately. Approximately $0.1 million was expensed in both 2017 and 2016, and approximately $0.2 million was expensed in 2015 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 years ended December 31, 2017, 2016 and 2015:

	Year Ended December 31, 2017	Year Ended December 31, 2016	Year Ended December 31, 2015
Weighted average fair value of options granted	$5.25	$6.71	$5.52 - $7.38
Expected volatility	18.9%	18%	16.5% - 18.8%
Risk-free interest rate	1.3%	0.9%	1.0% - 1.3%
Expected dividend yield	5.5%	3.8%	3.5% - 3.7%
Expected life	2 years	3 years	3 years - 4 years

Our computations of expected volatility for 2017, 2016, and 2015 are 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. Effective with our adoption of ASU 2016-09 on January 1, 2017, we utilize actual forfeitures rather than estimating forfeitures at the time share-based awards were granted. See Note 2, "Summary of Significant Accounting Policies and Recent Accounting Pronouncements," for a further discussion of the adoption and impact of ASU 2016-09 on our consolidated financial statements. At December 31, 2017, the unamortized value of previously issued unvested share awards was approximately $19.9 million which is expected to be amortized over the next two years. The total fair value of shares vested during the years ended December 31, 2017, 2016 and 2015 was approximately $23.1 million, $27.2 million, and $19.2 million, respectively.

Total compensation cost for option and share awards charged against income was approximately $18.8 million, $21.3 million, and $18.6 million for 2017, 2016 and 2015, respectively. Total capitalized compensation cost for option and share

F-23

awards was approximately $3.8 million each of the years ended December 31, 2017 and 2016, and was $3.5 million for the year ended December 31, 2015.

The following table summarizes activity under our share incentive plans for the three years ended December 31:

	Options Outstanding		Weighted Average Exercise  / Grant Price		Nonvested Share Awards Outstanding		Weighted Average Exercise  / Grant Price

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

	2017		2016		2015
Shares purchased	18,986		20,797		14,655
Weighted average fair value of shares purchased	$	89.89	$	82.33	$	74.66
Expense recorded (in millions)	$	0.3	$	0.4	$	0.2

Rabbi Trust. We established a rabbi trust for a select group of participants in which share awards granted under the share incentive plan and salary and other cash amounts earned may be deposited. The rabbi trust is only in use for deferrals made prior to 2005, including bonuses related to service in 2004 but paid in 2005. The rabbi trust is an irrevocable trust and no portion of the trust fund may be used for any purpose other than the delivery of those assets to the participants. The assets held in the rabbi trust are subject to the claims of our general creditors in the event of bankruptcy or insolvency.

The value of the assets of the rabbi trust is consolidated into our financial statements. Granted share awards held by the rabbi trust are classified in equity in a manner similar to the manner in which treasury stock is accounted. Subsequent changes in the fair value of the shares are not recognized. The deferred compensation obligation is classified as an equity instrument and changes in the fair value of the amount owed to the participant are not recognized. At December 31, 2017 and 2016, approximately 1.7 million and 1.8 million share awards were held in the rabbi trust, respectively. Additionally, as of December 31, 2017 and 2016, the rabbi trust held trading securities totaling approximately $26.7 million and $34.5 million, respectively, which represents cash deferrals made by plan participants. Market value fluctuations on these trading securities are recognized in income in accordance with GAAP and the liability due to participants is adjusted accordingly.

At December 31, 2017 and 2016, approximately $22.3 million and $22.7 million, respectively, was required to be paid to us by plan participants upon the withdrawal of any assets from the rabbi trust, and is included in “Accounts receivable-affiliates” in our consolidated financial statements.

Non-Qualified Deferred Compensation Share Awards. In 2004, we established a Non-Qualified Deferred Compensation Plan which is an unfunded arrangement established and maintained primarily for the benefit of a select group of

F-24

participants. Eligible participants commence participation in this plan on the date the deferral election first becomes effective. We credit to the participant's account an amount equal to the amount designated as the participant's deferral for the plan year as indicated in the participant's deferral election(s). Any modification to or termination of the plan will not reduce a participant's right to any vested amounts already credited to his or her account. Approximately 1.0 million and 1.1 million share awards were held in the plan at December 31, 2017 and 2016, respectively. Additionally, as of December 31, 2017 and 2016, the plan held trading securities totaling approximately $93.6 million and $59.5 million, respectively, which represents cash deferrals made by plan participants and diversification of share awards within the plan to trading securities. Market value fluctuations on these trading securities are recognized in income in accordance with GAAP and the liability due to participants is adjusted accordingly. The assets held in the Non-Qualified Deferred Compensation Plan are subject to the claims of our general creditors in the event of bankruptcy or insolvency.

The plan, as amended, permits diversification of fully vested share awards into other equity securities subject to a six month holding period. Balances within temporary equity in our consolidated balance sheets relate to fully vested awards and the proportionate share of nonvested awards of participants within our Non-Qualified Deferred Compensation Plan who are permitted to diversify their shares into other equity securities.

The following table summarizes the eligible share award activity for the twelve months ended December 31:

(in thousands)	2017			2016
Temporary equity:
Balance at inception/beginning of period	$	77,037		$	79,364

Balance at December 31	$	77,230		$	77,037

401(k) Savings Plan. We have a 401(k) savings plan, which is a voluntary defined contribution plan. Under the savings plan, every employee is eligible to participate, beginning on the date the employee has completed six months of continuous service with us. Each participant may make contributions to the savings plan by means of a pre-tax salary deferral, which may not be less than 1% or more than 60% of the participant’s compensation, subject to limitations. The federal tax code limits the annual amount of salary deferrals which may be made by any participant. We may make matching contributions on the participant’s behalf up to a predetermined limit. The matching contribution made for each of the years ended December 31, 2017 and 2016 was approximately $2.7 million, and was$2.6 millionfor the year ended December 31,2015. A participant’s salary deferral contribution is 100% vested and nonforfeitable. A participant will become vested in our matching contributions 33% after one year of service, 67% after two years of service and 100% after three years of service. Administrative expenses under the savings plan were paid by us and were not significant for all periods presented.

(1) Approximately $4.2 million and $8.3 million of participant cash was withdrawn from our deferred compensation plan investments during the years ended December 31, 2017 and 2016, respectively. Approximately $23.2 million and $25.4 million of shares within the deferred compensation plan were diversified into other deferred compensation plan investments during the years ended December 31, 2017 and 2016, respectively.

Nonrecurring Fair Value Disclosures. The nonrecurring fair value disclosures inputs under the fair value hierarchy are discussed in Note 2, “Summary of Significant Accounting Policies and Recent Accounting Pronouncements.” We completed an asset acquisition, Camden Buckhead Square, in 2017. We recorded the real estate assets and identifiable below market and in-place leases at their relative fair values based upon methods similar to those used by independent appraisers of income producing properties. The fair value measurements associated with the valuation of this acquired asset represent Level 3 measurements within the fair value hierarchy. See Note 7, "Acquisitions, Dispositions, and Discontinued Operations" for a further discussion about this acquisition. There were no non-recurring fair value adjustments during the year ended December 31, 2016.

14. Commitments and Contingencies

Construction Contracts. As of December 31, 2017, we estimate the additional cost to complete the seven consolidated projects currently under construction to be approximately $282.3 million. We expect to fund this amount through a combination of one or more of the following: cash and cash equivalents, cash flows generated from operations, draws on our unsecured credit facility or other short-term borrowing, the use of debt and equity offerings under our automatic shelf registration statement, proceeds from property dispositions, equity issued from our 2017 ATM program, other unsecured borrowings or secured mortgages.

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

Other 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 December 31, 2017, we had $5.2 million in refundable earnest money deposits for potential acquisitions of operating properties and land which are included in other assets, net in our consolidated balance sheet. Of this $5.2 million in refundable earnest money deposits, $5.0 million was related to acquisitions of operating properties in St. Petersburg and Orlando, Florida which were completed in January and February 2018.

Lease Commitments. At December 31, 2017, we had long-term leases covering certain land, office facilities and equipment. Rental expense totaled approximately $4.0 million, $4.1 million, and $3.4 million for the years ended December 31, 2017, 2016 and 2015, respectively. Minimum annual rental commitments for the years ending December 31, 2018 through 2022 are approximately $2.9 million, $2.8 million, $2.8 million, $2.8 million and $2.6 million, respectively, and approximately $6.7 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

F-27

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.

