Loss Reserves and the Employment Status of the Appointed Actuary

Abstract

Property/casualty (P/C) insurers are required to establish loss reserves for unpaid losses at the time that the loss has occurred or is reasonably expected to have occurred. We examine factors that may impact the accurate setting of loss reserves. These include the level of rate regulation faced by the insurer and the incentives to underestimate or overestimate reserves to improve financial ratios or improve solvency scores, to reduce earnings, to defer taxes, or to smooth earnings volatility in order to meet shareholder expectations. The employment status of the Appointed Actuary, that is, whether the Appointed Actuary is an employee of the firm or a consultant, may also impact reserve accuracy. Using a variety of regression models with data from 1995 to 2010, we examine the impact of these factors on the accuracy of reserves posted by Canadian P/C insurers. Our results provide no evidence of systematic differences in the magnitude or direction of loss reserve errors between insurers that use company actuaries versus those that use consultant actuaries. However, we find that for both consultant and company actuaries positive reserve errors are associated with increases in global stock market returns and decreases in unanticipated inflation. The insurance market cycle impacts reserve errors for company actuaries and not consultant actuaries. As well, our results indicate that as the proportion of short-tailed business increases in a company, consultant actuaries are more likely to over-reserve. Similar to many previous studies using U.S. data, we do not find strong evidence regarding insurers’ incentives to deliberately overstate or understate reserves: Loss reserves are relatively unbiased estimates of the true losses paid. Thus these findings should be welcome news to the actuarial profession in Canada and to the prudential regulator: The Appointed Actuary, regardless of employment status, provides objective and unbiased estimates of insurers’ largest liability.     

Open‐Market Stock Repurchases by Insurance Companies and Signaling

The signaling hypothesis of share repurchases implies that management uses repurchases to signal either that their firm's future operating performance will improve or that shares of their stock are simply underpriced by the market. This study examines which of the two interpretations can better explain open‐market share repurchase programs announced by insurance companies. We find no evidence that future‐operating performance of insurers improves following the repurchase announcement. In addition, changes in future operating performance cannot explain the announcement‐period abnormal return. Instead, the stock undervaluation prior to the repurchase announcement can significantly explain the announcement‐period abnormal return, particularly for life insurers. Overall, our results suggest that the positive market reaction to insurers’ open‐market share repurchase announcements is due to the stock undervaluation by the market, but not due to positive information content about future operating performance conveyed in the repurchase announcement.     

The Use of Dynamic Financial Analysis to Determine Whether an Optimal Growth Rate Exists for a Property-Liability Insurer

Prior research on the aging phenomenon has demonstrated that new business for property‐liability (P‐L) insurers generates high loss ratios that gradually decline as a book of business goes through successive renewal cycles. Although the experience on new business is initially unprofitable, the renewal book of business eventually becomes profitable over time. Within this context, insurers need to manage their exposure growth in order to maximize long run profitability. Dynamic financial analysis (DFA), a relatively new tool for P‐L insurers, utilizes Monte Carlo simulation to generate the overall financial results for an insurer under a large number of scenarios. This article uses a publicly available DFA model—along with the estimated market value of an insurer, based on 1990–2001 data for stock P‐L insurers and underlying financial variables—to determine optimal growth rates of a P‐L insurer based on mean–variance analysis, stochastic dominance, and constraints on leverage.     

Evidence on Risk Changes Around Audit Qualification and Qualification Withdrawal Announcements

Qualifications to an audit report may provide the basis for an auditor's claim that the user was warned about an unusual risk. If audit qualifications highlight changes in firm risk that are material, then the announcement of a qualification should be associated with an increase in the risk of the affected firm. In this paper, we test this proposition. Our initial tests do not detect a shift in systematic risk around qualification announcements; however, subsequent analysis shows that firms announcing recurring material uncertainties have higher levels of systematic risk than firms announcing initial qualifications. Furthermore, we document a significant decrease in systematic risk for firms publicly announcing qualification withdrawals. These results are consistent with announcements of qualification withdrawals providing more timely information to capital market participants than announcements of qualification issuances, which are more likely to have been pre-empted by alternative sources of information. Our findings also indicate that unsystematic, or firm-specific, risk changes significantly around qualification and withdrawal announcement dates. Although systematic risk is of primary importance to investors, information regarding company-specific risk may assist other outside users (i.e., lenders, regulators, employees, rating agencies, etc.) in evaluating a given firm's ability to satisfy its existing contracts. In total, this paper provides evidence that may be useful to many external parties regarding the association between the material uncertainties that are highlighted in audit reports and changes in firm risk.     

