Accounting Conservatism and the Relation Between Returns and Accounting Data Abstract The study adds change in cash investments and change in lagged operating assets to the regression of returns on earnings levels and earnings changes examined in Easton and Harris (1991). The model in Feltham and Ohlson (1996) suggests that a positive coefficient on change in cash investments captures conservatism associated with investments in positive net present value projects the effects of which will not flow into the accounting statements until the expected future benefits are realized. A positive coefficient on change in lagged operating assets implies accounting conservatism associated with the application of accounting rules (such as expensing rather than capitalizing R&D expenditures) to operating assets in place. Our empirical results are, in general, consistent with the predictions from Feltham and Ohlson (1996). We examine differences in conservatism across samples with different market to book ratios, we compare firms with non-negative returns with firms with negative returns, we compare firms reporting losses with firms reporting profits, and we examine firms in different industries, firms with different levels of research and development expenditure, different amounts of depreciation, different amounts of advertising expense, and firms that adopt LIFO inventory valuation compared with those that adopt an alternative to LIFO. 1 1. Introduction The study adds change in cash investments and change in lagged operating assets to the regression of returns on earnings levels and earnings changes examined in Easton and Harris (1991).1 We show that change in cash investments and change in lagged operating assets have incremental explanatory power (over earnings levels and earnings changes) for returns suggesting that accounting is conservative in the Feltham and Ohlson (1996) sense. The model in Feltham and Ohlson (1996) suggests that a positive coefficient on change in lagged operating assets implies accounting conservatism associated with the application of accounting rules (such as expensing rather than capitalizing R&D expenditures) to operating assets in place. A positive coefficient on change in cash investments captures conservatism associated with investments in positive net present value projects the effects of which will not flow into the accounting statements until the expected future benefits are realized. Our empirical results are, in general, consistent with the predictions from Feltham and Ohlson (1996) providing evidence of accounting conservatism. Feltham and Ohlson (1995, 1996) generalize and extend Ohlson (1995) by introducing the notion of accounting conservatism (defined as market value exceeding book value in the long run). With few exceptions empirical studies of the relation between returns and accounting data rely on Ohlson (1995) implicitly ignoring the effects of conservatism. Easton and Harris (1991) show that deflated (by beginning-of-period stock price) earnings levels and deflated earnings changes have significant explanatory power for annual returns. Their regression is implicitly based on Ohlson (1995) in which accounting is assumed to be unbiased (that is, the market value of equity equals the book value of equity in the long run). However, the current disparity between market value of equity and book value of equity suggests that accounting is not likely to be unbiased. Empirical tests are performed on a sample of 53,554 firm-year observations from 1988 to 2001. The mean of the year-by-year estimates of the coefficients on change in 1 We also add lagged dividends in all of our analyses as another explanatory variable for returns. The focus in Easton and Harris (1991) is on earnings changes and earnings levels although they note their model suggests that dividends should be included as an additional explanatory variable. Easton and Harris (1991) observe that inclusion of lagged dividends does not affect their inferences. 2 lagged operating assets is not significantly different from zero while the mean of the estimate of the coefficient on change in cash investments is 0.266 (t-statistic of 7.56). The significantly positive estimate of the coefficient on change in cash investments suggests that accounting is conservative, consistent with the results in Ahmed, Morton, and Schaefer (2000). We find that accounting conservatism as defined in Feltham and Ohlson (1996) is more pronounced for firms where the market value of operating assets is high relative to their book value (this is consistent with use of the ratio of the market value of common equity to the book value of common equity as a proxy for accounting conservatism in Beaver and Ryan (2000)).2 Our empirical analyses demonstrate that the magnitude of the estimates of the coefficients on change in cash investments and change in lagged operating assets increase as the price to book ratio increases. Industry-specific analysis shows evidence of varying degrees of accounting conservatism across industries. Accounting conservatism is particularly evident in the pharmaceutical industry. Following Basu (1997) who suggests that accounting will be more (less) conservative for firms with good (bad) news over the fiscal period, we seek evidence of a difference in accounting conservatism between firms with non-negative returns (good news) and firms with negative returns (bad news). Consistent with Basu (1997), the estimate of the coefficient on change in cash investments is significantly less for firms with net bad news (negative returns) than the estimate of the coefficient on change in cash investments for firms with net good news (non-negative returns). The estimate of the coefficient on change in lagged operating assets is significantly negative for firms with negative returns while it is not significantly different from zero for firms with nonnegative returns. In the Feltham and Ohlson (1995, 1996) model lagged operating assets have negative weight if there is under-depreciation of these assets. That is, for these firms where the market assessed the net change in value as negative, accounting recorded a smaller decline in value. The negative estimate of this coefficient suggests that the accruals of firms with net bad news are not sufficient to make accounting earnings fully 2 Feltham and Ohlson (1995, 1996) assume that financial assets are marked-to-market and hence conservatism arises in the accounting for operating assets. It follows that the ratio of the market value of net operating assets to the book value of net operating assets (as opposed to the ratio of the market value of common equity to the book value of common equity) may be a more appropriate indicator of conservatism. We show that results are very similar for samples formed on either of these market-to-book ratios. 