A Reconsideration of Tax Shield Valuation

A quarter‐century ago, Miles and Ezzell (1980) solved the valuation problem of a firm that follows a constant leverage ratio L = D/S. However, to this day, the proper discounting of free cash flows and the computation of WACC are often misunderstood by scholars and practitioners alike. For example, it is common for textbooks and fairness opinions to discount free cash flows at WACC with beta input β _S = [1 + (1 ? τ)L]β_u, although the latter is not consistent with the assumption of constant leverage. This confusion extends to the valuation of tax shields and the proper implementation of adjusted present value procedures. In this paper, we derive a general result on the value of tax shields, obtain the correct value of tax shields for perpetuities, and state the correct valuation formulas for arbitrary cash flows under a constant leverage financial policy.     

Capital Cash Flows,APV and Valuation

This paper examines three different methods of valuing companies and projects: the adjusted present value (APV), capital cash flows (CCF) and weighted average cost of capital (WACC) methods. It develops the appropriate WACC and beta leveraging formulae appropriate for each valuation model, so that given a particular valuation model the correct APV and CCF values can be determined from the WACC value and vice versa. Further it goes on to show when the perpetuity formulae give poor estimates of the value of individual cash flows, even though the overall values are correct. The paper cautions that the APV and CCF models require more information than is currently known, such as the value of the corporate use of debt, and consequently can give misleading results, particularly in sensitivity analyses.     

Cash Flow Sensitivity of Investment

Investment cash flow sensitivity is associated with both underinvestment when cash flows are low and overinvestment when cash flows are high. The accessibility of external capital is positively correlated with cash flows, intensifying investment cash flow sensitivity. Managers actively counteract the variations in internal and external liquidity by accumulating working capital when liquidity is high and draining it when liquidity is low. These results imply that cash flow sensitive firms face financial constraints, which are binding in low cash flow years. Traditional indicators of financial constraints, such as size and dividend payout, successfully distinguish firms that may potentially face constraints, but are less successful in distinguishing between periods of tight and relaxed constraints. These periods are much more clearly separated by the KZ index, which, on the other hand, is less successful in identifying firms that are likely to face liquidity constraints.     

The Effect of Venture Capital Financing on the Sensitivity to Cash Flow of Firm's Investments

This work studies the effect of venture capital (VC) financing on firms' investments in a longitudinal sample of 379 Italian unlisted new‐technology‐based firms (NTBFs) observed over the 10‐year period from 1994 to 2003. We distinguish the effects of VC financing according to the type of investor: independent VC (IVC) funds and corporate VC (CVC) investors. Previous studies argue that NTBFs are the firms most likely to be financially constrained. The technology‐intensive nature of their activity and their lack of a track record increase adverse selection and moral hazard problems. Moreover, most of their assets are firm‐specific or intangible and hence cannot be pledged as collateral. In accordance with this view, we show that the investment rate of NTBFs is strongly positively correlated with their current cash flows. We also find that after receiving VC financing, NTBFs increase their investment rate independently of the type of VC investor. However, the investments of CVC‐backed firms remain sensitive to shocks in cash flows, whereas IVC‐backed firms exhibit a low and statistically not significant investment–cash flow sensitivity that we interpret as a signal of the removal of financial constraints.     

Strategic Decision Making of the Firm Under Asymmetric Information

This paper develops a simple signaling model whereby high valuation firm uses levels of investment, debt and dividends to convey information to the market regarding its valuation. Conditions are determined under which investment, debt and dividends are employed in a separating Nash equilibrium. Unlike many other signaling models where the source of asymmetric information concerns only the mean of the firms' cash flow, our model allows for two sources of asymmetric information: the mean and the variance of the cash flow. This paper finds that the choice of signals depends on the relative importance of these two sources of informational asymmetry. For example, we show that high valued firms signal their values by decreasing their debt if the source of asymmetric information is mainly driven by the variance of the cash flows. This latter result differs from the debt signaling models found in the literature. The findings of this paper are consistent with extensive empirical evidence.     

Prediction of Operating Cash Flows: Further Evidence from Australia

This paper examines empirically the relative abilities of current operating cash flows (hereafter OCF) and earnings in predicting future operating cash flows in Australia. It extends prior Australian research on cash flow prediction ( Percy and Stokes 1992 ; Clinch, Sidhu and Sing 2002 ; Farshadfar, Ng and Brimble 2009 ) by examining future cash flow predictions for one‐, two‐ and three‐year‐ahead forecast horizons; incorporating additional contextual variables likely to affect the predictive association between current cash flows or earnings and future cash flows; and comparing cross‐sectional versus time series‐based prediction models to ascertain the relative superiority of one approach over the other. Regression results reveal that the cash flow‐based models are more accurate in predicting future operating cash flows than earnings‐based models. This result, however, is moderated by firm‐specific contextual factors like firm size, negative versus positive cash flow pattern, cash flow variability and firm operating cycle. Finally, a comparison between cross‐sectional and time series approaches reveals that the cross‐sectional model outperforms the time series model for both the operating cash flows and earnings models in most of the forecast years.     

