Stock Appreciation Rights
No taxable income is reportable when a stock appreciation right with an exercise price equal to the fair market value of the underlying common shares on the date of grant is granted to a participant. Upon exercise, the participant will recognize ordinary income in an amount equal to the amount of cash received and the fair market value of any shares received. Any additional gain or loss recognized upon any later disposition of the shares would be capital gain or loss.
