401(k) Savings Plan
 
The Company has a retirement savings 401(k) plan covering substantially all employees. Employees may contribute up to the maximum legal limit with the Company matching up to 5% of the employee’s salary. Employer contributions charged to expense for the three months ended September 30, 2023 and 2022 totaled $93,000 and $74,000, respectively. Employer contributions charged to expense for the nine months ended September 30, 2023 and 2022 totaled $302,000 and $281,000, respectively.
 
Stock-Based Compensation
 
The Company adopted an equity incentive plan (the “Incentive Plan”) in September 2018. The Incentive Plan permits the grant of restricted stock units and nonqualified incentive stock options. The Incentive Plan will terminate in September 2028, if not extended. Compensation expense related to the Incentive Plan for the three months ended September 30, 2023 and 2022 totaled $565,000 and $341,000, respectively. Compensation expense related to the Incentive Plan for the nine months ended September 30, 2023 and 2022 totaled $1.7 million and $1.1 million, respectively. There were 637,371 shares available for future grants as of September 30, 2023.
 
The Company grants to employees and directors restricted stock units (RSUs) which vest ratably over one, three, four, five, or eight years and stock options which vest ratably over four years.  All RSUs and stock options are granted at the fair value of the common stock at the time of the award. The RSUs are considered fixed awards as the number of shares and fair value are known at the date of grant and the fair value at the grant date is amortized over the vesting and/or service period.
 
The Company uses newly issued shares for granting RSUs and stock options.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model and is based on certain assumptions including risk-free rate of return, dividend yield, stock price volatility and the expected term. The fair value of each option is expensed over its vesting period.

The following table shows the assumptions used for computing stock-based compensation expense under the fair value method on options granted during the period presented. There were no new grants for the nine months ended September 30, 2023.
