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 ratably over the requisite service period, or vesting period. 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 six months ended June 30, 2017 and 2016 were as follows:

Employee Activity - Performance Shares

The Company annually grants performance shares to key employees.  Under the terms of the performance share agreements, following the end of a three-year performance period, the Company will issue to the employees a calculated number of common stock shares based on the three year performance of the Company’s total shareholder return as compared to the total shareholder return of a selected peer group.  No shares may be issued if the Company's total shareholder return outperforms 30% or less of the peer group, but the number of shares issued may be doubled if the Company's total shareholder return 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:

Employee Activity - Employee Stock Purchase Plan
Under the 2005 Employee Stock Purchase Plan (the “ESPP”), which has been approved by shareholders, the Company is authorized to issue up to a remaining 376,625 shares of common stock to employees of the Company. These shares may be issued at a price equal to 90% of the lesser of the market value on the first day or the last day of each six-month purchase period. Common stock purchases are paid for through periodic payroll deductions and/or up to two large lump sum contributions. For the six months ended June 30, 2017, participants under the plan purchased 5,188 shares at an average price of $43.59 per share. For the six months ended June 30, 2016, participants under the plan purchased 5,592 shares at an average price of $38.50 per share. The weighted-average fair value of each purchase right under the ESPP granted for the six months ended June 30, 2017, which is equal to the discount from the market value of the common stock at the end of each six month purchase period, was $9.69 per share. The weighted-average fair value of each purchase right under the ESPP granted for the six months ended June 30, 2016, which is equal to the discount from the market value of the common stock at the end of each six month purchase period, was $6.03 per share. Share-based compensation expense of $51 and $34 was recognized during the three and six months ended June 30, 2017 and 2016, respectively.
