Mark received 10 ISOs at the time he started working for Hendricks Corporation five years ago when Hendricks’s price was $5 per share (each option gives him the right to purchase 10 shares of Hendricks Corporation stock for $5 per share). Now that Hendricks’s share price is $35 per share, he intends to exercise all options and hold all of his shares for more than year. Assume that more than a year after exercise, Mark sells the stock for $35 a share.

a. What are Mark’s tax consequences on the grant date, the exercise date, and the date he sells the shares assuming his ordinary marginal rate is 32 percent and his long-term capital gains rate is 15 percent?

b. What are Hendricks’s tax consequences on these dates assuming its marginal tax rate is 21 percent?
