It is a warm, humid spring day in Dallas/Fort Worth when strong thunderstorms begin to develop alongside a high-altitude weather system that includes strong winds and convective energy coming from the Rocky Mountains.

By mid-afternoon, the atmosphere reaches a tipping point. A massive supercell thunderstorm along the weather front produces large, damaging hail and what is later designated as an EF5 tornado, with winds in excess of 200 mph.

The most recent tornado of this size as designated by the National Weather Service was on May 20, 2013, when an EF5 struck Moore, Okla., killing 24 people, flattening neighborhoods and schools, and injuring more than 350 people.

This Texas tornado is much, much worse.

Moving in the usual southwest to northeast direction, it creates a damage path about 1 mile wide and nearly 200 miles long, and directly strikes the Comanche Peak Nuclear Power Plant in Glen Rose, Texas, about 40 miles west of Fort Worth and 60 miles west of Dallas.

The power plant’s reactor was built to withstand winds up to 300 mph, but it can’t withstand what happens after the tornado throws around multiple gas-filled tanker trucks, which explode and kill numerous workers.

Matthew Nielsen, director of Americas product management at RMS, created the model for our Comanche Peak Nuclear Power Plant black swan scenario.

Debris fills the air as the powerful winds destroy much of the plant’s emergency equipment, making it impossible to maintain proper conditions and temperature within the reactor. The remaining power plant workers feverishly try to manually shut down the nuclear reactor before it melts down. They can’t.

When the reactor’s heat exceeds the ability of the plant’s processes to cool it down, radioactive gases begin to snake their way into the funnel stacks. The radioactive contamination is carried by the ferocious winds directly toward Dallas/Fort Worth.

Communication fails as area power lines go down, so it is difficult to warn the 7 million residents of the Metroplex, as Dallas/Fort Worth is known. Residents know the tornado has been sighted and try to prepare, but they don’t know that deadly airborne toxins are being carried toward them.

The Damage

About 10,000 homes and 700 commercial structures in the direct path of the tornado are completely destroyed and another 35,000 suffer damage, according to a model built by RMS. Roofs are ripped off apartment houses and multi-family dwellings. Vehicles are tossed around like toys, and with the storm striking at rush hour, workers on the roads are exposed to flying debris and high winds.

Even with residents sheltering in basements and safe rooms, fatalities reach into the 500-700 range — putting this event in line to be the deadliest tornado in U.S. history, after the Tri-State tornado of 1925, which killed 695 people in Missouri, Illinois and Indiana.

But it is the unseen radioactive contamination that ultimately makes the deadliest mark on the area.

Immediate fatalities from radiation poisoning number about two dozen, but as the contaminated rainfall seeps into the ground soil and water supply, the long-term health of the residents — and their descendants — is jeopardized. So, too, are the cattle and other agricultural products of Texas, which leads the nation in the number of ranches and farms it holds.

Chernobyl and Fukushima are the only events of a similar nature, even though the United States has seen its own recent near misses.

The radioactivity causes large swaths of area to be cordoned off, making it difficult to repair transmission and power lines as well as homes and businesses.

“The hard truth is that many businesses will close and many people will move from the area,” said Todd Macumber, president of international risk services, Hub International.

Chernobyl and Fukushima are the only events of a similar nature, even though the United States has seen its own recent near misses.

In 2011, a tornado knocked out power to the Browns Ferry Nuclear Power Plant near Huntsville, Ala., requiring the shut down of its three reactors. The plant fired up backup diesel generators until power was restored. The storm also disabled the plant’s sirens, which are needed to warn nearby residents in a crisis.

That same year, a tornado barely missed damaging 2.5 million pounds of radioactive waste at the Surrey Power Station in southeastern Virginia, although it touched down in the plant’s electrical switchyard and disabled power to the cooling pumps. The operators needed to activate backup diesel generators to run the two reactors until power was restored.