3 reflect the decline of firm value in years of negative returns. Hayn (1995) focuses on the news in earnings rather than the news in returns to motivate an analysis of the returns/earnings relation for firms reporting losses compared with firms reporting profits. In order to examine the effects of losses on accounting conservatism, we partition the sample into profit and loss firms. Our empirical analyses suggest that there is no difference in accounting conservatism associated with the application of accounting rules between firms reporting losses and firms reporting profits. The estimates of the coefficients on change in cash investments are positive for both profit and loss firms consistent with the notion that cash investments are generally in positive net present value projects. Several studies have examined whether accounting is on average conservative. Even though the generally positive difference between market value and book value of equity suggests that accounting is likely to be conservative, the extant empirical studies based on Feltham and Ohlson (1995, 1996) do not provide convincing evidence. Accounting conservatism is usually examined by estimating either the Feltham and Ohlson (1995) information dynamics or the implied valuation function.3 Contrary to the general belief that accounting is conservative, empirical studies based on the information dynamics generally provide evidence that is consistent with aggressive accounting (Dechow, Hutton, and Sloan 1999; Myers 1999; Ahmed, Morton, and Schaefer 2000). The results of empirical studies of the valuation relation are mixed. Myers (1999) provides empirical evidence consistent with unbiased or aggressive accounting while Ahmed, Morton, and Schaefer (2000) report empirical results consistent with conservative accounting.4 In this paper, we seek evidence of conservatism using the valuation relation rather than the information dynamics.5 We provide empirical evidence of accounting 3 Ohlson (1995) and Feltham and Ohlson (1995, 1996) model value relevant information through a set of Markovian processes in which current information is sufficient for prediction of future value relevant information. The information dynamics refer to the sets of Markovian processes assumed in Ohlson (1995) and Feltham and Ohlson (1995, 1996). 4 Under conservative accounting, the coefficient on the book value of equity should (in a price-levels regression) be greater than one. Myers (1999) reports that the coefficient on the book value of equity is less than one (see his Table 4 and 5). Ahmed, Morton and Schaefer (2000) regress goodwill (the difference between market value and book value of equity) on residual operating earnings, lagged operating assets, and cash investments. Their significant positive coefficient on lagged operating assets is evidence of conservative accounting. 5 The information dynamics in Feltham and Ohlson (1995, 1996) and Ohlson (1995) are a means to the end 4 conservatism using the return specification rather than the levels specification: the empirical results based on the return specification are less susceptible to scale effects, omitted variables, and multicollinearity. We show that the degree of accounting conservatism varies with the ratio of market value to book value and it differs across industries, we demonstrate the different effects of accounting conservatism associated with accounting rules and accounting conservatism associated with investment in positive net present value projects, and we show some consistency between the empirical implications gleaned from the Feltham and Ohlson (1995, 1996) notion of conservatism and other notions of conservatism in the extant literature. The paper proceeds as follows. In section 2, we develop an empirical regression model that is implied by Feltham and Ohlson (1996). Section 3 describes the data and the sample selection procedure. Section 4 reports the results of the empirical analysis. We summarize these results and draw conclusions in section 5. 2. Model Our empirical regression model is based on Feltham and Ohlson (1996) rather than Ohlson (1995). In later analyses we consider the empirical implications of Feltham and Ohlson (1995). Feltham and Ohlson (1996) explicitly model the possibility of conservative accounting whereas Ohlson (1995) implicitly assumes unbiased accounting. As in Feltham and Ohlson (1996), accounting is defined as conservative (unbiased) if the value of a firm is expected to exceed (equal) the firm's book value of equity in the long run. The basic ingredients of the Feltham and Ohlson (1996) model are: (1) the cash flow dynamics: 6 of understanding the mapping from accounting data to security prices. We focus on this mapping. Of course, the mapping will be affected by the assumed dynamics. Empirical analysis of the information dynamics is, in essence, examination of the descriptive validity of a key assumption akin to testing the capital asset pricing model by determining whether multi-variate normality is descriptive of stock returns. Like the literature on the capital asset pricing model, we focus on the implications of the model rather than the assumptions. Lack of descriptive validity of the information dynamics suggests that we should only use the model as guidance for our empirical analyses. We will return to this point in the next section of the paper. 