The provisions of section 72-301, Idaho Code, with respect to security, shall be met alternatively, by the employer demonstrating to the commission that security for its self-insured worker’s compensation program is covered by a cost reimbursement contract with the federal government for work performed in connection with the Idaho national laboratory including research, development, demonstration, testing, national security, defense, environmental cleanup or waste management if the cost reimbursement contract provides for the payment as otherwise required in this chapter. An employer that becomes self-insured under this section is not required to provide and maintain a security deposit, is not required to have a payroll history and is not required to have excess insurance coverage. In addition, because of the federal government reimbursement, the employer’s self-insurance program includes coverage for claims for events taking place before the effective date of the self-insured program, and no separate coverage or deposit for such claims is required.
