P/C INDUSTRY NET WRITTEN PREMIUM SLIDE 4 The net written premium in this slide provides a measure of the size of each major line of business in the property/casualty (P/C) insurance industry. Every major line of business in the industry grew in net written premium volume from Calendar Year 2013 to Calendar Year 2014 Partially due to the soft reinsurance market, the fire and allied lines had only half a percentage point increase in net written premium Driven largely by the increase in carrier-estimated payroll, the workers compensation line grew more than the P/C industry as a whole, with a 4.6% increase in net written premium The increase in net written premium contributed to the industry posting another year of underwriting gains Sources National Association of Insurance Commissioners (NAIC) Annual Statement data for individual carriers prior to consolidation of affiliated carriers, including all data available as of 4/16/2015 Insurance Expense Exhibit Part II Allocation to Lines of Business Net of Reinsurance The value for the most recent year is preliminary because additional data submissions may still be received by the NAIC.

P/C INDUSTRY NET COMBINED RATIOS SLIDE 5 The calendar year combined ratios in this slide measure the overall performance of each line of business and the P/C industry as a whole, prior to the consideration of investment and other income. A combined ratio is the sum of the loss ratio, the LAE ratio, the dividend ratio, and the underwriting expense ratio. The loss, LAE, and dividend ratios are calculated as ratios to earned premium. The underwriting expense ratio is calculated as a ratio to written premium to provide a better match of the timing of the numerator and denominator. Partially due to catastrophic losses, the combined ratios for the homeowners, commercial multiple peril, and fire and allied lines increased between 2013 and 2014 In response to two consecutive years of P/C combined ratios below 100% and the slight deterioration in the combined ratio from 2013 to 2014, some have speculated that the industry has reached a turning point in the underwriting cycle Sources NAIC Annual Statement data for individual carriers prior to consolidation of affiliated carriers, including all data available as of 4/16/2015 Insurance Expense Exhibit Part II Allocation to Lines of Business Net of Reinsurance The value for the most recent year is preliminary because additional data submissions may still be received by the NAIC.

P/C INDUSTRY NET COMBINED RATIOS SLIDE 6 This slide displays a longer history of the combined ratios for the total P/C industry. See Slide 5 for more background. For the underwriting cycle beginning in 2002, the industry s average combined ratios were approximately 7 percentage points lower than those in the preceding underwriting cycle After the events of 9/11/2001, the industry s combined ratios decreased more rapidly and to a greater extent than the industry has experienced since Sources NAIC Annual Statement data for individual carriers prior to consolidation of affiliated carriers, including all data available as of 4/16/2015 Insurance Expense Exhibit Part II Allocation to Lines of Business Net of Reinsurance The value for the most recent year is preliminary because additional data submissions may still be received by the NAIC. 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 116 108 105 105 109 110 109 116 107 109 107 106 102 106 108 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014p 110 116 107 100 98 101 92 95 104 101 102 108 103 96 97 Page 4 of 63

P/C INDUSTRY INVESTMENT GAIN RATIOS SLIDE 7 The investment gain ratio includes both realized capital gains and net investment income. The investment gain ratio measures the investment performance of the P/C industry by comparing investment income to earned premium, the primary source of investment funds for insurance carriers. The largest component of the investment gain ratio, net investment income, has averaged 3 points lower post- 2001 Post-2001, even excluding the realized capital losses of 2008 and 2009, the average realized capital gain has fallen by 1.5 percentage points Carriers have shifted their underwriting strategies to adapt to the changing investment environment Sources NAIC Annual Statement data, Statement of Income: 1985 2007, 2013p 2014p ISO: 2008 2012 The value for the most recent year is preliminary because additional data submissions may still be received by the NAIC.

