2. Summary of Significant Accounting Policies and Recent Accounting Pronouncements

Principles of Consolidation. Our condensed consolidated financial statements include our accounts and the accounts of other subsidiaries and joint ventures (including partnerships and limited liability companies) over which we have control. All intercompany transactions, balances, and profits have been eliminated in consolidation. Investments acquired or created are evaluated based on the accounting guidance relating to variable interest entities ("VIEs"), which requires the consolidation of VIEs in which we are considered to be the primary beneficiary. If the investment is determined not to be a VIE, then the investment is evaluated for consolidation (primarily using a voting interest model) under the remaining consolidation guidance relating to real estate entities. If we are the general partner of a limited partnership, or manager of a limited liability company, we also consider the consolidation guidance relating to the rights of limited partners, or non-managing members, to assess whether the limited partners, or non-managing members, hold substantive kick-out or participating rights which indicate we do not have a controlling financial interest. At March 31, 2016, two of our consolidated operating partnerships are VIEs, of which we held between 92% and 94% of the outstanding common limited partnership units and the sole 1% general partnership interest of each consolidated operating partnership. As we are considered the primary beneficiary, we would continue to consolidate these operating partnerships.

Interim Financial Reporting. We have prepared these unaudited financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial statements and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, these statements do not include all information and footnote disclosures required for annual statements. While we believe the disclosures presented are adequate for interim reporting, these interim unaudited financial statements should be read in conjunction with the audited financial statements and notes included in our 2015 Annual Report on Form 10-K. Certain insignificant amounts in the unaudited condensed consolidated statements of cash flows for the three months ended March 31, 2015 have been reclassified to conform to the current year presentation. These reclassifications had no impact on our condensed consolidated cash flows from

operating, investing or financing activities. As a result of our adoption of Accounting Standards Update 2015-03 ("ASU 2015-03"), "Simplifying the Presentation of Debt Issuance Costs," as supplemented by Accounting Standards Update 2015-15 ("ASU 2015-15"), "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements," as of December 31, 2015, we reclassified $0.4 million of deferred financing charges relating to our unsecured credit facility to depreciation and amortization in our condensed consolidated statements of income and comprehensive income for the three months ended March 31, 2015. We also reclassified $0.4 million of deferred charges for the three months ended March 31, 2015 to interest expense. In the opinion of management, all adjustments and eliminations, consisting of normal recurring adjustments, necessary for a fair representation of our financial statements for the interim period reported have been included. Operating results for the three months ended March 31, 2016 are not necessarily indicative of the results which may be expected for the full year.

Acquisitions of Real Estate. Upon acquisition of real estate, we determine the fair value of tangible and intangible assets, which includes land, buildings (as-if-vacant), furniture and fixtures, the value of in-place leases, including above and below market leases, and acquired liabilities. In estimating these values, we apply methods similar to those used by independent appraisers of income-producing property. Upon the acquisition of a controlling interest of an investment in an unconsolidated joint venture, such joint venture is consolidated and our initial equity investment is remeasured to fair value at the date the controlling interest is acquired; any 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.

Asset Impairment. Long-lived assets are reviewed for impairment annually or whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Impairment may exist if estimated future undiscounted cash flows associated with long-lived assets are not sufficient to recover the carrying value of such assets. We consider projected future discounted and undiscounted cash flows, trends, strategic decisions regarding future development plans, and other factors in our assessment of whether impairment conditions exist. While we believe our estimates of future cash flows are reasonable, different assumptions regarding a number of factors, including, but not limited to, market rents, economic conditions, and occupancies, could significantly affect these estimates. In estimating fair value, management uses appraisals, management estimates, and discounted cash flow calculations which utilize inputs from a marketplace participant's perspective. When impairment exists, the long-lived asset is adjusted to its fair value. In addition, we evaluate our equity investments in joint ventures and if we believe there is an other than temporary decline in market value of our investment below our carrying value, we will record an impairment charge. We did not record any impairment charges for the three months ended March 31, 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.

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.

As discussed above, carrying charges are principally interest and real estate taxes capitalized as part of properties under development. Capitalized interest was approximately $4.6 million and $5.4 million for the three months ended March 31, 2016 and 2015, respectively. Capitalized real estate taxes were approximately $1.6 million and $0.9 million for the three months ended March 31, 2016 and 2015, respectively.

