General Policies [Abstract]

Significant Accounting Policies [Text Block]

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business

HEICO Corporation, through its principal subsidiaries HEICO Aerospace Holdings Corp. ("HEICO Aerospace") and HEICO Electronic Technologies Corp. ("HEICO Electronic") and their subsidiaries (collectively, the "Company"), is principally engaged in the design, manufacture and sale of aerospace, defense and electronic related products and services throughout the United States and internationally. The Company's customer base is primarily the aviation, defense, space, medical, telecommunication and electronic industries.

Basis of Presentation

The consolidated financial statements include the accounts of HEICO Corporation and its subsidiaries, all of which are wholly-owned except for HEICO Aerospace, which is 20%-owned by Lufthansa Technik AG, the technical services subsidiary of Lufthansa German Airlines. In addition, HEICO Aerospace consolidates three subsidiaries which are 72%, 80%, and 82.3% owned, respectively, and a joint venture formed in March 2001, which is 16% owned by American Airlines' parent company, AMR Corporation. Also, HEICO Electronic consolidates three subsidiaries, which are 80%, 93.3% and 82.5% owned, respectively (see Note 12, Redeemable Noncontrolling Interests). All significant intercompany balances and transactions are eliminated.

Stock Split

In March 2010, the Company's Board of Directors declared a 5-for-4 stock split on both classes of the Company's common stock. The stock split was effected as of April 27, 2010 in the form of a 25% stock dividend distributed to shareholders of record as of April 16, 2010. All applicable share and per share information has been adjusted retrospectively to give effect to the 5-for-4 stock split.

Use of Estimates and Assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

For purposes of the consolidated financial statements, the Company considers all highly liquid investments such as U.S. Treasury bills and money market funds with an original maturity of three months or less to be cash equivalents.

Accounts Receivable

Accounts receivable consist of amounts billed and currently due from customers and unbilled costs and estimated earnings related to revenue from certain fixed price contracts recognized on the percentage-of-completion method that have been recognized for accounting purposes, but not yet billed to customers. The valuation of accounts receivable requires that the Company set up an allowance for estimated uncollectible accounts and record a corresponding charge to bad debt expense. The Company estimates uncollectible receivables based on such factors as its prior experience, its appraisal of a customer's ability to pay, age of receivables outstanding and economic conditions within and outside of the aviation, defense, space, medical, telecommunication and electronic industries.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of temporary cash investments and trade accounts receivable. The Company places its temporary cash investments with high credit quality financial institutions and limits the amount of credit exposure to any one financial institution. Concentrations of credit risk with respect to trade receivables are limited due to the large number of customers comprising the Company's customer base and their dispersion across many different geographical regions. The Company performs ongoing credit evaluations of its customers, but does not generally require collateral to support customer receivables.

Inventory

Inventory is stated at the lower of cost or market, with cost being determined on the first-in, first-out or the average cost basis. Losses, if any, are recognized fully in the period when identified.

The Company periodically evaluates the carrying value of inventory, giving consideration to factors such as its physical condition, sales patterns and expected future demand in order to estimate the amount necessary to write down its slow moving, obsolete or damaged inventory. These estimates could vary significantly from actual amounts based upon future economic conditions, customer inventory levels or competitive factors that were not foreseen or did not exist when the estimated write-downs were made.

In accordance with industry practice, all inventories are classified as a current asset including portions with long production cycles, some of which may not be realized within one year.

Property, Plant and Equipment

Property, plant and equipment is recorded at cost. Depreciation and amortization is generally provided on the straight-line method over the estimated useful lives of the various assets. The Company's property, plant and equipment is depreciated over the following estimated useful lives:

Buildings and improvements	15 to 40 years
Leasehold improvements	2 to 20 years
Machinery and equipment	3 to 10 years
Tooling	2 to 5 years

The costs of major additions and improvements are capitalized. Leasehold improvements are amortized over the shorter of the leasehold improvement's useful life or the lease term. Repairs and maintenance are expensed as incurred. Upon disposition, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected within earnings.

Business Combinations

As further explained in New Accounting Pronouncements below, the Company adopted new accounting guidance for business combinations effective prospectively for acquisitions consummated on or after November 1, 2009 (the beginning of fiscal 2010). Under the new guidance, any contingent consideration is recognized as a liability at fair value as of the acquisition date with subsequent fair value adjustments recorded in operations. Acquisition costs are generally expensed as incurred. For acquisitions consummated prior to fiscal 2010, contingent consideration is accounted for as an additional cost of the respective acquired entity when paid and acquisition costs were capitalized as part of the purchase price.

The Company allocates the purchase price of acquired entities to the underlying tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values, with any excess recorded as goodwill. The operating results of acquired businesses are included in the Company's results of operations beginning as of their effective acquisition dates.

Goodwill and Other Intangible Assets

The Company tests goodwill for impairment annually as of October 31, or more frequently if events or changes in circumstances indicate that the carrying amount of goodwill may not be fully recoverable. The test requires the Company to compare the fair value of each of its reporting units to its carrying value to determine potential impairment. If the carrying value of a reporting unit exceeds its fair value, the implied fair value of that reporting unit's goodwill is to be calculated and an impairment loss is recognized in the amount by which the carrying value of the reporting unit's goodwill exceeds its implied fair value, if any.

The Company's intangible assets not subject to amortization consist principally of its trade names. The Company's intangible assets subject to amortization are amortized on the straight-line method over the following estimated useful lives:

Customer relationships	5 to 10 years
Intellectual property	6 to 15 years
Licenses	12 to 17 years
Non-compete agreements	2 to 7 years
Patents	5 to 19 years
Trade names	5 to 10 years

Amortization expense of intellectual property, licenses and patents is recorded as a component of cost of sales, and amortization expense of customer relationships, non-compete agreements and trade names is recorded as a component of selling, general and administrative expenses in the Company's Consolidated Statement of Operations. The Company tests each non-amortizing intangible asset for impairment annually as of October 31, or more frequently if events or changes in circumstances indicate that the asset might be impaired. To derive the fair value of its trade names, the Company utilizes an income approach. The Company also tests each amortizing intangible asset for impairment if events or circumstances indicate that the asset might be impaired. The test consists of determining whether the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the undiscounted future cash flows is less than the carrying amount of those assets, the Company recognizes an impairment loss based on the excess of the carrying amount over the fair value of the assets.

Investments

Investments are stated at fair value based on quoted market prices. Investments that are intended to be held for less than one year are included within prepaid expenses and other current assets in the Company's Consolidated Balance Sheets, while those intended to be held for longer than one year are classified within other assets. Unrealized gains or losses associated with available-for-sale securities are reported net of tax within other comprehensive income in shareholders' equity. Unrealized gains or losses associated with trading securities are recorded as a component of other income in the Company's Consolidated Statement of Operations.

Derivative Instruments

From time to time, the Company utilizes certain derivative instruments (e.g. interest rate swap agreements and foreign currency forward contracts) to hedge the variability of expected future cash flows of certain transactions. On an ongoing basis, the Company assesses whether derivative instruments used in hedging transactions are highly effective in offsetting changes in cash flows of the hedged items and therefore qualify as cash flow hedges. For a derivative instrument that qualifies as a cash flow hedge, the effective portion of changes in fair value of the derivative is deferred and recorded as a component of other comprehensive income until the hedged transaction occurs and is recognized in earnings. All other portions of changes in the fair value of a cash flow hedge are recognized in earnings immediately.

The Company has previously utilized interest rate swap agreements to manage interest expense related to its revolving credit facility. Interest rate risk associated with the Company's variable rate revolving credit facility is the potential increase in interest expense from an increase in interest rates. The Company did not enter into any interest rate swap agreements in fiscal 2010, 2009 or 2008.

