Maturity analysis
The following table summarizes the estimated timing of the remaining undiscounted net cash outflows from insurance contract liabilities and investment contract liabilities and the contractual timing of the remaining undiscounted cash inflows arising from securities held in the insurance business as of March 31, 2024 and 2025. The cash flows of insurance contract liabilities are based on assumptions regarding morbidity rates, mortality rates, and lapse rates, which are consistent with the estimates used for the carrying
amounts.
