There’s more to Mercer than the name of this category indicates. How many readers know, for example, that the consultancy offers M&A advice and due diligence? Still, human capital advisory services are Mercer’s bread and butter, whether it’s designing or administering employee benefit, compensation, health, and pension plans, or advising on talent-management strategy. Mercer’s private health exchange, Mercer Marketplace, offers the largest range of benefits products and carrier options available on any such health exchange, according to the firm.
