Employee Benefit Plans	13. Employee Benefit Plans We provide a 401(k) plan to substantially all of our employees. Participating employees may defer up to the Internal Revenue Service limit per year based on the Internal Revenue Code. The annual contribution is determined by a formula set by our Board of Directors ("Board") and may include matching and/or discretionary contributions. The amount of the Company match is discretionary and subject to change. The retirement plans may be amended or discontinued at the discretion of the Board. Net contributions of $4,658, $5,206 and $4,205 were made by the Company to the 401(k) plan for the years ended March 31, 2020, 2019, and 2018, respectively. We have a deferred compensation plan (the “Deferral Plan”) for the benefit of those employees who qualify. Participating employees may defer up to 75% of their salary and 100% of their annual bonus for a Deferral Plan year. In addition, we may, but are not required to, make contributions into the Deferral Plan on behalf of participating employees, and the amount of the Company match is discretionary and subject to change. Each employee's deferrals together with earnings thereon are accrued as part of our long-term liabilities. Investment decisions are made by each participating employee from a family of mutual funds. The deferred compensation liability was $5,300 and $5,905 at March 31, 2020 and 2019, respectively. To offset this liability, we have purchased life insurance policies on some of the participants. The Company is the owner and beneficiary of the policies and the cash values are intended to produce cash needed to help make the benefit payments to employees when they retire or otherwise leave the Company. We intend to hold the life insurance policy until the death of the plan participant. The cash surrender value of the life insurance policies for deferred compensation was $7,029 and $9,546 at March 31, 2020 and 2019, respectively. The values of the life insurance policies and our related obligations are included on the accompanying consolidated balance sheets in long-term other assets and long-term deferred compensation, respectively. We made contributions of $74, $71 and $66 to the Deferral Plan for the years ended March 31, 2020, 2019, and 2018, respectively.
