Measuring the Comparability of Company Accounts Conditionally: A Research Note

Comparability indices summarize the level of comparability between companies at a national and international level, an issue of importance to investors, regulators, and standard setters. Comparability indices can identify areas where comparability is low and where comparability is deteriorating. Furthermore, they can be used to quantify the extent to which initiatives such as International Financial Reporting Standards (IFRS) are successful in raising comparability between company accounts. Despite past literature emphasizing how factors other than country influence accounting methods used by companies, current comparability indices ignore these other factors. This paper introduces new national and international indices within the T index framework to fill this gap in the literature. Formula for the new national and international indices, and their standard errors, are provided. An example using European data is used to demonstrate the calculations and illustrate the importance of controlling for these firm specific factors.     

Harmony, Statistical Inference with the Herfindahl H Index and C Index

The Herfindahl H index and C index provide measures of harmony of accounting measurement practices by summarizing the extent to which companies use the same accounting practice. While the values of these indices are compared to obtain some idea concerning the relative harmony of accounting practice, standard errors for these estimates are not generally provided. That is, an index is calculated from a sample but no guidance is provided concerning likely values of the index in the population from which the sample was drawn. The present article fills this gap in the literature by providing formulae to estimate the standard error of the H and C indices calculated from a sample. The formulae are illustrated with several examples from the literature to show how conclusions are either enhanced or modified by the addition of these standard errors. It is shown that while both indices are biased, this bias is generally negligible. It is hoped that in future authors will quote not only the value of the index itself but also the standard error so differences between index values (both within and between studies) can be judged as being either significantly different or explainable by sampling variation alone.     

The Measurement of Comparability in Accounting Research

Indices of harmony such as the H, C, I and T indices have been developed and used in the accounting literature to quantify the level of comparability of company accounts. This has led to advances in definitions of comparability as well as empirically quantifying the extent of comparability between actual company accounts. These are important because the general concept of comparability is considered desirable, as highlighted by its inclusion as one of four qualitative characteristics in the framework of the International Accounting Standard Board (IASB). This paper rebuts criticisms of harmony indices in the accounting literature by arguing these criticisms either: (a) apply to old indices but not to newer ones, (b) apply to most empirical accounting research, (c) are based on incorrect or irrelevant assertions, or (d) relate to alternative definitions of harmony. This assists the use and interpretation of harmony indices and advances our understanding of what comparability means. New indices within the T index framework are also proposed by directly comparing company accounts and therefore avoiding the previous requirement to define ‘accounting methods’. A new index R is also proposed to capture international harmony between countries when within‐country uniformity is absent.     

The Measurement of Harmonisation and the Comparability of Financial Statement Items: Within-Country and Between-Country Effects

This paper reports on an analysis of accounting policy choices made by European companies with an international shareholding. The accounting policies analysed in depth in this paper comprise the treatment of goodwill and accounting for deferred taxation. In the paper, the van der Tas comparability index is developed by separating the index into two components relating to the within-country (intra-national) effects of domestic standardisation and the between-country (inter-national) effects of harmonisation. It is shown in this paper that the value of the index may be interpreted as the probability that two companies selected at random will report financial information that is comparable, and that the lowest level of comparability exists when the accounting methods are assumed to be distributed equiprobably over the companies, the outcome of a random selection of accounting policies. The paper also considers the problems of non-disclosure, and a comprehensive ‘disclosure-adjusted’ comparability index is proposed.     

The Impact of Adopting International Accounting Standards on the Harmonization of Accounting Practices

Over the past few decades numerous organizations have been actively participating in the efforts to improve the comparability of financial reporting. Many studies have discussed the benefits and drawbacks of comparability. This study investigated the affect on the harmonization, or comparability, of accounting practices when a sample of companies choose to use international accounting standards (IASs) when preparing financial reports.This study analyzed trends in the I index, a measure of concentration for the use of a particular accounting practice introduced by van der Tas, to determine if the choice of accounting methods by a sample of Swiss companies became more aligned with a sample of companies from three other countries. The study included a control sample of Swiss companies that did not switch from reporting using local Swiss standards during the same time period, 1988 through 1995. Four accounting practices were included; depreciation, inventory, financial statement cost basis, and consolidation practices. The practices used were compared with a sample of companies from three countries; Japan, the UK, and the US.The results indicated that across the 8-year period, the majority of the I indices comparisons were positive and statistically significant. However, the results did not support that these increases were due primarily to the adoption of IASs.     

