Depreciation and Income Taxes Chapter 9 Advanced Engineering Economy

Depreciation Definition: Loss of value for a fixed asset Example: You purchased a car worth $15,000 at the beginning of year 2000. Depreciation End of Year Market Value Loss of Value 012345012345 $15,000 10,000 8,000 6,000 5,000 4,000 $5,000 2,000 1,000
3
Why Do We Consider Depreciation? Gross Income -Expenses: (Cost of goods sold) (Depreciation) (operating expenses) Taxable Income - Income taxes Net income (profit) Business Expense: Depreciation is viewed as part of business expenses that reduce taxable income.
4
Factors to Consider in Asset Depreciation Depreciable life (how long?) Salvage value (disposal value) Cost basis (depreciation basis) Method of depreciation (how?)
5
What Can Be Depreciated? Assets used in business or held for production of income Assets having a definite useful life and a life longer than one year Assets that must wear out, become obsolete or lose value A qualifying asset for depreciation must satisfy all of the three conditions above.

7
Useful Life and Salvage Value Useful life – Adopt the Asset Depreciation Ranges (ADR) published by the IRS. Salvage value – Asset’s estimated value at the end of its useful life. Every effort should be made to estimate a reasonable residual value of the asset, but if not possible, a 10% rule (10% of the initial value) could be adopted for depreciation purpose.
8
Types of Depreciation Book Depreciation –In reporting net income to Investors/stockholders –In pricing decision Tax Depreciation –In calculating income taxes for the IRS –In engineering economics, we use depreciation in the context of tax depreciation
9
Book versus Tax Depreciation – An Overview Component of Depreciation Book DepreciationTax depreciation (MACRS) Cost basis Based on the actual cost of the asset, plus all incidental costs such as freight, site preparation, installation, etc. Same as for book depreciation Salvage value Estimated at the outset of depreciation analysis. If the final book value does not equal the estimated salvage value, we may need to make adjustments in our depreciation calculations. Salvage value is zero for all depreciable assets
10
Component of Depreciation Book DepreciationTax depreciation (MACRS) Depreciable life Firms may select their own estimated useful lives or follow government guidelines for asset depreciation ranges (ADRs) Eight recovery periods– 3,5,7,10,15,20,27.5,or 39 years– have been established; all depreciable assets fall into one of these eight categories. Method of depreciation Firms may select from the following: Straight-line Accelerated methods (declining balance, double declining balance, and sum-of- years’ digits) Units-of-proportion Exact depreciation percentages are mandated by tax legislation but are based largely on DDB and straight-line methods. The SOYD method is rarely used in the U.S. except for some cost analysis in engineering valuation.
11
Book Depreciation Methods Purpose: Used to report net income to stockholders/investors Types of Depreciation Methods: –Straight-Line (SL) Method –Declining Balance Method –Unit Production Method
12
Straight – Line (SL) Method Principle A fixed asset as providing its service in a uniform fashion over its life Formula Annual Depreciation D n = (I – S) / N, and constant for all n. Book Value B n = I – n (D) where I = cost basis S = Salvage value n = depreciable life
13
Example: Straight-Line Method D1 D2 D3 D4 D5 B1 B2 B3 B4 B5 $10,000 $8,000 $6,000 $4,000 $2,000 0 1 2 3 4 5 Total depreciation at end of life nD n B n 0 10,000 11,6008,400 21,6006,800 31,6005,200 41,6003,600 51,6002,000 I = $10,000 N = 5 Years S = $2,000 D = (I - S)/N Annual Depreciation Book Value n
14
Declining Balance Method Principle: A fixed asset as providing its service in a decreasing fashion Formula Annual Depreciation Book Value where 0 < < 2(1/N) Note: if is chosen to be the upper bound, = 2(1/N), we call it a 200% DDB or Double Declining Balance method.
15
Example: Declining Balance Method D1 D2 D3 D4 B1 B2 B3 B4 B5 $10,000 $8,000 $6,000 $4,000 $2,000 0 1 2 3 4 5 Total depreciation at end of life $778 Annual Depreciation Book Value n012345n012345 D n $4,000 2,400 1,440 160 0 B n $10,000 6,000 3,600 2,160 2000 n ά =2(1/N) =2(1/5) =40%

