As financial instruments traded in the market, credit default swaps may be subject to a high degree of volatility. This volatility may affect the reliability of credit default swaps as proxies to measure the credit risk associated to a particular investment in isolation, since the credit default spreads may reflect not only the risk of default but also other non-related factors such as the liquidity of the credit default swaps contracts or the volume of contracts negotiated. Those circumstances could lead to situations where, for instance, the same instrument may have different credit default swaps spreads ...

It should be recognised in determining and evaluating discount rates that in some instances, particularly those associated with the valuation of intangibles still in development, intangibles may be among the most risky components of a taxpayer’s business. It should also be recognised that some businesses are inherently more risky than others and some cash flow streams are inherently more volatile than others. For example, the likelihood that a projected level of research and development expense will be incurred may be higher than the likelihood that a projected level of revenues will ultimately be generated. The discount rate or rates should reflect the level of risk in the overall business and the expected volatility of the various projected cash flows under the circumstances of each individual case ...

When applying valuation techniques, including valuation techniques based on projected cash flows, it is important to recognise that the estimates of value based on such techniques can be volatile. Small changes in one or another of the assumptions underlying the valuation model or in one or more of the valuation parameters can lead to large differences in the intangible value the model produces. A small percentage change in the discount rate, a small percentage change in the growth rates assumed in producing financial projections, or a small change in the assumptions regarding the useful life of the intangible can each have a profound effect on the ultimate valuation. Moreover, this volatility is often compounded when changes are made simultaneously to two or more valuation assumptions or parameters ...