Measuring the Degree of International Harmony in Selected Accounting Measurement Practices

This research assesses empirically the extent to which selected accounting measurement practices of companies from France, Germany, Japan, the UK and the US are harmonised in the context of major international efforts to enhance the comparability of company financial statements. The findings suggest that significant differences continue in accounting measurement practices between companies originating in each of these countries. The results of the study have important implications for international standard-setters, investors, creditors and those interested in international accounting.     

The information compliance indexes. The illustrative case of income taxes

The adoption of IASB’s standards has represented, in the European Union, an important effort of harmonization towards the financial reporting comprehensiveness, reliability, relevance and comparability. This paper seeks to highlight the importance of Information Compliance Indexes (ICI), based on the accounting standards, as a proxy for reporting quality awareness. This approach is evidenced through an illustrative example about disclosures on deferred taxes, as required by IAS 12. This standard prescribes the accounting treatment for current taxes, deferred assets and liabilities. These issues are usually perceived by stakeholders as indicators of companies’ continuity and potential future returns. Based on non-financial listed companies of Euronext Lisbon regulated market, with reference to the end of fiscal years 2008 and 2012, an information compliance index was performed, based on that accounting standard. Then, this index was regressed with a set of performance and control indicators. Evidences have provided several statistical significant insights, which corroborate the findings that information compliance and disclosure levels depend from several performance and control indicators.     

Valuation with Market Multiples: How to Avoid Pitfalls When Identifying and Using Comparable Companies1

An important part of the market multiple valuation process is selecting companies for comparison that are really comparable to the company being valued. The goal of assessing comparability is to align the relevant value drivers—especially risk and growth—of the comparable companies with those of the company being valued. In this paper, the authors examine the relevant value drivers for commonly used market multiples such as EBIT and EBITDA. They show that, in addition to risk and growth, analysts doing market multiple valuations need to take account of differences in variables such as cost structure, working capital, and capital expenditure requirements when assessing comparability. The authors also show that the degree to which different value drivers are important for assessing the comparability of companies differs across commonly used market multiples. In other words, some multiples are more sensitive than others to changes in certain value drivers. For example, when using a multiple like EBITDA in which certain expenditures (such as capital investments, working capital investments, and some expenses) are not deducted in the calculation of the denominator, assessing comparability based on such expenditures is more important than when using a multiple like free cash flow that deducts that expenditure in calculating the denominator. Or to cite another example, since EBIT and EBITDA make no attempt to reflect income taxes, using income tax cost structures to assess comparability is more important for enterprise value multiples based on these measures than for enterprise value multiples based on “after‐tax” measures of income such as unlevered earnings or free cash flow. In addition, not all multiples control for differences in cost structure, such as cost of goods sold or SG&A. If a multiple is affected by differences in those value drivers, the comparable companies must be similar to the company being valued on that dimension. Finally, the authors show that differences in capital expenditure and working capital requirements can also have large effects on certain multiples; and as a result, such value drivers also must be considered when assessing comparability.     

IFRS fair value measurement and accounting policy choice in the United Kingdom and Australia

This study investigates the use of fair value measurement by 228 listed companies in the UK and Australia around the time of adoption of IFRS from 1 January 2005. We test whether within and between country comparability in policy choices (as measured by T indices) has changed in relation to (a) mandatory and (b) optional use of fair value measurement. Mandatory requirements related to financial instruments (IAS 39) and share-based payments (IFRS 2) have increased comparability, with a weaker effect for biological assets (IAS 41). In relation to the optional use of fair value, comparability increased in relation to property (IAS 16) because some companies discontinued fair value measurement. Under IAS 39, the fair value option for other financial assets and other financial liabilities decreased comparability. Options to use fair value in other areas (intangible assets, plant and equipment and investment properties) are not generally taken up, either for on-going measurement or on IFRS adoption (under the ‘deemed cost’ option). The results suggest a conservative approach and/or lack of incentives to use fair value measurement for most companies. Exceptions include some banks and insurance companies (for other financial assets and liabilities) and companies holding investment properties.     

Sample Selection Bias and Repeat-Sales Index Estimates

Analysis of variations in house values among localities requires reliable house value indices. Gatzlaff and Haurin (1994) indicate that traditional hedonic house value index estimates, using only information from a sample of sold homes to estimate value movements for the entire housing stock, may be subject to substantial bias. This article extends previous work by adapting the censored sample procedure to the repeat-sales index estimation model. Using data from Dade County, Florida, a house value index constructed from a sample of homes selling more than once, rather than all houses in a locality, is found to be biased. The bias is shown to be highly correlated with changes in economic conditions.     

