Franchise Value and Firm Profitability: The Case of the Property-Liability Insurance Industry Abstract Word-of-mouth reputation or franchise value (FV) is critical to the profitability of a financial firm. We accommodate two channels of FV effects on the profitability of property liability insurers. One is a reputation effect where high FV insurers charge more to policyholders and operate with lower expenses. The other is a solvency effect where firms with greater FV may be more prudent in risk taking, with lower insolvency risk and greater profitability. We show that through both channels insurer profitability increases in franchise value ceteris paribus. A more interesting prediction is that in the absence of a major capital shock to the insurance industry the FV effect on firm profitability is greater in more competitive soft insurance markets than in hard markets. We empirically examine the FV effect on insurer profitability and measure FV using financial strength ratings after controlling for tangible firm characteristics. The results are consistent with these predictions. The study should be of interest to financial intermediaries, analysts, investors, and regulators given recent turmoil in the financial services sector. 1 Franchise Value and Firm Profitability: The Case of the Property-Liability Insurance Industry “We can afford to lose money–even a lot of money. We cannot afford to lose reputation– even a shred of reputation. … Berkshire is ranked by Fortune as the second-most admired company in the world. It took us 43 years to get there, but we could lose it in 43 minutes.” -- Warren Buffet, 2006 1. Introduction Financial firms provide contract or service agreements where contingent payoffs occur at a future point in time. Product quality is largely derived from customer trust in the firm, word-of-mouth reputation, and brand loyalty. Insurers are no exception. Product quality rests not only on an insurer’s financial strength to pay claims but on reputation-based assets known as franchise value (or intangible assets or charter value). Insurer franchise value includes firm name recognition, brand loyalty, renewable business, and expertise in claim service and underwriting. While franchise value is difficult to quantify using standard accounting measures, it is critical to insurer profitability.1 The effects of similar intangible assets on firm performance have been examined in studies on industrial firms (see, for example, Aaker 2001; Chan, Lakonishok, and Sougiannis 2001; Barth, Clement, Foster, and Kasznik 1998; Lehmann 2004) but have not been modeled or empirically tested for the financial services sector, specifically the insurance industry. This study attempts to fill this void. We develop a model on the effects of franchise value on insurer profitability, construct an innovative measure for intangible assets, and provide empirical evidence on the effect of franchise value on insurer profitability. Given the contingent nature of insurance where claims payment occurs long after insurance is purchased, the perceived quality of an insurer, such as having a good rating, plays a strong role in determining insurer profitability. In a simple model we consider 1 The recent experience with the American International Group (AIG) Inc after being bailed out in 2008 clearly exemplifies the franchise value effect on insurer profitability. Echoing Warren Buffet’s comments on firm reputation, Bloomberg reports that in the third quarter of 2009 “AIG suffered an 87% quarterly sales decline at its European life business as U.K. clients abandoned the firm due to its ‘tainted brand’”. See http://www.bloomberg.com/apps/news?pid=email_en&sid=amabV1Im9w84 for details. 2 two channels of franchise value effects on firm profitability. In the first channel, insurers with higher franchise value have greater name recognition and brand loyalty, enabling them to charge a higher premium (i.e., a greater loading) and benefit from a policy distributional cost advantage (e.g., reduced expense). While franchise value provides insurer advantage there is also a downside to firm investment in these intangible assets: when an insurer becomes insolvent intangible assets are not readily recovered. The negative effect of possible insolvency however is bounded by the benefits. The difference is referred to as the reputation effect. 2 Moreover, a second franchise value effect on profitability comes from the reduced insolvency risk. The literature, e.g., Babbel and Merrill (2005) and Yu et al. (2008), suggest that high franchise value firms typically are more prudent in risk taking. The lower insolvency risk results in higher premiums (thus greater profitability) for high franchise value firms. This is a potential additional benefit of insurer investment in intangible assets: an improved solvency effect for the firm. Overall we expect that insurer profitability increases with franchise value given these two effects, reputation effects and solvency effects. The property liability market is known to be cyclical with lower realized (than expected) claim costs, increased insurance supply and lower prices in soft markets and constrained supply and higher prices in hard markets (e.g., Venezian, 1985; Cummins and Outreville, 1987; Winter, 1994). The variations in supply and shifts in prices drive differing levels of competitions in the insurance market, which presents a natural setting to observe a dynamic version of the franchise value effect under heterogeneous market conditions. Specifically, in the more competitive soft markets, insurers with stronger name recognition and underwriting and claims service expertise are able to charge a price differential for the expense load and maintain the benefits of efficient distribution relative to lower franchise value insurers. Thus we expect a stronger FV effect in soft markets than in hard markets.3 2 With the reputation effect, the insurance market may not be perfectly competitive. Rather, insurers with more franchise value have greater market power. Commonly considered in the banking literature, such market power would be justifiable under economic models of monopolistic competition with product differentiation (Keeley, 1990; Gan, 2004). The insurance market is known to be opaque (Ross, 1989; Polonchek and Miller, 1999; Zhang, Cox, and Van Ness, 2009), potentially resulting in greater switching costs and making it easier for high FV firms to retain clients. 