P/C INDUSTRY EMBEDDED YIELD REMAINS HIGHER THAN NEW MONEY YIELD SLIDE 8 Embedded Yield is the reported pretax investment income, excluding capital gains, for bond instruments held by P/C insurers divided by the asset value of those instruments. Embedded Yield is derived from accounting data as reported. It includes investment income both from (old) bonds owned at the beginning of each year and (new) bonds acquired during the year. New Money Yield is the pretax yield from the same bond portfolio (estimated on a matched type and maturity basis) as if it had been repurchased each year. The gray bars in the graph indicate periods of recession in the United States. Both Embedded and New Money Yields have declined over the last 30 years. For the first two recessions shown here, the gap between Embedded and New Money Yields (dark teal shading) widened for several years during and after the recession, and then narrowed. The yield gap for the Great Recession has been greater and more prolonged than the yield gaps for the previous two recessions. Since 2012, the Great Recession s yield gap appears to be narrowing.

P/C INDUSTRY AFTER-TAX RETURN ON SURPLUS SLIDE 9 The after-tax return on surplus compares net income generated from all sources to policyholder surplus. Since surplus varies throughout the year as income is earned, the return is calculated as the ratio of net income to the average of the surplus at the beginning of the year and end of the year. The return on surplus tends to follow the ebb and flow of the underwriting cycle. Under the assumption that the industry generates an after-tax return on surplus that is appropriate over the long term to cover its cost of capital, it is reasonable to conclude that the 8.4% after-tax return in Calendar Year 2014 is a fair return, especially considering the low-interest-rate environment The latest year s after-tax return on surplus is consistent with the long-term average shown Sources NAIC Annual Statement data, Statement of Income: 1985 2007, 2013p 2014p ISO: 2008 2012 The value for the most recent year is preliminary because additional data submissions may still be received by the NAIC. 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2.8 15.1 13.9 13.4 9.7 8.0 9.5 3.6 11.2 5.8 9.7 10.1 13.1 9.6 6.6 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014p 6.3 2.3 3.2 9.5 10.6 11.4 14.4 12.7 0.6 5.9 6.6 3.5 6.1 10.2 8.4 Page 9 of 63

P/C INDUSTRY PREMIUM-TO-SURPLUS RATIOS SLIDE 10 The premium-to-surplus ratio is one measure that can be used to help determine whether there is sufficient policyholder surplus to support the P/C insurance industry s writings. The favorable ratio of 0.74:1 in Calendar Year 2014 implies a well-capitalized market Contributions to surplus were approximately $21 billion in Calendar Year 2014, or approximately one-third of the 2013 contributions, with the largest decrease occurring in unrealized capital gains With few exceptions, surplus has increased every year since 1985 Sources NAIC Annual Statement data, Statement of Income: 1985 2007, 2013p 2014p ISO: 2008 2012 The value for the most recent year is preliminary because additional data submissions may still be received by the NAIC.

WC NET WRITTEN PREMIUM GROWTH SLIDE 12 This slide exhibits workers compensation (WC) net written premium by year, separately for private carriers and state funds. In the context of the State of the Line presentation, NCCI s definition of state funds includes only those carriers that are exempt from paying federal income taxes. All other carriers are included in the private carrier values. For state funds, net written premium in 2014 grew by $800 million, more than half of which is attributable to the California state fund NCCI estimated an increase of 5.9% in total premium to $44.2 billion 2014 marks the fourth consecutive year of workers compensation premium volume increases Sources NAIC Annual Statement data, including all data available as of 4/16/2015 Insurance Expense Exhibit Part II Allocation to Lines of Business Net of Reinsurance The value for the most recent year is preliminary because additional data submissions may still be received by the NAIC.

WC LAE TO LOSS RATIOS SLIDE 16 While taking net incurred LAE as a ratio to net earned premium provides the contribution of LAE to the overall combined ratio, LAE as a ratio to loss may be a more meaningful measure of the effort that it takes to manage and settle claims. The LAE-to-loss ratios have more year-to-year variation than the LAE-to-premium ratios. Defense and Cost Containment Expense was the driver of the increase in the LAE-to-loss ratio in 2014 while the ratio of Adjusting and Other Expense to loss remained relatively flat. California contributed to the increase in the countrywide LAE ratio because the Workers Compensation Insurance Rating Bureau of California observed an increase in LAE following the enactment of Senate Bill 863.

WC UNDERWRITING EXPENSE RATIOS SLIDE 17 The underwriting expense ratio compares the costs associated with writing insurance to net written premium. The underwriting expenses included in the ratio are: Commission and Brokerage Expenses Taxes, Licenses, and Fees Other Acquisition Expenses General Expenses Key Takeaway The underwriting expense ratio fell by 1 point from 25 to 24. The main driver of the decrease in the ratio was the increase in net written premium, rather than a decrease in expenses.

