That lawsuit charges Neiman Marcus with "among other wrongdoings, the fraudulent transfer of assets totaling approximately $1 billion of value for no consideration." The allegations are related to Neiman's move this September to shift its MyTheresa e-commerce business to a corporate entity held by its private equity owners. The business is seen as one of its most valuable remaining assets. Marble Ridge also argues that Neiman Marcus won't be able to pay down its debt as it matures.
