Janus Capital Corp.'s offshore assets under management jumped 206% in the first quarter, to $5.5 billion.

The assets include $3.4 billion in the Janus World Funds, said Richard Garland, chief executive of Janus International, who attributed the growth partly to three new offshore funds and new subadvisory agreements.

Janus, of Denver, has hired a regional sales director for Hong Kong and plans to hire wholesalers for the Hong Kong area by July, Mr. Garland said. The fund giant is also beefing up its 10-person office in London. Mr. Garland said he expects to add three to five employees this year, including someone to cover Southern Europe.

Janus led the industry with $28.2 billion of U.S. net sales in the quarter, according to Financial Research Corp. in Boston. Putnam Investments ranked second with $7.8 billion.
