Seven years after US investment bank Jefferies made a string of “key appointments” to grow its international mortgage and asset-based securities group, the firm has parted ways with one of the most senior of those recruits.

Steven Hulett, who was co-head of European MBS/ABS, has left the bank, according to a filing with the UK's Financial Services Register and people familiar with the situation. His departure means that of the eight "strategic hires" announced in August 2009, half have since left.
