Given the following information, how many shares should be used when calculate the company's diluted EPS?
Company has 60,000 common shares outstanding all year and has 50,000 outstanding warrants all year, convertible into share each at $25 per share. the year end price of stock was $30,
amd the average price of the company's stock for the year was $20.
选项：
A. 65,000.
B. 60,000.
C. 5,000.
解释：
The average warrant price per share of $20 is less than the exercise price of $25, so the warrants are antidilutive. The total shares when calculating the company's diluted EPS consists of only the common stock for basic EPS.
option，convertible bond，covertible prefer shares都要先判断是否行权是吧？
