The Investment Board is an 11-member public body of dedicated professionals who serve as the trustees of the System and make decisions for the exclusive benefit of IPERS members. 

The Board holds quarterly public meetings to review actuarial findings and investment performance, and to adopt actuarial assumptions and investment policies.

Asset allocation is a process of investing across many different asset classes with the purpose of diffusing the overall volatility of IPERS' investment returns. 

The Investment Board establishes a policy benchmark that is a strategic set of target allocations for each asset class. IPERS’ investment staff strives to meet or beat the return on the policy benchmark by conserving investment management costs and prudently deploying investment risk across asset classes and strategies.