Employment Agreements. At December 31, 2017, we had employment agreements with 13 of our senior officers, the terms of which expire at various times through August 20, 2018. Such agreements provide for minimum salary levels as well as various incentive compensation arrangements, which are payable based on the attainment of specific goals. The agreements also provide for severance payments plus a gross-up payment if certain situations occur, such as termination without cause or a change of control. In the case of 10 of the agreements, the severance payment equals one times the respective current annual base salary in the case of termination without cause and 2.99 times the respective average annual base salary over the previous three fiscal years in the case of a change of control and a termination of employment or a material adverse change in the scope of their duties. In the case of one agreement, the severance payment equals one times the respective current annual base salary for termination without cause and 2.99 times the greater of current gross income or average gross income over the previous three fiscal years in the case of a change of control. In the case of the other two agreements, the severance payment generally equals 2.99 times the respective average annual compensation over the previous three fiscal years in connection with, among other things, a termination without cause or a change of control, and the officer would be entitled to receive continuation and vesting of certain benefits in the case of such termination.

Hurricanes. In August 2017, Hurricane Harvey impacted certain multifamily communities within our Texas portfolio. In September 2017, Hurricane Irma impacted certain multifamily communities throughout the state of Florida, and in the Atlanta, Georgia and Charlotte, North Carolina areas. We incurred approximately $3.9 million of expenses at our wholly-owned multifamily communities impacted by these hurricanes which is recorded in property operating and maintenance expenses, with no insurance recoveries anticipated. We also incurred approximately $0.7 million in other storm-related expenses relating to these hurricanes, which are recorded in general and administrative expenses. Additionally, we recognized $0.4 million, representing our share of ownership interest of hurricane-related expenses incurred by the multifamily communities of the Fund which is recorded in equity in income of joint ventures.

Business. Formed on May 25, 1993, Camden Property Trust, a Texas real estate investment trust (“REIT”), is primarily engaged in the ownership, management, development, redevelopment, acquisition, and construction of multifamily apartment communities. Our multifamily apartment communities are referred to as “communities,” “multifamily communities,” “properties,” or “multifamily properties” in the following discussion. As of December 31, 2017, we owned interests in, operated, or were developing 162 multifamily properties comprised of 55,143 apartment homes across the United States. Of the 162 properties, seven properties were under construction, and will consist of a total of 2,110 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 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. In determining if we have a controlling financial interest, we consider factors such as ownership interests, authority to make decisions, kick-out rights and participating rights. At December 31, 2017, 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 continue to consolidate these operating partnerships.

Acquisitions of Real Estate. Upon acquisition of real estate, we determine the fair value of tangible and intangible assets, which includes land, buildings (as-if-vacant), furniture and fixtures, the value of in-place leases, including above and below market leases, and acquired liabilities. In estimating these values, we apply methods similar to those used by independent appraisers of income-producing property. Upon our adoption of Accounting Standard Update 2017-01 ("ASU 2017-01") on January 1, 2017, as discussed below in Recent Accounting Pronouncements, we believe most future transaction costs relating to acquisition of operating assets will be capitalized. Prior to our adoption of ASU 2017-01 transaction costs associated with the acquisition of operating assets were expensed as incurred. Estimates of fair value of acquired debt are based upon interest rates available for the issuance of debt with similar terms and remaining maturities. Depreciation is computed on a straight-line basis over the remaining useful lives of the related tangible assets. The value of in-place leases and above or below market leases is amortized over the estimated average remaining life of leases in place at the time of acquisition. The net carrying value of below market leases is included in other liabilities in our consolidated balance sheets and the net carrying value of in-place leases is included in other assets, net in our consolidated balance sheets.

During the year ended December 31, 2017, we recognized amortization expense related to in-place leases of approximately $1.3 million. During the year ended December 31,2015, we recognized revenues related to below market leases of approximately $0.1 million and amortization expense related to in-place leases of approximately $0.5 million. We did not recognize any revenue or amortization expense related to below market or in-place leases for the year ended December 31, 2016.

The weighted average amortization period of in-place leases was approximately six months for the year ended December 31, 2017. The weighted average amortization period of below market leases and in-place leases were approximately eight months for the year ended December 31, 2015.

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 undiscounted cash flows, trends, strategic decisions regarding future development plans, and other factors in our assessment of whether impairment conditions exist. While we believe our estimates of future cash flows are reasonable, different assumptions regarding a number of factors, including market rents, economic conditions, and occupancies, could significantly affect these estimates. In estimating fair value, management uses appraisals, management estimates, and discounted cash flow calculations which 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 years ended December 31, 2017, 2016, or 2015.

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

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

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

Short-term Investments. Our short-term investments consisted of certificates of deposit which have original maturities of more than three months but less than one year.

Cost Capitalization. Real estate assets are carried at cost plus capitalized carrying charges. Carrying charges are primarily interest and real estate taxes which are capitalized as part of properties under development. Capitalized interest is generally based on the weighted average interest rate of our unsecured debt. Expenditures directly related to the development and improvement of real estate assets are capitalized at cost as land and buildings and improvements. Indirect development costs, including salaries and benefits and other related costs directly attributable to the development of properties, are also capitalized. We begin capitalizing development, construction, and carrying costs when the development of the future real estate asset is probable and activities necessary to 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. As apartment homes within development properties are completed, the total capitalized development cost of each apartment home is transferred from properties under development including land to buildings and improvements.

As discussed above, carrying charges are principally interest and real estate taxes capitalized as part of properties under development. Capitalized interest was approximately $15.2 million, $18.2 million, and $19.3 million for the years ended December 31, 2017, 2016, and 2015, respectively. Capitalized real estate taxes were approximately $2.4 million, $4.5 million, and $3.6 million for the years ended December 31, 2017, 2016, and 2015, respectively.

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

We also incur expenditures related to renovation and construction of office space we lease and we capitalize these leasehold improvements as furniture, fixtures, equipment and other. We depreciate these costs using the straight-line method over the shorter of the lease term or the useful life of the improvement.

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

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

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

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 during the period 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 consolidated balance sheets. Subsequent to classification of a property as held for sale, no further depreciation is recorded. Consolidated operating properties sold or classified as held for sale, which do not meet the above criteria of discontinued operations are not included in discontinued operations and the related gains and losses are included in continuing operations. 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 accounting principles generally accepted in the United States of America ("GAAP"), provided various criteria relating to the terms of sale and any subsequent involvement with the real estate sold are satisfied.

See Note 7, "Acquisitions, Dispositions, and Discontinued Operations," for discussion of discontinued operations for the year ended December 31, 2016. There were no discontinued operations for the years ended 2017 or 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 receive to sell an asset, or pay to transfer a liability, in an orderly transaction with a market participant at the measurement date. In the absence of such data, fair value is estimated using internal information consistent with what market participants would use in a hypothetical transaction.

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

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

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

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

Recurring Fair Value Measurements. The following describes the valuation methodologies we use to measure different financial instruments at fair value on a recurring basis:

Deferred Compensation Plan Investments. The estimated fair values of investment securities classified as deferred compensation plan investments are based on quoted market prices utilizing public information for the same transactions. Our deferred compensation plan investments are recorded in other assets in our 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.

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

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

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 December 31, 2017 and 2016, 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 value of our notes receivable, which are included in other assets, net in our consolidated balance sheets, approximates their fair value. The estimated fair values 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.

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

Reclassifications. Certain reclassifications have been made to amounts in prior period financial statements to conform to the current period presentation. We reclassified certain insignificant amounts in the consolidated statements of cash flows for the years ended December 31, 2016 and 2015. These reclassifications had no impact on our consolidated cash flows from operating, investing or financing activities.

Insurance. Our primary lines of insurance coverage are property, general liability, health, and workers’ compensation. We believe our insurance coverage adequately insures our properties against the risk of loss attributable to fire, earthquake, hurricane, tornado, flood, and other perils and adequately insures us against other risks. Losses are accrued based upon our estimates of the aggregate liability for claims incurred using certain actuarial assumptions followed in the insurance industry and based on our experience.