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



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

Discontinued Operations. A property is classified as a discontinued operation when the disposal represents a strategic shift, such as disposal of a major line of business, a major geographical area or a major equity investment. The results of operations for properties sold or classified as held for sale at the end of the period, and meeting the above criteria of discontinued operations, are classified as discontinued operations for all periods presented. The property-specific components of earnings classified as discontinued operations include separately identifiable property-specific revenues, expenses, depreciation, and interest expense, if any. The gain or loss resulting from the eventual disposal of the held for sale properties meeting the criteria of discontinued operations is also classified within discontinued operations. Real estate assets held for sale are measured at the lower of carrying amount or fair value less costs to sell and are presented separately in the accompanying condensed consolidated balance sheets for all periods presented. Subsequent to classification of a property as held for sale, no further depreciation is recorded. Properties sold by our unconsolidated entities which do not meet the above criteria of discontinued operations are not included in discontinued operations and related gains or losses are reported as a component of equity in income of joint ventures.

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

See Note 5, "Acquisitions, Dispositions, Discontinued Operations and Assets Held for Sale," for a discussion of discontinued operations for the three months ended March 31, 2016. There were no discontinued operations for the three months ended March 31, 2015.

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

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


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


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


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

Recurring Fair Value Measurements. The valuation methodology we use to measure our deferred compensation plan investments is based on quoted market prices utilizing public information for the same transactions. Our deferred compensation plan investments are recorded at fair value on a recurring basis and included in other assets in our condensed consolidated balance sheets.

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 March 31, 2016 and December 31, 2015, 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 values of our notes receivable also approximate their fair values, which are based on certain factors, such as market interest rates, terms of the note and credit worthiness of the borrower. These financial instruments utilize Level 3 inputs. In calculating the fair value of our notes payable, interest rate and spread assumptions reflect current credit worthiness and market conditions available for the issuance of notes payable with similar terms and remaining maturities. These financial instruments utilize Level 2 inputs.

Notes Receivable. Our notes receivable, which are included in other assets, net, in our condensed consolidated balance sheets, relate to real estate secured loans to unaffiliated third parties. At March 31, 2016 and December 31, 2015, we had outstanding notes receivable balances of approximately $17.0 million and $13.2 million, respectively, and the weighted average interest rate on such notes was approximately 4.1% and 4.3% for the three months ended March 31, 2016 and 2015, respectively. At March 31, 2016, we were also committed to funding additional amounts under one of the loans in the amount of approximately $4.6 million. Interest is recognized over the lives of the notes and is included in interest and other income in our consolidated statements of income and comprehensive income. We consider a note receivable to be impaired if it is probable we will not collect all contractually due principal and interest. We do not accrue interest when a note is considered impaired and an allowance is recorded for any principal and previously accrued interest which is not believed to be collectible.

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

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

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

In March 2016, the FASB issued Accounting Standards Update 2016-09 ("ASU 2016-09"), "Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 amends several aspects of the accounting for share-based payment transactions, including the income tax consequences, accrual of compensation cost, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016, and early adoption is permitted. The amendments in this standard must be applied prospectively, retrospectively, or as of the beginning of the earliest comparative period presented in the year of adoption, depending on the type of amendment. We expect to adopt ASU 2016-09 as of January 1, 2017, and we are currently evaluating the impact this standard may have on our consolidated financial statements upon adoption.

In May 2014, the FASB issued Accounting Standards Update 2014-09 ("ASU 2014-09"), "Revenue from Contracts with Customers." 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. In March 2016, the FASB issued Accounting Standards Update 2016-08 ("ASU 2016-08"), "Principal versus Agent Considerations (Reporting Revenue Gross versus Net)." ASU 2016-08 amends ASU 2014-09 to assist in the decision of whether an entity is a principal or agent in a revenue transaction in which a third party is involved in providing goods or services to a customer of the entity. Early adoption of ASU 2014-09 is permitted but not before the original effective date, which applied to interim and annual periods beginning after December 15, 2016. ASU 2014-09 may be applied using either a full retrospective or a modified approach upon adoption. We expect to adopt this standard as of January 1, 2018, and we are currently evaluating the impact this standard may have on our consolidated financial statements upon adoption.