3 An exception would be when the insurance industry is hit by a major shock leading to widespread insolvency and clients then fly to quality. In these cases the FV effect would be stronger in hard markets 3 Testing these predictions is not an easy task since there is not a ready measure for franchise value for insurers. Franchise value is intangible and rarely recognized in financial statements. Lev and Zarowin (1999) and others argue that quantifying intangibles is where the current accounting system fails most seriously in reflecting enterprise value and performance. Other studies use various proxies to evaluate franchise value (intangible assets): Tobin’s q (e.g., Keeley 1990; Staking and Babbel 1995; Gan 2004) or accounting entries such as research and development expenses or advertising expenses (e.g., Chan, Lakonishok and Sougiannis 2001). For our study use of these proxies is not appropriate for evaluating insurance franchise value since the majority of insurance firms are privately held and firm market value and other accounting variables are not publicly available information.4 Instead we rely on the assessment by insurance experts of an insurer’s strength and market standing, using the A. M. Best’s Financial Strength Rating.5 Insurer ratings have been widely used as measures of insolvency risk and an insurer’s overall financial quality (see, for example, Best, A. M., 2008; and Adiel, 1996; Anthony and Petroni, 1997; Cummins and Danzon, 1997; Pottier, 1998; Pottier and Sommer, 2002). 6 As an insurer’s rating would be simultaneously influenced by both tangible and intangible values, we construct a rating-based franchise value measure that separates franchise value from tangible assets. It is the financial strength rating of an insurer adjusted for the average rating of firms with comparable tangible characteristics. We measure insurer profitability using returns on assets (ROAs), return on equity (ROEs), the insurers’ combined loss and expense ratios (abbreviated as combined ratios, or CRs), and the economic loss ratios (the total discounted value of claims as a fraction of when insolvency risk becomes a major consideration (as was the case in the recent financial crisis). We nevertheless consider this type of crisis as an abnormal case. 4 The nature of the insurance business is substantially different from that of industrial firms. Even if these accounting variables were available using them requires particular caution. 5 For robustness, we consider alternative proxies for insurer franchise value and test their effects on firm profitability. We apply insurer regression-based residual ratings as an alternative measure, use a “young firm” indicator variable as a proxy, and sort by insurance groups. Results are robust across measurement conventions. 6 A Best’s Financial Rating is “an independent opinion of an insurer’s financial strength and ability to meet its ongoing insurance policy and contract obligations” (Best A. M. (2008)). Ratings are typically considered as a comprehensive measure of insolvency risks (e.g., Pottier and Sommer, 1999; 2002; Doherty and Phillips, 2002). In our analysis, we use ratings as an all-inclusive measure for an insurer’s market standing. This is reasonable given that i) high ratings are assigned to firms of greater financial strength and ii) various attributes related to firm financial strength are included as rating determinants, including profitability, quality of management team, firm size, and capital adequacy (e.g., Best A. M. (2008) and Pottier and Sommer, 1999; 2002). 4 premiums net of expenses, abbreviated as ELRs). To test the predictions of the model, we use a sample of property and liability insurers over the period 1985 to 2008. We first perform portfolio analysis to examine the average relationship between franchise value and insurer profitability. Insurers are sorted into deciles based on their franchise value and operating performance in the subsequent year for each decile is estimated. As expected we see that firm profitability increases with franchise value. These results are consistent with our expectation and the findings in Chan, Lakonishok, and Sougiannis (2001) where industrial firms with high franchise value outperform those with low franchise value in terms of future stock performance. Next we use regression analysis to allow controls for a range of firm characteristics (other than franchise value) that may affect operating performance. The set of control variables includes firm size, ownership structure, group affiliation, product concentration (by line of coverage), use of reinsurance, a measure for the competitiveness of the insurer, the investment percentage in common stocks, and lagged operating performance. The result shows that the coefficient on franchise value is positive and statistically significant, indicating that the link between operating performance and franchise value is robust. Next, we test the differential franchise value effects in soft and hard markets. We measure market condition using the industry-wide average loss ratios where high industry loss ratio indicates a hard market. Consistent with our expectations, we find that across all profitability measures, the average spreads in firm profitability between the top and bottom franchise value firms are positive in both hard and soft insurance markets. Further, the average spread is greater in soft markets. Our study is distinct from other research in that we focus on the franchise value effect on profitability of financial service firms, where the word-of-mouth effect is critical. The paper perhaps most closely related to our paper is Epermanis and Harrington (2006) where they find insurer premiums decline in the year and the year after insurers experience rating downgrades. Our paper however differs from Epermanis and Harrington (2006) in that we specifically analyze the effect of franchise value on profitability, rather than looking at the overall rating effects. Our work also follows Babbel and Merrill (2005), who suggest that franchise value is inversely related to firm insolvency risk and that increases in franchise value decrease the insurance contract put 5 option value. Our analysis on the role of franchise value in different market conditions extends the theoretical framework discussed in Babbel and Merrill (2005) and provides empirical evidence. Other franchise value literature focuses largely on firm risk taking (e.g., Keeley 1990; Gan 2004; Yu, Lin, Oppenheimer, and Chen 2008). Although there are studies on the impact on profitability of franchise value, these studies are exclusively on industrial firms. The remainder of the article is organized as follows. Section 2 presents a model on the effect of franchise value to firm profitability and discusses testable hypotheses. Section 3 describes the data and empirical methodology. Section 4 presents our empirical findings regarding hypothesized franchise value effects. Section 5 concludes the paper. 2. Franchise Value and Firm Profitability We first derive the relation between franchise value and cross sectional firm profitability in a simple model. Based on the model’s predictions, we then develop testable hypotheses to guide our subsequent empirical analysis. 