Guy Carpenter report shows insurance industry continuing to release reserves through 2014

Homeowners and Private Passenger Auto Lines Exert Greatest Impact on Reserve Cycle

New York, NY (May 5, 2014) – Guy Carpenter & Company, LLC, the leading global risk and
reinsurance specialist and member of Marsh & McLennan Companies, has released an updated analysis of industry reserves.

Based on 2013 annual statutory statements, Guy Carpenter has updated their analysis of the reserve
cycle by examining accident year data for eleven lines of business. According to the analysis,
workers compensation reserves appear to be improving, despite noted deterioration over the last
year. Similarly, medical professional liability and commercial multi-peril lines appear to be making
tentative turns to show greater reserve release in accident year 2012 than expected. Conversely,
other lines such as commercial auto liability continued to exhibit deterioration.

“Guy Carpenter looks at the reserve cycle differently, by studying reserve movements by accident
year, rather than financial year,” said Jessica Leong, Lead Casualty Specialty Actuary. “By analyzing
the cycle the same way actuaries do – by accident year – the trends are clearer. We can help our
clients better understand the drivers of the cycle and navigate through it. According to our analysis,
accident year 2013 shows more releases than accident year 2012, not less, as we had been

A major driver of the continued release of reserves can be attributed to homeowners and private
passenger auto lines, which are responsible for 70 percent of the improvement for accident year
2012. However, there is a lack of a clear cycle for short tailed lines, which makes it challenging to
predict whether accident year 2013 will continue to show releases in 2014.

“The somewhat random movement of the reserve cycle for short tailed lines of business, such as
homeowners and private passenger auto lines, makes it harder to predict what the future holds for
the 2013 accident year,” said Leong. “However, long tailed lines such as workers compensation,
medical professional liability and commercial multi-peril, also released more reserves for accident
year 2012 than for accident year 2011. That is much more interesting, since these long tailed liability
lines are very cyclical.”
