Significant judgments and estimates for insurance contracts
As a result of the execution of the Partial Spin-off of the Financial Services business, SFGI, which operates the Financial Services business, has been excluded from consolidation. Therefore, figures in this section are presented only as of March 31, 2025, September 30, 2025 or for the fiscal year ended March 31, 2025.
 
i)
Measurement methods and inputs for insurance contracts
The methods and main inputs used to measure insurance contracts are as follows:
 
 
  
  Weighted average (%)  
 
 
  
March 31
 
 
  
  2025  
 
Mortality rates
     1.03
Lapse and surrender rates
     3.80
Sony estimates the mortality and morbidity rates based on the historical and most recent actual outcomes and analyzes the historical experience and trends in data using statistical methods. When estimating the mortality and morbidity rates for each group of insurance contracts, Sony takes into account the characteristics of policyholders including gender, health conditions and smoking habits and the characteristics of the group of insurance contracts such as the selective effects over time. The estimates are revised in a timely manner to reflect changes in lifestyle, as well as changes in social conditions such as improvement of mortality and morbidity rates in the future.
Sony estimates the lapse and surrender rates based on the historical and most recent actual outcomes and determines the probability-weighted lapse and surrender rates for each group of insurance contracts by analyzing historical experience and trends in data using statistical methods. Lapse and surrender rates are estimated, taking into account both ordinary and dynamic lapses, and reflect the tendency to higher surrender rates when the yield on contracts increases or exceeds the guaranteed minimum for certain insurance contracts. In determining the lapse and surrender rates, historical actual data is considered. If there is no or little historical actual data, the actual results of similar products as well as domestic and overseas practical trends are used as reference.
Sony projects estimates of future expenses based on the current expense levels. The expenses comprise expenses directly attributable to the group of insurance contracts, including the allocation of fixed and variable overhead expenses. In addition, Sony applies inflation adjustments to the estimated expenses in future.
 
 
ii)
Discretionary participation features of future cash flows
For certain participating insurance contracts other than direct participating contracts, the effect of discretionary changes on the fulfillment cash flows is adjusted in the CSM. Although Sony has discretionary participation features related to the investment policy for these contracts, the investment policy is established based on the market conditions. Therefore, the effect of changes in assumptions that relate to financial risk on the investment policy is included in insurance finance income or expenses. In addition, since the dividend policy can be changed at Sony’s discretion, the effect of changes in the dividend policy on the fulfillment cash flows is adjusted in the CSM.
 
iii)
Risk adjustments for
non-financial
risk
Risk adjustments for
non-financial
risk are determined to reflect the compensation that each insurance subsidiary would require for bearing
non-financial
risk, and are allocated to groups of insurance contracts based on an analysis of the risk profiles of the groups. Risk adjustments for
non-financial
risk reflect the diversification benefits, in a way that is consistent with the compensation that the insurance company would require and that reflects its degree of risk aversion.
The risk adjustments for
non-financial
risk are determined mainly using a cost of capital technique. In applying a cost of capital technique, Sony determines the risk adjustment for
non-financial
risk by applying a
cost-of-capital
 rate to the amount of capital required for each future reporting date and discounting the result using risk-free rates adjusted for illiquidity. The required capital is determined by estimating the probability distribution of the present value of future cash flows from insurance contracts at each future reporting date and calculating the capital that Sony would require to meet its contractual obligations to pay
 claims and expenses at a 99.5% confidence level for one year. The
cost-of-capital
rate represents the additional reward that investors require for exposure to the
non-financial
risk. The weighted average
cost-of-capital
rates of Sony for the fiscal year ended March 31, 2025 was 3.0%.
In addition, the risk adjustments determined by applying a cost of capital technique for the fiscal year ended March 31, 2025 correspond to the confidence level of 81.3% (time horizon: the life of the insurance contracts).

iv)
Discount rates
All cash flows are discounted using risk-free yield curves adjusted to reflect the characteristics of the cash flows and the liquidity of the insurance contracts. Sony determines the risk-free yield curves using the yields on government bonds. The yield curve is determined by incorporating long-term real interest rate and inflation expectations. Regarding extrapolation for the periods in which market data is not available, a method using an ultimate forward rate is applied. Specifically, Sony uses an ultimate forward rate of 3.5% and starts extrapolation in the 40th year (or the 30th year for U.S. dollar). The forward rates for the 41st year (or the 31st year for U.S. dollar) and onwards are extrapolated so that they will converge to the level of the ultimate forward rate in 30 years, using the Smith-Wilson method. To reflect the liquidity characteristics of the insurance contracts, the risk-free yield curves are adjusted by an illiquidity premium. Illiquidity premiums are determined by setting up a reference portfolio of Sony’s assets.
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.

