June 3 - (The Insurer) - Lexington Insurance Company vice president and head of alternative risk property Jill McTiernan is leaving the AIG-owned wholesale platform to join Ryan Specialty Underwriting Managers (RSUM).

Wholesaler sources with knowledge of the situation said that McTiernan is making the move from the carrier to Ryan Specialty's MGU platform, although it could not be immediately confirmed what her new position will be.

In her role as head of alternative risk property at Lexington, McTiernan was involved in relationships with large complex risk-focused MGUs and MGAs such as Arrowhead and AmRisc, said the sources.

The executive was most recently based at Lexington’s Boston, Massachusetts office and spent just over 10 years at the insurer.

She was previously vice president and head of underwriting operations for programs at XL Group, before which she spent another 10 years at Lexington, latterly as assistant vice president for operations working on property risk management.

AIG and RSUM both declined to comment on this article.