2.1 The Baseline Model We consider a simple one-period model (t=0, 1) to demonstrate the effect of franchise value on firm profitability in the insurance industry. In the same spirit as Keeley (1990), we model franchise value in a non-perfect competitive market setting. The interest rate is set to be zero for simplicity. In the model an insurer writes policies and receives premiums at t=0. The nonstochastic claim liabilities, L, are incurred during time 0 and 1 and are fully paid at t=1. The insurer evaluates its profitability at t=1. At t=0, the firm’s assets (A) include both tangible assets (t) and franchise value (f). The firm’s franchise value is F as long as the firm is solvent and drops to 0 when the firm is insolvent. (1) A=τ+f The value of tangible assets, τ, follows a geometric Brownian motion. observe that 6 We (2) d dt dW where is the expected rate of return on tangible assets and is the standard deviation of tangible assets; W represents a Wiener process. At t = 1, the aggregate profit made by the insurer is denoted as (3) PC E, where P is the premium collected by an insurer; C is the claim payment made by an insurer and E is the insurer’s expense. There is insolvency risk and insolvency is costly due to the loss of franchise value. As the insurer holds a limited liability to policyholders its claim costs would equal the value of tangible assets when the insurer is insolvent; the claim costs equal the full amount of liabilities when the insurer is solvent. That is, (4) C= τ if L ≥ τ (insolvent) C=L if L < τ (solvent) We have the following expression for the expected value of claim cost at t=0: (5) L 0 L EXP(C ) tg ( )dt Lg ( )d L L ( L ) g (t )d 0 = L – PUT (6) L PUT ( L ) g ( )d 0 Note that in Equations (5) and (6) claim liabilities, L, are fixed while the amount of firm tangible assets, τ, is stochastic. In (6), the expected claim cost is identical to the expected payoff of a risky bond (see Cummins, 1991). That is, the expected claim cost of an insurer equates the payoff of a risk free bond with a face value of L minus the value of a put option on firm tangible assets with L as the exercise price. In our setting, insurers take a long position in the put option, entitling the firm in the event of insolvency to receive a minimum payment of L upon liquidation at t=1. This gives rise to a loss to policyholders, who take a short position in the put option. PUT here is the amount that the insurer fails to deliver when it defaults. Following (5), as long as insurers have a positive value in their claim costs (i.e., EXP(C)>0), we have L > PUT. That is, the upper bound for the value of PUT is L. 7 With PUT clearly defined, we express premiums collected by an insurer at time 0 as below: (7) P (1 )( L PUT ) where λ (≥0) represents the percentage loading (of expected claims) that the insurer charges policyholders. In practice, franchise value empowers insurers to charge a relatively greater loading, thus, (8) 0 F Insurer expense, E, is proportional to the insurer’s expected claim costs, EXP(C): (9) E e( L PUT) where e (≥0) is the expense ratio of the insurer. An insurer’s expenses cover the insurer’s acquisition and underwriting expenses. Greater franchise value may help firms reduce both costs. Thus, we expect: (10) e 0 F Now, we can express the insurer’s expected profit in t=0 as below: (11) E ( ) P Exp (C ) E ( e)( L PUT ) ( L PUT ) where β (=λ-e) represents the net loading (i.e., the insurer’s proportional loading in excess of its expense ratio). Equation (11) states that the insurer’s aggregate profit is proportional to its claim liabilities in excess of the value of the firm’s insolvency put option. We are interested in knowing how FV affects insurers’ unit profitability. Thus, we divide both sides of (11) by L and denote E ( ) and put=PUT/L (the value of the L insolvency put option per unit of the insurer’s liability, ranging between 0 and 1). This gives us the following expression: (12) (1 put ) Taking the derivative of π with respect to F, we have, (13) put (1 put ) * F F F (1) ( 2) 8 The first term of the above expression, (1 put ) , may be considered as the FV F effect on reputation (or simply the reputation effect). It is non-negative given that 0 and 0 ≤ put ≤ 1. F The sign for the second term, * Appendix A, we show that put put , depends on the sign of . In F F put 0 under the condition that tangible assets of high-FV F firms exhibit first-order stochastic dominance (FSD) over tangible assets of low-FV FSD firms (denoted as h l .where h and l refer to high- and low-FV firms). Intuitively, FSD of high-FV firms over low-FV firms suggests that high-FV firms have a greater cumulative density in the solvency region (t>L) than do low FV firms. As a result, highFV firms are lower in their put option value. We consider this as the FV effect on insolvency risk (or simply the solvency effect). This is consistent with empirical evidence that high franchise value firms are more prudent in risk taking (see, e.g., Babbel and Merrill, 2005 and Yu et al., 2008). There is another perspective to consider. The first term in expression (13) represents the premium component of a high FV firm that is due to its market power. The second term represents the reduction in insurers’ risk premium to investors for high FV firms. Since both terms are positive for high FV firms, we have the following proposition: Proposition 1: A sufficient condition for 0 is that tangible assets of high-FV firms F exhibit first-order stochastic dominance over tangible assets of low-FV firms. 2.2 Effect of Underwriting Cycles The property liability insurance industry is characterized by underwriting cycles where the supply of insurance is adequate in soft markets but the supply falls in hard markets (Venezian, 1985; Cummins and Outreville, 1987). Soft markets are generally viewed as a buyer’s market while hard markets are viewed as a seller’s market. The variation in supply and shifts in prices drive changing levels of competition in the 9 insurance market -- soft markets are more competitive than hard markets. This would result in heterogeneous FV effects on profitability across insurance underwriting cycles and present a natural setting to further look into the franchise value effects. Corresponding to the two components of the FV effects expressed in (13), we have the following conditions. First, FV potentially plays a greater role in soft markets since the reputation effect is stronger in soft markets as insurers drop price and competition for customers increases; any competitive advantage, including insurer reputation and name recognition, are relatively more valuable to the insurer in a soft market relative to a hard market environment. That is, (14) h F s F h where the subscript s represents soft markets and h represents hard markets. Second, the value of the put option is lower in soft markets than in hard markets since insurers’ insolvency risk is lower in soft markets. (15) put s put h Jointly, (1 put s ) (1 put h ) . F s F h Third, the solvency effect may be stronger in hard markets (since high franchise value firms typically are more prudent in risk taking, thus lowering insolvency risk and enhancing profitability). That is, put put . Further, s h since more F s F h intensive competition in soft markets erodes loading. Taken together, (16) s * put put h * F F s h With (16) however the FV effect is stronger in hard markets. Without the disruption of major catastrophes, insurers’ default probability is typically low and one would expect that s put put is bounded by a low number.7 Then the FV effect h F s F h 7 Insurance companies typically are well capitalized. As reported in Cummins, Harrington, and Klein (1995), the average number of insolvent insurers over the period 1979 to 1992 is 23, fewer than 1% of all property casualty insurers. In addition, as reported in the Best’s Aggregates and Averages, the annual loss 10 would be stronger in soft markets. A strong franchise value effect on the option put ( put 0) would topple this condition however and one would expect a stronger F s franchise value effects in hard markets. Proposition 2: When s put put is bounded by a relatively low number, the h F h F s effect of franchise value on firm profitability would be stronger in soft markets, i.e., put put . Otherwise, when s is unbounded. h F s F h F s F h F h F s Note that the alternative case ( ) is more likely to hold in the aftermath F s F h of a major catastrophe resulting in wide spread insolvencies and severe disruptions in business; in that case we expect that policyholders fly to quality (as stated in footnote 3 above), thus a lower FV leads to a substantially higher put value. 