A note on accounting conservatism in residual income and abnormal earnings growth equity valuation

The impact of conservative accounting on residual income (RI) and abnormal earnings growth (AEG) valuation models is investigated in this note. Limiting the analyses to information dynamics constrained models (the core models in Ohlson, 1995; Ohlson & Juettner-Nauroth, 2005), we find that both models can handle accounting conservatism if the persistence factors of residual income or abnormal earnings growth fulfil certain conditions. In a comparison of permissible time-series specifications, the AEG model can potentially handle more conservatively biased earnings in the first forecast period than the RI model. However, this requires that the growth of the conservative bias in the second forecast period is not too large. In a 0-NPV competitive equilibrium with a constant steady state growth, both models work equally well. Further elaborations indicate that, in the presence of accounting conservatism a reasonable value of the persistence factor of residual income in the RI model should be in the interval between 1.0 and R (where R = 1 + discount rate), whereas the persistence factor of abnormal earnings growth in the AEG model should be close to 1.0. This implies that the persistence factor in the RI model appears to have been understated while the persistence factor in the AEG model appears to have been overstated in previous empirical research.     

Valuation Weights,Linear Dynamics and Accounting Conservatism: An Empirical Analysis

Residual income models provide an important theoretical link between equity valuation and financial statement variables. While various researchers have developed models of how accounting policy impacts on the structure of these models, empirical support for these models is at best weak and frequently contradictory. In this paper, we develop an analytical model, which identifies the dependency between valuation weights in residual income models and the associated structure of earnings information dynamics and accounting conservatism. In contrast to many earlier studies, we find strong evidence of conservatism in our reformulation of the linear dynamics. We proceed to test our predictions of the dependency of the weights on two measures of conservatism, the conventional measure of price‐to‐book ratio and the recent measure of a C‐Score index developed by Khan and Watts (2009) and find that the empirical results accord well with our theoretical predictions in the case of the former but not the latter measure.     

Earnings Components,Accounting Bias and Equity Valuation

In this paper we address three issues in accounting-based equity valuation: (i) How are valuation parameters related to earnings persistence and accounting conservatism when earnings components aggregate, or “add up”, in valuation? (ii) What does aggregation of earnings components in valuation imply for abnormal earnings dynamics? and (iii) When is an earnings component “irrelevant” and “core”?earnings the relevant construct for valuation? Assuming linear valuation, no-arbitrage, dividend irrelevance and clean surplus accounting, we show that when earnings components aggregate, valuation expressions and abnormal earnings dynamics are generalizations of the Ohlson (1995) model, incorporating simple adjustments for accounting conservatism. When “core” earnings are the relevant earnings construct, valuation expressions closely resemble the aggregation case, but core (abnormal) earnings replaces clean surplus (abnormal) earnings. We demonstrate that an earnings component can be irrelevant in valuation even when it is predictable.     

Conditional conservatism and the limits to earnings management

We examine the impact of conditional conservatism on earnings management. Our findings support the view that conditional conservatism reduces accruals-based earnings management but also triggers a trade-off between accruals and real earnings management. In our main tests we use the passage of SFAS 121 as a plausibly exogenous regulatory change that increased the level of conditional conservatism but did not materially affect earnings management. We find that, after the regulation, treated firms reduce accruals-based earnings management and increase real earnings management, and are less likely to be marginal or habitual beaters of earnings benchmarks. Given the crucial role of earnings for firm valuation and analysis, and that conditionally conservative accounting choices are observable, our results should be of wide interest for investment professionals.     

Accounting Earnings Processes,Inter-temporal Incentives and Their Implications for Valuation

Accounting measures such as levels and changes in residual earnings are widely used for performance evaluation and executive compensation (Healy, 1985). Quite often, these compensation contracts are of the linear form. In a multiperiod agency setting with hidden actions, where the agent's effort influences the random evolution of a general model of residual earnings, we show that linear compensation contracts based on weighted sum of the levels and changes of residual earnings are indeed optimal. We characterize the contract explicitly and show that the weights are determined by the earnings persistence parameter. Residual earnings are known to be important for valuation too (Ohlson, 1995; Easton and Harris, 1991). In our setting, we demonstrate that residual earnings are also sufficient for valuation. This implies that residual earnings can be used to align incentive goals with valuation objectives. In essence, our paper provides the theoretical underpinnings for linear contracts based on residual earnings and their implications for valuation.     

