Final answer:
Under the fair value method, no impact on Houser's stockholders' equity is recorded in 2010 since the compensation expense is recognized over the options' three-year vesting period starting January 1, 2011.
Step-by-step explanation:
The impact on Houser's total stockholders' equity for the year ended December 31, 2010, as a result of the stock option transaction under the fair value method is $0. This is because the total compensation expense is recognized over the vesting period, which is the period the executives earn the options. Since the vesting period begins on January 1, 2011, and spans a three-year period, no expense is recognized in 2010. Therefore, the correct answer is c. $0.
