SEC Charges Chicago-based Aon Investments and Former Partner with Misleading Pennsylvania Public Employees’ Pension Fund

The Securities and Exchange Commission today announced settled charges against Aon Investments USA Inc., a Chicago-based registered investment adviser, and the firm’s former partner, Claire P. Shaughnessy, for misleading their client, the Pennsylvania Public School Employees’ Retirement System (PSERS), about the reason for a discrepancy between two different calculations by Aon of PSERS’s investment returns for the same period. The SEC’s orders find that Aon was responsible for calculating PSERS’s investment returns for “risk share,” a provision under Pennsylvania law that requires public school employees to contribute more to their pensions if the retirement fund does not meet certain investment return rates.
