More than two thirds of revenue at Arthur J. Gallagher comes
from insurance brokerage. Gallagher advises corporate and
institutional clients on managing risk and recommends insurance
products from third-party providers. Through its risk-management
business, Gallagher processes claims for its clients and provides
related services. Gallagher has had a financial services arm that
developed investments in tax-advantaged ventures, but it is winding
down some of those activities.