During fiscal 2008, the Company entered into a one year foreign currency forward contract to mitigate foreign exchange risk at one of its foreign subsidiaries for transactions denominated in a currency other than its functional currency. The impact of this forward contract did not have a material effect on the Company's results of operations, financial position or cash flows in fiscal 2009 or 2008. The Company did not enter into any foreign currency forward contracts in fiscal 2010 or 2009.

Customer Rebates and Credits

The Company records accrued customer rebates and credits as a component of accrued expenses and other current liabilities in the Company's Consolidated Balance Sheets. These amounts generally relate to discounts negotiated with customers as part of certain sales contracts that are usually tied to sales volume thresholds. The Company accrues customer rebates and credits as a reduction within net sales as the revenue is recognized based on the estimated level of discount rate expected to be earned by each customer over the life of the contract period (generally one year). Accrued customer rebates and credits are monitored by management and discount levels are updated at least quarterly.

Product Warranties

Product warranty liabilities are estimated at the time of shipment and recorded as a component of accrued expenses and other current liabilities in the Company's Consolidated Balance Sheets. The amount recognized is based on historical claims experience.

Revenue Recognition

Revenue is recognized on an accrual basis, primarily upon the shipment of products and the rendering of services. Revenue earned from rendering services represented less than 10% of consolidated net sales for all periods presented. Revenue from certain fixed price contracts for which costs can be dependably estimated is recognized on the percentage-of-completion method, measured by the percentage of costs incurred to date to estimated total costs for each contract. The percentage of the Company's net

sales recognized under the percentage-of-completion method was approximately 2%, 1%, and 3% in fiscal 2010, 2009 and 2008, respectively. Contract costs include all direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation costs. Selling, general and administrative costs are charged to expense as incurred.

Revisions in cost estimates as contracts progress have the effect of increasing or decreasing profits in the period of revision. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Variations in actual labor performance, changes to estimated profitability, and final contract settlements may result in revisions to cost estimates and are recognized in income in the period in which the revisions are determined.

The asset, "costs and estimated earnings in excess of billings" on uncompleted percentage-of-completion contracts, included in accounts receivable, represents revenue recognized in excess of amounts billed. The liability, "billings in excess of costs and estimated earnings," included in accrued expenses and other current liabilities, represents billings in excess of revenue recognized on contracts accounted for under either the percentage-of-completion method or the completed-contract method. Billings are made based on the completion of certain milestones as provided for in the contracts.

For fixed price contracts in which costs cannot be dependably estimated, revenue is recognized on the completed-contract method. A contract is considered complete when all significant costs have been incurred or the item has been accepted by the customer. The aggregate effects of changes in estimates relating to long-term contracts did not have a material effect on net income from consolidated operations in fiscal 2010, 2009 or 2008.

Stock-Based Compensation

The Company records compensation expense associated with stock options in its Consolidated Statements of Operations based on the grant date fair value of those awards. The fair value of each stock option on the date of grant is estimated using the Black-Scholes pricing model based on certain valuation assumptions. Expected volatilities are based on the Company's historical stock prices over the contractual terms of the options and other factors. The risk-free interest rates used are based on the published U.S. Treasury yield curve in effect at the time of the grant for instruments with a similar life. The dividend yield reflects the Company's expected dividend yield at the date of grant. The expected life represents the period that the stock options are expected to be outstanding, taking into consideration the contractual terms of the options and employee historical exercise behavior. The Company generally recognizes stock option compensation expense ratably over the award's vesting period.

The Company calculates the amount of excess tax benefit that is available to offset future write-offs of deferred tax assets, or additional paid-in-capital pool ("APIC Pool") by tracking each stock option award granted after November 1, 1996 on an employee-by-employee basis and on a grant-by-grant basis to determine whether there is a tax benefit situation or tax deficiency situation for each such award. The Company then compares the fair value expense to the tax deduction received for each stock option grant and aggregates the benefits and deficiencies, which have the effect of increasing or decreasing, respectively, the APIC Pool. Should the amount of future tax deficiencies be greater than the available APIC Pool, the Company will record the excess as income tax expense in its Consolidated Statements of Operations. The excess tax benefit resulting from tax deductions in excess of the cumulative compensation expense recognized for stock options exercised is presented as a financing activity in the Company's Consolidated Statements of Cash Flows. All other tax benefits related to stock options have been presented as a component of operating activities.

Income Taxes

Income tax expense includes United States and foreign income taxes, plus the provision for United States taxes on undistributed earnings of foreign subsidiaries not deemed to be permanently invested. Deferred income taxes are provided on elements of income that are recognized for financial accounting purposes in periods different from periods recognized for income tax purposes.

The Company accounts for uncertainty in income taxes and evaluates tax positions utilizing a two-step process. The first step is to determine whether it is more-likely-than-not that a tax position will be sustained upon examination based on the technical merits of the position. The second step is to measure the benefit to be recorded from tax positions that meet the more-likely-than-not recognition threshold by determining the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement and recognizing that amount in the financial statements. As a result of adopting the provisions of the new guidance relating to the accounting for uncertainty in income taxes effective November 1, 2007, the Company recognized a cumulative effect adjustment that decreased retained earnings as of the beginning of fiscal 2008 by $639,000. The Company's policy is to recognize interest and penalties related to income tax matters as a component of income tax expense. Further information regarding income taxes can be found in Note 6, Income Taxes.

Noncontrolling Interests

Effective November 1, 2009, the Company adopted new accounting guidance that requires the recognition of certain noncontrolling interests (previously referred to as minority interests) as a separate component within equity in the consolidated balance sheet. It also requires the amount of consolidated net income attributable to the parent and the noncontrolling interests be clearly identified and presented within the consolidated statement of operations. The adoption of this new guidance (which is included in Accounting Standards Codification ("ASC") 810, "Consolidation") has affected the presentation of noncontrolling interests in the Company's consolidated financial statements on a retrospective basis. For example, under this guidance, "Net income from consolidated operations" is comparable to what was previously presented as "Income before minority interests" and "Net income attributable to HEICO" is comparable to what was previously presented as "Net income." Further, acquisitions of noncontrolling interests are considered a financing activity under the new accounting guidance and are no longer presented as an investing activity.

Effective November 1, 2009, the Company also adopted new accounting guidance that retrospectively affects the financial statement classification and measurement of redeemable noncontrolling interests. This guidance is included in ASC 480, "Distinguishing Liabilities from Equity." As further detailed in Note 12, Redeemable Noncontrolling Interests, the holders of equity interests in certain of the Company's subsidiaries have rights ("Put Rights") that require the Company to provide cash consideration for their equity interests (the "Redemption Amount") 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. The Put Rights are embedded in the shares owned by the noncontrolling interest holders and are not freestanding. Previously, the Company recorded such redeemable noncontrolling interests at historical cost plus an allocation of subsidiary earnings based on ownership interest, less dividends paid to the noncontrolling interest holders. Effective November 1, 2009, the Company adjusted its redeemable noncontrolling interests in accordance with this new accounting guidance to the higher of their carrying cost or management's estimate of the Redemption Amount with a corresponding decrease to retained earnings and classified such interests outside of permanent equity. Under this guidance, subsequent adjustments to the carrying amount of redeemable noncontrolling interests to reflect any changes in the Redemption Amount at the end of each reporting period will be recorded in the same manner. Such adjustments to Redemption Amounts based on fair value 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 that reflect a redemption amount in excess of fair value will effect net income per share attributable to HEICO shareholders under the two-class method.

