Note 14, Stock-Based Compensation Plans:

We have issued and outstanding awards under two employee compensation plans, the 2014 Long Term Incentive Plan (the “2014 LTIP Plan”) and the 2004 Long Term Incentive Plan (the “2004 LTIP Plan”). No new awards may be granted under the 2004 LTIP Plan. Grants of stock-settled appreciation rights, restricted units, and performance units have been made to certain officers and key employees. All equity awards are settled in shares of Common Stock. As of December 31, 2019, approximately 560,000 shares were available for awards and options under the 2014 LTIP Plan.

The following table summarizes our equity award activity during the years ended December 31, 2019, 2018, and 2017:

The total fair value of service-based restricted stock awards that vested in 2019, 2018 and 2017 was approximately $2,491,000, $2,594,000 and $3,294,000, respectively. The aggregate intrinsic value of outstanding restricted stock awards was $4,734,000 at December 31, 2019. The restrictions on the service-based awards generally lapse or vest annually, primarily over four-year periods.

The total fair value of performance-based restricted stock awards that vested in 2019, 2018 and 2017 was approximately $1,389,000, $988,000 and $678,000, respectively. The aggregate intrinsic value of outstanding performance awards at December 31, 2019 expected to vest was $2,755,000. The performance awards are based on one-year performance periods but cliff vest in approximately three years from grant date.

The fair value for stock-settled appreciation rights were estimated at the date of grant using a Black‑Scholes pricing model. The aggregate intrinsic value of vested and outstanding stock-settled appreciation rights at December 31, 2019 was approximately $15,000. The total intrinsic value of stock-settled appreciation rights exercised was approximately $107,000 in 2019 and $284,000 in 2017.

The compensation for all awards is being charged to selling, general and administrative expense over the respective grants’ vesting periods, primarily on a straight-line basis, and was approximately $3,435,000, $4,358,000 and $3,818,000 in 2019, 2018 and 2017, respectively. Forfeitures are recognized as they occur. The tax expense (benefit) recognized related to all awards was approximately $98,000, $143,000 and $(192,000) in 2019, 2018, and 2017, respectively. As of December 31, 2019, the total compensation cost related to unvested equity awards was approximately $3,747,000 and is expected to be recognized over a weighted-average period of two years.
