Impairment of long-lived assets

Impairment of long-lived assets

The Company evaluates long-lived assets (including intangible assets) for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset may not be recoverable. A factor considered important that could trigger an impairment review includes a year-to-date loss from operations. An asset is considered impaired if its carrying amount exceeds the undiscounted future net cash flow the asset is expected to generate. The Company has a year-to-date loss, but based on the Company's review, there was no impairment of long-lived assets as of April 30, 2018 or January 31, 2018.

Goodwill. The purchase price of an acquired company is allocated between intangible assets and the net tangible assets of the acquired business with the residual of the purchase price recorded as goodwill. All identifiable goodwill as of April 30, 2018 and January 31, 2018 was attributable to the purchase of Perma-Pipe Canada, Ltd.

The Company performs an impairment assessment of goodwill annually as of January 31, or more frequently if triggering events occur, based on the estimated fair value of the related reporting unit or intangible asset. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. There was no impairment to goodwill as of April 30, 2018 or January 31, 2018.
