In other words, an accountant determines the value of an asset by referring to its cost when it was acquired/purchased, and NOT by the value of the returns which are expected to be gained from the use of the asset.

As an example, if a piece of equipment was acquired at a cost of $250,000 and in the course of the next few years was able to yield as much as $1m in returns, the accounting records would still show the asset as worth $250,000, which was the original cost (actual cost).
