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.

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.”

Commercial Auto Warning: Emerging Frequency and Severity Trends Threaten Policyholders

Commercial auto policyholders should consider utilizing a consultative approach and tools to better manage their transportation exposures.
By: | June 1, 2016 • 6 min read

The slow but steady climb out of the Great Recession means businesses can finally transition out of survival mode and set their sights on growth and expansion.

The construction, retail and energy sectors in particular are enjoying an influx of business — but getting back on their feet doesn’t come free of challenges.

Increasingly, expensive commercial auto losses hamper the upward trend. From 2012 to 2015, auto loss costs increased a cumulative 20 percent, according to the Insurance Services Office.

“Since the recession ended, commercial auto losses have challenged businesses trying to grow,” said David Blessing, SVP and Chief Underwriting Officer for National Insurance Casualty at Liberty Mutual Insurance. “As the economy improves and businesses expand, it means there are more vehicles on the road covering more miles. That is pushing up the frequency of auto accidents.”

For companies with transportation exposure, costly auto losses can hinder continued growth. Buyers who partner closely with their insurance brokers and carriers to understand these risks – and the consultative support and tools available to manage them – are better positioned to protect their employees, fleets, and businesses.

Liberty Mutual’s David Blessing discusses key challenges in the commercial auto market.

More Accidents, More Dollars

Rising claims costs typically stem from either increased frequency or severity — but in the case of commercial auto, it’s both. This presents risk managers with the unique challenge of blunting a double-edged sword.

Cumulative miles driven in February, 2016, were up 5.6 percent compared to February, 2015, Blessing said. Unfortunately, inexperienced drivers are at the helm for a good portion of those miles.

A severe shortage of experienced commercial drivers — nearing 50,000 by the end of 2015, according to the American Trucking Association — means a limited pool to choose from. Drivers completing unfamiliar routes or lacking practice behind the wheel translate into more accidents, but companies facing intense competition for experienced drivers with good driving records may be tempted to let risk management best practices slip, like proper driver screening and training.

Distracted driving, whether it’s as a result of using a phone, eating, or reading directions, is another factor contributing to the number of accidents on the road. Recent findings from the National Safety Council indicate that as much as 27% of crashes involved drivers talking or texting on cell phones.

The factors driving increased frequency in the commercial auto market.

In addition to increased frequency, a variety of other factors are driving up claim severity, resulting in higher payments for both bodily injury and property damage.

Treating those injured in a commercial auto accident is more expensive than ever as medical costs rise at a faster rate than the overall Consumer Price Index.

“Medical inflation continues to go up by about three percent, whereas the core CPI is closer to two percent,” Blessing said.

Changing physical medicine fee schedules in some states also drive up commercial auto claim costs. California, for example, increased the cost of physical medicine by 38 percent over the past two years and will increase it by a total of 64 percent by the end of 2017.

And then there is the cost of repairing and replacing damaged vehicles.

“There are a lot of new vehicles on the road, and those cost more to repair and replace,” Blessing said. “In the last few years, heavy truck sales have increased at double digit rates — 15 percent in 2014, followed by an additional 11 percent in 2015.”

The impact is seen in the industry-wide combined ratio for commercial auto coverage, which per Conning, increased from 103 in 2014 to 105 for 2015, and is forecast to grow to nearly 110 by 2018.

None of these trends show signs of slowing or reversing, especially as the advent of driverless technology introduces its own risks and makes new vehicles all the more valuable. Now is the time to reign in auto exposure, before the cost of claims balloons even further.

The factors driving up commercial auto claims severity.

Data Opens Window to Driver Behavior

To better manage the total cost of commercial auto insurance, Blessing believes risk management should focus on the driver, not just the vehicle. In this journey, fleet telematics data plays a key role, unlocking insight on the driver behavior that contributes to accidents.

“Roughly half of large fleets have telematics built into their trucks,” Blessing said. “Traditionally, they are used to improve business performance by managing maintenance and routing to better control fuel costs. But we see opportunity there to improve driver performance, and so do risk managers.”

Liberty Mutual’s Managing Vital Driver Performance tool helps clients parse through data provided by telematics vendors and apply it toward cultivating safer driving habits.

“Risk managers can get overwhelmed with all of the data coming out of telematics. They may not know how to set the right parameters, or they get too many alerts from the provider,” Blessing said.

“We can help take that data and turn it into a concrete plan of action the customer can use to build a better risk management program by monitoring driver behavior, identifying the root causes of poor driving performance and developing training and other approaches to improve performance.”

Actions risk managers can take to better manage commercial auto frequency and severity trends.

Rather than focusing on the vehicle, the Managing Vital Driver Performance tool focuses on the driver, looking for indicators of aggressive driving that may lead to accidents, such as speeding, sharp turns and hard or sudden braking.

The tool helps a risk manager see if drivers consistently exhibit any of these behaviors, and take actions to improve driving performance before an accident happens. Liberty’s risk control consultants can also interview drivers to drill deeper into the data and find out what causes those behaviors in the first place.

Sometimes patterns of unsafe driving reveal issues at the management level.

“Our behavior-based program is also for supervisors and managers, not just drivers,” Blessing said. “This is where we help them set the tone and expectations with their drivers.”

For example, if data analysis and interviews reveal that fatigue factors into poor driving performance, management can identify ways to address that fatigue, including changing assigned work levels and requirements.  Are drivers expected to make too many deliveries in a single shift, or are they required to interact with dispatch while driving?

“Management support of safety is so important, and work levels and expectations should be realistic,” Blessing said.

A Consultative Approach

In addition to its Managing Vital Driver Performance tool, Liberty’s team of risk control consultants helps commercial auto policyholders establish screening criteria for new drivers, creating a “driver scorecard” to reflect a potential new hire’s driving record, any Motor Vehicle Reports, years of experience, and familiarity with the type of vehicle that a company uses.

“Our whole approach is consultative,” Blessing said. “We probe and listen and try to understand a client’s strengths and challenges, and then make recommendations to help them establish the best practices they need.”

“With our approach and tools, we do something no one else in the industry does, which is perform the root cause analysis to help prevent accidents, better protecting a commercial auto policyholder’s employees and bottom line.”
