Jan Straatman, the global investment chief for Lombard Odier Investment Managers, plans to retire at year-end, Lombard Odier said in a statement on Monday.

His duties will be successively transferred to the respective investment chiefs of the bank's boutiques, with the London-based Straatman remaining as an advisor as well as a board member of its fund company. 

The investment expert joined Lombard Odier five years ago to reinforce its asset management arm,  which he did by building up a multi-boutique structure. Previously, Straatman was investment chief for ING Investment Managers.
