Summary of Significant Accounting Policies and Recent Accounting Pronouncements</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Principles of Consolidation</font><font style="font-family:inherit;font-size:10pt;">. Our consolidated financial statements include our accounts and the accounts of other subsidiaries and joint ventures (including partnerships and limited liability companies) over which we have control. All intercompany transactions, balances, and profits have been eliminated in consolidation. Investments acquired or created are evaluated based on the accounting guidance relating to variable interest entities (“VIEs”), which requires the consolidation of VIEs in which we are considered to be the primary beneficiary. If the investment is determined not to be a VIE, then the investment is evaluated for consolidation (primarily using a voting interest model) under the remaining consolidation guidance relating to real estate entities. If we are the general partner of a limited partnership, or manager of a limited liability company, we also consider the consolidation guidance relating to the rights of limited partners, or non-managing members, as the case may be, to assess whether any rights held by the limited partners, or non-managing members, as the case may be, overcome the presumption of control by us.</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Acquisitions of Real Estate</font><font style="font-family:inherit;font-size:10pt;">. Upon acquisition of real estate, we determine the fair value of tangible and intangible assets, which includes land, buildings (as-if-vacant), furniture and fixtures, the value of in-place leases, including above and below market leases, and acquired liabilities. In estimating these values, we apply methods similar to those used by independent appraisers of income-producing property. Upon the acquisition of a controlling interest of an investment in an unconsolidated joint venture, such joint venture is consolidated and our initial equity investment is remeasured to fair value at the date the controlling interest is acquired; any difference between the carrying value of the previously held equity investment and the fair value is recognized in earnings at the time of obtaining control. Transaction costs associated with the acquisition of operating real estate assets are expensed. Estimates of fair value of acquired debt are based upon interest rates available for the issuance of debt with similar terms and remaining maturities. Depreciation is computed on a straight-line basis over the remaining useful lives of the related tangible assets. The value of in-place leases and above or below market leases is amortized over the estimated average remaining life of leases in place at the time of acquisition. The net carrying value of below market leases is included in other liabilities in our consolidated balance sheets and the net carrying value of in-place leases is included in other assets, net in our consolidated balance sheets. </font></div><div style="line-height:120%;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The carrying values of below

style="font-family:inherit;font-size:10pt;">. Long-lived assets are reviewed for impairment annually or whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Impairment may exist if estimated future undiscounted cash flows associated with long-lived assets are not sufficient to recover the carrying value of such assets. We consider projected future discounted and undiscounted cash flows, trends, strategic decisions regarding future development plans, and other factors in our assessment of whether impairment conditions exist. While we believe our estimates of future cash flows are reasonable, different assumptions regarding a number of factors, including market rents, economic conditions, and occupancies, could significantly affect these estimates. In estimating fair value, management uses appraisals, management estimates, and discounted cash flow calculations which 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 </font><font style="font-family:inherit;font-size:10pt;">December 31, 2015</font><font style="font-family:inherit;font-size:10pt;"> or </font><font style="font-family:inherit;font-size:10pt;">2013</font><font style="font-family:inherit;font-size:10pt;">.

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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Cash and Cash Equivalents</font><font style="font-family:inherit;font-size:10pt;">. 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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Cost Capitalization</font><font style="font-family:inherit;font-size:10pt;">. 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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">As discussed above, carrying charges are principally interest and real estate taxes capitalized as part of properties under development. Capitalized interest was approximately </font><font style="font-family:inherit;font-size:10pt;">$19.3 million</font><font style="font-family:inherit;font-size:10pt;">, </font><font style="font-family:inherit;font-size:10pt;">$22.2 million</font><font style="font-family:inherit;font-size:10pt;">, and </font><font style="font-family:inherit;font-size:10pt;">$15.7 million</font><font style="font-family:inherit;font-size:10pt;"> for the years ended </font><font style="font-family:inherit;font-size:10pt;">December 31, 2015</font><font style="font-family:inherit;font-size:10pt;">, </font><font style="font-family:inherit;font-size:10pt;">2014</font><font style="font-family:inherit;font-size:10pt;">, and </font><font style="font-family:inherit;font-size:10pt;">2013</font><font style="font-family:inherit;font-size:10pt;">, respectively. Capitalized real estate taxes were approximately </font><font style="font-family:inherit;font-size:10pt;">$3.6 million</font><font style="font-family:inherit;font-size:10pt;">, </font><font style="font-family:inherit;font-size:10pt;">$4.4 million</font><font style="font-family:inherit;font-size:10pt;">, and </font><font style="font-family:inherit;font-size:10pt;">$3.0 million</font><font style="font-family:inherit;font-size:10pt;"> for the years ended </font><font style="font-family:inherit;font-size:10pt;">December 31, 2015</font><font style="font-family:inherit;font-size:10pt;">, </font><font style="font-family:inherit;font-size:10pt;">2014</font><font style="font-family:inherit;font-size:10pt;">, and </font><font style="font-family:inherit;font-size:10pt;">2013</font><font style="font-family:inherit;font-size:10pt;">, respectively.