Debt Management under Corporate and Personal Taxation

The presence of long-term debt in a corporation's capital structure is shown to give rise to a valuable tax-timing option that can be exercised by the firm on behalf of its shareholders. This option, which is not available if the firm is fully equity financed, implies that leverage will have a positive tax effect on total firm value even if there is no such effect associated with the tax deductibility of the coupon interest payments on debt. The more volatile interest rates and bond prices are, the more valuable the tax-timing option and the larger the favorable impact of debt on shareholder wealth.     

Corporate Debt Value,Bond Covenants,and Optimal Capital Structure

This article examines corporate debt values and capital structure in a unified analytical framework. It derives closed-form results for the value of long-term risky debt and yield spreads, and for optimal capital structure, when firm asset value follows a diffusion process with constant volatility. Debt values and optimal leverage are explicitly linked to firm risk, taxes, bankruptcy costs, risk-free interest rates, payout rates, and bond covenants. The results elucidate the different behavior of junk bonds versus investment-grade bonds, and aspects of asset substitution, debt repurchase, and debt renegotiation.     

A Framework for Corporate Treasury Performance Measurement

Corporations generally do not have a formal process for evaluating the effectiveness of their treasury departments in managing debt. To the extent that corporate borrowing decisions are predicated on "market timing" rather than matching the interest rate sensitivity of the firm's liabilities to that of its assets, the firm is effectively making bets on interest rates that should be monitored and evaluated.
The author has developed an approach that allows for periodic reporting of treasury's performance to investors and that also provides a framework for treasury to compare and choose among alternatives in the capital markets. The basic idea is to calculate a company's liability return and then establish a benchmark portfolio that allows measurement of relative performance. For a nonfinancial corporation, a useful benchmark can be constructed using the collective debt obligations of the company's industry peers. The assumption underlying this benchmark is that the financing of the industry as a whole is designed to produce an "optimal" asset-liability configuration and net exposure to interest rates.     

The Determination of the Seniority Structure of Debt: Theory and Evidence

The purposes of this paper are to provide a theory of determining the firm's optimal seniority structure of debt and examine the relation between the firm's seniority structure of debt and its characteristics. Unlike previous studies, we develop a theoretical model which explicitly includes the benefits and costs associated with senior debt financing, corporate taxes, risk-aversion in the capital market, and costs of financial distress. We next show how a value-maximized firm searches for the optimal trade-off among the present values of the tax advantage of debt, loss of tax credits, expected costs of financial distress, costs of senior debt financing, and benefit of limited liability. Numerical analysis results show that the firm's value is not only a strictly concave function of its capital structure (with a unique global maximum), but also a strictly concave function of its mix of senior and junior debts (with a unique global maximum). We then show that a firm's optimal seniority structure of debt (i.e. the market value of senior debt divided by the sum of the market values of senior and junior debts) increases for low levels of asset riskiness and decreases when asset riskiness becomes sufficiently great. Our model also suggests that a firm's optimal seniority structure of debt increases for low levels of growth opportunities and decreases for high levels of growth opportunities. We test the predictions of our model on the relation between the firm's seniority structure of debt and its characteristics by using the data for the firms in COMPUSTAT over the 1972 through 1991 time period. The empirical evidence is consistent with our theoretical predictions.     

Do Credit Spreads Reflect Stationary Leverage Ratios?

Most structural models of default preclude the firm from altering its capital structure. In practice, firms adjust outstanding debt levels in response to changes in firm value, thus generating mean-reverting leverage ratios. We propose a structural model of default with stochastic interest rates that captures this mean reversion. Our model generates credit spreads that are larger for low-leverage firms, and less sensitive to changes in firm value, both of which are more consistent with empirical findings than predictions of extant models. Further, the term structure of credit spreads can be upward sloping for speculative-grade debt, consistent with recent empirical findings.     

