[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 Company’s 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.
