Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Overview and Basis of Presentation	1. Business Overview and Basis of Presentation Description of business Sonos, Inc. and its wholly owned subsidiaries (collectively, "Sonos," the "Company," "we," "us" or "our") designs, develops, manufactures, and sells audio products and services. The Sonos sound system provides customers with an immersive listening experience created by the design of its speakers, headphones and components a proprietary software platform, and the ability to stream content from a variety of sources over the customer’s wireless network or over Bluetooth. The Company’s products are sold through third-party physical retailers, including custom installers of home audio systems, select e-commerce retailers, and its website, sonos.com. The Company’s products are distributed in over 60 countries through its wholly owned subsidiaries: Sonos Europe B.V. in the Netherlands, Beijing Sonos Technology Co. Ltd. in China, Sonos Japan GK in Japan, and Sonos Australia Pty Ltd. in Australia. Basis of presentation and preparation The accompanying condensed consolidated financial statements are unaudited. The condensed consolidated balance sheet as of September 30, 2023, has been derived from the audited consolidated financial statements of the Company. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all the information and footnotes required by U.S. GAAP for annual financial statements. They should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023, (the "Annual Report"), filed with the SEC on November 20, 2023. In management’s opinion, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of only normal recurring adjustments, necessary for the fair statement of the Company’s financial position, its results of operations, and its cash flows for the interim periods presented. The results of operations for the three and nine months ended June 29, 2024, are not necessarily indicative of the results to be expected for the full fiscal year or any other period. The Company operates on a 52- week or 53- week fiscal year ending on the Saturday nearest September 30 each year. The Company’s fiscal year is divided into four quarters of 13 weeks, each beginning on a Sunday and containing two 4-week periods followed by a 5-week period. An additional week is included in the fourth fiscal quarter approximately every five years to realign fiscal quarters with calendar quarters. This last occurred in the fourth quarter of the Company’s fiscal year ended October 3, 2020, and will reoccur in the fiscal year ending October 3, 2026. The nine months ended June 29, 2024 and July 1, 2023, spanned 39 weeks each. As used in this Quarterly Report on Form 10-Q, "fiscal 2024" refers to the fiscal year ending September 28, 2024, "fiscal 2023" refers to the fiscal year ended September 30, 2023, "fiscal 2022" refers to the fiscal year ended October 1, 2022, "fiscal 2021" refers to the fiscal year ended October 2, 2021, and "fiscal 2020" refers to the fiscal year ended October 3, 2020. Use of estimates and judgments The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates and judgments compared to historical experience and expected trends.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies There have been no changes in the Company’s significant accounting policies, recently adopted accounting pronouncements, or recent accounting pronouncements pending adoption from those disclosed in the Annual Report, except as noted below. Marketable securities The Company’s marketable securities consist of U.S. Treasury securities. Management determines the appropriate classification of its marketable securities at the time of purchase and reevaluates such determination at each balance sheet date. The Company classifies its marketable securities as available-for-sale and reports them at fair value in the condensed consolidated balance sheets, with unrealized gains and losses recorded in accumulated other comprehensive (income) loss. If securities are sold prior to maturity, the cost of securities sold is based on the specific identification method. Realized gains and losses on the sale of securities are recorded in other income (expense), net in the condensed consolidated statement of operations and comprehensive income (loss). For securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more-likely-than-not that it will be required to sell, the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through earnings. For securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in accumulated other comprehensive loss in the condensed consolidated balance sheets. Recent accounting pronouncements pending adoption In December 2023, the Financial Accounting Standards Board ("FASB") issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This update includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The amendments are effective for fiscal years beginning after December 15, 2024, with early adoption permitted, and may be applied either prospectively or retrospectively. The Company is currently evaluating the pronouncement to determine the impact it may have on the Company's condensed consolidated financial statements and related disclosures.