6 For the sake of simplicity, the information dynamics in our paper do not include dynamics for other information. In Feltham and Ohlson (1995, 1996), other information is modeled to represent information 5 c~rt 1 crt kcit ~1t 1 c~it 1 cit ~2t 1 (CFD) (2) the present value of cash flow relation: Vt R E t [c~t ] (PVCF) 1 and (3) the operating asset relation: oat oat 1 oxt ct oat 1 oact cit (OAR) where > 0, [0,1), [0, R), crt and cit are cash receipts and cash investments, ct ( crt - cit) is net cash flows, Vt is the market value of operating assets at date t, R is one plus the riskless rate of return (r), oat is net operating asset at time t, oxt is operating earnings, and oact is operating accruals for period t. Assumptions CFD, PVCF, and OAR are sufficient to derive the following valuation relation: Vt oat 1oxta 2 cit R( 1)oat 1 oact where [ R ]1 , 1 , 2 [ 1] (1) R , and oxta ( oxt ( R 1)oat 1 ) is R residual operating income. Invoking the Feltham and Ohlson (1995) assumption that financial assets are valued at market, equation (1) may be re-written as: pt bt 1 xta 2 cit R( 1)oat 1 oact (2) where pt is the market value of equity at time t, pt is the book value of equity at time t and xta is residual earnings for period t (that is, xt – (R-1)bt-1).7 about future revenues and/or growth opportunities, which may not be reflected in the accounting variables. We argue that the effect of the omission of other information in the return setting used in our empirical analyses will be minimal since, in this setting other information is less likely (compared with the pricelevels setting) to be highly correlated with the variables that capture the effect of accounting conservatism. Other studies have introduced other information variables in the Feltham and Ohlson (1995, 1996) setting. For example, Begley and Feltham (2002) demonstrate how to extract other information using one-year and two-year-ahead analysts’ forecasts. Liu and Ohlson (2000) show that analysts’ forecasts about one-yearahead operating earnings and operating assets can be used to infer other information. Myers (1999) uses sales backlogs as a proxy for other information. Of course, as a practical matter there are an infinite array of potential other information variables. 7 The assumption that financial assets are valued at market value is also frequently made in the finance literature (see, for example, Brealey and Myers 2002). Of course, there are many financial assets and obligations for which this assumption may not hold. Allowing for this possibility in the Feltham and Ohlson (1996) framework would require introducing an accounting depreciation rate for financial assets 6 Feltham and Ohlson (1996) examine the effect of accounting accruals on the relation between accounting numbers and firm value by focusing on the relation between operating accruals (the accounting measure of change in value of operating assets – referred to generically as depreciation) and beginning of period book value of operating assets. In the interest of parsimony, they invoke the simplifying assumption that operating accruals are a constant proportion (1- ) of beginning of period operating assets. Although this proportion (1- ) may be viewed as an accrual that has the characteristics of the declining balance depreciation method, it will also capture any change in the accounting measure of the value of operating assets. For example, research and development costs that are expensed immediately have a of zero. In general, may be viewed as the weighted average of the accounting measures of change in value. Under this simplifying assumption, Feltham and Ohlson (1996) suggest the following value relation: pt bt 1 xta 2 cit 3 oat 1 (3) where 3 R( ) . Taking first differences and rearranging yields: pt dt pt 1 (1 r1 ) xt R1xt r1dt 1 2 cit 3oat 1 (4) The coefficient on change in lagged operating assets captures the effect of accounting value added, and the coefficient on change in cash investments captures the effect of economic value added. We elaborate on this point. Recall that 3 R( ) . That is, change in lagged operating assets (oat-1) has positive weight if there is over-depreciation of these assets (that is, the accounting that differs from the economic depreciation rate (analogous to (1-) and (1-) for operating assets). Any difference between these rates would be captured via the estimate of the coefficient on an additional variable, change in lagged financial assets. Occasionally estimates of this coefficient are significantly positive when change in lagged financial assets is added to the regressions in the latter part of the paper – the estimates of the coefficients on the remaining variables are not changed significantly. Also, cash investments in financial assets may be in positive net present value projects suggesting that a positive estimate of coefficient on change in cash investments may also reflect conservatism in the accounting for these assets. These investments are, however, generally viewed as means of holding reserves for future investments in operations and are thus unlikely to be positive net present value. As a practical matter, Compustat data does not permit us to separate cash investments in operations and cash investments in financial assets. Hence, our estimate of the coefficient on change in cash investments captures positive net present value investments in both of these asset types. 7 depreciation rate (1-) is greater than the economic depreciation rate (1-)).8 In other words, if assets have been over-depreciated in the past, future earnings will be higher because there will be less depreciation to match against revenues. Since this higher earnings is due to the accounting policy (depreciation rate), the consequent positive residual income reflects only accounting value added – not economic value added. If , operating assets are recorded at market value – and thus goodwill (the present value of future residual income) associated with depreciation of beginning operating assets is zero. Recall that 2 [ 1] R . That is, current investments cit have positive R weight if they have positive NPV (that is, > 1). Note that cash investments at the end of the current period do not affect residual income of the current period (this captures the reality that new investments do not affect accounting earnings until products are sold or a service is provided). The effect of current investments is on residual income of future periods. That is, positive residual income in future periods may reflect economic value added in past