9. | EMPLOYEE BENEFIT PLAN OBLIGATIONS
Our subsidiary, SC Transport Inc., contributes to the Central States, Southeast and Southwest Areas Pension Fund (the "Fund") based on an obligation arising from a collective bargaining agreement covering SC Transport Inc. employees and retirees. In Q3 2019, the Fund asserted that the subsidiary's absence of hiring additional union employees over the past ten years, coupled with restructuring of the subsidiary's business, constituted an adverse selection practice under the Fund and, if not remedied, will result in the assessment of a withdrawal liability. As a result of the Fund's assertion, SC Transport Inc. recorded a charge of $11.2, which is based on our best estimate from our analysis of available information and pension regulations which specify that the liability will be paid out in installments over a period of up to 20 years. The withdrawal liability was discounted using a rate of 3.5%. The amount that may ultimately be required to settle any potential obligation may be lower or higher than our estimated liability, which we will adjust as needed, if and when additional information becomes available.
