Upon vesting, the value of the restricted stock units, restricted stock awards and performance shares are paid to each grantee in the form of shares or cash.

The weighted-average grant-date fair value of stock options granted during the six months ended June 30, 2014 was $11.50 per stock option. The fair value of each stock option granted was estimated on the grant date using the Black-Scholes option pricing model. The following weighted-average assumptions were used in computing the fair value of the stock options granted: expected volatility of 34.7%; expected life of five years; dividend yield of 4.4%; risk-free interest rate of 1.6%; and estimated forfeiture rate of 12%. The expected life of the stock options granted was estimated using the historical exercise behavior of employees. The expected volatility was generally based on historical volatility as calculated using historical data during the five years prior to the grant date.