As a result of adopting the new accounting guidance for noncontrolling interests and redeemable noncontrolling interests, the Company (i) reclassified approximately $78 million from temporary equity (previously labeled as "Minority interests in consolidated subsidiaries") to permanent equity (labeled as "Noncontrolling interests") pertaining to noncontrolling interests that do not contain a redemption feature; and (ii) renamed temporary equity as "Redeemable noncontrolling interests" and recorded an approximately $45 million increase to redeemable noncontrolling interests with a corresponding decrease to retained earnings in the Company's Consolidated Balance Sheet. The resulting $57 million of redeemable noncontrolling interests as of November 1, 2009 represents management's estimate of the aggregate Redemption Amount of all Put Rights that the Company would be required to pay of which approximately $25 million is redeemable at fair value and approximately $32 million is redeemable based solely on a multiple of future earnings. The actual Redemption Amount will likely be different. See Note 12, Redeemable Noncontrolling Interests, for additional information as well as the Company's Consolidated Statements of Shareholders' Equity and Comprehensive Income, which have been retrospectively adjusted.

Net Income per Share Attributable to HEICO Shareholders

Basic net income per share attributable to HEICO shareholders is computed by dividing net income attributable to HEICO by the weighted average number of common shares outstanding during the period. Diluted net income per share attributable to HEICO shareholders is computed by dividing net income attributable to HEICO by the weighted average number of common shares outstanding during the period plus potentially dilutive common shares arising from the assumed exercise of stock options, if dilutive. The dilutive impact of potentially dilutive common shares is determined by applying the treasury stock method.

As further detailed in "Noncontrolling Interests" above, 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 are deducted from net income attributable to HEICO for purposes of determining net income per share attributable to HEICO shareholders under the two-class method (see Note 13, Net Income per Share Attributable to HEICO Shareholders).

Foreign Currency Translation

All assets and liabilities of foreign subsidiaries that do not utilize the United States dollar as its functional currency are translated at period-end exchange rates, while revenue and expenses are translated using average exchange rates for the period. Unrealized translation gains or losses are reported as foreign currency translation adjustments through other comprehensive income in shareholders' equity.

Contingencies

Losses for contingencies such as product warranties, litigation and environmental matters are recognized in income when they are probable and can be reasonably estimated. Gain contingencies are not recognized in income until they have been realized.

New Accounting Pronouncements

As discussed within "Noncontrolling Interests" above, the Company adopted new guidance related to the recognition, measurement and classification of noncontrolling interests.

In September 2006, the Financial Accounting Standards Board ("FASB") issued new guidance which defines fair value, establishes a framework for measuring fair value, and requires expanded disclosures about fair value measurements. This guidance is included in ASC 820, "Fair Value Measurements and Disclosures." In February 2008, the FASB issued additional guidance which delayed the effective date by one year for nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis. These nonfinancial assets and liabilities include items such as goodwill, other intangible assets, and property, plant and equipment that are measured at fair value resulting from impairment, if deemed necessary. The provisions of this guidance related to nonfinancial assets and liabilities were adopted by the Company on a prospective basis as of the beginning of fiscal 2010, or November 1, 2009. The adoption did not have a material effect on the Company's results of operations, financial position or cash flows.

In December 2007, the FASB issued new guidance for business combinations that retains the fundamental requirements of previous guidance that the acquisition method of accounting (formerly the "purchase accounting" method) be used for all business combinations and for an acquirer to be identified for each business combination. However, the new guidance changes the approach of applying the acquisition method in a number of significant areas, including that acquisition costs will generally be expensed as incurred; noncontrolling interests will be valued at fair value as of the acquisition date; in-process research and development will be recorded at fair value as an indefinite-lived intangible asset as of the acquisition date; restructuring costs associated with a business combination will generally be expensed subsequent to the acquisition date; and changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally will affect income tax expense. Further, any contingent consideration will be recognized as a liability at fair value as of the acquisition date with subsequent fair value adjustments recorded in operations. Contingent consideration was previously accounted for as an additional cost of the respective acquired entity when paid. The Company adopted the new guidance (which is included in ASC 805, "Business Combinations") on a prospective basis as of the beginning of fiscal 2010 for all business combinations consummated on or after November 1, 2009. The adoption did not have a material effect on the Company's results of operations, financial position or cash flows.

In January 2010, the FASB issued Accounting Standards Update ("ASU") 2010-06, "Improving Disclosures About Fair Value Measurements," which requires new 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 the second quarter of fiscal 2010, except the additional Level 3 disclosures, which are effective in fiscal years beginning after December 15, 2010, or as of fiscal 2012 for HEICO. The adoption did not have a material effect on the Company's results of operations, financial position or cash flows. The Company will make the additional Level 3 disclosures, if applicable, as of the date of adoption.

In December 2010, the FASB ratified Emerging Issues Task Force ("EITF") Issue 10-G, "Disclosure of Supplementary Pro Forma Information for Business Combinations." Under EITF Issue 10-G, supplemental pro forma information disclosures pertaining to acquisitions should be presented as if the business combination(s) occurred as of the beginning of the prior annual period when comparative financial statements are presented. EITF Issue 10-G is effective for business combinations consummated in periods beginning after December 15, 2010, or in the second quarter of fiscal 2011 for HEICO. Early adoption is permitted. The Company will make the required disclosures prospectively as of the date of the adoption for any material business combinations or series of immaterial business combinations that are material in the aggregate.

2. ACQUISITIONS

In November 2007, the Company, through an 80%-owned subsidiary of HEICO Aerospace, acquired all of the stock of a European company. The acquired company supplies aircraft parts for sale and exchange as well as repair management services to commercial and regional airlines, asset management companies and FAA overhaul and repair facilities.

In January 2008, the Company, through HEICO Aerospace, acquired certain assets and assumed certain liabilities of a U.S. company that designs and manufactures FAA-approved aircraft and engine parts primarily for the commercial aviation market. The Company has since combined the operations of the acquired entity within other subsidiaries of HEICO Aerospace.

In February 2008, the Company, through HEICO Aerospace, acquired an 80.1% interest in certain assets and certain liabilities of a U.S. company that is an FAA-approved repair station which specializes in avionics primarily for the commercial aviation market. The remaining noncontrolling interest is principally owned by certain members of the acquired company's management.

In May 2009, the Company, through HEICO Electronic, acquired 82.5% of the stock of VPT, Inc., a U.S. company that designs and provides power conversion products principally serving the defense, space and aviation industries. The remaining 17.5% continues to be owned by an existing VPT shareholder which is also a supplier to the acquired company. During the first year following the acquisition, VPT met certain earnings objectives which obligated the Company to pay additional purchase consideration of $1.3 million in the third quarter of fiscal 2010. In addition, subject to meeting certain earnings objectives during the second and third year following the acquisition, the Company may be obligated to pay additional purchase consideration of up to approximately $1.3 million in fiscal 2011 and $10.1 million in fiscal 2012.

In October 2009, the Company, through HEICO Electronic, acquired the business, assets and certain liabilities of the Seacom division of privately-held Dukane Corp. and formed a new subsidiary, Dukane Seacom, Inc. ("Seacom"). Seacom is a designer and manufacturer of underwater locator beacons used to locate aircraft cockpit voice recorders, flight data recorders, marine ship voyage recorders and various other devices which have been submerged under water. Subject to meeting certain earnings objectives during the first two years following the acquisition, the Company may be obligated to pay additional purchase consideration of up to approximately $11.7 million in aggregate. Based on the subsidiary's earnings in the first year following the acquisition, the Company accrued $4.1 million of additional purchase consideration as of October 31, 2010, which it expects to pay in fiscal 2011.

In February 2010, the Company, through HEICO Electronic, acquired substantially all of the assets and assumed certain liabilities of dB Control. dB control produces high-power devices used in both defense and commercial applications. As further detailed in Note 7, Fair Value Measurements, the Company may be obligated to pay contingent consideration of up to $2.0 million in fiscal 2013 should dB Control meet certain earnings objectives during the second and third years following the acquisition.

