Goodwill and Other Intangible Assets

Goodwill represents the excess of cost over the fair value of identifiable assets acquired. Goodwill is assessed for impairment on an annual basis as of July 31, either by first assessing qualitative factors to determine whether a quantitative goodwill impairment test is necessary or by proceeding directly to the quantitative test. The quantitative test may be required more frequently if triggering events or other circumstances occur that could indicate impairment. Goodwill is assessed for impairment at the reporting unit level, which has been determined to be our operating segments or one level below our operating segments in certain instances.

Changes in the carrying amount of goodwill for the years ended August 31, 2022 and 2021, are included in the table below.

No goodwill has been allocated to our Nitrogen Production segment, which consists of a single investment accounted for under the equity method of accounting, and allocated expenses.

No goodwill impairments were identified as a result of our annual goodwill analyses performed as of July 31, 2022, 2021 or 2020. Management will continue to monitor the results and projected cash flows for each of our businesses to assess whether any reserves or impairments may be necessary in the future.

Intangible assets subject to amortization primarily include customer lists, trademarks and noncompete agreements, and are amortized over their respective useful lives (ranging from two to 30 years). We have no material intangible assets with indefinite useful lives. All long-lived assets, including other identifiable intangible assets, are also assessed for impairment in accordance with U.S. GAAP and evaluated for impairment whenever triggering events or other circumstances indicate the carrying amount of an asset group or reporting unit may not be recoverable. Information regarding intangible assets is as follows:
