IFRS 17 and the reporting reset
The standard changed how insurance revenue is recognised and measured. The harder part for most finance functions was never the accounting — it was assembling data at the grain the standard assumes.

IFRS 17 replaced a patchwork of local practices with a single measurement model for insurance contracts. Its effect on the finance function has been structural: contracts are grouped, measured and disclosed in ways that most legacy policy systems were never designed to support.
Grouping is a data problem
The standard expects contracts to be grouped by portfolio, profitability and issue period. That is straightforward to describe and awkward to produce when policy records lack the attributes the grouping depends on, or when those attributes were captured inconsistently over the years being restated.
Actuarial and finance on one timeline
Measurement pulls cash-flow projections, discount rates and risk adjustment into the reporting cycle itself. Where those inputs arrive as spreadsheets late in the close, the cycle stretches. Where they are produced from the same system of record as the underlying contracts, it compresses.
Disclosure is the forcing function
Movement analysis has to explain how balances changed over the period, component by component. That requirement tends to expose whichever parts of the estimation chain were previously carried by judgement in a spreadsheet rather than by a repeatable calculation.
