Answer:
The weighted-average number of shares outstanding = 1,699,025
Step-by-step explanation:
January 1, 459,000 common stocks x 1.1 (stock dividend) x 3 (stock split) = 1,514,700 stocks
February 1, issued 123,000 common stocks = 123,000 x 1.1 (dividend) x 3 (split) x 11/12 (time) = 372,075 stocks
May 1 acquired 101,000 treasury stocks = -101,000 x 8/12 (time) x 3 (split) = -202,000 stocks
October 1, reissued 57,000 treasury stocks = 57,000 x 3/12 (time) = 14,250 stocks
The weighted-average number of shares outstanding = 1,514,700 + 372,075 -202,000 + 14,250 = 1,699,025 stocks
