Key Input Assumptions Used in the Black-Scholes Option-Pricing Model | The following table summarizes the key input assumptions used in the Black-Scholes option-pricing model to estimate the fair value of unit options granted for the nine months ended September 30, 2022 and 2021:
| ​ | ​ | Nine Months Ended September 30,
| ​ | ​ | 2022 | ​ | ​ | 2021
Expected life of units (in years)(1) | ​ | ​ | 4.57 - 4.61 | ​ | ​ | 4.55 - 4.61
Expected unit price volatility(2) | ​ | ​ | 56.39% - 60.87% | ​ | ​ | 48.20% - 56.46%
Risk free interest rate(3) | ​ | ​ | 1.37% - 3.05% | ​ | ​ | 0.32% - 0.78%
Expected dividend yield(4) | ​ | ​ | —% | ​ | ​ | —%
Weighted average grant-date fair value per unit of unit options granted | ​ | ​ | $2.75 - $5.81 | ​ | ​ | $1.80 - $2.17
Fair value per common unit | ​ | ​ | $5.89 - $11.13 | ​ | ​ | $4.50 - $4.98
(1) | The expected term for award is determined using the simplified method, which estimates the expected term using the contractual life of the option and the vesting period.
(2) | Expected volatility is based on historical volatilities of a publicly traded per group over a period equivalent to the expected term of the awards.
(3) | The risk-free interest rate is based on the U.S. Treasury yield of treasury bonds with a maturity that approximates the expected term of the awards.
(4) | Prior to June 10, 2022, the Company has not historically paid cash dividends on its common units. On June 10, 2022, the Company’s Board of Managers approved a special distribution as described in Note 9, and does not expect to pay any normal course cash dividends on its common units in the foreseeable future.
