Fair Value Measurements

7. Fair Value Measurements

The valuation hierarchy for disclosure of assets and liabilities reported at fair value prioritizes the inputs for such valuations into three broad levels:

•Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;

•Level 2: quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; or

•Level 3: unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value.

A financial asset's or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Money market funds, time deposits, and corporate notes/bonds are classified within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets.

The principal market in which we execute our foreign currency derivatives is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants usually are large financial institutions. Our foreign currency derivatives’ valuation inputs are

based on quoted prices and quoted pricing intervals from public data sources and do not involve management judgment. These contracts are typically classified within Level 2 of the fair value hierarchy.

Our significant financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2024 and September 30, 2023 were as follows:

Level 3 Investments

Convertible Note

In the fourth quarter of 2021, we invested $2.0 million in a non-marketable convertible note. This debt security was classified as available-for-sale and included in Other assets on the Consolidated Balance Sheet. During the three months ended March 31, 2024, we recorded a $2.0 million impairment loss related to this Level 3 investment. The impairment loss is included in Other income (expense), net on the Consolidated Statements of Operations.
