Goodwill and Intangible Assets Disclosure [Abstract]

NOTE 4 GOODWILL AND INTANGIBLE ASSETS

Goodwill

Goodwill represents the excess of the purchase price over the fair values of the assets acquired and liabilities assumed in a business combination, at the date of acquisition. Goodwill is not amortized but is tested for potential impairment at the reporting unit level, at a minimum on an annual basis in the fourth fiscal quarter, or when indications of potential impairment exist. All of our goodwill is within our North America Solutions reportable segment.

During the three months ended December 31, 2022, we had no additions or impairments to goodwill. As of December 31, 2022 and September 30, 2022, the goodwill balance was $45.7 million.

Intangible Assets

Finite-lived intangible assets are amortized using the straight-line method over the period in which these assets contribute to our cash flows and are evaluated for impairment in accordance with our policies for valuation of long-lived assets. All of our intangible assets are within our North America Solutions reportable segment and consist of the following:
