Certain Underwriters at Lloyd's v. Abbott Laboratories, 16 N.E.3d 747

Lloyd’s underwriters issued three-layer product recall policies to Abbott for April 2000–April 2003; Knoll acquisition exceeded 5% of Abbott’s revenue, triggering a need for new premium and notifications.
Abbott disclosed the Knoll acquisition; certain endorsements required signed applications, market support, and timely payment of additional premium by July 1, 2001; initial unsigned applications and article disclosures preceded full agreement.
June 1, 2001 Wall Street Journal article about Synthroid regulatory status prompted underwriters to add subjectivities; Abbott issued a press release and communicated to brokers about pursuing NDA in parallel.
Premium for Knoll was eventually paid July 2001; some underwriters accepted with reservations, others revised terms; tolling agreement later entered October 2001 to preserve rights on Synthroid-related claims.
March 2002 Italian Sibutramine suspension triggered a Meridia-related claim; litigations framed as rescission vs coverage; court bifurcated liability (rescission) and damages phases.
Trial court: rejected rescission and found coverage ratified; damages awarded Abbott $84.5 million (policy limits) plus costs; denied prejudgment interest; awarded postjudgment interest.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Rescission based on fraud in the application	Underwriters prove misrepresentation; false knowledge/intent voids policy per 154.	Abbott lacked intent to deceive; disclosures timely; knowledge-belief standard applies and not material.	Not against weight of evidence; no misrepresentation with intent to deceive; rescission rejected.
Waiver/ratification of coverage by underwriters	Underwriters timely raised concerns; renewal of Knoll due diligence required; tolling shows non-waiver.	Acceptance of premium and continued coverage after learning facts constitutes waiver/ratification.	Underwriters ratified coverage by accepting premium; waiver supported by conduct.
Production of privileged documents for cross-examination	Privileged materials could aid impeachment and discovery.	No prejudice; documents not essential; no abuse of discretion.	denial not erroneous; any error non-prejudicial.
Postjudgment vs prejudgment interest	Damages liquid or easily calculable; prejudgment interest appropriate once final award determined.	Damage amount not liquid; award requires calculation; prejudgment interest inappropriate.	No abuse; postjudgment interest affirmed; prejudgment interest denied.