Other Assets, Net. Other assets in our consolidated financial statements include investments under deferred compensation plans, deferred financing costs, non-real estate leasehold improvements and equipment, notes receivable, prepaid expenses, the value of in-place leases net of related accumulated amortization, and other miscellaneous receivables. Investments under deferred compensation plans are classified as trading securities and are adjusted to fair market value at period end. For a further discussion of our investments under deferred compensation plans, see Note 11, “Share-based Compensation and Benefit Plans.” Deferred financing costs are related to our unsecured credit facility and unsecured short-term borrowing facility, and are amortized no longer than the terms of the related facilities on the straight-line method, which approximates the effective interest method. Corporate leasehold improvements and equipment are depreciated using the straight-line method over the shorter of the expected useful lives or the lease terms which generally range from three to ten years.

Our notes receivable relate to real estate secured loans to unaffiliated third parties. At December 31, 2017 and 2016, we had one outstanding note receivable balance of approximately $18.8 million and $17.2 million, respectively. The weighted average interest rates were approximately 4.0% for each of the years ended December 31, 2017 and 2016 related to such note. At December 31, 2017, construction was complete on this project and we were not committed to fund any additional amounts under the note. Interest is recognized over the life of the note 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. All cash receipts on impaired notes are applied to reduce the principal amount of such notes until the principal has been recovered and, thereafter, are recognized as interest income. There were no impairments as of December 31, 2017 or 2016.

Reportable Segments. We operate in a single reportable segment which includes the ownership, management, development, redevelopment, acquisition, and construction of multifamily apartment communities. Each of our operating properties is considered a separate operating segment as each property earns revenues and incurs expenses, individual operating results are reviewed and discrete financial information is available. We do not distinguish or group our consolidated operations based on geography, size or type. Our multifamily apartment communities have similar long-term economic characteristics and provide similar products and services to our residents. Further, all material operations are within the United States and no multifamily apartment community comprises more than 10% of consolidated revenues. As a result, our operating properties are aggregated into a single reportable segment. Our multifamily communities generate rental revenue and other income through the leasing of apartment homes, which comprised approximately 99% of our total property revenues and total non-property income, excluding income on deferred compensation plans, for each of the years ended December 31, 2017, 2016, and 2015.

Restricted Cash. Restricted cash consists of escrow deposits held by lenders for property taxes, insurance and replacement reserves, cash required to be segregated for the repayment of residents’ security deposits, and escrowed amounts related to our development and acquisition activities. Substantially all restricted cash is invested in demand and short-term instruments.

Share-based Compensation. Compensation expense associated with share-based awards is recognized in our consolidated statements of income and comprehensive income using the grant-date fair values. Compensation cost for all share-based awards, including options, requires measurement at estimated fair value on the grant date and recognition of compensation expense over the requisite service period for awards expected to vest. The fair value of stock option grants is estimated using the Black-Scholes valuation model. Valuation models require the input of assumptions, including judgments to estimate the expected stock price volatility, expected life, and forfeiture rate. The compensation cost for share-based awards is based on the market value of the shares on the date of grant.

Use of Estimates. In the application of GAAP, management is required to make estimates and assumptions which affect the reported amounts of assets and liabilities at the date of the financial statements, results of operations during the reporting periods, and related disclosures. Our more significant estimates include estimates supporting our impairment analysis related to the carrying values of our real estate assets. These estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances. Future events rarely develop exactly as forecasted, and the best estimates routinely require adjustment.

Recent Accounting Pronouncements. In January 2017, the Financial Accounting Standards Board ("FASB") issued ASU 2017-01, "Clarifying the Definition of a Business (Topic 805)." ASU 2017-01 clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. ASU 2017-01 is effective for interim and annual periods beginning after December 15, 2017, early adoption was permitted, and we adopted ASU 2017-01 as of January 1, 2017. We believe most of our future acquisitions of operating properties will qualify as asset acquisitions and most future transaction costs associated with these acquisitions will be capitalized.

In February 2017, the FASB issued ASU 2017-05, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets." ASU 2017-05 clarifies the definition of an in-substance nonfinancial asset and changes the accounting for partial sales of nonfinancial assets to be more consistent with the accounting for a sale of a business pursuant to ASU 2017-01. This update is effective for interim and annual periods beginning after December 15, 2017 using a full retrospective or modified retrospective method and is required to be adopted in conjunction with ASU 2014-09, "Revenue from Contracts with Customers" discussed below. We adopted ASU 2017-05 as of January 1, 2018, along with our adoption of ASU 2014-09, using the modified retrospective method and it did not have a material impact on our consolidated financial statements. We believe most of our future contributions of nonfinancial assets to our joint ventures, if any, will result in the recognition of a full gain or loss as if we sold 100% of the nonfinancial asset and we will also measure our retained interest at fair value.

In May 2014, the FASB issued ASU 2014-09 which prescribes a single, common revenue standard to replace most existing revenue recognition guidance in GAAP, including most industry-specific requirements. The standard outlines a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied. Several ASUs have been issued since the issuance of ASU 2014-09 which modify certain sections of the new revenue recognition standard, and are intended to promote a more consistent interpretation and application of the principles outlined in the standard. We adopted ASU 2014-09, and all related amendments, effective January 1, 2018 using the modified retrospective with cumulative-effect transition method which requires us to recognize the cumulative effect of initially applying the new revenue standard as an adjustment, if any, to the opening balance of retained earnings. We have identified our revenue streams and finalized our evaluation of the impact on our consolidated financial statements and internal accounting processes. Upon adoption, we will present certain revenue streams, which are currently included as a component of our other property revenues, as rental revenues due to the nature and timing of revenue recognition for these revenue streams. The new presentation will be applied prospectively upon adoption as this adjustment will not have an impact upon total property revenues or the opening balance of retained earnings and the adoption of ASU 2014-09 and its related amendments will not have a material impact on our consolidated financial statements as the majority of our revenue is derived from real estate lease contracts. Had ASU 2014-09 been effective as of January 1, 2017, we would have reclassified approximately $21.9 million from other property revenue to rental revenue for the year end December 31, 2017.

In February 2016, the FASB issued ASU 2016-02, "Leases." ASU 2016-02 supersedes the current accounting for leases and while retaining two distinct types of leases, finance and operating, (i) requires lessees to record a right of use asset and a related liability for the rights and obligations associated with a lease, regardless of lease classification, and recognize lease expense in a manner similar to current accounting (ii) eliminates most real estate specific lease provisions, and (iii) aligns many of the underlying lessor model principles with those in the new revenue standard. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. We are required to adopt ASU 2016-02 using the modified retrospective approach which requires us to record leases existing as of or are entered into after the beginning of the earliest comparative period presented in the financial statements under the new lease standard. We anticipate adopting ASU 2016-02 as of January 1, 2019. Based on our assessments, most of our operating lease commitments will be subject to the new guidance and recognized as operating lease liabilities and right-of-use assets upon adoption and believe our adoption of the new leasing standard will have an immaterial increase in the assets and liabilities on our consolidated balance sheets, with no material impact to our consolidated statements of income and comprehensive income. However, the ultimate impact will depend on our lease portfolio as of the adoption date.

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 we adopted ASU 2016-09 as of January 1, 2017. Upon adoption we elected to recognize forfeitures of share-based payment awards as they occur, rather than estimating forfeitures at the time awards are granted. Historically, our estimated forfeitures approximated actual forfeitures and the impact of the change in policy upon our adoption of ASU 2016-09 did not have a material impact on our consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, "Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)." ASU 2016-15 clarifies how eight 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 retrospectively. We adopted ASU 2016-15 as of January 1, 2018 using the retrospective method by applying the cumulative earnings approach to classify distributions received from our equity method investees and it did not have a material effect on our consolidated statements of cash flows upon adoption.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." ASU 2017-12 amends the hedge accounting model to provide better insight to risk management activities in the financial statements, reduces the complexity in cash flow hedges of interest rate risk, eliminates the requirement to separately measure and report hedge ineffectiveness, requires the entire change in the fair value of a hedging instrument included in the assessment of the hedge effectiveness to be recorded in other comprehensive income, with amounts reclassified to earnings to be presented in the same line item used to present the earnings effect of the hedged item when the hedged item affects earnings and allows the initial prospective quantitative assessment of hedge effectiveness to be performed at any time after hedge designation, but no later than the first quarterly effectiveness testing date. ASU 2017-12 is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The amendments in this standard must be applied using the modified retrospective approach for cash flow and net investment hedge relationships existing on the date of adoption. We adopted ASU 2017-12 in the third quarter of 2017, and this adoption had no impact upon adoption as we had no hedging activities in the prior periods presented.

