Answer:
3,202,000 shares.
Explanation:
Diluted earning per share (EPS) is an EPS that is calculated using both the common stock and all convertible securities like convertible preferred stock, convertible debt, equity options, warrants, or convertible bonds which are converted into common stock or equity.
Diluted EPS is different from an EPS that is calculated using only the common stock.
From the common stock, the number of shares that should be used in computing diluted earnings per share for the year ended December 31, 2021 are the addition of all the shares obtained as follows:
Number of shares for diluted EPS = 1,570,000 + 1,259,000 + 373,000
= 3,202,000 shares.
Therefore, the number of shares that should be used in computing diluted earnings per share for the year ended December 31, 2021 is 3,202,000 shares.
