Audit Committee Financial Experts: A Closer Examination Using Firm Designations, Joseph V. Carcello, Cw Hollingsworth, Terry L. Neal

Joseph V. Carcello

The Sarbanes-Oxley Act (SOX) requires the disclosure of whether the audit committee has a financial expert. We examine disclosures related to audit committee financial experts (ACFEs) in the first year that this disclosure requirement is in effect. We find that virtually all companies disclose whether an ACFE is on the audit committee, although the transparency of the disclosure regarding the ACFE’s background is limited. We also find that most ACFEs do not have a background in accounting or finance, although there are notable differences between stock exchanges on this dimension. In addition, we find that companies designate ACFEs who would …

Estimation Of Large Insurance Losses: A Case Study, Tine Buch-Kromann

Journal of Actuarial Practice (1993-2006)

This paper demonstrates an approach to analyzing liability data recently developed by a Danish insurance company. The approach is based on a Champernowne distribution, which is corrected with a non-parametric estimator. The correction estimator is obtained by transforming the data set with the estimated modified Champernowne cdf and then estimating the density of the transformed data set by using the classical kernel density estimator. Our approach is illustrated by applying it to an actual data set.

Solvency Of Life Insurance Companies: Methodological Issues, Rosa Cocozza, Emilia Di Lorenzo

Journal of Actuarial Practice (1993-2006)

The paper deals with solvency assessment for life insurance business; some methodological issues concerning the solvency of life insurance companies, particularly connected to the investment risk, are suggested. Considerations about the technical equilibrium of an insurance portfolio and the financial regulation lead to a dynamic system involving risk measure and solvency assessment. The formal model is applied to a life annuity cohort in a stochastic context in order to exemplify the potential of the model, especially referred to the need to frame solvency assessment in a dynamic perspective.

A Note On The Instability Of The Unprojected Individual Level Premium Cost Method, Pierre Devolder, Valerie Goffin

Journal of Actuarial Practice (1993-2006)

We compare the unit credit and the unprojected individual level premium cost methods in a continuous time environment and show that the latter may produce unstable contribution rates in a dynamic environment. Specifically, assuming there are no unfunded liabilities, we prove that the unprojected individual premium cost method may produce non-bounded contributions if benefits change too close to the normal retirement age.

Consistent Assumptions For Modeling Credit Loss Correlations, Jan Dhaene, Marc J. Goovaerts, Robert Koch, Ruben Olieslagers, Olivier Romijn, Steven Vanduffel

Journal of Actuarial Practice (1993-2006)

We consider a single period portfolio of n dependent credit risks that are subject to default during the period. We show that using stochastic loss given default random variables in conjunction with default correlations can give rise to an inconsistent set of assumptions for estimating the variance of the portfolio loss. Two sets of consistent assumptions are provided, which it turns out, also provide bounds on the variance of the portfolio's loss. An example of an inconsistent set of assumptions is given.

On Some Risk-Adjusted Tail-Based Premium Calculation Principles, Edward Furman, Zinoviy Landsman

Journal of Actuarial Practice (1993-2006)

This paper explores two tail-based premium calculation principles, the tail standard deviation (TSD) premium and the tail conditional expectation (TCE) premium, in their risk-adjusted and unadjusted forms. They are risk-adjusted using so-called distortion functions. We prove that the proportional hazard (PH) risk-adjusted TCE premium is larger than the unadjusted TCE premium. Additionally, given a risk distribution with location and scale parameters, we prove that the PH risk-adjusted TCE premium reduces to the unadjusted TSD premium.

Bayesian Analysis Of A Health Insurance Model, Helio S. Migon, Edison M.O. Penna

Journal of Actuarial Practice (1993-2006)

We consider the problem of determining health insurance premiums based on past information on size of loss, number of losses, and size of population at risk. The size of loss and the number of losses are treated as mutually independent random variables. The number of losses is assumed to follow a Poisson process, and the loss sizes are independent and identically distributed non-negative random variables, and the population at risk is assumed to follow a non-linear growth model. An expression for the premium is obtained through maximization of the insurer's expected utility under a Bayesian model. The parameter estimation process …

Bayesian Analysis Of Insurance Losses Using The Buhlmann-Straub Credibility Model, Abraham J. Van Der Merwe, Kobus N. Bekker

Journal of Actuarial Practice (1993-2006)

We propose a Bayesian analysis to develop credibility estimates of the well known Biihlmann-Straub model. We describe simple numerical methods to obtain exact posterior distributions and predictive densities under this model. These distributions are obtained through Monte Carlo simulations that generate independent samples from the joint posterior distribution. Our methods are therefore preferable to methods such as Gibbs sampling, which generates dependent samples from the joint distribution. The methods discussed also can be extended to more complicated credibility models.

