2. 1 State of the Primary Casualty Market  Insured's with good credit ratings, effective risk management programs and favorable loss experience are averaging flat to -5% rate reductions  In general, retentions have not retreated, however with the soft market coupled with an excellent loss record, clients should constantly review options for decreased loss retention levels  General Liability –Rates on risks with good loss experience are decreasing but significant exposure decreases may reduce the ability to further cut rate.  Financial responsibility (fronting) –Very competitive particularly in competitive bidding situations  Workers’ Compensation (US) –Expect to see rate decreases ranging from flat to -5% as a result of competition and favorable statutory changes  Risk transfer rates above client loss retentions for WC, GL and Auto continue to decrease through the third quarter

4. 3 State of the Umbrella/Excess Market Pricing  Beginning in 2009, rate reductions between -5% to -10% were replaced with rate reductions in the range of -2% to -4% remaining in that range through the 3rd quarter of 2010. –Markets have historically been aggressive to close out the 4 th quarter on new business growth  Excess capacity carriers are strictly adhering to minimum premiums  Overall lead and excess layer pricing continues to be competitive but is certainly stabilizing  In 2011, most Insured's will see further premium reductions either due to reduced exposures or rate reductions

5. 4 State of the Umbrella/Excess Market Capacity  Excess capacity has grown significantly in 2008/2009/2010  Currently, there is approximately $2 billion of total available capacity
