Soft Computing Techniques for Querying XBRL Data

Availability of business data is an important aspect of effective financial activities. An easy access to financial information has immense influence on actions and decisions regarding investing, trade and operations of companies and firms. The proposed standard – eXtensible Business Reporting Language (XBRL) – provides a means to create a uniform framework for representing corporate and financial information. XBRL defines an easily interpretable, machine-readable and XML-based data format. Its flexibility allows for representing business data using different languages, as well as following different regulation standards. One of important benefits of XBRL is application of XML-based tools and systems that enable easy preparation, processing and validation of corporate data. It is also possible to use XML-based storage and query systems. In this paper we propose and describe a concept of soft queries. They provide the users with a human-friendly interface for interacting with XBRL data. These queries are equipped with linguistic terms (such as large, medium, small) and linguistic qualifiers (all, mostly). Such queries are able to provide the users with results similar to the results obtained when they analyse data themselves. Linguistic terms and qualifiers are represented as fuzzy sets. Fuzzy-based operations and aggregation operators allow for mimicking a human-like processing of data. The proposed approach is illustrated with queries executed on an XBRL document.

The Israeli XBRL Adoption Experience

eXtensible Business Reporting Language (XBRL) is a language for the electronic communication of business and financial data which is revolutionizing business reporting around the world. It is a tool to bridge potential language barriers and unify financial reporting. This has appeal to foreign investors, among others, who can rely on information in XBRL‐tagged financial reports to make investment decisions without having to translate financial statements from local language. In 2008, Israel required most public companies to adopt International Financial Reporting Standards (IFRS) for financial reporting and to use XBRL‐tagged reporting format, as part of an aggressive effort to make its capital markets more transparent and attractive for foreign investors. In this paper, we study all Israeli public companies and analyze the accuracy and reliability of their XBRL‐tagged financial statements that are available on MAGNA, the Israel Securities Authority's electronic system. We describe the process by which the XBRL‐based data were collected and reported. We document, categorize, and analyze deficiencies in the XBRL‐tagged filings, and inconsistencies between them and the Hebrew‐based annual reports. We observe pervasive data entry errors resulting in inaccurate XBRL‐generated financial reports, which went undetected for over one year. Further, first year XBRL reporting (in conjunction with IFRS adoption) did not increase foreign investment in the Israeli capital markets. This analysis allows us to better understand the benefits and challenges of the adoption of XBRL.     

Stakeholder engagement in internet financial reporting: The diffusion of XBRL in the UK

Internet financial reporting is now widespread with most medium and large companies in the developed world providing a wide variety of financial data online. However, much of this information mirrors the paper versions of financial reports, often with little attempt to enhance the decision usability of the data, providing a so called ‘first generation’ of online reporting (ICAEW, 2004). eXtensible Business Reporting Language (XBRL) has been designed to provide a ‘second generation’ of online reporting, specifically to enhance the usability of the data. Documents rendered in XBRL are digitally-enabled so that it is easier for stakeholders to extract information directly into spreadsheets, or any other XBRL-enabled analysis software, without the need to re-key data thus providing significant improvements in information flows and enhancing inter-company comparability.XBRL consortia have spent more than 15 years promulgating the use of this technology within the business and government communities. However, despite their efforts XBRL has not become widely diffused, there is little stakeholder engagement and very few organisations have voluntarily adopted XBRL in practice.The results of a questionnaire survey in the UK indicate that awareness of XBRL, and second generation reporting more generally, resides in key champions but there is little diffusion outside this narrow set of stakeholders. Regulatory engagement seems to be the only impetus for diffusion and better channels of communication within stakeholder networks, such as between regulators, preparers, users and the XBRL community are needed. This paper suggests that currently the supply-push for XBRL is failing to produce effective use of this technology in the UK. Greater regulatory commitment is now needed to create an impetus for XBRL such as creating tools and making publicly available, accessible, repositories of XBRL data. Unless this happens, diffusion will not occur, and the demand-pull which is now needed will vanish and XBRL will fade and die.     

