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 Company’s common stock cash dividend rate at the date of grant.

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 2018, 2017 and 2016 and the resulting weighted average grant date fair value per PSU:

Certain of the awards granted in 2018, 2017 and 2016 are subject to a holding period of one year after the vesting date. For such awards, the grant date fair value was discounted 7.09% in 2018, 12.67% in 2017 and 12.99% in 2016 for the restriction of liquidity, which was calculated using the Chaffe model.