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We also incur expenditures related to renovation and construction of office space we lease and we capitalize these leasehold improvements as furniture, fixtures, equipment and other. We depreciate these costs using the straight-line method over the shorter of the lease term or the useful life of the improvement. During the third quarter of 2013, we relocated our corporate headquarters. In conjunction with this relocation, we capitalized approximately </font><font style="font-family:inherit;font-size:10pt;">$12.2 million</font><font style="font-family:inherit;font-size:10pt;"> related to leasehold improvements which is depreciated over the life of our new lease.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Depreciation and amortization is computed over the expected useful lives of depreciable property on a straight-line basis with lives generally as follows:</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:8pt;"> </font><div style="padding-left:0px;text-indent:0px;line-height:normal;padding-top:10px;"><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;font-size:10pt;width:100%;border-collapse:collapse;text-align:left;"><tr><td colspan="2" rowspan="1"></td></tr><tr><td width="80%" rowspan="1" colspan="1"></td><td width="20%" rowspan="1" colspan="1"></td></tr><tr><td style="vertical-align:bottom;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:left;font-size:8pt;"><font style="font-family:inherit;font-size:8pt;"> </font></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:center;font-size:8pt;"><font style="font-family:inherit;font-size:8pt;font-weight:bold;">Estimated</font></div><div style="text-align:center;font-size:8pt;"><font style="font-family:inherit;font-size:8pt;font-weight:bold;">Useful  Life</font></div></td></tr><tr><td style="vertical-align:top;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Buildings and improvements</font></div></td><td style="vertical-align:bottom;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">5-35 years</font></div></td></tr><tr><td style="vertical-align:top;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Furniture, fixtures, equipment and other</font></div></td><td style="vertical-align:bottom;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">3-20 years</font></div></td></tr><tr><td style="vertical-align:top;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Intangible assets/liabilities (in-place leases and below market leases)</font></div></td><td style="vertical-align:bottom;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">underlying lease term</font></div></td></tr></table></div><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Discontinued Operations</font><font style="font-family:inherit;font-size:10pt;">. We adopted ASU 2014-08, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">"Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,"</font><font style="font-family:inherit;font-size:10pt;"> on January 1, 2014, which required only disposals representing a strategic shift, such as a major line of business, a major geographical area or a major equity investment, to be classified as a discontinued operation. We generally believe future sales of our individual operating properties will no longer qualify as discontinued operations effective with our adoption of this new standard. Prior to January 1, 2014 a property was classified as a discontinued operation when (i) the operations and cash flows of the property could be clearly distinguished and had been or would be eliminated from our ongoing operations; (ii) the property either had been disposed of or was classified as held for sale; and (iii) we would not have any significant continuing involvement in the operations of the property after the disposal transaction. </font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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. 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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"> There were no disposals reported as discontinued operations for the years ended December 31, 2015 or 2014.

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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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:</font></div><div style="line-height:120%;text-align:left;font-size:8pt;"><font style="font-family:inherit;font-size:8pt;"> </font></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:60px;" rowspan="1" colspan="1"></td><td rowspan="1" colspan="1"></td></tr><tr><td style="vertical-align:top" rowspan="1" colspan="1"><div style="line-height:120%;font-size:10pt;padding-left:36px;"><font style="font-family:inherit;font-size:10pt;">•</font></div></td><td style="vertical-align:top;" rowspan="1" colspan="1"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Level 1: Quoted prices for identical instruments in active markets.</font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-top:8px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:60px;" rowspan="1" colspan="1"></td><td rowspan="1" colspan="1"></td></tr><tr><td style="vertical-align:top" rowspan="1" colspan="1"><div style="line-height:120%;font-size:10pt;padding-left:36px;"><font style="font-family:inherit;font-size:10pt;">•</font></div></td><td style="vertical-align:top;" rowspan="1" colspan="1"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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.</font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-top:8px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:60px;" rowspan="1" colspan="1"></td><td rowspan="1" colspan="1"></td></tr><tr><td style="vertical-align:top" rowspan="1" colspan="1"><div style="line-height:120%;font-size:10pt;padding-left:36px;"><font style="font-family:inherit;font-size:10pt;">•</font></div></td><td style="vertical-align:top;" rowspan="1" colspan="1"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Level 3: Significant inputs to the valuation model are unobservable.</font></div></td></tr></table><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Recurring Fair Value Measurements.</font><font style="font-family:inherit;font-size:10pt;"> The valuation methodology we use to measure our deferred compensation plan investments is based on quoted market prices utilizing public information for the same transactions. Our deferred compensation plan investments are recorded at fair value on a recurring basis and included in other assets in our consolidated balance sheets.