Earnings Per Share [Abstract]

Per Share Data

3. Per Share Data

Basic earnings per share are computed using net income attributable to common shareholders and the weighted average number of common shares outstanding. Diluted earnings per share reflect common shares issuable from the assumed conversion of common share options and share awards granted and units convertible into common shares. Only those items having a dilutive impact on our basic earnings per share are included in diluted earnings per share. Our unvested share-based awards are considered participating securities and are reflected in the calculation of basic and diluted earnings per share using the two-class method. The number of common share equivalent securities excluded from the diluted earnings per share calculation was approximately 1.5 million, 2.4 million, and 2.6 million for the years ended December 31, 2017, 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 calculation as they are anti-dilutive.

Stockholders' Equity Note [Abstract]

Common Shares [Text Block]

4. Common Shares

In May 2017, we created an at-the market ("ATM") share offering program through which we can, but have no obligation to, sell common shares having an aggregate offering price of up to $315.3 million (the "2017 ATM program"), in amounts and at times as we determine, into the existing trading market at current market prices as well as through negotiated transactions. Actual sales from time to time may depend on a variety of factors including, among others, market conditions, the trading price of our common shares, and determinations by management of the appropriate sources of funding for us. The proceeds from the sale of our common shares under the 2017 ATM program are intended to be used for general corporate purposes, which may include reducing future borrowings under our $600 million unsecured line of credit, the repayment of other indebtedness, the redemption or other repurchase of outstanding debt or equity securities, funding for development activities, and financing for acquisitions.

The following table presents activity under the 2017 ATM program for the year ended December 31, 2017:

(in thousands, except per share amounts)	Year Ended December 31, 2017
Total net consideration	$	2,513.6
Common shares sold	28.1
Average price per share	$	90.44

As of the date of this filing, we had common shares having an aggregate offering price of up to $312.8 million remaining available for sale under the 2017 ATM program. No additional shares were sold under the 2017 ATM program subsequent to December 31, 2017 through the date of this filing.

In November 2014, we created an ATM share offering program through which we could, but had no obligation to, sell common shares having an aggregate offering price of up to $331.3 million (the "2014 ATM program"). Concurrently with the creation of the 2017 ATM program in May 2017 discussed above, we terminated the 2014 ATM program and rolled the $315.3 million remaining available for sale under the 2014 ATM program into the 2017 ATM program. Upon termination, no further common shares were available for sale under the 2014 ATM program.

We have a repurchase plan approved by our Board of Trust Managers which allows for the repurchase of up to $500 million of our common equity securities through open market purchases, block purchases, and privately negotiated transactions. 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. There were no repurchases for the years ended December 31, 2017, 2016, or 2015 under this program.

We currently have an automatic shelf registration statement which allows us to offer, from time to time, common shares, preferred shares, debt securities, or warrants. Our Amended and Restated Declaration of Trust provides we may issue up to 185 million shares of beneficial interest, consisting of 175 million common shares and 10 million preferred shares. At December 31, 2017, we had approximately 92.7 million common shares outstanding, net of treasury shares and shares held in our deferred compensation arrangements, and no preferred shares outstanding. In September 2017, we issued approximately 4.8 million common shares in a public equity offering and received approximately $442.5 million in net proceeds. We intend to use the net proceeds for general corporate purposes, which may include financing for acquisitions and funding for development activities, reducing borrowings under our $600 million unsecured line of credit, the repayment of indebtedness, and the redemption or other repurchase of outstanding debt or equity securities.

In addition to our 2016 quarterly dividends, 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 of gains on dispositions of assets completed in 2016, which was paid on September 30, 2016. We also paid equivalent amounts per unit to holders of the common operating partnership units.

Camden Operating has 11.9 million outstanding common limited partnership units and as of December 31, 2017, we held 92% of the outstanding common limited partnership units and the sole 1% general partnership interest of the operating partnership. The remaining common limited partnership units, comprising approximately 0.8 million units, are primarily held by former officers, directors, and investors of Paragon Group, Inc., which we acquired in 1997. Each common limited partnership unit is redeemable for one common share of Camden Property Trust or cash at our election. Holders of common limited partnership units are not entitled to rights as shareholders prior to redemption of their common limited partnership units. No member of our management owns Camden Operating common limited partnership units.

Income Tax Disclosure [Abstract]

Income Taxes

6. Income Taxes

We have maintained and intend to maintain our election as a REIT under the Internal Revenue Code of 1986, as amended. In order for us to continue to qualify as a REIT we must meet a number of organizational and operational requirements, including a requirement to distribute annual dividends to our shareholders equal to a minimum of 90% of our 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 for taxable years ended before January 1, 2018 any applicable alternative minimum tax. In addition, we may not be able to requalify as a REIT for the four subsequent taxable years. Historically, we have incurred only state and local income, franchise, and excise taxes. Taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to applicable federal, state, and local income taxes. Our operating partnerships are flow-through entities and are not subject to federal income taxes at the entity level.

We have recorded income, franchise, and excise taxes in the consolidated statements of income and comprehensive income for the years ended December 31, 2017, 2016 and 2015 as income tax expense. Income taxes for the years ended December 31, 2017, 2016 and 2015, 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.

For income tax purposes, distributions to common shareholders are characterized as ordinary income, capital gains or as a return of a shareholder's invested capital. A summary of the income tax characterization of our distributions paid per common share for the years ended December 31, 2017, 2016 and 2015 is set forth in the following table:

	Year Ended December 31,
	2017		2016		2015
Common Share Distributions
Ordinary income	$	2.38	$	—	$	1.88
Long-term capital gain	0.41		5.02		0.70
Unrecaptured Sec. 1250 gain	0.21		2.23		0.22
Total	$	3.00	$	7.25	$	2.80

We have taxable REIT subsidiaries which are subject to federal and state income taxes. At December 31, 2017, our taxable REIT subsidiaries had immaterial net operating loss carryforwards (“NOL’s”) which expire in years 2034 to 2037. Because NOL’s are subject to certain change of ownership, continuity of business, and separate return year limitations, and because we believe it is unlikely the available NOL’s will be utilized or if utilized, any amounts will be immaterial, no benefits related to these NOL’s have been recognized in our consolidated financial statements.

The carrying value of net assets reported in our consolidated financial statements at December 31, 2017 exceeded the tax basis by approximately $1.3 billion.

Income Tax Expense. For the tax year ended December 31, 2017, we had income tax expense of approximately $1.2 million, and $1.6 million and $1.9 million for the tax years ended December 31, 2016 and 2015, respectively. The income tax expense for the year ended December 31, 2017 also included a tax benefit which related to a state income tax refund received of approximately $0.5 million. Income tax for the years ended December 31, 2017, 2016, and 2015 was comprised mainly of state income tax and federal income tax related to one of our taxable REIT subsidiaries.

Income Tax Expense – Deferred. For the years ended December 31, 2017, 2016, and 2015, our deferred tax expense was not significant.

Camden Property Trust's and our subsidiaries’ income tax returns are subject to examination by federal, state and local tax jurisdictions for years 2014 through 2016. NOL's and other tax attributes generated in years prior to 2014 are also subject to challenge in any examination of those tax years. We believe we have no uncertain tax positions or unrecognized tax benefits requiring disclosure as of and for the periods presented.

Tax reform. The 2017 Tax Act was passed on December 22, 2017 which includes a number of changes to the corporate income tax system, including but not limited to a reduction in the statutory federal corporate income tax rate from 35% to 21% for non-REIT “C” corporations, changes to deductions for certain pass-through business income, and possible limitations on interest expense, depreciation and the deductibility of executive compensation. As a REIT, we generally will not be subject to federal income tax on our taxable income at the corporate level and do not believe any of the changes from the 2017 Tax Act will have a material impact on our consolidated financial statements.

The acquisitions of the remaining ownership interests were recorded as equity transactions and, as a result, the carrying balances of the non-controlling interest were eliminated and the remaining difference between the purchase price and carrying balance was recorded as a reduction in additional paid-in capital. See Note 15, "Non-controlling Interests," for the effect of changes in ownership interests of these former joint ventures on the equity attributable to common shareholders.

