### Exercise 1

Determine the Recommended Maximum Index Factor for the following types of equipment based on the given economic life (service life), as of lien date 2011 (January 1).

Solution

**Solution:**

- Maximum Index Factor Age = Economic Life × 125%

*(15 × 125% = 19 years)*

Maximum Index Factor Year = Valuation Lien Date Year - Maximum Index Factor Age

*(2011 - 19 years = 1992)*

Recommended Index Factor corresponds to Maximum Index Factor Year

152 ⇔ 1992 (2011 AH 581 Table 1 - Commercial)

- Maximum Index Factor Age = Economic Life × 125%

*(8 × 125% = 10 years)*

Maximum Index Factor Year = Valuation Lien Date Year - Maximum Index Factor Age

(2011 - 10 years = 2001)

Recommended Index Factor corresponds to Maximum Index Factor Year

120 ⇔ 2001 (2011 AH 581 Table 2 - Industrial)

- Maximum Index Factor Age = Economic Life × 125%

(12 × 125% = 15 years)

Maximum Index Factor Year = Valuation Lien Date Year - Maximum Index Factor Age

(2011 - 15 years = 1996)

Recommended Index Factor corresponds to Maximum Index Factor Year

137 ⇔ 1996 (2011 AH 581 Table 3 - Construction)

- Maximum Index Factor Age = Economic Life × 125%

(6 × 125% = 8 years)

Maximum Index Factor Year = Valuation Lien Date Year - Maximum Index Factor Age

(2011 - 8 years = 2003)

Recommended Index Factor corresponds to Maximum Index Factor Year

128 ⇔ 2003 (2011 AH 581 Table 1 - Commercial)

### Exercise 2

In 1994, a company purchased light plant equipment for $100,000. If the economic life of light plant equipment (non-mobile construction equipment) is 12 years, what is the recommended maximum index factor for use in valuing this type of equipment, as of lien date 2011 (January 1); and what is its RCN?

Solution

**Solution:**

**Recommended Maximum Index Factor**

- Maximum Index Factor Age = Economic Life × 125% (converted to a decimal equivalent)
- Maximum Index Factor Age =
**15 years** (12 years × 1.25)

- Maximum Index Factor Year = Valuation Lien Date Year – Maximum Index Factor Age
- Maximum Index Factor Year =
**1996** (2011 – 15 years)

- Recommended Maximum Index Factor =
**137** (Table 3 index factor for 1996)

- Calculate the Maximum Index Factor Age* for the equipment by multiplying its economic life by 125 percent. (Economic life determined to be 12 years based on a review of the CAA tables, as discussed in Lesson 5.)

*12 years × 1.25 = 15 years* (rounded to the nearest whole number)*

- Calculate the Maximum Index Factor Year for the equipment by subtracting its Maximum Index Factor Age from its valuation lien date year.

*2011 - 15 years = 1996*

- Locate the Recommended Maximum Index Factor by finding the construction index factor corresponding to the Maximum Index Factor Year, using 2011 AH 581 Table 3:
*Agricultural and Construction Equipment Index Factors*.

*1996 = 137*

**RCN**

- Acquisition Year Index Factor =
**143** (Table 3 construction index factor for 1994)

- The lesser of the Recommended Maximum Index Factor and the Acquisition Year Index Factor =
**137** < 143

- RCN = Cost × Index Factor (converted to decimal equivalent)
- RCN = $100,000 × 1.37
- RCN = $137,000

- Determine the Acquisition Year Index Factor by finding the "construction" equipment index factor corresponding to the year that the equipment being valued was acquired (1994), using Table 3 of the January 2011 AH 581.

*1994 = 143*

- Select the lesser of the Recommended Maximum Index Factor and the Acquisition Year Index Factor for use in valuing the equipment.

*137 < 143*

- Calculate the RCN (2011) for the equipment, by multiplying the acquisition cost of the equipment by the decimal equivalent of the index factor selected in the preceding step.

