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 reviewed their assumptions, recognized variances between actual and forecasted results and updated the assumptions during fiscal 2025 and 2026 as follows.
 
   
Yen-denominated
insurance (First Sector)
During fiscal 2025 the Company and its subsidiaries updated expected mortality and lapse rates due to the higher-than-expected mortality and lapse rates.
 
 
During fiscal 2026 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 2025 the Company and its subsidiaries updated expected mortality and lapse rates due to the higher-than-expected mortality and lapse rates. 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 the Company and its subsidiaries believe further observations are needed to determine whether such an assumption is temporary or permanent.
During fiscal 2026 the Company and its subsidiaries updated expected mortality and lapse rates due to the higher-than-expected mortality and lapse rates. In addition, the relevant morbidity assumptions were updated because the actual morbidity excluding deemed hospitalization remained lower-than-expected ever after reclassification of the legal category of
COVID-19
by Japanese government.
 
   
Foreign currency denominated insurance
During fiscal 2025 the Company and its subsidiaries updated expected mortality rates due to the different-from-expected mortality rates. In addition, lapse rates were higher-than-expected due to the impact of rapid exchange rate fluctuations. However, the relevant lapse rates were not updated because the Company and its subsidiaries believe further observations are needed to determine whether such an assumption is temporary or permanent.
During fiscal 2026 the Company and its subsidiaries used mortality assumptions generally consistent with those of the previous fiscal year, reflecting that actual mortality was broadly in line with expectations. In addition, lapse rates were updated due to higher-than-expected lapse rates, although the impact of rapid exchange rate fluctuations has subsided.
The market data underlying the discount rate was updated quarterly for both the fiscal year ended March 31, 2025 and for fiscal 2026.
For the effect of the changes in assumptions on expected net premiums and expected future policy benefits, see “Effect of changes in cash flow assumptions” and “Effect of changes in discount rates” in the tables that represent balances of and changes in the liability for future policy benefits.

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.