Investments In Joint Ventures

8. Investments in Joint Ventures

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") at December 31, 2017, 2016, and 2015, with our ownership interest ranging from 20.0% to 31.3%. In March 2015, we completed the formation of a third fund with an unaffiliated third party for additional multifamily investments of up to $450.0 million. We have a 20.0% ownership interest in this third fund, and it did not own any properties in 2017, 2016, or 2015. 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)	2017		2016
Total assets	$	715.9	$	726.9
Total third-party debt	514.5		518.7
Total equity	174.5		184.0

	2017		2016		2015
Total revenues	$	121.9	$	119.8	$	114.5
Net income (1)	13.5		14.8		12.0
Equity in income (2) (3)	6.8		7.1		6.2

(1) Net income for the year ended December 31, 2017 includes approximately $1.3 million of property expense relating to Hurricanes Harvey and Irma in August and September 2017.

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

(3) Equity in income for the year ended December 31, 2017 includes our ownership interest of the hurricane related expenses of approximately $0.4 million.

The Funds in which we have a partial interest have been funded in part with secured third-party debt. As of December 31, 2017, 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 $5.8 million, $5.3 million, and $5.8 million for the years ended December 31, 2017, 2016, and 2015, respectively.

(1) Unamortized debt discounts and debt issuance costs of $12.3 million and $15.7 million are included in senior unsecured and secured notes payable as of December 31, 2017 and 2016, respectively.

In August 2015, we amended and restated our $500 million unsecured credit facility, which extended the maturity date from September 2015 to August 2019, with two six-month options to extend the maturity date at our election to August 2020, and increased the availability to $600 million, with the option to further increase it 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 this 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 this 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 the credit facility. This 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 December 31, 2017, we had no balances outstanding on our $600 million credit facility and we had outstanding letters of credit totaling approximately $13.4 million, leaving approximately $586.6 million available under our credit facility.

In May 2017, we used cash and borrowings from our existing unsecured credit facility to repay the principal amount of our 5.83% senior unsecured note payable, which was scheduled to mature on May 15, 2017, for a total of $246.8 million, plus accrued interest. Also, in May 2017, we entered into a $45.0 million unsecured short-term borrowing facility which matures in May 2018. The interest rate is based on LIBOR plus 0.95%. At December 31, 2017, we had no balances outstanding on this unsecured short-term borrowing facility, leaving $45.0 million available under this facility.

In February 2017, we used available cash on-hand to repay our tax-exempt secured note payable of approximately $30.7 million, which was scheduled to mature in 2028. As a result of the early repayment, we expensed approximately $0.3 million of unamortized loan costs, which are reflected in the loss on early retirement of debt in our consolidated statements of income and comprehensive income.

At December 31, 2017 and 2016, we had outstanding floating rate debt of approximately $175.0 million and $205.7 million, respectively. The weighted average interest rate on this debt was approximately 1.9% and 1.4% for the years ended December 31, 2017 and 2016, respectively.

Our indebtedness had a weighted average maturity of 4.3 years at December 31, 2017. 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 December 31, 2017:

Derivative Financial Instruments and Hedging Activities (Notes)

Dec. 31, 2017

Derivative Financial Instruments and Hedging Activities [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

10. Derivative Financial Instruments and Hedging Activities

Risk Management Objective of Using Derivatives. We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of our debt funding and the use of derivative financial instruments. Specifically, we may enter into derivative financial instruments to manage exposures arising from business activities resulting in differences in the amount, timing, and duration of our known or expected cash payments principally related to our borrowings. See Note 2, "Summary of Significant Accounting Policies and Recent Accounting Pronouncements" for a further discussion of derivative financial instruments.

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

Designated Hedges. Effective with our adoption of ASU 2017-12, the gain or loss on the derivatives designated and qualifying as cash flow hedges is reported as a component of other comprehensive income or loss and subsequently reclassified into earnings in the period the hedged forecasted transaction affects earnings and presented in the same line item as the earnings effect of the hedged item. At December 31, 2017, we had a total of three designated hedges outstanding with a total notional value of $200.0 million. In August 2017, we entered into a forward interest rate swap agreement with a notional amount of $100.0 million that becomes effective October 31, 2018 to hedge a portion of an anticipated future fixed rate debt issuance. In November 2017, we entered into two forward interest swap agreements with a notional amount of $50.0 million each and both become effective October 31, 2018 to hedge a portion of anticipated future fixed rate debt issuances. As of December 31, 2017, the amount expected to be reclassified into earnings in the next 12 months as a decrease to interest expense is immaterial. See Note 13, "Fair Value Measurements" for a further discussion of the fair value of our derivative financial instrument.

Non-Designated Hedges. Derivatives are not entered into for trading or speculative purposes and are used to manage our exposure to interest rate movements and other identified risks. Our non-designated hedges are either specifically non-designated by management or do not meet strict hedge accounting requirements. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings in interest and other income. At December 31, 2017, we did not have any non-designated hedges outstanding. At December 31, 2016, we had one outstanding interest rate cap with a notional amount of $175.0 million which was not designated as a hedge of interest rate risk. The fair value changes for this derivative was not material.

The table below presents the fair value of our derivative financial instruments as well as their classification in the consolidated balance sheets at December 31, 2017:

	Asset Derivatives			Liability Derivatives
(in millions)	Balance Sheet Location	Fair Value		Balance Sheet Location	Fair Value
Derivatives designated as hedging instruments
Interest Rate Swaps	Other Assets	$	2.2	Other Liabilities	$	0.5

The table below presents the effect of our derivative financial instruments in the consolidated statements of income (loss) and comprehensive income for the year ended December 31, 2017:

Derivatives in Cash Flow Hedging Relationships	Unrealized Gain Recognized in Other Comprehensive  Income (“OCI”) on  Derivatives		Location of Gain Reclassified from Accumulated OCI into Income	Amount of Gain Reclassified from Accumulated OCI into Income
	2017			2017
Interest Rate Swaps	$	1.7	Interest expense	N/A

Credit-Risk-Related Contingent Features. Derivative financial investments expose us to credit risk in the event of non-performance by the counterparties under the terms of the interest rate hedge agreements. The Company has agreements with derivative counterparties that contain provisions where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company's default on the indebtedness. As of December 31, 2017, the fair value of derivatives in a net liability position, which excludes any adjustment for nonperformance risk, related to these agreements was approximately $0.5 million.

Share-based Compensation [Abstract]

Share-Based Compensation and Benefit Plans

11. Share-based Compensation and Benefit Plans

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 December 31, 2017, approximately 2.9 million fungible units were available under the 2011 Share Plan, which results in approximately 0.8 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 plan, in increments ranging from 20% to 33.33% per year on each of the anniversaries of the date of grant. The plan provides that the exercise price of an option will be determined by the Compensation Committee of the Board of Trust Managers on the day of grant, and to date all options have been granted at an exercise price that equals the fair market value on the date of grant. Approximately 0.1 million, 0.2 million and 0.1 million options were exercised during the years ended December 31, 2017, 2016, and 2015, respectively. The total intrinsic value of options exercised was approximately $2.2 million, $8.9 million, and $2.0 million during the years ended December 31, 2017, 2016 and 2015, respectively. At December 31, 2017, there was no unrecognized compensation cost related to unvested options. At December 31, 2017, all options outstanding were exercisable and had a weighted average remaining life of approximately 1.1 years.

The following table summarizes outstanding share options, all of which were exercisable, at December 31, 2017:

	Options Outstanding and Exercisable (1)
Exercise Prices	Number	Weighted Average Price
$30.06	26,114	$	30.06
$75.17	15,388	75.17
$80.89 - $85.05	27,476	82.84
Total options	68,978	$	61.15

(1) The aggregate intrinsic value of options outstanding and exercisable at December 31, 2017 was approximately $2.1 million. The aggregate intrinsic value was calculated as the excess, if any, between our closing share price of $92.06 per share on December 31, 2017 and the strike price of the underlying award.