Twenty-eight years after the radioactive disaster at Chernobyl in 1986, some parts of the Ukraine remain a toxic wasteland. And in Japan, an initial evacuation area of about 2 miles surrounding the Fukushima Daiichi Nuclear Power Plant was soon widened to about 12.5 miles.

About 300 tons of  highly radioactive water has leaked from storage tanks at the Fukushima Daiichi Nuclear Power Station.

Now, three years after three of Fukushima’s six reactors melted down, the area is still unlivable and 40 miles away, diagnoses in children of thyroid cancer, which is caused by radiation poisoning, are skyrocketing, according to some reports.

Nearly 16,000 people died in the 2011 earthquake and tsunami that struck Japan, causing the meltdown. About 160,000 people were evacuated, 130,000 buildings were destroyed and $210 billion in damage was sustained.

The Texas scenario has a lot of variables, said Matthew Nielsen, director of Americas product management at RMS, who created the model for our Comanche Peak Nuclear Power Plant black swan scenario.

The likelihood of a tornado, with thunderstorms and hail, causing massive structural damage is about 1 in 200 years, he said. Such an event would result in at least $20 billion in insured losses and uninsured losses of about the same amount.

But a tornado following the exact path as this scenario — striking the power plant and heading into the Dallas/Fort Worth Metroplex — has a much, much smaller chance — about 1 in 10,000 years.

“Given the fact that tornadoes are very rare, it isn’t something that I think people should be screaming and running around frantically about,” Nielsen said. “But it’s certainly something that could happen.”

As for losses due to the radiation? “There’s not a lot of historical data points that we can confidently say that that portion would be x or y billion,” he said.

The Recovery

Any rebuilding will be delayed by the threat posed by radioactive contamination, which may spread over a large area via the thunderstorms and storm water runoff.

From an insurance perspective, all personal and commercial lines of insurance have a nuclear energy hazard exclusion. American Nuclear Insurers (ANI) provides third-party liability insurance for all power reactors in the United States.

“We are responsible for the insurance coverage protecting the operators from claims alleging bodily injury or property damage offsite from [radioactive] materials,” said Michael Cass, vice president and general counsel at ANI, a joint underwriting association with 20 insurance company members.

082014_02_cs_tornado_nuclear350pxNEWThe ANI was created under the Price-Anderson Act of 1957 and provides a primary policy limit of $375 million for claims due to offsite consequences from the release of radioactive materials from the 100 operating nuclear power plants in the United States. It also covers some plants that are shut down or in the process of being decommissioned, he said.

The ANI also covers costs related to emergency response and evacuation, including food, clothing and shelter, he said.

The joint underwriting association also administers an additional excess layer of about $13.2 billion, the costs of which would be borne by the power plant operators, and would be apportioned equally among them.

For any claims above $13.6 billion (which includes both the primary and excess layers), the Price-Anderson Act requires the U.S. Congress to “take steps to come up with a scheme to provide full compensation to the public and to continue claims payments,” Cass said.

“They could assess or tax the energy industry in some fashion or form. It doesn’t say that specifically, but that is what is alluded to.”

None of the insurance companies that are ANI members would be adversely affected if such a black swan event were to occur, he said.

“There would be a loss reserve recorded on their balance sheets, per participation in our pool, but we do have funds set aside for these catastrophic events where we wouldn’t be requiring any additional funds,” Cass said.

Damage to the power plant itself would be covered by Nuclear Electric Insurance Ltd., which insures electric utilities and energy companies in the United States. Current limits are $1.5 billion per site on the primary program, and up to $1.5 billion per site in its excess program.

Allan Koenig, vice president, corporate communications at Energy Future Holdings, which operates Comanche Peak, said the plant is robustly protected. It has two independent systems that can provide off-site power as well as backup diesel generators, to allow the units to be safety shut down in the event of natural catastrophes.

He also noted the plant has safety shields for fuel storage casks, a 45-inch-thick steel-reinforced concrete containment building wall, and fire protection redundancies.

As for the affected businesses and homeowners, they may be left in a swirling vortex of coverage confusion. The situation would have the flavor of what happened after Superstorm Sandy, when coverage often depended on whether damage was caused by flooding or wind surge.

