Windstream had recently requested the maximum, legally allowable extension to August 25 (filing date) and October 26 (solicitation date). The original exclusivity deadline was this week.
For obvious reasons, the creditors balked, so Windstream modified its request to:
New Filing Exclusivity date request: through May 31, 2020
This is the period when Windstream management, as "debtor-in-possession" (DiP), has the exclusive right to file a plan of reorganization. Unless Windstream somehow loses DiP status (unlikely), no other entities (creditors, hostile acquirers, etc) are permitted to submit competing plans
New Soliciting Exclusivity Period request: through July 31, 2020
After the exclusivity date, Windstream then has the exclusive right to solicit support for its plan among various stakeholders (i.e., the different creditor groups).
