Compensation and Employee Benefit Plans [Text Block] | (10) EMPLOYEE BENEFITS We have no defined benefit pension plans or post-retirement benefit plans. We offer our employees a 401(k) Plan, where we match 100% of the first 4% that an employee contributes and a discretionary Deferred Bonus Plan for certain key employees. We also offer health benefits to all employees and their families. We have 2,274 participants in our employee health plan. The plan does not cover dental, vision, short-term or long-term disability. These coverages are available on a voluntary basis. We bear some of the risk of our employee health plans. Our health claims are capped at $200,000 per person with a maximum annual exposure of $16.6 million not including premiums. Our employee benefit expenses for the years ended December 31 are below (in thousands):
|  | 2021 |  |  | 2020 |
Health benefits, including premiums |  | $ | 13,084 |  |  | $ | 13,173 |
401(k) matching |  |  | 1,946 |  |  |  | 1,797 |
Deferred bonus plan |  |  | 698 |  |  |  | 679 |
Total |  | $ | 15,728 |  |  | $ | 15,649 |
Of the amounts in the above table, $15.2 million and $15.0 million are recorded in operating costs and expenses for 2021 and 2020, respectively with the remainder in SG&A. Our mine employees are also covered by workers’ compensation and such costs for 2021 and 2020, were approximately $2.9 million and $1.9 million, respectively, and are recorded in operating costs and expenses. Workers’ compensation is a no-fault system by which individuals who sustain work-related injuries or occupational diseases are compensated. Benefits and coverage are mandated by each state which includes disability ratings, medical claims, rehabilitation services, and death and survivor benefits. We are partially self-insured for such claims, however, our operations are protected from these perils through stop-loss insurance policies. Our maximum annual exposure is limited to $1 million per occurrence with a $4 million aggregate deductible. Based on discussions and representations from our insurance carrier, we believe that our reserve for our workers’ compensation benefits is adequate.