periods but positive residual income in the current period does not reflect economic value added in the current period. To summarize, if accounting is conservative as in Feltham and Ohlson (1995, 1996), change in cash investments, change in lagged operating assets, and lagged dividends should be included as additional variables in the return, earnings levels, and earnings changes regression as in equation (4). The lack of consideration of accounting conservatism may affect the estimates of the coefficients on earnings levels and earnings changes because change in cash investments, change in lagged operating assets and/or lagged dividends may be correlated with these variables. Most of our analyses are based on regressions that are the empirical analogue of equation (4) with all variables scaled by beginning market value of equity: 9 ret jt 0 1 x jt p jt 1 2 x jt p jt 1 3 d jt 1 p jt 1 4 ci jt p jt 1 5 oa jt 1 p jt 1 jt , (5) The term depreciation is used in the general sense of “change in value”. Consistent with all papers that use Ohlson (1995) and/or Feltham and Ohlson (1995, 1996) we estimate the relation between the variables identified in equation (4) for a cross-section of firms. However, we note that these models are based on a single-firm economy and the implications for a multi-firm economy are not addressed. It follows that the conclusions from our empirical tests must be interpreted with this shortcoming in mind. 8 9 8 where ret jt ( p jt d jt p jt 1 ) / p jt 1 .10 The subscript j denotes an observation for firm j. The cross-sectional regressions are run separately for each year of available data. 4 captures the effect of conservatism due to future positive NPV projects, and 5 captures the effect of conservatism due to accounting rules. The coefficients on earnings levels, earnings changes, and lagged dividends are all predicted to be positive.11 3. Data Selection and Sample Description Initially, we collect all Compustat firm-year observations from fiscal years 1988 through 2001 for which we have complete data for the following items. Return ( ret t ) is obtained from CRSP by compounding monthly returns during the fiscal period. We use comprehensive income as a measure of earnings ( xt ). Comprehensive income is net income (#172) minus preferred dividends (#19) plus the change in value of marketable securities (#238) plus the change in cumulative foreign currency translation adjustment (#230). The change in comprehensive income is denoted by xt. Dividends ( d t ) are the sum of dividends to common shareholders (item #21) and net capital contributions. Net capital contributions are purchases of common and preferred stock (item#115) minus sales of common and preferred stock (item#108). Operating assets ( oat ) are book value 10 Equation (4) suggest that restrictions could be placed on the relations among the coefficients 1 , 2 and 3 . The coefficient estimates sometimes differ significantly when these restrictions are imposed suggesting that the Feltham and Ohlson (1996) model is not descriptively valid and thus our empirical model is mis-specified. It follows that conclusions regarding the significance of the estimates of the coefficients on change in cash investments and change in lagged operating assets must be made with the accompanying caveat that the results may reflect mis-specification of the model that we use to motivate their inclusion in the returns regression. 11 Unlike Easton and Harris (1991) we use returns of the fiscal period rather than returns for the twelve months ending three months after fiscal year end. This choice is motivated by the fact that the focus in our analysis is a comparison of the change in value of the assets as captured in the accounting data with the change in the value of these assets as captured by the market in the same period. Lagging returns by three months introduces the possibility that the accounting data conveys information to the market. Although this introduces concepts that go beyond the model in Feltham and Ohlson (1996), we repeated all analyses using returns lagged three months. All conclusions are qualitatively the same. Easton and Harris (1991) also employ abnormal returns as another return metric. In our empirical regression, the use of abnormal returns ( ( p jt d jt Rp jt 1 ) / p jt 1 ) rather than raw returns ( ( p jt d jt p jt 1 ) / p jt 1 ) will affect the intercept. If the regression model is well specified and we use raw returns as a return metric, the intercept ( 0 ) will be zero. If we use abnormal returns instead of raw returns, the intercept will be smaller by the estimate of the “normal return”. 9 of equity ( bt ) minus financial assets ( fat ). Book value of equity (bt) is common equity (#60) plus preferred treasury stock (#227) minus preferred dividends in arrears (#242). Financial assets (fat) are cash and short-term investments (#1) plus investments and advances-others (#32) minus debt in current liabilities (#34) minus long-term debt (#9) minus preferred stock (#130) plus preferred treasury stock (#227) minus preferred dividends in arrears (#242) minus minority interest (#38). Cash investments are obtained from the cash flow statement as the negative of cash flows from investing activities (#311). 12 The ratio of the market value of operating assets to the book value of operating assets (V/oa) is the market value of common equity minus financial assets (fat) divided by the book value of operating assets ((pt - fat)/oat). All variables except the market value of equity ( p t ), annual stock returns ( ret t ), and ratio of the market value of operating assets to the book value of operating assets (V/oa) are deflated by the beginning market value of equity ( pt 1 ). Observations with negative book value of equity or negative book value or market value of operating assets are excluded. We further delete observations in the top and bottom one percent of the distribution for any one of the following variables: annual returns, earnings levels, earnings changes, lagged dividends, change in cash investments, and change in lagged operating assets in order to mitigate the effect of extreme values. The final sample is 53,554 firm-year observations, which consist of 37,169 firmyear observations reporting