[1] | The expected life of SARs granted under the stock-based compensation plans is based on historical vested stock option and SAR exercise and post-vest forfeiture patterns and includes an estimate of the expected term for stock options and SARs that were fully vested and outstanding. |
[2] | The risk-free interest rate is based on the U.S. Treasury yield for a term consistent with the expected life of SARs in effect at the time of grant. |
[3] | The Company estimates the volatility of its common stock at the date of grant based on the historical volatility of the Companybs common stock for a period equivalent to the expected life of the SARs, which it believes is representative of the expected volatility over the expected life of the SARs. |
[4] | The Company expects to continue paying quarterly dividends at the same rate as the three months ended October 31, 2013. |
[5] | The expected-to-vest SARs are the result of applying the pre-vesting forfeiture rate assumptions to total outstanding SARs. |
[6] | The number of RSUs vested includes shares withheld on behalf of employees to satisfy statutory tax withholding requirements. |
