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. Piping Systems has a year-to-date loss, but based on the Company's review, there was no impairment of long-lived assets as of October 31, 2017 or January 31, 2017.

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 October 31, 2017 and January 31, 2017 is attributable to the purchase of Perma-Pipe Canada, Ltd. ("PPC")

In January 2017, the Financial Accounting Standards Board ("FASB") issued authoritative guidance that simplifies the assessment of goodwill for impairment when the estimated fair value of a reporting unit is less than its carrying value by eliminating the requirement to determine the fair value of goodwill. Under the new guidance, the amount of goodwill impairment will be determined by the amount the carrying value of the reporting unit exceeds its fair value. The new guidance is effective for the Company beginning January 1, 2020, with early adoption permitted. The Company adopted this new guidance in the fourth quarter of 2016.

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 October 31, 2017.