Analysis Of An Insurance Risk Model With Thinning Dependence And Common Shock, Lai Mei Wan, Kam Chuen Yuen, Wai Keung Li

Journal of Actuarial Practice (1993-2006)

We consider a continuous-time insurance risk model with m dependent classes of business with dependent claim number processes due to thinning dependence and a common shock. The impact of the dependence is studied via the adjustment coefficient. The case m = 2 is investigated analytically for exponential claim distributions and via simulation for non-exponential claim distributions.

Do Option Markets Substitute For Stock Markets?, Tom Arnold, Gayle Erwin, Lance Nail, Terry D. Nixon

Finance Faculty Publications

Using a sample of cash tender offers occurring between 1993 and 2002, we find evidence that the options market has become the preferred venue for traders attempting to profit on anticipated announcements. Options offer advantages relative to stocks. Traders gain leverage by trading in options and multiple options contracts on an individual stock. The results of our study indicate that a substitution effect does exist. Abnormal volume in the option market replaces abnormal volume in the stock market prior to cash tender offer announcements, and this abnormal option volume precedes abnormal stock volume for targets with or without traded options.

Corporate Governance, Public Accounting Firm And Multinational Corporation: The Us Sox Act Perspective, Marc Massoud, Eunsup Daniel Shim

WCBT Faculty Publications

The purpose of this paper is to review US corporate governance systems and to highlight the mandated roles of audit committee and external auditor within the SOX Act. In addition, it discusses requirements and implications of the SOX Act for the foreign accounting firms and multinational corporations. Finally this paper provides a perspective on improvement of corporate governance and financial integrity. In order to regain trust from the financial market, the SOX Act mandates (1) to improve auditor’s independence by reducing conflicts of interest; (2) to increase corporate financial reporting responsibility by requiring a CEO or a CFO certify accuracy …

Spatial Distribution Of Frequency And Severity Of Water Claims In California, Gurbhag Singh, Max Tang, Don Mcneill, Lyn Hunstad

Journal of Actuarial Practice (1993-2006)

We examine the frequency and severity of water loss claims for homeowners insurance across the state of California for the experience years 2000, 2001, and 2002. The spatial distribution patterns of frequencies and severities are mapped and analyzed at the zip code level. The maps reveal the pockets of high frequencies and severities. The information provided in this paper will assist actuaries and policy makers in their quest to set accurate rates for homeowners insurance.

Pricing Insurance Policies With A Distribution-Free Financial Pricing Model, Min-Ming Wen

Journal of Actuarial Practice (1993-2006)

The highly skewed and heavy tailed distributions used to model insurance losses (claims) raise a concern about the validity of the applications of the capital asset pricing model (CAPM) to insurance pricing when market risks are essential. This paper provides an alternative pricing model, called the Rubinstein-Leland model, which can be used to price insurance contracts. The Rubinstein-Leland model has a distribution-free feature that can fully capture the asymmetry embedded in insurance losses. Thus, this model is better able to derive fair prices for insurance policies than is the CAPM.

Bivariate Archimedean Copula Models For Censored Data In Non-Life Insurance, Michel Denuit, Oana Purcaru, Ingrid Van Keilegom

Journal of Actuarial Practice (1993-2006)

We describe a methodology based on Archimedean copulas for analyzing nonlife insurance data with censoring present. Specifically, we propose a graphical selection procedure for the nonparametric estimation of the generator. An actual loss-ALAE data set is used for the numerical illustrations and for comparisons of our approach to a few others.