XBRL and open data for global financial ecosystems: A linked data approach

Information professionals performing business activity related investigative analysis must routinely associate data from a diverse range of Web based general-interest business and financial information sources. XBRL has become an integral part of the financial data landscape. At the same time, Open Data initiatives have contributed relevant financial, economic, and business data to the pool of publicly available information on the Web but the use of XBRL in combination with Open Data remains at an early state of realisation. In this paper we argue that Linked Data technology, created for Web scale information integration, can accommodate XBRL data and make it easier to combine it with open datasets. This can provide the foundations for a global data ecosystem of interlinked and interoperable financial and business information with the potential to leverage XBRL beyond its current regulatory and disclosure role. We outline the uses of Linked Data technologies to facilitate XBRL consumption in conjunction with non-XBRL Open Data, report on current activities and highlight remaining challenges in terms of information consolidation faced by both XBRL and Web technologies.     

XBRL for Financial Reporting: Evidence on Italian GAAP versus IFRS

The systematic adoption of the eXtensible Business Reporting Language (XBRL) for financial reporting represents a great challenge. Worldwide, a large number of regulators are making an effort to promote the adoption of this standard to simplify and enhance the communication of financial information. This requires the definition of well‐structured taxonomies that can standardize and accommodate the content of financial reports prepared by firms. This study aims to analyze the regulator‐led adoption of XBRL for financial reporting. It examines the XBRL taxonomies used by Italian firms to reflect their financial reporting under rule‐based Italian GAAP and principles‐based International Financial Reporting Standards (IFRS). We compare the alignment of the Italian GAAP taxonomy and the IFRS taxonomy with Italian companies' financial statements and find two different levels of fit. The results offer useful insights for regulators and policy makers in prescribing or establishing appropriate taxonomies. We illustrate the potential impacts of the different taxonomies on the quality of financial reporting in terms of comparability and potential loss of information.     

CAP Forum on E‐Business: Assurance Reporting for XML‐Based Information Services: XARL (Extensible Assurance Reporting Language)*

Extensible business reporting language (XBRL) is an XML‐based method for financial reporting. XBRL was developed to provide users with an efficient and effective means of preparing and exchanging financial information over the Internet. However, like other unprotected data coded in XML, XBRL (document) files (henceforth “documents") are vulnerable to threats against their integrity. Anyone can easily create and manipulate an XBRL document without authorization. In addition, business and financial information in XBRL can be misinterpreted, or used without the organization's consent or knowledge. Extensible assurance reporting language (XARL) was developed by Boritz and No (2003) to enable assurance providers to report on the integrity of XBRL documents distributed over the Internet. Providing assurance on XBRL documents using XARL could help users and companies reduce the uncertainty about the integrity of those documents and provide users with trustworthy information that they could place warranted reliance upon. A limitation of the initial conception of XARL was its tight linkage with the XBRL document and the comparatively primitive approach to codifying the XARL taxonomy. In this paper, we have reconceptualized the idea of XARL as a stand‐alone service for providing assurance on potentially any XML‐based information being shared over the Internet. While our illustrative application in this paper continues to be XBRL‐coded financial information, the code that underlies this version of XARL is a significant revision of our earlier implementation of XARL, is compatible with the latest version of XBRL, and moves XARL into the Web services arena.     

Application of the Reporting Entity Concept in Australia

For decades, the reporting entity concept has been the foundation of differential reporting in Australia. Those entities classified as ‘reporting entities’ are, prima facie, required to produce full GAAP‐based financial reports while other (non‐reporting) entities are generally able to produce less complex and shorter ‘special purpose’ financial reports. In recent years, the application of the concept, as originally set out in the Statement of Accounting Concepts (SAC) 1 Definition of the Reporting Entity, has been criticized on several grounds—particularly, that it does not yield the reporting outcomes originally intended by regulators. Our analysis of 1,546 companies lodging financial statements with the corporate regulator in Australia (ASIC) shows the principles‐based criteria in SAC 1, designed to indicate the existence of a reporting entity, do not systematically explain its application by entities. Our findings are relevant for policy makers, researchers, and regulators concerned with how these choices might be more effectively regulated in future and whether this is best done through principles‐based or rules‐based approaches.     

