West Virginia Investment Management Board, Charleston, hired Barclays Global Investors as its first mortgage index fund manager and Hoisington Investment Management as an additional domestic fixed-income manager with an interest-anticipation mandate, said Craig Slaughter, executive director of the $5 billion fund. Barclays will run $900 million and Hoisington will run $200 million, he said. Funding will come from reducing a $2 billion domestic fixed-income portfolio managed by Western Asset Management. Performance was not an issue, he added. Summit Strategies Group assisted.