Accounting Restatements: Are They Always Bad News For Investors?, Dan Segal, Jeffrey L. Callen, Joshua Livnat

Research Collection School Of Accountancy

This study investigates a large sample of financial statement restatements over the period 1986-2001, and compares restatements caused by changes in accounting principles to those caused by errors. Typically, investors perceive restatements as negative signals due to three potential reasons: (a) the restatement indicates problems with the accounting system that may be manifestations of broader operational (and managerial) problems, (b) the restatement causes downward revisions in future cash flows expectations, and (c) the restatement indicates managerial attempts to cover up income decline through “cooking the books.” We provide evidence that market reactions to restatements due to errors are generally negative. …

Impact Of Gender And Ethnic Composition Of South African Boards Of Directors On Intellectual Capital Performance, Jean-Luc Wolfgang Mitchell Van Der Zahn

Research Collection School Of Accountancy

This study examines the association between the gender and ethnic composition of boards of directors and firm performance in a transitional nation. In contrast to prior research that largely focuses on firm performance within a financial context, this study concentrates on intellectual capital performance. Using data collected from 84 South African, empirical results indicate a positive association between the percentage of female and non-white directors on the board and a firm’s intellectual capital performance. Additional analysis shows the designation of female directors as an insider has a negative effect of intellectual capital performance. Designation of female and non-white directors as …

Semi-Strong Form Market Hypothesis: Evidence From Cnbc's Jim Cramer's Mad Money Stock Recommendations, Elizabeth Dodson

Inquiry: The University of Arkansas Undergraduate Research Journal

Mad Money has become one of the most popular shows on CNBC. The host, Jim Cramer, has an outlandish style and personality that viewers find intoxicating. Cramer's goal for the show is to make people money. Does he succeed? This paper finds that investors can expect to gain above-average, risk adjusted returns by following Cramer's stock recommendations and trading accordingly. These findings challenge the semi-strong form market hypothesis. According to this hypothesis investors should not recognize gains trading on public information since it states that the market has already adjusted prices for that information. It also contributes to current literature …

The Essential Role Of Securities Regulation, Zohar Goshen, Gideon Parchomovsky

All Faculty Scholarship

This Article posits that the essential role of securities regulation is to create a competitive market for sophisticated professional investors and analysts (information traders). The Article advances two related theses-one descriptive and the other normative. Descriptively, the Article demonstrates that securities regulation is specifically designed to facilitate and protect the work of information traders. Securities regulation may be divided into three broad categories: (i) disclosure duties; (ii) restrictions on fraud and manipulation; and (iii) restrictions on insider trading-each of which contributes to the creation of a vibrant market for information traders. Disclosure duties reduce information traders' costs of searching and …

Under-Pricing And Long-Run Performance Of Initial Public Offerings In Developing Markets, Sze Wei Daniel Ong

Dissertations and Theses Collection (Open Access)

The transition from being a private company to a public one is one of the most important events in the life of a firm. It is also one of particular interest to institutional investors, and the transition is facilitated through the initial public offering (IPO) process. The IPO provides a fresh source of capital that is critical to the growth of the firm and provides the founder and other shareholders such as venture capitalists a liquid market for their shares. From an institutional investor's perspective, the IPO provides an opportunity to share in the rewards of the growth of the …

Agency Activism As A New Way Of Life: Administrative Modification Of The Internal Revenue Code Through Limited Issue Focused Examinations, W Edward Afield

Faculty Publications By Year

In the name of increasing efficiency and better utilizing limited resources, the IRS has begun to adopt audit policies that overly favor taxpayers and greatly hinder the IRS’s ability to perform thorough audits. Highlighting this trend is a relatively new audit technique used by the Large to Mid-Size Business Division (LMSB), known as the Limited Issue Focused Examination (LIFE) Process. Under LIFE, the LMSB has attempted to involve taxpayers in the audit process by sharing responsibility for timely completion of the audit and has attempted to streamline the audit by reducing the scope of issues examined and applying materiality thresholds …

Tracing, Peter B. Oh

Articles

Tracing is a method that appears within multiple fields of law. Distinct conceptions of tracing, however, have arisen independently within securities and remedial law. In the securities context plaintiffs must trace their securities to a specific offering to pursue certain relief under the Securities Act of 1933. In the remedial context victims who trace their misappropriated value into a wrongdoer's hands can claim any derivative value, even if it has appreciated.

This article is the first to compare and then cross-apply tracing within these two contexts. Specifically, this article argues that securities law should adopt a version of the rules-based …

Dynamics Of Energy Consumption, Safdar Khan

Safdar Khan

Extract:
Dynamics of Energy Consumption Pakistan has been facing severe imbalances in energy demand and supply for the last couple of decades. During early 1980s domestic supply of energy was fulfilling almost 86 percent of total domestic energy demand; a gap of 14 percent was being filled by imports. However, the demand – supply gap started increasing since then and reached to almost 47 percent by the year 2000 (see Figure S2.1).
