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

2004 Table - Table 18

 

Case                                                                                        I                                 II

Equipment - Motor

Original Installed Cost                                                     $ 200                         $ 100

 

Year Installed                                                                     2000                         1977

 

          CaseI                                                                                        Case II

 

Cost                                       $ 200                                          Cost                  $ 100

x Trend                                  1.027                                           x Trend             1.125*

RCN                                         205                                           RCN                     113

x % Good                                 .67                                            x % Good             .20

Sound Value                       $ 138                                            Sound Value      $ 23

 

*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.