Estimating cost of capital in firm valuations with arithmetic or geometric mean – or better use the Cooper estimator?

We test the extent and determinants of bias effects of the arithmetic as well as the geometric mean estimator and the estimator of Cooper [1996. Arithmetic versus geometric mean estimators: Setting discount rates for capital budgeting. European Financial Management 2 (July): 157–67] regarding discount rate estimation for firm valuation by way of a bootstrap approach for 13 different countries. The Cooper estimator is superior to both the geometric and the (conventional) arithmetic mean estimator. However, a ‘truncated’ version of the arithmetic mean estimator leads generally to better estimation outcomes than the Cooper estimator. This means that, in order to reduce problems of upward-biased firm value estimates, expected cash flows beyond a certain time horizon are completely neglected in terminal value estimation. Such an approach seems particularly reasonable for the valuation of young growth companies as well as for companies from quickly developing countries such as Brazil, China, or Thailand, because the bias in terminal value estimation is increasing in the growth rate of future expected cash flows.     

The Sophisticated and the Simple: the Profitability of Contrarian Strategies

A variety of variables have been used to form contrarian portfolios, ranging from relatively simple measures, like book‐to‐market, cash flow‐to‐price, earnings‐to‐price and past returns, to more sophisticated measures based on the Ohlson model and residual income model (RIM). This paper investigates whether: (i) contrarian strategies based on RIM perform better or worse than those based on the Ohlson model; (ii) contrarian strategies based on more sophisticated valuation models (e.g. Ohlson and RIM) perform much better than the relatively simpler ranking variables that have been used so extensively in the finance literature. Given that the RIM and Ohlson models require greater information inputs and technical know‐how, and make different implicit assumptions on future abnormal earnings, it is important to ascertain if they offer significantly greater contrarian profits to outweigh the increased costs that they entail. Indeed, our surprising finding is that simple cash flow‐to‐price measures appear to do almost as well as the more sophisticated alternatives. One would have expected the sophisticated models to significantly outperform the simple cash flow to price model for the reasons given by Penman (2007) .     

Disclosing to Informed Traders

We develop a model in which a firm's manager can voluntarily disclose to privately informed investors. In equilibrium, the manager only discloses sufficiently favorable news. If the manager is known to be informed but disclosure is costly, the probability of disclosure increases with market liquidity and the stock trades at a discount relative to expected cash flows. However, when investors are uncertain about whether the manager is informed, disclosure can decrease with market liquidity and the stock can trade at a premium relative to expected cash flows. Moreover, contrary to common intuition, public information can crowd in more voluntary disclosure.     

The Changing Landscape of Accrual Accounting

A fundamental property of accrual accounting is to smooth temporary timing fluctuations in operating cash flows, indicating an inherent negative correlation between accruals and cash flows. We show that the overall correlation between accruals and cash flows has dramatically declined in magnitude over the past half century and has largely disappeared in more recent years. The adjusted R ² from regressing (changes in) accruals on (changes in) cash flows drops from about 70% (90%) in the 1960s to near zero (under 20%) in more recent years. In exploring potential reasons for the observed attenuation, we find that increases in non‐timing‐related accrual recognition, as proxied by one‐time and nonoperating items and the frequency of loss firm‐years, explain the majority of the overall decline. On the other hand, temporal changes in the matching between revenues and expenses, and the growth of intangible‐intensive industries play only a limited role in explaining the observed attenuation. Finally, the relative decline of the timing role of accruals does not appear to be associated with an increase in the asymmetrically timely loss recognition role.     

Endogenous Financial Constraint and Investment‐Cash‐Flow Sensitivity

This paper studies a dynamic investment model with moral hazard. The moral hazard problem implies an endogenous financial constraint on investment that makes the firm's investment sensitive to cash flows. I show that the production technology and the severity of the moral hazard problem substantially affect the dependence of the investment‐cash‐flow sensitivity on the financial constraint. Specifically, if the production technology exhibits almost constant returns to scale in capital or the moral hazard problem is relatively severe, the dependence is negative. Otherwise, the pattern is reversed to some extent. Moreover, the calibrated benchmark model can quantitatively account for the negative dependence of investment and Tobin's Q on size and age observed in the data.     

Divisional Informativeness Gap and Value Creation from Asset Sales

Nanda and Narayanan (1999) show that the information asymmetry between the managers and market participants regarding divisional cash flows helps explain the value creation on asset sales. Based on their theoretical framework, the divisional informativeness gap hypothesis predicts that the announcement‐period return increases with the difference in cash‐flow informativeness of retained and divested divisions prior to the divestiture. Our results, using industry‐average earnings response coefficient as a proxy for cash‐flow informativeness of a division, support this prediction. The effect is stronger when a conglomerate retains the division with relatively greater growth opportunities.     

