Q

Describe the traditional discounted cashflow method of valuing assets and liabilites

A

Both assets and liabilities are valued by discounting the future cashflows using a rate that reflects the long-term future investment return expected.

Q

What is the major criticism of the traditional discounted cashflow method of valuing assets and liabilities?

A

It provides a value of the assets that is different from the market value, which introduces an additional element of risk. It is also difficult to explain to clients.

(Consequently, there has been a move towards market-related methods of valuing assets and liabilities)

Q

Give two definitions of “fair value”

A
  1. The amount for which an asset could be exchanged or a liability settled between knowledgeable, willing parties in an arm’s length (act independently without one party influencing the other) transaction.
  2. The amount that the enterprise would have to pay a third party to take over the liability

Q

Give 2 examples of financial contracts for which it might be fairly straightforward to determine a fair value.

A
  1. Unit linked contracts - the value of the liability is effectively known since it is the value of the units and the unit price is determined on a frequent basis.
  2. The pensions in payment liabilities of a benefit scheme - there may be an active ‘buyout’ market consisting of insurance companies and other financial organizations that are prepared to provide immediate annuities to cover pensions in payment.

Q

What is the major difficulty in determining the fair value of a provider’s liabilities?

A

There is no liquid secondary market in most of the liabilities that actuaries are required to value, so the identification of fair amounts from the market is not practical. As a result, fair values of liabilities need to be “estimated” using market-based assumptions.

Q

Describe the replicating portfolio - mark to market method of valuing assets and liabilties

A

Assets are taken at market value.

Liabilities are discounted at the yields on investments that closely replicate the duration and risk characteristics of the liabilities - often bonds. The replicating portfolio can be determined using stochastic optimization techniques (asset-liability modelling)

The bond yield may be based on government or corporate bonds - the latter will alow for credit risk

Ideally, term-specific discount rates would be used to reflect the shape of the yield curve.

Other assumptions should also be market related, for example the market rate of inflation is derived as the difference between the yields on fixed interest and index-lined government bonds of an appropriate term.

Q

Describe the replicating portfolio - bond yields plus risk premium method of valuing assets and liabilities

A

The method is similar to the mark to market method with assets taken at market value and the liabilities discounted at the yields on investments that closely replicate the duration and risk characteristics of the liabilities- often bonds.

However, the liability discount rate is adjusted to reflect a equity risk premium.

The equity risk premium may be constant or variable.

The school of thought is that taking account of the extra return from other assets is unsound unless account is also taken of the extra risk. Some actuaries argue that liabilities should only be valued using a risk-free rate of return (ie government bond yields)

Q

Describe the asset-based discount rate approach for valuing assets and liabilities

A

Assets are taken at market value.

An implied market discount rate is determined for each asset class. eg for fixed interest securities it may be the GRY, for equities it involves estimating the discount rate implied by the current market price and the expected dividend and/or sale proceeds

The liabilities are valued using a discount rate calculated as the weighted average of the individual discount rates based on the proportions invested in each asset class.

The discount rate could be determined using the distribution of the actual investment portfolio or the scheme’s strategic benchmark (if the current asset allocation is not representative of the scheme’s usual investment strategy)

Q

Outline how the fair value of liabilities can be determined by performing a “risk-neutral” market-consistent valuation.

A

The value is determined as the present value of future liability cashflows, discounted at the pre-tax market yield on risk-free assets.

Such assets might be swaps (in the UK) or government bonds.

Q

Outline the factors to consider when valuing guarantees

A
  1. In general, a cautious approach is taken
  2. However, unless all guarantees are in the money, assuming the worst case scenario in every case will build in too much caution.
  3. A stochastic model should be used for valuing guarantees, to show the likelihood of the guarantees biting and the associated cost. Parameter values should reflect the purpose for which the results are required.
  4. Guarantees may become more or less onerous over time.
  5. The value of guarantees and their influences on consumer behavior will vary widely according to the economic scenarios and the sophistication of the market.

Q

Outline the factors to consider when assessing the cost of an option from the perspective of the provider

A
  1. In general, a cautious approach is taken
  2. However, this can build in too much caution.
  3. For example, a policyholder may not exercise the highest cost option despite it being financially better for them to do so.
  4. It is necessary to allow for anti-selection risk when valuing options, or to mitigate this risk using eligibility criteria for exercising the option.
  5. Options and guarantees are not necessarily independent; some guarantees may make options more valuable in certain circumstances.
  6. Deterministic and closed form (e.g. Black Scholes) methods could be used

Q

The assumptions used when valuing options will depend on…

A
  1. The state of the economy (must be scenario spesific)
  2. Demographic factors, e.g. age, health, employment status
  3. Cultural bias
  4. Consumer sophistication

Q

State 2 examples of where an assumption of the policyholders always exercising an option that is in-the-money from the provider’s perspective may not be appropriate

A
  1. The attraction of cash - The option’s holder may be influenced by the options that is immediately financially advantageous, rather than an option that may be of greater value, but where the benefit is realised in the future - such as taking a pension in cash rather than as an annuity
  2. Tax benefit - The policyholder receives beneficial tax treatment on the alternative benefit - sum as taking part of a pension as a tax-free lump sum

Q

Describe 3 approaches to allowing for risk in a traditional discounted cashflow valuation

A
  1. Best estimate and margin - a margin is explicitly built into each assumption. The size of the margin reflects the amount of risk involved and its materiality to the final result.
  2. Contingency loading - the liabilities are increased by a certain percentage. The size of the margin reflects the uncertainty involved. This method is very arbitrary.
  3. Discount rate - Cashflows are assessed on a best estimate basis, and then discounted at a rate of return that reflects the overall risk of the project or liability. In order to allow for prudence in a liability valuation, the discount rate should be reduced
17
Q

Outline how risk can be allowed for in a market-consistent or fair valuation of liabilities

A

Financial risk - allowed for in a market-consistent manner by using a replicating portfolio or stochastic modelling approach. Mismatching risk is typically ignored, as the fair value of the liabilities should be independent of the assets held.

Non-financial risk - allowed for by adjusting the expected cashflows or by adjusting the discount rate. Alternatively, an extra provision or capital requirement can be held, such as using a risk margin. Adjustments depend on the amount of the risk and the costs of the risk implied by market risk preferences.

Q

Outline 4 methods that an insurance company might use for establishing provisions, particularly a general insurance company.

A
  1. Statistical analysis - used where many claims following a known pattern. The provision could be set equal to the amount that keeps the probability of ruin below a certain level.
  2. Case-by-case estimates - used if the insured risk is rare or there is large variability in the outcome such as for personal injury claims.
  3. Proportionate approach - used for risks that have been accepted but for which the risk event has not yet occurred. Provision is a proportion of the part of the premium designed to cover claims. The proportion will represent the unexpired period of cover (for example 25% expected to cover expenses, commissions and profit, and the 75% covers risk. A provision of 75% can be set for the unexpired duration) - probeer om nog beter te verstaan - ek dink dit moet unexpired period of risk wees - check
  4. Equalization reserves - Establish reserve in years when no claim arises, with the view of using the reserve to smooth profits when a claim does occur. May not be recognized by the regulator, and can be perceived by the tax authorities as a way of deferring profit and thus tax.
