Liberty Specialty Markets has rebranded its reinsurance division as Liberty Mutual Re, effective immediately.

The rebranded business will underwrite risks related to property, casualty and specialty businesses.

Liberty also launched reinsurance operations in Italy, with offices in Rome and Milan. The Italian operations are headed by Massimiliano Fantini, who was most recently country manager for Guy Carpenter & Co. LLC in Italy.

Liberty Mutual Re's U.S. operation has begun writing marine risks for the first time, headed by Scott Johnson.

Johnson, who joins from Munich Re Co., will report to James D'Onofrio, Liberty Mutual Re's general manager for the U.S.