2.3 Testable Hypotheses Hypothesis 1 strictly follows from the first proposition on the relationship between firm profitability and franchise value: H1: Insurer profitability is positively related to franchise value. Aligned with the first hypothesis, we have the following prediction regarding the franchise value effects in soft and hard insurance market conditions: H2: Insurer profitability is positively related to franchise value in both soft and hard insurance markets. Further, hypothesis 3 addresses the differential franchise value effects on insurer profitability across insurance underwriting cycles. As the market is more competitive in soft markets than in hard markets, in soft markets insurers with stronger name recognition and underwriting and claims service expertise are able to charge a price differential for the expense load while maintaining the benefits of efficient distribution relative to lower franchise value insurers. As noted earlier insolvency is not widespread in the insurance industry, following Proposition 2 we expect a greater FV effect in soft markets than in ratios (incurred losses/earned premiums) for all property and liability insurers are not wildly fluctuating, ranging between 70% and 100%. 11 hard markets (given that there are no major business shocks, i.e., normal business conditions exist). H3: In the absence of major disruption in the insurance market, the effect of franchise value on profitability is stronger in soft markets than in hard markets. 3. Data and Methodologies 3.1 Data We obtain rating data from the A.M. Best Key Rating Guide Database for property-casualty insurers (hereafter, the Best database). Financial statement data are obtained from the National Association of Insurance Commissioners’ database for property-casualty insurers (hereafter, the NAIC database). The firm identifier in the Best data is the “BEST Number”, while the firm identifier in the NAIC data is the NAIC Code. We use the link provided in the Best data to combine these two databases. Our data spans the period of 1985 through 2008. Following prior studies (e.g., Cummins, Dionne, Gagne, and Nouira 2009), we set the following criteria to ensure a clean sample: (1) insurers have non-missing rating information in the Best database, (2) if an insurer has less than $1 million total assets any year, it is removed from our sample, (3) insurers are covered by the NAIC database with non-negative surplus, assets, losses or expenses, (4) we remove the top and bottom 1% of insurers based on the four performance measures, (5) insurers with non-missing profitability measures (described in section 3.3), and (6) group level insurers are removed from the sample. Our analysis primarily focuses on the individual firms since this includes a much larger industry cross section.8 From 1985 to 2008, there are 74,617 firm-year observations and 5,704 unique insurers in the NAIC data. After adhering to restrictions (2) through (6), there are 37,294 firm-year observations and 3,231 unique insurers. After matching the NAIC data with the Best data, we obtain a sample with 23,047 firm-year observations from 2,145 unique insurers. 8 The Best and NAIC databases both cover insurance groups and individual insurers. NAIC assign NAIC Code no greater than 10000 for insurance groups and NAIC code exceeding 10000 for individual insurers. We only include firms with their NAIC codes exceeding 10000. 12 3.2 Measuring Franchise Value Measuring franchise value is challenging given that standard accounting conventions are not adequate.9 The basis of our franchise value measure is the Best’s rating of an insurer. According to the Best Guide, “a Best’s rating is an independent opinion, on a comprehensive quantitative and qualitative evaluation, of a company’s balance sheet strength, operating performance, and business profile”. In other words, the Best’s rating of an insurer captures its financial standing in a comprehensive way. It jointly reflects an insurer’s tangible and intangible assets (i.e., franchise value). Our approach is to extract franchise value by removing the tangible assets component from the Best rating. We consider three firm characteristics for tangible assets: book value of firm assets, leverage, and an insurer’s prior year’s operating performance. In each year, we sequentially sort insurers into 27 (3 x 3 x 3) groups based on firm total assets, then on leverage, and finally on return on assets, all evaluated in the prior year. For each of the 27 portfolios, we calculate the equal-weighted average rating in each year and use it as the benchmark. Note that Best Company assigns insurers letter ratings from S (Suspension) to A++ (superior). Consistent with prior studies (see, for example, Colquitt, Sommer, and Godwin (1999)) we assign a numerical number to each letter rating, ranging from RATING = 0 for the Best’s Rating of S (suspended), F (liquidation), or E (under regulatory supervision) to RATING = 13 for the Best’s Rating of A++.10 When multiple ratings are reported for an insurer in a year, we use the last reported rating in that year. The difference between the rating of an individual insurer and the average rating of its benchmark group is the benchmark-adjusted franchise value. It is possible that an insurer may have a high raw FV measure (FVR) simply by chance rather than because of relatively greater intangible assets. An insurer indeed with high franchise value is expected to persistently have high franchise value over multiple periods. We therefore compute the rolling average of FVR over three years (from year t-2 to t) to increase the likelihood that our measures capture true franchise value: 9 As noted above Lev and Zarowin (1999) and others argue that quantifying intangibles is where the current accounting system fails most seriously in reflecting enterprise value and performance. 10 More specifically, the numerical number for each of the A.M. Best ratings is as below: 0(E, F and S), 1 (D), 2(C-), 3(C), 4(C+), 5(C++), 6(B-), 7(B), 8(B+), 9(B++), 10(A-), 11(A), 12(A+), and 13(A++). 