The children's clothing chain, which was founded in 1976, started out as a music and play center and grew to a major global retailer with more than 1,000 stores, before being bought by Bain in 2010. The bankruptcy filing came with funding and creditor support to restructure the company, which involved Gymboree closing about 330 stores worldwide. During the restructuring, Bain handed control to a group of lenders including Brigade Capital Management, Oppenheimerfunds and Apollo Global Management LLC.
