The Wisconsin Retirement System (WRS) Trust Funds are invested by the State of Wisconsin Investment Board.
The effect of investment returns on the benefits of WRS members is based on the rate of return as of December 31. (See Annual Returns, Rates and Adjustments.)
Once performance numbers are final, SWIB reports calendar year-to-date returns. Reporting usually takes about four weeks because privately traded investments, such as business loans, real estate and private equity, are not available until four weeks after the close of the month.
