Dynamic capital structure and the contingent capital option

The financial crisis has emphasized the difficulties for financial companies to raise funds through conventional liabilities. In this environment, hybrid securities are becoming popular. In this paper we study the optimal capital structure of a company issuing a particular type of hybrid security: perpetual contingent capital, i.e., debt that converts into equity under some conditions. A two-period model with endogenous bankruptcy for a company with equity, straight debt and contingent capital is analyzed. We investigate the instrument under different conversion rules: automatic or optimally chosen by equity holders. We show that contingent capital reduces the coupon of straight debt and expected bankruptcy costs but can require a high spread. A trigger imposed by the regulatory authority in terms of par value of debt may induce a little use of contingent capital with an increase of bankruptcy costs.     

OPERATING LEVERAGE AND UNDERINVESTMENT

Using a contingent claims model, we examine the impacts of both operating leverage and financial leverage on a firm's investment decisions in the context of capacity expansion. Our model shows that quasi‐fixed operating costs could significantly mitigate the underinvestment problem for debt‐financed firms. The existing debt induces equity holders to delay equity‐financed expansion because the expanded earnings base will also benefit the debt holders by lowering the bankruptcy risk. The operating costs decrease this type of wealth transfer from equity holders to debt holders by magnifying the bankruptcy risk of the existing debt upon investment. By applying the Cox proportional hazard model on a large sample of publicly traded U.S. firms over 1966–2016, we offer empirical support for the theoretical predictions. The results are robust to various measures of operating leverage.     

The disciplinary role of debt and equity contracts: Theory and tests

We study how equity and debt contracts commit investors to discipline managers. Our model shows that the optimal allocation of debt, equity, and control rights depends on which disciplinary action is more efficient. When the efficient action is managerial replacement, then control rights should be allocated to equity holders, and capital structure should consist of equity and long-term debt. When the efficient action is liquidation, then control rights can be allocated to the manager, and capital structure should consist of equity and short-term debt. We find empirical support to the model's predictions in a sample of leveraged buyout transactions.     

A note on noise in the market for bankrupt firms' securities

The well-documented phenomena of departures from the absolute priority rule (APR) have provoked an important public policy debate over their consequences. Some scholars argue that APR violations increase economic efficiency because they play an important role in the avoidance of inefficient liquidations and also mitigate inefficient risk incentives. Another group argues that APR violations should be abolished because they add greater uncertainty to the security valuation process; that is, they increase noise in security prices. To date, however, no evidence has been presented on the issue of how much noise APR violations add. We develop a theoretical model that allows an empirical test of the effect of APR violations on noise; our results suggest that APR violations importantly increase noise. Indeed, at least 30 percent, and as much as 85 percent of the noise in security prices may be attributable to APR violations. This does not suggest that the beneficial effects of APR violations are nonexistent or unimportant, but it does imply that failing to account for the effect of APR violations on noise in any modelling of optimal bankruptcy rules may lead to a suboptimal design. We also find that the amount of noise in this market appears to have declined over time as more institutional/informed investors have entered the market for bankrupt firms' securities and the effect of change in the bankruptcy law has become clearer, both consistent with the noisy rational expectations hypothesis.     

Optimal Capital Structure,Endogenous Bankruptcy,and the Term Structure of Credit Spreads

This article examines the optimal capital structure of a firm that can choose both the amount and maturity of its debt. Bankruptcy is determined endogenously rather than by the imposition of a positive net worth condition or by a cash flow constraint. The results extend Leland's (1994a) closed-form results to a much richer class of possible debt structures and permit study of the optimal maturity of debt as well as the optimal amount of debt. The model predicts leverage, credit spreads, default rates, and writedowns, which accord quite closely with historical averages. While short term debt does not exploit tax benefits as completely as long term debt, it is more likely to provide incentive compatibility between debt holders and equity holders. Short term debt reduces or eliminates “asset substitution” agency costs. The tax advantage of debt must be balanced against bankruptcy and agency costs in determining the optimal maturity of the capital structure. The model predicts differently shaped term structures of credit spreads for different levels of risk. These term structures are similar to those found empirically by Sarig and Warga (1989). Our results have important implications for bond portfolio management. In general, Macaulay duration dramatically overstates true duration of risky debt, which may be negative for “junk” bonds. Furthermore, the “convexity” of bond prices can become “concavity.”     

