At September 30, 2011, the remaining weighted-average contractual term was 1.2 years.  The weighted-average grant-date fair value of shares granted was $26.30 and $26.15 for the three months ended and year to date September 30, 2011, respectively.  There were no shares granted for the three months ended September 30, 2010.  The weighted-average grant-date fair value of shares granted year to date September 30, 2010, was $23.37.  At September 30, 2011, there was $4.0 million of total unrecognized compensation expense, net of forfeiture rates, related to performance shares granted under the Long-Term Incentive Plan, which will be recognized over the remaining weighted-average contractual term.  The total fair value of performance shares earned and paid year to date September 30, 2011 and 2010, was $0.8 million and insignificant, respectively.
 
The fair value of performance share awards is estimated using a Monte Carlo simulation technique that uses the closing stock price at the valuation date and incorporates assumptions for inputs of expected volatilities, dividend yield and risk-free rates.  Expected volatility is based on daily stock price change during a historical period commensurate with the remaining term of the performance period of the grant.  The risk-free rate is based upon the rate at the time of the evaluation for zero-coupon government bonds with a maturity consistent with the remaining performance period of the grant.  The dividend yield is based on the most recent dividends paid and the actual closing stock price on the valuation date.  For shares granted in 2011, inputs for expected volatility, dividend yield and risk-free rates ranged from 28%-30%, 3.98%-4.35%, and 0.61%-1.15%, respectively.
