Earnings Per Share [Abstract] |
Earnings Per Share [Text Block] | 7. NET INCOME PER SHARE The Company reports net income per share in accordance with ASC 260, “Earnings per Share”. Basic net income per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the year. Diluted net income per share is computed by dividing net income available to common shareholders by the weighted average number of shares outstanding and dilutive common share equivalents during the year. Common share equivalents include the number of shares issuable upon the exercise of restricted stock awards, less the shares that could be purchased under the treasury stock method. The following table reconciles the basic and diluted net income per share computations for fiscal year 2015 (amounts in thousands, except per-share amounts):
