About Mercer LLC


Mercer believes in building brighter futures by redefining the world of work, reshaping retirement and investment outcomes, and unlocking real health and well-being. Mercer’s more than 25,000 employees are based in 44 countries, and the firm operates in over 130 countries. Mercer is a business of Marsh & McLennan (NYSE: MMC), the world’s leading professional services firm in the areas of risk, strategy and people, with 76,000 colleagues and annual revenue of $17 billion. 

Different names, same business

Mercer has been in the business of making a difference in people’s lives for more than 75 years. William M. Mercer, Ltd. began in Canada and grew to become a premier provider of actuarial and benefits consulting services. After the firm was acquired by Marsh & McLennan Companies and merged with its 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 global leader in the health and benefits marketplace, 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 derive greater value from their benefits and achieve better health outcomes. Mercer’s experienced local teams, enhanced by the intellectual capital and thought leadership of our national firm, enable us to deliver advice and solutions across health, pharmacy, compliance, technology and benefits administration. Whether for a small business, domestic employer or large multinational firm, Mercer delivers health and benefits solutions that meet each employer’s unique needs. Outside the US, Mercer’s Health business goes to market with its Marsh & McLennan sister business Marsh, as “Mercer Marsh Benefits.”


Mercer is the world's largest institutional investment advisor with more than $15 trillion in assets under advisement and $321 billion in assets under 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:

  1. Defined Contribution (DC) - DC plans are now the primary source of retirement income for many individuals. Mercer's consultants work with clients to design, plan, and manage customized DC plans that can help improve retirement outcomes for employees while meeting workforce management needs. They also advise sponsors on investments, governance, and management of fiduciary risk through the firm's DC OCIO offerings.
  2. Defined Benefit (DB) - Mercer’s interdisciplinary team of specialists provide clients with holistic advice and an integrated approach to managing pension cost, size, and risk. The firm's innovative strategies can help DB plans deliver optimal outcomes to meet clients’ objectives, bringing together actuarial, administration, and investment services for a seamless experience.  A range of advisory and delegated services are available.
  3. Not-for-Profit - As a trusted advisor and recognized industry leader, Pavilion, a Mercer Practice, advises endowments, foundations, healthcare organizations and faith-based institutions on essential investment strategy decisions appropriate to their missions and spending requirements. Pavilion offers a full suite of services especially tailored for not-for-profit organizations.
  4. Financial Intermediaries - Mercer offers extensive capabilities to help financial intermediaries overcome today’s market challenges by improving governance, reducing costs, and enhancing their clients’ return potential.
