Hi - I think perhaps what Emma meant to suggest was to replace the references to Old UK GAAP with IFRS throughout the main body of the question, and then leave question parts (ii) and (iii) unchanged from how they appear in the paper - ie they can continue to refer to IFRS generally. I personally don't think that having these two question parts referring to just IFRS 17 would work, because it only applies to one of the two products.
So part (ii) continues to be about splitting between insurance and investment products - and the solution still holds true, except that it would now likely also refer to moving towards using IFRS 17 for the insurance product, rather than only referring to IFRS 4. [The classification approach to split between insurance vs investment products once IFRS 17 comes into force is as it is under IFRS 4 now.]
The term assurances would be classified as insurance contracts, and so be subject to IFRS 4 at present, soon to be replaced by IFRS 17. The UL bonds would be classified as investment contracts, and so be valued under IFRS 9 (or IAS 39) and IAS 18.
And part (iii) would now require us to compare the UL valuation approach as is currently described in the solution (under IAS 18 and IFRS 9 / IAS 39) with the IFRS 17 approach that would apply to the term assurances, ie the BBA. So this solution would need to be adjusted in terms of the latter.
In this scenario, the UL contracts wouldn't be subject to the VFA because they wouldn't be classified as insurance contracts (the death benefit isn't high enough) - and remember that IFRS 17 only applies to insurance contracts.
However, there could well be another scenario arising in a question that could ask for a comparison between the BBA and VFA approaches.
Hope that helps to clear this up.
