Equity Valuation Employing the Ideal versus Ad Hoc - Berkeley-Haas
Equity Valuation Employing the Ideal versus Ad Hoc Terminal Value Expressions* LUCIE COURTEAU, Université Laval JENNIFER L. KAO, University of Alberta GORDON D. RICHARDSON, University of Waterloo Abstract Recently, Penman and Sougiannis (1998) and Francis, Olsson, and Oswald (2000) compared the bias and accuracy of the discounted cash flow model (DCF) and Edwards-Bell-Ohlson residual income model (RIM) in explaining the relation between value estimates and observed stock prices. Both studies report that, with non–price-based terminal values, RIM outperforms DCF. Our first research objective is to explore the question whether, over a five-year valuation horizon, DCF and RIM are empirically equivalent when Penman’s (1997) theoretically “ideal” terminal value expressions are employed in each model. Using Value Line terminal stock price forecasts at the horizon to proxy for such values, we find empirical support for the prediction of equivalence between these valuation models. Thus, the apparent superiority of RIM does not hold in a level playing field comparison. Our second research objective is to demonstrate that, within each class of the DCF and RIM valuation models, the model that employs Value Line forecasted price in the terminal value expression generates the lowest prediction errors, compared with models that employ non–price-based terminal values under arbitrary growth assumptions.

These results imply that researchers should exercise care in interpreting findings from models using ad hoc terminal value expressions. Keywords Financial information; Residual income model; Terminal values; Valuation Condensé Penman et Sougiannis (1998, ci-après P&S) comparaient récemment la distorsion et la précision du modèle d’actualisation des flux de trésorerie (DCF) et du modèle des bénéfices résiduels d’Edwards, Bell et Ohlson (RIM) dans l’explication de la relation entre les estimations de valeur et le cours observé des actions. Utilisant les bénéfices futurs réels comme mesure des bénéfices attendus, P&S (1998) constatent que les erreurs d’évaluation du modèle DCF sur un horizon de 10 ans excèdent largement celles du modèle RIM. Ils attribuent ce résultat au fait que des montants comptabilisés conformément aux PCGR dans le modèle RIM permettent une prise en compte plus rapide de flux de trésorerie futurs, de sorte que leur pertinence à l’égard de la valeur est plus grande que celle des flux de trésorerie ou des dividendes. Francis, Olsson et Oswald (2000) jettent un nouveau regard sur ce parallèle, en recourant à une méthode ex ante et aux prévisions de Value Line (VL), pour conclure à leur tour que, lorsque les valeurs finales ne sont pas fondées sur les prévisions du cours des actions, l’efficacité du RIM est supérieure à celle du DCF. Le premier objectif des auteurs est de vérifier si, sur un horizon prévisionnel de cinq ans, le DCF et le RIM sont empiriquement équivalents, lorsqu’on utilise les expressions de valeur finale théoriquement « idéales » de Penman (1997), dans l’application de chacun des modèles. Ces expressions de valeur nécessitent le cours du marché prévu (P ) au terme de l’horizon prévisionnel et l’excédent de ce cours sur la valeur comptable, pour un système comptable donné. L’équivalence des modèles DCF et RIM pour des horizons finis et dans des conditions idéales, malgré qu’elle soit bien établie en théorie, n’a pas été démontrée dans les études empiriques. Au premier abord, les arguments semblent circulaires : si des prévisions fiables de cours sont disponibles, le modèle d’actualisation des dividendes (DDM) devrait suffire, et il n’est pas nécessaire de recourir au DCF ou au RIM. La chose n’est cependant pas évidente, du fait que les prévisions de cours formulées par le marché ne sont pas observables ; les auteurs utilisent donc les prévisions de cours final de VL comme substitut. Bien que ces prévisions soient loin d’être idéales et qu’elles puissent contenir des erreurs de distorsion ou de mesure (voir Abarbanell et Bernard, 2000), les auteurs font l’hypothèse que toute erreur de distorsion ou de mesure serait un facteur constant dans les comparaisons entre DCF et RIM. Ils supposent également, comme P&S (1998) et Francis et al. (2000), que le marché est efficient. Le deuxième objectif des auteurs consiste à démontrer que les valeurs intrinsèques calculées à l’aide des prévisions de cours final de VL donnent lieu à des erreurs d’évaluation plus modestes que les valeurs intrinsèques déterminées en fonction des expressions de valeur finale improvisées. Les expressions simples de perpétuité, qui supposent que les bénéfices anormaux postérieurs à l’horizon prévisionnel croîtront soit au taux de 0 pour cent, soit au taux nominal d’inflation, ont été amplement utilisées dans les recherches empiriques (par Francis et al., 2000, et par Frankel et Lee, 1998, entre autres). Gebhardt, Lee et Swaminathan (2001) utilisent un procédé de taux de décroissance qui est aussi problématique que CAR Vol. 18 No. 4 (Winter 2001) Equity Valuation Employing Terminal Value Expressions 627 les expressions basées sur la perpétuité, étant donné qu’il suppose que le rendement anormal du capital investi postérieur à l’horizon prévisionnel convergera vers la moyenne du secteur d’activité, sur une période de sept ans. Les auteurs constatent que les valeurs finales sont en moyenne sensiblement sous-évaluées lorsque des estimations improvisées de l’achalandage au terme de l’horizon prévisionnel sont utilisées, ce qui suppose que les estimations de la valeur intrinsèque (Frankel et Lee, 1998) ou du coût du capital ex ante (Gebhardt et al., 2001) sont sous-évaluées lorsque de telles expressions de valeur finale sont employées. Ces inférences peuvent être importantes, selon le but visé par la recherche, et elles demeurent valides même dans les dernières années de la période étudiée, une fois que s’est atténué l’optimisme de VL dans les prévisions de cours. L’échantillon des auteurs compte 422 sociétés (ou 2 110 exercices-société), à l’égard desquelles ils disposent de données prévisionnelles et historiques complètes pour toute la durée de la période couverte. Le fait que l’échantillon soit constant et que les mesures se répètent au fil d’une période donnée pour les mêmes sociétés retient l’attention des auteurs qui empruntent la méthodologie de l’échantillon constant (voir Kmenta, 1986) exploitant les autocorrélations dans les données pour réaliser certains tests statistiques. Le coût des capitaux propres est calculé à l’aide du modèle d’évaluation des actifs financiers. Le taux sans risque est mesuré comme étant le taux constant à l’échéance des bons du trésor de cinq ans, au début du mois de prévision, provenant de la base de données de la Chicago Federal Reserve Bank, et la prime de risque est mesurée comme étant le produit du bêta de l’entreprise fourni par VL et de la prime de marché historique approximative de 6 pour cent. Les auteurs utilisent les premières prévisions complètes de VL, habituellement publiées au troisième trimestre de l’exercice de l’entreprise. À l’instar de Francis et al. (2000), les auteurs actualisent les prévisions de VL pour les attributs d’évaluation du n e exercice en utilisant un facteur de (n − 1 + f ), où f représente la portion d’exercice se situant entre la date où sont faites les prévisions et la clôture du premier exercice. Étant donné que tous les modèles d’évaluation exigent des valeurs comptables à la date de la prévision, ce que VL ne fournit pas directement, il faut intrapoler les valeurs comptables (les actifs financiers nets) à cette date pour le RIM (le DCF), à partir de leur valeur au début de l’exercice de prévision et des prévisions de VL relatives aux variables de l’exercice courant. VL publie des prévisions pour trois horizons : l’exercice en cours (soit l’exercice 1), l’exercice suivant (soit l’exercice 2) et le long terme (soit l’exercice 5). Étant donné que les prévisions annuelles des attributs d’évaluation pour les exercices 3 et 4 ne sont pas publiées dans le Value Line Investment Survey, à la suggestion des analystes de VL, les auteurs intrapolent de façon linéaire les données relatives à ces deux exercices, en fonction de la croissance prévue entre l’exercice 2 et l’exercice 5. Le cours le plus récent rapporté par VL est utilisé dans cette étude comme variable dépendante. Dans le cas du RIM comme dans celui du DCF, le chercheur doit parfois faire face à la situation où les valeurs finales sont négatives. Le cas peut se produire si l’un ou l’autre des excédents prévus du cours sur la valeur comptable, compte tenu des prévisions de cours final ou des attributs de l’évaluation au terme de l’horizon prévisionnel, est négatif. Les auteurs choisissent de ne pas plafonner les valeurs finales négatives à zéro parce que tout attribut négatif au terme de l’horizon prévisionnel devrait être intégré dans le cours du marché en vigueur. Les tests statistiques révèlent que, pour l’ensemble de l’échantillon, les erreurs prévisionnelles absolues médianes sont de 13,71 pour cent et de 14,18 pour cent respectivement CAR Vol. 18 No. 4 (Winter 2001) 628 Contemporary Accounting Research pour le DCF et le RIM. Ainsi, en mettant l’accent sur la précision, on ne constate pas de supériorité du RIM sur le DCF lorsque les valeurs finales idéales sont employées. Toute « mise à l’épreuve » du RIM et du DCF risque de placer ce dernier en situation défavorable en raison des limites inhérentes à l’estimation de la version de Copeland et al. (1995) du modèle financier des flux de trésorerie disponibles, une méthode employée par Francis et al. (2000) qui fait appel aux données de VL. Pour résoudre ce problème, les auteurs estiment la version du DCF proposée par Penman (1997). Cette