Significant Accounting Policies |
Significant Accounting Policies | 1. Significant Accounting Policies Basis of Presentation and Principles of Consolidation The Condensed Consolidated Financial Statements included herein are unaudited; however, they contain all normal recurring accruals and adjustments which, in the opinion of management, are necessary to present fairly the condensed consolidated financial position of Silicon Laboratories Inc. and its subsidiaries (collectively, the “Company”) at June 30, 2018 and December 30, 2017, the condensed consolidated results of its operations for the three and six months ended June 30, 2018 and July 1, 2017, the Condensed Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2018 and July 1, 2017, and the Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2018 and July 1, 2017. All intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of the results to be expected for the full year. The accompanying unaudited Condensed Consolidated Financial Statements do not include certain footnotes and financial presentations normally required under U.S. generally accepted accounting principles (GAAP). Therefore, these Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto for the year ended December 30, 2017, included in the Company’s Form 10-K filed with the Securities and Exchange Commission (SEC) on January 31, 2018. The Company prepares financial statements on a 52- or 53-week fiscal year that ends on the Saturday closest to December 31. Fiscal 2018 will have 52 weeks and fiscal 2017 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 accounting principles generally accepted in the United States 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, investments in auction-rate securities, 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. Reclassifications Certain reclassifications have been made to prior year financial statements to conform to current year presentation. Adoption of New Revenue Accounting Standard The Company adopted Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers, on December 31, 2017, the first day of its fiscal year ending December 29, 2018. The Company elected the modified retrospective method of adoption which only applies to those contracts which were not completed as of December 31, 2017. Prior periods have not been adjusted. In connection with its adoption of ASC 606, the Company recorded a cumulative-effect adjustment to retained earnings of $26.2 million on December 31, 2017. The following reflects the material changes recorded in connection with the cumulative-effect adjustment (in thousands):
Financial Statement Line Item |  | Increase (Decrease) |
Accounts receivable, net |  | $ | 230 |
Prepaid expenses and other current assets |  | $ | 7,579 |
Other assets, net |  | $ | (2,282 | )

Deferred income on shipments to distributors |  | $ | (50,115 | )
Other current liabilities |  | $ | 1,641 |
Retained earnings |  | $ | 26,195 |

* Excludes line items that were not materially affected by the Company’s adoption of ASC 606. The adoption had no impact to cash provided by or used in net operating, investing or financing activities in the Condensed Consolidated Statements of Cash Flows. ** Balance sheet line item amounts include the cumulative-effect adjustment recorded on December 31, 2017. The primary impact of the Company’s adoption of ASC 606 resulted from the acceleration of the timing of revenue recognition on sales to distributors. The Company previously deferred revenue and cost of revenue on such sales until the distributors sold the product to the end customers. The Company now recognizes revenue at the time of sale to the distributor provided all other revenue recognition criteria have been met. The Company records a right of return asset and a returns liability in place of the deferred income on shipments to distributors previously recorded under ASC 605. Revenue Recognition Revenue is recognized when control of the promised goods or services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Performance Obligations Substantially all of the Company’s contracts with customers contain a single performance obligation, the sale of mixed-signal integrated circuit (IC) products. Such sales represent a single performance obligation because the sale is one type of good (e.g. an IC) or includes multiple goods that are neither capable of being distinct nor separable from the other promises in the contract (e.g. an IC embedded with software). 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 and with an original expected duration of one year or less. As allowed under ASC 606, 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 Company’s products carry a one-year replacement warranty. The replacement warranty promises customers that delivered products are as specified in the contract (an “assurance-type warranty”). Therefore, the Company accounts for such warranties under ASC 460, Guarantees, and not as a separate performance obligation. Transaction Price 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. Fixed consideration primarily includes sales to direct customers and sales to distributors in which both the sale to the distributor and the sale to the end customer occur within the same reporting period. Variable consideration includes sales in which the amount of consideration that the Company will receive is unknown as of the end of a reporting period. Such 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. Stock rotation allows distributors limited levels of returns and is based on the distributor’s prior purchases. Price protection represents price discounts granted to certain distributors and is based on negotiations on sales to end customers. The Company estimates variable consideration at the most likely amount to which it expects to be entitled. Included in the transaction price estimate are amounts in which it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. 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. Contract Balances Accounts receivable represents the Company’s unconditional right to receive consideration from its customer. Payments are typically due within 30 days of invoicing and do not include a significant financing component. To date, there have been no material impairment losses on accounts receivable. There were no material contract assets or contract liabilities recorded on the Condensed Consolidated Balance Sheet in any of the periods presented. Recent Accounting Pronouncements In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The Company early adopted this ASU on December 31, 2017. The adoption did not have a material impact on its financial statements. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The objectives of this ASU are to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and to make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. This ASU is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The Company early adopted this ASU on December 31, 2017. The adoption did not have a material impact on its financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU eliminates Step 2 from the goodwill impairment test. Instead, an entity should recognize an impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to that reporting unit. This ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company is currently evaluating the effect of the adoption of this ASU, but anticipates that the adoption will not have a material impact on its financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU requires instruments measured at amortized cost to be presented at the net amount expected to be collected. Entities are also required to record allowances for available-for-sale debt securities rather than reduce the carrying amount. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company expects that the adoption will not have a material impact on its financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. For operating leases, a lessee is required to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is evaluating the effect that the adoption of this ASU will have on its financial statements. The Company currently expects that most of its operating lease commitments will be subject to the new standard and recognized as right-of-use assets and operating lease liabilities upon the adoption of ASU 2016-02, which will increase the total assets and total liabilities that it reports relative to such amounts prior to adoption.
