A calculation of a former self-insurer’s liability amount must—
(a) be prepared under the actuarial standard; and
(b) apply a central estimate of the liability; and
(c) apply the risk free rate of return; and
(d) include claims administration expenses of 7% of the outstanding liability; and
(e) not include a prudential margin; and
(f) be based, as far as practicable, on the employer’s claims experience from claims incurred before the employer becomes or became a self-insurer; and
(g) be based on data as at the assessment day.
