3 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the 1 Introduction This report was prepared by (Oliver Wyman), actuarial consultants to the (Board). This report presents our analysis of Industry-wide private passenger automobile premium and loss experience in Alberta that will be considered by the Board in deciding on the annual Industry-wide rate level adjustment to become effective on November 1, The scope of the analysis is limited to the Basic Coverages: Third Party Liability (TPL) and Benefits. Data and Reliances The data utilized in this study and presented in this report is based on information published by the General Insurance Statistical Agency (GISA) that has been compiled by the Insurance Bureau of Canada (IBC). We have not audited, verified, or reviewed this data for reasonableness, accuracy, or consistency, as it is outside the scope of our study. In the event material errors are found in this data, our findings may need to be revised. We also considered the findings presented in the report prepared by KPMG LLP (KPMG) dated December 13, 2004 for Alberta Finance. This report provides estimates of the loss cost changes resulting from the reforms under Bill 53. Oliver Wyman 1

4 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the Limitations The assumptions and judgments we have made in selecting the factors, provisions, and methodology that we present in this report for the Board s consideration in deciding upon the Industry-wide rate level adjustment to become effective on November 1, 2007 are based on data and information made available to us at the time of this analysis. Our assumptions, judgments, and selections are subject to uncertainty as is inherent in any loss forecast. Our analysis and findings are for the insurance industry as a whole, including the Facility Association (FA), and the two Risk Sharing Pools (RSPs), and may not be appropriate for an individual insurance company whose portfolio of risks, rates, expenses, and operating characteristics may differ from the insurance industry averages that underlie our findings. Oliver Wyman 2

5 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the 2 Summary of Findings In this report we present for the Board s consideration: an analysis and discussion of the key assumptions to be made and factors and provisions to be selected to derive an estimate of the required average premium for the policy year effective November 1, 2007; a methodology for applying selected assumptions, factors, and provisions to derive an estimate of the required average premium for the policy year effective November 1, 2007; and an estimate of the average street premium. The percentage difference between the estimated required average premium and the average street premium represents the indicated Industry-wide rate level adjustment for the policy year effective November 1, The analysis that we present is of Industry-wide loss (claim) and expense experience in Alberta over recent past years, including a review of the experience that has emerged thus far under the reform measures that became effective in We consider Industry claim experience through December 31, Oliver Wyman 3

6 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the The methodology we present to calculate the estimated required average premium essentially follows the methodology we presented in our reports to the Board for the November 2005 and November 2006 Industry-wide rate level adjustments. We estimate the average street premium for the policy year effective November 1, 2007 based on (1) our analysis of Industry-wide premium experience in Alberta during the second half of 2006, (2) adjustments we make to that experience to reflect the premium adjustments ordered by the Government, (3) rate changes approved for individual insurers by the Board, and (4) fast-track data reported by insurers to IBC for the first three months of In the analysis that we present in this report we provide the Board with the assumptions, factors, and provisions that we recommend the Board use to determine the required average premium and, hence, the Industry-wide rate level adjustment. But the projection of future rate needs is subject to uncertainty. This is particularly the case at this time given the relatively short time span that has elapsed since the implementation of the reform measures. For this reason, in presenting the assumptions, factors, and provisions we select, we provide rationale for our selections as well as information to help the Board evaluate the reasonableness of other selections. We also suggest that the Board consider additional information provided by other interested parties that may be more current (i.e., perhaps through May 31, 2007) or that may provide further insight into the private passenger automobile Basic Coverage loss experience that has emerged or is expected to emerge. However, in doing so the Board should also consider that the experience of one party may not be representative of the experience of the Industry. The Board should also recognize that while it may be that, alone, an alternative assumption, factor, or provision may be reasonable, combining alternative assumptions, factors, or provisions may not produce a reasonable estimate of the required average premium.