Implementing Fischer Black's Simple Discounting Rule

Corporate managers typically estimate the value of capital projects by discounting the project's expected future net cash flows at the cost of capital. The capital asset pricing model (CAPM) is generally used to estimate that cost. But, as anyone who has worked on the finance or business development staff of a public company can attest, there are major challenges in applying the CAPM, including largely unresolved questions about what constitutes the “market portfolio,” how to estimate market risk premiums, and how to estimate the betas of projects. In a short article published in Financial Management in 1988, Fischer Black proposed a valuation “discounting rule” that avoids all these problems—one that involves discounting a relatively certain (as opposed to an expected or average) level of operating cash flows at the risk-free rate. But Black's article does not address the question of how to calculate these “certainty equivalent” or “conditional” cash flows. In this article, the authors propose a way of implementing Black's rule that involves estimating the “conditional” cash flows in a three-step procedure:

• • Find a benchmark security that correlates with the project's cash flows;
• • Estimate the percentiles of the distribution in which the benchmark return equals the risk-free rate over different investment horizons;
• • Use information from corporate managers to assess the cash flows that define the same percentiles in the cash flow distributions.

As the authors point out, the virtue of Black's rule is that it shifts the focus of the analyst away from the assessment of discount factors and puts it squarely on the more challenging, and arguably more relevant, problem of estimating the project's cash flows.     

Trading imbalances,predictable reversals,and cross-stock price pressure

We test the implications of a multi-asset equilibrium model in which a finite number of risk-averse liquidity providers accommodate non-informational trading imbalances. These imbalances generate predictable reversals in stock returns. An imbalance in one stock also affects the prices of other stocks. The magnitude of the cross-stock price pressure depends on the correlations of the stocks’ underlying cash flows. The model implies that non-informational trading increases the volatility of stock returns. We confirm the model's implications using data from the Taiwan Stock Exchange.     

Hedging,speculation, and shareholder value

We document that gold mining firms have consistently realized economically significant cash flow gains from their derivatives transactions. We conclude that these cash flows have increased shareholder value since there is no evidence of an offsetting adjustment in firms’ systematic risk. This finding contradicts a central assumption in the risk management literature that derivatives transactions have zero net present value, and highlights an important motive for firms to use derivatives that the literature has hitherto ignored. Although we find considerable evidence of selective hedging in our sample, the cash flow gains from selective hedging appear to be small at best.     

Do Investors Expect Mean Reversion in Asset Prices?

We investigate the existence and source of equilibrium mean reversion in UK non-financial and financial asset prices over the period 6 April, 1981, through 31 October, 1995. Our results indicate substantial expected transitory components in commodity and metals markets but report expected mean reversion for financial assets only at the near to maturity horizons. Implied cash flow yields appear to have a role in driving the mean reverting process particularly at short horizons while the role of interest rate movements varied across assets and across maturities. Our results reject the existence of a common risk premium across market term structures.     

Collateral and capital structure

We develop a dynamic model of investment, capital structure, leasing, and risk management based on firms' need to collateralize promises to pay with tangible assets. Both financing and risk management involve promises to pay subject to collateral constraints. Leasing is strongly collateralized costly financing and permits greater leverage. More constrained firms hedge less and lease more, both cross-sectionally and dynamically. Mature firms suffering adverse cash flow shocks may cut risk management and sell and lease back assets. Persistence of productivity reduces the benefits to hedging low cash flows and can lead firms not to hedge at all.     

The Cash Flow Sensitivity of Cash

We model a firm's demand for liquidity to develop a new test of the effect of financial constraints on corporate policies. The effect of financial constraints is captured by the firm's propensity to save cash out of cash flows (the cash flow sensitivity of cash). We hypothesize that constrained firms should have a positive cash flow sensitivity of cash, while unconstrained firms' cash savings should not be systematically related to cash flows. We empirically estimate the cash flow sensitivity of cash using a large sample of manufacturing firms over the 1971 to 2000 period and find robust support for our theory.     

The impact of labor unions on investment-cash flow sensitivity

This paper empirically examines how labor unions affect investment-cash flow sensitivity using samples from the US covering the period of 1984–2009. We find a significant positive union effect using a q model of investment. The capital expenditures of firms are 1.71 times more sensitive to internal cash flows when unionization rates increase one standard deviation from the mean. This effect holds when we control for other proxies of financial constraints. In addition, unionized firms are associated with lower cash–cash flow sensitivity, which suggests that the higher investment-cash flow sensitivity in unionized firms is primarily driven by the incentive of these firms to reduce liquidity and enhance bargaining power against the union. We also show that the above union effects become more pronounced during labor contract negotiation years.     

Accounting comparability and relative performance evaluation by capital markets

This paper examines how accounting comparability affects the monitoring role and the risk allocation role of capital markets. We develop the statistical and informational properties of accounting reports under varying degrees of comparability. A perfectly comparable accounting information system enables investors to perfectly infer the difference between any two firms' future cash flows although investors remain uncertain about either firm's cash flow. Comparability alleviates entrepreneurs' moral hazard problem by strengthening the price response to the relative accounting performance, but can induce excessive price risk as well as residual systematic cash flow risk. Unlike the investors (users) who earn their surplus by bearing the residual systematic risk, the entrepreneurs (preparers) do not find perfect comparability desirable. Hence, a standard setter would mandate higher comparability than preferred by preparers, but not perfect comparability.
