Nature Of Operations Basis Of Presentation And Recently Issued Accounting Pronouncements [Abstract]
Nature of Operations	Nature of Operations Diodes Incorporated, together with its subsidiaries (collectively, the “Company,” “we” or “our”), is a leading global manufacturer and supplier of high-quality, application specific standard products within the broad discrete, logic and analog semiconductor markets, serving the consumer electronics, computing, communications, industrial and automotive markets throughout Asia, North America and Europe.
Basis of Presentation	Basis of Presentation The condensed consolidated financial data at December 31, 2014 is derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014 filed on March 2, 2015 (“Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, operating results and cash flows in conformity with GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in our Form 10-K. All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the operating results for the period presented have been included in the interim period. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2015. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates taking into consideration discrete items occurring in a quarter. Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted. Certain prior year’s balances have been reclassified to conform to the current financial statement presentation.
Business Combinations	Business Combinations During the normal course of business the Company makes acquisitions. In the event that an individual acquisition (or an aggregate of acquisitions) is material, appropriate disclosure of such acquisition activity is provided
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements The Financial Accounting Standards Board (“FASB”) issued the following Accounting Standards Updates (“ASU”) which could have potential impact to the Company’s financial statements: ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). This standard is based on the principle that revenue is recognized to depict the transfer of 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. This standard also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. This standard is effective date in the first quarter of 2018. Under this proposal, early adoption is permitted as of the original effective time period of first quarter of 2017 and requires either a retrospective or a modified retrospective approach to adoption. We have not yet selected a transition method and are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures. ASU No. 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Cost. This standard requires that costs associated with the issuance of debt previously recorded as deferred assets on the balance sheet now be reported as a direct reduction of the related debt balance. This standard is effective for interim and annual periods beginning January 1, 2016, but early adoption is permitted. We plan to adopt this standard in the first quarter of 2016. Upon adoption, this standard will be applied retrospectively to all prior periods presented. This standard will have no impact on the consolidated statements of operations and will have an immaterial impact from the reclassifications on our consolidated balance sheets. ASU No. 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”). This standard requires in scope inventory to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using last-in, first-out (“LIFO”) or the retail inventory method. The amendments do not apply to inventory that is measured using LIFO or the retail inventory method. The amendments apply to all other inventory, which includes inventory that is measured using first-in, first-out (“FIFO”) or average cost. The standard is effective for public business entities for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years and requires prospective application, with earlier application permitted as of the beginning of an interim or annual reporting period. We are evaluating the effect that ASU 2015-11 will have on our consolidated financial statements and related disclosures.