运营时滞、债务协商和可转债融资企业投资决策研究

在运营时滞的背景下,将债务协商机制引入到利用股权和可转债融资的上市企业,建立动态模型分析企业的投资问题。数值分析表明：在相同的运营时滞下,如果股东谈判能力较弱（强）,相比于破产清算,债务协商会加速（推迟）投资;项目首次投资成本和股东谈判能力会同时影响运营时滞与企业投资水平之间的关系。当首次投资成本低时,随着运营时滞增加,较强（弱）的股东谈判能力会推迟（加速）投资;当首次投资成本较高时,运营时滞增加会推迟投资,但股东谈判能力越强,推迟程度越小;债务协商可以提高实物期权价值,并且实物期权价值和股东谈判能力成正比,和运营时滞成反比。     

Agency costs,taxes and debt: The UK evidence

This paper provides an empirical examination of the impact of the corporation tax and agency costs on firms' capital structure decisions. Our evidence suggests that the agency costs are the main determinants of corporate borrowing. Consistent with the agency theory, we find that firms that have fewer growth options have more debt in their capital structure. Moreover, our results show that debt mitigates the free cash flow problem and that firms that are more likely to be diversified and less prone to bankruptcy are highly geared. the negative effect of insider shareholding on leverage disappears, however; when all the agency mechanisms are accounted for. In addition, we find that, in the long run, companies that are tax exhausted exhibit significantly lower debt ratios than tax-paying firms. However, in the short run, firms' capital structure decisions are not affected by taxation.     

Valuation of the Firm's Liabilities When Equity Holders Are Also Creditors

Abstract:  This paper presents a tractable structural model whereby controlling equity holders are also among the creditors of the firm. As the firm approaches distress, equity holders can drain the assets of the firm and expropriate other creditors by repaying their credit before bankruptcy. The right of the bankruptcy court to revoke such repayment protects arm's length creditors, reduces the cost of borrowing and induces equity holders to anticipate repayment of their credit. Equity holders decide repayment neither too early nor too late, so as to reduce the risk of repayment revocation by the bankruptcy court. Similar conclusions apply to the preferential repayment of bank loans personally guaranteed by equity holders. The analysis also suggests that callable bearer bonds may be more valuable to equity holders than to other creditors.     

Cash-flow shortage as an endogenous bankruptcy reason

This paper develops a simple model for a leveraged firm and endogenizes the firm’s bankruptcy point by assuming that equity issuance is costly. Equity-issuance costs reflect the difficulties in issuing new equity for firms that are close to financial distress. The resulting model captures cash-flow shortage as a reason to go bankrupt, though the equity value is positive. I analyze the optimal bankruptcy point as well as corporate bond prices and yield spreads for various levels of equity-issuance costs in order to study the impact of different liquidity constraints. Finally, I discuss the consequences on optimal capital structure.     

The Debt Trap: Wealth Transfers and Debt‐Equity Choices of Junk‐Grade Firms

If outstanding debt is risky, issuing equity transfers wealth from equity holders to debt holders. If existing leverage is high and bankruptcy costs are small, this wealth transfer effect outweighs the gains to stockholders from optimizing firm value. Empirically, we find that for investment‐grade firms, higher leverage implies a greater likelihood of issuing equity, as expected in a standard tradeoff model. However, consistent with the impact of wealth transfer effects, for junk‐grade firms, higher leverage implies a greater likelihood of issuing debt. The analysis implies an additional route through which historical shocks determine firms’ financing choices.     