profits (profit firms, hereafter) and 16,385 firm-year observations reporting losses (loss firms, hereafter) and 28,366 observations with nonnegative returns (good news firms, hereafter) and 25,188 observations with negative returns (bad news firms, hereafter). The lack of data necessary to measure cash investments (cit) restricts most of our analysis to the post-1987 period. Panel A of table 1 reports descriptive statistics for the sample of 53,554 firm-year observations from 1988 through 2001. The median market value of equity is $128.26 million. Over the 14 years, the mean and median annual raw stock returns are 12.2% and 3.2%, respectively. Median net comprehensive income and the change in net comprehensive income are 4.3% and 0.4% of the beginning market value of equity. Median lagged dividends are zero. The decomposition of book value of equity into 12 Nissim and Penman (2001) provide detailed justification and explanation of their methods for measuring the accounting related variables. We use their definitions and we use the same data sources. 10 operating assets and financial assets shows that firms have on average net financial obligations; hence operating assets are greater than book value of equity. The positive change in operating assets (median of 3.8 percent of price) implies that operating assets are on average increasing. The ratio of the market value of operating assets to the book value of operating assets is generally greater than one although, for about 18 percent of the sample, market value of operating assets is less than their book value. Panel B of table 1 reports descriptive statistics for profit and loss sub-samples. Profit firms are, on average, bigger than loss firms. The median market values of equity for profit and loss firms are $214.68 million and $43.51 million, respectively. Loss firms have, on average, higher market to book (P/B and V/oa) ratios than profit firms. This is due to both higher market value of equity for profit firms and lower book value of equity for loss firms. Panel C of table 1 reports descriptive statistics for firm-years with non-negative returns (“good” news) and for the firm-years with negative returns (“bad” news). The median market values of equity for good and bad news firm-years are $232.84 million and $66.97 million, respectively. Good news firm-years have, on average, higher market to book (P/B and V/oa) ratios than bad news firms. Table 2 reports the Pearson and Spearman correlations among key variables. The correlations between the returns and each of the independent variables are significant at, at least the 0.01 level. The correlations between change in lagged operating assets and both earnings changes and change in cash investments are high (-0.250 and –0.217, respectively) suggesting that multicollinearity may affect the stability of the estimates of the coefficients on these variables. 4. Empirical Results 4.1. Conservatism in the entire sample Table 3 summarizes the output from regression (5) for each of years 1988 to 2001. Conservatism associated with investment in positive NPV projects (economic value added) is evident in the data. However, there is no evidence of conservatism due to accounting rules (accounting value added). The estimate of the coefficient on change in cash investments is significantly 11 positive in every annual regression except year 2001. The mean of these estimates (0.266) is significantly positive at, at least, the 0.01 level (t-statistic of 7.56). This evidence is consistent with the notion in Feltham and Ohlson (1996) that conservative accounting does not reflect the effects of investments in positive net present value projects until future periods. The estimates of the coefficient on change in cash investments are significantly positive in 13 of the 14 annual regressions, providing some comfort that multicollinearity (which may lead to instability of the coefficient estimates) is not unduly affecting the analyses. The mean of the estimates of the coefficient on change in lagged operating assets is not significantly different from zero at conventional levels (t-statistic of –0.59) suggesting that conservatism associated with over-depreciation of assets in place has no incremental explanatory power for returns over earnings, earnings changes, and lagged dividends. The mean of the adjusted R2 is 11.5%. The estimates of the coefficients on earnings, earnings changes, and lagged dividends are all positive as predicted. The mean estimates of the coefficients on earnings and earnings changes are significant at the 0.01 level. However, the mean of the estimates of the coefficients on lagged dividends is not significantly different from zero. 4.2. A Comparison with Easton and Harris (1991) We now investigate the effect of the omission of change in cash investments and change in lagged operating assets from regression (5). The results of this investigation are reported in table 4. The estimate of the coefficient on earnings levels in the simple regression of returns on deflated earnings levels (model M1) is significantly positive at the 0.01 level (t-statistic of 9.25). The estimate of the coefficient on earnings changes in the simple regression of returns on deflated earnings changes (model M2) is also significantly positive at the 0.01 level (t-statistic of 15.37). This result is consistent with Easton and Harris (1991).13 Next, we regress annual stock returns on both earnings 13 Easton and Harris (1991) report the estimate of 1.02 (with t-statistic of 10.0) on earnings levels and 0.74 (with t-statistics of 0.74) on earnings changes. The sample period and the measures of returns and earnings of Easton and Harris (1991) are different from this study. Easton and Harris (1991) examined the sample period from 1968 to 1986, and their returns are measured for a year ending three months after fiscal period. 