Government employers are exempt from the security requirements. SIRA has discretion to seek additional security if it believes circumstances are warranted. For subsequent reviews for self-insurers with a central estimate of outstanding claim liability <$50 million — 150% of self-insurer liabilities including a prospective component for the 12 months post balance date. The prudential margin does not apply to government entities.

A retention amount under the above policy or policies, provided that it is within the range of $500,000 to $2,500,000 per event is acceptable to SIRA.

In such instances SIRA will require the self-insurer to undertake and provide an assessment of the likely cost of risk retention and the appropriateness of the level of retention sought as part of the approval process.