Options Granted and Valuation Assumptions. During the years ended December 31, 2017, 2016, and 2015, we granted approximately 15 thousand, 13 thousand and 27 thousand reload options, respectively. 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 years ended December 31, 2017, 2016 and 2015 vested immediately. Approximately $0.1 million was expensed in both 2017 and 2016, and approximately $0.2 million was expensed in 2015 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 years ended December 31, 2017, 2016 and 2015:

	Year Ended December 31, 2017	Year Ended December 31, 2016	Year Ended December 31, 2015
Weighted average fair value of options granted	$5.25	$6.71	$5.52 - $7.38
Expected volatility	18.9%	18%	16.5% - 18.8%
Risk-free interest rate	1.3%	0.9%	1.0% - 1.3%
Expected dividend yield	5.5%	3.8%	3.5% - 3.7%
Expected life	2 years	3 years	3 years - 4 years

Our computations of expected volatility for 2017, 2016, and 2015 are 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. Effective with our adoption of ASU 2016-09 on January 1, 2017, we utilize actual forfeitures rather than estimating forfeitures at the time share-based awards were granted. See Note 2, "Summary of Significant Accounting Policies and Recent Accounting Pronouncements," for a further discussion of the adoption and impact of ASU 2016-09 on our consolidated financial statements. At December 31, 2017, the unamortized value of previously issued unvested share awards was approximately $19.9 million which is expected to be amortized over the next two years. The total fair value of shares vested during the years ended December 31, 2017, 2016 and 2015 was approximately $23.1 million, $27.2 million, and $19.2 million, respectively.

Total compensation cost for option and share awards charged against income was approximately $18.8 million, $21.3 million, and $18.6 million for 2017, 2016 and 2015, respectively. Total capitalized compensation cost for option and share awards was approximately $3.8 million each of the years ended December 31, 2017 and 2016, and was $3.5 million for the year ended December 31, 2015.

The following table summarizes activity under our share incentive plans for the three years ended December 31:

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

	2017		2016		2015
Shares purchased	18,986		20,797		14,655
Weighted average fair value of shares purchased	$	89.89	$	82.33	$	74.66
Expense recorded (in millions)	$	0.3	$	0.4	$	0.2

Rabbi Trust. We established a rabbi trust for a select group of participants in which share awards granted under the share incentive plan and salary and other cash amounts earned may be deposited. The rabbi trust is only in use for deferrals made prior to 2005, including bonuses related to service in 2004 but paid in 2005. The rabbi trust is an irrevocable trust and no portion of the trust fund may be used for any purpose other than the delivery of those assets to the participants. The assets held in the rabbi trust are subject to the claims of our general creditors in the event of bankruptcy or insolvency.

The value of the assets of the rabbi trust is consolidated into our financial statements. Granted share awards held by the rabbi trust are classified in equity in a manner similar to the manner in which treasury stock is accounted. Subsequent changes in the fair value of the shares are not recognized. The deferred compensation obligation is classified as an equity instrument and changes in the fair value of the amount owed to the participant are not recognized. At December 31, 2017 and 2016, approximately 1.7 million and 1.8 million share awards were held in the rabbi trust, respectively. Additionally, as of December 31, 2017 and 2016, the rabbi trust held trading securities totaling approximately $26.7 million and $34.5 million, respectively, which represents cash deferrals made by plan participants. Market value fluctuations on these trading securities are recognized in income in accordance with GAAP and the liability due to participants is adjusted accordingly.

At December 31, 2017 and 2016, approximately $22.3 million and $22.7 million, respectively, was required to be paid to us by plan participants upon the withdrawal of any assets from the rabbi trust, and is included in “Accounts receivable-affiliates” in our consolidated financial statements.

Non-Qualified Deferred Compensation Share Awards. In 2004, we established a Non-Qualified Deferred Compensation Plan which is an unfunded arrangement established and maintained primarily for the benefit of a select group of participants. Eligible participants commence participation in this plan on the date the deferral election first becomes effective. We credit to the participant's account an amount equal to the amount designated as the participant's deferral for the plan year as indicated in the participant's deferral election(s). Any modification to or termination of the plan will not reduce a participant's right to any vested amounts already credited to his or her account. Approximately 1.0 million and 1.1 million share awards were held in the plan at December 31, 2017 and 2016, respectively. Additionally, as of December 31, 2017 and 2016, the plan held trading securities totaling approximately $93.6 million and $59.5 million, respectively, which represents cash deferrals made by plan participants and diversification of share awards within the plan to trading securities. Market value fluctuations on these trading securities are recognized in income in accordance with GAAP and the liability due to participants is adjusted accordingly. The assets held in the Non-Qualified Deferred Compensation Plan are subject to the claims of our general creditors in the event of bankruptcy or insolvency.

The plan, as amended, permits diversification of fully vested share awards into other equity securities subject to a six month holding period. Balances within temporary equity in our consolidated balance sheets relate to fully vested awards and the proportionate share of nonvested awards of participants within our Non-Qualified Deferred Compensation Plan who are permitted to diversify their shares into other equity securities.

The following table summarizes the eligible share award activity for the twelve months ended December 31:

(in thousands)	2017			2016
Temporary equity:
Balance at inception/beginning of period	$	77,037		$	79,364

Balance at December 31	$	77,230		$	77,037

401(k) Savings Plan. We have a 401(k) savings plan, which is a voluntary defined contribution plan. Under the savings plan, every employee is eligible to participate, beginning on the date the employee has completed six months of continuous service with us. Each participant may make contributions to the savings plan by means of a pre-tax salary deferral, which may not be less than 1% or more than 60% of the participant’s compensation, subject to limitations. The federal tax code limits the annual amount of salary deferrals which may be made by any participant. We may make matching contributions on the participant’s behalf up to a predetermined limit. The matching contribution made for each of the years ended December 31, 2017 and 2016 was approximately $2.7 million, and was$2.6 millionfor the year ended December 31,2015. A participant’s salary deferral contribution is 100% vested and nonforfeitable. A participant will become vested in our matching contributions 33% after one year of service, 67% after two years of service and 100% after three years of service. Administrative expenses under the savings plan were paid by us and were not significant for all periods presented.

Approximately $23.2 million and $25.4 million of shares within the deferred compensation plan were diversified into other deferred compensation plan investments during the years ended December 31, 2017 and 2016, respectively.

Nonrecurring Fair Value Disclosures. The nonrecurring fair value disclosures inputs under the fair value hierarchy are discussed in Note 2, “Summary of Significant Accounting Policies and Recent Accounting Pronouncements.” We completed an asset acquisition, Camden Buckhead Square, in 2017. We recorded the real estate assets and identifiable below market and in-place leases at their relative fair values based upon methods similar to those used by independent appraisers of income producing properties. The fair value measurements associated with the valuation of this acquired asset represent Level 3 measurements within the fair value hierarchy. See Note 7, "Acquisitions, Dispositions, and Discontinued Operations" for a further discussion about this acquisition. There were no non-recurring fair value adjustments during the year ended December 31, 2016.

Commitments And Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments And Contingencies

14. Commitments and Contingencies

Construction Contracts. As of December 31, 2017, we estimate the additional cost to complete the seven consolidated projects currently under construction to be approximately $282.3 million. We expect to fund this amount through a combination of one or more of the following: cash and cash equivalents, cash flows generated from operations, draws on our unsecured credit facility or other short-term borrowing, the use of debt and equity offerings under our automatic shelf registration statement, proceeds from property dispositions, equity issued from our 2017 ATM program, other unsecured borrowings or secured mortgages.

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

Other 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 December 31, 2017, we had $5.2 million in refundable earnest money deposits for potential acquisitions of operating properties and land which are included in other assets, net in our consolidated balance sheet. Of this $5.2 million in refundable earnest money deposits, $5.0 million was related to acquisitions of operating properties in St. Petersburg and Orlando, Florida which were completed in January and February 2018.

Lease Commitments. At December 31, 2017, we had long-term leases covering certain land, office facilities and equipment. Rental expense totaled approximately $4.0 million, $4.1 million, and $3.4 million for the years ended December 31, 2017, 2016 and 2015, respectively. Minimum annual rental commitments for the years ending December 31, 2018 through 2022 are approximately $2.9 million, $2.8 million, $2.8 million, $2.8 million and $2.6 million, respectively, and approximately $6.7 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.

