Accounting Changes and Error Corrections [Abstract]
Accounting Changes and Error Corrections [Text Block]	Recent Accounting Changes and Accounting Pronouncements Adoption of New Accounting Guidance In the first quarter of fiscal 2017, the Company adopted an amended authoritative guidance simplifying the presentation of debt issuance costs as a direct deduction from the carrying value of the debt liability rather than showing the debt issuance costs as an asset. We have applied the amendment retrospectively to the comparable period presented and it did not have a significant impact on our financial statements. In the first quarter of fiscal 2017, the Company early adopted the authoritative guidance that simplifies how share-based payments are accounted for and presented in the financial statements. Under the new guidance, excess tax benefits or tax deficiencies are recorded in the condensed consolidated statement of income when the awards vest or are settled. Previously, they were recorded in stockholders' equity of the condensed consolidated balance sheet. In addition, cash flows related to excess tax benefits or tax deficiencies are now classified as an operating activity, with prior periods adjusted accordingly. While the new guidance provides an accounting policy election to account for forfeitures as they occur, the Company elected to continue to estimate forfeitures to determine the amount of compensation cost to be recognized in each period. As a result of the adoption of this guidance, the condensed consolidated statement of cash flows for the six months ended September 26, 2015 was adjusted as follows: a $10.5 million increase to net cash provided by operating activities and a $10.5 million increase to the net cash used in financing activities. Additionally, the Company recorded excess tax benefits of $2.9 million and $9.7 million, resulting in an increase in net income per diluted share of $0.01 and $0.03 for the second quarter and first six months, respectively, of fiscal 2017 in the condensed consolidated statement of income as a component of the provision for income taxes. Recent Accounting Pronouncements In April 2014, the Financial Accounting Standards Board (FASB) issued a new global revenue recognition guidance that replaces virtually all existing US GAAP guidance on contracts with customers and the related other assets and deferred costs. The guidance provides a five-step process for recognizing revenue that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires expanded qualitative and quantitative disclosures relating to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In July 2015, FASB approved the deferral of the effective date of this guidance by one year. As a result, this guidance will be effective for the Company beginning in fiscal year 2019, with an option to early adopt in fiscal year 2018. The new guidance is required to be applied retrospectively to each prior reporting period presented, or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application. The Company is currently evaluating the full impact of this new guidance on its consolidated financial statements, including selection of the transition method. However, assuming all other revenue recognition criteria have been met, it is likely that the new guidance would require the Company to recognize revenue and cost relating to distributor sales upon product delivery, subject to estimated allowance for distributor price adjustments and rights of return. In February 2016, the FASB issued the authoritative guidance on leases. The new guidance requires the recognition of assets and liabilities arising from lease transactions on the balance sheet and will also require significant additional disclosures about the amount, timing and uncertainty of cash flows from leases. Accordingly, a lessee will recognize a lease asset for its right to use the underlying asset and a lease liability for the corresponding lease obligation. The new guidance is effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, which for Xilinx would be the first quarter of fiscal year 2020. Early adoption is permitted. The new guidance must be adopted using a modified retrospective transition and provides for certain practical expedients. In addition, the transition will require application of the new guidance at the beginning of the earliest comparative period presented. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements. In March 2016, the FASB finalized its amendments in the new revenue recognition guidance on assessing whether an entity is a principal or an agent in a revenue transaction. The amendments clarify how an entity should identify the unit of accounting for the principal versus agent evaluation, and how it should apply the control principle to certain types of arrangements, such as service transactions, by explaining what a principal controls before the specified good or service is transferred to the customer. The FASB also addressed how an entity acting as a principal would determine its transaction price when it does not know the price charged to its customer for its goods or services by an intermediary. The amendments have the same effective date and transition requirements as the new revenue recognition guidance, which for Xilinx would be the beginning of fiscal year 2019. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements. In April 2016, the FASB finalized amendments in the new revenue recognition guidance on identifying performance obligations and accounting for licenses of intellectual property. The amendments address implementation issues that were raised by stakeholders and discussed by the Revenue Recognition Transition Resource Group (TRG). The amendments have the same effective date and transition requirements as the new revenue recognition guidance, which for Xilinx would be the beginning of fiscal year 2019. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements. In May 2016, the FASB finalized amendments in the new revenue recognition guidance on collectability, noncash consideration, presentation of sales tax, and transition. The amendments are intended to address implementation issues that were raised by stakeholders and discussed by TRG, and provide additional practical expedients. The amendments have the same effective date and transition requirements as the new revenue recognition guidance, which for Xilinx would be the beginning of fiscal year 2019. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements. In June 2016, the FASB issued the authoritative guidance which introduces new guidance for the accounting for credit losses on instruments for both financial services and non-financial services entities. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new guidance will be effective for public business entities in fiscal years beginning after December 15, 2019, including interim periods within those years, which for Xilinx would be the first quarter of fiscal year 2021. Early adoption is permitted. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements. In August 2016, the FASB issued authoritative guidance for cash flow classification. The new guidance is intended to reduce diversity in practice in how cash receipts and cash payments are classified in the statement of cash flows. The new guidance will be effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those years, which for Xilinx would be the first quarter of fiscal year 2019. Early adoption is permitted. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements.