As part of the purchase agreements associated with certain prior year acquisitions, the Company may be obligated to pay additional purchase consideration based on the acquired subsidiary meeting certain earnings objectives following the acquisition. For acquisitions consummated prior to fiscal 2010, the Company accrues an estimate of additional purchase consideration when the earnings objectives are met. During fiscal 2010, the Company, through HEICO Electronic, paid $4.2 million of such additional purchase consideration of which $1.8 million was accrued as of October 31, 2009. During fiscal 2009, the Company, through HEICO Electronic, paid $3.8 million of such additional purchase consideration of which $2.2 million was accrued as of October 31, 2008. During fiscal 2008, the Company, through HEICO Aerospace and HEICO Electronic, paid $7.0 million and $4.7 million, respectively, of such additional purchase consideration, all of which was accrued as of October 31, 2007. The amounts paid in fiscal 2010, 2009 and 2008 were based on a multiple of each applicable subsidiary's earnings relative to target and were not contingent upon the former shareholders of the respective acquired entity remaining employed by the Company or providing future services to the Company. Accordingly, these amounts represent an additional cost of the respective entity recorded as additional goodwill. Information regarding additional contingent purchase consideration related to acquisitions prior to fiscal 2010 may be found in Note 16, Commitments and Contingencies.

The purchase price of each of the above referenced acquisitions was paid in cash using proceeds from the Company's revolving credit facility and is not material or significant to the Company's consolidated financial statements. The aggregate cost paid in cash for acquisitions, including additional purchase consideration payments, was $39.1 million, $59.8 million and $24.8 million in fiscal 2010, 2009 and 2008, respectively. The allocation of the purchase price of each acquisition to the tangible and identifiable intangible assets acquired and liabilities assumed is based on their estimated fair values as of the date of acquisition. The Company determines the fair values of such assets and liabilities, generally in consultation with third-party valuation advisors. The excess of the purchase price over the estimated fair values is recorded as goodwill (see Note 17, Supplemental Disclosures of Cash Flow Information).

The operating results of the Company's fiscal 2010 acquisition were included in the Company's results of operations from the effective acquisition date. The amount of net sales and earnings of the 2010 acquisition included in the Consolidated Statements of Operations is not material. The following table presents unaudited pro forma financial information for fiscal 2009 as if the fiscal 2010 acquisition had occurred as of November 1, 2008 for purposes of the information presented for the year ended October 31, 2009. Had the fiscal 2010 acquisition been consummated as of November 1, 2009, net sales, net income from consolidated operations, net income attributable to HEICO, and basic and diluted net income per share attributable to HEICO shareholders on a pro forma basis for fiscal 2010 would not have been materially different than the reported amounts. The pro forma financial information is presented for comparative purposes only and is not necessarily indicative of the results of operations that actually would have been achieved if the acquisition had taken place as of November 1, 2008. The unaudited pro forma financial information includes adjustments to historical amounts such as additional amortization expense related to intangible assets acquired and increased interest expense associated with borrowings to finance the acquisition.

The increase in accrued employee compensation and related payroll taxes as of October 31, 2010 compared to October 31, 2009 reflects a higher level of accrued performance awards based on the improved consolidated operating results.

The total customer rebates and credits deducted within net sales for the fiscal years ended October 31, 2010, 2009 and 2008 were $8,866,000, $8,315,000 and $10,249,000, respectively.

Other Long-Term Assets and Liabilities

The Company provides eligible employees, officers and directors of the Company the opportunity to voluntarily defer base salary, bonus payments, commissions, long-term incentive awards and directors fees, as applicable, on a pre-tax basis through the HEICO Corporation Leadership Compensation Plan ("LCP"), a nonqualified deferred compensation plan that conforms to Section 409A of the Internal Revenue Code. The Company matches 50% of the first 6% of base salary deferred by each participant. In fiscal 2008, the LCP was amended principally to allow director

fees that would otherwise be payable in Company common stock to be deferred into the Plan, and, when distributed, amounts would be distributable in actual shares of Company common stock. During fiscal 2009, the LCP was amended to comply with the final Section 409A regulations issued by the Internal Revenue Service, which became effective January 1, 2009. Further, while the Company has no obligation to do so, the LCP also provides the Company the opportunity to make discretionary contributions. The Company's matching contributions and any discretionary contributions are subject to vesting and forfeiture provisions set forth in the LCP. Company contributions to the Plan charged to income in fiscal 2010, 2009 and 2008 totaled $2,862,000, $2,195,000 and $2,075,000, respectively. The aggregate liabilities of the LCP were $22,223,000 and $15,552,000 as of October 31, 2010 and 2009, respectively, and are classified within other long-term liabilities in the Company's Consolidated Balance Sheets. The assets of the LCP, totaling $22,604,000 and $15,811,000 as of October 31, 2010 and 2009, respectively, are classified within other assets and principally represent cash surrender values of life insurance policies that are held within an irrevocable trust that may be used to satisfy the obligations under the LCP.

Other long-term liabilities also includes deferred compensation of $4,283,000 and $3,953,000 as of October 31, 2010 and 2009, respectively, principally related to elective deferrals of salary and bonuses under a Company sponsored non-qualified deferred compensation plan available to selected employees. The Company makes no contributions to this plan. The assets of this plan, which equaled the deferred compensation liability as of October 31, 2010 and 2009, respectively, are held within an irrevocable trust and classified within other assets in the Company's Consolidated Balance Sheets. Additional information regarding the assets of this deferred compensation plan and the LCP may be found in Note 7, Fair Value Measurements.

4. GOODWILL AND OTHER INTANGIBLE ASSETS

The Company has two operating segments: the Flight Support Group ("FSG") and the Electronic Technologies Group ("ETG"). Changes in the carrying amount of goodwill during fiscal 2010 and 2009 by operating segment are as follows:

	Segment				Consolidated
	FSG		ETG		Totals
Balances as of October 31, 2008	$	181,126,000	$	142,267,000	$	323,393,000
Goodwill acquired		6,444,000		29,269,000		35,713,000

Goodwill acquired		—		12,920,000		12,920,000
Adjustments to goodwill		—		1,960,000		1,960,000
Accrued additional purchase consideration		—		4,104,000		4,104,000

Balances as of October 31, 2010	$	188,459,000	$	196,557,000	$	385,016,000

The goodwill acquired during fiscal 2010 relates to the current year acquisition described in Note 2, Acquisitions. The goodwill acquired during fiscal 2009 relates to the prior year acquisitions described in Note 2, Acquisitions, as well as acquisitions of redeemable noncontrolling interests described in Note 12, Redeemable Noncontrolling Interests. The amounts represent the residual value after the allocation of the total consideration to the tangible and identifiable intangible assets acquired and liabilities assumed (inclusive of contingent consideration for the fiscal 2010 acquisition). The adjustments to goodwill during fiscal 2010 and 2009 principally represent additional purchase consideration paid relating to prior year acquisitions for which the earnings objectives were met in fiscal 2010 and 2009, respectively. The accrued additional purchase consideration recognized in fiscal 2010 and 2009 is the result of certain subsidiaries of the ETG meeting certain earnings objectives in those respective fiscal years. See Note 2 and Note 16, Commitments and Contingencies, for additional information regarding additional contingent purchase consideration. The foreign currency translation adjustment reflects unrealized translation gains on the goodwill recognized in connection with foreign subsidiaries. Foreign currency translation adjustments are included in other comprehensive income in the Company's Consolidated Statements of Shareholders' Equity and Comprehensive Income. The Company estimates that approximately $19 million and $25 million of the goodwill recognized in fiscal 2010 and 2009, respectively, will be deductible for income tax purposes. Based on the annual test for goodwill impairment as of October 31, 2010, the Company determined there is no impairment of its goodwill as the fair value of each of the Company's reporting units significantly exceeded their carrying value.

