Temporary Equity Disclosure [Abstract] |
Temporary Equity Redeemable Noncontrolling Interests [Text Block] | 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 through fiscal 2022. 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 July 31, 2013, management’s estimate of the aggregate Redemption Amount of all Put Rights that the Company would be required to pay is approximately $52 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 July 31, 2013 redeemable at fair value is approximately $42 million and the portion redeemable based solely on a multiple of future earnings is approximately $10 million. Adjustments to Redemption Amounts based on fair value will have no affect 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 that reflect a redemption amount in excess of fair value will affect net income per share attributable to HEICO shareholders. In December 2012, the Company, through its HEICO Aerospace Holdings Corp. ("HEICO Aerospace") subsidiary, acquired the remaining 13.3% interest in one of its subsidiaries. The purchase price of the redeemable noncontrolling interest acquired was paid using proceeds from the Company's revolving credit facility.
