Impairment of long-lived assets

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. Based on the Company's review there was no impairment of long-lived assets as of October 31, 2016 and January 31, 2016.

Goodwill. Goodwill represents the excess of purchase price over the fair value of the net assets acquired in conjunction with the Company’s acquisition of BPPC. The Company does not amortize goodwill. The Company performs an impairment assessment of goodwill annually, 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.