Employment Agreements. At December 31, 2017, we had employment agreements with 13 of our senior officers, the terms of which expire at various times through August 20, 2018. Such agreements provide for minimum salary levels as well as various incentive compensation arrangements, which are payable based on the attainment of specific goals. The agreements also provide for severance payments plus a gross-up payment if certain situations occur, such as termination without cause or a change of control. In the case of 10 of the agreements, the severance payment equals one times the respective current annual base salary in the case of termination without cause and 2.99 times the respective average annual base salary over the previous three fiscal years in the case of a change of control and a termination of employment or a material adverse change in the scope of their duties. In the case of one agreement, the severance payment equals one times the respective current annual base salary for termination without cause and 2.99 times the greater of current gross income or average gross income over the previous three fiscal years in the case of a change of control. In the case of the other two agreements, the severance payment generally equals 2.99 times the respective average annual compensation over the previous three fiscal years in connection with, among other things, a termination without cause or a change of control, and the officer would be entitled to receive continuation and vesting of certain benefits in the case of such termination.

Hurricanes. In August 2017, Hurricane Harvey impacted certain multifamily communities within our Texas portfolio. In September 2017, Hurricane Irma impacted certain multifamily communities throughout the state of Florida, and in the Atlanta, Georgia and Charlotte, North Carolina areas. We incurred approximately $3.9 million of expenses at our wholly-owned multifamily communities impacted by these hurricanes which is recorded in property operating and maintenance expenses, with no insurance recoveries anticipated. We also incurred approximately $0.7 million in other storm-related expenses relating to these hurricanes, which are recorded in general and administrative expenses. Additionally, we recognized $0.4 million, representing our share of ownership interest of hurricane-related expenses incurred by the multifamily communities of the Fund which is recorded in equity in income of joint ventures.

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

12 Months Ended

Dec. 31, 2017

Accounting Policies [Abstract]

Principles Of Consolidation

Principles of Consolidation. Our consolidated financial statements include our accounts and the accounts of other subsidiaries and joint ventures (including partnerships and limited liability companies) over which we have control. All intercompany transactions, balances, and profits have been eliminated in consolidation. Investments acquired or created are evaluated based on the accounting guidance relating to variable interest entities (“VIEs”), which requires the consolidation of VIEs in which we are considered to be the primary beneficiary. If the investment is determined not to be a VIE, then the investment is evaluated for consolidation primarily using a voting interest model. In determining if we have a controlling financial interest, we consider factors such as ownership interests, authority to make decisions, kick-out rights and participating rights. At December 31, 2017, 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 continue to consolidate these operating partnerships.

Acquisitions of Real Estate

Acquisitions of Real Estate. Upon acquisition of real estate, we determine the fair value of tangible and intangible assets, which includes land, buildings (as-if-vacant), furniture and fixtures, the value of in-place leases, including above and below market leases, and acquired liabilities. In estimating these values, we apply methods similar to those used by independent appraisers of income-producing property. Upon our adoption of Accounting Standard Update 2017-01 ("ASU 2017-01") on January 1, 2017, as discussed below in Recent Accounting Pronouncements, we believe most future transaction costs relating to acquisition of operating assets will be capitalized. Prior to our adoption of ASU 2017-01 transaction costs associated with the acquisition of operating assets were expensed as incurred. Estimates of fair value of acquired debt are based upon interest rates available for the issuance of debt with similar terms and remaining maturities. Depreciation is computed on a straight-line basis over the remaining useful lives of the related tangible assets. The value of in-place leases and above or below market leases is amortized over the estimated average remaining life of leases in place at the time of acquisition. The net carrying value of below market leases is included in other liabilities in our consolidated balance sheets and the net carrying value of in-place leases is included in other assets, net in our consolidated balance sheets.

During the year ended December 31, 2017, we recognized amortization expense related to in-place leases of approximately $1.3 million. During the year ended December 31,2015, we recognized revenues related to below market leases of approximately $0.1 million and amortization expense related to in-place leases of approximately $0.5 million. We did not recognize any revenue or amortization expense related to below market or in-place leases for the year ended December 31, 2016.

The weighted average amortization period of in-place leases was approximately six months for the year ended December 31, 2017. The weighted average amortization period of below market leases and in-place leases were approximately eight months for the year ended December 31, 2015.

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 undiscounted cash flows, trends, strategic decisions regarding future development plans, and other factors in our assessment of whether impairment conditions exist. While we believe our estimates of future cash flows are reasonable, different assumptions regarding a number of factors, including market rents, economic conditions, and occupancies, could significantly affect these estimates. In estimating fair value, management uses appraisals, management estimates, and discounted cash flow calculations which 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 years ended December 31, 2017, 2016, or 2015.

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

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

Cash, Cash Equivalents, and Short-term Investments

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

Cost Capitalization

Cost Capitalization. Real estate assets are carried at cost plus capitalized carrying charges. Carrying charges are primarily interest and real estate taxes which are capitalized as part of properties under development. Capitalized interest is generally based on the weighted average interest rate of our unsecured debt. Expenditures directly related to the development and improvement of real estate assets are capitalized at cost as land and buildings and improvements. Indirect development costs, including salaries and benefits and other related costs directly attributable to the development of properties, are also capitalized. We begin capitalizing development, construction, and carrying costs when the development of the future real estate asset is probable and activities necessary to 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. As apartment homes within development properties are completed, the total capitalized development cost of each apartment home is transferred from properties under development including land to buildings and improvements.

As discussed above, carrying charges are principally interest and real estate taxes capitalized as part of properties under development. Capitalized interest was approximately $15.2 million, $18.2 million, and $19.3 million for the years ended December 31, 2017, 2016, and 2015, respectively. Capitalized real estate taxes were approximately $2.4 million, $4.5 million, and $3.6 million for the years ended December 31, 2017, 2016, and 2015, respectively.

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

We also incur expenditures related to renovation and construction of office space we lease and we capitalize these leasehold improvements as furniture, fixtures, equipment and other. We depreciate these costs using the straight-line method over the shorter of the lease term or the useful life of the improvement.

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

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

Derivative Financial Instruments

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

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 during the period 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 consolidated balance sheets. Subsequent to classification of a property as held for sale, no further depreciation is recorded. Consolidated operating properties sold or classified as held for sale, which do not meet the above criteria of discontinued operations are not included in discontinued operations and the related gains and losses are included in continuing operations. 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 accounting principles generally accepted in the United States of America ("GAAP"), provided various criteria relating to the terms of sale and any subsequent involvement with the real estate sold are satisfied.

See Note 7, "Acquisitions, Dispositions, and Discontinued Operations," for discussion of discontinued operations for the year ended December 31, 2016.

Fair Value

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

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

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

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

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

Recurring Fair Value Measurements. The following describes the valuation methodologies we use to measure different financial instruments at fair value on a recurring basis:

Deferred Compensation Plan Investments. The estimated fair values of investment securities classified as deferred compensation plan investments are based on quoted market prices utilizing public information for the same transactions. Our deferred compensation plan investments are recorded in other assets in our 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.

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

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

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 December 31, 2017 and 2016, 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 value of our notes receivable, which are included in other assets, net in our consolidated balance sheets, approximates their fair value. The estimated fair values 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.

Income Recognition

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

Reclassifications

Reclassifications. Certain reclassifications have been made to amounts in prior period financial statements to conform to the current period presentation. We reclassified certain insignificant amounts in the consolidated statements of cash flows for the years ended December 31, 2016 and 2015. These reclassifications had no impact on our consolidated cash flows from operating, investing or financing activities.

Insurance

Insurance. Our primary lines of insurance coverage are property, general liability, health, and workers’ compensation. We believe our insurance coverage adequately insures our properties against the risk of loss attributable to fire, earthquake, hurricane, tornado, flood, and other perils and adequately insures us against other risks. Losses are accrued based upon our estimates of the aggregate liability for claims incurred using certain actuarial assumptions followed in the insurance industry and based on our experience.

Other Assets, Net

Other Assets, Net. Other assets in our consolidated financial statements include investments under deferred compensation plans, deferred financing costs, non-real estate leasehold improvements and equipment, notes receivable, prepaid expenses, the value of in-place leases net of related accumulated amortization, and other miscellaneous receivables. Investments under deferred compensation plans are classified as trading securities and are adjusted to fair market value at period end. For a further discussion of our investments under deferred compensation plans, see Note 11, “Share-based Compensation and Benefit Plans.” Deferred financing costs are related to our unsecured credit facility and unsecured short-term borrowing facility, and are amortized no longer than the terms of the related facilities on the straight-line method, which approximates the effective interest method. Corporate leasehold improvements and equipment are depreciated using the straight-line method over the shorter of the expected useful lives or the lease terms which generally range from three to ten years.

