Exide Technologies (Exide) filed chapter 11 on June 10, 2013. Exide's plan of reorganization (the Plan) was confirmed on March 27, 2015, and became effective on April 30, 2015. The Plan provided for the debtor to continue to pay fees pursuant to 28 U.S.C. §1930 until the case closed. On October 26, 2017, Congress amended 28 U.S.C. §1930(a)(6)(B) (2017 Amendment) to read:

The chapter 11 Debtor-utility’s propose restructuring plan filed on September 9, 2019 listed unsecured funded debt claims and general unsecured claims as unimpaired, providing that these were allowed, unimpaired claims that would be paid in full, in cash, including post-petition interest at the federal judgment rate provided in 28 U.S.C. § 1961(a), the federal judgment rate from the petition date to the effective date of the plan, which as of the filing of the petition was at 2.59%.

Factual Background
The debtor plaintiffs were Texas limited partnerships doing business in Oklahoma. Alta Mesa contracted with its defendant affiliate, Kingfisher Midstream, LLC (“Kingfisher”), to transport Alta Mesa’s oil and gas over gathering systems to be constructed by Kingfisher. Pursuant to gathering agreements governed by Oklahoma law, Kingfisher built a gas gathering system linking Alta Mesa’s wells to central collection points. In exchange, Alta Mesa promised to deliver substantially all of its hydrocarbons to Kingfisher for fixed gathering fees. Because the fixed fees proved to be expensive, Alta Mesa filed an adversary proceeding seeking, among other things, a declaratory judgment that the gathering agreements were not real property covenants, but instead executory contracts subject to rejection under § 365 of the Bankruptcy Code.
