问题如下：
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.
考点：股票稀释
题目问的是计算diluted EPS的分母是多少。
要计算考虑到所有稀释作用之后的发行在外普通股股数。
warrents就是option，25是执行价格，和全年平均价格20进行比较，执行价格高于全年平均股价，这种情况下是不会行权的，因此不会增加在外发行的普通股股数。
所以这道题目的warrants是没有稀释作用的。用来计算diluted EPS的分母就是60000股。
为什么执行价格高于平均价格就不行权？
