ISBI invests for the long-term value of its beneficiaries, seeking to meet long-term return objectives while maintaining prudent risk exposure, controlling fees and expenses, and complying with the governing provisions of the Illinois Pension Code and other applicable laws and regulations.

Asset Allocation

ISBI recognizes that the fund’s diversification across asset classes is the primary determinant of meeting risk-adjusted return objectives over time. Therefore, ISBI sets target allocations for various asset classes and the portfolio is periodically rebalanced to meet those targets.