The question for Texas insureds would be whether the damage was caused by the tornado or by the radioactivity.

“It’s an incredibly complex question and a complex issue that is really only solvable and resolvable if and when the incident occurs,” said John Butler, vice president of the environmental practice at Hub International.

“What it boils down to is the chicken and the egg scenario,” he said. “What came first? Either event has the ability on its own to create a total loss.”

Resilience and redundancy should be the key takeaways from this, said Peter Boynton, founding co-director of the Kostas Research Institute for Homeland Security at Northeastern University in suburban Boston.

“If we can retain a percentage of the critical function of whatever system we are talking about, the difference between 0 percent and 30 percent when the bad thing happens is huge.” — Peter Boynton, founding co-director of the Kostas Research Institute for Homeland Security, Northeastern University

Instead of viewing catastrophic events from an emergency management perspective, where the discussion revolves around what was — or was not — managed well, it’s better to look at the way design can lead to “continuity of function,” he said.

When Boynton was head of emergency management for the state of Connecticut, he managed the statewide response in 2011 to Hurricane Irene, which knocked out 70 percent of the state’s electric grid, leaving residents unable to access many gas stations, ATMs and grocery stores.

If the state had designed a “resiliency approach” prior to the event, it could have built in a pre-determined amount of redundancy into the system so that, say, an additional 20 percent or 30 percent of the grid remained viable.

“If we can retain a percentage of the critical function of whatever system we are talking about, the difference between 0 percent and 30 percent when the bad thing happens is huge,” Boynton said.

In the Texas scenario, if the crisis planning included a redundancy for warning nearby residents even when the power and communication lines failed — such as by using satellites to create a minimal level of continuity — the amount of death and destruction could have been lessened.

“Otherwise, we really are setting ourselves up for an impossible discussion,” he said. “You can’t just pick up these pieces at the moment of crisis. You have to understand how system design can play a role.”

Analyzing such a black swan scenario is a useful exercise, said Justin VanOpdorp, manager, quantitative analysis, at Lockton.

“Can this actually happen? Yes. Will it? Maybe not,” he said. “I think what it does is, it helps to think through it just to be prepared for those situations when they do arise.”

Buyers Beware: General Liability Outlook May be Shifting

Buyers should focus on building a robust GI program and risk management infrastructure to lessen the impact of emerging GI trends.
By: | July 5, 2016 • 6 min read

The soothing drumbeat of “excess capital” and “soft market” to describe the general liability (GL) market is a familiar sound for brokers and buyers. Emerging GL trends, however, suggest the calm may not last.

Increasing severity of GL claims may hit some sectors like a light rain at first, if they have not already, but they could quickly feel like a pelting thunderstorm in others. A number of factors could contribute to the potential jump in GL prices for certain industry segments or exposures, possibly creating “micro” or niche hard markets in the short-term, and maybe even turning the broader market over the longer-term.

“There are trends we’re seeing that will play out slowly. Industries that carry more general liability exposure will and have been hit first and hardest, but it won’t apply across the board initially,” said David Perez, Senior Vice President and Chief Underwriting Officer, for Liberty Mutual Insurance’s National Insurance Specialty operation. “There is ample capital in the market today, which allows a poor performing account to move its policy frequently from carrier to carrier. Poorer performing classes, however, will likely face increased pricing for GL policies and a reduction in capacity.”

The good news for buyers is that they can take action today to lessen the impact these trends and the evolving market may have on their GL programs.

David Perez on the state of the GL market.

Medical and Litigation Trends Drive Severity

One factor increasing claim severity is the rising cost of health care, driven both by greater demand and by medical inflation that is growing faster than the Consumer Price index.

The impact of rising medical costs on commercial auto is well-known. Businesses with heavy transportation exposures are finding it more difficult to obtain coverage, or are paying more for it.

That same trend will impact general liability, just on a slower and more fragmented basis.

