Step-by-step explanation:
The impact on Gonzalez's net income for the year ended December 31, 2015 as a result of this transaction under the fair value method is a. $375,000 increase. To determine the impact on net income, we need to calculate the compensation expense recognized for the year. The Black-Scholes option pricing model determines total compensation expense to be $1,125,000. Since the options represent compensation for executives' services over a three-year period beginning January 1, 2015, one-third of the total expense is recognized each year. Therefore, the compensation expense recognized for the year ended December 31, 2015 would be $1,125,000 / 3 = $375,000, resulting in a $375,000 increase in net income for the year.