Earnings quality and firm valuation: international evidence*

This study uses a sample of over 7000 firms in 38 countries to investigate the relation between firm valuation and earnings quality. We find a positive and significant relation between firm valuation and an aggregate earnings quality measure based on seven earnings attributes (accruals quality, persistence, predictability, smoothness, value relevance, timeliness, and conservatism). This relation is particularly strong for firms with greater investment opportunities and more need for external finance, and for firms in low investor protection countries. Thus, firms are able to compensate for a weak legal environment by adopting higher earnings quality standards, particularly when they need to gain access to global capital markets. Overall, our findings suggest that firms with higher earnings quality are valued more highly in stock markets, supporting the idea that investors require a premium for the information risk associated with lower‐quality earnings.     

An empirical assessment of the Feltham-Ohlson models considering the sign of abnormal earnings

This paper provides an empirical assessment of the Feltham-Ohlson models, distinguishing between firms with positive and negative abnormal earnings. Abnormal earnings persistence and conservatism parameters differ for these two groups; this implies different earnings prediction models and valuation functions for both profit-making and loss-making firms. The analysis refers to the period 1991-1999 and uses a sample of Spanish firms quoted on the Madrid S.E. The results suggest that our contextual approach is more useful than the non-contextual one to predict future abnormal earnings and explain current prices. Although the Ohlson (1995) model is accurate in forecasting future abnormal earnings and stock prices, the results improve when firms with negative abnormal earnings are valued using a temporary model and firms with positive abnormal earnings using a more permanent one. The Feltham and Ohlson (1995) model generates the lowest forecast errors in the prediction of positive abnormal earnings, but it produces the least accurate results in forecasting prices.     

An International Analysis of Historical and Forecast Earnings in Accounting-Based Valuation Models

Abstract:  In this paper we examine whether the valuation properties of historical accounting amounts, namely earnings and equity book value, differ from those of forecasted earnings for firms in 17 developed countries classified into six accounting regimes. We compare the performance of a historical model and a residual-income forecast model for explaining security prices. The historical model uses the book value of equities and actual historical earnings and the forecast model uses the book value of equities and analysts' forecasts of earnings in the residual income for estimating the intrinsic value of the firm. The results suggest that book values, historical earnings or forecasted earnings are value relevant in most regimes and countries examined. The forecast model offers significantly greater explanatory power for security prices than the historical model in the Anglo-Saxon and North American countries, Japan, Germany, and three Nordic countries. The explanatory power of the historical model is similar to that of the forecast model in the Latin countries, two Nordic countries, and Switzerland. We find that the forecast model performs similarly to the historical model where financial analysts' forecasts are noisy and analysts are less active. Further results indicate that the forecasted earnings are more value-relevant than the historical earnings in countries with stronger investor protection laws, less conservative GAAP, greater income conservatism, and more transparent accounting systems.     

Consumption-based equity valuation

Using a CCAPM-based risk-adjustment model, we perform yearly valuations of a large sample of stocks listed on NYSE, AMEX, and NASDAQ over a 30-year period. The model differs from standard valuation models in the sense that it adjusts forecasted residual income for risk in the numerator rather than through a risk-adjusted cost of equity in the denominator. The risk adjustments are derived based on assumptions about the time-series properties of residual income returns and aggregate consumption rather than on historical stock returns. We compare the performance of the model with several implementations of standard valuation models, both in terms of median absolute valuation errors (MAVE) and in terms of excess returns on simple investment strategies based on the differences between model and market prices. The CCAPM-based valuation model yields a significantly lower MAVE than the best performing standard valuation model. Both types of models can identify investment strategies with subsequent excess returns. The CCAPM-based valuation model yields time-series of realized hedge returns with more and higher positive returns and fewer and less negative returns compared with the time-series of realized hedge returns based on the best performing standard valuation model for holding periods from 1 to 5 years. In a statistical test of 1-year-ahead excess return predictability based on the models’ implied pricing errors, the CCAPM-based valuation model is selected as the better model. Using the standard series of aggregate consumption and the nominal price index, a reasonable level of relative risk aversion, and calibrated growth rates in the continuing value at each valuation date, the CCAPM-based valuation model produces small risk adjustments to forecasted residual income and low continuing values. Compared with standard valuation models, it relies less on estimated parameters and speculative elements when aggregating residual earnings forecasts into a valuation.     

