On January 1, 2007 Pierce Company establishes a performance based share option plan for its 80 top executives. The terms of the plan are that each executive is granted a maximum of 200 options after completing a three-year service period. The exact number of options granted, however, depends on the percentage increase in sales over the three-year period. The terms are:
(1) If sales increase between 0 and 3%, each executive is granted 90 options;
(2) If, instead, sales increase between 4 and 6%, each executive is granted 140 options; and
(3) If, instead, sales increase at least 7%, each executive is granted the maximum number of options. Each option entitles the executive to acquire one share of the company’s $10 par common stock at a price of $45. The options expire at the end of six years.
On the grant date Pierce Company uses an option pricing model to estimate that the fair value of each share option is $15.50. Pierce’s employee turnover rate has averaged 6% per year and, on the grant date, it expects this rate to continue over the service period. At the end of 2008, because of lower turnover, Pierce revises its estimated annual turnover rate to 4% for the service period. At the end of 2009, options vest for 68 executives. On February 3, 2010, 50 executives exercise their options when the market price of the company’s common stock is $62 per share. During the remainder of the year, the market price declines so that at the end of 2010 the other 18 executives allow their options to expire.
Based on a projection of past trends, on the grant date Pierce Company estimates that its sales will increase about 5% by the end of 2009. This estimate appears accurate through 2008. However, in the last half of 2009, sales increase so much that at the end of 2009 Pierce determines that its total sales have increased by 7% over the three-year service period. All inventory is shipped by Pierce to its customers under FOB destination terms.