The increase in the gross carrying amount of customer relationships, intellectual property and non-amortizing trade names as of October 31, 2010 compared to October 31, 2009 principally relates to such intangible assets recognized in connection with an acquisition made during the second quarter of fiscal 2010 (see Note 2, Acquisitions, and Note 17, Supplemental Disclosures of Cash Flow Information). The increase in the gross carrying amount of customer relationships recognized in connection with the fiscal 2010 acquisition was partially offset by the write-off of certain such fully amortized intangible assets and a write-down to fair value of certain other such intangible assets. During fiscal 2010 and 2009, the Company recognized impairment losses of approximately $1.1 million and $.2 million, respectively, from the write-down of certain customer relationships and $.3 million and $.1 million, respectively, from the write-down of trade names, within the ETG to their estimated fair values, due to reductions in future cash flows associated with such intangible assets. The impairment losses were recorded as a component of selling, general and administrative expenses in the Company's Consolidated Statement of Operations.

The weighted average amortization period of the customer relationships and intellectual property acquired during fiscal 2010 is eight years. Based on the final purchase price allocations during the allocation period for certain fiscal 2009 acquisitions, the weighted average amortization period of the customer relationships and intellectual property acquired in fiscal 2009 is approximately eight years and seven years, respectively. The weighted average amortization period of the finite-lived trade names and non-compete agreements acquired during fiscal 2009 is approximately five years and two years, respectively.

Amortization expense of other intangible assets was $6,795,000, $4,499,000 and $5,156,000 for the fiscal years ended October 31, 2010, 2009 and 2008, respectively. Amortization expense for each of the next five fiscal years and thereafter is estimated to be $6,100,000 in fiscal 2011, $5,396,000 in fiscal 2012, $4,936,000 in fiscal 2013, $4,639,000 in fiscal 2014, $3,495,000 in fiscal 2015 and $7,810,000 thereafter.

Borrowings under revolving credit facility	$	14,000,000		$	55,000,000
Notes payable, capital leases and equipment loans		221,000			431,000

Less: Current maturities of long-term debt		(148,000	)		(237,000	)
	$	14,073,000		$	55,194,000

The aggregate balance of long-term debt will mature within the next three fiscal years with $148,000 in fiscal 2011,$52,000 in fiscal 2012 and $14,021,000 in fiscal 2013.

Revolving Credit Facility

In May 2008, the Company amended its revolving credit facility by entering into a $300 million Second Amended and Restated Revolving Credit Agreement ("Credit Facility") with a bank syndicate, which matures in May 2013. Under certain circumstances, the maturity may be extended for two one-year periods. The Credit Facility also includes a feature that will allow the Company to increase the Credit Facility, at its option, up to $500 million through increased commitments from existing lenders or the addition of new lenders. The Credit Facility may be used for working capital and general corporate needs of the Company, including letters of credit, capital expenditures and to finance acquisitions. Advances under the Credit Facility accrue interest at the Company's choice of the "Base Rate" or the London Interbank Offered Rate ("LIBOR") plus applicable margins (based on the Company's ratio of total funded debt to earnings before interest, taxes, depreciation and amortization, noncontrolling interest and non-cash charges, or "leverage ratio"). The Base Rate is the higher of (i) the Prime Rate or (ii) the Federal Funds rate plus .50%. The applicable margins for LIBOR-based borrowings range from .625% to 2.25%. A fee is charged on the amount of the unused commitment ranging from .125% to .35% (depending on the Company's leverage ratio). The Credit Facility also includes a $50 million sublimit for borrowings made in euros, a $30 million sublimit for letters of credit and a $20 million swingline sublimit. The Credit Facility is unsecured and contains covenants that require, among other things, the maintenance of the leverage ratio, a senior leverage ratio and a fixed charge coverage ratio. In the event the Company's leverage ratio exceeds a specified level, the Credit Facility would become secured by the capital stock owned in substantially all of the Company's subsidiaries.

As of October 31, 2010 and 2009, the Company had a total of $14 million and $55 million, respectively, borrowed under its revolving credit facility at a weighted average interest rate of .9% as of each period. The amounts were primarily borrowed to fund acquisitions (see Note 2, Acquisitions) as well as for working capital and general corporate purposes. The revolving credit facility contains both financial and non-financial covenants. As of October 31, 2010, the Company was in compliance with all such covenants.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company believes that it is more likely than not that it will generate sufficient future taxable income to utilize all of its deferred tax assets and has therefore not recorded a valuation allowance on any such asset. Significant components of the Company's deferred tax assets and liabilities are as follows:

	As of October 31,
	2010			2009
Deferred tax assets:
Inventories	$	14,196,000		$	13,123,000

Net deferred tax liability	$	(26,401,000	)	$	(24,669,000	)

As of October 31, 2010 and 2009, the Company's liability for gross unrecognized tax benefits related to uncertain tax positions was $2,306,000 and $3,328,000, respectively, of which $1,927,000 and $2,859,000, respectively, would decrease the Company's income tax expense and effective income tax rate if the tax benefits were recognized.

A reconciliation of the activity related to the liability for gross unrecognized tax benefits during the fiscal years ended October 31, 2010 and 2009 is as follows:

	Year ended October 31,
	2010			2009
Balances as of beginning of year	$	3,328,000		$	5,742,000
Increases related to prior year tax positions		46,000			91,000
Decreases related to prior year tax positions		(1,229,000	)		(3,562,000	)
Increases related to current year tax positions		551,000			1,234,000
Settlements		(31,000	)		(211,000	)
Lapse of statutes of limitations		(359,000	)		34,000
Balances as of end of year	$	2,306,000		$	3,328,000

The Company's net liability for unrecognized tax benefits was $2,252,000 as of October 31, 2010, including $238,000 of interest and $170,000 of penalties and net of $462,000 in related deferred tax assets. During the fiscal year ended October 31, 2010, the Company accrued interest of $62,000 and penalties of $22,000 related to the unrecognized tax benefits noted above.

The $1,022,000 decrease in the liability during fiscal 2010 was principally related to the finalization of a study of qualifying research and development activities used to prepare the Company's fiscal 2009 U.S. federal and state income tax returns and the settlement of the California Franchise Tax Board examination of the income tax credit claimed for qualified research and development activities on the Company's state of California filings for fiscal years 2001 through 2005. The decrease in the liability reduced the Company's income tax expense by $932,000.

The $2,414,000 decrease in the liability during fiscal 2009 was principally related to the release of liabilities for tax positions for which the uncertainty was only related to the timing of such tax benefits and the effect of a favorable settlement reached with the IRS during fiscal 2009, partially offset by increases related to current year tax positions. During the IRS' examination of the income tax credits claimed by the Company in its U.S. federal filings for qualified research and development activities incurred for fiscal years 2002 through 2005, new information was obtained that supported an aggregate reduction of the liability for uncertain tax positions concerning research and development activities for fiscal years 2002 through 2008. As a result of the IRS settlement and associated liability adjustment, the Company recognized a tax benefit, which increased net income attributable to HEICO by approximately $1,225,000 for fiscal 2009. Further, during the second quarter of 2009, the Company filed an application with the IRS for an accounting methodology change that does not require the IRS' advanced approval. As this change removed the uncertainty surrounding certain tax positions that were related only to the timing of such tax benefits, the Company released the related liability, including interest, and deferred tax asset upon filing the application, which did not have a material effect on net income for the fiscal year 2009.

The Company files income tax returns in the United States ("U.S.") federal jurisdiction and in multiple state jurisdictions. The Company is also subject to income taxes in certain jurisdictions outside the U.S., none of which are individually material to the accompanying consolidated financial statements. Generally, the Company is no longer subject to U.S. federal or state examinations by tax authorities for fiscal years prior to 2006.

