CI(base yr) = cost index for the base year Notes: 1. As an example, if you are trying to calculate the cost of the exchanger for the year 2010, the most probable updated cost would be based on a ratio of the cost index for the year 2010 to the cost index for a base year of 2005. It is not recommended to use a base cost index more than 5 years older than the cost index for the calculated year. 2. The cost index ratio is subjective in nature and readers are exercised caution in determining the "Cost Index Ratio" for calculating the updated equipment cost. Readers and Members of "Cheresources", this is it for today's blog entry. Would welcome comments from all of you on the subject matter.