Fair Value Disclosures [Abstract]
Fair Value Measurements	3. Fair Value Measurements The carrying values of the Company’s financial instruments, including accounts receivable and accounts payable, approximate their fair values due to the short period of time to maturity or repayment. The Company utilizes the following fair value hierarchy to establish priorities of the inputs used to measure fair value: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Observable inputs other than quoted market prices included in Level 1, such as quoted prices for similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. The following table summarizes fair value measurements by level for the assets measured at fair value on a recurring basis as of June 29, 2024 and September 30, 2023: June 29, 2024 Level 1 Level 2 Level 3 Total (In thousands) Assets: Cash equivalents: Money market funds $ 30,289 $ — $ — $ 30,289 U.S. Treasury securities — 1,247 — 1,247 Total cash equivalents 30,289 1,247 31,536 Marketable Securities: U.S. Treasury securities — 49,515 — 49,515 Total marketable securities — 49,515 — 49,515 Total assets $ 30,289 $ 50,762 $ — $ 81,051 September 30, 2023 Level 1 Level 2 Level 3 Total (In thousands) Assets: Cash equivalents: Money market funds $ 51,522 $ — $ — $ 51,522 Total Assets $ 51,522 $ — $ — $ 51,522

Financial Instruments	4. Financial Instruments The Company classifies its marketable securities as available-for-sale and reports them at fair value in the condensed consolidated balance sheets, with unrealized gains and losses recorded in accumulated other comprehensive income (loss). Classification of the Company's marketable securities in the condensed consolidated balance sheets is based on each instrument’s underlying contractual maturity date. Securities with an original maturity of three months or less at time of purchase are recorded in cash and cash equivalents. Securities with an original maturity of greater than three months but less than one year are recorded in marketable securities. As of June 29, 2024, the Company held no securities with original maturities exceeding one year. Realized gains and losses on the sale of securities are recorded in other income (expense), net in the condensed consolidated statements of operations and comprehensive income (loss).

There were no realized gains or losses on sales of marketable securities during the three and nine months ended June 29, 2024. For securities in an unrealized loss position, the Company evaluated whether the decline in fair value resulted from credit losses or other factors and concluded these amounts were related to temporary fluctuations in value of the securities and were due primarily to changes in interest rates and market conditions of the underlying securities. The Company does not intend to sell the securities, and it is more-likely-than-not that it will not be required to sell before recovery of their amortized cost basis. Accordingly, an allowance for credit losses was deemed unnecessary for these securities as of June 29, 2024. The Company has elected the practical expedient to exclude the applicable accrued interest from both the fair value and the amortized cost basis of its marketable securities for the purpose of identifying and measuring impairment. The Company presents accrued interest receivable related to its marketable securities in prepaid and other current assets, separate from marketable securities, on its condensed consolidated balance sheets. Accrued interest receivable related to our marketable securities was immaterial as of June 29, 2024. The Company's accounting policy is to not measure an allowance for credit losses for accrued interest receivable and to write-off any uncollectible accrued interest receivable as a reversal of interest income in a timely manner, which it considers to be in the period in which it determines the accrued interest will not be collected. No accrued interest receivables were written off during the three and nine months ended June 29, 2024.

Debt	7. Debt On October 13, 2021, the Company entered into a Revolving Credit Agreement with JPMorgan Chase Bank, N.A., as the administrative agent, and Bank of America N.A., Morgan Stanley Senior Funding, Inc., and Goldman Sachs Bank USA as the other lenders party thereto (the "Revolving Credit Agreement"). The Revolving Credit Agreement provides for (i) a five-year senior secured revolving credit facility in the amount of up to $100.0 million and (ii) an uncommitted incremental facility subject to certain conditions. Proceeds are to be used for working capital and general corporate purposes. In June 2023, the Company amended the Revolving Credit Agreement, replacing prior references to LIBOR with references to SOFR as a result of the discontinuation of LIBOR. The facility may be drawn as an Alternative Base Rate Loan (at 1.00% plus an applicable margin) or Term Benchmark Loan (at the Term SOFR Rate, plus the applicable Term SOFR Adjustment ranging from 0.11% to 0.43%, plus an applicable margin (in total, "Adjusted Term SOFR")). The Company must also pay (i) an unused commitment fee ranging from 0.200% to 0.275% per annum of the average daily unused portion of the aggregate revolving credit commitment under the agreement and (ii) a per annum fee equal to the applicable margin over Adjusted Term SOFR multiplied by the aggregate face amount of outstanding letters of credit. As of June 29, 2024, the Company did not have any outstanding borrowings and had $1.8 million in undrawn letters of credit that reduce the availability under the Revolving Credit Agreement. The Company’s obligations under the Revolving Credit Agreement are secured by substantially all of the Company’s assets. The Revolving Credit Agreement contains customary representations and warranties, customary affirmative and negative covenants, a financial covenant that is tested quarterly and requires the Company to maintain a certain consolidated leverage ratio, and customary events of default. As of June 29, 2024, the Company was in compliance with all financial covenants under the Revolving Credit Agreement.