Serta Simmons is the complete arc of modern creditor conflict: an out-of-court liability management transaction, litigation over whether the documents permitted it, a bankruptcy that confirmed a plan protecting the participants, an appellate reversal, and a damages finding on remand. No other case lets you follow a single transaction through every one of those stages.
The transaction
In 2020 Serta faced a maturity it could not comfortably refinance. It negotiated with lenders holding a majority of its first lien term loan: those lenders would provide new money and, through an amendment passed by majority vote, the company would issue new debt secured by a priming lien. The participating lenders exchanged their existing holdings into the new senior tranche at a discount to par. Non-participating lenders kept the instrument they held, now subordinated.
The company relied on an open market purchase exception to the credit agreement's pro rata sharing requirement — a provision permitting the borrower to buy back its own debt without treating all lenders equally. Whether the transaction fit that exception is the entire case.
Litigation and confirmation
Excluded lenders sued. The bankruptcy court granted partial summary judgment for Serta, holding the 2016 credit agreement gave the company considerable flexibility and that the open market purchase provision did not require the exchange to be offered equally to all similarly situated lenders. The Fifth Circuit permitted a direct appeal.
While that appeal was pending, the bankruptcy court confirmed a plan of reorganisation over the excluded lenders' objection. The plan included an indemnity protecting the participating lenders in connection with the uptier — which meant that even if the excluded lenders eventually won, the estate would absorb the cost. That indemnity became its own issue on appeal.
The reversal
On 31 December 2024 the Fifth Circuit reversed. An open market purchase, it held, means a purchase occurring on the secondary market for syndicated loans — the designated market for that product. Competition alone is not enough; all possible buyers must have the opportunity to interact with sellers, not a preselected few. The 2020 exchange did not occur on that market, so the exception did not apply and the transaction breached the agreement.
The court also rejected equitable mootness as a bar to reviewing the confirmation order, excised the plan indemnity, and remanded the excluded lenders' counterclaims. The participating lenders sought reconsideration or certification to the New York Court of Appeals; the Fifth Circuit denied it. On remand, the Houston bankruptcy court held the participating lenders liable for approximately $400 million.
The same day as the reversal, the New York Appellate Division upheld a structurally similar uptier in Mitel on different contract language. Chapter 19 works through why.
The numbers
The 2016 credit agreement was a $2.4bn package: $1.95bn of first lien term loans and $450mm of second lien. In June 2020 the participating lenders provided $200mm of new money as first-out superpriority debt, and exchanged approximately $1.2bn of existing first and second lien loans for roughly $875mm of second-out superpriority debt.
That exchange is the whole transaction in one ratio: $875mm received for $1.2bn surrendered is about 73 cents on the dollar. The participating lenders accepted a 27% principal haircut to move ahead of everyone else. Within it, the first lien leg was struck at a different rate — participating lenders converted more than $990mm of first lien loans into about $734mm of new second-out debt, roughly 74 cents, implying the second lien leg cleared nearer 67. Those ratios are the participants’ view of what their old paper was worth. Nobody accepts a 27% haircut on a claim they expect to recover at par.
The excluded lenders — among them LCM funds holding about $7.4mm of first lien — kept their full claim and found themselves subordinated to over $1bn of new superpriority debt. Under the confirmed plan, nearly all of the reorganised equity went to holders of the exchange debt, the $200mm first-out was paid in full through a refinancing, and claims remaining under the 2016 agreements received essentially nothing.
On 7 July 2026, Judge Christopher Lopez of the Southern District of Texas held that the participants had breached the pro rata sharing provision by taking new first-lien second-out debt without sharing ratably, and awarded the excluded lenders approximately $400mm. The two provisions that decided it are worth memorising: §2.18(c), the pro rata sharing obligation, and §9.05(g), the open market purchase exception the parties relied on to avoid it.
Run these figures in the uptier exchange solver, which is preloaded with them, and then in the waterfall solver using the post-uptier preset to see the recovery gap at different enterprise values.
The documents to pull
This case is unusual in that the most valuable documents are not on the docket. Pull the 2016 credit agreement from EDGAR and read the pro rata sharing provision and the sacred rights, then do the same for Mitel's agreement. That comparison is the single highest-value hour available in this field.
Then read the Fifth Circuit opinion itself via CourtListener rather than a summary, the bankruptcy court's original summary judgment ruling, the confirmation order with its indemnity provision, and the remand decision. Supplement with three law firm alerts — Jones Day, Akin, and Cleary all published good ones — and note where they disagree.
The exercise: draft the language you would have insisted on as a lender in 2016 to prevent this, then stress-test it against the Mitel facts and against a dropdown. You will find that closing one path opens another, which is the actual lesson of Part IV.
