An IFRS-based taxonomy of financial ratios

Purpose - This study aims to identify a taxonomy of financial ratios derived from financial statements prepared using International Financial Reporting Standards (IFRS). The work first empirically establishes and then statistically validates the taxonomy of financial attributes captured in financial ratios. In 2005, the European Commission required that publicly traded companies in the European Union use IFRS as the basis for financial reporting. In the same year, Australia adopted IFRS as a basis for financial reporting. Since then, 120 countries and reporting jurisdictions have adopted IFRS as the basis for financial reporting. Given that IFRS predominate in the financial reporting world, it seems essential to establish and validate IFRS-based ratio attributes. Only then can reliance upon and comparability of these ratios be warranted (Altman and Eisenbeis, 1978). Using principle component analysis, the authors empirically identify nine stable attributes (factors) for ratios drawn from IFRS-based financial statements from 84 counties. The findings provides an empirical basis to formulate testable hypotheses regarding the predictive and descriptive utility of financial ratios draw from IFRS-based financial statements. Design/methodology/approach - The paper begins with a broad category of IFRS-based financial ratios, 50, found in practice and research, including income statement, balance sheet, cash flow, profitability and liquidity measures. Then, a sample of companies from the manufacturing sector is segmented using IFRS as a basis of financial statement reporting. Next, principal component analysis, a method of factor analysis, is applied to empirically identify factors and financial attributes captured in financial ratios used in research inquiry and financial analysis. Findings - The authors find that the financial attributes captured by IFRS-based ratios go well beyond the traditional measures of profitability, liquidity and solvency. The authors identify nine factors that are interpretable and stable over the period, 2011-2015: asset relationship, asset turnover, capital structure, expense insight, fixed asset usage, inventory turnover, liquidity, profitability margin and performance return. Interestingly, the authors did not find a separate cash flow factor. Most importantly, the results corroborate that IFRS-based ratios are consistent and comparable, despite innate country differences that have been shown to influence the application, interpretation and use of IFRS. Research limitations/implications - The efforts are limited to the manufacturing sector. The financial attributes may be different in service, distribution and retail sectors. Also, limiting the effort are the ratios selected in this study. A broader range of ratios may widen the identification of unique stable factors over time. Practical implications - The findings provide a basis for research and analysis efforts regarding the validity, comparability and stability of IFRS-based financial ratios. Most importantly, the results corroborate that IFRS-based ratios are consistent and comparable, despite innate country differences that have been shown to influence the application, interpretation and use of IFRS. The findings should be of interest to international and national financial reporting standard setters, investors and analysts. Originality/value - An empirically evidenced classification system for IFRS-based financial ratios has yet to be determined based on a financial statements across a wide breadth of countries and reporting jurisdictions. Identification of stable interpretable factors, financial attributes, has been limited. The first is that inquiry has been limited to domestic-based, such as US Generally Accepted Accounting Principles, financial ratios. The second is inquiry has been limited to IFRS-based financial ratios within a specific country.
