When Projects Require Working-Capital
Investments
Working Capital Equations
What is Working Capital?


Working capital means the
amount carried in cash,
accounts receivable, and
inventory that is available to
meet day-to-day operating
needs.
How to treat working capital
investments: just like a capital
expenditure except that no
depreciation is allowed.
 Accounting definition:
 WC = Current Asset – Current Liabilities
 WC = CA - CL
 where WC = changes in working
capital
 CA = changes in current assets
 CL = changes in current liabilities
 If WC > 0, working capital requirement. With
the net change being positive, the firm has a
net requirement of working capital that has to
be financed during the year. Therefore, the
WC requirement appears as uses of cash in
the cash flow statement.
 If WC < 0, working capital release. If this
amount were negative, there would have
been a cash inflow from working capital
release, which could add to the sources of
cash.

When Projects Results in Negative Taxable Income

Negative taxable
income (project
loss) means you
can reduce your
taxable income
from regular
business operation
by the amount of
loss, which results
in tax savings.

Cash Flow Statement (Table 10.7)

When Projects are Financed with Borrowed
Funds
 Key issue: Interest
payment is a taxdeductible expense.
 What Needs to Be Done:
Once a loan repayment
schedule is known,
separate the interest
payments from the
annual installments.
 What about Principal
Payments? As the
amount of borrowing is
NOT viewed as income to
the borrower, the
repayments of principal
are NOT viewed as
expenses either – NO tax
effect.

Loan Repayment Schedule (Example 10.4)
Amount financed: $62,500, or 50% of total capital expenditure
Financing rate: 10% per year
Annual installment: $16,487 or, A = $62,500(A/P, 10%, 5)

Example 10.4 -Cash Flow Statement with Debt
Financing
 Effects of Debt Financing
on Profitability
MARR = 15%, debt interest rate =
10%
 NPW without debt financing
(100% equity)
PW(15%) = $31,420
 NPW with debt financing (50%
debt)
PW(15%) = $44,439
The debt financing increases the
present worth by $13,019. This
result is largely caused by the firm’s
being able to borrow the funds at a
cheaper rate (10%) than its MARR of
15%.
