The Financing Mix

11/08/05

The financing mix question

In deciding to raise financing for a business, is there an optimal mix of debt and equity? If yes, what is the trade off that lets us

determine this optimal mix? If not, why not?

Costs and benefits of debt

Benefits of Debt Tax Benefits Adds discipline to management

Costs of Debt Bankruptcy Costs Agency Costs Loss of Future Flexibility

Tax benefits of debt

Interest paid on debt is tax deductible, whereas cash flows to equity have to be paid out of after-tax cash flows.

The dollar tax benefit from the interest payment in any year is a function of your tax rate and the interest payment:

Tax benefit each year = Tax Rate * Interest Payment

The effects of taxes

You are comparing the debt ratios of real estate corporations,

which pay the corporate tax rate, and real estate investment

trusts, which are not taxed, but are required to pay 95% of their

earnings as dividends to their stockholders. Which of these two

groups would you expect to have the higher debt ratios?

The real estate corporations

The real estate investment trusts

Cannot tell, without more information

Implications of the tax benefit of debt The debt ratios of firms with higher tax rates should be higher

than the debt ratios of comparable firms with lower tax rates.

Firms that have substantial non-debt tax shields, such as depreciation, should be less likely to use debt than firms that do not have these tax shields.

If tax rates increase over time, we would expect debt ratios to go up over time as well, reflecting the higher tax benefits of debt.

We would expect debt ratios in countries where debt has a much larger tax benefit to be higher than debt ratios in countries whose debt has a lower tax benefit.

Debt adds discipline to management Free cash flow represents cash flow from operations after all

obligations have been paid.

It represents cash flow for which management has discretionary spending power.

Without discipline, management may make wasteful investments with free cash flow because they do not bear any costs for making these investments.

Forcing firms with free cash flow to borrow money can be an antidote to managerial complacency.

Empirical evidence is consistent with the hypothesis that increasing debt improves firm performance.

Debt and discipline

Assume that you buy into this argument that debt adds discipline to

management. Which of the following types of companies will

most benefit from debt adding this discipline?

Conservatively financed (very little debt), privately owned

businesses

Conservatively financed, publicly traded companies, with stocks

held by millions of investors, none of whom hold a large percent

of the stock.

Conservatively financed, publicly traded companies, with an

activist and primarily institutional holding.

Bankruptcy cost

Bankruptcy is when a firm is unable to meet its contractual commitments.

The expected bankruptcy cost is a function of two variables-- the cost of going bankrupt

direct costs: Legal and other administrative costs (1-5% of asset value)

indirect costs: Costs arising because people perceive you to be in financial trouble – loss of revenue, stricter supplier terms, capital raising difficulties

the probability of bankruptcy, which is a function of the size of operating cash flows relative to debt obligations and the variance in operating cash flows

As you borrow more, you increase the probability of bankruptcy and hence the expected bankruptcy cost.

Indirect bankruptcy costs should be highest for…. Firms that sell durable products with long lives that require

replacement parts and service

Firms that provide goods or services for which quality is an important attribute but where quality difficult to determine in advance

Firms producing products whose value to customers depends on the services and complementary products supplied by independent companies

Firms that sell products requiring continuous service and support from the manufacturer

The bankruptcy cost proposition and implications Proposition:

Other things being equal, the greater the indirect bankruptcy cost and/or probability of bankruptcy in the operating cash flows of the firm, the less debt the firm can afford to use.

Implications: Firms operating in businesses with volatile earnings

and cash flows should use debt less than otherwise similar firms with stable cash flows.

Firms with assets that can be easily divided and sold should borrow more than firms with assets that are less liquid.

Agency cost (conflict between stockholder and bondholder) When you lend money to a business, you are

allowing the stockholders to use that money in the course of running that business. Stockholders interests are different from your interests, because You (as lender) are interested in getting your

money back Stockholders are interested in maximizing

their wealth

Agency cost (conflict between stockholder and bondholder) In some cases, the clash of interests can lead

to stockholders Investing in riskier projects than you would

want them to Paying themselves large dividends when you

would rather have them keep the cash in the business.

Agency cost proposition

Other things being equal, the greater the agency problems associated with lending to a firm, the less debt the firm can afford to use.

What firms are most affected by agency cost? Agency costs will tend to be the greatest in firms whose

investments cannot be easily monitored or observed

Agency costs will tend to be the greatest for firms whose projects are long-term, unpredictable or will take years to come to fruition.

How agency costs show up...

If bondholders believe there is a significant chance that stockholder actions might make them worse off, they can build this expectation into bond prices by demanding much higher rates on debt.

If bondholders can protect themselves against such actions by writing in restrictive covenants, two costs follow –

the direct cost of monitoring the covenants

the indirect cost of lost investments

Loss of future financing flexibility

When a firm borrows up to its capacity, it loses the flexibility of financing future projects with debt.

Financing Flexibility Proposition: Other things remaining equal, the more

uncertain a firm is about its future financing requirements and projects, the less debt the firm will use for financing current projects.

