The Impact of Financial Reporting Regulation on the Market Valuation of Reported Environmental Liabilities: Preliminary Evidence from US and Canadian Public Companies

This study investigates the economic consequences of four financial reporting regulations relating to environmental liability reporting in samples of 170 US and 156 Canadian public companies during the period 1984 to 1997. The study's purpose is to investigate the factors that make financial reporting regulation effective in enhancing the relevance and reliability of accounting information. Prior research provides the theory that financial reporting regulations impose costs on managers and create incentives for them to report accounting information that is relevant and unbiased. This study assesses these regulations' enforceability, which is viewed as arising from the regulator's power to enforce its regulations by sanctions or penalties. It tests whether the relation between market valuation and reported environmental liability accruals changes when the new regulations are enacted, and whether regulation with high enforceability has a more significant impact than regulation with low enforceability. This study uses a residual‐income valuation model to measure the valuation coefficient, or multiplier, on reported environmental liability accruals. Changes in this coefficient are used as indicators of changes in the market's assessment of the value relevance and bias of the reported accounting information. This study provides preliminary evidence indicating that financial reporting regulations issued by the securities market regulator and the accounting profession are associated with changes in the relation between market value and reported environmental liabilities in some cases, and suggests avenues for further international accounting research on the factors involved in financial reporting regulation's impact.
