Summary of the yield curves used to discount the cash flows of insurance contracts
The table below sets out the yield curves used to discount the cash flows of insurance contracts for major currencies (converted at the spot rate). As a result of the execution of the Partial
Spin-off
of the Financial Services business, accumulated other comprehensive income related to insurance finance income (expenses) at the time of the execution was transferred to net income (loss) from discontinued operations as a loss in the consolidated statements of income. Therefore, yield curves are presented as of September 30, 2025.
