** The fair value of this equity investment is measured at NAV which approximates fair value and is not classified within the fair value hierarchy.
The Company uses the fair value hierarchy for financial assets and liabilities. The carrying amounts of other current financial assets and other current financial liabilities approximate fair value due to their short-term nature.
Interest income from cash, cash equivalents, and investments was $40.8 million, $35.1 million and $18.2 million for the years ended September 30, 2025, 2024, and 2023, respectively. Interest income is included in other income (expense), net on the Company's consolidated income statements. There were no unrealized losses on investments that were held for a period greater than 12 months at September 30, 2025 and 2024.
The Company determined that as of September 30, 2025, there were no credit losses on any investments within its portfolio.
Assets Measured and Recorded at Fair Value on a Non-Recurring Basis
The Company’s non-financial long-lived assets, which include goodwill and other intangible assets, are not required to be carried at fair value on a recurring basis. These non-financial assets are measured at fair value on a non-recurring basis when there is an indicator of impairment, and they are recorded at fair value only when impairment is recognized. The Company reviews goodwill for impairment annually, during the second quarter of each fiscal year, or as circumstances indicate the possibility of impairment. The Company monitors the carrying value of tangible and intangible long-lived assets for impairment whenever events or changes in circumstances indicate its carrying amount may not be recoverable.
During the year ended September 30, 2023, the Company recorded an impairment of $3.5 million against the operating lease right-of-use asset related to its third quarter of fiscal 2023 restructuring plan, see Note 13, Restructuring Charges. The charge was reflected in the Restructuring Charges line item on the Company's consolidated income statement.
The Company did not recognize any other material impairment charges related to non-financial long-lived assets for the years ended September 30, 2025, 2024, and 2023.

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
