Final answer:
Reese Company should recognize compensation expense for 2015 on its books in the amount of $300.
Step-by-step explanation:
The compensation expense for 2015 that Reese Company should recognize on its books as a result of the option granted to Buchanan can be calculated by determining the fair value of the option at the grant date and allocating it over the service period. In this case, the fair value of the option is $3,600 and the service period is two years.
Since Buchanan exercised his option on September 1, 2015, and sold his shares on December 1, 2015, the compensation expense recognized for 2015 should be prorated based on the time he held the shares during that year. Using the fair value method, the compensation expense for 2015 should be calculated as follows: ($3,600 / 5 years) * [3 months / 12 months] = $300.
Therefore, as a result of the option granted to Buchanan, Reese should recognize compensation expense for 2015 on its books in the amount of $300.
