Florida Litigation Market Dynamics 6 Insurers paid $15.3B in connection to lawsuits from 2013 to 2020 • 71% of payments have funded plaintiff attorney fees • One-way attorney fee statute has been the driver of frivolous suits • Attempts at legislative reform continue to fall short Litigation Trends Continued to Create a Challenging Operating Environment in Q1 Source: Guy Carpenter UPC per month suits continuing to grow since Hurricane Irma Industry Trend UPC Trend

Florida Legislative Update 7 SB 76 & 1598 Expected to Become Law July 1st & Provides Much Needed Relief Highlights Include: • Reducing the time limit for filing insurance claims to two years from the date of loss • Requiring plaintiffs to go thru several additional steps prior to filing a lawsuit on a property insurance claim • Replacing the one-way attorney fee statute with a statute that makes the recovery of attorney fees and costs contingent on obtaining a judgement for indemnity that exceeds the pre-suit offer made by the insurance company: In the event of a trial, the bill requires the plaintiff to obtain a damage award (excluding attorney fees and costs) of at least 50% of the “disputed amount” (the difference between the offered indemnity payment and the indemnity amount demanded) in order to be entitled to 100% of reasonable attorney fees. A recovery of less than 20% of the disputed amount result in no fee recovery by the plaintiff attorney. Recoveries of between 20% and 50% result in a proportionate recovery of attorney fees and costs. • Requiring the consolidation of legal actions involving coverage for multiple claims under the same residential insurance policy • Prohibits roofing contractors or any person acting on their behalf from making a “prohibited advertisement”. A “prohibited advertisement” includes any electronic communication, phone call, or document that solicits a claim, offers anything of value for performing a roof inspection, offers to interpret a policy of insurance, offers help in filing an insurance claim, or offers to adjust a claim on the insured’s behalf • Requiring public adjuster firms to be licensed by the State of Florida • Prohibits public adjusters from being paid by contractors or attorneys
