Stock Compensation Plans |
NOTE 10 - STOCK COMPENSATION PLANS
At DecemberÌý31, 2023, we had outstanding awards under three share-based compensation plans: the 2021 Equity Plan, the A&R 2015 Equity Plan and the 2012 Amended Equity Plan. As of DecemberÌý31, 2023, there were 23.0 million remaining shares available for grant under the 2021 Equity Plan. No additional grants were issued from the 2012 Amended Equity Plan or the A&R 2015 Equity Plan after the date of approval of the 2021 Equity Plan; however, all awards previously granted under the predecessor plans will continue in accordance with the terms of the outstanding awards.
Upon vesting of share-based compensation awards, we issue shares from treasury shares before issuing new shares. Forfeitures are recognized when they occur.
STOCK-BASED COMPENSATION EXPENSE
The following table summarizes the total compensation expense recognized for stock-based compensation awards:
The total compensation cost related to outstanding awards not yet recognized is $53Ìýmillion at DecemberÌý31, 2023. This expense is expected to be recognized over the remaining weighted-average period of 1.7 years.
PERFORMANCE SHARES
The following table summarizes the performance award activity:
The outstanding performance shares vest over a period of three years and are intended to be paid out in common shares. Performance is measured on the basis of relative TSR for the period and measured against the constituents of the S&P Metals and Mining ETF Index. The number of shares actually earned at the end of the three-year period will vary, based on performance, from 0% to 200% of the number of performance shares granted.
We value our performance shares using a Monte Carlo simulation on the grant date. A correlation matrix of historical and projected stock prices was developed for both the Company and its predetermined peer group of metals and mining companies. The fair value assumes that the performance objective will be achieved. The expected term of the grant represents the time from the grant date to the end of the service period. We estimate the volatility of our common shares and that of the peer group of metals and mining companies using daily price intervals for all companies. The risk-free interest rate is the rate at the grant date on zero-coupon government bonds, with a term commensurate with the remaining performance period.
RESTRICTED STOCK UNITS
The following table summarizes the restricted stock units activity:
We value our restricted stock units using the closing price of our common shares on the grant date. All of the outstanding restricted stock units are subject to continued employment, are retention based, and are payable in common shares or cash in certain circumstances at a time determined by the Compensation Committee at its discretion. Most restricted stock units were granted under three-year cliff vesting terms.
STOCK OPTIONS
The following table summarizes the stock option activity:
Stock options granted to date generally vest over a period from to three years with an expiration date at ten years from the date of grant. The total intrinsic value of options exercised in 2023 was $1 million and the amount in 2022 was $3 million. As of DecemberÌý31, 2023, all outstanding options were exercisable. For options outstanding at DecemberÌý31, 2023, the weighted-average remaining contractual life was 2.1 years and the aggregate intrinsic value was $5 million.
The fair value of stock options is estimated on the date of grant using a Black-Scholes model using the grant date price of our common shares, the option exercise price, the option’s expected term, the volatility of our common shares, the risk-free interest rate and the dividend yield over the option’s expected term.
NONEMPLOYEE DIRECTORS
Our nonemployee directors are entitled to receive restricted share awards under the Directors’ Plan. For 2023, 2022 and 2021, nonemployee directors were granted a specified number of restricted shares, with a value equal to $140,000, $140,000 and $120,000, respectively. The number of shares is based on the closing price of our common shares on the date of the Annual Meeting. The restricted share awards issued under the Directors' Plan generally vest 12 months from the grant date. The awards are subject to any deferral election and the terms of the Directors’ Plan and an award agreement.