spécification particulière convient mieux aux données de VL parce que l’attribut d’évaluation — les flux de trésorerie disponibles aux actionnaires ordinaires — peut être tiré directement des données VL et qu’il n’est pas nécessaire d’estimer le coût moyen pondéré du capital. Les auteurs formulent néanmoins une mise en garde : l’application de la version du DCF proposée par Penman, qui fait un usage empirique des données de VL, peut encore contenir des erreurs de mesure étant donné que VL ne fournit pas de prévisions relatives aux impôts sur le revenu reportés ou aux sommes immobilisées dans le fonds de roulement. Compte tenu de ces limitations pratiques de l’estimation du DCF, il est assez remarquable d’avoir pu établir une équivalence approximative entre le DCF et le RIM. Mettant en opposition les valeurs intrinsèques des modèles qui utilisent les prévisions de cours final et les valeurs intrinsèques des modèles qui ne le font pas, les auteurs constatent que, tant pour le DCF que pour le RIM, l’efficacité des modèles d’évaluation basés sur les prévisions de cours surpasse de beaucoup celle des modèles correspondants qui ne s’appuient pas sur les cours. Bien sûr, l’utilisation des prévisions de cours VL comme point de repère n’est pas valide si ces prévisions sont optimistes. Toutefois, même pour les deux dernières années incluses dans l’étude (1995 – 1996), au moment où l’optimisme des prévisions de cours de VL se trouve ramené à un niveau négligeable, l’erreur prévisionnelle médiane continue d’indiquer une importante distorsion à la baisse lorsque les expressions improvisées de valeur finale sont utilisées. Ces résultats donnent à penser que les chercheurs qui étudient le coût du capital ex ante ou les stratégies d’investissement faisant appel aux expressions simplifiées de valeur finale pour le RIM devraient interpréter leurs résultats avec une certaine prudence. En remplaçant les prévisions de cours final de VL par des expressions traditionnelles de valeur finale à l’aide d’estimations de croissance simples, semblables à celles qu’emploient P&S (1998) et Francis et al. (2000), les auteurs sont en mesure de reproduire les constatations précédentes selon lesquelles le RIM surpasse le DCF en efficacité. Ainsi, dans la régression des cours en vigueur en fonction des valeurs intrinsèques, la valeur de R2 est supérieure dans le cas du RIM comparativement au DCF (par exemple, 79,65 pour cent contre 67,95 pour cent, et 77,02 pour cent contre 60,46 pour cent, lorsque les hypothèses de croissance sont respectivement de 0 et de 2 pour cent). La supériorité du RIM sur le DCF lorsque la valeur finale idéale n’est pas disponible est expliquée par P&S (1998) dans les termes suivants : la valeur comptable actuelle des capitaux propres inclut déjà une partie des flux de trésorerie futurs et laisse relativement peu de valeur à encaisser au terme de l’horizon prévisionnel. Par exemple, selon l’hypothèse de croissance de 0 pour cent (2 pour cent), 20,77 pour cent (25,53 pour cent) de la valeur intrinsèque dans le cas du RIM est dérivée de la valeur finale actualisée, le chiffre correspondant dans le cas du DCF étant de 91,81 pour cent (93,19 pour cent). Lundholm et O’Keefe (2001, ci-après L&O) relèvent des erreurs dans l’application des modèles du RIM et du DCF qui se soldent par des estimations incohérentes de la valeur CAR Vol. 18 No. 4 (Winter 2001) Equity Valuation Employing Terminal Value Expressions 629 intrinsèque. Bien que leurs travaux mettent surtout en relief l’importance d’éviter ces écueils, L&O affirment que l’équivalence du RIM et du DCF est « assurée ». L’équivalence du RIM et du DCF lorsqu’on emploie les expressions de valeur finale idéale, ne peut se confirmer que si 1) la même prévision des cours de VL est utilisée dans les deux modèles et si 2) le chercheur évite les écueils évoqués par L&O. L’un des écueils qu’évoquent L&O, sans proposer de solution pratique, est celui de la difficulté de l’estimation du coût moyen pondéré du capital pour le modèle DCF. La version Penman du modèle DCF utilisée par les auteurs minimise le risque d’erreurs dans l’application du modèle DCF et n’exige pas l’estimation du coût moyen pondéré du capital. Fait d’égale importance, elle ne fait pas intervenir l’hypothèse traditionnelle des versions empiriques précédentes du modèle des flux de trésorerie disponibles selon laquelle les actifs financiers nets sont comptabilisés à la valeur du marché. S’ils ne le sont pas, le chercheur doit enrichir le modèle traditionnel des flux de trésorerie disponibles en y ajoutant un terme qui représente la différence entre la juste valeur et la valeur comptable des actifs financiers nets. Sans ce terme, l’équivalence entre le DCF et le RIM ne peut être démontrée. Un autre des apports de cette étude est qu’elle indique aux chercheurs comment réduire au minimum les incohérences dans l’estimation des valeurs intrinsèques grâce à l’utilisation des données de VL dans l’application du modèle DCF. Les questions de recherche de cette étude ont une pertinence pratique. L’équivalence du DCF et du RIM est tenue pour acquise par ceux et celles qui étudient l’analyse des états financiers, et la démonstration empirique de cette équivalence est utile. Bien sûr, dans le cas d’un horizon fini, l’équivalence n’est possible qu’avec des prévisions de cours final, faute de quoi il convient de déterminer avec soin la longueur de l’horizon prévisionnel et la forme de l’expression de la valeur finale axée sur les cours, ainsi que l’ont démontré les travaux antérieurs. 1. Introduction Recently, Penman and Sougiannis (1998; hereafter P&S) compared the bias and accuracy of the discounted cash flow model (DCF) and Edwards-Bell-Ohlson residual income model (RIM) in explaining the relation between value estimates and observed stock prices. Using a perfect foresight approach, P&S find that valuation errors for DCF over a 10-year horizon exceed those of RIM by a substantial margin. They attribute this result to generally accepted accounting principles (GAAP)-based accounting accruals under RIM, which bring future cash flows forward and hence are more value-relevant than either cash flows or dividends. Francis, Olsson, and Oswald (2000) take a second look at that comparison using an ex ante approach and Value Line (VL) forecasts and also conclude that with non – price-based terminal values RIM outperforms DCF. Our first research objective is to explore whether, over a five-year valuation horizon, DCF and RIM are empirically equivalent using Penman’s (1997) theoretically “ideal” terminal value expressions in each model. These expressions require the market’s expected stock price (P) at the horizon and the premium of that price over book value for a particular accounting system. The equivalence of DCF and RIM for finite horizons under ideal conditions, though well established theoretically, has not been demonstrated in the empirical literature. At first glance, the arguments seem circular: if one has reliable price forecasts, the dividend discount CAR Vol. 18 No. 4 (Winter 2001) 630 Contemporary Accounting Research model (DDM) should suffice and one does not need DCF or RIM. However, the point is not obvious because the market’s stock price expectations are not observable, and we use VL’s terminal stock price forecasts as a surrogate. Although VL terminal price forecasts are far from ideal and may contain bias/measurement error (see Abarbanell and Bernard 2000), we invoke the assumption that any bias/ measurement error will be a constant factor in comparisons across DCF and RIM. Market efficiency is a maintained assumption in our study, as it is in P&S 1998 and Francis et al. 2000. Our second research objective is to demonstrate that intrinsic values calculated using VL terminal stock price forecasts produce smaller valuation errors than intrinsic values employing ad hoc terminal value expressions. Simple perpetuity expressions that assume that post-horizon abnormal earnings will grow at either a rate of 0 percent or the rate of nominal inflation have been widely employed by empirical researchers (e.g., Francis et al. 2000 and Frankel and Lee 1998). Gebhardt, Lee, and Swaminathan (2001) use a fade rate procedure that is also ad hoc in that it assumes that post-horizon abnormal return on equity will converge to the industry average over a seven-year period beyond the forecast horizon. We find that terminal values are on average substantially understated using ad hoc estimates of horizon goodwill, implying that estimates of intrinsic value (Frankel and Lee) or the ex ante cost of capital (Gebhardt et al.) are understated when ad hoc terminal value expressions are used. These inferences can be important depending on the intended research purpose, and hold even in the latter years of our sample when the optimism in VL stock price forecasts has abated. Lundholm and O’Keefe (2001, hereafter L&O) identify errors in application of the RIM and DCF models that lead to inconsistent estimates of intrinsic value. While much of their paper emphasizes the importance of avoiding these pitfalls, L&O assert that the equivalence of RIM and DCF is “guaranteed” to hold. The equivalence of RIM and DCF employing ideal terminal value expressions will only hold if (1) the same VL price forecast is used in RIM and DCF; and (2) the researcher avoids the pitfalls discussed in L&O. One pitfall that L&O refer to, but offer no practical suggestion for, is the conundrum of estimating the weighted average cost of capital for the DCF model. We introduce into the empirical literature a version of DCF derived by Penman 1997 that minimizes the potential for errors in applying the DCF model. Specifically, our version of DCF does not require estimates of the weighted average cost of capital (i.e., WACC) and, just as important, it does not invoke the assumption typical of prior empirical versions of the free cash flow model that net financial assets are marked to market. If financial assets are not marked to market, then the researcher must augment the traditional free cash flow model by incorporating a term representing the fair value increment on current net financial assets. If this term is missing, the equivalence across DCF and RIM cannot be demonstrated. Thus, another contribution of our study is to show researchers how to minimize inconsistent estimates of intrinsic values using VL data to estimate the DCF model. Our research questions have practical importance. The equivalence of DCF and RIM is something students of financial statements analysis take “on faith” and CAR Vol. 18 No. 4 (Winter 2001) Equity Valuation Employing Terminal Value Expressions 631 the empirical demonstration of this equivalence is useful. Of course, for a finite horizon, the equivalence is possible only with terminal stock price forecasts. Without such forecasts, careful attention must be paid to the length of the forecast horizon and the form of the non–price-based terminal value expression, as prior literature has shown. We inherit the focus on pricing errors and the maintained assumption of market efficiency from the “horse race” conducted by P&S 1998 and Francis et al. 2000. Our aim is to revisit the setting of these studies and set the record straight on the apparent superiority of RIM over DCF, employing a level playing field where both models use an approximation of ideal terminal values. The pricing error approach seemingly conflicts with the rationale for VL and fundamental analysis — that is, to spot mispriced securities. In section 6, we provide suggestions for further research focusing on future excess returns. The remainder of this study is organized as follows. A literature review is provided in section 2. Section 3 lays out the research methodology and hypotheses. The sample selection and measurement issues are discussed in section 4, and the empirical results are presented in section 5. Finally, our summary and conclusions appear in section 6. 2. Literature review The DDM and DCF models are well-known approaches to valuation in the finance literature (see Cornell 1993; Copeland, Koller, and Murrin 1995). RIM is discussed extensively by Ohlson 1995, who shows that theoretically GAAP book values and earnings are valid valuation attributes. Feltham and Ohlson (1995) establish the theoretical equivalence of DDM, DCF, and RIM for infinite valuation horizons. All three models follow from the familiar present value of expected dividends (PVED) expression for value, and the last two models substitute out dividends in PVED for relevant valuation attributes.1 Penman (1997) establishes the theoretical equivalence of DDM, DCF, and RIM for finite valuation horizons, provided one that has access to data necessary to estimate the following “ideal” terminal values at the end of forecast horizon T: E t (Pt + T) for DDM; E t (P − B) t + T for RIM; and E t (P − FA) t + T for DCF. In the above, E t (·) denotes market expectations at time t; Pt + T and Bt + T denote forecasted stock price and book value of owner’s equity at the horizon T periods hence; and FA t + T denotes forecasted net financial assets at the horizon. In his paper, Penman does not anticipate that the researcher would have access to forecasts of stock price at the horizon, and hence much of his paper discusses possible estimates of terminal values for each of the DDM, DCF, and RIM models when forecasted stock price is unavailable. One of the objectives of our research is to establish Penman’s hypothesized equivalence over a five-year forecast horizon using VL proxies for the above “ideal” terminal values. A potential limitation of this approach is that market expectations can be measured with error using VL forecasts of future stock price and other valuation attributes. An extensive literature exists that suggests that VL earnings forecasts are biased and/or inefficient (see Abarbanell 1991; Abarbanell and Bernard 1992; and Debondt and Thaler 1990). In a similar vein, Botosan CAR Vol. 18 No. 4 (Winter 2001) 632 Contemporary Accounting Research (1997) observes that the optimism in VL’s terminal price forecasts yields implausibly high estimates of the equity cost of capital. On the other hand, other researchers have shown that the accuracy of VL forecasts and their association with stock price changes are comparable to those of other analysts, such as I/B/E/S and Zacks (see Abarbanell 1991; Bandyopadhyay, Brown, and Richardson 1995; Philbrick and Ricks 1991; and Stickel 1992). The advantages of VL forecasts over I/B/E/S are that VL’s long-run “target price range” yields forecasts of stock price at the horizon five years hence, and no similar price forecasts exist in I/B/E/S. Moreover, VL forecasts dividends, earnings, book values, and future cash flows separately; whereas only forecasts of earnings are available in I/B/E/S.2 Forecasts of dividends and book values are required by RIM, and forecasts of future free cash flows are required by DCF. Although VL provides estimates of long-run target price range, neither point nor range estimates of short-run stock price are made. However, in the Value Line Investment Survey, VL publishes a timeliness rank, which is based on a mechanical model (see Foster 1986, 430–2, for details) and represents expected price appreciation over the next 12 months. Many studies have shown that, using VL’s timeliness measure, investors can earn abnormal returns around a three-day publication period (e.g., Copeland and Mayers 1982; Huberman and Kandel 1987). Similarly, Peterson (1995) finds that publication of “stock highlights” by VL elicits positive abnormal returns. Since VL’s long-run target price ranges come from the same underlying data set that generates timeliness ranks and stock highlights, they can be taken seriously even though their usefulness has not been established in the prior literature. In section 4, we elaborate on how VL constructs these long-run target price ranges. In the empirical domain, P&S (1998) and Francis et al. (2000) are the direct antecedents of our work. P&S use a perfect foresight approach and find that valuation errors for DCF over a 10-year horizon are often in excess of 100 percent and, moreover, these errors consistently exceed those of RIM by a substantial margin. This result, according to P&S, may be due to GAAP-based accounting accruals under RIM, which bring future cash flows forward, compared with the DCF model, which “expenses” investment outlays. Francis et al. revisit the issue of model comparison from an ex ante perspective using VL forecasts over a 5-year horizon, and similarly conclude that RIM dominates over DCF. Like Francis et al., we also take an ex ante approach to study the relative performance of RIM and DCF. However, in contrast to Francis et al., we make use of VL terminal stock price forecasts in calculating terminal values for each model, thus avoiding the need either to extrapolate such values from near-term valuation attributes or to assume an ad hoc growth rate, which may or may not correspond to market expectations. Three other extant empirical studies have also employed an ex ante approach to explore the valuation errors associated with RIM. Bernard (1995) uses VL forecasts of (P − B) at the horizon five years hence to measure terminal value, and shows that the intrinsic values for RIM explain 80 percent of the cross-sectional variation in the level of current stock price. Abarbanell and Bernard (2000) examine the importance that the market attaches to the present value of terminal forecasts of (P − B), and find its regression coefficient to be around 0.67, considerably below CAR Vol. 18 No. 4 (Winter 2001) Equity Valuation Employing Terminal Value Expressions 633 the predicted value of unity.3 This result is consistent with the notion that VL terminal price forecasts contain bias/measurement error. Finally, Sougiannis and Yaekura (2001) explore the valuation errors associated with several GAAP-based RIM valuation models using I/B/E/S rather than VL forecast data. For RIM with conventional non – price-based terminal value expressions at a horizon five years hence, they obtain median signed (absolute) valuation errors of − 26 (35) percent. As we will see later, the magnitudes of these errors are comparable to our RIM errors for valuation estimates that do not employ VL terminal stock price forecasts.4 3. Research methodology and hypotheses development Valuation models In this section, we develop the two major classes of valuation models to be tested in the paper, namely, DCF and RIM, by appealing to Penman 1997. These models are based on the following well-known present value of expected dividend model (PVED) for an infinite horizon: ∞ Pt = ∑R –τ Et ( d t + τ ) (1), τ=1 where Pt is the current market price at time t; R denotes one plus the cost of equity capital; dt + τ denotes dividends for each future period, t + τ ; and Et indicates an expectation conditional upon information available at time t . Penman (1997) shows that when the horizon is finite, the intrinsic value, denoted as Wt, under DDM for T periods hence is given by: T Wt (DDM) = ∑R –τ E t ( d t + τ ) + R −T Et(Pt + T) (2), τ=1 where Pt + T is the market’s forecasted price at the horizon, t + T. It is an ideal terminal value for DDM. DCF model The following clean surplus relation (CSR) is assumed to hold for net financial assets at time t + τ, t = 1, 2, … , T: FA t + τ = FA t + τ −1 + Ct +τ − It +τ + it +τ − dt +τ (3), where for each future period t + τ, FA denotes net financial assets (i.e., cash and marketable securities minus debt and preferred equity) and