U.S. insurer American International Group Inc (AIG.N) has paused its plan for an initial public offering of Chartis Inc, its global property-casualty division, Bloomberg reported.

AIG chief executive Robert Benmosche told employees he considered the unit a core holding, the news agency said, citing two people familiar with the matter.

Chartis employs about 34,000 around the world and, with a net worth of about $40 billion, is one of AIG's largest divisions.

AIG was not available to comment.
