In re Polyurethane Foam Antitrust Litigation, 152 F. Supp. 3d 968

Background

Multiple civil class actions by direct purchasers followed international and U.S. raids and an inadvertent public filing revealing a DOJ affidavit alleging price-fixing among major flexible polyurethane foam producers; cases consolidated for pretrial proceedings.
Extensive discovery, depositions, and partial settlements occurred; one defendant (Woodbridge Fabricating) pled guilty to a limited Sherman Act price-fixing offense; several Canadian firms admitted coordinated conduct in Canada.
Plaintiffs (Direct Purchasers) allege a single, horizontal conspiracy to coordinate percentage and timing of price increase announcements (PIAs) for slabstock and underlay foam, using PIAs to establish a common baseline for customer negotiations.
Plaintiffs rely on: numerous competitor communications (emails, faxes, call logs), exchanges through scrap brokers, Cooperating Defendants’ admissions about industry coordination, evidence that senior employees with pricing authority exchanged draft and published PIAs, and expert econometric models of classwide impact.
Defendants moved for summary judgment arguing: no direct evidence of an overarching agreement; observed parallelism reflects lawful oligopolistic interdependence; PIAs often did not change transaction prices; many contacts were innocuous or related to supplier/customer relationships; and plaintiffs’ expert impact model is unreliable for parts of the class.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Existence of a horizontal price‑fixing conspiracy	Communications among senior employees, exchanged draft/published PIAs, admissions by cooperating firms, Woodbridge plea create inference of agreement	Evidence is circumstantial, often innocuous, reflects lawful oligopoly behavior or supplier/customer interactions; no explicit global agreement	Denied summary judgment — jury question exists whether circumstantial evidence and admissions permit inference of conspiracy
Direct v. circumstantial evidence standard	Some documents and admissions are direct; many communications are powerful circumstantial proof plus factors	No document is explicit enough to be "direct evidence" that requires no inference	Court finds no direct evidence as to moving defendants; analysis proceeds under circumstantial (plus‑factor) framework
Impact / classwide damages (expert testimony)	Leitzinger’s econometric model shows classwide overcharges and can support inferences for missing or nonestimable subsets	Model fails for some MBIDs; predicts implausible but‑for prices for some periods; omits certain transactional data (e.g., automotive slabstock, Woodbridge)	Expert admissible for trial; models create triable issues, but summary judgment granted for purchases tied to 2,266 negative impact coefficients
Statute of limitations / fraudulent concealment tolling	PIAs provided pretextual reasons and methods (private emails, use of brokers, redacted faxes) that affirmatively concealed the conspiracy; plaintiffs exercised reasonable diligence	Plaintiffs had suspicion from similar PIAs and thus should have inquired; no active concealment as a matter of law	Denied summary judgment — factual disputes on active concealment and due diligence make tolling a jury question
