Claims professionals and risk managers alike will readily attest to the complex, sometimes frustrating nature of business interruption (BI) claims. Pursuing, adjusting, and ultimately resolving these claims hinges on the ability to apply appropriate accounting principles and accurately interpret policy language. One resource on which insurance professionals have increasingly relied is Business Interruption: Coverage, Claims, and Recovery, which provides a roadmap for navigating BI claims from inception to settlement. In anticipation of the arrival of the second edition later this month, Claims spoke with Daniel Torpey, one of the book's authors, who shed some light on impediments to accurately calculating BI loss and resolution options.   Q. I noted this is the second edition to Business Interruption: Coverage, Claims, and Recovery. What prompted you to write another edition? What's new? A. This second edition of Business Interruption: Coverage, Claims, and Recovery contains expanded chapters, as well as new chapters to address the emerging issues. For instance, Chapter 10 discusses Federal Emergency Management Agency (FEMA) claims and the Public Assistance Act claims process, as well as the increasingly prominent and important role that FEMA plays in U.S.-based disasters and recovery. This past decade has also shown a continued increase in the globalization of today's Fortune 1000 companies, the changing workforce, and the ever-increasing need for companies to do more with less. An earthquake in Chile, a volcanic eruption in Iceland, or a civil uprising in Egypt are no longer considered non-issues for U.S. companies; they now impact their supply chains or customer bases. Those concerns, combined with an economic need to recover all losses have provided us with a wealth of material for an updated edition of the book. Even at the present moment we see that the earthquake and tsunami in Japan will impact the U.S. and worldwide markets.