7 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the 3 Recent Legislative Reforms and Government Actions In 2003 the Alberta Government enacted Bill 53, which provided for: a cap on pain and suffering for minor injuries at $4,000 1 ; the consideration of collateral sources; the determination of wage loss based on net, rather than gross wages; and the increase of medical/rehabilitation benefits under Benefits to $50,000 maximum 2 diagnosis and treatment protocol fees for medical/rehabilitation benefits under Benefits. These reforms became effective October 1, 2004, with the exception of the consideration of collateral sources and the determination of wage loss based on net rather than gross wages, which became effective January 26, The Government also ordered premiums to be frozen on October 30, On October 1, 2004, the Government introduced the Grid Rate System, which set maximum premiums to be charged for the Basic Coverages, and established two Risk Sharing Pools (RSPs) under a take all comers underwriting system. In addition, 1 The $4,000 limit was increased to $4,144 effective January 1, Maximum fees have increased since the initial effective date of Bill 53. Oliver Wyman 5

8 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the premiums were ordered to be rolled back, and policyholders received a 5% reduction in their premiums for the remainder of their policy terms. In April 2005, the Government mandated a rate reduction in the Basic Coverages of at least 6% by July 1, This reduction did not apply to the Grid rates. On October 7, 2004, the Alberta Court of Appeal ruled that Section 8 of the Fatal s Act discriminated on the basis of age and marital status and struck the words referring to age and marital status. This decision effectively removed the marital status requirement from the Act (the Act had been amended in 2002 to remove the age requirement). The Industry-wide rate level adjustment effective November 1, 2005 was a 4% reduction for Basic Coverages. The reduction in the Grid rates amounted to 1.6% after required adjustments to the territorial relativities. The Industry-wide rate level adjustment effective November 1, 2006 was a 3% reduction for Basic Coverages. The reduction in the Grid rates amounted to 1.2% after required adjustments to the territorial relativities. Effective March 1, 2007, the Government revised the accident benefits coverage limits as follows: (1) increased the funeral benefits from $2,000 to $5,000 and (2) increased the maximum weekly disability income limit from $300 to $400 for employed individuals and from $100 to $135 for other individuals. Oliver Wyman 6

9 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the 4 Analysis & Discussion General The indicated Industry-wide rate level adjustment for the policy year effective November 1, 2007 is the percentage difference between the estimated Industry-wide average street premium and the estimated required Industry-wide average premium. In this section we present: an analysis and discussion of the key assumptions to be made and factors and provisions to be selected to derive an estimate of the required average premium for the policy year effective November 1, 2007; a methodology, or framework, for applying the selected assumptions, factors, and provisions to derive an estimate of the required average premium for the policy year effective November 1, 2007; and an estimate of the average street premium. In so doing we provide the Board with the assumptions, factors, and provisions that we recommend the Board use to determine the required average premium and, hence, the Industry-wide rate level adjustment. But the projection of future rate needs is subject to uncertainty. Therefore, in presenting the assumptions, factors, and provisions we select, we provide rationale for our selections as well as information to help the Board evaluate the reasonableness of other selections. Oliver Wyman 7

10 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the Required Average Premium The required average premium is estimated by separately estimating needed provisions for claim cost, insurance company operating expenses, the health services levy, and insurance company profit, and by giving consideration to investment income expected to be earned on the insurance underwriting operation cash flow. We discuss below the key assumptions that must be made and the factors and provisions that must be selected to derive an actuarial estimate of the required average premium. Claim Cost The source for the claim data that we analyze is the Industry AIX Automobile Exhibit (as of December 31, 2006) provided by GISA, and it includes the experience of all drivers in the province, including the Facility Association and the two RSPs (from the time they were formed). Estimating Losses and Claim Counts by Year We develop the Industry-wide reported incurred losses and claim counts for accident years 2002 to 2006 to an ultimate level using the AIX Industry Alberta accident half-year reported incurred loss and allocated loss adjustment expense (ALAE) and claim count data as the basis for our selected loss development factors. We apply the Incurred Loss Method to losses and the Reported Claim Method to claim counts. Generally (exceptions discussed below), we select the weighted average of the last six development factors, adjusted, when appropriate, to reflect seasonality evident in the 6 to 12 month development period, as we consider this selection to be a reasonable balance between responsiveness and stability. However, as we stated in our report to the Board last year, We observe there to be a general decline in the Bodily Injury and Benefits-Medical/Rehabilitation incurred loss development factors for the 6-12 month, month and month Oliver Wyman 8

