Answer: The shares are deducted rather than added
Step-by-step explanation:
The adjustment to the weighted-average shares for retired shares is the same as for issuing new shares when the shares are added rather than deducted, the shares are treated as being acquired at the end of the year and the shares are treated as being acquired at the beginning of the year.
Therefore, the adjustment to the weighted-average shares for retired shares is the same as for issuing new shares except when the shares are deducted rather than added.
