At the same time, the new laws established a high standard of fiduciary responsibility, namely adopting the prudent expert rule. Those changes permitted the investment program to modernize, resulting in investment income and gains of more than $13.6 billion over the past twenty-five years. This growth in assets has been achieved during a time when the fund has earned 10.0 percent per year. During this same period, funding by the State of Illinois fell far short of both the actuarial and statutory requirements, missing an opportunity for SURS to significantly reduce, if not eliminate, its unfunded liability. As of December 31, 2008, SURS uses 40+ direct investment managers, of which 20+ are minority-owned or female-owned. SURS also has 17+ indirect investment managers, all of which are minority-owned or female-owned. Minority-owned and female-owned investment managers invest over 10% of the System's total assets. More than 25% of the SURS portfolio is indexed or passively managed.
