17. Stock-Based Compensation

Long-term incentive plan

During 1995, the Company established the 1995 Long-Term Incentive Stock Option Plan (the Plan), which permits the granting of stock options (including incentive stock options and nonqualified stock options) stock appreciation rights, restricted or unrestricted stock awards, phantom stock, performance awards or any combination of these to employees, directors or consultants. The Plan was amended and restated effective April 22, 2016 and expires on April 21, 2026; the total number of shares that could be issued under the Plan is 7,500,000. As of December 31, 2020, 4,297,900 shares have been issued under the Plan, zero stock options and 1,719,732 restricted stock units (RSUs) were outstanding under the Plan, while 1,482,368 shares remain for future grants under the Plan.

The Company recognizes compensation expense on a pro rata straight-line basis over the requisite service period for stock-based compensation awards with both graded and cliff vesting terms. The Company recognizes the cumulative effect of a change in the number of awards expected to vest in compensation expense in the period of change. The Company has not capitalized any portion of its stock-based compensation. The Company's forfeiture rate is based on actuals.

During the years ended December 31, 2020 and 2019, the Company recognized $0.4 million and $1.4 million, respectively, of stock-based compensation expense under the fair value method. Accordingly, the Company recognized associated deferred income tax expense (benefits) of $220 thousand and $86 thousand, respectively, during the years ended December 31, 2020 and 2019. During the years ended December 31, 2020 and 2019, there were approximately zero and $93 thousand of stock-based compensation expense related to the change in fair value of cash-settled RSUs, which the Company accounts for as a liability.