is negative if there is net debt; (C − I ) is operating cash flows minus capital expenditures (i.e., free cash flows generated by operating assets); and i is interest flow from net financial assets, CAR Vol. 18 No. 4 (Winter 2001) 634 Contemporary Accounting Research which represents interest paid (earned), including preferred dividends, if net financial assets are negative (positive). Bringing d t + τ to the left-hand side of (3) and all other expressions to the right, and substituting for E t (d t + τ ) in equation (1), Penman (1997) derives the following version of the DCF model for an infinite horizon: ∞ Wt (DCF) = FA t + ∑R –τ E t [C t + τ − I t + τ + i t + τ − (R − 1)FA t + τ − 1] (4). τ =1 It is important to note that (4) assumes only PVED and CSR for net financial assets, and one can easily revert back to PVED by substituting in the opposite direction. As explained by Feltham and Ohlson 1995, (4) represents the cash accounting model where operating assets are expensed; book value is represented by current net financial assets; and “earnings” are represented by free cash flows from operations, (C − I ), plus (minus) interest income (expense), i. Penman (1997) shows that if one relaxes the assumption of risk neutrality but assumes that net financial assets are marked to market at all times, (4) becomes the familiar free cash flow model: ∞ Wt (DCF) = FA t + ∑ RW Et (C t + τ − I t + τ ) –τ (5), τ =1 where RW denotes one plus the weighted average cost of capital (i.e., WACC). The equation states that the value of owner’s equity equals the sum of the fair values of net financial assets and net operating assets, with the latter represented by the present value of expected future free cash flows.5 Francis et al. (2000) estimate variations of (5). We prefer Penman’s version of the DCF (i.e., (4)) for several reasons. First, (5) requires the estimation of WACC, where the weights must be based on the estimated value of equity and debt, not on either their book value or a target capital structure. On the other hand, (4) requires the equity cost of capital, thus placing DCF on an equal footing with RIM. Second, (5) assumes that FAs are marked to market and, to the extent that fair value does not equal book value, it introduces noise in the intrinsic value expressions. By comparison, (4) does not make that assumption, and implicitly corrects for any fair value increment on debt.6 Finally, (5) requires forecasted operating cash flows (i.e., C − I ), which, unlike forecasts of free cash flows to common (i.e., C − I + i), are not provided by VL. To derive C − I, one needs to remove the effects of interest expense (income), i. This is problematic because VL does not provide forecasts of “i ” to the horizon for either debt or preferred shares. For an arbitrary finite horizon T, Penman (1997) shows that the ideal terminal value for a finite horizon version of (4) is the market’s expected premium, (P − FA), at the forecast horizon. The following equation represents our DCF model employing VL forecasted price in the terminal value expression: CAR Vol. 18 No. 4 (Winter 2001) Equity Valuation Employing Terminal Value Expressions T Wt (DCF1) = FA t + ∑R –τ τ =1 E t [C t + τ − I t + τ + i t + τ − (R − 1)FA t + τ 635 − 1] + R −T Et (Pt + T − FA t + T) (6a). The expression (Pt + T − FAt + T) at the horizon captures the present value of posthorizon operating cash flows because the cash accounting model expenses operating assets. It also captures any post-horizon fair value increment, if net financial assets are not marked to market. When a terminal stock price forecast is not available, it is of interest to explore other non–price-based expressions. Following Frankel and Lee 1998, P&S 1998, and Francis et al. 2000, we employ two expressions: one assumes a simple perpetuity without growth and the other assumes a perpetuity with constant growth rate g = 2 percent.7 Modifying (6a) accordingly results in: T Wt (DCF0) = FA t + ∑R –τ E t [C t + τ − I t + τ + i t + τ − (R − 1)FA t + τ − 1] τ =1 + R−T (R − 1) −1E t [C t + T + 1 − I t + T + 1 + i t + T + 1 − (R − 1)FA t + T ] T Wt (DCF2) = FA t + ∑R –τ E t [C t + τ − I t + τ + i t + τ − (R − 1)FA t + τ (6b); − 1] τ =1 + R−T (R − 1 − g) −1E t [C t + T + 1 − I t + T + 1 + i t + T + 1 − (R − 1)FA t + T ] (6c). We compute the numerator of the ad hoc terminal value expression as [C t + T + 1 −I t + T + 1 + i t + T + 1 − (R − 1)FA t + T] = (1 + g) (C t + T − I t + T + i t + T) − (R − 1)FA t + T. For the purposes of estimating (6a)–(6c), and (7a)–(7c) discussed next, all variables are deflated by the number of shares outstanding at the end of forecast year.8 RIM model Penman (1997) shows that, for a finite horizon T, the ideal terminal value for RIM is the market’s expected premium, (P − B), at the forecast horizon. This expression represents the present value of post-horizon abnormal earnings (i.e., subjective goodwill) and reflects the joint effects of positive net present value projects and accounting conservatism. Since VL explicitly forecasts book value five years hence, the expected premium can be calculated to yield the following “best” contender from the RIM family of valuation models: CAR Vol. 18 No. 4 (Winter 2001) 636 Contemporary Accounting Research T Wt (RIM1) = Bt + ∑R –τ a E t ( X t + τ ) + R −T E t (Pt + T − B t + T ) (7a), τ =1 a where X t + τ denotes abnormal income for forecast year t + τ, measured as VL’s forecasted net income minus a charge on the capital employed (i.e., R − 1 times opening B ). The corresponding expressions that do not employ terminal price forecasts are: T Wt (RIM0) = B t + ∑R –τ a a E t ( X t + τ ) + R −T(R − 1) −1 Et( X t + T + 1) (7b), τ =1 T Wt (RIM2) = Bt + ∑R –τ a a E t ( X t + τ ) + R −T(R − 1 − g) −1 Et( X t + T + 1) (7c), τ =1 a where X t + T + 1 = (1 + g)Xt + T − (R − 1)Bt + T , under the assumptions of a simple perpetuity with constant growth. Hypotheses development Following P&S 1998 and Francis et al. 2000, we focus on comparing the signed and absolute prediction errors across DCF and RIM. We do not consider DDM in this paper because our price-based DCF model (i.e., (6a)) is developed directly from the corresponding DDM (i.e., (2)) given the financial assets continuity account (i.e., (3)) for each pre-horizon year, thus guaranteeing their theoretical and empirical equivalence.9 The empirical comparison between DCF and RIM that employ Penman’s 1997 ideal price-based terminal value expressions (i.e., (6a) and (7a)) is, however, complicated by the presence of several additional sources of inconsistency, which may or may not be easily avoided by the researcher, as discussed in the introduction and elaborated further in section 5. The equivalence of these two models is not guaranteed empirically unless errors in implementing each model are carefully considered and minimized. We conjecture that, in the absence of implementation errors, the choice between DCF and RIM should be a matter of indifference. This is formalized in our first hypothesis (stated in the null form): HYPOTHESIS 1. Across the versions of DCF and RIM that employ VL forecasted price in the terminal value expression, there is no difference in prediction errors. We next compare non – priced-based models under 0 percent and 2 percent constant growth assumptions with the corresponding price-based models within the same class of DCF and RIM. We expect the model that uses VL’s price forecasts in CAR Vol. 18 No. 4 (Winter 2001) Equity Valuation Employing Terminal Value Expressions 637 the terminal value expressions (i.e., (6a) and (7a)) to beat other contenders within their class (i.e., (6b) – (6c) for DCF; and (7b) – (7c) for RIM). Intuitively, if the researcher cannot observe VL’s post-horizon expectations, any non – price-based terminal value calculated under an arbitrary growth assumption is at best ad hoc. The above discussion leads to our second hypothesis (stated in the alternative form): HYPOTHESIS 2. Within each class of the DCF and RIM valuation models, the model that employs VL forecasted price in the terminal value expression generates the lowest prediction errors, compared with models that employ non – price-based terminal value under arbitrary (0 percent and 2 percent) growth assumptions. It is worthwhile pointing out that Hypothesis 2 is also not “guaranteed” empirically. For example, if VL’s price forecasts are pure noise or if VL simply applies the reciprocal of the equity cost of capital at the horizon and multiplies this by forecasted earnings five years hence, then the forecasted price would fail to capture subjective goodwill beyond the horizon. In this case, (7a) will have no edge over (7b) or (7c),10 and the superiority result predicted in Hypothesis 2 is generally not assured. 