The superintendent shall by regulation describe the bases for adjustments in other situations, consistent with these relationships. Reasonable use of averaging methods shall be allowed. In particular, the regulation shall provide that a company shall approximate the percentage of its policies, contracts, premiums, and reserves with respect to which it has opted to make such adjustments, and shall derive adjustment factors such that, when such factors are applied to all of its business issued or in force, they will approximate the results that would be obtained if more precise calculations were made.
