JP Morgan has stormed to the top of a league table measuring fees earned from German conglomerate Siemens after advising on its $7bn (€5.1bn) acquisition of laboratory diagnostics company Dade Behring, the largest takeover by a German company in the US this year.

Siemens' purchase of Dade Behring in an all-cash deal, takes JP Morgan's deal credit from the company to nearly $13bn and its fee income to over $30m. The purchase came as Siemens sold its auto business, VDO Automotive, to Continental for €11.4bn. It is the US bank's third deal from the German company this year.