13 (17) 3.3 FVi ,t 1 0 FVi ,Rt 3 2 Profitability and Firm Characteristics Measures Four traditional profitability measures are used in our analysis. The first is return on assets (ROA), calculated as net income scaled by beginning period total assets. The second is return on equity (ROE), calculated as net income scaled by beginning period total equity. The third is the combined ratio (CR), calculated as the ratio of losses (claims paid) and expenses to the premium earned. The last profitability measure is the economic loss ratio (ELR). The calculation of ROA, ROE, and CR is straightforward based on balance sheet and income statement information of insurers covered by the NAIC database. The estimation of ELR follows the spirit of Winter (1994) with estimation details provided in Appendix B. For all profitability measures, we remove the top 1% and bottom 1% observations in each year to control for the impact of outliers. It should be noted that we look at how insurer profitability responds to franchise value in the prior year. Also note that insurer franchise value is the three-year rolling average of an insurance financial strength rating adjusted for the average rating of firms with comparable tangible characteristics in the preceding year. As a result, our data (with insurer characteristics information starting from 1985) facilitates an analysis of insurer profitability starting from 1989. Various firm characteristics, other than franchise value, potentially play a role in determining operating performance. We construct the following control variables: total assets (SIZE), the ratio of total liabilities to total assets (LEV), the Herfindahl index by business line (HERFL), the Herfindahl index across different states (HERFS), the degree of competition faced by each insurer (COMPETE), the percentage of reinsurance in direct insurance business (REINS), an indicator for group affiliation (GROUP), an indicator for stock ownership (STOCK). Appendix C provides definitions for these variables. Panel A of Table 1 reports summary statistics for insurer franchise value, operating performance measures and various firm characteristics used in the analysis. For each variable, we include the time-series averaged number of observations, mean and median, standard deviation, minimum and maximum. The average number of firms is 14 1034. The mean of franchise value is 0.03 with minimal of -7.48 and maximum of 4.00. The mean return on assets is 2.81% per annual while the mean return on equity is 6.92% per annual. While the average combined ratio is 106.65%, the average economic loss ratio is 95%, suggesting that with consideration of the time value of money, on average insurers make a profit from their underwriting business. Most insurers are affiliated with groups (70%) and have stock ownership (70%). In Panel B, we show the correlations among variables. Franchise value is positively correlated with ROA (0.09) and ROE (0.11) but negatively correlated with combined ratios (-0.08) and economic loss ratio (-0.07), which is consistent with positive expectations about FV on profitability. The four measures of insurers’ profitability are highly correlated with each other. The correlation between ROA and combined ratio is 0.55 and the correlation between ROE and ROA is 0.89. GROUP is highly correlated with REINS (0.28) indicating that firms affiliated with a parent tend to purchase more reinsurance. In addition, GROUP is positively correlated with STOCK (0.34) (i.e., affiliated firms are more likely to be stock companies). In Panel C, we take a snapshot of insurer characteristics across franchise value deciles. In each year, insurers are classified into deciles based on their franchise value: D1 insurers have the lowest franchise value, while D10 insurers have the highest. Firm characteristics in the same year are evaluated and presented. Relative to D1 firms, firms in the D10 group are larger in firm size and have a longer history of operation. Also, D10 firms are relatively more diversified, buy more reinsurance, and engage in more diversified business lines. Lastly, high franchise value firms are more likely to be affiliated with a group and they are more likely to have stock ownership. 4. Main Empirical Results 4.1 Franchise Value and Firm Profitability Our first hypothesis posits a positive relationship between franchise value and insurer profitability. We explore the relationship using portfolio analysis. We sort insurers into deciles based on franchise value in each year and estimate insurer combined ratio, return on assets, and return on equity in the subsequent year. D1 insurers have the lowest franchise value, while D10 insurers have the highest. Panel A of Table 2 reports 15 the results, where the reported portfolio performance is the time-series average of crosssectional means of the profitability measures. The cross-sectional means are calculated using equal-weights. The first column reports insurer return on assets on FV-sorted deciles. Return on assets increases when franchise value increases. Return on assets is 2.03% for D1 insurers and it is 3.04% for D10 insurers. Their difference of 1.01% is significant at the 1% level (t=5.77). The second column reports return on equity on FV-based deciles. There is still a pattern of increasing return on equity when franchise value increases. The third column shows the combined ratio across franchise value deciles. For property and liability insurers, the combined ratio is a typical measure of operating performance. The evidence suggests that the combined ratio decreases as franchise value increases. The combined ratio for D1 insurers is 111.55%, while that of the D10 insurers is 105.05%. The difference of 6.50% is significant at the 1% level (t=-4.49). Another interesting pattern we can observe from column one is that for all insurer deciles, the combined ratios are greater than 1. That is, during our sample period from 1985 to 2008, on average, premium earned is smaller than associated claims without considering the time value of money. When looking at the economic loss ratio, we find ELR for D1 insurers is 99.59% and it is 93.60% for D10 insurers. Their difference of 5.99% (t=-5.25) is significant, both statistically and economically. In Figures 1 and 2, we look at the difference in the alternative profitability measures between D10 and D1 portfolios sorted by insurer franchise values over time. In Figure 1, we show the return spread in each of our sample years. The plots show that D10 portfolios stably beat D1 portfolios in almost every year over our sample period. In Figure 2, we look at the D10-D1 spread in each of the five years subsequent to the franchise value measurement year. We find that that D10 firms are remarkably more profitable in every year of the subsequent five years since the franchise value evaluation year. Next, we use regression analysis to examine whether high franchise value firms tend to have better operating performance. The advantage of regression relative to portfolio analysis is that it allows us to control for other factors that may also affect insurer profitability. Franchise value is not the only factor that affects insurer 