State of Wisconsin Investment Board (SWIB) announced today that Michael Williamson will retire as executive director at the end of 2017. The Board of Trustees will launch a nation-wide search for the next executive director and plans to have the position filled prior to Williamson’s retirement.

The Board of Trustees hired Williamson as executive director in June 2012. Under Williamson’s leadership, SWIB continued its tradition of being a valuable partner for the state of Wisconsin and its public employees. In the five years since Williamson joined, SWIB added over $1 billion above market returns for the funds it manages, while vastly improving the infrastructure of systems, controls and measurement used to run the organization. During Williamson’s tenure, SWIB’s above-market returns contributed significant value to the Wisconsin Retirement System (WRS) which is one of the country’s best-funded public employee retirement systems. SWIB’s investment returns generally account for over 75 percent of WRS income. Read the full release here.
