The Company tests goodwill for impairment annually as of July 31 or more frequently if events or changes in circumstances indicate the asset might be impaired.

During the second quarter of fiscal 2024, the Company determined a triggering event had occurred for one of its reporting units due to year-to-date results and projections for the remainder of fiscal 2024 being lower than the forecast used in the previous annual goodwill impairment test, and a quantitative test of goodwill for possible impairment was necessary. As a result of the goodwill impairment test, the Company recorded a non-cash impairment charge of $230 million within restructuring and impairment costs in the consolidated statements of income, which was determined by comparing the carrying amount of the reporting unit to its fair value. The Company used a discounted cash flow model to estimate the fair value of the reporting unit. The primary assumptions used in the model were management's internal projections of future
cash flows, the weighted-average cost of capital and the long-term growth rate, which are classified as Level 3 inputs within the fair value hierarchy as defined in ASC 820, "Fair Value Measurement." The reporting unit whose goodwill was impaired was previously disclosed as being at risk of impairment in the Company’s Annual Report on Form 10-K for the year-ended September 30, 2023. It is possible that future changes in circumstances, including an increase in the discount rate or a decrease in the revenue growth rates, could result in an additional non-cash impairment charge of the remaining $212 million of goodwill for this reporting unit.

There were no other triggering events requiring an impairment assessment be conducted in the nine months ended June 30, 2024.