The total amount of unrecognized tax benefits can change due to audit settlements, tax examination activities, lapse of applicable statutes of limitations and the recognition and measurement criteria under the guidance related to accounting for uncertainty in income taxes. The Company is unable to estimate what this change could be within the next twelve months, but does not believe it would be material to its consolidated financial statements.

FAIR VALUE MEASUREMENTS

Fair Value Measures and Disclosuers [Abstract]

Fair Value Disclosures [Text Block]

7. FAIR VALUE MEASUREMENTS

The Company performs its fair value measurements according to accounting guidance that defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance also establishes a three-level fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. An asset or liability's level is based on the lowest level of input that is significant to the fair value measurement. The guidance requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

Level 1 -

Quoted prices in active markets for identical assets or liabilities;

Level 2 -

Inputs, other than quoted prices included within Level 1, that are observable for the asset or liability either directly or indirectly; or

Level 3 -

Unobservable inputs for the asset or liability where there is little or no market data, requiring management to develop its own assumptions.

The following tables set forth by level within the fair value hierarchy the Company's assets and liabilities that were measured at fair value on a recurring basis as of October 31, 2010 and 2009:

The Company maintains two non-qualified deferred compensation plans. The assets of the HEICO Corporation Leadership Compensation Plan (the "LCP") principally represent cash surrender values of life insurance policies, which derive their fair values from investments in mutual funds that are managed by an insurance company and are classified within Level 2. Certain other assets of the LCP represent investments in HEICO common stock and money market funds that are classified within Level 1. The assets of the Company's other deferred compensation plan are principally invested in a life insurance policy that is classified within Level 2 and equity securities, mutual funds and money market funds that are classified within Level 1. The assets of both plans are held within irrevocable trusts and classified within other assets in the Company's Consolidated Balance Sheets. The related liabilities of the two deferred compensation plans are included within other long-term liabilities in the Company's Consolidated Balance Sheets and have an aggregate value of $26,506,000 as of October 31, 2010 and $19,505,000 as of October 31, 2009.

The Company did not have any transfers between Level 1 and Level 2 fair value measurements during fiscal 2010.

As part of the agreement to acquire a subsidiary by the ETG in the second quarter of fiscal 2010, the Company may be obligated to pay contingent consideration of up to $2.0 million in fiscal 2013 should the acquired entity meet certain earnings objectives during the second and third years following the acquisition. The $1,150,000 fair value of the contingent consideration as of the acquisition date was determined using a discounted cash flow model and probability adjusted internal estimates of the subsidiary's future earnings and is classified in Level 3. There have been no subsequent changes in the fair value of this contingent consideration as of October 31, 2010 and this obligation is included in other long-term liabilities in the Company's Consolidated Balance Sheet. Changes in the fair value of contingent consideration will be recorded in the Company's consolidated statements of operations.

The carrying amounts of cash and cash equivalents, accounts receivable, trade accounts payable and accrued expenses and other current liabilities approximate fair value as of October 31, 2010 due to the relatively short maturity of the respective instruments. The carrying value of long-term debt approximates fair value due to its variable interest rates.

During fiscal 2010 and 2009, certain intangible assets within the ETG were measured at fair value on a nonrecurring basis, resulting in the recognition of impairment losses aggregating $1.4 million and $.3 million, respectively (see Note 4, Goodwill and Other Intangible Assets). The fair value of each asset was determined using a discounted cash flow model and internal estimates of each asset's future cash flows.

The following table sets forth the fair values as of October 31 of the Company's nonfinancial assets and liabilities that were measured at fair value on a nonrecurring basis, all of which are classified in Level 3, and related impairment losses recognized during fiscal 2010 and 2009:

SHAREHOLDERS' EQUITY	Oct. 31, 2010
Stockholders' Equity Note [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	8. SHAREHOLDERS' EQUITY Preferred Stock Purchase Rights Plan The Company's Board of Directors adopted, as of November 2, 2003, a Shareholder Rights Agreement (the "2003 Plan"). Pursuant to the 2003 Plan, the Board declared a dividend of one preferred share purchase right for each outstanding share of Common Stock and Class A Common Stock (with the preferred share purchase rights collectively as the "Rights"). The Rights trade with the common stock and are not exercisable or transferable apart from the Common Stock and Class A Common Stock until after a person or group either acquires 15% or more of the outstanding common stock or commences or announces an intention to commence a tender offer for 15% or more of the outstanding common stock. Absent either of the aforementioned events transpiring, the Rights will expire as of the close of business on November 2, 2013. The Rights have certain anti-takeover effects and, therefore, will cause substantial dilution to a person or group who attempts to acquire the Company on terms not approved by the Company's Board of Directors or who acquires 15% or more of the outstanding common stock without approval of the Company's Board of Directors. The Rights should not interfere with any merger or other business combination approved by the Board since they may be redeemed by the Company at $.01 per Right at any time until the close of business on the tenth day after a person or group has obtained beneficial ownership of 15% or more of the outstanding common stock or until a person commences or announces an intention to commence a tender offer for 15% or more of the outstanding common stock. The 2003 Plan also contains a provision to help ensure a potential acquirer pays all shareholders a fair price for the Company. Common Stock and Class A Common Stock Each share of Common Stock is entitled to one vote per share. Each share of Class A Common Stock is entitled to a 1/10 vote per share. Holders of the Company's Common Stock and Class A Common Stock are entitled to receive when, as and if declared by the Board of Directors, dividends and other distributions payable in cash, property, stock or otherwise. In the event of liquidation, after payment of debts and other liabilities of the Company, and after making provision for the holders of preferred stock, if any, the remaining assets of the Company will be distributable ratably among the holders of all classes of common stock. Stock Split In March 2010, the Company's Board of Directors declared a 5-for-4 stock split on both classes of the Company's common stock. The stock split was effected as of April 27, 2010 in the form of a 25% stock dividend distributed to shareholders of record as of April 16, 2010. All applicable share and per share information has been adjusted retrospectively to give effect to the 5-for-4 stock split. Share Repurchases In accordance with the Company's share repurchase program, 242,170 shares of Class A Common Stock were repurchased at a total cost of $3.9 million and 230,625 shares of Common Stock were repurchased at a total cost of $4.2 million during the second quarter of 2009. In March 2009, the Company's Board of Directors approved an increase in the Company's share repurchase program by an aggregate 1,250,000 shares of either or both Class A Common Stock and Common Stock, bringing the total authorized for future purchase to 1,280,928 shares. During the first and second quarters of fiscal 2010, the Company repurchased an aggregate 17,577 shares of Common Stock at a total cost of $.6 million and an aggregate 2,613 shares of Class A Common Stock at a total cost of $.1 million. The transactions occurred as settlement for employee taxes due pertaining to exercises of non-qualified stock options and did not impact the number of shares authorized for future purchase under the Company's share repurchase program. The Company did not repurchase any shares of its common stock in fiscal 2008.