What managers consider important in

deciding on how much debt to carry... A survey of Chief Financial Officers of large U.S. companies

provided the following ranking (from most important to least important) for the factors that they considered important in the financing decisions

Factor Ranking (0-5)

2. Ensure long-term survival 4.55

3. Maintain Predictable Source of Funds 4.05

Debt: Summarizing the Trade Off

Advantages of Borrowing Disadvantages of Borrowing

1. Tax Benefit:

Higher tax rates --> Higher tax benefit

1. Bankruptcy Cost:

Higher business risk --> Higher Cost

2. Added Discipline:

Greater the separation between managers

and stockholders --> Greater the benefit

2. Agency Cost:

Greater the separation between stock-

holders & lenders --> Higher Cost

3. Loss of Future Financing Flexibility:

Greater the uncertainty about future

financing needs --> Higher Cost

A qualitative analysis of the firm’s debt ratio Tax benefits:

What is the firm’s tax rate? Does the company have substantial tax shields?

Discipline: Does management own shares? Does the firm have significant free cash flows?

Bankruptcy: How volatile are the firm’s earnings and cash flows? How liquid and divisible are the firm’s assets?

Agency: Are the firm’s investments easily monitored? Are the investments short term or long term?

Financial Flexibility: What stage of life cycle is the firm in?

A Qualitative Analysis

Item Boeing The Home Depot InfoSoft Tax Benefits Significant. The firm has a

marginal tax rate of 35%. It does have large depreciation tax shields.

Significant. The firm has a marginal tax rate of 35%, as well. It does not have very much in non-interest tax shields.

Significant. The owners of InfoSoft face a 42% tax rate. By borrowing money, the income that flows through to the investor can be reduced.

Added Discipline Benefits will be high, since managers are not large stockholders.

Benefits are smaller, since the CEO is a founder and large stockholder.

Benefits are non-existent. This is a private firm.

Bankruptcy Cost Direct costs are likely to be small, but indirect costs can be substantial..

Direct costs are likely to be small. Assets are mostly real estate. Indirect costs will also be small.

Costs may be small but the owner has all of his wealth invested in the firm.

Agency Costs Low. Assets are generally tangible and monitoring should be feasible.

Low. Assets are stores and real estate, tangible and marketable.

High. Assets are intangible and difficult to both monitor and to liquidate.

Flexibility Needs Low. Firm has a long gestation period for projects, and knows how much it needs to invest in advance.

Low in existing business, but high, given its plans to grow overseas and online. Expansion and acquisition needs create need.

High. Firm might have to change its product and business mix, on short notice, as technology changes

The Miller-Modigliani Theorem

Assume you operate in an environment, where there are no taxes there is no separation between stockholders

and managers. there is no default risk there is no separation between stockholders

and bondholders firms know their future financing needs

The Miller-Modigliani Theorem

Then, The value of a firm is independent of its debt

ratio

Implications: Leverage is irrelevant. A firm's value will be

determined by its project cash flows. The cost of capital of the firm will not change

with leverage. As a firm increases its leverage, the cost of equity will increase just enough to offset any gains to the leverage

The Miller-Modigliani Theorem with taxes When taxes are introduced, with no costs to debt, the

optimal debt level for a firm is 100%.

Value of firm with perpetual debt (B) and a tax rate of t:

Value = Value of all-equity (unlevered) firm + tB

where tB is the present value of tax savings from debt

Can debt be irrelevant in a world with taxes? In the presence of personal taxes on both interest

income and income from equity, it can be argued that debt could still be irrelevant if the cumulative taxes paid (by the firm and investors) on debt and equity are the same.

Thus, if td is the personal tax rate on interest income received by investors, te is the personal tax rate on income on equity and tc is the corporate tax rate, debt will be irrelevant if:

(1 - td) = (1-tc) (1-te)

Is there an optimal capital structure? When marginal benefits and costs of taking

on debt are considered, an optimal capital structure exists where these two are equal.

The empirical evidence on whether leverage affects value is mixed.

How do firms set their financing mixes? Life Cycle: Some firms choose a financing mix that reflects

where they are in the life cycle; start- up firms use more equity, and mature firms use more debt.

Comparable firms: Many firms seem to choose a debt ratio that is similar to that used by comparable firms in the same business.

Financing Heirarchy: Firms also seem to have strong preferences on the type of financing used, with retained earnings being the most preferred choice. They seem to work down the preference list, rather than picking a financing mix directly.

Comparable firms

When we look at the determinants of the debt ratios of individual firms, the strongest determinant is the average debt ratio of the industries to which these firms belong.

This is not inconsistent with the existence of an optimal capital structure. If firms within a business share common characteristics (high tax rates, volatile earnings etc.), you would expect them to have similar financing mixes.

Rationale for financing hierarchy

Managers value flexibility. External financing reduces flexibility more than internal financing.

Managers value control. Issuing new equity weakens control and new debt creates bond covenants.
