Dhimant Shah, credit derivatives trader at ABN AMRO in Singapore, recently resigned, according to officials at the firm. He reported to Arne Groes, global head of credit markets trading in London. Shah's whereabouts could not be determined by press time. Groes did not return calls. Shah moved to trading from the credit structuring side earlier this year as part of a restructuring effort following the departure of two senior staff to UBS (DW, 5/27).