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	8. Commitments and Contingencies Commitments to suppliers As of June 29, 2024, the Company's open purchase orders to contract manufacturers for finished goods were approximately $142 million, the majority of which are expected to be paid over the next six months. As of June 29, 2024, the Company's expected commitments to suppliers for components were in the range of $280 million to $320 million, the majority of which is expected to be paid and/or utilized by our contract manufacturers in building finished goods within the next two years. The expected commitments are subject to change as a result of fluctuations in the demand forecast, as well as ongoing negotiations with contract manufacturers and suppliers. These commitments are related to components that can be specific to Sonos products and include the following: 1) indirect obligations to third-party manufacturers and suppliers, 2) the inventory owned by contract manufacturers procured to manufacture Sonos products, and 3) purchase commitments made by contract manufacturers to their upstream suppliers on behalf of the Company. Legal proceedings From time to time, the Company is involved in legal proceedings in the ordinary course of business, including claims relating to employee relations, business practices, and patent infringement. Litigation can be expensive and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict, and the Company’s view of these matters may change in the future as the litigation and events related thereto unfold. The Company expenses legal fees as incurred. The Company records a provision for contingent losses when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. An unfavorable outcome to any legal matter, if material, could have an adverse effect on the Company’s operations or its financial position, liquidity or results of operations. The Company’s Lawsuits Against Google: On January 7, 2020, the Company filed a complaint with the U.S. International Trade Commission ("ITC") against Alphabet Inc. ("Alphabet") and Google LLC ("Google") and a counterpart lawsuit in the U.S. District Court for the Central District of California against Google. The complaint and lawsuit each allege infringement by Alphabet and Google of certain Sonos patents related to its smart speakers and related technology. The counterpart lawsuit is stayed pending completion of the ITC investigation and appeal thereof. The ITC concluded its investigation in January 2022, finding all five of the Company’s asserted patents to be valid and infringed by Google, and further finding that one redesign per patent proposed by Google would avoid infringement. The ITC issued a limited exclusion order and a cease-and-desist order with respect to Google’s infringing products. The Company and Google each appealed the ITC’s determination, which was upheld in its entirety by a panel of the appeals court. Google has filed a petition for rehearing by the full appeals court. A decision is expected on this petition in August 2024. On September 29, 2020, the Company filed another lawsuit against Google alleging infringement of additional Sonos patents and seeking monetary damages and other non-monetary relief. A jury trial was held in May 2023, which found one Sonos patent to be infringed and another Sonos patent not infringed, and returned an award of $32.5 million based on a royalty rate of $2.30 per infringing unit. After trial, the court held Sonos’ patents unenforceable under the doctrine of prosecution laches and invalid as a result of amendments made during prosecution. The Company is appealing the ruling. Google’s Lawsuits Against the Company: On June 11, 2020, Google filed a lawsuit in the U.S. District Court for the Northern District of California against the Company alleging infringement by the Company of five Google patents and seeking monetary damages and other non-monetary relief. Four of these patents have since been found invalid by the Court or by the U.S. Patent and Trademark Office, or have been withdrawn from the case by Google. In this lawsuit, one patent remains asserted against the Company. No trial date is set. On June 12, 2020, Google filed lawsuits in District Court Munich I against Sonos Europe B.V. and Sonos, Inc., alleging infringement of two Google patents seeking monetary damages and an injunction preventing sales of allegedly infringing products. In March 2024, the Company received a judgment from the German Federal Patent Court invalidating one of the patents. Google has now dismissed its case against Sonos concerning this patent. In June 2021, the Munich court issued a decision dismissing Google's complaint regarding the other Google patent for lack of infringement by the Company. Google appealed the Munich court's ruling and, in April 2024, the appellate court in Munich rendered a judgment dismissing Google's appeal. On August 21, 2020, Google filed a lawsuit against Sonos Europe B.V. and Sonos, Inc. in France, alleging infringement of two Google patents seeking monetary damages and an injunction preventing sales of allegedly infringing products. In February 2021, Google withdrew its infringement allegations regarding one patent in view of prior art brought to the attention