Different names, same business

From the beginning, Mercer has been in the business of putting people's futures first. In 1945, William M. Mercer, Ltd began in Canada and grew to become a premier provider of actuarial and benefits consulting services. Acquired by Marsh & McLennan Companies in 1959 and merged with their own employee benefits department, the firm expanded through growth and acquisition to become a global leader in health, wealth and career.

Breaking down the business

Mercer organizes its business around three key areas: Health, Wealth and Career, each with distinct areas of practice.


Mercer is a leader in the health and benefits marketplace globally, and is the largest health benefits broker in the United States. The firm delivers trusted advisory services, brokerage and innovative solutions that help employers and their employees improve the quality, cost and experience of healthcare. Whether a small business, a domestic employer, or a large multinational firm, Mercer can deliver custom health and benefits solutions that meet unique client needs. Mercer provides access to local market thought leaders as well as national and international resources that advise on regulatory compliance and innovative strategies across health benefits, pharmacy, network providers and population health. Outside of the US, Mercer’s Health business goes to market with its Marsh & McLennan Companies sister company, Marsh, as “Mercer Marsh Benefits”.


 Mercer is the world's largest institutional investment advisor with more than $12 trillion in assets under advisement and $282 billion in assets under delegated management. The firm is also a global leader in the provision of actuarial and related services. Its Wealth business provides services to clients in four broad areas:

Defined Benefit (DB) - Mercer’s consultants provide clients with a holistic view of assets and liabilities within their pension plans.  The firm's innovative strategies help clients take advantage of market opportunities and execute both asset and liability transactions efficiently.

Clients also often come to Mercer for its change capabilities in support of organizational changes and technology implementations - areas which all practices touch on.

The company's extended offerings include a dedicated M&A business, which is part of its Multinational Client Group.

Multinational Client Group (includes M&A Consulting and International Consulting)

Defined Benefit Plan Sponsors Reassessing Long-term Goals due to Volatile Markets and Uncertain Costs

With the benefit of a decade of generally positive market performance, a growing number of plan sponsors report improvements in their funded status, making it more economically feasible for many defined benefit (DB) plans to actively de-risk and rethink their investment governance approaches.

The Sequel models three climate change scenarios, a 2°C, 3°C and 4°C average warming increase on preindustrial levels, over three timeframes – 2030, 2050 and 2100. The longer timeframe (Mercer’s 2015 report was modeled to 2050) provides greater visibility into the expected impacts of natural catastrophes and resource availability for each temperature increase.

With more business disruption expected, making organizations “future-fit” is top of mind, new study finds

Mercer’s 2019 Global Talent Trends study identifies four top trends shaping the future of work. Nearly two-thirds (65%) of executives in the United States predict significant disruption in the next three years, compared to 35% in 2018. As executives focus on making their organizations “future-fit”, significant human capital risks – including the ability to close the skills gap and overcome employee change fatigue – can impede transformation progress. Addressing these concerns is paramount, given that only 37% of executives rate their company’s ability to mitigate human capital risks as very effective.