LM_SponsoredContent“In light of these trends, brokers and buyers should seek to understand how effectively their current or potential insurers defend GL claims, particular in using evidence-based medicine to assess and value the medical portion of a claim, and how they can provide necessary care to claimants while still helping clients control their total cost of risk.”

— David Perez, Senior Vice President & Chief Underwriting Officer, National Insurance Specialty, Liberty Mutual Insurance

“It takes longer for medical inflation to register through the tort system in general liability than it does in auto liability (AL) because auto claims are generally resolved more quickly,” Perez said. “But the same factors affecting severity in AL also exist in GL and as a result, it’s foreseeable that we will not only see similar severity trends in GL, but they may in fact be worse than we’ve seen in commercial auto.”

Industries with greater exposure to severity in general liability claims should be the first wave of companies to notice the impact of medical inflation.

“Medical inflation will drive up costs across the board, but sectors like construction and product manufacturing have a higher relative exposure for personal injury lawsuits.”

The impact of medical inflation on the GL market.

Beyond medical inflation, two litigation trends are increasing GL damages. First, plaintiffs’ lawyers are seeking to migrate the use of life care plans—traditionally employed only for truly catastrophic injuries—to more routine claims.  Perez recalled one claimant with a broken thumb and torn ligaments who sought as much as $1 million in care for the injury for the rest of his life.

Second, the number of allegations of traumatic brain injuries (TBI) in GL claims is growing.  It can be difficult to predict TBI outcomes initially and poor outcomes can be expensive and long tailed.

“In light of these trends, brokers and buyers should seek to understand how effectively their current or potential insurers defend GL claims, particular in using evidence-based medicine to assess and value the medical portion of a claim, and how they can provide necessary care to claimants while still helping clients control their total cost of risk,” notes Perez.

Changing Legal Landscape

Medical inflation and litigation trends are not the only issues impacting general liability.

Unanticipated changes in court interpretations of policy language can throw unexpected pressure on GL pricing and capacity.

Courts sometimes issue rulings interpreting policy language in a manner that expands coverage well beyond the underwriter’s original intent. Such opinions may sometimes have a retroactive effect, resulting in an immediate impact on not only open, but also closed cases in some circumstances.

Shifts in the Marketplace

In addition to facing price increases, GL brokers and buyers will be challenged by slightly shrinking capacity due to consolidation and repositioning among carriers in the marketplace. “Some major carriers have scaled back their GL writing, resulting in a migration of experienced senior management. As these executives leave, they take their GL expertise and relationships with them, resulting in fewer market leaders and less innovation,” Perez said.

“Additionally, there are new carriers coming into the business that may not have the historical GL loss data to proactively identify trends or the financial strength and experience to effectively service their GL customers and brokers. Both trends make it important for brokers and buyers to work with an insurer that is committed to the GL market and has the understanding and resources to help better manage risks impacting customers.”

Last year saw a high level of mergers and acquisitions in the insurance industry. Buyers should take advantage of that disruption to re-evaluate their needs and whether their insurers are meeting them.  Or better yet, anticipating them.

What’s a Buyer to Do?

Buyers—and their brokers— should look to partner with insurers that can spot emerging trends and offer creative solutions to address them proactively.

What should buyers and brokers do, given the trends facing the GL market?

“Brokers and buyers should value insurers that have not only durability and a long history in the general liability business, but also a strong risk management infrastructure,” Perez said. “Your insurer should be able to help you mitigate your specific risks, and complement that with coverage that works for you.”

Beyond robust GL claims and legal management, Liberty Mutual also provides access to one of the insurance industry’s largest risk control departments to help improve safety and mitigate both claim frequency and severity.

In addition, notes Perez, “Even if a company has a less than optimal loss history in general liability, there can be options to provide adequate coverage for that company. The key is to partner with an insurer that has the best-in-class expertise, creativity, and flexibility to make it happen.”

By working closely with their insurers to understand trends and their potential impacts, brokers and buyers can better prepare for the possible GL storm on the horizon.
