NEW YORK (AP) — An appeal for bankruptcy protection filing of the operator of Saks Fifth Avenue, Bergdorf Goodman and Neiman Marcus has left the luxury department stores' suppliers with unpaid bills and caused a rift with Amazon, one of Saks Global's minority investors. Saks Global said last week it had secured roughly $1.75 billion to help finance the company toward hoped-for profitability. The company said it would honor all customer loyalty programs, compensate vendors and pay employees while seeking approval for its plan to pay off outstanding liabilities, which range from $1 billion to $10 billion, according to court documents.