Inside debt renegotiation: Optimal debt reduction,timing, and the number of rounds

This paper develops a model of debt renegotiation in a structural framework that accounts for taxes, bankruptcy costs and renegotiation costs. To our knowledge, all the previous work on debt renegotiation implies an infinite number of renegotiations. This feature preempts the analysis of the optimal number of renegotiations. We address this drawback by incorporating fixed renegotiation costs in a model of multiple renegotiations, hence obtaining a small finite number of renegotiations. Simple analytical formulae are derived for debt and equity, as well as implicit formulae for the coupon reduction, as a result of a backward recursive technique. The results show that the optimal number of renegotiations, the size and the dynamics of the coupon reductions depend critically on the bargaining power of the claimants. Testable empirical implications regarding multiple costly renegotiations are drawn.     

The cost of capital and optimal financing policy in a dynamic setting

This paper revisits the Modigliani–Miller propositions on the optimal financing policy and cost of capital in a dynamic setting. In an environment without taxes and bankruptcy costs, the results are generally consistent with the Modigliani–Miller Propositions 1 and 2. However, the first proposition should be presented and interpreted more carefully, as given firm characteristics, there is only one optimal capital structure. Thus, a firm’s capital structure is relevant. A relaxation of assumptions about either taxes or bankruptcy costs leads to conclusions that are generally different from those in Modigliani and Miller (1958). The model predicts that leverage and sales-to-capital ratios decrease but firm size and capital stock increase with the subjective discount factor of the firm’s manager if there are taxes and bankruptcy costs. The empirical analysis supports these predictions.     

Dividend policy,creditor rights,and the agency costs of debt

We show that country-level creditor rights influence dividend policies around the world by establishing the balance of power between debt and equity claimants. Creditors demand and managers consent to a more restrictive payout policy as a substitute for weak creditor rights in an effort to minimize the firm's agency costs of debt. Using a sample of 120,507 firm-years from 52 countries, we find that both the probability and amount of dividend payouts are significantly lower in countries with poor creditor rights. A reduction in the creditor rights index from its highest value to its lowest value implies a 41% reduction in the probability of paying a dividend, and a 60% reduction in dividend payout ratios. These results are robust to numerous control variables, sample variations, model specifications, and alternative hypotheses. We also show that the agency costs of debt play a more decisive role in determining dividend policies than the previously documented agency costs of equity. Overall, our findings contribute to the growing literature arguing that creditors exert significant influence over corporate decision-making outside of bankruptcy.     

Strategic Debt Service

When firms experience financial distress, equity holders may act strategically, forcing concessions from debtholders and paying less than the originally-contracted interest payments. This article incorporates strategic debt service in a standard, continuous time asset pricing model, developing simple closed-form expressions for debt and equity values. We find that strategic debt service can account for a substantial proportion of the premium on risky corporate debt. We analyze the efficiency implications of strategic debt service, showing that it can eliminate both direct bankruptcy costs and agency costs of debt.     

How Costly Is External Financing? Evidence from a Structural Estimation

We apply simulated method of moments to a dynamic model to infer the magnitude of financing costs. The model features endogenous investment, distributions, leverage, and default. The corporation faces taxation, costly bankruptcy, and linear‐quadratic equity flotation costs. For large (small) firms, estimated marginal equity flotation costs start at 5.0% (10.7%) and bankruptcy costs equal to 8.4% (15.1%) of capital. Estimated financing frictions are higher for low‐dividend firms and those identified as constrained by the Cleary and Whited‐Wu indexes. In simulated data, many common proxies for financing constraints actually decrease when we increase financing cost parameters.     

A MULTIPERIOD MEAN-VARIANCE MODEL OF OPTIMAL CAPITAL STRUCTURE

The continuing interest in the capital structure issue among financial researchers is evidenced by the stream of capital structure models that have appeared in the literature. Much of this research has used a risk-neutral and/or a single-period framework. In this paper, we develop a capital structure model for multiperiod firms and allow for the firm's cash flows to grow over time, for the firm to issue new debt, and for two types of bankruptcy costs to occur. The types of bankruptcy costs that occur are determined by the firm's uncertain operating cash flows and negotiations between the firm and creditors. Risk is priced via the Sharpe-Lintner capital asset pricing model. Multiperiod risk-priced models, we argue, realistically represent actual firms and are thus an important step toward the development of more testable and usable models of capital structure. We execute a demonstration example in which the value of the levered firm achieves a maximum and discuss the steps the firm would take to maximize shareholder wealth within this example. The example illustrates that the value of the firm passes through an interior optimum as the promised debt payment is increased. A simulation of the effect of changes in firm-specific parameters shows that the model exhibits expected and appealing relationships between these parameters and the value of the levered firm.     

