F. STOCK-BASED COMPENSATION:

The Company, from time to time, enters into separate non-vested share-based payment arrangements with employees and executive officers under the Incentive Compensation Plan approved by stockholders on May 18, 2010 and the 2017 Incentive Compensation Plan approved by shareholders on May 16, 2017, which authorized 50,000 and 150,000 shares, respectively, to be available for grants. The Compensation Committee of the Company’s Board of Directors approves all stock-based compensation awards for employees and executive officers of the Company. The Company grants restricted stock that is subject to continued employment and vesting conditions, but has dividend and voting rights, and uses the fair-market value of the Company’s common stock on the grant date to measure the fair value of the awards. The fair value of restricted stock is recognized as expense ratably over the requisite serviced period, net of estimated forfeitures.

During 2017, 2016, and 2015, the Company granted 7,837, 3,162 and 5,779 shares of restricted stock, respectively, to 22 employees and executive officers of the Company. Unless otherwise vested early in accordance with the Incentive Compensation Plans, the restricted stock vests on specified dates in 2020 through 2023, subject to the recipients’ continued employment or service through each applicable vesting date.

The Company recognized pre-tax compensation expense in the Consolidated Statements of Comprehensive Income related to stock-based compensation of $545,000, $391,000, and $333,000 in 2017, 2016, and 2015, respectively. As of December 31, 2017, there was approximately $1,432,000 of unrecognized compensation cost related to the restricted stock awards that is expected to be recognized over a weighted-average period of 3.8 years. There were 6,492, 1,284, and 2,570 shares of restricted stock that vested during 2017, 2016, and 2015, respectively.
