There were no stock options or stock-settled appreciation rights (“SSARs”) excluded from the computation of diluted net income per share for the three and nine months ended September 30, 2015 and 2014.
The Company has issued shares of purchased restricted common stock (“PRS”) which contain rights to nonforfeitable dividends while these shares are outstanding and thus are considered participating securities. Such securities are required to be included in the computation of basic and diluted earnings per share pursuant to the two-class method. The Company did not present the two-class method since the difference between basic and diluted net income per share for both unrestricted common shareholders and PRS shareholders was less than $0.01 per share for each period presented, and the number of PRS outstanding as of September 30, 2015 and 2014 was immaterial. Net income allocated to such PRS was $0.5 million and $0.6 million during the three months ended September 30, 2015 and 2014, respectively and $1.6 million and $1.9 million during the nine months ended September 30, 2015 and 2014, respectively.
