The following table sets forth by level within the fair value hierarchy our financial assets and liabilities that were accounted for at fair value on a recurring basis as of January 25, 2025 and April 27, 2024 according to the valuation techniques we used to determine their fair values. There have been no transfers of assets or liabilities among the fair value hierarchies presented.

We elected to value the Convertible Note at fair value in accordance with ASC 825-10-15-4(a) because of the embedded derivatives contained in the Convertible Note. The fair value of the Convertible Note as of April 27, 2024 was estimated using the binomial lattice model. The fair value of the Convertible Note as of January 25, 2025 was estimated using the MCS. Both models allow for the examination of the value to a holder and an understanding of the investment decision that would occur at each node.

The fair value of the Convertible Note entered into during the first quarter of fiscal 2024 was classified as Level 3 because certain inputs for the valuation were not readily determinable or observable.

See "Note 7. Financing Agreements" and the Form 10-K for additional information on the methods and assumptions used to estimate the fair value of each class of financial instrument.