11 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the development periods. In our analysis last year, we selected the weighted average of the last six development factors because, as we stated, we are uncertain whether this [decline] represents a change in the loss development pattern. Therefore, we make no adjustments to our selection process. In this analysis, we observe there to be a continued general decline in the Bodily Injury, and to a lesser extent the Benefits-Medical/Rehabilitation, incurred loss development factors for the incremental development periods up to 24 months. We, therefore, select the weighted average of the last two development factors up to 24 months of development. In contrast to this decline in the Bodily Injury incurred loss development factors for the incremental development periods up to 24 months, we notice, in general, a small upturn in the development factors during the 24 to 60 month development periods. Based on our review of the historical ratio of paid to incurred losses for Bodily Injury, it appears that a higher percentage of incurred losses is unpaid during the 24 to 60 month development periods. Based on our judgment, we select the weighted average of the last two development factors and increase our selected incurred loss development factor at the 36 to 42 month interval to reflect this changing pattern. We observe a general increase in the Bodily Injury and Benefits- Medical/Rehabilitation reported claim count development factors, and consistent with our selection of incurred loss development factors we have selected the weighted average of the last two development factors for the incremental periods up to 60 months. We note that the selection of development factors has an effect on other key assumptions, factors, and provisions (such as loss trend and the effect of the reform measures). GISA advised the Industry in its notes to the AIX statistical data exhibits of claim count reporting errors and changes in reserving protocols by a couple of major insurers. Our reliance upon the average of the latest two development factors for the longer-tail coverages should minimize the impact of the error correction and changes in reserving practices; nevertheless these changes do add an additional degree of uncertainty to the analysis, which the Board may wish to consider. Oliver Wyman 9

12 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the Loss Trend To derive estimates of appropriate loss trend rates and the cost effects of the reform measures, we perform a regression analysis, using a model we developed, on the estimates of the Industry-wide Alberta ultimate incurred loss and ALAE claim severity (including a provision for unallocated loss adjustment expenses), claim frequency, and loss cost by accident year that we derive. We consider the accident half-years spanning the period to , and perform our regression analysis by sub-coverage. In doing so, we reflect several parameters that could have an impact on the trends: time, seasonality, the Bill 53 reform measures and an additional parameter we introduced last year that we call frequency adjustment. In selecting loss trend rates and the effects of the reform measures, we consider: statistical significance of each parameter; variance in results based on different historical time periods selected; interdependence of frequency and severity trend patterns; and how closely the fitted values calculated by the model for each accident half year compare to the actual data based on various statistical tests. Bill 53 Parameter One difficulty that arises in determining loss trend patterns is that during the experience period there was a change in the claim experience that is attributed to the reform measures and not due to general loss trend. Therefore, the impact of the reform measures needs to be isolated and, in a sense, removed, so that the underlying loss trend pattern and the cost effects of Bill 53 can be separately identified. The Bill 53 parameter provides a means of doing so. We discuss the estimated cost effect of the reform measures that results from our model later in this report. Oliver Wyman 10

13 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the Frequency Adjustment Parameter Last year we introduced a model parameter which we called frequency adjustment as a means to measure the claim frequency rate pattern that has occurred in a more structured manner. We continue to include this frequency adjustment parameter in our regression analysis where it is statistically significant and it is graphically evident that a change in the frequency trend pattern has occurred. In applying this parameter we consider three questions: (1) When did the pattern begin of sharply declining claim frequencies begin? (2) Is the period of sharply declining claim frequencies over, and if so, when did it end? and (3) If the period of sharply declining claim frequencies is over, will the future near-term claim frequency trend pattern be as it was prior to the sharp decline, or will claim frequencies remain level over the near-term, or will claim frequencies increase, perhaps sharply, to unwind part or all of the sharp decline that has occurred? No one yet knows with certainty the answers to these questions. However, the additional twelve months of data that is now available provides greater insight into these questions. We find the frequency adjustment parameter to be statistically significant for Bodily Injury, Property Damage, and two Benefits subcoverages: Disability Income and Medical/Rehabilitation. Based on our review of the data, for this analysis we make the following assumptions as respects the claim frequency parameter. Oliver Wyman 11

Based on this information and the underlying data, we assume that the period of sharply declining claim frequencies began during the period, ended during the period , and that the near-term future claim frequency rate will follow the trend pattern that existed just prior to the beginning of the sharp decline. Oliver Wyman 13

Per Thousand Claim Frequency Per Thousand The data indicates that while the claim frequency rate has been generally declining since 1992, it began to more sharply drop in (the second half of 2002) and continued to Oliver Wyman 14

