Since Borealis Fit is a relatively new business with no prior experience data for group insurance, the insurer is likely to use manual rating. This method involves determining premiums based on standard rates for similar groups rather than the specific experience of the group itself. Manual rating is commonly applied when there is no claims history or insufficient data to support a credibility or experience rating. This aligns with LLQP guidelines, which outline manual rating as a default approach for groups without established claims experience​.