9. STOCK OPTIONS

The Company currently has two stock option plans, the 2002 Stock Option Plan ("2002 Plan") and the Non-Qualified Stock Option Plan, under which stock options may be granted. The Company's 1993 Stock Option Plan ("1993 Plan") terminated in March 2003 on the tenth anniversary of its effective date. No options may be granted under the 1993 Plan after such termination date; however, options outstanding as of the termination date may be exercised pursuant to their terms. In addition, the Company

granted stock options in fiscal 2002 to a former shareholder of an acquired business pursuant to an employment agreement entered into in connection with the acquisition in fiscal 1999. A total of 3,582,520 shares of the Company's stock are reserved for issuance to employees, directors, officers and consultants as of October 31, 2010, including 2,137,448 shares currently under option and 1,445,072 shares available for future grants. Options issued under the 2002 Plan may be designated as incentive stock options or non-qualified stock options. Incentive stock options are granted with an exercise price of not less than 100% of the fair market value of the Company's common stock as of date of grant (110% thereof in certain cases) and are exercisable in percentages specified as of the date of grant over a period up to ten years. Only employees are eligible to receive incentive stock options. Non-qualified stock options under the 2002 Plan may be immediately exercisable. In March 2008, the Company's shareholders approved two amendments to the 2002 Plan, which principally increased the number of shares available for issuance under the plan and now requires options be granted with an exercise price of no less than fair market value of the Company's common stock as of the date of the grant. The options granted pursuant to the 2002 Plan may be designated as Common Stock and/or Class A Common Stock in such proportions as shall be determined by the Board of Directors or the Stock Option Plan Committee at its sole discretion. Options granted under the Non-Qualified Stock Option Plan may be granted with an exercise price of no less than the fair market value of the Company's common stock as of the date of grant and are generally exercisable in four equal annual installments commencing one year from the date of grant. The stock options granted to a former shareholder of an acquired business were fully vested and transferable as of the grant date and expire ten years from the date of grant. The exercise price of such options was the fair market value as of the date of grant. Options under all stock option plans expire no later than ten years after the date of grant, unless extended by the Stock Option Plan Committee or the Board of Directors.

Information concerning stock option activity for each of the three fiscal years ended October 31 is as follows:

Net income attributable to HEICO for the fiscal years ended October 31, 2010, 2009 and 2008 includes compensation expense of $1,353,000, $181,000 and $142,000, respectively, and an income tax benefit of $516,000, $64,000 and $43,000, respectively, related to the Company's stock options. Substantially all of the stock option compensation expense was recorded as a component of selling, general and administrative expenses in the Company's Consolidated Statements of Operations. As of October 31, 2010, there was $9,131,000 of pre-tax unrecognized compensation expense related to nonvested stock options, which is expected to be recognized over a weighted average period of approximately 4.3 years. The total fair value of stock options that vested in 2010, 2009 and 2008 was $1,212,000, $14,000 and $408,000, respectively.

For the fiscal years ended October 31, 2010, 2009 and 2008, the excess tax benefit resulting from tax deductions in excess of the cumulative compensation cost recognized for stock options exercised was $669,000, $1,573,000 and $4,324,000, respectively, and is presented as a financing activity in the Company's Consolidated Statements of Cash Flows.

The weighted-average fair value of stock options granted during fiscal 2010 was $22.31 per share for Common Stock and $11.13 per share for Class A Common Stock. The weighted-average fair value of stock options granted during fiscal 2009 was $16.79 per share for Common Stock and $10.76 per share for Class A Common Stock. The Company did not grant any stock options in fiscal 2008. If there were a change in control of the Company, all of the unvested options outstanding as of October 31, 2010 would become immediately exercisable.

The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option-pricing model based on the following weighted average assumptions for the fiscal years ended October 31, 2010 and 2009:

	2010						2009

RETIREMENT PLANS	Oct. 31, 2010
Disclosure Compansation Related Costs, Retirement Benefits [Abstract]
Pension and Other Postretirement Benefits Disclosure [Text Block]	10. RETIREMENT PLANS The Company has a qualified defined contribution retirement plan (the "Plan") under which eligible employees of the Company and its participating subsidiaries may make Elective Deferral Contributions up to the limitations set forth in Section 402(g) of the Internal Revenue Code. The Company generally makes a 25% or 50% Employer Matching Contribution, as determined by the Board of Directors, based on a participant's Elective Deferral Contribution up to 6% of the participant's Compensation for the Elective Deferral Contribution period. The Employer Matching Contribution may be contributed to the Plan in the form of the Company's common stock or cash, as determined by the Company. The Company's match of a portion of a participant's contribution is invested in Company common stock and is based on the fair value of the shares as of the date of contribution. The Plan also provides that the Company may contribute to the Plan additional amounts in its common stock or cash at the discretion of the Board of Directors. Employee contributions can not be invested in Company common stock. Participants receive 100% vesting of employee contributions and cash dividends received on Company common stock. Vesting in Company contributions is based on a participant's number of years of vesting service. Contributions to the Plan charged to income in fiscal 2010, 2009 and 2008 totaled $20,000, $40,000 and $230,000, respectively. Company contributions are made with the use of forfeited shares within the Plan. As of October 31, 2010, the Plan held approximately 37,000 forfeited shares of Common Stock and 84,000 forfeited shares of Class A Common Stock, which are available to make future Company contributions. In 1991, the Company established a Directors Retirement Plan covering its then current directors. The net assets and expenses of this plan as of October 31, 2010, 2009 and 2008 were not material to the financial position of the Company. The projected benefit obligation of this plan was $409,000 and $441,000 as of October 31, 2010 and 2009, respectively, and is classified within other long-term liabilities in the Company's Consolidated Balance Sheets.

