(2)(a) If the combined percentage or proportion of fault attributed to all persons immune from suit is less than 40%, the trial court shall reduce that percentage or proportion of fault to zero and reallocate that percentage or proportion of fault to the other parties and those identified under Subsection 78B-5-821(4) for whom there is a factual and legal basis to allocate fault in proportion to the percentage or proportion of fault initially attributed to each by the fact finder. After this reallocation, cumulative fault shall equal 100% with the persons immune from suit being allocated no fault.

(b) If the combined percentage or proportion of fault attributed to all persons immune from suit is 40% or more, that percentage or proportion of fault attributed to persons immune from suit may not be reduced under Subsection (2)(a).