16 profitability. According to prior studies, we consider eight insurer characteristics that have been shown to be associated with firm profitability: SIZE, LEV, HERFL, HERFS, COMPETE, REINS, GROUP, and STOCK. The definitions of these variables are provided in Appendix C. We include fixed firm and time effects in the regression by including both firm and year indicator variables in the regressions. Moreover, as our sample firms come from the same industry for multiple years, the residuals may be correlated across firms and/or across time. We follow Petersen (2009) to allow for correlation of residuals using the two-way clustering method. The model is specified as follows: (18) PROFITi,t 1 X ' i,t 1 i1 vt1 i1,t where PROFIT i ,t is insurers’ profitability (ROA, ROE, CR, or ELR) of insurer i at the end of year t; X i',t 1 is a vector of insurer i’s franchise value and other firm characteristics in year t-1; ik (k=1,2) is a firm-specific intercept; v ik (k=1,2) represents the timespecific dummy, and vi , j ~ IID (0, v2 ) . ε is a random error term assumed to be heteroskedastic and correlated within firms and years. We present the results in Panel B of Table 2. The franchise value coefficient in the ROA regression is 0.18 (t=7.24), and it is 0.55 (t=7.90) in the ROE regression. In the CR regression, the FV coefficient is -0.92 (t=-5.30), and it is -0.99 (t=-5.88) in the ELR regression. The impact of franchise value seems to be substantial. For instance, when franchise value increases by 1 unit, the average decrease in ELR is nearly 1%. The evidence suggests that, after controlling for the impacts of other insurer characteristics, franchise value still has significant impact on insurer underwriting profitability and comprehensive profitability. We also find that lagged-year firm profit, firm size, leverage, Herfindahl index by insurance line, competition, reinsurance, and ownership structure, all have impact on at least one of the performance measures. The coefficient of SIZE in the ROA regression is 0.10 (t=2.22), suggesting that larger insurers are more profitable. Moreover, the use of reinsurance is negatively related to future performance. This result is consistent with the finding in Cole and McCullough (2006) that firm reinsurance use is negatively associated with firm profitability. It is either due to the fact that reinsurance is a costly risk transfer 17 mechanism (thus lowering insurers’ profitability) or less financially strong insurers buy relatively more reinsurance. 4.2 Do Underwriting Cycles Affect Franchise Value Effects? In this section, we examine the differential franchise value effects in soft and hard markets. We classify our sample into soft and hard market years based on the industry average loss ratio. Soft market years refer to those years when the industry average loss ratios are no greater than the median during our sample period; hard market years refer to periods when the industry average loss ratios are greater than the median during our sample period.11 We calculate the time-series averages of cross-sectional means of insurer performance across franchise value deciles in soft and hard markets and report the results in the Panel A of Table 3. In both markets, we find D10 insurers significantly outperform D1 insurers in both soft and hard markets. This finding supports the second hypotheses, indicating that the positive franchise value effect on firm profitability is neutral of market conditions. More interestingly, the performance differential in soft markets is significantly greater than that in hard markets. For instance, D10 insurers outperform D1 insurers by 1.04% per year in soft markets, while they outperform D1 insurers by 0.49% in hard markets. Their difference of 0.55% is statistically significantly different from zero (t=2.09). We reach the same conclusion when measuring firm profitability using ROE, CR and ELR. The pattern of lower profit spreads in hard markets can be visualized in Figure 1 – where the D10-D1 spreads are low in the years conventionally considered to be hard markets, e.g., 1992, 1993, 2000, and 2001. Next, we perform regression analysis to examine the importance of market conditions on the franchise value effect on firm profitability. We use the product term, FV*SOFT, to capture the impact of underwriting cycle on the FV effect. SOFT is defined as (1 – industry average loss ratio for property liability insurers). As reported in Panel B of Table 3, we see that franchise value is positively related to future performance 11 We perform the analyses here and subsequently using combined ratios to quantify different stages during insurance underwriting cycles. The results are similar to what we report here. 18 regardless of the choice of insurer profitability measures. The coefficients on FV*SOFT have the opposite sign to the coefficients on FV. For instance, in the regression of ROA, the coefficient on FV is 0.59 (t=1.83), while the coefficient on FV*SOFT is 0.64 (t=1.98). That is, the franchise value effect will be stronger when the industry loss ratio is lower. We interpret this as evidence confirming the third hypothesis that the role of franchise value on performance is weaker in hard markets. A caveat on our empirical finding is that though we find stronger FV effects in soft markets, this is attributable to the relatively smooth condition in the insurance market. Recall our proposition 2 does not provide a sure prediction regarding the impact on insurance underwriting cycle on FV effects. We might expect a stronger FV effect in hard markets where policyholders may escape from firms with lower franchise value. In Cummins, Doherty, and Lo (2002), they conduct a simulation analysis which shows the U.S. property and liability insurance industry can fund a USD100 billion loss event (with a total equity capital of USD350 billions).12 In case this limit is reached, we may observe the FV effect is otherwise stronger in hard markets. This prediction is echoed by the casual observation that some banking giants, like Goldman Sachs and Bank of America, took large market shares and turned highly profitable shortly after the 2007-2008 financial crises while most financial institutions are still battling with survival and lost clients. 4.3 Robustness Checks 4.3.1 Regression-Based Franchise Value Measures In the above analysis, we use benchmark-adjusted insurer ratings as our franchise value proxy. As a robustness check, we construct regression-based insurer ratings as the franchise value. Specifically, we perform cross-sectional regression each year and use the residual term as the proxy for franchise value, the regression-based franchise value (RFV). We follow Pottier and Sommer (1999) to include a set of firm characteristics that may affect the Best’s rating. RFV is the residual term in the following annual crosssectional regressions: 12 The largest catastrophe in history is Hurrican Katrina, leading to an estimated insured losses of roughly USD45 billion (Kunreuther and Michel-Kerjan, 2007). 