Ibex, an American producer of woollen outdoor apparel, is planning to shut down, according to SNews. It has already laid off more than half of its 40 employees. Its assets have been taken over to place them in liquidation. After its takeover in 2010 by a private equity firm, North Castle Partners, Ibex opened single-brand stores in Boston, Seattle and Denver, while working more closely with key accounts, but the strategy didn't work.