4. Data description and measurement issues Data description Our initial sample consists of 500 firms (or 2,500 firm-year observations), which were followed by VL over a five-year period, 1992–96, and were on both CRSP and COMPUSTAT during that time. This sample size is chosen for practical considerations because the forecasts of prices, book values, dividends, cash flows, and other relevant accounting valuation attributes are not available from machinereadable sources and must be hand-collected from the archived Value Line Investment Survey. To draw the sample, we first obtain an intersection of 1,089 firms, excluding those in the financial services sector, from the 1996 coverage of VL, CRSP, and COMPUSTAT, and then apply a random number generating procedure. We require five years of forecast data for all firms included in the sample. Nonforecast-related historical data are extracted from the Value Line Data File. Due to missing data in the data file, 36 firms are eliminated, 41 firms are dropped because VL’s annual capital investment estimates are not provided for some industries,11 and another firm is deleted because VL did not provide price forecasts for one of the years (i.e., 1996). This leaves us with a final sample of 422 firms (or 2,110 firm-years), each with complete forecasted and historic data over the entire sample period under investigation. The panel nature of the data with repeated measures over calendar time for the same firms appeals to us, and panel data methodology (see Kmenta 1986) exploiting autocorrelations in the data will be used for formal statistical tests. Our sample firms are large, with mean (median) market capitalization of $4.95 ($1.18) billion. The minimum market capitalization is $25.80 million, and the CAR Vol. 18 No. 4 (Winter 2001) 638 Contemporary Accounting Research maximum is $16.87 billion. Firm-specific betas provided by VL range from a low of 0.05 to a high of 2 with the mean beta given by 1.02. The equity cost of capital is computed based on the CAPM. The riskless rates are measured as the five-year treasury constant maturity rates at the beginning of the forecast month from Chicago Federal Reserve Bank data base and the risk premiums are measured as the product of VL firm-specific betas and the approximate historical equity premium of 6 percent.12 The cost of equity has a mean of 12.28 percent and the minimum and maximum of 5.69 percent and 18.64 percent, respectively. Measurement issues To measure the variables described in (6a)–(6c) and (7a)–(7c) for each of the five sample years, we take the first complete published VL forecasts, which typically appear in the third quarter of the firm’s fiscal year. Following Francis et al. 2000, we discount VL forecasts of the nth year’s valuation attributes by a factor of (n − 1 + f ), where f reflects the fraction of year between the market valuation date and the first fiscal year-end.13 Since all the valuation models require book values at the date of forecast, which VL does not directly provide, we need to interpolate book values (net financial assets) to the forecast date for the RIM (DCF) models based on their values at the beginning of forecast year and the VL forecasts of related current fiscal year’s variables.14 Our conversations with VL personnel indicate that VL analysts’ predictions of the target stock price range, three to five years ahead, are not mechanical. Judgement is required of the analyst at three stages in constructing the target price range. First, judgement is used to forecast projected earnings three to five years ahead. Second, judgement is used in applying the appropriate P/E ratio to forecasted earnings, and the P/E ratio can deviate from the projected average P/E ratio for the market according to the analysts’ long-term growth projections for the stock in question. Third, judgement is applied in selecting one of five possible range categories to surround a point estimate of forecasted price, with smaller ranges associated with greater financial strength/safety as assessed by the VL analyst and her supervisors. We conclude from these conversations that the width of target stock price ranges reflects uncertainty, and that such price forecasts impound the VL analysts’ growth assumptions beyond the horizon. For our purposes, we define the terminal price forecasts, Pt + T , as the mid-point of the target price range. VL publishes forecasts for three horizons: current fiscal year (i.e., year 1), the following fiscal year (i.e., year 2), and long run (i.e., year 5). Since the internal yearby-year forecasts of valuation attributes for years 3 and 4 are not published in the Value Line Investment Survey, at the suggestion of VL analysts, we interpolate data for these two years based on implied straight-line growth from year 2 to year 5.15 The most recent stock price reported by VL is used as the dependent variable in our study.16 For both RIM and DCF, the researcher must confront the occasional existence of negative terminal values. Such values can arise if either forecasted premiums given terminal price forecasts or valuation attributes at the horizon are negative. We choose not to cap negative terminal values at zero because any negative attribute at the horizon is expected to be impounded in current market price. CAR Vol. 18 No. 4 (Winter 2001) Equity Valuation Employing Terminal Value Expressions 639 5. Empirical results Descriptive statistics Table 1 reports the relative importance of the various components of DCF and RIM. Discounted terminal value (DTV) accounts for the majority of intrinsic value in all three versions of the DCF model (i.e., 95.38 percent, 91.81 percent, and 93.19 percent for DCF1, DCF0, and DCF2, respectively).17 The importance of DTV in the DCF models is consistent with prior literature. Copeland, Koller, and Murrin (1995), for instance, document that, for a sample of companies appraised by McKensey and Company, non–price-based DTV amounts to 56 to 125 percent of intrinsic value. The remaining two components of DCF models tend to have opposite signs in our data. Current book value (i.e., FA t ) is, on average, negative, reflecting current net debt; whereas the present value of pre-horizon “free cash flows” coming to treasury from operations (i.e., PV) is positive. Turning to the RIM models, DTV makes up of 52.23 percent, 20.77 percent, and 25.53 percent of intrinsic value for RIM1, RIM0, and RIM2, respectively. These percentages are considerably lower than the corresponding figures for DCF. Conversely, current book value (i.e., B t ) takes on a more significant role in all three versions of RIM than DCF (e.g., 41.04 percent for RIM1 versus −25.71 percent for DCF1), confirming the findings of prior research that more wealth is captured in valuation attributes to the horizon under RIM than under DCF. Within the family of RIM models, Bt is least important and DTV most important when the “ideal” terminal value is employed. For example, Bt (DTV) accounts for 41.04 percent (52.23 percent) of the intrinsic value under RIM1, compared with 68.06 percent (20.77 percent) and 63.97 percent (25.53 percent) under RIM0 and RIM2, respectively. However, even for RIM0 and RIM2, DTV represents more than 20 percent of the intrinsic value estimates, implying that post-horizon forecasts of abnormal earnings remain crucial to firm valuation under RIM even though, as pointed out by P&S 1998 and Francis et al. 2000, current book value brings future cash flows forward. Two sets of analyses are performed in this study, one based on prediction error defined as the difference between model intrinsic value estimate and current stock price, scaled by current stock price, and the other based on regression analysis. Panels A and B of Table 2 present the distribution of signed and absolute prediction errors, respectively, for the overall sample period. As is evident from the fourth column, the skewness measures are uniformly positive across all valuation models, implying that our data are positively skewed. For the purpose of testing the predictions of Hypotheses 1 and 2, we therefore focus on the median, as opposed to the mean, signed and absolute prediction errors, and use non-parametric Wilcoxon signed rank tests. Some unusually large prediction errors are evident at both ends of the distributions, especially in models for which non–price-based terminal value expressions are employed. The prediction error analysis, in particular that involving Hypothesis 2, may be affected because outliers can come from different firms depending on whether price- or non – price-based models are used.18 To assess potential probCAR Vol. 18 No. 4 (Winter 2001) 640 Contemporary Accounting Research TABLE 1 Relative importance of components of valuation models* DCF1 DCF0 DCF2 RIM1 RIM0 RIM2 Mean opening FA or B† (% of mean IV) Mean PV ‡ (% of mean IV) Mean DTV § (% of mean IV) Mean IV # (% of mean IV) −8.46 (−25.71%) −8.46 (−45.58%) −8.46 (−37.90%) 13.53 (41.04%) 13.53 (68.06%) 13.53 (63.97%) 9.98 (30.33%) 9.98 (53.77%) 9.98 (44.71%) 2.22 (6.73%) 2.22 (11.17%) 2.22 (10.50%) 31.39 (95.38%) 17.04 (91.81%) 20.80 (93.19%) 17.22 (52.23%) 4.13 (20.77%) 5.40 (25.53%) 32.91 (100.00%) 18.56 (100.00%) 22.32 (100.00%) 32.97 (100.00%) 19.88 (100.00%) 21.15 (100.00%) Notes: * See the appendix for a description of DCF1, DCF0, DCF2, RIM1, RIM0, and RIM2. † FA is the net financial assets per share (i.e., cash and marketable securities minus debt and preferred equity), and B is the book value of owner’s equity per share; ‡ PV is the present value of operating cash flows to common shareholders or abnormal earnings to the horizon, on a per-share basis, under the discounted cash flows (DCF) or residual income model (RIM), respectively. § DTV is the discounted terminal value per share given by the last component under DCF1, DCF0, DCF2, RIM1, RIM0, and RIM2. # IV is the intrinsic value estimates per share under DCF1, DCF0, DCF2, RIM1, RIM0, and RIM2. lems associated with outliers, we conduct the prediction error analysis with and without winsorizing at the 1st and 99th percentile.

RIM1, respectively, overestimate current median stock price of $28, reflecting optimism in VL forecasts noted by Botosan 1997. For both models, the median signed prediction errors decline steadily over time. For example, the median signed prediction errors for DCF1 reduce to 1.43 percent and − 1.95 percent in 1995 and 1996, respectively, from the peak of 11.95 percent in 1992. Thus, VL optimism appears to have completely abated toward the end of our sample period. These patterns are depicted in Figure 1. For the pooled 1992–96 data, the median intrinsic value estimates and median signed prediction errors for DCF1 and RIM1 are all within a very small neighborhood of one another (i.e., $29.181 versus $29.104; 4.82 percent versus 4.73 percent).

