BNY Mellon has won a new mandate to provide back-office services for Rainier Investment Management, Inc., a Seattle-based asset management firm with more than USD18bn in assets under management. BNY Mellon will provide a range of outsourcing support, including accounting, performance measurement, account opening, account reconciliation, client reporting and client billing."Strategically, outsourcing was the right choice for Rainier," said Melodie Zakaluk, chief operations officer of Rainier Investment Management. "It allowed Rainier to focus on outstanding client service while leveraging a scalable operational platform. All of the resources in the operations area prior to outsourcing have been reassigned to roles focused on servicing our clients. Our clients look to us for superior value, and we're confident that BNY Mellon is a partner we can rely on to help us consistently deliver."