of the court by the Company. In March 2022, the French trial court ruled for the Company on one of Google's asserted patents. The French trial court found the other Google patent invalid in November 2023. Google appealed the French trial court's March 2022 and November 2023 rulings. In April 2024, Google dismissed its appeal of the November 2023 ruling, which is now final. In May 2024, Google's appeal of the March 2022 judgment was decided against Google and in favor of Sonos. On August 21, 2020, Google filed a lawsuit against Sonos Europe B.V. and Sonos, Inc. in the Netherlands alleging infringement of a Google patent seeking an injunction preventing sales of allegedly infringing products. In October 2022, the Netherlands court ruled that the Company does not infringe Google’s patent. In September 2020, Google filed a lawsuit against Sonos Europe B.V. in the Netherlands, alleging infringement of a Google patent and seeking an injunction preventing sales of allegedly infringing products. In February 2022, the Court rejected Google's claims concerning this patent. Google appealed this decision, which appeal was stayed in April 2024. On August 8, 2022, Google filed two complaints with the ITC against the Company and two counterpart lawsuits in the Northern District of California against the Company, collectively alleging infringement by the Company of seven Google patents generally related to wireless charging, device setup, and voice control, and seeking monetary damages and other non-monetary relief. The counterpart lawsuits are stayed pending completion of the ITC investigations. The ITC has terminated the investigation as to one Google patent as a result of imminent expiration of that Google patent. The first ITC investigation concluded in December 2023 with a final determination of no violation by the Company. Google chose not to appeal this determination. The oral hearing in the second ITC investigation has been postponed after the administrative law judge has indicated that she will be invalidating both Google patents at issue. Implicit On March 10, 2017, Implicit, LLC (“Implicit”) filed a patent infringement action in the United States District Court, District of Delaware against the Company. Implicit is asserting that the Company has infringed on certain claims of two patents in this case. The Company denies the allegations. The claims at issue have been held unpatentable by the U.S. Patent and Trademark Office. Implicit has appealed this ruling, which is currently scheduled to be heard by the appeals court in 2024. There is no assurance of a favorable outcome and the Company’s business could be adversely affected as a result of a finding that the Company patents-in-suit are invalid and/or unenforceable. A range of loss, if any, associated with this matter is not probable or reasonably estimable as of June 29, 2024.

Income Taxes

Income Taxes	Jun. 29, 2024
Income Tax Disclosure [Abstract]
Income Taxes	11. Income Taxes The Company’s income tax provision and the resulting effective tax rate for interim periods is generally determined based upon its estimated annual effective tax rate ("AETR"), adjusted for the effect of discrete items arising in that quarter. The impact of such inclusions could result in a higher or lower effective tax rate during a quarter, based upon the mix and timing of actual earnings or losses versus annual projections. In each quarter, the Company updates its estimate of the AETR, and if the estimated AETR changes, a cumulative adjustment is made in that quarter. The Company recorded a provision for income taxes of $8.9 million and $5.9 million for the three months ended June 29, 2024 and July 1, 2023, respectively, related to U.S. and non-U.S. income taxes. The Company recorded a provision for income taxes of $20.2 million and $16.0 million for the nine months ended June 29, 2024 and July 1, 2023, respectively, related to U.S. and non-U.S. income taxes. For the three and nine months ended June 29, 2024, and July 1, 2023, the Company calculated its U.S. income tax provision using the discrete method as though the interim year-to-date period was an annual period. The application of the AETR method generally required by ASC 740, Income Taxes, was not utilized to calculate the U.S. interim income tax provision given that deviations in the projected pre-tax net income (loss) in the U.S. could have resulted in a disproportionate and unreliable effective tax rate under the AETR method. For the three and nine months ended June 29, 2024, and July 1, 2023, the Company's U.S. income tax provision was adversely impacted by the requirement to capitalize and amortize research and development expenses under Section 174 of the U.S. Internal Revenue Code ("Section 174") as the Company recorded a current U.S. tax expense with no corresponding deferred tax benefit due to the valuation allowance maintained against its U.S. deferred tax assets. For the nine months ended June 29, 2024, the Company concluded that a full valuation allowance on its deferred tax assets in the U.S. continued to be appropriate considering cumulative pre-tax losses in recent years and uncertainty with respect to future taxable income. It is possible that within the next 12 months there may be sufficient positive evidence to release a portion or all of the remaining valuation allowance. Release of the valuation allowance in the U.S. would result in a benefit to the income tax provision in the period the release is recorded, which could have a material impact on net earnings. The timing and amount of the potential valuation allowance release are subject to significant management judgment, as well as prospective earnings in the U.S.