WC IGIT RATIOS SLIDE 19 The overall investment gain is allocated by line of business according to the NAIC-prescribed allocation procedure. The WC Investment Gain on Insurance Transactions (IGIT) ratio measures investment performance by comparing investment income allocated to the WC line to WC earned premium. There was a general downward trend in investment gain from 2010 to 2014. The 2014 IGIT for workers compensation was 12%, the lowest in five years.

WC IGIT RATIOS: MOVING AVERAGE SLIDE 20 Since investment gains can be volatile and lead to conclusions based on single-year observations that may not be pertinent to long-tailed lines of business, this slide shows five-year moving averages of the IGIT ratios shown on Slide 19. See Slide 19 for more background. Key Takeaway Given the embedded yield in the industry s portfolio and the downward trend in the investment gain on insurance transactions in recent years, short-term improvement in these numbers is not anticipated.

WC PRETAX OPERATING GAIN RATIOS SLIDE 23 The pretax operating gain ratios of private carriers and state funds are compared. See Slide 21 for more background. The state funds had a 5% operating gain 9 points lower than that for the private carriers. The 17-point difference in the combined ratio is now only a 9-point difference in pretax operating gain ratio. State funds typically have a much larger contribution from investment income to their operating results due to their significantly higher reserve-to-premium ratios.

WC NET COMBINED RATIOS SLIDE 25 The net combined ratios are the sum of the net incurred loss and LAE ratio, the dividend ratio, and the underwriting expense ratio. In this slide, the overall private carrier workers compensation combined ratios are shown for the most recent 10 years on both calendar year (CY) and accident year (AY) bases. The AY combined ratio reflects the experience of accidents that occurred in that calendar year. Unlike the CY combined ratio, AY combined ratios are not influenced by changes in reserves for prior AYs. See Slide 5 for more background. Compared with 2013, both the 2014 CY and AY net combined ratios improved. A 3-point improvement on a CY basis and a 4-point improvement on an AY basis were observed. The 2014 CY net combined ratio was higher than the 2014 AY value due to carrier reserve strengthening on prior accident years.

WC LOSS AND LAE NET RESERVE DEFICIENCIES SLIDE 26 The net reserve deficiency is the dollar difference (in billions) between NCCI s estimate of net loss and LAE reserves and net reserves as reported by private carriers in the NAIC Annual Statement, Schedule P, Part 1D. The overall workers compensation net reserve deficiency is calculated for all accident years combined at each year-end valuation. The net reserve deficiency decreased from $11B to $10B between year-ends 2013 and 2014. These values include tabular discounts from lifetime pension cases. The year-end 2014 net reserve deficiency is 8% of net reported reserves compared with 33% of net reported reserves at year-end 2001.

WC NET LOSS AND LAE RATIOS NCCI ULTIMATE ACCIDENT YEAR SELECTIONS VS. AS REPORTED SLIDE 27 The accident year (AY) net incurred loss and LAE ratio is calculated as a ratio of AY net losses and LAE to CY earned premium. The values in this slide reflect ultimate loss and LAE ratios estimated by NCCI compared with loss and LAE ratios reported at the latest evaluation by private carriers in the NAIC Annual Statement, Schedule P, Part 1D. NCCI s estimates reflect some level of net reserve deficiency for every year through 2011, as NCCI s estimated net incurred loss and LAE ratios are higher than the net incurred loss and LAE ratios reported by private carriers in Schedule P. NCCI s estimate for AY 2014 is 70%, whereas that reported by the industry is 73% indicating an estimated 3-point redundancy. Similarly, NCCI s estimate for AY 2013 is 73%, whereas that reported by the industry is 74% indicating a 1-point redundancy. The total $10B net reserve deficiency as of year-end 2014 shown on the previous slide is comprised of redundancies in the most recent two accident years, which are more than offset by reserve deficiencies in Years 2011 and prior.