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Non-recurring Fair Value Measurements.</font><font style="font-family:inherit;font-size:10pt;"> 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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Financial Instrument Fair Value Disclosures.</font><font style="font-family:inherit;font-size:10pt;"> As of </font><font style="font-family:inherit;font-size:10pt;">December 31, 2015</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">2014</font><font style="font-family:inherit;font-size:10pt;">, the carrying values of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and distributions payable represent fair value because of the short-term nature of these instruments. The carrying value of restricted cash approximates its fair value based on the nature of our assessment of the ability to recover these amounts. 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. </font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Income Recognition</font><font style="font-family:inherit;font-size:10pt;">. Our rental and other property revenue is recorded when due from residents and is recognized monthly as it is earned. Other property revenue consists primarily of utility rebillings and administrative, application, and other transactional fees charged to our residents. Our apartment homes are rented to residents on lease terms generally ranging from six to fifteen months, with monthly payments due in advance. All other sources of income, including interest and fee and asset management income, are recognized as earned. Operations of multifamily properties acquired are recorded from the date of acquisition in accordance with the acquisition method of accounting. In management’s opinion, due to the number of residents, the types and diversity of submarkets in which our properties operate, and the collection terms, there is no significant concentration of credit risk.</font></div><div style="line-height:120%;padding-top:10px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Reclassifications. </font><font style="font-family:inherit;font-size:10pt;">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, 2014 and 2013. These reclassifications had no impact on our consolidated cash flows from operating, investing or financing activities. In addition, we also reclassified deferred financing charges relating to our unsecured credit facility and unsecured short-term borrowing facility to depreciation and amortization. All other deferred charges were reclassified to interest expense effective with our adoption of Accounting Standards Update 2015-03 ("ASU 2015-03"), </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">"Simplifying the Presentation of Debt Issuance Costs,"</font><font style="font-family:inherit;font-size:10pt;"> as discussed below in Recent Accounting Pronouncements.</font></div><div style="line-height:120%;padding-top:10px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Insurance</font><font style="font-family:inherit;font-size:10pt;">. 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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Other Assets, Net</font><font style="font-family:inherit;font-size:10pt;">. 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 10, “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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our notes receivable relate to real estate secured loans to unaffiliated third parties. At December 31, 2015 and 2014, we had outstanding notes receivable balances of approximately </font><font style="font-family:inherit;font-size:10pt;">$13.2 million</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">$3.4 million</font><font style="font-family:inherit;font-size:10pt;">, respectively, and the weighted average interest rate on such notes was approximately </font><font style="font-family:inherit;font-size:10pt;">4.1%</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">4.3%</font><font style="font-family:inherit;font-size:10pt;"> for the years ended December 31, 2015 and 2014, respectively. At December 31, 2015, we were also committed to funding additional amounts under one of the loans in the amount of approximately </font><font style="font-family:inherit;font-size:10pt;">$8.3 million</font><font style="font-family:inherit;font-size:10pt;">. Interest is recognized over the lives of the notes and is included in interest and other income in our consolidated statements of income and comprehensive income. We consider a note receivable to be impaired if it is probable we will not collect all contractually due principal and interest. We do not accrue interest when a note is considered impaired and an allowance is recorded for any principal and previously accrued interest which is not believed to be collectible. 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, 2015 or 2014.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Reportable Segments</font><font style="font-family:inherit;font-size:10pt;">. 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 </font><font style="font-family:inherit;font-size:10pt;">99%</font><font style="font-family:inherit;font-size:10pt;"> of our total property revenues and total non-property income, excluding income on deferred compensation plans, for each of the years ended </font><font style="font-family:inherit;font-size:10pt;">December 31, 2015</font><font style="font-family:inherit;font-size:10pt;"> and 2014, and </font><font style="font-family:inherit;font-size:10pt;">98%</font><font style="font-family:inherit;font-size:10pt;"> for the year ended </font><font style="font-family:inherit;font-size:10pt;">December 31, 2013</font><font style="font-family:inherit;font-size:10pt;">.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Restricted Cash</font><font style="font-family:inherit;font-size:10pt;">. 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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Share-based Compensation</font><font style="font-family:inherit;font-size:10pt;">. 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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Use of Estimates</font><font style="font-family:inherit;font-size:10pt;">. 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.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Recent Accounting Pronouncements. </font><font style="font-family:inherit;font-size:10pt;">In February 2015, the FASB issued Accounting Standards Update 2015-02 ("ASU 2015-02"), </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">"Amendments to the Consolidation Analysis."