ESTIMATING THE TAX BENEFITS OF DEBT

The standard approach to valuing interest tax shields assumes that full tax benefits are realized on every dollar of interest deduction in every scenario. The approach presented in this paper takes account of the possibility that interest tax shields cannot be used in some scenarios, in part because of variations in the firm's profitability. Because of the dynamic nature of the tax code (e.g., tax-loss carrybacks and carryforwards), it is necessary to consider past and future taxable income when estimating today's effective marginal tax rate. The paper uses a series of numerical examples to show that (1) the incremental value of an extra dollar of interest deduction is equal to the marginal tax rate appropriate for that dollar ; and (2) a firm's effective marginal tax rate (and therefore the marginal benefit of incremental interest deductions) can actually decline as the firm takes on additional debt.
Based on marginal benefit functions for thousands of firms from 1980–1999, the author concludes that the tax benefits of debt averaged approximately 10% of firm value during the 1980s, while declining to around 8% in the 1990s. By taking maximum advantage of the interest tax shield, the average firm could have increased its value by approximately 15% over the 1980s and 1990s, suggesting that the consequences of being underlevered are significant. Surprisingly, many of the companies that appear best able to service debt (i.e., those with the lowest apparent costs of debt) use the least amount of debt, on average. Treasurers and CFOs should critically reevaluate their companies' debt policies and consider the benefits of additional leverage, even if taking on more debt causes their credit ratings to slip a notch.     

Capital Structure, CEO Dominance, and Corporate Performance

We use agency theory to investigate the influence of CEO dominance on variation in capital structure. Due to agency conflicts, managers may not always adopt leverage choices that maximize shareholders’ value. Consistent with the prediction of agency theory, the evidence reveals that, when the CEO plays a more dominant role among top executives, the firm adopts significantly lower leverage, probably to evade the disciplinary mechanisms associated with debt financing. Our results are important as they demonstrate that CEO power matters to critical corporate outcomes such as capital structure decisions. In addition, we find that the impact of changes in capital structure on firm performance is more negative for firms with more powerful CEOs. Overall, the results are in agreement with prior literature, suggesting that strong CEO dominance appears to exacerbate agency costs and is thus detrimental to firm value.     

Capital Structure,Corporate Taxation and Firm Age*

This paper analyses the relationship between corporate taxation, firm age and debt. We adapt a standard model of capital structure choice under corporate taxation, focusing on the financing and investment decisions typically faced by a firm. Our model suggests that the debt ratio is associated positively with the corporate tax rate and negatively with firm age. Further, we predict that the tax-induced advantage of debt is more important for older firms than for younger ones. To test these hypotheses empirically, we use a cross-section of around 405,000 firms from 35 European countries and 127 NACE three-digit industries. In line with previous research, we find that a firm's debt ratio increases with the corporate tax rate. Further, we observe that older firms exhibit smaller debt ratios than their younger counterparts. Finally, consistent with our theoretical model, we find a positive interaction between corporate taxation and firm age, indicating that the impact of corporate taxation on debt increases over a firm's lifetime.     

Interest rate changes and the timing of debt issues

There is much recent interest in the role of market timing in firm financial decisions. Using a large detailed sample of corporate public debt issues, private placements, Rule 144A issues and bank loans over the period 1970–2006, we investigate the relationship between interest rate changes and issues of floating and fixed-rate debt. Our results indicate that both past and future rates are associated with issuance decisions. We examine whether firms are able to lower their cost of capital by anticipating future rate changes, controlling for firm characteristics and market conditions. Our findings suggest that evidence of timing success is dependent on the time interval and type of debt examined. Over the longest time intervals available in our data, we do not find evidence of timing ability for fixed-rate or floating-rate debt issues.     

