Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted average number of shares outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per share (“EPS”("EPS"). Both the unvested restricted shares and other potentially dilutive common shares, and the related impact to earnings, are considered when calculating earnings per share on a diluted basis. The Company’sCompany's earnings per common share are determined as follows (dollars in thousands, except per share data):

All options to purchase shares of common stock outstanding as of June 30,March 31, 2017 and 2016 and 2015 are included in the computation of diluted earnings per share.

TheAs discussed under "Recently Issued and Adopted Accounting Standards," as of January 1, 2017, the Company isadopted the provision of ASU 2016-09 using the modified retrospective approach to recognize forfeitures as they occur. Prior to the adoption of this standard, the Company was required to estimate the forfeiture of stock options and recognizerecognized compensation cost net of the estimated forfeitures. The estimated forfeitures included in compensation cost arewere adjusted to reflect actual forfeitures at the end of the vesting period. The forfeiture rate at June 30, 2016 was 0.8% and is basedchange in accounting principle had an immaterial effect on the average forfeiture activity over a period equalCompany's financial position and no adjustment to retained earnings or the estimated life ofCompany's diluted shares outstanding, as prescribed under the stock options. The application of estimated forfeitures did not materially impact compensation expense formodified retrospective approach, was required in the three and six months ended June 30, 2016 or 2015.prior year period.

The Company enters into interest rate swap and interest rate cap agreements (collectively, “Hedging Derivatives”"Hedging Derivatives") for interest rate risk management purposes and in conjunction with certain variable rate secured debt to satisfy lender requirements. The Company does not enter into Hedging Derivative transactions for trading or other speculative purposes. The Company assesses the effectiveness of qualifying cash flow and fair value hedges, both at inception and on an on-going basis. Hedge ineffectiveness is reported as a component of general and administrative expenses. The fair values of Hedging Derivatives that are in an asset position are recorded in prepaid expenses and other assets. The fair value of Hedging Derivatives that are in a liability position are included in accrued expenses and other liabilities. The Company does not present or disclose the fair value of Hedging Derivatives on a net basis. Fair value changes for derivatives that are not in qualifying hedge relationships are reported as a component of interest expense, net.  For the Hedging Derivative positions that the Company has determined qualify as effective cash flow hedges, the Company has recorded the effective portion of cumulative changes in the fair value of Hedging Derivatives in other comprehensive income (loss).  Amounts recorded in other comprehensive income (loss) will be reclassified into earnings in the periods in which earnings are affected by the hedged cash flow. The effective portion of the change in fair value of the Hedging Derivatives that the Company has determined qualified as effective fair value hedges is reported as an adjustment to the carrying amount of the corresponding debt being hedged. See Note 10, "Fair Value," for further discussion of derivative financial instruments.

In January 2015, a fire occurred at the Company's Avalon at Edgewater apartment community located in Edgewater, New Jersey.Jersey ("Edgewater"). Edgewater consisted of two residential buildings. One building, containing 240 apartment homes, was destroyed. The second building, containing 168 apartment homes, suffered minimal damage and has been repaired.

The Company is aware that third parties incurred significant property damage and are claiming other losses, such as relocation costs, as a result of the fire. The Company has established protocols for processing claims from third parties who suffered losses as a result of the fire, and has encouraged any party who sustained a loss to contactmany third parties have contacted the Company's insurance carrier to file a claim.and settled their claims. See Part II, Item 1, "Legal Proceedings," for further discussion of the lawsuits associated with the Edgewater casualty loss.

Three class action lawsuits have been filed against the Company on behalf of occupants of the destroyed building and consolidated in the United States District Court for the District of New Jersey. The Company has agreed with class counsel to the terms of a proposed settlement which would provide a claims process (with agreed upon protocols for instructing the adjuster as to how to evaluate claims) and, if needed, an arbitration process to determine damage amounts to be paid to individual claimants covered by the class settlement. On July 8, 2016, class counsel filed withIn March 2017 the court a motion forDistrict Court granted preliminary approval of thisthe class action settlement and in July 2017 a fairness hearing will be held to determine whether the Company did not oppose such motion. However, the Company cannot predict when or if the courtsettlement will approve the settlement.receive final approval. A fourth class action, being heard in the same federal court, was filed against the Company on behalf of residents of the second Edgewater building that suffered minimal damage. Recently, a fifth class action lawsuit was filed against the Company seeking to certify a class on behalf of both buildings and other third parties. That action is currently stayed pending the decision by those plaintiffs either to be included in the class settlement or to formally opt-out. In addition to the class action lawsuits described above, 2019 lawsuits representing approximately 141146 individual plaintiffs have been filed and are currently pending in the Superior Court of New Jersey Bergen County - Law Division and 19 of these lawsuits are currently pending. MostDivision. All of these state court cases have been consolidated by the court and the Company expects all of themcourt. These plaintiffs, if eligible to be consolidated shortly.class members under the class settlement that has been preliminarily approved as described above, must formally opt-out of that class action settlement by May 17, 2017 if they want to continue their individual actions. The Company believes that it has meritorious defenses to the extent of damages claimed in all of the suits. There are also five subrogation lawsuits that have been filed against the Company by insurers of Edgewater residents who obtained renters insurance; it is the Company's position that in the majority of the applicable leases the residents waived subrogation rights. One of these lawsuits has been dismissed on that basis and the other four are currently pending in the United States District Court for the District of New Jersey. The District Court recently denied the Company's motions seeking dismissal on this basis. The Company will reassess the viability of this defense after conducting additional discovery.