12 levels and earnings changes (model M3). The mean estimates of the coefficients on earnings levels and earnings changes are 0.655 and 0.533, respectively, with associated tstatistics of 5.35 and 7.10, respectively. Consistent with the Ohlson (1995) model, we add lagged dividends to earnings levels and earnings changes as explanatory variables for returns (model M4). The addition of lagged dividends does not materially increase the adjusted R2, and the estimate of the coefficient on lagged dividends is not significantly different from zero at the 0.05 level. Addition of change in cash investments and change in lagged operating assets increases the average adjusted R2 from 10.2% (in model M4) to 11.5% (in model M5). The estimate of the coefficient on earnings levels decreases from 0.628 to 0.593 (with a tstatistic for the difference between these coefficient estimates of -2.95) while the estimate of the coefficient on earnings changes increases from 0.545 to 0.620 (with a t-statistic for the difference between these coefficient estimates of 1.22). 4.3. The Current Market to Book Ratio as a Proxy for Conservatism Even though conservatism is defined in Feltham and Ohlson (1995, 1996) as an asymptotic relation between market value of equity and book value of equity in the long run, the current price to book ratio may be used as an indication of the degree of conservatism if it is expected to persist into the future. We note, however, that Feltham and Ohlson (1995, 1996) assume that financial assets are marked-to-market and hence conservatism arises in the accounting for operating assets. It follows that the ratio of the market value of net operating assets to the book value of net operating assets (as opposed to the ratio of the market value of common equity to the book value of common equity) may be a more appropriate indicator of conservatism. We partition the sample each year into deciles based on the ratio of the market value of net operating assets measured as the market value of equity minus the book value of financial assets (that is, pt fat ) to book value of operating assets (that is, oat ) and we examine whether the current ratio of market value of net operating assets to book This paper uses comprehensive income as a measure of earnings. 13 value of net operating assets is related to accounting conservatism as we have defined it in our regression (5). We expect that the higher the current ratio of market value of net operating assets to book value of net operating assets, the more conservative the accounting. All of the analyses in this section of the paper have been repeated using the ratio of the market value of common equity to book value of common equity with very similar results. Table 5 summarizes the output from regression (5) conducted within deciles of market value of net operating assets to book value of net operating assets. Decile 1 includes firms with the lowest ratios of market value of net operating assets to book value of net operating assets, and decile 10 includes firms with the highest ratios.14 If the current market to book ratio is a good proxy for accounting conservatism, the coefficients on the change in cash investments and change in lagged operating assets will increase as we move from decile 1 to decile 10. Table 5 reports that the median market to book (V/oa) ratio is less than one for deciles 1 and 2, implying that accounting is more likely to be aggressive.15 For deciles 3 and higher, the median market to book (V/oa) ratios are greater than one, implying that accounting is more likely to be conservative. The estimate of the coefficient on change in lagged operating assets is significantly negative for decile 1 consistent with the change in value represented by the accruals being less than the change in value reflected in returns. Accounting conservatism in the higher V/oa deciles is seen in significantly positive estimates of the coefficients on change in lagged operating assets for deciles 4 and higher. The estimates of the coefficients on change in cash investments increase monotonically from 0.033 for the decile with lowest V/oa to 1.131 for the decile with highest V/oa. To summarize, the higher estimates of the coefficients of change in lagged operating assets and change in cash investments for higher price-to-book ratio samples confirm our prediction that the current market to book ratio appears to capture conservatism as modeled in Feltham and Ohlson (1996). 14 In the discussion of the results in table 5, we will refer to the ratio of the market value of net operating assets to book value of net operating assets as the market to book ratio. 15 That is, the accounting estimate of change in value is greater than the market’s assessment of change in value for these firms. 14 4.4. Conservatism and Industry Table 7 reports medians of key variables by industry. Utilities and firms in the chemicals and transportation industries have larger market value of equity. The median annual stock returns are positive in all industries other than the mining and construction, computers, and services industries. The median net income is positive in all industries other than the pharmaceutical industry. The median price to book ratio is greater than one for all industries. The pharmaceutical industry has the highest median price to book ratio followed by the computer industry. The positive median change in cash investments for all industries suggests increasing cash investments in operations over this time period. Consistent with increasing cash investments, the median change in lagged operating assets is positive for all industries. Table 8 reports the results from regression (5) conducted at the industry level. The estimates of the coefficients on change in cash investments (consistent with investment in positive net present value projects) are significantly positive in all industries other than agriculture, mining and construction, food, chemicals, transportation, insurance and real estate, and others. The estimates of the coefficients on change in lagged operating assets are not significantly different from zero with the exception of pharmaceuticals (t-statistic of 5.41), extractive industries (t-statistic of 2.53), and durable manufactures (t-statistic of -2.65). Note that the pharmaceutical industry has the highest median V/oa (7.268). These results are consistent with those in Table 5. 