Significant Accounting Policies |
Significant Accounting Policies | 1. Significant Accounting Policies ​ Basis of Presentation and Principles of Consolidation ​ The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. The information included herein contains all normal recurring accruals and adjustments which, in the opinion of management, are necessary to present fairly Silicon Laboratories Inc.’s (the “Company”) financial position, results of its operations, comprehensive income, stockholders’ equity and cash flows. The Condensed Consolidated Balance Sheet as of January 1, 2022 was derived from the Company’s audited Consolidated Financial Statements. All intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated results of operations for the three and six months ended July 2, 2022 are not necessarily indicative of the results to be expected for the full year. ​ These Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto for the year ended January 1, 2022, included in the Company’s Form 10-K filed with the Securities and Exchange Commission (SEC) on February 2, 2022. ​ The Company prepares financial statements on a 52- or 53-week fiscal year that ends on the Saturday closest to December 31. Fiscal 2022 will have 52 weeks and fiscal 2021 had 52 weeks. In a 52-week year, each fiscal quarter consists of 13 weeks. ​ Use of Estimates ​ The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Among the significant estimates affecting the financial statements are those related to inventories, goodwill, acquired intangible assets, other long-lived assets, revenue recognition, stock-based compensation and income taxes. Actual results could differ from those estimates, and such differences could be material to the financial statements. The Company periodically reviews the assumptions used in its financial statement estimates. ​ Revenue Recognition ​ Revenue is recognized when control of the promised goods or services is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Substantially all of the Company’s contracts with customers contain a single performance obligation, the sale of mixed-signal integrated circuit (IC) products. This performance obligation is satisfied when control of the product is transferred to the customer, which typically occurs upon delivery. Unsatisfied performance obligations primarily represent contracts for products with future delivery dates. The Company has opted to not disclose the amount of unsatisfied performance obligations as these contracts have original expected durations of less than one year. ​ The transaction price reflects the Company’s expectations about the consideration it will be entitled to receive from the customer and may include fixed or variable amounts. Variable consideration primarily includes sales made to distributors under agreements allowing certain rights of return, referred to as stock rotation, and credits issued to the distributor due to price protection. The Company estimates variable consideration at the most likely amount to which it expects to be entitled. The estimate is based on information available to the Company, including recent sales activity and pricing data. The Company applies a constraint to its variable consideration estimate which considers both the likelihood of a return and the amount of a potential price concession. Variable consideration that does not meet revenue recognition criteria is deferred. The Company records a right of return asset in prepaid expenses and other current assets for the costs of distributor inventory not meeting revenue recognition criteria. A corresponding deferred revenue and returns liability amount is recorded for unrecognized revenue associated with such costs. The Company’s products carry a one-year replacement warranty. Payments are typically due within 30 days of invoicing and do not include a significant financing component. ​ 1. Significant Accounting Policies (Continued) Adoption of New Accounting Standard ​ Convertible Instruments ​ The Company adopted Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40, on January 2, 2022, the first day of its fiscal year ending December 31, 2022. The Company elected the modified retrospective transition method of adoption at the beginning of the period of adoption through a cumulative-effect adjustment. Prior periods have not been adjusted. The following reflects the material changes recorded in connection with the cumulative-effect adjustment (in thousands): ​
​ | ​ | ​ | ​
​ |  | Increase
Financial Statement Line Item | ​ | (Decrease)
Current portion of convertible debt, net | ​ | $ | 76,991
Other non-current liabilities | ​ | $ | (17,028)
Retained earnings | ​ | $ | (59,963)
​ The primary impact of the Company’s adoption of ASU 2020-06 was to increase the carrying value of its convertible debt, representing the unamortized debt discount, and reduce deferred tax liabilities related to convertible debt. The adoption reduced reported interest expense recorded in connection with convertible debt, which increased basic earnings per share and diluted earnings per share by $0.11 and $0.11, respectively, for the three months ended July 2, 2022, and by $0.22 and $0.21, respectively, for the six months ended July 2, 2022.