19 10 (19) RATINGi,t = α0 + j 1 j X j ,i ,t 1 + i,t where X j ,i ,t 1 (j=1, 2, …, 10) are tangible characteristics potentially affecting the firm rating measured at the end of year t-1. The residual, εi,t, is the regression-based franchise value. Variables used as X j ,i ,t 1 are defined in Appendix D. Relative to the benchmarkadjusted franchise value, an advantage of RFV is that it simultaneously controls for more factors that may affect the Best ratings. However, we are very conservative in estimating franchise value as some factors may have both tangible and intangible components. RFV results are reported in the first two columns of Table 4. For brevity, we only report the results in the regressions using ROA. The results are consistent with what we reported in Tables 2 and 3. The first column shows the effect of franchise value on performance without any interaction term. Franchise value is positive and statistically significant; for example, the coefficient on FV is 0.12 (3.35). The next column examines the impact of the insurance market cycle on the role of franchise value. Here again the evidence suggests that the effect of franchise value is weaker in hard markets. 4.3.2 Profitability of Young Firms It requires time for a firm to develop its franchise value. Firms with relatively short history (young firms) would have little franchise value. If franchise value plays a role in determining insurers’ profitability, we expect young firms to be less profitable than experienced firms. To test this conjecture, we alternatively measure franchise value using an indicator variable, YOUNG, equal to one if the age of an insurer is less than or equal to 10 years, and zero otherwise. With this definition, about one-fourth of our sample firms in each year are young firms and the rest are not. We perform regression analysis to see if YOUNG affects future firm profitability. As reported in the third and fourth columns of Table 4, young firms tend to have worse performance, setting everything else equal. In column four the coefficient on YOUNG is -2.53 (-1.93), which is significant at 10% level. The result shows that on average ROA of young firms is 2.53 percent lower than older firms. It indicates that firms 20 with little or no franchise value are not as profitable as firms with greater franchise value (experienced firms). 4.3.3 Franchise Value Effect at the Group Level Our analysis up to this point focuses on individual firm level analysis, including firms affiliated with each other and stand-alone insurers. One reason for this is that firms in the same insurance group may exhibit different characteristics. For instance, Zanjani (2009) finds that affiliates that are less integrated into the parent organization in terms of risk sharing agreements and ownership relations tend to have lower insolvency probabilities, while flagship companies---large companies at the center of ownership and reinsurance relationships within the group---tend to be at higher risk. Another reason is that information on insurer groups may be incomplete and less accurate. Some parent or holding companies of insurance firms are not insurance companies and thus they do not report their financial statements to NAIC. Moreover, A.M. Best and NAIC may use different criteria for group insurers. Due to these considerations, evaluating franchise value at the individual firm level analyses is more appropriate. For the sake of completeness we provide group level analysis since insurers in the same insurance group may share in franchise value from their parent company and/or investment in franchise value may be decided at the group level. The A.M. Best data only provide the NAIC numbers for individual insurers covered in its database so we must aggregate data in order to do the analysis. We manually match insurance groups in the NAIC database with those in the A.M. Best database. First, we identify all insurance groups in the NAIC database (As mentioned before, insurance groups are assigned an NAIC number of no greater than 10000). Second, we identify all insurance groups in the A.M. Best data using two criteria: there is no NAIC code for an insurer and the aggregate codes indicate that observations are at the group or sub-group level. Finally, we compare company and group names in the two data bases and add the A.M. Best number to the NAIC insurer group if they exactly match. The average number of property and liability insurance groups is 111 and the average group size is $3673 million, much larger than at the individual firm level. 21 Regression results for analysis at the group level are reported in Table 4. The results here are consistent with our prior results: franchise value is positively associated with future firm profitability and the effect of franchise value is stronger in soft market. 5. Conclusions This study examines the franchise value (or intangible asset) effects on firm profitability in the property liability insurance sector. High franchise value (FV) insurers benefit from name recognition and brand loyalty and could charge more to policyholders and operate with lower expenses, thus increasing profitability (a “reputation effect”). Prior research indicates that high franchise value firms typically are more prudent in risk taking, thus lowering insolvency risk and enhancing profitability (a “solvency” effect). FV effects on firm profitability may vary also with market conditions, specifically hard and soft markets which characterize the property-liability insurance industry. Given these varying FV effects the purpose of our paper is to look at the overall role of FV for property liability insurers. We develop a model which predicts that insurer profitability increases in franchise value all else being equal. Both reputation effects and solvency effects are accommodated as are market conditions. We expect that FV effects on profitability are generally stronger in soft insurance markets than in hard markets in the absence of major catastrophes. We construct a new empirical measure of FV and use a large data set from 1985-2008 to test the model. We find evidence consistent with our predictions: firm performance is positively related to franchise value and FV effects differ according to market conditions, with greater franchise value effects in soft markets. Franchise value is an important component contributing to a firm’s sustainable growth and long-term profitability. An interesting aspect of our model is that it shows that, regardless of market conditions (i.e., soft or hard markets), whether normal business conditions exist or it is a crisis period following an exogenous industry shock, franchise value persistently plays a positive role in improving firm profitability. The channel or reason (i.e., the reputation or insolvency effect) by which franchise value positively affects insurer profitability varies, but the positive relationship holds. Given the robustness of the results we expect that our findings are not limited to the property22 liability insurance industry but well may hold for other financial service firms. The study should be of general interest to financial intermediaries, analysts, investors, and regulators given recent turmoil in the financial services sector. 