I'm sure that a model solution will be provided on the IFoA website eventually. In the meantime here's a way to start the project.
The Additional Guidance gives the full picture; starting with \(E(x)\) and progressing through to the total initial amounts exposed to risk \(E^{a^{*}}(x)\). These are the values given in the Exposure worksheet.
The expected claims are then equal to these total initial amounts exposed to risk multiplied by the probability of a claim occurring within each age band. The slight complication here is that the exposure data is split by age band, and the mortality table is split by age.