v)
Investment components
Sony identifies the investment component of an insurance contract by determining the amount that it is required to repay to the policyholder in all circumstances, regardless of whether an insured event occurs or not. These include circumstances in which an insured event occurs, or the contract matures or is terminated without an insured event occurring. Investment components are excluded from insurance revenue and insurance service expenses.
 
vi)
Determination of coverage units
The amount of the CSM of a group of insurance contracts that is recognized as insurance revenue in each period is determined by identifying the coverage units in the group and recognizing in profit or loss the amount of the CSM allocated to
 
 
the coverage units provided during the current period. The number of coverage units is determined by considering for each contract the quantity of benefits provided and its expected coverage period. Specifically, Sony determines the quantity of benefits based on:
 
 
-
 
the death benefit amount in the case of contracts for which the death benefit amount increases or decreases based on the period (e.g., whole life, term life and variable life insurance contracts);
 
 
-
 
the premium amount proportionate to the insurance period in the case of contracts whose host contract and riders have different coverage types (e.g., disease and health insurance contracts); and
 
 
-
 
the cash surrender value (or the premium reserve during the annuity payment period) in the case of annuity contracts with investment-related services (e.g., individual variable annuity contracts).
Sony considers the characteristics of insurance contracts and aggregates the quantities of benefits related to insurance coverage, investment-return services and investment-related services when determining the relative weighting of the benefits provided to the policyholder by these services.
 
vii)
Claim development
Given that the actual amounts of claims do not materially differ from the undiscounted amounts of the claims previously estimated, information about claim development has not been disclosed for the fiscal year ended March 31, 2025.

Disclosure of transition to IFRS 17
IFRS 17 was effective for Sony as of April 1, 2023. Upon transition to IFRS 17 as of April 1, 2022, Sony determined that it would be impracticable to apply the full retrospective approach to certain groups of insurance contracts, as the necessary information was unavailable due to restrictions of contract data and systems in the past or it was impossible to recreate past estimation without the use of hindsight. Sony has applied alternative transition methods (the modified retrospective approach
 
 
or the fair value approach) to groups of insurance contracts for which the full retrospective approach is impracticable as of the date of the transition.
Sony has applied the following approaches on transition to IFRS 17:
 
Year of issue (fiscal year)
 
Transition approach
2015 and thereafter
 
For all groups of insurance contracts: Full retrospective approach
1993 – 2014
 
For groups of insurance contracts with direct participation features and certain groups of insurance contracts without direct participation features: Fair value approach
 
For other groups of insurance contracts: Modified retrospective approach
In and before 1992
 
For all groups of insurance contracts: Fair value approach
Modified retrospective approach
The objective of the modified retrospective approach was to achieve the closest outcome to retrospective application possible using reasonable and supportable information available without undue cost or effort. Sony has applied each of the following modifications only to the extent that it did not have reasonable and supportable information to apply IFRS 17 retrospectively.
Sony has applied the following modifications to certain groups of insurance contracts:
 
  -
for groups of contracts issued, initiated or acquired from April 1, 1993 to March 31, 2015, the future cash flows on initial recognition were estimated by adjusting the amount as of April 1, 2015, which can be determined retrospectively, for the cash flows that were known to have occurred before that date;
 
  -
for groups of contracts issued, initiated or acquired from April 1, 1993 to March 31, 2013, the illiquidity premiums applied to the observable risk-free yield curves on initial recognition were estimated by determining an average spread between the observable risk-free yield curves and the discount rates, which can be determined retrospectively, for the period from April 1, 2013 to March 31, 2022. The amount of insurance finance income or expenses recognized in accumulated other comprehensive income as of April 1, 2022 was calculated by using this discount rate; and
 
  -
the risk adjustment for
non-financial
risk on initial recognition was determined by adjusting the amount as of April 1, 2022 for the expected release of risk before that date.
After applying such modifications to fulfillment cash flows, the CSM (or the loss component) on initial recognition was determined as follows:
 
  -
the amount of the CSM recognized as profit or loss before April 1, 2022 was determined by comparing the remaining coverage units as of April 1, 2022 and the coverage units provided based on groups of insurance contracts before that date; and
 
