Many areas of the operating model will be affected by the incoming standards. These are illustrated above in our generic TOM for an insurance close. The boxes in green being the areas of the close that will be affected by the standard and are likely to need to change.  The red lines show the greatest challenges to data-flow. Every time a step in the operating model changes, there will be impacts on its input requirements and the outputs to the next step.  Operationally, major impacts will be seen:

• Policy administration systems (PASs) will have to supply additional data, some of which may be of a type not yet recorded.
• An accounting solution will have to be put in place. This will be especially challenging for companies who do not currently report in both EU and US.
•  Valuation models will become more complex, with perhaps 30 to 60 times more effort to complete. Consequentially, prevailing models will become cumbersome – especially those who rely on model libraries.
•  Audit of actuarial models will by external auditors will now happen because they will become part of the IFRS close. Models will somehow need to engineered to be measurable by external auditors. Manual interventions will be harder to justify.
•  Ledgers and sub-ledgers will contain additional information, this will be compounded if an insurer chooses an accounting solution that relies on actuarial models for inputs.
• Increased disclosures by the accounting teams will put pressure on operational close activities.
• Volume of data will snowball. Old systems may crack under the pressure of requirements they weren’t designed to deliver. Manual transfer of information will become more difficult.

The consequence of these requirements is that everything is going to be much more complicated, systems that have limited capability, inefficient modelling methods and manual interventions might force the need to change an insurers operating model. Some insurers may wish to use IFRS 17 as an opportunity to be more radical and change the governance of how accounting and actuarial closes are completed. These could include level of devolution of accounting and actuarial work between branches, subsidiaries and group head offices. It might also include major systems changes or upgrades. However, every time a change to the operating model of an insurance close is identified, then the greater the risk that the required operations will not be ready in time for first comparative in 2022 or even the actual close in 2023. In some respects, the operating model of insurers shouldn’t need to change significantly, however key areas of the process will be affected.
