Share-based Payment Arrangement [Text Block]

In May 2013, the shareholders of the Company approved the 2013 Incentive Stock and Awards Plan (the “2013 Plan”), authorizing the granting of incentive stock options, non-qualified stock options, stock appreciation rights (“SARs”), restricted stock, performance shares and other stock based compensation. A total of 5,000,000 shares of common stock (subject to adjustment for expirations and cancellations of options outstanding from the previous plan) have been reserved for issuance under the 2013 Plan. All options and SARs have been or will be granted with exercise prices at least equal to the fair market value of the shares on the date of grant. At December 31, 2020, the Company had 2,675,107 shares of common stock available for grant of share-based compensation under the 2013 Plan.

Stock Options and Stock Appreciation Rights (“SARs”)

The Company grants stock options and stock-settled SARs to employees that allow them to purchase shares of the Company’s common stock. Stock options are also granted to outside members of the Board of Directors of the Company. The Company determines the fair value of stock options and SARs at the date of grant using the Black-Scholes valuation model. Assumptions regarding volatility, risk-free interest rate, expected term and dividend yield are required for the Black-Scholes model. The risk-free interest rate is based on the yield of a U.S. treasury bond with a similar maturity to the award’s expected life. The expected life for awards granted is based on the historical exercise patterns experienced by the Company when the award is made. The determination of expected stock price volatility for awards is based on historical Superior common stock prices over a period commensurate with the expected life. The dividend yield assumption is based on the history and expectation of the Company’s dividend payouts.

The following table summarizes significant assumptions utilized to determine the fair value of stock options and SARs:

All stock options and SARs granted prior to August 3, 2018 vested immediately when granted. Awards issued thereafter vest either one or two years after the grant date. Employee awards expire five years after the grant date, and those issued to directors expire ten years after the grant date. The Company issues new shares upon the exercise of stock options and SARs.
