Summary of Undiscounted and Discounted Expected Future Gross Premiums and Future Benefits and Expenses | The following tables summarize the amount of undiscounted expected future gross premiums and expected future benefits and expenses and discounted (discounted at the current period discount rate) expected future gross premiums and expected future benefits and expenses by reporting segment and disaggregated by product type. Future gross premiums represent the expected amount of future premiums to be received. For limited-payment policies, the premiums are collected over a shorter period than the policy term over which benefits are provided. As a result, once the policy reaches premium paid-up status, the future gross premiums can be significantly less than the future benefit payments. Further, benefits and expenses are generally greater in the later years of a policy. These are the primary factors that result in future gross premiums lower than future benefit and expense payments for certain lines of business of the Company.
