10.  EMPLOYEE BENEFIT PLANS

The Company provides an unfunded Supplemental Executive Retirement Plan (“SERP”) for certain members of its executive management. The Company uses a December 31 measurement date for the benefit obligations and a January 1 measurement date for its net periodic costs for the SERP. Variances from actuarially assumed rates will result in increases or decreases in benefit obligations and net periodic cost in future periods. Benefits expense under the SERP was $2 million for both of the three-month periods ended March 31, 2020 and 2019, respectively. The accrued benefit liability for the SERP totaled $74 million and $72 million at March 31, 2020 and December 31, 2019, respectively, and is included in other long-term liabilities on the condensed consolidated balance sheets. The weighted-average assumptions used in determining net periodic cost for the three months ended March 31, 2020 and March 31, 2019 were a discount rate of 3.1% and 4.2%, respectively, and an annual salary increase of 3.0%. The Company had equity investment securities in a rabbi trust generally designated to pay benefits of the SERP in the amounts of $78 million and $84 million at March 31, 2020 and December 31, 2019, respectively. These amounts are included in other assets, net on the condensed consolidated balance sheets.
