Founded as an actuarial firm in New York City in 1916 by George B. Buck Sr.,[3] in 2016 the firm had more than 1,500 employees and affiliates in nearly 200 global locations.
Buck Consultants remained an independent organization until 1997 when it was acquired by Mellon Financial.[4] The Buck Consultants brand name was scrapped in late 2003 when Mellon unified various business lines under the name Mellon Human Resource & Investor Solutions (Mellon HR&IS).[5]
Affiliated Computer Services (ACS) acquired Mellon's human resource businesses in 2005[6] and reintroduced the Buck Consultants brand. In 2010, Xerox acquired ACS for $6.4 billion. Buck Consultants was later rebranded as "Buck Consultants at Xerox".[7]
At the beginning of 2017, Conduent was spun off from Xerox. Buck Consultants, which was one of the businesses spun off, was renamed Conduent HR Services.[8]
In May 2018, Conduent announced that it would sell the Buck Consultants portion of its business to H.I.G. Capital, starting the clock on a 90-day transition period in which it hoped to complete the sale.[9] Immediately after the close of the deal on August 13, the business became known as Buck.[10]
