Munich Re is the largest IFRS 17 reporting reinsurer, but Swiss Re is top of the list as the largest non-IFRS 17 reporting reinsurer, according to rating agency AM Best.
The rating agency released its list of top 50 reinsurers for 2023, which was largely the same at the top end of the scale, except for the addition of IFRS 17-compliant insurers which introduced a layer of complication to the annual analysis.
Top of the IFRS list were Munich Re, Hannover and Scor while local GAAP leaders were Swiss Re, Berkshire Hathaway and Lloyd's.
AM Best said the transition to IFRS 17 had diminished the comparability among reinsurers but things should normalise a bit more next year. Swiss Re, for one, has migrated to IFRS reporting from the start of this year.
Under the old IFRS 4 accounting method, re/insurers reported information about premiums written and earned, which was generally comparable with US GAAP reporting peers. Under IFRS 17, re/insurers report information about insurance revenue, which is composed of different components from premium written and earned in IFRS 4.
"Although the new standard impacts only 15 of the companies included in the list in 2023, the change from IFRS 4 to IFRS 17 has added complexity to financial performance comparison amongst all reinsurers," AM Best said.
AM Best said the global reinsurance industry is in the midst of a "generational hard market" that has driven the significant growth for many reinsurers in the last year.
The hard market conditions were reignited by hurricane Ian and substantial secondary peril events in 2022 and significant rate increases as well as a tightening of terms and conditions continued through the 2023 renewals. Added to these, mark-to-market unrealised fixed-income investment losses, loss cost and social inflation, and global macroeconomic uncertainty caused a substantial imbalance in reinsurance supply and demand dynamics. In aggregate, these factors resulted in significant growth in premium volume, underwriting income and net income.
