Except in small business cases and cases proceeding under subchapter V of chapter 11 of the Bankruptcy Code, prior to the first date set for hearing on a disclosure statement, a chapter 11 plan proponent shall apply for an order fixing a deadline by which proofs of claim or interest must be filed. The plan proponent in a small business case shall apply for said order no later than the date the first plan is filed. The court will fix the deadline without an application in cases proceeding under subchapter V of chapter 11 of the Bankruptcy Code. Upon entry of an order fixing the deadline, the plan proponent shall transmit to each creditor and equity security holder a copy of the order or notice containing such deadline. Unless otherwise ordered, notice of the deadline shall be a separate document.