  -
the amount allocated to the loss component before April 1, 2022 was determined using the proportion of the loss component relative to the total estimate of the present value of the future cash outflows plus the risk adjustment for
non-financial
risk on initial recognition.
Fair value approach
Under the fair value approach, the CSM (or the loss component) as of April 1, 2022 was determined as the difference between the fair value of a group of insurance contracts and the fulfillment cash flows at that date.
For all insurance contracts measured under the fair value approach, Sony used reasonable and supportable information available as of April 1, 2022 to determine the following matters:
 
 
-
how to identify groups of contracts;
 
 
-
whether a contract meets the definition of an insurance contract with direct participation features; and
 
 
-
how to identify discretionary cash flows for contracts without direct participation features.
For groups of contracts measured under the fair value approach, the discount rates on initial recognition were determined as of April 1, 2022 rather than at the date of initial recognition.
For all insurance contracts measured under the fair value approach, the amount of insurance finance income or expenses recognized in accumulated in other comprehensive income as of April 1, 2022 was determined to be zero.
The effects of transition to IFRS 17 on Sony’s consolidated financial statements are as follows. As a result of the execution of the Partial
Spin-off
of the Financial Services business, SFGI, which operates the Financial Services business, has been excluded from consolidation. Therefore, figures are presented only for the fiscal year ended March 31, 2025.

Insurance and market risks
As a result of the execution of the Partial
Spin-off
of the Financial Services business, SFGI, which operates the Financial Services business, has been excluded from consolidation. Therefore, each risk related to the Financial Services business is presented only as of March 31, 2025.
Risk management policy and exposure
In the life insurance business, Sony manages various market-related risks in the following manner:
 
(a)
Insurance risk management
Insurance risk
With respect to insurance underwriting risk, based on the level of policy reserves and capital levels, the life insurance subsidiary manages the insurance portfolio appropriately, such as setting policy limits for each type of insurance as necessary. In addition, underwriting standards for each product and standards for revision and abolishment are clearly defined as internal rules and are regularly reviewed.
Concentration of insurance risk
The insurance contract portfolio does not have an excessively concentrated insurance risk.
 
 
(b)
Market risk management
Interest rate risk management
Interest rate risk is managed by the risk management division of the life insurance subsidiary based on the policies for interest rate risk management that specify details such as risk management methods and procedures. Based on ALM policies that are determined through such methods as deliberation by the life insurance subsidiary’s Executive Committee, the subsidiary understands and confirms actual risk conditions with its Board of Directors. The division maintains an overall understanding of the interest rates and durations of financial instruments, monitors them based on the analysis of the quantity of risk using VaR, and periodically reports the status of each risk to the life insurance subsidiary’s Board of Directors and Executive Committee.
As part of the ALM management, the life insurance subsidiary invests in financial assets that match the characteristics of the insurance contract obligations, and thereby reduces interest rate risk as much as possible. Through the purchase and sale of financial assets included in their portfolio, the interest rate sensitivity (duration) of financial assets and insurance contract obligations is matched as much as possible so that they ensure sufficient cash flow to settle insurance claims as they come due.
Exchange rate risk management
Exchange rate risk is managed by the risk management division of the life insurance subsidiary based on the policies for exchange rate risk management that specify details such as risk management methods and procedures. The division periodically reports the status of each risk to the life insurance subsidiary’s Board of Directors and Executive Committee.
Equity market price fluctuation risk management
Equity market price fluctuation risk is managed by the risk management division of the life insurance subsidiary based on the policies for equity market price fluctuation risk management that specify details such as risk management methods and procedures. The division periodically reports the status of each risk to the life insurance subsidiary’s Board of Directors and Executive Committee.
Derivative transactions risk management
Derivative transactions are managed by the risk management division of the life insurance subsidiary based on the policies for derivative transactions that specify details such as risk management methods and procedures. The division periodically reports the status of each risk to the life insurance subsidiary’s Board of Directors and Executive Committee.

(a)
Risk management policy and exposure
In line with liquidity risk management policies, the accounting division of each insurance subsidiary prepares and updates cash flow plans in a timely manner based on the reports from departments and manages cash flows, and the risk management division of each insurance subsidiary manages the liquidity risk. The accounting division and risk management division periodically or as needed report such information to each insurance subsidiary’s Board of Directors and Executive Committee.