REDEEMABLE NONCONTROLLING INTERESTS	12 Months Ended
REDEEMABLE NONCONTROLLING INTERESTS	Oct. 31, 2010
Disclosure Noncontrolling Interest [Abstract]
Redeemable Non controlling Interests	12. 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 2011 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 October 31, 2010, management's estimate of the aggregate Redemption Amount of all Put Rights that the Company would be required to pay is approximately $55 million. The actual Redemption Amount will likely be different. The portion of the estimated Redemption Amount as of October 31, 2010 redeemable at fair value is approximately $25 million and the portion redeemable based solely on a multiple of future earnings is approximately $30 million. See Note 1, Summary of Significant Accounting Policies, for more information regarding how the Company accounts for its redeemable noncontrolling interests in accordance with new accounting guidance adopted as of the beginning of fiscal 2010 and the Company's Consolidated Statements of Shareholders' Equity and Comprehensive Income for a summary of changes in redeemable noncontrolling interests for fiscal 2010. Acquisitions of redeemable noncontrolling interests are treated as equity transactions under the new accounting guidance. During fiscal 2008 and 2009, the Company accounted for acquisitions of redeemable noncontrolling interests under the accounting guidance in effect at that time pertaining to step acquisitions. The excess of the purchase price paid over the carrying amount was allocated principally to goodwill under such guidance. The Company's Consolidated Statement of Shareholders' Equity and Comprehensive Income for fiscal 2008 and 2009 is presented on a retrospective basis to reflect the adoption of new accounting guidance as of November 1, 2009 pertaining to redeemable noncontrolling interests, which resulted in an increase to redeemable noncontrolling interests and a decrease to retained earnings. The subsequent acquisition of certain redeemable noncontrolling interests on a retrospective basis results in a reversal of any previously recorded decrease to retained earnings related to such redeemable noncontrolling interests recorded as part of the adoption of this new accounting guidance. The portion of adjustments to the redemption amount of redeemable noncontrolling interests determined to be in excess of fair value in fiscal 2010 was $102,000, which affects the calculation of basic and diluted net income per share attributable to HEICO shareholders under the two-class method. No portions of the adjustments to the redemption amount of redeemable noncontrolling interests were determined to be in excess of fair value in fiscal 2009 and 2008. See Note 13, Net Income per Share Attributable to HEICO Shareholders, for the computation of net income per share under the two-class method. A summary of the put and call rights associated with the redeemable noncontrolling interests in certain of the Company's subsidiaries and transactions involving redeemable noncontrolling interests during fiscal 2010, 2009 and 2008 is as follows: As part of the agreement to acquire an 80% interest in a subsidiary by the ETG in fiscal 2004, the noncontrolling interest holders currently have the right to cause the Company to purchase their interests over a five-year period and the Company has the right to purchase the noncontrolling interests over a five-year period beginning in fiscal 2015, or sooner under certain conditions. Pursuant to the purchase agreement related to the acquisition of an 85% interest in a subsidiary by the ETG in fiscal 2005, certain noncontrolling interest holders exercised their option during fiscal 2007 to cause the Company to purchase their aggregate 3% interest over a four-year period that ended in fiscal 2010. Pursuant to this same purchase agreement, certain other noncontrolling interest holders exercised their option during fiscal 2009 to cause the Company to purchase their aggregate 10.5% interest over a four-year period ending in fiscal 2012. Accordingly, the Company increased its ownership interest in the subsidiary by an aggregate 8.3% (or one-fourth of such applicable noncontrolling interest holders' aggregate interest in fiscal years 2007 through 2010) to 93.3% effective April 2010. The purchase prices of the acquired equity interests were paid using cash provided by operating activities. Further, the remaining noncontrolling interest holders currently have the right to cause the Company to purchase their aggregate 1.5% interest over a four-year period. Pursuant to the purchase agreement related to the acquisition of a 51% interest in a subsidiary by the FSG in fiscal 2006, the noncontrolling interest holders exercised their option during fiscal 2008 to cause the Company to purchase an aggregate 28% interest over a four-year period ending in fiscal 2011. Accordingly, the Company increased its ownership interest in the subsidiary by 7% (or one-fourth of such noncontrolling interest holders' aggregate interest) to 58% effective April 2008. The Company and the noncontrolling interest holders agreed to accelerate the purchase of 14% of these equity interests (7% from April 2009 and 7% from April 2010), which increased the Company's ownership interest to 72% effective December 2008. The remaining 7% interest is scheduled to be purchased in April 2011. Further, the Company has the right to purchase the remaining 21% of the equity interests of the subsidiary over a three-year period beginning in fiscal 2012, 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. As part of the agreement to acquire an 80% interest in a subsidiary by the FSG in fiscal 2006, the Company has the right to purchase the noncontrolling interests over a four-year period beginning in fiscal 2014, 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. As part of the agreement to acquire an 80.1% interest in a subsidiary by the FSG in fiscal 2008, the Company has the right to purchase the noncontrolling interests over a five-year period beginning in fiscal 2014, 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. In May 2010, the Company, through the FSG, acquired an additional 2.2% equity interest in the subsidiary, which increased the Company's ownership interest to 82.3%. The additional equity interest acquired was pursuant to an amendment to the original agreement which does not affect the put/call provisions pertaining to the remaining noncontrolling interests. During the first quarter of fiscal 2009, the Company, through HEICO Aerospace, acquired the remaining 10% equity interest in one of its subsidiaries, which increased the Company's ownership interest to 100% effective October 31, 2008. The purchase price of the acquired equity interest, which was accrued as of October 31, 2008, was paid using cash provided by operating activities. As part of an agreement to acquire an 82.5% interest in a subsidiary by the ETG in fiscal 2009, the Company has the right to purchase the noncontrolling interests beginning in fiscal 2014, or sooner under certain conditions, and the noncontrolling interest holder has the right to cause the Company to purchase the same equity interests over the same period. The purchase prices of the redeemable noncontrolling interests acquired in fiscal 2010 were paid using cash provided by operating activities. The purchase prices of the redeemable noncontrolling interests acquired in fiscal 2009 and 2008 were paid in cash using proceeds from the Company's revolving credit facility unless otherwise noted. The aggregate cost of the redeemable noncontrolling interests acquired was $.8 million, $11.3 million and $4.3 million in fiscal 2010, 2009 and 2008, respectively.

During the fourth quarter of fiscal 2010, the Company recorded impairment losses related to the write-down of certain intangible assets to their estimated fair values, which decreased net income attributable to HEICO by $713,000, or $.02 per diluted share, in aggregate.

During the first and second quarters of fiscal 2009, the Company reached a settlement with the Internal Revenue Service concerning the income tax credit claimed by the Company on its U.S. federal filings for qualified research and development activities incurred during fiscal years 2002 through 2005 as well as an aggregate reduction to the related liability for unrecognized tax benefits for fiscal years 2006 through 2008, which increased net income attributable to HEICO by approximately $1,225,000, or $.04 per diluted share.

Due to changes in the average number of common shares outstanding, net income per share for the full fiscal year may not equal the sum of the four individual quarters.

Commitments and Contingencies Disclosure [Text Block]

16. COMMITMENTS AND CONTINGENCIES

Lease Commitments

The Company leases certain property and equipment, including manufacturing facilities and office equipment under operating leases. Some of these leases provide the Company with the option after the initial lease term either to purchase the property at the then fair market value or renew the lease at the then fair rental value. Generally, management expects that leases will be renewed or replaced by other leases in the normal course of business.

Future minimum payments under non-cancelable operating leases for the next five fiscal years and thereafter are estimated to be as follows:

Year ending October 31,
2011	$	6,167,000
2012		5,542,000
2013		4,106,000
2014		2,318,000
2015		2,168,000
Thereafter		4,511,000
Total minimum lease commitments	$	24,812,000

Total rent expense charged to operations for operating leases in fiscal 2010, 2009 and 2008 amounted to $6,963,000, $6,274,000 and $6,074,000, respectively.

Guarantees

The Company has arranged for a standby letter of credit for $1.5 million to meet the security requirement of its insurance company for potential workers' compensation claims, which is supported by the Company's revolving credit facility.

Product Warranty

Changes in the Company's product warranty liability for fiscal 2010 and 2009 are as follows:

	Year ended October 31,
	2010			2009
Balances as of beginning of year	$	1,022,000		$	671,000
Accruals for warranties		1,613,000			1,566,000
Warranty claims settled		(1,079,000	)		(1,228,000	)
Acquired warranty liabilities		80,000			13,000
Balances as of end of year	$	1,636,000		$	1,022,000

Additional Contingent Purchase Consideration

As part of the agreement to acquire a subsidiary by the ETG in fiscal 2007, the Company may be obligated to pay additional purchase consideration of up to 73 million Canadian dollars in aggregate, which translates to approximately $72 million U.S. dollars based on the October 31, 2010 exchange rate, should the subsidiary meet certain earnings objectives through fiscal 2012.

As part of the agreement to acquire a subsidiary by the ETG in fiscal 2009, the Company may be obligated to pay additional purchase consideration of up to approximately $1.3 million in fiscal 2011 and $10.1 million in fiscal 2012 should the subsidiary meet certain earnings objectives during the second and third years, respectively, following the acquisition.

As part of the agreement to acquire a subsidiary by the ETG in fiscal 2009, the Company may be obligated to pay additional purchase consideration of up to approximately $7.6 million should the subsidiary meet certain earnings objectives during the second year following the acquisition.

The above referenced additional contingent purchase consideration will be accrued when the earnings objectives are met. Such additional contingent purchase consideration is based on a multiple of earnings above a threshold (subject to a cap in certain cases) and is not contingent upon the former shareholders of the acquired entities remaining employed by the Company or providing future services to the Company. Accordingly, such consideration will be recorded as an additional cost of the respective acquired entity when paid. The aggregate maximum amount of such contingent purchase consideration that the Company could be required to pay is approximately $91 million payable over future periods beginning in fiscal 2011 through fiscal 2012. Assuming the subsidiaries perform over their respective future measurement periods at the same earnings levels they have performed in the comparable historical measurement periods, the aggregate amount of such contingent purchase consideration that the Company would be required to pay is approximately $9 million. The actual contingent purchase consideration will likely be different.

Litigation

The Company is involved in various legal actions arising in the normal course of business. Based upon the Company's and its legal counsel's evaluations of any claims or assessments, management is of the opinion that the outcome of these matters will not have a material adverse effect on the Company's results of operations, financial position or cash flows.