TEXTBOOK INCONSISTENCIES IN GRAPHING VALUATION EQUATIONS: A FURTHER NOTE

In this note, the authors demonstrate that if a firm's leverage ratio is measured by debt-to-total value (debt-to-equity) in the pure capital structure rearrangement framework implicit in research reported by Modigliani and Miller (e.g., debt-to-equity exchanges), the market value of levered equity will be a concave (convex) function, and the market value of debt will be a convex (concave) function. These nonlinearities exist even without bankruptcy costs.     

Debt and managerial rents in a real-options model of the firm

We present a theory of capital investment and debt and equity financing in a real-options model of a public corporation. The theory assumes that managers maximize the present value of their future compensation (managerial rents), subject to constraints imposed by outside shareholders’ property rights to the firm's assets. Absent bankruptcy costs, managers follow an optimal debt policy that generates efficient investment and disinvestment. We show how bankruptcy costs can distort both investment and disinvestment. We also show how managers’ personal wealth constraints can lead to delayed investment and increased reliance on debt financing. Changes in cash flow can cause changes in investment by tightening or loosening the wealth constraints. Firms with weaker investor protection adopt higher debt levels.     

The Capital Structure Puzzle: Another Look at the Evidence

Since the formulation of the Miller and Modigliani propositions over 60 years ago, financial economists have been debating whether there is such a thing as an optimal capital structure—a proportion of debt to equity that can be expected to maximize long‐run shareholder value. Some finance scholars have followed M&M in arguing that both capital structure and dividend policy are irrelevant in the sense of having no significant, predictable effects on corporate market values. Another school of thought holds that corporate financing choices reflect an attempt by corporate managers to balance the tax shields and disciplinary benefits of more debt against the costs of financial distress. Still another theory says that companies do not have capital structure targets, but instead follow a financial pecking order in which retained earnings are generally preferred to outside financing, and debt is preferred to equity when outside funding is required. In reviewing the evidence that has accumulated since M&M, the authors argue that taxes, bankruptcy and other contracting costs, and information costs all appear to play important roles in corporate financing decisions. While much, if not most, of the evidence is consistent with the idea that companies set target leverage ratios, there is also considerable support for the pecking order theory's contention that managements are willing to deviate widely from their targets for long periods of time. According to the authors, the key to reconciling the different theories—and thus to solving the capital structure puzzle—lies in achieving a better understanding of the relation between corporate financing stocks (that is, total amounts of debt and equity) and flows (which security to issue at a particular time). Even when companies have leverage targets, it can make sense to deviate from those targets depending on the costs associated with moving back toward the target. And as the authors argue in closing, a complete theory of capital structure must take account of these adjustment costs and how they affect expected deviations from the targets.     

Multiple corporate governance attributes and the cost of capital – Evidence from Germany

This paper investigates the extent to which corporate governance affects the cost of debt and equity capital of German exchange-listed companies. I examine corporate governance along three dimensions: financial information quality, ownership structure and board structure. The results suggest that firms with high levels of financial transparency and bonus compensations face lower cost of equity. In addition, block ownership is negatively related to firms' cost of equity when the blockholders are other firms, managers or founding-family members. Consistent with the conjecture that agency costs increase with firm size, I find significant cost of debt effects only in the largest German companies. Here, the creditors demand lower cost of debt from firms with block ownerships held by corporations or banks. My findings demonstrate that a uniform set of governance attributes is unlikely to satisfy suppliers of debt and equity capital equally.
