In a simulated stochastic model, the simulated losses can be made to "pass through" the layer and the resulting losses assessed appropriately. A stochastic investment model tries to forecast how returns and prices on different assets or asset classes, (e. g. equities or bonds) vary over time. The models and underlying parameters are chosen so that they fit historical economic data, and are expected to produce meaningful future projections. This idea is seen again when one considers percentiles (see percentile).

For example, in application, applying the best estimate (defined as the mean) of investment returns to discount a set of cash flows will not necessarily give the same result as assessing the best estimate to the discounted cash flows. The latter method is used in some of the most popular adviser tools such as Truth, Cash Calc and Voyant and is considerably less complicated, although these three use stochastic modelling in some of their features. The claims arising from policies or portfolios that the company has written can also be modelled using stochastic methods. 0000033078 00000 n Rory Percival, a consultant and former Financial Conduct Authority (FCA) technical specialist, explained stochastic tools better reflected the variation in possible returns in theory but could prove too complicated for some clients to understand in practice, when simpler tools may be more appropriate. The model can be regarded as an extension to that originally proposed by Trowbridge (1952). The relative uniqueness of the policy portfolios written by a company in the general insurance sector means that claims models are typically tailor-made. Stochastic cashflow modeling has emerged as the more popular choice for determining whether a client will run out of money in retirement, despite not being used by widely available adviser software. But there was an overwhelming feeling either tool was only suited to help set client expectations and their output was of very little value without a conversation around risk capacity, the Lang Cat found. This is especially important in the general insurance sector, where the claim severities can have high uncertainties.

The ideas were first developed for the Maturity Guarantees Working Party (MGWP) whose report was published in 1980. “Deterministic is easier to understand and hence may be more appropriate for some clients. For instance, applying a non-proportional reinsurance layer to the best estimate losses will not necessarily give us the best estimate of the losses after the reinsurance layer.
