STOCK-BASED COMPENSATION. |
STOCK-BASED COMPENSATION | NOTE 9. STOCK-BASED COMPENSATION ​ On May 21, 2014, we adopted the 2014 Equity Incentive Plan (the “2014 Plan”). The purposes of the 2014 Plan are to attract and retain the best available personnel, to provide additional incentives to employees, directors and consultants and to promote the success of the Company’s business. The 2014 Plan is an “omnibus plan” under which stock options, stock appreciation rights, performance awards, dividend equivalents, restricted stock, and restricted stock units can be awarded to employees, directors and consultants of the Company. The 2014 Plan serves as the successor to our 1993 Employee Stock Option Plan, 1993 Executive Long-Term Incentive Plan and 1993 Directors’ Stock Option Plan (which plan terminated on June 13, 2013) (the “Predecessor Plans”). The 2014 Plan became effective as of May 21, 2014 and the remaining two Predecessor Plans terminated on that date (except with respect to awards previously granted under the Predecessor Plans that remain outstanding). ​ The maximum aggregate number of shares which may be issued pursuant to all awards under the 2014 Plan, and the Amendment No. 1 and Amendment No. 2 to the 2014 Plan includes 3,400,000 new shares and the shares available for grant or subject to outstanding awards under the Predecessor Plans. The share reserve as of December 31, 2020 is 1,167,236. By its terms, the 2014 Plan will expire in May 2024 after which no options may be granted unless the 2014 Plan is amended or replaced. ​ Pursuant to the terms of the 2014 Plan, either the Board or a committee designated by the Board is authorized to administer the plan. The administrator has the authority, in its discretion, to select employees, consultants and directors to whom awards under the 2014 Plan may be granted from time to time, to determine whether and to what extent awards are granted, to determine the number of shares or the amount of other consideration to be covered by each award (subject to certain limitations), to approve award agreements for use under the 2014 Plan, to determine the terms and conditions of any award (including the vesting schedule applicable to the award), to amend the terms of any outstanding award granted under the 2014 Plan (subject to certain limitations), to construe and interpret the terms of the 2014 Plan and awards granted, and to take such other action not inconsistent with the terms of the 2014 Plan as the administrator deems appropriate. ​ A summary of the stock option activity as of and for the year ended December 31, 2020 is presented below: ​ ​

​ Expense Measurement and Recognition: ​ The Company recognizes stock-based compensation for all current stock option award grants and for the unvested portion of previous stock option award grants based on grant date fair values. Unrecognized costs related to all stock option awards outstanding at December 31, 2020 totaled approximately $10.3 million and is expected to be recognized over a weighted average period of 2.4 years. ​ The Company uses historical data and projections to estimate expected employee, executive and director behaviors related to stock option exercises and forfeitures. ​ The Company estimates the fair value of each stock option award on the grant date using the Black-Scholes valuation model incorporating the assumptions noted in the following table. Option valuation models require the input of highly subjective assumptions, and changes in assumptions used can materially affect the fair value estimate. Option valuation assumptions for options granted during each year were as follows (dollars in thousands): ​ ​

​ The risk-free interest rate is based on the U.S. Treasury security rate in effect as of the date of grant. The expected lives of options are based on historical data of the Company. The Company has determined that an implied volatility is more reflective of market conditions and a better indicator of expected volatility as compared to the Company’s experience. ​ Reported stock-based compensation expense was classified as follows (in thousands) and it is included in the Operating expenses in the Consolidated Statement of Income: ​
