11. Earnings Per Share

The Company computes earnings per share using the treasury stock method unless the two-class method is more dilutive. The Company computed earnings per share for the three and nine months ended September 30, 2016 using the treasury stock method. Under the treasury stock method, basic earnings per share are computed by dividing net income available to shareholders by the weighted average number of common shares outstanding during the period, and diluted earnings per share are computed by dividing net income available to shareholders by the weighted average number of common shares outstanding during the period plus all potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalent would be anti-dilutive.

For the three and nine months ended September 30, 2015, the Company computed earnings per share using the two-class method because that method resulted in a more dilutive effect than the treasury stock method. The two-class method is an earnings allocation formula that determines earnings per share for common stock and participating securities according to dividends declared and participation rights in undistributed earnings. Under the two-class method, the Company’s unvested grants of restricted stock that contained non-forfeitable rights to dividends were treated as participating securities and were excluded from the computation of basic and diluted earnings per share. All shares of restricted stock granted since 2013 are not participating because the grant agreements contain provisions that dividends, if declared, will be forfeited if the grantee leaves the Company before the stock is vested.

Net income available to common shareholders and the weighted average number of common shares used to compute basic and diluted earnings per share were as follows:

For the three and nine months ended September 30, 2016 and 2015, certain common stock equivalents were excluded from the calculation of dilutive securities because their inclusion would either have been anti-dilutive or, for stock options, the exercise prices of those stock options were greater than the average market price of the Company’s common stock for the period. All of the Company’s non-participating unvested restricted shares were included in the computation of weighted average dilutive securities. The following table summarizes the shares of common stock underlying the Company’s unvested stock options and performance awards that were excluded from the calculation of dilutive securities:

Share Repurchases

During 2016, the Company’s Board of Directors approved two amendments to the share repurchase program (“Repurchase Program”), which increased the Repurchase Program from $67.5 million to $162.5 million and extended the term of the program through August 15, 2017. During the nine months ended September 30, 2016, the Company repurchased 4,227,541 shares of its common stock at a weighted-average price of $23.79 per share; 4,189,858 of those shares were purchased under its Repurchase Program for approximately $99.8 million. Additionally, the Company repurchased 37,683 shares of stock, for approximately $0.9 million, from its employees to satisfy tax obligations on shares vested under the LTIP. All of the shares repurchased were retired and returned to authorized but unissued stock.
