Employee Retirement and Benefit Plans
10- Employee Retirement and Benefit Plans	(10) Employee Retirement and Benefit Plans We sponsor a defined contribution 401(k) plan for all employees. Each participant may contribute certain amounts of eligible compensation. We make a matching contribution to the plan. Our contributions under this plan were $917,000, $845,000 and $752,000 in 2020, 2019 and 2018, respectively. The Company has a Nonqualified Deferred Compensation Plan for certain key management or highly-compensated employees. The plan allows for the deferral of salary and bonus compensation until retirement or other specified payment events occur. Employees’ deferred compensation amounts are deemed to be invested in certain investment funds, indexes or vehicles selected by our Compensation Committee and designated by each participant and their deferral balances are adjusted for earnings based upon the performance of these deemed investments. Our deferred compensation obligation under the plan was $1,544,000 and $3,266,000 at December 31, 2020 and 2019, respectively. These amounts are reflected in “Other Liabilities and Deferred Credits” in the accompanying consolidated balance sheets.
