3 Critical Accounting Estimates and Judgements in Applying Accounting Policies

Certain reported amounts of assets and liabilities are subject to estimates and assumptions. Estimates and judgements by management are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

The sensitivity analysis with regard to insurance risk and market risk is set out in note 5.

Fair value of financial instruments

The fair value of financial instruments is determined based on quoted market prices, where available, or on estimates using present values or other valuation techniques. Those techniques are significantly affected by the assumptions used, including discount rates and estimates of future cash flows. Where market prices are not readily available, fair value is based either on estimates obtained from independent experts or quoted market prices of comparable instruments. In that regard, the derived fair value estimates cannot be substantiated by comparison with independent markets and, in many cases, could not be realised immediately.

The categorisation within the fair value hierarchy (i.e. level 1, 2 or 3) of the inputs to the fair value measurements of financial instruments carried at fair value is set out in note 33.

The principal methods and assumptions used by the Group in estimating the fair value of the following financial instruments are as follows:

Fair values for debt and equity securities are generally based upon quoted prices in active markets, if available. These inputs to the fair value measurement are generally categorised as level 1 within the fair value hierarchy. In inactive markets, information about prices from recent transactions with the same or similar instruments, quotes from brokers, indices and other input are taken into consideration in the determination of fair values. A market is deemed no longer active if prices available do not represent regularly occurring market transactions on an arm’s length basis. Furthermore, the volume of trading activity has declined significantly and bid/ask spreads have widened above a certain level.
   With regard to debt securities carried at fair value inputs to the fair value measurement categorised as level 2 within the fair value hierarchy are primarily determined using present value techniques on the basis of yield curves and appropriate spreads or discounted cash flow models with deposit and swap rates as the main input parameters. With regard to equity instruments carried at fair value inputs to the fair value measurement categorised as level 2 within the fair value hierarchy are determined using quotes from the custodian bank for the determination of fair values of fund units. Quoted prices of the underlying equity and debt securities are taken into account. Some fair value measurements of fund units categorised as level 2 are determined based on quoted prices/redemption prices with an adequate adjustment for illiquidity. Fair value measurements of equity securities categorised as level 3 within the fair value hierarchy are determined based on net asset value techniques with an adequate adjustment for illiquidity.
Fair value measurements for derivative financial instruments are obtained from quoted market prices (level 1) and/or valuation models (level 2) as appropriate. Quoted market prices are sourced from well-known price providers such as Bloomberg. Fair values for over-the-counter derivatives are established based on well established valuation models (Black Scholes, discounted cash flows). Market quotes of the input variables are generally used as the parameters for the models. Main inputs to the models are deposit/swap rates (for interest rate swaps), yield curves, inflation and retail price index (for inflation-linked swaps), realised and implied volatilities (for equity variance swaps), interest rates and price volatility of underlying (for total return swaps), foreign exchange spot rates and foreign exchange ticks (for foreign currency forwards). In certain cases these market quotes may be slightly adjusted to better reflect specific market behaviour, e.g. volatility smiles.
Private equity investments are primarily classified as available for sale and are measured at fair value. The fair values are based on generally accepted valuation techniques. Valuation techniques use a maximum of market inputs and include the use of comparable recent arm’s length transactions, discounted cash flow analysis and other valuation techniques commonly used by market participants. Because of the inherent valuation uncertainty, those estimated fair values may differ significantly from the values that would be used if a ready market for the financial assets existed, and those differences could be material. The responsibility for determining the fair values lies exclusively with the general partner in the partnership. In determining the fair value of fund investments, the partnership considers the funds as transparent holding vehicles. The fair values of the underlying investments are determined using the general partner valuation. These fair value measurements are generally categorised as level 3 within the fair value hierarchy.
The fair values of loans, which are carried at amortised cost, are estimated using discounted cash flows based upon the Group’s current lending rates for similar loans. For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values equal the carrying values.
The fair value of hedge funds is based on their quoted market prices, if available. If no quoted market price is available, valuation techniques are used that take into account the market value of the underlying assets, transaction prices and other information.
The fair value of financial reinsurance assets and liabilities, which are carried at amortised cost, is estimated using discounted cash flow calculations.
The fair value of borrowings, which are carried at amortised cost, is estimated using discounted cash flow calculations based upon the Group’s current borrowing rates for similar borrowings with remaining maturities consistent with the debt being valued. The fair value of hybrid debt is estimated based on a discounted cash flow approach, assuming guaranteed coupon payments until maturity or until the next call date for perpetual instruments. Swap rates plus a Swiss Life-specific spread are used for discounting.
The fair value of liabilities arising from insurance and investment contracts for the account and risk of the Swiss Life Group’s customers is calculated based on the valuation of the underlying assets.
The fair value of investment contracts without discretionary participation, which are carried at amortised cost, is estimated using discounted cash flow calculations based upon interest rates currently being offered for similar contracts with maturities consistent with those remaining for the contracts being valued. The fair values of deposits are equal to the amount payable on demand or the carrying amount. The carrying amounts of variable-rate deposits approximate their fair values at the reporting date.
The fair value of investment contracts, which are carried at fair value, is measured using market-consistent, risk-neutral economic option price models, i.e. Monte Carlo simulations based on scenarios of capital market variables (share price and interest rate indices, interest rates and foreign currency rates). These inputs to fair value measurements are generally categorised as level 2 within the fair value hierarchy.
It is impracticable to determine the fair value of investment contracts with discretionary participation features due to the lack of a reliable basis to measure such supplemental discretionary returns. IFRS 4 Insurance Contracts is silent on the measurement of the amounts identified as DPF.