Market Risk,Interest Rate Risk,and Interdependencies in Insurer Stock Returns: A System‐GARCH Model

We examine market risk, interest rate risk, and interdependencies in returns and return volatilities across three insurer segments within a System‐GARCH framework. Three main results are obtained: market risk is greatest for accident and health (A&H) insurers, followed by life (Life) and property and casualty (P&C) insurers; interest rate sensitivity is negative and greatest for Life insurers; and interdependencies in returns are significant with the magnitude being strongest between P&C and A&H insurers. The implication is that greatest diversification benefits arise between Life and the other segments of the insurance industry. Market risk and interest rate risk for diversified firms are smaller than those for nondiversified firms for both product and geographic diversification.     

Independently Certified Industry-specific Disclosures to the Capital Market: The JORC Code in the Australian Mining Industry

We investigate compliance with the Australian JORC Code for reporting mineral resources and ore reserves, the quality of the disclosure, and its impact on the capital market. The compliance and quality assessment is conducted by two experienced geologists who find that while the overall reporting quality improved after the 2012 revisions to the Code, they disagree on the extent of improvement. This reflects the uncertainties involved and the difficulty in interpreting the reports. Both geologists agree that the greatest improvement is seen in early-stage projects, consistent with the expectation that there are more uncertainties surrounding these, and the additional information disclosed under the 2012 JORC Code appears to assist in reducing the uncertainties to some extent. The capital markets study shows that JORC announcements have a significant impact on investors’ assessments of firm value, and that the announcement impact is higher after the 2012 revisions designed to strengthen the disclosure requirements. This is consistent with post-2012 JORC reports conveying higher information content. There continues to be information leakage prior to announcement date. Further tests show a widening of bid–ask spreads in the post-2012 period, suggestive of higher information asymmetry. While the probability of informed trading declines for large firms, it remains statistically unchanged for the rest of the sample. The findings reiterate the need for regulators and standard setters to be cognisant of unintended consequences of their decisions. The substantiation process under JORC involves a delay in the release of ‘news’, a ‘chilling’ effect with larger announcement effects.     

An Investigation of the Short‐Run and Long‐Run Stock Returns Surrounding Insurer Rating Changes

We find that stock returns move in the direction of insurer rating changes in the 12‐month period prior to the announcement. There is an additional stock price response following the announcement of a downgrade, but no response to upgrade announcements. The reaction to a downgrade is more pronounced when it involves a smaller insurer, when it spans multiple levels, or when it is a threshold downgrade. Returns are significantly more negative during the 12 months leading up to a downgrade announcement during the financial crisis (2008 and 2009) compared to other sample years.     

Early Movers Advantage? Evidence from Short Selling during After‐Hours on Earnings Announcement Days

We examine short sellers’ after‐hours trading (AHT) following quarterly earnings announcements released outside of the normal trading hours. Our innovation is to use the actual short trades immediately after the announcements. We find that on these earnings announcement days, there is significant shorting activity in AHT relative to shorting activity both during AHT on nonannouncements days and during regular trading sessions around announcements. Short sellers who trade after‐hours on announcement days earn an excess return of 0.82% and 1.40% during before‐market‐open (BMO) and after‐market‐close (AMC)sessions, respectively. The magnitude of these returns increases to 1.48 (3.92%) for BMO (AMC) earnings announcements with negative surprise. We find that the reactive short selling during AHT has information in predicting future returns. Short sellers’ trades have no predictive power if they wait for the market to open to trade during regular hours. In addition, we find that the weighted price contribution during AHT increases with an increase in after‐hours short selling. Overall, our results suggest that short sellers in AHT are informed. Our findings remain robust using alternative holding periods and after controlling for macroeconomic news announcements during BMO sessions.     

Forestalling capital regulation or masking financial weakness? Evidence from loss reserve management in the property–liability insurance industry

This study examines the extent to which capital thresholds induce insurers to strategically exert accounting discretion to forestall regulatory actions. Using a sample of US property–liability insurers during 1994–2009, we find that when managing their claim loss reserves, the average insurers are insensitive to the pressure of capital regulation as measured by the distance of their RBC ratio to the action threshold. Yet, when the insurers are virtually partitioned by their reserving tendency, the effect of regulatory pressure is significantly related to the downward reserve bias in the under-reserving insurer cohorts. This finding continues to hold even after we utilize the number of ratio violations in the insurance regulatory information systems to purge the financial weakness effect embedded in the distance to RBC bound ratio. Hence, our empirical evidence suggests that insurers that are about to trigger the regulatory threshold will have the incentives to understate their loss reserves to preclude the impending authorized preventive actions. Finally, our analyses also shed light on the heterogeneity of incentives to managing loss reserves among over- and under-reserving insurers.     

