Answer: 6.0 million shares
Explanation: Six million shares would be the current number of shares of treasury stock after the transaction indicated above have all been accounted for. The treasury stock is defined as the issued stock of an incorporated company held by the company itself and the total issued stock for a company equals the sum of outstanding stock and treasury stock. When an incorporated company reissues treasury stock for more than it originally paid for the stock, it does not report a gain.
Given this, Treasury stock (shares held by the company) would be equal to 6.0 million shares
