(A) Earnings per share (EPS) for each quarter is computed using the weighted-average number of shares outstanding during the quarter, while EPS for the year is computed using the weighted-average number of shares outstanding during the year. Thus, the sum of the EPS for each of the four quarters may not equal the EPS for the year.