Our notes receivable relate to real estate secured loans to unaffiliated third parties. At December 31, 2017 and 2016, we had one outstanding note receivable balance of approximately $18.8 million and $17.2 million, respectively. The weighted average interest rates were approximately 4.0% for each of the years ended December 31, 2017 and 2016 related to such note. At December 31, 2017, construction was complete on this project and we were not committed to fund any additional amounts under the note. Interest is recognized over the life of the note 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. All cash receipts on impaired notes are applied to reduce the principal amount of such notes until the principal has been recovered and, thereafter, are recognized as interest income. There were no impairments as of December 31, 2017 or 2016.

Reportable Segments

Reportable Segments. We operate in a single reportable segment which includes the ownership, management, development, redevelopment, acquisition, and construction of multifamily apartment communities. Each of our operating properties is considered a separate operating segment as each property earns revenues and incurs expenses, individual operating results are reviewed and discrete financial information is available. We do not distinguish or group our consolidated operations based on geography, size or type. Our multifamily apartment communities have similar long-term economic characteristics and provide similar products and services to our residents. Further, all material operations are within the United States and no multifamily apartment community comprises more than 10% of consolidated revenues. As a result, our operating properties are aggregated into a single reportable segment. Our multifamily communities generate rental revenue and other income through the leasing of apartment homes, which comprised approximately 99% of our total property revenues and total non-property income, excluding income on deferred compensation plans, for each of the years ended December 31, 2017, 2016, and 2015.

Restricted Cash

Restricted Cash. Restricted cash consists of escrow deposits held by lenders for property taxes, insurance and replacement reserves, cash required to be segregated for the repayment of residents’ security deposits, and escrowed amounts related to our development and acquisition activities. Substantially all restricted cash is invested in demand and short-term instruments.

Share-based Compensation

Share-based Compensation. Compensation expense associated with share-based awards is recognized in our consolidated statements of income and comprehensive income using the grant-date fair values. Compensation cost for all share-based awards, including options, requires measurement at estimated fair value on the grant date and recognition of compensation expense over the requisite service period for awards expected to vest. The fair value of stock option grants is estimated using the Black-Scholes valuation model. Valuation models require the input of assumptions, including judgments to estimate the expected stock price volatility, expected life, and forfeiture rate. The compensation cost for share-based awards is based on the market value of the shares on the date of grant.

In the application of GAAP, management is required to make estimates and assumptions which affect the reported amounts of assets and liabilities at the date of the financial statements, results of operations during the reporting periods, and related disclosures. Our more significant estimates include estimates supporting our impairment analysis related to the carrying values of our real estate assets. These estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances. Future events rarely develop exactly as forecasted, and the best estimates routinely require adjustment.

Recent Accounting Pronouncements

Recent Accounting Pronouncements. In January 2017, the Financial Accounting Standards Board ("FASB") issued ASU 2017-01, "Clarifying the Definition of a Business (Topic 805)." ASU 2017-01 clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. ASU 2017-01 is effective for interim and annual periods beginning after December 15, 2017, early adoption was permitted, and we adopted ASU 2017-01 as of January 1, 2017. We believe most of our future acquisitions of operating properties will qualify as asset acquisitions and most future transaction costs associated with these acquisitions will be capitalized.

In February 2017, the FASB issued ASU 2017-05, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets." ASU 2017-05 clarifies the definition of an in-substance nonfinancial asset and changes the accounting for partial sales of nonfinancial assets to be more consistent with the accounting for a sale of a business pursuant to ASU 2017-01. This update is effective for interim and annual periods beginning after December 15, 2017 using a full retrospective or modified retrospective method and is required to be adopted in conjunction with ASU 2014-09, "Revenue from Contracts with Customers" discussed below. We adopted ASU 2017-05 as of January 1, 2018, along with our adoption of ASU 2014-09, using the modified retrospective method and it did not have a material impact on our consolidated financial statements. We believe most of our future contributions of nonfinancial assets to our joint ventures, if any, will result in the recognition of a full gain or loss as if we sold 100% of the nonfinancial asset and we will also measure our retained interest at fair value.

In May 2014, the FASB issued ASU 2014-09 which prescribes a single, common revenue standard to replace most existing revenue recognition guidance in GAAP, including most industry-specific requirements. The standard outlines a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied. Several ASUs have been issued since the issuance of ASU 2014-09 which modify certain sections of the new revenue recognition standard, and are intended to promote a more consistent interpretation and application of the principles outlined in the standard. We adopted ASU 2014-09, and all related amendments, effective January 1, 2018 using the modified retrospective with cumulative-effect transition method which requires us to recognize the cumulative effect of initially applying the new revenue standard as an adjustment, if any, to the opening balance of retained earnings. We have identified our revenue streams and finalized our evaluation of the impact on our consolidated financial statements and internal accounting processes. Upon adoption, we will present certain revenue streams, which are currently included as a component of our other property revenues, as rental revenues due to the nature and timing of revenue recognition for these revenue streams. The new presentation will be applied prospectively upon adoption as this adjustment will not have an impact upon total property revenues or the opening balance of retained earnings and the adoption of ASU 2014-09 and its related amendments will not have a material impact on our consolidated financial statements as the majority of our revenue is derived from real estate lease contracts. Had ASU 2014-09 been effective as of January 1, 2017, we would have reclassified approximately $21.9 million from other property revenue to rental revenue for the year end December 31, 2017.

In February 2016, the FASB issued ASU 2016-02, "Leases." ASU 2016-02 supersedes the current accounting for leases and while retaining two distinct types of leases, finance and operating, (i) requires lessees to record a right of use asset and a related liability for the rights and obligations associated with a lease, regardless of lease classification, and recognize lease expense in a manner similar to current accounting (ii) eliminates most real estate specific lease provisions, and (iii) aligns many of the underlying lessor model principles with those in the new revenue standard. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. We are required to adopt ASU 2016-02 using the modified retrospective approach which requires us to record leases existing as of or are entered into after the beginning of the earliest comparative period presented in the financial statements under the new lease standard. We anticipate adopting ASU 2016-02 as of January 1, 2019. Based on our assessments, most of our operating lease commitments will be subject to the new guidance and recognized as operating lease liabilities and right-of-use assets upon adoption and believe our adoption of the new leasing standard will have an immaterial increase in the assets and liabilities on our consolidated balance sheets, with no material impact to our consolidated statements of income and comprehensive income. However, the ultimate impact will depend on our lease portfolio as of the adoption date.

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 we adopted ASU 2016-09 as of January 1, 2017. Upon adoption we elected to recognize forfeitures of share-based payment awards as they occur, rather than estimating forfeitures at the time awards are granted. Historically, our estimated forfeitures approximated actual forfeitures and the impact of the change in policy upon our adoption of ASU 2016-09 did not have a material impact on our consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, "Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)." ASU 2016-15 clarifies how eight 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 retrospectively. We adopted ASU 2016-15 as of January 1, 2018 using the retrospective method by applying the cumulative earnings approach to classify distributions received from our equity method investees and it did not have a material effect on our consolidated statements of cash flows upon adoption.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." ASU 2017-12 amends the hedge accounting model to provide better insight to risk management activities in the financial statements, reduces the complexity in cash flow hedges of interest rate risk, eliminates the requirement to separately measure and report hedge ineffectiveness, requires the entire change in the fair value of a hedging instrument included in the assessment of the hedge effectiveness to be recorded in other comprehensive income, with amounts reclassified to earnings to be presented in the same line item used to present the earnings effect of the hedged item when the hedged item affects earnings and allows the initial prospective quantitative assessment of hedge effectiveness to be performed at any time after hedge designation, but no later than the first quarterly effectiveness testing date. ASU 2017-12 is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The amendments in this standard must be applied using the modified retrospective approach for cash flow and net investment hedge relationships existing on the date of adoption. We adopted ASU 2017-12 in the third quarter of 2017, and this adoption had no impact upon adoption as we had no hedging activities in the prior periods presented.
