Basis of Presentation [Abstract] |
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Microchip Technology Incorporated and its majority-owned subsidiaries (the Company). The Company owns 100% of the outstanding stock in all of its subsidiaries with the exception of its recent acquisition of ISSC Technologies Corporation (ISSC) as further discussed in Note 2. The noncontrolling interests in our net income from ISSC have been excluded from net income attributable to the Company in our condensed consolidated statements of income. All intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, pursuant to the rules and regulations of the Securities and Exchange Commission (the SEC). The information furnished herein reflects all adjustments which are, in the opinion of management, of a normal recurring nature and necessary for a fair statement of the results for the interim periods reported. Certain information and footnote disclosures normally included in audited consolidated financial statements have been condensed or omitted pursuant to such SEC rules and regulations. It is suggested that these condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended March 31, 2014. The results of operations for the six months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2015 or for any other period. As further discussed in Note 2, on July 17, 2014, the Company completed its acquisition of a controlling interest in ISSC and the Company's second quarter fiscal 2015 financial results include ISSC's results beginning as of the acquisition date.
