Fair Value Disclosures [Abstract]  
Financial Instruments Financial Instruments
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs to valuation methodologies used to measure fair value:

Level 1-Valuations based on quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2-Valuations based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3-Valuations based on unobservable inputs reflecting the Company’s assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.

Cash equivalents are carried at cost, which approximates fair value and are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices.

Marketable securities are carried at fair value and are classified within Level 1 because they are valued using quoted market prices. Specific to marketable fixed income securities, the Company did not record any gross unrealized gains and losses as fair value approximates amortized cost. The Company did not record any credit losses during the thirteen and twenty-six weeks ended July 28, 2024. Further, as of July 28, 2024, the Company did not record an allowance for credit losses related to its fixed income securities.

Vested equity warrants and equity investments in public companies that have readily determinable fair values are carried at fair value and are classified as marketable securities within Level 1 because they are valued using quoted market prices.

Unvested equity warrants are classified within Level 3 of the fair value hierarchy as they are valued based on observable and unobservable inputs reflecting the Company’s assumptions, consistent with reasonably available assumptions made by other market participants. The Company utilized certain valuation techniques, such as the Black-Scholes option-pricing model and the Monte Carlo simulation model, to determine the fair value of unvested equity warrants. The application of these models requires the use of a number of complex assumptions based on unobservable inputs, including the expected term, expected equity volatility, discounts for lack of marketability, cash flow projections, and probability with respect to vesting requirements. Equity warrants are transferred from Level 3 to Level 1 of the fair value hierarchy upon vesting as they are no longer valued based on unobservable inputs.