23 PUT 0 F Suppose there are two firms (1 and 2). We assume Firm 2 has higher franchise Appendix A: Condition for value than firm 1 (i.e., F2>F1). We also assume that when firms have higher franchise value, they are more likely to maintain solvency given the same amount to debt. That is, L L 0 g1 ( )d g 2 ( )d for all L, or L L g1 ( )d g 2 ( )d for all L. 0 (A1) The inequality (A1) is equivalent to the condition that, given the differential distribution of tangible assets, firm 2 has first-order stochastic dominance over firm 1. Consequently, L 0 L ( L ) g1 ( )d ( L ) g 2 ( )d for all L. 0 (A2) That is, PUT1 ( ) PUT2 ( ) for all L The inequality (A3) may be rewritten as (A3) PUT 0 . Intuitively we see that high F franchise value firms have more density in the solvency region and thus have lower value in their default options. Taken together, the first-order stochastic dominance of tangible assets of firm 2 to PUT firm 1 leads to 0. F 24 Appendix B: Calculation of Economic Loss Ratios Economic loss ratio (ELR) is an estimate of the aggregate discounted value of claims as a fraction of premiums net of expenses. ELR j ,t LR j ,t 1 ER j ,t 10 ts (1 r s 1 t s )s (B1) where LRj,t represents the loss ratio of insurer j at the end of year t, ERj,t represents the expense ratio of insurer j at the end of year t, rt s is the zero coupon rate for s-year treasury constant maturity rate at the end of year t, ts is the proportion of claims paid in each year since an insurance policy is written in year t, and s is the number of years for the claim payment year since policy year t. It ranges from 1 to 10. ELR is first used in Winter (1994) for industry-wide discounted loss ratios. Different from the Winter (1994) procedure, we estimate ELR for each firm in each year using the Chain Ladder approach (Taylor, 2000). The idea of the Chain Ladder method is to estimate the proportions of claim development pattern using all of the historical claim payment information contained in Schedule P, Part 3 of the National Association of Insurance Commissioners (NAIC) database. The details on the Chain Ladder method are provided in Taylor (2000). We use zero coupon rates corresponding to the gap between the claim payment year and the year when the insurance policy is written. To get zero coupon rates for bonds maturing between years 1 through 10, we collect the yields to maturity of 3-month and 6-month Treasury bills from the St. Louis Federal Reserve Bank's FRED database and the yields to maturity for treasury bonds with maturity closest to 1, 2, 5, 7, and 10 year from the CRSP monthly databases. We apply the extended Neslson-Siegel model (Bliss, 1977) to estimate the term structure of risk-free zero-coupon interest rates. 25 Appendix C: Firm Operating Performance and Franchise Value: Control Variables In the panel regression of operating performance on franchise value, we include control variables in the regression that may affect performance. Lag CR: the combined ratio in the lagged year for each insurer. Lag ROA: the return on assets in the lagged year for each insurer. Lag ROE: the return on equity in the lagged year for each insurer. SIZE: the logarithm of total assets (measured in US$ billions) LEV: the ratio of total liability to total assets HERFL: the Herfindahl index that measures the concentration degree of an insurer. It is the sum of squared ratio of premium earned in a business line of an insurer to the total premium earned by the insurer. That is, HERFL it ( PE ijt / TPE it ) 2 , j 1, 2 ,..., 17 (C1) where PE is the premium earned of insurer I in line j and year t, and TPE is the total premium earned by insurer i in year t. the business line classification j is based on the Best Average & Aggregates. HERFS: ∑(PWi,s /TPWi)2 where PWi,s is premiums written in state s (s=1,2,…,51) of insurer i, and TPWi is total premium written for all sates. HERFS indices evaluate geographical diversifications. The higher the HERFS index measures, the lower diversification is. COMPETE: the degree of competition faced by an insurer. The procedure to estimate this involves three steps: first, compute the Herfindahl index for each of the 17 insurance lines in each year using the top 10 insurers’ premium earned. (C2) HERFL jt ( PE ijt / TPE jt ) 2 , j 1, 2 ,..., 17 Second, find the weights of each of the 17 business lines for an insurer in each year. WGT ijt PE ijt TPE (C3) it Third, calculate the sum of the product of the Herfindahl index for each line in each year and the weights of each line for each insurer: 17 (C4) COMPETE ijt 1 /( 1 HERFL jt * WGT ijt ) REINS: the ratio of reinsurance ceded divided by the sum of direct premiums written and reinsurance assumes for each insurer in each year. GROUP: the dummy variable that equals one if an insurer belongs to an insurance group and equals zero otherwise STOCK: the dummy variable that equals one for stock insurers and zero otherwise. 26 Appendix D: Constructing Regression-based Franchise Value Following Pottier and Sommer (1999), we perform annual cross-sectional regressions of insurer Best’s ratings on tangible firm characteristics. The residuals are the FVCS (i.e., cross sectional regression based FV measure). The regression is specified below: 10 RATINGi,t = α0 + j X j ,i ,t 1 + i,t (D1) j 1 where X includes SIZE, LEV, HERFL, REINS, ROA, CHGNPW, LONGTAIL, JUNK, CASH, and STK. The definitions of SIZE, LEV, HERFL, REINS, and ROA are provided in Appendix C. The definitions of other variables are provided below: CHGNPW: the difference between the net written premiums in this period and in the prior period, scaled by lagged net written premium LONGTAIL: net premiums written (NPW) in long-tail lines of insurance divided by total NPW. We include auto liability, other liability, farm owners/homeowners /commercial multiple peril, medical malpractice, workers compensation, aircraft, and boiler and machinery as long-tail lines. ROA: the ratio of net income to end-of-year total asset JUNK: risky bond investment divided by invested assets CASH: cash divided by invested assets STK: the ratio of equity investment divided by total invested assets We compute the rolling average of FVCS over three years (from year t-2 to t) to increase the likelihood that our measures capture true franchise value: FVi ,t 1 0 FVi,CSt 3 2 (D2) 27 References A.M.

Definitions are provided in Appendix C. Panel B reports the correlations between all the variables. Panel C reports time series averages of firm characteristics across insurer deciles sorted by insurer franchise value in the same period.

The dependent variable is ROA. First, we measure franchise value using the residual terms in the regression of Best Ratings on insurer characteristics (regression-based FV). Next, we look at whether firms without franchise value perform less well. We use a dummy variable, YOUNG, to identify such firms. Third, we perform the analysis for insurance groups. The specific model used for the panel data includes fixed firm and fixed time effects and assumes cross-sectional and time-series dependence in the residual term (Petersen, 2009).
