How a Single Catastrophe Can Change the Way We Manage RiskU.S. Property Practice Leader at Marsh National Property Claims Practice Leader at Marsh

After Hurricane Katrina, which killed more that 1,800 people and incurred more than $41 billion in insured losses, risk professionals, residents, and government officials looked at what worked and what did not in mitigating the damage from the storm. It is the type of dialogue that plays out after most major disasters, any one of which has the potential to change approaches to risk management and offer lessons in risk transfer.
From a financial perspective, some of the most significant changes following this type of disaster have to do with the impact on insurance and risk transfer.
After Katrina, experts developed a greater sophistication in the financial modeling of insured risks, and credit rating agencies began looking at how insurers and reinsurers used modeling in their capital management strategies. Companies after Katrina that failed to demonstrate strong capital management for catastrophe risks faced downgrades of their credit and financial strength ratings. The rating agencies’ emphasis on capital management also sharpened insurers’ focus on accurate risk modeling.
Katrina also opened the door to non-traditional forms of capital, including:
- Sidecars: Special-purpose vehicles that provide fully collateralized reinsurance enable investors to commit capital to specific sets of risks for shorter durations with a predefined exit plan. Following Katrina, many insurers and reinsurers set up sidecars to provide additional sources of underwriting capacity. These have since attracted billions of dollars in capital.
- Insurance-linked securities: These vehicles include catastrophe bonds, which were seldom used before Katrina but are now widely issued.
Insurance Lessons Prove Every Word Counts
Every disaster provides this simple lesson: Insurance policy wording matters. Katrina, Superstorm Sandy in 2012 and other disasters have brought a focus on the definitions of particular perils, such as “named windstorm,” “flood,” and “windstorm.” Millions of dollars can be at stake, and disputes often take years to sort out in court.
A series of devastating earthquakes that struck between February 2010 and March 2011 — notably in Chile, New Zealand and Japan — provided a number of lessons related to insurance recovery and claims:
- It is essential to declare values accurately to insurers. Underinsurance was highlighted in these events, which can result in significant differences in recoveries post-loss.
- Contingent business interruption coverage is necessary because catastrophes can have consequences outside the territory of the loss and for customers and suppliers not directly involved in the event.
- It is important to understand how policies apply deductibles and sub-limits. Policyholders should recognize differences in how their policies define deductibles and the circumstances under which coverage is sub-limited.
Every disaster provides this simple lesson: Insurance policy wording matters.
One way to work through potential policy issues is to perform a drill, much the same way a building has occasional fire drills. And yet, in the past two years, fewer than 25 percent of companies have tested how their property policies would respond to a major loss, according to a recent Marsh Risk Consulting survey.
Organizations Must Improve Business Continuity Planning
In 2011, two separate events demonstrated the way natural disasters can ripple through supply chains. Floods that hit Thailand that year highlighted the ramifications of a single event. The flooding was the worst the country had seen in more than 50 years, a period during which the country had grown into a key link in the global supply chain. The other event was the devastating earthquake, tsunami and nuclear emergency in the Tohoku area of Japan.
One of the key failures following both these events was that some organizations’ continuity plans were incomplete, inadequate or not aligned with the needs of a global organization. As an example, consider the business continuity plan of one Japanese manufacturer. The tsunami displaced or destroyed molds needed for the creation of some critical components, and the company found after the tsunami that the contractors familiar with the casts to recreate the molds were missing or dead. The continuity plan did not address the loss of these critical resources, nor did it address further complications caused by rolling power outages and nuclear contamination.
A key lesson, then, is that a plan on shelf is not enough. Optimizing resiliency and efficiency requires discipline, analytics, decision modeling and the involvement of a broad cross-section of business, technology and operation leaders.
How Data and Analytics Can Help
Hurricane Katrina brought about a major change in thinking about catastrophe (CAT) modeling, used to develop estimations of financial losses. Today, virtually every risk with catastrophe exposure is run through one or more models. Hurricane Katrina led to a sharp rise in the focus on data quality: initial loss estimates from Katrina missed the mark by a long shot in part because the data loaded into the models was inadequate, incomplete, inaccurate or miscoded. CAT models at the time overestimated the impact of pure wind damage and underestimated the damage from flooding and storm surge, meaning initial damage estimates identified only about one-fourth of the damage.
Today, insurers bring multiple perspectives to a particular loss potential, and insured persons provide more detailed information about their properties. Unique construction characteristics — for example, flood defense systems and first-floor building elevations — are now more accurately depicted.
Hurricane Ike, which struck in 2008, was unusual in that hurricane-force winds persisted inland far longer than was then considered possible for a tropical cyclone and caused more $13 billion in insured losses stretching far north. Hurricane Ike demonstrated that windstorms can have a wide impact inland and that preparedness should not be limited to coastal locations. In 2012, from a modeling perspective, insurers were better prepared for losses from Superstorm Sandy because they had stress-tested their underwriting portfolios.
Crisis and Societal Risk Management Remain a Top Priority
Hurricane Katrina highlighted the need for public and private sector entities to develop plans before an event. There were many changes in both government and private industry planning for disasters following Katrina. For example, the U.S. National Response Framework, which defines the role of all federal agencies, was updated in 2006 based on the collective experiences in responding to hurricanes Katrina, Wilma and Rita the previous year. The primary improvements were focused on communication and coordination among government agencies.
In addition, most businesses had developed risk-specific plans before Katrina —for hurricane, flooding and loss of power. Yet most had not cross-walked those plans to see how they would affect a coordinated response. Now the emphasis is on ensuring there is a broad response structure in place.
The ever-increasing number of people at risk from natural disasters is critical for governments and international organizations. They, too, look to learn after disaster strikes. The International Council for Science has cited numerous examples of successful implementation of lessons learned following major catastrophes, including:
- In India, a combination of radars and improved means of communication was deployed following a 1977 super cyclone that killed more than 20,000 people.
- Following the 1995 Kobe earthquake, Japan put in place an earthquake early warning system, which is credited with saving lives during the 2011 Tohoku earthquake.
- Following the 2004 Indian Ocean tsunami, India established a tsunami warning center.
Meanwhile, the World Economic Forum has laid out a Vision for Managing Natural Disaster Risk that focuses on:
- Raising awareness.
- Enhancing resiliency.
- Encouraging preparedness.
Those are, of course, some of the key issues at the level of the individual organization and critical lessons to be applied in readiness for the next disaster.