</font><font style="font-family:inherit;font-size:10pt;"> ASU 2015-02 changes the analysis a reporting entity must perform to determine whether it should consolidate certain types of legal entities. ASU 2015-02 modifies whether limited partnerships and similar entities are VIEs or voting interest entities and eliminates the presumption a general partner should consolidate a limited partnership. Reporting entities which consolidate or hold a variable interest in a VIE as a result of this standard are subject to additional disclosure requirements. ASU 2015-02 is effective for us on January 1, 2016 and did not have a material impact on our consolidated financial statements. However, upon adoption, two of our consolidated operating partnerships, as discussed in Note 5, "Operating Partnerships," would now qualify as VIEs. As we would be considered the primary beneficiary, we would continue to consolidate these operating partnerships.</font></div><div style="line-height:120%;padding-top:10px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In April 2015, the FASB issued ASU 2015-03, which requires all costs incurred to issue debt to be presented in the balance sheet as a direct deduction from the carrying value of the debt rather than being recorded as a deferred charge and presented as an asset. ASU 2015-03 also requires amortization of debt issuance costs to be reported as interest expense in the statement of income. In August 2015, the FASB issued Accounting Standards Update 2015-15 ("ASU 2015-15"), </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">"Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements."</font><font style="font-family:inherit;font-size:10pt;"> ASU 2015-15 supplements the requirements of ASU 2015-03 by allowing an entity to defer and present debt issuance costs related to a line of credit arrangement as an asset and subsequently amortize the deferred costs ratably over the term of the line of credit arrangement. We adopted ASU 2015-03 effective December 31, 2015. Prior to adoption, we reported amortization expense of debt issuance costs as a separate line item in our consolidated statements of income. Upon our adoption of ASU 2015-03, debt issuance costs related to our unsecured credit facility and unsecured short-term borrowing facility continue to be presented within other assets, net on our consolidated balance sheets. However, the retrospective application required upon adoption of this ASU resulted in a reclassification of approximately </font><font style="font-family:inherit;font-size:10pt;">$10.9 million</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">$12.9 million</font><font style="font-family:inherit;font-size:10pt;"> of debt issuance costs from other assets, net to a deduction from unsecured and secured notes payable in our consolidated balance sheets as of December 31, 2015 and 2014, respectively. The retrospective application upon adoption also resulted in a reclassification of approximately </font><font style="font-family:inherit;font-size:10pt;">$1.7 million</font><font style="font-family:inherit;font-size:10pt;">, </font><font style="font-family:inherit;font-size:10pt;">$1.6 million</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">$1.7 million</font><font style="font-family:inherit;font-size:10pt;"> from amortization of deferred financing costs to a component of interest expense in our consolidated statements of income and comprehensive income for the years ended December 31, 2015, 2014, and 2013, respectively.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In January 2016, the FASB issued Accounting Standards Update 2016-01 ("ASU 2016-01"), </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">"Recognition and Measurement of Financial Assets and Financial Liabilities."</font><font style="font-family:inherit;font-size:10pt;"> ASU 2016-01 changes certain recognition, measurement, presentation, and disclosure requirements for financial instruments. This standard requires all equity investments, except those accounted for under the equity method of accounting or resulting in consolidation, to be measured at fair value with changes in fair value recognized in net income. This standard also simplifies the impairment assessment for equity investments without readily determinable fair values, amends the presentation requirements for changes in the fair value of financial liabilities, requires presentation of financial instruments by measurement category and form of financial asset, and eliminates the requirement to disclose the methods and significant assumptions used in estimating the fair value of financial instruments. ASU 2016-01 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is not permitted except for the amended presentation requirements for changes in the fair value of financial liabilities. We expect to adopt ASU 2016-01 as of January 1, 2018, and do not expect it to have a material impact on our consolidated financial statements upon adoption.</font></div><div style="line-height:120%;padding-top:10px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;"> </font><font style="font-family:inherit;font-size:10pt;">In May 2014, the FASB issued Accounting Standards Update 2014-09 ("ASU 2014-09"), </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">"Revenue from Contracts with Customers." </font><font style="font-family:inherit;font-size:10pt;">ASU 2014-09 provides a single comprehensive revenue recognition model for contracts with customers (excluding certain contracts, such as lease contracts) to improve comparability within industries. ASU 2014-09 requires an entity to recognize revenue to reflect the transfer of goods or services to customers at an amount the entity expects to be paid in exchange for those goods and services and provide enhanced disclosures, all to provide more comprehensive guidance for transactions such as service revenue and contract modifications. In August 2015, the FASB deferred the effective date of ASU 2014-09 by one year, and it is now effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted but not before the original effective date. ASU 2014-09 may be applied using either a full retrospective or a modified approach upon adoption. We expect to adopt this standard as of January 1, 2018 and we are currently evaluating the impact this standard may have on our consolidated financial statements.</font></div></div>
