Number of Occurrences: Insurance Coverage and Continuing-Exposure Claims, Impact of Discovery v. NFL

Key Factors That Determine an "Occurrence," Policyholder and Insurer Perspectives, Recent Case Law Developments

About the Course

Introduction

This CLE course will provide insurance counsel with updated guidance on the issue of occurrences in the context of liability claims involving continuing exposure. The panel will discuss the factors used to determine an occurrence, analyze changes in policyholder and insurer motives and strategies for resolving disputes, consider the impact of insurer vs. insurer disputes, and evaluate significant case law developments that may alter traditional assumptions on these issues.

Description

Determining the number of occurrences is often the central issue in coverage disputes involving continuing exposure or long-tail injuries and likely determines the amount of coverage available for the policyholder. Insurers and policyholders have a litany of motives and strategies when arguing in favor of or against single or multiple occurrences, and these change depending on the preferred outcome in a given case. Insurers in particular are careful about how a preferred position in one case may affect the outcome in others.

Determining the number of occurrences has only become more complex and confusing with the explosion of mass torts. Disputes about the number of occurrences increasingly involve multiple and excess carriers in the policyholder's insurance program. Expected insurer or policyholder positions can be reversed in what may appear to be similar fact patterns and produce entirely different results, such as Discovery Property & Casualty Co. v. National Football League, ___ N.Y.S.3d ___ (1st Dep't Oct. 1, 2026), and Church of Jesus Christ of Latter-Day Saints v. National Union Fire Ins. Co. of Pittsburg, Case No. 25-4049, ___ F.4th ___ (10th Cir. July 28, 2026).

Listen as our esteemed panel of insurance practitioners analyzes the key factors that determine an "occurrence" in liability policies, reviews policyholder and insurer arguments, and discusses the most recent case law developments that may change the way practitioners approach this issue.
