Contracts They are EITHER pure endowments (10,000 after 15 years) OR annuities (1,000 per annum for 15 years at end of year), with all payments certain.

Pricing Approach This can be either market-related (“MtM”) or off-market (“Off”).
Assets Portfolios There are now 3 different investment options (ILGs excluded).
Random Experiences There are now four (instead of six to end-2019).
Random Scenarios The model is run 1,000 (instead of 2,000 for end-2021) times using random numbers which differ over time for each variable.
Expected Returns Separately for each experience, for the “Off” case, the approach is one multiple for equities and another for conventional bonds .
Surpluses And Deficits No correction payments are made during the 15 years.
Single Premium This is determined by the initial pricing approach.