Funding conditions and insurance stock returns: Do insurance stocks really benefit from rising interest rate regimes?

We examine funding conditions and U.S. insurance company stock returns. Although constrained funding conditions, signaled by restrictive Federal Reserve monetary policy, correspond with increases in the future payouts of fixed‐income securities held by insurance firms and potentially provide value through the liability side of insurer balance sheets, they also decrease the values of securities currently held in insurer portfolios. Prior research finds that restrictive policy has a negative effect on equity returns in general. Our results suggest the negative impacts of constrained funding environments outweigh the potential positives, as insurance company stock returns are significantly lower during periods of constrained funding. This effect varies within a given funding state and also across insurer type. The effect is strongest during the first 3 months of a constrained funding environment and for life and health insurers—insurer types with longer portfolio durations. For property and liability (P&L) insurers, lower stock return performance only exists in the first 3 months of a constrained funding environment. In the subsequent months, P&L insurers actually have higher stock returns during constrained periods, consistent with their typically shorter duration asset portfolios, which are more quickly rolled over into new higher‐yielding securities.     

The market valuation of M&A announcements in the United Kingdom

This paper investigates the short-term market reaction to UK acquirers announcing domestic and foreign mergers and acquisitions (M&As) from 2000 to 2010. We define acquirers as value, moderate and glamour acquirers based on equally weighted market-to-book terciles. We find that value acquirers outperform glamour acquirers during and after the M&A announcement. We also focus on the impact of institutional ownership and find that higher domestic, foreign and total institutional ownership leads to lower market reaction to M&A announcements. We also find that long-term institutional investors lead to a higher post-announcement market performance. Finally, we find that greater domestic institutional ownership mitigates the typical poor short-term performance following M&A announcements of glamour acquirers.     

The attenuation effect of social media: Evidence from acquisitions by large firms

We examine the role of social media in firm acquisitions. Twitter utilizes the “push” technology that allows firms to reduce information asymmetry by disseminating news to a broader set of investors in a timely manner. Using hand collected acquisition announcements from Twitter covering the period from 2009 to 2012, we find that the acquirer size is a main determinant of disclosing acquisition announcements on Twitter. Large acquirers announce their acquisitions on Twitter and, as a result, are able to attenuate the anticipated negative market reaction at acquisition announcement. We find no evidence that the attenuation effect of announcing acquisitions on Twitter subsequently reverses or that announcing acquisitions on Twitter is positively associated with pre-announcement earnings management. Overall, our results suggest that Twitter has become an important investor relation channel for major corporate events such as acquisition announcements and that large acquirers can use this new channel to enhance stability in their stock prices.     

Persistence of announcement effects on the intraday volatility of stock returns: Evidence from individual data

We analyze the persistence effects in the empirical relationship between announcement releases and return volatilities of four major companies of the French stock market using high frequency data over the period 1995–1999. Besides its institutional stability, this sample period avoids the econometric difficulties inherent to simultaneous news arrivals. Our approach contributes to the relevant literature in that we focus on individual stock volatilities rather than indices, we distinguish firm‐specific and macroeconomic announcements, and we endogenize both the durations of announcement effects and the response patterns of equity prices. We find that our individual volatilities are affected by a systematic market effect, calendar effects, announcements related to the firms’ macroeconomic environment and announcements related to the firms’ and their competitors’ strategic dealings and commercial outcomes. We find evidence that all volatility responses are gradual with persistence horizons ranging from one to three hours, revealing a significant degree of inefficiency of the French stock market over the period. This inefficiency can be viewed as a breeding ground for the implementation of more performant informational and trading systems that allowed markets to move towards more efficiency.     

The Effects of Stock Repurchases on Rival Firms

This paper investigates the stock price behavior of rival firms in the same industry as firms announcing stock repurchase tender offers. Using a sample of 134 repurchase announcements, I find that rival firms on average realize insignificant announcement period abnormal returns. Negative rival stock price performance is detected over longer intervals surrounding the announcement period and for a subset of announcements which ex ante were identified as most likely to affect rivals. This evidence, however, is statistically weak and does little to alter the overall conclusion that the information in repurchase announcements is primarily firm-specific.     

