GAM Holding AG will start paying back investors in its frozen bond funds, but some will get money out faster than others. The Swiss firm will initially return 74 percent to 87 percent of the assets in Luxembourg and Irish-domiciled funds that were previously run by suspended bond manager Tim Haywood. Investors in Haywood’s Cayman Islands-based hedge fund will only get about 60 percent in early September, with another 5 percent expected by the end of that month and the remainder paid out over time depending on market conditions.