Introducing XBRL through a financial statement analysis project

In this project, we introduce business and accounting students to the application of eXtensible Business Reporting Language (XBRL) through the use of interactive data. Students study the basic concepts and potential benefits of interactive data and XBRL. Students learn to extract the financial reports of two companies in the same industry. Then, using traditional financial analysis techniques (ratio analysis) students can compare the performance of these companies. Thus, the project accomplishes two important objectives: it introduces students to the benefits and features of XBRL-tagged financial reporting and interactive data, and it shows how this medium can be used to facilitate the analysis of financial statements. The project uses free, publicly available interactive data tools to accomplish these objectives.This project is appropriate for any level of financial accounting course in which students use public company financial statements to generate financial ratios and conduct analysis on them. We aim the project at MBA-type introductory accounting courses. In addition, we show how it can easily be expanded to be applied to higher level financial statement analysis courses, both at the undergraduate and graduate levels. The project provides some background into how XBRL-tagged financial reporting is generated, while the main focus is on application of interactive data and not the technology itself. Since XBRL is now mandated by the US Securities and Exchange Commission (SEC) for most reporting entities, it is critical for today’s business students to be familiar with this method of communicating financial information.     

CAP Forum on E‐Business: Compromise or Customize: XBRL's Paradoxical Power

Business reports are changing in response to regulatory and market demands. Requests by regulators for electronic filings of financial statements and tax forms are increasing and such filings are rapidly becoming mandatory in many countries. In response, extensible business reporting language (XBRL) is a market‐driven, collaborative effort to make electronic filings more useful to, and to reduce the burden on, both publishers and consumers of business reports. XBRL does much more than simply list data items that can be submitted in an electronic filing. XBRL is a complete set of tools for regulators or groups to fully communicate the meanings of and interrelationships among the business reporting concepts. In addition, core sets of concepts from regulators or groups can be extended, expanded, or otherwise modified for more specific communication by jurisdictions, industries, or individual corporations. This unique customization capability lets companies better present their electronic filings as parallels to their paper filings. A “customizable standard” offers new opportunities and new challenges. This paper discusses XBRL's paradoxical power ‐ the trade‐offs between customizing to better parallel existing paper reports and compromising to more closely match the standards, and the research needed for the transition from freeform to customized reports.     

The Application of Corporate Governance Indicators With XBRL Technology to Financial Crisis Prediction

ABSTRACT

The widespread adoption of eXtensible Business Reporting Language (XBRL) suggests that intelligent software agents can now use financial information disseminated on the Web with high accuracy. Financial data have been widely used by researchers to predict financial crises; however, few studies have considered corporate governance indicators in building prediction models. This article presents a financial crisis prediction model that involves using a genetic algorithm for determining the optimal feature set and support vector machines (SVMs) to be used with XBRL. The experimental results show that the proposed model outperforms models based on only one type of information, either financial or corporate governance. Compared with conventional statistical methods, the proposed SVM model forecasts financial crises more accurately.     

Information processing costs and corporate tax avoidance: Evidence from the SEC’s XBRL mandate

The IRS uses information contained in financial statements as well as tax returns to detect tax avoidance behavior. We examine the impact on corporate tax avoidance behavior of reductions in the IRS’s information processing costs resulting from the mandatory adoption of XBRL for financial reporting. Motivated by the recent debate in the U.S. Congress over the cost-benefit of mandatory XBRL reporting for small firms, we pay particular attention to small firms, which inherently have relatively high information frictions. We find that the adoption of XBRL for financial reporting results in a significant decrease in tax avoidance. We further find that the negative relation between XBRL reporting and tax avoidance is less prominent for firms subject to more intense IRS monitoring in the pre-XBRL-reporting period. Overall, our results suggest that XBRL reporting reduces the cost of IRS monitoring in terms of information processing, which dampens managerial incentives to engage in tax avoidance behavior.     

