After-Tax Cash Flows

12-2EECE 450 — Engineering Economics

Chapter 12 …Shows how to calculate income taxes.Discusses incremental income taxes.Determines combined federal and

provincial income tax rates.Calculates after-tax cash flows.Determines after-tax performance

measures, e.g. NPV, EACF, IRR, NFV, PBP, and BCR.

Evaluates projects on an after-tax basis with acquisition & disposal of assets.


Income Taxes Taxes have an effect on cash flows and on

the investment decisions managers make. Integrating tax considerations into economic

analysis requires a thorough understanding of two issues:• how the taxes are imposed; and• how taxes affect economic analysis techniques.


Income Taxes … Federal income taxes are determined from

taxable income and income tax rates.• Progressive individual federal income tax structure

Gross Income – Deductions = Taxable income.• Gross income: wages, salary, interest income,

dividend income, etc.• Deductions: retirement plan contributions,

business investment expenses, etc.

Personal income tax rates vary across provinces and are progressive; the exception is Alberta which uses a flat rate.


Income Taxes … Average tax rate = Taxes payable/taxable

income. Marginal tax rate— the tax rate that applies to

the next dollar of income earned. If the next dollar of income does not cause

the tax to advance to the next level, i.e. “bracket creep”, the marginal tax rate equals the sum of the federal income tax rate + provincial income tax rate.• An individual at the 26% federal tax level and the

12.29% provincial tax level has a marginal tax rate of 38.29% (about $85,000 taxable income in B.C.).


Corporate Income Taxes More complex than individual income taxes.

• Accountants apply Generally Accepted Accounting Principles (GAAP).

The Income Tax Act defines specific accounting concepts: • Depreciation/amortization, cost base, book value,

salvage value.

Combined federal and provincial corporate tax rates for British Columbia in 2009 were:• 14.5% for small business income up to $400,000;• 30% for Canadian-controlled private corporations

(CCPCs) with income over $400,000.

Accounting & Engineering Economy Understand the tax laws affecting the project

of interest. Estimate the cash flows without considering

the effects of taxes. Adjust the cash flows based on the effects of

depreciation and income taxes. Determine the after-tax measure(s) of merit

(NPV, IRR, etc.).


Accounting & Eng’g Economy … Principal accounting statements:

• Balance sheet: financial position at end of year.• Income statement: earnings during one year.• Cash flow statement: sources and uses of cash.

Key amounts from the income statement:• Operating revenue = Operating cost + BTCF

(before-tax cash flow)• BTCF = Debt interest + CCA + Taxable income• Taxable income = BTCF Debt interest CCA• Taxable income = Net profit + Income tax• Net profit = Taxable income Income tax• Net profit = (Taxable income)(1 T)


Accounting & Eng’g Economy … After-tax cash flow (ATCF):

= Net profit + CCA + Debt interest (I)

= (Taxable income)(1T) + CCA + I

= (BTCF I CCA)(1 T) + CCA + I

= (OR OC)(1 T) + I(T) + CCA(T) Net cash flow from operations:

= ATCF – I – Dividends (DIV)

= (OR OC)(1T) + I(T) + CCA(T) I DIV

= (OR OC I)(1T) + CCA(T) DIV

= Net profit + CCA DIV


Accounting & Eng’g Economy … Net cash flow =

Net cash flow from operations

+ New equity issued

+ New debt issued

+ Proceeds from asset disposal

Repurchase of equity

Repayment of debt principal

Purchase of assets


Accounting & Eng’g Economy … The CCA (depreciation) expense reduces the

taxable income but it increases the cash flow. The CCA increases the cash flow by an

amount = TCCA, called the CCA tax shield.

The CCA is added to the net income to get the net after-tax cash flow.


Accounting & Eng’g Economy … Acquiring and disposing of assets:

• Acquisitions are added to an asset pool and disposals are subtracted from the asset pool.

• Reconciliation to the cash flow requires calculation of the net salvage value.

• From Canadian tax rules, an asset class remains open as long as there are assets remaining in it.

• If there is a loss on disposal or recaptured CCA: if the asset class remains open, the loss or recaptured

CCA is allocated on an ongoing basis by the declining balance method at the asset group’s CCA rate;

if the asset class must be closed because there are no assets remaining in it, the terminal loss or recaptured CCA is applied to the income.


Accounting & Eng’g Economy … A capital gain is realized when an asset is

sold for more than its original cost. 50% of the capital gain (selling price original

cost) is taxed at the marginal rate. Net salvage value (NSV):

• Asset class open: NSV = S.

• Asset class closed: NSV = S + T(BdS).

S = Salvage value (before-tax proceeds from disposal)

T = marginal tax rate

Bd = Book value at disposal (UCC)


CCA and Capital Costs When a capital asset is acquired, the present

value of the net capital investment is:

Use this formula only if it is valid to assume the full CCA will be taken every year.

Working Capital Requirements Time lags exist between dispensing cash for

expenses and receiving cash from sales. Working capital = injection of cash, or cash

equivalents, to cover these time lags. Most investments require an initial investment

in working capital. The working capital is recovered entirely at the end of the project.

There may be changes in the level of working capital required throughout the project.

Working capital does not gain value nor does it depreciate in value during the project.


After-tax Rate of Return It is usually a complex matter to obtain the

after-tax MARR and it cannot usually be obtained from the before-tax MARR, however MARRafter-tax MARRbefore-tax(1T) is a reasonable approximation.

We will assume, unless it is otherwise clearly stated, that we are using an after-tax MARR when we analyze the economics of a project.


Comprehensive Example Johnston Forwarding Inc. is considering the

purchase of twenty new trucks for a special purpose fleet in their freight division. Each truck costs $67,500. They are expected to be in service for eight years, then be salvaged for $5000 each. The trucks will be added to an existing CCA Class 10 asset pool. Each truck is expected to generate $20,750 in annual revenue, net of direct operating costs. Johnston’s maintenance cost centre charges $1550 per truck annually. (Continued …)


Comprehensive Example … There is also a fixed annual cost of $35,000

to cover management and administration of the twenty trucks in the proposed fleet. Each truck will require an immediate investment of $7500 in net working capital. Johnston uses a minimum acceptable rate of return of 14 percent to analyze investments of this type. Johnston’s marginal tax rate is 30 percent.

Determine whether Johnston Forwarding Inc. should invest in the new trucks. Use both a value and a rate of return criterion.


Comprehensive Example …Purchase cost per truck : $67,500Salvage value per truck : $5,000

Number of trucks: 20Annual net revenue per truck : $20,750

Annual maintenance charge per truck : $1,550Fixed costs: $35,000

Work ing capital per truck : $7,500CCA rate: 30%Tax rate: 30%

MARR: 14%Planned lifetime (years): 8

Truck purchase -$1,350,000.00PV(CCA tax shield gained) $259,180.62

Investment in work ing capital -$150,000.00PV(Salvage) $35,055.91

PV(CCA tax shield lost on salvage) -$7,170.53PV(recovered work ing capital) $52,583.86

PV(net after-tax operating cash flow) $1,133,274.45

NPV= -$27,075.69IRR= 13.471%

Johnston Forwarding Inc. should not invest in the trucks.


Suggested Problems 12-23 (NPV), 25 (PBP & IRR), 37 (PBP, NPV

& IRR), 38 (NPV & IRR), 39 (NPV & IRR), 50, 51.

At the time of disposal of an asset, unless it is otherwise explicitly stated, assume:• the CCA asset class continues (has other assets

remaining in it) and has greater value before the disposal than the value of the asset being salvaged;

• the asset disposal occurs at year-end, after the CCA has been taken for the final year.
