(1) If an order is made under section 131B(1)(b) (a) an employer is not liable to pay compensation under this Act for an injury or disease arising out of the act of terrorism specified in the order; and(b) the same claims that would, but for this section, be made against an employer may be made against the Nominal Insurer.(2) Any such claim against the Nominal Insurer must be made within 90 days after the day on which the order is made.(3) As soon as practicable after the period referred to in subsection (2) elapses, the Nominal Insurer, on the advice of an actuary, is to estimate (a) the total amount that would, if subsection (4) did not apply, be payable by the Nominal Insurer in respect of all workers on account of its liability for the act of terrorism specified in the order; and(b) if that amount exceeds $25 million, the reduction factor by which that amount would need to be multiplied to limit it to $25 million.(4) If the Nominal Insurer determines a reduction factor, the amount that the Nominal Insurer would, but for this section, be required to pay on account of its liability for the act of terrorism specified in the order is reduced by multiplying it by the reduction factor.