Crises,Financial Leadership,and the Six Stretches for Financial Education

The former dean of the University of Virginia's Darden School explores how business schools must adapt to prepare future business leaders to assume the leadership responsibilities necessary to respond effectively to financial crises. The article begins with a statement by Milton Friedman and Anna Schwarz in their Monetary History of the United States about the failure of U.S. policy makers to prevent the collapse of the U.S. banking system during the Great Depression. Then turning to the crisis of 2008, the author draws on recent accounts of the leadership—both effective and ineffective—provided by policymakers to support Friedman and Schwartz's contention that the success of countries in responding to crises “depends on the presence of one or more outstanding individuals willing to assume responsibility and leadership.” After citing Nassim Taleb's characterization of the financial system as inherently “fragile,” the article offers a number of insights about the kind of leadership that is likely to prove effective in protecting such systems. Using the responses of policymakers like Bernanke, Paulson, and Geithner as examples, the author observes that successful leaders rank priorities and set direction, mobilize collective action, choose whether and how to use the “panoply of tools” at their disposal, and attempt to respond in a comprehensive, coordinated way to all aspects of a crisis using a flexible set of approaches and methods that he identifies as “Ad Hoc‐racy.” With such insights in mind, the author goes on to suggest that changes in current research and teaching about leadership are likely to take the form of the following six “stretches”:

Social Capital,Trust, and Corporate Performance: How CSR Helped Companies During the Financial Crisis (and Why It Can Keep Helping Them)

The authors summarize the findings of their study, published recently in the Journal of Finance, that shows that CSR investments can help companies when they perhaps need it most—that is, during sharp downturns when overall trust in companies and markets declines. Companies with high‐CSR rankings experienced stock returns that were five to seven percentage points higher than their low‐CSR counterparts during the 2008–2009 financial crisis, and even larger excess returns during the Enron crisis of 2001–2003. High‐CSR companies during the crisis also reported better operating performance, higher growth, higher employee productivity, and greater access to debt markets—while continuing to generate higher shareholder returns as late as the end of 2013. Many of these operating improvements continued well into the post‐crisis period, though at more modest levels. As the authors view their findings, the ‘social capital’ built up by corporate CSR programs complements effective financial capital management in increasing shareholder wealth mainly by limiting companies' downside risk. CSR is seen as not only reducing systematic as well as firm‐specific risk, but as also providing protection against overall ‘loss of trust.’ The social capital created by CSR programs is said to provide a kind of insurance policy that pays off when investors and the overall economy face a severe crisis of confidence.     

Financial reporting by charities: a matched case study analysis from four countries

This paper analyses financial reporting requirements applicable to charities in four jurisdictions—Australia; England; Ireland; New Zealand—using case study analysis which compares the actual financial statements of four charities operating in the same field and with similar levels of total income. The authors highlight common issues and implications in terms of the concepts underpinning not-for-profit organization (NPO) financial reporting and argue the case for harmonized international NPO accounting standards.     

Detecting Deceptive Discussions in Conference Calls

We estimate linguistic‐based classification models of deceptive discussions during quarterly earnings conference calls. Using data on subsequent financial restatements and a set of criteria to identify severity of accounting problems, we label each call as “truthful” or “deceptive.” Prediction models are then developed with the word categories that have been shown by previous psychological and linguistic research to be related to deception. We find that the out‐of‐sample performance of models based on CEO and/or CFO narratives is significantly better than a random guess by 6–16% and is at least equivalent to models based on financial and accounting variables. The language of deceptive executives exhibits more references to general knowledge, fewer nonextreme positive emotions, and fewer references to shareholder value. In addition, deceptive CEOs use significantly more extreme positive emotion and fewer anxiety words. Finally, a portfolio formed from firms with the highest deception scores from CFO narratives produces an annualized alpha of between ?4% and ?11%.     

