(2) The department will utilize the depreciation schedules set forth above as reflected in the following example:

 

EXAMPLE

The Trending/Depreciation Procedure

 

In order to use the economic age-life method to value machinery and equipment, several steps must be followed.

1. Determine the economic life of the subject industry.

2. Acquire a set of reasonable trends for that economic life.

3. Acquire the original installed cost (direct and indirect) for the subject equipment.

4. Apply the appropriate trend factor to the original installed cost to determine replacement cost new (RCN) .

5. Depreciate the RCN on the basis of age to arrive at sound value.

 

Example:

 

Industry - Sawmill

Economic life - 10 years

2013 Table - Table 18

Case	I	II
Equipment - Motor Original Installed Cost	$ 200	$ 100
Year Installed	2005	1987

 

Case I		Case II
Cost	$ 200	Cost	$ 100
x Trend	1.215	x Trend	1.352*
RCN	$ 243	RCN	$ 135
x % Good	.30	x % Good	.20
Sound Value	$ 73	Sound Value	$ 27

 

*The trending factor is applied only to the last year of the economic life. Although the equipment is more than 20 years old, it is trended by the 10th year trend.