Having incurred applicable deductibles,settled many third party claims through the insurance claims process, the Company currently believes that all of itsany potential remaining liability to third parties (including any potential liability to third parties determined in accordance with the class settlement described above, if approved) will not be material to the Company and will in any event be substantially covered by itsthe Company's insurance policies. However, the Company can give no assurances in this regard and continues to evaluate this matter. See Note 5, "Investments in Real Estate Entities," and Part II, Item 1, "Legal Proceedings," for further discussion of the casualty gains and losses and lawsuits associated with the Edgewater casualty loss.

The Company is involved in various other claims and/or administrative proceedings unrelated to the Edgewater casualty loss that arise in the ordinary course of its business. While no assurances can be given, the Company does not currently believe that any of these other outstanding litigation matters, individually or in the aggregate, will have a material adverse effect on its financial condition or results of operations.

The Company accounts for acquisitions of investments in real estate in accordance with the authoritative guidance for the initial measurement, which requires the identifiable assets acquired, the liabilities assumed and any noncontrolling interest in the acquiree to be recognized at fair value. Typical assets and liabilities acquired include land, building, furniture, fixtures and equipment, debt and identified intangible assets and liabilities, consisting of the value of above or below market leases and in-place leases. In making estimates of fair values for purposes of allocating purchase price, the Company utilizes various sources, including its own analysis of recently acquired and existing comparable properties in its portfolio and other market data. Consideration for acquisitions is typically in the form of cash unless otherwise disclosed. For an acquisition of a business, the allocation of the purchase price is based on the fair value of the net assets, and for an asset acquisition, the allocation of the purchase price is based on the relative fair value of the net assets. Subsequent to the adoption of ASU 2017-01 on October 1, 2016, the Company expects that acquisitions of individual operating communities will generally be viewed as asset acquisitions.

The preparation of 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 and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods.  Actual results could differ from those estimates.

Certain reclassifications have been made to amounts in prior years’years' notes to financial statements to conform to current year presentations as a result of changes in held for sale classification and disposition activity.

In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of share-based payment transactions, including income tax consequences, classification of awards as equity or liability, statement of cash flows classification and policy election options for forfeitures. Upon adoption of the standard, the Company elected to account for forfeitures when they occur instead of estimating the forfeitures. The Company adopted this guidance as of January 1, 2017, using the modified retrospective approach. The new standard requires eitherdid not have a prospective, retrospective or modified retrospective approach dependingmaterial effect on the amendment type.Company's financial position, results of operations or earnings per share as discussed in "Earnings per Common Share."

In February 2016, the FASB issued ASU 2016-02, Leases, amending the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. The guidance will be effective in the first quarter of 20172019 and allows for early adoption. The Company is assessing whether the new standard willrequires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief.

ASU 2016-02 provides for transition relief, which includes not electing to (i) reassess whether any expired or existing contract is a lease or contains a lease, (ii) reassess the lease classification of any expired or existing leases and (iii) expense any capitalized initial direct costs for any existing leases. The Company anticipates adoption of the standard to have a material effectimpact on its financial position orand results of operations.operations resulting from the recognition of the right to use asset and corresponding lease obligation for its long-term ground leases, currently accounted for as operating leases. The Company will continue to assess the impact of the new standard.

In connection with the Credit Facility Increase, the applicable margin over reference rates used to determine the applicable interest rates on the Company's borrowings from time to time decreased. The Credit Facility bears interest at varying levels based on the London Interbank Offered Rate ("LIBOR"), rating levels achieved on the Company's unsecured notes and on a maturity schedule selected by the Company. The current stated pricing is LIBOR plus 0.825% per annum (1.29%(1.81% at June 30, 2016)March 31, 2017), assuming a one month borrowing rate. The stated spread over LIBOR can vary from LIBOR plus 0.80% to LIBOR plus 1.55% based on the Company's credit ratings. In addition, a competitive bid option is available for borrowings up to 65% of the Credit Facility amount, which allows banks that are part of the lender consortium to bid to make loans at a rate that is lower than the stated rate if market conditions allow. In connection with the Credit Facility Increase, the annual facility fee was also amended to lower the fee tois 0.125% from 0.15%, resulting in a fee of(or approximately $1,875,000 annually based on the $1,500,000,000 facility size and based on the Company's current credit rating.rating).

Abandoned pursuit costs can vary greatly, and the costs incurred in any given period may be significantly different in future periods.

The Company evaluates its real estate and other long-lived assets for impairment when potential indicators of impairment exist. Such assets are stated at cost, less accumulated depreciation and amortization, unless the carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of a property or long-lived asset may not be recoverable, the Company assesses its recoverability by comparing the carrying amount of the property or long-lived asset to its estimated undiscounted future cash flows. If the carrying amount exceeds the aggregate undiscounted future cash flows, the Company recognizes an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property or long-lived asset. Based on periodic tests of recoverability of long-lived assets for the three and six months ended June 30,March 31, 2017 and 2016, and 2015, the Company did not recognize any impairment losses for wholly-owned operating real estate assets.

The Company assesses its portfolio of land held for both development and investment for impairment if the intent of the Company changes with respect to either the development of, or the expected holding period for, the land.

These charges related to one and three ancillary land parcels, respectively. This charge waswere determined as the excess of the Company's carrying basis over the expected sales price for each parcel, and isthese charges are included in casualty and impairment loss (gain) loss,, net on the accompanying Condensed Consolidated Statements of Comprehensive Income. The Company did not recognize any material impairment charges on its investment in land during the three and six months ended June 30, 2015.

The Company evaluates its unconsolidated investments for other than temporary impairment, considering both the extent and amount by which the carrying value of the investment exceeds the fair value, and the Company’sCompany's intent and ability to hold the investment to recover its carrying value. The Company also evaluates its proportionate share of any impairment of assets held by unconsolidated investments. There were no material other than temporary impairment losses recognized by any of the Company’sCompany's investments in unconsolidated real estate entities during the three and six months ended June 30, 2016March 31, 2017 and 2015.