Based on this information and the underlying data, we assume that the period of sharply declining claim frequencies began in and ended in ; we assume that there was a sharp unwinding of the decline in claim frequency beginning in ; and we assume that the unwinding of the decline in the claim frequency rate will continue beyond Oliver Wyman 15

18 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the Benefits Medical/Rehabilitation The following graph displays our estimate of the actual claim frequency rate over the period through Claim Freq. Per Thousand Claim Frequency Per Thousand The data indicates a decline in the claim frequency rate over the period (the first half of 1999) through , followed by a period in which the frequency rate sharply increased (an unwinding of the claim frequency decline). Like Property Damage, this unwinding of the claim frequency decline appears to have continued through the end of Oliver Wyman 16

19 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the However, it also appears that the unwinding has been sharper than it has been for Property Damage. We further note that the claim frequency rate is now above the predecline level. Based on this information and the underlying data, we assume that the period of sharply declining claim frequencies began in and ended in ; we assume that there was a sharp unwinding of the decline in claim frequency beginning in and ending in ; and we assume that near-term claim frequency rate will follow the trend pattern that existed just prior to the beginning of the decline.

Per Thousand 3 Claim Frequency Per Thousand The data indicates a decline in the claim frequency rate that began in (the first half of 2002) and ended during , and like Bodily Injury does not provide clear evidence of an unwinding of the decline in the claim frequency rate. Oliver Wyman 18

21 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the Based on this information and the underlying data, we assume that the period of sharply declining claim frequencies began during the period ended during the period , and we assume that the near-term future claim frequency rate will follow the trend pattern that existed prior to the beginning of the sharp decline. Selection of Loss Trend Rates Bodily Injury We select loss trend rates for Bodily Injury by applying our regression model separately to claim frequency and claim severity, subject to the parameters of time, seasonality, Bill 53, and the frequency adjustment discussed in the prior section. As respects severity, we select a past severity trend rate of -1.5% and a future severity trend rate of +1.5%. Our selected past severity trend rate is based on our consideration of the different trend patterns that are evidenced over the period immediately preceding the reform change (-1.1%) and the period immediately following the reform change (-1.8%). Our selected future severity trend rates is based on a blending of (a) an observed longterm trend rate of 5.8%, reduced to approximately 4.35% to reflect the expected impact of Bill 53 (the $4,000 cap, now $4,144) and (b) our selected past severity trend rate of -1.5%. As respects frequency, our selected frequency model is based on the ten-year period spanning through subject to the parameters of time, seasonality, and the frequency adjustment discussed in the prior section. We select a past frequency trend rate of -0.9% based on the average trend over the experience period from our model. Based on this same model, we select a future frequency trend rate of 1.3%. Property Damage For Property Damage we select loss cost trend rates directly - which fully and consistently reflects the interaction between the claim frequency trend and the claim severity trend - with the parameters statistically significant for at least one of frequency, severity, and loss cost. We apply our regression model to loss costs over the ten-year Oliver Wyman 19

22 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the period spanning through (excluding the year, which we believe to be an outlier), subject to the parameters of time, seasonality, and the frequency adjustment discussed in the prior section. Our selected past trend rate of 6.0% is based on the average trend over the experience period from our model. Our selected future trend rate of 6.6% is based on this same model. Benefits Medical/Rehabilitation As we do for Property Damage, for Medical/Rehabilitation we select loss cost trend rates directly. We do so by applying our regression model to loss costs over the ten-year period spanning through subject to the parameters of time, seasonality, Bill 53, and the frequency adjustment discussed in the prior section. Our selected past trend rate of 6.9% is based on the average trend over the experience period from our model. Our selected future trend rate of 4.0% is based this same model. Benefits Disability Income For Disability Income we also select loss cost trend rates directly, and we do so by applying our regression model to loss costs over the ten-year period spanning through subject to the parameters of time, seasonality, and the frequency adjustment discussed in the prior section. Our selected past trend rate of 1.6% is based on the average trend over the experience period from our model. Our selected future trend rate of 2.8% is based on this same model. The actual data, fitted data, selected parameters and statistical results and graphs are presented in Appendix A, Exhibit 5. Oliver Wyman 20

