Answer and Explanation:
The computation of the weighted-average number of shares outstanding in each cases is as follows:
a. At the time when the shares are issued at cash
= (303,000 × 12 ÷ 12) + (31,200 × 8 ÷ 12)
= 303,000 + 20,800
= 323,800 shares
b. At the time when the shares are issued in the stock dividend
= (303,000 × 12 ÷ 12) + (29,700 × 12 ÷ 12)
= 303,000 + 29,700
= 332,700 shares
