Answer:
The authorized common stock shares remain 1,000,000 shares.
Step-by-step explanation:
The authorized shares are not affected by movements in the shares, like issue of shares, repurchase, and resale of treasury stock shares. The authorized shares, therefore, represent the number of shares that the company is legally bound to issue without exceeding. The implication is that the company is free to issue shares less than or equal to the authorized shares, but it may not issue more than the authorized until it obtains a new authorization.
The movements are accounted for in separate accounts called Issued Common Stock Account and Treasury Stock Account. The treasury stock account is a contra account to the Common Stock.