Corporate culture and financial statement comparability

In this paper, I empirically examine the influence of corporate culture on the comparability of financial statements. I predict that firms with strong corporate cultures have less-opportunistic managers, who make homogenous decisions when faced with similar economic events, resulting in greater accounting comparability. For a sample of U.S. companies, I find empirical evidence consistent with this prediction: firms with strong corporate cultures have greater peer- and industry-level comparability. These results are robust to using an entropy-balanced sample, correcting for sample selection bias using Heckman's two-step procedure, and employing different measures of corporate culture strength. Further analysis reveals that sudden CEO turnovers that move firms towards (away from) a stronger corporate culture positively (negatively) influence post-turnover accounting comparability. My results provide new insights on the role of corporate culture for financial reporting.     

Is transfer pricing strictness deterring profit shifting within multinationals? Empirical evidence from Europe

This paper examines the extent to which the introduction and tightening of transfer pricing frameworks deter income shifting strategies by European multinational companies. To do so, we have built an index that measures the transfer pricing framework strictness by host country and year. Then, tax rate differentials are used to capture profit-shifting incentives and are interacted with the strictness index to assess whether the host country's transfer pricing framework impacts profit-shifting behaviour. The index is shown to increase significantly over the sample period, indicating that the scrutiny of related party transactions by European governments has increased over the period 2001–2009. Using a sample of European foreign subsidiaries, the results suggest that the stricter the transfer pricing framework the lower the tax rate difference sensitivity of reported earnings. This indicates that tightening the transfer pricing framework is capable of dissuading multinational companies from shifting profits from higher- to lower-tax countries.     

Bias and Precision of Estimates of Housing Investment Risk Based on Repeat-Sales Indices:A Simulation Analysis

A simulation analysis is reported which examines the bias and precision of estimates of housing investment risk based on small sample indices of housing returns. The trade-off between smoothing bias (due to temporal aggregation in the index) and noise bias (induced by random estimation error) is examined in the housing return total volatility, beta, and autocorrelation statistics of the index returns. The study compares the performance of three different specifications of the repeat-sales index, under assumptions of either an informationally efficient or inefficient housing market, and at two levels of estimation data availability. Findings suggest that regression-based repeated-measures indices may be useful at a more micro-level (e.g., at the neighborhood level or for specific housing types) than has hitherto been employed.     

Are IFRS and U.S. GAAP converging? : Some evidence from People's Republic of China companies listed on the New York Stock Exchange

This research investigates the comparability and convergence of two sets of accounting standards from 1996 to 2002: United States’ Generally Accepted Accounting Principles (U.S. GAAP) and International Financial Reporting Standards (IFRS). The investigation involves a sample of companies from the People's Republic of China (PRC) that are listed on the New York Stock Exchange (NYSE). PRC companies traded on the NYSE generally prepare IFRS financial statements and provide a limited reconciliation to U.S. GAAP, creating a unique quasi-experimental opportunity to examine differences between two sets of accounting numbers produced by two different sets of accounting standards while holding the company constant. Comparability is measured by using Gray's index of comparability, and a set of measures are introduced to capture several dimensions of convergence over time in reported net income, net assets, return on net assets, and earnings per share. The evidence shows lack of comparability, caused largely by the revaluations of property, plant and equipment permitted under IFRS, but not permitted under U.S. GAAP. There is, however, substantial evidence of convergence over time.     

The Construction of Residential Housing Price Indices: A Comparison of Repeat-Sales,Hedonic-Regression,and Hybrid Approaches

This article examines a number of hypotheses that underpin the repeat-sales and hedonic approaches to the construction of housing price indices, as well as the practical problems associated with the implementation of either approach. We also examine a hybrid procedure that combines elements of both the repeat-sales and hedonic-regression techniques. For our sample of individual home sales in Oakland and Fremont California over an 18-year period, repeat-sales methods are subject to sample selection bias; the maintained assumption of time constancy of implicit prices of housing attributes is violated; the repeat-sales estimator is extremely sensitive to influential observations; and the usual method used to correct for heteroskedasticity in repeat-sale housing returns is inappropriate in our sample. Hedonic techniques are better suited to contend with index number problems per se, as they can accommodate changing attribute prices over time. They also appear to give rise to more reliable estimates of price indices, as unusual observations have less effect on estimated price indices. Drawbacks of the hedonic approach include the usual concern with omitted attributes, and their effect on the estimated price index.     