23 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the Within our loss trend regression analysis, the 2002 to 2006 past loss costs are projected to the future average accident date of November 1, 2008 using projection factors based on the selected trends. We calculate the projection factors as the ratio of the fitted loss cost value as of November 1, 2008 to the fitted value from average accident date of July 1 for each accident year. In those cases where a Bill 53 parameter is included in the regression model, the Bill 53 parameter is removed from the projection factor (as the reform factors are applied separately to the 2002 to 2006 data, as discussed in the Cost Impact of Reform Factors section below). These projection factors are presented in Exhibit 5. The following Table 1 summarizes our selected future loss trend rates by sub-coverage compared to the future loss trend rates we presented in our two prior reports. Our selected future annual loss trend rates apply to the historical loss experience for the period after October 1, Table 1 Estimated Annual Future Loss Trend Rates Coverage Data as of December 31, 2006 Data as of December 31, 2005 Data as of December 31, 2004 TPL-Bodily Injury 2.8% 3.9% 1.5% TPL-Property Damage 6.6% 3.4% 3.1% AB-Death -0.1% 0.4% 0.5% AB-Funeral 0.2% -0.7% 0.2% AB-Medical/Rehab 4.0% 4.0% 3.8% AB-Disability Income 2.8% 2.6% -4.0% While we believe our selected trend rates to be reasonable based on the published Industry data through December 31, 2006, we acknowledge the higher than normal Oliver Wyman 21

24 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the degree of uncertainty surrounding the pattern of future trend rates and that the estimate of the required average premium is quite sensitive to the trend rates that are selected (i.e., relatively small changes in the trend rates could result in a rather significant change in the estimated required average premium). For this reason the Board should consider more current information or additional insights on claim frequency patterns that may be presented by other interested parties at the Public Meeting. Cost Impact of Reform Measures and Benefit Level Changes By including a Bill 53 parameter in our regression model to analyze loss trend, our model also provides an estimate of the impact that Bill 53 has had on Bodily Injury and Benefits-Medical/Rehabilitation claim costs. The estimate that is derived from our model is a savings for the Bodily Injury coverage and a savings for the Benefits- Medical/Rehabilitation coverage. Since we have selected our loss trend rate for Bodily Injury based upon a review of various regression models - with different time periods and parameters - we have calculated the savings on the Bodily Injury coverage based on the change in claim severity from 2003, adjusted for our assumed past severity trend rate of -1.5%, to We estimate a savings of 31.3%. This is in line with the 30.2% savings that had been estimated by KPMG, which it presented in its report to Alberta Finance dated December 13, Given the estimated 31.3% savings produced from our model is based on just two complete years of data we select as the Bodily Injury reform factor a savings of approximately 30.1%, which represents a 50%-50% weighting of the estimate from our model and the KPMG estimate (adjusted to include a 2% cost increase estimated to result from the Fatal s Act, which KPMG did not reflect in its 30.2% estimate). The Benefits Medical/Rehabilitation claim experience since the implementation of Bill 53 has been quite different from what had been estimated by KPMG. The result is that we have two very different estimates of the cost impact of Bill 53. The estimate produced by our model is a 16% cost savings while KPMG had estimated a 97.7% cost increase. Oliver Wyman 22

25 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the While it is possible that the large difference in estimates is due to the fact that the experience under Bill 53 is still limited and may not fully reflect the impact that Bill 53 will have on claim costs, we believe that the difference is too great for this to be the cause of the difference. Another, more likely (in our opinion), explanation is that KPMG s estimate is simply too high. Support for this position is found in KPMG s report: KPMG did not reflect in its estimate the limitations on certain medical services and the new treatment protocols. We therefore select as the Benefits Medical/Rehabilitation reform factor a savings in costs of approximately 16%. Effective March 1, 2007 the funeral benefit level and disability benefits levels were increased. We adjust the 2002 to 2006 loss cost data to include a provision for these higher benefit levels. In the case of the funeral benefit, we increase our estimate of the projected funeral loss cost per vehicle by a ratio of 5/2 to reflect this increased benefit from $2,000 to $5,000. In the case of disability income, we rely upon employment statistics for the Province of Alberta compiled by Statistics Canada, 2005 and the Canadian Customs Revenue Agency (CCRA) 2003 tax year data to estimate the percentage increase in loss cost for the weekly benefit increase from $300 to $400 for employed individuals and from $100 to $135 for other individuals. Based on our assumptions of collateral sources and distribution of employed versus non-employed individuals, we estimate the disability income benefits loss cost will increase by 20.4%. We estimate these higher benefits for funeral and disability income will increase the Benefits projected loss cost per car by $2.66 for the policy year effective November 1, We assume that approximately 70% of these increased benefit levels were previously recoverable under the Bodily Injury coverage and therefore estimate a $1.86 offset reduction in Bodily Injury loss costs. Loss Adjustment Expenses Allocated loss adjustment expenses (the legal expenses associated with claim settlement) are included with the reported Industry-wide loss data, so no further analysis is required. Oliver Wyman 23

