| 2022 |  | 2021 |  | 2020
Dividend yield (1) | 1.8 | % |  | 1.8 | % |  | 2.0 | %
Expected volatility (2) | 28.8 | % |  | 27.6 | % |  | 27.5 | %
Risk-free interest rate (3) | 3.4 | % |  | 1.3 | % |  | 0.3 | %
Expected term of options (in years) (4) | 4.2 |  | 4.1 |  | 4.2
Weighted-average grant-date fair value | $ | 6.42 |  |  | $ | 6.59 |  |  | $ | 4.83 |
(1) Represents the Company's estimated cash dividend yield over the expected term of option grant. (2) Amount is determined based on analysis of historical price volatility of the Company's common stock. The expected volatility is based on the daily percentage change in the price of the stock over a period equal to the expected term of the option grant. (3) Represents the U.S. Treasury yield over the expected term of the option grant. (4) Represents the period of time that options granted are expected to be outstanding. Based on analysis of historical option exercise activity, the Company has determined that all employee groups exhibit similar exercise and post-vesting termination behavior.