Fair value of non-financial instruments

The fair value of investment property is based on current prices in an active market for properties of a similar nature, condition or location – suitably adjusted. Recent prices for similar properties on less active markets, with suitable adjustments for differences, are also used for the estimation of the fair values. Furthermore, investment property is valued using discounted cash flow projections if reliable estimates and reasonable assumptions (such as rental income and operating expenses) can be made, based on external evidence. Future expenditure that will improve the property is not included in the fair value. The risk-adjusted discount rates used in the cash flow projections reflect the specific nature and location of the individual properties. The cash flows used in the projections are based on actual rental income on a sustainable basis. Cost is reflected in the cash flows based on experience and budgets approved by management. The cash flows include inflation. External valuations for individual real estate assets are performed on a rotating basis, but at a minimum each property is evaluated every three years.

Impairment of held-to-maturity and available-for-sale debt instruments and loans

and receivables

As a Group policy, held-to-maturity and available-for-sale debt securities and loans and receivables are assessed for impairment when a significant decrease in market value related to credit risk arises, namely after a downgrade of a debtor’s rating below single B– after initial recognition (i.e. CCC or lower according to Standard and Poor’s or equivalent) or when payments of principal and/or interest are overdue by more than 90 days.

Impairment of available-for-sale equity instruments

At each balance sheet date, an assessment is made whether there is objective evidence that an available-for-sale equity instrument is impaired. A significant or prolonged decline in the fair value of the security below its cost is considered objective evidence of impairment. In this respect, a decline of 30% or more is regarded as significant, and a period of 12 months or longer is considered to be prolonged.

Insurance liabilities

Past experience, adjusted for the effect of current developments and probable trends, is assumed to be an appropriate basis for predicting future events. Actuarial estimates for incurred but not reported losses are continually reviewed and updated and adjustments resulting from this review are reflected in income.

Insurance liabilities are established by using appropriate estimates and assumptions on mortality, morbidity, exercise of policyholder options and investment returns. With regard to mortality for example these estimates are typically based on standard industry tables. Management makes allowance for expected improvements due to continued advances in medical science and social conditions.

For insurance contracts and investment contracts with discretionary participation features with fixed and guaranteed terms, the definition of estimates occurs in two stages. At inception of the contract, estimates of future deaths, surrender, exercise of policyholder options, investment returns and administrative expenses are made and form the assumptions used for calculating the liabilities during the life of the contract. A margin for risk and uncertainty (adverse deviation) is added to these assumptions. These assumptions are “locked-in” for the duration of the contract. Subsequently, new estimates are made each year in order to determine whether the values of the liabilities so established are adequate in the light of these latest estimates. If the valuation of the liabilities is deemed adequate the assumptions are not altered. However, if the valuation of the liabilities is deemed inadequate, the assumptions underlying the valuation of the liabilities are altered (“unlocked”) to reflect the latest estimates; no margin is added to the assumptions in this event.

