What's the deal? BP Marsh-backed Australian underwriting agency ATC Insurance Solutions has acquired Frontier Global UnderwritingDealroom has a profile for this one. Try Dealroom →, a specialty financial lines managing general agent (MGA) and London market wholesale broking group.

The deal gives ATC an expanded footprint in London and deeper capabilities in financial lines — a fast-growing segment of the specialty insurance market.