减税政策对小微企业债务期限结构的影响

本文主要探讨减税政策对小微企业债务期限结构的影响。理论上,减税政策对企业债务期限结构产生两种方向相反的效果:一是减税后企业盈利状况改善,激励银行通过延长债务期限以争取企业客户;二是减税后企业可支配现金流增加,加剧银行与企业间的委托代理问题,促使银行缩短债务期限以便加强企业监督。本文以所得税减半征收政策作为自然实验,基于全国税收调查数据库(2010-2015)考察了减税政策对小微企业债务期限结构的影响。实证结果显示:减税后企业的债务期限整体得以延长;如果减税后企业的盈利状况改善更多,或可支配现金流增长更缓,企业债务期限延长幅度更大。此外,本文发现在快速扩张行业、有产能过剩风险行业以及房地产上下游关联行业中的企业往往会因为较强的代理成本效应而面临减税后债务期限的边际缩短。本文研究结论对改善企业融资结构,特别对提高小微企业获取中长期贷款能力,有一定的参考意义。     

On the value and determinants of the interest tax shields

We use a dynamic model of the firm to ascertain both the value and the determinants of the debt tax shields. For a representative U.S. firm, we find that the value of the interest tax shields represents less than 5 % of firm value, and it varies considerably across U.S. industries. Our results also show that this component of firm value behaves counter-cyclically over the business cycle. Finally, besides the interest rate on debt and the corporate income tax rate, we find that the curvature of the production function is one of the main determinants of the tax advantage of debt.     

TOWARD A MORE COMPLETE MODEL OF OPTIMAL CAPITAL STRUCTURE

Most corporate finance practitioners understand the trade-off involved in making effective use of debt capacity while safeguarding the firm's ability to execute its business strategy without disruption. But quantifying that trade-off to arrive at an optimal level of debt can be a complicated and challenging task. This paper develops a simulation model of capital structure that starts by generating multiple estimates of market rates (LIBOR, currency rates) and corresponding company operating cash flows. To arrive at an optimal capital structure, the model then incorporates the shareholder value effects of alternative financing decisions by directly measuring the costs of financial distress, including the costs of missed investment opportunities and higher working capital requirements.
The model generates both a target credit rating and a lower fallback rating that permits a higher level of debt to maintain investments and dividends when operating cash flows are weak. As the model shows, companies with volatile cash flows and significant investment opportunities can add substantial shareholder value by establishing a fallback credit rating that is one or two notches below the target rating. The model also optimizes the mix of fixed versus floating debt, the maturity structure, and the currency composition. Another distinctive feature of the model is its ability to estimate the expected cost of alternative liability structures that can provide the liquidity insurance necessary to sustain the firm through periods of severe stress. This cost turns out to be quite small relative to the total market capitalization of the average firm.     

债务结构优化与企业创新——基于企业债券融资视角的研究

本文在我国保持宏观杠杆率基本稳定及实施创新驱动发展战略的现实背景下,从债券融资的视角,探讨债务结构优化对企业创新的影响。研究发现,债券融资与企业创新之间显著正相关,表明债券融资优化企业债务结构、提升企业创新能力的积极作用占据主导地位。进一步研究表明:(1)债券融资能够通过降低整体债务融资成本并延长整体债务期限促进企业创新;(2)债券融资对于银行贷款存在溢出效应,即企业通过债券融资,还能降低银行贷款利率、延长银行贷款期限,进而促进企业创新;(3)产品市场竞争和代理问题会在一定程度上削弱债券融资对企业创新的促进作用;(4)不同类型的债券对企业创新能力的作用存在异质性,债券发行的便利性是其影响企业创新的一个重要因素。     

Short‐Term Corporate Debt around the World

Short‐term corporate debt as a proportion of total debt issued by public firms varies greatly across countries, between 28% in the United States and 78% in China. This paper argues that the interaction between information asymmetry and legal protection of creditors is an important determinant of debt maturity. When short‐term debt plays a dual role as signaling and commitment devices, a reduction in information asymmetry has a larger impact on debt maturity when creditor rights are weaker. We find empirical support for this prediction using firm‐level data from 45 countries around the world.     

