Alexander Forbes has lost a team of major risks brokers to BMS.
BMS is taking on a team of eight, to be added to its existing direct and facultative team of five. They will concentrate on global accounts typically with multi-location property risks.
They will be under the management of Steve Higginson, chairman and managing director of BMS International.
Higginson said: "They have an excellent reputation in the market and I've worked with them very closely for the last 18 months.
"They bring a skill set to augment our existing capability in an area we have targeted for strategic development."
The team will work on predominantly property risks requiring layered structures, quota share deals or placements through captives for big regional or multi-national companies.
Its target sectors are likely to include petro-chemicals, oil and gas, minerals and mining and financial groups.
The departure to BMS follows that of a US binding authority team which left earlier this year, to be split between THB and Bowood.
THB Group gained a team of eight, headed by Roy Nadal, to work on US binding authority business.
The team works with brokers and agents in North America on risks that fall outside the criteria set by much of the domestic market and will grow the group's geographical spread as well as increasing its service standards and product lines.
Bowood is also adding to existing capabilities, with lead brokers Paul Fagg, who starts this month, and Colin Loftus being complemented by another two behind them.