26 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the The other claim settlement related expenses, or unallocated loss adjustment expenses (ULAE), are not included with the Industry-wide reported loss data; however, IBC publishes an estimated loading factor for ULAE in the AIX Exhibits: Table 2 ULAE Factors Province of Alberta Year ULAE Percentage 8.9% 9.3% 10.3% 9.7% 8.7% We use these IBC ULAE factors without adjustment in our analysis. Health Services Levy The most recent Health Services Levy assessment by the Ministry of Health and Wellness is $80 million for We assume these costs will increase at the same rate as our selected Benefits-Medical/Rehabilitation loss trend rate. Based on our estimated ratio of private passenger to all automobile Third Party Liability premiums, we determine that including a provision of approximately 5.7% of Third Party Liability premiums will meet this forecasted Health Services Levy cost. We note that should the Health Services Levy provision increase at a faster or slower rate than we have assumed, our estimates may be too low or too high. GST We adjust the loss experience for the pending change in the GST rate from 7% to 6% effective July 1, We assume that this reduced GST rate will result in a reduction in claims costs for the Property Damage and Benefits- Medical/Rehabilitation coverages and that the effect on other coverages is immaterial. Oliver Wyman 24

27 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the Year Weights We weight the estimated ultimate trended and adjusted loss costs per earned vehicle for accident years 2001 to 2005 by 5%, 10%, 15%, 30%, and 40%, respectively. These percentage weights remain unchanged from those we selected in the prior two industrywide adjustment analysis and represent what we believe to be a reasonable balance between data responsiveness (i.e., the more recent the year the more likely its experience is reflective of future conditions) and data stability. Investment Income on Cash Flow The selected provision for claim cost is adjusted (reduced) to reflect the investment income earned on the cash flows arising from the insurance operations (i.e., the premium collected before it is used to pay claim costs and other expenses). We use a model to determine the adjustment. The following assumptions underlie our model: A payment pattern based on the Alberta s Industry-wide paid loss data published in the 2005 accident half-year loss development AIX Exhibits, and our estimate of the underlying average payment pattern for each coverage. In general, we select the weighted average of the latest 6 loss development factors for each incremental period. A 90 day delay in receipt of premiums. An investment income rate of 4.3% - the average 3-Year Government of Canada Bond rate for the week ending May 18, The key assumption is the investment rate. The selection of the 3-Year Government of Canada Bond rate represents a change from the approach we have followed in the prior two Industry-wide Rate Adjustments and is based on information presented at the Profit Review Meeting that was conducted by the Board in November We provide the Board with the following updated information, as was provided in our report last year for its consideration: Oliver Wyman 25

28 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the We reviewed the P&C-1 annual financial reports of the 18 largest automobile insurers in Alberta and found the average annual investment yield rate for 2004, 2005, and 2006 was approximately 5.9%, 6.4% and 6.4%, respectively. The required average premium decreases by approximately 2.1% for a one percentage point increase in the investment yield rate. Expenses As we have done for the past two Industry-wide Rate Level Adjustment studies, we base our selected expense provision on the expense information survey conducted by IBC. Insurance companies who are members of IBC report their Alberta and Countrywide automobile detailed expense information to IBC on a voluntary basis. For last year s Industry-wide Rate Adjustment, we were provided with the survey information through the year This year we have been provided with the survey information through We note that IBC revised its expense survey since last year and that the data presented for years 2005 and 2006 is in a new format. Perhaps the most significant change is that the other expense category is now reported as a dollar amount per vehicle, as well as a percentage of premium. Another significant change is that the commission expense and contingent commission expense are now combined and are no longer displayed separately. In addition, the commission expense is now separately reported as either private passenger vehicles or all other vehicles. We also note that IBC reports the overall participation rate was approximately 80% for the 2006 survey based on direct written premium. This represents an increase over past participation levels. The following table summarizes the reported historical expense ratios for Alberta as published by IBC for 1999 to 2004 under the prior survey format. Oliver Wyman 26

