Employees Retirement System of Rhode Island, Providence, will boost its allocation to non-U.S. equities by 5% of total assets. The increase will be funded from its U.S. bonds allocation. A spokeswoman for Treasurer Paul J. Tavares said the $6.6 billion funds overall equity allocation will total 72.5% and the U.S. bond allocation will decrease to 27.5%, following an asset allocation study done by Wilshire Associates. Wilshire is expected to make recommendations this month at the trustees meeting on implementation of the new asset mix. It is not yet known whether manager changes will be made, the spokeswoman said.
