Markets adapt to litigation faster than doctrine develops. Within months of the Serta decision, sponsors and their counsel had moved to structures that do not rely on the provision the Fifth Circuit construed. This chapter covers what replaced it.
Away from open market purchases
The immediate consequence of Serta was that transaction designers stopped relying on open market purchase provisions. If the exception means the secondary market, then a negotiated exchange with a subset of lenders does not qualify, and the pro rata sharing requirement bites.
The replacement structures achieve similar economics through different contractual routes — typically by structuring the transaction as an exchange combined with a maturity extension, so that the value transfer is embedded in terms the majority can amend rather than in a purchase that must fit an exception. The market label is extend-and-exchange, and its use in Oregon Tool's $1.1bn transaction is the most closely studied example.
The double-dip
A double-dip gives a new-money lender two independent claims against the same credit group. The typical construction: the lender lends to a subsidiary, taking a direct claim against it; that subsidiary on-lends the proceeds to the parent under an intercompany note; and the lender takes security over that intercompany note. In a restructuring the lender asserts its direct claim and the intercompany claim, participating twice in the same recovery pool.
Two features explain its popularity. It improves the new lender's expected recovery substantially without directly subordinating anyone — existing lenders keep their liens and their priority — which makes it much harder to challenge as a breach. And it can frequently be executed using ordinary intercompany lending capacity that no agreement was drafted to police. Triple-dips extend the same logic with a third claim, and the Spirit Airlines structure is the reference example.
Pari-plus and other variants
The structural inventory keeps expanding. Pari-plus transactions create a claim ranking alongside existing debt but with additional collateral or guarantee support that makes it economically senior — Trinseo is the studied case. Non-pro-rata exchanges continue in forms that avoid the specific provisions litigated. Cross-border structures relocate obligations into jurisdictions with more accommodating restructuring regimes, as in the 'international two-step' Fossil executed via the UK.
The pattern is consistent: each new structure exploits capacity that existing documents did not anticipate, is litigated or settled, and prompts drafting responses that in turn create the conditions for the next innovation.
Cooperation agreements
The lenders' response has been contractual and collective. A cooperation agreement — a co-op — binds a group of lenders not to participate in any non-pro-rata transaction unless the whole group participates, and to act together in any negotiation. If a co-op captures more than one-third of a tranche, it holds a blocking position and no majority amendment can pass without it.
Co-ops have become standard in stressed credits, frequently formed before any transaction is proposed. They represent the market solving privately what the documents could not: the coordination failure that made these transactions possible. Their limits are real — they require lenders to forgo an individually attractive opportunity, and they have themselves generated litigation — but they have measurably changed the balance of leverage in stressed situations.
