Lаrkspur Biоtech Ltd. hаd 200,000 cоmmоn shаres outstanding at January 1. On April 1, the company issued 100,000 additional shares for cash. On October 1, the company declared a 20 percent stock dividend, which was recorded at fair value and distributed immediately. During internal review, one accountant treated the stock dividend as a current-period event only, while another restated all prior shares as if the dividend had occurred at the beginning of the year. In addition, management discussed a potential share consolidation later in the year, but no such transaction occurred. The controller is determining the appropriate weighted average number of shares for EPS purposes. What is the correct weighted average number of shares?
