On a rank-order test for the equality of probability of an event

Abstract

The following situation is considered. A fixed number (= n) or sequence of independent trials T ₁ T ₂,…, T _n is given, and in each of these an event E mayor may not occur, It is further observed that the event E occurs a total of k times amongst the n trials T _i , (i = l,…, n). It is then required to test the hypothesis H ₀ that the probability of the occurrence of E is constant from trial to trial, i.e. H ₀ is the hypothesis: p ₁ = p ₂ = ? = p _n = p, if p _n (i = 1, …, n) represents the probability that E occurs on the ith trial.     

Internationalizing audit education

Audit education is typically offered only to accounting majors. We argue that auditing provides a way of thinking that could serve as a framework for an accounting curriculam. We describe two parts of a course content that could be incorporated into an existing auditing course or a begining accounting course. The first section emphasizes accountability; the second emphasizes the role of the auditor in the accountability process. The concepts are best taught within an international paradigm that permits examination of various institutional environments.     

Pricing Term Insurance in the Presence of a Family History of Breast or Ovarian Cancer

Abstract

We estimate the increased mortality and term life insurance costs for women who have a family history of breast or ovarian cancer. Using data from the medical literature on age-specific and family history-specific incidence rates, we develop double-decrement models to evaluate the actuarial impact of breast cancer and ovarian cancer in the family. We also calculate the increased mortality and term insurance costs for women who test positive for the BRCA1 or BRCA2 gene mutation. We find that the type of affected relative and her age at onset of the disease are key underwriting factors. We find substantial mortality increases (up to 100%) for women with two relatives with cancer and women with a first-degree relative who developed cancer at an early age. Mortality increases for women with the BRCA gene mutation reach 150%. While some females with a family history of cancer can be accepted at standard rates, others may need to be quoted substandard rates, depending on the underwriting policy of the company. Females with the gene mutation can possibly be accepted at a rate that incorporates a severe mortality surcharge.     

Some generalized distributions based on Stacy's generalized gamma distribution

Abstract

The generalized gamma distribution having the density function was introduced by Stacy (1962), who studied some of its properties. As observed by Stacy, many standard distributions are special cases of (1). For example d=p=1 gives the exponential, p=1 gives the gamma p=1 and d=n/2 (n is a positive integer) gives the chi-squared, and d=p gives the Weibull distribution. Furthermore, certain functions of a normal variable— viz., its positive even powers, its modulus, and all positive powers of its modulus, have Stacy's gamma form.     

Closing the Ledger

Using a unique, hand‐collected final dataset of 57 management buy‐outs in distress, this paper analyses the determinants of bankruptcy costs under the UK's receivership regime. We show that the direct costs of receivership consume a significant percentage of the receivership proceeds, with mean receivership costs equal to 30% of receivership proceeds. Importantly we find that while the average length of receivership was 3.0 years, 95% of repayments are made on average within 1.9 years. Our findings do not support the argument that multiple lenders create inefficiencies resulting in significantly lower secured creditor recovery rates. However, when there are multiple secured lenders, the senior secured lender gains at the expense of other secured creditors. We find that receivership costs are positively related to the proportion of secured debt repaid and that, consistent with the presence of a scale effect, the relative significance of receivership costs declines as firm size grows. Receiverships last longer the larger the amount of debt owed to the secured lenders.     

The Relationship between Earnings,Funds Flows and Cash Flows: Evidence for the UK

Recent UK information content studies have provided evidence of a significant relationship between earnings and share prices, as in the US, but have also identified an apparent lack of information content for operating cash flow, which is in marked contrast to findings from US research. This paper provides direct evidence on the relationship between earnings, funds flows and cash flows in the UK during the period 1965–84, using tests of association and predictive tests based on a research methodology applied by Bowen, Burgstahler and Daley (1986) to US data. The results provide UK evidence on the contemporaneous and predictive relationships between measures of earnings, funds flows and cash flows which are generally consistent with the US findings of Bowen et al. and which do not support the view that earnings in the UK are superior to cash flows as predictors of future cash flows.     

Costs of Accounting to Lenders: Canadian Evidence

Do new accounting pronouncements impose costs on firms with accounting-based restrictions in their public lending agreements? Previous studies have not found significant, adverse share price reactions to such pronouncements. This paper posits that management is concerned with the total costs of the monitoring policies used for reporting to lenders, and that share price reactions are likely to comprise only a small portion of those costs. The episode of mandatory lease capitalisation in Canada is used to test some predictions that are consistent with this expanded view of the costs of accounting to lenders. Lessees ‘public lending agreements were examined to see if they stipulated restrictions based on accounting numbers; and, if they did, whether the constraints were based on GAAP (generally accepted accounting principles) or TAP (tailored accounting principles). The evidence strongly supports the hypothesis that there are costs of accounting to lenders; but these costs are unlikely to be observed by researchers who look only for adverse share price reactions to mandated accounting changes. It also indicates that Canadian standards setters were sensitive to lessees’ accounting costs.     

Financial Ratio Covenants in UK Bank Loan Contracts and Accounting Policy Choice

The attitudes of lending bankers to the use of restrictive ratio covenants in loan contracts are of importance to both corporate management and accounting policy makers. Such attitudes also underly research linking costly contracting with accounting policy choices. This paper reports a survey of 33 UK lending bankers. It analyses their views on (a) the extent of ratio covenants in UK bank loan contracts and factors with which their presence is most likely to be associated; (b) costs that may be imposed on borrowers violating such covenants or expecting to do so; and (c) the ability of borrowers to avoid such costs by appropriate choice of accounting methods. Respondents indicated that ratio covenants are widely used, particularly for loans in excess of £1 million and with companies that are relatively highly geared. ‘High cost’ penalties such as loan acceleration are most likely to be adopted where no prior warning has been given of a covenant breach. Where prior warning has been given, or where a breach is due to an acquisition, waivers and contract renegotiation are more likely responses. Breaches caused by new SSAPs cause few real costs to borrowers, while just under 60% of respondents indicate they may take no action in response to a voluntary accounting method change.