Example: DB Switching to SL SL Dep. Rate = 1/5 (DDB rate) = (200%) (SL rate) = 0.40 Asset:Invoice Price $9,000 Freight 500 Installation 500 Depreciation Base$10,000 Salvage Value 0 Depreciation200% DB Depreciable life5 years

Case 1: S = 0
18
Case 2: S = $2,000 End of YearDepreciationBook Value 10.4($10,000) = $4,000$10,000 - $4,000 = $6,000 20.4(6,000) = 2,4006,000 – 2,400 = 3,600 30.4(3,600) = 1,4403,600 –1,440 = 2,160 40.4(2,160) = 864 > 1602,160 – 160 = 2,000 502,000 – 0 = 2,000 Note: Tax law does not permit us to depreciate assets below their salvage values.
19
Units-of-Production Method Principle Service units will be consumed in a non time-phased fashion Formula Annual Depreciation D n = Service units consumed for year total service units (I - S)
20
Example Given: I = $55,000, S = $5,000, Total service units = 250,000 miles, usage for this year = 30,000 miles Solution:

Purpose: Used to compute income taxes for the IRS Assets placed in service prior to 1981 Use book depreciation methods (SL, DB) Assets placed in service from 1981 to 1986 Use Accelerated Cost Recovery System (ACRS) Table Assets placed in service after 1986 Use Modified Accelerated Cost Recovery System MACRS Table

Net Income Versus Cash Flow

34
Cash Flow vs. Net Income Net income : Net income is an accounting means of measuring a firm’s profitability based on the matching concept. Costs become expenses as they are matched against revenue. The actual timing of cash inflows and outflows are ignored. Cash flow : Given the time value of money, it is better to receive cash now than later, because cash can be invested to earn more money. So, it is desirable why cash flows are relevant data to use in project evaluation.
35
Why Do We Use Cash Flow in Project Evaluation? Company ACompany B Year 1Net income Cash flow $1,000,000 1,000,000 $1,000,000 0 Year 2Net income Cash flow 1,000,000 2,000,000 Example: Both companies (A & B) have the same amount of net income and cash sum over 2 years, but Company A returns $1 million cash yearly, while Company B returns $2 million at the end of 2 nd year. Company A can invest $1 million in year 1, while Company B has nothing to invest during the same period.

Disposal of Depreciable Asset If a MACRS asset is disposed of during the recovery period, Personal property: the half-year convention is applied to depreciation amount for the year of disposal. Real property: the mid-month convention is applied to the month of disposal.
46
Disposal of a MACRS Property and Its Effect on Depreciation Allowances
47
Case 1: Salvage Value < Cost Basis Gains (losses) = Salvage value – book value These gains, commonly known as either ordinary gains or depreciation recapture, are taxed as ordinary income. Most gains experienced in manufacturing environment refer to these ordinary gains. Any losses (ordinary) can be deducted from the ordinary gains from other assets first and any remaining balance can be deducted from the ordinary taxable income.
48
Case 2: Salvage Value > Cost Basis Gains = Salvage value – book value = (Salvage value - cost basis) Capital gains + (Cost basis – book value) Ordinary gains Capital gain is taxed as ordinary income under current tax law.
49
Gains or Losses on Depreciable Asset Example: A Drill press: $230,000 Project year: 3 years MACRS:7-year property class Salvage value:$150,000 at the end of Year 3 14.2924.4917.4912.498.92 Full Half Total Dep. = 230,000(0.1429 + 0.2449 + 0.1749/2) = $109,308 Book Value = 230,000 -109,308 = $120,693 Gains = Salvage Value - Book Value = $150,000 - $120,693 = $29,308 Gains Tax (34%) = 0.34 ($29,308) = $9,965 Net Proceeds from sale = $150,000 - $9,965 = $140,035
