Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC 820 establishes a single authoritative definition of fair value, a framework for measuring fair value and expands disclosure of fair value measurements. ASC 820 requires financial assets and liabilities to be categorized based on the inputs used to calculate their fair values as follows: Level 1 - Quoted prices in active markets for identical assets or liabilities. Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 - Unobservable inputs for the asset or liability, which reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). The Company’s financial instruments include cash and equivalents, short-term investments, accounts receivable and payable, short-term borrowings, and accrued liabilities. The carrying amount of these instruments approximates fair value because of their short-term nature. Assets and Liabilities Measured at Fair Value on a Recurring Basis The Company's financial assets and liabilities measured at fair value on a recurring basis consist of contingent consideration within Level 3 of the fair value hierarchy. Such amounts are not material for all periods presented. Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis The Company measures certain non-financial assets and liabilities, including long-lived assets, goodwill and intangible assets, at fair value on a non-recurring basis. Fair value measurements of non-financial assets and non-financial liabilities are used primarily in the impairment analyses of long-lived assets, goodwill and other intangible assets. During the three and nine month periods ended June 28, 2025 and June 29, 2024, the Company was not required to measure any significant non-financial assets and liabilities at fair value. Fair Value of Other Financial Instruments In April 2021, the Company issued $400 million aggregate principal amount of 4.125% senior notes due April 2031 (the "2031 Notes"). The estimated fair value of the Company's 2031 Notes as of June 28, 2025, June 29, 2024 and September 28, 2024 was $371.4 million, $352.2 million and $367.2 million, respectively, compared to a carrying value of $396.5 million, $395.9 million and $396.0 million, respectively. In October 2020, the Company issued $500 million aggregate principal amount of 4.125% senior notes due October 2030 (the "2030 Notes"). The estimated fair value of the Company's 2030 Notes as of June 28, 2025, June 29, 2024 and September 28, 2024 was $471.7 million, $445.7 million and $465.2 million, respectively, compared to a carrying value of $495.8 million, $495.0 million and $495.2 million, respectively. In December 2017, the Company issued $300 million aggregate principal amount of 5.125% senior notes due February 2028 (the "2028 Notes"). The estimated fair value of the Company's 2028 Notes as of June 28, 2025, June 29, 2024 and September 28, 2024 was $300.3 million, $291.6 million and $299.2 million, respectively, compared to a carrying value of $298.8 million, $298.3 million and $298.4 million, respectively. The estimated fair value is based on quoted market prices for these notes, which are Level 2 inputs within the fair value hierarchy.