续贷限制与企业技术创新

本文以2007年的银行续贷政策改革作为“准自然实验”,采用双重差分模型探讨了续贷限制对企业技术创新的影响。研究发现,续贷限制显著抑制了企业的技术创新,且经过一系列稳健性检验后,该结论依然成立。进一步研究发现,该政策的作用效果因专利类型的不同而存在较大差异,具体表现为,在续贷限制之后,相较于低质量非发明专利,企业高质量发明专利下降幅度更大,进而企业创新质量降低。作用机制检验发现,续贷限制会降低企业信贷规模、缩短企业信贷期限以及增加企业融资成本,进而抑制企业技术创新。上述结果表明,“一刀切”式地收紧续贷标准会强化企业的融资约束,限制信贷资金对企业技术创新的支持作用,最终不利于企业的转型升级。本文研究为当前的续贷政策提供了来自企业创新视角的理论依据和实践参考。     

The Impact of Antitakeover Amendments on Corporate Financial Performance

Previous event studies that examine the impact of antitakeover amendments on firm value provide mixed results. Some studies support the management entrenchment hypothesis, while others support the shareholder interest hypothesis. In this study, a longitudinal approach is used to examine the impact of antitakeover amendments on several financial attributes of the firm including: operating and net income to total assets, operating and overhead expenses to sales, research and development to total sales, capital expenditures to sales, and debt relative to total assets. It is concluded that antitakeover amendments are not deleterious in terms of their impact on various fundamental firm performance measures.     

Corporate Behavior in Adjusting to Capital Structure and Dividend Targets: An Econometric Study

This study of financing decisions by U.S. corporations examines the issuance of long term debt, issuance of short term debt, maintenance of corporate liquidity, issuance of new equity, and payment of dividends. Given costs and imperfections inherent in markets, a firm's financial behavior is characterized as partial adjustment to long run financial targets. Individual firm data are used so that speeds of adjustment are allowed to vary by company and over time. The results suggest that financial decisions are interdependent and that firm size, interest rate conditions, and stock price levels affect speeds of adjustment.     

Federal financial guarantees and the occasional market pricing of default risk: Evidence from insured deposits

This paper develops a two-date state preference model which demonstrates that investors' valuation of third-party guaranteed debt depends on the financial condition of the guarantor. As the solvency ratio of the guarantor declines, investors demand higher promised rates on the firm's debt securities and price the firm risk variables more sensitively.The empirical results are derived from sample data of FSLIC guaranteed obligations from the late 1980s. Evidence shows differences in the market's perception of FSLlC's insolvency between 1987 and 1988. The market response to a decline in the financial condition of the guarantor affected the value of insured CDs, raising CD rates in relation to the Treasury curve and firm risk pricing of insured deposits emerged.     

股权结构 代理成本与外部审计需求

本文基于一个两时点大股东掠夺模型,考察了股权结构、代理成本与外部审计需求之间的关系。我们的模型分析结果表明,第一大股东持股比例与企业价值成U型曲线关系,而与外部审计需求成倒U型曲线关系。即:代理成本较高的上市公司更有可能聘请高质量的外部审计师,以降低代理成本,提高公司市场价值。我们以中国A股上市公司2001和2002年的数据,对上述结论进行了实证检验并得到支持,本文分析还表明,债务融资与外部审计在降低代理成本方面具有相互替代性。     

公开市场操作与利率期限结构行为——基于混频数据信息的研究视角

在混频数据信息环境中,精准识别公开市场操作(央行政策利率)和国债收益率曲线(基准利率体系)之间的关联机制至关重要,其影响了货币政策期限结构传导的有效性。本文在混频Nelson-Siegel(N-S)利率期限结构模型框架下,引入央行政策利率,揭示公开市场操作与利率期限结构(水平、斜率、曲度)因子之间的作用机制。实证结果表明:混频数据信息条件下,引入的公开市场操作信息显著改进国债收益率曲线的拟合效果;斜率因子冲击对公开市场操作具有显著的正向影响,而利率期限结构因子对政策调控的反应不敏感。进一步研究表明,2015年以来,公开市场操作对斜率因子的影响逐渐扩大,政策利率向国债收益率曲线的传导效率得到显著提高,我国现代货币政策框架日益健全。
