IFRS17 coverage units for CSM amortization

While IFRS 17 provides little guidance about coverage units, insurers may be able to find quick but reasonable choices from current modeling philosophy or certain existing standards such as U.S. GAAP. Insurers should carefully examine the consequences and reasonableness of those choices in light of the characteristics of their business as coverage units are very important factors for determining the future profit signature under IFRS 17.
