Fifth Circuit Affirms Application of Securities Exclusion [Alert]

Rafael Rivera discusses Gleason v. Markel American Insurance Company and the importance of the wording of securities exclusions in D&O policies.


Professional liability is one of the most fluid segments of the insurance industry because the potential exposures and insurance products change constantly in response to market conditions. Cozen O’Connor’s team of recognized professional liability coverage attorneys practice on the cutting edge of this dynamic and high-stakes field.

Our firm serves domestic and international insurers of the full range of professional specialties, from banking and investment to law and healthcare. We have experience with virtually all categories of professional liability coverage.

Our attorneys are particularly well known for their work as insurer counsel with respect to directors and officers (D&O) and errors and omissions (E&O) policies. From the insider trading scandals of the 1980s to the financial crisis of 2008, Cozen O’Connor has played a critical role in most major professional liability coverage disputes in recent memory.

The firm also includes attorneys who focus on medical, legal, accounting, architectural, and other professional coverage. These types of policies are unique because they are structured around the duties, language, and norms associated with specific industries. Through decades of careful service, our attorneys have developed deep and essential knowledge about the underlying covered professions.

Cozen O’Connor assists insurers in all aspects of policy development and claims handling, including policy design and drafting, bordereau reporting of E&O and D&O programs, coverage analyses, claims investigations, mediations, settlement negotiations, and trials. Our goal is to resolve issues quickly and amicably, but we are absolutely prepared to take large coverage cases to verdict when necessary.

The firm is also distinguished by its geographic scope. With offices in 26 cities across the United States, as well as in London, Montreal, Toronto, and Vancouver, we have the capability to respond wherever and whenever coverage issues arise. Cozen O’Connor can offer clients premier service in every jurisdiction in the country at rates that are transparent and sustainable.
