Assumptions for calculating the liability for future policy benefits include assumptions related to mortality, morbidity, lapse rates and discount rates. The Company and its subsidiaries recognized actual variances from expected experience and updated the assumptions during fiscal 2023 and 2024 as follows.
| • |  | Yen-denominated insurance (First Sector)
During fiscal 2023 the Company and its subsidiaries updated expected mortality and lapse rates due to the lower-than-expected mortality and lapse rates. During fiscal 2024 the Company and its subsidiaries updated expected mortality and lapse rates due to the lower-than-expected mortality and the higher-than-expected lapse rates.
| • |  | Yen-denominated insurance (Third Sector)
During fiscal 2023 the Company and its subsidiaries updated expected mortality and lapse rates due to the higher-than-expected mortality and the lower-than-expected lapse rate. The actual morbidity was higher than expected due to the impact of a significant amount of hospitalization benefits for deemed hospitalization caused by COVID-19. However, the relevant morbidity assumptions were not updated because benefits arising from such hospitalization benefits are not eligible for claim after reclassification of the legal category of COVID-19 by Japanese government. During fiscal 2024 the Company and its subsidiaries updated expected mortality and lapse rates due to the higher-than-expected mortality and the lower-than-expected lapse rate. The actual morbidity excluding deemed hospitalization was lower than expected ever after reclassification of the legal category of COVID-19 by Japanese government. However, the relevant morbidity assumptions were not updated because Company and its subsidiaries believe further observations are needed to determine whether such assumption is temporary or permanent.

During fiscal 2023 the Company and its subsidiaries updated expected mortality and lapse rates due to lower-than-expected mortality and higher-than-expected lapse rate. During fiscal 2024 the Company and its subsidiaries updated expected mortality rates due to lower-than-expected mortality rate. In addition, lapse rate was higher than expected due to the impact of rapid exchange rate fluctuations, but as this is considered to be a temporary factor, the Company and its subsidiaries removed the impact and updated expected lapse rates. The market data underlying the discount rate was updated quarterly for both the fiscal year ended March 31, 2023 and for fiscal 2024.

Deferred policy acquisition costs are amortized over the expected term of the policies on a constant-level basis. The assumptions used for the amortization of deferred policy acquisition costs are consistent with the assumptions for the liability for future policy benefits. The underlying assumptions for deferred policy acquisition costs and the liability for future policy benefits are updated at the same time. In addition, deferred policy acquisition costs are included in other assets in the consolidated balance sheets.
