Citi Investor Services Wins US$380 Billion Middle Office Mandate from Aegon Asset Management
Citi Investor Services has been awarded a full middle office mandate by Aegon Asset Management (Aegon AM), covering US$380 billion in Assets under Management and extending a long-term relationship with a key client of 20 years. This mandate expands the scope of services already provided to Aegon AM by Citi, including custody, depositary, collateral, fund accounting and administration as well as transfer agency services.
Citi has extended the breadth of its middle office offering to include full Investment Book of Record (IBOR) services, trade management and settlement and performance measurement via Aladdin Accounting services. This transition marks a significant milestone in Citi’s growing presence as an integrated service provider on BlackRock’s Aladdin investment platform. It expands Citi’s Aladdin Provider model, both in scale and sophistication, with Investor Services now delivering an enhanced suite of services that includes full middle office, enhanced data management services and accounting and performance services.
Supporting these enhanced capabilities, Aegon AM’s Operations employees based in Budapest, Hungary have joined Citi Investor Services. These individuals are based at the bank’s Citi Solutions Centre in Budapest, where they will continue to grow their careers in roles of comparable scope and responsibility and bring their valuable expertise to the Investor Services team.
The Citi Solutions Centre in Budapest is part of a global network of technology and operations hubs for Citi’s Investor Services business. In addition to Budapest, teams in India, Poland, the U.K., and the U.S. also support Citi’s Aladdin Provider model for Aegon AM’s entities in the U.K., U.S., and Netherlands.
“This mandate significantly expands our relationship with Aegon AM and exemplifies our strategy to accelerate growth with asset managers globally by providing world class middle office services and technology,” said Mike Hughes, Head of Fund Services at Citi Investor Services. “We warmly welcome our new colleagues to Citi as we build scale on Aladdin to support the world’s largest and most complex asset managers, win new clients, and continue growing our business.”
Mike Tumilty, Global Chief Operating Officer at Aegon AM, said, “We are delighted to expand our longstanding partnership with Citi by leveraging their middle office services on our Aladdin platform. Following our successful implementation of Aladdin, working with Citi to operate our middle office on the Aladdin instance was a clear next step in our evolution towards a global, scalable, and efficient operating model. Our team in Budapest were integral to this journey, and we are pleased that they continue to support us, now as a client, while developing their careers with Citi.”