30 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the A decrease in the total commission costs has led to a decrease in the reported expense ratio for 2006 (25.5%) compared to the 2005 level (26.1%). In our opinion, the total expense provision we select, 25.5%, the same as the reported expense ratio for 2006, represents a reasonable expense provision for the calculation of the Industry-wide adjustment in Alberta for the policy year beginning November 1, Our selected total expense provision of 25.5% for the policy year effective November 1, 2007 represents an increase of 2.6 percentage points over last year s selected ratio of 22.9%. Almost all of this increase comes from the other operating expenses category. We assume that the other operating expense costs, 10% of premium or $ per car (as estimated by IBC) are split 50%/50% between fixed and variable with the premium level. The 50%/50% split is consistent with the split accepted by the Board at last year s Industry-wide Rate Adjustment. We assume that 60% of these other fixed expense costs are allocated to the mandatory coverages and the balance to the additional coverages. We further assume that the fixed costs will increase at a rate of 5.5% per annum - in line with the CPI index in Alberta. Profit As directed by the Board, we select a profit provision of 5% of premium. The 5% provision is the same as that selected for the prior two Industry-wide Rate Adjustments. Methodology to Derive the Required Average Premium The required average premium is derived by combining the resulting weighted average trended ultimate loss (and loss expense) cost per earned vehicle, adjusted to reflect investment income arising from the insurance operations, with the selected provisions for health services levy, expenses, and profit. More specifically, Oliver Wyman 28

31 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the the ultimate loss per car is estimated for each of the most recent five accident years through the application of loss development factors; adjustments are made to the estimated ultimate loss per car for the accident years in order for the effects of the reform measures to be fully recognized (the adjustment for the 2004 year is a partial adjustment); the adjusted ultimate loss per car estimates are each trended to reflect the cost conditions anticipated to be in effect for the policy period spanning November 1, 2007 through October 31, 2008; the resulting estimates by accident year are weighted to arrive at a projected average loss per car; the projected average loss per car is adjusted to reflect investment income expected to be earned on insurance company operations; an average expense provision (as a percent of premium and fixed dollar amount) is selected; an average health services levy provision (as a percent of the TPL premium) is selected; an average profit provision (as a percent of premium) is selected; and the projected average loss per vehicle (adjusted to reflect investment income on cash flow), the selected average expense provision, the selected average health services levy provision, and the selected average profit provision are combined 3 to determine the estimated required average premium per vehicle. The exhibits we have attached reflect the assumptions we have made and the factors and provisions we have selected. This methodology can be used by the Board to estimate the required average premium (and hence the Industry-wide rate level adjustment). Should the Board select different assumptions, factors, or provisions, it can apply the same methodology. 3 The method for combining the selected provisions is to calculate the product of: the projected average loss cost, the present value factor, and the premium delay factor. This product is then divided by 100% less the sum of: the variable expense provision, the health levy provision, and the profit provision; and then the adjusted fixed expense is added.

32 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the Average Street Premium To calculate the Industry-wide rate adjustment, the required average premium that is determined for the policy year effective November 1, 2007, must be compared to the estimate of the street premium. We estimate the street premium based on information we obtained from IBC and from the Board staff. IBC provided monthly written premiums and cars insured for Third Party Liability and Benefits during 2006 and first three months of 2007, ending March This is referred to as fast-track data, as it is preliminary and does not include all insurers. The average written premium for basic coverages during January to March 2007 was $609. We assume this is a reasonable estimate of the average street premium as of March We test this $609 estimate for reasonableness by using the average street premium based on the reported average written premium for the second half of 2006 ($613.96), as presented in the AU70A exhibit, prepared as of December 31, We adjust this average ($613.96) based on approved rate change information between July 1, 2006 until May 1, 2007 provided to us by the Board staff, the Board mandated November 1, 2006 Industry-wide adjustment of -3% and -1.2% for Grid rates. Based on these calculations, we estimate the average written premium as of March 1, 2007 to be within one percent of the IBC fast-track data estimate of $609. We therefore assume that the $609 estimate based on the IBC fast-track data is a reasonable estimate. We adjust this estimated average street premium as of March 2007 of $609 for anticipated premium trend that results from insureds increasing their Third Party Liability limit of coverage. Based on a review of changes in the distribution of insureds by the limit of coverage they purchase, we assume a Third Party Liability premium trend of 0.16% per year. Our estimated average street premium during the middle of the policy year effective November 1, 2007 is, therefore, $ Oliver Wyman 30

