Question: Which method is preferred?
Answer: It depends, on the MARR%, i% used by the firm (individual)


As an example:
If i% is=
0%
2%
10%
25%

PW of DDB is=
$925,000
$881,211
$738,331
$561,631

PW of SOYD is=
$925,000
$877,801
$724,468
$537,130

Preferred is
Equal, same
DDB
DDB
DDB

Thus, if MARR% is > 0%, DDB is best. One can also see this by inspection of the
depreciation schedules above.

By looking at the data in Part (a), some students may jump to the conclusion that
one should switch from DDB to Straight Line depreciation at the beginning of Year 3.
This mistaken view is based on the fact that in the table above the Straight Line
depreciation for Year 3 is $15,2000, while the DDB depreciation is only $10,944.
This is not a correct analysis of the situation.
This may be illustrated by computing the Straight Line depreciation for Year 3, if DDB
depreciation had been used in the prior years.
With DDB depreciation for the first two years, the book value at the beginning of Year
3 = $76,000 - $30,400 - $18,240 = $27,360.
SL depreciation for subsequent years = ($27,360 - $0)/3 = $9,120.
Thus, the choice for Year 3 is to use DDB = $10,944 or SL = $9,120. One would
naturally choose to continue with DDB depreciation.
For subsequent years:

place at the beginning of Year 4. The resulting depreciation schedule is:

EUACII = ($100,000 - $25,000) (A/P, 10%, 25) + $25,000 (0.10) + $20,000
- $5,000 (P/A, 10%, 10) (A/P, 10%, 25)
= $75,000 (0.1102) + $2,500 + $20,000 - $5,000 (6.145) (0.1102)
= $27,380


To minimize EUAC, select Machine II.
(b) Capitalized Cost of Machine I= PW of an infinite life = EUAC/i
In part (a), EUAC = $27,050, so:
Capitalized Cost
= $27,050/0.10
= $270,500
(c) Fund to replace Machine I
Required future sum F
Annual Deposit

= $80,000 - $20,000 = $60,000
A
= $60,000 (A/P, 10%, 20)

= ($28,000 - $18,000) (P/A, i%, 20) + $20,000 (P/F, i%, 20)

Solve by trial and error:
Try i = 10%
($10,000) (8.514) + $20,000 (0.1486)

= $88,112

≠ $80,000

Try i = 12%
($10,000) (7.469) + $20,000 (0.1037)

= $76,764

≠ $80,000

Rate of Return = 10% + (2%) [($88,112 - $80,000)/($88,112 - $76,764)]
= 11.4%
(e) SOYD depreciation
Book value of Machine I after two periods
Dep. Charge in any year = (Remain. useful life at beginning of yr/SOYD
for total useful life)(P – S)
Sum of years digits

= (n/2) (n + 1) = 20/2 (20 + 1) = 210

1st Year depreciation = (20/210) ($80,000 - $20,000)
2nd Year depreciation = (19/210) ($80,000 - $20,000)
Book value

= Cost – depreciation to date
= $80,000 - $11,143
= $68,857

(f) DDB Depreciation
Book value of Machine II after three years

= $5,714
= $5,429
Sum = $11,143


Depreciation charge in any year
= (2/n) (P – Depreciation charge to date)
1st Year Depreciation = (2/25) ($100,000 - $0)
= $8,000
2nd Year Depreciation = (2/25) ($100,000 - $8,000) = $7,360
3rd Year Depreciation = (2/25) ($100,000 - $15,360)
= $6,771
Sum = $22,131
Book Value

= Cost – Depreciation to date
= $100,000 - $22,131

Taxable Income inc. depletion

Percentage depletion = 5% ($29,250) = $1,462.50
Therefore, allowable depletion is $1,462.50.

Percentage depletion
