Share-based Payment Arrangement, Noncash Expense [Abstract] |
Stock-Based Compensation | STOCK-BASED COMPENSATION The Company’s 2014 Equity Incentive Plan authorizes the issuance of stock options, stock appreciation rights, restricted stock units, restricted stock, performance awards, dividend equivalent rights and other stock-based awards, as well as cash-based awards to employees, officers, directors and other individuals providing services to the Company or its affiliates. The plan authorizes the issuance of up to 1,200,000 shares of Class A Common Stock. As of December 31, 2020, there were 374,478 shares available for future awards, including approximately 120,000 shares associated with awards that were terminated or cancelled without being exercised. A summary of stock-based compensation costs follows (in millions):
| Year Ended December 31,
| 2020 |  | 2019
Notional stock units and stock appreciation rights | $ | 6.6 |  |  | $ | 1.1 |
Restricted stock units | 0.4 |  |  | 0.2 |
Stock options | 0.1 |  |  | 0.1 |
Total stock-based compensation costs | $ | 7.1 |  |  | $ | 1.4 |
Total recognized tax benefit | $ | — |  |  | $ | — |
The total recognized tax benefit is reported at the federal statutory rate net of the tax valuation allowance. Notional stock units for participating executives for the three-year period ended December 31, 2018, under the 2016 Executive Incentive Plan were paid in cash in 2019 totaling $1.0 million. Notional stock units are a component of the 2019 Executive Incentive Plan for the three-year period ending December 31, 2021 with an interim payment targeted for 2021 and the final payment targeted for 2022. Notional stock units and stock appreciation rights were granted to participating executives for the three-year period ending April 26, 2023. The notional stock units and stock appreciation rights may be payable in common stock, cash or a combination of both at the discretion of the Board of Directors. Since the awards are likely to be settled with cash payments, compensation cost for notional stock units and stock appreciation rights are re-measured each reporting period based on the trading price of the Company’s common stock and the cumulative vested costs are accrued in Accounts Payable and Accrued Liabilities or Other Long-Term Liabilities based on the anticipated payment date. Compensation cost for restricted stock units and stock options is measured at the grant date, based on the fair value of the award, and is recognized on a straight-line basis over the requisite service period. As of December 31, 2020, there was $0.3 million of unrecognized compensation cost, adjusted for actual forfeitures, related to non-vested stock-based payments granted, of which $0.2 million relates to restricted stock units and $0.1 million relates to stock options. That cost is expected to be recognized over a weighted-average period of 12 months. Restricted Stock Units Non-employee, independent directors are granted restricted stock units as part of their compensation for serving on the Board of Directors. Settlement of these restricted stock units is made in shares of Class A Common Stock only upon the director’s retirement or other end of service. The restricted stock units generally vest over one year; however, vesting is accelerated upon (1) the director attaining eligibility for retirement, (2) termination of the director’s service by reason of death or disability, or (3) a change in control. As of December 31, 2020, approximately 262,000 shares of restricted stock units could potentially be converted to Class A Common Stock once vested and settled. The fair value of restricted stock units is determined based on the closing price of Class A Common Stock on the grant date. Compensation cost for restricted stock units is amortized to expense on a straight-line basis over the vesting period. Stock Options The intrinsic value of an option, if any, represents the excess of the fair value of the common stock over the exercise price. The fair value of stock option awards is estimated using the Black-Scholes option pricing model, which includes a number of assumptions including Centrus’ estimates of stock price volatility, employee stock option exercise behaviors, future dividend payments, and risk-free interest rates. The expected term of options granted is the estimated period of time from the beginning of the vesting period to the date of expected exercise or other settlement, based on historical exercises and post-vesting terminations. Centrus has estimated the expected term using the simplified method described in SEC Staff Accounting Bulletin No. 107/110, Share-Based Payment, due to the lack of historical exercise and post-vesting termination information available for the Company since its reorganization. Future stock price volatility is estimated based on the Company’s historical volatility. The risk-free interest rate for the expected option term is based on the U.S. Treasury yield curve in effect at the time of grant. No cash dividends are expected in the foreseeable future and, therefore, an expected dividend yield of zero is used in the option valuation model. The Company recognizes forfeitures as they occur. Compensation expense is recognized for stock option awards that are expected to vest. Assumptions used in the Black-Scholes option pricing model to value option grants follow. There were no option grants in the year ended December 31, 2020.