Nevertheless, the Wilcoxon signed rank test performed on percentage errors rejects the prediction of Hypothesis 1 at the 1 percent level. The sensitivity of small median difference to statistical test may be partially explained by the power of test given the large number of observations overall, and by the fact that most (80 percent) of the differences are in the same direction. The support for Hypothesis 1 is considerably stronger when a separate analysis is performed for each of the sample years. In particular, none of the pair-wise comparisons in years 1992 to 1994 rejects the null of no difference (i.e., Hypothesis 1) at the conventional levels of significance. The median absolute prediction errors and pair-wise comparisons based on these errors are presented in panel B of Table 3. For both DCF1 and RIM1, the annual median absolute prediction errors decline from their highest levels in 1992 to the lowest levels by the mid-point of our sample period (i.e., 1994). The trend reverses itself in the second half of the sample period. The prediction of Hypothesis 1 is not rejected in the last three years of the sample period (1994 – 96), but rejected in the first two years (1992–93). Overall, the median absolute prediction errors are 13.71 percent and 14.18 percent for DCF1 and RIM1, respectively. The Wilcoxon signed rank test rejects Hypothesis 1 at the 1 percent level. In short, the evidence presented is largely consistent with the prediction that there is no difference in the median signed or absolute prediction errors across DCF and RIM models (Hypothesis 1), especially when analysis is conducted at the year-by-year level. In testing Hypothesis 1, the researcher is confronted with several potential sources of inconsistency that can lead to differences across valuation models. We now discuss three sources that we avoid. First, we employ Penman’s version of DCF model (i.e., (4)) to avoid L&O’s “inconsistent discount rate error” referred to in the introduction. Thus, even if the equity cost of capital were incorrectly measured, both DCF1 and RIM1 would produce the same incorrect intrinsic value so as not to affect the test of Hypothesis 1. Second, our conversations with VL personnel indicate that, in the Value Line Investment Survey, forecasts of “free cash CAR Vol. 18 No. 4 (Winter 2001) 644 Contemporary Accounting Research Figure 1 Median signed prediction errors for price-based DCF and RIM: Years 1992 to 1996* 0.14 Median signed prediction error 0.12 0.10 DCF1 RIM1 0.08 0.06 0.04 0.02 0.00 −0.02 1992 1993 1994 1995 1996 Year * Signed prediction errors are calculated as ( IV itM − Pit )/Pit , where Pit is the recent stock price published in the VL forecast report; and IV itM is the intrinsic value estimate per share for firm i in year t calculated under M = DCF1 and RIM1, described in the appendix. The graph depicts the median of signed prediction errors for all sample firms in each of the five years under investigation (1992–96). flows” typically increase working capital unless the VL analyst anticipates some other uses for the cash, such as share repurchases or retirement of long-term debt. Value Line ensures internally in their spreadsheets that all projected sources and uses of cash are reconciled through a projected statement of funds, and that CSR holds for FA. Since it is not easy for the researcher to observe where VL has applied funds for a particular firm-year, we create our own FA continuity schedule, starting with opening net FA and building up the next period FA using VL’s forecasts of Ct + τ , It + τ , it + τ , and dt + τ in (3). Effectively, we generate our own forecasts of future FA and do not use VL’s forecasted long-term debt. This procedure guarantees that CSR will hold for our version of forecasted FA, just as it does internally for VL based on our discussions with VL analysts. This adjustment minimizes L&O’s so-called missing cash flows problem. Third, 301 to 770 firm-year observations had negative opening book value of owners’ equity, and hence larger abnormal earnings than reported earnings under RIM1 during the forecast periods t + 1 to CAR Vol. 18 No. 4 (Winter 2001) Equity Valuation Employing Terminal Value Expressions 645 t + 5. However, capping abnormal earnings at forecasted earnings for these firms would introduce inconsistencies in comparisons with DCF. For that reason, we do not impose an upper cap on abnormal earnings. Results reported in this and the next sections are nonetheless essentially the same qualitatively, with or without the capping requirement. For the same reason, we also do not impose a lower bound on the two firm-year observations where RIM1 intrinsic value is negative. Once again, our results are not sensitive to this treatment. We next turn to two sources of inconsistency that we do not avoid. First, for the DCF model, it is not practical for the researcher to adjust forecasted “free cash flows” for sources or uses of cash due to working capital requirements and deferred taxes. Regarding working capital, the cash versus non-cash components of forecasted working capital are not available from VL. For a typical firm in our sample, ignoring cash tied up in working capital overstates free cash flows, whereas not recognizing deferred taxes understates free cash flows. Second, for RIM, we do not force the CSR to hold when forecasted violations of CSR exist because violations of CSR do exist in U.S. accounting principles and, therefore, should exist in expectation.19 If one were to force CSR to hold, the plug would have to go to either forecasted earnings or forecasted equity infusions (i.e., negative dividends). The latter treatment implies that the corresponding DCF model valuation attributes would have to change, leading to an unknown degree of error in the DCF model. Since we do not adjust for these two sources of inconsistency, the empirical equivalence of DCF and RIM is not “guaranteed” to hold. Nevertheless, even without attempting adjustments in these areas, the differences in errors across valuation models, reported in Table 3, are small. Results from tests of Hypothesis 2 Panel A (B) of Table 4 presents results from testing the prediction of Hypothesis 2 that the median signed (absolute) prediction errors are smaller for the price-based valuation models than for the corresponding non–price-based models. For the pooled 1992–96 data, the median signed prediction errors of 4.82 percent (4.73 percent) for DCF1 (RIM1) are considerably closer to zero than −41.34 percent (−37.95 percent) and −30.50 percent (−34.36 percent) for DCF0 (RIM0) and DCF2 (RIM2), respectively (see panel A).20 Wilcoxon signed rank tests of pair-wise differences between the price-based and the non – price-based models within the same family are all significant at the 1 percent level, supporting the prediction of Hypothesis 2 at the overall level. Results are similar and uniformly in support of Hypothesis 2 when analysis is extended to each sample year. For example, focusing on the last two years when VL optimism is minimal and for which use of price-based models as a benchmark is most appropriate, the median signed prediction errors of 2.89 percent and −1.41 percent for RIM1 are smaller than −40.06 percent and − 43.32 percent (− 36.27 percent and − 39.98 percent) for RIM 0 (RIM 2), respectively, again significant at the 1 percent level. Over the same two years, DCF1 is also associated with considerably smaller median signed prediction errors than DCF0 and DCF2 (1.43 percent versus −42.48 percent and −31.07 percent in 1995; −1.95 percent versus −47.81 percent and −37.86 percent in 1996).

Wilcoxon signed rank tests are employed to test the difference in median signed/absolute prediction errors. † Signed prediction errors are calculated as ( IV itM − Pit )/Pit and absolute prediction errors are calculated as | IV itM − Pit |/Pit , where Pit is the recent stock price published in the VL forecast report; and IV itM is the intrinsic value estimate per share for security i in year t calculated under M = DCF1, DCF0, DCF2, RIM1, RIM0, and RIM2, described in the appendix. ‡ Significant at the 1 percent level. Turning to accuracy, for the entire sample period, the median absolute prediction errors for DCF1 and RIM1 are significantly lower than those for the corresponding non–price-based models. The contrast for DCF is 13.71 percent versus 42.81 percent and 35.48 percent, and that for RIM is 14.18 percent versus 38.80 percent and 36.42 percent (see panel B), lending strong support for Hypothesis 2. The results are equally strong at the year-by-year level. Evidence on the relative performance of RIM versus DCF with ad hoc growth assumptions in the terminal value expression is mixed. At an assumed growth rate of 0 percent, RIM is less biased and more accurate than DCF overall (i.e., −37.95 percent versus −41.34 percent; 38.80 percent versus 42.81 percent); whereas the converse is true when the growth rate is assumed to be 2 percent (i.e., −34.36 percent versus −30.50 percent; 36.42 percent versus 35.48 percent). Similar patterns can also be found in each of the five sample years. These results are to be contrasted with analogous pair-wise comparisons between RIM and DCF when the ideal terminal price forecasts are employed. As reported under the heading “Results from tests of Hypothesis 1”, above, RIM1 does not dominate, nor is it dominated by DCF1 for most of the annual comparisons of median signed and absolute prediction errors. Thus, the conclusion by P&S 1998 and Francis et al. 2000 that RIM outperforms DCF would appear to be quite sensitive to the growth assumption made about valuation attributes and the way terminal values are measured. As sensitivity tests of Hypothesis 2, we repeat the analysis under the alternative, albeit similarly ad hoc, growth assumptions of 4 percent, 6 percent, 8 percent, and 10 percent for DCF employed in Francis et al. 2000. The results indicate that the median absolute prediction errors for DCF1 continue to be lower than the corresponding ad hoc growth models. The median differences are −17.41 percent, −24.20 percent, −58.98 percent, and −154.40 percent, respectively, all significant at the 1 percent level. For RIM, we use Gebhardt, Lee, and Swaminatham’s 2001 fade-rate procedure to generate the alternative ad hoc growth assumption. For each sample firm-year observation, the linear fade rate is defined as the rate at which a firm’s abnormal return on equity at the horizon will converge to the industry average evenly CAR Vol. 18 No. 4 (Winter 2001) Equity Valuation Employing Terminal Value Expressions 649 over a seven-year period beyond the forecast horizon. The median difference in absolute prediction errors between RIM1 and the fade-rate-based RIM model (denoted RIMf) is −35.82 percent, in favor of RIM1. The corresponding median signed difference (i.e., RIM1 − RIMf) is 52.07 percent, implying that RIMf seriously understates the post-horizon goodwill projected by VL. Taken together, these results are strongly in support of the prediction of Hypothesis 2, and suggest that the researcher should exercise care in interpreting results based on models that employ ad hoc terminal value expressions, because intrinsic value estimates in these models can be severely downward biased. This observation applies to studies such as Frankel and Lee 1998, who use a simple perpetuity expression for their RIM terminal values to identify mispriced securities and profitable trading strategies; and Gebhardt et al. 2001, who use a simple faderate procedure for their RIM terminal values in order to solve for a firm’s ex ante cost of capital implied by the RIM intrinsic value estimates and current stock price. As with tests of Hypothesis 1, the researcher needs to deal with several potential sources of inconsistency in testing Hypothesis 2. First, we adopt the approach recommended by L&O 2001 to extrapolate valuation attributes in the first year beyond the forecast horizon (see section 3, above). However, we also repeat the analysis using the approach commonly employed in the “horse race” literature by redefining year t + 6 abnormal earnings as year t + 5 abnormal earnings multiplied by (1 + g) (see P&S 1998 and Francis et al. 2000). The results (not reported in a table) are qualitatively the same across these two extrapolation methods. For example, focusing on accuracy, the median absolute prediction errors for RIM2 and DCF2 now become 37.25 percent and 37.42 percent, compared with the corresponding figures of 36.42 percent and 35.48 percent reported previously in panel B of Table 4. The prediction of Hypothesis 2 is once again strongly supported at the 1 percent level, implying that our earlier conclusion about the superiority of models using VL terminal price forecasts over non–price-based models within the same family are robust to the manner in which ad hoc growth rates are applied to the terminal value expressions. Second, 8 (49) firm-year observations have negative intrinsic values under RIM0 (DCF0) and 9 (34) under RIM2 (DCF2). For these firms, unless negative intrinsic values are capped at zero, comparing across the pricebased and non–price-based models would overstate the difference due to limited liability constraints. Notwithstanding this capping requirement, it should be noted that all the results continue to hold when the restriction is relaxed. Third, firms might have reached a steady state prior to the horizon potentially affecting tests of Hypothesis 2. To rule out this possibility, we delete 202 observations whose abnormal earnings change signs from positive to negative before the horizon and repeat the analysis presented in Table 4. The results (not reported in a table) are similar qualitatively. For example, differences in the median absolute prediction errors are −27.09 percent, −18.93 percent, −24.65 percent, and −21.90 percent for DCF1 − DCF0, DCF1 − DCF2, RIM1 − RIM0, and RIM1 − RIM2, respectively. Wilcoxon signed rank tests again all support Hypothesis 2 at the 1 percent level. CAR Vol. 18 No. 4 (Winter 2001) 650 Contemporary Accounting Research Regression analyses Panels A and B of Table 5 report results from the pooled GLS panel regressions of contemporaneous stock prices on intrinsic value estimates for DCF and RIM models, respectively. For this analysis and that reported in Table 