Share-Based Compensation [Abstract]
Share-Based Compensation [Text Block]	Note 8 – Share-Based Compensation The Company recognized the following share-based compensation expense in its Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2022 and 2021: Three Months Ended Nine Months Ended September 30, September 30, 2022 2021 2022 2021 Stock options $ 533 $ 298 $ 1,269 $ 938 Non-vested stock awards and restricted stock units 1,783 1,277 4,998 3,963 Non-elective and elective 401(k) matching contribution in stock — — — 1,553 Director stock ownership plan 9 241 53 660 Performance stock units 875 491 2,314 1,327 Total share-based compensation expense $ 3,200 $ 2,307 $ 8,634 $ 8,441 Share-based compensation expense is recorded in SG&A, except for less than $ 0.1 million and $ 0.2 million for the three and nine months ended September 30, 2022, respectively, and $ 0.2 million and $ 0.7 million for the three and nine months ended September 30, 2021, respectively, recorded within Combination, integration and other acquisition-related expenses. Stock Options During the first nine months of 2022, the Company granted stock options under its long-term incentive plan (“LTIP”) that are subject only to time vesting over a three year period. For the purposes of determining the fair value of stock option awards, the Company used a Black-Scholes option pricing model and the assumptions set forth in the table below: March 2022 July 2022 Grant Grant Number of options granted 27,077 4,837 Dividend yield 0.80 % 0.79 % Expected volatility 38.60 % 40.47 % Risk-free interest rate 2.07 % 2.87 % Expected term (years) 4.0 4.0 The fair value of these options is amortized on a straight-line basis over the vesting period. As of September 30, 2022, unrecognized compensation expense related to all stock options granted was $ 2.0 million, to be recognized over a weighted average remaining period of 1.5 years. Restricted Stock Awards and Restricted Stock Units During the nine months ended September 30, 2022, the Company granted 35,846 non-vested restricted shares and 4,490 non- vested restricted stock units under its LTIP, which are subject to time-based vesting, generally over a three year period. The fair value of these grants is based on the trading price of the Company’s common stock on the date of grant. The Company adjusts the grant date fair value of these awards for expected forfeitures based on historical experience. As of September 30, 2022, unrecognized compensation expense related to the non-vested restricted shares was $ 5.9 million, to be recognized over a weighted average remaining period of 1.6 years, and unrecognized compensation expense related to non-vested restricted stock units was $ 1.0 million, to be recognized over a weighted average remaining period of 1.9 years. Performance Stock Units The Company grants performance-dependent stock awards (“PSUs”) as a component of its LTIP, which will be settled in a certain number of shares subject to market-based and time-based vesting conditions. The number of fully vested shares that may ultimately be issued as settlement for each award may range from 0 % up to 200 % of the target award, subject to the achievement of the Company’s total shareholder return (“TSR”) relative to the performance of the Company’s peer group, the S&P Midcap 400 Materials group. The service period required for the PSUs is three years and the TSR measurement period for the PSUs is generally from January 1 of the year of grant through December 31 of the year prior to issuance of the shares upon settlement. Compensation expense for PSUs is measured based on their grant date fair value and is recognized on a straight-line basis over the three year vesting period. The grant-date fair value of the PSUs was estimated using a Monte Carlo simulation on the grant date and using the following assumptions set forth in the table below: 2022 Grants Number of PSUs granted 18,462 Risk-free interest rate 2.11 % Dividend yield 0.93 % Expected term (years) 3.0 As of September 30, 2022, based on the conditions of the PSUs and performance to date for each award, the Company estimates that it will no t issue any fully vested shares as of the applicable settlement date of all outstanding PSUs awards. As of September 30, 2022, there was approximately $ 4.8 million of total unrecognized compensation cost related to PSUs which the Company expects to recognize over a weighted-average period of 2.0 years. Defined Contribution Plan The Company has a 401(k) plan with an employer match covering a majority of its U.S. employees. The Company matches 50 % of the first 6 % of compensation that is contributed to the plan, with a maximum matching contribution of 3 % of compensation. Additionally, the plan provides for non-elective nondiscretionary contributions on behalf of participants who have completed one year of service equal to 3 % of the eligible participants’ compensation. Beginning in April 2020 and continuing through March 2021, the Company matched both non-elective and elective 401(k) contributions in fully vested shares of the Company’s common stock rather than cash. There were no matching contributions in stock for the three and nine months ended September 30, 2022. For the nine months ended September 30, 2021, total contributions were $ 1.5 million.
