(Reuters) - JPMorgan Chase ( JPM ) has expanded the roles of some executives in its sales department, the bank said in an internal memo seen by Reuters on Tuesday.

Matthieu Wiltz will become the sole head of credit, securitized products group and public finance sales. He was previously the co-head of the business alongside Howard Rothberg, who is leaving after nearly 21 years at the bank.

Adam Englander has been named the head of cash equities, prime financial services, capital advisory and data and analytics sales, the memo said, while Brad Tully will lead the corporate and private side unit.

All the executives will report to Scott Hamilton and Claudia Jury, who were named the bank's global co-heads of sales and research last month.

The developments were first reported by Bloomberg News.
