How can you identify natural catastrophe risks?
Strategic natural catastrophe risk consultancy
To help you both identify and quantify the hazards you face, our natural catastrophe risk consultants carry out in-depth risk analysis, hazard and catastrophe modeling, vulnerability assessments, as well as catastrophe engineering loss assessments.
Natural catastrophe and climate analytics
Climate Diagnostic identifies and helps you visualize how changes in acute hazards, such as extreme wind and flood, and chronic stress factors, including sea-level rise and heat stress, could impact your properties.
Global Peril Diagnostic shows your organization’s exposure to natural catastrophe and other perils, generating site-specific hazard scores. It also gives you live event tracking and alerts on the latest natural catastrophe threats.
How can you quantify natural catastrophe risks?
Property Quantified
Property Quantified models potential losses from natural catastrophe perils based on engineering reports, loss history and nat cat loss drivers. You can quantify losses by peril, geography and location and analyze your insurance options, laying the foundations for more informed and efficient risk transfer.
Natural catastrophe forensic accounting and valuations services
Optimize the cost of insuring against nat cat perils with our global team of forensic accountants, appraisers and surveyors. Our Forensic Accounting and Valuations Services help deliver more value from pre-loss insurance valuations to post-loss quantification of damage.
How can you mitigate natural catastrophe risks?
Natural catastrophe strategic risk consultancy
Armed with data-driven insight and cost-benefit analysis tailored to your organization, our nat cat strategic risk consultants reveal and implement more effective and efficient mitigation, risk management and risk transfer options.
Natural catastrophe risk engineering
Our multidisciplinary team carries out natural catastrophe risk engineering loss evaluations for critical sites, conducting rigorous on-site inspections and remote desktop evaluations to produce comprehensive probable maximum loss (PML) assessments.
From planning through to construction and operation, we give you a decision-making framework around nat cat hazard and climate-resilient design for both your existing and future assets.
We can identify the most urgent non-insurance risk mitigation controls, develop business continuity plans, recovery plans and crisis management readiness.
How can you transfer nat cat risks?
Insurance and facultative reinsurance for natural catastrophe
We combine global reach and local knowledge to find the most appropriate placement for your natural catastrophe risks, either as standalone cover for individual perils or as part of a global property program.
We also support more effective and efficient programs by helping to reinsure individual layers of risk through our Facultative Reinsurance and Structured Risk teams.
Innovative natural catastrophe insurance solutions
Get tailor-made risk financing solutions to help close your natural catastrophe protection gaps and offer more efficient ways to deploy capital.
Our Alternative Risk Transfer (ART) and Financing team provide a range of insurance solutions to complement or replace traditional insurance when it may not be wholly suitable.
These include parametric solutions for specific weather or natural catastrophe risks, which offer rapid payouts should an event reach a certain magnitude according to a pre-agreed measurement or formula.
Our scientific approach to natural catastrophe risks
We apply a science-based approach to natural catastrophe model evaluation, data quality and proactively keep you on top of changing nat cat risks with globally-recognized research.
Natural catastrophe research and innovation: Willis Research Network
To help you better understand and manage emerging natural catastrophe, complex and inter-related risks, Willis Research Network (WRN) works with more than 50 partner institutions worldwide, including leading universities, think tanks, national labs and specialized research centers.
WRN connects cutting-edge science with commercial decision-making by applying scientific thinking to understand natural catastrophe risk management, risk modeling and resilience planning.
It also publishes our Natural Catastrophe Review to provide insight into recent natural catastrophes and share expert views on the risks posed by major perils.
More informed insurance decisions with natural catastrophe model evaluation
To help you develop your own view on your risks and make more efficient insurance in light of your vulnerabilities and potential financial losses, we can evaluate your natural catastrophe models.
Enhancing data quality for better natural catastrophe insurance outcomes
Improve the quality of information in your organization’s schedule of values with our data cleansing service. We can enhance the quality of geolocation data and building characteristic codes, clarifying how values are apportioned between buildings, contents and business interruption in support of better insurance outcomes.
