Accounting Policies [Abstract]

Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of HEICO Corporation and its subsidiaries (collectively, “HEICO,” or the “Company”) have been prepared in conformity with accounting principles generally accepted in the United States of America for interim financial information and in accordance with the instructions to Form 10-Q. Therefore, the condensed consolidated financial statements do not include all information and footnotes normally included in annual consolidated financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended October 31, 2011. The October 31, 2011 Condensed Consolidated Balance Sheet has been derived from the Company’s audited consolidated financial statements. In the opinion of management, the unaudited condensed consolidated financial statements contain all adjustments (consisting principally of normal recurring accruals) necessary for a fair presentation of the condensed consolidated balance sheets, statements of operations and statements of cash flows for such interim periods presented. The results of operations for the three months ended January 31, 2012 are not necessarily indicative of the results which may be expected for the entire fiscal year.

New Accounting Pronouncements and Changes In Accounting Principles [Text Block]

New Accounting Pronouncements

In January 2010, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2010-06, “Improving Disclosures About Fair Value Measurements,” which requires additional disclosures regarding transfers in and out of Level 1 and Level 2 fair value measurements and more detailed information of activity in Level 3 fair value measurements. The Company adopted ASU 2010-06 as of the beginning of fiscal 2010, except the additional Level 3 disclosures, which were adopted in the first quarter of fiscal 2012. ASU 2010-06 affects financial statement disclosures only and the Company will make the required additional disclosures as applicable.

In June 2011, the FASB issued ASU 2011-05, “Presentation of Comprehensive Income,” which requires the presentation of total comprehensive income, the components of net income and the components of other comprehensive income in either a single continuous statement of comprehensive income or in two separate, but consecutive statements. ASU 2011-05 eliminates the option to present other comprehensive income and its components in the statement of shareholders’ equity. ASU 2011-05 must be applied retroactively and is effective for fiscal years and interim periods within those years beginning after December 15, 2011, or in the first quarter of fiscal 2013 for HEICO. The Company is currently evaluating which presentation option it will elect, but the adoption of these provisions will have no effect on its results of operations, financial position or cash flows.

In September 2011, the FASB issued ASU 2011-08, “Testing Goodwill for Impairment,” which is intended to reduce complexity and costs by permitting an entity the option to perform a qualitative evaluation about the likelihood of goodwill impairment in order to determine whether it should calculate the fair value of a reporting unit. The update also improves previous guidance by expanding upon the examples of events and circumstances that an entity should consider between annual impairment tests in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. ASU 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, or in fiscal 2013 for HEICO’s annual impairment test. The adoption of this guidance is not expected to have a material impact on the Company’s results of operations, financial position or cash flows.