Unexpected Accruals and Conditional Accounting Conservatism

Abstract:  This paper examines the impact of management discretion over accruals on conditional accounting conservatism, defined as the tendency of accountants to recognize bad news on a timelier basis than good news. Prior research suggests that conditional accounting conservatism reflected in earnings is mainly due to the accrual component of earnings, not the cash flow component of earnings. After decomposing total accruals into expected and unexpected accruals, I find that (1) conditional accounting conservatism reflected in accruals is mainly due to unexpected accruals; (2) the negative association between unconditional and conditional accounting conservatism is mainly attributable to unexpected accruals; and (3) firms with higher leverage exhibit conditionally more conservative accounting primarily through unexpected accruals. These results are robust to accrual models that take into account the systematic association between accruals and cash flows and their non-linearity and to the asymmetric persistence of earnings changes specification of conditional accounting conservatism. Taken together, these results suggest that managers exercise their discretion over accruals to expedite the recognition of bad news rather than good news.     

Discussion of “Using earnings forecasts to simultaneously estimate firm-specific cost of equity and long-term growth”

Accounting-based valuation models allow us to develop rigorous estimates of either value or the expected rate of return on equity capital (i.e., ERR) without making steady-state forecasts that rely on ad hoc assumptions about dividend policy. Hence, these models have great potential. Their ultimate usefulness, however, depends on the extent to which users of them make assumptions about future residual income that are consistent with the underlying accounting. Nekrasov and Ogneva contribute by developing a methodology that allows us to integrate information about accounting attributes such as conservatism into our estimates of the growth rate in residual income. Hence, their methodology can be used to improve our understanding of the role that conservatism plays in determining growth. This, in turn, improves our ability to estimate key parameters such as value and the expected rate of return on equity capital.     

Searching for value relevance of book value and earnings: a case of premium versus discount firms

We examine the premium/discount firm characteristic that fundamentally affects the value relevance of two key accounting line items, earnings and book values. We argue that from the perspective of both the residual income and option-style valuation models, the relative valuation roles of earnings and book values differ fundamentally between firms that trade at a premium vis-à-vis discount to book value. We find that book values play a significantly more important role in equity valuation than earnings when firms trade at a discount. We also find that other known influential conditions, such as the sign of earnings (Collins et al. in Acc Rev 74(1):29–61, 1999) or the relative levels of earnings and book value (Burgstahler and Dichev in Acc Rev 72(2):187–215, 1997), become inconsequential when the premium/discount condition of the firm is controlled for. The discovered relationships between the relative valuation roles of book values and earnings and the discount/premium characteristics of the firm are robust to the effect of time, information environment and the industry of the firm.     

The effect of differential accounting conservatism on the “over-valuation” of high-tech firms relative to low-tech firms

This paper examines systematic differences in the level of accounting conservatism between high-tech and low-tech firms. Relying on the recent development in theoretical models and empirical measures of conservatism, we investigate conservative accounting practices and earnings management behavior in high-tech and low-tech firms. The results based on comparisons of cumulative nonoperating accruals, regression coefficients from the income timeliness models in Basu (1997), the distribution of earnings, and discretionary accruals between the two groups are consistent with a higher level of accounting conservatism in high-tech firms vis-à-vis low-tech firms. Additional analyses show that the effect of conservatism cannot be used as a defense for the over-valuation of high-tech firms.     

Dividend Irrelevance and Accounting Models of Value

In accounting models of value, dividends typically appear to have a strong positive relationship with value despite theoretical reasons to expect dividend displacement. We show that this result is driven by the relationship between dividends and both core earnings and other information derived from the valuation error in the prior year. Where core earnings can be effectively modelled in a specification including other information, dividend displacement is no longer rejected. Under these circumstances dividends exhibit weak incremental predictive power for earnings and earnings expectations and hence have little impact on value. We show that valuation models are sensitive to model specification and should be used with caution when testing the value impact of firm characteristics or accounting numbers.     

Equity Valuation Using Multiples

We examine the valuation performance of a comprehensive list of value drivers and find that multiples derived from forward earnings explain stock prices remarkably well: pricing errors are within 15 percent of stock prices for about half our sample. In terms of relative performance, the following general rankings are observed consistently each year: forward earnings measures are followed by historical earnings measures, cash flow measures and book value of equity are tied for third, and sales performs the worst. Curiously, performance declines when we consider more complex measures of intrinsic value based on short-cut residual income models. Contrary to the popular view that different industries have different "best" multiples, these overall rankings are observed consistently for almost all industries examined. Since we require analysts' earnings and growth forecasts and positive values for all measures, our results may not be representative of the many firm-years excluded from our sample.     

