Residential Capital LLC, the bankrupt mortgage lending unit of Ally Financial Inc, has asked a court for more time to file its bankruptcy plan as any plan proposed by it will be based on the outcome of the examiner's investigation, Reuters reported on Friday. The bankruptcy court in June had appointed an independent examiner after Warren Buffett's Berkshire Hathaway Inc , a ResCap creditor, sought an examiner to review what it called "potentially improper" pre-bankruptcy transactions between ResCap and Ally. In its motion filed on Thursday, ResCap sought to extend the time to file a chapter 11 plan by nine months. Currently, the period expires on Sept. 11.
