Pershing has expanded its presence at Liverpool's iconic Royal Liver Building after signing a 10-year lease for the entire eighth floor.
CBRE brokered the 28,000 sq ft letting to the Bank of New York Mellon subsidiary on behalf of the building's owner, Royal London.
Pershing, which already had a smaller base at the Royal Liver Building, was established in London in 1987.
It provides operational, IT, regulatory and investment support for private client firms and institutional broker dealers across Europe.
CBRE director Mark Worthington said: "Pershing previously occupied a smaller suite within Royal Liver Building but was looking to expand and after an extensive search of the market.
"We are all delighted that they have chosen to relocate and expand in the building. The building has been very successful in attracting and retaining occupiers due to the quality of the space provided and the flexible and commercial approach adopted by the building owners, Royal London."
Richard Wharton of Jones Lang LaSalle acted for Pershing.
He said: "Pershing is delighted to continue its relationship in Liverpool with Royal London.
"The quality of the refurbishment within this internationally recognised landmark office building meant that Pershing's occupational requirements were met without having to relocate elsewhere, causing minimal disruption to their operation in Liverpool.
"This expansion will help enhance Pershing's client services and provide a superior working environment for their staff and they look forward to a mutually beneficial future within the Royal Liver Building."
