YANKTON, S.D.(WNAX)- The South Dakota Retirement System is attempting to balance positive investment returns, staying fully funded and stable benefits to those depending on payments.

Senior Actuary Doug Fiddler told the Retirement Board this week says hitting that balance is becoming more difficult.

Fiddler says the cost of living adjustment this year will be down from last year’s three percent.

Fiddler says projected investment returns don’t promise much of an increase for next year.

The official cost of living adjustment for next year will be set by the board later this year.
