​ Equity Valuations: Stock option grant date fair values are calculated based on the Black-Scholes option pricing model as of date of grant. Adjustments have been made using stock option fair values as of each measurement date using the stock price as of the measurement date and updated assumptions (i.e., term, volatility, dividend yield, risk free rates) as of the measurement date. Performance-based restricted share unit grant date fair values are calculated using the stock price as of date of grant assuming target performance. Adjustments have been made using the stock price and performance accrual modifier as of year-end and as of the date of vest. Time-based restricted share unit grant date fair values are calculated using the stock price as of date of grant. Adjustments have been made using the stock price as of year-end and as of each vesting date in accordance with Item 402(v). The aggregate change in actuarial present value of accumulated benefit under pension plans reflects the amount reported for the applicable year in the SCT. ​