Exposure Triggers and Allocation Methods: Learning Lessons From Prior Court Rulings

This study provides a review of some of the major court rulings that have shaped and continue to shape the commercial general liability (CGL) market. The evolution of the concepts of "triggers" and allocations systems is examined to gain a perspective on the way in which courts reinterpret contract language to apply to new and emerging exposures. A review of the issues impacting the CGL provides valuable insights into the way court rulings can create a significant impact in the insurance market. A stream of court decisions provides the backdrop for today's challenges, including the reemergence of asbestos claims. The study also fills a gap in the literature related to the crisis in the CGL marketplace and changes in the pricing, regulation, and solvency of insurers operating in those lines. As old risks continue to evolve and new risks emerge, courts have begun to reinterpret liability contracts in much the same way as they reinterpreted contracts with regard to pollution and products in the 1970s and 1980s. Recent rulings related to asbestos and environmental liability underscore the importance of these issues in today's marketplace. By reviewing these events related to the CGL policy, insurers, insureds, and regulators may gain a new perspective on the importance of developing a clear standard wording that will be consistently interpreted in light of new exposures.     

Employee Downsizing Strategies: Market Reaction and Post Announcement Financial Performance

Empirical studies have generally reported insignificant market reactions to employee downsizing. In an effort to reconcile ongoing layoffs with inconclusive empirical results, we segregated our sample by downsizing strategy and examined employee layoff announcements made by Fortune 500 firms during the 1993–1995 period. Unlike previous studies, we find a positive market reaction for layoff announcements related to revenue refocusing. Market reaction with respect to layoff announcements involving cost cutting was insignificant while weak evidence was found for a negative market reaction to layoffs related to plant closings. Consistent with the market reaction, post announcement analysis revealed that downsizing in conjunction with revenue refocusing (plant closing) improved (reduced) firm financial performance and that revenue refocusing firms significantly outperformed cost cutting and plant closing firms over the three–year post announcement period.     

Stock Market Reactions and Information Transfer Due to Financial Instability in the Life Insurance Industry

ABSTRACT: This study examines the stock market reactions and information transfer effects due to financial instability for four life insurance companies that eventually failed or were taken over by regulators. The four companies were First Executive Corporation, First Capital Holdings Corporation, Monarch Capital Corporation, and Mutual Benefit Life Insurance Company. In general, significant negative capital market responses were found after a company released an announcement regarding financial instability. Information transfer effects of a negative announcement by one insurer were not found to have a significant impact on the other insurers. This study complements past studies of contagion effects within the insurance industry.     

PROFITABILITY, EARNINGS ANNOUNCEMENT TIME LAGS, AND STOCK PRICES

This research addresses (1) whether firms with lower (hgher) than expected earnings fgures released those figures to the public later (earlier) than expected and (2) whether there is a reaction by the capital market to the timing of the earnings announcement. The results indicate that later than expected earnings announcements are likely to contain worse news than early announcements. Also the stock returns of late reporting firms appear to be lower than that of early reporting firms in the days surrounding the earnings announcement date.     

Pflichthaftpflichtversicherung für Hersteller von Medizinprodukten – überfällig oder überflüssig?

Given actual legislative initiatives in the German Bundestag the question arises as to whether in the interest of patient safety-compulsory liability insurance for producers of medical devices should be implemented. At present, these proposals for reform are incompatible with the constitutionally-guaranteed principles of professional freedom and freedom of contract. Furthermore, it is questionable whether compulsory liability insurance would in fact improve the situation of patients taking into consideration the insurer’s status and possible release from obligation. Should compulsory liability insurance pass constitutional review due to new factual findings in the future, a direct claim against the liability insurer is not advisable. A possible victim compensation fund is not to be financed by the producers or their liability insurers.     

The Information in Management's Expected Earnings Report Date: A Day Late, a Penny Short

Since 1995, managers of thousands of firms have voluntarily disclosed the expected date of their firm's next quarterly earnings announcement to Thomson Financial Services Inc. These disclosures are approximately 500% more accurate than the simple time–series expected report dates used in prior accounting research. These disclosures are also informative. On average, managers who miss their own expected date eventually report earnings that fall about one penny per share below consensus forecasts for each day of delay. Investors respond by sending the price of late–announcing stocks down at the missed expected report date and continue to send them down as the reporting delay lengthens, consistent with our "day late, penny short" result. Despite this, we find that the market response at the time earnings are announced still depends on whether the announcement is early, on time, or late relative to the firm's own expected report date.
