Capital assets and infrastructure are to be reported at historical (acquired) cost. A  county may use any established tool to accomplish GASB Statement 34 historical  cost requirements; however, the mechanism for calculating historical costs for  previously acquired assets should be (1) accurate, (2) able to be replicated, and (3)  documented. An asset’s total historical cost includes all costs of construction and/or  installation and setup of the assets (i.e. shipping, engineering and architect fees, and  capitalized interest during construction of a building). An asset’s historical cost can  be identified through deeds, bills of sale, county commission minutes, and/or  invoices. If the actual historical cost of an asset cannot be identified, an estimated  historical cost can be used. A county can estimate the historical cost of assets or  infrastructure by identifying an accurate estimate of an asset’s current replacement  cost and then using a deflation calculator to arrive at an estimated historical cost.  While there are a number of inflation/deflation calculators available, an excellent calculator that utilizes the consumer price index (CPI) is available on the Federal  Reserve Bank of Minneapolis Web site.

A county identifies a 10-acre tract of land that it owns through the register of deeds  office. Even though the county has the deed to the land, there is no price amount on the deed. Based on historical research, management ascertains that the land was  donated to the county board of education in 1948. The county property assessor  values the land (based on what a similar piece of land in the county would cost  today) at $80,000. Using a deflation calculator, management calculates that the  replacement cost of the land in 1948 would be $9,568. The county would record the  asset with an estimated historical cost of $9,568 and print off the calculation, a copy  of the deed, and documentation from the property assessor stating his/her estimate  for backup documentation for the asset’s cost.
