Share-Based Payments

The Company’s general practice has been to make a single annual grant of share-based compensation to key employees and to make other employee grants only in connection with new employment or promotions.  Forms of share-based compensation granted to employees by the Company include stock options, non-vested shares of common stock (“non-vested share”), and performance shares.  The Company also typically makes a single annual grant of non-vested shares to non-employee directors in conjunction with the annual election of non-employee directors to the Board of Directors.  Share-based compensation is based on the grant date fair value of the instrument and is recognized, net of estimated forfeitures, ratably over the requisite service period, or vesting period. The Company estimates forfeitures based upon historical experience.  All share-based compensation expense is recognized in salaries, wages and employee benefits.

Employee Activity - Stock Options
 
Stock option grants to employees generally expire seven years from the grant date and typically vest ratably over a three-year period.  The Company used the Black-Scholes option-pricing model to estimate the grant-date fair value of options granted.  The weighted-average fair value of options granted and assumptions used to estimate their fair value during the three months ended March 31, 2016 and 2015 were as follows:

Employee Activity - Performance Shares

The Company annually grants performance shares to key employees.  Under the terms of the performance share agreements, on the third anniversary of the grant date, the Company will issue to the employees a calculated number of common stock shares based on the three year performance of the Company’s common stock share price as compared to the share price performance of a selected peer group.  No shares may be issued if the Company's share price performance outperforms 30% or less of the peer group, but the number of shares issued may be doubled if the Company's share price performs better than 90% of the peer group.  The fair value of the performance shares was estimated using a Monte Carlo simulation. The weighted average assumptions used in the Monte Carlo estimate were as follows:
