UnitedHealth Group Incorporated occupied the top spot in AM Best’s ranking of the world’s 25 largest insurance companies for a fourth straight year, with $158.5 billion in net premiums written (NPW) in 2017. In addition, Allianz SE moved up two places to the No. 1 spot on AM Best’s ranking by 2017 non-banking assets, dislodging MetLife Inc., which fell to No. 5.

AM Best released the rankings of the world’s largest global insurance companies, by NPW and non-banking assets, in the Dec. 31, 2018, issue of BestWeek. The two rankings are based on BestLink data and additional research. Overall, the annual rankings found stability at the top, as four of the top five insurers by NPW and all five of the insurers by assets for 2017 remained from the previous year’s top five rankings. AXA S.A. was ranked at No. 2 in each of the latest rankings.

U.S.-based health insurance carriers and insurers in China continue to dominate the NPW ranking, accounting for six of the top 10 insurers. Ping An Insurance (Group) Company of China Ltd. jumped into the top five from No. 9 in the previous year, behind a 2017 year-over-year premium increase of 30%. China Life Insurance (Group) Company showed a 14% gain and People’s Insurance Company (Group) of China Ltd. gained 10%. Just outside the top 10, Berkshire Hathaway Inc. climbed to No. 11 from No. 16 as the company saw its premiums rise 33% in 2017. On the asset ranking, MetLife Inc.’s fall to No. 5 was precipitated by a hefty reserve charge in 2017, related to its group annuity business to compensate for unpaid benefits.

  1. UnitedHealth Group Incorporated, United States

  2. AXA S.A., France
