Washington State Investment Board, Olympia, may put up for bid $18 billion in indexed equity assets, now managed by Barclays Global Investors, as part of a normal review, said Gary Bruebaker, chief investment officer for the $53 billion system. That total includes $16.5 billion invested in a broad-market portfolio for the defined benefit plan, plus three portfolios for the state’s defined contribution system. The board is expected to vote on the proposal Thursday. R.V. Kuhns is consultant.
