Variation In Conservatism Research Articles

Accounting Conservatism: A Literature Review

Accounting conservatism is one of the most important properties of financial reporting. The goal of this article is to gain a better understanding of accounting conservatism. We explicate the evolution of conservatism over its long history. Accounting conservatism is indispensable because the main parties of a firm demand conservatism to mitigate agency costs. Various methods are used to measure accounting conservatism, which include balance sheet measures, income statement measures and earnings/stock return relation measures. Empirical research into accounting conservatism has flourished over the last two decades and we focus on the cross‐sectional and time‐series variations in conservatism. We conclude that accounting conservatism is important and cannot be excluded from accounting standards.

The confounding effect of cost stickiness on conservatism estimates

Sales decreases affect earnings more than sales increases because of cost stickiness. We hypothesize that this correlated omitted variable constitutes a confounding effect in standard asymmetric timeliness models. Controlling for a piecewise linear effect of sales changes in these models decreases the measured asymmetric timeliness significantly and changes inferences about the average level of conservatism and the extent of cross-sectional variation in conservatism. Validation tests confirm that the asymmetry for sales changes is consistent with sticky costs and is distinct from conditional conservatism. Future empirical research on conditional conservatism should recognize the potential confounding effect of sticky costs.

Asymmetric Timeliness of Earnings: Conservatism or Sticky Costs?

Sales decreases affect earnings more than sales increases because of cost stickiness. We hypothesize that this correlated omitted variable constitutes a confounding effect in standard asymmetric timeliness models. Controlling for a piecewise linear effect of sales changes in these models decreases the measured asymmetric timeliness significantly and changes inferences about the average level of conservatism and the extent of cross-sectional variation in conservatism. Validation tests confirm that the asymmetry for sales changes is consistent with sticky costs and is distinct from conditional conservatism. Future empirical research on conditional conservatism should recognize the potential confounding effect of sticky costs.

Understanding discretion in conservatism: An alternative viewpoint

Various studies have investigated variation in reporting conservatism with pre-specified contractual incentives. Lawrence et al. (forthcoming), hereafter LSS, propose a model to control for “normal” or “non-discretionary” conservatism while testing for variation in conservatism with contractual forces, which they characterize as “discretionary” variation. Our objective is to further the discussion on discretion in conservatism by relying on LSS and incorporating insights from related studies to shed light on the rationales and relative importance of various controls for normal conservatism suggested by LSS. Furthermore, our perspective on discretion in conservatism is distinct from the one developed by LSS in some crucial respects, ultimately leading us to question the nature of the boundary between discretionary and non-discretionary conservatism.

Earnings restatements and differential timeliness of accounting conservatism

We examine whether Basu's (1997) differential timeliness metric and the related C-Score metric are effective in detecting predictable differences in conservatism surrounding corrections of overstated earnings. Cross-sectional and time-series analyses, employing 2132 firms making restatements during 1999–2005, suggest Basu-based metrics capture variation in conservatism. Further, we find that increases in conservatism following restatements are contingent on improvements in corporate governance. Collectively, these results provide evidence of the usefulness of the Basu-based metrics in the restatement setting.

Estimation and empirical properties of a firm-year measure of accounting conservatism

We estimate a firm-year measure of accounting conservatism, examine its empirical properties as a metric, and illustrate applications by testing new hypotheses that shed further light on the nature and effects of conservatism. The results are consistent with the measure, C_Score, capturing variation in conservatism and also predicting asymmetric earnings timeliness at horizons of up to 3 years ahead. Cross-sectional hypothesis tests suggest firms with longer investment cycles, higher idiosyncratic uncertainty and higher information asymmetry have higher accounting conservatism. Event studies suggest increased conservatism is a response to increases in information asymmetry and idiosyncratic uncertainty.

Estimating and validating a firm‐year‐specific measure of conservatism: Australian evidence

AbstractWe provide new evidence on the asymmetric timeliness with which economic gains and losses are recognized in Australian financial reporting (i.e. conservatism), as well as some of the factors associated with variation in conservatism. We first derive, and then estimate and subsequently validate, a firm‐year‐specific measure of conservatism (C_Score) in the manner suggested by Khan and Watts (2007). Our results indicate that conservatism is a pervasive feature of the Australian financial reporting environment. Conservatism is positively associated with stock return volatility, investment cycle length and prior period conservatism, and it is negatively associated with firm age, firm size and leverage. The results are an encouraging start for research into the causes and consequences of conservatism in Australian financial reporting.

Fair Value Accounting and Managerial Discretion

We analyse the extent to which managers exercise discretion under fair value accounting and the value relevance of these disclosures. Utilising a sample of firms that apply the UK fair value pension accounting standard, (FRS-17), we examine the main determinants of the assumptions managers use to arrive at pension scheme valuation. Despite little variation in the underlying economic inputs, differences in stated assumptions across companies, auditors and actuaries are significant. Managers display considerable variation in conservatism when implementing fair value accounting and this variation is related to scheme-specific characteristics, such as asset allocation and pension solvency. Although the disclosed amounts are found to be value relevant, the observed inconsistency in reporting across firms brings into question the efficacy of fair value accounting for assessing corporate risk.

A Proposal For Research On Conservatism

In this paper I propose explanations for conservatism in accounting and empirical tests of those explanations. Conservatism is defined as the degree to which profits are anticipated. The concept is hypothesized to have evolved from accounting's contracting role and to have been reinforced and influenced by regulation and increased legal liability. Avoidance of inappropriate distributions to claim holders appears to have been an important contracting reason for conservatism. Testable predictions for cross- sectional variation in conservatism are generated. Empirical tests for discriminating between contracting and regulatory influences are also proposed.