For insurance contracts and investment contracts with discretionary participation features without fixed and guaranteed terms, future premiums can be increased in line with experience. The assumptions used to determine the liabilities do not contain margins and are not locked-in but are updated at each reporting date to reflect the latest estimates.

Mortality and longevity — Pricing and valuation assumptions for mortality and longevity are generally based on the statistics provided by national insurance associations and complemented with internal claims experience reflecting own company records.

In Switzerland, mortality tables are usually reviewed every five years when new statistics from the Swiss Insurance Association become available. The tables are updated for significant changes.

Morbidity and disability — For the individual and group life business in Switzerland internal tables are in place. In the individual life business, the internal disability rates are based on the Swiss Insurance Association statistics and reflect the average situation of the past in the Swiss market. In the individual life business, only reactivation is considered, whereas increased mortality is also taken into account in group life business. In the individual life business, disability tables are usually reviewed every five years when new statistics from the Swiss Insurance Association become available.

In the group life business, tariffs can be adjusted due to loss experience with regard to disability each year. In the group life business, the tables are based on own company records reflecting loss experience. Especially in the group life business changes in the labour market may have a significant influence on disability. The tables are updated for significant changes.

In other markets, standard industry disability tables, national statistics and own company records are applied. Standard valuation pricing principles are typically validated against the client-specific disability experience.

Policyholder options — Policyholders are typically offered products which include options such as the right to terminate the contract early or to convert the accumulated funds into a life annuity at maturity. In case of early termination the policyholder receives a specified surrender value or a value which varies in response to the change in financial variables such as an equity price or an index. In the case of the conversion option, the policyholder has the right to convert an assured sum into a fixed life annuity. The option values typically depend on both biometric assumptions and market variables such as interest rates or the value of the assets backing the liabilities. In certain countries and markets policyholder behavioural assumptions are based on own company records. The assumptions vary by product type and policy duration.

Expenses and inflation — In Switzerland, expenses are taken into account in the pricing of the contracts using internal statistics. Such calculated amounts are allocated to the different lines of business. Inflation is reflected in these calculations.

In certain markets, expense allocation is based on an activity-based cost methodology. Recurrent costs are subdivided into the following main cost categories: acquisition costs, administration costs and asset management costs.

Investment returns — Assumptions relating to investment returns are based on the strategic asset allocation. From this gross investment return, projected asset management fees are deducted to obtain a net investment return.

The interest rates used in actuarial formulae to determine the present value of future benefits and contributions caused by an insurance contract are called technical interest rates. The technical interest rates have to be approved by the regulator. In certain countries, the insurance liabilities are based on the technical interest rates.

Impairment of goodwill

Goodwill is tested for impairment annually (in autumn), or more frequently if events or changes in circumstances indicate that goodwill might be impaired. The recoverable amounts of the business relating to the goodwill have been determined based on value-in-use calculations. These calculations require the use of estimates which are set out in note 18.

Defined benefit liabilities

The Swiss Life Group uses certain assumptions relating to the calculation of the defined benefit liabilities. These assumptions comprise the expected return on plan assets as well as future salary increases and future pension increases which have been derived from estimates based on past experience. The expected return on the plan assets takes into consideration the investment policy relating to the assets and their projected returns.

The assumptions are set out in note 24.

Income taxes

Deferred tax assets are recognised for unused tax-loss carryforwards and unused tax credits to the extent that realisation of the related tax benefit is probable. The assessment of the probability with regard to the realisation of the tax benefit involves assumptions based on the history of the entity and budgeted data for the future.


The recognition of provisions involves assumptions about the probability, amount and timing of an outflow of resources embodying economic benefits. A provision is recognised to the extent that an outflow of resources embodying economic benefits is probable and a reliable estimate can be made.