*RCN = $100,000 × 1.37 = $137,000*

### Exercise 3

In 1995 a company purchased laboratory centrifuge equipment for $75,000. If the economic life of laboratory equipment is 10 years, what is the recommended maximum index factor for use in valuing the equipment, as of lien date 2011 (January 1); and what is its RCN?

Solution

**Solution:**

**Recommended Maximum Index Factor**

- Maximum Index Factor Age = Economic Life × 125% (converted to a decimal equivalent)
- Maximum Index Factor Age =
**13 years** (10 years × 1.25)

- Maximum Index Factor Year = Valuation Lien Date Year - Maximum Index Factor Age
- Maximum Index Factor Year =
**1998** (2011 - 13 years)

- Recommended Maximum Index Factor =
**134** (Table 1 index factor for 1998)

- Calculate the Maximum Index Factor Age for the equipment, using the formula:

Equipment Economic Life (years) × 125% = Maximum Index Factor Age (years)*.

*10 years × 1.25 = 13 years *(rounded to the nearest whole number)*

- Calculate the Maximum Index Factor Year for the equipment, using the formula:

Valuation Lien Date Year - Maximum Index Factor Age = Maximum Index Factor Year.

*2011 - 13 years = 1998*

- Locate the Recommended Maximum Index Factor by finding the “commercial” equipment index factor corresponding to the Maximum Index Factor Year (1998), using Table 1 of the January 2011 AH 581.

*1998 = 134*

**RCN**

- Acquisition Year Index Factor =
**139** (Table 1 index factor for 1995)

- The lesser of the Recommended Maximum Index Factor and the Acquisition Year Index Factor =
**134** < 139

- RCN = Cost × Index Factor (converted to decimal equivalent)
- RCN = $75,000 × 1.34
- RCN = $100,500

- Locate the Acquisition Year Index Factor by finding the "commercial" equipment index factor corresponding to the year that the equipment being valued was acquired (1995), using Table 1 of the January 2011 AH 581.

*1995 = 139*

- Select the lesser of the Recommended Maximum Index Factor and the Acquisition Year Index Factor for use in valuing the equipment.

*134 < 139*

- Calculate the RCN (2011) for the equipment, by multiplying the acquisition cost of the equipment by the decimal equivalent of the index factor selected in the preceding step.

*RCN = $75,000 × 1.34 = $100,500*

### Exercise 4

In 1987 a cannery operator purchased cannery equipment for $825,000. If the economic life of cannery equipment is 17 years, what is the recommended maximum index factor for use in valuing this equipment, as of lien date 2011 (January 1); and what is its RCN?

Solution

**Solution:**

**Recommended Maximum Index Factor**

- Maximum Index Factor Age = Economic Life × 125% (converted to a decimal equivalent)
- Maximum Index Factor Age =
**21 years** (17 years × 1.25)

- Maximum Index Factor Year = Valuation Lien Date Year - Maximum Index Factor Age
- Maximum Index Factor Year =
**1990** (2011 - 21 years)

- Recommended Maximum Index Factor =
**143** (Table 2 index factor for 1990)

- Calculate the Maximum Index Factor Age for the equipment, using the formula:

Equipment Economic Life (years) × 125% = Maximum Index Factor Age (years)*.

*17 years × 1.25 = 21 years *(rounded to the nearest whole number)*

- Calculate the Maximum Index Factor Year for the equipment, using the formula:

Valuation Lien Date Year - Maximum Index Factor Age = Maximum Index Factor Year.

*2011 - 21 years = 1990*

*1990 = 143 *

**RCN**

- Acquisition Year Index Factor = 161 (Table 2 index factor for 1987)

- The lesser of the Recommended Maximum Index Factor and the Acquisition Year Index Factor =
**143** < 161

- RCN = Cost × Index Factor (converted to decimal equivalent)
- RCN = $825,000 × 1.43
- RCN = $1,179,750

- Determine the Acquisition Year Index Factor by finding the "industrial" equipment index factor corresponding to the year that the equipment being valued was acquired (1987), using Table 2 of the January 2011 AH 581.
