On January 1, 2010, Roswall Corporation's common stock is selling for $55 per share. On this date, Roswall creates a compensatory share option plan for its 60 key employees. The plan document states that each employee may purchase 500 shares of its $10 par common stock for $55 per share after working for the company for three years. On this date, based on an option pricing model, Roswall estimates that each option has a value of $18. Historically, Roswall has experienced an employee turnover rate of 5% per year and, on the grant date it expects this rate to continue over the next three years. Because of lower turnover, at the end of 2011 Roswall changes its estimated turnover rate to 4% for the entire service period. At the end of 2012, the options vest for 54 employees. On January 13, 2013, ten executives exercise their options when the stock is selling for $75 per share.
