The total number of weighted-average common stock equivalents excluded from the diluted per share computations due to their anti-dilutive effects for the year ended June 30, 2013 was 17,000. There were no such effects for the years ended June 30, 2015 and June 30, 2014 because the Company’s average stock price exceeded the exercise price of all shares outstanding. The calculation of diluted earnings per share for the year ended June 30, 2015 includes the shares underlying the performance-based RSUs granted in September 2014, September 2013 and September 2011. The shares underlying the performance-based RSUs granted in September 2012 are excluded in the calculation of diluted earnings per share for the years ended June 30, 2015, 2014 and 2013 as the performance metric associated with the shares was not met and no shares were issued under this grant. On May 1, 2014 the Company issued 1.4 million shares of common stock in accordance with the Convertible Notes and received 1.4 million shares of our common stock pursuant to the terms of the call option hedge transaction. The contingently issuable shares that may have resulted from the conversion of the Convertible Notes were included in the Company’s diluted share count for the fiscal years ended June 30, 2014 and 2013 because the Company’s average stock price during the first, second, and third quarters of the year ended June 30, 2014, and during the first, third and fourth quarters of the year ended June 30, 2013 was above the conversion price of $54.65 per share. During the year ended June 30, 2015 the Company issued 0.5 million shares of common stock in accordance with the Warrants. Pursuant to the terms of the Warrant transaction, the Warrants settled daily over 90 trading days which began in August 2014 and end in December 2014. The contingently issuable shares that may have resulted from the maturity of the Warrants were included in the computation of diluted earnings per share because the Company’s average stock price during the first and second quarters of the year ended June 30, 2015 and second, third, and fourth quarters of the year ended June 30, 2014 was greater than the Warrants’ exercise price of $68.31. The Warrants were excluded from the computation of the Company’s diluted earnings per share for the year ended June 30, 2013 because the Warrants’ exercise price was greater than the average market price of a share of Company common stock.
