Treasury Stock [Policy Text Block]
Treasury stock is stock that is repurchased by the issuing entity, reducing the number of outstanding shares in the open market. When shares are repurchased, they may either be cancelled or held for reissue. If not cancelled, such shares are referred to as treasury shares. The cost of the acquired shares is shown as a deduction in stockholders' equity. Dividends on such shares held in the entity’s treasury should not be reflected as income and are not shown as a reduction in equity. Depending on whether the shares are acquired for reissuance or retirement, treasury shares are accounted for under the cost method or the constructive retirement method. The cost method is also used when the reporting entity’s management has not made decisions as to whether the reacquired shares will be retired, held indefinitely or reissued. The Company elected for the repurchase of its common shares to be accounted for under the cost method. Under this method, the treasury stock account is charged for the aggregate cost of shares reacquired.