The Nature and Rationale of a Conceptual Framework for Financial Reporting by Islamic Banks

Islamic banks have to abide by the revealed doctrines in Islam in conducting their business and financial transactions. They employ in-house religious advisers—often referred to as Shari'a Supervisory Board (SSB)—who issue a special report to inform users of financial statements whether or not the bank has adhered to the Islamic principles. Recently, a private standard-setting body—the Financial Accounting Organization for Islamic Banks and Financial Institutions (FAOIBFI)—has been set up to externally regulate the financial reporting by Islamic banks. The FAOIBFI has published two statements on the objectives and concepts of financial reporting to act as a framework in setting accounting standards for Islamic banks. This paper examines the FAOIBFI's approach for developing objectives and concepts of financial accounting and investigates its need for such a theoretical framework. It is argued that the FAOIBFI's objectives and concepts would not be useful in mandating accounting standards on issues that are affected by religious ruling. This does not necessarily mean that such a framework may not be useful in legitimating the FAOIBFI's role and in setting accounting standards for issues that are not governed by revealed moral doctrines although it will be subject to similar limitations to those found by other standard-setting bodies in utilising and applying their framework. However, it implies that the more the FAOIBFI sets accounting standards that incorporate religious ruling, the less it would tend to find its own objectives and concepts useful. The ambiguities that may arise from different interpretations of the religious rules will require resolutions primarily by reference to religious rather than accounting authority.     

Measuring systemic risk in the European banking sector: a copula CoVaR approach

We propose a new methodology based on copula functions to estimate CoVaR, the Value-at-Risk (VaR) of the financial system conditional on an institution being under financial distress. Our Copula CoVaR approach provides simple, closed-form expressions for various definitions of CoVaR for a broad range of copula families and allows the CoVaR of an institution to have time-varying exposure to its VaR. We extend this approach to estimate other ‘co-risk’ measures such as Conditional Expected Shortfall (CoES). We focus on a portfolio of large European banks and examine the existence of common market factors triggering systemic risk episodes. Further, we analyse the extent to which bank-specific characteristics such as size, leverage, and equity beta are associated with institutions' contribution to systemic risk and highlight the importance of liquidity risk at the outset of the financial crisis in summer 2007. Finally, we investigate the link between macroeconomy and systemic risk and find that changes in major macroeconomic variables can contribute significantly to systemic risk.     

The Italian economia aziendale and chambers' CoCoA

At first glance the Italian accounting tradition of Economia Aziendale and Chambers’ system of Continuously Contemporary Accounting (CoCoA) appear extreme opposites. The ex ante financial calculation of distributable income drawing on the net present values of the aggregative net assets in the former, and in the latter a system of accounting for an all‐inclusive income with the separable assets measured in terms of their current cash equivalents, appear irreconcilable, unlikely bedfellows. But the International Financial Reporting Standards present a system using separable and aggregative assets’ fair values and calculations of their net present values in assessing asset impairment. Whether Economia Aziendale and CoCoA are indeed so opposed deserves renewed examination. Anglo‐American accounting, of which expositions of CoCoA are part, is said to lack a business economics tradition of the kind said to justify Economia Aziendale. This stands in stark contrast with European traditions manifested in the Dutch Bedrijfseconomie, the German Betriebswirtschaft, and the Italian Economia Aziendale. This article seeks to understand that absence by contrasting—the Economia Aziendale framework and accounting theory developed in the Anglo‐American tradition. The primary elements of space and time coordination—the lynchpins of the pure theory of the azienda (the core of Economia Aziendale)—are generally regarded as missing in the Anglo‐American tradition. But the original construction of Economia Aziendale leads to the generalization that any attempt to determine a firm's value or to measure and analyse its performance during its lifetime would result in an unacceptable interruption of the space and time coordination, and yield unreliable results. Curiously, the analysis here exposes an unexpected complementarity of Chambers’ CoCoA and some postulates of the pure theory of Economia Aziendale. The theory that has been only partially acceptable to the Anglo‐American profession (namely its use of market [fair] values) emerges as highly compatible with the most theoretically extreme in the Italian tradition.