Market implied future earnings and analysts’ forecasts

This study provides evidence on market implied future earnings based on the residual income valuation (RIV) framework and compares these earnings with analyst earnings forecasts for accuracy (absolute forecast error) and bias (signed forecast error). Prior research shows that current stock price reflects future earnings and that analyst forecasts are biased. Thus, how price-based imputed forecasts compare with analyst forecasts is interesting. Using different cost of capital estimates, we use the price-earnings relation and impute firms’ future annual earnings from three residual income (RI) models for up to 5 years. Relative to I/B/E/S analyst forecasts, imputed forecasts from the RI models are less or no more biased when cost of capital is low (equal to a risk-free rate or slightly higher). Analysts slightly outperform these RI models in terms of accuracy for immediate future (1 or 2) years in the forecast horizon but the opposite is true for more distant future years when cost of capital is low. A regression analysis shows that, in explaining future earnings changes, analyst forecasts relative to imputed forecasts do not impound a significant amount of earnings information embedded in current price. In additional tests, we impute future long-term earnings growth rates and find that they are more accurate and less biased than I/B/E/S analyst long-term earnings growth forecasts. Together, the results suggest that the RIV framework can be used to impute a firm’s future earnings that are high in accuracy and low in bias, especially for distant future years.     

Return predictability and shareholders’ real options

This study re-interprets the properties of the residual income model by highlighting the shareholders’ abandonment (liquidation or adaptation) option. We estimate the value of this real option as an explicit component of abnormal earnings in the residual income model and test the improvement in valuation after incorporating it into the model. Relative to the traditional specification of the residual income model, this real options model has a stronger predictive power for future abnormal stock returns. We also find that the superior return predictability of the real options model is pronounced in the set of firms with a high probability of exercising liquidation options (for example, those with low profitability, low growth opportunities, high underlying asset volatility, and low intangible assets), which is consistent with the importance of shareholders’ abandonment option in equity valuation. The results are robust to extensive sensitivity checks.     

Valuation of Family Firms: The Limitations of Accounting Information

This conceptual paper explores the extent to which reported accounting information captures unique family firm decision‐making and intangible asset factors that impact financial value. We review the family firm valuation‐relevant literature and identify that this body of research is predicated on the assumption that accounting information reflects the underlying reality of family firms. This research, however, fails to recognise that current accounting technology does not fully recognise the family firm factors in the book value of the firm or the implications for long‐run persistence of earnings. Thus, valuation models underpinning the extant empirical research, which are predicated on reported accounting information, may not fully reflect the intrinsic value of family firms. We present propositions on the interaction between accounting information, family factors and valuation as a road map for future empirical research with a discussion of appropriate methodologies.     

Discussion of “On Accounting-Based Valuation Formulae” and “Expected EPS and EPS Growthas Determinants of Value”

This discussion evaluates the abnormal earnings growth valuation (AEG) Model of Ohlson and Juettner-Nauroth and, in similar vein to the Ohlson review paper at this conference, compares the Model to the residual income valuation (RIV) Model that has been the centerpiece of accounting-based valuation in recent years. The discussion begins with a statement of what one looks for in a practical valuation model. The innovations of the AEG Model, well stated by Ohlson, are acknowledged. A comparison of the advantages and disadvantages of the alternative approaches provides some qualification, however, and draws out the utility of a residual income valuation approach.This revised version was published online in August 2005 with a corrected cover date.     

Creating a Bigger Bath Using the Deferred Tax Valuation Allowance

Abstract:  The provisions of SFAS No. 109 allow US companies to make an earnings big bath even bigger through the establishment of a deferred tax valuation allowance. At the time a firm recognizes a non-cash charge, it also recognizes a deferred tax asset to represent the future tax benefits of the charge. Recognition of the deferred tax asset partially mitigates the negative earnings impact of the special charge. However, if the firm does not expect to have sufficient future taxable income to utilize the future tax benefits of the charge, SFAS No. 109 requires the firm to establish a deferred tax valuation allowance, effectively eliminating the recognized deferred tax asset. Thus, the establishment of the valuation allowance amplifies the negative earnings impact of the non-cash charge. We use a valuation allowance prediction model to identify firms that create a larger-than-expected valuation allowance; these firms may be creating a large valuation allowance as a reserve to be used to manage earnings in a subsequent period. We find that the vast majority of these larger-than-expected valuation allowances apparently reflect informed management pessimism about the future in that these firms actually do have poorer operating performance in subsequent periods. We do not find any evidence that subsequent reversals of valuation allowances are used to turn a loss into a profit. However, we do find a very small number of firms that appear to have used a valuation allowance reversal to meet or beat the mean analyst forecast.
