Schedule of Fair Value Assumptions of SARS | The fair value of a SARs award is determined on the date of grant using the Black-Scholes-Merton valuation model with the following weighted average assumptions for the years ended December 31:
| 2020 |  | 2019 |  | 2018
Expected dividend yield (1) | — | % |  | — | % |  | — | %
Expected stock price volatility (2) | 23 | % |  | 21 | % |  | 21 | %
Risk-free interest rate (3) | 1.5 | % |  | 2.5 | % |  | 2.5 | %
Expected life in years (4) | 4.68 |  | 4.59 |  | 4.52
(1)The expected dividend yield assumption was based on both the Company’s historical and anticipated dividend payouts. Historically, the Company has not paid cash dividends on its Common Stock. (2)The determination of expected stock price volatility was based on both historical Common Stock prices and implied volatility from publicly traded options in the Common Stock. (3)The risk-free interest rate was based on the yield of a U.S. Treasury security with a maturity similar to the expected life of the award. (4)The expected life represents the Company’s estimate of the weighted average period of time the SARs are expected to be outstanding (that is, the period between the service inception date and the expected exercise date).