The impact of voluntary audit and governance characteristics on accounting errors in private companies

This paper examines the extent to which the audit and corporate governance characteristics of UK private companies are associated with defective accounting information. Despite the economic importance of private firms, relatively little is known about their financial reporting and governance characteristics. Using a large sample of UK private companies, we examine the effects of voluntary audit, board gender balance and financial expertise on the likelihood of errors occurring in published annual accounts. Our results indicate that audited accounts are approximately half as likely as unaudited accounts to contain errors. In addition to contributing to recent academic research in this field, our findings are likely to be of interest to policy makers, who are considering exempting more firms from mandatory audit. We also find that gender diversity among board members is positively associated with the accuracy of accounting information, though our primary measure of directors’ financial expertise has no significant effect.     

Stock option compensation: impact of expense recognition on performance indicators of non-domestic companies listed in the U.S.

The IFRS 2, Share-based Payment, requires that companies recognize the fair value of employee stock options as an expense. To ascertain the impact recognition will have on companies domiciled in countries subject to accounting standards issued by the IASB’s liaison standard setting partners, this research examines the pro forma stock option disclosures provided in Form 20-F by Australian, British, Canadian, French, German, Japanese, and Irish companies.The findings indicate the average impact of expense recognition on diluted EPS will be approximately 40% and will be material at a 5% level for the majority of the companies. The impact varies significantly by country. On average the annual expense recognized will be approximately 15% of beginning stockholders equity. For the majority of the companies, the charge will represent less than 1% of beginning equity. Again the impact varies significantly by country.The findings indicate that absent requirements that stock compensation expense be recognized, a material upward bias will be reflected in performance indicators of many non-U.S. companies and cross-border comparability will be impaired. Since our analysis is based solely on data for the year 2000 for companies domiciled in seven countries, future research will be needed to ascertain the impact of expense recognition on a broader range of companies reporting under IFRS 2.     

Challenging the reliability of comparables under profit-based transfer pricing methods

Under profit-based transfer pricing methods, the selection of comparable companies is essential if detection of transfer price manipulation is to be reliable. Comparative advantage as embedded in internalisation theory argues that foreign-controlled companies (FCCs) should, in the long run, display greater profitability than domestic-controlled companies. In high-tax host countries, transfer pricing manipulation theory predicts an opposite effect on profitability. Applying a refined set of tests to a large sample of firms operating in a high-tax country such as Italy offers strong support for the internalisation prediction. Furthermore, the analysis of the interquartile range of our measure of profitability indicates that only a low percentage of FCCs would be subject to fiscal enquires, as implied by the Organisation for Economic Co-operation and Development guidelines, under the suspicious of transfer pricing manipulation. These results suggest that current comparability tests are likely to fail the identification of transfer pricing practices in countries where the comparative advantage of FCCs is particularly pronounced and question the reliability of these tests.     

The Stambaugh bias in panel predictive regressions

This paper analyzes predictive regressions in a panel data setting. The standard fixed effects estimator suffers from a small sample bias, which is the analogue of the Stambaugh bias in time-series predictive regressions. Monte Carlo evidence shows that the bias and resulting size distortions can be severe. A new bias-corrected estimator is proposed, which is shown to work well in finite samples and to lead to approximately normally distributed t-statistics. Overall, the results show that the econometric issues associated with predictive regressions when using time-series data to a large extent also carry over to the panel case. The results are illustrated with an application to predictability in international stock indices.     

International harmony measures of accounting policy: comparative statistical properties

Van der Tas's (1988) I index and the between-country C index introduced by Archer et al. (1995) are competing measures of international harmony. We present comparative statistical properties of these indices, via a simulation study covering three accounting methods in 10 countries, with uniform, bimodal and unimodal distributions of companies across accounting methods. The indices are also adjusted for non-disclosures using techniques developed by Archer and McLeay (1995) and Archer et al. (1995). The I index and the between-country C index are mathematically equivalent in the two-country case even in the presence of non-disclosures. As more countries are compared, the two indices diverge. The means and standard deviations of the I index, with a correction proposed by Archer and McLeay (1995), decrease and there is little skewness or kurtosis. In contrast, as more countries are compared, the between-country C index exhibits more stability in means, lower standard deviations, higher skewness and kurtosis. The between-country C index may be superior to the corrected I index because (i) between-country C index means approximate their ‘expected values’ (where all observations equal expected values) more closely than do corrected I index means: and (ii) between-country C index means are more stable than corrected I index means where the data come from stable distributions.