Net Income (Loss) Per Share	Jun. 29, 2024
Earnings Per Share [Abstract]
Net Income (Loss) Per Share	12. Net Income (Loss) Per Share Basic net income (loss) per share attributable to common stockholders is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average number of shares of common stock outstanding less shares subject to repurchase. Diluted net income (loss) per share attributable to common stockholders adjusts the basic net income (loss) per share attributable to common stockholders and the weighted-average number of shares of common stock outstanding for the potentially dilutive impact of stock awards, using the treasury stock method. The following table sets forth the computation of the Company’s basic and diluted net income (loss) per share attributable to common stockholders: Three Months Ended Nine Months Ended June 29, July 1, June 29, July 1, (In thousands, except share and per share data) Numerator: Net income (loss) attributable to common stockholders - basic and diluted $ 3,709 $ (23,571) $ 14,947 $ 20,966 Denominator: Weighted-average shares of common stock—basic 122,553,129 128,311,109 123,828,150 127,825,410 Effect of potentially dilutive stock options 1,116,000 — 956,598 2,164,370 Effect of RSUs 3,543,526 — 3,085,571 2,807,869 Effect of PSUs 32,804 — 16,049 53,730 Weighted-average shares of common stock—diluted 127,245,459 128,311,109 127,886,368 132,851,379 Net income (loss) per share attributable to common stockholders: Basic $ 0.03 $ (0.18) $ 0.12 $ 0.16 Diluted $ 0.03 $ (0.18) $ 0.12 $ 0.16 The following potentially dilutive shares were excluded from the computation of diluted net income (loss) per share attributable to common stockholders because including them would have been antidilutive: Three Months Ended Nine Months Ended June 29, July 1, June 29, July 1, Stock options to purchase common stock 6,371,604 9,035,818 6,998,738 7,525,339 Restricted stock units 9,556,879 9,569,869 9,828,619 7,429,364 Performance stock units 187,255 180,762 88,030 119,754 Total 16,115,738 18,786,449 16,915,387 15,074,457

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation and preparation	The accompanying condensed consolidated financial statements are unaudited. The condensed consolidated balance sheet as of September 30, 2023, has been derived from the audited consolidated financial statements of the Company. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all the information and footnotes required by U.S. GAAP for annual financial statements. They should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023, (the "Annual Report"), filed with the SEC on November 20, 2023. In management’s opinion, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of only normal recurring adjustments, necessary for the fair statement of the Company’s financial position, its results of operations, and its cash flows for the interim periods presented. The results of operations for the three and nine months ended June 29, 2024, are not necessarily indicative of the results to be expected for the full fiscal year or any other period. The Company operates on a 52- week or 53- week fiscal year ending on the Saturday nearest September 30 each year. The Company’s fiscal year is divided into four quarters of 13 weeks, each beginning on a Sunday and containing two 4-week periods followed by a 5-week period. An additional week is included in the fourth fiscal quarter approximately every five years to realign fiscal quarters with calendar quarters. This last occurred in the fourth quarter of the Company’s fiscal year ended October 3, 2020, and will reoccur in the fiscal year ending October 3, 2026. The nine months ended June 29, 2024 and July 1, 2023, spanned 39 weeks each. As used in this Quarterly Report on Form 10-Q, "fiscal 2024" refers to the fiscal year ending September 28, 2024, "fiscal 2023" refers to the fiscal year ended September 30, 2023, "fiscal 2022" refers to the fiscal year ended October 1, 2022, "fiscal 2021" refers to the fiscal year ended October 2, 2021, and "fiscal 2020" refers to the fiscal year ended October 3, 2020.
Use of estimates and judgments	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates and judgments compared to historical experience and expected trends.
Marketable securities	The Company’s marketable securities consist of U.S. Treasury securities. Management determines the appropriate classification of its marketable securities at the time of purchase and reevaluates such determination at each balance sheet date. The Company classifies its marketable securities as available-for-sale and reports them at fair value in the condensed consolidated balance sheets, with unrealized gains and losses recorded in accumulated other comprehensive (income) loss. If securities are sold prior to maturity, the cost of securities sold is based on the specific identification method. Realized gains and losses on the sale of securities are recorded in other income (expense), net in the condensed consolidated statement of operations and comprehensive income (loss). For securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more-likely-than-not that it will be required to sell, the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through earnings. For securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in accumulated other comprehensive loss in the condensed consolidated balance sheets.
Recent accounting pronouncements pending adoption	In December 2023, the Financial Accounting Standards Board ("FASB") issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This update includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The amendments are effective for fiscal years beginning after December 15, 2024, with early adoption permitted, and may be applied either prospectively or retrospectively. The Company is currently evaluating the pronouncement to determine the impact it may have on the Company's condensed consolidated financial statements and related disclosures.
Fair value of financial instruments, policy	The Company has elected the practical expedient to exclude the applicable accrued interest from both the fair value and the amortized cost basis of its marketable securities for the purpose of identifying and measuring impairment. The Company presents accrued interest receivable related to its marketable securities in prepaid and other current assets, separate from marketable securities, on its condensed consolidated balance sheets. Accrued interest receivable related to our marketable securities was immaterial as of June 29, 2024. The Company's accounting policy is to not measure an allowance for credit losses for accrued interest receivable and to write-off any uncollectible accrued interest receivable as a reversal of interest income in a timely manner, which it considers to be in the period in which it determines the accrued interest will not be collected