4.5. Positive Returns vs. Negative Returns and Conservatism Basu (1997) observes that the explanatory power of earnings for returns differs according to whether news is on average good (that is, returns of the fiscal period are positive) or news is on average bad (negative returns). In order to examine this effect, firms are partitioned according to the sign of their fiscal period returns and regression (5) is re-estimated for the two partitions of the data. Panel A of table 9 reports that the estimate of the coefficient on earnings in the regression of returns on earnings for non-negative returns firms is not significantly different from zero (0.073) and (also consistent with Basu (1997)) panel B of table 9 15 reports that the estimate of this coefficient for firms with negative returns is significantly positive (0.418 with a t-statistic of 9.39). The estimate of the coefficient on earnings changes is significant for both good news and bad news firms. The results from regression (5) show that for firms with net good news (panel A) the estimate of the coefficient on change in lagged operating assets is not significantly different from zero at the 0.05 level. However, the estimate of the coefficient on change in lagged operating assets is significantly negative (t-statistic of –2.49) for firms with net bad news (panel B). In the Feltham and Ohlson (1996) model, lagged operating assets have negative weight if there is under-depreciation of these assets (that is, the accounting depreciation rate (1-) is less than the economic depreciation rate (1-)). That is, for these firms where the market has assessed the net change in value as negative, accounting recorded a smaller decline in value. The estimate of the coefficient on change in cash investments is significantly positive for both the non-negative and the negative returns sample suggesting that there is accounting conservatism associated with firms investing in positive net present projects. However, the estimate of the coefficient on change in cash investments for firms with net good news (0.228) is significantly greater (t-statistic of difference (un-tabulated) of 6.13) than the estimate of this coefficient for firms with net bad news (0.024). This result is consistent with the notion that firms with net good news have a greater tendency to invest in positive net present value projects. The result is also consistent with Basu’s (1997) idea that accounting is less conservative for firms with net bad news than firms with net good news. 4.6. Profit vs. Loss and Conservatism Hayn (1995) focuses on the news in earnings rather than the news in returns to motivate an analysis of the returns/earnings relation for firms reporting losses compared with firms reporting profits. In order to examine the effects of losses on accounting conservatism, we partition the sample into profit and loss firms. Consistent with Hayn (1995), Panel A of table 10 reports that the estimate of the coefficient on earnings in the simple regression of returns on earnings for profit firms is significantly positive (3.57) at, at least, the 0.001 level (t-statistic of 19.71). Panel B of 16 table 9 reports that the estimate of this coefficient for loss firms is not significantly negative (-0.025 with a t-statistic of -0.41). The estimate of the coefficient on earnings changes is significant for both profit and loss firms. The results from regression (5) show that the estimate of the coefficient on change in lagged operating assets is not significantly different from zero for both profit and loss firms (t-statistics of -0.70 and -0.83, respectively). In other words, there is no difference in accounting conservatism associated with the application of accounting rules (t-statistic of difference (un-tabulated) of 0.05) between profit and loss firms. The estimate of the coefficient on change in cash investments is significantly positive for both profit and loss firms (t-statistics of 7.19 and 6.73, respectively). The evidence suggests that cash investments for both profit and loss firms are generally in positive net present value projects. The estimate of the coefficient on change in cash investments for profit firms (0.216) is significantly less (t-statistic for difference (untabulated) of -2.63) than the estimate of this coefficient for loss firms (0.294). In other words, cash investments undertaken by loss firms have a greater tendency to have positive net present values than those undertaken by profitable firms. At first glance this may seem strange. We suggest that this reflects the nature of the firms that report losses during our sample period – it is evident from descriptive statistics reported in table 1 that loss firms have, on average, higher price to book ratios than profit firms. This is consistent with loss firms being in an early stage in their life cycle and/or having more growth potential. 4.7. Accounting Methods and Conservatism In this subsection, we examine the relation between accounting methods employed by firms and conservatism as modeled by Feltham and Ohlson (1996). We consider research and development intensity, depreciation rate, advertising intensity, and the choice of LIFO inventory accounting method (Beaver and Ryan, 2000 and Ahmed, Morton, and Schaefer 2000) as indicators of conservatism associated with accounting methods. We partition our sample into quartiles by research and development intensity (research and development costs divided by sales), depreciation rate (deprecation and amortization expenses divided by the sum of beginning property, plant, and equipment, 17 and intangibles), and advertising intensity (advertising expenses divided by sales). For inventory accounting method, we partition our sample into firms employing LIFO as a primary inventory accounting method and others. Table 11 reports the results of annual regressions for quartiles based on each of the indicators of conservatism. These analyses are based on samples of firm years that have data for the respective accounting based indicator. The estimate of the coefficient on change in lagged operating assets is negative (-0.058) for firms that have low research intensity while the estimate of this coefficient for firms with high research intensity is positive (0.017); however, nether of them is significant at the 0.05 level. We do not find significant differences (t-statistic of 0.92) between the estimate of the coefficient on change in lagged operating assets for the low research intensity portfolio