These days international insurers are spending a lot of time focusing on a significant accounting change, best known by its abbreviation, IFRS17.
IFRS 17 – International Financial Reporting Standard 17 – is an accounting rule scheduled to take effect in 2021. It is designed to bring more clarity to insurance financial statements. It affects most insurers that operate internationally; US-only insurers conform to generally accepted accounting principles (GAAP) or statutory accounting principles, or both.
Life insurers will be affected much more than property/casualty insurers.
