A generally accepted actuarial reserving method or other reasonable method if the method is approved by the commissioner before the statement date, or a combination of methods as described in this section, may be used to estimate all claim liabilities. The methods used for estimating liabilities generally may be aggregate methods, or various reserve items may be separately valued. Approximations based on groupings and averages may also be employed. Adequacy of the claim reserves, however, must be determined in the aggregate.
