Share-based Payment Arrangement [Abstract]  
Table Of Weighted Average Black Scholes Fair Value Assumptions [Table Text Block]
The following summarizes the assumptions used to estimate the fair value of stock options granted during 2020, 2019 and 2018 and the resulting weighted average grant date fair value per stock option:
 202020192018
Weighted average risk-free interest rate0.48 %2.15 %2.78 %
Weighted average expected stock option term (in years)6.25 6.25 6.25 
Weighted average Company volatility45.08 %29.88 %26.92 %
Expected annual dividends per share$0.15 $0.15 $0.15 
Weighted average grant date fair value per stock option$23.05 $37.14 $51.66 

The risk-free interest rate is based on United States Treasury yields in effect at the date of grant for periods corresponding to the expected stock option term. The expected stock option term represents the weighted average period of time that stock options granted are expected to be outstanding, based on vesting schedules and the contractual term of the stock options. Company volatility is based on the historical volatility of the Company’s common stock over a period of time corresponding to the expected stock option term. Expected dividends are based on the anticipated common stock cash dividend rate for the Company at the time of grant; the dividend assumption for the stock options granted during 2020 was not affected by the Company’s suspension of its cash dividend beginning with the second quarter of 2020 in response to the impacts of the COVID-19 pandemic on its business and as a condition of the June 2020 Amendment, as such suspension was viewed as temporary.

The Company has continued to utilize the simplified method to estimate the expected term for its “plain vanilla” stock options granted due to a lack of relevant historical data resulting, in part, from changes in the pool of employees receiving stock option grants. The Company will continue to evaluate the appropriateness of utilizing such method.

Table of Weighted Average Monte Carlo Fair Value Assumptions Performance Awards [Table Text Block] The fair value of the awards granted was established for each grant on the grant date using the Monte Carlo simulation model.
The following summarizes the assumptions used to estimate the fair value of PSUs granted during 2020, 2019 and 2018 and the resulting weighted average grant date fair value per PSU:
202020192018
Weighted average risk-free interest rate0.19 %2.13 %2.62 %
Weighted average Company volatility51.86 %30.25 %29.78 %
Expected annual dividends per share$0.15 $0.15 $0.15 
Weighted average grant date fair value per PSU$64.89 $119.46 $159.53 
    
The risk-free interest rate is based on United States Treasury yields in effect at the date of grant for the term corresponding to the three-year performance period. Company volatility is based on the historical volatility of the Company’s common stock over a period of time corresponding to the three-year performance period. Expected dividends are based on the anticipated common stock cash dividend rate for the Company at the time of grant; the dividend assumption for the PSUs granted during 2020 was not affected by the Company's suspension of its cash dividend beginning with the second quarter of 2020 in response to the impacts of the COVID-19 pandemic on its business and as a condition of the June 2020 Amendment, as such suspension was viewed as temporary.

For certain of the awards granted, the after-tax portion of the award is subject to a holding period of one year after the vesting date. For such awards, the weighted average grant date fair value was discounted 15.94% in 2020, 6.20% in 2019 and 7.09% in 2018 for the restriction of liquidity, which was calculated using the Chaffe model.
