Measuring Investment – (Returns
Measurement)
First Principles
Ø
Invest in projects that
yield a return greater than the minimum acceptable hurdle rate.
Ø
The hurdle rate should be
higher for riskier projects and reflect the financing mix used - owners’ funds (equity)
or borrowed money (debt)
Ø Returns on projects
should be measured based on cash flows generated and the timing of these cash
flows; they should also consider both positive and negative side effects of
these projects.
Ø
Choose a financing mix that
minimizes the hurdle rate and matches the assets being financed.
Ø
If there are not enough
investments that earn the hurdle rate, return the cash to stockholders.
Ø
The form of returns -
dividends and stock buybacks - will depend upon the stockholders’ characteristics.
Measures of return: earnings versus cash flows
Ø
Principles Governing
Accounting Earnings Measurement
1.
Accrual Accounting: Show revenues
when products and services are sold or provided, not when they are paid for.
Show expenses associated with these revenues rather than cash expenses.
2.
Operating versus Capital
Expenditures: Only expenses associated with creating revenues in the current
period should be treated as operating expenses. Expenses that create benefits
over several periods are written off over multiple periods (as depreciation or
amortization)
Ø
To get from accounting
earnings to cash flows:
1.
you have to add back non-cash
expenses (like depreciation)
2.
you have to subtract out cash
outflows which are not expensed (such as capital expenditures)
3.
You have to make accrual revenues
and expenses into cash revenues and expenses (by considering changes in working
capital).
Measuring Returns Right: The Basic Principles
Ø
Use cash flows rather than
earnings. You cannot spend earnings.
Ø
Use “incremental” cash flows
relating to the investment decision, i.e., cashflows that occur as a
consequence of the decision, rather than total cash flows.
Ø
Use “time weighted”
returns, i.e., value cash flows that occur earlier more than cash flows that
occur later.
Application Test: Assessing Investment Quality
Ø
For the most recent period
for which you have data, compute the aftertax return on capital earned by your
firm, where after-tax return on capital is computed to be
After-tax ROC = EBIT (1-tax
rate)/ (BV of debt + BV of Equity) previous year
Ø
For the most recent period
for which you have data, compute the return spread earned by your firm:
Return Spread = After-tax ROC -
Cost of Capital
Ø
For the most recent period,
compute the EVA earned by your firm
EVA = Return Spread * ((BV of
debt + BV of Equity) previous year
The Depreciation Tax Benefit
Ø
While depreciation reduces
taxable income and taxes, it does not reduce the cash flows.
Ø
The benefit of depreciation
is therefore the tax benefit. In general, the tax benefit from depreciation can
be written as:
Tax Benefit = Depreciation * Tax
Rate
Ø
Proposition 1: The
tax benefit from depreciation and other non-cash charges is greater, the higher
your tax rate.
Ø
Proposition 2:
Non-cash charges that are not tax deductible (such as amortization of goodwill)
and thus provide no tax benefits have no effect on cash flows.
Depreciation Methods
Broadly categorizing,
depreciation methods can be classified as straight line or accelerated methods.
In straight line depreciation, the capital expense is spread evenly over time, in
accelerated depreciation; the capital expense is depreciated more in earlier
years and less in later years.
The Capital Expenditures Effect
Ø
Capital expenditures are
not treated as accounting expenses but they do cause cash outflows. Capital
expenditures can generally be categorized into two groups
1.
New (or Growth) capital
expenditures are capital expenditures designed to create new assets and future
growth
2.
Maintenance capital expenditures
refer to capital expenditures designed to keep existing assets.
Ø
Both initial and
maintenance capital expenditures reduce cash flows. The need for maintenance
capital expenditures will increase with the life of the project. In other
words, a 25-year project will require more maintenance capital expenditures
than a 2-year asset
