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.
执行价格<全年的平均价格，那么就有一个获利的机会,行权。
题中全年的平均价格=20
执行价格是25（converted shar price）还是30（year end price）如何区分？
