 In 2008, Harvard Business School published a case documenting how the acquisitions were restructured and rebranded to create a preeminent firm based on specialization and industry expertise.Although the oldest organization now incorporated into the company can be traced back to 1969, the modern firm was created in 2003 through a merger of Oliver, Wyman & Company with Mercer's financial services strategy & risk units.The acquisition came towards the end of a wave of purchases by Mercer in the United States, including consultancies Temple, Barker & Sloane bought in 1987, Strategic Planning Associates in 1989, and David Nadler's Delta Consulting Group which became "Mercer Delta" in 2000.
