Issued by: Atkore Policy Steering Committee Approved: Reviewed and approved 1/3/2022 2 Eligibility Determination of eligibility for severance pay is at the sole and exclusive discretion of the Company. Regular, full-time salaried exempt and non-exempt employees with at least 6 months continuous service are typically eligible for severance pay when they are involuntarily separated for one of the following reasons: • Lack of work or reduction in the workforce; • Facility closure or sale, unless the Employee is offered a reasonably comparable position and compensation and benefits by the Company or by the successor company. Reasonableness is determined solely and exclusively by the Company; • The Employee’s worksite relocates more than 50 miles, and the Employee is not offered relocation; • The Employee refuses relocation to a job which is more than 50 miles from the Employee’s current worksite; and • Any other reason determined by the Company to warrant severance. Additionally, if an employee is terminated for inability to perform his or her duties despite reasonable efforts by the Employee, he/she will be eligible for severance at 50% of the weekly schedule in Table 1 above. Severance pay is not provided to any employee who voluntarily terminates, is temporarily laid-off, or who is terminated for cause. “For cause” includes but is not limited to; dishonesty, insubordination, misconduct, or violation of a Company policy. Severance Pay A valid and enforceable legal release, in a form acceptable to the Company, must be in effect prior to severance pay and benefits being paid. Severance will be paid in a lump sum after the revocation period, which follows the signing of the release of claims has expired. The lump-sum payment is subject to normal payroll taxes and withholdings. Health Benefit Continuation The Company will pay the employer portion of the cost of the medical, prescription drug, and dental coverage provided the Employee properly elects COBRA continuation coverage and continues to pay the applicable employee contribution. The Company paid health, and welfare benefits will be provided for a period equal to the applicable severance period outlined in Table 1 above or until Employee is eligible for alternative coverage, whichever occurs first. Earned Compensation & Benefits Any wages, salary, or commissions and vacation earned as of the date of termination will be paid as soon as practical after termination or consistent with applicable State law, whichever is sooner. Outplacement Services Outplacement services will typically be made available to eligible separated employees. The purpose of outplacement is to assist separated employees with securing future employment. Outplacement services include guidance with resume preparation, interviewing skill training, and networking techniques. The vendor and the services provided will be determined by the Company. Cash will not be provided in lieu of outplacement services.
