Hi, I need some help with the first transaction. Can you explain to me why

Dr. Cash 960,000

Dr. Contributed Surplus - stock option 80,000

Cr .Common Shares 1,040,000

A person said that in feb, the company repurchased 40,000 shares at 28 and you're supposed to use that value of 28. with the current market value of 30. and take the difference 30-28= 2 and multiply it by the number of shares. Can you explain to me why? (if his/her answer is correct that is).

Second part of the question is: there's a

Dr. Compensation Expense 20,000

Cr. Contributed Surplus - Stock Options 20,000.

In the transaction of july 1 2010. The answer is used to record the cost of stock options for January to July of 2010. Can you explain to me why. Thanks