33 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the While we acknowledge there may be changes made by individual insurers to either increase or decrease their rate levels (in addition to the Industry-wide adjustment to become effective November 1, 2007), we make no adjustment to our estimate of the average street premium for such possible future actions. Indicated Industry-wide Rate Level Adjustment The indicated Industry-wide rate level adjustment is the percentage difference between the estimate of the required average premium and the estimate of the average street premium.

Insurance Coverages We begin with a general description of the insurance coverages. We note that throughout this discussion of the insurance coverages, the term insured is generally used to mean the family of the owner of the policy, as well as any passengers or other drivers using the car with the owner s permission. Third Party Liability (TPL) There are two parts to this mandatory coverage: Bodily Injury (BI) coverage protects the insured against liability arising from an accident that causes bodily injury to another person. Coverage amounts available in Alberta range from the legal minimum of $200,000 per claim to well over $2,000,000 per claim. Property Damage (PD) coverage protects the insured against liability arising from an accident that causes damage to the property of another person. Oliver Wyman 32

35 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the All drivers must purchase at least the legally required minimum amount of TPL coverage available in Alberta. Benefits (AB) This coverage provides for such items as reimbursement of lost income, medical care costs, and funeral costs; it also provides benefits to the dependants of a deceased insured. Underinsured Motorist (UIM) This optional coverage protects the insured if he or she is caused bodily injury by an atfault driver who is insured, but who does not have sufficient insurance to cover the liability; in this case the insured collects, from his or her own insurer, the amount of the damage that is in excess of the at-fault driver s liability coverage and up to the limit of UIM coverage purchased. Collision This optional coverage generally provides coverage (subject to a deductible) for damage to the insured s vehicle arising out of a collision. Comprehensive This optional coverage generally provides coverage (subject to a deductible) for damage to the insured s vehicle arising out of a peril other than collision (e.g., theft, vandalism, flood, hail, fire, etc.). All Perils This optional coverage combines the coverages for both collision and comprehensive into one coverage, subject to a common deductible level. Specified Perils This optional coverage, like collision and comprehensive, provides coverage (subject to a deductible) for specific perils to the insured s vehicle. Oliver Wyman 33

36 Actuarial Analysis for Industry-wide Rate Level Adjustment Effective November 1, 2007 Private Passenger Automobile Prepared for the Other Terms Year The year in which an incident that gives rise to a claim occurred, regardless of when the claim is actually reported to an insurance company. For example, a claim reported on January 15, 2003 for injuries suffered in an automobile accident that occurred on December 15, 2002, is considered to be an accident year 2002 claim. Allocated Loss Adjustment Expense (ALAE) ALAE is the claim and settlement expense that can be associated directly with individual claims (e.g., legal expenses). (See ULAE) Base Rate and Rate Differentials Insurers generally determine the premium for a particular insured by multiplying a base rate by a series of rate differentials (or rate factors, or rate relativities) that reflect the particular characteristics of the insured. The terms rate differentials, rate factors and rate relativities are used interchangeably. Typically, there is one base rate for each combination of coverage and rating territory. For example, assume a base rate for the TPL coverage of $200 in Territory #1 and a base rate for the TPL coverage of $300 in Territory #2. Also assume the rate differential for a married male driver, age 40, is The TPL premium for this driver would be $250 in Territory #1 ($200 times 1.25) and $375 in Territory #2 ($300 times 1.25). Case Reserve The Case Reserve is the provision established by insurance companies for the payment of future losses and claim related expenses associated with a particular claim. Claim Frequency Claim Frequency is the average number of claims that occur in a year, per insured vehicle. Claim frequency is a measure of the incidence of automobile claims. For example, if an insurance company provided insurance on 100 vehicles in year 2002 and 5 TPL claims occurred during 2002, the company s TPL claim frequency for 2002 would be 5 percent.