6, we use the GLS procedure because standard tests reject homoscedasticity of model residuals obtained from OLS regressions using share-deflated variables.21 The GLS procedure transforms the data to correct for heteroscedasticity and removes autocorrelation from the residuals (Kmenta 1986). While GLS does not correct for cross-sectional correlation in residuals, any such correlation is unlikely to represent a serious departure from standard assumptions, given modest calendar and industry clustering in our sample. Several results from Table 5 confirm the impressions obtained previously. First, as a benchmark model, the results for DCF1 are striking. While the slope coefficient of 0.966 differs significantly from a theoretical prediction of unity at the 1 percent level, the R2 of 93.71 percent suggests that the measurement error resulting from using VL terminal price forecasts as a proxy for market expectations is modest. Second, the R2s of 93.71 percent and 93.04 percent for the DCF1 and RIM1 models are quite close, implying that these models apparently have similar ability to explain cross-sectional variation in current stock price. To test for the pair-wise difference in R2s, we compute the Vuong Z-statistic (Dechow 1994) for DCF1 versus RIM1 and cannot reject the null of no difference at the 5 percent level.22 This result lends further support for the prediction of Hypothesis 1 that, with ideal terminal value expressions, the choice of valuation models is a matter of indifference. Third, the R2s are considerably higher for the price-based models, compared with their non – price-based counterparts. For the DCF models, the former is 93.71 percent, and the latter are 67.95 percent and 60.46 percent for DCF0 and DCF2, respectively. The corresponding figures for RIM are 93.04 percent versus 79.65 percent and 77.02 percent, respectively. Thus, both price-based valuation models appear to be far more successful in explaining the variability of current stock price than the non – price-based models within the same family, a result consistent with the prediction of Hypothesis 2. Fourth, the R2s for the non– price-based RIM models are considerably higher than those for the non–price-based DCF models (i.e., 79.65 percent versus 67.95 percent and 77.02 percent versus 60.46 percent, based on the 0 percent and 2 percent growth assumptions, respectively), implying that RIM is superior to DCF in situations where terminal price forecasts are not available. Panels A and B of Table 6 present evidence on the incremental explanatory power of various components of intrinsic value estimates for the DCF and RIM models, respectively. Comparing across variants within the same family of DCF and RIM valuation models, we find that the overall R2 is at its highest level in DCF1 and RIM1 (i.e., 93.40 percent versus 67.68 percent and 63.66 percent for DCF; 92.79 percent versus 81.11 percent and 80.52 percent for RIM), establishing once again the superiority of price-based models over their non–price-based counterparts (i.e., Hypothesis 2).

At the component level, the incremental explanatory power of DTV is highest when VL price forecasts are used in the terminal value calculations. For instance, DTV explains 45.81 percent (15.38 percent) of the cross-sectional variations in contemporaneous stock prices in DCF1 (RIM1), but only 20.09 percent (3.70 percent) and 16.07 percent (3.11 percent) for DCF0 (RIM0) and DCF2 (RIM2), respectively. These results imply that VL forecasts of (P − FA) or (P − B) are far less noisy than the non – price-based DTVs in capturing post-horizon goodwill, confirming the impression from Table 1 that DTV accounts for the lion’s share of intrinsic value estimates in the price-based valuation models. In both DCF and RIM, the coefficients on DTV are much closer to the theoretical prediction of unity in the price-based models than in the non–price-based models (i.e., 0.942 versus 0.760 and 0.530 for DCF; 0.945 versus 0.630 and 0.457 for RIM). However, the theoretical prediction of unity is rejected for all the slope coefficients at the 1 percent level. When the comparisons are made across families of valuation models, the overall R2s appear to be similar when VL terminal price forecasts are employed (i.e., 93.40 percent and 92.79 percent for DCF1 and RIM1, respectively). A Vuong test fails to reject the null of no difference in R2 between DCF1 and RIM1 at the conventional levels of significance. This result is consistent with the prediction of Hypothesis 1. Similar to the evidence presented in Table 5, the non – price-based RIM models continue to have higher overall R2 than the corresponding DCF, regardless of the growth assumption (i.e., 81.11 percent versus 67.68 percent given 0 percent growth; 80.52 percent versus 63.66 percent given 2 percent growth). CAR Vol. 18 No. 4 (Winter 2001) 654 Contemporary Accounting Research Sensitivity analyses Analysis based on VL’s uncertainty about future stock prices As discussed in section 4, the target price range at the forecast horizon reflects VL’s uncertainty about future stock prices. In particular, uncertainty is directly related to the width of the range. A priori, one would expect to see larger prediction errors and a diminished edge of the price-based valuation models over those that employ non–price-based terminal value expressions, when VL is less certain about the future. To gain some insight into this issue and provide indirect evidence that VL target price forecasts are judgemental in nature, we rank our sample observations pooled over the 1992–96 period in ascending order according to the degree of uncertainty facing VL, where uncertainty is measured as the difference between the two endpoints of the range, scaled by the mid-point. Focusing on accuracy, we first compute the median absolute prediction errors for the top (i.e., most certain) and bottom (i.e., least certain) quartiles. The figures for DCF1 and RIM1 are 12.40 percent versus 16.22 percent and 12.43 percent versus 16.64 percent, respectively. Wilcoxon two-sample tests of pair-wise comparisons across the top and bottom quartiles for each of the two price-based models are all significant at the 1 percent level, implying that VL target price forecasts are less representative of the investor beliefs impounded in the current market price as uncertainty increases. Next, we compute the difference in the median absolute prediction errors between DCF1 and DCF0, and RIM1 and RIM0 within the same quartile. The differences for the top and bottom quartiles are − 29.14 percent and − 22.99 percent (− 27.18 percent and − 18.23 percent) for DCF1 − DCF0 (RIM1 − RIM0), respectively. A negative difference reflects greater representativeness of the pricebased valuation model, compared with the corresponding ad hoc 0 percent growth model. We then contrast the pair-wise differences for the same family across the top and bottom quartiles using a Wilcoxon two-sample test, and find it to be significant for both DCF and RIM models at the 1 percent level. The result is similar for interquartile comparison of RIM1 − RIM2, whereas an analogous comparison of DCF1 − DCF2 is not statistically significant at any conventional level. These results once again suggest a generally declining representativeness edge of pricebased valuation models over their non – price-based counterparts when VL faces greater uncertainty about the future, confirming our earlier understanding based on conversations with VL analysts that VL price forecasts are judgemental, rather than mechanical, in nature. Analysis based on Fama-French industry cost of equity Following the convention in the literature, we have addressed the issue of risk by discounting a stream of future flows of valuation attributes (i.e., cash flows and abnormal earnings) at a risk-adjusted discount rate. As discussed in section 4, each firm’s risk premium is calculated as the product of VL firm-specific beta and an assumed market premium. Feltham and Ohlson (1999) point out that this approach is ad hoc and lacks theoretical foundation. The conceptually preferred method CAR Vol. 18 No. 4 (Winter 2001) Equity Valuation Employing Terminal Value Expressions 655 would involve adjusting valuation attributes for risk and then discounting the resulting expressions at a riskless rate. However, implementing the certainty equivalence approach advocated by Feltham and Ohlson is difficult in practice. As an alternative, we reperform the analysis using Fama and French’s 1997 industry costs of equity. This requires that we first classify our sample firms into one of the 48 industries described in Appendix A of Fama and French (179–81), and then use industry risk premiums from the five-year rolling three-factor model (see last column, Table 7 of Fama and French, 172–3). The results (not reported in a table) are very similar to those reported previously in Tables 3 – 6, and provide comfort that the findings of this study are unlikely to be driven by the way we capture risk. 6. Conclusion Prior studies by Penman and Sougiannis 1998 and Francis et al. 2000 have compared the bias and accuracy of the non–price-based DCF and RIM models, measured in terms of the signed and absolute prediction errors, respectively, and concluded that RIM outperforms DCF. In this study, we provide evidence to show that these findings need not hold when Penman’s 1997 theoretically “ideal” terminal value for each model is employed. Using Value Line terminal stock price forecasts at the horizon to proxy for such values, we explore the empirical equivalence of DCF and RIM over a five-year valuation horizon under the assumptions that any measurement error in VL price forecasts is “neutral” across these valuation models, and that we have avoided the errors that can impede a comparison of such models. For the overall sample, the median absolute prediction errors are 13.71 percent and 14.18 percent for DCF1 and RIM1, respectively. Thus, focusing on accuracy, RIM does not dominate DCF when the ideal terminal values are employed. Contrasting intrinsic values for models employing terminal price forecasts with those that do not, we find that, for both DCF and RIM, the price-based valuation models outperform the corresponding non–price-based models by a wide margin. Of course, using VL price forecasts as the appropriate benchmark is invalid if such forecasts are optimistic. However, even for the last two years of our sample (1995–96) when the optimism in VL price forecasts has abated to a negligible level, our median signed prediction error evidence continues to indicate a serious downward bias when ad hoc terminal value expressions are used. These results imply that researchers who study the ex ante cost of capital or trading strategies using ad hoc terminal value expressions for RIM should exercise care in interpreting their results. Replacing VL terminal price forecasts with conventional terminal value expressions using ad hoc growth estimates, similar to those employed by P&S 1998 and Francis et al. 2000, we are able to replicate their findings that RIM outperforms DCF. For example, when regressing current stock prices on intrinsic values, the R2 is highest in RIM, compared with DCF (e.g., 79.65 percent versus 67.95 percent, and 77.02 percent versus 60.46 percent under 0 percent and 2 percent growth assumptions, respectively). The superiority of RIM over DCF when the ideal terminal value is not available is explained by P&S 1998 as follows: current book values of owner’s equity bring future cash flows forward and leave relaCAR Vol. 18 No. 4 (Winter 2001) 656 Contemporary Accounting Research tively little value to be captured in the conventional terminal value expressions; whereas the DCF model expenses operating assets and defers most of the value to be captured at the horizon. For example, under a 0 percent (2 percent) growth assumption, 20.77 percent (25.53 percent) of intrinsic value for RIM is derived from discounted terminal value, and the corresponding figure for DCF is 91.81 percent (93.19 percent). Any “horse race” between RIM and DCF may be biased against DCF because of the inherent limitations in estimating the Copeland et al. 1995 version of the finance free cash flow model, an approach employed by Francis et al. 2000 using VL data. To address this issue, we estimate a version of DCF introduced by Penman 1997. This alternative specification is better suited to VL’s data because the valuation attribute, free cash flows to common, is available from VL and there is no need to estimate the WACC. Nevertheless, we caution that implementing Penman’s version of DCF empirically using VL data may still contain measurement errors because VL does not provide forecasts of either deferred income taxes or cash tied up in working capital. Given these practical limitations of estimating DCF, it is quite remarkable that we were able to establish the approximate equivalence between DCF1 and RIM1. For students of financial statement analysis, our paper contains several important messages. We agree with P&S 1998 and Francis et al. 2000 that RIM outperforms DCF when ideal terminal values are not available. However, we also show that these models are empirically equivalent given ideal terminal values. Thus, in our view, the main focus of valuation analysis should be improving forecasts of attributes beyond a finite horizon. Post-horizon forecasts of free cash flows or abnormal earnings can easily articulate across valuation approaches and ultimately articulate back to the benchmark model of forecasting the present value of expected dividends. A reliable “set” of post-horizon forecasts of valuation attributes for DCF and RIM gives the analyst the key to valuation, namely, a reliable price forecast at the horizon. Hence, the dilemma over which valuation model to use is replaced by the challenge of forecasting post-horizon valuation attributes. This study has focused on the pricing errors and viewed market efficiency as a maintained assumption. As an avenue for future research, tests for equivalence could be conducted with future excess returns. Under the null of equivalence, valuation models using ideal terminal value expressions should generate mispricing signals (i.e., intrinsic value minus price) that yield identical excess returns when trading strategies are implemented.

