Fair Value Disclosures [Abstract] |
Fair Value Measures | Fair Value Measures The Company measures certain financial assets at fair value. Fair value is determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy, as follows: Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market Level 2 – inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability The following table presents the Company’s financial assets measured and recorded at fair value on a recurring basis using the above input categories as of December 30, 2023 and September 30, 2023 (in thousands):

The Company had no liabilities measured and recorded at fair value on a recurring basis as of December 30, 2023 and September 30, 2023. The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. The fair value of the Company’s investments in certain money market funds is their face value and such instruments are classified as Level 1 and are included in cash and cash equivalents on the consolidated balance sheets. At December 30, 2023, Level 2 securities were priced by pricing vendors. These pricing vendors utilize the most recent observable market information in pricing these securities or, if specific prices are not available for these securities, use other observable inputs like market transactions involving identical or comparable securities. At December 30, 2023, the amortized cost of the Company’s U.S. Treasury securities is $184.4 million, with unrealized gains of $4.6 million and no unrealized losses, resulting in a fair value of $189.0 million. As applicable, when making the determination as to whether unrealized losses are other-than-temporary, the Company considers the length of time and extent to which each investment has been in an unrealized loss position, the financial condition and near-term prospects of the issuers, the issuers’ credit rating, and the time to maturity. There were no cash and cash equivalents related to U.S. Treasury securities with an original maturity of three months or less included in the amortized cost of $184.4 million
