- Definition This item represents an other than temporary decline in value that has been recognized against an investment accounted for under the cost method of accounting.

Evidence of a loss in value might include, but would not necessarily be limited to, absence of an ability to recover the carrying amount of the investment or inability of the investee to sustain an earnings capacity which would justify the carrying amount of the investment.
