The Illinois Teachers' Retirement System says it expects a lower return on its pension investments in the next year. That means the state will have to cover more of the cost of teacher pensions.
TRS says it's still a good assumed rate of investment return at 7.5 percent. That falls in line with similar pension systems nationwide. But it's not as profitable as 8-percent, which TRS had been using for the previous few years.
Dave Urbanek is with TRS. He says the unpredictable nature of the international economy spurred the decision to lower the rate.