and the high research intensity portfolio, suggesting that there is no significant difference in conservatism associated with application of overall accounting rules. Similarly, we do not find significant differences in accounting conservatism associated with the application of accounting rules for depreciation rates, advertising intensity, and inventory accounting method. The estimate of the coefficient on change in cash investments is significantly greater (t-statistic of 4.25) for high research intensity firms than for low research intensity firms suggesting that research expenditures tend to be positive net present value. The estimate of the coefficient on change in cash investments is significantly greater (tstatistic of 4.19) for firms with higher depreciation expense than for firms with lower depreciation expense. A possible explanation for this result may be that higher depreciation rates suggest that more assets have been acquired recently, consistent with higher growth via positive net present value investments. The estimate of the coefficient on change in cash investments is significantly greater (t-statistic of 3.12) for high advertising intensity firms than for low advertising intensity firms suggesting that advertising expenditures tend to be positive net present value. The estimate of the coefficient on change in cash investments is significantly greater (t-statistic of 3.24) for firms that adopt LIFO than for those that use another inventory valuation methods. In other words, the degree of accounting conservatism associated with investment in 18 positive net present value projects tends to be greater for these firms.16 4.8 Feltham and Ohlson (1995) and Accounting Conservatism Both Feltham and Ohlson (1995) and Feltham and Ohlson (1996) incorporate the possibility of accounting conservatism; however, there are subtle differences in modeling accounting conservatism. In this sub-section, we examine the implications of Feltham and Ohlson (1995) for empirical analyses of accounting conservatism. The return regression model based on Feltham and Ohlson (1995) can be expressed as follows: ret jt 0 1 x jt p jt 1 2 x jt p jt 1 3 d jt 1 p jt 1 4 oa jt p jt 1 jt , (6) In regression (6), accounting conservatism is captured by the change in operating assets (oat), which may be compared with regression (5) based on Feltham and Ohlson (1996), in which accounting conservatism is captured by change in cash investments and change in lagged operating assets. Note that, in regression (6), there is no distinction between conservatism due to accounting rules and conservatism associated with investment in positive net present value projects. The change in operating assets can be thought of as the sum of the effects of change in cash investments and change in lagged operating assets since operating assets can be expressed as the weighted sum of lagged operating assets and current cash investments by applying the operating asset relation (OAR) and by representing operating accruals as a multiple of lagged operating asset (Feltham and Ohlson (1996)): oat oat 1 oact cit oat 1 ( 1)oat 1 cit oat 1 cit The return model based on Feltham and Ohlson (1995) can be used to assess the overall effect of accounting conservatism, and provide a simple framework to control for accounting conservatism. Since it does not require the decomposition of change in 16 The results in section 4.3 suggest that the market to book ratio is a good proxy for accounting conservatism. The median market to book ratio is higher for firms with high research intensity, high depreciation rates, and high advertising intensity than for firms with low research intensity, low depreciation rate, and low advertising intensity. However, the median market to book ratio for firms employing LIFO as a primary inventory valuation method (1.49) is lower than that for firms employing other inventory valuation methods (1.71). 19 operating assets into lagged operating assets and cash investments, we can extend our analysis back to earlier years in which cash flow statements are not available. Table 12 reports the results of the examination of accounting conservatism based on the specification of Feltham and Ohlson (1995) for each of years from 1972 through 2001. Consistent with the results in table 5, the estimate of the coefficient on the change in operating assets (0.05) is significantly positive at the 0.01 level, implying that accounting is on average conservative. The estimates of the coefficients on earnings level, earnings changes, and lagged dividends are positive as in table 4. 5. Summary Based on Feltham and Ohlson (1996), we identify two types of accounting conservatism: conservatism due to accounting rules and conservatism associated with investments in positive net present value projects. We add change in lagged operating assets to the Easton and Harris (1991) regression to capture conservatism due to accounting rules (accounting value added), and change in cash investments to capture conservatism associated with investments in positive net present value projects (economic value added). Consistent with conventional wisdom, we find that accounting is conservative. This result has implications for the Easton and Harris (1991) regression of annual stock returns on earnings levels and earnings changes. We show that the estimates of the coefficients on earnings levels and earnings changes are affected by accounting conservatism, and that there is an improvement in the explanatory power with the inclusion of the variables associated with conservatism. We show that the effect of accounting conservatism is related to the ratio of the market value of net operating assets to the book value of net operating assets. Industry analyses show that there is a wide variation in the degree of accounting conservatism across industries. We find that accounting for pharmaceutical industry is more conservative than accounting for other industries. We find that accounting tends to be more conservative for firms reporting losses than for firms reporting profits, and consistent with Basu (1997) we find that accounting tends to be less conservative for firms with negative returns than for firms with non-negative returns. 20 References Ahmed, A.
