Assume that on January 1, year 1, ABC, Inc. issued 5,000 stock options with an estimated value of $10 per option. Each option entitles the owner to purchase one share of ABC stock for $25 a share (the per share price of ABC stock on January 1, year 1 when the options were granted). The options vest at the end of the day on December 31, year 2. All 5,000 stock options were exercised in year 3 when the ABC stock was valued at $31 per share. Identify ABC’s year 1, 2, and 3 tax deductions and book-tax differences (indicate whether permanent and/or temporary) associated with the stock options under the following alternative scenarios:

a. The stock options are incentive stock options and ASC 718 applies to the options.

b. The stock options are non-qualified stock options and ASC 718 applies to the options.