WC NET LOSS AND LAE RATIOS ACCIDENT YEAR AS REPORTED SLIDE 28 The net incurred loss and LAE ratio is calculated as the ratio of incurred losses and LAE to earned premium. In contrast to calendar year ratios, accident year net incurred loss and LAE ratios change over time as the reserves on claims are reevaluated from one report to the next. A 73% net incurred loss and LAE ratio was originally reported for AY 2005, and subsequent reserve reductions have contributed to its year-end 2014 value of 61%. As AY 2005, 2006, and 2007 have developed favorably over time, they have revealed redundancies in the initially reported net loss and LAE reserves for these years. The industry has used those reserves to work off the large reserve deficiencies it had accumulated on prior accident years. The more recent accident years have shown comparatively greater stability between the respective values observed at first report and those as of year-end 2014.

US EMPLOYMENT LEVELS SLIDE 33 Several economic indicators are indexed to 2007, just before the onset of the Great Recession. Beginning at the top right, the indexes for both Payroll and Gross Domestic Product (GDP) surpassed their prerecession level in 2011. In 2014, for the first time since the Great Recession, employment exceeded its prerecession level by 1%. Manufacturing and construction employment are still well below their prerecession levels. Weak demand for new single-family housing has hampered recovery in the construction sector, while the manufacturing industry continues to suffer from reduced overseas demand as a result of a weak global economy and a strong US dollar. This is significant for the workers compensation industry because these two sectors accounted for about 40% of the industry s prerecession premium volume.

WC APPROVED CHANGES IN BUREAU PREMIUM LEVEL SLIDE 34 Bureau premium level changes are countrywide approved changes in advisory rates, loss costs, assigned risk rates, and rating values as filed by the applicable rating organization. The changes by state are weighted using calendar year written premium as reported to the NAIC. System reforms and reductions in claim frequency drove many of the decreases shown on the slide. Reforms leading to a reduction in rate level do not necessarily mean that benefits to injured workers are reduced. Cost containment measures, such as limits on reimbursements to medical providers and attorneys, result in lower system costs and lower rates.

WC LOST-TIME CLAIM FREQUENCY SLIDE 43 The change in lost-time claims per million dollars of pure premium includes data for all states in which NCCI provides ratemaking services, except West Virginia. Premium is developed to an ultimate basis and adjusted to current wage and voluntary pure premium level. Accident Years 2013 and prior are valued as of 12/31/2013. Accident Year 2014 is based on preliminary data valued as of 12/31/2014. Accident Years 2010 and 2011 show adjusted values, primarily due to significant changes in audit activity. Key Takeaway NCCI estimates a 2% claim frequency change between Accident Years 2013 and 2014. This is comparatively less than the annual decreases observed in 2012 and 2013 and less than the long-term average decrease of 3.7%.

WC LOST-TIME CLAIM FREQUENCY CHANGES BY TOTAL SIZE OF LOSS SLIDE 44 Exposure Accident Year frequency is calculated as a ratio of undeveloped lost-time claims at first report to premium adjusted to current wage and average carrier rate level. Individual claim amounts were adjusted to the current inflation level prior to being assigned to a size category. Lost-time claims less than $10,000 were defined as small, and those above $10,000 were defined as large. The 2009 frequency levels for each size range are indexed to 1.00 to better illustrate the changes by size over the time period shown. After the most recent recession, small claims reentered the workers compensation system at a relatively faster pace than large claims. In 2010, small claim frequency increased by 7% while large claim frequency increased by 4%. Both loss groups have experienced similar changes in claim frequency after 2010.

WC RESIDUAL MARKET POOL COMBINED RATIO SLIDE 56 The residual market combined ratios displayed on this slide reflect projected ultimate losses, servicing carrier allowance, producer fees, and other pool and plan administration expenses as a ratio to ultimate premium plus pool interest income on cash flow for all NCCI-serviced residual market pool states. The results are calculated by policy year (PY), which allows a direct match between premium earned and claims incurred for a given block of policies. PY combined ratios can change over time as new claims are reported and the reserves on existing claims are reevaluated. The estimated combined ratio for Policy Year 2014 has remained stable at 106%. Primarily driven by the increase in premium, this represents an 8% improvement since 2011. The residual market combined ratios have been stable since the early 1990s.
