Aon Timeline


PPA reformed pension laws and added greater accountability, while UPMIFA provided guidance for spending and investment decisions made by endowments and other non-profits. Following the global financial crisis, Aon responded to demand for aligned risk management and investment advice by merging with Hewitt Associates, which acquired EnnisKnupp prior to the merger.

Aon Hewitt became a global brand, offering innovative advisory and outsourced investment services, pension risk management, and human capital solutions. Aon divested of its employee benefits outsourcing business to invest in the alternative investment industry. Townsend Group delivers global, customized real asset investment strategies for institutional investors seeking greater portfolio diversification. In March 2020, Aon Hewitt became Aon Investments USA Inc.**

* Aon’s Operational Risk Solutions and Analytics Group is an independent entity from Aon Investments USA Inc. Investment advice is provided by Aon Investments USA Inc.

** Diversification does not ensure a profit nor does it protect against loss of principal. Diversification among investment options and asset classes may help to reduce overall volatility.
