[1] Through June, 2012 expected volatility was a weighted-average of historical volatility and implied volatility. In July 2012, the Company eliminated the implied volatility aspect of this calculation and began utilizing historical volatility alone.
[2] Risk-free interest rate is based on the U.S. Treasury yield curve with respect to the expected life of the award.
[3] For awards that follow the 20% per year vesting schedule, expected life is a weighted-average that includes historical settlement data of the Company's equity awards and a hypothetical holding period for outstanding awards. Due to lack of historical settlement data on awards that follow the 50% vesting at each of years four and five, expected life of these awards is calculated under the simplified method.
[4] The Company historically has not paid dividends.
[5] Grant price is the closing price of the Company's common stock on the date of grant.Table 3
