January 2010, Gigabyte Inc. granted 10,000 "at the money" employee stock options (i.E the exercise price was equal to the stock price on the grant date.) to align the compensation of the employees with financial performance of the company, the award will vest only if cumulative revenue over the following three year reporting period is greater than $100 million and if they are still employed. as of the date of the grant, management believe it is probable that the company will achieve cumulative revenue in excess of 100 million over the next three year period.

Each award has a grand - date fair value of $15. Gigabyte's valuation professionals have indicated that if the revenue target was factored in to the fair value assessment, the grant date fair value would be $10

gigabyte adopted ASC 718. Revenue in each of the next three years was as follows:

2010 : $30 million.

2011: 30 million

2012: 40 million
