Willis Towers Watson provides insurance brokerage, risk management and human capital consulting services, helping businesses find and negotiate commercial insurance coverage while also advising on employee benefits and compensation programs. As an insurance broker, the company acts as an intermediary between businesses seeking insurance coverage and the insurance companies that underwrite policies, earning commissions and fees rather than taking on underwriting risk itself. Its human capital and benefits consulting business advises companies on retirement plans, health benefits and executive compensation, a service line that's less directly tied to insurance market cycles than its core brokerage business. Willis Towers Watson's revenue tends to be relatively resilient since businesses need ongoing insurance coverage and benefits administration regardless of economic conditions, though large corporate clients occasionally shift brokers, creating some client retention risk across the industry.
