Temporary Equity Redeemable Noncontrolling Interests [Abstract]
Temporary Equity Redeemable Noncontrolling Interests [Text Block]	10. REDEEMABLE NONCONTROLLING INTERESTS The holders of equity interests in certain of the Company’s subsidiaries have rights (“Put Rights”) that may be exercised on varying dates causing the Company to purchase their equity interests beginning in fiscal 2012 through fiscal 2018. The Put Rights, all of which relate either to common shares or membership interests in limited liability companies, provide that the cash consideration to be paid for their equity interests (the “Redemption Amount”) be at fair value or at a formula that management intended to reasonably approximate fair value based solely on a multiple of future earnings over a measurement period. As of April 30, 2011, management’s estimate of the aggregate Redemption Amount of all Put Rights that the Company would be required to pay is approximately $54 million. The actual Redemption Amount will likely be different. The aggregate Redemption Amount of all Put Rights was determined using probability adjusted internal estimates of future earnings of the Company’s subsidiaries with Put Rights while considering the earliest exercise date, the measurement period and any applicable fair value adjustments. The portion of the estimated Redemption Amount as of April 30, 2011 redeemable at fair value is approximately $31 million and the portion redeemable based solely on a multiple of future earnings is approximately $23 million. The portion of periodic adjustments to the Redemption Amount based on fair value, if any, will have no effect on net income per share attributable to HEICO shareholders whereas the portion of periodic adjustments to the carrying amount of redeemable noncontrolling interests based solely on a multiple of future earnings in excess of fair value, if any, will affect net income per share attributable to HEICO shareholders. As discussed in Note 2, Acquisitions, the Company entered into an agreement to acquire an 80.1% interest in a subsidiary by the FSG in December 2010. As part of the agreement, the Company has the right to purchase the noncontrolling interests over a two-year period beginning in fiscal 2015, or sooner under certain conditions, and the noncontrolling interest holders have the right to cause the Company to purchase the same equity interests over the same period. The estimated amount of Put Rights related to the acquisition is included in the aggregate Redemption Amount above. In February 2011, the Company, through HEICO Aerospace, acquired an additional 8% equity interest in one of its subsidiaries, which increased the Company’s ownership interest to 80%. In April 2011, the Company, through HEICO Electronic, acquired an additional 2.6% equity interest in one of its subsidiaries, which increased the Company’s ownership interest to 95.9%. The purchase prices of the redeemable noncontrolling interests acquired during the second quarter of fiscal 2011 were paid using cash provided by operating activities.