R = One plus the cost of equity. Pt + T = VL’s forecasted price at the horizon, t + T. Ct +τ = Operating cash flows, on a per-share basis, for forecast year t + τ. It +τ = Capital expenditures, on a per-share basis, for forecast year t + τ. it +τ = Interest flow from net financial assets for forecast year t + τ, on a per-share basis. It represents interest paid (earned), including preferred dividends, if net financial assets are negative (positive). CAR Vol. 18 No. 4 (Winter 2001) 658 Contemporary Accounting Research a Xt + τ = Abnormal income, on a per-share basis. FAt = Net financial assets per share (i.e., cash and marketable securities minus debt and preferred equity). Bt = Book value of owner’s equity per share. In addition, the numerator of the terminal value expression for the DCF0/ DCF2 and RIM0/RIM2 models is given by: Ct + T + 1 − It + T + 1 + it + T + 1 − (R − 1)FA t + T = (1 + g)(C t + T − I t + T + i t + T) − (R − 1)FA t + T , and a X t + T + 1 = (1 + g) X t + T − (R − 1)Bt + T , respectively. Endnotes 1. The substitution “works” because both DCF and RIM are accounting systems (cash versus accrual accounting) that obey a clean surplus relation. However, the substitution can just as easily occur in the opposite direction such that one ends up back with PVED. The choice between these three models, for infinite valuation horizons, is a matter of indifference. 2. Some caveats are in order. First, as discussed in section 3, VL forecasts cash flows to common, not operating, cash flows. Second, VL’s definition of cash flows ignores deferred income taxes and changes in working capital. These limitations could bias model comparisons against the DCF model. 3. The 0.67 estimate pertains to the sum of present value of forecasted (P − B) and forecasted abnormal earnings for the last three years of the VL forecast horizon. When the second component is separated, the (unreported) valuation coefficient on terminal forecasts of (P − B), according to Abarbanell and Bernard 2000, is only “slightly higher”. 4. The version of our RIM models that is closest to Sougiannis and Yaekura 2001 is RIM2, which assumes a 2 percent growth rate. As reported in section 5, the median signed and absolute prediction errors for our RIM2 model are −34.36 percent and 36.42 percent, respectively, comparable to those documented by Sougiannis and Yaekura using I/B/E/S data. 5. See Proposition 1 of Feltham and Ohlson 1995 for a reconciliation of the RIM and DCF models when infinite horizons and risk neutrality are assumed. 6. The correction is evident since “i” in (4) denotes the interest expense (income) that will be reported at date t + τ . 7. In both cases, the firm is assumed to have reached a steady state at the horizon. The 2 percent growth rate approximates the rate of inflation during our sample period. CAR Vol. 18 No. 4 (Winter 2001) Equity Valuation Employing Terminal Value Expressions 659 8. Implicitly, we assume that the residual cash flows from financial assets grow at the same rate as that generated by operating assets. If financial assets were marked to market, expected financial residual cash flows would be zero, and the terminal value would depend only on operating cash flows. 9. The results for the DDM model (not reported in a table) are in fact exactly the same as those under DCF1, which appear in Tables 3–6. See section 5 for an elaboration. 10. To see this, note that if VL simply employs the reciprocal of the equity cost of capital as a forecasted P/E ratio at the horizon, (7a) will collapse to (7b) because (Pt + 5 − Bt + 5) = Xt + 6 /re − Bt + 5 = (Xt + 6 − re Bt + 5 )/re = X ta+ 6 /re, under the assumption that Pt + 5 = Xt + 6 /re. 11. Sectors affected include retail stores and airlines. 12. When the VL firm-specific beta is missing, the average VL industry beta at the twodigit SIC level is used. The historic market premium of 6 percent is appropriate, according to Ibbotson and Sinquefield 1983. 13. For most of our sample firms, f ’s are given by (1/4), implying that the forecast is generally made in the third quarter. 14. Specifically, the first period abnormal earnings for RIM, covering a fraction of the year from forecast (i.e., evaluation) date to the end of forecast year, are X ta+ 1 = f X t + 1 − [(1 + r) f − 1]Btq , where Btq = Bt + (1 − f )(Xt + 1 − Dt + 1). For DCF, the first period residual financial income is Y ta+ 1 = f (Ct + 1 − It + 1) − [(1 + r) f − 1]FAtq, where FAtq = FAt + (1 − f )(Ct + 1 − It + 1 − Dt + 1). The notation is as defined in the text and summarized in the appendix. 15. VL forecasts to be interpolated using this procedure include cash flows, capital spending, number of common shares outstanding, dividends, and tax rates. In order to preserve CSR in years 3 and 4, we assume that earnings for these two years are equal. Appealing to CSR for years 3 to 5 and solving for Xt + 3 (or equivalently Xt + 4 ), we get Xt + 3 = Xt + 4 = 1⁄ 2 (Bt + 5 − Xt + 5 + dt + 5 − Bt + 2 + dt + 3 + dt + 4 ). 16. We use the most recent VL stock price prior to the forecast date as the dependent variable because it represents the market’s evaluation of the firm at the time when VL generates its forecasts. At that time, the conditioning information set of the market and that of VL are approximately synchronous in time. Allowing the passage of time so that market price impounds VL forecasts would introduce a price influenced by subsequent information not available to VL at the forecast date and hence confound inferences. 17. These percentages are very similar to that for DDM (not reported in a table) where 92.28 percent of intrinsic value comes from DTV, implying that dividend payments to the horizon per se are only value relevant at the margin because they represent wealth distribution rather than wealth creation. 18. The impact on the test of Hypothesis 1 is minimal because there is substantial (i.e., 76 percent) overlap in the firms falling in the extreme distributions of DCF1 and RIM1 models. 19. Note that 258 (or 12.27 percent) of our 2,110 sample observations do not satisfy CSR for book values within ±5 percent of book values. This is consistent with Bushee 2001, who reports that for his sample VL’s expectational data “satisfy” a similar CSR condition about 90 percent of the time. CAR Vol. 18 No. 4 (Winter 2001) 660 Contemporary Accounting Research 20. The corresponding median signed prediction errors in Francis et al. 2000 are −42.7 percent and −28.2 percent for DCF0 and RIM0, respectively. They do not report results for DCF2 and RIM2. 21. The results presented in both tables are based on a subset of the original sample, after deleting 35 observations (or seven firms) with studentized residuals exceeding an absolute value of 2.5. 22. As discussed earlier, the Kmenta 1986 GLS procedure is essentially OLS after transforming the data to remove autocorrelation and heteroscedasticity. Since the Vuong test is appropriate for OLS, it is also appropriate for residuals arising from the final-stage regression. References Abarbanell, J. 1991.
